Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice cream container, and more particularly to a cup-shaped ice cream container containing sugar and a method for producing the same.

[0002]

2. Description of the Related Art By putting a sugar in a constituent material of an ice cream container, it is possible to obtain a variety of changes such as flavor and mouthfeel in the edible container itself by changing the kind of the sugar and the sugar content.

However, ice cream containers containing sugar are
Due to its high hygroscopicity, it is difficult to maintain the original shape of the container for a long time after sintering and molding. In particular, as the content of sugar increases, the hygroscopicity also increases, and one neck in terms of shape retention Another problem is that long-term storage of the container, which maintains the original shape at the time of molding, is another difficulty.

[0004] In addition to the difficulties in shape retention, the sugar-containing container has a problem that the flexibility remaining in the sheet material during firing makes a series of operations for firing and molding difficult, and the shape of the container is also difficult. The mainstream is a cone style that employs a winding means in which a sugar-containing material fired exclusively in a sheet shape is wound in a trumpet shape, and a large-diameter opening is formed upward and a tapered closing portion is formed below.

[0005] Further, a cup-shaped ice cream container obtained by press-forming a calcined sugar-containing sheet material in a concave-convex mold is subjected to local press distortion in the sheet material at the time of press molding, which varies locally. The container after molding tends to spread to a sheet-like state before molding around its bent portion (corner portion) such as a corner portion where deformation load is large, and can maintain the original container shape at the time of molding. The period lasted about 10 days.

[0006] With the passage of time, as the amount of moisture absorbed by the container itself increases, the container is greatly deformed from the vicinity of the opening thereof, and tends to be deformed to approach a sheet state before molding. In addition, when this cup-shaped container is used as a Monaka-type container, the irregularity due to the deformation of each of the pair of upper and lower containers results in impaired commercial value.

[0007] Even in a cone in which the above-mentioned sugar-containing fired sheet material is wound in a trumpet shape, the cone is deformed due to the moisture absorption of the cone itself with time, and furthermore, the peeling phenomenon from the overlapped portion in the wound state. Also results in lowering the commercial value of the cone type container.

As one solution to this problem, the applicant has disclosed Japanese Patent Publication No.
In No. 40858, a bonding solution is interposed between the outer end portion of the sugar cone formed by wrapping the baked sheet material and the cone body, and the outside of the winding is formed by utilizing the residual heat of the sheet material. We have proposed a means of firmly joining the end to the main body, and have greatly contributed to maintaining the shape of the cone-shaped ice cream container containing sugar.

[0009]

SUMMARY OF THE INVENTION In a cup-shaped container containing sugar, which is press-formed using a concave-convex mold, a strain is generated mainly at a strained portion of a fired sheet-like material at the time of press forming due to excessive forming. This tendency tends to be derived from the periphery of the opening of the cup-shaped container. The present invention suppresses the occurrence of deformation on the cup-shaped container as much as possible by forming a reinforcing portion integrally with the periphery of the opening of the cup-shaped container when the cup-shaped molding is performed, in which the deformation expansion phenomenon is clearly expressed.

When the shape of the curved connecting portion 4 is circular, the amount of the connecting curve between the periphery of the opening of the main body and the portion of the downward annular lip 3, that is, the radius of curvature is uniform at various portions of the peripheral portion. The amount of deformation that rises from the main body 2 is averaged in various places, and in the cup-shaped container, the deformation derived after a long period of time is also substantially uniform in each place, and the variation in the shape of the container 1 itself is minimized. The opening of the container is made tough.

Next, a method for producing the cup-shaped ice cream container will be described with reference to the drawings, FIG. 4 and FIG.
The powdered milk-like material containing a relatively large amount of sugar is supplied between both plates of a baking apparatus composed of a heating substrate and a baking plate which opens and closes the substrate. The fired sheet material still retains a residual heat of about 100 ° C., has sufficient flexibility and ductility, and has a sufficient wall thickness.

In the case of a container having a circular shape as viewed in plan, that is, a circular material far larger than the circular opening of the container, the material is punched and cut from a sheet-like fired material in advance according to the plan shape of the intended cup-shaped container. Then, this circular punched sheet material,
The male and female molds to be combined are supplied to the upper surface of the female mold. When the container has an oval opening, the sheet material is punched and cut into a large oval, and when the container has an elliptical opening, the sheet material is punched and cut into a large oval.

The fired sheet material A previously punched and cut into a predetermined size and shape is provided with a concave portion 12A on the joining surface of the mold.
Is supplied to a female mold 11A in which an annular ridge 13A is formed in a protruding shape on the joining surface of the mold in a continuous manner at the periphery of the concave portion, and the mold is joined to the female mold 11A. 15A on the surface

Thus, the downward annular lip 3 connected to the periphery of the opening of the container body 2 is integrally formed, and the cut surface 5 appears on the lower end surface of the downward annular lip 3 (see FIG. 3).

The cup-shaped main body and the downward lip can be formed in series, so that the shape is accurate and the speed of operation can be ensured. Furthermore, since the cut surface (cut surface 5 of the product) expressed on the sheet-like material itself is expressed on the tip surface of the downward lip, that is, the downward surface that is most invisible to the human eye, the appearance of the product should be good. Can be.

In another manufacturing method, the above-mentioned baking apparatus is used for baking and still maintaining the residual heat of about 100 ° C.
A sheet-like fired material having sufficient flexibility and extensibility and having a sufficient thickness is immediately provided with a concave portion 1 on the joining surface of the mold.
2B is supplied onto a female mold 11B in which an annular ridge 13B is formed in a protruding shape on the joining surface of the mold so as to be connected to the peripheral edge of the concave portion, and the joining surface of the mold is connected to the female mold 11B. Convex part 15B
The male mold 14B is formed by connecting the outer peripheral edge of the convex portion to form an annular groove portion 16B and integrally forming a downwardly cutting annular edge portion 17 integrally with the outer peripheral edge portion of the annular groove portion 16B. .

The sheet-like material A is sandwiched and pressed between the concave portions 12B and the convex portions 15B of the two dies 11B and 14B to form the cup-shaped main body 2 of the container 1, and at the same time, the annular ridges of the two dies. In the process of fitting 13B and annular groove 16B,
A downward annular lip 3 connected to the periphery of the opening of the main body 2 is integrally formed, and the outer peripheral portion of the lip 3 is formed simultaneously with the molding of the annular lip 3 by fitting the male mold 14B with the female mold 11B. The surplus portion is cut and removed at the downward edge 17 of the male die 14B, so that the cut surface 6 appears on the lower side surface of the downward annular lip instead of the cut surface 5 (see FIG. 3). ).

In the process of forming the cup-shaped body and the downward lip product, the surplus outer peripheral portion of the sheet material is cut and removed at the same time. Therefore, a series of workability of forming and cutting and removing the sheet material is as follows. In particular, it can greatly contribute to the efficiency of work, and does not take unnecessary consideration of the process of feeding the sheet-like material to the molding die.In this respect, the mechanism is simplified and the work is speeded up. There are many things to look at. Further, since the cut surface 6 of the product is locally expressed on a part of the side surface of the lower portion of the downward lip, the appearance of the product can be kept good in this respect.

[0032]

The cup-type ice cream container according to the present invention has a sugar content by integrally forming an inverted U-shaped downward annular lip extending from the main body on the entire periphery of the opening of the cup main body. In the container, deformation of the container derived from its hygroscopicity, particularly distortion occurring around the opening of the container, and deformation can be more effectively prevented, and the progress speed of the deformation is suppressed at least for a long period of time. can do.

Conventionally, in a cup-shaped ice cream container,
Mixing a large amount of sugar promotes its hygroscopic deformation, and it was impossible to provide a large amount of this type of cup-type container to the market as a product. With the slightest modification attached, firstly, the occurrence of frequent deformation at the center of the opening of the container is suppressed, and due to the change in the amount of sugar mixed in with a large amount of sugar, the cup-shaped ice cream container containing sugar, which changes its flavor, can be sufficiently marketed. It became possible to supply.

The presence of the downward annular lip can also reinforce the periphery of the container opening where the most damage occurs in the container, thereby reducing the occurrence of damage that degrades the commercial value of the container itself. It can be effectively prevented. Of course, by combining this pair of cup-shaped containers, it can be positively used as ice monaka, and can greatly contribute to diversification of ice products.

When the cup-shaped container is used as an ice monaca, each opening of the pair of containers is formed by bending means, so that a cup-shaped container having a desired uniform opening can be easily manufactured. In addition, the finish of the opening of the cup-shaped container is also beautiful, and the appearance of the ice monaca itself, which is combined with the two openings, is good, and the product homogeneity is added to the result, increasing the commercial value be able to.

Further, in the present invention, the surplus cut portion of the container edge at the time of molding is naturally performed by the downward annular lip portion. Since the vertical cutting method can be realized, the cutting operation in the manufacturing process becomes easy, and the position of the cutting surface on the side surface of the product or the lower surface of the downward lip, avoiding the surface position on the product, and the cutting surface thereof. The finished state is also several steps superior in terms of beauty and appearance as compared with conventional products.
