The cap must be able to completely prevent milk leakage so that milk does not leak if the bottle falls. The leakage prevention means adopted by the present invention is as follows. I. A ring-shaped protrusion is provided along the outer circumference of the tubular foot portion of the cap. The tube diameter of the foot and the length of the protrusion of the protrusion are determined so that the tip of the protrusion can be in close contact with the inner peripheral surface of the mouth wall. This close contact prevents milk leakage. B. A ring-shaped convex portion is provided on the lower portion of the tubular foot portion along the outer circumference of the foot portion. The tube diameter of the foot portion and the position, shape and size of the convex portion are determined so that the convex portion can be brought into close contact with the concave surface of the lower portion of the step portion formed on the inner peripheral surface of the mouth wall. This close contact prevents milk leakage. Also, the cap is prevented from rising. The stepped portion is a conventional paper stopper receiving portion,
It is always present in conventional milk bottles with paper stoppers, along with the concave surface at the bottom of the step. C. The lower part of the outer peripheral surface of the tubular foot portion is formed into a slope inclined inward, and the guide of this slope allows the outer peripheral surface of the foot portion to be in close contact with the tip of the stepped portion formed on the inner peripheral surface of the mouth wall. ,
Determine the tube diameter of the foot. This close contact prevents milk leakage and also prevents the cap from rising. D. The means (a) and the means (b) or the means (c) can be used in combination.

It has flexibility and elasticity. By properly selecting the length of the protrusion of the protrusion (8), the tip of the protrusion is in close contact with the inner peripheral surface of the mouth wall (5) of the bottle to prevent milk leakage. Figure 5a
The action of the convex portion (9) will be described with reference to Fig. 1. By pushing the cap from the mouth, the lower slope (1
3) hits the tip of the stepped portion (10), and the convex portion (9) passes the tip of the stepped portion (10) while being pressed inward.
It closely contacts the concave surface (11) at the bottom of the step, which prevents milk leakage. Also, by being blocked by the step,
The cap does not rise. The action of the slope (12) of the foot (7) will be described with reference to FIG. 5b. When the cap is pushed, the slope (12) hits the tip of the step (10) and the lower part of the foot is pressed and squeezed. Slope (1
Guided by 2), the outer peripheral surface of the foot portion (7) comes into close contact with the tip of the step portion (10). Due to the elasticity of the cap material, the step (1
Since 0) and the foot (7) are pressed against each other, milk leakage is prevented and the cap does not lift.
