  However, the conventional rice ball case has a disadvantage that the user must separately prepare an elastic ring string such as a rubber band as a connecting member for connecting the upper container body and the lower container body. Further, when the rice ball case is stored in a cupboard or the like when not in use or carried, there is a disadvantage that a plurality of rice ball cases are separated and difficult to handle.

  The present invention has been devised in view of such problems of the prior art, and can easily connect the first container and the second container that define the rice ball storage chamber, and can be used when not in use. It is an object to provide a rice ball case group that can be easily stored and carried.

  A first device devised to solve the above problems is a rice ball case group composed of a plurality of rice ball cases each having a first container and a second container that together with the first container defines a rice ball storage chamber. The first container has a first opening edge that defines the opening and a plurality of locking pieces extending from the first opening edge, and the second container has the opening. And a second opening edge that fits into the first opening edge and a plurality of locking claws that respectively lock the locking pieces, and the plurality of rice ball cases have a size relative to each other. It is different, and it is set as the structure which can accommodate other rice ball cases in the largest rice ball case in a nested form.

  Further, as a second device, the first opening edge has a triangular shape, and the locking piece is one on each of two sides of the three sides defining the triangular shape at the first opening edge. In addition to being provided, the two locking pieces may be arranged so as to be biased to one side from the respective midpoints on the two sides in a direction in which they are separated from each other.

  Further, as a third invention, the plurality of rice ball cases are configured such that the calories of rice that can be stored in the rice ball storage chamber are displayed on at least one of the first container and the second container. Can do.

  According to the first device, the first container and the second container defining the rice ball storage chamber can be easily connected by the locking pieces and the locking claws, and the other rice balls in the largest rice ball case. By storing the case in a compact manner in a nested manner, it can be easily stored and carried in a cupboard when not in use. Moreover, according to the said 2nd invention, it becomes possible to connect a 1st container and a 2nd container stably by simple structure. In addition, according to the third aspect, the user can select a rice ball case of an appropriate size according to the calorie display.

It is (A) bottom view, (B) front view, (C) side view, and (D) top view of the upper container of the rice ball case according to the embodiment. It is (A) bottom view, (B) front view, (C) side view, and (D) top view of the lower container of the rice ball case according to the embodiment. It is sectional drawing which shows the assembly state of the rice ball case which concerns on embodiment. It is a figure which shows an example of the calorie display in the rice ball case which concerns on embodiment. It is a top view of the rice ball case group which concerns on embodiment.

  Hereinafter, a rice ball case group including a plurality of rice ball cases according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 2, the rice ball case 1 individually accommodates a so-called triangular rice ball (not shown), and forms an upper container 2 that forms an upper half thereof and a lower half thereof. And a lower container 3 that defines a rice ball storage chamber V (see FIG. 3) in which a rice ball is stored together with the upper container 2. The upper container 2 and the lower container 3 have a bottomed triangular tube shape that is halved at a substantially middle height of the rice ball case.

  As shown in FIG. 1, the upper container 2 has an opening edge 12 that defines a substantially triangular opening 11 formed at the bottom thereof. Further, the upper container 2 includes two locking pieces 13 and 13 that extend outward from the opening edge 12 in a direction perpendicular to the opening edge 12.

  The locking pieces 13 and 13 are rotatably provided on the bottom side (that is, the lower container 3 side in the connected state shown in FIG. 3) with the connecting portion 13a with the opening edge 12 as a fulcrum. Further, the locking pieces 13 and 13 are provided one on each of the two sides 12a and 12b among the three sides 12a to 12c (see FIG. 1A) that define the opening edge 12.

  As shown in FIG. 2, the lower container 3 has an opening edge 22 that is formed in an upper portion thereof and defines an opening 21 having substantially the same shape as the opening 11 of the upper container 2. Further, the lower container 3 has locking claws 23, 23 projecting from the side surfaces at positions corresponding to the locking pieces 13, 13 of the upper container 2. When the upper container 2 and the lower container 3 are connected, the locking pieces 13, 13 are rotated so that the locking claws 23, 23 are locked to the locking pieces 13, 13. Inserted into the hole 15, the peripheral edge of the locking hole 15 is locked. Thereby, the upper side container 2 and the lower side container 3 can be connected simply and stably.

  The two locking pieces 13 and 13 (the same applies to the locking claws 23 and 23) are arranged so as to be biased to one side from the respective middle points Ca and Cb on the two sides 12a and 12b in a direction away from each other. ing. In particular, the locking pieces 13 and 13 may be arranged so that the center position thereof is 1/3 from one end side of each side 12a and 12b. It becomes possible to more stably connect the upper container 2 and the lower container 3 using only two sets of engaging portions composed of 23 and 23.

  Here, as shown in FIG. 3, the opening edge 12 of the upper container 2 is thinned by notching the inner peripheral surface side by the thickness of the opening edge 22 of the lower container 3. On the other hand, the opening edge 22 of the lower container 3 is thinned by notching the outer peripheral surface side by the thickness of the opening edge 12 of the upper container 2. With such a configuration, the opening edge 22 of the lower container 3 can be fitted inside the opening edge 22 of the upper container 2.

  Moreover, as shown in FIG. 4, it has the display part 25 of the calorie (here 320kcal) of the rice (thing except the ingredient with white rice) which can be accommodated in the rice ball storage chamber V in the bottom face of the lower container 3. . Thereby, the user can know the standard of the calories of the rice balls contained in the rice ball case 1.

  As shown in FIG. 5, the rice ball case group 30 according to the embodiment of the present invention is housed in the above-mentioned rice ball case 1 (hereinafter referred to as a large-sized rice ball case 1) having a maximum size and nested therein. A medium-sized rice ball case 101 and a small-sized rice ball case 201 are possible. With such a configuration of being compactly accommodated in a nested manner, the rice ball case group 30 can be easily stored and carried in a cupboard or the like when not in use.

  The medium-sized rice ball case 101 and the small-sized rice ball case 201 have the same configuration as that of the large-sized rice ball case 1, and the main body (that is, the part that defines the rice ball storage chamber) is a large-sized rice ball case. 1 is substantially similar to the main body. The medium-sized rice ball case 101 and the small-sized rice ball case 201 have locking pieces 13 and 13 and locking claws 23 and 23 having the same shape as the large-sized rice ball case 1, and their arrangement relation is also large. This is the same as the case of the rice ball case 1 of size. Although not shown, the lower container of the medium-sized rice ball case 101 and the small-sized rice ball case 201 have calories (for example, the medium-sized rice ball case 101 is 230 kcal, small as in the large-sized rice ball case 1. The size of the rice ball case 201 is 150 kcal). Thereby, the user can select a rice ball case of an appropriate size according to the calorie display.

  Although this invention was demonstrated in detail based on specific embodiment, these embodiment is an illustration to the last, Comprising: This invention is not limited by these embodiment. For example, the rice ball cases constituting the rice ball case group do not necessarily have a triangular cross-section as in the embodiment, and may have other shapes.
