Description:
BACKGROUND 
       [0001]    Generally, when a user pushes a spray injection button, spray containers spray liquid contents in a container into a spray state, and are widely used in cosmetics or medicines. 
         [0002]    Among these types of spray containers, “Sprayer (Korean Patent Laid-Open Publication No. 2000-0049441)” of the following Patent Document 1 is an ordinary spray device, having an advantage in that by equipping a tube case having a suction hole and a ball for controlling the suction hole, and a double tube suction device composed of an inner case and a tube, it is possible to spray liquid contents even when the spray container is upside down. In addition, the shapes of a second valve and a housing thereof have been improved, such that both parts are always in contact with each other, it is possible to prevent the degradation of spray performance which arises during the spray due to the deformation of the second valve. 
         [0003]    However, “Sprayer” of the Patent Document 1 does not indicate a separate structural figures and shapes for a discharging space in a process that liquid contents stored inside a container body are being sprayed through a nozzle by pressurizing a button. Due to this, an injection angel which is the most important among the elements of spray containers is not structured in the best fit for using according to its purpose, such that it is not possible to provide the best spray performance for each body part. 
       SUMMARY OF THE DISCLOSURE 
       [0004]    The present disclosure relates to a spray orifice structure, the spray orifice structure  1  coupled to a discharging part  11  of a spray injection button  10  to spray liquid contents to the outside.

     DETAILED DESCRIPTION 
       [0014]    Hereafter, a spray orifice structure will be described in detail according to exemplary embodiments with reference to the accompanying drawings. First, in the drawings, it is to be noted that the same elements or parts are denoted by the same reference numerals whenever possible. In the description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as not to obscure the subject matter of the present invention. 
         [0015]    The presently described embodiments, as illustrated in  FIG. 4 , comprise largely an outer orifice  100  and an inner orifice  200 . 
         [0016]    Prior to further explanation, it should be noted that for the sake of clarity, referring to  FIG. 2 , a left side of the element is referred to as a front end side and a right side is referred to as a distal end side. 
         [0017]    Firstly, an outer orifice  100  will be explained. The orifice  100 , as illustrated in  FIGS. 1 and 2 , is an element which is coupled to a discharging part  11  of a spray injection button  10  and sprays liquid contents stored inside a container body (not illustrated) into small particles like mist, further comprising an inner orifice insertion hole  110 , a first injection hole  120 , and a second injection hole  130 . 
         [0018]    The inner orifice insertion hole  110 , as illustrated in  FIG. 1 , is an element formed as a space at an inner side of the outer orifice  100 , where an inner orifice  200  is inserted. 
         [0019]    The first injection hole  120 , as illustrated in  FIGS. 2 and 3 , is a kind of a content movement passage formed with a diameter gradually decreasing to a direction of liquid contents being sprayed at one side of the inner orifice insertion hole  110 . 
         [0020]    In other words, a front end side is formed to have a smaller diameter than a distal end side. 
         [0021]    Due to such a structure, in a process of being moved from a distal end side of the first injection hole  120  to a front end side of the first injection hole  120 , liquid contents flowing into a distal end of the first injection hole  120  are compressed as moving more closely toward the first injection hole  120 , thereby making the pressure of the front end side of the first injection hole  120  bigger and causing liquid contents to be turned into fine particles as mist. 
         [0022]    The second injection hole  130 , as illustrated in  FIGS. 3 and 4 , is a contents spray passage which is formed, perforated to a direction of liquid contents being sprayed at a front end side of the first injection hole  120 . The second injection hole  130  is formed with a predetermined diameter (Φ) and a predetermined length (L), such that an injection angle in which liquid contents are sprayed is possible to be determined by a proportion of the diameter (Φ) and the length (L) of the second injection hole  130 . 
         [0023]    Herefrom, the bigger diameter (Φ) the second injection hole  130  forms, the bigger the cross section area of the second injection hole  130  becomes, such that a sprayed amount of liquid contents passing through the first injection hole  120  increases. The smaller the diameter of the second injection hole  130  gets, the more decreased the cross section of the second injection hole becomes, such that a sprayed amount of liquid contents passing through the first injection hole  120  decreases. 
         [0024]    Furthermore, as a length (L) of the second injection hole  130  gets longer, a distance that liquid contents have to move becomes longer, such that an inner pressure of the second injection hole  130  gets reduced in a process that liquid contents pass through the second injection hole  130 , and thereby spraying pressure becomes reduced. On the contrary, as a length of the second injection hole  130  is formed shorter, a distance that liquid contents have to move becomes shorter, such that an inner pressure of the second injection hole  130  gets increased in a process that liquid contents pass through the second injection hole  130 , and thereby spraying pressure becomes increased. 
         [0025]    An injection angle (K) is determined based on the relationship between the diameter (Φ) and the length (L) of the second injection hole  130 . When the diameter (Φ) and the length (L) are set to 0.3 mm and 0.6 mm respectively, the injection angle (K) will be determined to 70° whereas the injection angle (K) will be determined to 40° when the diameter (Φ) and the length (L) of the second injection hole  130  are set respectively to 0.3 mm and 0.8 mm. 
         [0026]    In this case, to respectively secure an injection angle (K) from the length (L) of the second injection hole  130  formed with a short length, a fillet part  131  with an edge rounded is formed at a circumference of a front end side of the second injection hole  130 , wherein the fillet part  131  is preferred to have a rounded edge with a radius of 0.1 mm. 
         [0027]    A spray orifice structure  1  with an injection angle (K) of 70° is best fit for applying liquid contents onto a facial surface because the injection angle is wide, whereas a spray orifice structure  1  with an injection angle (K) of 40° is best fit for applying liquid contents onto body parts, arms, or legs because the injection angle (K) is narrow. 
         [0028]    Meanwhile, it is preferred that at an outer circumferential surface of the outer orifice  100  are formed one or more coupling protrusions  132  so as to be fixed to the discharging part  11 , and that at the discharging part  11  is formed one or more coupling grooves  11   a  so that the coupling protrusions  132  can be coupled therein. 
         [0029]    Due to the configuration as the above, the outer orifice  100  can be easily assembled to or detached from the spray injection button  10 , such that it is possible to change the outer orifice  100  and the inner orifice  200  with ease and to assemble and examine the outer orifice  100  and the inner orifice  200  individually in a process of manufacturing, thereby leading to lowering defective rate and improving productivity. 
         [0030]    Next, an outer orifice  200  will be explained. The inner orifice  200 , as illustrated in  FIGS. 1 and 2 , is inserted to the inner orifice insertion hole  110  and coupled to the outer orifice  100 , wherein the inner orifice  200  guides liquid contents moving in a form of water stream from the container body (not illustrated) to be sprayed smoothly.

Although specific terms have been used herein, these are only intended to describe the present embodiments and are not intended to limit the meanings of the terms or to restrict the scope of the accompanying claims.
