Abstract

PROBLEM TO BE SOLVED: To accurately, beautifully cut and unseal a pouch open straight by providing a perforation or a score at a content stowing part so that the perforation or score runs across a part of a corner and upper and vertical seals. SOLUTION: Plastic films or laminate films of plastic film and paper are heat-sealed to form a square, rectangular or lozenge-shaped sealed pouch package 1. A content-stowing part 4 is formed by a top seal 2, a bottom seal 2' and vertical seals 3. An opening perforation or score 6 is provided across a corner 5 that is formed by the top seal 2 and the vertical seal 3. Therefore, the pouch package 1 can be smoothly torn open straight along the perforation or score 6 because the film of the pouch package 1 is torn without opposing the stretched direction of the film. As a result, such a problem that contents are hardly taken out because of a small opening is solved, and the contents are prevented from leaking when the film of the pouch is torn off.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealed pouch package made of a plastic film or a laminated film.

[0002]

2. Description of the Related Art A conventional hermetically sealed package having a diamond-shaped bag or a hermetically sealed package provided with a bottle-shaped discharge portion (pour-out portion) (for example, Japanese Utility Model Publication No. 50-406).
No. 91) is known. When the contents (liquid, powder, etc.) are taken out, the rhombus-shaped hermetically sealed package is cut away in a slanting direction from the rhombus acute angle portion to form a spout for facilitating the extraction of the contents. , The contents were taken out from the said section, and
According to the '0691 publication, a vertically long rectangular parallelepiped hermetically sealed package is provided with a vertically long bottle-shaped liquid container, and the bottle-like portion of the liquid container is cut out from a notch to form a spout. The contents were taken out from the section.

[0003]

However, the film generally used for this kind of hermetically sealed package has a stretching direction in the longitudinal and transverse directions, and in the case of the above-mentioned prior art, both of the above-mentioned prior arts are torn the film when opening. The film is difficult to cut because it is performed diagonally with respect to the longitudinal and horizontal stretching directions.
And it becomes unstable, and as a result, it is not opened correctly,
A spout (opening) where the cut is cut linearly and neatly
There is a problem in that a sealed package having the above can not be obtained. In particular, in the case of a small bag such as a small bag sealed package, in addition to the above problems, there is a problem that the opening is small and it is difficult to take out the contents, and the contents spill when severing the film. There was a problem that it came out.

[0004]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and in a square type sealed pouch package, the contents storage portion is a square type, a rectangular type or a rhombus type, Further, a broken line or a notch for opening one corner portion of the contents storage portion is provided so as to cross the one corner portion over the upper side seal portion and the vertical seal portion, and the upper side seal portion and the vertical seal portion are integrally continuous. In the upper corner portion to be provided with a contents container having a bottle-shaped discharge part, a broken line or a notch for opening the bottle-shaped discharge part of the contents container,
It is characterized in that it is provided so as to cross the bottle-shaped discharge portion over the upper side seal portion and the vertical seal portion.

[0005]

1 and 2 show an embodiment of the present invention, in which FIG. 1 (a) is a rectangular or rectangular shape for the contents storage portion, and FIG. 1 (b) is a diamond shape. 2A, 2B, 2C, 2D, 2C, 2D, and 2D, the front view of the sealed pouch package in the case of
(E), (f) is a front view of a sealed pouch package in the case where the content container is a bottle type.

In FIGS. 1 (a) and 1 (b), reference numeral 1 designates a rectangular, rectangular or rhomboidal sealed pouch package, which is a well-known plastic film or a laminated film of plastic film or a plastic film and paper and the like. It is formed by heat-sealing the laminated film. 2 is an upper side seal part of the rectangular, rectangular or rhombic sealed pouch package 1, 2'is a lower side seal part, and 3 is a vertical seal part. 4 is the sealed pouch package 1
In FIG. 5, the content storage portion 5 is a corner portion where the upper side seal portion 2 and the vertical seal portion 3 are integrally continuous, and 6 is a broken line or notch for opening the one side portion, and the upper side seal portion is formed so as to cross the corner portion. 2 and the vertical seal portion 3 are provided.

Reference numeral 7 is a bottle-shaped contents accommodating portion formed by arranging a bottle-shaped discharge portion 9 at an upper corner portion 8 where the upper side seal portion 2 and the vertical seal portion 3 are integrally continuous. Reference numeral 10 is a broken line or a notch for opening the bottle-shaped discharge portion, and the upper side seal portion 2 and the vertical seal portion 3 are arranged so as to cross the bottle-shaped discharge portion 9.
It is provided over. Although the sealed pouch package 1 in this embodiment is a three-side sealed type, it is not limited to this.

[0008]

EFFECTS OF THE INVENTION According to the present invention, in a square type sealed pouch package, the contents accommodating portion is formed into a rectangular shape, a rectangular shape or a rhombic shape, and the contents accommodating portion is opened at one corner. A broken line or a cut is provided across the upper side seal part and the vertical seal part so as to cross the corner part, and a bottle-shaped discharge part is provided at the upper corner part where the upper side seal part and the vertical seal part are integrally continuous. And a broken line or a notch for opening the bottle-shaped discharge part of the contents storage part, so that the bottle-shaped discharge part is crossed over the upper side seal part and the vertical seal part. Since it is provided, even in the case of a sealed pouch package in which the form of the entire bag is quite small, over the upper side seal part and the vertical seal part of the sealed pouch package,
A smooth opening can be made linearly without disturbing the stretching direction of the film by a broken line or a notch provided so as to cross the discharge port of the contents, and as a result, the conventional sealed pouch package of this kind It was a neck, difficult to cut, difficult to put out, small opening,
There is an effect that problems such as spilling of contents at the time of opening can be solved all at once.
