Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application" The present invention relates to a manual liquid ejector.

"Prior Art" As a conventional manual liquid ejector, for example, the actual Kai 61-14
The invention of Japanese Patent No. 3663 is known. In this ejector, a vertical pump mechanism is installed in the container body by a mounting cylinder fitted in the neck portion of the container body, and a head is fitted to the upper end of the stem rising from the vertical pump mechanism. Further, a nozzle tube is provided on the front surface of the head so as to communicate with the stem, and a spring is provided in the vertical pump mechanism to urge the head upward through the stem. With this configuration, when the head is pushed down, the liquid in the vertical pump mechanism is ejected from the nozzle tube, and when the push is released, the head is returned by the spring and the container liquid is sucked up into the vertical pump mechanism. is there.

[Problems to be Solved by the Invention] Since the above conventional liquid ejector has a structure in which a spring is incorporated in the vertical pump mechanism, a force is required to depress the head against the bias of the spring, and Since the structure is complicated and assembly is troublesome, and the head is constantly pushed up when the ejector is not used due to the biasing of the spring, the head part is bulky during transportation, and the head is dropped due to things falling onto the top surface of the head. There was a risk that the liquid would be ejected by the descent and stain the neighborhood.

Furthermore, since the front of the nozzle hole is always open, the liquid remaining in the nozzle hole is likely to dry, and the dried product may clog the nozzle hole.

The present invention is intended to solve the above conventional problems.

[Means for Solving the Problem] The vertical pump mechanism 7 is housed in the container body by the mounting cylinder 3 fitted in the mouth neck 2 of the container body, and a part of the pump mechanism is formed to form the upper part of the mounting cylinder. A head 13 is fitted on the upper end of the stem 12 that stands upright, and the stem liquid is moved up and down with respect to the container body through the head so that the container liquid can be ejected from a nozzle hole opening on the front surface of the head. In the liquid ejector described above, the left and right side surfaces of the head 13 can be freely undulated by bending both ends of the curved strip plate 17 covering the front of the nozzle hole and the outer surface of the front half circumference of the head 13 at the time of fall. When the curved strip-shaped plate is erected, the finger-inserted space can be formed between the upper surface of the head 13 and the top of the curved strip-shaped plate.

"Action" For convenience of explanation, the manual liquid ejector has already been used several times.
Vertical pump mechanism 7 is moved up and down in the state shown in FIG.
The inside shall be filled with liquid.

To eject the liquid from the state shown in FIG. 1, the curved strip plate 17 is first pulled up. Then, as shown in FIG. 2, the front of the nozzle hole 15 is opened and a finger insertion space is formed between the upper surface of the head 13 and the top of the curved strip plate 17, so that a finger can be inserted into the space. And, hold the body of the container with your other fingers. When the inserted finger is lifted in this state, the head 13 is lifted via the curved strip 17 as shown in FIG.
The vertical pump mechanism 7 operates to suck the liquid in the container body 1 into the inside thereof. When the finger inserted in the joint is lowered, the head 13 is lowered, and the vertical pump mechanism operates to eject the internal liquid from the nozzle hole 15.

After using the ejector, the head 13 is lowered and the curved back plate
17 is laid down and returned to the state shown in FIG.

[Example] The present invention comprises a container body, a mounting cylinder, a vertical pump mechanism, a head, and a curved strip plate.

Reference numeral 1 denotes a container body which stands up the mouth / neck portion 2, and the inner peripheral surface of the lower half portion of the mounting cylinder 3 is screwed onto the outer surface of the mouth / neck portion.

The mounting cylinder 3 has an inward flange 4 at the upper end of its inner peripheral surface.
And a peripheral groove 5 is formed by opening the upper end peripheral surface of the mounting cylinder 3. In addition, it is advisable to laterally install the engaging projection 6 on the upper front surface of the mounting cylinder 3.

A vertical pump mechanism 7 is incorporated in the container body 1. In the vertical pump mechanism, an outward flange 9 attached to an upper portion of a cylinder 8 which is a main part of the vertical pump mechanism is sandwiched between an upper end surface of a container body neck 2 and an inward flange 4 lower surface of a mounting cylinder to form a container body 1.
Fixed inside. The cylinder 8 has a suction pipe 10 suspended from a suction valve provided in the lower end thereof, and a head locking cylinder 11 described later is fitted to the upper end of the cylinder. The vertical pump mechanism 7 has a cylindrical piston slidably fitted in the cylinder 8 and a discharge valve in a stem 12 which is erected by fitting a lower end portion of the cylindrical piston upper small diameter portion. It will be provided.

A head 13 is fitted on the upper end of the stem 12. The head has a stem fitting tube 14 fitted to the stem 12 hanging from the center of the lower surface thereof and is inserted into the stem to form a nozzle hole 15 in the front surface of the head 13, and further from the outer edge of the lower surface of the head. A sliding cylinder 16 is hung so as to be vertically movable in the peripheral groove 5 of the mounting cylinder.

In the liquid ejector having the structure described above, when the stem 12 is moved up and down with respect to the container body 1 via the head 13, the vertical pump mechanism 7 operates to eject the liquid in the container body 1 from the nozzle hole 15.

A curved band plate 17 is attached to the head 13. The curved strip plate is formed by pivoting both ends of the curved strip plate on the left and right side surfaces of the head 13 so that the curved strip plate can be raised and lowered freely. A space for inserting a finger is provided between the head rise and the top of the curved strip plate 17 when standing up. It is desirable to provide a knob 18 for pulling up on the curved strip plate 17 so as to project from the front surface of the lower end thereof in the fall state, and from the lower surface of the knob, the engaging projection of the mounting cylinder at the lower limit position of the head 13. It is preferable that the hook 19 that engages with 6 be hung.

[Advantage of the Invention] Since the present invention has the above-described configuration, it is not necessary to incorporate a spring in the vertical pump mechanism 7, and therefore the head 13 does not have to be pushed down against the bias of the spring. The head is lightly pushed down, and its structure is simple and easy to assemble.
Further, when the ejector is not used, the head is urged upward by the spring.
Since 13 does not always be pushed up, the head portion does not become bulky when carrying the ejector, and even if an object is dropped onto the upper surface of the head, the head is pushed down and liquid is ejected. There is no danger of

Further, in the present invention, since the curved belt-shaped plate 17 of the head is provided so that the nozzle hole 15 covers the front side when the head falls down, the liquid remaining in the nozzle hole does not easily dry, and therefore the nozzle hole formed by the dried product is used. Less risk of clogging.
