Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an ejector with a trigger for spraying or the like.

[0002]

2. Description of the Related Art Conventionally, in this type of ejector, the ejector body comprising a vertical reciprocating pump having a downward ejection head is mounted on the mouth and neck of the container body, and the rear part of the ejector body is provided. The boss is erected from the boss, and the hem-shaped trigger with the tip protruding forward is pivotally attached to the boss at the rear end. There is an ejector with a trigger in which the nozzle of the head is loosely inserted (Japanese Utility Model Publication No. 63-69579). In this case, the push-down operation of the push-down jet head can be made light and easy by the lever action of the trigger.

[0003]

However, in general, in a state where the container body is filled with a required liquid, the product is repeatedly circulated in the product distribution process.
Unexpected external force may be applied to the trigger to cause the contents to flow out, or the contents may be reduced below a certain amount due to the trigger being operated unintentionally in a store display, etc., which may lower the commercial value. . Moreover, if such a defective product is sold without noticing, it will not only be a disadvantage to the purchaser, but also cause dissatisfaction and anxiety to the purchaser, the manufacturer, and the seller. It will hurt the trust of the person. The present invention solves these problems and, in addition,
It is an object of the present invention to facilitate handling, provide a simple structure and manufacture, and can be provided at low cost.

[0004]

In order to achieve the above object, the invention of claim 1 relates to a main body of an ejector comprising a vertical reciprocating pump 21 having a push-down ejection head 22 at a mouth / neck portion 11 of a container body 1. Two

Because of the above structure, in any of the inventions, if the stopper 6 is rotated to engage the tip of the stopper with the upper surface of the side wall 21 of the exterior cover 3 and abut against each other, the trigger 4 is moved. The rotation is blocked, the ejector main body 2 does not work, and the content filled in the container body 1 does not leak out. When the stopper 6 is rotated in the reverse direction to disengage the tip from the above engagement, the trigger 4 becomes free, and the push-down jet head 22 is pushed down by operating the trigger, and the jet body 2 is operated. As a result, the content filled in the container body 1 is ejected from the push-down ejection head 22 to the outside through the ejection window 43. Further, the exterior cover 3 and the trigger 4 protect the ejector main body 2, that is, the push-down ejection head 22 and the vertical reciprocating pump 21 from external force, and reduce intrusion of dust and the like.

Further, according to the second aspect of the invention, the exterior cover 3 fitted and erected from the shoulder portion of the container body 1 ensures ease of assembly and stability, and has a laterally elongated knob-like stopper. 6 facilitates horizontal rotation, and the positioning engaging means 7 provided between the lower surface of the stopper 6 and an appropriate position on the upper surface of the rear portion of the trigger 4 secures the engagement and disengagement positions, and unexpectedly. Eliminate the rotation of.

According to the third aspect of the invention, the contents display means of the stopper 6 is provided for the liquid filled in the container body 1 according to the coloring, the description of characters and symbols, and the like.
For example, the types such as stain removal and mold removal are clearly indicated.
