Bag and zipper assembly with secured side gussets

1. A bag and zipper assembly, comprising:

side gussets of the bag between first and second panels;

each side gusset having a first side section joined by a first fold to the first panel, and a second side section joined by a second fold to the second panel and a third fold along which the first side section and the second side section are folded;

a set of one or more gusset openings solely in the first side section of each side gusset adjacent an open end of the bag;

a corresponding set of one or more panel openings solely in the first panel adjacent said open end of the bag; and

adhesive in each of the one or more gusset openings adhering together the first side section and the second side section of each side gusset;

said adhesive extending in the one or more panel openings solely in the first panel, and said adhesive adhering the first side sections of the side gussets to the first panel wherein said adhesive restrains each side gusset from movement outwardly from between the first and second panels adjacent said open end of the bag, and wherein the second panel and the second side sections of the side gussets unfold along the second folds to expand the bag interior adjacent said open end of the bag;

said adhesive combining with additional adhesive adhering the first panel to a first zipper flange of the zipper assembly; and

the second panel of the bag being adhered by further adhesive to a second zipper flange of the zipper assembly.

2. The assembly of claim 1 wherein the one or more gusset openings are through a side gusset within an inner extremity and an outer extremity of the first section of the side gusset.

3. The assembly of claim 1 wherein for each side gusset, one of the one or more gusset openings extends through an outer extremity of the first side section of the side gusset, and the zipper flanges extend beyond the outer extremity and cover the one or more gusset openings.

4. A method of making a bag and a zipper assembly, comprising:

penetrating through each side gusset of a bag adjacent an open end of a bag to provide a set of one or more gusset openings solely in a first side section of each side gusset foldably connected to a first panel and a second panel;

penetrating through the first panel to provide a corresponding set of one or more panel openings solely through the first panel adjacent said open end of the bag;

applying adhesive in each of the one or more gusset openings and adhering together the first side section and a second side section of each side gusset adjacent said open end of the bag, and extending the adhesive in the one or more panel openings for the adhesive to adhere the side gussets to the first panel adjacent the open end of the bag and restrain each side gusset from movement outwardly from between the first and second panels, wherein the second panel and the second side sections of the side gussets unfold along the second folds to expand the bag interior adjacent said open end of the bag;

combining the adhesive with additional adhesive adhering the first panel to a first zipper flange of the zipper assembly; and

adhering the second panel of the bag by further adhesive to a second zipper flange of the zipper assembly.

5. The method of claim 4 wherein the one or more gusset openings are within an inner extremity and an outer extremity of the side gusset.

6. The method of claim 4 further comprising:

for each side gusset, extending one of the one or more gusset openings beyond an outer extremity of the side gusset, and

extending the zipper flanges beyond the outer extremity and covering the one or more gusset openings.
