Description

[Detailed Description of the Invention] [Industrial field of application] The present invention encloses and seals liquids such as shampoo and rinse in shampoo sets for instant foods, liquids or powders, or an appropriate gas, and a container at the seal portion. The present invention relates to a container in which the contents are taken out by rupturing the container and made disposable.

[Conventional technology]

In the conventional container as described above, a notch for opening guide is usually provided in the seal portion, and the container is torn from the notch to take out the contents.

[Problems to be solved by the device]

However, many of the conventional containers mentioned above are not easy to tear from the cuts, so the contents are scattered at the time of tearing and the clothes etc. are soiled. Since it often enters inside, it is not hygienic, and there is a problem that clothes and the like are soiled by the contents attached to the above-mentioned fragments.

Therefore, the problem to be solved by the present invention is to provide a disposable container which is easy to open and does not have the above problems.

[Means for Solving the Problems]

The present invention has been made for the purpose of solving the above-mentioned problems, and its constitution is a disposable container made of a uniaxially stretched synthetic resin film for enclosing a liquid, a granular material or the like and sealing both ends. Provided in the easy tear direction, the seal shape on the side where the contents are to be discharged has a shape with an elongated protrusion inside, and by pressing the body of the container, stress is concentrated on the elongated protrusion, and the elongated protrusion is formed. It is characterized in that the container is torn at the part.

[Function of device]

In the disposable container of the present invention, the seal portion is provided in the easy tearing direction,
Since the seal on the side where the contents are to be discharged has a shape with an elongated protrusion inside, if the body of the container filled with contents is pressed, stress concentrates on the elongated protrusion and the tip The container is torn from the part, the entire side of the elongated protrusion is torn,
The contents flow out without scattering.

The material used in the present invention is a synthetic resin film that can be heat-welded or ultrasonically welded and has a thickness of 50-100 μm.
Films of polypropylene, EVA, polyethylene, etc. are suitable, and a longitudinal uniaxially stretched film that is easy to tear in the longitudinal direction, that is, the direction of forming the seal portion is desirable. In addition, it goes without saying that the film may be formed by laminating a heat-sealable resin on a non-heat-welding film.

Also, it is desirable that the width of the elongated protruding piece is narrow, usually 1 mm.
The degree is suitable, but if the film used for the material is a pressure resistant film, it should be formed a little wider.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of an example of a container of the present invention filled with contents,
FIG. 2 is a sectional view taken along the line AA in FIG. 1, and FIG. 3 is the same as BB.
Line sectional enlarged views, FIGS. 4, 5, and 6 are front views of other examples, and FIG. 7 is a front view of an example in which the seal portion has a shape different from the above.

FIG. 1 shows a container 1 made of a film that is easily tearable in the longitudinal direction, provided with sealing portions 2 and 3 on both sides in the easy tearing direction. The sealing portion 3 is T-shaped and has an elongated protrusion 4 inward. The elongated protrusion 4 has a sharp tip portion a so that when the body portion of the container 1 is pressed, the container 1 bursts from the tip portion a.

Thus, the body portion has the sectional shape shown in FIG. 2, and the portion where the elongated protrusion 4 is provided has the sectional shape shown in FIG.

The one shown in FIGS. 4 and 5 is suitable for filling the seasoning of an instant food, and when the body of the container 1 is pressed, the stress concentrates on the elongated protrusions, and the tip thereof. The container 1 is torn from the part, and the contents are discharged without scattering from the torn part.

In addition, as shown in FIG. 6, the container 1 is divided into two parts 11 and 12 by providing a seal part 5 at the center thereof, and a seal part 3 having elongated protrusions 4 on both sides is provided, and a shampoo is provided on the container 11. If the container 12 contains a rinse, it becomes a shampoo set.When washing the hair, the container 11 is pressed and the shampoo is taken out and used.After that, the container 12 is pressed to take out the rinse and finish the rinse. It is something to do.

On the other hand, as shown in FIG. 7, the shape of the seal portion 3 is different from that described above, and an elongated protruding portion 41 is formed diagonally inside the seal end portion. It is torn only and the contents are taken out from the outside so that it does not easily remain inside.

The arcuate portions 31 are formed on both sides in the width direction of the seal portion 3 in FIGS. 1, 5, and 6 because the container 1 is broken at both ends of the seal portion 3 and This is to prevent the emission of

In addition, the disposable container of the present invention may be formed into a continuous package so as to continuously seal while containing the contents.

When the contents are taken out from the containers, they are made disposable as they are.

[Effect of device]

The present invention is as described above, and since the seal portion is provided in the easy tearing direction and the shape of the seal portion on the side where the content is to be discharged has a shape having an elongated protruding piece inside, a container filled with the content When the body part of is pressed, stress concentrates on the elongated protrusion, the container is torn from the tip of the elongated protrusion, the entire side of the elongated protrusion is torn, and the contents flow out, so the contents do not scatter. Therefore, there is no risk that clothes will be soiled due to scattering of contents, and the seal part is not separated from the container.
There is no danger that debris will get into food, etc.

Therefore, the disposable container of the present invention is suitable as a disposable container in which seasonings for instant food, shampoo for hair washing, rinse, etc. are enclosed.
