Paper package and straw

Abstract

A person thrusts a straw into a press-foldable paper package (20) through an insertion section (36) formed in the top thereof, whereupon he or she can pressingly fold the package flat from outside so as to press out the contents for drinking. The top and bottom of the package are bent flat, and triangular projections (21) disposed in the top and projection left and right are bent downward and are weakly adhesively bonded to the lateral surfaces (25) of the package by thermal processing. Disposed below the opposite surfaces (25) of the package are an inverted V-shaped fold (27) in a triangle surface with their bottoms (24) on the bottom side, and vertical folds (29) extending vertically upward from the vertexes (28). The lateral surface (25) of the package can be folded flat by folding the vertical folds (29) and inverted V-shaped folds (27). A first horizontal fold (31) and a second horizontal fold (34) are disposed below and above the front surface (30), respectively, to allow the front half of the upper surface and the front half of the bottom surface to be folded flat onto the front surface (30).

Description

TECHNICAL FIELD [0001] This invention relates to a press-deformable paper package and a straw wherein contents of juice, refreshing drinks, particularly, jelly food and the like contained in a paper package are drinkable by an external pressure without using a sucking force. BACKGROUND ART [0002] As illustrated in FIG. 16, a paper package 1 containing various kinds of refreshing drinks such as milk, a refreshing drink, juice and the like has an insertion section 2 into which a straw 3 is thrust in a top surface section 9 of the package to drink various kinds of refreshing drinks therein to allow drinking from an upper end of the straw whose tip end is thrust into a sealed film covering the insertion section. Unexamined Japanese Patent Publication 2000-313435 discloses such straw 3 which has a tip end that is obliquely shaped to be easily thrust into the insertion section 2 and which is attached to an outer surface of the package in a state that it is contained in a transparent bag 5...

AI Technical Summary

Benefits of technology

[0028] The present invention is the paper package and straw which includes a foldable package and viscous fluid and which facilitates the flow of contents, and since the contents of the press-deformable package are drunk, even if a person does not suck the straw thrust into the insertion section of the package or cannot suck the straw, guiding folds are formed to fold the package flat and the package is pressed from

Problems solved by technology

However, in the case of the contents of viscous liquid having viscosity such as a jelly drink rather than a solution such as a refreshing drink, a strong sucking force is required to drink them through the straw.

For this reason, it was difficult for persons such as infants, sick persons, old persons, who were too weak physical
