Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of an upper lid for opening a mouth of a drink can.
[0002]
[Prior art]
When opening the mouth of a conventional drink can, the tab provided on the top lid of the can is raised with a fingertip, and using the lever principle, the mouth of the top lid is plucked open at the tip of the tab. ing.
However, it is common sense today that structural problems are occurring when tabs are raised at the fingertips, such as when nails are long, women with weak fingertips, or even fingertips hurt even men. .
For this reason, many assistive devices that can be opened have been invented and used.
However, even if the auxiliary device is a very convenient tool to open, it must always be carried around.
[0003]
[Problems to be solved by the invention]
The present invention does not use a conventional auxiliary tool for opening a drinking mouth, makes it easy for a person with weak power to easily open the lid, and without changing the structure of various tabs currently on the market. It is intended that the same method of raising a tab and opening a drinking mouth can be easily used by performing a film sheet .
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the upper lid of the drink can of the present invention is an upper lid of a drink can having a tab fixed by an opening and a caulking pin, and a finger hole and an caulking pin between the tab and the upper lid. While sandwiching a triangular thin film sheet formed of a polymer material provided with a play hole through which is inserted, when lifting the tab, first fold both ends of the film sheet, while picking it with your fingertips, Means are provided to raise the tip of the tab on the finger hole side so that the fingertip can be easily inserted.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
[0006]
According to the present invention, when the tab 2 is caulked with the caulking pin 3 to the upper lid 1b without changing the structure of the conventional tab 2, the thin film sheet 4 is attached to the tab 2 of the tab. By inserting the film sheet 4 in a form in which a wrapping cloth is spread on the lower surface side and the film sheet 4 is inserted between the tab 2 and the upper lid 1b and packing is inserted, It can be employed in a drink can having a conventional tab structure, and can be manufactured by a conventional manufacturing facility by adding a step of inserting a film sheet into the conventional drink can manufacturing facility.
[0007]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1, 2, 3, 4, and 5 .
[0008]
As shown in FIG. 5 , in the conventional drink can, the tab 2 is firmly caulked to the upper lid 1b of the drink can with a caulking pin 3, and is fixed while maintaining the vacuum state of the drink can 1a. Accordingly, the tip of the finger is inserted into the finger insertion portion under the hole of the tab finger hole 7a, the tab 2 is caused with the caulking pin 3 as a core, the tab lever tip 7b is brought into a lever state, and the can opening 1d of the upper lid 1a. The method of prying open is taken.
[0009]
The present invention is different from the operation sequence in which the opening 1d is opened by the above-described method, that is, unlike the conventional method in which the tab finger hole 7a is directly raised by the finger 9 or the like by inserting a nail or the like, First of all, by inserting a triangular film sheet 4 made of a polymer material such as nylon, polyester, vinylon, acrylic, etc. into the entire lower surface of the tab 2 in the form of spreading a furoshiki , Before performing the operation of inserting the finger 9 into the tab finger hole 7a, the both wings of the film sheet 4 are raised at the fingertips, and then the tab 2 is wrapped with both pleats of the film sheet 4, and the finger holes 5a, 5b Are stacked, the finger of the left hand 8 is inserted into the finger holes 5a and 5b , the tab finger hole 7a of the tab 2 is pulled upward, the tab finger hole 7a at the tip of the tab 2 is slightly lifted, So that the finger 9 in the tab finger hole 7a It adopts a way to open the entrance to open ports 1d.
[0010]
Accordingly, when the tip of the finger 9 is inserted into the tab finger hole 7a, which has been regarded as a problem in the past, and the tip of the tab 2 is lifted, the tip of the finger 9 cannot be easily inserted into the lower surface of the tab 2. It has become possible to easily avoid problems such as the force of the initial action of lifting the arm is strong.
[0011]
Next, another major feature of the present invention is that the play hole 6 for inserting the caulking pin 3 through the film sheet 4 is formed larger than the diameter of the caulking pin 3 (see FIGS. 1 and 3). The influence of the insertion of the sheet 4 can be eliminated, and the caulking state of the caulking pin 3 and the tab 2 can be maintained in the same state as a conventionally employed method not using a film sheet as in the present invention. In addition, the same caulking effect and airtight state as in the prior art can be reliably maintained.
[0012]
Also, by adopting a high-tensile and elastic fiber product of polymer material for the film sheet 4, the tab 2 can be inserted into a thin sheet with a certain amount of waist without being bulky, and a thin aluminum plate Rather than adopting, we were able to make it a safe drink can without injury.
[0013]
Also, in the case of a metal plate, it is troublesome to return the raised sheet to its original flat state, but in the case of a polymer material, it is not complete when you release your hand, but it returns to its original position due to repulsive force. There is no obstacle when drinking, the effect is great.
[0014]
FIG. 4 shows the operation of the hand, finger, etc. for opening the ideal tab of the present invention, but the finger holes 5a, 5b may be pulled upward at first with a finger. It is only necessary to pull a little upward to ensure a gap for inserting a finger, and it is desirable to take care of each person's power.
[0015]
【The invention's effect】
In the present invention, since the film sheet is crimped together with the tab in advance, when a drink can is purchased from a vending machine or the like, it is difficult to lift the tip of the tab without using an instrument. Anyone can easily lift the tip of the tab and easily insert a finger into the tip of the tab, and there is no need to open the tip of the tab directly with a finger as in the prior art. Therefore, it does not require the strong force required for the initial movement, and it can be easily opened by women, weak people, and elderly people.
[0016]
In addition, there was no need to carry an auxiliary device to pry the tip of the tab, and a drink can adapted to the lifestyle of modern people could be provided.
[0017]
In addition, the risk of damaging nails was reduced for people with long nails, and the effect doubled.
