Description

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

As is well known, an aerosol sprayer has a cylinder of liquefied gas built into a can containing a liquid, and uses the atmospheric pressure of the liquefied gas to increase the internal pressure.
The discharge valve is opened by pressing down 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 pressed down. Conventionally, many of these types of sprayers do not have a sealing function, and therefore, it is impossible to prevent tampering during the distribution process, and it cannot be said that the push-down operation is necessarily easy.

The present invention aims to provide an aerosol sprayer that has a virgin seal function to improve the reliability of the product, and has a spray head in the form of a nozzle tube with a trigger for easy operation.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figures, 1 is a can container body, 2 is a head cap attached to the top of this container body 1, and 3 is a nozzle tube-shaped spray head with a trigger. .

The container body 1 has a protrusion 6 extending between the upper end of the body 4 and the lower end of the shoulder 5.
A concave groove 8 is provided around the upper end of the shoulder portion 5, that is, directly below the top wall 7. A stem 9 projects through the top wall 7.

The head cap 2 has an annular fitting portion 10 at the lower end.
The left and right sides gradually become flat as they move upward, and the top part 11 becomes a band-shaped flat part in the front and back direction, and the front part is open, while the rear wall 12 is a vertical wall, and the skirt hangs curved behind it. 13
A cap body 14 having a bag-like outer shape is provided upright, and the upper half of the rear wall 12 is made thicker on the inner side to form a downward step part 15 in the middle.
1 has an opening 16 cut out from the front end, and is fitted onto the top of the container body 1 by engaging the engagement protrusion 17 on the inner periphery of the fitting part 10 into the groove 8. .

The spray head 3 has a nozzle hole 18 opened in the front surface and a hanging cylinder 20 which is fitted and communicated with the upper end of the stem 9 from the rear part of a nozzle pipe 19 which is disposed laterally on the rear surface of the top part 11. , and the nozzle pipe 19
A trigger 21 is hung from the rear of the front part, and a support plate 23 having a shape corresponding to the inner surface of the rear wall 12 on the head cap side is extended rearward from the rear of the hanging tube 20 to the outer surface of the rear wall 22. The lower portions of the left and right side walls of the plate 23 are pivotally attached to the inner surfaces of both the left and right walls of the cap body using pins 24, so that the plate 23 is assembled and stored in the head cap 2.

Therefore, if you grasp the head cap 2 and put your index finger on the trigger 21 and pull it,
The nozzle pipe 19 rotates counterclockwise about the pins 24, 24, and this rotation pushes the stem 9 downward, so that the discharge valve provided at the upper part of the container body 1 is opened and the container body is discharged. 1 internal liquid passes through the stem 9 and is sprayed from the nozzle hole 18 of the nozzle pipe 19. The nozzle hole 18 is shown as a separate nozzle hole member 25 made of a hard material.

Therefore, in the present invention, a locking plate 26 with a virgin seal function is provided on the upper surface of the top portion 11 of the cap body 14 to prevent the trigger 21 from being pulled.
That is, this locking plate 26 is coupled to the upper end of a branch 27 that rises from the upper surface of the nozzle pipe 19 and passes through the opening 16, and this branch 27 is severed when the trigger 21 is strongly pulled.

According to the present invention, the locking plate 26 with a virgin seal function is provided to prevent the trigger 21 from pulling and moving, and the spraying operation cannot be performed unless the locking plate 26 is removed. Unnecessary operations can be prevented before the product enters the market, and the reliability of the product can be improved. In this case, the locking plate 26 is provided on the upper surface of the nozzle pipe 19 and is not provided on the locus of movement of the nozzle pipe 19, so even if a part of the cut branch piece 27 remains, the nozzle pipe 19 can be pulled There will be no hindrance to movement. In addition, since spraying is performed by pulling the trigger 21 like a pistol, the spraying operation is easy.Furthermore, the head cap 2 and spray head 3 are shaped to fit within the outer shape of the container body 1, so they can be easily used for packaging, transportation, etc. It is advantageous for storage, etc.
