Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an atomizer or a liquid ejector for ejecting liquid as it is without atomizing it.

``Prior art'' As a liquid ejector, a cylindrical piston is fitted in a cylinder vertically disposed within a container body so as to be able to move up and down, and a head with a nozzle is fitted to the upper end of a stem rising from the piston. It is known that an actuating member is provided in an upwardly biased state, and liquid within the container is ejected from a nozzle by vertical movement of the actuating member.

In this type of liquid ejector, the operating member is biased upward relative to the cylinder, and therefore the liquid ejector has the disadvantage of being large when packaged.
As shown in the figure, a threaded tube is fixed to the upper end of the cylinder, a stem is inserted into the threaded tube, and the connection between the upper end of the stem and the head is screwed into the threaded tube to maintain the operating member in a depressed state, so that transportation, etc. can be performed in this depressed state.

``Problems to be solved by the invention'' By fixing a screw tube to the inner surface of the upper end of the cylinder, inserting the stem into the screw tube, and screwing the connection part between the stem and the head into the screw tube, the cylinder On the other hand, a mechanism for holding the actuating member in a lowered state is convenient in that the liquid ejector can be made smaller during transportation, but a problem also arises in this case. That is, the liquid ejector and the container body to which the liquid ejector is attached are sent from the manufacturer to the storage liquid manufacturer, and the container body is filled with liquid, and the outer surface of the container body is coated with a label, etc. After pasting, it is sold commercially, but since the cylinder, the member for attaching the cylinder to the container body, and the screw tube are integrally connected, it is difficult to attach the liquid ejector to the container body. In this situation, the direction in which the nozzle protrudes and the above-mentioned reticle tend to be misaligned.

The present invention is designed to prevent such misalignment and to facilitate attachment of the liquid ejector to the container body.

"Means for Solving Problems" A cylinder 3 vertically disposed inside the container body 1 and a cylindrical piston 9 fitted into the cylinder are connected to the stem 10.
The nozzle 1 is attached to the lower end of the stem, and the nozzle 1 is attached to the upper end of the stem.
an actuating member 17 into which a head 16 with a 5 is fitted;
A spring 19 that urges the actuating member upward relative to the cylinder and an outward flange 6 attached to the upper part of the cylinder are loosely inserted into a screw tube 20 that is screwed onto the outer surface of the neck and neck of the container body. At the upper end, an inward flange 21 that engages with the upper surface of the outward flange 6
A mounting member 23 with a screw attached thereto, and a threaded cylindrical portion 25 through which the stem is vertically movably inserted and screwed onto the outer surface of the connecting portion between the stem and the head 16 are locked from the upper end via an outward flange 26. The cylindrical part 27 is installed vertically,
The locking cylinder part is made up of a cylindrical actuating member retainer 24 that is fitted onto the outer surface of the cylinder upper end cylinder part 3a that projects upwardly from the outward flange 6, and the cylinder upper end part 3a and the locking cylinder part 27 have two upper and lower parts. By providing a locking means that can be locked at the upper position, when both cylinder parts are locked at the upper position, the mounting member can be rotated with respect to both cylinder parts, and the locking cylinder can be rotated from the upper locking state. By pushing down the part 27, both cylinder parts are locked at the lower part, and at this time, the engaging teeth 29 and 22 provided on the lower end of the locking cylinder and the inner periphery of the inward flange 21 of the mounting member are engaged. I shaped it to fit.

"Function" As shown in FIG. 1, when the operating member holder 24 is locked above the cylinder upper end cylindrical portion 3a, the mounting member 23 can freely rotate with respect to the operating member holder 24 and the cylinder 3. Then, insert the cylinder 3 into the container body, align the nozzle 15 with the reticle affixed to the container body 1, and turn only the mounting member to screw the threaded cylinder 20 into the neck of the container body. The outward flange 6 of the cylinder is securely clamped between the upper end of the mouth and neck of the container body and the inward flange 21 by tightening, and from this state, the head 16 is driven downward to lower the operating member presser 24. As a result of the lowering, the cylinder upper end cylindrical portion 3a and the locking cylindrical portion 27 engage with each other at a lower position as shown in FIG.
In addition, the engaging teeth 29 and 22 provided on the lower end of the locking cylinder and the inner peripheral part of the inward flange 21 of the mounting member 23 mesh with each other, so that the actuating member presser 24, the mounting member 23, and the cylinder 3 are moved against the container body 1. connected together.

"Example" 1 is a container body, and the mouth and neck part 2 is erected upward.

A cylinder 3 is vertically installed inside the container body. The cylinder has a suction valve 4 at the bottom, an outward flange 6 which is placed from the top to the upper end surface of the mouth neck of the container with a packing 5 interposed therebetween, and a cylinder which projects upwardly from the flange. Two engagement protrusions 7 and 8 are provided on the upper and lower sides of the outer surface of the upper end cylinder portion 3a.

A cylindrical piston 9 is fitted into the cylinder, and a stem 10 is erected by fitting the piston to the outer surface of the lower part so as to be able to move up and down by a certain height, and a nozzle 15 is attached to the upper end of the stem. head 1
6 is fitted. The stem has a bottom wall 11 that closes the lower surface of the stem, and a tapered portion 1 extends from the outer periphery of the bottom wall.
A large-diameter cylindrical portion 13 hangs down through the tube 2, and a ball valve holder 14 of the suction valve is suspended from the bottom wall. The cylindrical piston 9, stem and head are the actuating member 1.
7. The cylindrical piston 9 and the valve hole 10a bored in the lower part of the stem 10 form a discharge valve 18, and the discharge valve opens as the cylindrical piston rises.
Further, the discharge valve is closed due to the downward movement.

A coiled spring 19 is mounted within the bottom of the cylinder and urges the actuating member upward.

The outward flange 6 at the top of the cylinder mentioned above is loosely inserted into a screw tube 20 screwed onto the outer surface of the neck of the container body, and an inward flange 21 is attached to the top end of the screw tube. It engages with the upper surface of the orientation flange 6. A plurality of teeth 22 are projected from the inner periphery of the inward flange so that the tips of the teeth do not come into contact with the outer surface of the cylinder upper end cylindrical portion 3a. These threaded cylinders and inward flanges constitute the mounting member 23.

Reference numeral 24 denotes an actuating member holder, which is a threaded cylindrical portion through which the aforementioned stem 10 is inserted so as to be movable up and down, and the upper end of the stem is fitted into the lower outer surface of the fitting cylinder 16a hanging down from the head 16. 25, a locking cylindrical part 27 is vertically provided via an outward flange 26 projecting from the upper end of the threaded cylindrical part, and the cylindrical part is fitted onto the outer surface of the cylinder upper end cylindrical part 3a. A protrusion 28 provided around the inner surface of the cylindrical portion is locked to the lower surface of the upper locking protrusion 7 on the outer surface of the cylindrical portion at the upper end of the cylinder. Also, a plurality of teeth 29 are provided hanging from the lower end surface of the locking cylinder for engaging with the teeth 22 of the inward flange of the mounting member described above. An intermediate cylinder 30 extending vertically from the lower surface of the outward flange is fitted into the inner surface of the locking cylinder part 27. While the protrusion 28 is engaged with the lower surface of the upper locking protrusion 7, the teeth 22 and 29 are not engaged, and the actuating member presser 24 is pressed down against the cylinder upper end cylindrical portion 3a, and the lower locking protrusion 8 is pushed onto the lower surface of the lower locking protrusion 8. When the protrusions 28 are engaged, the teeth 22 and 29 mesh, and in this way the cylinder 3, the actuating member presser 24, and the mounting member 23 are integrally connected.

"Effect of the invention" The present invention has the above-described configuration, and the locking cylinder part 27 of the actuating member presser is fixed to the cylinder upper end cylinder part 3a.
Since it can be locked in two positions, upper and lower, and the mounting member can rotate relative to the cylinder in the upper position, the cylinder can be inserted into the container body as described above, and the nozzle and the container body can be aligned. From this state, only the mounting member 23 is turned to tighten the screw tube 20 to the neck of the container body, and from this tightened state, the operating member holder 24 is pushed down through the head 16 to lock it in the lower position, and in this way, Since the cylinder, the operating member presser, and the mounting member can be integrally connected, it is easy to align the orientation of the container body and the nozzle, and the liquid ejector can be easily mounted to the container body.
