Description

[Detailed Description of the Invention] This invention relates to a sprayer that sucks up liquid contained in a liquid storage means such as a container into a cylinder by sliding a piston and sprays it out under pressure.

Most known sprayers are configured to pressurize and spray liquid within a cylinder by lowering a piston as a lever rotates.

Therefore, it is necessary not only to package and transport the lever carefully so that it does not rotate when not in use, but also to prevent the lever from turning due to carelessness, falling, or mischief by children when displayed at a store. It is necessary to take measures to prevent liquid from spewing out due to rotation.

The purpose of this invention is to provide a sprayer that prevents liquid from being sprayed out due to inadvertent turning of the lever during packaging, display, etc.

An embodiment of this invention will be described in detail below with reference to the drawings.

As shown in FIG. 1, a sprayer 10 according to the present invention, like the sprayer previously filed by the applicant, is connected to a container 14 by a tightening cap 12 and has a vent hole 16 bored in its side wall. The sprayer body 18 includes a sprayer main body 18, and an elastic cylinder 20 that is placed in close contact with the inner wall of the main body and closes a ventilation hole.

An actuating rod 22 that is connected to a lever (not shown) directly or indirectly through a piston pivotally mounted to the lever and is pulled and pulled in cooperation with the lever is connected to the elastic cylinder 20 through the ventilation hole 16. The elastic cylinder is arranged so as to elastically deform the elastic cylinder when it comes into contact with the elastic cylinder.

Due to the elastic deformation of the elastic cylindrical body, outside air flows into the container 14 through the ventilation hole 16, thereby preventing negative pressure inside the container.

Since the actuating rod 22 operates in cooperation with the lever, rotation of the lever can be hindered by restricting the movement of the actuating rod.

Therefore, in order to prevent unnecessary rotation of the lever, it is sufficient to restrict the movement of the actuating rod 22.

Therefore, the sprayer 10 according to the present invention further includes a safety seal 24 integrally formed with the actuating rod 22 to prevent the actuating rod from coming into contact with the elastic cylinder 20.

This safety seal 24 is removably connected to the actuating rod 22 via a connecting portion gate 26.

As can be clearly seen from FIG. 2, the safety seal 24 is disposed in front of the actuating rod 22 and has a blocking portion 2 that blocks its path.
8, a fulcrum part 30 located on the opposite side of the obstructing part with respect to the gate 26 and forming a fulcrum 29 during peeling; It is integrally provided with an extending engagement portion 32 to be fitted.

The baffle part 28 includes a fitting guide hole 28a for preventing the tip of the actuating rod 22 from shifting laterally, and a protruding guide piece 28b for preventing the safety seal 24 itself from shifting. It has

The sprayer 10 of this invention is constructed as described above, and the movement of the actuating rod 22 is prevented by the baffle 28 of the safety seal 24 disposed adjacent to the vent hole 18, so that the atomizer 10 is constructed in cooperation with the actuating rod. The lever cannot be rotated.

Therefore, unnecessary rotation of the lever during packaging, display, etc. is completely prevented.

When using the case, if the extending engagement portion 32 is rotated in the direction of arrow A around the gate 26, the fulcrum 29 will come into contact with the actuating rod 22. This principle will cause a large peeling force to be applied to the gate 26. As a result, the gate is broken and the safety seal 24 is easily separated from the operating rod.

Here, in order to facilitate the breakage of the gate 26, it is preferable that the gate has an acute constriction on the side of the baffle part.

According to this invention, by providing a safety seal, it is possible to completely prevent the rotation of the lever and the ejection of dangerous liquid when not in use, and when necessary, the safety seal can be peeled off easily and quickly. In addition to being able to perform a jetting operation, the presence of a safety seal can also be used as a selling point and can increase the product value.

Claims (3)

[Scope of utility model registration request] (1) A ventilation hole is formed in the side wall of the liquid sprayer body connected to the container, and an elastic cylinder that closes this ventilation hole is placed in close contact with the inner wall of the main body, and when pulled together with the lever, the elastic cylinder An actuating rod is disposed in cooperation with the lever and is interposed between the actuating rod and the elastic cylinder to communicate between the vent hole and the inside of the container by contacting the cylinder and elastically deforming the elastic cylinder. This sprayer is integrally molded with the actuating rod so that it can be peeled off as a safety seal and has a blocking part that prevents the actuating rod from coming into contact with the elastic cylindrical body through the ventilation hole. (2) The safety seal is located on the side opposite to the obstructing part side with respect to the operating rod stop connecting part and the oricate, and serves as a fulcrum part that forms a fulcrum during peeling, and the safety seal is useful for peeling by rotating around the fulcrum. The sprayer according to claim 1, wherein the extending retaining portion is integrally provided with the baffle portion. (3) The sprayer according to claim 2, wherein the gate of the safety seal has an acute constriction on the side of the obstructing part.
