Description

Container fastening device

The present invention relates to a fastening device for an upper cover and a container, and in particular to a novel technology in which the upper cover is fastened to the container without being loosened.

The conventional container fastening device mainly comprises a container and an upper cover, and the upper cover is fitted to the shoulder of the outer peripheral side of the container by the peripheral block, and the sealing ring attached to the upper cover abuts against the top end of the container.

These prior art techniques have at least the following disadvantages:

1. Since the upper cover is fitted to the shoulder of the outer peripheral side of the container by the peripheral block, the upper cover must have a certain elastic shape variable, so that the peripheral block can be press-fitted to the shoulder of the container, and the upper cover The card block and the shoulder on the outer peripheral side of the container have a margin of spacing, so that the card block of the upper cover can be swung over the shoulder of the container to perform the locking action, and the upper cover block is pressed against the pressing ring. The top end of the container is affected by the restoring force of the upper cover and the sealing ring, which often causes the block of the upper cover to be partially displaced or rotated at a locking angle according to the shoulder of the container, thereby forming a buckle with the container and failing to be completely tightly closed. Phenomenon, when the container is tilted or dumped, the food broth stored in the container will flow out of the gap or ooze out of the container, which will cause the surface of the container to be dirty, while the user is taking the container. If It is not noticed whether the upper cover and the container are tightly combined, and the outer cover is freely taken up, and the container and the upper cover are often separated and dropped, so that the article is scattered or the container is damaged, so that it is not safe in use.

2. When the food or articles are placed in a container for storage, since the combination of the upper cover and the container is not completely tight, it is prone to spoilage or deterioration of the moisture, thereby causing loss in use thereof.

In view of this, the creator has actively worked hard to study, and after many trials and improvements, finally developed a new type of practical effect.

The present invention relates to a container fastening device, which comprises at least: a container having a chamber with an opening facing upward, and a ring top surface defined along a top end of the chamber, and a shoulder portion protruding from the top edge of the container. The bottom surface of the shoulder is concavely disposed with a recessed groove, and the recessed groove forms a first inclined surface opposite to the outer side, so that the groove width of the recessed groove is formed to be downwardly divergent; and a sealing ring whose bottom surface shape matches the top surface of the container ring; And an upper cover, which can cover the top surface of the container ring to close the chamber, and has an inner ring and an outer ring protruding downward to define a groove for the sealing ring to be inserted; the upper cover is opposite to the groove The position is extended with a gusset plate, and a force applying portion is arranged at a free end of the gusset plate, and a card block is arranged between the gusset plate and the force applying portion, and a free end of the card block is provided with a convex rim, and the force applying portion is provided. When the downward movement is performed, the first inclined surface of the clamping block and the recessed groove can be combined and pushed, and the convex flange and the sealing ring are compressed and deformed and clamped on the corresponding groove top and the ring top. The surface enables the upper cover to be tightly assembled on the container by the convex returning edge and the sealing back pressure.

With the overall cooperation, the container of the present invention is completely tightly coupled with the container after being fastened, and the inside of the container can be ensured that the food stored therein does not deteriorate, and the user does not need to pay too much attention. It is easy to handle the container after the lid is closed, so it is very convenient and safe to use.

Preferably, the slot has a second inclined surface opposite to the inner side; when the upper cover is assembled to the container and the biasing portion is pulled upward, the protruding flange can abut the second inclined surface to actuate the upper cover to move upward, thereby sealing The air gap is formed between the ring and the top surface of the container ring, and the upper cover can be easily removed, which is convenient for the user to operate.
