適したリング形状にせしめることもできる。Referring to FIG. 1, the container lid, generally designated by the numeral 2, includes a metal body 4 and a tensioning ring 6 connected to the body 4.
Contains. The main body 4, which can be formed from a suitable metal plate such as an aluminum-based alloy plate, a chromic acid-treated steel plate, or a tin plate, includes a circular top wall 8, a cylindrical skirt wall 10 depending from the periphery of the top wall 8, and A projecting piece 12 is provided extending downward from a part of the lower end of the skirt wall 10. The tension ring 6 is formed separately from the main body 4 and is integrally connected to the free end of the protruding piece 12 of the main body 4 by a suitable method such as a mechanical seaming connection, welding, or gluing. Projecting piece 12 of main body 4 and this projecting piece 1
A reinforcing rib 14 is formed at the connecting portion between the tension ring 2 and the tension ring 6. The tension ring 6 can be formed from a suitable metal plate such as an aluminum base alloy plate, a chromic acid treated steel plate or a tin plate, or from a suitable synthetic resin such as polyethylene or polypropylene. If desired, instead of connecting a separately formed tension ring 6 to the protruding piece 12 of the body 4, the protruding piece 12 itself can be enlarged to a size suitable for grasping it with the fingers, and also if necessary The free end of the protruding piece 12 itself, enlarged accordingly, can also be shaped into a ring suitable for placing a finger on.

。A pair of weakened lines 18 and 20 are formed from each of the notches 16, extending upward through the skirt wall 10 and then extending through the top wall 8. The pair of weakened lines 18 and 20 may be so-called perforations formed by forming slits (cut grooves) in the metal plate at intervals in the extending direction, but it is possible to reduce the thickness of the metal plate. It is convenient to have a so-called score composed of .

ている。Referring to FIG. 2, a synthetic resin liner 22 is provided on the inner surface of the top wall 8 of the main body 4. The liner 22 is made of a polyolefin resin such as polyethylene or a suitable synthetic resin material such as polyvinyl chloride by a method known per se (for example, the method disclosed in Japanese Patent Publication No. 19886/1986). It is conveniently formed by stamping directly onto the inner surface. The illustrated liner 22 has a relatively thin center portion 24 and a relatively thick peripheral portion 26. And this peripheral part 2
6 is formed with two annular protrusions, namely an annular sealing protrusion 28 located on the outside and an annular auxiliary protrusion 30 located on the inside.

It is important that 1≦2.650. Height hl is 1.
If it is smaller than 95 m², as will become clear from the description below, the impact resistance is insufficient and the seal tends to be damaged when processed in a vending machine. On the other hand, the height h
Even if l is made excessively large, it does not particularly contribute to improving the impact resistance, and the problem arises that the amount of material used increases and the cost increases. The amount of protrusion, that is, the height of the annular auxiliary protrusion 30 may be the same as that of the conventional one, and the height h2 of the annular auxiliary protrusion 30 with respect to the inner surface of the top wall 8 of the main body 4 may be about 1.45n. The thickness tl of the peripheral edge 26 itself of the liner 22 may be 0.35t*≦t1≦o and 55 mm, as in the conventional case.

。In the illustrated embodiment, the outer circumferential surface of the annular sealing ridge 28 extends substantially vertically at a distance from the inner surface of the skirt wall 10 of the main body 4 . On the other hand, the annular sealing protrusion 28
The inner circumferential surface extends downwardly and radially outwardly. More specifically, the base of the inner peripheral surface of the annular sealing ridge 28 extends at a relatively large angle of inclination α, and the free end extends at a relatively small angle of inclination β. The above inclination angle α is 45
degree≦α≦55 degrees (and the above inclination angle β is 5 degrees≦β≦1

3≦1.15m1, o, somm≦t2≦0.65m1
That's fine. The outer circumferential surface of the annular auxiliary protrusion 30 extends downward and radially inward at an inclination angle T. The above-mentioned inclination angle T may be 45 degrees≦T≦55 degrees. On the other hand, the inner peripheral surface of the annular auxiliary protrusion 30 extends substantially vertically.

せしめる。Continuing the explanation with reference to FIG. 3, the container M is attached to the crown opening 32.
2 to seal the crown opening 32.
The container lid 2 is fitted onto the lid 2 and pressed downward with a required pressure, thus bringing the peripheral edge 26 of the liner 22 into close contact with the top of the crown opening 32. As a result, the annular sealing ridge 28 and the annular auxiliary ridge 30 formed on the peripheral edge 26 are deformed into the shape shown in FIG.
It is brought into close contact with the outer peripheral surface of the top. While maintaining the above state, bend the lower end of the skirt wall 10 inward, and
As shown in the figure, it is locked into the locking jaw part 34 of the crown opening 32.

The present inventors speculate as follows. That is, according to the container M2 according to the present invention in which the height of the annular sealing protrusion 28 is increased, as shown in FIG. The space between the outer circumferential surface of 32 and the inner circumferential surface of the skirt wall 10 in the body 4 of the container lid 2 is almost completely filled by the annular sealing ridge 28, and the remaining void 36 is significantly smaller. Therefore, the boundary area between the top wall 8 and the skirt wall lO in the main body 4 of the container M2 or the skirt wall 1
It is presumed that even if a considerable impact is applied to the upper half of the body 4, the deformation of the main body 4 is sufficiently suppressed by the presence of the annular sealing protrusion 28, thereby improving the impact resistance.

The lower ends of 18 and 20 are broken off. Next, the tension ring 6 is pulled upwards or backwards to advance the breaking of the pair of weakened lines 18 and 20. After the pair of weakened lines 18 and 20 are almost completely ruptured, when the tension ring 6 is further pulled upwards or backwards, the arc-shaped skirt wall 10 is displaced upwardly and outwardly, and the crown Annular locking jaw 34 of mouth 32
Thus, the entire container lid 2 is removed from the crown opening 32.

For each item, use a 120-grade glass bottle with the following zero, fill the glass bottle with sulfuric acid and sodium carbonate so that the internal pressure after sealing is 4 Vol, and insert the cap into the container. Attached the lid. Next, using a vending machine sold by Matsushita Reiki Co., Ltd. under the product number "N5-N1:M," each glass bottle was repeatedly conveyed seven times from the storage position to the outlet. Afterwards, the number of leaks was determined. The results were as shown in Table 1 below.
