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 forming the spray head in the form of a nozzle tube with an operating lever and by molding it together with the head cap 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. This spray head 3 and head cap 2 are molded as the same part from synthetic resin material. It is manufactured.

The container body 1 is formed by wrapping the upper end of the body 4 with the lower end of a tapered shoulder 5 with a lower protrusion 6, and wrapping the upper end of the shoulder 5 with the peripheral edge of the top wall (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 has top walls 9, 9 with an appropriate gap formed in the diameter part in the front and rear direction from the left and right sides of the upper surface of the annular fitting part 8 at the bottom, and the outer circumferential surface is inclined to widen downward. It has a shape in which half-circumferential bodies 10, 10 are erected and facing each other, and a protrusion (not shown) on the inner periphery of the fitting part 8 is fitted into the groove, and is fitted to the top of the container body 1. Although the semicircular bodies 10, 10 are shaped like peripheral walls, they may also be solid bodies, that is, half-column shaped.

The spray head 3 has a nozzle pipe 12 with a nozzle hole 11 opened in the front surface, and an appropriate gap 13, 13 is provided between the semicircular bodies 10, 10 so that the upper surface thereof is at the top. The walls 9, 9 are arranged so that they are substantially flush with each other, and from the lower surface of this nozzle pipe 12, a hanging tube 14 that fits and communicates with the upper end of the stem 7 is hung, and from the rear end, it is curved rearward and downward. A hanging plate-like operating lever 15 is provided, and a connecting piece 16 is provided that can be broken at two locations on each of the left and right sides of the nozzle pipe 12.
... are connected to the top walls 9, 9, giving the nozzle pipe 12 the function of a virgin seal.

The spray head 3 is formed integrally with the head cap 2, with the lower front surface of the nozzle pipe 12 connected to the upper end of a swingable support plate 17 that stands up from the gap between the front surfaces of the semicircular bodies 10, 10. .

When using the above structure, first break the connection piece 16 of the virgin seal, and then break the container body body 4.
Push the operating lever 15 in the direction of arrow A with the fingers of the hand that is gripping it. Then, since the support plate 17 is swingable, the nozzle pipe 12 descends, and the stem 7
, the discharge valve provided above inside the container body 1 opens and the internal liquid of the container passes through the stem 7 and is sprayed from the nozzle hole 11 of the spray head 3.

According to the present invention, the head cap 2 and the spray head 3 are manufactured as an integral part.
The structure is simplified because the number of steps is reduced and there is no need to assemble both parts. In addition, the nozzle pipe 12 has a virgin seal function and is connected to the top walls 9 by breakable connecting pieces 16, so that it cannot be manipulated by mischief etc. during the distribution process before it reaches the consumer. This can be prevented and product reliability can be improved. Further, the operating lever 15 is located away from the support plate 17 serving as a fulcrum and below the nozzle pipe 12, so it is easy to operate, and even a young person with small hands and weak strength can operate it easily.
Further, since the head cap 2 and the spray head 3 including the operating lever 15 are configured to fit within the outer shape of the can container body 1, there are no protruding parts that would get in the way, which is advantageous for packaging and transportation.

Claims (1)

[Scope of utility model registration request] A head cap is formed by standing a can container body 1 and semicircular bodies 10, 10 facing left and right with an appropriate gap from a fitting part 8 at the bottom, and is attached to the top of the container body 1 by the fitting part 8. 2, and a nozzle pipe 12 with a nozzle hole 11 opened in the front and an operating lever 15 that hangs downwardly from the rear end, is inserted into the gap between the semicircular bodies 10, 10.
A hanging cylinder 14 is provided vertically, which is connected to the top walls 9, 9 by breakable connecting pieces 16, and is fitted and communicated with the upper end of the stem 7 which protrudes through the top wall of the container body 1 from the lower surface. The spray head 3 is connected to a head cap 2 by connecting the upper end of a swingable support plate 17 which extends from the front lower surface of the nozzle pipe 12 to the front gap between the semicircular bodies 10, 10.
