Description

[Detailed description of the invention] The present invention relates to a sprayer for spraying mist, foam, etc., and is designed to prevent liquid leakage during transportation.

Conventionally, vertical reciprocating pump-type mist sprayers have been widely used.

The ejector has a suction valve at the bottom of a cylinder that hangs down from the inner surface of a mounting member attached to the mouth of the container, and has a cylindrical piston fitted into the cylinder or a mounting member fitted with the piston at its base end. There is a discharge valve in the stem that penetrates the stem, and when the jet head with a nozzle fitted on the upper end of the stem is pushed down, the discharge valve opens and the liquid in the cylinder is jetted out, and when the jet head is released, the head It is configured to rise and at this time suck the liquid inside the container into the cylinder.

By the way, the suction and discharge valves normally use ball valves, so when the injector falls over, the ball valve will separate from the valve seat due to its own weight, and the suction and discharge valves will lose their functions. , which caused liquid leakage.

In this case, the base end surface of the nozzle hole is blocked by the upper end wall surface of the stem during transportation to prevent the liquid from leaking, and the stem hole and nozzle hole can easily communicate with each other during use by consumers. This is what I did.

Referring to the drawings below, reference numeral 1 denotes a mounting member in which a peripheral wall 3 is vertically disposed from the periphery of a top wall 2 having an insertion hole in the center thereof to be fitted onto the outer surface of the mouth and neck of the container body.

Reference numeral 4 denotes a cylinder, which is vertically installed with a large diameter portion 5 attached to its upper end fitted into the upper inner surface of the peripheral wall of the mounting member.

The cylinder has a suction valve 6 made of an elastic plate at the bottom, and a suction pipe 7 is vertically disposed in communication with the suction valve hole.

A cylindrical piston 8 is fitted into the cylinder so as to be movable up and down, and the piston is fitted onto the lower end of a stem 9 which is movable up and down through an insertion hole in the top wall of the mounting member.

A jetting head 11 with a nozzle 10 is fitted to the upper end of the stem.

A discharge valve 12 is provided within the cylindrical piston or stem.

Inside the cylinder is a coil spring 1 that urges upward an operating member formed by a cylindrical piston, a stem, and an ejection head.
3 are installed inside.

In the above conventional structure, in the present invention, a discharge hole 9a that can communicate with the nozzle hole 10a is bored at a lower position (beyond the upper end of the stem), and the jet head 11 can be freely attached to and detached from the stem. An outer tube 14 shorter than the stem is fitted onto the outer surface of the stem.

The outer tube is attached to the ejection head 11 as shown in the figure.
When fitted, a part of the ejection head comes into contact with the upper end of the outer tube, making deep fitting to the stem impossible and resulting in a shallow fitting. As a result, the discharge hole 9a and nozzle hole 10a are misaligned, and the nozzle The base end surface of the hole can be closed watertight by the stem portion above the discharge hole.

In order to communicate the ejection hole and the nozzle hole, the ejection head is removed, the outer tube 14 is removed, and the ejection head 11 is fitted deeply again to align the ejection hole and the nozzle hole.

The present invention has the above-mentioned configuration, and if the ejection head is fitted to the upper end of the stem with the outer pipe fitted to the stem, the base end surface of the nozzle hole is closed by the upper end portion of the stem.
It is possible to reliably prevent liquid leakage during transportation, etc., and when the consumer wants to use it, he or she can simply remove the outer tube and fit the ejection head deeply into the upper end of the stem, making it ready for use. It is also extremely easy to do so, and since it is only necessary to provide a discharge hole in the upper part of the stem and fit the outer tube to the stem, the cost of doing this is extremely low.

Claims (1)

[Scope of utility model registration request] A cylinder 4 is suspended from the upper inner surface of the mounting member 1, which is provided so as to fit into the mouth of the container body, and a cylindrical cylinder 4 attached to the lower end of the stem 9 passes through the top wall of the mounting member. A piston 8 is fitted, a jet head 11 with a nozzle is attached to the upper end of the stem, a suction pipe is vertically installed at the bottom of the cylinder via a suction valve 6, and a discharge pipe is installed inside the stem or cylindrical piston. In a mist sprayer equipped with a valve 12,
A discharge hole 9a communicating with the nozzle hole is formed below the upper end of the stem, and the jet head is detachably attached to the stem, and an outer tube 14 shorter than the stem is provided on the outer surface of the stem. If the jetting head is fitted to the stem while the outer tube is fitted, a portion of the jetting head will come into contact with the upper end of the outer tube and the fit will be shallow, resulting in misalignment between the discharge hole of the stem and the nozzle hole, and the nozzle hole A mist ejector whose base end surface can be closed watertightly by a stem portion above a discharge hole and which is removably fitted.
