Abstract

A rotary dispenser-type cosmetics container in which, when a button part rotates, guide protrusions move along a bottom surface of a pumping guide formed on an inner peripheral surface of the button part and then an ascending and descending member ascends and descends, whereby a pumping action is conducted. Therefore, the container discharges contents in a fixed state in which the height of the button part is not changed, and is thereby capable of preventing contents from unnecessarily leaking due to pressing a button by an external pressure.

First claim

What is claimed is:

1. A rotary dispenser-type cosmetics container comprising:
a container body wherein contents are held, further comprising a piston which ascends inside the container body according to the use of contents;
a housing which is combined to an upper portion of the container body, further comprising a contents inflow part forming a contents inflow hole at the center of a lower end of the housing so that contents contained in the container body flow in, and a multitude of vertical guide grooves formed along an outer circumferential surface with a fixed distance apart;
a button part combined to an upper portion of the housing to be rotatable, further comprising a rotation guide which forms a flexure portion upwards and downwards alternatively encasing an inner circumferential surface, and a discharging hole where contents are discharged on an upper end; and
an ascending and descending member which is ascended and descended by rotation of the button part, comprising a multitude of guide protrusions which move along a bottom surface of the rotation guide in a state of being inserted into the vertical guide groove and ascend and descend inside the vertical guide groove;
wherein at an inner surface of the button part is installed a combining tube which encases the discharging hole, thereby guiding the vertical movement of an ascending and descending member, and
wherein at the ascending and descending member is combined a contents movement tube which is combined to the combining tube and moves along an inner wall of the combining tube, forming a passage where contents move.

2. The rotary dispenser-type cosmetics container of claim 1 ,
wherein at an inner surface of an ascending and descending member is combined a piston rod which moves along together with movement of the ascending and descending member, and
wherein at a lower portion of the piston rod is combined a seal cap which closely encases an inner circumferential surface of the contents inflow part, thereby changing the pressure of an interior of the contents inflow part according to the ascent and descent of the piston rod and guiding contents held in the container body to flow into the interior of the contents inflow part.

3. The rotary dispenser-type cosmetics container of claim 1 , further comprising a combining ring which combines the button part to the housing so as to be rotatable.

4. The rotary dispenser-type cosmetics container of claim 1 ,
wherein at the discharging hole is combined a nozzle tip which is opened when contents are discharged, and at an inner circumferential surface of the discharging hole a multitude of support protrusions form a nozzle-tip combining hole and are protrusively combined with a fixed distance detached so as to support the nozzle tip.

5. The rotary dispenser-type cosmetics container of claim 4 ,
wherein the nozzle tip comprises an opening and closing plate which covers an upper end of the discharging hole, and a support bar which is extended from the center to the lower portion of the opening and closing plate and combined to the nozzle-tip combining hole, thereby supporting the opening and closing plate, and
wherein at a lower portion of the support bar is installed a fixing protrusion which encases an outer circumferential surface at a lower portion of the support bar, so as to prevent the nozzle tip from moving upwards and thereby being detached from the discharging hole.

6. The rotary dispenser-type cosmetics container of claim 5 ,
wherein an upper end of the fixing protrusion is positioned, detached from a lower end of the support protrusion, and then moves upwards by the pressure generated when contents are discharged, thereby meeting a lower end of the support protrusion.
