The technical field to which the invention relates.

The present invention in General relates to the production of containers and, more specifically, a method and device for simultaneous perforovane and reshaping the bottom of the metal container with the aim of improving the strength characteristics.

Background of the invention

The usual approach in the production of beverage containers, or other containers such as cans for beer or other capacity to pick out a segment on the cover, from 12 to 32 oz) is a two-component technology, including the molding of the housing that contains (usually cylindrical side wall and a bottom, all made from one piece of metal, usually aluminum, and forming the upper part or cap attached to the neck of the body, for example, by means of a double seam or operation rolling. It is important in the design and manufacture of such containers to achieve the necessary balance between minimizing the requirements for materials (such as securing a relatively thin layer of metal) and receiving capacity, which will maintain its integrity and/or shape when exposed to forces that occur when falling or other accidents with containers during transport and handling of containers. Moreover, it is necessary to have capacity that preserve holistically the path and/or form even when their content is under pressure from what content hairouna carbon dioxide or any other gas or due to the high internal temperatures, including in some cases, the temperature of pasteurization.

Conventional molding process beverage containers is that a thin sheet of metal alloy is subjected to a series of operations stretching, smoothing and/or shaping. One of the first actions that are made on a metal sheet, is the process of deep drawing, when the sheet is extruded to form a seamless Cup that is made for setting the initial shape and the inner diameter of the vessel. Then the Cup passes through a series of smoothing rings to eastonite the outer vessel wall to a selected thickness. During these processes of smoothing that is performed by the equipment, usually called machine forming the body of the container, the diameter of the vessel usually remains constant despite the fact that the length of the outer wall essentially increases and the capacity of the tank. In the lower part of the vessel is usually formed recessed or concave domed surface, which is capable of resisting deformation resulting from internal fluid pressure. The pressure at which the recessed surface is deformed or twisted, often called "static pressure you is Ruciane dome" capacity. The bottom of the tank also has a ring-shaped supporting element, which is in contact with the support surface and supports the container in an upright position when laying, the use of tanks and other similar operations.

As indicated above, it is desirable to reduce the amount of starting material required for the manufacture of such containers. One successful method of reducing the amount of starting material, known at the present time, consists in reducing the diameter of the upper and lower parts of the banks and is commonly called "cross-tapering". Reducing the diameter of the upper and lower banks, significantly reduced the use of the material for "cover" banks and even a small reduction of the specified diameter can result in a significant price reduction operations production capacity. There are two diameter for vessels under sadoway and beer, equal to 2 2/16 inches and 2 4/16 inch, commonly referred to as the container 202 and the capacitance 204, respectively. It is now known and there are many other values of diameters. Many manufacturers produce tanks 202 and 204 using the same equipment for forming the body and perform various operations to obtain the upper closing part or "cover" the banks of the appropriate size.

In the lastnosti to the annular support element of the lower part for receiving the containers 204 of the container 202 is an additional stage, known as conversion. The annular supporting element typically has external and internal surfaces, the first of which connects the outer wall of the annular support element, and the second connects the annular supporting element with a domed surface. The data profiles of the outer and inner surfaces are formed in the production capacity and form the outer profile of the dome and the inner profile of the dome. The configuration of the lower part important to facilitate reduction of the material used as to increase the strength characteristics can be used in various geometric configurations. For example, the lower part may be in the form of improving the characteristics static pressure inversion of the dome and reducing the risk of damage to the vessel which may occur due to falling capacity on a hard surface during storage during transport or use. This resistance in the fall can be described as the total drop height at which the bottom portion is deformed so that the capacity can't stand on a smooth surface or stacked in piles on another container.

The process, known as "performanee", used often. In this process, the inner dome-shaped profile of the lower part of the vessel is attached to this geometry is practical form, which has improved strength characteristics. Performanee leads to increased strength beverage containers in relation to the fall and warping. The external profile of the dome is also often changes shape, that is, re-profiled to improve the possibilities for stacking of containers for beverages and improvements in the strength of the containers. In addition, performanee/conversion is intended to manage the growth of the dome" - a condition where the capacity is higher after passing through the process of pasteurization. As mentioned above, in order to have plant as cans 202 and cans 204, the lower part of the banks can transfer, that is, the external profile of the dome may be re-processed (reduced diameter) with the aim of obtaining the vessel 202 to drink from the container 204 for drinks.

Conventional enterprise for the production of cans, as mentioned above, have expensive capital equipment and often produce hundreds of millions of beverage containers per year. Accordingly, it is advantageous to have a company able to produce as tank 202 and the capacitance 204 for drinks, to provide consumers with both types of cans without the need for a separate production for each type of cans. As banks 202 and banks 204 for drinks can be made using the same equipment the provision for the formation of the corps, that leads to the fact that the company needs only to at the end of the production line to choose to perform or not to perform the conversion to get the dome 202 or 204.

Currently, when factory want to combine the two processes in the manufacture of cans 202 for drinks with improved properties of the dome, you must use two machines located sequentially. First use of the machine for perforovane, which generates a corresponding internal geometric profile of the dome, necessary to provide different strength characteristics of the dome, as mentioned above. For operation of the reformation should the operation of the conversion, during which the equipment for conversion is used to form the outer profile of the dome, which is needed for capacity 202 for drinks.

As it is clear to a person skilled in the art, the presence of additional machines in the factory is an additional element of expensive capital equipment, maintenance of which requires a significant annual cost. Moreover, additional equipment takes up valuable space in the limited closed space manufacturing enterprise. In addition to the usual performancing equipment currently used on the Oba is " a plant for the production of tanks, typical costs associated with the wear mechanisms and tool, which can affect the performance in case of irregular maintenance. It is desirable to reduce such maintenance as maintenance provides for the stopping of the equipment and also requires personnel to perform this maintenance and spare parts, which increases the overall cost of the produced beverage containers.

One example of attempts at solving the aforementioned problems is described in U.S. patent No. 5934127 issued by Ihle ("patent '127") which describes a device for perforovane bottom of the tank, using the rotation of the containers to rotate the tank when performanee its lower part. Unlike the invention described in patent '127, in the present invention is not required to rotate the body of the vessel, this body is held in a static position while rotating the device to perform perforovane/conversion relative to the longitudinal axis of the vessel. This configuration has several advantages, including that offered a stand-alone unit, requiring no external stops, levers or mechanisms to actuate tools for reshaping or tools for perforovane. This unit is driven re what emeniem capacity tool or the move tool in capacity, or both movements. This unit is easily installed on existing edging/performacne/pereprofiliruja/obitochnyi machines, usual for companies producing capacity. Holding the housing capacity in a static position is advantageous because of transport from the rotating machine capacity is relatively difficult. Moreover, the instruments relevant to the present invention, it is easy to install in place of the existing tools for perforovane and conversion of vessels, while the device described in patent '127, requires the purchase and installation of a totally different machine.

Accordingly there is a need for a device and process which can produce a metal container that does not require a separate machine or a separate process for the implementation of perforovane and reshaping end of the tank. Accordingly, it would be useful to have a process that reduces the total number of required maintenance in a manufacturing company and reduces the wear mechanisms and tools.

Brief description of the invention

In the present invention solved the above problems, and it has other advantages which are useful and beneficial from the standpoint of cost efficiency for the company producing capacity. More specifically, the present invention features methods and device for simultaneous perforovane and reshaping the bottom of the tank.

According to one aspect, the present invention features a device that includes the device perforovane capacity, which has a roller block, aligned with the opposing him lower part of the container, the roller unit has an outer annular edge and the front surface. Means of rotation of the rotating device perforovane capacity, in this case the vessel is maintained in a static, non-rotating condition. In one embodiment, the implementation of the two pairs of external pereprofilirovanii rollers protruding beyond the front surface of the roller unit in a direction essentially parallel to the longitudinal axis of the vessel and are located close to the outer annular edge of the roller block. Pair perforowanych rollers extended beyond the front surface of the roller unit and shall be of such dimensions to interact with the inner surface of the annular support element. Deflecting means cooperating with a pair of perforowanych rollers, and when the bottom of the tank presses on the annular flange of the pair perforowanych rollers, performacne rollers are moved outwards towards the outer annular edge of the roller unit, and the internal profile of banks is created on the inner surface of the annular support element pair perforowanych rollers and externally the th profile of banks is created on the outer surface of the annular support element two pairs of external pereprofilirovanii rollers.

In one implementation of the invention under the application of force to the pair of shoulder perforowanych rollers each of perforowanych roller stands out, at least 0.1 inch. Depending on the type of vessel and the preferred geometric shape of the tank, this distance may be in the range from 0.05 to 0.1 inches. Each roller pairs is performed with the opportunity to interact with the liner, which is oriented in the transverse direction relative to the longitudinal axis of the vessel. Tools deviations may include at least one spring, interacting, at least one roller of the pair perforowanych rollers. Performacne rollers can be moved in at least two different directions, when the flange on a pair perforowanych rollers force is applied. The device reformation capacity may also have a block sliding contacts, which is located between the roller unit and the installation axis.

Another aspect of the present invention is that a device which can be selected or to perforovane inner dome-shaped part of the lower part of the vessel with subsequent conversion of the outer dome-shaped part of the lower part of the vessel or for simultaneous execution of both operations. More specifically, the pair perforowanych Alikov can choose to be removed and external pereprofilirovanie rollers can be independently used to reshape the outer surface of the annular support element. Thus redesigned the rollers are made with the possibility to selectively remove and replace the outer support rollers, with performacne rollers together with the outer supporting rollers serve to perforovane the inner surface of the annular support element capacity. Means of rotation may include an axis associated with the engine. There are tools that are used to hold the container in a stationary, essentially stationary, and in one embodiment of the invention, they include a mandrel, which is inserted in the interior of the container to engage the inner surface of the container to prevent movement. Alternatively, it is clear that professionals in this field may also be offered other types of mechanisms that can hold the container in a static position without damage (deformation) of the vessel during the operation of perforovane/conversion on the bottom of the tank.

According to another aspect of the invention proposes a device for perforovane bottom of the tank. The device comprises a mandrel supporting capacity, essentially in a stationary position, the device perforovane, tool rotation and tool deflection. The device perforovane contains the main roller block and at least two per the grading roller, protruding outward from the main roller block in a direction essentially parallel to the longitudinal axis of the vessel and located aligned with the bottom of the tank. Tool rotation interact with the device perforovane order rotation device perforovane around the longitudinal axis of the vessel. Tools deviations correlated with performacne rollers so that during the application of pressure on the annular flange perforowanych rollers, at least one of perforowanych rollers is moved outward in the direction of the annular edge of the main roller block for engagement with the inner surface of the annular bottom of the tank and turns the preferred geometric profile of the lower part of the vessel.

In one implementation of the present invention, the preferred geometric profile of the outer surface of the annular bottom of the tank is formed pereprofilirovanie rollers, and the preferred geometric profile of the inner surface of the annular bottom of the tank is formed performacne rollers. Each performatory roller can interact with a liner, which is oriented in the transverse direction relative to the longitudinal axis of the vessel. Tools deviations may include plastic the thuja spring or similar mechanism, known in the art. The roller unit may also interact with adjustable block sliding contact and the alignment axis.

Another aspect of the present invention is a method of simultaneous perforovane and redevelopment, the bottom of the metal container. The method includes the steps of holding capacity, essentially, fixed, static position assurance device for perforovane, a rotation device for perforovane and engagement of the annular support element in a metal container with a device for perforovane, which is essentially simultaneous performanee the inner surface of the annular support element and reshaping of the outer surface of the annular support element. In General, the container has side walls that are located around essentially the longitudinal axis, and the device perforovane rotates relative to the essentially longitudinal axis. Device for perforovane in one implementation has a roller unit having an external annular edge and the front surface and the front surface aligned with an opposing her lower part of the vessel. Device for perforovane also has two pairs of external pereprofilirovanii clips that protrude outwards relative to the front surface is ti roller unit, and a couple perforowanych rollers, which extended over the front surface of the roller unit and have a flange size, in order to hold the annular support element of the lower part of the vessel. Device for perforovane further comprises means variances, which communicate with a pair of perforowanych rollers, and when the front edge of the neck of the container presses the flange, at least one of perforowanych rollers are moved outward toward the annular edge. External reference element engages the device to perforovane so that when the outer support element engages behind the flange perforowanych rollers, essentially simultaneously effected perforovane the inner surface of the annular support element and reshaping of the outer surface of the annular support element.

In one implementation of the invention under the application of force to the shoulder perforowanych rollers these rollers are moving outward at about 0.1 inches, although this dimension may obviously be increased or decreased depending on the geometric profile of the vessel, to which is applied performanee. In one embodiment, the implementation phase rotation comprises a rotation device perforovane using the engine. In another implementation stage withheld what I includes the availability of funds hold, such as a mandrel, which engages, at least the inner surface of the side walls of the container. In another implementation, the device perforovane may also have adjustable plate sliding contact disposed between the roller unit and the installation axis. In another implementation, the pair perforowanych rollers cooperates with the liner, which is oriented in the transverse direction relative to the longitudinal axis of the vessel.

Another aspect of the invention is that the improved geometric profile of the lower part of the vessel that is being done to improve durability and cost optimization of materials. Thus, in one implementation of the present invention, it is proposed capacity, geometric profile which is determined performanoe area of the inner surface of the annular support element having a relatively "hook" shape. "Hook" performancing groove essentially captures the dome, protecting walls from expanding and controlling the increase of the dome, which can be no more than about 0.03 inch. The outer surface of the annular support element can also be converted, while additionally improving the strength and optimizes the material flow.

Another aspect of the present from which retene is what a device for perforovane end of the tank, and the operation is the part of the device, which communicates with the container, the container has an outer wall located around the longitudinal axis. Preferably, the device contained a mandrel supporting capacity, essentially in a stationary position, the device perforovane, tool rotation and tool deflection. Device for perforovane contains roller unit and at least two perforowanych roller and at least two pereprofilirovanii roller, which jut out from the main roller block in a direction essentially parallel to the longitudinal axis of the vessel and which is aligned with the bottom of the tank. Tool rotation interact with the device perforovane order rotation device perforovane relative to the longitudinal axis of the vessel. Tools deviations interact with performacne rollers, and, when the annular rib perforowanych rollers force is applied, at least one of perforowanych rollers moves outward toward the annular edge of the main roller block for engagement with the inner surface of the annular bottom of the tank, resulting in the preferred geometry of the mini-profile of the bottom of the container.

Thus, in one implementation of the present invention proposes a device adapted for simultaneous perforovane and reshaping the bottom of the tank, and the tank has an external wall that is located around the longitudinal axis, the lower part is connected to the side wall and has a ring-shaped supporting element with inner and outer surfaces, the device includes:

A detailed description of the preferred embodiments

While this izobreteny which can have many variants of implementation, in the drawings shown and will be described in detail preferred implementations of the present invention. However, it should be understood that the present description should be considered as an illustration of the principles of this invention and is not intended to limit the broad class of aspects of the invention to the illustrated implementation options.

In Figures 1-9 presents one implementation of the present invention, in which a device 20 perforovane and re-adapted for simultaneous perforovane and reshaping the bottom of the beverage containers. As will be appreciated by specialists in this field, the invention can be used for any type of metal containers and it is not limited to beverage containers, such as cans of beer or soft drinks.

More specifically, Figures 1 and 2 are a front view and top view, respectively, while Figure 3 provides a view in isometric device 20 perforovane and re-appropriate the present invention. The device 20 perforovane and conversion usually has a roller block 24, which in turn contains an outer annular edge 28 of the roller unit, the front surface 32 of the roller unit and the Central hole 36 of the roller unit. The device 20 p is the reform and reorganization also includes a block 40 of the sliding contacts, which has an external annular edge 44 of the block sliding contacts, the front surface of the block sliding contacts and the Central hole 52 of the block sliding contacts. Each roller unit 24 and the block 40 of the sliding contacts are attached to the installation axis 56 through the Central hole 36 of the roller unit and the Central hole 52 of the block sliding contacts. On the roller block 24 is a pair of perforowanych rollers 60, with the outer edge 64 and an annular flange 68. Also on the roller block 24 has two pairs pereprofilirovanii rollers 72, which have the outer edge 76. The installation axis 56 is connected with the engine or other source of energy, which gives the installation axis 56 of the rotational movement.

In Figures 4-7 shows the cross-sections A-a, b-b, C-C and D-D of the device in Figures 1-3, respectively. As illustrated in Figure 4 performacne rollers 60 are attached to the inserts 84 perforowanych rollers, which act to block 40 of the sliding contacts. Liners 84 perforowanych rollers are in block 40 sliding contact angle α in relation to an imaginary plane that is perpendicular to the front surface 32 of the roller block and centered with respect to a pair of perforowanych rollers 60. In one implementation liners 84 perforowanych videos I have are ball bearings linear motion. Springs 86 (Figure 5) are located in the Central hole 36 of the roller unit and interact with a pair of perforowanych rollers 60 in order to put pressure on performacne rollers 60 in the direction from the block 40 of the sliding contacts. When preformationism rollers 60 a force is applied, performacne rollers 60 at the same time moving towards the block 40 of the sliding contacts and also towards the outer annular edge 28 of the roller unit. Each performatory roller 60 is connected with the connecting block 88, the connecting blocks 88 are connected by guide pins 92, this ensures that performacne rollers 60 move agreed. Although in the preferred embodiment, the implementation of both perforowanych roller 60 are moving out at the same time, it is possible that at a particular point in time was moving only one of perforowanych rollers 60.

Pereprofilirovanie rollers 72, as shown in Figure 6, include bearing elements 96, which provide the ability to rotate the Central axis 100 pereprofilirovanii rollers. Bearing elements 96 are attached to pereprofilirovaniem rollers 72 with screws 104, the heads of which are superimposed on the bearing elements 96 and prevent the disconnection of the bearing element 96 from pereprofilirovanii rollers 72. Pereprofilirovanii ro the IR 72 in Assembly with the bearing element 96 is inserted into the cavity in the roller block 24 and fastened by means of screws 108 and mounting washers 112, so fixing washer 112 overlaps the bearing element and holds pereprofilirovanii roller 72 in the cavity. In one embodiment, the implement mounting washers 112 are of such size that its outer edge is not in contact with the Central axis 100 pereprofilirovanii rollers.

As mentioned earlier, the wear parts inherent to such production of containers, characterized by great speed and great output. Pereprofilirovanie rollers 72 and associated bearing elements 96 can be removed and replaced relatively easily by removing the mounting screw 108 and the mounting washer 112 to free pereprofilirovano roller 72 and replace it with a spare clip. In one implementation, the cavity has a washer that pushes pereprofilirovanii roller 72. In one embodiment of the invention shown in Figure 7, between the roller block 24 and the block 40 of the sliding contacts are adjusting spacers 98. The size of the adjustment spacers 98 may be selected so as to ensure the necessary distance between the roller block 24 and the block 40 of the sliding contacts.

Next, with reference to Figures 8-10 will be described the operation of the device 20 perforovane and conversion. The figure 8 shows a front view of the device 20 system perforovane and pureprofile the project and the capacity of 116 for beverages mounted on the mandrel 120. The Figure 9 shows the cross-section e-E system with Figure 8. Figure 10 contains a cross-section of the system from Figure 8, which shows the capacity of 116 for drinks in contact with the device 20 perforovane and conversion. In a variant implementation, illustrated in Figures 8-10, the capacity of 116 for beverages mounted on the mandrel 120 in a fixed, stationary position. The mandrel 120 and the capacity of 116 for drinks towards the device 20 perforovane and reorganization until such time as the container for drinks will come into contact with the device. The lower part of the beverage containers has a ring-shaped supporting element 124 with the inner surface 128 and the outer surface 132. The mandrel 120 and the capacity for beverages 116 aligned so that the annular supporting element 124 beverage containers in contact with the annular flange 68 performancing roller. The mandrel 120 and the capacity for beverages 116 continues to move towards the device 20 perforovane and conversion, and the annular supporting element 124 is in contact with the annular flange 68 performancing roller up until performacne rollers 60 is fully included in the interaction with the inner surface 128 of the annular support element 124, and pereprofilirovanie rollers 72 is e engages with the outer surface 132, as shown in Figure 10. Similarly, the mandrel 120 and the capacity of 116 for drinks can be fixed, and the device 20 for conversion moves towards capacity 116 for Nelidov or as a device 24 for conversion, and the mandrel 120 and the capacity of 116 for drinks can move towards each other.

As mentioned above, applying pressure to the annular rib 68 performancing roller causes performacne rollers 60 at the same time moving towards the block 40 of the sliding contacts and towards the outer annular edge 28 of the roller unit. In one implementation, as the capacity of 116 for beverages mounted on the mandrel 120, the mandrel 120 is aligned with respect to the device 20 perforovane and conversion and moves by a preset distance to the device 20 perforovane and conversion that leads to the tank 116 for drinks coupled with device 20 perforovane and conversion. When the capacity of 116 for drinks coupled with device 20 perforovane and conversion, the device 20 perforovane and the conversion starts to rotate. Pressure pereprofilirovanii rollers 72 working to reshape the outer surface 132 of the annular support element 124 and the pressure Performa the internal rollers 60 is used to reshape the inner surface 128 of the annular support element 124. Accordingly, the bottom of the tank 116 for drinks at the same time performatives and re-profiled and she is given the desired geometric shape.

Next, with reference to Figure 11 will be described another embodiment of the present invention. In this implementation, the device 150 to perforovane has components similar to that previously described for the device 20 to perforovane and conversion with one significant difference. The device 150 to perforovane contains support rollers 154 to perforovane. Support rollers 154 to perforovane need to provide support for the outer surface of the annular support element of the lower part of the vessel for beverages during operation perforovane. The device 150 perforovane functions the same as described above, the device 20 to perforovane and redevelopment, where performacne rollers 60 at the same time moving towards the block 40 of the sliding contacts and toward the annular edge of the roller unit in order to apply the appropriate force to perforovane the inner surface of the annular edge of the roller block beverage containers.

Similar to that described above with reference to Figure 6, the rollers 154 to perforovane can be extracted from the roller block 24 after UD is of screws 108 and mounting washers 112, then getting the support rollers 154 to perforovane from the cavity in the roller block 24. Thus, one and the same roller block 24 can be used for perforovane and conversion, as well as when performing only operations perforovane: you only need to replace pereprofilirovanie rollers 72 on performacne rollers 154. This replacement can be done when, for example, it is necessary to make the vessel 204 for drinks. If it is necessary to make the vessel 202 for Nelidov, performacne rollers 154 are replaced pereprofilirovanie rollers 72. Accordingly, for both processes, you can use the same basic equipment, resulting in more efficient manufacturing operations. Moreover, operations perforovane and conversion or only operation perforovane can be performed without the need for a separate manufacturing equipment.

In Figures 12-14 shows a cross-section of the lower dome of the tank 200 for drinks, showing various geometric shapes after operations perforovane and conversion. More specifically, in the Figure 12 shows the corresponding currently known technologies of the lower dome portion 204 of the container 200 for drinks, which has a ring-shaped supporting element 206, which includes an inner surface 208 and the outer surface 210. Three different designs for the x radius R1, R2 and R3 annular support element 206 represent the radius of the annular support element 206 relative to the inner surface 208 in three different vertical elevations. The Figure 12 shows the capacity of 200 for drinks before performing operations perforovane and conversion.

Figure 13 illustrates the lower dome portion 204 of the container 200 for drinks after the operation perforovane, corresponding to one implementation variant of the present invention. After realization of this process perforovane the inner surface 208 of the annular support element 206 includes part 212 having a relatively pronounced "hook" shape. The annular supporting element 206 has a radius R2 which is smaller than any of the values R1 or R3 that defines this hook portion 212. Hook portion 212 improves the strength characteristics of the lower dome portion 204 of the container 200 for drinks and will be described in more detail later.

Figure 14 contains the lower dome portion 204 of the container 200 for drinks after operations perforovane and conversion corresponding to one implementation variant of the present invention. As shown in Figure 14, the outer surface 210 of the annular support element 206 contains pureprofile is nnow part 214, which further reduces the radii R1 and R2 relative to the radius R3 and allows stacking capacity, as capacity type 202. The combination of parts 212 and 214 leads to a more pronounced hook shape that is obtained by reducing the radii R1 and R2, which further improves the strength characteristics of the lower dome portion 204 of the container 200 for drinks.

This preferred geometric shape, illustrated in Figures 13 and 14, created after implementation over capacity 200 beverage operations perforovane/conversion of the present invention, provides excellent strength characteristics capacity 200 for drinks. Excellent strength characteristics include increased resistance to warping that occurs due to the shape, counteracts the distortion, resulting from the action of forces, as described below, changing both internal and external surfaces 208, 210 annular support element 206. The force acting during operations perforovane and re-prevents the movement of holes in the dome outward and at the same time leads to the decrease of the radii R1, R2 and R3, which increases the resistance to stretching and warping. Improving strength, obtained thanks to a special hook form, leads to p is receiving some fixing properties, formed on the inner surface 208 of the ring-shaped support element.

Next "hook" essentially holds the walls of the dome in place and resists stretching, as the radius R2 of the hook is less than the radii R1 and R3. Giving the inner surface 208 of this form leads to the fact that the inner surface 208 resists plastic rolling or stretching which may occur when the capacity of 200 applies excessive pressure, this phenomenon is characterized by an increase of one or more radii R1, R2 and R3. Further, the groove helps to prevent unwinding and stemming from the increase in the length of the tank at any pasteurization process. When the pressure acting on the lower dome portion 204 from the inside of the container 200, it pushes the dome-shaped portion 216 toward the bottom of the tank 200 for drinks. The geometric shape of the dome-shaped portion 216 is such that the pressure applied to the inner surface 208 is sent to the bottom of the vessel 200 to the outer surface 210. When there is pressure, due to the form of the annular support element 206 is unlikely to increase the radii R1, R2 and R3, thus, decreases the probability of stretching or wrinkling.

Further, for clarity, shows the list of components and their associated numbers on the drawings.
