Then, a support spring 9 is projected from the lower surface of the second inward flange, and the lower end of the support spring is engaged with the upper surface of the first inward flange 3. The support spring 9 is for elastically supporting the second inward flange 8, and as the support spring 9, an elastic piece curved in the circumferential direction as shown in the drawing is used in the circumferential direction from the lower surface of the second inward flange 8. A plurality of protrusions may be provided with an interval of and the lower part of the elastic piece may be placed on the upper surface of the first inward flange 3, or a coiled spring surrounding the mouth and neck portion 4 may be used.
[0009]
The short cylindrical portion 10 is erected from the inner edge of the flange hole of the second inward flange 8, the first sawtooth 11 is provided around the outer surface of the short cylindrical portion, and the upward stepped portion 12 is formed on the inner surface of the lower portion of the short cylindrical portion. Then, the upper surface of the upward stepped portion is engaged with the lower surface of the first engaging protrusion 6.
Further, a plurality of second engaging protrusions 13 are provided vertically on the inner surface of the lower part of the tapered tube 7 so that the second engaging protrusions are engaged with the engaging grooves 5 so as to be movable up and down.
[0010]
C is a cap, and an inner peripheral wall 14 having an internal thread on the inner surface is removably screwed to the outer surface of the container body neck portion 4, and the outer peripheral wall 15 is suspended from the upper outer surface of the inner peripheral wall via an outward flange-like connecting wall. A second saw-tooth 16 that engages with the first saw-tooth 11 when the cap is screwed is provided around the inner surface without meshing with the first saw-tooth 11 when the cap is screwed.
The first serrated teeth 11 and the second serrated teeth 16 are formed so that the first serrated teeth 11 move downward from the second serrated teeth 16 by pushing down the operating cylinder B against the elasticity of the support spring 9. Form to be removable.
[0011]
Further, the upright cylinder 17 is erected from the upper end of the inner peripheral wall 14, and the upper surface of the upright cylinder is closed by the top wall 18. Then, the first hanging wall 19 hanging from the lower inner surface of the standing cylinder 17 is brought into watertight contact with the upper surface of the outward engagement flange 22 of the later-described extraction cylinder 21 and the second hanging wall 20 hanging from the lower surface of the top wall 18. Is detachably fitted to the outer surface of the upper end of the dispensing cylinder.
[0012]
21 is a pouring tube, and the lower part of the tube is fitted to the inner surface of the upper end of the mouth-and-neck part 4, and the outward engagement flange 22 protruding from the outer surface of the lower part of the cylinder is placed on the upper surface of the mouth-and-neck part 4, and A downward stepped portion 23 is formed with the inner surface of the cylinder upper end portion having a small inner diameter.
[0013]
24 is an upright column, the column is raised from the center of the upper surface of the engagement plate 25 with which the upper surface of the plate is engaged with the lower surface of the downward stepped portion 23, the upper end of the column is protruded from the upper surface of the dispensing cylinder 21, and A plurality of long grooves 26 are provided vertically on the outer surface of the column portion, and the outer surface of the partition wall between the long grooves is slidably engaged with the upper inner surface of the extraction tube 21. Further, an upper small-diameter spiral spring 27 is projected from the outer peripheral portion of the lower surface of the engagement plate 25, and the lower end of the spiral spring is fitted to the inner surface of the lower end portion of the extraction tube 21 to urge the engagement plate 25 upward.
[0014]
Next, the operation of this embodiment will be described.
In order to close the cap C from the opened state shown in FIG. 2, the cap C may be fitted to the outer surface of the mouth neck 4 and screwed in the clockwise direction. Two serrated teeth 16 are fitted to the outer surface of the first serrated teeth 11. FIG. 1 shows this state.
If the cap C is rotated in the screwing direction to open from the closed state shown in the figure, the second serrated teeth 16 mesh with the first serrated teeth 11 so that the opening is impossible.
[0015]
In order to open the cap C, it is only necessary to push down the operating cylinder B against the elasticity of the support spring 9. Then, the first sawtooth teeth 11 are detached downward from the second sawtooth teeth 16, and the cap C Can be turned in the screwing direction.
Since the cap C is lifted by turning in the screwing direction, even if the operating cylinder B is lifted by the elasticity of the support spring 9 by releasing the pressing of the operating cylinder B in the middle of opening, the first saw-shaped The teeth 11 do not mesh with the second serrated teeth 16.
[0016]
【The invention's effect】
In the container with a cap according to claims 1 and 2, an operating cylinder is provided on the peripheral wall of the container body so as to be movable up and down, a first sawtooth is formed on the outer surface of the operating cylinder, and a cap screw is formed on the inner surface of the outer peripheral wall of the cap. Since the second serrated tooth that meshes with the first serrated tooth at the time of disengagement and the first serrated tooth is detachable downward from the second serrated tooth by pressing the operating cylinder downward, the cap is Even if it is going to turn in the closing direction, it is impossible unless the operation cylinder is pressed downward. Therefore, it is possible to prevent the occurrence of fouling due to mischief of the child.
