Description

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

As is well known, in an aerosol sprayer, a liquid gas cylinder is built into a can containing liquid, and the internal pressure is increased by the atmospheric pressure of the liquefied gas.The atomizing head at the upper end of a stem protruding from the container body is pushed down. This opens the discharge valve and sprays pressurized liquid while the spray head is depressed. In this type of atomizer, the top surface of the atomizing head is usually open, and therefore, if the atomizing head is pushed down by accident or for some reason during the distribution process, liquid will be atomized and liquid will be wasted.

The present invention attempts to eliminate the above drawbacks by providing a virgin seal on the upper open surface of the spray head.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a can container body. This container body 1 is formed by wrapping the upper end of the body part 2 and the lower end of the tapered shoulder part 3 with a lower protrusion 4, and by wrapping the upper end of the shoulder part 3 and the periphery of the top wall 5 with an upper protrusion 6, and upper protrusion 6
A concave groove is provided just below.

A nozzle hole 8 is provided in the front at the upper end of a vertically movable stem 7 that protrudes liquid-tightly from the top wall 5 of the container body 1.
A spray head 9 with an open hole is connected and fitted through a hanging cylinder 7a. The spray head 9 is a rectangular block body long in the front and back direction, and has an operating lever 11 extending rearwardly on the upper surface of the head by a flexible hinge 10 on the rear side. In this case, as shown in FIGS. 3a and 3b, the rear upper surface of the spray head 9 is cut off by the thickness of the operating lever 11, and a recess 12 is formed in the center thereof, while the lower surface of the operating lever 11 is cut off. A member 13 that fits into the recess 12 is provided in a portion corresponding to the recess 12, and when the lever 11 is rotated from the solid line position where it is folded over the top surface of the head 9 to the operation position shown by the two-dot chain line, the operation lever 11 is moved to the spray head. It is designed so that it is flush with the upper surface of 9 and prevents the member 13 from fitting into the recess 12 and swinging. When the stem 7 is pushed down via the operating lever 11, a discharge valve provided in the upper part of the container body 1 opens, and the liquid in the container body 1 passes through the stem 7 and is sprayed from the nozzle hole 8 of the spray head.

Reference numeral 14 denotes a cylindrical head cap that surrounds the stem 7 and the spray head 9. A protrusion (not shown) on the inner periphery of the lower end of the head cap 14 is fitted into a groove directly below the upper protrusion 6, so that the head cap is raised higher than the spray head 9. It is erected from the container body 1. The head cap 14 has its front side cut off diagonally from the top to the middle, and its rear side cut off at the top so that there is no hindrance to spraying liquid from the nozzle hole 8 and pressing down the operating lever 11. Left and right facing walls 1 higher than head 9
The facing surfaces 5 and 16 are parallel vertical surfaces and serve as guide surfaces when the spray head 9 is raised and lowered. 17 indicates a handle.

In the head cap 14, a plate-shaped virgin seal is formed between the upper ends of the left and right opposing walls 15, 16 by several breakable connections 18, 18, so as to close the open surface above the spray head 9. 19 is installed.

That is, during the distribution process, the operating lever 11 is folded over the top surface of the spray head 9 as shown in FIG. Keep it. After breaking and removing the virgin seal 19, the consumer only has to open the operating lever 11 to the operating position as shown in FIG.

Incidentally, in the above, the spray head 9 can also be incorporated into the head cap 14 side as shown in FIG. In this case, the pins should protrude from both the left and right sides of the head 9, and the pins should protrude from both sides of the head 9.
The left and right facing walls 1 of the headcap 14 that guide the
A groove or a recess for engaging and guiding the pin may be provided vertically on the guide surfaces 5 and 16.

According to the present invention, a virgin seal 19 is provided on the upper open surface of the spray head 9, and spraying cannot be performed unless the virgin seal 19 is broken and removed. , operations caused by mischief etc. can be prevented, and the reliability of the product can be increased. Furthermore, since the spray head 9 is provided with an operating lever 11 that extends behind the head 9, it is possible to prevent the spray liquid from the nozzle hole 8 from leaking from the hand during operation.
