Description

  The present invention relates to a foot-operated liquid ejecting apparatus, and in particular, to provide a foot-operated liquid ejecting apparatus using a pump-type dispenser as a discharge mechanism.

  Conventionally, as a stepping type liquid ejecting apparatus, an aerosol type container as described in Patent Document 1 is mainly used. However, aerosol-type containers sometimes contain propellants such as flammable liquefied petroleum gas or dimethyl ether, and if they are discarded with the gas remaining in the container, they are used in garbage collection vehicles and waste disposal facilities. May cause fire or explosion. In order to prevent such an accident, when an aerosol-type container is to be discarded, it is necessary to discharge the residual gas inside the container, which is troublesome. In addition, the aerosol-type container uses the pressure of the gas filled in the container to inject the content liquid, so the content liquid continues to come out while the injection button is pressed, and the injection amount is controlled. In an aerosol-type container, proper ejection is not performed due to insufficient pushing of the stem that may occur when the liquid content is ejected, and a large amount of propellant is ejected from the internal solution. In such a case, the pressure of the filled gas is insufficient, and there is a problem that the liquid content remains in the container and cannot be used (the remaining amount increases).

  For this reason, there is a demand for a stepping type liquid ejecting apparatus using a pump type (accumulation type) dispenser instead of aerosol as a discharge mechanism. According to the pump-type dispenser, there is no need for a propellant for pressurization like an aerosol-type liquid ejection device, and there is no danger of explosion at the time of disposal of the container. In addition, since there is no problem that the content liquid cannot be discharged due to insufficient gas pressure, the remaining amount remaining in the container without being ejected can be reduced, and a pump-type dispenser Since the content liquid can be ejected by one-pushing the pressing head, it is possible to discharge the liquid quantitatively.
