Patent ID: 8631975

Claim:
An airless pump comprising: a nozzle of a head, wherein content in a storage container is dispensed through the nozzle; a compression cylinder disposed between the storage container and the nozzle, wherein the compression cylinder has a compression chamber communicating with the storage container; a sealing cap fixing the compression cylinder; a piston valve and a piston fastened into the compression chamber inside the compression cylinder; an operation pipe disposed above the sealing cap in a direction perpendicular to a direction in which an operation button is pushed, wherein the operation pipe is actuated to move, thereby driving the piston and piston valve to move in the direction perpendicular to the direction in which the operation button is pushed; a spring disposed between the operation pipe and the sealing cap; and a slider axially coupled to the operation pipe in a direction perpendicular to the operation pipe, wherein the slider is actuated by the operation button to horizontally reciprocate in one direction, thereby driving the operation pipe in the direction perpendicular to the direction in which the operation button is pushed.
