Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a vertical pump type liquid ejection container for ejecting a liquid in the form of liquid, mist, foam or the like.

"Prior Art" From inside of a cylinder mounted on a container body, an operating member having a push-down head with a nozzle attached to the upper end of the standing cylinder is protruded upward, and the liquid inside the container is moved to the cylinder by vertically moving the operating member with respect to the container body. The liquid ejector provided so as to suck the liquid in the cylinder and eject the liquid in the cylinder from the nozzle through the inside of the operating member is an obstacle for the operating member during transportation, and is bulky during packaging. Press down against the bias,
It is known that the upper end of the standing cylinder is screwed into a female screw cylinder attached to the upper end of the cylinder.

"Problems to be solved by the invention" In the conventional liquid ejection container in which the upper part of the standing cylinder is screwed to the upper end of the cylinder by pushing down the operating member against the bias, the operating member is moved upward by removing the screwing. In the state of being pushed up to, a gap corresponding to a male screw is formed between the inner surface of the female screw portion at the upper end of the cylinder and the standing cylinder. Therefore, when the liquid jetting container is used in a place where water or hot water is easily scattered, such as a bathroom, water or the like enters the gap, and the gap is prevented from negative pressure due to the liquid in the container decreasing due to the liquid jetting. For forming the inlet of the outside air supply passage for the above, the water enters the container body through the outside air supply passage,
Then, there is a drawback that it mixes with the liquid in the container to make the liquid cloudy.

The present invention aims to eliminate such defects.

“Problems to be solved by the invention” The outward flange 4 attached to the upper part of the cylinder is attached to the container body 1.
The cylinder 5 is hung vertically inside the container body 1 by sandwiching it between the top surface of the mouth and the inward flange 7 at the upper end of the mounting cylinder 6 fitted in the mouth neck portion 2 of the container body, and the cylinder 5 is provided with a nozzle. The upright cylinder 10 of the actuating member 13 which attaches the push-down head 12 to the upper end is pushed down against the urging force, and in the depressed state, is inserted into the female screw cylinder 15 attached to the upper end of the cylinder 5 to the outer surface of the upper end of the upright barrel 10. In the liquid ejection container in which the provided male screw portion 16 is screwed, the long cylinder 18 is fitted to the outer surface of the standing cylinder portion below the male screw portion 16, and the operating member for the cylinder 5 for ejecting the liquid to the outer surface of the long cylinder. Elastic ridges that are always watertight within the stroke range of 13
19 is provided around the inner surface of the lower end portion of the female screw cylinder 15, and an outside air supply passage 17 is formed in the standing cylinder 10 to connect the inside of the cylinder and the outside of the long cylinder through the inner surface of the long cylinder and the upper and lower ends. .

[Operation] As shown in FIG. 1, when the operating member 13 is in the lowered state, the male screw portion 16 and the female screw cylinder 15 are screwed together, so there is no risk of water entering the container body through the gap. As shown in FIG. 2, when the male threaded portion 16 is unscrewed from the female threaded cylinder 15 and the actuating member 13 is raised by urging, the elastic ridges 19 circumferentially provided on the inner surface of the lower end of the female threaded cylinder 15 are attached to the outer surface of the standing cylinder. Since it is watertightly contacted with the outer surface of the fitted long cylinder 18, even if water or the like enters the inner surface of the female screw cylinder, there is no possibility that the water will further pass through the cylinder 5 and enter the container.
The replacement outside air for preventing negative pressure in the container is supplied to the inside of the container through the outside air supply passages 17 provided on the inner surface of the long cylinder 18 and through the through holes 5a formed in the upper part of the cylinder.

"Example" 1 is a container body which erects a mouth / neck portion 2, and an outward flange 4 at the upper part of the cylinder is placed on the top surface of the mouth thereof via a packing 3 so that the cylinder 5 is placed by the placement. It is hung inside the container.

A mounting cylinder 6 is screwed onto the outer surface of the mouth / neck portion 2, and an outer flange 4 of the cylinder is sandwiched between the inward flange 7 at the upper end of the mounting cylinder and the top surface of the container body mouth. A suction valve 8 is provided at the bottom of the cylinder, and a suction pipe 9 is hung from the suction valve to the bottom of the container body.

The upright cylinder of the actuating member 13 having the pushdown head 12 with the nozzle 11 attached to the upper end of the upright cylinder 10 is pushed into the cylinder 5 against the upward bias of the spring 14. In order to maintain the pushed state, an inner and outer cylinder is hung from the inner and outer peripheral edges of the collar-shaped top wall at the upper end of the cylinder 5, and a female screw cylinder 15 having an inner thread on the inner cylinder is fitted and the female screw cylinder. A male screw portion 16 formed on the outer surface of the upper end of the standing cylinder 10 of the actuating member 13 is screwed onto the. A portion below the male screw portion 16 of the standing tube is fitted with a small outer diameter portion, and a long cylinder 18 having a groove as an outside air supply passage 17 on the inner surface and both upper and lower surfaces is fitted into the smaller outer diameter portion. An elastic protrusion 19 is provided around the inner surface of the lower end of the female screw cylinder 15. As shown in FIG. 2, the elastic ridge is a cylinder in which the internal threaded cylinder 16 and the externally threaded portion 16 are unscrewed and the actuating member 13 is lifted by the urging of the spring 14, and the liquid is ejected. 5 is provided so as to be watertightly in contact with the outer surface of the long cylinder 18 within the range of the stroke for vertically moving the operating member.

A discharge valve 20 is provided in the upper end portion of the standing cylinder 10, and the standing cylinder portion has a cylindrical piston 21 at the lower end. With the operating member at the upper limit, the cylindrical piston closes the through hole 5a formed in the upper part of the cylinder as the lower end of the outside air supply passage 17. A guide member 22 is installed inside the cylinder, and a cylindrical piston 21 moves up and down along the outer surface of the upper portion of the member. The upper limit of the operating member 13 is determined by the outward flange 13a attached to the lower part of the standing cylinder above the cylindrical piston and contacting the lower end surface of the female screw cylinder 15.

"Effect of the device" As described above, the present invention is a long cylinder within the range of the operating member stroke.
18 Since the elastic ridge 19 at the lower end of the female screw cylinder is provided so as to be in watertight contact with the outer surface, even if water is stored between the female screw and the long cylinder 18, the water will enter the container and cloud the liquid inside the container. Further, since the outside air supply passage 17 is formed so as to pass through the inner surface of the long cylinder and the upper and lower ends, water and the like will not enter the container body through the outside air supply passage.
