The present invention relates to ventilation panels, which may have wide application, especially for the manufacture of packaging for pizza delivery; packing box, comprising as components such panels, ventilation system, and method of manufacturing the ventilation panel.

Panel used for making boxes, drums, cans, baskets, pallets, boxes, containers, etc. that need to be manufactured with the ability ventilation. Many of these types of containers can be used for storage of products, in this case, the questions ventilation or isolation (or both) are of great importance. Both these issues are of great importance when developing packaging for fast food (fast food).

Packaging for products fast food does three things. Such packaging, for example, cardboard box or carton made from other materials, must keep heat contained in the product should prevent rasisanie product resulting from the condensation of water vapor on the inner surface of the packing, and to be inexpensive, because such packages are usually disposable.

In General, widely used currently packing solve the third problem in combination with only one of the first two. I found it hard to create such packaging is, which would simultaneously satisfy all three of these requirements.

The currently used packaging can not solve all three of the above tasks, partly for the following reasons. During transport of the packaging inside the product dissipates heat away from the product and packaging, and the steam enters the atmosphere inside the packaging. Packing cooler than the product. The hot steam from the product rises vertically above the product towards the cover of the packaging. Once in contact with the lid, the steam condenses into water droplets, transferring heat to the package. The condensed water is now able to fall back on the product, which leads to his rusciani and reduce the taste.

Application packages from polypropylene, an attempt was made to solve the problem by keeping the heat inside the package, due to the high insulation properties of polypropylene. However, after some time, the heat comes out of the packaging, thus, the condensate is formed on the inner side of the packaging on the product.

Another well-known option packaging is the packaging made of corrugated cardboard. Corrugated cardboard is used for the manufacture of packaging due to properties inherent in its corrugated structure. The corrugated structure has sustained the sufficiency and the ability to distribute the forces applied parallel and perpendicular to the configuration of the corrugated structure. Under the application of a corrugated structure, the mechanical strength in the direction of the grooves they are under compression and acting as columns, resist the compressive force. Thus, the corrugated structure increases the strength of the panel against compression. Under the application of mechanical force in the direction perpendicular to the grooves of the corrugated structure, the grooves are deformed, absorbing energy of the impact force and distributing the force over the entire panel. Therefore, the corrugated structure increases the strength of the panel due to the resistance applied to her strength.

When using multi-layer corrugated panels each corrugated layer is located so that its grooves were directed parallel to the grooves of the adjacent layer. Therefore, the application of multi-layer corrugated panel gives you the ability to withstand the forces of compression and such forces, which, under normal circumstances would lead to deformation of the grooves. In this case, the panel is rigid. The product inside the carton, usually made of three or five layers carton, protected from physical shock during transportation. However, despite all these positive qualities such cartons, inner enpowerment will be condensation, causing rusciani product at the time of delivery.

Thus, as shown by these well-known types of packaging industry products fast food, especially for companies involved in the sale of pizza, there is a need for such packaging, which would preserve the heat of the hot products, and, at the same time, would counter the formation of unwanted moisture inside the package, in particular, under the cover.

Known technically advanced solutions designed to force a portion of the steam to get out of this package. One such enhancement was suggested placement of holes and slits on the sides of the package and near its edges. However, in the case of foods such as pizza, heat and steam are allocated from the Central part of the pizza, and the vapor is cooled sufficiently to condense droplets of water with the lid on the product before the air and vapor made these holes. These holes and slots in the package are not located directly on a product that would allow a couple to quickly exit the package. The placement of these holes on a product would allow unauthorized items and dirt to get to the product. In addition, the use of such direct holes passing through the outer side panel, weakens the strength of the panel itself.

The present invention is with the building ventilation panels and ventilation systems, for use as a material to create a closed space, such as packaging boxes, would solve all three problems mentioned above, which cannot be addressed by existing packaging products for fast food. That is, the object of the invention is the provision of sufficient ventilation packaging, to allow the water condensing from the vapor emitted by the product, would have been out on the product in the package, as well as sufficient thermal insulation to the product in the package remained warm.

On the figures as examples of typical types of corrugated cardboard, in Fig. 1A shows a corrugated cardboard, made of two layers - an inner layer 13 and the corrugated layer 19. In Fig. 1B shows tehplastiny corrugated cardboard, with an outer layer 11, a corrugated layer 19, and the inner layer 13. In Fig. 1C shows tehplastiny corrugated cardboard with holes 4 through all layers. This feature is widely used for ventilation of closed volumes.

In Fig. 2A and 2B are top and bottom wall 2 of the ventilation panels for use in the packing box 3, as shown in Fig. 9-13, for carrying hot food. The wall 2 is made of triplestore corrugated cardboard, which consists of three layers: the outer layer 11, the inner layer 13 and the corrugated layer 19. Corrugated layer is located between the outer layer 11 and inner layer 13. The air channel 9 in the wall 2 includes the outer hole 5, the inner hole 7 and the hollow ribs (groove)connecting holes 5, 7, acting as a vent. And oslany channel 9' includes an inner hole 7 and the antinode (hillock) embossing acting as a channel holding the fluid during its movement along and inside of the insulating channel 9'. The outer hole 5 is limited by the hole located in the outer layer 11 forming the outer surface of the cardboard packaging 3, as shown in Fig. 9-13. Similarly, the inner hole 7 is defined by a hole located in the layer defining the inner surface of the box 3, as shown in Fig. 9-13. In Fig. 2A inner bore 7 also passes through the corrugated layer 19, but the outer hole 5 does not pass. As shown in Fig. 2A, holes 5, 7, not coincident and are staggered so that the holes 5, 7 in General do not overlap, although they are adjacent to each other.

Ventilation panel is located in the cover 15 or the top wall of the box 3 (shown in Fig. 9-13). However, the ventilation panel can be located in any wall of the box. Actually, ventilation panel can be located in the bottom wall (bottom) 17, and the cover 15 box 3.

Material for making packaging boxes in this preferred embodiment, application of the invention is mnogoplatnye paper carton having at least one corrugated layer. It is shown in Fig. 2A version of the application has three layers: the corrugated layer 19, one of the ribbings which forms interazioni channel 9 and the insulating channel 9', and two smooth layer, forming respectively the outer layer 11 and inner layer 13 box 3 (shown in Fig. 9-13). You can have more than one pattern for the formation of the ventilation duct 9, which connects the two holes 5, 7, and insulating channel 9', connecting with the hole 7.

Packing box 3 shown in Fig. 9-13, is designed to store hot deliverables during transport, protecting these products from damage from physical impact, the isolation of these products and prevent the formation of moisture condensing on the inner surface of the box from the steam coming out of the product. Such condensate in contact with the product or form of the product would lead to his rusciani. Because the hole 7 of the ventilation panel is located directly above the product in the box 3, the steam coming out of the product, freely passes through the ventilating panel in the atmosphere surrounding the box 3. Steam is not condensed on the surface of the inner layer 13 on the product. Because the holes 5, 7 do not coincide with each other, the foreign body can not fall outside the box 3 directly on the product that could lead to contamination of the product. In addition, since the path of steam from inside the box 3 is not direct, and passes between the layers 11, 13 of the multilayer mother is La, ventilation panel works as a heat exchanger, keeping the heat inside the box 3. This is achieved due to the length of the ventilation duct 9 and the insulating channel 9', which is connected with one of the holes 5, 7. These insulating channels 9' not interconnected openings 5, 7.

The degree of ventilation box 3 can be varied by using different parameters of the components of the ventilation duct 9 and ventilation panels. These parameters include the cross-sectional area of the holes 5, 7; mixing (spacing) between the holes and the length of the ventilation duct 9, the connecting holes 5, 7; the form of the holes, the configuration of the ventilation duct, the orientation of each channel in relation to the rest of the panel material (e.g., type of paper used for the manufacture of multilayer material, the number of riffles, shape and size of the cross-section of riffles used for the formation of channels and the number of ventilation ducts in box 3 (shown in Fig. 9-13).

Similarly, the degree of isolation provided by the wall of the ventilation panels in the box 3 may be varied by using different parameters of the ventilation panel. These settings include: the size and shape of the cross section of the holes 5, 7, shape, configuration and length of each pipe channel 9'; the orientation is each channel in relation to the rest of the panel, the number of insulating channels 9'connecting with the holes 5, 7, the cross-sectional dimension of the pattern used for the formation of each of the insulating channel 9' and the number of ventilation ducts in box 3.

The preferred implementation of the invention is a box of pizza, having a square base and a small depth. The width of this box is many times greater than its height, the distance from the centre of the box to the side walls and ribs too large for effective ventilation was carried out through the ventilation holes located on the sides and edges of the box. As the upper wall (cover) this box can be used for ventilation panel that will allow you to have a vent directly over hot pizza. Of course, the ventilation panel can be used for the manufacture of packaging and many other products, quick delivery, when issues of ventilation and thermal insulation product is essential.

Box 3 can be used in such applications, when necessary ventilation and insulation, for example, for breathing. Such variants are not directly related to food applications include agricultural products, for example, poultry and horticultural products, including flowers, fruits, vegetables and dairy about UKTI. Packing box 3 can be used for many other applications that require ventilation, for example in the architectural products and applications.

The steps of the method for manufacturing the wall of the vent panel shown in Fig. 2A. At the first stage of the method of manufacturing a ventilation panel this panel includes two layers that are not connected with each other, for example anoplasty layer, the outer layer 11 and dwuhmestnyj-mnogoplatnye layer comprising an inner layer 13 and the corrugated layer 19. It should be noted that for manufacturing ventilation panels has one corrugated surface 19, which should be attached to the smooth surface 11. These surfaces belong to adjacent layers in the finished panel. Then in each layer to form two openings 5, 7. The location of these holes is selected such that, with respect to each other by attaching a smooth layer 11 to the surface of the corrugated layer 19 holes will not match and generally do not overlap, and the air channel 9 is formed between the surface of the corrugated layer 19 and a smooth layer 11. It is desirable that the holes 5, 7 were first identified (tagged), and then formed, preferably by way of the perforation. On the second step of the way adjacent layers are fastened to each other, cominformist vent 9 in the vent panel.

In Fig. 3A shows a sectional vent ventilation panels, made of three-layer corrugated cardboard. Line A-A intersects the outer hole 5 in the outer layer. Line B-B through the channels 9, which connects the inner hole 7 with an outer hole 5. Line C-C dissecting the inner hole 7. The line X-X cuts the air channel 9 connecting the inner bore 7 with the second outer hole 5, and the insulating channel connecting hole 7; and the line Y-Y cuts the insulation channels 9 in the panel. Fig. 3B is an enlarged view of the panel between the cross-sections X-X and Y-Y, showing the passage of fluid, as indicated by the arrows, in the configurations inside the panel. Line E-E (as shown in Fig. 3A) through the panel at the trough of the corrugation perpendicular to the cross-sections X-X and Y-Y, and the line F-F through the panel on the crests of the corrugation perpendicular to the cross-sections X-X and Y-Y; and D-D cuts through the panel diagonally. As the line E-E, and line D-D cut through all three layers, inlets and channels.

In Fig. 4A shows a series of sectional views of this panel along lines A-A, B-B, C-C, D-D, E-E and F-F shown in Fig. 3A. These sections show the passage of fluid, as indicated by the arrows, with respect to the channels (9, 9'), as well as to the inner and outer holes 5, 7. These drawings help to illustrate theoretical foundations of the present invention in the issues of ventilation and insulation and, at the same time, opened here a method of manufacturing a ventilation panel.

As for ventilation, the hot fluid passes through the vent panel from the inner bore 7 through the vent channel 9 to the outer hole 5 in the layer 11, where it is released into the atmosphere. The section C-C shows hot the fluid flowing in the air channel 9 and the insulating channel 9' through the bore 7 in the inner layer 13. As shown in Fig. 3B and section B-B in Fig. 4, the fluid passes along the duct 9 formed by the grooves of the corrugated layer 19 and the outer smooth layer 11. As shown in section E-E, fluid passes through the channel 9 to the outer hole 5 formed in the outer layer 11, where it comes out of the vent panel, as shown in section A-A.

In addition, as shown in section E-E, fluid can flow along and inside of the insulating channel 9' from the hole 5 toward the ends of the panel. The end panels can be open, forming an alternative hole 5'.

As shown in section F-F, fluid enters the insulating channel through the opening 7 and flows along and inside of the insulating channel 9', and the fluid is retained within the insulating channel.

As for insulation, hot fluid passes through ventilation the second panel from the inner bore 7 in the insulating channel 9', the external opening 5, as shown in the section view E-E, along and inside the insulating channel 9', as shown in the section view F-F. the Heat from the fluid does not go into the atmosphere and stored in the isolation channels 9' and is absorbed by the material of the panel. If fluid is wet, the condensing it into water droplets occurs in the insulating channel 9'. Since water has a very high specific heat capacity, increasing the amount of water in insulating channel 9' increases the amount of heat that can absorb the box. It should be noted that, persisting inside the insulating channels, the water falls back to the product or other items placed under a ventilation panel.

According to the method of insulating channels function as insulation of hot fluid on the inner side of the panel from more than the cold fluid on the other side of the panel. When the panel will have their open ends of riffles in the ends of the panel, you can close them to create a corked hole 5, and the channel between the closed holes and corresponding holes 5, 7 becomes insulating channel 9'. Thus, the condensate formed in the insulating channel 9', remains in this channel. If the panel made box for food storage, the condensate does not fall on this food. Those who lo is stored inside the box, and loss of water vapor is nil or negligible.

The insulating channels 9' can be performed as shown in Fig. 3A and 3B, between the inner layer 13 under the peaks of the corrugated layer 19 so that fluid is routed directly from the interior of the hole 7 in the direction of the corked hole 5 or to another internal opening, as shown in figa. In another embodiment, it may be directed from the inner holes 7 along and inside of the insulating channel 9' toward the clogged hole 5", the distance from the outer holes 5 along the channel formed by the outer layer and the groove of the corrugated layer. Of course, if the outer hole 5 passes through the corrugated layer instead of the inner hole 7, the situation will be reversed: channel 9 connecting the inner bore 7 with the outer hole 5 will be then between the peaks of the corrugated layer 19 and the adjacent surface of the inner layer 13.

The preferred method of manufacturing a ventilation panel includes technology perforation of the split layer. In this technology, the split layer is perforated layers panel separately before these layers are fastened together, forming a panel, and it is done in such a way that the holes of adjacent layers do not overlap with each other. However, the corrugation between the layers and the inside of the layers panel, create indirect channels between the holes, located in the inner and the outer layers. Of course, some channels in the finished panels are connected with only one of these holes. Thus, the patterns produced by this technology have both insulating and ventilating properties.

Depending on the application wall 2, the position of the holes 5, 7 can either be changed in the Central region, or the holes may be distributed throughout the panel, which leads to the formation of the panel with any pattern or random port configuration.

On figa, B and C shows how you can create a simple vent in the wall or ventilation panels made from dvuxmestnogo corrugated cardboard. In Fig. 5A shows a wall having an inner layer 13 with two sections, each of which functions as the inner hole 7, and the corrugated layer 19, in which the open ends of each corrugation is working as the outer hole. In Fig. 5B presents the opposite view of Fig. 5A. In Fig. 5C shows an alternative implementation of ventilation in dvuhmestnoj wall, where only in corrugated layer 19 holes cut. In this embodiment, an open inner end of each corrugation performs the function of the inner bore 7, and each open outer end of each corrugation performs the function of the outer holes 5. In Fig. 5D showing the N. another version of the application, it is shown in Fig. 5C. In this embodiment, the inner layer has two openings in the form of stripes, which is the inner holes. In Fig. 5E(1) and 5E(2) as the next version of the application shows a wall made of dvuxmestnogo corrugated cardboard, with the air channel created by nonlinear perforation, thus achieving the formation of the patterned surface. This dvojplotna corrugated panel shown in Fig. 5D and 5E may also be used as a sleeping pad with ventilation properties for items in need of ventilation, which is placed, for example, under the food to prevent it from rasisanie.

In Fig. 6A and 6B illustrates the steps comprising the method of manufacturing a ventilation panel. In Fig. 6A schematically shows how a single smooth layer of the outer layer 11, for example, sandwich panels, perforated separately from the inner layer consisting of a single smooth layer 13 and the corrugated layer 19. Perforation of the inner layer carried out in one step by joint perforation smooth layer 13 and the corrugated layer 19. In Fig. 6B shows how two layers - anoplasty 11 and the inner corrugated layer 19, which forms together with the second single smooth layer of the outer layer 13, are assembled together to form the wall of the ventilating duct and, with ventilation and insulation channels.

In Fig. 7A and 7B shows the various combinations and placement mnogoletnego layer, which includes more than three layers, and possibly more than two layers in the wall of corrugated Board having at least one ventilation channel. These figures also depict possible variants of the layers panel, with emphasis on how to change the orientation of the channel in relation to the rest of the panel.

In Fig. 7C, D, E and F shows a cross section of possible configurations of channel 9 in the vent panel, consisting of three or more layers. In Fig. 7C shows patipata, but two-layer ventilation panel. There is only one channel 9 connecting the two openings 5, 7. In Fig. 7D shows patipata three-layer ventilation panel. It has two connecting channel 9, each channel between different surfaces of the layers in the ventilation panel. In Fig. 7E shows semiplena two-layer ventilation panel. It has only one connecting channel. In Fig. 7F shows semiplena four ventilation panel with three channels connecting holes 5, 7.

If you use more than two layers, each of which may consist of more than one layer, the holes in the layers one layer coincide with each other. Holes adjacent layers yavlyaetsyaprostota and are adjacent to each other, but not overlapping each other. This enables the formation of channel 9 between adjacent layers. If there are two or more channels, layers, located between the inner and outer layers are called intermediate.

In Fig. 8A shows one side, and Fig. 8B is another side of the row of ventilation channels in the corrugated vent panel, where the panel is a flat blank for making the box. Of the box separated by dashed lines. This blank can be folded on the dotted lines for the formation of the box.

In Fig. 9A-9E shows the carton 3, having at least one means of ventilation 1 and the flat blank template 20 for this box. In Fig. 9A-9E presents the stages of manufacture of the box 3 and the workpiece template 20 from triplestore cardboard. This method is based on the attachment layer 19 having a corrugated surface 21, to the other layer 11, which may be corrugated, but in the preferred embodiment, is smooth.

In Fig. 9A dwuhmestnyj layer 25 having a smooth inner layer 20 and the corrugated layer 21, clipped and has channels that define the bore 7. In Fig. 9B shows another side of this layer, flat and smooth surface dvuxmestnogo layer 25. Anoplasty outer layer 27 are cut in the same size as duplanty the layer 25. Channels that define the outer hole 5, carved from anoplostoma the outer layer. These openings 5 are displaced relative to the inner bore 7. Then anoplasty outer layer 11 is fastened to dvuhestny layer 25, for example anoplasty outer layer is glued to the corrugated surface dvuxmestnogo layer. Thus, holes 5, 7 are close to each other, but without overlapping. After folding template 20 and the receiving box 3 vents are placed in the cover 15, as shown in Fig. 9E.

This method can be used not only for receiving openings 5, 7, having a round cross section, but, as shown in Fig. 10A-E and 11A-E, these openings may have a triangular cross-section or other shape. These figures also shows that the holes 5, 7 can be placed at the base of the box 3, and the cap, as shown in Fig. 10E.

In Fig. 10A-C and 11A-C show the stages of fabrication of two types of boxes 3 of the template 20. Each blank is made of dvuxmestnogo layer 25 having a corrugated surface 21, as shown in Fig. 10A and B, and anoplostoma layer 27 with a smooth surface 23, as shown in Fig. 10C and 11C. Holes 5, 7 first, any punching in layers 27 and 25, respectively. The smooth surface 23 and the corrugated surface 21 is then fastened together, clicks the Zuya the workpiece 20. After that the block can make the box, as shown in Fig. 10E.

In accordance with Fig. 10D, 10E, 11D and 11E, each of which shows the box 3 with ventilation channels in the cover 15 and bottom 17, this box can be modified to improve retention pizza by placing on the base 17 of ventilation Mat (not shown)made of a ventilation panel with air channel. When the Mat is placed on the top of the base 17, which is placed vents, circulation of the fluid inside the box 3 is improved. Therefore, more vapor from the product being released into the atmosphere surrounding box 3, further reducing the amount of condensation falling on the product.

If you raise the bottom of the box through various built-in methods, couples will also be able to leave the bottom. One such method is a folding prop, which can be attached to the box or attached to it during its transportation. When a box is placed on any surface, it can stand on this surface through the support. Thus, the box is lifted from the surface, allowing fluid to pass through the vent in the vent panel, available in the bottom of the box, through the ventilation box h is cut the bottom. Of course, such support can have one or more legs.

When changing the preferred option of manufacturing the panel corrugation corrugated surface may have not necessarily sinusoidal cross-section, and any other. Therefore, the layer may consist of riffles, having a repetitive series of cross sections of regular or irregular. The type, combination and layers of paper may be varied to achieve different aesthetic and functional purposes (e.g., degree of ventilation). These modifications will depend on the final destination of the package 3, its design and the look you want.

In the following embodiment, the ventilation channels can be placed in the walls of the box 3 is not only between the outer layer 11 and inner layer 13 box 3, but also in the walls of the partitions dividing the box into many branches (not shown).

In the next version of the insulating channel 9' can be made where the ribs connect the inner hole 7 with an outer hole 5. Such a channel 9' is created by flattening at least a part of the pattern (not shown). This is an acceptable method of forming an insulating channel 9' and 5".

Panels intended for the manufacture of boxes, such as are described in the main embodiment, can be made of various materials, not only from cardboard; with the Yes includes, not limited to, various types of white and wrapping paper (laminated paper, duplex cardboard, coated paper, parchment paper, and so on), various types of plastics such as high density polyethylene, low density polyethylene, polycarbonates), PVC, PET, glass fiber, fiberglass, rubber, wood, chipboard, plywood, veneer, sheet metal, including galvanized iron or aluminum, alloys, ceramics, cement, clay, soil, leaves, asbestos, wire or wire mesh, woven and nonwoven fibers and combinations of these materials. Layers ventilation panels may consist of layers of one material or different materials in different combinations.

In the following embodiment, the channels can be formed by bonding the corrugated layers in between. Their ribs need not be parallel or perpendicular to each other, but such variants are preferred. The width and shape of the riffles should not be necessarily identical, however, this option is also preferred.

In the following embodiment, the ventilation panel only provides insulation, because it is formed only one of the holes 5, 7. Channel 9 is connected with the created hole that allows the panel to work as an insulator, but not to perform the function of ventilation.

In the next version the application of the Oia box, manufactured in accordance with the invention, shown in Fig. 12. In many respects it is similar to the box shown in Fig. 9, 10 and 11, except for the outer holes 5 of the ventilation channels in the form of letters.

Any of the boxes 10, 11 and 12 can be modified to improve the storage of hot food by placing mnogoplodnoy (for example, dvuhmestnoj) corrugated ventilation panels above the internal opening 7 in the lower part of the inner surface of the box, as shown in Fig. 13. Such a seal with the air channel, improves circulation of the fluid inside the box, allowing the heat to stay inside the box, and a couple of water and go outside.

The Mat is a type of seal or packing detail. Such seals for boxes also include dividers or partitions for offices.
