Abstract

Disclosed is a cosmetics container with a push button having a flexible upright nozzle in which a push button having an upright nozzle a discharge opening of which faces upwards is mounted to the cosmetics container such that the residual cosmetic contents left in the nozzle do not flow through the discharge opening and the flexible upright nozzle is easily bent during use thereof such that the discharge opening faces a lateral side. The cosmetics container includes: a container body filled with cosmetic contents and having a mouth; an airless pump mounted to the mouth of the container body to pump the cosmetic contents and having a discharge passage through which the cosmetic contents are discharged; and a shoulder for fixing the airless pump to the mouth of the container body and preventing leakage of the cosmetic contents from the container body, wherein a push button is coupled to the discharge passage of the airless passage, a nozzle is formed uprightly in the push button such that a discharge opening from which the cosmetic contents are discharged faces upwards, and the nozzle is formed of a flexible material.

First claim

What is claimed is:

1. A cosmetics container with a push button having a flexible upright nozzle, the cosmetics container comprising:
a container body ( 10 ) filled with cosmetic contents and having a mouth ( 16 );
an airless pump ( 20 ) mounted to the mouth of the container body to pump the cosmetic contents and having a discharge passage ( 22 ) through which the cosmetic contents are discharged; and
a shoulder ( 30 ) for fixing the airless pump ( 20 ) to the mouth of the container body and preventing leakage of the cosmetic contents from the container body,
wherein a push button ( 40 ) is circumferentially coupled to the discharge passage ( 22 ) of the airless pump ( 20 ), a nozzle ( 44 ) extends uprightly from an upper thickened portion of the push button ( 40 ) when the nozzle ( 44 ) is in an upright form, and the nozzle ( 44 ) is formed of a flexible material,
wherein boss rings ( 46 ) or bosses ( 48 ) are formed on surfaces of the nozzle ( 44 ) and the push button ( 40 ) such that a finger is not slid when the nozzle ( 44 ) and the push button ( 40 ) are pushed by the finger,
wherein the nozzle ( 44 ) in the upright form comprises a central vertical axis about which the nozzle ( 44 ) and push button ( 40 ) are axially symmetric and along which the discharge opening ( 42 ), the nozzle ( 44 ), the discharge passage ( 22 ) and the airless pump ( 20 ) are vertically coaxial,
wherein the cosmetic contents are discharged by pushing the nozzle ( 44 ) in any radial direction from the central vertical axis such that the nozzle ( 44 ) is bent and the discharge opening ( 42 ) faces a lateral side and further applying downward force on the nozzle ( 44 ) to push downward on the push button ( 40 ), and
wherein the nozzle ( 44 ) resiliently returns to the upright form when the nozzle ( 44 ) is released by the finger and the applied downward force is removed.

2. The cosmetics container of claim 1 , wherein the nozzle ( 44 ) and the push button ( 40 ) are formed of a same flexible material or only the nozzle ( 44 ) is formed of a flexible material and the push button ( 40 ) is formed by using an in-mold injection mold, and the nozzle and the push button are formed of different materials through a dual injection-molding method or the nozzle ( 44 ) and the push button ( 40 ) are separately injection-molded and then are assembled.

3. The cosmetics container of claim 2 , wherein the nozzle ( 44 ) is formed of one of nitrile rubber (NBR), natural rubber (NR), silicon rubber, and butadiene rubber (BR).

4. The cosmetics container of claim 1 , wherein the cosmetics container further comprises an inner container ( 12 ) having a cylindrical shape one side of which is opened, and a piston ( 14 ) that is coupled to the inner container ( 12 ).

5. The cosmetics container of claim 1 , wherein an auxiliary shoulder for easily coupling the airless pump is further provided between the shoulder ( 30 ) and the mouth ( 16 ) of the container body ( 10 ).

6. The cosmetics container of claim 1 , wherein a cover ( 50 ) for preventing introduction of foreign substances is coupled to the shoulder ( 30 ) to cover the button ( 40 ).

7. The cosmetics container of claim 1 , wherein the nozzle ( 44 ) is formed of one of nitrile rubber (NBR), natural rubber (NR), silicon rubber, and butadiene rubber (BR).
