Firstfront panel 16 can also be connected to each of the twoside panels 12, and at least a portion of eachedge 30 betweenfirst front panel 16 and each of theside panels 12 can be arcuate.Arcuate edges 30 connectingfirst front panel 16 andside panels 12 result in a bowing out offirst front panel 16 so that it is at least partially outwardly-convex, defining a cavity between firstfront panel 16 andback 14. This allows an area for one or more inner packets 32 (FIG. 2 ) containing products to be placed therein. Although any number of products can be placed withininner packet 32, examples herein can include granulated or powdered drink mixes. - As shown in the
FIGS. 10 and 11 ,container 10 can have anoptional shrink band 23.Shrink band 23 can be applied to envelop at least part ofcontainer 10 prior to use by a consumer (See,FIGS. 10-11 ) to inhibit access to the contents disposed therein.Shrink band 23 can be transparent, opaque, or have printed layers.Shrink band 23 can be formed from a variety of film materials such as oriented polypropylene (OPP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), and preferably glycol-modified polyethylene terephthalate (PETG).Shrink band 23 can be between about 40 to 70 microns, preferably about 45 to 55 microns, and most preferably about 50 microns.Shrink band 23 can also haveperforations 45 to allow easy removal by a user. As shown inFIG. 11 ,perforations 45 can be two substantially parallel spaced lateral perforations spanning awidth shrink band 23. - Also, as shown in the figures, a pattern or irregularity can be die cut into a container edge. As shown, at least one
tab 21 can be added tobottom edge 20.Tab 21 can facilitate the retention of ashrink band 23 as shown inFIGS. 10 and 11 . For example, in embodiments having a longitudinal shrink band (shown), the shrink band could potentially be removed laterally and replaced without evidence to the user when the engaged edges are smooth and/or undistorted. The irregular pattern formed by the at least onetab 21 can inhibit the lateral removal of the shrink band. Further,tab 21 can be used to provide tamper evidence whenshrink band 23 is configured to rupture if lateral movement of the band is attempted. In preferred shrink band gauges,tab 21 would also be configured to provide sufficient rigidity to rupture the film upon attempted lateral removal. Several pattern variations to produce an irregular edge tocontainer 10 are possible.FIGS. 12-15 show just a few of these potential variations. Also, as shown inFIGS. 4 and 5 , these irregularities can be formed from the dies cutting the container blanks. - It is also noted that the irregular pattern, such as
tabs 21, can be formed on any of the package sides, such as bottom and/or top side, and left side and/or right side so long as at least one of the irregular patterns engages theshrink band 23 as described. In embodiments where a right side and/or left side irregular pattern is included, shrinkband 23 would envelop the container in a lateral direction. Thus, as shown, preferably threetabs 21 can be provided and the shrink band configured to engage all three tabs. - First
front panel 16 can also include aslot 28 for receiving alower edge 26 of secondfront panel 18 to closecontainer 10. Secondfront panel 18 can at least partially overlap firstfront panel 16. In exemplary embodiments, whencontainer 10 is initially purchased and is unopened, an adhesive means can be used to retain the firstfront panel 18 over secondfront panel 16. Adhesive retaining means can include such things as cold glue, hot melt glue, tape, stickers, labels, band overwrap, shrink overwrap, and the like. In such embodiments,slot 28 is unused until the adhesive retaining means is broken. - The combination of
slot 28 andreclosing edge 26 can generally be referred to as reclosing mechanism. The exact position ofslot 28 on firstfront panel 16 can vary, though it has been found that placement near the apex of thearcuate edge 30 is preferable and can provide a closure that will not readily open by itself when upside down or inverted, when firstfront panel 16 is folded to an acute angle, whencontainer 10 is dropped, or whencontainer 10 is subjected to compressive forces. The folding angle can adjust to accommodate the convex curvature ofcontainer 10. The reclosing mechanism can be configured for a consumer to open using one hand. -
Container 10 can be made from a variety of materials such as a single sheet of foldable material (blank). Preferably,container 10 is made of paperboard of the type conventionally used in food containers or product packages, and more specifically, can be made of 14 point paperboard (approximately 0.3 mm thick). Other materials can include plastic, paperboard-plastic composites, cardboard, fabric, leather, vinyl and the like.Container 10 can additionally include texture on one or more of the surfaces, indicia, or other designs to make the package aesthetically pleasing to consumers. -
FIG. 2 shows the package ofFIG. 1 in an open position.FIG. 2 also shows a plurality ofinternal packets 32, which may contain, for example, powdered or granulated products, such as powdered beverage mix or powdered juice or coffee, salad dressing, instant pudding or gelatin mix, ice cream toppings, desserts and dessert toppings, sprinkles, cookie crumbs, confections such as gum sticks, or other products. - Referring back to
FIG. 2 , in some embodiments, secondfront panel 18 can have at least two layers: aninterior layer 34 and anexterior layer 36, which can be joined at the edges, defining an interior cavity. The edges can be joined by anadhesive layer 68 in a number of manners such as hot melt glue, cold glue, adhesive tape, and the like.Interior layer 34 of secondfront panel 18 defines aninner packet slot 38.Inner packet slot 38 is sized to accommodate at least a portion of one or moreinner packets 32. In one specific example,inner packet 32 is a packet with a powdered drink mix that may be torn open at its upper end.Inner packet 32 may be, for example, two centimeters wide andinner packet slot 38 is at least that wide. - As shown in
FIG. 2 ,inner packet slot 38 can be defined, in part, by an unattached arcuate portion of an edge oflayer 26.Inner packet slot 38 may alternatively be trapezoidal, or may include a tab that can be completely folded under to provide a straight edge under which theinner packet 32 containing product can be slipped. As shown,inner packet slot 38 has ascore line 70 to allow the arcuate portion ofinner packet slot 38 to be bent outwardly forming a tab, thus facilitating easier insertion ofinner packet 32. Additional inner packet slots, such as shown inFIG. 7 , can be optionally provided and allow a consumer to save a plurality of openedinner packets 32 containing e.g., a variety of flavors of powdered beverage within the plurality of slots. The additional inner packet slots can be made by making cuts (arcuate cuts shown) ininterior layer 34. Additionally,score lines 70 can also be added to form outwardly bent tabs as described herein. - After an
inner packet 32 has been opened by tearing its upper end, the upper end may be inserted withininner packet slot 38, betweeninterior layer 34 andexterior layer 36 of secondfront panel 18, as shown inFIG. 3 .Inner packet slot 38 holdsinner packet 32 in place, restricting or eliminating movement thereof. -
FIG. 3B shows that as secondfront panel 18 is acutely folded attop edge 22 to overlap firstfront panel 16,inner packet 32 is also folded, pinching theinner packet 32 closed, thus providing a releasable seal. - Referring now to
FIG. 4 , an example of a blank 42 forcontainer 10 is shown. As shown herein, container blank 42 can be formed from a single sheet of foldable material. Preferably, container blank 42 is made of paperboard of a type conventionally used in food containers, such as 14 point paperboard. Other materials can also be used including plastic, paperboard-plastic composites, cardboard, fabric, leather, vinyl, and the like. Additionally, textures on one or more of the surfaces can be provided in the form of embossing, debossing, coating, and matte or gloss finishing. Indicia or other designs can be provided on container blank 42 so that such indicia or designs are visible on the inside and/or outside ofcontainer 10. - As
FIG. 4 illustrates, container blank 42 includes a back 14, preferably in the shape of a rectangle or square. Length and width of back 14 can be around 10 centimeters to allow for the container to fit into purses, pockets, briefcases, and to be otherwise conveniently sized for transportation. Length and width of back 14 can be greater or smaller, depending on the specific application contemplated, such as may be necessary to accommodate smaller or larger products.Container blank 42 includes two opposingside panels 12, a firstfront panel 16, and a secondfront panel 18 which are adjacent to and integrally connected to the back 14 byfold lines lines FIG. 1 . Further, foldline 44 corresponds totop edge 22 and foldline 46 corresponds tobottom edge 20 ofFIG. 1 . - Referring back to
FIG. 4 , back 14, as illustrated, is larger than the firstfront panel 16, and firstfront panel 16 adjoins back 14 along afold line 46 along the bottom ofback 14. Firstfront panel 16 includes aslot 28 cut through firstfront panel 16 and positioned and shaped to engage reclosingedge 26, or foldline 52 inFIG. 4 of secondfront panel 18. As discussed in connection withFIG. 1 ,slot 28 varies in distance fromfold line 46 depending on the distance offold line 52 fromfold line 44. Firstfront panel 16 includes two arcuate opposingedges 66 to approximately matcharcuate edges 30 ofside panels 12. These opposingedges 66 are adjacent to foldline 46.Edge 62 of firstfront panel 16, which opposes foldline 46, is shown inFIG. 4 as having a hyperbolic shape. Nevertheless, this particular edge can be a straight line, have a trapezoidal cut out, or include other shapes. -
Container blank 42, as illustrated, also includes twoside panels 12.Side panels 12 are divided from back 14 alongfold lines lines Side panels 12 additionally include precisely scoredarcuate edges 30 which define the depth of the package and provide a convex shape to firstfront panel 16. In exemplary embodiments, the distance fromfold line arcuate edge 30 ofside panel 12 is about one centimeter to allow the container to be easily transported in a small purse, bag, or pocket. The distance fromfold line arcuate edge 30 ofside panel 12 varies depending oninner packet 32 to be contained within thecontainer 10. It is this distance fromfold line arcuate edge 30 that gives the package its depth. Furthermore, the distance fromfold line 48 to the apex of thearcuate edge 30 of the associatedside panel 12 is equal to the distance fromfold line 50 to the apex of the correspondingarcuate edge 30 of theside panel 12 associated withfold line 50. - Other features can be provided to
container 10. As shown inFIG. 5 , optionally scored backarcuate edges 72 can further define the depth of the package by providing a second convex shape to back 14. As shown inFIG. 9 , areas ofadhesion 25 can be provided. Preferred adhesives placed in these areas can include hot melt, pressure sensitive, energy activated, and the like.FIG. 9 also shows optional cuts and fold lines to better facilitate product disposed withincontainer 10. As shown,relief score lines lines 33 relieves bowing ofback panel 14 when product is placed therein. -
Side panels 12 can each be connected to anattachment flap 58 along the scored edge using adhesive means described herein. Attachment flaps 58 are folded into the inside of thecontainer 10 when it is assembled and provides a means by which firstfront panel 16 can be joined toside panels 12. Eachattachment flap 58 can have a straight edge 56 opposingarcuate edge 30 and a straight edge 60 adjacent toarcuate edge 30 nearfold line 46. Further, eachattachment flap 58 has a contourededge 54 adjacent to thearcuate edge 30 nearfold line 44. Thisedge 54 is contoured to substantially matchhyperbolic edge 62 of firstfront panel 16 when container blank 42 is folded to form a container. Whencontainer 10 is constructed from container blank 42 as shown inFIG. 4 , attachment flaps 58 can substantially overlap one another. The amount of overlap may vary depending on the desired type and amount of materials to be used and the amount of support desired. Additionally, in exemplary embodiments, attachment flaps 58 can include more than tworelief cuts 64, or fewer than tworelief cuts 64, depending on the type of material selected and its flexibility. -
Container 10 can also include a secondfront panel 18 which, as shown inFIG. 4 , includes at least two layers, anexterior layer 36 and aninterior layer 34 of secondfront panel 18. When shown spread out in the container blank 42,exterior layer 36 andinterior layer 34 are adjacent to and integrally connected to one another by atransverse fold line 52, and substantially form an hourglass shape. As shown inFIG. 4 ,interior layer 34 andexterior layer 36 include partially arcuate edges, although the exact shape of the edges ofinterior layer 34 andexterior layer 36 vary depending on the application and overall shape of thecontainer 10. For example, secondfront panel 18 can be contoured to match the shape of firstfront panel 16, or it can differ in shape from the shape of firstfront panel 16. InFIG. 4 , foldline 52 divides secondfront panel 18 into symmetrical first and second portions, where each portion includes a narrow edge and a wide edge. The first portion, orexterior layer 36, is divided from back 14 along its wide edge, or foldline 44. Foldline 52, located across the narrow part of the secondfront panel 18, comprises reclosingedge 26 inFIG. 1 , and is received byslot 28 of firstfront panel 16 to close the package. - In preferred embodiments, the second portion of the second front panel, or
interior layer 34, includes aninner packet slot 38. When the container blank 42 is folded to createcontainer 10,inner packet slot 38 allows theinterior layer 34 and theexterior layer 36 to be easily separated to receive aninner packet 32 containing product between the two layers.Inner packet slot 38 can vary in size, creating a wider or narrowerinner packet slot 38. As shown inFIG. 4 , inner packet slot can located in approximately the center of the wide edge of the second portion of the second front panel, and has an arcuate shape. As previously discussed,inner packet slot 38 can have other shapes, depending on the specific application contemplated. - To create the
container 10 as shown inFIGS. 1-3 ,slot 28 is cut or scored through firstfront panel 16 of container blank 42 inFIG. 4 .Interior layer 34 is folded down toexterior layer 36 of secondfront panel 18 alongfold line 52 and secured in place. Again, this can be secured using an adhesive means described herein. A portion ofinterior layer 34 andexterior layer 36, including at least the location ofinner packet slot 38, are not joined to allow for receipt of an openinner packet 32 containing product.Container blank 42 is folded alongfold lines Edges 66 of firstfront panel 16 are joined toarcuate edges 30 ofside panels 12, giving firstfront panel 16 an at least partially outward-convex shape. Firstfront panel 16 is joined to attachment flaps 58. Secondfront panel 18 is folded down alongfold line 44 and reclosing edge 26 (foldline 52 inFIG. 4 ) is tucked intoslot 28 on firstfront panel 16 to closecontainer 10. - While preferred embodiments have been described in detail, variations and modifications can be effected within the scope of the embodiments.
