Description

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

"Prior Art" From a cylinder mounted on a container body, an operating member having a push-down head fitted with a nozzle fitted to the upper end of the stem is projected upwardly, and the liquid inside the container is moved to the cylinder by the vertical movement of the operating member relative to the container body. The liquid ejector, which is provided so as to suck the liquid in the cylinder and eject the liquid in the cylinder from the nozzle of the actuating member, prevents the actuating member from being urged because the actuating member obstructs during transportation and the packaging becomes bulky. It is known that the upper part of the operating member is detachably screwed to the inner surface of the holding cylinder attached to the upper end of the cylinder.

"Problems to be solved by the invention" A conventional pump-type liquid ejection container in which an operating member is pushed down against an urging force and its upper part is screwed into a holding cylinder attached to the upper end of a cylinder is When the cylinder is mounted and the cylinder is mounted, it is erected upward above the container body, and a gap for screwing the male screw on the upper part of the operating member is formed between the inner surface of the holding cylinder on the upper end of the cylinder and the lower part of the stem of the operating member. Will be done. Therefore, when the liquid jetting container is used in a place where water, hot water, or the like is easily scattered, such as a bathroom, water or the like attached to the upper surface of the holding cylinder having the female screw hole or the stem enters the space for male screw screwing, Further, since the gap forms an inlet of the outside air supply passage for preventing negative pressure due to liquid decrease in the inside of the container due to liquid ejection, the water enters the inside of the container through the outside air supply passage, There is a drawback that when mixed with a liquid, the liquid becomes cloudy.

The purpose of the present invention is to prevent the liquid in the container from becoming cloudy due to the inflow of water into the container.

[Means for Solving the Problem] The outward flange 4 attached to the upper part of the cylinder is attached to the container body 1.
The cylinder 5 is vertically suspended in the container body 1 by being sandwiched between the mouth top surface and the inward flange 7 at the upper end of the mounting cylinder 6 fitted in the mouth neck 2 of the container body, and the nozzle is provided at the upper end of the cylinder 5. The stem 11 of the operating member 10 to which the push-down head 14 is fitted is pushed down against the bias, and the upper portion of the operating member and the holding cylinder 20 attached to the upper end of the cylinder are detachably screwed in the pushed state. In the liquid jetting container thus prepared, the outer surface of the holding cylinder 20 is attached with a male screw 23.
Formed on the male screw, the female screw cylinder 17 hanging from the lower surface of the push-down head 14 is screwed into the male screw, and the upper end inner surface of the elastic cylinder is protruded from the upper end of the holding cylinder 20 by projecting the reverse skirt-shaped elastic cylinder 24 of the upper small diameter upward. The gap width due to the diameter difference between the outer surface of the stem 11 and the outer surface of the stem 11 was determined to be watertight and allow air to flow.

[Operation] As shown in FIG. 1, the operating member 10 is pushed down with respect to the container body 1, and the female screw cylinder 17 is hung from the lower surface of the pressing head 14 to the outer surface of the male screw 23 of the holding cylinder 20 fitted to the upper end of the cylinder. In the state where they are screwed together, the stem 11
Also, water droplets and the like do not adhere to the elastic cylinder 24 and the like. Also, as shown in FIG. 2, when the actuating member 13 is raised and when it is moved up and down, the upper end of the elastic cylinder 24 in the shape of a reverse skirt protruding from the upper end of the holding cylinder is watertight but airtight to the outer surface of the lower portion of the stem 11. The inner surface of the holding cylinder 20 and the stem 10
Water, etc., will not enter the container body through the space between.

"Example" 1 is a container body in which a mouth / neck part 2 is erected, and an outward flange 4 on the upper part of a cylinder is placed on the top surface of the mouth through a packing 3 and the cylinder 5 is placed in a container by the placement. It is hung inside the body.

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 an 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.

An operating member 10 is fitted in the cylinder 5. The actuating member has a cylindrical piston 12 fitted on the lower end of the stem 11, and a fitting cylinder 15 hanging from the lower surface of a pressing head 14 with a nozzle 13 fitted on the outer surface of the stem with a small outer diameter part. The discharge valve 16 is provided in the upper end of the stem. The fitting cylinder has a large outer diameter portion 15a only at its upper end, and the outer diameter of the lower part thereof is the same as the outer diameter of the stem portion below the fitting cylinder in order to have a function as a stem. Further, a female screw cylinder 17 is hung from the lower surface of the push-down head 14 with a gap between the fitting cylinder 15 and the outer surface thereof.

A guide rod 18 standing upright from the bottom of the cylinder is provided inside the cylinder 5, and the operating member 10 moves up and down relative to the guide rod and the cylinder with the guide rod inserted in the stem thereof. Is provided. Reference numeral 19 is a spring for urging the operating member upward.

The holding cylinder 20 is fitted on the upper end of the cylinder, and the stem 11 is inserted through the holding cylinder. The holding cylinder (20) has an inner cylinder (21) and an outer cylinder (22) hanging from both the inner and outer peripheral edges of the collar-shaped top wall, and the outer cylinder is fitted to the outer surface of the cylinder upper end portion, and the inner cylinder is extended upward to extend the extension. The lower half of the part is a male screw 23, and the upper half of the extension is an inverted skirt-shaped elastic cylinder 24 having a small upper diameter. As shown in FIG. 1, when the actuating member 10 is held in the lowered state, The female screw cylinder 17 is screwed onto the male screw 23. In this state, the upper end of the elastic cylinder 24 is raised to the outer surface of the large outer diameter portion of the upper part of the screw cylinder 15.

By rotating the push-down head 14 with respect to the holding cylinder 20 and unscrewing the female screw cylinder 17 from the male screw 23, the spring 19 pushes up the operating member 10 as shown in FIG. By moving the liquid, the liquid in the container is ejected from the nozzle 13. When the operating member moves up and down, and when the operating member is located at the upper limit as shown in FIG. A space is formed between and to allow the passage of air and the passage of air. In forming the gap, the large outer diameter portion 15a at the upper end of the fitting cylinder 15 is set to have an appropriate outer diameter, the upper end of the elastic cylinder 24 is raised onto the outer surface, and the lifted state is the operation of FIG. This can be easily performed by providing the member in a lowered state so that it is maintained for a long time. The gap forms the upper end of the outside air supply path to the inside of the container body 1, and the inside of the container body 1 is passed from the outside air supply hole 5a formed in the cylinder upper part through the space between the stem 11 and the holding cylinder 20 and the upper part of the cylinder 5. The outside air is supplied to the inside of the container, and the outside air corresponding to the amount of the liquid reduced by the jet of the liquid enters the inside of the container to prevent the negative pressure. The outside air supply hole is closed by the cylindrical piston 12 when the operating member is raised, and the outside air is supplied only when the cylindrical piston moves below the outside air supply hole 5a.

"Effect of the device" The present invention is configured as described above, and the outer surface of the holding cylinder 20 attached to the upper end of the cylinder is used as the male screw 23, and the male screw is pushed down from the lower surface of the pressing head 14, and the female screw barrel 17 is screwed. From the upper end of the holding cylinder (20), a small reverse diameter skirt-shaped elastic cylinder (24) is projected upward, and the gap width due to the diameter difference between the outer surface of the stem (11) inserted in the elastic cylinder and the inner surface of the elastic cylinder upper end is watertight and Actuating member 10
Despite being a liquid ejection container provided so that the upper part of the operating member and the holding cylinder 20 are detachably screwed together, water or the like adhering to the outer surface of the stem 11 or the like during use may cause the outside air supply passage to flow. There is no possibility that the liquid inside the container will become cloudy.
