## Abstract

The present invention relates to a nozzle structure of a dispenser pump button. According to the present invention, the nozzle structure of the dispenser pump button is designed in such a way that an outer nozzle with a discharge hole forwardly moves by the pressure of the content, and the content is discharged through the discharge hole distanced from an inner nozzle, thereby preventing the deformation of the nozzle. Therefore, the inflow of air into a cosmetic container is blocked, and thus the deterioration of the content can be prevented.

## Claims

### Claim 1

A nozzle structure of a dispenser pump button which is engaged to a discharge portion of a dispenser pump button for thereby discharging content to the outside, the nozzle structure comprising:
an inner nozzle which is formed in a cylindrical shape engaged to the discharge portion and has a plurality of content inflow holes formed at an end portion of a rear surface and spaced apart at regular intervals, and a blocking rod which forwardly protrudes from a center of the end portion of the rear surface;
an outer nozzle which includes:
a mounting part which is engaged surrounding the blocking rod, moves forwards and backwards, and is mounted at an end of an inner side of the inner nozzle; and
a content movement tube which forwardly extends from the center of the mounting part for thereby forming a passage through which the content moves, and has a discharge hole which is opened and closed by the blocking rod;
an elastic member which is engaged surrounding the outer nozzle and moves backwardly the outer nozzle; and
an elastic member fixing part which is engaged surrounding the inner nozzle at the inner side of the inner nozzle and has an elastic member mounting shoulder at which the elastic member is mounted in the inward direction, for thereby fixing one side of the elastic member,
wherein at an outer surface of the inner nozzle is formed an engaging protrusion fixed at the discharge portion, and at an inner surface is formed an engaging groove to which the elastic member fixing part is engaged.

### Claim 2 (depends on 1)

The structure of claim 1, wherein at the mounting part are provided a plurality of elastic member support parts which are spaced apart at regular intervals for thereby supporting the elastic member.

### Claim 3 (depends on 1)

The structure of claim 1, wherein at the elastic member fixing part is formed an engaging protrusion which corresponds to the engaging groove.

### Claim 4 (depends on 1)

The structure of claim 1, wherein the inner nozzle, the outer nozzle, the elastic member and the elastic member fixing part are integrated in a module type and are engaged to the engaging groove formed at the discharge portion through the engaging protrusion of the inner nozzle.

### Claim 5 (depends on 1)

The structure of claim 1, wherein at the inner surface of the inner nozzle is formed an engaging groove at which the elastic member fixing part is fixed, and at the elastic member fixing part is formed an engaging protrusion which is engaged to the engaging groove.

### Claim 6 (depends on 1)

The structure of claim 1, wherein at the end of the blocking rod is formed a protrusion which protruded towards the outside of the outer nozzle.
