Description:

TECHNICAL FIELD

The present invention relates to a container that can store and distribute a plastic substance such as soft serve ice cream and a distributing device thereof.

BACKGROUND ART

Conventionally, there are provided containers that can store and distribute a plastic substance such as soft serve ice cream in Japanese Laid-Open Patent Publication No.H10-502251 and Registration of Utility Model No.2568808. Particularly, these approaches are characterized by almost completely discharging a content food by deforming the same into a flat shape through pressurization by providing the container with a thread groove.

However, conventional methods required complicated works such that a container for distributing plastic food such as the soft serve ice cream is provided with the thread groove. Namely, it was for easily crushing the container when distributing and for preventing the plastic food such as the soft serve ice cream from staying inside after crushing.

There are also two methods for manufacturing the soft serve ice cream composed of a plurality of components using a distributing container in the use of a conventional container.

First method is a method of previously injecting the cream composed of a plurality of components inside the distributing container and then distributing the cream from one distributing container. This method has an advantage that a distributing step comprises a single process. However, the method has had a problem that the soft serve ice cream is already mixed when distributing it, and thereby combination of mixture of the soft serve ice creams cannot be decided.

Second method is also a method of distributing one soft serve ice cream from a first distributing container and thereafter distributing the other soft serve ice cream composed of a different component using the first distributing container and the second distributing container containing one of a plurality of components respectively. In this case, combination of mixture can be decided when distributing the soft serve ice cream. However, the method has had problems that because a distribution is performed with the first distributing container and thereafter the other distribution is performed with the second container, it takes time for distributing and further time difference occurs in distributions of the first and second distributing containers.

Objects of the present invention are to provide a simpler container for distributing plastic substance such as soft serve ice cream and to further provide a container capable of determining combination of a plurality of plastic substances when distributing and thereafter distributing the plurality of plastic substances simultaneously and a distributing device thereof.

BEST MODE FOR CARRYING OUT THE INVENTION

In other detailed constitution of the present invention, advantages and features are made clear by embodiments described below in reference to accompanied drawings.

A distributing container 1 according to the present invention is constituted of a circular bottom face 2, a side face 4 perpendicular to the bottom face 2, and a sword-guard-shaped portion 6 which is protruded perpendicular to an end of the side face and parallel to the bottom face 2, and is provided with an opening 8 at the center of the bottom portion 2.

Wall thickness of the bottom face 2 is between 0.2 mm and 0.5 mm inclusive. The shape of the opening is reflected on a plastic food by forming a thick bottom face 2. Namely, when the shape of the opening is a star shape, the plastic food distributed from the distributing container is also the star shape. The wall thickness of the side face is between 0.1 mm and 0.3 mm inclusive. By forming a side face of the wall thickness of 0.1 mm or more, even though the container is filled with the plastic food, the container does not bulge. By forming a side face of the wall thickness of 0.3 mm or less, the container can be easily crushed and further the container becomes almost flat when being crushed, thereby the wall thickness of the sword-guard-shaped portion is preferably between 0.35 mm and 0.55 mm inclusive. By forming the sword-guard-shaped portion of the wall thickness of 0.35 mm or more, it becomes easy to seal the opening, and by forming the sword-guard-shape portion of the wall thickness of 0.55 mm or less, it is possible to simultaneously form the side face thinner.

FIG. 2 shows an embodiment of the case that the container is divided. In distributing containers 10 and 12 according to the present invention, a flat plate side face 16 erects perpendicular to a linear part of a half-moon-shaped bottom portion 14. While, an arcuate side face 18 erects perpendicular to a circular-arc part of the half-moon-shaped bottom portion 14. The flat plate side face 16 and the arcuate side face 18 are respectively jointed at both ends perpendicular to the bottom portion 14. A linear sword-guard-shaped portion 22 is further protruded parallel to the bottom face at the side of an opening opposite to a bottom side of the flat plate side face 16. While, an arcuate sword-guard-shaped portion 20 is protruded parallel to the bottom face at the side of the opening opposite to a bottom side of the arcuate side face 18.

In addition, the bottom portion 14 is provided with a star-shape opening 24 and any of the star-shaped openings are formed so as to abut on the linear part of the bottom portion 14.

Though material of the distributing container is not particularly limited, the material may be a hard-type thin synthetic resin such as polypropylene, polyethylene, polystyrene, polyvinyl chloride, ethylene-vinyl acetate copolymer, and high-density polyethylene or cold resistance grade thereof, wherein wall thickness is between 0.2 mm and 0.5 mm inclusive. A corn-based biodegradable resin or other biodegradable resins may be also used. The wall thickness of the flat plate side face 16 and the arcuate side face 18 is preferably between 0.1 mm and 0.3 mm inclusive, and the wall thicknesses of the arcuate sword-guard-shaped portion 20 and the linear sword-guard-shaped portion 22 are desirably between 0.35 mm and 0.55 mm inclusive. The wall thickness of the bottom portion 2 is between 0.2 mm and 0.5 mm inclusive. By forming the container of the wall thickness of this size, the distributing container can be easily crushed after distributing soft serve ice cream and can be also prevented from bulging when filling the soft serve ice cream.

Such constitution enables the container according to the present invention to be arranged as two containers, compared to normally one columnar container, and also enables two kinds of the soft serve ice cream to be arranged and distributed simultaneously. The openings for pushing out the soft serve ice cream are provided adjacently, thereby the two kinds of the soft serve ice cream are allowed to come close to each other at the openings and to be distributed. Two kinds of soft serve ice cream can be mixed simultaneously, thereby when there are five kinds of soft serve ice cream, fifteen combinations are possible. In this regard, the soft serve ice cream is an example and the plastic food is not limited to this soft serve ice cream and the container can intend food having plasticity such as mousse, bavarois, and whipped cream.

Then, a distributing container of second embodiment according to the present invention is shown in FIG. 3. Difference from the distributing container of the first embodiment is in arrangement of an opening 26. In the second embodiment, the opening 26 is arranged at the center of the bottom face 6. Such constitution enables the soft serve ice cream to be distributed independently when distributing.

FIG. 4 shows a bottom view of the distributing container illustrated in FIG. 1, which is viewed from the bottom face. An opening 8 is shown at the center of the bottom face 2.

FIG. 5 shows a view when the containers shown in FIG. 2 unite. A bottom face and an opening are symbolized by 14 and 24, respectively. The end of the bottom face is shown by a line segment 15, and an abutting part of line segments in the openings is minimized.

FIG. 6 shows a bottom view when trisecting a container. Openings 30 are shown on bottom faces 28 and border lines are symbolized by 29. Three combinations are possible. In the case of five kinds of soft serve ice cream, thirty-five combinations are possible.

FIG. 7 shows a bottom view when dividing the container into four quarters. Openings 34 are shown on bottom faces 32 and border lines are symbolized by 33. In the case of five kinds of soft serve ice cream, seventy combinations are possible.

Further, FIG. 8 shows a container holder 35 for pressing by arranging the distributing container according to the present invention. The container holder 35 is provided with an opening 38 on a bottom face 36 and the end of the container holder is provided with a cylindrical side face 40. In addition, a partitioning plate 42 is protruded perpendicular to the bottom face, thereby the container holder 35 is divided into two compartments.

Two distributing containers according to the present invention can be fixed in a space of one normal distributing cantainer.

The opening 38 is also on the bottom face 36, thereby the soft serve ice cream is allowed to be pushed out from the opening. These partitioning plates of the container holder are further formed for trisection or quadrisection, thereby a container holder suitable for the container corresponding to them can be formed.

FIG. 9 shows a pushing equipment 44 of a pushing device. The pushing euipment 44 is constituted so that an entire shape is columnar and so that a slit 48 perpendicular to a bottom face corresponding to the partitioning plates of the container holder is provided on the lower part, thereby to press only the container arranged on the container holder without pressing the partitioning plate. Diameter of the pushing equipment 44 is almost the same as diameter of the plastic food distributing container, and the length of the pushing equipment 44 is larger than that of the plastic food distributing container.
