Abstract

PURPOSE:To obtain a can with a stay-on-tab which does not come off the can and whose strength can be kept as same as a pull-tab can even with non- carbonic drink put in wherein inner pressure is low by a method wherein the tab is connected to a main body at one position and can be rotated with respect to the connection part as the center in a can. CONSTITUTION:A tab 3 is fixed to a main body 1 and a lid 2 wherein when the lid 2 is to be opened, the tab is raised in a direction (a) first and after a part of the lid 2 and the main body 1 are separated, the tab 3 is pulled along a direction (b) and rotated so that the lie 2 can be separated from the main body 1. Since the lid 2 and the tab 3 are shifted from a mouth, they may not disturb drinking. In addition, since the lid 2 is covered by the tab 3, injuring by the cut of the lid 2 can be prevented. Since the tab is constituted to be connected with the lid, force can be efficiently transmitted as force for pulling the lid from the main body so that the strength of a stay-on-tab can can be approximately equal to that of a pull-tab can even with non-carbonic drink put in whose inner pressure is low.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a stay-on tub can in which the lid does not separate from the can.

(Prior art) Conventionally, the lids of canned beverages such as juice and beer include pull-tab cans, which are used after being removed from the can, as shown in Figure 6, and stay-on tabs, in which the lid does not separate from the main body, as shown in Figure 7. There is a can. Currently, the majority of canned beverages produced in Japan are in pull-tab cans.

In FIG. 6, the pull-tab can consists of a main body 31, a lid 32 carved into a part of the main body 31, and a tab 33 attached to the lid 32. When opening the lid 32, the tab 33 is raised in the direction of the arrow a and pulled off, so that the lid 32 is separated from the main body 31.

Next, in FIG. 7, a conventional stay-on tub can consists of a body 41, a lid 42, and a tab 43 attached to the body 41. When opening the lid 42, the tab 43 is first raised in the direction of arrow a.

Since the tab 43 is attached to the main body, a force is applied to the lid 42 in the direction of pushing it into the can due to the principle of leverage.

The lid 42 is configured so that a portion of the notch is connected to the can body 41, so it can be attached to the can body 41 without being removed.
curves inward.

Next, by bending the tab 43 in the direction of the arrow, the tab 4
3 can be prevented from becoming an obstacle when drinking. At this time, the lid 42 is not connected to the tab 43, so it remains bent inside the main body.

(Problems to be Solved by the Invention) As canned beverages become more popular, pull tabs that are removed from cans are causing trouble.

There are also accidents where discarded pull tabs injure bare feet at beaches and other places, and endanger lives when they are swallowed by beds or cows on farms.

Conventional stay-on tabs have the same impact resistance as pull tabs for cans with high internal pressure such as carbonated drinks, but for non-carbonated cans such as coffee and oolong tea, the internal pressure is low and the strength is lower. There is a view that it may be more inconvenient than a pull tab. Also, some people find traditional stay-on tub cans unsanitary because the lid touches the contents of the can.

As described above, both pull tabs and conventional stay-on tabs had their own issues. This invention was made to solve these problems, and provides a stay-on tab can in which the tab does not separate from the can and has the same strength as a pull tab even when the internal pressure is low even with materials other than carbonic acid. The purpose is to

(Means for Solving the Problems) The present invention is intended to solve the above problems, and provides a can having a structure in which a tab and a main body are connected and can be rotated around the tab. Is this a can configured so that the tab remains connected to the can body, or a can with a string that connects the tab to the can body? (Function) In this invention, since the tab is connected to the lid, the force is efficiently transmitted as a force to peel off the lid from the main body, and the strength of the stay-on tab can can be increased even when the internal pressure is low even when using other than carbonic acid. It can be made similar to a pull tab.

(Example) Figure 1 is a block diagram of a rotary stay-on tub can.
In the figure, 1 is a can main body, 2 is a lid carved into a part of the main body 1, and 3 is a tab attached to the main body 1 and the lid 2. In order to open the lid 2, the tab 3 is first raised in the direction of the arrow a, the lid 2 and the main body 1 are partially separated, and then the lid 2 is separated from the main body 1 by pulling and rotating in the direction of the arrow. FIG. 2 is an open view of FIG. 1. In this way, the lid 2 and tab 3 are shifted from the drinking spout, so they do not get in the way when drinking.

Further, since the lid 2 is covered with the tab 3, there is no chance of injury from the cut end of the lid 2.

FIG. 3 is a diagram of a stay-on tub can configured so that the lid remains connected to the main body.

In the figure, 11 is a can body, 12 is a lid carved into a part of the main body 11, and 13 is a tab attached to the lid 12. When opening the lid 12, first raise the tab 13 in the direction of arrow a, partially separate the lid 12 and the main body 11, and then
The lid 12 can be opened by pulling it in the direction of the arrow. FIG. 4 is an open view of FIG. 3. In this way, the lid 12 and tab 13 are configured to be hidden in the opposite direction of the drinking spout.

Figure 5 is a diagram showing the structure of a string-type stay-on tab can.
In the figure, 24 is a string connection part and 25 is a string. The operation of opening the lid is performed by raising the tab 23 in the direction of arrow a and peeling it off.

This tab 23 and lid 22 are attached to a string 25 and a string connection part 24.
It is connected to the can body 21 by.

Effect of 0I) As described above, according to this invention, the tab does not separate from the can,
Since it has sufficient strength even when used in cans with low internal pressure, it can prevent accidents such as injuring bare feet on the beach or accidentally being swallowed by a bed, and also contributes to environmental beautification. Figure 1 is a top view of the rotating stay-on tab can, Figure 2 is a top view of the stay-on tab can shown in Figure 1 with the lid opened, and Figure 3 is a top view of the can with the lid open. A top view of a stay-on tab can configured so that the lid remains connected to the main body, Figure 4 is a perspective view of the stay-on tab can shown in Figure 3 with the lid opened, and Figure 5 is a string type can. FIG. 6 is a top view of a conventional pull-tab can, and FIG. 7 is a top view of a conventional stay-on tab can.
