The invention, in General, refers to the capsules containing the ingredients of the drinks, for producing a beverage system designed for use in connection with such capsules, as well as to the method of manufacture of such capsules.
The prior art prior to the present invention relates to the field of capsules that contain the ingredients of the drink (for example, ground coffee, milk or other food ingredients (for example, digidrirovanny soup). By the interaction of these ingredients with the liquid can be prepared drink, or other food products. This interaction may represent, for example, extraction, melting or dissolution. This kind of capsule is particularly adapted to contain ground coffee for preparing a coffee beverage by means of a flow in a tank of hot water under pressure and excretion of coffee beverage from the capsule.
Systems and methods for receiving liquid food from capsules containing a substance, is known for example from EP-A-512470.
The General principle of this extraction process can be summarized as follows:
- Initially closed capsule is inserted between the means of the holder capsules, which are closed watertight way around the capsule;
Means of injecting water into the machine inject water into the cap the Ulu;
Water interacts with the ingredients contained in the capsule passing through the interior of the capsule, and then forced to leave the capsule through at least one hole/perforation made in the second wall.
The ingredients in the capsule are "obstacle" ("seal") in the path of flow of water and, consequently, will cause a pressure drop between the side of the front, over and party in the back by the flow of liquid through the capsule, which is the pressure drop will increase even more during the interaction between the liquid and the ingredients, for example, due to the swelling of the ingredients. Accordingly, it is necessary to ensure that the flow of water actually took place only through the interior of the capsule and that no water can flow from opryskivatel water in the space between the annular covering component and the outer surface of the capsule and then to the issuing orifice device. In other words, any flow of water external to the capsule must be stopped sealing engagement between the annular covering a component of the holder and the capsule and the flow paths between the injectors of the water and letting the drink hole.
Such sealing engagement may be, at least to some extent, achieved clamps gearing between crestlinesales capsules (i.e. ring covering the component and the holder capsules) and lanceolatum the rim of the casing between them.
If the sealing engagement is not functioning properly and the water flows on the outside of the capsule, inside the capsule will not be created pressure sufficient to cause rupture of torn face, or, in the alternative, the pressure will not cause a complete rupture torn edges and, consequently, will result in poor extraction of the substance. In this situation, the water will be derived from making the beverage device, not browseinterval or not fully browseinterval under sufficient pressure with the ingredients contained in the capsule.
You could consider the improvement according to which this sealing engagement is additionally improved by vastlane the inner walls of the annular component koutsokoumnis elastic material. In other words, in accordance with the above approach, the sealing engagement is guaranteed by the structures established on prigotavlivaya drink device, or attached to it. This has the disadvantages that after using a significant number of capsules may be the wear of the installed sealing means that the quality of the prepared drink more and more worse due to the fact that the water passes the seal that is no longer effective in allegada least. In addition, the sealing means may be contaminated with organic remains, clinging to him, that is not quite hygienic and, also, may at the time of extraction to cause damage to the sealing conditions and pressure.
Any "leak" outside of the capsule reduces the build-up of pressure in the capsule. On the other hand, it is well known that sufficient pressure extraction is a key factor for the quality of the coffee type espresso. At the same time consider European patent application number 04025320.5 entitled "Capsule with sealing means, refers to improvements in sealing engagement, located between the inlet opening for the liquid and the exhaust side of the drink in such manufacturing beverage system. The invention is directed to transfer the elastic part sealing engagement with producing the beverage device to the capsule. The advantage is that any elastic sealing component is used only once (i.e. only with the associated capsule), so you can be guaranteed the proper functioning of the seal, and the sealing component may not experience any hygienic problems.
The present invention relates to another improvement of simultaneously considering European patent application number 04025320.5, having St is her goal to improve the seal between the capsule and sealing component, so in order to ensure watertightness during cooking. Indeed, it is important to avoid any potential leakage of fluid between the sealing component and the rest of the capsule, in particular, through the establishment of good communication between them.
In addition, it is also important that the sealing component has been integrated into the capsule using a process that may be embodied in a large industrial scale, to be highly reliable with a minimum number of defective products and also be cost effective.
This problem is solved by the features set forth in the independent claims. Dependent claims additionally develop the Central idea of the present invention.
In this regard, the method according to the invention is intended to provide a sealing component in the case of a capsule containing beverage ingredients, intended for introduction into producing the beverage device in which a liquid under pressure enters the capsule to interact with the ingredients in the capsule and removal of the beverage from the capsule, characterized in that it comprises the stages, which provide housing and Inuktitut at least one sealing material by a method of injection molding on at least the area of the external surface to the pus for forming a sealing component, hermetically attached to the case.
To put it more specifically, the injection of a sealing material (or sealant) to form a sealing component offers many advantages. First of all, the adhesion of the sealing component can be significantly improved by attaching pre-made sealing component. The result can be prevented leakage of fluid between the sealing component and the body of the capsule, and the extraction conditions can better be managed and maintained from capsule to capsule (i.e. the best repeatability conditions of cooking). The sealing component is more firmly attached, as part of the capsule is less risk that the sealing component will otkroetsja or will be displaced, when used in variadic drinks machines, which are not intended for installation capsules without sealing component and, therefore, also reduces the risk of failure.
In addition, it offers more opportunities for the production of capsule case with simpler or more diverse forms. The method is also more bystrowiana, more cost-effective than joining and attaching the sealing component mechanical, welding and/or adhesive means, and may be implemented effective the way with high performance and a large industrial scale.
Preferably, the sealing material is made of a material different from material of the housing. More preferably, the sealing material was softer than the material of the body.
In a preferred embodiment, the body is made with lanceolatum rim, and the stage injection contains the stage at which carry out the injection molding of a sealing component on this lanzoprazol the rim. Planteary rim represents the area in which the capsule is clamped covering components (e.g., bell-shaped component and the holder capsules, closed tightly around the capsule) making the beverage device. Because the injection molding of the sealing component is made of a softer material than the housing in the area lanzoprazole rim, then it can be compressed in such a way as to compensate for irregularities, the clearances are within tolerance or gap and so on, in order to maintain watertightness under pressure cooking in the chamber for capsules.
Planteary rim may, in addition, contain the mounting section and the supporting section. The mounting section is located so that during the injection of the sealing material component can flow on the mounting section in such a way as to improve the connection between the most normal punctures and the speaker component and the housing.
The fastening section can be formed from a partially twisted plot. Twisted plot may contain a hole, such as a circular hole, so that the plastic was numb during the injection. Twisted plot can be formed during operation deep drawn casing, which is preceded by the injection molding of a sealing component or, alternatively, is formed in a separate molding operation lanzoprazole rim after deep drawing of the cavity in the body of the capsule. Preferably, operation of the injection molding sealing component consisted of injection molding plastic under high pressure. The body of the capsule is clamped from the inside, i.e. from the side of the cavity, and from the outside, i.e. on the outer side of the side wall of the body molds for injection molding, and these molds define the injection chamber, ogranichivaya the quantity to be filling a sealing material. The sealing material may be injection under pressure, which exceeds 500 bar (5×107n/m2), and is preferably between 500 (5×107n/m2and 2000 bars (2×108n/m2), more preferably between 800 (8×107n/m2and 1500 bars (1.5 x 108n/m2). The time of injection of full-time is short and typically less than a second. Immediately after the injection of the sealing material give a few seconds to cool for curing, generally between 3-8 seconds.
The material for the sealing component should be selected from among a thermoplastic elastomer that can be elastic, resistant to heat and pressure and is suitable for injection molding. Preferably, thermoplastic material usually consisted of a thermoplastic elastomer ("TPE"). More preferably, the THIRD consisted of an elastomer based on polypropylene.
As mentioned, at the preliminary stage of manufacture of the body of the capsule can be pre-formed by deep drawing a metal or plastic sheet. Deep hood shell capsules can be carried out in one stage or stages, forming the final major open cavity, allowing it to fill her food ingredients. During the operation (operations) deep drawing can be formed planteary rim, fastening means, in particular curled edge of the rim or other important functional profiles.
In addition, can be performed, at least one local deformation of the side wall of the housing to create an additional fastening means for germetezirujushie what about the component, in particular lip area sealing component that extends along the side wall of the housing. Local deformation (local deformation) can be made in the side wall of the housing in such a way as to create, for example, one or more shaped arc protrusions of the casing wall projecting inward of the sealing material component. Referred to local deformation (local deformation) can be performed during injection molding or cooling the resulting injection molded sealing component. On another subsequent stage of the case is filled food ingredients, such as roasted and ground coffee.
The body of the capsule may contain aluminum. This can be only the aluminum layer or a combined layer of plastic and aluminum, such as polypropylene and aluminum.
The invention also relates to the manufacture of a capsule containing beverage ingredients, intended for introduction into producing the beverage device, i.e. between the covering capsule components, in which fluid under pressure enters the capsule in order to interact with the ingredients in the capsule and remove from capsules drink. The capsule includes a housing with an attached sealing component. Sealing component dedicated to superior quality products is Chen, to ensure watertightness between the capsule and at least pressing surface generating device, i.e. one of the covering device components. The method includes the stages, which provide housing, fill in the case of food ingredients and tightly close the case. The method also includes the step on which Inuktitut at least one sealing material by a method of injection molding on at least the area of the external surface of the body to form a sealing component, hermetically attached to the case.
In the next step, following the step of filling food ingredients, along outer faces lanzoprazole rim weld the membrane to close the capsule. The sealing membrane can also be made from aluminum or a laminate of plastic and aluminum.
The invention also relates to a particular system injection system for injection of sealing material on the surface of the shells of capsules manufactured according to the method according to the invention.
This system contains:
the first component of the mold for injection molding, containing at least first and second injection side for placing many of the buildings capsules,
at least W is Roy component of the mold for injection molding, configured to close the first component of the mold for injection molding and to be entered in many buildings capsules;
at least the first tool replacement housing, configured to replace the buildings capsules on one side from among the first or second injection of the parties, while running injection molding the sealing material on the bodies of the capsules on at least one other injection side of the first component of the mold, while the first and at least second components of the mold for injection molding are movable relative to each other so as to permit the closing of the second component molds alternately the first and second sides of the first component of the mold for injection molding.
Therefore, according to this particular system injection molding shells of capsules can be performed with high performance and automatic mode.
To put it more specifically, the first and second sides of the first component molds contain a number of cavities for placement of buildings capsules, whereas the second component of the mold contains a number of mandrels for introduction into the body of the capsules when the joining component molds.
Other dependent claims izaberete the Oia further develop this specific system to perform the method according to the invention.

Note that in the following description, the invention will be explained with reference to a specific design of the capsule, i.e. the design, according to which the capsule contains a Cup-shaped housing base and the covering is made of foil component. However, it should be understood that there may be other constructions capsules, such as, for example, caps the crystals, having a biconvex shape with two essentially adjacent and opposite each other walls (e.g., foil), sealed, for example, the annular edge. In General, the capsule according to the present invention contains at least two located opposite each other component-walls (faces), which are connected to each other at their respective edges to form a sealed region lanzoprazole rim, thus covering a sealed inner space.
This embodiment of the invention showing the holder (13) capsules having relief elements (12), which are designed to break and to punch made of foil component (5), which seal the Cup-shaped housing base (4) capsule (1). This tearing is made of foil component (5) can occur as soon as the pressure inside the capsule exceeds a certain threshold value. Note that the relief elements can have any protruding shape that can cause a controlled tearing made of foil component. As examples are mentioned only pyramids, needles, convexity, cylinders, elongated ribs. Relief element may also be in the singular.
Figure 1 shows the state in which this kind of kapsa is and placed on the holder (13) capsules, made of foil component (5) rests on the relief elements (12) of the holder (13) capsule, and a Cup-shaped housing base (4) capsule (1) is partially surrounded by a circular wall (25) covering the component (9) producing a beverage device. Shown covering component may be in the form of a bell.
There may be other forms in which the design of the inner contour (deepening) covering component, in General, adapted to essentially conform to the contours of the capsule (1).
Thus, the holder (13) capsules (also representing the covering component and cover component (9) can be selectively cover covering the capsule (22) space when translating from an open position in covering the capsule position.
Note that the foil component (5), as shown, is not necessarily exactly flat due to a certain excess pressure in the capsule, which excess pressure is created, for example, through the introduction of protective gas in the production of filled capsules and during the evolution of a gas of the ingredients of the food product after sealing, for example, carbon dioxide from the coffee.
Covering (bell-shaped) component (9), in addition, contains an annular pressing surface (18) and the hole (20) of the intake at the s for the fluid, such as, for example, hot water under pressure into the system (14) of the injection water, which split the image set (e.g., screwed) to the bell-shaped component (9).
The system of injection water may contain one or more perforating elements (blades, pins, etc.) (24)for performing one or more apertures in the top wall (17) of the capsule (1) when approaching holder (13) capsules and bell-shaped component (9) with each other, for example, by using a manually-operated or automatic closing mechanism. Channel (19) passes through the injection system and leads into the chamber (22) covering the component (9) so that water can be enjoyed in the inner part of the capsule (1) after the inner part of the capsule (1) are perforating elements (24).
Capsule (1) contains the mentioned top wall (17), side wall (7) and glanceability rim (6), made of foil component (5) is sealed at the above-mentioned lanzoprazol the rim (6), hermetically clogging Cup-shaped housing base (4) capsule (1). In addition, there are other possible designs for the capsule when the capsule can be sealed and contains the above mentioned ingredients.
According to the present invention the outer surface of the capsule (1) is a specialized vodone nicely sealing component (made of a sealing material (8), hereinafter referred to as "sealing component". Sealing component (8) can be compressed, more preferably elastic.
The material for the sealing component may be a suitable injection moldable thermoplastic elastomer.
As more clearly seen in figure 2, the capsule according to the invention contains planteary rim (6) with the supporting section (60) for sealing the component and partially twisted boundary area (61)forming a mounting area for a sealing component. Support section (60) is mated with the housing (4) at an angle that is slightly greater than 90 degrees when the housing has the shape of a truncated cone). Planteary rim, as well as the base surface (70) of the side wall, puts on himself annular sealing component (8). To secure the sealing component on lanzoprazol the rim of the sealing component extends in the direction of the partially twisted section (61) of the connecting section (80), which is injected into a partially twisted section (61) of the rim. Rolled edges form a "hook" for a sealing material, which thereby strengthens the connection and also the resistance between the sealing component and the rim. Outside partially twisted participants is a (61) sealing component (8) extends along the supporting section (60) lanzoprazole rim sealing section (81), which can last lip section (82)is mounted on the base surface (70) of the side wall of the housing. The sealing section (81) and the sleeve section (82) can form surface having different angles of inclination, or can be interfaced in a single continuous concave or flat inclined surface. Form a sealing component (8) in the form of a wedge-shaped profile is selected to provide a sufficient mass of material to compensate for irregularities, gaps, or other gaps between the capsule and covering or bell-shaped component. Because the waterproof seal can also be obtained dynamically, that is, through the effect of pressing the sealing component water under pressure, the shape, size, and weight of the sealing component should be sufficient to ensure that it is deformed, thereby elastically Teck and properly fill the remaining holes in the build-up of pressure during cooking.
Figure 3 shows the state in which the covering component (9) and bracket (13) of the capsule shown in locking engagement under pressure with the rim and due to the fact that water flows into the inner part of the capsule and the pressure in it increases, pyramidal relief components (12) of the holder (13) capsules bore holes made in Ivolga component (5) of the capsule (1). After insertion into the capsule of the blade elements (24) opryskivatel (14) water pre-created perforated holes (16) in the top wall (17) of the capsule (1). When inside the capsule created sufficient pressure fluid, a drink made from ingredients contained in the capsule can be released in small cracks or perforated holes created when the gap is made of foil component (5) relief items (12).
In the first step of the method (not illustrated in the drawings), produce the housing (4) capsules. The enclosure can be made with pre-formed lanceolatum rim (6), which remains open for injection of sealing material component in the subsequent stage of injection. Case (4) can be pre-formed by deep drawing a metal sheet or team details of multiple layers, including metal, such as aluminum, and plastic, for example polypropylene, and, ultimately, binders and/or lucky. Depending on the complexity of the shape of the hull and the depth of the cavity deep drawing of the sheet may be carried out at more than one stage. In addition, the body cavity and glanceability rim can be formed during the same operation or, alternatively, during separate operations.
Figure 4 is 5 show the operation of injection of the sealing component (8) on the pre-formed body (7). The housing can thus be placed between the Assembly unit (30) of the mold for injection molding. The Assembly unit of the mold usually contains two components of the mold, covering the component (31) of the mold and covered component (32) of the mold, which are tightly gathered around the body of the capsule and injection space (35) for sealing the material to be injection inside for education sealing component. Covering component (31) of the mold surrounds the outer side wall (7)and top wall (17) of the housing, and usually also dissociates volume (35) for sealing a component that is subjected to injection on lanzoprazol the rim (6) and further extends to the line (34) of the connector, which may be located, for example, essentially on the edge of the partially twisted section (61) of the rim to allow easy removal of the housing from the mold after injection. Covered component (32) of the mold is inserted inside the cavity of the housing and corresponds to the outer shape lanzoprazole rim (for example, the lower surface of the rim) to the line (34) of the connector.
Preferably, the Assembly unit (30) of the mold stretched along the entire side (7) of the housing and has a relatively high mechanical pressure on the side wall (7). Benefits include double
First, the injection is performed at a relatively high pressure for a short period of time, therefore, must be received sealed design of the injection seal, in particular along the line (34) of the junction between the outer side wall of the housing and the topmost point of the sealing component.
Secondly, the pressure may also be effective for smoothing the outer surface (73) of the side wall of the housing. Prior surgery deep drawing tend to create folds on the surface of the side wall by a General truncated shape of the hull. Therefore, the mechanical pressure exerted covered and covering the molds directly on the complete opposite surface of the side wall (7), allows you to smooth wrinkles and eliminate or at least greatly reduce this visible defect.
The injection takes place, at least through one small injection feeder (36). The opening of the feeder at the entrance to the injection space may be on the order of 0.5-1 mm Injection is performed at high pressure, i.e. in the middle between 700-1500 bars (7×107to 1.5×108n/m2within less than a 1.01 seconds, usually 0.01 seconds. Plastic is injected inside at a temperature above the glass transition temperature. The preferred thermoplastic elastomer suitable for all kinds of what is REQUIRED. The obtained sealing component (8) allow to cool for at least several seconds, typically 5-10 seconds before the Assembly of the mold open again, and remove the housing. Cooling can be facilitated by the refrigerant, which circulates in the cooling circuit Assembly unit of the mold in order to reduce the curing cycle for sealing the component.
Figures 6 through 10 show in detail the structure (40) covered mold for injection molding according to a possible variant implementations of the invention. Design (40) covered molds can be installed impermeable manner on the frame (41). It contains the mandrel (42) with the end, which essentially corresponds to the internal body cavity of the capsule, as illustrated in Fig. Inside the mandrel is provided a movable eccentric podavlivaya Assembly unit (43), as illustrated by figures 9 and 10. Eccentric Assembly unit contains two podavlivaya component (44), (45), installed with the ability to slide along the radially oriented slots (37), (38) of the mandrel (see Fig.9). Prodavlivayutsya components (44), (45) are driven advancing/atmodas back through the longitudinal slot of the plunger (46), which moves back and RR is red along the longitudinal axis of the mandrel. The Central plunger has plots (47), (48) of the slope that lead to the action prodavlivayutsya components (44), (45) in their opposite, radial sliding movements along these slits.
As illustrated in figure 10, when the plunger is pushed up, prodavlivayutsya components (44), (45) is moved in the radial direction against a side wall (7) of the housing (4) and thus cause the side wall of the housing of the capsule to be deformed outward in accordance with the shape of the arc of the teeth (71), (72) (see Fig), which are in sealing component (8) (Fig.10). These teeth may be formed at any time after the body of the capsule is inserted on the mandrel and before the injection material has hardened. Preferably, the teeth were created immediately after the injection, for example, after 0.5-1 second after termination of injection.
Teeth (71), (72) improve the fixation of the sealing component on the side wall of the base area, which is critical and where the sealing component has a tendency to detach from the housing. As a consequence, it also provides to some extent a more watertight seal, preventing the risk of leakage at the interface between the sealing component and the housing.
It should be noted that the tooth (teeth) can (can) beclobrate different ways, who can think of the specialist in the art and that the present invention refers to industrially applicable method only for the sake of illustration. In addition, the teeth can take various forms, such as a pin, hump, etc
Figures 11 through 14 illustrate a possible injection system installation to perform injection cycles with high performance. Below will be explained the General principle.
11 is a General system injection setup that can handle two parties injection Assembly units running simultaneously on opposite sides. The principle is based on cubic covering component (60) of the mold for injection molding, which contains four injection side(61), (62), (63), (64) the mold and can be rotated by 90 degrees around the Central axis (65)to move them to the side sweep 90-degree increments. Each side covering component of the mold includes a number of cavities (600) of the mold for injection molding, intended for the individual to enter buildings capsules. These cavities are normally distributed on the side of the mold according to a predefined grid, preferably across multiple rows and columns, for example in grid squares 7 rows by 7 columns, the giver, so the m way a total of 49 individual injection positions. The grid and the number of rows and columns in the grid can vary depending on the required performance.
Cubic covering mold (60) for injection molding is associated with two covered molds (66), (67) facing in opposite directions (61), (63) cubic covering component of the mold. Covered in mold (66), (67) can make reciprocating movement relative to the cubic molds (60)to be able to open and close the sides of the cubic cavities of the mold for injection molding. Covered in mold (66), (67), in addition, contain the covered mandrel (42) in the amount and according to the distribution, corresponding to the number and distribution of injection of the parties.
In the direction orthogonal "injection direction I" (i.e. the direction in which the Assembly unit of the mold are closed simultaneously by the cube of the mold), are converted to the other two opposite sides (62), (63) cubic mold means (68), (69) for storage and transport, designed for automatic loading/unloading of the buildings in the cavity (600) of the mentioned parties. These tools storage and transportation can contain region (680), (61) download arranged in such a way as to put "naked" body capsules (corps performed without injection molding sealing components)available in the grid squares, and the area (682), (683) storage buildings, arranged in such a way as to put a "sealed" enclosure capsules (i.e. housing for them injection molded sealing components). Between these areas are multi-axis robots (684), (685)having a layout with at least three directions in order to, respectively: (a) to unload the sealed enclosure for a given model at the same time from a full injection of the parties, (b) transporting a sealed enclosure of a given grid region (682), (683) storage buildings, (c) remove the bare hull of a given mesh simultaneously from the field (680), (681) download and (d) to transport and place them in the empty cavity of the injection of the parties moved so to be paid to the means of storage and transport.
Multi-axis robots (684), (685) can contain individual means of suction, such as means of suction using a vacuum to capture, transport and release of all buildings at the same time.
Fig illustrates the cycle of the injection molding Doherty nets J1, J2, injection molding which is performed simultaneously. Other operations of loading/unloading can be carried out simultaneously during the injection molding of these parties (61), (63). On the stage A robotic tools are taken out of a sealed case of full parties (62), (63). On stage In robotic tools then transported and unloaded a sealed housing in the area (682), (683) unloading. On stage With robotic tools take a new pending grid "naked" wings of the capsule (e.g., 49 buildings, located in grid squares 7×7) of the areas (680), (681) storage buildings. Then at stage D, shown in Fig, robotic transport means and load the captured party "naked" buildings in the empty injection side (62), (64) cubic component (60) of the mold. Stages A-D can be implemented at a time when the other two parties of the buildings on two adjacent sides of (61), (63) is the injection molding of the sealing components. Consequently, it can be achieved much better performance, since almost every about 10 seconds may be injection molded sealing components in two batches 49 buildings (and hence in the amount of 98 buildings).
The injection system, as shown in Fig the arts from 11 to 13, can be simplified, forming only a single station load/unload with only one covered the mold for injection molding.
As illustrated in Fig, the method includes one or more of the steps (100) deep drawing the body of the capsule, injection molding (110) sealing component (or "rings"). At the next stage (120) case fill of food ingredients, and finally, at step (130) on the outer face of the supporting section (60) lanzoprazole rim are welded, for example by welding by heat or ultrasonic welding, the membrane (5). At any appropriate time during the manufacturing process can be provided by additional steps, such as placing and attaching the filter inside the housing and/or membrane (5) before or after the deep drawing of the hull.
The present invention encompasses other possible variations. For example, the sealing component may be formed from two or more injection materials having different hardness. For example, in the first case can be obtained by injection molding the inner layer of the first material. Then this inner layer may be formed on top of it the outer layer of a second material softer than the material of the inner layer. The inner layer may be present to t the th, in order to improve the adhesion of the second material. The outer material may be softer in order to reduce the closing force for closing the covering components producing the beverage device on the capsule.
In another possible embodiment, illustrated in Fig, the body of the capsule can be formed from plastic. Preferably, the case was also obtained injection molding. Thus, the injection molding of the housing and the sealing component can be implemented jointly (step 140). The casing may be of plastic material with a higher young's modulus than that of the sealing component, but these two materials must be compatible to each other. An example of a suitable material for the housing and the sealing component is a TPE (Thermoplastic elastomer).
