Description

[Detailed Description of the Invention] The present invention relates to an opening/closing lid device for sealing the mouth of a can or bottle.

Conventionally, as shown in FIG. 1, this type of opening/closing lid device includes an opening/closing lid 4 having a plurality of elastic hook pieces 3 formed on the outer periphery for opening and closing an opening 2 of a container 1, and a lid 4 inside the opening/closing lid 4. A dish-shaped packing 5 that can cover only the upper surface of the opening 2 of the container 1, and the opening/closing lid 4.
After attaching the opening 2 to the opening 2 of the container 1, the opening/closing lid 4 cannot be opened unless the outer periphery of the opening/closing lid 4 is covered and the lower part is crimped with a crimping machine to pull and cut the handle 6. The protective band 7 is made of a metal material and prevents this from occurring. Therefore, there were the following drawbacks.

(1) Since it is a dish-shaped packing 5 that can cover only the top surface of the opening 2 of the container 1, the opening/closing lid 4
Packing 5 tends to fall off from the inside, making it difficult to handle.

(2) Due to (1) above, when the opening/closing lid 4 is attached to or removed from the opening 2 of the container 1, liquid such as soy sauce filled in the container tends to adhere to the elastic hook 3 of the opening/closing lid 4. If liquid adheres to the elastic hooking piece 3, rust will develop from that part and the opening/closing lid 4 will become dirty.

(3) Since a protective band made of metal is used, once the opening/closing lid is opened, the device must be used without the protective band, which has the disadvantage that the opening/closing lid may be opened inadvertently.

(4) Since the packing 5 is formed into a dish shape that covers only the upper surface of the opening 2 of the container 1, the contact area between the opening 2 and the packing 5 is small, and the opening 2
If part of the top surface of the container is sunken, it will not be possible to seal it completely.

In view of the above-mentioned drawbacks of the conventional technology, the present invention reliably prevents the packing from falling out from inside the opening/closing lid, and even if there is a dimensional error at the upper end of the opening of the container, the sealing part is brought into close contact with the upper end of the opening/closing lid. To provide an opening/closing lid device which can perform sealing, prevent the opening/closing lid from rusting due to the filling in the container, and can remove a protective band in a state where it can be reused.

As is clear from the above explanation, the present invention has the following effects.

(1) A flange piece is formed on the outer periphery of the packing body that can cover the inner wall surface of the elastic hook piece of the opening/closing lid, so when the packing is attached to the opening/closing lid, the flange piece will lock it inside the opening/closing lid. As a result, the packing does not easily fall off from the opening/closing lid unlike in the conventional case.

(2) Due to (1) above, it is possible to cover almost the entire inner wall surface of the elastic hook of the opening/closing lid, thereby reliably preventing the filling inside the container from adhering to the elastic hook. This can reliably prevent rusting and the opening/closing lid from getting dirty.

(3) The opening/closing lid can be protected with a protective band made of synthetic resin, so even if pressure is applied to the top surface of the opening/closing lid, the protective band can reliably prevent the opening/closing lid from opening, and it can also be prevented from opening again. The protective band can be attached and detached for use.

(4) The tip of the flange piece, which is integrally molded with the seal part, is free instead of being wrapped around and fixed to the tip of the elastic hook piece as in the conventional case, so just insert the packing into the opening/closing lid. The assembly is completed, and the opening/closing lid and packing can be assembled easily and inexpensively.

(5) Since the outer periphery of the flange piece is formed to have a larger diameter than the inner diameter of the open end of the elastic hook piece in the closed state, it can be removed from the inside of the opening/closing lid by simply inserting the packing into the opening/closing lid. can be reliably prevented from falling off.

Furthermore, even if the packing is inserted into the opening/closing lid while the opening/closing lid is in the closed state, the packing is made of synthetic resin material, so the brim portion can also be easily inserted into the opening/closing lid. The opening/closing lid may be opened and the inner diameter of the opening end of the elastic hooking piece may be expanded to store the packing inside, and the opening/closing lid may be closed and the packing may be stored inside the opening/closing lid.
