Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a spouting head for a pump-type liquid spouting container.

2. Description of the Related Art Conventionally, a pump-type liquid ejecting container shown in FIG. 3 has been known as a container for taking out liquid or cream shampoo, rinse, etc. from a container body.

By pushing down the ejection head 3 which is vertically movable and protrudes upwardly from the container body 1 via the stem 2, the liquid inside the container is released from the nozzle cylinder 4 which protrudes from the front surface of the ejection head 3. It is designed to emit water. In addition, numeral 5 in the figure is a screw tube for fitting the stem which is vertically installed from the bottom surface of the spouting head 3, and when the container is not in use, it is screwed into the threaded member 6 on the side of the container body 1 to fix and hold the spouting head 3. ing.

By the way, in the case of conventional containers such as those mentioned above, the remaining liquid inside the nozzle cylinder may dry up after the container is used, causing the inside of the nozzle cylinder to become clogged, making it difficult to pour out the liquid properly. Taking this into consideration, the spout 7, which is removably fitted to the tip of the nozzle cylinder, may be attached integrally to the top surface of the ejection head 3 via an elastic piece 8 (see the imaginary line in the figure), or it may be installed separately from the ejection head part. A spout formed of a member is removably fitted thereto.

``Problems that the invention aims to solve'' However, in either case, the spout must be attached and removed each time it is used, and in the case where the spout is attached to the top of the jet head, it hangs down in front of the nozzle cylinder when the spout is opened. If the spout is completely removed, care must be taken to store the spout when using the container. It was always troublesome to use.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems by configuring a spout member to be effectively built into the ejection head.

"Means for Solving the Problems" In order to achieve the above object, in the present invention, as shown in the drawings, a threaded cylinder 15 for stem fitting is vertically disposed from the center of the bottom wall 14, and stands up from the periphery of the bottom wall. The head body 10 has a nozzle tube 17 protruding from the front part of the peripheral wall 16, and a ring-shaped part 18 is provided on the upper surface of the bottom wall.
At the same time, the rod-shaped plug 19 protruding from the front surface of the ring-shaped part is loosely inserted into the nozzle cylinder, and the rear face of the elastic frame 20 attached to the rear face of the ring-shaped part is brought into contact with the rear inner surface of the peripheral wall. Member with stopper 11
and an operating member 12 in which an elastically deformable hemispherical part 21 is stretched by closing the upper end opening surface of the peripheral wall, and a tapered rod 22 with a small diameter is suspended downward from the center of the lower surface of the hemispherical part. , a short cylindrical spout member 1 having a tapered spout 23 with a large rear diameter that is fitted into the front end opening of the nozzle tube and closes the front end of the rod-shaped plug;
3, by pressing the hemispherical part and pushing the lower end of the tapered rod down into the ring-shaped part, the ring-shaped part resists the elastic restoring force of the elastic frame by engaging with the tapered rod. It is characterized in that the front end of the rod-shaped plug can be pulled out from the tapered nozzle opening by moving rearward to open the nozzle opening.

"Operation" For example, in the state shown in FIG. 1, the front end of the rod-shaped stopper 19 is inserted into the tapered nozzle 23 and the nozzle is closed.

From the above state, the hemispherical portion 21 is pressed to push the lower end of the tapered rod 22 down into the ring portion 18. At this time, at the same time, the head body 10 is connected to the stem 2.
(See FIG. 1).

As a result, the front end of the rod-shaped stopper 19 is pulled out of the tapered nozzle 23 by the backward movement of the ring-shaped portion as described above, and the nozzle is opened.

As a result, the liquid inside the container discharged by pressing down the head body is transferred to the spiral tube 15 and the ring-shaped portion 18.
The water is ejected from the nozzle to the outside through the nozzle tube 17 (strictly speaking, the nozzle hole around the rod-shaped plug 19).

"Example" 1 and 2 show an embodiment of the present invention.

In the configuration shown in FIGS. 1 and 2, the ring-shaped portion 18 of the plugged member 11 is attached to the screw tube 1.
5, and is arranged slightly eccentrically toward the front with respect to the opening of the screw tube 15. The elastic frame 20 of the stoppered member is formed in a semicircular shape, and inside the head body 10, a protrusion 24 horizontally installed on the rear inner surface of the peripheral wall 16, a left side of the bottom wall 14,
It is positioned by projecting pieces 25, 25 erected on the upper surface of both right parts.

A communication groove 2 is provided in the front part of the tapered rod 22 of the operating member 12.
6 is installed vertically, and the tapered rod 22 is connected to the ring-shaped portion 18.
When the nozzle tube 15 is pressed down and fitted into the screw tube 15, the screw tube opening is prevented from being blocked, and communication between the screw tube and the nozzle tube 17 is ensured. Also,
The hemispherical portion 21 of the operating member is stretched over the upper end surface of the peripheral wall 16 via a tightening ring 27 . That is,
The hemispherical portion 2 is formed by the lower surface of an inward flange 29 attached to the upper inner edge of the tightening ring cylindrical wall 28 that fits on the upper outer surface of the head body peripheral wall 16 and the upper end surface of the peripheral wall.
This is to hold the lower peripheral edge of 1.

In the above embodiments, each part is molded and manufactured from synthetic resin material as appropriate.

"Effects of the invention" As explained above, according to the invention, the rod-shaped plug for opening and closing the spout is housed inside the head body, and
Since the opening/closing operation is linked to the vertical movement of the head body via the hemispherical part, unlike the conventional example where the spout is installed externally, the spout interferes with the ejected liquid and looks bad. There is no such thing, and
Like the conventional example where the spout is separated when the container is used,
There is no need to be careful about storing the spout when using the container.
Moreover, when opening and closing the rod-shaped stopper, it is only necessary to operate the hemispherical part, which is extremely convenient in terms of use and operation. Furthermore, the ring-shaped portion is configured to move backward against the elastic restoring force of the elastic frame due to engagement with the tapered rod, and the front end of the rod-shaped plug slips out of the tapered nozzle opening, thereby opening the nozzle. This also has the effect of making it possible to reliably open the nozzle.
