あった。In such a conventional can mouth closing device, first, after pulling the ring-shaped knob of the sealing member with a finger to remove the sealing member, the ring-shaped knob of the plug is pulled with a finger to remove the plug. However, since the ring-shaped knob of the plug did not protrude much higher than the bottom surface, it was difficult to put a finger. Therefore, it is conceivable to make the ring-shaped knob piece of the plug protrude upward, but if it is simply raised, the bottom wall of the sealing member becomes an obstacle. If the concave portion is to be deepened, the height of the entire plug body may be increased, and there is a possibility that an automatic supply device to the can mouth cannot be used as a can lid. In addition, when the ring-shaped knob of the plug is raised, there is a problem that the finger catches the ring-shaped knob of the plug when the ring-shaped knob of the sealing member is pulled with a finger.

状部2iの外径は山部1gの内径より大に設定されている。An embodiment of the present invention will be described below with reference to FIGS. The synthetic resin plug 1 includes a bottom wall 1a, a side wall 1b, and a flange 1c. A recess 1d is formed in the center of the bottom wall 1a of the plug 1. A ring-shaped knob piece 1e located horizontally is integrally formed from the bottom surface of the plug 1 in the recess 1d. The upper end of the ring-shaped knob 1e protrudes upward from the upper surface of the bottom wall 1a. This is because a certain height is required when the ring-shaped knob 1e is injection-molded. The outer diameter of the upper part 1b 'of the side wall 1b of the plug 1 is set slightly larger than the inner diameter of the can mouth 5, and the lower part 1b'
b "The outer diameter is set to be slightly smaller than the inner diameter of the can mouth 5, and a ridge 1f protruding outward is formed at the boundary of the outer surface, and a ridge 1g protruding inward is formed at the boundary of the inner surface. The metal sealing member 2 made of aluminum, tin, etc.
It is formed of a bottom wall 2a, a side wall 2b, and a flange 2c. The center of the bottom wall 2a protrudes upward, so that the upper portion of the ring-shaped knob 1e of the plug 1 can be stored. ing. The protruding portion of the bottom wall 2a of the sealing member 2
A ring-shaped knob 2f is formed by the circular space 2e. The inner and outer peripheral edges of the ring-shaped knob 2f are bent toward the lower surface to form bent portions 2g and 2h. Side wall 2b of sealing member 2
Is formed with a convex portion 2i protruding outward. The outer diameter of the convex portion 2i is set to be larger than the inner diameter of the peak portion 1g.

山部1gの弾性を利用してその下方へ位置させ、缶蓋４が
構成される。山部1gと凸状部2iにより栓体１と封緘部材
２とが輸送中等に外れることはない。Thus, the sealing member 2 is fitted into the plug 1, and the convex portion 2i is positioned below the convex portion 2g by utilizing the elasticity of the mountain portion 1g, thereby forming the can lid 4. The plug 1 and the sealing member 2 do not come off during transportation or the like due to the peak portion 1g and the convex portion 2i.

ととなった。Next, the can lid 4 is fitted into the can mouth 5. At this time, since the lower portion 1b "of the side wall portion 1b of the plug 1 is set to be slightly smaller than the inner diameter of the can mouth 5, the lower portion 1b" is easily fitted first, and the peak portion 1f contacts the can mouth 5. When it is set in the horizontal state and pressed further downward from this state, the ridge 1f and the upper portion 1b ″ of the side wall 1b are elastically deformed and fitted into the can mouth 5 to obtain the state shown in FIG. By using the side wall portion 1b of the plug 1, the operation of inserting the plug 1 can be smoothly automated.

栓体１を缶口５から容易に取外すことができる。With the can lid 4 fitted in the can mouth 5 in this way, as shown in FIG. A closure device is configured. The expanding device 6 includes an expanding claw 6a ', a pressing member 6b, and a pressing guide 6c. When the pressing member 6b is pulled up, the expanding claw 6a is expanded and the side walls 1b and 2b are expanded.
The tip of the expanding claw 6a coincides with the protruding portion 2i of the sealing member 2 so that the side wall 2b can be smoothly expanded. Although the side wall 2b of the sealing member 2 is plastically deformed, the side wall 1b of the plug 1 is elastically deformed.
When the sealing member 2 is opened, the side wall 1b of the plug 1 is restored and the plug 1 can be easily removed from the can port 5.

する。To open the can mouth closing device, first, a finger is hooked on the ring-shaped knob piece 2f of the sealing member 2 and pulled upward, whereby the bottom wall portion 2a of the sealing member 2 is broken toward the side wall portion 1b. Further, with this, the side wall portion 1b is deformed inward and the sealing member 2
Then, the finger is hooked on the ring-shaped knob 1e of the plug 1 and pulled upward, whereby the plug 1 itself is elastically deformed and removed from the can 5 to complete the opening.

Is formed so as to protrude slightly upward substantially in line with the outer diameter of the ring-shaped knob 1e of the plug 1, and insert the upper portion of the ring-shaped knob 1e of the plug 1 into the protruding portion. The height of the ring-shaped knob 1e of the plug 1 can be increased without increasing the overall height of the plug 1. As a result, the automatic supply device to the can mouth 5 can be used as the can lid 4 as in the past, and the ring-shaped knob 1e of the plug 1 can be easily hooked and pulled by the finger.
Can be easily removed from the can 5.
