Description

[Detailed description of the invention] (Field of industrial application) The present invention fits into the outlet of a liquid container (such as a can or bottle) and drains the liquid from the outlet by tilting the container. This invention relates to a removable liquid injection device for the purpose of preventing pulsation of flowing liquid that sometimes occurs.

(Prior art) When transferring a stored liquid from a conventional liquid container to another container, the container is generally lifted and tilted, and the stored liquid is drained from the outlet, or a commercially available manual pump is used. are doing.

(Problem that the invention aims to solve) However, since the liquid containers currently in use do not have vents, when taking out the stored liquid using the conventional method, the former method is used because the space inside the container is filled with drained liquid. Since outside air intermittently flows in and causes a pulsating flow in the drained liquid, it is necessary to adjust the tilt of the container in order to drain smoothly, and the latter requires manual pump operation and after use. There were problems such as troublesome handling and storage.

(Means for solving the problem) The present invention solves the above problem, and the upper opening of the truncated conical cylinder, which slightly expands downward, is fixed by a lid plate having a ventilation hole at the rear. A transverse partition plate is provided in the cavity of the conical cylinder, and the front edge of the conical cylinder is separated from the front wall by an appropriate distance at the middle of the rear wall of the conical cylinder. A liquid injector whose entire body is integrally molded from a slightly flexible synthetic resin material, with a discharge pipe communicating with the cavity protruding forward, and the lower end is used to accommodate liquid containers such as cans or bottles. When the liquid container is fitted into the liquid outlet and the liquid container is tilted to discharge the stored liquid to the outside from the discharge pipe, the pulsating flow of the discharged liquid that occurs is caused by the air flowing in through the vent hole provided in the lid of the syringe body. The purpose of this invention is to prevent the above, and will be explained below with reference to the embodiment shown in the figures of the present invention. , covered by a lid body 4 provided with a ventilation hole 3 at the rear, a ring-shaped fastening flange 5 whose lower end periphery protrudes inward, and whose rear outer peripheral surface is the rear wall of the conical cylinder 1. 6, and the front end edge 8
The partition plate 11 is provided in the hollow part 12 of the conical cylinder 1 in a substantially horizontal direction so as to be separated from the inner circumferential surface 10 of the front side wall 9 by an appropriate distance t. A syringe main body 15 is formed with an air passage cavity 13 at the top and a discharge liquid passage cavity 14 at the bottom. Discharge pipe 1 provided with a connection pipe connection part 16 (the figure shows the case of a connection thread part)
The liquid injection device A of the present invention is constructed by integrally molding the entire body from a slightly flexible synthetic resin such that the passage hole 18 is connected to the cavity 12 of the syringe main body 15 at the rear end of the liquid injection device 7. do.

Reference numeral 19 in the figure is a tongue plate portion for removing the liquid injection tool fitted into the liquid container B.

(Function) Next, the function of the present invention will be explained with reference to the usage condition shown in FIG.
The stored liquid outlet 21 of the liquid container B with the outlet lid removed is brought into contact with the liquid container B in a facing manner, and the injector A is pressed downward so that the stored liquid outlet 21 of the liquid container B is brought into contact with the locking flange 5. , a liquid outlet cylindrical portion 2 protruding upward from the periphery;
2. An outward locking protrusion 23 provided on the upper end periphery of 2.
Fix the liquid injection device A to the liquid container B by press-fitting the liquid injector A.

Tilt the liquid container B and pour the stored liquid into the liquid injection tool A.
If the liquid is discharged to the outside from the discharge pipe 17 through the discharged liquid passage cavity 14, the pulsating flow of the stored liquid that occurs when being discharged from the liquid container B will flow through the air passage cavity 13 from the vent hole 3. The impulse is absorbed by the air inside the discharge liquid passage cavity 14, and the stored liquid flows out continuously and smoothly from the discharge pipe 17.

Further, the liquid injector A can be easily removed from the liquid container B after discharging the stored liquid by holding the removal tongue plate 19 and pulling it upward.

In addition, C in the figure indicates that the rear end part that fits into the tip of the discharge pipe 17 is connected to the discharge pipe 17 as necessary when discharging the stored liquid.
The connecting part 24 (the figure shows the case of a screw hole) that fits into the connecting pipe connecting part 16 of An example of a removable injection connection tube shown in FIG.

(Effects) The liquid injector of the present invention has a simple structure, can be mass-produced by molding synthetic resin, is inexpensive, is small, convenient to handle, and can be easily attached and detached from the liquid container. It is easy to use, and by using the present invention, it is possible to prevent the scattering of drained liquid due to the pulsating flow that occurs when transferring the stored liquid from a conventional liquid container to another container, and to prevent such impact on the liquid container. It has excellent practical effects.

(Embodiment) FIGS. 4 and 5 show an embodiment of the present invention, in which in the liquid injection device A described above, a suitable height is placed in the axial direction at the lower end 27 of the peripheral wall of the truncated conical cylinder 1. A tightening ring 30 is provided with a plurality of narrow notched grooves 28, 28, .
After press-fitting the locking protrusion 23 of the liquid container B into the locking flange 5 of the liquid injection tool A', press the tightening ring 30. The liquid injection tool A' is lowered to compress the narrow notched grooves 28, 28, . to prevent the injection tool A' from coming off the container B during use.When removing the injection tool A' from the container B, raise the tightening ring 30 and remove the removal tongue plate. This can be easily done by holding the handle 19 and pulling it upward.

The effect of preventing pulsation of the stored liquid during the work of discharging the stored liquid is the same as in the case of the liquid injection device A described above.
