SIDE-GUSSET BAG AND METHOD OF MAKING A SIDE-GUSSET BAG

摘要

A bag has front and back face panels having upright longitudinally extending side edges and transversely extending upper and lower edges. First and second gusset panels each have transversely extending upper and lower edges and upright longitudinal outer edges connected to the longitudinal edges of the face panels. A reclosable fastener strip extends continuously and transversely along the first gusset panel and inward along each of the face panels from the first gusset panel along part of a transverse width of the face panels. Thus opening of the fastener and folding out of the first gusset panel forms a spout on the bag. A separate generally rectangular floor panel is joined at its outer edge by thermal welds to the lower edges of the face panels and of the gusset panels.

1. A bag comprising:
front and back face panels having upright longitudinally extending side edges and transversely extending upper and lower edges; first and second gusset panels each having transversely extending upper and lower edges and upright longitudinal outer edges connected to the longitudinal edges of the face panels; a reclosable fastener strip extending transversely along the first gusset panel and inward along each of the face panels from the first gusset panel along part of a transverse width of the face panels, whereby opening of the fastener and folding out of the first gusset panel forms a spout on the bag; a separate generally rectangular floor panel; and thermal welds joining the lower edges of the face panels and of the gusset panels to outer edges of the floor panel.
