Abstract

PURPOSE:To prevent pollution from being generated, and at the same time, improve environmental preservation or the hygienic aspect by a method wherein a notch is provided on a finger placing part of a finger ring provided on a pull lid, and by separating this notch on the side opposite to the peripheral direction, a gap is formed at the finger placing part, and a can lid is fitted in this gap. CONSTITUTION:When a finger is placed in a finger ring 4, and the finger ring 4 is pulled outward, a pull lid 3 is cut off from a can lid 2 along a tear groove 2c, and the finger ring 4 and the pull lid 3 are removed from the can lid 2 together. After removing the finger, if a notch 4'' on the finger ring 4 is slightly separated by fingers on the side opposite to the peripheral direction, a part between finger placing parts 4a and 4b is expanded, and a gap 1 is generated. At this time, one finger placing part of the finger ring abuts on the inner peripheral wall surface of the can lid, and the tip of the other finger placing part is fastened with the lower edge 2a' of a collar 2a on the outer periphery of the can lid. Under this condition, the finger ring pinches the inner peripheral wall surface of the can lid and the can simultaneously by restoring force of the finger placing parts to the original position. Therefore, the pull lid can be fix-fitted on the can lid.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a small sliding lid formed on the can lid of a can containing a beverage such as juice or beer, which can be attached to a beverage can. It is related to the device.

BACKGROUND OF THE INVENTION The can lid of a conventional beverage can for juice, beer, etc. is provided with nine small lids that close an opening that serves as a drinking spout.

This lid has a finger ring for hooking a finger, and a bulge formed on the finger ring is fixed to the can lid with a pin.

If you hook your finger on the finger ring and pull it strongly, the lid will break along the break groove made in the can lid, forming an opening in the can lid that will serve as a drinking spout.

In addition, the lid removed from the can lid may be hung on the tip of a finger to drink juice or beer, or it may be disposed of in a nearby trash can or ashtray.

However, when people with no morals do not have containers such as trash cans or ashtrays, they throw their lids on the floors of public facilities, in parks, on beaches, or on the streets.

Also, recently, when I pulled the lid off the can lid, the tip of the lid was bent while a part of the lid remained attached to the can lid, and the lid entered the can and remained attached to the back of the can lid. There is something that is happening.

Problems to be Solved by the Invention In the former case, in which the lid is removable from the can lid, when there is no trash can or ashtray, or when it cannot be left attached to the fingertip, it can be used on the floor, on the beach, or on the street. Because the lids are thrown away, people can get injured by touching the lids, and wild birds and saltwater fish can swallow them.

In the latter case, the lid cannot be removed from the can lid, but from a hygienic perspective, the surface of the lid is designed to fit inside the can, so it does not stick to the outer surface of the lid. Drinking juice or beer that contains harmful bacteria can cause intestinal ulcers.

As mentioned above, in the former case, people without morals cause pollution and destroy the environment, and in the latter case, there are drawbacks such as unsanitary conditions.

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, the object of the present invention is to enable a lid removed from a can lid to be attached to the can itself, and to prevent the lid from accidentally separating from the can due to impact.

Means for Solving the Problems In order to solve the above object, the present invention provides a can lid having a sliding lid with a break groove formed on the can lid that covers a can for containing beverages such as juice or beer. In the sliding lid attachment device, a finger hook ring forming a notch in a finger hook for inserting a finger;
A bulging piece formed on the finger ring is fixed to the can lid, and when a finger is inserted into the finger ring and pulled, the lid is broken from the can lid to form an opening that serves as a drinking spout; In addition, the outer periphery of the can lid is fitted into the gap between the finger hooks that is created when both ends of the notch of the finger hook are separated in the opposite direction to the circumferential direction, and one side of the finger hook is attached to the can lid. and the tip of the other finger hook part is locked to the lower edge of the flange on the outer periphery of the can lid, and in this locked state, the finger hook part attempts to return to its original position. The elasticity of the can clamps the inner peripheral wall surface of the can lid and the can, thereby fixing the attachment of the can lid.

If you insert your finger into the finger ring that is fixed to the lid formed on the can lid that is crowned by the working can and pull it strongly outward, the lid will be cut along the break groove so that the lid can be peeled off from the can lid. , the finger ring and the lid are removed from the can lid together.

Then, remove your finger from the finger ring and slightly release it from the notch made in the finger ring of the finger ring in the opposite direction to the circumferential direction. part occurs.

By applying this gap to the outer periphery of the can lid and pushing it in, the finger ring can be fitted onto the can.

At this time, one of the finger hook portions of the finger hook ring comes into contact with the inner peripheral wall surface of the can lid, and the tip of the other finger hook portion is latched to the lower edge of the flange on the outer periphery of the can lid.

In such a locked state, the finger hooks simultaneously clamp the inner peripheral wall surface of the can lid and the can due to their elasticity as they tend to return to their original positions.

Therefore, the sliding lid can be fixedly attached to the can lid.

Example An embodiment of the present invention will be described below with reference to the drawings.

In the figure, Fig. 1 is an enlarged sectional view of the main parts, and Fig. 2 is an overall perspective view of a can 1 for holding beverages such as juice or beer, and a can lid 2 provided on the can 1 with a sliding lid 3 attached. It is.

FIG. 3 is an enlarged side view of a main part showing the mode of notches 4' formed in the finger hooks 4a, 4b of the finger hook ring 4. FIG.

FIG. 4 is a plan view of the finger ring 4. FIG.

The can 1, the can lid 2, and the finger ring 4 are mainly made of materials such as aluminum and iron.

Until juice or beer (not shown) is added to can 1,
Can lid 2 is not covered.

Conventionally, there is a machine dedicated to crimping (not shown), so after placing the can lid 2 on top of the can 1, this machine exclusively for crimping can 1.
The can lid 2 is crimped onto the can lid 2 to keep it in a fixed state.

When the can lid 2 is attached to the can 1 in this manner, the outer peripheral wall surface 2b' of the can lid 2 slightly forms a flange 2a.

When not drinking the juice or beer in can 1,
An opening 2c serving as a drinking spout is closed with an open can 3.

A pin 5 is attached to the protruding piece 4'' that forms this sliding lid 3 on the finger hook ring 4.
It is fixed by caulking or welding.

Therefore, when the finger hook ring 4 is pulled outward, the can lid 2 can be pulled along the break groove 2d formed to match the shape of the lid 3.
Since the open can 3 is removed together with the finger ring 4, an opening 2c serving as a drinking spout can be formed.

In addition, the finger ring 4 fixed to the sliding lid 3 may be cut, for example, as shown in Figure 3A, or made thin enough to break even if bent, as shown in the opening in the same figure. Notch 4
'' is bored so that the finger ring body 4 can be divided into finger hook parts 4a and 4b.

In this way, the notch 4'' can be expanded in the opposite direction to the circumferential direction.

The outer periphery 2' of the can lid 2 can be fitted into the slight gap 1 between the finger hooks 4a, 4b created when the finger hooks 4a, 4b are expanded without being pushed.

At this time, one finger hook 4a of the finger hook ring 4 is in contact with the inner peripheral wall surface 2b of the can lid 2, and the tip 4b of the other finger hook 4b is in contact with the inner peripheral wall surface 2b of the can lid 2.
' is locked to the lower edge 2a' of the flange 2a on the outer periphery of the can lid 2, making it difficult to separate.

Effects of the Invention As described above, in the present invention, a notch for forming a cutting or breaking groove or a thin wall so as to be easily broken is formed in the finger-holding portion of the finger-holding ring provided on the lid, and this notch is formed around the By separating them in the opposite direction, a gap is created between the finger hooks, so when the can lid is fitted into this gap, one of the finger hooks comes into contact with the inner peripheral wall surface of the can lid, and the other The tip of the finger hook is locked to the lower edge of the flange on the outer periphery of the can lid, and after the finger hook is expanded, there is an elastic force that causes the finger hook to return to its original position. Since the inner peripheral wall surface of the can lid and the can are held together at the same time, once the sliding lid is attached to the can lid, it can be held in a fixed state without accidentally detaching, which contributes to environmental protection and hygiene as well as prevention of pollution. Moreover, since the lid can be collected together with the can, it is useful as a recycled resource.
