侵入することがない。(E) Action According to the can mouth protection cover (4) of the present invention, when the pressure inside the can is high, the inner diameter of the side wall (4f) is larger than the maximum outer diameter of the side surface (2c) of the can mouth (2). Since the gas is set in the can, the gas in the can is completely surrounded by the side wall (4f) and the side surface (2
c) Ventilation can be performed downward through the gap with the entire circumference, and it is not necessary to form a ventilation hole in the upper portion of the side wall (4f). In addition, the locking projections (4) formed inside the lower end of the side wall (4f).
a) Ventilation part (4h) downward by notching multiple points in g).
Since (4j) is formed, the gas flowing downward from the gap between the inner circumference of the side wall (4f) and the entire circumference of the side surface (2c) of the can mouth (2) passes through the ventilation parts (4h) and (4j). It flows from below to the outside, which allows smooth ventilation between the inside of the can and the outside. When the pressure inside the can becomes lower than the outside, ventilation is performed in the opposite state. In this way, since the ventilation to the inside of the can is performed from the lower surface of the can mouth protection lid (4), rainwater does not enter into the can during transportation or storage unlike the conventional case.

（２）から取外すことができる。In addition, ventilation holes (4h) and (4j) are formed by cutting out a plurality of locking projections (4g) of the can mouth protection lid (4) to form ventilation holes just below the inside of the knob piece (4i). Since the part (4j) is wider than the other ventilation parts (4h) and is set to have substantially the same width as that of the knob piece (4i), it becomes easy to adjust the elasticity of the locking projection (4g), and When the pick-up piece (4i) is lifted and removed, it can be removed extremely easily from the can mouth (2) by the wide ventilation part (4j).

ている。(F) Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 is a tin top plate that forms the upper surface of the can.
Reference numeral 2 denotes a can mouth, which is fixed to a part of the top plate 1 by caulking the lower end 2b, projects upward from the top plate 1, and has a side surface 2c for locking the cap with an elastic hooking piece all around. A groove 2d is formed, and an upper end 2a of the upper end thereof is wound inward and downward to form an opening 3. Reference numeral 4 denotes a can mouth protection lid made of a synthetic resin such as polypropylene, which comprises an upper wall 4a, a side wall 4f, and a knob piece 4i extending horizontally from the outer side of the upper end of the side wall 4f. The upper wall 4a has a flat upper surface and has two circumferentially extending cushioning projections 4b.
4c is formed. The cushioning ridges 4b and 4c float slightly above the upper end of the canister 2 in a state of being attached to the canister 2, and the vents 4d that do not project to the lower surface of the upper wall 4a at four locations. 4e. Can lid 4
The inner wall of the side wall 4f is set to be larger than the maximum outer diameter of the side wall 2c of the can mouth 2, and a locking projection 4g that locks in the concave groove 2d of the can mouth 2 is formed inside the lower end of the side wall 4f. There is. The locking protrusion 4g is the ventilation portion 4 of the cushioning protrusions 4b and 4c.
The ventilation portions 4h and 4j are formed so that the portions facing the d and 4e are notched and do not protrude from the inner surface of the side wall 4f. The ventilation portion 4j located immediately below the inside of the knob piece 4i is wider than the other ventilation portions 4h and is set to have substantially the same width as that of the knob piece 4i.

雨水が缶内に侵入することがない。According to such a can mouth protection lid 4, when the pressure inside the can is high,
Since the inner diameter of the side wall 4f is set to be larger than the maximum outer diameter of the side surface 2c of the canister 2, the gas in the can is vented downward through the gap between the inner surface of the side wall 4f and the entire side surface 2c of the canister 2. Therefore, it is not necessary to form a ventilation hole in the upper portion of the side wall 4f.
In addition, a locking projection 4g formed inside the lower end of the side wall 4f
Since the downward ventilation portions 4h and 4j are formed by cutting out a plurality of portions of the above, the gas flowing downward from the gap between the entire inner circumference of the side wall 4f and the entire circumference of the side surface 2c of the can mouth 2 is the ventilation portions 4h and 4j.
It flows out from the lower side to the outside through j, thereby smoothly venting the inside and the outside of the can. When the pressure inside the can becomes lower than the outside, ventilation is performed in the opposite state. In this way, since the ventilation to the inside of the can is performed from the lower surface of the can mouth protection lid 4, rainwater does not enter the can during transportation or storage as in the conventional case.

上げて取外す際に幅広の通気部４ｊにより極めて容易に
缶口から取外すことができる。In addition, a plurality of venting portions 4h and 4j are formed by cutting out a plurality of locking projections 4g of the can mouth protection lid 4, and the venting portion 4j located immediately below the inside of the knob piece 4i is wider than the other venting portions 4h. Since the width of the knob piece 4i is set to be almost the same, the locking projection 4g
It is easy to adjust the resilience, and when the picking piece 4i is lifted and removed, it can be extremely easily removed from the can mouth by the wide ventilation part 4j.
