[Detailed description of the invention]

[0001]

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

[0002]

2. Description of the Related Art Many injection containers of this kind have been proposed in the past (for example, Japanese Utility Model Laid-Open No. 1-128859, Japanese Utility Model Laid-Open No. 2-28859).
No.81653), from inside the cylinder that hangs down inside the container,
When the operating member having a cylindrical piston at the lower end of the stem and a push-down head with a nozzle at the upper end of the stem is urged upward to stand up, and the operating member is pushed down through the push-down head, the liquid in the cylinder is added. When the pressure is discharged from the nozzle and the press-down head is released, the cylindrical piston rises to make the pressure in the cylinder negative, and the liquid stored in the container is sucked into the cylinder.

[0003]

OBJECTS OF THE devised to solve the above this type conventionally container, for discharging the cylinder liquid pressurized, especially when the viscosity of the liquid is small is discharged well-energized, close the nozzle hole front end to the wall of a bathroom if e Example injection Then the storage liquid Te, was sometimes soil the clothes injection solution rebounded largely.

[0004] merits is the rear end surface of the stem hole, closed by a partition wall which is inclined to the rear upper side, and the partition wall in the vertical direction
By providing a vertical hole , the injection speed was reduced to prevent the liquid from scattering.

[0005]

An upright vertical member is urged upward from an inside of a cylinder hanging down into a container body, with an operating member having a cylindrical piston at a lower end of a stem and a pressing head with a nozzle at an upper end of a stem. In a liquid pumping container of the type pump type, the press-down head 6 with a nozzle is attached to the upper outer surface of the stem 5 with the inner surface of a peripheral wall vertically suspended from the lower surface of the top wall 1; And a nozzle 2 that protrudes forward from the upper front of the nozzle and that communicates with the stem 5. The rear end face of the nozzle hole is closed by a rearwardly inclined wall 8, and a stem is provided at the center of the inclined wall. A vertical hole 7 having a smaller diameter than the inner diameter of No. 5 and a vertical direction was formed.

[0006]

[Action] and depresses the actuating member through the pressing head 6 Figure 1 from indicate to state, the liquid in the cylinder 12 is pressurized, the nozzle 2 pressurized liquid through the stem 5 and the vertical hole 7
And at this time, the pressurized liquid
Collides with the rear inner wall of the nozzle 2 and the nozzle hole is
Since the pressurized liquid is decompressed with a large diameter, the pressurized liquid is decelerated.
From the front end face of the nozzle hole at an appropriate speed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a known structure will be described in a very simple manner. The container of the present invention comprises a cylindrical piston ( not shown) at the lower end of a stem 5 and a nozzle 2 The actuating members respectively having the press-down heads 6 are urged upward to stand up, and the press-down heads 6
When the operating member is depressed through the nozzle, the liquid in the cylinder 12 is pressurized and discharged from the nozzle 2 and the depressing head 6
When the pressure is released, the cylindrical piston rises and the pressure in the cylinder 12 becomes negative, and the liquid stored in the container is sucked into the cylinder 12 through the suction pipe 15.

The pressing head 6 is formed by a head main body and a nozzle 2, and the head main body has a peripheral wall vertically suspended from a lower surface of the top wall 1, and the peripheral wall is formed by an inner peripheral wall 3 and an outer peripheral wall 11. The inner surface of the inner peripheral wall 3 is fitted to the upper outer surface of the stem 5, and a pressing rod 10 for determining the upper limit position of the ball valve 4 is suspended from the lower surface of the central portion of the top wall 1 surrounded by the upper end of the inner peripheral wall 3. Has been established. The nozzle 2 penetrates above the front portions of the inner and outer peripheral walls 3 and 11 and projects forward of the outer peripheral wall 11, and closes the rear end face of the nozzle hole with a rear upwardly inclined wall 8, and at the center of the inclined wall. The nozzle hole communicates with the stem 5 through a vertical hole 7 formed in the vertical direction.

[0009]

According to the present invention, the rear end face of the nozzle hole is closed by an inclined wall 8 extending upward and rearward, and a central portion of the inclined wall has a diameter smaller than the inner diameter of the stem 5 and a vertical direction. Since the vertical hole 7 is formed , the liquid in the cylinder 12 is added.
Pressurizes and causes the pressurized liquid to flow into the nozzle hole from the vertical hole 7
Because the diameter of the nozzle hole is larger than that of the vertical hole 7,
The liquid is depressurized and slows down, plus the incoming liquid
7 Slow down by colliding with the inner wall of the rear part of the nozzle 2
Therefore, the inflowing liquid slows down sufficiently before the nozzle hole.
The liquid is ejected from the end face , so that the ejected liquid is not scattered as in the related art. Also, as mentioned above,
The rear end face of the nozzle hole is closed by an inclined wall 8 and
By forming the vertical hole 7 so as to prevent the ejection liquid from scattering, it is possible to use the press-down head 6 with the nozzle as the head of the existing operating member, and to use an injection container in which the ejection liquid does not scatter. Can be obtained.
