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.
Claims26
A pouch comprising:
- a pouch body having a top part and a bottom part;
- and
- a branched chamber extending outwardly from a side wall of the pouch body at a location proximal to the top part with respect to the bottom part, the branched chamber having a pouring spout defined at a distal end thereof and an entrance is formed from the pouch body into the branched chamber, the branched chamber having a valve member disposed therein for defining a quantitative cell within the branched chamber, the valve member having a feature that provides selective communication between the pouch body and the quantitative cell so that contents can flow into and be held within the quantitative cell, wherein a first section of the valve member is attached to a first side wall of the branched chamber and a second section of the valve member is attached to a second side wall of the branched chamber.
A pouch comprising:
- a pouch body having a first end and a second end;
- and
- a branched chamber extending outwardly from a side wall of the pouch body at a location proximal to the first end of the pouch body with an entrance being formed from the pouch body into the branched chamber, the branched chamber having a pouring spout defined at a distal end thereof, the branched chamber having a valve member disposed therein for defining a quantitative cell within the branched chamber, the valve member being arranged so that selective communication is provided between the pouch body and the quantitative cell such that contents can flow from the pouch body into the quantitative cell where they are held therein, wherein a first section of the valve member is attached to a first side wall of the branched chamber and a second section of the valve member is attached to a second side wall of the branched chamber.
