POURING SPOUT FOR CONTAINER AND CONTAINER WITH POURING SPOUT
Document Type and Number:
WIPO Patent Application WO/2005/108228
Kind Code:
A1
Abstract:
A pouring spout for container is made of thermosetting plastic and has a to-be-sealed surface at the opening of a bag-like container body made of a laminated film having a barrier layer and an innermost sealant layer. A protrusion and recess section is formed and distributed on the entire surface of the to-be-sealed surface, and differences in height in the protrusion and recess section are set smaller than the thickness of the sealant layer. With such a pouring spout, high adhesion to the opening of the container body is attained, ensuring excellent sealing ability, and damage to the barrier layer of the laminate film can be reduced or eliminated during or after heat-sealing, so that barrier properties of the laminate film is not impaired.
