Abstract
Reclosable gusseted packages or bags have improved resistance to leaking or spilling through the gussets by way of glue or adhesive applied in the gussets in the areas proximate to the reclosable zipper of the bag. This can be done by applying a glue smear to the interior and exterior of the gusset walls; applying glue dots between the exterior facing walls of the gussets; or by applying the glue smear between the exterior facing walls of the gussets.
Description
- 1. Field of the Invention
- The present invention relates to improving the leak-proof or spill-resistant quality of gussets in reclosable packages, particularly those made with multi-wall paper or woven polypropylene.
- 2. Description of the Prior Art
- In the prior art of reclosable packages or bags, it is well known to use gussets between the front and rear walls to increase the capacity of the package or bag with only a small increase in the packaging material, such as multi-wall paper or polypropylene.
- However, the use of gussets can increase the tendency for the contents of the reclosable package or bag to leak from the gusset area proximate to the intersection of the package or bag walls and the zipper. More specifically, the contents can travel up the center of the package or bag, between the zipper profiles and out the gusset.
- It is therefore an object of the present invention to eliminate or reduce the leakage of contents of a gusseted reclosable package or bag through the gussets proximate to the intersection of the zipper profiles and the package or bag walls.
- This and other objects are attained by applying glue or adhesive to the walls of the package or bag within the gusset proximate to the zipper assembly, typically within the gusseted area which is between the zipper flanges.
- Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:
-
FIG. 1 is a plan view, partially in phantom, of a prior art gusseted package or bag, showing the route through which contents may inadvertently escape. -
FIG. 2 is a cross-sectional view along plane 2-2 ofFIG. 1 . -
FIG. 3 is a plan view of the gusseted walls of a reclosable package or bag, prior to application of a zipper assembly, illustrating where the glue or adhesive is applied in an embodiment of the present invention. -
FIG. 4 is a cross-sectional view along plane 4-4 ofFIG. 2 . -
FIG. 5 is a plan view, partially in phantom, of the gusseted package or bag of the present invention. -
FIG. 6 is a plan view, partially in phantom, of a first alternative embodiment of the present invention. -
FIG. 7 is a cross-sectional, partially exploded, view along plane 7-7 ofFIG. 6 . -
FIG. 8 is a cross-sectional view, partially exploded, along plane 8-8 ofFIG. 6 (not including the zipper). -
FIG. 9 is an alternative cross-sectional, partially exploded view, along plane 4-4 ofFIG. 3 , thereby illustrating a second alternative embodiment of the present invention. - Referring now to the drawings in detail wherein like numerals indicate like elements throughout the several views, one sees that
FIG. 1 is a plan view, partially in phantom, of a prior art reclosable package orbag 100 and thatFIG. 2 is a cross-sectional view thereof. The package orbag 100 is formed fromco-extensive front wall 102 andrear wall 104 which are typically formed from polymeric materials (such as, but not limited to, polyethylene or polypropylene, including woven polypropylene), multi-wall paper or laminates. Gussets 106, 108 (illustrated in phantom inFIG. 1 and in cross section inFIG. 2 ) are formed as inwardly pointing folds between the side edges of front andrear walls rear walls gusset walls gusset 108 is formed fromgusset walls rear walls bottom 110.Mouth 112 is formed between the top edges of front andrear walls Zipper assembly 200 is sealed, glued or otherwise secured to the upper exterior of front andrear walls FIG. 7 ,zipper assembly 200 includesfirst profile 202 andsecond profile 204 which are, referring back toFIG. 1 , sealed together atends First profile 202 includesfirst interlocking element 206 andfirst flange 210.Second profile 204 includessecond interlocking element 208 andsecond flange 212. First andsecond flanges rear walls zipper assembly 200 includesslider 214 mounted on first andsecond profiles Slider 214 operates in a conventional manner of interlocking first andsecond interlocking elements second interlocking elements second interlocking elements - As shown by the circuitous path indicated by the arrow in
FIG. 1 , this design is susceptible to contents within package orbag 100 traveling up the center of the package orbag 100, between the first andsecond flanges gussets first gusset 106 but is equally applicable to thesecond gusset 108. - As shown in
FIGS. 3 , 4 and 5, this leakage or spillage can be prevented or minimized by placing a smear of glue oradhesive gussets gusset walls gusset wall 106 a is glued to the interior offront wall 102 and to gussetwall 106 b;gusset wall 106 b is further glued to the interior ofrear wall 104;gusset wall 108 a is glued to the interior offront wall 102 and to gussetwall 108 b; andgusset wall 108 b is further glued to the interior ofrear wall 104. -
FIG. 5 shows, in phantom, gluedareas second profiles areas rear walls second interlocking elements bag 100. An alternative configuration to create the desired gasket effect is to apply glue along the top of thegussets gussets bag 100 so that the glue is urged into the space above the front andrear walls second interlocking elements - In a first alternative embodiment of the present invention, shown in
FIGS. 6 , 7 and 8, a series of glue or adhesive dots 500 (shown in an exaggerated or elongated in the exploded views ofFIGS. 7 and 8 ) is placed betweengusset walls gusset walls - In a second alternative embodiment of the present invention, shown in
FIG. 9 ,glue smear 400′ is placed between the external sides ofgusset walls glue smear 402′ is placed between the external sides ofgusset walls rear walls - The resulting package or
bag 100 has reduced leakage and can be filled, transported and used in the same way as similar packages or bags. - Thus the several aforementioned objects and advantages are most effectively attained. Although preferred embodiments of the invention have been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.
