Abstract
At least one branched chamber extends and diverges from a side wall of a pouch body. The branched chamber has an optional pouring spout at its distal end to permit the removal of the contents of the pouch. A readily unsealable seal member is optionally included to partition the branched chamber from the pouch body, thus providing a pouch wherein two or more different materials are mixed prior to removal from the pouch. A pouch having this structure provides excellent rupture protection of the readily unsealable seal member caused from, for example, handling, shipping, or dropping of the pouch.
Claims6
A self-standing pouch comprising:
- a pouch body having a top part and a bottom gusset that permits the pouch body to be a self-standing body;
- and
- at least one branched chamber extending outwardly from substantially an entire width of a side wall of the pouch body at a location proximal to the top part with respect to the bottom part, wherein a pressure absorbing space is formed between the top part and a location where the at least one branched chamber extends from the side wall, the at least one branched chamber having a pouring spout formed at a distal end thereof and a tearable tab closes the pouring spout, wherein the at least one branched chamber is stored folded along one side wall of the pouch body to prevent pouch contents from unintentionally flowing into the at least one branched chamber from the pouch body.
