Description

[Detailed Description of the Invention] The present invention relates to an airtight container made of synthetic resin that can be used for any purpose such as a vegetable container.

This type of container has a main body sealed with a backing and a lid tightly tightened with a sealing member to prevent the liquid from leaking out.
As seen in Yotsusae's invention, there are also cases where the body and lid are made of plastic injection molded products.

However, in these cases as well, the parts that tighten the lid to the main body for sealing are made of metal, which requires metal processing for manufacturing, which is not desirable in terms of parts management.Furthermore, the metal fittings, which are essential for the product, stand out and are often hanging around. There were several problems, such as being difficult to see and handle, making the container as a whole seem unbalanced.

The purpose of this invention is to solve the above-mentioned problems by forming at least the sealing piece and the container body from a synthetic resin material, so that the sealing action is reliable and the lid is pivotally attached to the container body so that it can be used without being separated. To provide an airtight container which is easy to control, has a uniform structure and design, does not allow sealing members to dangle, has a uniform structure and design, is easy to control, and is excellent in mass production.

The above purpose is particularly to form the sealing piece 3 and the container body 1 with synthetic resin material, and to seal the distance from the center of the shaft portion 5 provided on the sealing piece 3 to the pivoting end of the sealing piece 3 in contact with the container body 1. A structure in which the rotational position of the piece 3 is varied makes it distantly related.

That is, the distance of the sealing piece 3 is a short distance a (Fig. 4, Fig. 8).
At this time, the lid is removed and hangs down along both sides of the container body 1, and when the sealing piece 3 is rotated upward to close the lid from this state, it must pass through the long distance.

Therefore, when the lid is removed, the sealing pieces 3 are restricted to positions on both sides of the main body 1, so they do not wander around, and the operation of the sealing pieces 3 before and after rotation also gives a sense of moderation.

In order for the sealing piece 3 to be able to rotate between the different distances a and b, it is necessary that the sealing piece 3 or the container body 1 be elastically deformed to such an extent that they are molded from a synthetic resin material.

The present invention will be explained below with reference to examples.

In the illustrated embodiment, a box-shaped container body 1, a lid 2 attached thereto, and at least two sealing pieces 3 for fixing the lid 2 to the container 1 are all made of synthetic resin.

Notches 4, 4 are provided at both left and right ends of each sealing piece 3 from below, respectively, and a shaft portion 5 for rotation is provided in each notch 4.

Reference numerals 6 and 6 denote retaining pieces that engage with each shaft portion 5, and a pair of retaining pieces 6, 6 are provided protrudingly provided on the outer side of the facing surface of the container body 1.

In addition, the lid 2 has a fitting groove 9 on the back side for a backing 8 that tightly fits the wide upper edge 7 of the container body 1.

Furthermore, a locking protrusion 11 that fits into the slot 10 provided in the sealing piece 3
are provided on parallel sides of the lid 2 so as to protrude outward.

The engagement piece 6 may be made of metal.

The engaging piece 6 shown in FIG. 5 is formed into a hook shape and is hooked onto the shaft 5, and in the examples shown in FIGS. 6 and 7, one end of the shaft 5 is released. The shaft portion 5 is fitted into the hole 6' of the engagement piece 6.

Furthermore, in order to achieve the purpose of preventing the sealing piece 3 from shaking when the lid is removed, the sealing piece 3 is in contact with the container body 1 from the center of the shaft portion 5 or 5a of the sealing piece 3, as shown in FIGS. 4 and 8.
By increasing the distance b relative to the distance a to the rotation end of the body 1, the shaft portion 5 once fitted into the main body 1 or its hole 6'' can be rotated from the position indicated by the solid line to the positions indicated by the chain lines X and Y in the same figure due to the difference in distance.
Alternatively, press 5a so that it sticks tightly to the main body at positions X and Y so that it is firmly fixed without wobbling.

At position X, the sealing piece 3 serves as a handle.

Furthermore, when the lid is in the lid tightening position shown by the solid line, it can be slid by the sealing piece 3 as a push-type shelf case.

As shown in FIGS. 4 and 8, the locking protrusion 11 has an upward bulge 11' at its tip, and the bulge 11' is formed on the upper surface of the slot 10 provided in the sealing piece 3. The locking action is ensured by providing a stepped portion 11' with which the locking mechanism 11' is engaged.

The groove hole 10 and the locking protrusion 11 can also be provided in two or three strips.

Since the present invention is based on the structure described above, the lid 2 is firmly attached to the container body 1 by the synthetic resin sealing piece 3 to achieve a sufficient sealing effect, and one sealing piece 3 is attached to the lid 2. When the lid 2 is removed from the container body 1, the lid 2 can be opened using the shaft 5 of the other sealing piece as a fulcrum, and the lid 2 can be used without being separated from the container body 1. The distance from the center of the shaft portion 5 to the rotating end in contact with the container body 1 changes due to the rotation of the sealing piece 3, which becomes the shortest distance when the sealing piece 3 is out of position. Since they fit tightly together, there is no looseness, making the container extremely easy to use.Furthermore, since no or only a small amount of metal is used for the sealing piece 3, unlike conventional containers, it is easy to unify the structure and design of the entire container. Since parts are easy to manage, mass production is advantageous.
