Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rice filling device for filling rice into a cup-shaped container.

[0002]

2. Description of the Related Art Sauce rice, such as curry rice and Hayashi rice, provided at a lunch box or a convenience store, is a disposable type dish in the shape of a small oval plate in a plan view so that the rice and the sauce are not mixed. Which is provided in a container partitioned into a rice storage portion and a source storage portion via a partition wall. However, such a deep dish-shaped container is suitable for eating on a table, but it is difficult to hold it with one hand, and even if it is slightly inclined, the sauce will spill, so hold the container with one hand Was unsuitable for meals at the restaurant. For example, it is not suitable for sitting on a park bench or a car seat, or standing or walking while eating.

[0003] The applicant of the present invention has proposed a sauce-hung rice that can be easily and easily eaten by filling a cup-shaped container with rice and hanging the sauce (Japanese Patent No. 2976970). Reference). Also,
In this sauce hung rice, rice filled in a container,
By forming a cavity that extends from the surface to the back of the container and hanging the sauce so that the sauce is filled in this cavity, it is possible to prevent the problem that only rice remains at the end of the meal It is configured.

[0004]

By the way, in the sauce-hung rice described in the above publication, as a method for filling rice into a container, after filling the container with rice, a hollow portion of the rice is formed using a rod-shaped member. However, when the hollow portion is actually formed in this way, there is a problem that the rice in the vicinity of the hollow portion is crushed by the rod-shaped member, and the texture of the rice is reduced. Also, in this sauce-hung rice, it is necessary to form a space for filling the sauce in the upper part of the container. There is a problem that it is easy to fluctuate and it takes a lot of time to become skilled so that an appropriate amount can be filled.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rice filling device which can easily fill rice in a state where a cavity is formed without lowering the texture of the rice, and which can easily perform constant filling of rice. is there.

[0006]

The rice filling device according to the present invention fills rice into a cup-shaped container so that a cavity extending from the surface to the back is formed. A rice filling device for forming a bottomed substantially cylindrical outer surface forming portion for forming rice in a shape that can be loaded into the container, and extending from the bottom surface of the outer surface forming portion toward the opening side, A mold having a cavity molding part for molding a cavity with respect to the rice filled in the outer surface molding part is provided.After filling the mold with rice, the rice in the mold is transferred into the container in an inverted manner. Instead, the container is filled with rice.

In this rice filling device, a cavity is formed in the rice by the cavity molding portion in a state where the rice is filled in the mold, and the cavity is formed by transferring the rice to a container. Since the container is filled with rice, the workability is slightly reduced as compared with the case where the cavity is formed after filling the container with rice, but at the time of forming the cavity, the rice is crushed. As a result, it is possible to surely prevent the deterioration of the texture of rice.

When the hollow portion is formed in the center of the rice, the outer surface forming portion and the hollow portion forming portion are provided independently of each other. However, when the hollow portion is formed on the side portion of the rice, In this case, a part of the outer surface forming part constitutes the cavity forming part, and when an annular cavity is formed between the rice and the peripheral wall of the container, the entire outer surface forming part forms the cavity forming part. Will do.

The volume of the internal space of the mold can be set to an arbitrary volume as long as it is equal to or larger than the volume of rice to be filled in the container. Is filled almost completely, the amount of filling varies slightly depending on the degree of filling of the rice into the mold, but it is possible to easily fill a rice with a relatively appropriate capacity.

When a tapered fitting surface is formed on at least the upper outer peripheral surface of the mold so that the upper portion of the container fits outside,
When the rice is transferred from the mold to the container, the container can be externally fitted deep enough to the upper part of the mold, and the mold and the container can be turned upside down. Transfer workability can be improved.

[0011] Since the filling of the mold into the rice is performed by softly dressing, when the rice is transferred from the mold to the container, the rice is hardly clogged in the mold, but a part of the rice is clogged. Since it is conceivable that the resin remains in the mold, it is preferable to provide an extrusion means for extruding the rice in the mold.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. First, the sauced rice will be described. As shown in FIGS. 1 and 2, the sauce-hung rice 1 is housed in a cup-shaped container 2 that can be gripped with one hand, and is filled with rice 3 that has been cooked and cooked on it. The opening of the container 2 is closed with a lid 5. However, the lid 5 may be omitted.

In such a sauce-hung rice 1, since the rice 3 and the sauce 4 are housed in a cup-shaped container 2 which can be held by one hand, the sauce-hook rice is held in a state where the container 2 is held by one hand. 3 can be eaten. In addition, since it is placed in a cup-shaped container 2, it can be handled easily as soft drinks in a cup, and it has a large degree of freedom of holding, so it can be used in places without a table or other table. It is possible to eat without getting tired of arms and fingers. For example, it is suitable for sitting on a park bench or a car seat, or standing or walking while eating. Especially when eating in a car,
It is preferable because it can be set in a cup holder of a car.

The sauce-hung rice 1 can be applied to any food, such as curry rice, hayashi rice, mabodon, and egg-filled rice bowl, as long as the source 3 and the ingredients 6 are hung on the rice 3 and eaten. it can. Sauce 4 is curry rice, Hayashi rice, Mabo bowl roux, or Japanese style soup with egg and toji bowl. Ingredient 6 is pre-mixed with sauce 4 and can be hung on rice 3 with sauce 4. Good, or topping can be performed separately from the source 4. Moreover, you may comprise so that only the main tool 6 may be topped.

When the tool 6 is configured to be topped,
Changing only the tool 6 is preferable because the type of the source hanging rice 1 can be changed while using the same source 4 and the menu can be easily changed or increased. For example, tool 6
By using beef cutlet, chicken cutlet, croquette, hamburger etc., without changing source 4, beef cutlet curry, chicken cutlet curry, croquette curry,
We can provide several kinds of sauce hung rice such as hamburger curry. Moreover, since the source 4 can be configured so that no solid matter enters, it is also possible to supply the source 4 from a nozzle, for example, as in a soft cream or soft drink supply device, and in a fast food store or a convenience store, etc. It becomes possible to efficiently provide the rice 1 with sauce.

The container 2 is formed in a bottomed frustoconical shape having a draft angle formed by reducing the diameter of the peripheral wall portion toward the lower side. As the material of the container 2, it is possible to use a synthetic resin material such as polystyrene, polyethylene, vinyl chloride, polypropylene, vinylidene chloride, polyamide, polycarbonate, polyethylene terephthalate, its foam, paper, or the like. Further, a laminate structure composed of these materials may be used, or a laminate of synthetic resin films on the surface may be used. In particular, when a synthetic resin foam is used, the heat insulating property can be improved, so that it can be easily grasped by hand, and since the heat retaining property is excellent, the temperature of the sauce-hung rice 1 can be maintained for a relatively long time. Moreover, in order to improve heat insulation and heat retention, the wall of the container 2 may be configured to have a double structure having a heat insulating space.

A vertically extending cavity 7 is formed near the bottom plate of the container 2 at the center of the rice 3 in a state where the rice 2 is filled, and an annular cavity 8 is formed between the container 2 and the peripheral surface of the rice 3. Is formed up to the vicinity of the bottom plate of the container 2. The cavities 7, 8 are formed by filling rice 3 with a rice filling device 10 described later. When the cavities 7 and 8 are formed in this manner, the sauces 4 are also filled in the cavities 7 and 8, so that the problem that only the rice 3 remains at the end of the meal can be prevented. That the sauce 4 can be easily entangled with the rice 3;
The rice 3 and the sauce 4 can be arranged in a separated state, and effects such as improvement in appearance can be obtained.

The number of cavities 7 can be set arbitrarily. Only one cavity 7 may be provided as shown in FIGS. 1 and 2, or a plurality of cavities 7 may be provided. Further, as shown in FIG. 2, it may be formed to have a bottomed shape, or may be formed to penetrate from the surface of the rice 3 to the bottom plate of the container 2. Further, the formation position of the cavity 7 can be arbitrarily set, and as shown in FIG. 2, it may be provided at the center of the rice 3 or may be provided at the outer periphery or near the outer periphery.
Furthermore, the cross-sectional shape of the cavity 7 can be set arbitrarily.
As shown in FIG. 2, it may be formed in a substantially circular cross section, or may be formed in a heart-shaped or star-shaped cross section. Further, the volume of the cavity 7 is set to be substantially the same as or slightly larger than the amount of the source 4 to be filled in the container 2 so that the source 4 does not cover the upper surface of the rice 3 to improve the appearance. This is also possible. Furthermore, when the size of the cavity 8 is set to be sufficiently large, the cavity 7 can be omitted.

Next, in the rice 1 with sauce, a rice filling device 10 for filling the container 2 with the rice 3.
Will be described. The rice filling device 10 according to the present invention comprises:
Basically, there is provided a molding die 11 having a cavity molding portion 15 having a shape and size adapted to the cavity portion 7.
After the rice 3 is filled, the container 2 is fitted over the molding die 11 in an inverted manner, and the molding die 11 is turned upside down together with the container 2 in this state, and the rice 3 is transferred to the container 2. .

As shown in FIGS. 3 and 4, the rice filling device 10 comprises a substantially cylindrical mold 11 having a bottom and a mold 11.
And a handle 12 fixed to the lower part of the cradle. Mold 1
1 includes a peripheral wall 13, a bottom wall 14, and a cavity forming portion 15,
It is integrally formed of a synthetic resin material, a metal material, or the like. It is preferable that the molding die 11 be made lightweight because it is held and operated with one hand as described later. When it is made of a metal material, it is made of an aluminum alloy or a thin stainless steel plate. Is preferred. Further, it is preferable to form a coating layer made of Teflon (registered trademark) on at least the inner surface of the mold 11 in order to prevent the rice 3 from adhering. The outer surface forming portion of the forming die 11 is constituted by the inner surface side portions of the peripheral wall 13 and the bottom wall 14.

The inner surface of the peripheral wall 13 can be formed in an arbitrary cylindrical shape. However, in order to make it easier to take out the filled rice 3, the inner surface is formed to have a draft with a diameter decreasing toward the lower side. Is preferred. The cross-sectional shape of the inner surface of the peripheral wall 13 may be circular, heart-shaped, star-shaped, polygonal, or the like.

The bottom wall 14 of the mold 11 is integrally formed with a bottomed cavity forming portion 15 extending upward. The forming position of the cavity forming portion 15 is provided corresponding to the forming position of the cavity portion 7, and the cavity forming portion 15 is formed in a shape suitable for the shape of the cavity portion 7. It is preferable that the cavity forming portion 15 is formed in a shape in which a draft is formed such that the upper end side is reduced in diameter. Further, the cavity forming section 15 can be formed of a member different from the molding die 11. Further, one or a plurality of through holes are formed in the bottom wall 14, and through the through holes,
When the rice 3 filled in the mold 11 is turned upside down and taken out, air may be introduced between the rice 3 and the bottom wall 14 so that the rice 3 can be smoothly transferred to the container 2. .

Although the volume of the internal space 16 of the mold 11 can be set arbitrarily, if the volume of the rice 3 to be filled in the container 2 is set to be substantially the same as that of the rice 3, the mold 3 is filled with rice 3 completely. It is preferable because an appropriate amount of rice 3 can be measured. The rice 3 molded by the molding die 11 can be set to any size as long as it can be accommodated in the container 2. However, in order to improve the texture of the rice 3, the mold 3 is softly filled with the rice 3. Therefore, when the rice 3 is transferred from the mold 11 to the container 2, the shape of the rice 3 is changed. Somewhat crumble. Therefore, the maximum diameter of the inner surface of the peripheral wall 13 of the molding die 11 can be set to be slightly larger than the minimum diameter of the inner surface of the container.

The upper half of the peripheral wall 13 of the molding die 11 is formed with a tapered fitting surface 17 which is reduced in diameter upward and fits the upper inner surface of the container 2. The upper part (opening side portion) of the container 2 can be externally fitted with the container 2 in an inverted state. Mating surface 17
A longitudinal groove 18 extending in the axial direction of the peripheral wall 13 is formed in
The vertical groove 18 prevents the inner surface of the container from being in close contact with the fitting surface 17, so that the container 2 can be easily removed from the mold 11. An annular step 19 is formed at the lower end of the fitting surface 17, and the upper end of the container 2 is locked by the step 19, so that the container 2 is excessively inserted into the fitting surface 17. Has been prevented. However, the fitting surface 17 can be omitted.

At the lower part of the peripheral wall 13 of the molding die 11, the mounting holes 2 are formed.
0 is formed, and the handle 12 has its base end mounted in the mounting hole 20 and fixed by screws 23. In the vicinity of the base end of the handle 12, there is formed a balance adjusting portion 21 extending upward with a gap for inserting the container into the fitting surface 17, and extends outward substantially horizontally at the upper end of the balance adjusting portion 21. The handle part 22 is formed integrally. In addition, handle 12
May extend straight from the mounting hole 20 to the side, but in this case, a sufficient gap between the handle portion and the table cannot be secured with the rice filling device placed on the table or the like, and the hand It is difficult to grip the handle with the mold 1
Since the operability of (1) is reduced, it is preferable to configure the crank shape as described above. However, the handle 12 is not always an indispensable member, and can be omitted when the mold 11 is directly gripped and used by hand.

Next, a method for filling rice 3 using the rice filling device 10 will be briefly described. First, FIG.
As shown in (a), the cooked rice 3 is substantially completely set in the internal space 16 in the molding die 11 using rice scoops or the like. At this time, it is necessary to put the rice 3 up to the lower end of the internal space 16 so that the rice 3 is filled. However, it is preferable to put the rice 3 lightly because the rice 3 is crushed when pressed firmly.

Next, as shown in FIG.
After the upper part of the container 2 is fitted over the fitting surface 17 of the container 1 with the container 2 turned upside down, as shown in FIG.
At the same time, the container 2 is turned upside down, and the rice 3 in the mold 11 is transferred to the container 2.

Next, the container 2 is pulled out from the fitting surface 17 so as not to spill the rice 3, and the rice 2 is filled in the container 2. In the rice 3 thus filled, the cavity 7 is formed at a position corresponding to the cavity forming portion 15 and the cavity 8 is formed between the rice 3 and the peripheral wall of the container 2.

Next, another embodiment in which the configuration of the rice filling device 10 is partially changed will be described. (1) The rice filling device 10 may be provided with an extruding means for extruding the rice 3 filled in the mold 11.
It is possible to employ any extrusion means. For example, as in a rice filling device 10A shown in FIG. 6, instead of the molding die 11, a bottomed first molding die 30 having a peripheral wall 13 and a second molding die 31 having a cavity molding portion 15 and a bottom wall 14 are provided.
