Description

[Detailed explanation of the idea] The present invention relates to a trigger type sprayer.

Trigger-type sprayers are, for example, aerosol types in which a liquid gas cylinder is built into a can containing liquid and the internal pressure is increased by the pressure of the liquefied gas, and the spray head at the top of the stem protruding from the container body is triggered. When the trigger is pulled, it is lowered to open the discharge valve, and pressurized liquid is sprayed while the trigger is being pulled. In this type of atomizer, the trigger is usually exposed, and therefore, if the trigger is pulled in for any reason or by mischief during the distribution process, liquid will be sprayed and liquid will be wasted.

The present invention attempts to eliminate the above-mentioned drawbacks by providing a baffle plate with a virgin seal function to prevent the nozzle pipe from descending when the trigger is pulled.

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 and manufactured 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 and the periphery of the top wall with an upper protrusion 7. A concave groove 8 is provided just below the strip 7. Although not shown, a stem protrudes through the top wall.

The head cap 2 includes semi-cylindrical fitting members 11, 11 with reduced diameters, which are vertically disposed facing each other on the left and right with an appropriate gap, from an annular body 10 at the lower end of a peripheral wall 9 that is inclined to widen downward. A continuous belt-shaped hole 13 in the shape of a key is formed extending from the diameter part in the front-rear direction to the lower end of the front wall of the peripheral wall 9, and the fitting members 11, 1
The protrusions 14, 14 on the inner circumference of the container body 1 are fitted into the grooves 8, and the container body 1 is fitted to the top of the container body 1.

The spray head 3 has a hanging cylinder 17 which is fitted and communicated with the upper end of the stem from the rear lower surface of a nozzle pipe 16 with a nozzle hole 15 opened in the front surface, and a trigger type trigger is installed from the front lower surface of the nozzle pipe 16. The end of a plate member 19 extending rearward from the nozzle pipe 16 is fixed to the rear end of the top wall 12 of the head cap 2 by a flexible hinge 20 so that it can be raised and lowered. As shown in FIG. 1, they are arranged so as to fill the strip holes 13. Therefore, in Figure 1,
When the index finger of the hand that grips the container body 1 is placed on the trigger 18 and this trigger 18 is pulled,
The nozzle pipe 16 rotates counterclockwise about the flexible hinge 20, and this rotation pushes the stem downward, so the discharge valve provided above inside the container body 1 is opened and the inside of the container body 1 is discharged. The liquid passes through the stem and is sprayed from the nozzle hole 15 of the spray head 3.

In the present invention, a horizontal bar-shaped baffle plate 21 is provided at a location on the lower front surface of the nozzle pipe 16 above the circumferential wall side hole of the strip hole 13 of the head cap 2 to prevent the nozzle pipe 16 from descending when the trigger 18 is pulled. It is being constructed. This baffle plate 21 serves as a virgin seal, and is attached with such strength that it can be removed by forcibly applying force from the outside.
This baffle plate 21 may have any shape as long as it can fulfill its role.

According to the present invention, the baffle plate 21 having a virgin seal function is provided to prevent the nozzle pipe 16 from descending due to the pulling of the trigger 18, and the baffle plate 21 is provided with a virgin seal function.
Since the spraying operation cannot be performed unless the product is removed, it is possible to prevent manipulation by mischief etc. during the distribution process before the product reaches the consumer, and it is possible to improve the reliability of the product. Moreover, structurally,
It is extremely simple, as it is sufficient to simply install a bar in the belt-shaped hole 13 of the headcap 2. Also baffle board 2
1 can be removed by strongly pulling the trigger 18 and the nozzle pipe 16 descending can break it, so there is no trouble at all.
