Semi-rigid shipping container with opening-resealing closure

Cross reference to related requests

This application claims the priority of the provisional US application No. 61 / 946.654, filed February 28, 2014, entitled "Semi-Rigid Shipping Container with Peel-Reseal Closure."

Technical field

The present disclosure relates to packages and, more particularly, to a sustainable packaging system that includes a cardboard container and a sealed liner assembly for shipping liquid, viscous or particulate products.

Background

Substantially rigid plastic packages with replaceable covers, for example, cube-type packages, are commonly used to package and ship selected liquids and viscous materials by the nature of food and food preparation materials, cosmetic preparations, detergents and the like (see, for example, WO 2011062969 A2). Such packages are robust, generally having a wall thickness in the range of about 1,905 mm to about 2,286 mm, and have a large mouth that makes them suitable for storing and dispensing a variety of viscous liquids, for example, syrups, mustard and preparations Cosmetics A typical 20 liter empty bucket can weigh approximately 1,021 kg.

Another way of sending liquid products is the "bag and box" set in which a bag, made of a flexible plastic film of one or two layers and provided with an accessory for the discharge of the contents of the bag, is stored in a box Made of corrugated cardboard. This type of packaging system is very suitable for fluid liquids, such as vinegar, wine, detergents and the like. However, it is not suitable for viscous materials for several reasons. For example, it is difficult to remove the entire contents of the bag, due to the inability to extract the residual contents of the bag. In addition, in the case of a material consisting of several ingredients that tend to separate from each other while standing, it is not possible to introduce a shaking implement into the bag in order to mix the contents to obtain a homogeneous material.

Other limitations derive from the plastic recycling requirements and food packaging regulations. Environmental regulations require that packages with a volume of 18.93 l or less be made of a recyclable material. In addition, government regulations require that plastic food packaging be made of a virgin plastic material. Substantially rigid plastic packages comprise a relatively large amount of plastic compared to the flexible bags used in the "bag and box" packaging system, which increases the amount of plastic to be disposed of or recycled. The manufacture of such virgin plastic packaging is expensive and, therefore, discourages its use to contain food. The "bag and box" system uses less plastic, but the bags are not as robust as substantially hard packaging and cannot be used where it is essential to access all the contents or where you want to mix the contents in situ.

Summary

The present disclosure relates to a packaging system and more particularly to a sustainable packaging system that includes a cardboard container and a sealed liner assembly for shipping liquid, viscous or particulate products. The present invention as defined in claim 1, relates to a packaging assembly for containing liquids, viscous material or particulate material. The packaging set includes a self-supporting plastic liner to be inserted into a cardboard container. The lining has a closed bottom end that is a bottom wall formed integrally with the side wall, and an open top end that has a flange that projects outwardly.

The packaging assembly further comprises an opening-resealing capping assembly that includes first and second layers and a capping material as specified in claim 1.

Detailed description

The present disclosure relates to a new and advantageous sustainable packaging system that can be used to ship liquid or viscous products or particulate matter. Traditionally, liquid products, for example, thick viscous products, such as thick paints and inks, cosmetic compounds, glazes and food fillers, wall putty, thick roof sealants, powders and flakes, or similar products have been packaged for shipping or sale in buckets or buckets made of materials such as steel or thick plastic. A single traditional 20-liter bucket of this type can weigh approximately 1,021 kg empty, which adds a considerable amount of weight to a product shipment. Buckets or buckets are also usually cylindrical in shape, which makes them inefficient for palletizing or shipping because there is a substantial amount of unused space between one cube and the next. In addition, due to the rigidity of the cubes, they can occupy a significant amount of space after use, but before disposal. In addition, buckets can be difficult or expensive to dispose of or recycle.

The packaging system of the present disclosure generally includes an outer container or cardboard box and an inner liner. The inner liner can be sealed after filling the liner with the product. A coating cover may be placed on the sealed coating and / or a cardboard container cover may be placed on the cardboard container containing the sealed and filled inner coating. The square or rectangular shape of the packaging system allows a box to be placed directly next to and / or on another box, effectively maximizing the amount of product that can be stored or shipped in a limited space. For shipping purposes, the more units that can be loaded by truck, the costs of inbound transportation are reduced.

In addition to the advantageous form of the packaging system of the present disclosure, a single empty packaging system, in one embodiment, can weigh approximately 151 g, compared to approximately 1,021 kg of a traditional bucket of similar volume. This difference in weight results in a ratio of 7 A to 1 weight savings for the packaging system of the present disclosure on the traditional bucket. The lighter packaging system by weight of the present disclosure may be easier to move, less expensive to ship, requires less production energy and is easier to recycle and easier to store before recycling than traditional buckets.

Figure 1A shows a packaging system 100 according to the prior art. The packaging system 100 may include a cardboard container 102, an optional mat or liner 180, a plastic liner 120, a capping material 140 that can be sealed to the plastic liner 120 and a plastic lid 150. The cardboard container 102 can be a conventional cardboard container constructed of, for example, corrugated cardboard and a rigid cardboard that can be 100% recyclable, although other lightweight and / or recyclable materials can be used for the container. The cardboard container 102 may have a generally square or rectangular cross-sectional shape. The cardboard container 102 may have a side wall that includes four square or rectangular panels 104, a bottom wall 106, and in some embodiments, an open top without any flap to be closed and / or sealed.

In one example, the coating 120 may be made of plastic and be relatively semi-rigid and thin, more or less in the range of about 0.203 mm to about 0.762 mm thick. However, it is warned that the thickness of the coating could vary and could be outside the range of about 0.203 mm to about 0.762 mm, and in some examples, it may depend on the desired use or application of the coating 120. The coating 120 can be manufactured by any means known in the art, such as, among others, vacuum forming, blow molding or injection molding. The coating 120 may be made, for example, of a 100% recyclable material, such as, among others, high density polyethylene (HDPE) or linear low density polyethylene (PELBD). Unlike the plastic film bags used in the bag and box assembly described above, the liner 120 can be self-supporting. However, the relative thinness of the liner can make the liner easily foldable, which can significantly reduce the volume and the cost of disposal compared to traditional buckets. Due to the thinness and / or the weight of the cardboard container 102 and / or of the coating 120, more liners can be sent by truck, and in some cases many more, than traditional rigid cubes. For example, siding can be shipped in shipments of approximately 28,000 units compared to only 3,412 traditional buckets per truck. The increase in the number of coatings that can be sent in a single truck load can advantageously result in fewer truck loads needed to ship the packaging system of the present disclosure and, therefore, less greenhouse gases are produced.

The liner 120 may have a cross-sectional shape similar to cardboard container 102, for example, a square or rectangular cross-sectional shape. Alternatively, the coating may have any other shape, such as, among others, an oval or round cylindrical shape, as described in more detail below. In any case, the liner 120 can be sized to fit inside the cardboard container 102. In the illustrated embodiment, the liner 120 has a substantially square cross-sectional configuration and comprises a bottom wall 124 and a side wall that includes four sides or panels 122 that may have a shape substantially similar to panels 104 of the cardboard container 102. When the plastic liner 120 is inside the cardboard container 102, the plastic liner 120 may rest on, and be supported by, the bottom wall 106 of the cardboard container 102. The panels 122 can usually be slightly smaller than the panels 104 of the cardboard container to allow the liner 120 to fit inside the cardboard container 102. In one example, the panels 122 of the liner Plastic 120 may be substantially close to the side walls 104 of the cardboard container 102 when the liner is arranged in the cardboard box. The upper end of the liner 120 may be open, but may be formed with a flange 126. As best seen in Figure 2, the flange 126 of the liner 120 may include a radially extending flange portion 210 and a skirt portion 212 dependent. The flange 126 may extend completely around the perimeter of the liner 120, being an integral extension of the upper end of the panels 122. In another example, the edge may extend partially around the perimeter of the liner. When the liner 120 is disposed in the cardboard container, the upper edge of the side wall 104 of the cardboard container can be placed below the flange 126 of the liner 120 as can be seen in Figure 2, with the upper edge of the side wall 104 between the side wall of the liner 120 and the skirt portion 212.

As indicated above, the coating may have any other suitable form. For example, as shown in Figure 1B, a liner 152 may have a substantially circular cross-sectional shape, sized to fit inside the cardboard container 102. The upper part of the liner 152, in one embodiment, may contain a flange 154 square or rectangular, so that the flange can extend completely around the perimeter of the liner 152, being an integral extension of the upper end of the liner. In a further example, the flange may extend partially around the perimeter of the liner.

In another example of a liner having a substantially circular cross-sectional shape, sized to fit inside the cardboard container 102, as shown in Figure 1C, a liner 162 can be designed to generally fit inside the cardboard container 102. The Cardboard container 102 may include additional inner side panels 164. The inner side panels 164 may extend substantially around the entire inner perimeter of the side wall panels 104, or they may extend around only a portion of the inner perimeter of the side wall panels 104. Although not necessary, the inner side panels 164, in some embodiments, may be slightly taller than the outer panels 104. The liner 162 may contain a square or rectangular flange 166, which may extend totally or partially around the perimeter of the liner, and can be supported on an upper edge of the inner side panels 164. The liner 162 may be placed with the flange 166 on an upper edge of the inner side panels 164 completely within the side wall panels 104 of the cardboard container or in addition be on an upper edge of the side wall panels 104.

In another example more than a liner having a substantially circular cross-sectional shape, sized to fit inside the cardboard container 102, as shown in Figure 1D, a liner 172 can be designed to generally fit inside the cardboard container 102. The cardboard container 102 may include additional inner side panels 174, which provide an octagonal internal geometry or other suitable polygonal geometry. The inner side panels 174 may extend substantially around the entire inner perimeter of the side wall panels 104, or they may extend around only a portion of the inner perimeter of the side wall panels 104, as but not limited to, extend only to through the corners of the side wall panel panels 104 of the cardboard container. Although not necessary, the inner side panels 174, in some embodiments, may be slightly taller than the outer panels 104. The liner 172 may have a flange 175 of generally smaller polygonal shape or the flange may be a flange shaped substantially circular, which can extend totally or partially around the perimeter of the lining. The octagonal inner side panels 174 at the corners of the side wall panel panels 104 may include cut-off excisions for the liner to pass through, thus supporting the lining by means of the interface between the cut-off excisions of the inner side panels of the corners and the flange 176 with a substantially circular shape.

In another example, more than one liner having a substantially circular cross-sectional shape, sized to fit inside the cardboard container 102, as shown in Figure 1E, a liner 182 can be designed to generally fit inside the cardboard container 102. The cardboard container 102 may include additional internal side mats 184, which may adhere to the side wall panels 104 of the cardboard container, for example with adhesive. The inner side mats 184 do not have to be designed to extend along the full height of the side wall panels 104 of the cardboard container, but can be designed to be significantly shorter. The inner side mats 184 can extend substantially around the entire inner perimeter of the side wall panels 104, or they can extend around only a portion of the inner perimeter of the side wall panels 104. The lining 182 may contain a flange 186 of a square or rectangular shape, which may extend totally or partially around the perimeter of the lining, and may rest on an upper edge of the inner side mats 184. The lining 182 may be placed with the flange 186 on an upper edge of the inner side mats 184 completely inside the side wall panels 104 of the cardboard container or also be on an upper edge of the side wall panels 104.

In yet another example, as shown in Figure 1F, a liner 232 may have a substantially oval cross-sectional shape, sized to fit inside the cardboard container 102. The upper part of the liner 232, in one embodiment, may contain a square or rectangular flange 234, so that the flange can extend completely around the perimeter of the liner 232, being an integral extension of the upper end of the liner. In a further embodiment, the flange may extend partially around the perimeter of the liner.

In another example of a liner having a substantially oval cross-sectional shape, sized to fit inside the cardboard container 102, as shown in Figure 1G, a liner 242 can be designed to generally fit inside the cardboard container 102. The Cardboard container 102 may include additional inner side panels 244. The inner side panels 164 may extend substantially around the entire inner perimeter of the side wall panels 104, or they may extend around only a portion of the inner perimeter of the side wall panels 104. Although not necessary, the inner side panels 244, in some examples, may be slightly taller than the outer panels 104. The liner 242 may contain a square or rectangular flange 246, which may extend totally or partially around the perimeter of the liner, and can be supported on an upper edge of the inner side panels 244. The liner 242 can be placed with the flange 246 on an upper edge of the inner side panels 244 completely within the side wall panels 104 of the cardboard container or also be on an upper edge of the side wall panels 104.

In another example more than a liner having a substantially oval cross-sectional shape, sized to fit inside the cardboard container 102, as shown in Figure 1H, a liner 252 can be designed to generally fit inside the cardboard container 102. The cardboard container 102 may include additional inner side panels 254, which provide an octagonal internal geometry or other suitable polygonal geometry. The inner side panels 254 may extend substantially around the entire inner perimeter of the side wall panels 104, or they may extend around only a portion of the inner perimeter of the side wall panels 104, as but not limited to, extend only to through the corners of the side wall panel panels 104 of the cardboard container. Although not necessary, the inner side panels 254, in some embodiments, may be slightly taller than the outer panels 104. The liner 252 may have a flange 256 of generally smaller polygonal shape, or the flange may be a flange of substantially oval shape, which can extend totally or partially around the perimeter of the lining. The octagonal inner side panels 254 at the corners of the side wall panel panels 104 may include cutouts for the liner to pass through, thus supporting the liner by means of the interface between the cuts of the inner side panels of the corners and flange 256 substantially oval.

In another example more than a liner having a substantially oval cross-sectional shape, sized to fit inside the cardboard container 102, as shown in Figure 1I, a liner 262 can be designed to generally fit inside the cardboard container 102. The cardboard container 102 may include additional internal side mats 264, which may adhere to the side wall panels 104 of the cardboard container. The inner side mats 264 need not be designed to extend the full height of the side wall panels 104 of the cardboard container, but can be designed to be significantly shorter. The inner side mats 264 can extend substantially around the entire inner perimeter of the side wall panels 104 or can extend around only a portion of the inner perimeter of the side wall panels 104. The lining 262 may contain a flange 266 of a square or rectangular shape, which may extend totally or partially around the perimeter of the lining, and may rest on an upper edge of the inner side mats 264. The lining 262 may be placed with the edge 266 on an upper edge of the inner side mats 264 completely within the side wall panels 104 of the cardboard container or further be over an upper edge of the side wall panels 104.

Other options for supporting substantially circular or oval shaped liners within a box having a square or rectangular cross-sectional shape are within the scope of the present disclosure. Although the features can generally be described herein with reference to the coating 120, it is understood that such features can also be applied to other coating examples, such as those described above.

A capping material 140 can be sealed over the top of the liner 120 to retain the product within the liner 120. The capping material 140 can be advantageous when the contents of the liner must be protected from moisture, air, bacteria or others. materials that can have a detrimental effect on the content. The capping material 140 may be, for example, a thin-film plastic material or a thin metal foil that can be sealed to the liner 120 by any means, for example, by heat-sealing the capping material 140 to the liner 120. In other examples, The capping material may be made of any suitable material to seal the lining of one or more moisture, air, bacteria or other materials that may have a detrimental effect on the content. In some embodiments, the capping material may be made of a 100% recyclable material. The cover material can also be secured to the coating by means of an adhesive or other sealing methods currently known or developed in the future. As can be seen in FIG. 2, the capping material 140 can cover the entire open area 214 of the liner 120 and can be sealed to the radially extending flange 210 that runs along the perimeter of the side wall 122 of the liner 120.

In some examples, a packaging system may not contain a capping material, but it may contain a plastic lid, a cardboard container lid, or both a plastic lid and a cardboard container lid, as will be described in detail. then.

The packaging system 100 illustrated in Figure 1A shows a plastic lid 150 that can fit both the liner 120 and the cardboard container 104 when the liner is placed inside the cardboard container. Figure 2 shows the plastic lid 150 secured on the flange 126 of the liner 120. The plastic lid 150 may be made of an elastic plastic or other suitable elastic material and have a shape that generally fits into the opening of the liner 120. By way of example, but not limitation, the plastic cover may be made of the same material as the lining or of some other material, and may have the same or different thickness. The plastic lid 150 may include a flange 216 that is designed to substantially engage or, if not, engage in a detachable manner with the flange 126 of the liner 120. As best seen in Figure 2, the plastic lid 150 has a portion central 218 that can cover the covering material 140 of the liner 120. In alternative examples, the central portion 218 of the lid 150 or portions thereof can be removed. The flange 216 of the plastic lid 150 may include a skirt portion 220 that fits in, and in some cases conforms to, the skirt portion 212 of the liner 120. The interlaced skirt portions 212, 220 of the liner 120 and of The plastic lid 150 may be of any configuration that allows a generally perfect fit between the skirt portion 212 of the liner and the skirt portion 220 of the plastic lid. In the embodiment shown in Figure 2, the skirt portions 212, 220 generally have a C-shape, bulging outward, away from the boxing system, at the top of the skirt portion, then bending inward toward the system encased, and subsequently bends out again forming a lip 213, 222 around the perimeter of the liner and the plastic lid. However, it is noted that any suitable interlocking or coupling mechanism or means can be used to uncoupleably attach the lid 150 to the liner 120.

The plastic lid 150 can be attached to the liner 120 by pressing it down onto the flange 126 of the liner 120. The downward pressure action can result in the lower end of the skirt portion 220 of the plastic lid 150 being forced into It was at a sufficient distance to fit the skirt portion 212 of the liner 120 under pressure. The inherent resilience of the plastic from which the plastic lid 150 is made can cause its flange 216 to engage, or to engage firmly with the flange 126 of the liner as shown in Figure 2, unlockingly blocking the plastic lid 150 with the liner 120. The plastic lid 150 can be removed by forcing it upwardly away from the liner 120, with the skirt portion 220 of the lid plastic bending out to release the plastic cover from the liner. Figure 3 shows a cardboard container 102 with a plastic lid 150 secured to a liner that is inside the cardboard container 102.

In another example, the packaging system may have a cardboard container lid in addition to or instead of a plastic lid. Figure 4A shows a cross section of an embodiment that includes a plastic lid 150 and a cardboard container lid 400. As shown in Figure 4B, the cardboard container lid 400 may be made, for example, of cardboard corrugated and a rigid cardboard that can be 100% recyclable. By way of example, but not limitation, the lid of the cardboard container 400 may be made of the same material as the cardboard container 102 or of some other material, and may have the same or different thickness. The lid of the cardboard container 400 may be made to generally fit over the cardboard container 102 and the liner 120. Figure 4b illustrates a lid of the cardboard container 400 with an inner portion 402 and four side walls 404. The lid of the container cardboard 400 may have substantially the same shaped cross section as the cardboard container it will cover, except that the cardboard container lid may be slightly larger than the cardboard container, so that the cardboard container lid can fit, and in some cases safely, in the cardboard container 102 and in the liner 120. Therefore, like the box itself, the lid of the cardboard container can be square or rectangular.

In a further example, a lid of the cardboard container 400 may generally be integral with the cardboard container 102 and at least partially detachable from the cardboard container along a corrugated tear strip, pull strip or perforation strip. Although not necessary, this type of cardboard container lid can preferably be used with embodiments of coatings that completely fit within the side wall panels 104 of the cardboard container. The tear strip can be removed (or the pull strip can be pulled, or the perforated line can be separated) to allow the lid of the cardboard container 400 to be separated at least partially from the cardboard container 102. In some examples, The tear strip can extend completely around the cardboard container 102, to allow the lid of the cardboard container 400 to be completely removed from the cardboard container to expose the inner liner. In other embodiments, the tear strip can extend only partially, for example, around three sides of the cardboard container, to allow the lid of the cardboard container 400 to be partially removed from the cardboard container to expose the inner lining. In any of the embodiments, the lid of the cardboard container 400 may be reusable to reseal or re-cover the cardboard container once it is no longer desired to access the inner liner. In further embodiments, the tear strip may be located in any suitable position to allow a portion of the cardboard container to open to access the inner liner.

In yet another example, the lid of the cardboard container may generally be integral with the cardboard container 102 and comprise one or more flaps, which can be folded over the opening of the cardboard container to close the cardboard container. The flaps may also include one or more tear strips to secure the flaps in a closed position until the cardboard container is opened for the first time.

In any case, in some examples, the packaging system may include a cardboard container 102, a liner 120, a capping material 140 and a lid of the cardboard container 400 without a plastic lid 150. In yet another embodiment, the Packaging system may include a cardboard container 102, a liner 120, a plastic lid 150 and a cardboard container lid 400 without capping material. In any case, the packaging system may be designed to include one, two or each of the capping material 140, the plastic lid 150 and the lid of the cardboard container 400. For example, in some embodiments, the packaging system may include only capping material 140 without plastic lid 150 or cardboard container lid 400.

Because the traditional buckets or buckets used to send viscous materials are normally cylindrical, a significant amount of space can be wasted during shipping because one cube cannot be aligned directly next to another, as can be seen in Figure 5A. In addition, as traditional buckets are so thick, each cube occupies more space and, in some cases, significantly more space than the packaging system of the present disclosure. This can best be seen in Figures 5A and 5B, which show how the same amount of product would be palletized in the present disclosure 520 and in the traditional hub system 510. As can be seen, each pallet 510, 520 contains 36 units; however, the height of pallet 520 of the present disclosure is considerably less than the height of pallet 510 of traditional cubes. In fact, adding another layer of the packaging system of the present disclosure to pallet 520 can only increase the height of the pallet a small amount, such as a couple of inches, compared to the traditional cube system 510 as shown in Figures 5A and 5C. Adding this additional layer may result in more product per pallet, and in some cases up to 33% or more of product. In addition to being able to store and / or send more, and in some cases significantly more product through this disclosure, the same amount of product weighs less, and in some cases significantly less, when packaged using the present disclosure instead of Traditional cubes This may make the product packaged using the present disclosure easier to move and, in some cases, less expensive to ship.

In practice, the coating of the present disclosure can be filled with a liquid, viscous material or particulate material before the coating is placed in the cardboard container, or while the coating is in the cardboard container. In existing conventional packaging systems, a liner can also be filled before being placed inside a box or after being placed in a box. However, if a sealing element were to be applied to the liner, the liner would have to be filled before being placed in the cardboard container. In that case, a sleeve or support member should be placed around the liner to stabilize the liner. Alternatively, in conventional packaging systems, the coating could be placed inside the cardboard container and then filled with material, but in that case, the coating could not be sealed with a capping material. One of these existing packaging systems is described in U.S. Patent No. 6,892,933. However, a novel and advantageous aspect of some embodiments of the present disclosure is that the liner can be filled when it is in the cardboard container, and the capping material can be sealed to the liner after the liner has been filled, and while the lining is still in the carton.

A further example of the prior art illustrated in Figure 6 shows the bottom wall 606 of a cardboard container 602. In this embodiment, the bottom wall 606 may contain access points 610 of the liner. Although four access points 610 of the coating are shown, it is noted that less or more access points 610 of the coating may be used as suitable or desirable for the intended application. In the embodiment shown, the access points 610 of the cladding are round, but they can be of any shape, such as, for example, among others, square, rectangular, triangular, oblong, etc. The access points 610 of the liner are areas that are trimmed or otherwise removed from the bottom wall 602 creating openings in the bottom wall 602, so that when the liner 120 is inside the cardboard container 602, it can be accessed to the liner and push it up from the bottom of the cardboard container 602. During the packaging process, the liner 120 can be placed in the cardboard container 602 to fill the liner 120 with material. Before sealing the capping material 140 in the liner 120, the liner 120 may be raised, for example, approximately A inch to 1 A inches, or any other suitable amount, to seal the capping material 140 to the liner 120. The liner 120 can be lifted to seal by pushing up the coating 120 through the points 610 of the liner on the bottom wall 606 of the cardboard container 602.

In some examples, a liner 180 can be removably placed inside the cardboard container 602 before the liner is placed in the cardboard container, as shown in Figures 1 and 6. The mat 180 can rest between the bottom wall 606 of the cardboard container 602 and the bottom of the liner. When the coating is pushed up for sealing through the access points 610 of the coating, the mat 180 can equalize the pressure applied to the coating and help stabilize the coating, allowing the full coating to maintain its shape when pushed towards above. The mat 180 may be made of corrugated cardboard. In other embodiments, the mat may be made of another material of paper, plastic, wood, metal or any other suitable material, or combination of materials. In one example, the mat 180 may be of any desirable thickness. For example, a relatively thin mat may be used with coatings that are not intended to be very heavy when filled, while a thicker mat may be desirable when the full coating is expected to be heavy. In other examples, a mat may not be used at all. In some embodiments, the mat 180 may be square or rectangular in shape and sized to fit tightly within the perimeter of the square or rectangular panels 104 of the side wall of the cardboard container 602. In alternative examples, the mat 180 may have other form that is not square or rectangular, such as, among others, circular, triangular, ovoid, etc. Similarly, the mat 180 does not need to be sized to fit tightly within the perimeter of the square or rectangular panels 104 of the side wall of the cardboard container 602, and in some examples, the mat 180 can be sized in such a way that the mat 180 covers at least a portion of one or more of the access points 610 of the liner. The access points and lining mats may be suitably used with any lining of the present disclosure, and may also be applied to existing packaging systems, such as, among others, those described in US Patent Number 6,892. 933

Once the full liner has been covered with a capping material, a plastic cap can be applied to the liner. In addition, a cardboard container lid can cover the plastic lid. In other embodiments, as mentioned above, the covering material of the liner may be covered only by a lid of the cardboard container. The packaging system can then be wrapped in or rolled up with plastic for palletizing and shipping.

A further example of the prior art of the present disclosure is a method for packaging and containing liquids, viscous or particulate materials as illustrated in Figure 7. In one example, a plastic liner can be placed inside a cardboard container 710 , either with the flange of the liner that extends over the upper edge of the cardboard container or positioned completely within the outer walls of the cardboard container. Once the liner is inside the cardboard container, it can be filled with a liquid, viscous or particulate material, or any combination thereof 712. After the liner has been filled, in some embodiments, a plastic lid can snap fit on the plastic liner to ensure the contents of the liner inside it 714. In some embodiments, a cardboard container lid can be secured over the plastic lid. 716

In another example, a capping material is fixed to the plastic liner after the plastic liner has been filled with the product. In some embodiments, fixing the capping material can be facilitated by pushing the plastic liner up and out of the cardboard container to more easily access and seal the capping material on the flange of the plastic liner. The plastic liner can be pushed up through the liner access points at the bottom of the cardboard container, as described above.

Another advantage of the present disclosure is that the system can be integrated into existing single and multiple head filling lines. In addition, the cardboard container 102 can be assembled using conventional equipment. The liner 120 can be installed and the cardboard container 102 and the liner 120 can be transported to the existing filler. Once the coating 120 has been filled with the product, a capping material 140 can be heat sealed in place to protect the product. A plastic lid 150 may or may not be installed on the liner 120. A lid of the secondary or tertiary cardboard container 400 may or may not be installed on the packaging system to protect the package during shipping. Subsequently, the packaging system can be wrapped in or rolled up with plastic for palletizing and shipping.

Figures 8-10 illustrate another exemplary example of a packaging system 300 in which the plastic liner 302 has an open-resealed cover assembly 304. It is appreciated that the packaging system 300 shown and described in the Figures 8-10 may include the features described in the other embodiments described herein. For example, the packaging system 300 may include a cardboard container 303, a plastic liner 302 having a flange 305, a plastic lid 309 and a cardboard container lid (not shown).

As illustrated in Figure 8, the opening-resealing capping assembly 304 includes a capping material 306 and an opening and resealing capping material 308. The capping material 306 may be similar to or include characteristics of the capping material 140 described above. Preferably, the capping material 306 is sealed to the plastic liner 302 and covers the entire open area 317 of the liner 302.

The capping material 306 can be heat sealed or laminated to the plastic coating 300 as described above. To access the contents of the interior of the plastic liner 302, the capping material 306 can be broken, torn or perforated. Preferably, the capping material 306 can be broken, torn or pierced using a sharp object such as a knife, scissors or the like. In some configurations, an indicator or mark may be provided indicating the user the preferred cutting area.

Preferably, when the capping material 306 is sealed to the plastic liner 302, the packaging system 300 has sufficient strength and rigidity to pass the appropriate shipping tests of the International Safe Transit Association ("ISTA"). In particular, the sealed packaging system 300 preferably has sufficient strength and rigidity to pass the ISTA-3E shipping test or an equivalent test that challenges the ability of the packaging system and its contents to resist transport risks. The capping material 306 also preferably acts as a tamper-proof system and can indicate to the user that the packaging system 300 has been tampered with if the capping material 306 is broken.

Preferably, the opening and resealing capping material 308 is heat sealed along its edges 320 to the capping material 306 and / or the plastic lining 302. The opening and resealing capping material 308 includes at least a first layer 314 and a second layer 324, such as a sealing layer, which are generally coextensive and adhered to each other. In the preferred embodiment, the second layer 324 is permanently fixed to the first layer 314 and the first layer 314 is positioned so that it is oriented towards the inside of the plastic liner 302. The first layer 314 and the second layer 324 can be substantially of the same size or in some configurations, the second layer 324 may be smaller than the first layer 314. In the example illustrated in Figure 8, the liner 302 is substantially rectangular and the capping material 308 has four edges 320 corresponding to the geometry of the opening of the lining 302. It will be appreciated that other geometries of the lining can be used, for example and without limitation, the opening of the lining 302 could be circular, or polygonal with more or less than four sides. The first layer 314 includes a central portion 318 and a remaining area 319 adjacent to the central portion 318. The central portion 318 is located at a predetermined distance from the edge 320 of the opening and resealing capping material 308.

The central portion 318 is defined by four edges, wherein at least three of the edges are separate edges 322. The separated edges 322 are preferably perforated or a previously torn groove that separates the three edges of the central portion 318 from the remaining area 319 of the first layer 314. The fourth remaining edge or edge of the central portion 318 is preferably fixed to the remaining area 319 to act as a hinge 315, so that the central portion 318 can be removed to expose the capping material 306 located beneath it. . The central portion 318 of the opening and resealing capping material 308 can then be resealed to seal the open area 317 of the plastic liner 302 when the capping material 306 has been broken.

The second layer 324 preferably includes an adhesive portion 326 extending beyond the sides of the central portion 318 (as shown in Figure 10). The adhesive portion 326 includes a resealable adhesive 310 on the underside of the adhesive portion 326 oriented inwardly of the plastic cover 302. When the user removes the central portion 318, the adhesive portion 326 with the central portion 318 is also removed. The adhesive portion 326 preferably includes a resealable adhesive material that can be sealed and resealed several times to facilitate resealing the central portion 318 against the opening and resealing capping material 308, for example, against the portion of the first layer 314 adjacent to the central portion 318 and edge 320.

Preferably, the first layer 314 is preferably made of a metallized material or structure, such as polyethylene terephthalate, mono-oriented polypropylene film or COEX NYL / PE or a combination thereof that acts as a barrier against oxygen and moisture. The metallized structure also has sufficient hot adhesiveness and sealing strength such that the packaging system 300 is suitable for packaging both hot and cold materials. The first layer 314 may also be made of an opaque material to reduce the amount of light entering the interior of the plastic liner 302. In some embodiment, the first layer 314 may be made of material that reflects or reduces exposure to the ultraviolet light.

In the preferred example, the opening and resealing cover material 308 includes a tongue 312 that is not adhered to the cover material 306, so that a user can easily grasp the tongue 312 and remove the central area 316 from the cover material 306 of the opening and resealing cover material 308. In some configurations, the flange may be a portion of the first layer 314 or the second layer 324. In other configurations, there may be no flange.

Figure 11 illustrates an exemplary method of using the packaging system 300 shown in Figures 8-10. The contents, such as liquid, powder, solids, etc., are stored in the plastic coating 300 (step 450). The capping material 306 and the opening and resealing capping material 208 are heat sealed to the plastic liner 302 (step 452). As shown in Figure 9, the plastic coating 300 can optionally stored inside a cardboard container 303 with a plastic lid 309 and / or a cardboard lid (not shown). The packaging system 300 is then transported, for example, by land or air transport, to the user. Once received, the user can access the content stored within the plastic coating 300 by first removing, if necessary, the plastic cover 309 and / or the cardboard cover (not shown). Next, the user removes the central portion 318 of the opening and resealing capping material 308 and exposes the capping material 306 located below (step 454). For configurations in which the opening and resealing capping material 308 includes a tab 312, the user can grasp the tab 312 using, for example, his fingers to facilitate the opening of the opening and resealing capping material 308. The user break the capping material 306 to access the contents within the plastic liner 302 (step 456). The user reseals the contents within the plastic coating 302 by pulling the central portion 318 towards the plastic coating 302 and resealing the adhesive portion 326 against the remaining area 319 of the first layer 314 (step 458). Optionally, the plastic lid 309 and / or the lid of the cardboard container may be arranged on the plastic liner 302.

By having a plastic liner 302 with an opening-resealed cap assembly 304, the contents of the interior of the plastic liner 302 can be sufficiently secured and protected during transport. In addition, because the opening of the plastic liner 302 can be resealed, the packaging system 300 can be used to store the contents even after the packaging system 300 has been opened. This saves the additional cost of storing the contents in separate packages.

Alternatively, the second layer may be a strip of adhesive that is smaller than that of the central portion 318 and with a side fixed to the central portion 318 and a second side extending from the sides of the central portion 318 and which It has the resealable adhesive. In the above description, several embodiments of the present disclosure have been presented for purposes of illustration and description. They are not intended to be exhaustive or limit the invention to the specific form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments have been chosen and described to provide the best illustration of the principles of the invention and its practical application, and to allow a person skilled in the art to use the invention in various embodiments and with various modifications that are suitable for the particular use contemplated. . All these modifications and variations are within the scope of the invention as determined by the appended claims when interpreted according to the extent to which they are entitled, legally and equitably.

Figures 12-14D illustrate an exemplary embodiment of a packaging system 1000 according to the present invention in which the plastic liner 1050 has an opening and resealed lid assembly 1040. It is appreciated that the packaging system 1000 shown and described in Figures 12-14 may include one or more of the features in any combination described in the other examples described herein, or the packaging system may not include any of the features previously described, so that the scope of the invention is defined by the claims. For example, the packaging system 1000 may include any combination of a cardboard container 1002, a plastic lining 1050 having a flange 1005, an opening and resealing lid assembly 1005 and a cardboard lid 1060.

As illustrated in Figure 12, the cardboard container 1072 having side walls 1074 can receive the liner 1050. The flange and the lower wall of the liner 1050 can support the liner 1050 in the cardboard container 1072. A set of opening lid and resealing the lining 1050 by the tab 1055. A cardboard cover 1060 may include the lining 1050 and the opening and resealing cover assembly inside.

As illustrated in Figure 13A, the opening and resealing lid assembly 1040 includes a plurality of layers. A capping material 1006 and an opening and resealing capping material 1008. Capping material 1006 may be similar to or include features of capping material 140 or 340 described above. The cover material 1006 can be sealed to the plastic liner 1050 and cover the entire open area 1017 of the liner 1050. The cover material 1006 can be a transparent layer or an opaque layer or a translucent layer. The capping material 1006 may be any suitable material used in the applicable industry. For example, coextruded nylon can be used. Capping material 1006 may have a thickness of 0.0254 to 0.508 mm. In one example, the capping material may have a thickness of 0.1016 mm which, when combined with the opening and resealing capping material 1008, the opening and resealing cap assembly 1040 may have adequate rigidity and flexibility. For example, the capping material 1008 can be flexible enough to fold over itself or roll up forming a roll while it is open. The capping material 1008 can be rigid enough not to fall into the opening by its own weight. The capping material 1006 may be tightly heat sealed or laminated to the plastic coating 1050 as described above.

The opening and resealing capping material 1008 comprises a first layer 1014 and a second layer 1024. A layer may be an operable layer for resealing an open package. A layer can be a reinforcing layer. The reinforcing layer can be operable to prevent the opening and resealing capping material 1008 from bending over itself by its own weight or by small forces. The second layer may remain attached to at least a portion of the first layer. For example, there may be multiple portions of the first layer as explain below. The second layer may be detachably connected to a portion of the first layer but remain attached to another portion when the first layer opens and closes along its opening.

The first layer may be any material that provides support for capping material 1006 or that provides a suitable oxygen barrier. For example, the first layer 1014 may be a metallized oriented polypropylene (MOPP) layer. Metallized films are polymer films coated with a thin layer of metal, usually aluminum. They offer the shiny metallic appearance of an aluminum foil with reduced weight and cost. Metallized films are widely used for decorative purposes and for food packaging. Metallization is carried out by a process of physical vapor deposition. Aluminum can be a typical metal used for deposition, but other metals such as nickel or chromium are also used. The metal is heated and evaporated by vacuum. This condenses on the cold polymer film, which unwinds near the metal vapor source. This coating is much thinner than a metal sheet (although a metal sheet can also be used in several embodiments) could be made, according to several embodiments in the range of 40 g to 100 g. For example, the first layer may be approximately 70 g to MOPP. In various embodiments, polypropylene, nylon, polyethylene, molten polypropylene and polyethylene terephthalate (PET) can be used with metallization.

According to various embodiments, the second layer can be formed from a material similar to that of the first layer. However, the second layer can be formed without metallization. The second layer 1024 can keep the first layer 1014 closed with an adhesive applied to one side. Like the first layer, the second layer can be formed of polypropylene, nylon, polyethylene, molten polypropylene and polyethylene terephthalate (PET). The second layer can be formed from a variety of thicknesses such as 30 ga to 90 ga. For example, the second layer 1024 may be formed by approximately 50 g of PET.

According to various embodiments, the opening and resealing cover assembly 1040 may be composed of a second layer 1024 battery that is 48 g PET with ink applied to non-stick areas (such as the pull tab, see below) and with a adhesive applied on one side, the first layer 1014 which is a 70 ga metallized OPP with an adhesive on both sides and a capping material 1006 which is a 4 mil COEX nylon film bonded to one side of the first layer. This embodiment and similar embodiments can be used to package hot and cold materials. The assembly can have excellent hot adhesiveness and sealing resistance. The metallized structure provides the whole with an improved barrier against oxygen and moisture and good rigidity, while maintaining some flexibility to keep the central portion 1018 (discussed in more detail below) movable for opening.

To access the content within the plastic liner 1050, the capping material 1006 can be broken, torn, cut, punctured or the like. For example, an X-shaped cut can open capping material 1006 to provide access to the container. An example of cutting 1023 through the capping material is illustrated in Figure 13D. Preferably, the capping material 1006 can be broken, torn or pierced using a sharp object such as a knife, scissors or the like. In some configurations, an indicator or mark may be provided indicating the user the preferred area for cutting.

As with other embodiments, the 1000 packaging system has sufficient strength and rigidity to pass the appropriate shipping tests by the International Safe Transit Association ("ISTA"). In particular, the sealed packaging system 1000 preferably has sufficient strength and rigidity to pass the ISTA-3E shipping test or an equivalent test that challenges the ability of the packaging system and its contents to resist transport risks. The capping material 1006 also preferably acts as a tamper-proof system and can indicate to the user that the packaging system 1000 has been tampered with if the capping material 1006 is broken.

The opening and resealing capping material 1008 is heat sealed along its edges 1002 to the capping material 1006 and / or to the plastic coating 1050. The opening and resealing capping material includes at least a first layer 1014 and a second layer layer 1024, such as a sealing layer, generally coextensive and bonded together. In the preferred embodiment, the second layer 1024 is permanently fixed to the first layer 1014 and the first layer 1014 is arranged so that it is oriented towards the inside of the plastic liner 1050. The first layer 1014 and the second layer 1024 can be substantially of the same size or in some configurations, the second layer 1024 may be smaller than the first layer 1014. The capping material 1008 may be operable to rest flat, detach flat (e.g., figure 13C) and roll up (e.g., figures 12 and 13D). The metallized layer can provide adequate rigidity to control the characteristics of the capping material 1008.

According to various embodiments, the coating 1050 can have any number of sides or any shape. For example, the liner 1050 may be substantially rectangular and the capping material 1008 may have four edges 1002 corresponding to the geometry of the opening of the liner 1050. It will be appreciated that other lining geometries can be used, for example and without limitation, the opening of the lining 1050 could be circular or polygonal with more or less than four sides.

The first layer 1014 includes a central portion 1018 and a remaining area 1019 adjacent to the central portion 1018. The central portion 1018 is disposed at a predetermined distance from the edge 1002 of the opening and resealing capping material. The central portion 1018 is separated from the remaining portion 1019 along at least one edge 1022, so that the central portion 1018 can be moved to expose the capping material 1006 (which can be considered a second capping material) located beneath it. . The cover material 1006 may be defined by at least one edge 1027. The cover material 1006 may be sealed to the remaining portion 1019 and to the central portion 1018 through the separated edge 1022. The opening and resealed cover material 1008 is Resealable to seal the contents of the plastic liner when the capping material has broken. The separated edge 1022 of the central portion 1018 may end in an inwardly directed curve 1029. In another example, as illustrated in Figure 13G, 1022 may end in an outwardly directed curve 1031. The curve (curved inward or inward outside) forms a turn of at least 90 °. Curve 1029, 1031 can form a rotation of about 180 °. The termination points 1033 are turned towards where the central portion 1018 is opened such that when the central portion is opened and bent through a hinge section 1015, the tension at the edge termination is reduced because in action opening is not pulled towards completion but away from it, reducing the likelihood of cracking. Once the central portion 1018 moves to an open position the second capping material 1006 is exposed under it.

In several examples, the central portion 1018 may be defined by the at least one edge 322. The edge may define a single groove for the shaft or may define any of a variety of ways to create an opening in the first layer 1014. In several examples, the central portion 1018 may be defined by four edges as illustrated in Figures 13A-G. Although as illustrated in Figure 13F, the at least one edge may have a variety of shapes, some of which are illustrated as examples, but one skilled in the art will recognize that, according to this disclosure, any shape can be used. In one example, at least three of the edges. The separated edges 1022 may be perforated, cut or cracked that separate the three edges of the central portion 1018 from the remaining area 1019 of the first layer 1014. The fourth remaining edge or edge of the central portion 1018 is preferably fixed to the remaining area 1019 for act as a hinge 1015 so that the central portion 1018 can be removed to expose the capping material 1006 located beneath it. The central portion 1018 of the opening and resealing capping material 1008 can be resealed to seal the open area 1017 of the plastic liner 1050 when the capping material 1006 has broken. Since the first layer is opened by the hinge, the second layer 1024 remains attached to the central portion 1018 while separating from the remaining edge 1018.

The resealing is possible because an adhesive portion 1026 is superimposed on the separated edges 1022 from the central portion 1018 to the remaining area 1019, so that when the adhesive portion 1026 is attached to the remaining area 1019 it is also attached to the central portion 1018, sealing the opening and resealing capping material. The adhesive portion 1026 may have a distance D as width as illustrated in Figures 13B-C. D can often be greater than 1/8 of an inch. In several examples, D can be from% to A inch wide. The adhesive portion 1026 includes a resealable adhesive 1010 on the bottom surface of the adhesive portion 1026 oriented inside the plastic cap 1002. As the user removes the central portion 1018, the adhesive portion 1026 with the central portion is also removed. 1018. The adhesive portion 1026 preferably includes a resealable adhesive material that can be sealed and resealed several times to facilitate resealing of the central portion 1018 against the opening and resealing capping material 1008, for example, against the portion of the first layer 1014 adjacent to the central portion 1018 and the edge 1002. The 1024 also extends through the curve 1029 and the termination points 1033.

As indicated above, the opening and resealing capping material 1008 includes a tongue 1012. The tongue 1012 may have an adhesion similar to the rest of the second layer 1024 or the tongue 1012 may have a lower adhesion compared to the rest of the layer 1024. In various embodiments, the tongue 1012 may not be adhered to the capping material 1006. This may allow the user to easily grasp the tab 1012 and remove the central area 1018 of the opening and resealed capping material 1008 of the material. capped 1006. In some configurations, the tongue may be a portion of the first layer 1014 or the second layer 1024. In other configurations, there may be no tongue. In one example, the separated edge 1022 of the central portion 1018 includes a first edge 1035 and a second edge 1037 (see Figure 13C). The opening and resealing cover material 1008 includes a corner tab 1012 which is defined by an area in which the first edge 1035 and the second edge 1037 meet in a corner. The tongue is operable to extend away from the surface of the opening and resealed capping material 1008, so that it can be grasped and pulled away. The tongue 2012 can be moved in such a way that it can be operatively removed from the first cover material 1014. This separation of the cover material 1014 allows the separation between the portion of the second layer 1024 and the first layer 1014 which is joined along the Remaining portion 1019. This joint may be adjacent to the first edge 1035 and the second edge 1037. The second layer 1024 is separable from the remaining portion 1019 starting at either side and next to the tongue 2012. The separation continues to move along of the first edge 1035 and the second edge 1037 as the tongue moves away from the first cover material 1014. The separation advances distally away from the tongue 1012, since the tongue 1012 is separated from the first cover material 1014. In other configurations , the tongue may be located at an intermediate length along any edge, or there may be no tongue.

Figure 14A-D illustrates several embodiments of the coating 1050. With respect to the various embodiments as It is illustrated in Figures 14A-E, all other embodiments, features and examples described with respect to other embodiments may also be combined herein. The liner 1050 may comprise at least one side wall 1052. In the example shown in Figures 14A-E, the liner 1050 includes four side walls 1052 and a bottom wall 1053. The four side walls 1052 define an open area 1017. In the termination of the side walls 1052 distal to the bottom wall 1053 is a flange 1056. The flange 1056 may include a flange 1055 extending outwardly (ie, away from each of the side walls 1052). The flange 1055 may include a skirt 1057. The skirt 1057 may extend downwards (ie, towards a plane defined by the bottom wall but not towards the side walls).

According to various embodiments, the liner 1050 includes a plurality of positioning elements. The liner 1050 is operable to be arranged inside a cardboard container 1072. The cardboard container includes walls 1074 that define its perimeter. The lining 1050 and the cavity defined by the walls 1074 can be housed inside each other, so that the lining 1050 can be located inside the cardboard container 1072. The lining 1050 can still move inside of the cardboard container. The packaging set 1000 is operable to be used safely and protected with a wide range of contents. As such, in various embodiments, a perfect fit between the cardboard container 1072 and the liner 1050 can improve the usefulness of the packaging assembly 1000. To this end, in various embodiments, the packaging assembly 1000 may include elements to prevent movement . The elements for preventing movement may include protrusions that are in contact with the cardboard container 1072. For example, these may include skirt ribs, wall protuberances, specialized corners or any feature that limits movement between the cardboard container and the coating.

In several examples, a liner 1050 may rest on the upper edge of the wall 1074 by the flange portion 1055 extending from the flange of the liner 1050. The skirt 1057 provides a pocket between the side wall 1052 and the inner surface 1059 of the skirt 1057 to receive the wall 1074 to help a more perfect fit of the packaging assembly 1000. The skirt can also include a plurality of ribs 1071. The plurality of ribs 1071 can extend from or to the surface 1059 of the skirt 1057. The plurality of ribs 1071 extends from the flange portion 1055 to the end of the skirt. By forming these protrusions inwards or away from the skirt 1057, the surface 1059 of the skirt is strengthened. The ribs can also act as spacers to form a better fit around the wall 1074. For example, the ribs 1071 can extend to the side wall 1052 at a plurality of finite points. These finite points could interfere with the wall or simply close the space towards the wall 1074 when the lining 1050 is installed in a cardboard container 1072 and the wall 1074 extends into the cavity between the skirt 1057 and the side wall 1052. Due to that the points are separated and friction and pressure are minimized, even if they interfere, they may not prevent the lining 1050 from engaging with the cardboard container 1072. The skirt 1057 may also include a widening 1073 extending away from the side wall. The widening 1073 can also extend around the perimeter. The widening can be operable to help the skirt 1057 receive the wall 1074 when the lining 1050 is inserted into the cardboard container 1073. When the widening 1073 is separated from the side wall 1052, the widening 1073 forms a wider entrance for receive wall 1074 in the space between skirt 1057 and side wall 1052.

The outer corner of the skirt can be any type of corner. For example, it could be round as the intersection of the wall 1052. In another example, the corner of the skirt could be different from the corner of the wall 1052. For example, the corner of the skirt can be in a way that helps secure the cardboard container 1073. In one example, the side walls 1052 may include a rounded corner near the side wall and the skirt may include an outer corner near the skirt. The outer corner can interact with other elements (see below) or its shape, alone, can improve the pressure on the cardboard container with the resulting improved fit.

The skirt includes a rib 1079 that generally extends parallel to the flange portion in at least one of the outer corners on the side of the skirt. The rib 1079 may be located close to the flange portion. The rib may form a projection that helps grip to lift the liner 1050 or the rib may be a stiffening reinforcing element.

According to various embodiments, the side walls 1052 may include elements to improve the fit with the cardboard container. For example, in each of the corners of the side walls 1052 a protrusion adjacent to the end of the skirt can be located. The protuberance 1075 may be located in front of the skirt and separated from the protuberance 1075 by the flange portion. In this way, there is a space between the end of the skirt and the bump. As indicated above, the skirt may have an outer corner connection and the corner connection may be located adjacent to another element, such as protuberance 1075, which may also be located at the corners. As such, the cardboard container can even receive a tighter fit when disposed between the outer corner and the protuberance 1075. The protuberance can be arranged anywhere in the liner 1050, so that it is operable to exert pressure out when the The lining is slipped into a cardboard container 1072. However, by placing the protuberance 1075 in front of the skirt 1057 a sandwich is formed, potentially increasing the pressure from both sides on the wall 1074 and improves the fit. The protuberance 1075 may be a protuberance that curves outwardly and moves away from the side wall 1052. The protuberance 1075 may have a smaller curvature than the surface of the side wall 1052, such as the surface in the rounded corner. The lower curvature may result in better contact between the outer surface of the protuberance and the cardboard container, compared to the outer surface of the rounded corner. This is because the smaller curvature can make closer and more complete contact with the cardboard container in a place like a corner. According to various embodiments, the protuberance 1075 may include a rib 1077. The rib 1077 can bisect the protuberance that extends from one side of the protuberance 1075 near the bottom wall 1053 to one side of the protuberance near the flange 1055. The rib 1077 can reinforce the protuberance so that it is capable of exerting greater pressure outwards, for example on the cardboard container 1072.

According to an example method 1100 to form the opening-resealed cover assembly 1040, the first layer can be obtained (step 1110). The first layer as discussed above may be a metallized OPP layer. This can come in large rolls of material. The central portion can be cut in the first layer (step 1120). As explained briefly above, the first layer can be cut, torn, punctured or the like to form the separate edge that defines the central portion. Once the first layer is prepared and the central portion is formed, the first layer can be attached to an additional layer. In one embodiment, it can be attached to the second layer, which can be the layer that opens and reseals with the first layer. Alternatively, the third layer of material can be attached to the first next layer (step 1140). Any order is contemplated in this document. The third layer of material may be the cover material 106 which can act as the tamper-proof seal. The third layer can be heat sealed to the first layer. The two layers can be cut so that they are coextensive with each other. A finished product may be formed by a plurality of layers. Each can provide a separate function, for example, tamper-proof, oxygen barrier, opening-resealing characteristics.

According to an example process, as illustrated in Figure 16, a system can prepare the packaging assembly 1000 in a production line. The system can receive cardboard boxes from a box owner, obtain coatings, fill the liner, seal the opening-resealed assembly to the liner, place the liner inside the cardboard container, place a cardboard lid on the cardboard container and then palletize the final packaging set.
