Description

[Detailed explanation of the idea] The present invention relates to an aerosol sprayer.

As is well known, an aerosol sprayer has a liquid gas cylinder built into a can containing liquid, and uses the air pressure of the liquefied gas to increase the internal pressure.
The discharge valve is opened by depressing the spray head at the upper end of the stem protruding from the container body, and pressurized liquid is sprayed while the spray head is depressed. In this type of sprayer, the head cap and the spray head are usually separate pieces, which requires time and effort to manufacture and assemble, and the push-down operation is not necessarily convenient.

The present invention attempts to eliminate the above-mentioned drawbacks by molding the head cap and spray head as one piece.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a can container body, 2 is a head cap attached to the top of this container body 1, and 3 is a spray head built into this head cap 2.
and 3 are integrally molded and manufactured as one piece from synthetic resin material.

The container body 1 is formed by wrapping the upper end of the body 4 and the lower end of the tapered shoulder 5 with a lower protrusion 6, and wrapping the upper end of the shoulder 5 with the top wall periphery (not shown) and the upper protrusion. A concave groove is provided just below the protrusion.
Further, a stem 7 penetrates and protrudes from the top wall.

The head cap 2 is of an inverted cup shape, and has a hook-shaped belt-shaped hole 10 in the diameter part of the top wall 8 in the front-rear direction and continuous thereto halfway up the front part of the peripheral wall 9.
Further, an engaging protrusion 11 is provided around the inner periphery of the lower end of the peripheral wall 9, and the engaging protrusion 11 is fitted into the engagement groove to be fitted to the top of the can container body 1. 12
This is a peephole for checking the direction mark of the suction tube set on the shoulder of the container body 1.

The spray head 3 consists of a nozzle pipe 13 and a nozzle pipe cover 14 with a trigger, and the nozzle pipe 13 has a nozzle hole 15 opened in the front surface and a hanging cylinder 16 hanging from the lower surface that fits and communicates with the upper end of the stem 7. death,
Furthermore, engaging protrusions 17 are provided on both left and right outer surfaces of the front portion and are disposed in the band-shaped holes 10. The nozzle tube cover 14 is a key-shaped one with a trigger 18 that hangs downward integrated at its tip, and a window 19 at the upper end of the trigger 18.
Furthermore, an engaging protrusion 20 that engages with the engaging protrusion 17 is provided on the inner surface of the corner, and its rear end together with the nozzle pipe 13 is integrally connected to the rear upper end of the peripheral wall 9 by a common flexible hinge 21. It is molded and manufactured as one part with the head cap 2. That is, both 13 and 14 are integrally molded in the state shown in FIG. 22
is a horizontal bar-shaped baffle plate provided in the side hole of the peripheral wall 9 of the band-shaped hole 10 so as to prevent the nozzle pipe 13 from descending, and has the function of a virgin seal.

When using the above structure, the virgin seal 22 is first broken, and then the trigger 18 is pulled with the index finger of the hand that grips the container body 1. Then, the nozzle pipe 13 descends using the hinge 21 as a fulcrum, thereby pushing the stem 7 downward, so the discharge valve provided in the upper part of the container body 1 is opened and the liquid in the container body 1 is discharged from the stem 7. Spray from the through nozzle hole 15.

According to the present invention, since the head cap 2 and the spray head 3 are molded and manufactured as one part, there is no need to assemble them, and the structure is simplified.
Furthermore, since the baffle plate 22 has a virgin sealing function, the reliability of the product can be improved. In addition, since the spray is a trigger type, it is easy to operate, and since the trigger 18 has a shape that fits within the outer shape of the container body 1, it does not protrude and get in the way, which is advantageous for packaging and transportation. Since it is separated from the pipe 13, it is easy to clean the dirt with the spray liquid.
