Abstract

A side gusset paper container in which in the region of the transition of the front wall to a first part of the container bottom region, there is a first pre-crease, and in which in the region of the transition of the rear wall into a second part of the container bottom region, there is a second pre-crease. Furthermore, the disclosure relates to a method for producing a side gusset paper container, in which at least one or a plurality of linear pre-creases are formed in the inner side of a paper web. Additionally, the disclosure relates to a use of the side gusset paper container according to the disclosure as a compost collecting and/or carrying container and/or as a fillable container which is self-standing in the unfilled state.

Claims25

Dependent claims

A side gusset paper container, comprising:

a container bottom region,
a front wall with an upper container edge and an inner and outer container side and opposite longitudinal folding edges,
a rear wall with an upper container edge and an inner and outer container side and opposite longitudinal folding edges,
opposite first and second side walls, each with an upper container edge and an inner and outer container side, each containing at least one side gusset,
wherein the front wall, in particular along a first folding edge, transitions in one piece into a first part of the container bottom region with a first outer edge,
wherein the rear wall, in particular along a second folding edge, transitions in one piece with a second part of the container bottom region with a second outer edge, and
wherein:
in the region of the transition of the front wall to the first part of the container bottom region, in particular in the region of the first folding edge or on the first folding edge, at least partially, in particular fully, there is a first pre-crease, and
in the region of the transition of the rear wall into the second part of the container bottom region, in particular in the region of the second folding edge or on the second folding edge, at least partially, in particular fully, there is a second pre-crease.

6 more elements

A method for producing a side gusset paper container, comprising:

providing an, in particular continuous, a paper web having an inner and outer side and having a first side edge and an opposite second side edge and also a longitudinal extension,
providing an embossing tool,
providing a perforation tool,
transferring at least a part of the paper web onto a substantially planar, in particular substantially non-yielding base, so that the outer side faces the base,
introducing at least one linear pre-crease extending substantially from the first to the second side edge or from the first to the second side edge, in particular continuously, in particular at a right angle or substantially at a right angle to the longitudinal extension of the paper web, into the inner side of the paper web with the embossing tool,
if necessary attaching a first and/or second carrier handle, in particular to the inner side of the paper web at a distance from the linear pre-crease,
providing a first perforation line extending from the first to the second side edge, in particular continuously, without causing any separation, and
providing a second perforation line extending from the first to the second side edge, in particular continuously, without causing any separation, at a distance from the first perforation line, forming a blank base shape for the side gusset paper container, wherein the linear pre-crease is closer to the first perforation line than the second.
