Abstract

The present invention relates to a cosmetic container capable of discharging two kinds of contents including a lower container body ( 200 ) for accommodating first and second containers ( 202, 203 ) which are coupled to a lower cap ( 201 ) and have cosmetic contents filled therein; airless pumps ( 300 ) including piston parts ( 301 ) provided in opening portions of the first and second containers ( 202, 203 ), and piston housings ( 303 ) provided on the outer periphery portions of the piston parts ( 301 ) and having pressing protrusions ( 302 ); button housings ( 400 ) for accommodating side buttons ( 500 ) which slide by pressing the pressing protrusions ( 302 ); and a mixture discharge member ( 700 ) which is coupled to the upper parts of the button housings ( 400 ) so as to discharge the cosmetic contents, and which is dented in a dish shape.

First claim

The invention claimed is:

1. A cosmetic container which is capable of storing and discharging two kinds of contents, the cosmetic container comprising:
a lower container body ( 200 ) coupled to a lower cap ( 201 ) in a lower part of the cosmetic container ( 100 ) to receive first and second containers ( 202 and 203 ) filled with cosmetic contents;
an airless pump ( 300 ) including a piston part ( 301 ) provided on opening parts of the first and second containers ( 202 and 203 ), and a piston housing ( 303 ) having a pressing protrusion ( 302 ) and provided on an outer periphery part of the piston part ( 301 );
a button housing ( 400 ) receiving a side button ( 500 ) which slides while pressing the pressing protrusion ( 302 ); and
a mixture discharge member ( 700 ) coupled to valve holes ( 402 ) for receiving a discharge valve ( 600 ) at an upper part of the button housing ( 400 ) to discharge cosmetic contents therethrough and concavely formed in a dish shape,
wherein the mixture discharge member ( 700 ) is provided with a discharge hole ( 701 ) through which the cosmetic contents are discharged by the airless pump ( 300 ) and the discharge hole ( 701 ) is provided with an opening/closing nozzle unit ( 702 ) which allows the cosmetic contents discharged at a discharge pressure by the airless pump ( 300 ) to be discharged at a low pressure,
wherein the discharge valve ( 600 ) narrows the flow path of the discharged cosmetic contents,
wherein a discharge rib ( 701 ′) formed on an inner periphery part of the discharge hole ( 701 ) keep in place the opening/closing nozzle unit ( 702 ) in the discharge hole ( 701 ) and prevents the opening/closing nozzle unit ( 702 ) from sliding out of the discharge hole ( 701 ) when the discharge pressure is applied, and
wherein the opening/closing nozzle unit ( 702 ) comprises:
a body piece wherein the discharge rib ( 701 ′) is in contact with the body piece to keep the opening/closing nozzle unit ( 702 ) in place within the discharge hole ( 701 );
a blocking piece ( 702 a ); and
an opening/closing wing piece ( 702 c ) wherein the opening/closing wing piece ( 702 c ) and the blocking piece ( 702 a ) are formed at opposite ends of the body piece and

wherein the blocking piece ( 702 a ) extends outwardly further than the body piece of the opening/closing nozzle unit ( 702 ) such that an outermost diameter of the blocking piece ( 702 a ) is substantially close to a diameter of the discharge hole ( 701 ) which acts as a chokepoint to the discharged cosmetic contents,
wherein the opening/closing wing piece ( 702 c ) extends outwardly further than the body piece of the opening/closing nozzle unit ( 702 ),
wherein a transfer hole ( 702 b ) is formed between the body piece of the opening/closing nozzle unit ( 702 ) and the inner periphery part of the discharge hole ( 701 ) to transfer the cosmetic contents wherein the cosmetic contents are in contact with the body piece and the inner periphery part of the discharge hole ( 701 ),
wherein the blocking piece ( 702 a ), the body piece and the opening/closing wing piece ( 702 c ) are constructed to be unitary structurally,
wherein the blocking piece ( 702 a ) allows transfer of the cosmetic contents to the transfer hole ( 702 b ) through the chokepoint,
wherein the transfer hole ( 702 b ) is constructed to have a length and a width greater than a distance between the outermost diameter of the blocking piece ( 702 a ) and the inner wall of the dispensing hole ( 701 ), and
wherein the opening/closing wing piece ( 702 c ) allows the cosmetic contents from the transfer hole ( 702 b ) to be discharged at a small quantity at low pressure.

2. The cosmetic container of claim 1 , wherein the opening/closing nozzle unit ( 702 ) is formed of an elastic material such that a discharge pressure of the cosmetic contents discharged by the airless pump ( 300 ) is reduced and the cosmetic contents are discharged through the discharge hole ( 701 ) at small quantity even under a low pressure.
