[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid injection pump.

[0002]

[Prior art]

Conventionally, there has been used a liquid discharging pump which is configured so that a liquid in a container is sucked up into a cylinder by vertically moving a press-down head and discharged from a nozzle hole of the head. . These are configured such that a lower end cylinder is hung down into the container body by a mounting cap fitted to the mouth and neck of the container body, and a press-down head with a nozzle at the upper end is vertically movably protruded above the mounting cap.

When a conventional pump of this kind is used, a slight force is required to push down the head, and this tendency is particularly remarkable when the container is large or the liquid content is high in viscosity.

The present invention has been made in view of the above points, and proposes a liquid pouring pump that can easily press down a head with a small force.

[0007]

When the tip of the upper surface of the push-down plate 12 is pushed downward from the state shown in FIG. Since the distance between them is longer, the head 5 can be pushed down with a much smaller force than when the head 5 is pushed down directly.

In the embodiment shown in FIGS. 7 to 9, when the finger-holding lever 18 is pulled backward from the state shown by the solid line in FIG. 7 (at the position indicated by the two-dot chain line), the head 7 is similarly pushed down by a small force. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show an embodiment of the first aspect of the present invention. In the drawings, reference numeral 1 denotes a liquid discharge pump. The pump 1
It comprises a pump body 2 and a push-down member 3 detachably attached to the body.

The pump body 2 is provided with a mounting key
By fitting the cap 4 around the mouth and neck of the container body,
Cylinder 5 with the lower end suspended in the container
Fixed to the body and move up and down with a biasing bear from inside the cylinder
Press-down head with protruding as possible and with nozzle 6 at the tip
7 by vertically moving the vertically moving member fitted with
Pumps the liquid inside the container by the action of the built-in pump mechanism.
It is of a known configuration configured to be discharged from the nozzle hole of the head .

The push-down member 3 is provided with a mounting portion 9 having a flat C-shape formed by extending a pair of inward flanges 8 from upper and lower edges of an arc-shaped peripheral wall. 4 is press-fitted from the rear and is detachably mounted on the pump main body 2, and a columnar support portion 10 that rises obliquely rearward and upward from the rear surface of the mounting portion 9 is integrally extended. The support portion 10 is curved rearward as it goes upward, and is formed in a hollow shape by recessing the center of the rear surface forward.
Further, a push-down plate 12 is provided at the rear end edge of the upper surface of the support portion 10 with the rear end edge rotatably connected via a thin hinge 11. The depressing plate 12 extends obliquely upward and forward from the thin hinge 11, has a rectangular shape extending substantially in the upper end of the nozzle 6 in a longitudinal direction, and has a slightly upwardly curved central portion. At the center of the lower surface, a pressing projection 13 is provided to project the lower end to the upper surface of the lowering head 7 of the pump body 2, and the lower end is pressed into the base end of the nozzle 6 of the lowering head 7 from the front lower surface. A locking plate 14 that can be combined is vertically provided.

The liquid discharge pump 1 configured as described above has
The head 7 is lowered by depressing the press-down plate 12 when used by mounting it on the container body. When the press-down of the press-down plate 12 is released, the head 7 is raised by the upper biasing mechanism provided in the pump, and the head 7 is lifted. The structure is such that the liquid in the container body is discharged from the nozzle hole with the vertical movement of 7.

FIGS. 4 to 6 show another embodiment of the invention described in claim 1. In this embodiment, the nozzle 6 of the pump main body 2 is configured as a flexible nozzle 15. FIG. The tip of the nozzle 15 is inserted and locked into a locking ring 16 provided at the front of the lower surface of the push-down plate 12, so that the push-down member 3 can be easily attached to the pump body 2.

FIGS. 7 to 9 show an embodiment of the invention described in claim 2. In this embodiment, a pressing plate 12 is provided with a thin hinge 1 at the upper end of a support plate 10. FIG.
1 while pivotally connecting the rear end through
From the nozzle insertion hole 17 formed in the center of the bent front part,
A front part in which the chisel 6 is protruded so as to be vertically movable and bent.
The lower end portion is configured as a finger hanging lever 18.

The pump body 2 and the pressing member 3 in each of the above embodiments are preferably made of synthetic resin.

[0017]

[Effect of the Invention] As described above, the liquid injection pump of the present invention has the above-described structure, so that the head can be easily pushed down with a small force. It is suitable when the body is large.

The pressing member 3 is located behind the pump body 2 .
Easy mounting by fitting the mounting part 9
Can be removed, and depending on the application, remove the push-down member
To provide versatility to the pump
Can be done.

In the invention described in claim 2, for example,
For example, after the nozzle 6 is inserted through the nozzle insertion hole 17,
By fitting the mounting portion 9 from behind the
The lowering member 3 can be easily mounted, and the operation can be performed by gripping the finger-holding lever 18 of the lowering plate in a trigger manner, so that a stronger force can be easily transmitted to the lowering head 7.
