る。2. Description of the Related Art As a can lid which is easy to open and has a tab and a tearing tongue that are difficult to separate from the lid body after opening, as shown in FIGS.
A can lid 100 of the type shown in FIG.
-69451). In the figure, 101 is a lid body,
102 is a score-like portion that defines the opening. The score section 102 has two ends 102a,
The portion between them is the missing portion 105. Reference numeral 103 denotes a ring-shaped knob tab, which is fixed to the rivet 104 of the lid body 101 via the tongue-shaped portion 103a. The head end 102b of the score portion is relatively close to the peripheral rising portion (so-called chuck wall) 101a of the lid body, and the nose portion 103b of the knob tab 103 is the head end 10 of the score portion.
It extends beyond 2b toward the chuck wall 101a.

い構造になっている。At the time of opening, when a finger is inserted into the knob tab 103 and a portion on the left side of the rivet 104 in the drawing is pushed up, the nose portion 103b pushes down a portion of the lid main body immediately thereunder, and at the same time, the rivet 104 is pulled up. Therefore, a shearing force acts on the head end 102b of the score portion, and the head end 102a and the vicinity thereof are broken to perform the initial opening. Subsequently, when the knob tab 103 is pulled up toward the left side of the drawing, the score portion 102 is torn, and a tearing tongue piece (not shown) is formed. Both ends 1 of the score part 102
Since there is a missing portion 105 between 02a, the tearing tongue is connected to the lid body 101 via the missing portion 105 even after the opening is completed, that is, the tearing tongue does not separate from the lid body 101. .

3c has a narrow width, and has an upper end 103c 1 and a lower end 103c.
c 2 becomes a bent portion and is bent. When the tab 103 is pushed up due to the opening and further pulled up, the lower end 103c 2 is subjected to reverse bending and at the same time a relatively strong tension is applied. Therefore, especially when the tab 103 is made of a relatively hard and brittle aluminum alloy plate, Bottom edge 10
3c 2 easily breaks. Therefore, the tab tab 103 may be separated from the tearing tongue during the tearing of the score portion 102, and the complete opening may not be performed, or the tab tab 103 may be detached from the lid main body 101 to cause a problem of damaging the environment. ..

き出しが起る。A positive pressure beverage such as a cola beverage is filled leaving the headspace (see 13 in FIG. 6) and the thumb is inserted into the tab 103 to open the beverage can sealed with the can lid 100. When the pick tab 103 is pushed up with the can, the can tilts so that the head end 102b of the score portion faces downward, but the head end 102a does not touch the chuck wall 101a.
Because it is relatively close to the head end 102
The beverage contacts the lower surface of b. Therefore, the beverage to which the internal pressure is applied is likely to be ejected from the initial opening portion, which easily causes troubles such as soiling the clothes. For example, with a can lid having a nominal diameter of 206 (the inside diameter of the fitting body opening end is 57.0 mm), a nominal diameter of 211 (the inside diameter of the body part is 6 mm).
When the neck-in can body (5.8 mm) is sealed (headspace height is about 10 mm), the above-mentioned spouting occurs at an inclination of about 10 degrees.

(See FIG. 6) is connected to the lid main body 1 at the missing portion 5, and is a portion 1 between the breaking end portion 6c and the main score portion 2.
It joins with the tab 3 at 4 '. Although the notch 5 and the portion 14 'are bent after opening, they are originally flat and therefore do not undergo reverse bending. Therefore, even if the lid body 1 is made of an aluminum alloy plate, its width is appropriately determined. If it does not break. Therefore, in the normal use state, the tab 3 and the tearing tongue piece 8 are not separated from the lid body 1.

Since it is greater than or equal to the length of 8b (substantially equal to L 2 ), the lower part 8b is hidden under the upper part 8a and thus the entire tearing tongue 8 is hidden under the pick tab 3 and is not exposed. Therefore, after opening, when the lip is applied to the mouth to drink the content liquid, there is no possibility that the nose head is injured or the inner surface of the tearing tongue is brought into contact with the mouth to cause discomfort.

The moving distance to the right of the figure after opening d is paragraph 00.
As described in 22, it is 2 × L 2 . Since the distance T between the tail end 3d of the knob tab 3 and the inner surface of the chuck wall 1a is larger than the moving distance 2 × L 2 , the tail end 3d of the knob tab 3 does not stick out of the double winding tightening portion 15. .. Therefore, when the cans after opening are placed on a table etc., there is less risk of knocking the cans by catching the protruding tabs on the body, and even when recycling, many cans are well-molded. It is easy.

おそれがない。When the knob tab 3 is pushed up at the time of opening, first, the score part 6 for vent is released.
It starts from a and is broken, and then the initial opening portion (head end) 2a of the main score portion is broken by the nose portion 3b of the pick tab. There is a considerable distance (usually about 7-10 mm) between the top 6a and the initial opening 2a. Therefore, when it is used as a can lid of a canned food filled with a positive internal pressure beverage, even when the can is slightly tilted and the surface of the content beverage is below the initial opening portion 2a when the thumb is inserted into the tab and the opening is performed. In the case where it is not below the top 6a of the score part for vent, the pressurized gas in the head space 13 is blown out instantaneously from the top 6a which is broken first, and the internal pressure of the can becomes substantially zero. Therefore, there is no possibility that the content beverage 12 will spout from the initial opening 2a of the main score part 2.

易にするためである。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1, 2 and 3, reference numeral 20 designates a can lid which is easily opened, and 1 designates a lid made of an aluminum alloy thin plate or a surface-treated steel plate such as tin-plated steel plate or tin-free steel. It is the main body. The lid main body 1 is formed with a main score portion 2 and a rivet 4 that define an opening 9 (see FIGS. 5 and 6) that serves as a drinking spout, a spout, and the like, and a knob tab 3 is fixed to the rivet 4. There is. The knob tab 3 has a ring portion 3a into which a finger can be inserted at the time of opening, and the nose portion 3b is directly above the initial opening portion 2a which is the head end of the main score portion 2 or the initial opening portion. It is located directly above a portion slightly inside (rivet 4 side) of 2a (in this case also, in this specification, the initial opening 2a is the nose portion 3b).
It is said to be directly below). This is to facilitate the initial breakage of the main score portion 2.

る。The main score portion 2 is substantially C-shaped, and a portion near the center of the lid body 1, that is, a portion facing the initial opening 2a is a missing portion 5 (FIG. 3). The initial opening portion 2a of the main score portion 2 is provided with the lid main body 1 so that the content beverage 12 (see FIG. 6) can be easily drunk and poured out.
Is relatively close to the chuck wall 1a. Portions near both end portions 2b of the main score portion 2 are curved outward (FIG. 3). Because of the opening, when tearing the main score portion 2 by chance, even if it tears with a strong force, the tearing surely stops at the end 2b. When tearing with normal force, the tearing, i.e. the opening, usually stops at the portion 2c of the main score portion 2 (FIG. 3; referred to herein as the opening end portion) where the cutout 5 is the narrowest. Both ends 2
A linear bead 7 that is recessed inward is provided between c. This is because after the opening is completed, the tearing tongue piece 8 can be easily bent at the missing portion 5. The bead 7 may be of a convex type on the outside. A shallow score portion 7 ′ (FIG. 4) may be provided instead of the bead 7. In addition, 1b is a recessed portion for making it easy to put a finger into the ring portion 3a when opening.

止まる。The lid body 1 further has a semicircular top portion 6a along the rivet 4 on the side of the missing portion 5, and both end portions 6b are relatively close to the main score portion 2 and slightly exceed the rivet 4. A sinusoidal Vent score portion 6 (FIG. 3) extending toward the initial opening 2a is formed. Portions near both end portions 6b of the vent score portion 6 are curved toward the missing portion 5 side (FIG. 3). This is because when the score portion 6 for vent is broken at the time of opening, even if it happens by a strong force, the break can be surely stopped at the end portion 6b. When breaking with normal force, the breaking usually stops at the lowest portion 6c of the curved portion (FIG. 3; referred to herein as the breaking end portion).

The distance L 1 between the straight line 14 connecting the two and the initial opening portion 2a of the main score portion 2, that is, the radial distance L 1 between the initial opening portion 2a and the break end portion 6c is equal to the distance between the straight line 14 and both opening end portions of the main score portion 2. The distance L 2 between the straight lines connecting the portions 2c, that is, the radial distance L 2 between the break end portion 6c and the opening end portion 2c (FIG. 3)
It is defined above. Further, the distance T (FIG. 2) between the tail end 3d of the tab 3 and the inner surface of the chuck wall 1a is a distance L 2 between the straight line 14 connecting both breaking end portions 6c and the straight line connecting both opening end portions 2c, that is, the breakage. It is set to be larger than twice the radial distance L 2 between the end portion 6c and the opening end portion 2c.
