As shown in FIG. 6C, when the two trays 10 are stacked one on top of the other, one ridge 15 fits exactly into the other engaging groove 16 as shown in FIG. .
That is, the inside of the trap ball tray 10 is shielded from the outside air by the close contact between the ridge 15 and the engagement concave groove 16. Also,
If a large number of ball trays 10 are superposed in the same direction, the food pockets 12, 12 also overlap as in the prior art, and as shown in FIG. The layers are overlapped with a gap left therebetween, and the thickness in the height direction is maintained as before.

Next, the ridges 15 of the ball trays 10 and 10 are formed.
The function of the engagement groove 16 will be described. First, when the manufactured ball trays 10 and 10 are shipped, many of them are stacked in the same direction. At this time, the ridges 15 and the engagement grooves 16 engage with the irregularities formed on the back surface of the other ball trays 10, respectively, so that the whole can be packaged in a small size (FIG. 6B). reference).

When using the shading ball tray 10, 1
Ingredients are put into individual shading ball trays 10, and other shading ball trays 10 are placed facing each other from above. Then 2
The main bodies 11 and 11 of the individual ball trays 10 and 10 are overlapped with each other in a state where the ridges 15 and the engagement grooves 16 are unevenly engaged with each other (see FIG. 6C). Therefore, the ball tray 1
0, 10 food pockets 12, 12 are isolated from the outside,
The drying speed of the ingredients stored therein becomes slow.

The shading ball trays 10 and 10 are formed by engaging the ridges 15 and the engaging grooves 16 in an uneven manner.

The ridge 15 and the engagement groove 16 of the first embodiment are formed in an L-shape when viewed from the front, whereas the ridge 15 and the engagement groove 16 of the second embodiment are formed in a U-shape when viewed from the front. Have been.

FIG. 7A is a perspective view of the ball tray 10, and FIG. 7B is a front view of the ball tray 10. FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 7 (a), on the periphery of the main body 11, an elongated ridge 15 bulging toward one side and an engaging recess bulging toward the other side are provided. Groove 1
6 are provided. These ridges 15 and engagement grooves 16
Is formed in a trapezoidal convex and concave shape in a cross-sectional view, as in the first embodiment, and is configured to be able to engage with the concave and convex with each other.

The protrusion 15 and the engagement groove 16 are shown in FIG.
As shown in the figure, each is formed in a U-shape in a front view, and is disposed at a position substantially symmetrical with respect to an imaginary line A passing substantially at the center of the main body 11 along the longitudinal direction of the main body 11. . Therefore, by covering the main body 11 so as to face the other main body 11, the ridge 15 (the engagement groove 16) can be made to engage with the engagement groove 16 (the protrusion 15). Therefore, by such a concave-convex engagement, foods such as shading balls stored between the main bodies 11 can be shielded from the outside air, and the drying of the foods can be prevented.

Since the ridge 15 and the engaging groove 16 are formed in the peripheral portion of the main body 11 so as to include four corners 11a and bulge in a substantially trapezoidal shape in cross section, the main body 11
It also has the function of strengthening (reinforcing) the rigidity of the peripheral edge of. Accordingly, the main body 11 can be stably maintained in a flat shape without deforming the peripheral portion, and therefore, when another main body 11 is covered face to face, the space between the opposing surfaces of the peripheral portion can be maintained. That is, it is possible to prevent a gap from being generated.

Next, a third embodiment will be described with reference to FIGS. In the first embodiment, at least one ridge 15 and at least one engaging groove 16 are provided on the periphery of the main body 11, and the other main body 11 is superposed on the main body 11 so as to face each other. And so on. On the other hand, in the third embodiment, the main body 11 in which one of the ridge 25 or the engagement groove 26 is disposed continuously over the entire peripheral portion, and the engagement groove 26 or the protrusion 2
5 is provided with a lid 21 disposed continuously over the entire periphery of the peripheral portion, and the lid 21 is placed on the main body 11 so as to face the main body 11 so as to cover foods such as shaving balls. It is configured.

FIG. 8 is a perspective view of the main body 11, and FIG. 9 is a perspective view of the lid 21. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 8, a ridge 25 is formed on the periphery of the main body 11 so as to bulge toward one side, and on the periphery of the lid 21, as shown in FIG. The engagement groove 26 is formed so as to bulge toward the other side, that is, toward the opposite direction to the ridge 25 of the main body 11. As in the first embodiment, the ridge 25 and the engaging groove 26 are formed in a trapezoidal convex and concave shape in cross section, and are configured to be able to engage with each other.

Here, the difference between the configuration of the main body 11 and the lid 21 is that the main body 11 is provided with a ridge 25, whereas the lid 21 is replaced with the ridge 25. This is the point that the concave groove 26 is provided, and the other portions are configured in the same shape. That is, the lid 21 is
1 is formed in a plate-like body having substantially the same size as the outer shape of the main body 11, and on one side thereof, the same number of food pockets 12 as the food pockets 12 provided in the main body 11 are arranged in substantially the same arrangement. I have.

As shown in FIG. 8, the ridge 25 is
As shown in FIG. 9, the engagement concave groove 26 is formed so as to bulge in a continuous state along the entire periphery of the cover 21 and along the periphery of the cover 21. Is formed so as to bulge in a continuous state over the entire periphery of the peripheral portion. Therefore, when the lid 21 is covered on the main body 11 to face each other, the engaging groove 26 of the lid 21 engages with the ridge 25 of the main body 11 unevenly, and the peripheral edges of the main body 11 and the lid 21 are connected. It is connected without interruption all around. Therefore, foods such as shading balls can be encapsulated between the main body 11 and the lid 21 in a substantially sealed state, and the food materials such as shading balls can be almost completely shielded from the outside air. . Therefore, it is possible to prevent foodstuffs such as shading balls housed by the inflow of outside air from drying out or impairing the internal hygiene.

The periphery of the main body 11 and the lid 21 provided with the ridges 25 and the engagement concave grooves 26 are the same as in the first embodiment.
The rigidity is reinforced (reinforced), and the shape can be stably held in a flat shape without being deformed. Therefore, when the lid 21 is covered by the main body 11, it is possible to prevent a gap from being formed between the opposing surfaces of the peripheral portion.

In the case where the main body 11 or the lid 21 has a portion where the rigidity is not enhanced at the peripheral portion, that is, a portion where the ridge 25 or the engaging groove 26 is not provided, When transporting foodstuffs such as the above, the deformation concentrates on the non-arranged portions, and the main body 11 and the lid 21 are largely bent. As a result, there is a possibility that foods such as shaving balls may fall off to the outside, or deformed portions may be damaged. However, the main body 11 and the lid 21 in the present embodiment are provided with the ridges 25 and the engagement grooves 26 without interruption over the entire periphery thereof, so that the deformation is concentrated at one place. It can be prevented and transported safely.

Next, the rib 13 provided on the ball tray 10 will be described. The ribs 13 are for increasing the rigidity (strength) of the ball tray 10 and are provided between the food pockets 12 of the main body 11 or the lid 21.

Here, since the shaping ball tray 10 is formed in a thin box-shaped body with one side opened and made of a synthetic resin material such as styrene foam, it has sufficient rigidity (strength). It is hard to say that there is. Therefore, during transportation, the ball tray 10 may be bent by the weight of the stored items such as the ball, and the stored items may fall out of the ball tray 10. However, when the thickness of the shading ball tray 10 is increased or a special reinforcing member is provided, insufficient rigidity of the shading ball tray 10 is resolved. This leads to a problem that the installation space of the twelve is reduced, and the number of foodstuffs such as shaved balls is reduced. In the present invention, the rib 13 is provided between the food pockets 12 to solve the above-mentioned problem.

The rib 13 has a common configuration in all of the first to third embodiments. That is, the subject 11 in the first to third embodiments.
In addition, the configuration of the rib 13 is common to the lid 12 in the third embodiment. Therefore, the configuration of the rib 13 will be described with reference to FIGS. 1 to 4 using the first embodiment as a representative example.

As shown in FIG. 1, a plurality of food pockets 12 each having a substantially rectangular shape in a front view are provided on one side of the flat main body 11 so as to protrude, and the remaining portion is left as a flange portion 19. As shown in FIG. 2, the food pockets 12 are arranged on one side of the main body 11 in a state of being arranged in a vertical and horizontal grid, so that the flange portions 19 are formed in a vertical and horizontal lattice shape between the food pockets 12. ing.

The number of the food pockets 12 is five in the vertical direction (vertical direction in FIG. 2) and ten in the horizontal direction (horizontal direction in FIG. 2).

The vertical ribs 20 are, as shown in FIG.
The food pocket 12 is formed so as to bulge in the same direction as the food pocket 12, and the bulge reinforces the rigidity (strength) of the main body 11 in the vertical direction. In addition, this vertical rib 20
Of the food pocket 12 (vertical depth in FIG. 3).
Is about 2/3 to about 3/4 with respect to the bulging depth. In addition, the width of the vertical rib 20 (the dimension in the left-right direction in FIG. 3) is set to be approximately １ ／ of the short side dimension of the food pocket 12 at the widest point.

On the other hand, as shown in FIG. 2, the finger recess 14 is located at a position crossing a substantially central portion in the longitudinal direction of the food pocket 12 in a row of the food pockets 12 aligned in the lateral direction (left and right in FIG. 2). Is provided. This finger depression 14
All food pockets 1 aligned horizontally (Figure 2 left and right)
2 are formed, and the finger depressions 14 are formed between all the food pockets 12 (flange portions 19) in the row of the food pockets 12 where the finger pockets 14 are formed.

As shown in FIGS. 3 and 4, the finger dent 14 is formed so as to bulge in the same direction as the food pocket 12, and the bulge causes the main body 11 to swell.

Further, since the vertical ribs 13 are formed in three rows of the food pockets 12 aligned in the vertical direction of the main body 11, the arrangement of the vertical ribs 20 in the oblique direction of the main body 11 is discontinuous. can do. Accordingly, the rigidity of the main body 11 in the oblique direction can be improved, and as a result, the bending of the shaping ball tray 10 (main body 11) in the oblique direction during transportation is suppressed, and the shark contained in the food pocket 12 is suppressed. It is possible to prevent foods such as balls from falling out of the tray 10.

The finger recess 14 is provided in the food pocket 12.
Is formed in the flange portion 19 between all the food pockets 12 at a position crossing substantially the center in the longitudinal direction, so that the discontinuity of the vertical ribs 20 is maintained and the main body 11 is prevented from bending obliquely. At the same time, it is possible to easily pick up and take out ingredients such as shading balls stored in the food pocket 12.

As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. That is easy to guess.

For example, in each of the above-described embodiments, a description has been given of a rice ball for nigiri sushi as an object to be stored in the food pocket 12 of the rice ball tray 10 of the present invention. It is needless to say that the application of the present invention is not limited to nigiri sushi, and the present invention can be applied to various food materials such as mochi, dumpling, sh シ ュ ー mai, gyoza, and the use thereof is naturally included in the technical scope of the present invention. .

According to the present invention, if two trays are stacked facing each other,
Since the ridges and the engagement grooves provided along the periphery of the ridges and protrusions engage with each other to suppress the free flow of air, it is possible to prevent the drying of the balls stored in the ball tray. This has the effect. In addition, since the two superimposed ball trays are joined by the ridges and the engagement grooves being unevenly engaged with each other, they can be held in a lightly joined state without using rubber bands. This has the effect of facilitating the work of packing the balls into the ball tray. Further, since the peripheral edge of the plate-shaped main body of the trap tray is reinforced by the ridges and the engagement grooves, there is an effect that deformation and breakage during transportation are reduced and handling is facilitated.

According to the second embodiment of the present invention, in addition to the effects of the first embodiment, the same direction can be obtained even when the trays are stacked face to face. Even when they are stacked, the phases of the balls are matched, so that there is an effect that the work of packing the balls is easy.

According to the fourth aspect of the present invention,
When the two ball trays (the main body and the lid) face each other and overlap each other, the ridges provided along their peripheral edges and the engaging grooves engage with each other. In this case, since the ridges and the engagement concave grooves are provided continuously along the entire periphery along the peripheral portion, the free flow of air can be suppressed over the entire peripheral portion, and as a result, In addition, there is an effect that drying of the balls stored in the ball tray can be further prevented.

Therefore, when each ridge and the engaging concave groove engage with the concave and convex, the concave and convex portion also engage, and each ridge and the engaging concave groove are positioned not only in the width direction but also in the longitudinal direction. This has the effect of increasing the overall rigidity when stacking the ball trays face-to-face. Also, by the engagement of the concave and convex portions of the ridge and the engagement concave groove,
Since the frictional resistance can be increased by that amount, there is an effect that the state in which the ridge and the engagement groove are joined can be more firmly held.

[0071] According to the present invention, there is provided a shading ball tray.
In addition to the effect of the shading ball tray according to any one of claims 1 to 5, since the main body and the lid have vertical and horizontal reinforcing ribs formed on the flange portion between the food pockets,
There is an effect that the rigidity of the main body and the lid can be improved. Further, since the vertical reinforcing ribs are formed in a row in several rows of the food pocket row, the arrangement of the vertical reinforcing ribs in the oblique direction of the main body and the lid can be discontinuous. Therefore, there is an effect that the rigidity of the main body and the lid in the oblique direction can be improved. Therefore,
It is possible to suppress slanting bending of the main body and the lid during transportation, and prevent foodstuffs such as shading balls stored in the food pocket from falling out of the main body and the lid.

According to the seventh aspect of the present invention,
In addition to the effect of the ball tray according to claim 6, since the horizontal reinforcing ribs are formed on the flanges between all the food pockets at a position crossing substantially the center in the longitudinal direction of the food pocket, the vertical reinforcing ribs are formed vertically. There is an effect that it is possible to easily pinch and take out food materials such as shading balls stored in food pockets while maintaining the discontinuity of the reinforcing ribs and suppressing the bending of the main body and the lid.

According to the present invention, there is provided a ball tray.
In addition to the effects achieved by the paddle tray according to the sixth or seventh aspect, the projections and recesses of the engagement grooves are projected or recessed at positions corresponding to the flanges between the food pockets. Therefore, by using the space effectively, it is possible to secure a space for disposing the food pocket 12,
As a result, there is an effect that it is possible to prevent the amount of foodstuffs such as shading balls from being reduced or to prevent the shading ball tray from being enlarged.
