Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kagami-mochi container, and more particularly to a kagami-mochi container which is easy to take out and has a good appearance.

[0002]

2. Description of the Related Art Kagami-mochi containers for filling and packaging Kagami-mochi are used in order to prevent the mold and cracking of Kagami-mochi and preserve them for a long time. A conventional kagami-mochi container is composed of a container body formed by molding a resin sheet into a kagami-mochi shape, and a bottom sheet that seals the container body after filling the container body with rice cake.

In order to remove the rice cake from the kagami mochi container as described above, the rice cake has been cut with a knife or the like, but the container body has a certain thickness and hardness. In addition, since the outer surface of the container body is smooth, it is not easy to cut the container body with a knife or the like.

In order to solve such a problem at the time of opening such a rice cake cake container, there has been proposed a rice cake container which is provided with a thin portion or a notch in the container body so that it can be easily torn by hand (Japanese Patent Laid-Open No. Hei 10-1999). 4-308722, JP-A-4-308725
issue). However, there is a problem that even if the rice cake can be taken out by easily tearing the container body part by hand, the rice cake cannot be separated because the rice cake is solidified.

For this reason, when a middle partition plate is fitted in the container body to divide the freshly-brewed rice cake filled in the container body into an arbitrary number of partitions, the solidified rice cake is taken out from the kagami-mochi container. There has been proposed a mirror rice cake container that can easily separate rice cakes (JP-A-2-127259, etc.).

[0006]

However, in the above-mentioned rice cake cake container in which the inner partition plate is fitted in the container body, when the inner partition plate is in contact with the inner surface of the container body, There was a problem that the market value of Kagami-mochi was significantly reduced due to the recognition of the presence of a partition board.

On the other hand, if the inner partition plate is included in the filled rice cake, contact between the inner partition plate and the inner surface of the container body is prevented, but the inner partition plate is manually mounted. Or, there is a problem that the control of the automatic mounting becomes complicated and the workability is deteriorated and the speed of automatic packaging is hindered.

Further, in a mirror rice cake container using a container body part in which an inorganic filler is contained in a resin sheet for molding the container body part and simply whitened, between the container body part and the rice cake filled therein. When air bubbles are generated in the rice cake, there is a problem that the appearance of the kagami-mochi container looks like moldy on the rice cake.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a mirror rice cake container which has an extremely good appearance and has a high work efficiency and which can be automatically packaged.

[0010]

In order to achieve such an object, the container for rice cake of the present invention is made of polypropylene 100.
A container body formed by shaping a polypropylene sheet made of a composition containing 40 to 150 parts by weight of an inorganic filler and 1 to 50 parts by weight of a hiding property-imparting agent in a mirror-like shape with respect to parts by weight, and the container body part. A bottom sheet for sealing the
The rice cake filled in the container body is divided into two or more partitions for partitioning.

[0011]

The container body constituting the kagamimochi container is a polypropylene sheet molded into a kagamimochi shape. The polypropylene sheet contains 40 to 150 parts by weight of an inorganic filler and 100% by weight of polypropylene and a concealing agent. Since the composition is contained in a proportion of 1 to 50 parts by weight, even if the partition plate provided in the container body is in contact with the inner surface of the container body, Due to the action, the presence of the partition plate is completely hidden from the outside, and even if air bubbles occur between the container body and the rice cake filled in the container body, the rice cake should have the appearance of mold. Further, the container body can be easily torn by hand due to the action of the inorganic filler contained in the container body, which facilitates the unsealing.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are a side view and a perspective view, respectively, showing an example of a rice cake cake container of the present invention. 1 and 2, a mirror rice cake container 1 of the present invention has a container body portion 3 in which a rice cake 2 is filled, and a flange portion 3b of the container body portion 3 which is fixed to the container body portion 3 to seal the container body portion 3. It is provided with a bottom sheet 4 and a partition plate 5 that divides the filled rice cake 2 into two or more (four divisions in the illustrated example).

A container body portion 3 which constitutes the kagamimochi container 1 of the present invention.
Is a polypropylene sheet formed into a mirror cake shape by vacuum forming and / or pressure forming, and has an opening 3a and a flange 3b in the lower portion.

The polypropylene sheet used for molding the container body 3 is a polypropylene sheet made of a composition in which polypropylene is mixed with an inorganic filler and a concealing agent.

The inorganic filler to be blended with the polypropylene sheet is not particularly limited as long as it can be used for packaging foods, but magnesium silicate (MgSiO ₄ ) is particularly preferable. Here, magnesium silicate is a general term for substances having a composition in which magnesium oxide, silicon dioxide, and water are bonded in various proportions (Kyoritsu Shuppan, "Kagaku Encyclopedia", Vol. 3, p. 310), and is used practically. It is preferable to use talc.

The mixing ratio of this inorganic filler is 40 to 150 parts by weight, preferably 60 to 145 parts by weight, based on 100 parts by weight of polypropylene. If the compounding ratio of the inorganic filler is less than 40 parts by weight, it may not be easy to tear the container body portion 3 by hand. Also, 150
If it exceeds the weight part, it becomes difficult to form the composition into a sheet, which is not preferable.

Inorganic pigments are particularly preferably used as the hiding property-imparting agent to be incorporated into the polypropylene sheet together with the above-mentioned inorganic filler. Specifically, for example,
Examples thereof include titanium dioxide, titanium yellow, red iron oxide, carbon black, cobalt oxide, and mixtures thereof.

The blending ratio of the hiding property-imparting agent is 1 to 50 parts by weight, preferably 20 to 45 parts by weight, based on 100 parts by weight of polypropylene. If the blending ratio of the hiding property-imparting agent is less than 1 part by weight, the effect of preventing the deterioration of the appearance of the rice cake cake as described below cannot be sufficiently obtained. Undesirably deteriorates the food-likeness and lowers the gas barrier property of the container body 3.

The polypropylene sheet forming the container body 3 may have either a single layer structure or a laminated structure. In the case of a laminated structure, for example, a three-layer structure of polypropylene / polyvinyl alcohol / polypropylene is preferable, but when a polypropylene sheet having such a laminated structure is used, good easy-opening property is imparted to the container body portion 3. Thus, it is preferable to mix an inorganic filler in each layer constituting the polypropylene sheet.

Further, for the purpose of improving the peeling property between the container body portion 3 and the rice cake 2 at the time of opening, a higher fatty acid such as stearic acid may be added to the polypropylene sheet. However, when the polypropylene sheet having the above-mentioned laminated structure is used, the higher fatty acid may be added to the layer formed in the container body 3 and in contact with the rice cake 2. The blending ratio of the higher fatty acid is preferably about 0.1 to 5% by weight based on the polypropylene sheet.

The thickness of such a polypropylene sheet can be appropriately set according to the weight of the rice cake 2 filled in the container body portion 3. Specifically, since the weight of the rice cake 2 filled in the container body portion 3 is usually about 160 g to 8 kg, the thickness of the polypropylene sheet is 0.2 to 1.
It can be about 5 mm. This thickness is 0.2mm
If it is less than the range, it may be difficult to maintain the shape of the container body portion 3 in a mirror-like shape when filling the rice cake 2, and the strength may be reduced. On the other hand, if the thickness exceeds 1.5 mm, softening of the polypropylene sheet by a heater becomes difficult when vacuum forming the polypropylene sheet, which is not preferable.

By forming the container body 3 using the polypropylene sheet as described above, even if the partition plate 5 provided in the container body 3 is in contact with the inner surface of the container body 3, The presence of the partitioning plate 5 is completely hidden from the outside by the action of the hiding property-imparting agent contained in the part 3. Further, even if air bubbles are generated between the container body portion 3 and the rice cake 2 filled in the container body portion 3, it is possible to prevent the rice cake 2 from having an appearance such as a mold due to the action of the concealing agent. Further, the action of the inorganic filler contained in the container body portion 3 allows the container body portion 3 to be easily torn by hand, which facilitates the unsealing.

The bottom sheet 4 for sealing the opening 3a of the container body 3 may be any one having an easy peeling property with respect to the container body 3, and various plastics can be used. In particular, single-layer sheets of polypropylene, polyethylene, etc., or those and polyester,
A laminated sheet in which polyamide, polystyrene, aluminum foil or the like is laminated can be used. This bottom sheet 4
Usually has a thickness of about 50 to 300 μm. Also,
The size and shape of the bottom sheet 4 is at least the container body portion 3.
Any shape may be used as long as it can completely cover the opening portion 3a of the container body portion 3, but the periphery of the flange portion 3b of the container body portion 3 and the bottom sheet 4
It is preferable that the shape is such that the peripheral edge of the is substantially the same.

The kagamimochi container of the present invention can be manufactured, for example, as follows.

First, the above-mentioned polypropylene sheet is manufactured, and then this polypropylene sheet is subjected to vacuum forming and / or pressure forming. This vacuum forming and pressure forming can be performed according to a conventional method. For example, in the case of vacuum forming, if a polypropylene sheet is heated and softened by a heater or the like, and pressed from a female mold side to obtain a desired shape while pressurizing as needed, the polypropylene sheet may be pressed against a male mold for molding. Good. Further, in the case of pressure molding, the polypropylene sheet may be heated and softened by a heater or the like, pressured by air or the like from the male mold side, and pressed into a female mold so as to obtain a desired shape.

As for the molding conditions, in the case of vacuum molding, the heating temperature of the polypropylene sheet is preferably 150 to 180 ° C., and the degree of vacuum is preferably 600 to 650 mmHg. In the case of pressure molding, the heating temperature of the polypropylene sheet may be set to 150 to 180 ° C. and sufficient pressure may be applied to deform the sheet.

After forming the mirror cake-shaped container body portion 3 in this manner, the freshly-brewed rice cake 2 is first filled into the container body portion 3 through the opening 3a, and then the partition plate 5 is placed. It is supplied from a hopper or the like, and is fitted into the container body 3 while penetrating the rice cake 2 in a soft state from the opening 3a of the container body 3. Alternatively, the partition plate 5 may be placed in the container body portion 3 in advance, and then the container body portion 3 may be filled with freshly moistened rice cake.

Next, the container body 3 is sealed with the bottom sheet 4 so as to cover the opening 3a of the container body 3, and the kagamimochi container 1
Get.

After the mirror rice cake container 1 thus molded and packaged is served, when the rice cake 2 is taken out for edible use, first, the bottom sheet 4 is peeled from the container body 3.
Next, by holding both sides of the flange 3b of the container body 3 by hand and pulling both sides outward, the container body 3 can be easily torn. Thereby, the rice cake 2 can be taken out from the container body 3. Then, the solidified taken-out rice cake 2 is separated into each rice cake piece by lightly pressing the part of the intermediate partition plate 5 which is divided by the partition plate outwardly with fingers or the like. It's extremely easy and reliable. If you want to divide each mochi piece divided in this way into smaller pieces,
Since the shape itself is thin, it can be divided very easily even when the kitchen knife is set up.

Next, the intermediate partition plate that can be used in the kagamimochi container of the present invention will be described. 3 and 4 show
It is a perspective view and a top view which each show an example of the partition plate which can be used for the kagamimochi container of this invention, respectively. In FIGS. 3 and 4, the middle partition plate 5a is formed integrally so that partition plates 12 and 12 'having a predetermined shape having a stepped portion are extended around a fulcrum 11a. . And, in the vicinity of the fulcrum 11a of the partition plate 12,
Thin portions 12a and 12b are formed along the entire length in the height direction of the partition plate along the fulcrum 11a, and the partition plate 12 can be bent at the thin portions 12a and 12b.

The partition plate 5a is integrally molded by injection molding or the like and can be formed by using all moldable synthetic resin members. Among them, polypropylene containing an inorganic filler is environmentally friendly. It is most preferably used from the point of. By being integrally molded in this way, it can be used as it is without any extra manual work such as assembling at the time of use, so that it can be efficiently and hygienically fitted onto the container body 3. You can

Partition plate 12 constituting the intermediate partition plate 5a
Since it can be bent at the thin portions 12a and 12b, as shown in FIG.
Can be folded substantially parallel to each other along the other partition plate 12 '. Thus, per one in the partition plate 5a, accommodating as thick two sheets and the partition plate 12 thickness of 1 sheet of a slightly thicker L ₁ than the total the thickness of the storage width of 'the partition plate 12 Is possible. Therefore, a plurality of partition plates can be neatly stacked in parallel with each other in a compact state in which the partition plate 12 is bent, and storage can be performed much more efficiently than before when stored. Particularly in an automatic packaging line, since a large amount of partition plates can be stored in the hopper at one time, it is possible to significantly reduce the number of times the partition plates are replenished during the operation. Moreover, since they can be piled up in the above manner, they can be arranged and stored, and can be smoothly supplied from the hopper, and the effect on work efficiency is extremely large.

The method of forming the thin portions 12a and 12b is not particularly limited as long as the partition plate 12 is formed so thin that it can be bent at the above-mentioned portions. In FIGS. 3 to 5, notches having a bowl-shaped cross section are provided on the same side surface of the partition plate 12, but the invention is not limited to this, and one thin portion is provided on one side surface of the partition plate 12 and the other thin portion is provided on the partition plate 12. It may be provided on the other side surface of 12. Further, if the thin-walled portion has a cross-sectional shape having a bending function, for example, as shown in FIG. 6, the cross-sectional shape is a substantially trapezoidal shape (see FIG. 6).
It goes without saying that (b), (c)) and any other cross-sectional shape may be used. Further, the thin portion (for example, with respect to the thin portion 12a) is not limited to one side surface of the partition plate 12, but may be provided as thin portions 12a ₁ and 12a ₂ on both side surfaces as shown in FIGS. 6 (a) and 6 (b). Good.

Further, not only the partition plate 12 but also the partition plate 12 'may be provided at the same time. By also providing the partition plate 12 ', either the partition plate 12 or 12' can be arbitrarily selected and bent. Therefore, especially in an automatic packaging line, the direction of the middle partition plate is not taken into consideration, and the partition plate 12 'or 12' is put into the hopper. It becomes possible to store them in line.

In the above embodiment, the case where the intermediate partition plate 5 is divided into four has been described, but the intermediate partition plate 5 is not limited to this, and includes a single plate-shaped body for dividing into two. Any number of divided pieces can be used in the present invention.

FIG. 7 shows an example of a middle partition plate in the case of being divided into eight parts, and the middle partition plate 5b is composed of partition plates 22, 22 ', 22 ", 22"' of a predetermined shape having a stepped portion. Fulcrum 21
It is formed so as to extend around a, 21a ', and 21a'', and is integrally molded.

In the vicinity of the fulcrums 21a, 21a ', and 21a''of2''', the thin portions 22'a, 22'b (positions near the fulcrum 21a are provided along the respective fulcrums over the entire length in the height direction of the partition plate. ), Thin portions 22 ″ a and 22 ″ b (positions near the fulcrum 21a ′), and thin portions 22 ′ ″ a and 22 ″ ′ b (positions near the fulcrum 21a ″), respectively. Thin part 2
2'a, 22 'b, 22 "a, 22" b, 22'"a,
22 '''b partition plates 22', 22 '', 22 '''
Each can be bent. Then, as shown in FIG. 8, the partition plates 22 ′, 22 ″, 22 ′ ″ can be folded substantially parallel to each other along the partition plate 22. As a result, as in the case of the above-mentioned four divisions, a plurality of partition plates 22 ′, 22 ″, 22 ′ ″ can be folded and placed in parallel in a compact state in an orderly manner. It enables much more efficient storage than before, and the work efficiency in the automatic packaging line is greatly improved.

Also in this case, the method of forming the thin portion is
As described above, the forming method is not particularly limited as long as the partition plates 22 ′, 22 ″, and 22 ′ ″ are formed in such a thickness that they can be bent.

FIG. 9 shows an example of a three-divided partition plate, and the partition plate 5c is composed of three partition plates 32, 32 ', 32 "' having a predetermined shape having a stepped portion with the fulcrum 31a as the center. Is integrally formed.

Of these partition plates, for example, 2
In the vicinity of the fulcrum 31a of the partition plates 32, 32 ',
Thin portions 32a and 32'a are formed along the entire length in the height direction of the partition plate along the fulcrum 31a, and the partition plate 3 is formed at these thin portions 32a and 32'a.
2, 32 'can be bent. Then, the partition plates 32, 32 'are bent at a predetermined angle in the thin portions 32a, 32'a so as to be overlapped with each other, and the surface formed by the overlapped partition plates 32, 32' is the remaining partition plate 32 ''. The surface can be made substantially flush with the surface formed by. Thereby, as in the case of the above-mentioned four divisions, the middle partition plate 5 having a plurality of (3) partition plates is provided.
Can be stored compactly.

Also in this case, the thin portion may be formed for all three partition plates, or the partition plate 1
It may be formed only on one sheet. When three partition plates are formed, they can be housed in this state by bending the thin plates at appropriate angles and stacking the three together. When formed only on one partition plate, the middle partition plate 5c is housed in a gentle inverted V shape by bending it substantially parallel to one of the other adjacent partition plates. be able to.

Also in this case, the method of forming the thin portion is
As described above, the forming method is not particularly limited as long as the partition plate is formed so thin as to be bendable.

In the above example of the partition plate,
As shown in the figure, regarding the shape of each partition plate forming the middle partition plate, the case where the shape formed by the outer edge thereof is substantially the same as the shape formed by the inner side surface of the container body portion 3 has been described, but the shape is not limited to this. Not something.

Further, in the present invention, the intermediate partition plate may have a structure in which a plate-shaped body is integrally formed on the bottom of at least one of the above-mentioned fulcrums.

For example, as shown in FIGS. 10 and 11, in the intermediate partition plate 5d, partition plates 42 and 42 'having a predetermined shape are fulcrum 4
It is formed so as to extend around 1a, and a plate-like body 43 is integrally formed at the bottom of the fulcrum 41a. This plate-like body 43 serves as a stopper, and when the inner partition plate 41 is fitted in the container body portion 3, the bottom surface of the plate-like body 43 is substantially the same as the surface of the rice cake 2. It is intended to prevent the intermediate partition plate 41 from entering too deeply into the packaging container by fitting the intermediate partition plate 41 into the packaging container so as to allow it to penetrate to such a depth. Therefore, the plate-like body 43 is not particularly limited in shape, size and the like as long as the above-mentioned effects can be obtained, and any plate-like body can be used.

As shown in FIG. 12, for example, the partition plate 5d is filled in the container body portion 3 from the opening 3a with freshly-brewed rice cake 2 through a nozzle or the like, and then supplied from a hopper. The inner partition plate 5d to the opening 3 of the container body 3
The soft rice cake 2 is inserted from a and is fitted into the container body 3. At this time, by fitting the plate-like body 43 integrally formed on the bottom of the middle partition plate 5d to a depth such that the bottom surface of the plate-like body 43 is substantially the same as the surface of the rice cake, the middle partition plate is fitted. It is possible to prevent the 5d from penetrating too deeply into the rice cake, and to easily position the rice cake. Then, after this, the container body portion 3 is sealed with a bottom sheet (not shown) so as to cover the opening 3a of the container body portion 3, and a kagami mochi container can be obtained.

A cutout may be provided at a predetermined position of the plate-like body. That is, for example, as shown in FIG.
The middle partition plate 5e is formed such that partition plates 52, 52 'having a predetermined shape extend around a fulcrum 51a, and cutouts 59, 5
9'is formed. Further, a plate-like body 53 is further integrally formed on the bottom of the fulcrum 51a, and the notch 59,
It is provided to fit inside 59 '.

The plate-like body 53 is provided with a cutout portion 53 '. Both side portions 53 ₁ and 53 _{2 of} this cutout portion 53 ′
Has ribs that are slightly raised in a mountain shape as shown in FIG. When the middle partition plate 5e is used, when the partition plate 52 is folded over at the thin portions 52a and 52b and opened so as to ride over the ribs 53 ₁ and 53 ₂ , the bottom of the partition plate 52 is a plate-shaped member. 53
The ribs 53 ₁ and 53 ₂ within the notch 53 ′
Locked by. Therefore, the position of the partition plate 52 can be easily determined at a predetermined angle, and the workability is improved.

The cutout portion 53 'of the plate member 53 is
As shown in FIG. 14 (b), both side portions 53 ₁ and 53 ₂ may be inclined in opposite directions in the vertical direction. By doing so, similarly to the above, when the middle partition plate 51 is used, when the partition plate 52 is opened from the folded state, the partition plate 52 is housed in the notch portion 53 ′ of the plate-like body 53, Moreover, it is locked by both side portions 53 ₁ and 53 ₂ , so that the position of the partition plate can be easily determined at a predetermined angle.

In the above example, the notch 53 'penetrates the plate-like body 53, but the shape or the like is not particularly limited as long as it has the above-described operational effects. .

The kagamimochi container of the present invention is not limited to the above-described embodiment, and, for example, a container body 3 having a linear thin portion or a flange 3b of the container body 3 may be used. A notch may be provided.

Next, the present invention will be described in more detail with reference to experimental examples. (Experimental Example) 100 parts by weight of a polypropylene composition containing 40% by weight of talc (magnesium silicate) as an inorganic filler, and a masterbatch having the following composition as a hiding property-imparting agent (manufactured by Pigment Co., PPF-). C-01852
) Was blended in a proportion of 3 parts by weight to prepare a composition for polypropylene sheet.

Masterbatch composition Base resin (polypropylene): 75 parts by weight Titanium oxide: 20 parts by weight Titanium yellow: 4 parts by weight Red iron oxide: 0.03 parts by weight Carbon black: 0.02 parts by weight Polyethylene wax, etc. Next, a polypropylene sheet having a thickness of 0.55 mm was produced using the above composition for polypropylene sheet.

The above polypropylene sheet was placed on a frame having a female mold in the shape of a rice cake, and the heater temperature was 180 ° C.
A vacuum-molded container body was formed by vacuum forming under a reduced pressure of 600 mmHg.

On the other hand, a four-division partition plate as shown in FIG. 3 was prepared using the above polypropylene composition. The shape of the outer edge of the partition plate is the same as the shape of the inner surface of the container body.

Next, the rice cake 55 freshly sprinkled in the container body described above.
After filling with 0 g, the partition plate was fitted into the container body while penetrating the rice cake. After cooling, the bottom sheet (PET12 / LMD / NY) is placed on the flange of the container to cover the opening.
15 / LMD / CMPS, Tohcello Chemical Co., Ltd. 013C80, thickness 1
07 μm) was heat-sealed to produce a square kagami-mochi container with a flange having a side length of 150 mm.

It was confirmed after opening that this kagamimochi container was in a state in which the inner partition plate was in contact with the inner surface of the container body, but before the opening, the presence of the inner partition plate was completely hidden from the outside and the appearance Was good. In addition, the bubble portion generated between the container body and the rice cake was not white, so that the rice cake did not appear to have mold and the appearance was good. Further, the container body portion could be easily torn by hand and opened easily, and after opening, the rice cake could be easily divided into each rice cake piece partitioned by the partition plate.

[0059]

As described above in detail, according to the present invention, the presence of the partition plate is completely prevented from the outside even if the partition plate fitted in the container body portion is in contact with the inner surface of the container body portion. Also, even if bubbles are generated between the container body and the rice cake filled in the container body, it is possible to prevent the rice cake from having an appearance like that of mold, and the appearance becomes extremely good. Since the body part can be easily torn by hand, it is easy to open and to separate the solidified rice cakes easily.

Further, by providing a thin portion in the height direction of the partition plate in the vicinity of the fulcrum of the middle partition plate, the partition plate can be bent at this thin part, and in such a bent state. By stacking them on top of each other, they can be compactly stored during storage, and especially in an automatic packaging line, they can be compactly arranged and stored in the hopper, and the intermediate partition plate can be smoothly fed from the hopper. The effect is that work efficiency is improved. Further, by being integrally molded, it is possible to efficiently and hygienically mount the container on the container without using extra manual work such as assembling at the time of use, and it is possible to cope with automatic packaging.

Further, in the above-mentioned structure, a plate-shaped body is integrally formed on the bottom of at least one of the fulcrums so as to fill the container body with freshly-brewed rice cake, and When the inner partition plate is penetrated into the filled rice cake for partitioning, the plate-like body functions as a stopper, and the inner partition plate for packaging is positioned so as not to go too deep into the rice cake.

Further, by forming a notch at a predetermined position of the plate-like body, when the middle partition plate stored in a bent state is opened and used, the opened partition plate is locked at this notch. Therefore, the partition plate can be easily set at a predetermined position, and the workability is improved.
