Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a kagamimochi container, and relates to a kagamimochi container that is easy to open and take out the rice cake.

[Conventional technology]

Recently, as a kagami-mochi, a plastic kagami-mochi container 1a as shown in FIG. 8 filled with a rice cake 2 (hereinafter referred to as a packaged kagami-mochi) is widely used.

In this packaging kagami mochi, a plastic sheet-like material is vacuum-formed to form a kagamimochi-shaped container body portion 3a having an open bottom, and the container body portion 3a is inverted to fill the rice cake 2 and then the bottom portion is opened. It is sealed with a bottom sheet 4 made of plastics, then heat-treated and put into a distribution process.

Such packaged kagami mochi has been widely accepted by the public and has spread rapidly, and nowadays it has a momentum that surpasses traditional kagamimochi, which is a double layer of flat, round rice cakes.

This is because the packaged Kagami-mochi has a much longer shelf life than the traditional Kagami-mochi, and the disadvantage of the traditional Kagami-mochi is that the mold grows in a relatively short time and it hardens because it does not crack. This is because the rice cake 2 inside can be maintained in a soft and delicious state at the time of production for a considerably long time.

[Problems to be solved by the device]

However, the conventional packaged rice cake cake has a problem that it is difficult to take out the rice cake 2 from the rice cake cake container 1a, and there is a considerable risk in taking it out.

That is, the container body portion 3a is closed at the center and near the lower end. On the other hand, the rice cake 2 is connected from the top to the bottom.
In this way, since the container body portion 3a is constricted and the rice cake 2 is integrated, it is not possible to take out the rice cake 2 from the bottom side of the container body portion 3a simply by peeling the bottom sheet 4 from the container body portion 3a. Can not. This is because the rice cake 2 above the narrowed portion of the container body portion 3a is caught in the narrowed portion. In order to take out the rice cake 2 from the bottom side of the container body 3a, it is necessary to remove the bottom sheet 4 and remove the vicinity of the constricted part of the container body 3a with a considerable vertical width.

On the other hand, polypropylene or the like is used as the material of the container body portion 3a, but these have high adhesion to the rice cake 2. Further, in order to keep the rice cake 2 in the shape of a mirror rice cake and to secure the required barrier property, in particular, moisture resistance, the container body portion 3a is required to have a considerable thickness and hardness. Therefore, it is not easy to take out the rice cake 2 from the bottom side of the container body portion 3a even if the temporary container body portion 3a is not constricted. This is because the container body portion 3a is firmly held in a constant shape, and the rice cake 2 is tightly attached to the inner surface of the container body portion 3a held in the fixed shape. Also, for example, the container body portion 3a
It is not easy to cut out a part of the container and remove the container body 3a from the cut out part. This is because the part to be peeled off sticks to the rice cake 2, and the rice cake 2 is strongly curved in the shape of the rice cake 2 and resists the force of separating from the surface of the rice cake 2. In particular, the vicinity of the constricted portion of the container body portion 3a is firmly constricted in a constricted shape and is difficult to peel off. Therefore, from the bottom side of the container body 3a, the rice cake 2
It is practically impossible to remove the vicinity of the constricted part of the container body portion 3a in order to take out.

After all, in order to take out the rice cake 2 from the container body 3a, the rice cake 2 is cut together with the container body 3a using a kitchen knife or the like, and the container body 3a and the rice cake 2 are separated after cutting, as is generally done at present. There is no other way.

However, as described above, the thickness and hardness of the container body portion 3a are considerably large. Therefore, the rice cake 2 with the container body 3a with a knife etc.
In order to cut, the container body portion 3a must first be cut by applying a considerable pressing force to a kitchen knife or the like.

The container body 3a is formed by vacuum-molding plastic, and its outer surface is smooth. Therefore, the blade of the kitchen knife is likely to slip on the surface of the container body 3a.

In this way, it is necessary to apply a considerable pressing force to the knife, etc., and moreover, since the blade of the knife easily slips on the outer surface of the container body 3a, for example, apply the knife blade to the vacuum at the top of the container body 3a. Immediately after being pressed with a strong force from above, the blade of the kitchen knife slides on the top of the container body 3a, and the blade often repeats upwards and injures fingers.

As described above, the conventional packaged rice cakes have a problem that it is difficult to take out the rice cakes 2 from the kagami rice cake container 1a, and there is a considerable risk in taking them out.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention provides a container for filling rice cake, which is formed by vacuum forming a sheet-like material of plastics into a mirror rice cake shape, and a plastic container for closing the container body. And a bottom sheet, and an adhesive layer having an easy peeling property is provided on the container body, and a zipper is defined by a pair of half-cut lines punched from both front and back surfaces.

[Action]

In the kagamimochi container of this invention, a part of the container body is broken by the zipper.

〔Example〕

Referring to the drawings, one embodiment of the present invention will be described. FIG. 1 and FIG. 2 are a side view and a plan view, respectively, of a rice cake cake container 1 of the present invention.

The kagamimochi container 1 is composed of a container body 3 and a bottom sheet 4, like the ordinary kagamimochi container 1a.

The container body 3 is, like the container body 3a of the ordinary kagamimochi container 1a, formed by vacuum-molding a sheet-like material 30 of plastics into a two-tiered kagamimochi shape, and a flange-shaped flange 5 at the lower end. Are formed.

Further, the bottom sheet 4 is also made of a plastic sheet-like material like the bottom sheet 4 of the ordinary kamochi container 1a, and the flange 5 is heat-sealed to close the container body 3.

The kagamimochi container 1 of the present invention is provided with an adhesive layer 9 having an easy peeling property on the container body 3 as described above, and a pair of half-cut lines a, a'and b, b'perforated from both front and back surfaces. It is characterized in that the zipper 8 is sectioned and formed.

The container body 3 is formed from a multilayer sheet 30 as shown in FIGS. 3 and 4.

The multi-layered sheet 30 is composed of three or more multi-layered sheets including front and back of a polyolefin resin sheet such as polypropylene and an adhesive layer, and the adhesive strength between the adhering surfaces 6, 9 and 7, 9 of the multi-layered sheet is easy. Peeling range (200g / 15m
m width ~ 1300g / 15mm width).

Examples of the configuration of the multilayer sheet 30 are as follows.

1) Polypropylene / easy peeling resin / polypropylene (manufactured by multi-layer coextrusion method or sandwich laminating method by extrusion coating of easy peeling resin) 2) Polypropylene / adhesive (adhesive strength adjustment) / polypropylene (manufactured by dry laminating method) Polyolefin resin can be used as the easy peeling resin, and specifically, the following ones are listed.

CMPS V series V-70 (trade name, manufactured by Mitsui Polychemicals Co., Ltd.) Dicktherm EL series EL-330 EL-701 (trade name, manufactured by Dainippon Ink and Chemicals Co., Ltd.) Other than polypropylene and polyethylene-based blend resins An extruded grade polyethylene simple substance resin can also be used.

3) Polyester / Adhesive / Polypropylene However, polyester is on the outside. (Manufacturing by Dry Lamination Method) In this embodiment, as the multilayer sheet 30, a coextrusion sheet having a structure of polypropylene 255 μ / polyethylene 40 μ / polypropylene 225 μ and a total thickness of 500 μ is used.

In this multi-layered sheet 30, the adhesive strength between the two 255 μ-thick polypropylene layers 6 and 7 and the polyethylene layer 40 μ-thickness 9 used as the adhesive layer is adjusted to a range having an easy peeling property.

A zipper 8 as shown in FIGS. 3 and 4 is formed on the multilayer sheet 30.

The zipper 8 has two parallel half-cut lines a and a'drilled from the back side in the center of the multilayer sheet 30 and half-cuts from the front side close to the outside of each half-cut line a and a '. It consists of lines b and b '.

In this embodiment, each half-cut line a, a ', b, b'is stopped to the depth of contact with the adhesive layer 9 as shown in FIG.
As shown in FIG. 5, it is preferable to form a hole to a depth slightly exceeding the adhesive layer 9 because good delamination can be easily obtained.

In the present embodiment, the half-cut line a, a'is a gripping piece 10 with a portion sandwiched by the full cut line c, c'as one full-cut line c, c ', and the full cut line. Half-cut lines d and d'which reach half-cut lines b and b'obliquely from the ends of c and c'are drilled from the surface side, but these full-cut lines c and c'and half-cut lines d and d ′ May not be provided.

In the kagami mochi container of the present invention, the multilayer sheet as described above
30 is vacuum-formed to form the container body portion 3 as shown in FIGS.

When used as a kagami mochi, the zipper 8 is placed on three sides or the like so that the direction in which the zipper 8 cannot be seen is directed toward the front side.

When eating the rice cake 2, the gripping piece 10 is gripped and pulled upward to tear the container body portion 8 along the zipper 8. As a result, the container body portion 3 is divided into vertical halves, and by removing each of the divided vertical halves from the rice cake 2, the removal of the rice cake 2 is completed.

FIG. 6 shows a multi-layer sheet of another embodiment of the present invention, in which the half cut lines a, a'and b, b'are not provided up to the end side of the flange 5 and the tip ends of the full cut lines c, c '. Is connected by a full cutting line e, and a portion surrounded by the full cutting line e and the full cutting lines c and c'is a gripping piece 10.

FIG. 7 shows still another embodiment of the present invention, which is a half-cut line a, a '.
And b, b ′ It is a shape.

The present invention is not limited to the above-described embodiment, and the structure, position, etc. of the zipper are not limited to those shown in the drawings. For example, the half cut lines a, a ′, b, b ′ may be perforated half cut lines.

If a sheet in which higher fatty acid such as stearic acid is added in the range of 0.1 to 5% by weight is used as the innermost layer of the multilayer sheet 30, the peelability between the container body portion 3 and the rice cake 2 can be improved. Thereby, the zipper 8 can be easily torn, and the rice cake 2 can be easily taken out from the container body portion 3 after the zipper 8 is torn.

[Effect of device]

The present invention is constructed as described above, and the zipper is pulled outward by providing the adhesive layer having easy peeling property on the container body and partitioning the zipper with the pair of half cut lines punched from both front and back surfaces. For example, the part sandwiched by a pair of half-cut lines drilled from the front and back sides can be peeled off between the adhesive layers having an easy peeling property to tear and open the container body, and each portion of the teared and opened container body You can take the rice cake out of it. This makes it possible to take out the rice cake from the kagami-mochi container much more easily and safely than in the case of cutting the rice cake together with the kagami-mochi container with a conventional knife.

If a sheet containing a higher resin acid such as stearic acid added in the range of 0.1 to 5% by weight is used as the innermost layer of the container body, the zipper can be easily torn, and after the zipper is torn from the container body part. You can take out the rice cake easily.
