Document Type and Number:
WIPO Patent Application WO/2020/250792
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a pouch and a content liquid containing pouch that make it possible to emit a perfume ingredient contained in a content liquid to an outside without unsealing the pouch while avoiding leakage of the liquid content (content liquid) to the outside or degradation in quality with a simple configuration, and that have high resistance to breakage of a bag due to dropping. A pouch (10) is formed in a bag shape by an outer peripheral seal part (20) to which a film (11) is thermally bonded, and accommodates a content liquid in an accommodation part (30). A perfume ingredient emission part (40) is formed at a position corresponding to the accommodation part on at least one side of the film. The perfume ingredient emission part is constituted by a material removing part (41) or a cut-shaped score formed in a partial range in a thickness direction of the film. In a perfume ingredient emission area, the film has a tensile strength of 90 N/50 mm or more in a pouch width direction and a tensile strength of 125 N/50 mm or more in a pouch height direction.
