Abstract:
1. An airless type cosmetics vessel comprising: a discharge cap mounted to the vessel body and defining a discharge passage therein and receiving a control nozzle in the discharge passage, a push button placed in the discharge cap so as to move upwards and downwards and elastically biased upwards by a compression spring, a cylinder mounted to the discharge cap, a piston unit axially connected to the push button and being movable upwards or downwards so as to suck a cosmetic from the vessel body into the cylinder and to discharge the cosmetic from the cylinder through the discharge passage, and a cylinder bushing mounted to the discharge cap and receiving the cylinder therein and defining a guide passage communicating with the discharge passage and having a cosmetic inlet port in a lower end thereof, wherein the discharge cap comprises: an outer cap part and an inner cap part placed inside the outer cap part, wherein the control nozzle is installed both through the nozzle installation hole and through the airtight nozzle hole such that the control nozzle reaches the button seat; and the piston unit comprises: a piston rod connected to a coupling pipe coupled to the push button; and a piston coupled to the piston rod and moved upwards and downwards between the coupling pipe and the piston rod, wherein the piston rod movably receives therein an axial valve, the axial valve comprising a valve stem and a valve body provided at a lower end of the valve stem so as to open or close the guide passage, wherein when the push button is moved upwards, the axial valve is primarily moved upwards, so that the valve body closes the guide passage and, at the same time, opens the cosmetic inlet port of the cylinder bushing, and the piston rod is secondarily moved upwards, thus sucking the cosmetic into a cylinder chamber; and when the push button is pushed downwards, the axial valve is moved downwards, so that the valve body closes the cosmetic inlet port of the cylinder bushing and opens the guide passage, and the piston rod is secondarily moved downwards, so that the piston coupled to the piston rod compresses the cylinder chamber and the cosmetic is discharged from the cylinder chamber through the discharge passage after passing through the guide passage and the discharge passage.
