DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure for a filling container for offering rice cakes.

[0002]

2. Description of the Related Art A transparent or semi-transparent thermoplastic synthetic resin is blown into a filling container in which an upper stage small container and a lower stage large container are concentric circles in plan view and are blow-molded in a communicating state inside. All rice cakes are poured and sealed, then heat sterilized and cooled to solidify, and then sold as kagami rice cakes or other offering rice cakes packed in the container.
Regarding such a filling container for offering rice cakes, the present inventor has already proposed Japanese Patent Publication No. 59-35579 and Japanese Utility Model Publication No. 58-11.
No. 6573, No. 62-13495, No. 63-63
No. 23342, Jikken 1-20302, etc. were proposed.

In these known means, when sealing the rice cake pouring opening formed on the bottom surface of the filling container, a seal cover (seal piece) which is thinner than the wall thickness of the container itself is used. This is welded (heat-sealed) to the bottom surface of the filling container by a hot platen or the like.

Regarding the purpose of adopting the thin seal cover, as described in Japanese Utility Model Publication 1-20302, when the seal cover is thicker than the container itself, it is poured into the container. When the volume of the rice cake shrinks due to subsequent cooling action, or when the air enclosed in the rice cake and its container expands due to the subsequent sterilization boil action, the shrinkage and expansion are sealed. Cannot be reliably absorbed and compensated by the container, and the thin-walled part of the container itself becomes a weak point, so that the container partially collapses or expands, creating an appearance that is important as a commercial value for this kind of rice cake. This is to prevent this as it will result in inhibition.

[0005]

However, as described above, the structure in which the thickness of the seal cover is simply made thinner than that of the filling container itself has the following problems.

That is, even if the seal cover is provisionally thinned, since the container is relatively thicker than the seal cover, in order to instantaneously weld and integrate both of them, it is necessary to melt the container itself. It is necessary to pressurize with a hot plate having a sufficiently high temperature, which causes shrinkage and deformation of the thin seal cover due to overheating, and when printed characters or the like are printed on the seal cover, the printed image line is destroyed.

[0007] As a countermeasure, the above-mentioned Japanese Utility Model Publication No. 62-13
As described in No. 495, "patch cloth" that can withstand the temperature of a hot platen, etc. must be laid and pressure must be applied from above, which is extremely complicated in terms of work and maximizes the effect of mass production. I can't.

[0008] In this respect, the Japanese Utility Model Publication No. 62-13495 also states, "In addition, the seal piece is shown in FIG. 7 so that it can be easily heat-sealed to the bottom surface of a plastic-made container (a) such as a plastic. The fused surface is polypropylene (e ') as shown
However, it is better to form the outer surface with two layers so as to make it a vinyl box (e ''). "

However, in the case of the two layers, polypropylene, which comes into direct contact with the bottom surface of the container, has a higher heat resistance (melting temperature) than the vinyl chloride forming the outer surface, and the vinyl chloride has the above-mentioned contact. Since it cannot function as a cloth, it still causes the above-mentioned problems.

On the other hand, in Japanese Utility Model Publication No. 56-24664,
Odor in a single round rice cake-shaped container vacuum-formed from propylene
And put the seal cover (cover material) (13) on the bottom of the container.

However, the laminated sheet (1
5) is the rigidity to withstand heat sterilization of rice cake,
It is for preventing the deformation of the rim (12).

The laminated sheet (1
It is difficult to apply 5) as it is. Cover the latter
So, compared to the former, the volume of rice cake poured into the container is about
It is twice as large as the shrinkage and subsequent sterilization
The swelling that accompanies the action of the
The thinnest part that is the weak point collapses or expands
The seal cover will

is there.

Further, polypropylene as in the above-mentioned known device
In the case of a vacuum-formed container (10) from
The lid material (13) that seals the open state is thin because it is in an open state.
If so, the rice cake will easily soften and deform due to heat sterilization
The laminated sheet (1
5) Must be made rigid.

In other words, as the above vacuum formed article
Since the bottom surface of the container (10) is completely open,
Simply peeling or cutting the lid material (13)
The rice cake can be taken out from the container (10)
It can be said that there is no need to cut and disassemble yourself.

However, when the large and small containers are stacked,
-In the molded kagami-mochi type container, the bottom of the large container
Because the rice cake pouring opening that opens is small, a seal for sealing it
Take off the rice cake just by peeling or cutting the cover
Is impossible, and the container itself must be cut with a blade.
Ri must be dismantled, guide to consumers this thing
There are also technical reasons and needs.
