Abstract

PURPOSE:To easily open a can by setting required intervals respectively between a tab lift part and a can lid body and between a point of application for pushing down a score part of the tab and the can lid body. CONSTITUTION:A predetermined distance l1 is specified between a tab 3 provided on a can lid body and a panel face 4, as well as a lift part 6 of the tab 3 is formed in a tapered shape wherein the lower face 6a is tilted upward as coming outward. A required distance l2 is specified between an upper face of a point of application 7 part of the tab 3 and the panel face 4, while the point of application 7 part is formed in a tapered shape wherein the lower face 7a is tilted upward as coming outward. l1 is preferably set to 1.0 to 3.0mm, while l2 is preferably set to 2.0 to 3.5mm. Thus it is easy to insert a finger (f) between the lift part 6 of the tab 3 and the panel face 4 and also it is easy to lift the tab. Further the tab 3 can be lifted upward with slight force thereby opening a can easily.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a configuration in which a can lid body is provided with a tab, and by lifting this tab, a score portion formed on the can lid body is pushed down. stay-on tab (SOT)
) type of can lid.

[Conventional technology]

Generally, as shown in FIG. 3, this kind of stay-on tab type can lid has a can lid body 1 provided with a tab 3 that is movable upward while being supported by a fulcrum 2. 3, the panel surface 4 of the can lid body 1
It is known that a score line 5 is formed in the following. By lifting the lifting portion 6 of the tab 3 upward, the point of action 7 of the tab 3 pushes down the score portion 8 inside the score line 5 of the barrel surface 4 to open the can. It has become.

[Problem to be solved by the invention]

By the way, in the case of the above-mentioned stay-on tab type can lid, as shown in FIG. Another problem is that it is difficult to insert the finger f into this gap. In addition, since the gap between the action point 7 and the score section 8 of the tab 3 is narrow, when lifting the lifting section 6 of the tab 3 with your finger to open a can, the finger f is moved between the lifting section 6 of the tab 3 and There is a problem in that it is necessary to continue applying a large force from the time the tab 3 is inserted into the gap between the tab 3 and the can to open the can.

The present invention has been made in view of the above circumstances, and its purpose is to make it easy to insert a finger between the lifting part of the tab and the panel surface of the can lid body when opening a can, and to provide a constant To provide a can lid which can be opened easily and smoothly without the need for a large force because the action point of the tab does not come into contact with the score part while lifting the lifting part to an angle. .

[Means to solve the problem]

In order to achieve the above object, the can lid of the present invention has a predetermined distance between the lifting part of the tab and the main body of the can lid when the can is closed, and an action of pressing down the score part of the tab. A required distance is set between the dot part and the can lid body.

[Effect]

In the can lid of the present invention, the predetermined interval set between the lifting part of the tab and the can lid main body makes it easy to insert a finger into the interval when opening the can, and the tab's Due to the required spacing set between the point of action that pushes down the score part and the can lid body, the point of action of the tab and the can lid body do not come into contact until the tab is lifted at a certain angle. After the tab can be lifted with a small force and the tab can be firmly grasped with fingers, the action point of the tab contacts the score section of the can lid body and smoothly moves the score section downward. Press down.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 and 2. These figures show cross-sectional views taken along the center line Q in the plan view of the can lid in FIG. 3.

Further, the same reference numerals are given to the parts having the same structure as those of the conventional example shown in FIG. 4, and the explanation thereof will be omitted.

In this embodiment, as shown in FIG. 1, a predetermined distance e is set between the tab 3 and the panel surface 4, and the lifting portion 6 of the tab 3 increases outwardly. Its lower surface 6. & is formed in an upwardly tapered shape.

Further, a required interval C7 is set between the upper surface of the point of action portion 7 of the tab 3 and the panel surface 4, and the lower surface 7a of the point of action portion 7 is inclined upward as it goes outward. It is formed into a tapered shape.

Note that the above interval Q1 is 1. It is preferable to set the rate at Qiu+ to 3.0 degrees. Because the interval Q1 is 1.011
If it is smaller than M, insert your finger f and 30
If it is larger than xx, a problem arises in that the lifting portion 6 is likely to be caught during handling during transportation.

Moreover, the above-mentioned interval is 2. Qxz~3,5! It is preferable to use codfish. This is because if the distance Q is smaller than 20cm, there will be a problem that the point of action 7 will come into contact with the panel surface 4 before the tab 3 is sufficiently lifted, and if it is larger than 3.5zx, the tab Even if the can is lifted sufficiently, the point of action 7 does not come into contact with the panel surface 4 and the can cannot be opened smoothly.

In the can lid configured as described above, the lifting portion 6 of the tab 3 is lifted, and the point of action 7 of the tab 3 is connected to the score portion 8.
When opening a can by pushing down the tab 3, a predetermined distance Q1 is set between the tab 3 and the panel surface 4, and the lifting portion 6 of the tab 3 increases outwardly as the lower surface 6 of the tab 3 increases.
Since the finger a is tapered upwardly, the finger f
can be easily inserted between the lifting part 6 of the tab 3 and the panel surface 4 (and the lifting part 6 can be easily lifted).
A required distance is set between the upper surface of the point of action section 7 and the panel surface 4, and the point of action section 7 is arranged outwardly (the lower surface 7a of the edge is inclined upward to form a tapered shape). As shown in FIG. 2, until the panel surface 4 of the score section 8 comes into contact with the point of action section 7 (until the tab 3 is lifted at a certain angle), a light force is applied. In addition to being able to lift the tab 3 upwards with the touch button, the tab 3 stands up to some extent after making contact, making it easy to apply force to the finger f.
By applying sufficient force to the tab 3 in a short period of time, the score portion 8 can be pushed down smoothly and reliably, and the can can be opened easily.

〔Effect of the invention〕

As explained above, the can lid of the present invention has a predetermined distance between the lifting part of the tab and the main body of the can lid when the can is closed, and an action point of the tab that pushes down the score part. Since the required interval is set between the can lid body and the can lid body, the predetermined interval set between the lifting part of the tab and the can lid body allows the lid to fall within the above interval when the can is opened. In addition to being easy to insert your finger into, the required spacing between the point of action of the tab that pushes down the score section and the can lid body allows the point of action of the tab to remain until the tab is lifted at a certain angle. Since there is no contact between the part and the can lid body, it is possible to lift the tab with a small force, and after the tab can be firmly grasped with fingers, the point of action of the tab is attached to the can lid body. By contacting the scoring section and smoothly pushing the score section downward, the can opening operation can be easily performed.
