BOTTOM-GUSSETED PACKAGE AND METHOD

摘要

A bottom-gusseted package comprises a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package.

主权项

1. A method of making bottom-gusseted packages, comprising the steps of:
providing a flexible web of material having a longitudinal axis, providing a flexible, sleeve-forming web; cutting said flexible, sleeve-forming web into a plurality of individual sleeves; joining said individual sleeves to said flexible web in spaced apart relationship longitudinally of said flexible web, with the spacing between said individual sleeves corresponding to the length of each of said bottom-gusseted packages being formed; folding said flexible web of material and joining the lateral margins thereof to form a folded flexible web, and to thereby form a package body for each of said bottom-gusseted packages, each package body including a front package panel and a rear package panel joined at opposite side margins thereof, said individual sleeves being positioned generally within said folded flexible web; and cutting said folded flexible web at intervals each corresponding in length to said length of each of said bottom-gusseted packages, so each individual sleeve provides a bottom gusset for a respective one of the packages being formed.
