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. 6 filled with a rice cake 2 (hereinafter referred to as a package kagami-mochi) is widely used.

In this packaging kagami mochi, a plastic sheet is vacuum-formed to form a 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 formed. 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 that the traditional Kagami-mochi has is that the mold grows in a relatively short time, and that it cracks and hardens. This is because it can be successfully overcome and the mochi 2 inside can be kept in a soft and delicious state at the time of production for a considerably long period of 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 a mirror rice cake shape and to secure the required barrier property, 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. Further, for example, it is not easy to cut out a part of the container body portion 3a and peel off the container body portion 3a from the cutout portion. 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, in order to take out the rice cake 2 from the bottom side of the container body portion 3a, it is practically impossible to remove the vicinity of the constricted portion of the container body portion 3a.

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 cake has a problem that it is difficult to take out the rice cake 2 from the kagami rice cake container 1a, and there is a considerable risk in taking it 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 made of, and the container body is formed of a peelable multi-layer film, and the outer layer of the multi-layer film is provided with a notch for forming an opening knob.

[Action]

In the mirror cake container of this invention, the outer film layer can be peeled off.

〔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.

The bottom sheet 4 is also made of a plastic sheet, like the bottom sheet 4 of the ordinary kamochi container 1a, and is heat-sealed to the flange 5 to close the container body 3. As a material for the bottom sheet 4, a material having an easy peeling property with respect to the container body portion 3 is used, and the bottom sheet 4 can be easily peeled from the container body portion 3 when the rice cake 2 is taken out.

In the kagami mochi container 1 of the present invention, the sheet-like material 30 to be the container body 3 as described above is formed by a peelable multilayer film, and the notch 6 is provided in the outer film layer of the multilayer film. It is characterized by.

The notch 6 is for forming an opening knob, and is for hooking the tip of a nail or the like when opening to form the opening knob.

As shown in FIG. 3, the notch 6 is formed as a notch 60 in the sheet-like material 30 before vacuum forming into the container body portion 3, and the sheet-like material 30 is vacuum-formed into the container body portion 3. At the same time, the cut 6 is made.

As the sheet-like material 30, for example, polypropylene / release layer / polyethylene / release layer / polypropylene having a release layer interposed between plastic layers may be used, or polypropylene / polyethylene / polypropylene may be used. It is also possible to use a laminate of plastics without providing a release layer.

When the release layer is interposed, various plastics such as polyvinyl alcohol (EVOH), polycarbonate and nylon can be widely used in addition to the above.

The notch 6 is provided in each of the plastics layers constituting the sheet-shaped material 30 except the innermost plastics layer.

The notch 6 may have any shape such as a continuous line shape or a perforation line shape, and the cross-sectional shape thereof is as shown in FIG. 4 (a), (b),
Any other shape such as a V-shape, a rectangular shape, and a linear shape illustrated in (C) may be used.

When the sheet-like material 30 is composed of three or more layers, a cut 60 may be provided after stacking to form a cut 6 extending over a plurality of layers as shown in FIG. 4 (d). After providing the cut 60, the cut 6 of each layer may be displaced as shown in FIG. 4 (E) to improve the barrier property.

Further, the place where the notch 6 is provided, the overall shape of the notch 6 and the like may be arbitrary. In FIG. 1 and FIG. 2, a linear cut 6 is provided at a position slightly apart from the center of the container body 3 so that the cut 6 is on the rear side and a cut is made from the front side when decorating a rice cake. Although not visible, the notch 6 may be a straight line passing through the center of the container body 3 or may be a spiral shape as shown in FIG.

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 for the innermost layer of the multilayer sheet, the peelability between the innermost layer and the rice cake 2 is improved and the innermost layer is peeled from the rice cake 2. Can be made easier.

When used as a kagami mochi, the cut 6 is placed on three sides or the like so that the direction in which the cut 6 is not visible is facing the front side.

When eating the rice cake 2 inside, first, the bottom sheet 4 is peeled from the container body portion 3. Next, an opening knob is formed by hooking the tip of a nail or the like on the notch 6, and the opening knob is held and pulled outward to peel off the outermost layer. Similarly, the second layer from the outer side and the third layer are peeled off from the outer layer in sequence, and finally only the innermost layer 1 is formed. Since the innermost layer is thin, even if there is no notch 6, it can be easily torn and peeled from the end of the flange 5 or the like. Of course, the innermost layer is peeled off from the innermost layer by cutting the innermost layer with a kitchen knife or the like, or the innermost layer is peeled off with the same volume as when the outermost layer is peeled off by forming a cut in the innermost layer with a kitchen knife or the like. It doesn't matter.

[Effect of device]

The present invention is configured as described above, and by forming the container body with a peelable multi-layer film and providing the outer layer of the multi-layer film with a notch for forming the opening knob, the notch of the nail is formed. The tip of the opening is hooked to form an opening knob, and the opening knob is held and pulled outward to sequentially peel the outer plastic layer, leaving only one thin innermost layer at the end. The inner layer can be easily torn and peeled by hand.

Further, by providing one innermost layer having no cuts at all, the barrier property is sufficiently ensured and deterioration of the filled rice cake can be prevented.
