SELF-STANDING INSULATING SPACE-EFFICIENT PACKAGING ASSEMBLY FOR FOOD AND BEVERAGES

Description

[0001] The present invention concerns a self-standing, insulating space-efficient packaging assembly containing a product, which can be reconstituted with water and / or heated in a microwave oven.

[0002] It is known according to US Patent No. 3'542'566 to have a collapsible container package for concentrate. With this solution, the user has to tear the upper part of the package to open it and also the lower part of the package to allow the inner pouch to expand its volume. This gives a package with restricted initial volume and heat insulation, which is not self-standing and not easy to open.

[0003] The FR patent No. 2'207'066 discloses a water and airtight sachet for conditioning liquid products in particular, of the type made of a film of flexible material and essentially comprising a flattened sheath making up at least two lateral walls joined at their lower extremity to form the base of the said sachet, while each of the lateral walls of this sachet comprises a longitudinal strengthening rod or strip, characterized in that this strip is shorter than the closed sachet, its lower edge being on the one hand in contact with the corresponding wall and on the other hand situated at a certain distance from the base of the said sachet. The stiffening of the walls has the effect, that the packaging can be self standing.

[0004] The GB patent No. 1'536'110 concerns a rigid pouch usable as a cup and a method of producing the same, wherein outer rigid material is lined with inner flexible material, the sheet obtained thereof is center-folded and its opposed parts joined together to form a rigid pouch which, when unfolded, is claimed to turn into a package that can be used as a cup. This gives a package without bending lines on the rigid part, which is difficult to manufacture, fill, open, fold, unfold and seal and which is not locked in unfolded position.

[0005] The present invention concerns a packaging assembly, whose advantages for the user compared to prior art are easier opening, better self-standing when unfolded, easier handling and less space utilisation in carrying, storage and disposal. The advantage of the present invention for the food manufacturer compared to prior art is less space utilisation in transport of packaging materials or pre-formed packaging assembly from the supplier to the filling location

[0006] The present invention concerns a packaging assembly comprising

• two separate opposite outer panels composed of rigid material, each said outer panel comprising two side parts with their respective side edges, a middle part, an upper part with its respective upper edge and a lower part with its respective lower edge, wherein each said side part comprises a least one bending line and each middle part comprises at least one bending line and
• an inner pouch disposed inside said two outer panels, said inner pouch comprising two opposite walls, each said wall comprising a lower, an upper and two side parts, wherein said two walls are bonded together and also with said two outer panels in a way that the packaging assembly can be unfolded and/or erected by pressing said outer panels together on their side edges and wherein the upper parts of the walls of said inner pouch are placed higher than the opposite upper edge of said outer panels and the lower parts of the walls of said inner pouch are placed higher than the opposite lower edge of said outer panels.

[0007] It is preferable according to the invention to have one bending line in each side part and one bending line in each middle part.

[0008] The packaging assembly under the present invention provides easy opening, folding, unfolding, locking in unfolded position, self-standing and heat insulation.

[0009] According to the invention, easy opening of said packaging assembly is provided by the material of the inner pouch and/or by additional means on the material or/and on seals of said inner pouch.

[0010] According to the invention, folding and unfolding of said packaging assembly is provided by the bending lines on the outer panels and by the bonding areas between the outer panels and the walls of the inner pouch.

[0011] According to the invention, locking of said packaging assembly in unfolded and erected position is provided by means on the lower parts of the outer panels.

[0012] According to the invention, self-standing of said packaging assembly in unfolded position is provided by the lower edges of the outer panels.

[0013] According to the invention, heat insulation of said packaging assembly is provided by the side parts of the outer panels and by the middle bending line on the middle part of the outer panels. Therefore, in the case of reconstitution of a product with hot water or/and microwave heating it is possible to hold the packaging assembly vertically on its side edges without burning hands/fingers.

[0014] According to the invention, it is possible that the packaging assembly be either empty or filled. In the case of an empty packaging assembly, the inner pouch is open.

[0015] In the case of a filled packaging assembly, the product inside the inner pouch can be a dry, a pasty or a liquid material with or without pieces and the inner pouch is closed.

[0016] According to the invention, the outer panels are made from solid or corrugated board or a combination thereof having a grammage comprised between 100 and 1000 g/m2.

[0017] According to the invention, the inner pouch is made from a single-layer or multiple-layer material, wherein the layer or layers is/are taken in the group comprising Aluminium, Paper, Polypropylen, Polyethylen, Polyester, Polyamide, Ethylen vinyl alcohol comprising any coatings, adhesives and additives, the total thickness of the inner pouch being comprised between 10 and 1000 microns.

[0018] According to the invention, the inner pouch and the outer panels can be printed or unprinted.

[0019] According to the invention, it is possible to cover the outer panels with or place the panels inside an additional layer or layers of insulating material e.g. polystyrene foam, with or without bonding it with said outer panels. The additional insulating material is not critical as heat insulation is already provided by the material and geometry of the outer panels.

[0020] According to the invention, the walls of the inner pouch are bonded with the outer panels with adhesives or by seaming. This means that the outer panels are not bonded together directly and the assembly is maintained together by seaming or gluing between the inner pouch and the outer panels and also by the side seals on the walls of said inner pouch.

[0021] According to the invention, it is possible that the inner pouch containing a product be formed and sealed in closed position in several ways

[0022] One solution is that the upper parts of the walls of the inner pouch are bonded together forming a top seal. In this case, it is a classical way of proceeding and the user tears the bonded upper parts of said inner pouch on one side to open the inner pouch. The user has then to press the side edges of the outer panels together, therefore opening completely said inner pouch, so that hot water can be poured into the inner pouch to reconstitute the product. The easy opening in this case is provided by the material of the inner pouch which is easy to tear e.g. comprising paper, mechanical or laser perforation, easy-tear sealant layer e.g. easy-tear polypropylene or combination thereof.

[0023] The second solution is that the upper parts of the walls of the inner pouch are bonded together forming a top seal, whereas one or two side seals on the walls of the inner pouch present a notch or a slit for starting the tearing. It is a solution that is similar to the 1^st one, the only difference is the notch or slit so that the user has an even easier way to open the inner pouch, the way of proceeding afterwards being the same as for the 1^st solution.

[0024] The third solution is that the upper parts of the walls of the inner pouch are bonded together forming a top seal, whereas said upper parts contain an easy-peel material e.g. easy-peel polypropylene or comprise a coating or adhesive that allows said upper parts to open from the bonded position when the side edges of the outer panels are pressed together. This means that the user has nothing to tear, he has only to press the side edges of the outer panels together, so that there is a separation of the bonded upper parts of the walls of the inner pouch. This solution combines easy opening and no torn piece like in solutions 1-2 to be disposed of.

[0025] The fourth solution is that the upper parts of the walls of the inner pouch are bonded together forming a top seal, whereas said upper parts contain an easy-peel material e.g. easy-peel polypropylene or comprise a coating or adhesive that allows said upper parts to open from the bonded position under pressure and/or temperature increase inside the inner pouch. For this solution, the most known procedure is to place the closed packaging assembly containing a product upwright into a microwave device. The user does not need to open the packaging assembly anymore after microwaving as it opens and erects by itself in the microwave device. This solution combines self-opening and no torn piece like in solutions 1-2 to be disposed of.

[0026] According to a further feature of the invention, the packaging assembly comprises means at the lower parts of the rigid panels for locking the unfolded and erected packaging assembly in that position. This prevents folding the packaging assembly back when filled with reconstituted product and when pressing the outer panels by mistake, and, consequently, helps prevent the product from pouring out when not desired.

[0027] According to the invention, all kinds of technically feasible shapes are possible for the packaging assembly including the inner pouch, the outer panels, the means of locking said packaging assembly in unfolded and erected position, the seals on the inner pouch and the bonding areas between the inner pouch and the outer panels.

[0028] Finally, the present invention concerns a method of producing the packaging assembly as described before, wherein
