One particular example comprises the storage and dispensing of protein powders in supplement form. Of course, the foregoing is merely exemplary, and the disclosure is not limited to any particular type of material that is to be stored within the standup pouch of the present disclosure. It will be understood that the standup pouch of the present disclosure is not limited to any particular dimension for any panel, any side or any gusset. Indeed, any number of different dimensions are contemplated. - The
standup pouch 10 is formed from a blank 12 which is shown inFIGS. 4 and 5. The blank is defined by a plurality of edges and opposing side faces. In particular, the blank includes a two ply material (the construction of which will be described below in greater detail), which definesouter side face 14 andinner side face 16. The blank, it will be understood with greater specificity below, is a flexible polymer based material. The blank 12 is defined by a plurality of edges, namely,first side edge 20,second side edge 21, firsttop edge 22, and secondtop edge 23. In the embodiment shown, the first side edge and the second side edge are parallel to each other with the first and second top edges being parallel to each other, and perpendicular to the side edges. In turn, the edges define a substantially rectangular blank. Of course, other configurations are likewise contemplated, and the configuration is exemplary solely. - A plurality of folds are disposed along the blank, including, first
lower fold 26, secondlower fold 27 andgusset fold 28. In the configuration shown, thegusset fold 28 is generally positioned at the mid-point between the firsttop edge 22 and the secondtop edge 23, and generally parallel to each one. The firstlower fold 26 and the secondlower fold 27 are spaced apart, generally equally on either side of thegusset fold 28. In the configuration shown, the first and second lower folds 26, 27 are parallel to the gusset fold and spaced apart therefrom a distance that is substantially less than the distance between the respective lower fold and the respective top edge of the blank. For example, whereas the spacing between the gusset fold and a lower fold may be on the order of 60 mm, the spacing between the respective top edge and the lower fold may be on the order of 420 mm. Thus, the lower fold is substantially closer to the gusset fold than to the respective top edge. - A plurality of seals are defined about the first and second lower folds. These form the gusseted portion during assembly when the seals are formed. The seals include first side gusset
outer seal area 30 and first side gussetinner seal area 31. The two first side gusset seal areas are generally symmetrical structures that are mirror images of each other about the firstlower fold 26. In the configuration shown, each of the first side gusset seal areas combine to form an hourglass shape which is symmetrical about a midpoint between the first and second side edges 20, 21. In other configurations, the first side gusset seal areas may comprise a plurality of discrete seal areas that are discontinuous, that is, a portion of the first lower fold may be free of any seal structure. The particular configuration of the seals can be varied. It will be understood that the configuration of the seals imparts different strength characteristics to the overall pouch, and also provides for a different standup configuration, among other differences. Examples of different configurations of the gusset seals is shown inFIGS. 6 a through 6 c. It will be understood that these are exemplary, and not intended to be limiting. - A substantially identical configuration of gusset seals are formed about the second
lower fold 27. These seal areas comprise second side gussetouter seal area 32 and second side gussetinner seal area 33. The two gusset seal areas are mirror images of each other about the secondlower fold 27. The shape of the second side gusset seal areas is substantially identical to the first side gusset seal areas in the configuration shown. Of course, these may be modified so as not to be substantially identical. Additionally, certain voids, such as voids may be present in the seal structures, that is areas that are configured to not be sealed together. - Spaced apart from the first
top edge 22 is a firstzipper element assembly 36, and spaced apart from the secondtop edge 23 is a secondzipper element assembly 37. The two zipper elements cooperate to form a resealable sealing assembly which, when the bag is formed, can selectively seal the contents of the standup pouch. The zipper elements are spaced apart from the respective top edge a predetermined distance such that a grasping region and a sealing region exists between the zipper element and the respective top edge. A rip indent, such as first rip indent 50 a may be defined along thefirst side edge 20. Other rip indents 50 b, 52 a, 52 b, can be dispersed about the blank in a similar position along the side edges between the respective zipper element and the respective top edge. It will be understood that when the bag is formed, the user can rip the top portion of the bag by initiating the rip at the rip indent, to eventually create an opening at the top of the pouch and to gain access to the zipper element assembly. Of course, other methods of providing for the removal of this portion, such as scoring, or perforating is likewise contemplated. It will be understand that the zipper elements are substantially parallel to the top edges and generally perpendicular to the first and second side edges. It is likewise contemplated that the dipper elements may be eliminated from certain configurations. - The various folds, edges and elements define several regions of the blank. In particular, a first handle portion 40, a
front panel portion 42, afirst gusset panel 43, asecond gusset panel 44, aback panel 46 and asecond handle portion 47. The first handle portion is bound by the firsttop edge 22 and the firstzipper element assembly 36 as well as by the first and second side edges 20, 21, to, in turn, define a generally rectangular configuration. Thefront panel portion 42 is defined by the first zipper element at one end and the first lower fold at the other end, and the side edges on either side thereof. Thefirst gusset panel 43 is defined by the firstlower fold 26 and thegusset fold 28, as well as by the side edges on either side thereof. Thesecond gusset panel 44 is defined by thegusset fold 28 and the secondlower fold 27, as well as by the side edges. Theback panel 46 is defined by the secondlower fold 27 and the secondzipper element assembly 37 as well as by the side edges. The second handle portion is defined by the secondtop edge 23 and the secondzipper element assembly 37 and by the side edges. - In the configuration shown, there are symmetries about the blank. That is, the first gusset panel and the second gusset panel are substantially mirror images of each other about the
gusset fold 28. Similarly, the front panel and the back panel are substantially mirror images of each other about thegusset fold 28. The first and second handle portions are substantially mirror images of each other about thegusset fold 28. It will further be understood that the rip indents 50 a, 52 a are configured to match upon formation of the pouch, as arerip indents 50 b, 52 b. - In addition, a tabbed portion can be removed from each of the first side gusset
inner seal area 31 and the second side gussetinner seal area 33 along both thefirst side edge 20 and thesecond side edge 21 to formslots 53 a, 53 b and 54 a, 54 b. Additionally, the inner ply can be removed from an additional tabbed portions (leaving only the outer ply), to form slot regions 55 a, 55 b and 56 a, 56 b. It will be explained below that these slot regions allow for the inner surface of the first ply in the first side gusset outer seal area to be sealed to the second side gusset outer seal area. - The blank is shown in
FIG. 4 from the outer side face (which is the outside of the first ply) and inFIG. 5 from the inner side face (which is the inside of the second ply). Each ply is substantially identical in configuration, however, in certain areas, the portions of either ply may be missing. Additionally, there may be some differences in dimension between each ply. - The formed bag is shown in
FIGS. 1 through 3 as comprising the front 60, the back 62 and thegusset region 64. More particularly, the bag is folded in a gusseted manner such that the firstlower fold 26 and the secondlower fold 27 form the bottom of the standup pouch and the first and secondtop edges first gusset seal 70 is formed about the first side gusset seal area, and mated with the side seals 66, 68. Similarly, thesecond gusset seal 72 is formed about the second side gusset seal area, and mated with the side seals 66, 68. It will be understood that the gusset seals and the side seals meet at a region proximate to either side edge. Such a configuration defines a substantially fluid tight cavity therebetween. - Additionally, a seal extends across the top edges between the side edges. Such a top seal may be of varying thickness between the top edge and the zipper element assembly. It will be understood that openings, or handle regions may be extended through such a seal region, if desired.
- The formed gussets are joined together at each of the
slots 53 a, 53 b and 54 a, 54 b. Thus, while the gusset allows for the spreading of the firstlower fold 26 relative to the secondlower fold 27, the joining about the foregoing slots, provides a controlled relative movement of the gussets relative to each other. - With reference to
FIG. 7 , the standup pouch of the present disclosure is formed from a multiple ply configuration comprising afirst ply 100 and the second ply 102. The first ply comprises a plural of layers that are laminated (through adhesive layers and/or heat) to each other. In particular, the first ply comprises anouter layer 110, a print layer 112, anadhesive layer 114, a central layer 116, a second adhesive layer 118 and aninner layer 120. Theadhesive layer 114 and the second adhesive layer 118 couple the outer layer (and the print layer which is applied thereto), the central layer and the inner layer to each other. Theouter layer 110 comprises a Matte OPP or a PET material. The central layer 116 comprises a MET PET or a cavitated OPP material. The inner layer comprises a PE material or a coextruded multilayer film. - In the configuration shown, the inner layer comprises a coextruded multilayer film that includes five separate layers, a
first layer 130, asecond layer 132, athird layer 134, a fourth layer 136 and a fifth layer 138. In the configuration shown, the second and fourth layers comprise a tie layer. Thefirst layer 130 and the fifth layer 138 each comprise a PE layer. The third layer comprises a nylon layer. While such a configuration has shown improved durability, especially through drop testing, it is understood that this multilayer film may be replaced with a single or multilayer film comprising PE. - Of course, these formulations of the different layers are exemplary, and utilized in the configuration shown. It will be understood that variations may be contemplated with the formulations that are utilized in the different layers. It will also be understood that the blank and each ply may be formed from a number of different films that are coupled together in an end to end fashion or a side to side fashion. That is, the front and the back may be formed from different films, and these films may be different than the films from which the gusset is formed. In addition, the gusset may be formed from a plurality of films, as may each of the back and front. The films may be similar or distinct. In addition, it will be understood that the same coupling of different films may be present with both the first ply and the second ply. It will also be understood that each panel may be formed from multiple different films that are coupled together.
- In the configuration shown, the first ply and the second ply are coupled together (that is, welded together through different means, RF, heat, sonic, etc.) along the various seals, and along the zipper element assembly.
- It has been found that a single ply standup pouch of varying construction, including the construction of the first ply has difficult maintaining integrity when drop tests are executed from a height of 0.5 meters. As such, the pouch is susceptible to damage (i.e., leaking, contamination, etc.) during shipping, displaying, or during use by a user. It has been found that the two ply structure of the present disclosure, is capable of easily surviving drop tests at the height of 0.5 meters. It has been additionally found that the two ply structure of the present disclosure is capable of surviving drops from two times that height (or 1.0 meter), and for drops up to 2.5 meters and, depending on the configuration, therebeyond. As a result, the standup pouch of the present disclosure has a greatly increased ability to survive without a loss of integrity, during shipping, display and use.
- The foregoing description merely explains and illustrates the invention and the invention is not limited thereto except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications without departing from the scope of the invention.
