no. 1 Embodiment approach

[0055] The spout plug 1 and the packaging container 3 according to the first embodiment of the present invention will be described with reference to the drawings.

[0056]

[0057] figure 1 A perspective view of the packaging container 3 is shown. The packaging container 3 has a container main body 100 formed by bending a blank 110 obtained by processing a sheet material 200 described later into a box shape, overlapping and sealing the ends, and a spout plug 1 . The outlet plug 1 has a cap 2 as an example. The container main body 100 includes: a top 101, which becomes the upper part when standing upright; a cylindrical part 102, which becomes the side; and a bottom 103, which becomes the lower part. The fold-in plate 107 and the fold-back plate 108 between the roof panels 106 . A circular spout hole 114 is formed in the roof plate 106a. The outlet plug 1 is installed in the outlet hole 114 . On the top portion 101 , as an example, a weak portion 105 that weakens the br...

Deformed example 2

[0068] Figure 3B In the shown sprue plug, a plurality of ribs 182 are formed in addition to the ribs 181. The ribs 182 are directed from the inside of the flange 15 toward the outside when viewed on the plane of the flange 15, with respect to the lid. 2. The direction opposite to the direction of rotation at the time of screwing extends at an inclination of a second predetermined angle smaller than a right angle. The second predetermined angle is, for example, 60°. As a result, the ribs 182 have a honeycomb structure in which the triangular recesses 17 are arranged in a circumferential shape, so that the flange portion 15 can increase rigidity against loads from directions parallel to the plane including the flange portion 15 .

Abstract

Provided is a pour spout stopper having ample rigidity that remains undamaged by ultrasonic vibration during welding, and is easily separated during disassembly of a packaging container; and a packaging container in which said stopper is used. This pour spout stopper is equipped with a round tubular side wall, and a disk-shaped flange part extending outward from the edge at one end of the side wall. Portions to be cut, which are recessed portions arranged in rings, and ribs provided to ring-shaped protruding portions or to the portions to be cut, are formed in the flange part.

Description

technical field [0001] The present invention relates to a spout plug and a packaging container using it. Background technique [0002] It is known that in the container body settings such as Figure 25 In the packaging container for the spout plug shown, the main body of the container is formed by laminating an aluminum foil, an aluminum vapor-deposited film, or an inorganic oxide vapor-deposited film, etc. The obtained sheet (see Patent Document 1) is bent into a box shape, and the ends are overlapped and sealed. The packaging containers as described above are widely used, for example, as containers for fruit juice drinks, squeezed juices, liquid drinks such as tea, coffee, milk drinks, and soup, and liquors such as Japanese sake and shochu. [0003] There are various forms of the above-mentioned packaging container, and as one of them, it is known to provide a cover made of polyethylene or the like and a spout plug on a gable roof (gable roof type) roof plate. , A packag...
