BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice ball packaging container.

[0002]

2. Description of the Related Art Conventionally, as a packaging form of cooked rice that can be stored for a long period of time, it is generally known that a synthetic resin bag is vacuum packaged or an oxygen absorber is added to hermetically seal the package. Since these packaging containers are bags, they have a defect that they do not have sufficient retention, and it is difficult to retain their shape at room temperature for a long period of time when filled with triangular shaped rice balls. In order to maintain the shape of the rice ball for a long period of time, it is desirable to fill it in a molded container that is excellent in heat retention, but as a conventional rice ball packaging container, fill a plurality of rice balls molded in the rice ball storage part of the molded container, A rice ball packaging container that can be packaged while maintaining its shape has not been proposed yet.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a rice ball packaging container that can store a plurality of molded rice balls in a single packaging container having a rice ball filling portion. However, if one rice ball filling section is filled with a plurality of rice balls, the following problems occur. (1) Since a certain degree of draft is required to form a plurality of rice balls into a stackable depth by sheet forming, a slight taper is required. Therefore, a gap may be formed between the rice ball stored in the upper stage and the inner surface of the rice ball filling portion peripheral wall, and the rice ball may move during the distribution stage such as transportation, which may damage the shape of the rice ball. (2) On the other hand, if the rice balls are stacked in multiple stages and the gap between the inner wall surface of the rice ball filling section and the rice ball is made as small as possible so that the rice balls do not move, there is a problem that the rice balls stored in the rice ball filling section become difficult to remove. The present invention provides a rice ball packaging container capable of accommodating a plurality of molded rice balls in a single packaging container having a rice ball filling portion capable of solving the above problems. With the goal.

SUMMARY OF THE INVENTION A rice ball packaging container of the present invention comprises a top wall and a plurality of rice ball filling portions formed so as to hang down from the top wall and accommodate a plurality of rice balls in a stack. Are formed by integral molding, and the rice ball filling part
On the inner surface of the surrounding wall, the rice balls that are stacked in multiple layers are placed vertically
Formed with multiple protrusions that are aligned with each other and hold so that they do not move
The above problem (1) has been solved by the means characterized in that Further, the above problem (2) is solved by forming a finger insertion concave portion in the inner surface of the peripheral wall of the rice ball filling portion, the finger insertion concave portion having an axially extending size from the top wall.

[0005]

[Function] A plurality of protrusions formed on the inner surface of the peripheral wall of the rice ball filling section contacts the outer surface of the rice balls stacked in a plurality of stages on the rice ball filling section and holds the rice balls in a vertical state so as not to move. At the same time, it also plays a role of reinforcing the rice ball filling portion. Also, by inserting a finger into the recessed portion of the rice ball filling portion, the finger can also touch the rice balls located in the lower stage, making it easy to take out even in a multi-tiered stack. According to the rice ball packaging container of the present invention, a single container can be filled with a plurality of rice balls as it is, so that the rice ball can be taken out of the container as needed for business or household use. By heating in a microwave oven, you can easily obtain rice balls just like freshly cooked rice.

Embodiments of the present invention will be described below with reference to the drawings. The drawings show an embodiment of a rice ball packaging container according to the present invention. In the figure, reference numeral 1 is a rice ball packaging container formed of a material having a high gas barrier property, such as a single plastic or a composite plastic, or a plastic and aluminum foil laminated composite material. The rice ball packaging container is formed into a flat rectangular top wall 2 and a triangular rice ball shape that can hang down from the top wall 2 and store a plurality of rice balls (three in this embodiment) in a stack. The two rice ball filling portions 3 are integrally formed.

The rice ball filling section 3 has a slight taper because a certain degree of draft is required in order to mold a plurality of rice balls into a stackable shape by sheet molding. . Therefore, a gap is created between the rice balls stored in the upper row and the inner surface of the rice ball filling part peripheral wall,
There is a risk that the rice ball will move loose. In order to prevent this, in this embodiment, a plurality of (three) protrusions 5 are formed in the axial direction on the inner surface of the rice ball filling portion peripheral wall. The protrusion 5
Is formed so that there is a slight gap with the rice ball so that it does not get in the way when storing the rice ball in the container, but if you store it at room temperature after filling it with warm rice ball, the container will be in a vacuum state, Since the volume of the rice ball is reduced to some extent, the phenomenon is used to make more contact with the rice ball, which prevents the rice ball in the filling part from rustling and prevents the container from shrinking more than necessary. At the same time, it plays the role of reinforcement. The bottom wall 6 of the rice ball filling section 3 is formed in a raised bottom shape. As a result, after the rice ball is filled, the dew condensation that drips along the inner surface of the rice ball filling portion peripheral wall 4 gathers in the groove portion 7 around the upper bottom, and it is possible to prevent the dew condensation water from directly contacting the lower surface of the lower rice ball. Further, by forming the bottom wall 6 in an upper bottom shape, the stability of the container is improved.

As described above, the rice ball filling portion 3 has the tapered rice ball filling portion peripheral wall 4, and the step portion 8 is formed in the upper portion of the peripheral wall. By forming the step portion 8, when empty containers are stacked, the upper and lower containers come into contact with each other at the step portion so that the lower container supports the upper container. This improves the stackability and separability of the container, facilitates the handling when supplying the container to a rice ball filling machine, and improves the mechanical properties. Numeral 10 is a finger insertion recess formed along the peripheral wall of the rice ball filling portion 3 so that the finger can be inserted into the corner portion of the rice ball filling portion 3 so that the peripheral wall of the rice ball filling portion bulges outward from the top wall 2. By inserting a finger into the finger insertion recessed portion 10, even the lower rice ball stored in the rice ball filling portion 3 can be easily taken out. On the other hand, on the top wall 2,
The recessed beads 11 are formed at appropriate intervals to improve the rigidity and reduce the sheet thickness, and the cost is reduced. Reference numeral 12 is a seal ring formed to improve heat sealability when heat-sealing a cover film (not shown). The seal ring 12 protrudes upward in the vicinity of the peripheral portion of the top wall and is formed into a convex strip in a square closed loop shape. Has been done.

The rice ball packaging container of this embodiment is constructed as described above, and can store three preformed rice balls 13 in each rice ball filling section 3, and a proper gas barrier property after storage. By heat-sealing the cover film on the upper surface of the top wall, a rice ball package in which six rice balls are hermetically packaged can be obtained.

[0010]

[Effects of the Invention] The rice ball packaging container of the present invention is constructed as described above and has the following special effects. According to the rice ball container of the present invention, a plurality of rice balls can be filled and stored in a single container with good shape retention property. Therefore, by heating in a microwave oven or the like as needed for business use or household use, You can easily get rice balls just like you cooked rice. Since the rice ball filling section has multiple protrusions on the peripheral wall, it is possible to prevent the rice balls stacked in multiple stages in the filling section from moving vertically inside and impairing the shape of the rice ball. Never. Since the finger insertion recess is formed in the rice ball filling portion, even rice balls stacked in multiple stages can be easily taken out.
