Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a manual liquid dispenser.

"Prior Art" Liquid ejectors are used as atomizers, bubble ejectors, or liquid ejectors that eject liquid as it is by changing part of the nozzle. The basic structure of these is attached to the upper end of the cylinder. The outer flange is attached to the top of the container body by engaging the outer flange of the container with the top surface of the container body and hanging the cylinder into the body of the container and the upper end of the cylinder screwed to the outer surface of the neck of the body mouth. A mounting cylinder provided with an inward flange for clamping the cylinder by sandwiching it between the surface and a surface; and an operating member for standing up the stem by upward biasing from the inside of the cylinder and fitting the pressing head to the upper end of the stem. In addition, the liquid inside the container is discharged into the cylinder by the vertical movement of the actuating member with respect to the cylinder, and the liquid inside the cylinder is discharged from the nozzle of the pressing head via the stem.

[Problems to be Solved by the Invention] In a conventional liquid ejector, a lower limit and an upper limit of a cylindrical piston that is attached to a lower end of a stem and moves up and down in a cylinder are predetermined, and the vertical movement causes a substantially constant value. It was designed to eject liquid.

However, it is desirable that the discharge amount be variable depending on the discharge liquid.

The present invention is provided so that the discharge amount can be freely changed by an extremely simple mechanism.

"Means for Solving the Problem" The outward flange 3 attached to the upper end of the cylinder is engaged with the mouth top surface of the container body 1 and hung down into the container body, and screwed onto the outer surface of the neck portion of the container body. The mounting cylinder 4 having an inward flange 6 for fixing the cylinder by sandwiching the outward flange 3 between the outer flange 3 and the top surface of the container body, and an upward bias from the inside of the cylinder. The stem 8 is erected, and the operating member 7 is fitted with the pressing head 10 on the upper end of the stem. The vertical movement of the operating member 7 with respect to the cylinder 2 causes the liquid in the container to pass through the stem and the nozzle 9 of the pressing head.
In the liquid ejector provided so as to eject from, the screw cylinder 14 is screwed onto the outer surface of the stem fitting cylinder 13 hanging from the pressing head, and the lower end of the screw cylinder 14 and the screw cylinder when the operating member is pressed down.
14 The distance between the inward flange 6 where the lower end contacts is
Adjustment is possible by raising and lowering the screw cylinder 14 with respect to the stem fitting cylinder 13.

"Operation" When the screw cylinder 14 is screwed down from the pressing head 10 from the state shown in FIG. 1, the distance between the lower end of the screw cylinder and the inward flange 6 of the mounting cylinder becomes short, and therefore the operating member 7 Stroke becomes smaller and the liquid discharge amount also decreases.

"Example" 1 is a container body, 2 is a cylinder that hangs into the container body by engaging an outward flange 3 at the upper end of the cylinder with the top surface of the container body mouth,
Reference numeral 4 denotes an inward direction for fixing the cylinder 2 to the container body by holding the outward flange 3 between the upper end of a tubular portion 5 screwed onto the outer surface of the neck of the solution body and the top surface of the container body. Flange 6
Reference numeral 7 denotes an attachment member, and 7 is an actuating member in which a stem 8 is erected by upwardly urging it from the inside of the cylinder, and a push-down head 10 with a nozzle 9 is fitted to the upper end of the stem. A suction valve is provided at the lower end of the cylinder, and a suction pipe 11 communicating with the suction valve hole is hung in the container body. Further, a cylindrical piston is attached to the lower end of the stem 8 by a coil spring provided in the cylinder. Bias the cylindrical piston upwards,
A discharge valve (12) is provided on the upper end of the stem, and an upper part of the stem is fitted into a stem fitting cylinder (13) hanging from a pushing head (10).
A guide cylinder 5a is erected from the inward flange 6 of the mounting cylinder 4. The liquid ejector is almost the same as the conventional example except that the inward flange 6 is wide, and the liquid inside the container is ejected from the nozzle by the vertical movement of the operating member.

A screw cylinder 14 is screwed into the stem fitting cylinder 13. The screw cylinder is provided such that, when the operating member 7 is pushed down against the container body, the lower end thereof contacts the upper surface of the inward flange 6 and serves as the lower limit of the operating member. It is possible to increase or decrease the liquid discharge amount by changing the stroke of the operating member by screwing up and down by 14.

"Effect of device" Since the stroke of the operating member 7 is variable as described above, the liquid discharge amount can be freely changed by adjusting the stroke. Therefore, for example, when used for shampoo discharge, it can be used for adults and children. There is a convenience that can correspond to the difference in consumption amount with, and the adjustment of the stroke is
By vertically moving the screw cylinder 14 that is screwed into the stem fitting cylinder 13 that hangs down from the pressing head 10, the distance between the inward flange 6 and the lower end of the screw cylinder that the lower end of the screw cylinder contacts when the operating member 7 is pressed down. Since it is provided for adjustment, the structure is extremely simple and can be manufactured at low cost.
