Definitions

• the present invention relates to a snack container with a three dimensional base and a two dimensional top.
• the invention relates to, in a preferred embodiment, an interior-lined paperboard container filled with a snack food product that is sealed with a flat, two dimensional, seal at the top of the container yet has a square, three dimensional base, such as a square base.
• Such container is suitable for display on, for example, wire display racks in a convenience store setting. It is also shaped such that it fits into a standard car cup holder and is easy to hold.
• the container opens by use of a tear strip or tear feature slightly below the top of the container that removes the container top and allows for easy access to the snack food contained therein and a natural reclose functionality due to the container geometry.
• Snack foods are typically packaged in flexible bags called pillow bags.
• Pillow bags are suitable for display on wire racks, as they can be easily attached to the rack by a clip on the top seal of the pillow bag or by inserting a wire display rod through a hole in the top seal. This attribute can also allow for vending in vending machines that use wire hangers. Because pillow bags are flexible, however, they are not conducive to protecting the product once the bag is opened and the gas pressure inside the pillow bag is released. Pillow bags are also not shaped for use with certain convenience accessories such as a cup holder in an automobile or a cup holder in a seat at an entertainment venue (ballpark, movie theater, etc.).
• Pillow bags also do not naturally reclose once they are opened.
• a pillow bag typically requires some type of external clip to close the bag such that the product does not fall out of the bag if the bag falls on its side.
• Another container typically used for snacks is a paperboard rectangular container such as traditionally used for Cracker Jack® and other similar products. These rectangular paperboard containers have the benefit of protecting the product even after the container has been opened.
• the container also allows for package to mouth consumption of the product contained therein.
• such paperboard rectangular containers cannot be displayed in the same manner as a pillow bag, because such containers do not have a flat or two dimensional top seal nor do they typically have a hole through the top through which a display rod can be inserted to hang the package for retail display.
• the rectangular boxes, depending on the dimensions, are also not typically suitable for use with cup holders.
• the paperboard rectangular container further typically requires a folding or manipulation of the top to reseal the container.
• FIG. 1 Another container used in the snack industry is the cylindrical container with a top cap seal, such as is used for the Lay's Stax® chip product.
• the cylindrical container typically made either of a plastic material or paperboard material, readily protects the product even after the cylinder has been opened at the top.
• the cylindrical container is suitable for use with cup holders and works well with one-hand use.
• the cylindrical container cannot typically be displayed on the wire racks used for pillow bag display, since the cylindrical container has neither a two dimensional top seal nor a hole through which a display rod can be inserted.
• the cylindrical container requires a manual application of a top cap in order to reseal the container.
• a snack container for use with savory or sweet food products, that can be displayed on a wire display rack in a retail setting or hung in a vending machine, just like a pillow bag and yet that comprises the rigidity of a paperboard or plastic container for protecting the product.
• such container should be suitable for use with cup holders and fit economically into the human hand for one-hand use once opened and package to mouth consumption of the product contained therein.
• the container should be designed to naturally reclose without the need for folding or the application of an external clip or top cap.
• Such container should be capable of carrying graphics on the exterior and have interior barrier properties sufficient to protect the snack product and promote shelf stability.
• the invention uses a paperboard construction lined on the interior of the container with a barrier material, typically a combination of a low density polyethy base layer with aluminum foil or some other metalized layer, thus promoting shelf stability of the product contained therein.
• the container comprises a relativity square base that transitions through a geometric design utilizing folds and creases to a flat two dimensional top seal.
• fold or “folds” used herein means a bend in the material of greater than 89 degrees.
• crease or “creases” used herein means a bend in the material of less than 90 degrees.
• This transition from a three dimensional base to a two dimensional top is accomplished by two opposed folds running vertically along opposite edges of the container from opposite corners of the square base to opposite edges of the top seal. Disposed between these two folds are two "V" shaped creases which start at opposite corners of the square base and terminate at a point below the top seal at each of the previously mentioned folds. This gives rise to a container that has side walls shaped of four right triangles divided by two isosceles triangles all below the point where the "V" shaped creases intersect with the folds below the top seal.
• a horizontal tear feature is constructed just below the top seal in order to open the container and remove the top seal. Once this happens, the container can be squeezed from the folds, opening the mouth of the container and allowing for access to the snack product contained therein and direct package to mouth consumption. Because of the geometry of the construction, the container substantially recloses once the pressure on the folds ceases.
• the container is of such dimensions that it easily fits in a cup holder and ergonomically fits well within the human hand for one hand use.
• the use of an end seal at the top allows for the retail display of the container in a similar fashion to that used for pillow bags in both retail settings and vending machines.
• a hole or opening is fashioned in the center of the top seal such that the container can be hung off a rod on a wire display by pushing the rod through the hole.
• the flat end seal also allows the container to be hung on displays using clips.
• Figure 1 is a depiction of a paperboard blank used for the constructions of one embodiment of the present invention.
• Figures 2 A, 2B, 2C, and 2D depicts one embodiment of the preferred invention after construction
• Figure 3A & 3B depicts one embodiment of the preferred invention with the top seal removed.
• Figure 1 depicts a paperboard blank used to construct one embodiment of the container.
• the blank 102 is initially flat and has a front side (depicted in Figure 1) and a back side (not shown).
• the front side of a side flap 104 is mated with the back side of the blank 102 along the left side 106 of the blank 102.
• a left top section 108 and a right top section 110 are mated together.
• a hole or opening 112 is made in the top left section 108 and a corresponding hole or opening 114 is made in the top right section 110.
• the holes 112, 114 align, thereby giving the product the functionality of having a hole or opening at the top of the container through which a wire rod can be inserted for retail display or vending.
• FIG. 1 Also shown in Figure 1 are two "V” shaped creases 166.
• fold or “folds” means a bend in the blank 102 material of greater than 89 degrees.
• crease or “creases” used herein means a bend in the blank 102 material of less than 90 degrees.
• a barrier layer such as a film consisting of MG bleached kraft, low density polyethylene, aluminum foil, and Surlyn 1652 sealant, is attached to the paperboard blank 102 on the back side of the blank 102 such that when the side flap 104 is sealed to the left side 106, the partially constructed container then has a barrier layer on the interior of the partially constructed container.
• the paperboard is, in a preferred embodiment, .014, .015, .016, .018, or .020 caliper paperboard and is SBS, SUS, CCNB, or some combination thereof.
• the front of the paperboard includes a graphical treatment that includes, but is not limited to: UV (high gloss) coating, matte coating, registered matte or gloss coating, embossing, and/or debossing. Additionally, specialty inks can be used such as thermochromic and/or phosphorescent inks.
• a partially constructed container as described above, is loaded with a product through the base of the partially constructed container.
• a product includes, but is not limited to, bite size savory or sweet snack foods, such as: chips or crisps, nuts, popcorn, hard candy, extruded snacks, puff snacks, fried snacks, baked snacks, fruit pieces, soft candy pieces, chocolate, pretzels, cereals, and mixtures thereof.
• bite size savory or sweet snack foods such as: chips or crisps, nuts, popcorn, hard candy, extruded snacks, puff snacks, fried snacks, baked snacks, fruit pieces, soft candy pieces, chocolate, pretzels, cereals, and mixtures thereof.
• the distance 124 from the top of the blank 102 to the bottom of the bottom flaps 116, 118, 120, 122 is about 10 inches.
• the distance 126 from the top of the blank 102 to the top of the bottom flaps 116, 118, 120, 122 is about 8 inches.
• the distance 128 from the top of the top sections 108, 110 to the bottom of the top sections 108, 110 is about .5 inches.
• the length 130 and width 132 of the side flap 104 is approximately 7.134 inches and .5 inches, respectively.
• the width 134 of the blank 102 less the side flap 104 is approximately 8 inches.
• the maximum width 136 of the slightly tapered bottom or base flaps 116, 118, 120, 122 is approximately 2 inches, thereby resulting in a square base upon final construction of the container of about 2 inches by 2 inches.
• the distance 138 from the top of the blank 102 to the top of the "V" shaped creases 166 is between 1 inch and 1.75 inches, and in a preferred embodiment is about 1.5 inches.
• Figure 2A is a front view of the container.
• Figure 2B is a top perspective view of the front, right side of the container.
• Figure 2C is a bottom perspective view of the front right side of the container.
• Figure 2D is a view of the right side of the container.
• the container in a preferred embodiment consists of a square base 250 and a two-dimensional flat top seal 252.
• the left side of the container is defined by a left fold 256.
• the right side of the container is defined by a right fold 254.
• the right fold 254 starts at the right corner 258 of the square base 250 and runs to the top right point 260 of the end seal 252.
• the left fold 256 starts at the left corner 262 of the base and runs upward to the top left edge 264 of the top seal 252.
• Figure 2A shows a front view of the container and depicts a "V" shaped crease 266 that starts at the front corner 268 of the square base 250 and runs to a point 270 in the horizontal plane that is below the top seal 252 and intersects with the right and left folds 254, 256.
• the container thus has two side walls which are in planar contact with each other above the horizontal crease 272 that defines the bottom of the end seal 252. Also depicted in the end seal 252 is a hole or opening 274.
• the geometry of the two folds 254, 256 and the two "V" shaped creases 266 provides a container (below the termination points 270 of the top of the "V" shaped creases 266) defined by four right triangle shaped side walls 276 and two isosceles triangle shaped side walls 278.
• the embodiment of the container depicted in Figures 2A, 2B, 2C, and 2D has a horizontal tear feature 280 along at least one side wall and, in a preferred embodiment, through both side walls, located below the top seal 252 and above the termination points 270 of the top of the "V" shaped creases 266.
• This tear feature 280 can be a perforation pattern cut partially through the container material, an embedded rip cord in the container, or other modes of separating portions of paperboard known in the art.
• the exact dimensions of the formed container can vary from embodiment to embodiment.
• the dimension of the square base 250 is less than 3 inches by 3 inches. In a more preferred embodiment the dimensions of the square base 250 is about 2 inches by 2 inches.
• the length of the two folds 254, 256 is less than 10 inches long each and greater than 6 inches long each. In a more preferred embodiment the length of the two folds, 254, 256 is less than 9 inches long each and greater than 7 inches long each.
• the vertical distance from the top corners 260, 264 of the top seal 252 to the top 270 of the "V" shaped crease 266 is between 1 inch and 2 inches.
• Figures 3A and 3B depict the container after the application of the tear feature such that the top has been removed, allowing access to the product found inside.
• Figure 3A shows a container that is fully opened at the top, thereby allowing for direct package to mouth consumption of the product.
• the configuration of the container shown in Figure 3A occurs when the consumer squeezes the package along the folds 354, thereby opening what becomes the top of the container 382 once the top portion above the tear feature has been removed.
• Due to the geometric design of the container when the consumer releases pressure on the folds 354 the container returns to a substantially closed position at the top 382 as depicted in Figure 3B. This results in the container being predisposed to a substantially closed position when not being squeezed open by a consumer's hand.
• one method for constructing an embodiment of the container involves first cutting a paperboard blank having a graphics layer on one side and a barrier layer on the other side. Such cutting results in a flat blank having a side flap 104 along one edge and four base flaps 116, 118, 120, 122. The blank 102 is then folded and creased such that there is a fold 105 lengthwise down the middle of the blank and creases 166 that form two "V" shaped creases on either side of the middle fold 105. The two lengthwise edges 106, 107 of the blank 102 are affixed together by use of the side flap 104. A top section 108, 110 of the blank 102 is affixed together thus forming an end seal and resulting in a partially constructed container with an opening in its base.
• the method can include the step of scoring a tear feature 180 near the top of the blank 102. Further, openings can be cut in two locations 112, 114 near the top of the blank 102 such that the openings 112, 114 align upon formation of the end seal, thus forming a single opening through the end seal through which a rod can be inserted for displaying the container in a hanging configuration.
