  Although this type of conventional aerosol device is premised on full amount injection upward, it can be said that it is preferable that the full amount injection of the insecticide for mites and fleas is performed at a relatively high concentration on the floor surface. Further, in the case of the upward injection type, in order to fill the whole area of a sealed room with a certain extent, it is assumed that it is set at the center of the room.

  In view of such a point, an object of the present invention is to provide a full-injection aerosol device that can inject laterally at a position close to a floor surface.

  In the present invention, in order to achieve this object, the injection button fitted at the base end portion to the valve stem protruding from the head of the aerosol container is constrained to the push-down operation position for driving the valve stem downward. According to the first aspect of the present invention, there is provided a full-amount-type aerosol device that injects the entire amount of the contents, and includes a long nozzle that communicates with the injection button and descends toward the bottom surface along the outer peripheral surface of the aerosol container. In addition, a horizontal spray port is formed at the lower end of the spray button, or a spray port for spraying forward is provided on the peripheral surface of the spray button, and the height from the bottom surface of the aerosol container to the head is provided. Is set to be lower than the diameter dimension of the aerosol container having a circular cross section.

  According to claim 1, in order to prevent the long nozzle from swinging during the pressing operation, the injection button projects from the mounting cup mounted on the head of the aerosol container. The injection button body is fitted to the valve stem at the base end and is pushed down, and the cover body is attached to the mounting cup and surrounds the periphery of the injection button. In addition to being integrally formed, the base end portion of the long nozzle is connected to the injection button via a flexible pipe.

  In order to ensure horizontal and horizontal injection regardless of movement of the injection port when the injection button is pushed down, according to claim 4, the injection button is attached to the valve stem protruding from the mounting cup mounted on the head of the aerosol container. The injection button body that is fitted at the base end and has a nozzle with a nozzle at the tip protruding sideways, and a cylindrical cover body that is mounted on the outer periphery of the mounting cup, and the nozzle covers It is connected to the upper end of the body via an integral hinge portion, and a lock portion is formed on the inner peripheral surface opposite to the nozzle of the cover body to constrain the outer peripheral surface of the injection button body. The main body is tilted downward in a normal state so as to face in a substantially horizontal direction in a state where the main body is tilted backward and is restrained by a lock portion at a pressing operation position.

  In order to facilitate the push-down operation of the spray button body in the backward state, the lever extending backward from the lock portion is attached to the spray button body and the spray button body is sprayed at a wide angle on a horizontal plane. According to claim 6, a plurality of injection ports are provided at intervals so as to make the horizontal injection angle a wide angle.

  According to the first aspect of the present invention, the long nozzle is sprayed laterally at a position close to the floor surface, and can be sprayed at a relatively high concentration against mites, fleas and the like on the floor surface. Compared to upward injection, it can be injected far away, and even if it is set at the corner of the room, it can be injected widely and effectively on the floor. In that case, according to the invention of claim 2, the long nozzle is integrally formed with the cover body attached to the mounting cup, so that the injection direction is stabilized without interlocking with the pressing operation. Appearance is improved by integration with the cover.

  According to the third aspect of the present invention, by spraying laterally from the vicinity of the head of the flat container, it is possible to spray along the floor surface at a position close to the floor surface. Even if set in the corner of the room, it can be sprayed widely and effectively on the floor. In this case, according to the fourth aspect, since the horizontally oriented nozzle is directed in the substantially horizontal direction during the push-down operation in the rearward state of the ejection button, it is avoided that the nozzle is ejected obliquely upward with the backward movement. Therefore, the injection in the direction along the floor surface is ensured.

  According to the fifth aspect of the present invention, the lever is attached to the injection button that is pushed down in the rearward state, so that the locking operation is facilitated, and it is possible to quickly go out of the room immediately after the pushing operation. According to the sixth aspect of the present invention, the wide nozzles of the horizontal direction are possible by dispersely arranging the long nozzles or the injection ports on the peripheral surface of the injection button, and even if set near the inlet by spreading widely to both sides. You can go out of the room quickly.
