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.
