Bag With Lateral Folds

Abstract

A multi-layer film bag with fusible inner layer has gussets fused to front and rear bag walls. Upper end areas of the gussets are folded over toward one bag wall at a folding line to form folded-over end areas. The folding line is oriented at a slant inwardly and downwardly. The inner side of the folded-over end areas is fused by a first welding seam to an inner side of a neighboring gusset half. The outer side of the folded-over end areas is fused by a second welding seam to a neighboring bag wall. An area of the neighboring gusset half adjoining the folded-over end areas is fused by a third welding seam to a neighboring bag wall. The first, second, and third welding seams form a fused connection closing off the top edges of the folded-over end areas.

1 .- 4 . (canceled) 
   
   
       5 . A gusseted bag comprised of a flexible, multi-layer film having an inner layer that is fusible, the gusseted bag comprising:
 a bottom end that is closed before or after filling with bulk material;   a top end with a closure device;   bag walls forming a front wall of the gusseted bag and a rear wall of the gusseted bag;   gussets inserted at opposed sides between the bag walls and extending from the bottom end to the top end and ending at a spacing below upper edges of the bag walls so that a top area free of the gussets is provided;   wherein the bag walls are fused with the gussets and, in the top area free of the gussets, the bag walls are mutually fused with one another along edges of the bag walls;   wherein upper end areas of the gussets have top edges and are folded over toward one of the bag walls at a folding line and form folded-over end areas, wherein the folding line is oriented in a direction toward the bottom end at a slant inwardly and downwardly;   wherein the folded-over end areas have an inner side that is fused by a first welding seam to an inner side of a neighboring gusset half of the gussets, respectively;   wherein the folded-over end areas have an outer side that is areally fused by a second welding seam to a neighboring bag wall, respectively;   wherein an area of the neighboring gusset half adjoining the folded-over end areas is areally fused by a third welding seam to a neighboring bag wall, respectively;   wherein the first, second, and third welding seams form a fused connection that includes the top edges so that the top edges are closed.   
   
   
       6 . The gusseted bag according to  claim 5 , wherein the end areas are folded over toward the rear wall. 
   
   
       7 . The gusseted bag according to  claim 5 , wherein the closure device is a reclosable closure device that extends at a spacing above the folded-over end areas across an entire bag width of the gusseted bag. 
   
   
       8 . The gusseted bag according to  claim 7 , wherein the reclosable closure device is a three-layer closure strip having outer layers fused to an inner side of the bag walls and having a central layer that is separable by cohesion fracture in two partial layers, wherein the two partial layers, when being placed against one another, are returned into a state of adhesive connection.
