Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a pump-type liquid ejection container.

``Problems to be solved by conventional techniques and inventions'' Conventionally, a pump type liquid ejecting container shown in Fig. 3 has been known as a container for taking out liquid or cream shampoo, conditioner, etc. from the container body. There is.

These include a spouting head 3 that protrudes from the container body 1 via a stem 2 so as to be able to move up and down in an upwardly biased state.
By pressing down, the liquid inside the container is ejected from the nozzle tube 4 protruding from the front surface of the ejection head 3.

However, in the conventional jetting container as described above, the nozzle hole was simply opened on the front end surface of the nozzle tube 4, so that the liquid remaining in the nozzle hole after using the container could dry and solidify, or the liquid inside the nozzle hole could get wet. There was a drawback that the nozzle hole could become clogged due to dust adhering to it.

The present invention prevents the remaining liquid in the nozzle hole from drying and solidifying, or dust from adhering to the nozzle hole, and enables smooth dispensing of liquid without clogging. The object of the present invention is to propose an excellent liquid ejection container that can be formed by changing the structure with a simple structure, and that is free from the risk of damage (separation of the covering) when liquid is poured out.

``Means for Solving the Problems'' In order to solve the above-mentioned problems, the container of the present invention squirts out the liquid inside the container by pushing down the spouting head 3 which is vertically movable and protrudes upwardly biased from the container body 1. Nozzle tube 4 protruding from the front of the head
In a liquid ejecting container that is installed to eject a liquid, the front end surface of the nozzle cylinder 4 is closed to open the nozzle hole 5 in a portion of the cylinder wall 4a near the front end of the nozzle cylinder, and the opening 5a is closed to open the nozzle. A rubber cylindrical covering 6 is tightly fitted onto the outer surface of the cylinder 4, and when the liquid in the nozzle cylinder is pressurized, the cylinder wall portion of the covering that closes the opening is pushed and expanded by the pressurized liquid. A discharge passage communicating between the opening 5a and the tip opening 7a of the covering can be formed between the outer surface of the cylindrical wall 4a of the nozzle and the inner surface of the cylindrical wall 6a of the covering.

"Function" For example, in the state shown in FIG. 1, the nozzle hole opening 5a of the nozzle tube 4 is closed by the inner surface of the tube wall 6a of the covering 6, so the nozzle tube 4 is closed after the container is used.
This prevents the liquid remaining in the nozzle hole 5 from drying and solidifying, and also prevents dust from adhering to the inside of the nozzle hole 5.

When using the container, it is sufficient to press down the spouting head 3 from the above-mentioned state as before. As a result, the pressurized liquid in the nozzle cylinder 4 causes the nozzle hole opening 5a to
The cylindrical wall 6a of the sheathing body 6 that closes the area is pushed out against the elastic restoring force, and a discharge path to the outside is formed between the nozzle tube and the sheath. Liquid is spouted well.

In addition, at this time, the front end surface of the nozzle tube 4 is closed, and the nozzle hole 5 is opened in the portion of the tube wall 4a near the front end of the nozzle tube. , that is, in a direction perpendicular to the direction in which the sheath comes off, and prevents the sheath from coming off from the nozzle.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention. The container of the present invention is constructed by pushing down the ejection head 3 which is vertically movable and protrudes from the container body 1 in an upwardly biased state. It has a known pump mechanism provided so that liquid is ejected from a nozzle tube 4 protruding from the front surface of the ejection head.

The nozzle tube 4 is formed separately from the ejection head 3,
The rear end portion is irremovably fitted into a fitting hole 8 on the front surface of the ejection head 3 via an engaging means 9 having a concave and convex strip. Further, the front end of the nozzle tube 4 is closed with a reduced diameter in the shape of a mountain in plan view, and a single nozzle hole 5 is formed in the lower part of the cylinder wall 4a located slightly behind the mountain-shaped portion 10. It is opened as part 5a.

In addition, the cylindrical covering body 6 whose front end portion is bent into an F-shape is fitted at the rear end of the nozzle cylinder 4 in a water-tight manner and cannot be pulled out through the engagement means 11 having uneven stripes. , the front end is located in front of the nozzle hole opening 5a and below the mountain-shaped portion 10 and is suspended, and the front end surface thereof is opened as a single opening (spout) 7a of the covering hole 7. Further, a portion of the cylindrical wall 6a of the covering body that closes the nozzle hole opening 5a is formed thinner than other portions.

In addition, 12 in the figure is a screw tube installed vertically from the bottom surface of the spouting head 3, and when not in use, the screwed member 13 on the side of the container body 1
The spouting head 3 is fixedly held by being screwed into the spouting head 3.

"Effects of the invention" As explained above, according to the invention, the opening of the nozzle tube is closed with a rubber cylindrical covering, so that
It is possible to prevent the remaining liquid in the nozzle hole from drying and solidifying, and to prevent dust from adhering to the nozzle hole, and enables smooth pouring of liquid without clogging.

In addition, since the tip of the nozzle tube is closed and the opening is opened in the tube wall near the front end of the nozzle tube, the liquid pressure is applied to the fitting surface of the nozzle tube and the covering in the vertical direction, that is, the covering is It hangs in the direction perpendicular to the direction in which it comes out, so there is no risk that the covering will come off due to hydraulic pressure.

Furthermore, the structure of the nozzle tube and the covering part is extremely simple and can be obtained by changing only a small part of the structure of conventional containers of this type, so manufacturing costs can be extremely low and various other effects can be obtained. It is something.
