Description

[0001] SPRAY APPARATUS [0002]

The present invention relates to an injection device.

The aerosol spray may include a pressure vessel having an opening, a cap disposed at an opening of the pressure vessel, a stem coupled to the cap and protruding outwardly, and a presser coupled to the stem to press the stem to open the valve And a spraying device including a spraying portion.

In the pressure vessel of the aerosol spray as described above, a gas for injecting the jetting substance and the jetting substance is charged according to the purpose of use. The inside of the pressure vessel filled with the jet and the gas maintains the state where the internal pressure is applied by the vapor pressure of the gas. When the user directly presses the pushing part of the injection device, the stomach is opened and the jet and the gas are simultaneously sprayed.

The amount of jetting of the jet and the gas depends on the pressure the user presses on the pushing part. If a large amount of spray is required, the presser foot must be pressed hard. In case of precise (fine) spraying of the jet on the jetting area during the precision work, the pressing part should be gently pressed. However, the pushing force can not be pressed constantly by the force of the user. That is, while pressing the pressing part, the pressing force of the pressing part is changed by the user, and the precision work is deteriorated because the jet is not continuously sprayed.
