Description

[Detailed description of the invention] In this invention, an operating pipe that also serves as a discharge pipe of the pump, which is housed inside the container body, penetrates the top wall of the cap that is fitted into the mouth of the container body and projects upwardly so as to be movable up and down. , relates to a sprayer for ejecting mist or foam, etc., in which a push-down head 5 with a nozzle is fitted at the tip of the operating tube.

Many types of ejectors are known, but they have the disadvantage of being almost uniform in appearance and lacking in variety.

The present invention eliminates such drawbacks, allows comfortable use of the ejector, and also provides a biasing effect to raise the push-down head.

To explain the drawings below, 1 is a container body, 2
is a cap fitted to the mouth of the container body. A known pump for sucking up the liquid inside the container is installed inside the container, and an operating pipe 3 that also serves as a discharge pipe has a cylindrical piston attached to the lower end of the pump.
It penetrates the top wall of the cap and projects upwardly so as to be movable up and down, and a push-down head 5 with a nozzle 4 is fitted into the upper end of the operating tube. The above structure may be of a known type, but the upper part of the cap has a small outer diameter part 2a.
It is preferable that the push-down head has an actuating tube fitting cylinder 5a hanging from the bottom surface.

In the above-mentioned foam ejector, in the present invention, a bellows tube 7 with fitting tubes 6, 6 attached to both upper and lower ends is provided between the cap 2 and the push-down head, and the actuating tube is loosely inserted into the bellows tube. Then, the fitting tubes 6, 6 were airtightly fitted into the cap and the push-down head, respectively. The bellows tube has a whistle port 8 in its part that generates sound by intake or exhaust air by expanding and contracting the bellows part.
shall be provided. The whistle may or may not have a vibrating tongue, or it may be equipped with a small whistle. The bellows tube may be integrally molded from an appropriate synthetic resin material, and is preferably formed by being biased in the direction of extension in the shape of a compression coil spring.

The present invention has the above-mentioned structure, in which the fitting tubes attached to the upper and lower ends of the bellows tube are fitted into the cap and the push-down head in a watertight manner, and the actuating tube is inserted loosely into the bellows tube. Because the whistle 8 was drilled in some parts,
When operating the push-down head for spouting mist, foam, etc., a sound is emitted, making it possible to perform the jetting operation comfortably, and since the actuating tube is loosely inserted into the bellows tube. The actuating tube acts as a guide and the bellows tube can be expanded and contracted in the vertical direction, making it easy to expand and contract.Also, because of the bellows tube, the appearance is different from conventional ejectors of this type. In addition, the bellows tube is expandable and can be easily formed by being biased in the direction of extension, so by using the bellows tube made in this way, the conventional It is also possible to use the spring used in this type of ejector for pushing up the operating tube.

The drawing is a partially cutaway side view of the mist, foam, etc. ejector according to the present invention. 1... Container body, 5... Push down head, 7... Bellows tube, 8... Whistle mouth.

Claims (1)

[Scope of utility model registration request] A discharge and operating pipe 3 of the pump housed inside the container body 1 is made to protrude upwardly so as to be movable up and down by passing through the top wall of the cap 2 fitted to the mouth of the container body, and a nozzle is provided at the tip of the operating pipe. In a mist, foam, etc. sprayer fitted with a push-down head 5, a bellows tube 7 with fitting tubes 6, 6 attached to both upper and lower ends is inserted between the cap and the push-down head into the bellows tube. The actuating pipe is loosely inserted into the cap, and the fitting cylinders 6, 6 are airtightly fitted and attached to the cap and the push-down head, respectively, and a part of the bellows pipe is attached to the top and bottom of the bellows to prevent the vertical movement of the push-down head. A fog characterized by being attached with a whistle 8 that emits sound by intake or exhaust air by expanding and contracting the bellows part,
Foam ejector.
