Benefits of technology

[0007] The object of the present invention is to provide an improved container of the known type to impart to the container inherent strength that counteracts upsetting or folding of its connecting portion and side walls.

Problems solved by technology

The wrinkle affects the shape and appearance of the container in a negative fashion and, if the worst comes to the worst, causes wear on the side walls and a notch with a risk of leakage.
Such a duct certainly provides a good, three-dimensional handle but does not contribute to the stiffness or stability of the container.
The gas-filled duct rather causes an increased risk of wrinkling.

Embodiment Construction

[0010] These and other objects, which will be evident from the following description, are now achieved by a container comprising a compartment which is defined by flexible walls and whose volume depends on the relative position of the walls, two opposite side walls being joined along a common connecting portion, characterised in that a first gas-filled duct means is arranged in the connecting portion along at least a first side of the container.

[0011] As a result, the first gas-filled duct means forms a kind of backbone in the container which gives stiffness and stability in each side of the container in which the gas-filled duct means is arranged. This counteracts the container losing shape and appearance during transport or careless handling. Moreover, the risk of notches by wrinkle-related wear is reduced. By arranging the stiffening in the form of a gas-filled duct means, no new type of material or no further amount of material is added. The inventive container can thus be intro...

Abstract

A container (1) comprising a compartment (4) which is defined by flexible walls and whose volume depends on the relative position of the walls, two opposite side walls (2) being joined along a common connecting portion (5). The container is characterised in that a first gas-filled duct means (11) is arranged in the connecting portion (5) along at least a first side (12) of the container (1). The invention also concerns a method of producing such a container by forming at least one gap in said side walls (2) in connection with the forming of the connecting portion (5) and, in connection with the filling of the container (1), filling each gap with gas and sealing it to form a gas-filled duct (11, 16, 18).

Description

[0001] The present invention relates to a container of a collapsible type, more specifically such a container comprising a compartment which is defined by flexible walls and whose volume depends on the relative position of the walls, two opposite side walls being joined along a common connecting portion, and a method of producing the same.[0002] A container of the type described by way of introduction is known from e.g. WO9941155 which discloses a container of a collapsible type comprising three wall portions, of which two form opposite side walls and a third one forms a bottom wall. The walls which are made of a plastic material are flexible and interconnected to form a compartment whose volume depends on the relative position of the walls. The container has a carrying means which is integrated with the connecting portion and comprises openings to form a handle.[0003] In the transition between the upper and the lower portion of the container, i.e. between the lower edge of the carr...
