Patent ID: 6923349

Claim:
A lotion bottle structure, comprising an outer sleeve tube, an upper control assembly, and a lower control assembly wherein the upper control assembly is mounted to the upper section of the outer sleeve tube, and the lower control assembly being adapted at the lower section of the outer sleeve tube therein; the present invention being characterized by that, the upper section of the outer sleeve tube, a hollow tubular sleeve, having a small-step coupling ring with engaging dots disposed thereon matching to an internal ring groove of a cover, a step-wise outer threaded section extending on top of the small-step coupling ring thereof, and an abutting stop sleeve with a sealing ring adapted thereon projecting on top of the step-wise outer thread section thereof; the upper control assembly mounted onto the upper section of the outer sleeve tube being made up of a sleeve valve, a mouthpiece, and a filter cap wherein the sleeve valve, having a projecting rod disposed at the top thereof, a tapered abutting facet with through holes thereon disposed at the middle section thereof, and a small-step sleeve part with a pair of symmetrical arc flexible plates and bottom flanges extending at the lower section thereof, is adapted to the top opening of the outer sleeve tube and sleeve joined thereto with the tapered abutting facet thereof located on top of the abutting stop sleeve thereof; the mouthpiece, having a tapered abutting nozzle with a central sleeve hole disposed at the top thereof, is screwed to the step-wise outer threaded section of the outer sleeve tube via an internal threaded section disposed at the inner bottom side and located thereto on top of the sleeve valve with the central sleeve hole thereof engaging with the projecting rod of the sleeve valve and the tapered abutting nozzle thereof closed tightly against the tapered abutting facet of the sleeve valve to seal up the through holes distributed at the tapered facet thereon; whereby, when the mouthpiece thereof is rotated to one side to unscrew the internal threaded section thereof from the step-wise outer threaded section thereof and detach the projecting rod of the sleeve valve from the central sleeve hole of the mouthpiece, a gap is formed at the tapered abutting facet of the sleeve valve and the tapered abutting nozzle of the mouthpiece there-between to reveal the through holes of the sleeve valve thereof for lotion to come out there-through and flow through the central sleeve hole of the mouthpiece to come out via the filter cap mounted on top of the mouthpiece thereof.
