DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling container for offering rice cakes and a method for producing the same.

[0002]

2. Description of the Related Art Freshly brewed rice cake is poured into a transparent synthetic resin filling container in which an upper small container and a lower large container are concentric circular in plan view and are integrally molded in a communicating state inside. It is filled, then heat sterilized and solidified by cooling, and sold as kagami mochi or other offering rice cake in a hermetically sealed state in the container. Submitted by JP-A-5
No. 178368 is known.

Then, in this, the large and small containers (12) (1
A circular rice cake pouring opening (17) having a diameter smaller than the diameter (s1) of the concave circumferential groove portion (13) which forms the boundary of 1) is opened at the center of the bottom surface of the lower large container (12). , A seal cover (3) for sealing the rice cake pouring opening (17)
The wall thickness of 4) is made even thinner than the thinnest part of the container itself.

[0004]

However, even if the seal cover (34) is thinned in comparison with the container itself, it is soaked in hot water for sterilization after sealing the rice cake pouring port (17). (Boiling action), the container itself and the rice cake that has once expanded together with the seal cover (34) are subsequently cooled (natural drying) to shrink and solidify. When the cover (34) is suctioned from the inside, it is difficult to completely absorb and compensate the shrinkage amount of the rice cake only by the concave deformation of the seal cover (34).
Not only 4), but also the thinnest central portion of the top surface (North Pole) (a) corresponding to the so-called weak point of the container itself is dented and deformed, and there is no risk of reducing the commercial value.

Even if the lid is covered and the seal cover (34) is made thinner than the thinnest portion of the container itself, the diameter (s2) of the rice cake pouring port (17) sealed by this is small. Because of its size, its seal cover (3
4) The deformation allowable range of itself is limited to a narrow range.

On the contrary, the diameter (d2) of the upper small container (11) in the above container is such that the rice cake pouring port (1)
The size is considerably larger than the diameter (s2) of 7), and the radius of curvature of the top surface is very large, and the shape is close to a horizontal plane.

As a result, if the rice cake is not completely filled in every corner of the container or the rice cake shrinks unexpectedly, the shrinkage amount of the rice cake can be reduced by the seal cover ( If it is not possible to absorb and compensate for even a small amount by only the concave deformation of 34), the central portion (north pole) (a) of the top surface of the container will immediately be depressed like a diaphragm due to the shortage. This is because the suction force that accompanies the shrinkage of rice cake concentrates on the weak point of the container.

Further, in the above-mentioned known container, the concave peripheral groove portion (13) which forms the boundary between the upper small container (11) and the lower large container (12) is shaped so as to stand out as a large step. Nevertheless, the diameter (s2) of the rice cake pouring opening (17) is larger than the diameter (s1) of the concave circumferential groove (13).
The size of the rice cake is so small that it is difficult to fill the rice cake quickly and completely throughout the container.

On the other hand, because of the above problems,
This type synthetic resin filled container Patent Rights 5-178368
When vacuum-formed as the shape shown in FIGS.
By doing so, it is possible to release from the vacuum molding die (1).
In addition, you can get the original realistic beauty of kagami mochi.
Instead, the product value is forced to decline.

Further, in the container as the vacuum formed product,
The diameter of the rice cake pouring mouth (6) is the same as the diameter of the lower large container (4).
Equally, and because its bottom is fully open, seal it
A fairly thick seal cover (8) for
Need to be used.

In this case, if the container is thick,
It becomes difficult to dismantle it, and the container is thin on the contrary.
And the amount of rice cake shrinkage is controlled by the thick seal cover (8).
The center of the top surface of the container itself is dented because it cannot be absorbed or compensated.
It results in deformation.

[0012]
