Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for containing liquid-containing fermentable foods such as pickles.

Liquid-containing fermentable foods such as pickles are desired to be put on a packaging container so that the taste is not deteriorated even during physical distribution such as transportation. However, for packaging containers, it is not easy to make good use of fermented food containing liquid such as pickles.

[0003]

2. Description of the Related Art Incidentally, a packaging container for fermentable foods containing liquids such as pickles has not been developed so far so that the contents can be effectively tasted.

A packaging container for containing this type of food is required to have hermeticity in order to prevent the surroundings from being contaminated by liquid leakage. Thus, the internal pressure of the container fluctuates depending on the progress of fermentation of the contained food, etc. In order for the content food to be successful, the internal pressure fluctuation of the container must be changed correspondingly. Conventionally, this point has not been solved.

[0005]

The problem to be solved is the above-mentioned unsolved problem in the prior art.

[0006]

To solve the above problems, the present invention has the following configuration.

[0007] Each of them is a tray-shaped container body made of a plastic molded product, a tray-shaped inner lid that is vertically fitted in the container body under taper fitting due to surface contact of the peripheral wall, and a vertical direction in the container body. A liquid-containing fermentable food packaging container comprising a lid adapted to be held while maintaining a certain relational position, and a portion of the container body that is pushed down by the lid is formed in the inner lid.

[0008]

The invention will now be described with reference to the accompanying drawings which illustrate an embodiment of the invention. 1 is a partially longitudinal front view according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of a fitting portion of a container body and an inner lid and a lid closing portion of the container of the present invention of FIG.

1 is a container body, 2 is an inner lid, 3 is a lid,
Each is made of plastic molding. The container body 1 has a tray shape. The inner lid 2 has a tray shape that is fitted in the container body 1 so as to be vertically movable under a taper fitting due to surface contact of the peripheral wall 21 thereof. In the illustrated case, the inner lid peripheral wall 21 has a two-step taper in which a region above the middle of the peripheral wall is slightly steeper than a region below the middle wall. The lid 3 is adapted to be placed on the container body 1 in the up-down direction while maintaining a certain relational position. The holding structure of the lid 3 with respect to the container body 1 at the fixed relational position is provided with a protrusion 4 formed in a required portion of the container body 1 and extending in the circumferential direction of the container body 1, and a lid engaging with the protrusion 4. The groove 5 formed in the required portion of 3 can be advantageously applied. The inner lid 2 is provided with a portion 6, for example, a flange, which is pushed down by the lid 3 mounted on the container body 1.

As is apparent from the above, when the inner lid 2 is fitted in the container body 1 and the lid 3 is mounted on the container body 1 so as to occupy a predetermined vertical relation position, the container body 1, the inner lid 2 and The inner lid 2 is pressed down by the lid 3 under the elasticity of the plastic molding of the lid 3, and the fermented food (not shown) containing the pickled liquid in the container is added by the inner lid 2.

The above-mentioned reduction is carried out in such a manner that the peripheral wall 21 of the inner lid 2 comes into surface contact with the inner surface of the body of the container body 1, and the surface contact is made under taper fitting. Also, the inner lid 2 is the container body 1.
It is possible to move up and down.

Therefore, when the pressure in the container is low, the inner lid 2 is pushed down more strongly by the lid 3 under the plastic elasticity. If the internal pressure of the container is high, the effect of pushing down the inner lid 2 is weaker than the above due to the internal pressure and the resistance due to the taper fitting.

That is, according to the present invention, the fermented food containing the liquid such as pickles in the container can be used by the inner lid 2 in a manner that the diaper follows the high and low of the internal pressure of the container in a weak and strong manner. It is advantageous in such a preferred embodiment that the container body 1 and the inner lid 2 are tray-shaped, and the container formed by the container body and the inner lid expands and contracts under the elasticity of plastic depending on the internal pressure. Is also a factor.

[0014]

As described above, according to the present invention, the fermented food containing the liquid such as pickles in the container can be effectively treated in response to the fluctuation of the internal pressure of the packaging container.
