Abstract:
A branch type standing pouch in which an unsealed nozzle can be erected easily
without requiring any special member or process, and the content can be extracted
easily while holding the unsealed nozzle stably. A pouch surface material having
an extraction nozzle backside portion composed of a plastic film and becoming
the extraction nozzle backside when it is folded back and a pouch body surface
portion composed of a plastic film and continuous thereto, a pouch backside material
composing the pouch body backside, an extraction nozzle surface material, and
a bottom member are heat sealed to constitute a branch type standing pouch where
the extraction nozzle is branched from the top of the pouch body. In this pouch,
two nozzle reinforcing surfaces are formed laterally symmetrically on the opposite
sides of a first protrusion by providing, above the center of the pouch surface
material, the first protrusion extending from the center of the extraction nozzle
backside portion over the fold back portion to above the center of the pouch body
surface portion, and two second protrusions laterally symmetrically formed
on the opposite sides of a first protrusion. Furthermore, a third protrusion
extending in the nozzle longitudinal direction is provided in the center of the
extraction nozzle surface material, and a fourth protrusion is provided on the
extension of the third protrusion above the center of the pouch backside material,
whereby a branch type standing pouch is obtained in which the extraction nozzle
can be secured upright at the time of unsealing.
