Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid for a container, which can simplify an initial set for displaying an unopened state of the container and facilitates an opening operation.

[0002]

2. Description of the Related Art An opening indication function (so-called pill proof) which can be attached to a container for storing contents such as liquid beverages and liquid foods to prevent illegal acts such as refilling of contents and guarantee quality. A lid with a cover has been proposed (Japanese Utility Model Registration No. 2530110).

[0003] This is composed of a combination of a lid body and an openable / closable lid attached to the lid body so as to be openable and closable. An elastic engaging piece is provided on the outer periphery of the lid body via a separating portion. It is attached to. Therefore, in this device, the lid body is attached to the container for storing the contents, the opening / closing lid is closed, and both ends of the engaging piece are locked to the finger hooks of the opening / closing lid while bending the engaging piece. By connecting the finger hook to the lid body via the engagement piece, the container can be initially set in an unopened state.
Then, when the opening / closing lid was opened, the separating part was broken, the engaging piece was separated from the lid body and stayed on the finger hook part side of the opening / closing lid, and the container was opened via the breaking mark of the separating part. Can be displayed externally.

[0004] Further, there has been proposed a lid body in which an arrow-shaped engaging piece is attached to the lid body via a separating portion formed in the axial direction (Japanese Utility Model Laid-Open No. 5-82851). When the opening / closing lid is closed, the engaging piece enters the finger hook portion of the opening / closing lid while being elastically deformed, engages with the finger hook portion, and the container can be initially set in an unopened state. When the lid is opened, the separation part is stretched and broken so that the engagement piece is separated from both the lid body and the opening / closing lid, thereby indicating that the container has been opened.

[0005]

In the case of the former of the prior art, the engaging piece must be bent and locked to the finger hook of the opening / closing lid to initially set the container in an unopened state. However, there is a problem that the initial setting work is troublesome. In the case of the latter, the separating portion must be broken by stretching it in the axial direction of the lid body, and the operating force when breaking the separating portion tends to be excessive, and it is difficult to perform the opening operation. There was a problem.

In view of the above-mentioned problems of the prior art, an object of the present invention is to employ an engaging piece having left and right projecting portions, a downward hook portion, and a separating portion projecting in a radial direction of the lid body. Accordingly, it is an object of the present invention to provide a lid of a container that can simplify the initial setting operation, reduce the operating force at the time of opening, and facilitate the opening operation.

[0007]

To achieve the above object, the present invention comprises a lid body attached to a mouth of a container, an opening / closing lid with a finger hook attached to the lid body so as to be openable and closable, An upwardly-facing engaging piece attached to the upper end of the lid main body via a separating portion protruding in the radial direction of the lid main body, the engaging piece includes left and right protruding portions, and respective distal end portions of the protruding portions. And a downward-facing hook portion that folds outward from the outside, and when the opening / closing lid is closed, the projecting portion and the hook portion enter the opening of the finger hook portion,
The gist is that when the opening / closing lid is opened, the hook portion is engaged with the finger hook portion to be plastically deformed and the separating portion is broken.

The finger hook may be formed with an engagement recess that is open at the top and engages with the hook.

The engagement piece may be removable upward through the opening after the breaking of the separation part.

Further, the lid body may be prevented from loosening with respect to the container via a ratchet, and the opening / closing lid may be provided with an inner rib fitted to the annular rib at the upper end of the lid body.

Further, the opening / closing lid may have a stopper surface which comes into contact with the step of the lid main body, and a notch may be formed on the stopper surface corresponding to the finger hook.

[0012]

According to the structure of the present invention, when the opening / closing lid is closed with respect to the lid main body, the hook portion and the projecting portion enter the opening of the finger hooking portion of the opening / closing lid, and the engaging piece engages with the opening. By projecting high upward, the container can be initially set in an unopened state. In addition, when the opening / closing lid is opened, the hook portion engages with the finger hook portion and is plastically deformed, and the separating portion is broken, thereby separating from the lid body and projecting from the finger hook portion. It becomes smaller, and it can be displayed outside that the container has been opened.

[0013] Since the separating portion is provided so as to protrude in the radial direction of the lid main body, a large bending moment can be applied through the engaging piece by opening the opening / closing lid, and can be easily performed with a small operating force. Can be broken.

[0014] When the engaging recess of the upper opening is formed in the finger hook, the hook engages with the engaging recess, so that the engaging piece further projects from the finger hook during the opening display. It becomes smaller and the opening indication can be clarified.

When the container is opened, the engaging piece that can be removed through the opening is separated from both the lid body and the opening / closing lid, thereby making the opening indication clearer and the appearance of the opening / closing lid after opening is better. can do.

If the lid body is prevented from loosening via the ratchet, the lid body cannot be removed from the container, and fraudulent acts on the contents in the container can be more effectively prevented.

If an inner rib fitted to the annular rib of the lid body is provided on the opening / closing lid, the opening / closing lid can be lightly locked in a closed state by fitting the inner rib to the annular rib. Can be protected.

If a notch is formed on the stopper surface of the opening / closing lid corresponding to the finger hook, the notch is used to close the opening / closing lid.
Even if the contents adhere to the step of the lid main body, it can be effectively prevented from being scattered. The stopper surface contacts the step to define the fully closed position of the open / close lid.
This is because the cutout portion does not come into contact with the stepped portion, and there is no risk of inadvertently sandwiching the attached content.
