2. Description of the Related Art Generally, a spray container ejects liquid contents in a container in a spray state when a user presses the spray button, and is generally widely used in liquid cosmetics or medicines.

Among these spray containers, the "sprayer" (Korean Patent Laid-Open No. 2000-0049441) of Patent Document 1 of the following is an ordinary spray device in which a tube case having a suction port other than the tube and a ball for interrupting the suction port, And a double suction apparatus in which the spray can be sprayed even when the spray container is upside down and the shape of the secondary valve and the housing is improved so that the both parts are always in contact with each other, There is an advantage that the deterioration of the spray performance is prevented due to the deformation of the secondary valve that occurs during the spray operation.

However, in the " atomizer " of Patent Document 1, there is no separate numerical value and shape in the discharge hole portion in the process of pressurizing the button and spraying the liquid contents stored in the container through the nozzle, The injection angle, which is the most important element among the elements, is not formed in the optimal state according to the purpose of use, and thus the user can not provide the best injection performance per body part.

To solve this problem, as shown in Figs. 1 and 2, in a spray orifice structure (1) which is coupled to a discharge portion (11) of a spray injection button (10) The outer orifice 100 is formed by a spray orifice body insertion hole 110 formed to be inserted into the discharge portion 11 and having a spray orifice body 200 inserted therein, And a conical first jetting port 120 formed to be gradually smaller in diameter from a distal end side of the spray orifice body insertion hole 110 to a distal end side of the spray orifice body insertion hole 110. The first jetting port 120 is formed to extend from a distal end side of the first jetting port 120 A second jetting port 130 having a predetermined diameter and a predetermined length is formed in the second jetting port 130. The jetting angle of the jetting port 130 is set to a jetting angle A spray orifice structure (1) can be proposed which is characterized in that the degree is determined.

In the case of the spray orifice structure 1 having such a structure, the spray orifice body 200 is combined with the spray orifice body 200, and the spray orifice body 200 may be formed as shown in FIG. 1 or 2, The spray orifice body 200 is a component to be inserted into the outer orifice 100 and inserted into the outer orifice body 110 to disperse the liquid contents moving in the form of water from the container body (not shown) It serves as a guide.

The spray orifice body 200 is usually manufactured using a mold. In this case, the flatness of the inlet surface 210 of the spray orifice body 200 greatly affects the spray quality.

However, in the case of a conventional injection mold, there is a difference between the cavity for forming the product and the shape of the finished product at the room temperature in accordance with the volume change according to the temperature of the injection material. In order to compensate, a method of changing the shape of the cavity through experience, know-how or complicated simulation has been mainly used.

However, this conventional method may be able to cancel the contraction according to the injection temperature, but since it can not cope with the change of the shrinkage rate due to the difference of the injection pressure, if the injection pressure changes a little, There is a problem that distortion is inevitably generated.

In this case, the depressed portion 410 can cancel the shrinkage due to the temperature difference between the injection temperature and the normal temperature during injection of the injection material P for forming the spray orifice body 200, ) Is flattened. That is, it is preferable to process it so as to cope with the shape change due to the temperature difference between the injection temperature and the normal temperature.

3, the supporting core 420 is coupled to the first core 300, and the elastic moving core 400 is elastically supported by the elastic means 440, 430 are formed. The support core 420 may be integrally coupled to the first core 300 using fastening means and may be in contact with the first core 300 by the mold driving means in the injection process Or the like.

Further, it is preferable that the elastic movable core 400 is configured to have a predetermined elastic retraction distance d according to the injection pressure when the injection material P is injected. That is, it is preferable that the elastic modulus of the elastic means 440 is determined according to the injection material injection pressure belonging to the injection condition. In this case, it is found that the predetermined elastic retraction distance d is preferably in the range of 0.4 mm ± 0.1 mm as a result of repetitive test injection.
