Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has been made so that when a beverage in a beverage can, such as juice, coffee or beer, is to be drunk, a stay-on tab which is opened upward by raising can be easily caused. The present invention relates to a stay-on tub can lid and an opening member used therefor.

[0002]

2. Description of the Related Art At first, the easy-open type of can lid for beverage cans is a so-called pull-tab type in which a tab is completely separated from a can lid body to open the can. In the can lid, there was a danger that the separated tab pieces were scattered and had an adverse effect on the environment, and might also damage limbs and the like. For this reason, recently, the so-called stay-on tab type can lid has become mainstream, in which the tab is raised from the can lid body without completely separating the tab and the opening piece is pushed into the can.

[0003] Fig. 11 shows the basic structure of a conventional general stay-tab type can lid. A tab 23 for pushing the opening piece 22 into the can is provided on the can lid body 21 of the beverage can.
However, the connecting portion 23a cut and raised into a substantially C shape is rivet 2
4, and are attached. Opening piece 2
2 is surrounded by a groove engraved with a part left in the can lid body 21. In the conventional general stub tab lid having such a configuration, when the annular trigger portion 23b formed at one end of the tab 23 is raised upward with the fingertip of the hand,
The lever 23 operates on the tab 23 with the connecting portion 23a as a fulcrum. Then, the opening piece 22 receives the pressing force by the tip portion 23 c of the tab 23, and the portion where the groove is engraved becomes the can lid body 2.
The part cut from 1 and not grooved is bent inside the can as a hinge, forming an opening in the can lid body 21. After the opening is made, tab 2
3 is bent in the original direction. By doing so, the beverage inside can be poured out from the opening of the beverage can and can be drunk.

However, due to its structure, for example, in the basic configuration of FIG. 11, the tab 23 is attached substantially parallel to the can lid body 21. Cause part 2
3b, the gap between the tab 23 and the leading end portion is short, and the lever 23 is operated on the tab 23 so that the leading end portion 23c of the tab 23 can be removed. Opening piece 22 through can lid body 21
A relatively large force is required to cut off from
Thus, the conventional general stay-on tub can lid,
There is a structural problem that it is difficult to raise the tab upward.

[0005] For this reason, when a conventional general sion tub can lid is used for a beverage can, the elderly, women and children have a large percentage of people with weak fingers. There is a problem that struggles to cause. In particular, women
She often stretches her nails for fashion and applies nail polish on her nails, and it's easy for such women to hurt their nails or peel off their nail polish when they cause tabs .

Therefore, a conventional technique for opening the can lid body with a relatively small force is disclosed in Japanese Utility Model Registration No. 3013877 and Utility Model Registration No. 300.
No. 7692, JP-A-7-232732 and JP-A-9-290827
And Japanese Patent Application Laid-Open No. 2000-16425.

As shown in FIG. 12, the prior art described in Japanese Utility Model Publication No. 3013877 has a tip formed so as to be inserted into a gap between a tab 32 attached to a can lid main body 31 and the can lid main body 31. Tab 3 using a can opener 34 having a portion 34a and the other end 34b formed so as to be pressed by a finger.
By inserting the distal end portion 34a into the gap between the can lid body 2 and the other end portion 34b and then pushing down the other end portion 34b, the distal end portion 34a pushes up the triggering portion of the tab 32, and the distal end portion of the tab 32 opens from the can lid body 31. An opening is formed in the can lid main body 31 by pressing and cutting a groove engraved around the piece 33 and pressing the opening piece 33 into the inside of the can.

The basic concept of the prior art described in Japanese Utility Model Registration No. 3007692 is substantially the same as the technology of FIG. 12, and as shown in FIG. A mounting portion main body 41 formed so as to be insertable into a gap with the can lid, and is attached to one end of the mounting portion main body 41 so as to be openable and closable. Using a can opener 43 having a pressing portion 42 having a support portion which is a fulcrum of a lever in contact with the upper peripheral portion, the mounting portion main body 41 is inserted into the gap between the tab attached to the can lid main body and the can lid. By subsequently depressing the pressing portion, the mounting portion body 41
Pushes up the trigger of the tab, presses and cuts the groove formed around the opening piece by the tip of the tab, and pushes the opening piece into the can to form an opening in the can lid body That is.

[0009] As shown in Figs. 14 (a) and 14 (b), the one described in Japanese Patent Application Laid-Open No. 7-232732 discloses an opening action portion 51a.
When using a hook portion 51b, an opening device 51 and a lifting portion 51c, and the outer portion 52a ₁ of the lead portion 52a of the tab 52, the inner portion 52a ₂ and the hook portion 51b, 5
Hooked at 1b and attached to the can lid main body 53, lift the opening tool lifting portion 51c to raise the raising portion 52a of the tab 52, and push down the tip portion 52b of the tab 52 via the opening action portion 51a. Thus, the groove formed around the opening piece 53a is pressed and cut, and the opening piece 53a is bent inside the can to form an opening in the can lid body 53.

According to these prior art can lid opening devices,
In each case, the length in the longitudinal direction is longer than the length from the raised portion to the tip portion of the tab, so that the tab can be raised with a relatively small force to form an opening in the can lid body. Further, according to the one described in JP-A-7-232732, since the opening tool is previously attached to the can lid in advance,
When the can is opened, the trouble of using an opening tool separate from the can lid can be omitted.

[0011] Further, in the device described in Japanese Patent Application Laid-Open No. 9-290827, as shown in FIGS. 15 (a) and 15 (b), a finger hook 62 which can be raised upward is provided on the fingertip side of the tab body 61. By forming the tab by being rotatably mounted in a hinge shape, the finger hook 62 can be lifted upward and pinched when the opening piece 63a of the can lid body 63 is opened. As shown in FIGS. 16A and 16B, the finger hook 6 is inserted into the guide hole 61a provided on the fingertip side of the tab 61.
The tab is formed by inserting both ends of the can 2 so as to be slidable in the horizontal direction, so that the finger hook portion 62 can be opened when the opening piece 63a of the can lid body 63 is opened.
, So that it can be easily picked out by protruding outside the outer peripheral edge. According to this technique, when the tab of the can lid is caused, the nail is not hurt and the tab can be safely pinched with a relatively small force with the finger of the hand and the can lid is easily opened. In addition, since the opening is integrally attached to the can lid in advance, the trouble of using the opening separately from the can lid can be omitted, and the tab is stored within the diameter range of the inner circumference of the can lid. As a result, the storability of the entire can is not impaired.

In the apparatus described in JP-A-2000-16425, a pair of guide members 72 are provided on a can lid main body 71 as shown in FIGS. Member 72
It is supported so as to be able to slide above the opening piece 71a of the can lid body 71, and a projection 73a is provided at an end of the lower surface on the opening piece 71a side,
A slide member 73 provided with raised portions 73b and 73c is fitted into both ends of the upper surface. Also, the opening piece 71
a is provided with a concave portion 71b at the center thereof, and the upper surface of the concave portion 71b is formed by an inclined surface downwardly directed from the end 71c near the bent portion of the opening piece 71a toward the opposite side. A portion 71d is provided. Then, as shown in FIGS. 17B and 17C, by sliding the slide member 73 in the direction of the end 71c of the can lid main body 71, the protrusion 73a of the slide member 73 comes into contact with the engagement portion 71d. The opening 73 can be pushed into the inside of the can. According to this technique, since the slide member 73 is integrally attached to the can lid main body 71, without using a separate opening tool from the can lid main body 71,
The can lid can be opened.

[0013]

However, all of those described in Japanese Utility Model Registration No. 3013877 and Japanese Utility Model Registration No. 3007692 are tools that are separate from the can lid, and are easily removed. In addition, in order to open the can lid, it is necessary to have a regular, and further, every time it becomes necessary to open the can lid, these opening tools must be taken out and attached to the tab, which is inconvenient. There is a problem.

Further, in the apparatus described in Japanese Patent Application Laid-Open No. 7-232732, since the opening tool is fixed in a state protruding from the outer peripheral edge of the can lid, it can be stored in a vending machine or a large number of cans can be stored in a case. The protruding portion is caught when packing the cans, or the stability when the cans are stacked vertically is impaired, resulting in poor storage. In addition, if it protrudes from the outer peripheral edge of the can lid, there is a problem in that the protruding portion collides with a person or an object and may cause harm.

Further, Japanese Patent Application Laid-Open Nos. 9-290827 and 2000-1
No. 6425, the above-mentioned utility model registration No. 301387
No. 7, Japanese Utility Model Registration No. 3007692, Japanese Unexamined Patent Publication No. 7-2327
Although these problems inherent in the Japanese Patent Publication No. 32 can be solved, the structure of the can lid or the tab itself is completely different from the structure of the conventional general stay-ion tab as shown in FIG. In order to change to another, a new mold and machine for manufacturing a can lid must be provided. In addition, since the structure for enabling the end of the tab to be rotatable or for sliding the tab in the lateral direction is complicated, there is a problem that the manufacturing cost and the manufacturing burden of the can lid increase accordingly. . Further, in the device described in Japanese Patent Application Laid-Open No. 2000-16425, since the slide member 73 is fitted into the guide member 72, a relatively large amount of force is required to slide the slide member 73. The raised portions 73c and 73d that are pushed by a finger when sliding are not so protruded from the upper surface of the slide member 73, so that there is a problem that it is difficult to push with a finger.

Further, when the opening tool described in Japanese Utility Model Registration No. 3013877 or Utility Model Registration No. 3007692 is integrally attached to the can lid in advance, the same as that described in Japanese Patent Application Laid-Open No. 7-232732 is used. Then, one end of the opening tool protrudes from the outer peripheral edge of the can lid. However, as described above, beverage cans are often stored in a vending machine or a large number of cans are packed in a case. Therefore, if a part of the can is protruded, the storage ability is deteriorated. Also, if there is a protruding portion, there is a risk of injury or damage to a person or an object.

As described above, techniques for opening the can lid main body with a relatively small force have been conventionally proposed, but in any case, the person opening the can lid needs to carry extra equipment. It is inconvenient to use, impairs the storage and storage of cans before opening, and has a high risk of causing harm when colliding with people or objects. Since the basic structure of itself is changed, it cannot be applied to existing can lid manufacturing equipment and can lids, and any of the problems such as an increase in work and economic burden in the production of can lids are inherent. I was

Therefore, the present invention has been made to solve all the problems of the prior art as described above.
With a simple configuration, it can be widely applied to conventional general beverage stain tub can lids, minimizing manufacturing burden,
In addition, without impairing the storage and storage characteristics, without having to carry a portable device, even for people with relatively weak fingers such as the elderly, women and children, tabs can be operated with simple operation and minimal force. Can be opened to open the can lid for beverages, in particular, a person who has stretched his nails can not hurt his nails or hurt the nail polish painted on his nails. It is an object to provide an opening member to be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Prior to the description of embodiments of the present invention,
The basic concept of the present invention will be described with reference to FIGS. FIG. 1 is a schematic configuration diagram showing an example of an opening member used for a stay-on tub can lid according to the present invention. 2A and 2B are explanatory views of the state of the canion tub can lid according to the present invention. FIG. 2A is a plan view and a schematic cross-sectional view of the can lid showing a state where the thin plate-shaped member is stored in the can lid.
Is a plan view and a schematic cross-sectional view of the can lid showing a state where the thin plate-like member is slid to a position where the can lid is opened, and (c) is a schematic view of a can lid showing a state where the can lid is opened by the thin plate-like member. It is sectional drawing.

The stay-on tub can lid of the present invention is constructed by attaching a thin plate-like member A as shown in FIG. 1 to a conventional general stay-on tub can lid shown in FIG. The thin plate-shaped member A is provided with a space A1 slidable in a predetermined direction in a state surrounding the raising portion B1 of the tab B between both ends. One end A2 is curved upward.
Further, the other end A3 is provided with a locking portion A4 which restricts the slide by the abutment portion B1 of the tab B contacting. Further, the other end A3 is located at a position where the opening piece C1 of the can lid body C is pushed during the opening operation, and the one end A2 projects outside the outer peripheral edge C2 of the can lid body C by a predetermined length. . In addition, it is preferable that a concave portion A5 is formed near the engaging portion A4 of the other end portion A3 so that the inducing portion B1 of the tab B can be fitted therein. The other end A3
Is made of a material that allows the opening piece C1 to be easily pushed open, and the one end portion A2 makes the thin plate-shaped member A slide in a predetermined direction so as to easily jump out of the outer peripheral edge C2 of the can lid body C. For this reason, it is preferable that each is made of a material which is easily elastically deformed. Further, it is desirable that the space portion A1 be bent to have a shape conforming to the shape of the stay tub, because the space portion A1 can be housed in a state where the can cover does not protrude from the can cover body C when the can cover is not opened.

The opening operation by the can lid of the present invention to which such a thin plate member A is attached will be described with reference to FIG.
At the time of storage, as shown in FIG. 2A, the thin plate-shaped member A is stored inside the outer peripheral edge C2 of the can lid body C.
At this time, the space portion A1 of the thin plate-shaped member A surrounds the leading portion B1 of the tab B with play. When the can lid is opened from this state, when the thin plate-shaped member A is slid to the one end A2 side, when the other end A3 is positioned above the opening piece C1, as shown in FIG. The raising portion B1 of the tab B comes into contact with the locking portion A4 of the other end portion A3, and further sliding is restricted. At this time, the raising portion B1 of the tab B is fitted into the concave portion A5, and the movement is regulated. Also, at this time, the one end A2 jumps over the outer peripheral edge C2 of the can lid body C and projects outside the can lid body C by a predetermined amount while being elastically deformed. When the one end A2 is pushed up from this state, as shown in FIG. 2 (c), the lever B works to push up the inducing portion B1 of the tab B and also push down the tip B2 of the tab B to open the opening piece C1. , And the other end portion A3 of the thin plate member A pushes the opening piece C1 to open the can lid. When the thin plate-shaped member A is slid by a predetermined amount and then pushed up to operate the lever principle, the lid of the stainless steel tub can can be easily opened with a small force without damaging the claws.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 is a plan view showing one embodiment of a stay-on tub can lid according to the present invention. FIG. 4 is an explanatory view of a main part of FIG.
(a) shows a can lid in an initial state as a beverage can, (b) shows an operation start state for opening the can lid, and (c) shows a state when the can lid is opened. FIGS. 5 to 9 are explanatory views of a main part showing a modification of the stay-on tub can lid of the present embodiment.

As shown in FIG. 3, in the stay-ion tub can lid of this embodiment, the tab 3 for pushing the opening piece 2 into the can lid body 1 is cut and raised into a substantially C-shape. Part 3a
Are connected via a rivet 4 and attached. The opening piece 2 is a groove 2 engraved with a part left in the can lid 1.
a. When the ring-shaped raising portion 3b formed at one end of the tab 3 is raised with the fingertip of the hand, the lever 3 works on the tab 3 with the connecting portion 3a as a fulcrum. Then, the opening piece 2 receives the pressing force by the tip 3c of the tab 3, and the portion where the groove 2a is cut is cut from the can lid body 1 and the portion where the groove is not cut functions as a hinge. As a result, it is bent inside the can and an opening is formed in the can lid body 1. After the opening is formed, the raising portion 3b of the tab 3 is bent in the original direction. Thereafter, the beverage inside can be poured out from the opening of the beverage can and can be drunk.

That is, the stay-on tub can lid of this embodiment is
By raising the raising portion 3b of the tab 3 having the annular raising portion 3b and fixed to the can lid 1, the tip 3c opposite to the raising portion of the tab 3 has an opening formed in the can lid 1. It is configured so that the piece 2 is pushed in and opened. In this regard, the configuration is the same as that of the conventional general stay tub can lid shown in FIG.

The difference between the stay-on tub can lid of the present embodiment and the conventional one is that a thin plate-like member 5 as described below is attached to the raising portion 3b of the tub 3. .

The thin plate-shaped member 5 has a thin plate-shaped surrounding portion 6 which surrounds the raising portion 3b with play in the longitudinal direction. The thin plate-shaped member 5 is inserted with a play into a space surrounded by the annular portion of the tab 3 provided inside the raising portion 3b. In addition, as shown in FIG. 4, the thin plate-shaped member 5 and the surrounding portion 6 are separated from each other to such an extent that the raising portion 3b of the tab 3 can be inserted with play. For this reason, the thin plate-shaped member 5 is slidable along the longitudinal direction without coming off the raising portion 3b of the tab 3. Note that the thin plate-shaped member 5 is not necessarily limited to the above configuration as long as it can slide along the longitudinal direction without coming off the raising portion 3b of the tab 3.

The thin plate member 5 has a length L in the longitudinal direction.
1 is formed longer than the length L2 between both ends of the tab 3 (between the end of the raising portion 3b and the tip 3c).

The thin plate member 5 is formed such that the length L1 in the longitudinal direction when viewed from above is shorter than the diameter L3 of the inner circumference of the can lid body 1.

The enclosing portion 6 is provided with a locking portion 6a on the end 3c side of the tab 3 of the both ends.
Raise the thin plate member 5 from the tip 3c of the tab 3
b by sliding in the direction toward
When the end 5a on the tip 3c side of the tab 3 is located above the tip 3c of the tab 3, the locking portion 6a comes into contact with the trigger 3b of the tab 3, and the tip of the tab 3 of the thin plate member 5 The sliding of the thin plate-shaped member 5 in the direction from the portion 3c toward the raising portion 3b is further restricted.

In the surrounding portion 6, a locking portion 6b is provided on the raising portion 3b side of the tab 3 of both ends in a state of being connected to the thin plate-like member 5. Is slid in the direction from the raising portion 3b of the tab 3 toward the tip 3c, so that when the thin plate-shaped member 5 is located inside the outer peripheral edge 1a of the can lid body 1, the locking portion 6b , And restricts further sliding of the thin plate-shaped member 5 in the direction from the raised portion 3b of the tab 3 of the thin plate-shaped member 5 toward the tip end.

As described above, the stay-on tab can lid of the present embodiment slides the thin plate-shaped member 5 to the opposite side of the tab 3 from the raising portion 3b, thereby forming the inside of the outer peripheral edge 1a of the can lid main body 1. The thin plate member 5 is slid to the tab 3b side of the tab 3 so that one end 5a of the thin plate member 5 pushes the tip 3c of the tab 3 to open the opening piece 2.
Is brought into a position where the tab 3 can be pushed into the can, the other end 5b protrudes outside the outer peripheral edge of the can lid body 1 by a predetermined length, and the other end 5b is raised upward, so that the tab 3
Is configured to be able to cause the inducing portion 3b.

Further, as shown in FIG. 3, the thin plate-shaped member 5 preferably has such a width that it can be picked up by a finger of a hand or pushed up by a finger of a hand. In this embodiment, the width of the thin plate-shaped member 5 is large enough to be picked up by the fingers of the hand and pushed up by the fingers over the entire space between both ends of the thin plate member 5. It is sufficient that the width has the above-described width over a predetermined range near the end 5b on the part 3b side.

The end 5b of the tab 3 on the side of the raising portion 3b of the thin plate-like member 5 is arranged along the raised portion of the outer peripheral edge 1a of the can lid body 1, as shown in FIG. If formed in a curved shape, the thin plate-shaped member 5 is
When the tab 3 is slid to the raising portion 3b side, the end 5b of the thin plate-like member 5 becomes the outer peripheral edge 1a of the can lid body 1.
This is preferable because it is easy to jump over the outside of the vehicle and easily pick it with the fingers of the hand.

The thin plate-shaped member 5 is formed of a material having such a strength that at least a portion in contact with the tab 3 when being caused to undergo elastic deformation without plastic deformation.
It should be noted that the material may be formed of metal, synthetic resin, or any other material as long as the material has a strength such that the portion in contact with the tab 3 is elastically deformed without plastic deformation.

As shown in FIG. 4, the surrounding portion 6 of the thin plate member 5 is formed so that the end of the tab 3 on the tip 3a side of the tab 3 is not closed with respect to the tab 3. Have been. The enclosing portion 6 may be formed so that one of the two end portions is not closed. The enclosing portion 6 is formed such that the end of the tab 3 on the side of the raising portion 3b is not closed, and the locking portion is formed. 6a may be formed so as to be connected to the thin plate member 5.

If the thin plate-like member 5 protrudes above the outer peripheral edge 1a of the can lid main body 1, there is a danger that the thin plate-shaped member 5 will obstruct the storage of the can in a vending machine or the like. Therefore, as shown in FIG. 5, the raising portion 3b of the tab 3 is inclined with respect to the top surface of the can lid body 1 so that the thin plate-shaped member 5 is substantially parallel to the top surface of the can lid body 1. Is preferred.

Further, as shown in FIG.
The end 5a on the tip 3c side of the tab 3 and the portion on the locking portion 6a side, including the surrounding portion 6, are connected to the outer peripheral edge 1a of the can lid body 1.
In the state where it is stored inside, it is good to bend so that it may become almost parallel to the top surface of can lid main part 1. The surrounding portion 6 is preferably formed so as to be elastically deformed, because the surrounding portion 6 does not hinder the sliding of the thin plate-shaped member 5.

Further, as shown in FIGS. 7 to 9, when the surrounding portion 6 is formed into a leaf spring shape which is pressed against the raising portion 3b of the tab 3, it is possible to prevent the surrounding portion 6 from jumping upward. It is preferable because it can be used.

When drinking the beverage contained in the beverage can provided with the stay-on tub can lid of the present embodiment thus constructed, the thin plate-shaped member 5 is moved from the state of FIG. The lid body 1 is slid to the tab 3b side of the tab 3.
Then, as shown in FIG. 4 (b), one end 5a of the thin plate-shaped member 5 pushes the tip 3c of the tab 3 of the can lid body 1 to a position where the opening piece 2 can be pushed into the inside of the can. When it comes, the tip 3c of the tab 3 of both ends of the enclosing part 6
The locking portion 6a provided at the end on the side abuts on the raising portion 3b of the tab 3 so that it can no longer slide in the same direction. Also, at this time, the other end 5b of the thin plate-shaped member 5 protrudes outside the outer peripheral edge of the can lid body 1 by a predetermined length, and can be picked up by a finger or pushed up by a finger. .

Here, when the end 5b of the thin plate member 5 is picked up with the finger of the hand and raised upward, or pushed up with the finger of the hand,
Due to the principle of leverage, the raising portion 3b of the tab 3 is pushed up, and the opening piece 2 receives a pressing force by the tip 3c of the tab 3. Further, as shown in FIG. 4C, when the tab 3 is pulled up by a predetermined amount, a force is applied by the end 5a of the thin plate-like member 5 to push down the tip 3c of the tab 3, and the groove 2a is closed. 1 and bent inside the can lid 1 to form an opening 6.

The end 5a of the thin plate member 5 is connected to the tab 3
Because it is located on the front end 3c, it does not block the opening and does not hinder the drinking of beverages. In addition, since the surrounding portion 6 of the thin plate-shaped member 5 surrounds the raising portion 3b of the tab 3 with play, the entire thin plate-shaped member 5 is rotated 90 degrees when drinking a beverage, and is completely rotated. It is sufficient that the opening is not obstructed.

As described above, the thin plate member 5 according to the present embodiment
Plays a role of an opening tool of the stay-on tub can lid 1.

At this time, since the thin plate-like member 5 of this embodiment is longer than the length between the raising portion 3b and the tip 3c of the tab 3, the raising portion 3 of the tab 3 is directly pinched with the finger of the hand. The tab 3 can be raised upward with a smaller force than when the tab 3 is raised. Moreover, the thin plate-shaped member 5 is
Since the portion that comes into contact with the tab 3 when it is raised is made of a material having such a strength as to be elastically deformed without being plastically deformed, the tab 3 can be reliably raised.

The end 5a of the tab 3 on the side of the raising portion 3b of the thin plate-like member 5 is curved along the raised portion of the outer peripheral edge 1a of the can lid 1, and Has a width that can be picked up by the finger or pushed up by the finger of the hand, so that the thin plate-like member is slid and the end portion 5b of the thin plate-like member 5 jumps out of the can lid body 1. In addition, the thin plate-shaped member 5 is easily pinched and raised with the finger of the sliding hand or pushed up with the finger of the hand. For this reason, when a woman who stretches her nails or applies nail polish on her nails opens the can lid of this embodiment, she does not hurt her nails or damage the nail polish applied to her nails.

When a beverage can having a stay-on tub can lid according to the present embodiment is housed in a vending machine, a case, or the like, as shown in FIG. Of the can lid body 1 so that it can be stored inside the outer peripheral edge 1a of the can lid body 1. In this way, the thin plate-shaped member 5 can be stably stored in a vending machine, a case, or the like, and when the can is discharged to the take-out opening in the vending machine, the thin plate-shaped member 5 is removed. Is not caught in the middle and does not hinder the discharge.

Further, the thin plate member 5 of this embodiment surrounds the raising portion 3b along the longitudinal direction through the surrounding portion 6 with play and does not separate from the can lid body 1,
Since it is integrally attached, there is no need to carry it like an opening device separate from a conventional can lid, and there is no risk of loss, and it does not add complexity to those who drink canned beverages. In addition, since it is enclosed with play, the thin plate-shaped member 5 can be easily formed.
Can be slid.

The thin plate member 5 according to the present embodiment as described above
Is a tab 3 manufactured in a conventional manufacturing process of a can lid.
It can be used as it is without any change in the specifications of the can body and the tab of the conventional ordinary tub, so that the production burden and the waste of the production cost can be minimized. it can.
Further, since one end of the enclosing portion 6 of the thin plate-shaped member 5 is not closed with respect to the tab, the thin plate-shaped member 5 is manufactured separately, The thin plate-like member can be attached to the tab 3 such that the unclosed end of the stainless steel tab can lid passes through the raising portion 3b of the tab 3. For this reason, a conventional general machine for manufacturing a stainless steel tub can lid can be used as it is, and further, a thin plate-shaped can also be used for a conventional can lid having a beverage already contained therein. Since the member can be attached, it can be applied to an extremely wide range of conventional beverage tub can lids and cans having the same.

At this time, as shown in FIGS.
If the thin plate-like member and the surrounding portion are prevented from protruding above the can lid body, the storability of the can in a vending machine, a case, or the like is not impaired.

In general, it is necessary to use both hands to open the can lid, such as holding the can with one hand and pulling up the tab with the other hand. Therefore, it is inconvenient for a person who cannot release both hands at the same time, such as a driver running a car, to stop the car in order to open the can lid. However, opening the can lid while driving a car is extremely dangerous because it may cause an accident by releasing both hands or performing an unreasonable operation with one hand. For this reason, there is a demand for a can lid that can be easily opened with one hand for drivers and other people who are driving a car.
