BACKGROUND OF THE INVENTION
The present invention relates to a liquid ejection container with an aerosol can.
[0002]
[Prior art]
[Problems to be solved by the invention]
Aerosol-type liquid ejectors have been widely known and used in the past, but the liquid ejector has a stem that is urged by a pressing head fitted on the top of the stem that stands up through the top wall of the aerosol can. Then, the discharge valve provided at the lower end of the stem is opened and the liquid in the can is ejected from the nozzle of the above-mentioned depression head, so that other objects inadvertently touch the depression head. If pressed down, there is a risk of liquid ejection.
[0003]
Recently, two aerosol cans filled with different liquids are fastened together as a two-component mixing container, and one push-down head is fitted to the upper end of two standing stems. Some of these stems are lowered so that different types of liquid in each aerosol can are ejected together from a single nozzle of the push-down head. The amount of waste of liquid is likely to increase.
[0004]
The present invention is provided with a safety device with a simple configuration so as to prevent the above-mentioned wasteful liquid ejection.
