DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol container for spraying various liquid substances filled in a container in the form of a mist, in particular, cockroaches, termites, mites and other pests and rats that have entered a house. It is suitable for spraying various chemicals continuously and automatically for the time necessary to perform the operations such as extermination and disinfection sufficiently in order to exterminate or prevent the occurrence of sterilization and mold. It relates to an aerosol container.

[0002]

2. Description of the Related Art As a method for controlling indoor pests such as cockroaches, fleas, and mites, a method of directly or indirectly spraying a chemical having an insecticidal effect on pests to be controlled has been employed, and has been conventionally used. For example, a container containing an insecticide in the form of fumigation, which is widely known under the name of Barsan (registered trademark) or Earthlet (registered trademark), etc., and hermetically sealed and packaged in a canned container is used. I have been. The container containing these insecticides is allowed to emit smoke after opening the lid of the container in a closed room or the like, or the water is added to the container with the lid opened to cause a vaporization reaction. In other words, a method is employed in which insects are killed by filling the closed room with smoke of the generated insecticide and fumigation.

[0003] However, if these are used in a closed room, it is dangerous if humans, dogs, cats, and other animals inhale a certain amount of vaporized smoke. Requires strict caution, such as evacuation outside the room. In addition, since it is impossible to stop steaming with these types of containers in the middle, the components of the insecticide in the opened container must be used up to the end. Was wasted.

[0004] In order to eliminate such drawbacks and to make it possible to spray as much as needed at the place where the pests need to be exterminated when the extermination of the pests is required, JP-A-6-284846 and JP-A-8-26924 disclose the method. As seen in the official gazette and the like, a spray-type insecticide aerosol container in which an insecticide and a high-pressure propellant are sealed in a sealed container is known. The aerosol container as described above exerts a great effect in controlling pests,
Insufficient insect repellent effect can be maintained, and for mankind,
It is widely used because it has no danger in terms of toxicity and environmental pollution, and it does not matter if people come into contact directly or indirectly, and it can be used safely and easily. I have.

[0005] However, in order to control pests using these spray-type insecticide aerosol containers, a person must directly hold the aerosol container to perform spraying operation. The insecticide must be sprayed by constantly pressing the head, and even if it is harmless to the human body, if you continue to smell such a pesticide for a certain period of time, you will feel uncomfortable and feel bad Some people do.

Therefore, as an alternative to the above-described insecticide method, the insecticide can be continuously sprayed without relying on humans regardless of whether the insecticide is harmful or harmless to the human body. On the way, a spray container containing an insecticide capable of freely stopping the injection of the insecticide has been required. For example, a manual opening / closing valve as disclosed in JP-A-7-228503 has been demanded. A spray container containing an insecticide in the form of a pressure-resistant cylinder equipped with a gasket has been developed.

The above-mentioned spray container is a pressure-resistant container similar to the shape of a cylinder for high-pressure gas, and is attached to an opening of a container body so as to communicate between the inside and the outside of the pressure-resistant container. An on-off valve connected to a rotatable handle at an outer end of the inner pipe, the outer pipe having a space provided outside the inner pipe so as to cover the inner pipe; An injection port provided with a projection is provided, and a communication hole communicating with the inside of the inner tube is provided in a portion of the inner tube inside the container, which is slightly above the opening at the tip thereof, and further, The outer tube is provided with a communication hole to form an aerosol container.

The aerosol container having the above structure is filled with a pressurized propellant, such as carbon dioxide gas or petroleum gas, together with an insecticide or disinfectant that requires spraying. After the container is transported to a place where insecticide or sterilization is required, place the container in an appropriate place, twist the handle, and open the valve. The spray can be continuously performed, and the spray can be interrupted at any time by twisting the handle in the direction in which the valve closes.

The above-mentioned aerosol-type spray container for insecticides or the like is capable of freely selecting continuous spraying and stopping the spraying, and is convenient because the contents can be refilled. However, on the other hand, the manufacturing cost of the container is high, and the shape of the container body is slightly large, and it is difficult to mold it into a small and lightweight one that can be held by one hand. Although suitable for a large-capacity spray container to be used, it was unsuitable for a small-capacity spray container used in ordinary households.

Therefore, the applicant can solve the above-mentioned various problems and continuously and automatically spray a liquid substance such as an insecticide or a disinfectant. An application has already been filed for the invention of a small and lightweight aerosol container which can be interrupted.

As shown in FIG. 6, the present invention relates to an aerosol container in which an injection pipe and an injection head are provided in a pressure-resistant sealed container filled with a liquid material to be injected and a propellant to be pressurized so as to be jettable. An opening 25c that fits with the injection pipe 24 is provided on a cylindrical support frame 28 that is fitted and fixed to the shoulder 22a of the container so as to surround the injection pipe that protrudes from the opening end 23 of the container body 22. A pressing operation member 28 in which a spherical upper surface member 26 having an injection groove 26a formed on a lower surface member 25 having an annular flat pressing operation surface 25b on the outer peripheral surface of a bowl-shaped spherical member 25a is overlapped with the injection pipe. The injection head is formed so as to be able to advance and retreat so as to fit with the nozzle 24 to form an aerosol container.

The aerosol type spray container having such a structure can be freely selected between continuous spraying and suspension of spraying, and can be formed into a small and lightweight one which can be held by one hand. However, on the other hand, the pressing operation member that forms the ejection head on the other hand is attached to the periphery of the hemispherical member of the upper surface member formed so as to match the inner peripheral surface of the spherical portion of the lower surface member. A fitting portion is provided for fitting to the protruding peripheral edge of the semi-spherical portion of the member, and the fitting portion is provided with an annular ejection path communicating with an end of the concave groove and an ejection hole communicating with the ejection path. Since it is formed, it has a disadvantage that the production cost of the container is high due to its complexity.
