Abstract

Abstract The disclosure relates to a manually operative atomizer in which a liquid is sucked and pressurized by an atomizer means and is then atomized through a nozzle port. A chamber for pressurizing the liquid is constituted by a cylinder, while an atomizer head is connected to a communication pipe which plays also the role of a piston, and is biased in the direction reverse to the pressurizing direction, by means of a spring. The atomizer head is provided with a guiding member adapted to be pressed and moved by an inclined surface of the operation member, so that the atomizer head and the piston or the jetting pipe are moved in the pressurizing direction. As the operation member is released from the depressing force, the spring moves the member back to its original position. Portions of the periphery of the atomizer head other than the nozzle port and the operating portion of the operating member are covered by a cap.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 242 words
In a manually operable atomizer of the type having a container for containing liquid and an atomizer assembly connected to said container for atomizing the liquid, the atomizer assembly including a cylinder, a piston slidable in said cylinder, an atomizer head having a nozzle port therein, a pipe connecting and allowing communication between said piston and said atomizer head, and a spring biasing said atomizer head in a first direction, movement of said atomizer head in a direction opposite said first direction causing compression of liquid in said cylinder, forcing the liquid through said pipe and out through said nozzle port, the improvement comprising: a guiding member on said atomizer head; an operating member for depressing said guiding member against the biasing of said spring, said operating member including an inclined surface engaging said guiding member; and a cap connected to said container for supporting said operating member, said cap having openings therein for allowing access to said operating member and to allow passage of the atomized liquid; said guide member being in the form of a pair of guide pins projecting outwardly from respective side surfaces of said atomizer head; said inclined surface of said operating member including corresponding inclined cam surfaces on two space arms of said operating member, said cam surfaces engaging respective ones of said guide pins; said operating member being pivotally secured at a base portion thereof to the ceiling of said cap for free pivotal movement.
Claim 2
Dependent Claim 242 words
In a manually operable atomizer of the type having a container for containing liquid and an atomizer assembly connected to said container for atomizing the liquid, the atomizer assembly including a cylinder, a piston slidable in said cylinder, an atomizer head having a nozzle port therein, a pipe connecting and allowing communication between said piston and said atomizer head, and a spring biasing said atomizer head in a first direction, movement of said atomizer head in a direction opposite said first direction causing compression of liquid in said cylinder, forcing the liquid through said pipe and out through said nozzle port, the improvement comprising: a guiding member on said atomizer head; an operating member for depressing said guiding member against the biasing of said spring, said operating member including an inclined surface engaging said guiding member; and a cap connected to said container for supporting said operating member, said cap having openings therein for allowing access to said operating member and to allow passage of the atomized liquid; said guide member being in the form of a pair of guide pins projecting outwardly from respective side surfaces of said atomizer head; said inclined surface of said operating member including corresponding inclined cam surfaces on two space arms of said operating member, said cam surfaces engaging respective ones of said guide pins; said operating member being pivotally secured at a base portion thereof to the ceiling of said cap for free pivotal movement.
Claim 3
Dependent Claim 22 words
A manually operable atomizer as claimed in claim 1, wherein said operating member includes a trigger section on a lower portion thereof.
Claim 4
Dependent Claim 14 words
A manually operatable atomizer as claimed in claim 1, wherein said cap is detachable.
