Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The object of the present invention is to provide a spout means that can be used easily and hygienically in a container molded of an elastic material such as polyethylene resin.

(Structure of the Invention) Hereinafter, the invention will be described with reference to the illustrated embodiment. Reference numeral 2 is a cap rotatably fitted on the mouth wall 1 of a container formed of an elastic material. Convex legs on the top wall 21 of the cap
23 is provided vertically, and the stopper rod 3 is supported by the convex leg 23 in a horizontal and slidable manner along the diameter of the peripheral wall 22. The stopper rod 3 has a Marui nail head 31, and the total length of the stopper rod 3 must be shorter than the inner diameter of the peripheral wall 22 of the cap.

According to the example shown in the figure, a split groove 26 is provided below the support hole 25 of the stopper rod 3 in the convex leg 23 for the purpose of vertically attaching the stopper rod 3 to the top wall 21 of the cap and assembling the stopper rod 3 to the convex leg 23. There is this split groove 26
Is not always necessary. Further, the top wall 21 and the peripheral wall 22 of the cap are separately molded, and the cap 2 is formed by tightly fitting them together. However, the top wall 21 and the peripheral wall 22 may be molded integrally. It is possible.

According to this invention, the mouth wall 1 of the container is provided with the notch edge 11, and the nail head 31 of the stopper rod 3 is positioned above the notch mouth edge 11 and the nail head 31 and the convex leg 23 are provided. A spring 4 is interposed between them. Rod end of the stopper rod 3 on the peripheral wall 22 of the cap
At a position corresponding to 32, a spout 24 capable of fitting with the rod end 32 is bored.

A cutout 12 is formed in a part of the cutout edge 11 of the mouth wall, and the lower end of the convex leg 23 is the cutout as shown in FIG. 1, 2 or 3. Located at 12. Further, end walls 13 and 14 that can engage with the convex legs 23 are formed at both ends of the cutout 12.

On the other part of the cutout edge 11 of the mouth wall, a nail wall 15 is formed so as to be clearly seen from FIGS. 6 and 7.
The claw wall 15 has a crescent-shaped cross section formed by a part of the outer peripheral surface of the mouth wall 1 and a vertical plane 16 that can be engaged with the nail head 31, and the maximum thickness of the claw wall 15 and the total length of the stopper rod 3 are determined. Wa is a cap wall 22
It is set larger than the inner diameter of.

This invention is constructed as described above, and the plug bar 3 is supported horizontally and slidably along the diameter of the peripheral wall 22 by the convex leg 23 hung on the top wall 21 of the cap. , Its total length is shorter than the inner diameter of the peripheral wall 22 of the cap, and the spring 4 is interposed between the nail head 31 and the convex leg 23, while the nail head 31 is positioned above the cutout edge 11 of the mouth wall. positioned. Therefore, as shown in FIG. 3, the nail head 31 can be brought into close contact with the peripheral wall 22 of the cap to keep the plug rod 3 horizontal. On the other hand, on the peripheral wall 22 of the cap, the spout 24 is formed at the same angular position as the stopper rod 3 in the cap 2, but as described above, the total length of the stopper rod 3 is larger than the inner diameter of the peripheral wall 22 of the cap. Since it is short, the rod end 32 of the stopper rod is retracted inside the spout 24,
Is open. Therefore, if the container is pressed in this state, the contents are ejected from the spout.

Next, the cap 2 is rotated at the injection position as described above. A claw wall 15 is formed in another part of the cutout edge 11 of the mouth wall different from the cutout 12, and the claw wall 15 forms a part of the outer peripheral surface of the mouth wall 1 and the nail head 31 described above. Since it is formed in a comb-shaped cross section by a vertical plane 16 that can be engaged with the vertical plane 16, the vertical plane 16 is closely connected to the inner peripheral surface of the cap 2 at the left and right edges of the plane. Therefore, the nail head 31 of the stopper rod 3 rotating in the same phase as the cap 2 moves to the vertical plane 16 of the nail wall 15 as shown in FIG. The rod 3 moves forward. By the way, since the sum of the maximum thickness of the claw wall 15 and the total length of the stopper rod 3 is set to be larger than the inner diameter of the peripheral wall 22 of the cap, the peripheral wall 22 of the cap at the injection position is set.
The rod end 32 of the stopper rod retracted inward of the
It fits into a spout 24 that has been drilled in, and the spout 24 is closed by a rod end 32.

When the cap 2 is rotated again in the closed position as described above, the relative position between the nail wall 15 and the nail head 31 changes, and the nail head 31 is again engaged with the inner peripheral surface of the cap 2 by the tension of the spring 4. ,
Therefore, since the rod end 32 escapes from the pouring port 24, the rod end 32 returns to the open position again.

The nail wall 15 has a comb-shaped cross section as described above,
Therefore, since a kind of wedge is formed on the nail head 31 that transitions from the inner peripheral surface of the cap 2 to the vertical plane 16 of the nail wall 15, pushing of the rod end 32 that advances toward the spout 24 is performed. The pressure is very strong. Therefore, by appropriately selecting the dimensions of the spout 24 and the rod end 32 and the tension of the spring 4 with respect to the retracting force of the stopper rod 3 when moving from the closed position to the open position, a strong sealing of the spout 24 is achieved. It is possible to obtain sex.
On the other hand, since the nail head 31 is round, the movement of the nail head 31 from the inner peripheral surface of the peripheral wall 22 of the cap to the vertical plane 16 of the mouth wall or vice versa is smooth.

It should be noted that, as in the illustrated example, by appropriately selecting the positions of the end walls 13 and 14 of the notch groove in accordance with the size of the width of the vertical plane 16 of the claw wall 15, the injection position is changed to the closed position. , Or vice versa, the rotation angle of the cap 2 can be designed to be quite small. Further, it is convenient to use the cap 2 provided with an indication of the direction of the spout 24 shown by an imaginary line in FIG. 5 on the top surface thereof.

(Effect of the Invention) Thus, according to the present invention, the spout can be closed or opened from the inside by rotating the cap attached to the container opening of the acupressure injection container with the fingertip, and as described above. In addition, it is very hygienic because it can be easily obtained with a very high degree of sealing when closed, and there is no risk of the contents leaking even if an unexpected external force is applied. In addition, it is not necessary to remove the cap when using it, and it does not fall off and fall off. Therefore, it is most suitable as a pour-out container for medicines such as foods and cosmetics that are frequently used daily.
