Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a container with a breakable band for accommodating mizuyokan or the like and a method for manufacturing the same.

``Problems to be solved by conventional techniques and inventions'' Canned mizuyokan is well known. In the case of this canned
It has the advantage of being able to directly contain heated and melted mizuyokan, heat sterilization and direct air sealing like other canned goods, and long-term storage.

However, on the other hand, metal cans require high material costs, manufacturing costs, etc., and if a pull ring or other means of opening is used, the manufacturing costs will further increase, resulting in a considerable cost increase, and even worse than the contents. The disadvantage is that the container is much more expensive.

The present invention seeks to eliminate such conventional drawbacks.

"Means for Solving the Problem" The invention of a container with a breakable band as defined in claim 1 provides a synthetic resin container comprising a cup and a lid attached to the mouth of the cup to seal the mouth. The container is characterized in that a break band made of an appropriate synthetic resin, which is made of a material different from the synthetic resin of the main body and can form the container in place of the synthetic resin of the main body, is interposed and integrated as a part of the container into a predetermined opening of the container. shall be.

Further, the invention of the method for manufacturing a container with breakable band in claim 2 provides a method for manufacturing a container with a breakable band in injection molding of a synthetic resin container consisting of a cup and a lid attached to the mouth of the cup to seal the mouth. Forming in advance a breaking band which is made of an appropriate synthetic resin which is different from the synthetic resin of the main body and which can form the container in place of the synthetic resin of the main body, and which is inserted and integrated as a part of the container at the required breaking opening of the container;
A feature of the present invention is that the breakage band is inserted into a proper position during injection molding of a container made of synthetic resin as a main body.

"Function" The container described above can be directly filled with water yokan or the like in a heated molten state and vacuum sealed, and the contents can also be sterilized by heating.

In addition, since the rupture band integrated as part of the container is made of a different material from the main body synthetic resin, the bonding force between the rupture band and the main body synthetic resin is weak, and when force is applied to the rupture band, the boundary with the main body rupture occurs at the
The rupture opening of the container where this rupture zone is located can be opened quickly.

"Example" The drawings illustrate embodiments of the invention.

In the figure, 1 is a cup made of synthetic resin, 2
is a lid made of a synthetic resin sheet, aluminum foil, etc. that is adhered to the mouth of the cup to seal it closed.

The cup 1 is formed by injection molding, and has a peripheral wall 11.
A thin break band 12 is integrally interposed around the top of the cup, and the break band is made of an appropriate synthetic resin that is different from the synthetic resin of the main body of the cup and can be used to mold the cup instead of the synthetic resin of the main body. , for example, one is polyethylene and the other is polypropylene. Of course, the materials listed here are just examples, and various other materials may be used.
It is convenient if both colors are different from each other because they can be easily distinguished.

Furthermore, the rupture zone 12 is formed in advance by injection molding or other appropriate means before the injection molding of the cup 1, and is made slightly longer than the circumference of the circumferential wall 11, and is inserted into the circumferential wall during the injection molding of the cup 1. 11, and the remaining end is used as a knob piece 121 to protrude outward from the peripheral wall.

The mouth of the cup 1 is provided with an outward flange 13 projecting outward from the upper end of the peripheral wall 11, and the lid 2 is attached to the flange 13 by means such as welding after the contents have been accommodated.

With the above structure, the cup 1 is filled with water yokan in a heated and molten state, sterilized by heating, and a lid 2 is attached and sealed in a vacuum.

When opening the package, press the tab 121 of the break band 12.
If you pinch it and pull it around strongly, even if the breakage band 12 and the other parts of the cup 1 are integral, they are made of different materials and the bonding force between them is weak, so a break will occur at the boundary parts a and a. , a tamper opening is obtained.

In addition, in the above-mentioned Example, the content was water yokan, but it may be other than that.

"Effects of the Invention" According to the present invention, it is possible to heat-fill, heat-sterilize, and vacuum-seal mizuyokan and other foods and beverages, and it does not cause spoilage or deterioration even during long-term storage, compared to conventional canned products. It can be used in the same way, and can be obtained at an extremely low cost by insert injection molding of synthetic resin.In addition, when opening the package, all you have to do is pull the tear strip around, no opening tools are required, and opening is extremely easy. The disadvantages of the case can be overcome. Furthermore, it can be arbitrarily used to store various items other than food and drinks.

Claims (1)

[Scope of Claims] 1. In a synthetic resin container consisting of a cup and a lid that is attached to the mouth of the cup to seal the mouth, a container made of a material different from the synthetic resin of the main body is provided at a required breaking opening of the container. A container with a breakable band, characterized in that a breakable band made of an appropriate synthetic resin that can replace the synthetic resin main body to form the container is integrated as part of the container. 2. In injection molding of synthetic resin consisting of a cup and a lid that is attached to the mouth of the cup to seal the mouth, the container is made of a different material from the synthetic resin of the main body of the container and instead of the synthetic resin of the main body. The method is characterized in that a rupture band is formed in advance using an appropriate synthetic resin obtained to intervene and be integrated into the required rupture opening of the container as a part of the container, and the rupture band is inserted at an appropriate position during injection molding of the container using the main body synthetic resin. Method for manufacturing a container with a break band.
