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, and particularly for controlling cockroaches, termites, mites and other pests that have entered a house. The present invention relates to an aerosol container suitable for automatically spraying a pesticide continuously for a required time in order to achieve the above.

[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), and is hermetically sealed in a canned container, is used. I have been. The container containing these insecticides is allowed to emit smoke after the lid of the container is opened in a closed room or the like, or vaporization reaction is performed by adding water to the container with the lid opened. 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 disclosed in the official gazette and the like, there is a spray-type insecticide aerosol container in which an insecticide and a high-pressure propellant are sealed in a sealed container. They exert a great effect in controlling pests, can maintain a sufficient insect repellent effect, and have no danger to humans in terms of toxicity and environmental pollution, and can be directly or directly controlled by humans. Indirect contact does not pose a problem and is widely used in general because it can be used safely and easily.

[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.

[0007] As shown in Fig. 3, the spray container containing the insecticide is a container for allowing the inside and outside of the pressure-resistant container to communicate with the main body 21 of the pressure-resistant container, which is similar to a high-pressure gas cylinder. An inner pipe 22 for pouring attached to the mouth of the main body, and an outer pipe 23 joined to cover the inner pipe by providing a space p outside the inner pipe. A rotatable handle portion 24 at the outer end of the container, a valve seat portion 25 provided with an on-off valve connected to the handle, and an injection port 26 protruding from the valve seat portion. , The inner tube 2
An opening end 22a is provided at the tip of the inner part of the container 2 and a communication hole 22b communicating with the inside of the inner tube is provided at a part slightly above the opening end. The tube 23 is provided with a communication hole 23a communicating with the space p to constitute an aerosol container.

In the aerosol container constructed as described above, the handle 24 is rotated to open the on-off valve, and then a predetermined insecticide f is injected into the inside thereof.
An aerosol product that can be sprayed such as a pesticide is filled by filling a pressure propellant such as liquefied carbon dioxide gas, chlorofluorocarbon gas, or petroleum gas and then closing the on-off valve. After the insecticide spray container having such a configuration is transported to a place where pesticide is required, if the container is properly installed and the handle is opened to open the valve, the pressure of the propellant causes the insecticide to be sprayed. Spraying can be continuously performed from the injection port, and spraying can be stopped at any time by twisting the handle in the direction in which the valve closes.

The aerosol spray container containing such an insecticide or the like is capable of freely stopping continuous spraying and spraying, and is also capable of refilling the content liquid. Manufacturing costs are high, and it is difficult to mold the container body into a small size that can be held with one hand, and it must be somewhat large and heavy. Although suitable for a spray container, it is not suitable for a small-capacity spray container for general households.
