BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a nozzle of an obliquely-handling valve which opens to permit the contents to be discharged when a stem constituting the aerosol valve is tilted. According to the present invention, the contents can be discharged without the need of forcibly pressing a stem of an obliquely-handling valve with thumb or the like from a side surface toward a tilted direction, but simply forefinger. That is, the aersol contents can be discharged easily by tilting the stem by pressing on a finger piece with the without requiring a strong pressure from the thumb or the like as in the past. Therefore, the aerosol contents can be continuously discharged for a relatively long period of time. The nozzle of the invention is particularly suitable for a high viscous contents, such as a caulking agent.
BACKGROUND ART
The contents of an aerosol have heretofore been discharged by pressing a stem of a obliquely-handling valve with the thumb or the liked from a side surface toward a tilted direction, or by pressing a nozzle which is connected to the stem. With this method, the nozzle or the stem must be pressed with the thumb or the like with a strong force, making it hard work to discharge the contents for a long period of time. If the obliquely-handling valve is so designed as to open without requiring a strong force, problems arise with regard to the air-tightness of the aerosol product, and also the aerosol contents may leak if an stem is touched by even a small force by mistake.
The object of the present invention is to provide a nozzle which enables the aerosol contents to be discharged continuously for a relatively long period of time without presenting problems from the standpoint of air-tightness or safety, and which can be opened easily yet requires a relatively large force for opening the obliquely-handling valve.
DISCLOSURE OF THE INVENTION
A fixing portion is provided at the lower end of a nozzle body so as to connect with, and secure the obliquely-handling valve of an aerosol vessel. A discharge path is formed from the fixing portion to a discharge portion of the aerosol contents. A finger piece for opening the obliquely-handling valve protrudes foldably from the side surface of the fixing portion by a thin folded portion. To discharge the aerosol contents, the user places a forefinger on the finger piece, and holds the aerosol vessel with the four other fingers. He then brings a discharge portion close to the target area, and press the finger piece with his forefinger toward the aerosol vessel. Due to the lever action, the obliquely-handling valve receives a strong force in an oblique direction and is opened. Therefore, the aerosol contents are discharged onto the target area from the discharge portion through the discharge path. Therefore, the aerosol contents can be discharged easily without requiring any strong force applied with the thumb or the like as in the past. That is, the aerosol contents can be discharged continuously for a relatively long period of time. This valve is particularly suitable for a high viscous contents such as a caulking agent.
After the discharging the aerosol contents is finished, the finger piece can be raised and engaged with an engagement portion provided on the outer periphery of the nozzle body. An engagement piece is formed on one surface of the finger piece to fix the finger piece to the outer side surface of the nozzle body. Therefore, after the finger piece has been used, the discharge portion can be covered with a cap or the like, the finger piece can be raised and pressed onto the outer side surface of the nozzle body. The engagement piece then engages with the engagement portion and is fixed parallel to the nozzle body, without protruding sideways from the nozzle body, thus making the valve convenient with regard to storage and transport. An over-cap or the like covering the nozzle body can also be fitted to the aerosol vessel.
