JPH11147562A - Shape for stabilizing unsealing of packaging bag seal-processed using sheet or cylindrical material such as waterproof paper, vinyl film or aluminum foil - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate stable support and cutting at the time of unsealing of a packaging pack which is seal-processed by using a sheet or cylindrical material such as waterproof paper, vinyl film or aluminum foil. SOLUTION: (A) A side of a packaging pack is not stuck but instead a crease of a packaging material is utilized to provide a side as indicated by a numeral 2. (B) A cut is made with a side adjacent to it as a sticking face to provide a lead for tearing at the time of unsealing the pack wherein sticking is made so that an internal angle of the sticking face is an acute angle with respect to a side of the crease 2 as indicated by a numeral 4. (C) When the pack is torn off from the cut at the time of unsealing, the cut is located so that a tear comes across the acute-angled part. In addition, a size of an unsealing port can be adjusted in an amount to be taken out by shifting a position of the cut as indicated by a numeral 5 or 5'.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention is mainly used as a packaging method for distribution of foods, cosmetics, medicines and the like.

[0002]

2. Description of the Related Art At present, packaging packs made of vinyl films for foods, cosmetics, chemicals, etc., which are currently being distributed, are generally heated and sealed with high frequency around the packaging pack, and simply cut into the periphery. It is common to tear open from there.

[0003]

This has the following disadvantages. (B) At the time of opening, it is impossible to predict in which direction the rift will run and how large the cut will be, so that control cannot be performed. (B) Particularly, the contents pop out unexpectedly due to the recoil at the time of tearing, or a part of the cut edge that has not been completely torn off resists the outflow of the contents and comes out in the opposite direction and contaminates the finger, and is opened. Sometimes very nervous. (C) For elderly people or children with weak supporting fingers,
It is hard to open. (D) Depending on the contents, it may even be dangerous.

[0004]

Means for Solving the Problems The position of the packaging pack at the time of opening is determined in a mutual relationship as 1234567, so that the opening operation is stabilized.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION

(A) One side of the packaging pack body is not bonded, but is made to be one side using the fold of the packaging material as shown in 2 in the figure. (B) A cut is made using one side adjacent to the adhesive surface as a bonding surface, and the opening is used as a clue for tearing when the pack is opened. At this time, the angle of the inner side of the bonding surface with respect to one side of the bent portion 2 in FIG. Glue to form an acute angle. (C) When tearing from the cut portion when opening the pack, the position of the cut (5 in the figure) is determined so that the position of the tear crosses the acute angle portion. Also, the size of the opening can be adjusted by shifting the position of the cutout as indicated by 5 or 5 'in the figure, so that the amount of contents to be taken out can be adjusted.

[0006]

【The invention's effect】

(B) Compared to the force of tearing the adhesive part of the packaging material, the force of tearing the bent part is naturally small, so it is possible to tear at a stretch with the first force, and at the same time it is easily stable because there is an acute angle on the tearing line Can be opened. (B) At this time, the opening of the main body of the packaging pack always faces upward. (C) Since the base of the sharp corner is always held down for supporting, the contents do not jump out. It has a shape that cannot be torn apart from this position. (D) Since the shape of the opening is naturally leaky, the contents can be smoothly taken out. It is easy to handle for people with weak fingers, especially elderly people, children, single travelers and travelers. (E) Depending on the thickness of the film, it can be used for a film having a large content, which is useful for reducing distribution costs.
