Description

[Detailed Description of the Invention] This invention relates to an aerosol sprayer in which a spray liquid is sealed together with a liquefied gas within a main body of the container, and is particularly intended to be simple in structure and inexpensive to manufacture.

An explanation of the embodiment of this invention with reference to the drawings is as follows:
As shown in FIG. 1, the entire structure includes a stopper 2 that covers the upper end opening of a container main body 1 filled with spray liquid and liquefied gas for injection, and is fixed by a tightening ring 3, and an injection pipe is attached to the stopper 2. 4 is press-fitted and installed vertically.

This plug body 2 is made of a soft elastic material such as soft rubber, and as shown in FIG. A series of annular grooves 7 are provided on the lower edge of the inner circumferential surface of the vertical tube 6, and three small holes 8 are formed in the grooves by equally dividing the circumference.

The injection pipe 4 is made of hard resin or the like, and the tip of the straight pipe that fits inside the vertical tube 6 is narrowed to provide an injection port 9, and a groove 10 for preventing slippage is provided around the base end circumferential surface. The proximal end is press-fitted from inside the vertical tube 6 to the bottom of the annular groove 7 to be fixed upright.

This device has the above-mentioned structure, and as shown in FIG. 1, in the normal state, the base end of the injection pipe 4 is in pressure contact with the inner and outer peripheral surfaces of the annular groove 7, and the small holes 8 and the inside of the injection pipe 4 are in pressure contact with each other. Since it is isolated, the spray liquid cannot be sprayed into the main body 1 of the container, but as shown in Fig. When the injection pipe 4 is slightly tilted, the base end of the injection pipe 4 pushes the circumferential wall of the annular groove 7 to one side, and the small hole 8 and the inside of the injection pipe 4 are communicated through the gap 11 created thereby, and the spray liquid becomes the injection gas. When pressed, the water is ejected from the spout 9. In this case, since the small holes 8 are located on three sides of the circumference, even if the injection tube 4 is tilted in any direction, one of the small holes 8 will open, and the plug body 2 will open. Since it is a soft elastic body and the proximal end of the injection pipe 4 is held evenly by the vertical tube 6, its operation is reliable. In addition,
It is more efficient if the number of the small holes 8 is three or more, but in consideration of the strength of the annular groove 7, the number is usually three.

FIG. 4 shows another embodiment different from FIG. 1,
Each part is indicated by the same reference numerals as in FIG. In this case, a collar 12 is integrally provided vertically on the lower surface of the disc 5 of the stopper 2, and a liquid suction pipe 14 is fitted into the inner side 13 of the collar 12. In this embodiment, when the injection pipe 4 is tilted, the spray liquid is transferred to the liquid suction pipe 1.
4 and enters the injection pipe 4, there is no need to turn the entire container upside down.

As described above, this invention has an extremely simple structure, so it can be manufactured at low cost, but the injection pipe can be firmly attached, and the injection direction is not limited, so spraying can be performed quickly and easily. There are many advantages such as being able to
