Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to a sushi rice forming device for forming sushi rice into a sushi rice shape, which is used when an amateur makes a sushi rice at an ordinary household.

[0002]

[Prior art]

 Conventionally, grip forming devices that have been used by amateurs to make grips in ordinary households, etc., are fitted with a lower mold in the outer frame, and then inserted into a recess defined by the outer frame and the lower mold. Pour the sushi rice in the lower frame, outer frame, and upper mold by putting the sushi rice into the outer frame until the upper edge of the frame is flat, then put the upper mold into the outer frame and push it down until it matches the lower mold. It was configured to be formed in an inclined shape.

[0003] A gripper having such a structure is generally known. When a lower mold is fitted into an outer frame, the volume of a recess defined by the outer frame and the lower mold is increased. It is designed to be about twice the volume formed by the lower mold and the upper mold in the outer frame. As a result, the formed grip was too compressed, resulting in a marked difference in texture from that of the sushi craftsman's hand.

[0004] As a solution to this problem, Japanese Utility Model Publication No. 7-18311 and Japanese Utility Model Publication No. 7-35575 disclose that anybody can form a sushi sushi having the same texture as a sushi craftsman's hand. As a result, the volume of the recess defined by the outer frame and the lower die is designed to be smaller than about twice the volume formed by the lower die and the upper die in the outer frame. Is disclosed.

[0005]

[Problems to be solved by the invention]

 However, even with the gripper forming apparatus having the structure disclosed in the above publication, if the amount of sushi rice that a person puts in the mold is large, the texture of the gripping handle is also excessively compressed at the time of molding. A different problem arises in that the flavor is also impaired. In addition, the conventional squeezer does not take into account the air contained in the squeeze after molding, so the molded squeeze does not contain adequate air, and it takes time. There is also a problem that the texture becomes worse and the flavor is impaired.

[0006] Furthermore, conventional grip forming devices including a grip forming device used for business use have been formed of wood such as cherry blossoms and tsubaki. This is because the sushi rice is easily separated from the mold. Some of the onigiri shaping devices for shaping onigiri are made of a resin composition such as polyethylene. However, sushi rice is more sticky than ordinary rice due to the sugar content in sushi vinegar. For this reason, wood and resin compositions used in conventional grip-making machines and onigiri-molding machines still have the problem that sushi rice sticks, the sushi rice does not release easily, and it takes time to clear up. was there. In consideration of this problem, a method of adding salad oil or the like to sushi rice in advance is conceivable, but adding salad oil reduces the flavor.

[0007] In order to solve these problems, the present invention can form a textured grip that is moderately airy and has a good texture, such as a gripped grip held by a sushi craftsman, and does not stick sushi rice. However, an object of the present invention is to provide an inexpensive and simple forming device.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the grip forming apparatus of the present invention has a lower mold and an upper mold fitted into an outer frame, and has a shape surrounded by the outer frame, the lower mold, and the upper mold. The lower die includes a forming table for forming a bottom surface of the grip, and a projection provided on an upper surface of the forming table, wherein the upper die includes the forming table. A pressing portion having a shape corresponding to the shape of the molding table, which presses the sushi rice, and the outer frame has a fitting portion in which the lower mold table and the upper mold pressing portion are fitted. Wherein the lower mold, the upper mold, and the outer frame are formed of a resin composition containing a fluororesin.

According to this configuration, a depression is formed on the bottom surface of the grip after molding by the projection of the lower die, and the depression appropriately contains air in the grip after molding. For this reason, the formed gripped sushi has the same texture as that held by a sushi craftsman, and the texture does not change and the flavor is not impaired even after a lapse of time after molding. Further, since the lower mold, the upper mold, and the outer frame are formed of a resin composition containing a fluororesin, rice does not stick. Therefore, the sushi rice can be released from the mold more easily than the conventional sushi rice forming machine, and it does not take much time to clean up.

Further, it is preferable that the resin composition is a polypropylene resin composition containing 2 to 15% by mass of polytetrafluoroethylene as a fluororesin. Particularly preferred as the resin composition is a polypropylene resin composition containing 7% by mass of polytetrafluoroethylene.

[0011] With this configuration, the same effect as that of the case made from only the fluororesin, that is, the effect of preventing sushi from sticking to each other is realized, and at the same time, the grip is lighter and easier to handle than that made from only the fluororesin. A molding machine can be provided at low cost.

[0012]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

The grip forming apparatus according to the present embodiment includes a lower mold, an upper mold, and an outer frame, and forms the grip by fitting the lower mold and the upper mold in the outer frame. I do. FIGS. 1 to 3 show a lower die, an upper die, and an outer frame, respectively, which constitute a grip forming apparatus according to the present embodiment. In FIG. 1, (a) is a top view of the lower mold, (b) is a front view of the lower mold, and (c) is a side view of the lower mold. 2A is a top view of the upper mold, FIG. 2B is a front view of the upper mold, and FIG. 2C is a side view of the upper mold. 3A is a top view of the outer frame, FIG. 3B is a sectional view taken along line AA of FIG. 3A, and FIG. 3C is a side view of the outer frame.

As shown in FIG. 1, the lower mold 1 is provided with two forming tables 12 for forming sushi rice in a sushi rice shape (shape of a bottom portion of sushi rice) on a substrate portion 11. It is configured. At the center of the upper surface of the molding table 12, a projection 13 is provided which is disposed substantially parallel to the side surface 12a of the molding table 12. The protrusions 13 form a depression on the bottom surface of the grip after forming to allow air to be absorbed without gripping. In this way, by providing a dent that allows air to be absorbed into the sushi, anybody can make a sushi that has the texture of a sushi craftsman's hand. Even with the passage of time, the texture of the squeezed sushi remains unchanged and the flavor is not impaired.

Further, both ends 12 b of the upper surface of the molding table 12 are formed slightly higher than other portions of the upper surface. Further, on the upper surface, a gentle inclined portion 12c is formed which becomes lower from the central portion toward one side surface (the left side surface 12a in the figure in the present embodiment).

In the present embodiment, the length d1 of the molding table 12 is set to 56 mm and the width d2 is set to 25 mm, and the molding table 12 is designed so that it can be molded to the same size as a general grip. Further, the height d3 of the molding table 12 from the substrate 11 was 10 mm, and the height d4 of both ends 12b of the upper surface from the substrate 11 was 15 mm. The length d5 of the protrusion 13 was 25 mm.

On the other hand, the upper die 2 shown in FIG. 2 is configured such that a pressing portion 22 for pressing sushi rice on the forming table 12 of the lower die 1 at the time of squeezing is provided on the substrate portion 21. I have. A handle 23 is provided on the back surface of the substrate portion 21 (the surface on which the pressing portion 22 is not provided). The pressing portion 22 has a shape corresponding to the molding table 12 of the lower die 1. Further, in order to provide a pressing margin in the pressing portion 22, the upper surface 22a is formed in a smooth concave shape so that the height in the pressing direction is higher at the edge portion than at the central portion. By providing such a pressing margin, even if the amount of sushi rice to be served is small, it is possible to form a grip that is properly tightened.

The height of the pressing portion 22 from the substrate portion 21 in the present embodiment is such that the height d6 to the highest edge portion is set to 22 mm, and the height d7 to the lowest center portion is set to 15 mm. I have. The length and width of the pressing portion 22 are set to d1 and d2, similarly to the molding table 12.

As shown in FIG. 3, the outer frame 3 is provided with a through hole as a fitting portion 31 into which the molding table 12 of the lower die 1 and the pressing portion 22 of the upper die 2 are fitted. The fitting portion 31 is formed so as to correspond to the shapes of the molding table 12 and the pressing portion 22, and thus has a length d1 and a width d2. As shown in FIG. 4, the height d8 is set between the molding table 12 and the pressing portion 22 when the molding table 12 and the pressing portion 22 are fitted into the fitting portion 31 of the outer frame 3. It is set so that an appropriate space (thickness d9, d10 in the height direction) is formed. In the present embodiment, d8 is 50 mm, d9 is 13 mm, and d10 is 25 mm.

Further, the lower mold 1, the upper mold 2, and the outer frame 3 are made by adding 7% by mass of polytetrafluoroethylene (PTFE), which is a fluororesin, to polypropylene (PP). It is formed by injection molding using materials. Sushi rice is more sticky than ordinary rice because the sugar content of sushi vinegar covers the surface of the rice grains. For this reason, in the materials used in the conventional gripper (wood such as cherry blossoms and tsubaki, and resin compositions such as polyethylene), sushi rice sticks to the gripper and the grip after forming is formed. The sushi was not easily separated from the mold, and it took time to clear up afterwards. On the other hand, when the resin composition obtained by adding 7% by mass of PTFE to PP is used as in the case of the gripping device of the present embodiment, the sushi rice does not stick to the forming device, so that the sushi rice does not stick to the forming device. The mold can be easily separated from the mold, and the cleaning can be done simply by washing with water. In addition, it is conceivable to manufacture a molding device without gripping only with PTFE in consideration of only good mold release and easiness of putting away the back, but in this case, the cost is increased. Further, the specific gravity of PTFE is 2. As a result, the handgrip forming device made only of PTFE is heavy and difficult to handle. On the other hand, in the case of a material obtained by adding 7% by mass of PTFE to PP used in the present embodiment, the cost is low and the specific gravity is about 1.0. Can be made.

Next, a procedure for forming a grip by the grip forming apparatus according to the present embodiment will be described. First, the molding table 12 of the lower mold 1 is fitted to the fitting portion 31 of the outer frame 3. Next, sushi rice is poured into the recess defined by the lower mold 1 and the outer frame 3 up to the height of the upper edge of the outer frame 3. Next, the pressing portion 22 of the upper die 2 is fitted into the fitting portion 31 of the outer frame 3 to press the sushi rice, and the sushi rice is formed into a shape surrounded by the lower die 1, the upper die 2 and the outer frame 3. After that, the sushi rice formed in the shape of a sushi is removed from the squeezer and the fish and other ingredients are placed on it to complete the sushi rice.

As described above, the grip forming apparatus according to the present embodiment is formed of a material in which the protrusion 13 is provided on the molding table 12 of the lower mold 1 and 7% by mass of PTFE is added to PP. This makes it possible to form a textured grip that contains a moderate amount of air, similar to a grip gripped by a sushi chef, and that the sushi rice does not stick and is easy to clean up.

Although the grip forming apparatus of the present embodiment is configured so that two grips can be formed in a single operation, the number of the forming table 12, the pressing portions 22, and the fitting portions 31 is limited. Since it is optional, the number of grips formed in one operation is not limited to two.

Further, the lower mold 1 can be put out in front of a person who eats the food while leaving the grip on the upper part. Thereby, it is possible to save the trouble of transferring the hand grip to the plate.

[0025]

[Effect of the invention]

 As explained above, according to the grip forming device of the present invention, it is possible to form a textured grip that is moderately airy and has a good texture like a grip grip held by a sushi craftsman. In addition, since sushi rice does not stick, cleaning up is easy.
