Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an insecticide container in which a room is sealed and an insecticide is sprayed inside the sealed room.

"Prior Art" An aerosol container is used as the insecticide container. The container has a push-down button attached to the stem that penetrates the top wall of the container and stands up in an upwardly biased state, and the push-down state of the stem is maintained by fitting the button into the upper part of the push-down container body. , the insecticide inside the container was spouted out at the same time as the forked stem was pressed down.

``Problem to be solved by the invention'' Since the conventional insecticide container described above was installed so that the insecticide was sprayed at the same time as the container was set, it was possible for the person setting the container to spray the insecticide to some extent before leaving the sealed room after setting the container. I ended up inhaling it, which was not desirable.

The present invention eliminates the above-mentioned drawbacks and eliminates the risk of inhaling the insecticide by starting the spraying after a predetermined period of time has elapsed after setting.

"Means for Solving the Problems" A valve box 9 is fixed to the back surface of a top wall 8 that airtightly closes the mouth of the container, and an outflow pipe 10 is suspended from inside the valve box to the bottom of the container, and the valve In an aerosol type insecticide container in which the stem 11 is erected in an upwardly biased state by penetrating the top wall 8 from inside the box, the partition plate 12 is fitted into the lower part of the container body 2 in a watertight manner and can be lowered. Then, the inside of the body below the partition plate is formed into a first chamber 13 filled with a high-pressure harmless propellant, and the inside of the upper body is formed into a second chamber 14 filled with a high-pressure insecticidal propellant, and the partition plate is made watertight. The lower end of the outflow pipe 10 is inserted into the first chamber 13 by slidingly passing through the outlet pipe 10.
A hole is opened inward, and the stem 11 has a stem push-down position in which the state in which the stem is pushed down to the injection position against bias is held by direct or indirect engagement with the container body. A holding device was attached.

``Operation'' From the state shown in Figure 1, cap 2 is attached to container body 1.
8 and push down the stem 11, the discharge valve inside the valve box 9 opens, and the first chamber 1 below the partition plate 12 opens.
A harmless high-pressure propellant filled in the valve body 3 is discharged from the outflow pipe 10 hanging from the valve body, the valve body 9, and the stem 1.
1 and is discharged to the outside of the container body. Due to the discharge, the pressure inside the second chamber 14 above the partition plate 12 becomes higher than that in the first chamber, so that the partition plate 12 is lowered and the lower end of the outflow pipe 10 opens into the second chamber, so that the second chamber 14 above the partition plate 12 becomes higher in pressure than the first chamber.
The high-pressure insecticide propellant in the room is ejected outside the container.

"Example" 1 is a container body in which a mouth part 4 is made to stand up from the upper end of a body part 2 via a shoulder part 3, and a downward step part 5 is formed between the lower part and the middle part of the body part of the container body. The lower portion of the step is formed into a large diameter portion 2a. 6 is the bottom wall,
A rubber stopper 7 serving as a gas filling port is fitted into the center of the bottom wall. 8 seals the mouth of the container with the top wall of the container. A valve box 9 is fixed to the back surface of the central part of the top wall, and an outflow pipe 10 is vertically installed from the valve box, and a stem 11 is inserted upward from inside the valve box 9 by penetrating the top wall 8. It is standing upright.

Normally, the discharge valve in the valve box opens by pushing the stem down against the valve box 9, and then the high-pressure insecticide propellant inside the container is ejected from the stem 11 through the outflow pipe 10, etc. Aerosol insecticide containers of this construction are known.

In this case, a partition plate 12 is provided in the body part 2 by engaging the upper surface of the outer periphery with the lower surface of the downward step part 5 mentioned above, and a first chamber 13 filled with a high-pressure harmless propellant is provided inside the body part below the partition plate.
Moreover, the inside of the body above the partition plate is a second chamber 14 filled with a high-pressure insecticide propellant. The outer peripheral surface of the partition plate can be lowered while remaining in airtight contact with the inner wall surface of the body, and the lower part of the aforementioned outflow pipe 10 is passed through the partition plate 12 in an airtight manner, and the lower end of the pipe is inserted into the first chamber 13. Open the hole. Note that 15 is an O-ring.

The above-mentioned stem 11 is attached with a device that holds the stem pressed down to the injection position against the bias by direct or indirect engagement with the container body. The device may be the push-down button described above, but in the illustrated example, when the cap 28 is turned relative to the container body 1,
The stem 11 is pushed down via the actuating member 22, and the pushed down state is maintained.

The illustrated device will be explained.

A top wall 17 of the fitting cylinder 16 is provided on the outer surface of the mouth of the container body.
A cylindrical portion 18 extending vertically from the back surface is fitted in a non-rotatable manner. As shown in FIG. 2, the fitting tube 16 has a top wall 17 with an open central portion, and a guide tube 20 with a plurality of grooves 19 vertically arranged on the inner surface thereof stands up from the inner circumferential edge thereof, and a guide tube 20 with a plurality of grooves 19 vertically disposed on the inner surface of the fitting tube 16 is opened from the outer circumference of the top wall. A tube 21 is installed vertically.

Inside the guide tube 20, there is a tube portion 2 of the actuating member 22.
3 are fitted together so that they can move up and down. The cylindrical part has a plurality of vertically disposed protrusions 24 on its outer surface that move up and down in the groove, and the small cylinder 26 is held by a plurality of support plates 25 that protrude from the inner surface of the cylindrical part toward the center of the cylindrical part. Then, the upper part of the stem 11 described above is fitted into the small cylinder. A downward step 27 is provided on the inner surface of the small cylinder, and the upper end surface of the stem is engaged with the lower surface of the step so that the stem is pushed down when the actuating member 22 is pushed down.

Reference numeral 28 denotes a cap, and an outer circumferential wall 30 extending vertically from the outer periphery of the cap top wall 29 is rotatably fitted to the outer surface of the outer cylinder 21 of the aforementioned fitting cylinder 16. An opening 31 is formed in the opening 31, and a small cylinder 26 of the actuating member is loosely inserted into the opening. Also, as shown in Figure 2, from the top wall of the cap are the cam plates 32,
32 vertically and by rotating the cap 28 with respect to the container body, the upper edge of the support plate 25 of the actuating member 22 comes into contact with the inclined surfaces 33, 33 of the cam plate, and the actuating member is pushed down. 11 are pressed down together to eject the harmless propellant in the first chamber 13 of the container body.

``Effect of the invention'' Since the present invention has a structure that has the effect described above, the first
After the high-pressure harmless propellant in the chamber 13 is released, the insecticide will be sprayed out after a predetermined period of time, and the person who set it will be able to evacuate from the sealed chamber before the insecticide spray starts. , thus preventing the risk of inhaling pesticides. Further, a partition plate 12 is provided in the container body, and the lower part of the partition plate is used as a first chamber, and the upper part of the partition plate is used as a second chamber. Since the plate is lowered so that the lower end of the outflow pipe 10 opens into the second chamber and the high-pressure insecticidal propellant in the second chamber is spouted out, its operation can be ensured.
