Problems solved by technology

This inadvertent discharge not only pollutes the surroundings, but also wastes this discharge.
Another problem is that in the process of circulation, it is also possible to inadvertently press the hand pressure part
However, the problem with this method is that the sleeve is easily lost
[0015] In above-mentioned prior art, can not solve above-mentioned two problems at the same time

Embodiment 1

[0111] figure 1 and figure 2 Example 1 is a representation of the pump. figure 1 is a front view of a liquid container 2 with a pump 1 . The stopper 4 which limits the amount of depression of the head 3 of the pump is shown in partial section. figure 2 It is a central longitudinal section view.

[0112] as figure 1 and figure 2 As shown, the pump 1 in which the liquid container 2 is integrated with the cap part 7 at the upper opening 6 of the bottle-shaped container body 5 is provided as a cap. The container body 5 is widely used as a soft resin material such as polypropylene, but the material is not limited, and it can also be made of hard resin, glass and other materials, and the general circulation container can be selected appropriately.

[0113] This pump 1 is a pump of very general construction related to the discharge function itself of the container contents of a push-down type liquid pump, which is made as part of the cover of the liquid container 2, and b...

Embodiment 2

[0126] Figure 5 to Figure 9 Example 2 representing the pump, Figure 5 It is a front view of important parts when the stopper 4 is set at the maximum discharge position, Figure 6 (a) is a partial longitudinal sectional view of the head 3 of the pump at this time and Figure 6(b) A partial longitudinal sectional view of the pump head 3 when the stopper 4 is installed at the pump head fixing position.

[0127] Such as Figure 5 and Figure 6 As shown, in this embodiment, the stopper 4 is installed in the head 3 of the pump. The head 3 of the pump forms an internal thread 25 on the lower inner periphery of the outer cylinder 19 . The connecting pipe 18 is inserted into the inner cylinder 20 . And, a stopper 4 having an external thread 24 threadedly engaged with the internal thread 25 is accommodated in the head 3 of the pump. The stopper 4 is provided with a flange portion 10 at the lower end of a cylindrical body having an external thread 24 on the outer periphery there...

Embodiment 3

[0132] Figure 10 Example 3 of the pump of the present invention is shown, (a) is the fixed position of the head of the pump, and (b) is the state where the stopper 4 is installed at the maximum discharge position.

[0133] In this embodiment, a stopper 4 is used in which an external thread 24 is formed on the outer periphery of the connecting pipe 18 , an internal thread 25 is threadedly engaged with the external thread 24 of the connecting pipe 18 , and a stopper 4 is used. exist Figure 10 Among them, the cylindrical portion 31 covering the cap member 7 is provided on the outer edge of the planar portion 32 , and the scale 29 is provided on the cap member 7 . The flat portion 32 of the stopper 4 is positioned in a range between the lower end 27 of the pump head 3 and the upper face 28 of the cap member 7 to set the pressing amount L steplessly.

[0134] In addition, in this embodiment, in order to prevent the pump head 3 and the connecting pipe 18 from rotating relative t...

Abstract

A push-down liquid pump that forms a part of a lid body of a liquid container and pumps up a fixed amount of liquid from inside of a container main body by push-down operation. A stopper for limiting the push-down amount of the push-down portion is arranged movably in a space provided for the movement of the pump push-down portion in such a way that the movement amount of the stopper is adjustable by moving the stopper in a position between a maximum movement amount position and immobile position. This enables a fixed amount of liquid corresponding to the push-down amount of the push-down portion to be dispensed.

Description

technical field [0001] The present invention relates to a hand pump for metering and distributing a certain amount of liquid from a liquid container, in particular to a pump with quantitative metering function which can set the metered amount arbitrarily and adjust the discharge amount . Background technique [0002] Recently, as containers for shampoo or detergent, liquid containers with pumps, which are constructed with hand-pumped pumps as part of the lid, are widely used. Although the fine structure of the pump is various, basically there are two one-way valves in the cylinder, the upper and lower plungers connected by the connecting rod from the hand pressure part, and the plungers are provided with springs and other return valves. The basic structure of the bit organization. [0003] Its function is that when the hand pressure part is pressed down, the plunger descends in the cylinder, so the internal pressure on the lower side of the plunger in the cylinder rises, c...
