Description

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

"Problems to be Solved by Conventional Techniques and Inventions" A liquid ejector in which a vertical pump is mounted by a mounting cylinder fitted to the outer circumference of the neck of the container body is known. These are the nozzle holes of the push-down head that suck up the liquid inside the container by the suction pipe by vertically moving the push-down head at the upper end of the stem that protrudes upward and upward in the upper neck of the container body and is vertically movable. Although it is configured to squirt out more, the push-down head can be locked in a lowered state for storage or transportation to prevent unnecessary or accidental squirting of the content liquid. ing. As a specific example of such a configuration, conventionally, the above-mentioned stem is provided so as to project vertically from an engaging cylinder provided on the upper surface of the mounting cylinder, and the inner surface of the engaging cylinder and the upper end of the stem are screwed together. .

However, the screwing in the upward biased state may cause the screwing to be disengaged due to vibration or the like, and particularly in the case of this type of container, which is often formed of a highly flexible material such as a synthetic resin. The tendency is remarkable. In addition, it is troublesome for the user to remove the screw when using, and to use the screw again after using.

An object of the present invention is to provide a liquid ejector which eliminates the above-mentioned drawbacks of the prior art.

"Means for Solving the Problem" The mounting cylinder 4 detachably fitted to the outer periphery of the mouth / neck portion 2 of the container body 3.
As a result, the cylinder 6 at the lower end is hung down into the container body 3, and the push-down head 7 at the upper end is projected above the mouth / neck portion 2 so as to be movable upward and downward so that the vertical pump 5 is mounted. When the pressing head 7 is moved up and down, the liquid in the container body 3 is sucked up by the suction pipe 8 attached to the lower end of the cylinder 6 and is ejected from the nozzle hole 9 of the pressing head 7. In this liquid ejector, a leaf spring 12 capable of exerting an elastic force outward from the center is provided on the upper surface of the mounting cylinder 4, and an engaging projection 13 is provided on the depressing head 7 for depressing. When the head 7 is lowered, the engaging projections 13 are abutted and locked on the outer surface of the leaf spring 12 so that the push-down head 7 can be locked at the lowered position against the upward biasing force. And a liquid ejector.

[Operation] By vertically moving the push-down head 7 from the state shown in FIG. 1, the vertical pump 5 is actuated to suck up the liquid in the container body 3 from the lower end of the pipe 8 and the nozzle 9 of the suction head 7. Let

After use, if the pressing of the rear leaf spring 12 is released by lowering the pressing head 7 while pushing the tip of the leaf spring 12 rearward,
As shown in the drawing, the leaf spring 12 presses and locks the back surface of the engaging projection 13 of the push-down head 7 to lock the push-down head 7 in the lowered state. In use, if the tip of the leaf spring 12 is pushed backward, the pushing down head 7 is automatically raised by the upward biasing force and the state shown in the first figure is obtained.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention, in which 1 denotes a liquid ejector. The ejector 1 includes a container body 3 in which a mouth / neck portion 2 is erected, a mounting cylinder 4 detachably fitted to the outer periphery of the mouth / neck portion 3, and a vertical pump mounted and fixed to the container body 3 by the mounting cylinder 4. It is composed of 5 and.

In the vertical pump 5, the cylinder 6 at the lower end is hung down into the container body 3, and the pressing head 7 at the upper end is connected to the mouth / neck portion 2.
It is upwardly biased and vertically movably projected, and the liquid in the container body 3 is sucked up by the suction pipe 8 attached to the lower end of the cylinder 6 by vertically moving the pressing head 7. At the same time, it has a known pump mechanism configured to eject from the nozzle hole of the push-down head 7.

A cylindrical locking member 10 is fixed to the upper surface of the mounting cylinder 4, and a stem 11 is provided so as to vertically move from the center thereof. Further, an arc-shaped leaf spring 12 is provided on the front portion of the locking member 10.
Are integrally projected, and when the leaf spring 12 is pressed toward the center, elastic force can be exerted from the center toward the front. Further, when an engaging projection 13 is hung from the lower end of the front part of the push-down head 7 to lower the push-down head 7 against the upward biasing force, the engaging projection 13 is formed on the outer surface of the leaf spring 12. Is abutted and locked so that the push-down head 7 can be locked at the lowered position.

It should be noted that all of the above members may be made of synthetic resin.

"Effect of the Invention" As described above, the liquid ejector of the present invention has the above-described configuration. Therefore, the leaf spring 12 can be operated by pressing down the pressing head while pressing the leaf spring toward the center. The back surface of the engaging protrusion 13 can be pressed and locked to hold the press down head in a lowered state, and the pressing of the press head can be released only by pressing the leaf spring toward the center. Easy to handle. Further, the pressure locking by the leaf spring and the engaging projection is stronger against vibration than the conventional screwing, and the effect is more remarkable if the leaf spring and the engaging projection are formed in a shape that does not easily come off in the vertical direction. Becomes

Claims (1)

[Scope of utility model registration request] 1. A mounting cylinder 4 detachably fitted to the outer periphery of the mouth / neck portion 2 of a container body 3 causes a cylinder 6 at the lower end to hang down into the container body 3 and a push-down head 7 at the upper end to be attached to the mouth / neck portion 2. The vertical pump 5 is mounted so as to project upward so as to be movable upward and downward, and the liquid in the container body 3 is mounted on the lower end of the cylinder 6 by vertically moving the pressing head 7. In the liquid ejector configured to suck up from the lifting pipe 8 and eject from the nozzle hole 9 of the push-down head 7, the elastic force can be exerted on the upper surface of the mounting cylinder 4 outward from the center. A leaf spring 12 is provided, and an engaging projection 13 is provided on the push-down head 7. When the push-down head 7 is lowered, the engaging projection 13 abuts and engages with the outer surface of the leaf spring 12 to hold the push-down head. 7 can be locked in the lowered position against the upward biasing force Liquid ejector characterized by comprising form.
