Abstract

A spray orifice structure for which, when spraying liquid contents onto a body part, such as a face, hair, an upper body or a lower body, by using a spray type container, it is possible to provide a user with a differentiated spray performance depending on each body part to be sprayed by manufacturing a spray orifice in consideration of an injection angle to which liquid contents are sprayed.

First claim

What is claimed is:

1. A spray orifice structure, the spray orifice structure coupled to a discharging part of a spray injection button to spray liquid contents to the outside, comprising an outer orifice coupled at the discharging part and forming an outer orifice which has an inner orifice insertion hole such that an inner orifice can be inserted therein,
wherein the outer orifice comprises a first injection hole which has a conical shape, formed with a diameter getting smaller from a distal end of the inner orifice insertion hole to a front end side thereof, and a second injection hole which extends from the front end side of the first injection hole and has a predetermined diameter and a predetermined length, such that an injection angle in which liquid contents are injected is determined by the proportion of the predetermined diameter and the predetermined length of the second injection hole,
wherein a fillet part with a rounded edge is formed at a circumference of a front end side of the second injection hole.

2. The spray orifice structure of claim 1 , wherein when the predetermined diameter and the predetermined length are set to 0.3 mm and 0.6 mm respectively, the injection angle is to be determined to 70°.

3. The spray orifice structure of claim 1 , wherein the injection angle is to be determined to 40° when the predetermined diameter and the predetermined length of the second injection hole are set respectively to 0.3 mm and 0.8 mm.

4. The spray orifice structure of claim 1 , wherein the fillet part has a rounded edge with a radius of 0.1 mm.
