Referring to FIGS. 5 and 6 , the injection body 410 and the contact portion 430 may be integrally formed, and the cross-sectional area of the contact portion 430 may be relatively larger than that of the injection body 410 based on the central axis in the longitudinal direction.

Referring to FIGS. 5 and 6 , the outer diameter of the contact portion 430 may be formed to be relatively larger than the outer diameter of the injection body 410 .

Therefore, the contact portion 430 can be placed horizontally on the base body 117 and in close contact, so that the outflow of the gas G from the accommodating portion 100 to the outside can be blocked.

Referring to FIG. 5 and FIG. 6 , the injection body 410 of another embodiment of the present invention may be exposed outside the accommodating portion 100 so as to be able to be connected to an external device. The contact portion 430 is connected to the injection body 410, and may be connected to the other side of the injection body 410 (the upper side with reference to FIG. 5 ), and the other side is connected to the side of the injection body 410 that can be contacted with an external device (with Figure 5 is the lower side of the reference) facing each other.

Referring to FIGS. 5 and 6 , the injection part 400 , specifically, the injection body 410 is formed with an injection flow path 411 , and the gas G can be supplied from the outside to the inside of the housing part 100 through the injection flow path 411 . Referring to FIGS. 5 and 6 , the injection flow path 411 may be formed by cutting one side of the injection body 410 .

Referring to FIG. 5 , the injection part 400 is connected to an external device, and the gas G is supplied through the injection flow path 411. The injection part 400 moves upward (with reference to FIG. 5 ) due to the pressure of the supplied gas, and one side of the injection part 400 is Specifically, one surface of the contact portion 430 (the lower surface based on FIG. 5 ) is separated from the base body 117 , and the gas G can be supplied to the accommodating portion 100 through the space formed between the base body 117 and the contact portion 430 .

Referring to FIG. 6 , the injection part 400 may be formed of an elastically deformable material. Therefore, after the supply of the gas G is completed, if the external device for supplying the gas G is removed, the pressure of the gas G applied on the upper side of the injection part 400 will The injection part 400 is elastically deformed, specifically, the contact part 400 is elastically deformed, and is in close contact with the base body 117 , which can prevent the gas G from flowing out of the accommodating part 100 .

The contact portion 430 is arranged in a contactable manner at the center portion of the base body 117. Since the outer diameter of the contact portion 430 is formed larger than the outer diameter of the injection body 410 and the inner diameter of the center portion of the base body 117, the contact portion 430 can be placed horizontally on the base body. 117.

The contact portion 430 is horizontally supported on the base body 117. Therefore, if the gas G is supplied to the interior of the accommodating portion 100 through the injection body 410, the injection portion 400, specifically, the contact portion 430, is pushed downward by the pressure of the gas G. The pressure is applied in the direction (with reference to FIG. 5 ) so that the state where the injection part 400 is in close contact with the base part 116 is maintained.

Referring to FIG. 5 and FIG. 6 , according to another embodiment of the present invention, the injection flow path 411 formed in the injection part 400 , specifically, the injection body 410 may be formed in a cut shape.

Specifically, the injection flow path 411 is formed in a cylindrical shape, but it is not limited to this, and various modifications are possible within the technical idea that the flow path can be formed and the gas G can be supplied from the outside.

Referring to FIGS. 5 and 6 , the injection flow path 411 may be formed in the shape of a groove on the injection body 410 side, and one side (the left side with reference to FIG. 5 ) may be opened along the longitudinal axis.

Therefore, the injection flow path 411 formed in the injection main body 410 can be connected to the inner peripheral surface of the center portion of the base main body 117 facing each other, and a path for supplying the gas G can be formed.

The injection flow path 411 formed in the injection body 410 is connected to the inner peripheral surface of the base body 117 to form a supply path for the gas G. Therefore, the injection part 400, specifically, the contact part can be connected to the injection part 400 by the pressure of the supplied gas G. 430 is pushed up, so that the gas G can flow into the accommodating part 100 through the space formed between the injection part 400 and the inner peripheral surface of the base body 117 .

The user can put a tool such as a rod into the injection flow path 411 formed in the injection body 410, and push the injection part 400, specifically, the contact part 430 in one direction (upward direction with reference to FIG. 6). ).

A tool such as a rod is put in and the contact part 430 is pushed, so that the base part 116 can be separated from the contact part 430 , and the gas G contained in the accommodating part 100 can be discharged.

Therefore, when discarding the ejection device 2 that has completely used up the contents F accommodated in the accommodating portion 100 , specifically, the contents F accommodated in the second main body portion 130 , the user can use a tool such as a rod to inject The injection flow path 411 formed by the main body 410 pushes the contact portion 430 toward the nozzle portion 200 side (upward direction with reference to FIG. 6 ), and easily discharges the gas G to the outside. In addition to the configuration of the base portion 116 and the injection portion 400 of the spray device 2 according to another embodiment of the present invention, the configurations, working principles and effects of the accommodating portion 100 , the nozzle portion 200 , and the valve portion 300 are the same as those of the spray device according to one embodiment of the present invention. The accommodating part 100, the nozzle part 200, and the valve part 300 of 1 are the same, and therefore the detailed description is omitted to the extent that they overlap.

The first main body and the second main body part of the spray device according to one embodiment of the present invention are overlapped, and the effect is that the pressure applied to the movable part arranged inside the second main body part is maintained so that it can be held at an angle with the user's grasping angle. , Regardless of gravity, when the flow path formed by the nozzle part is opened, the content is quickly ejected.

The specific implementation described in this invention is an example only, and is not intended to limit the scope of this invention in any way. For the sake of brevity of the description, the description of the conventional electronic configuration, control system, software, and other functions of the system may be omitted. In addition, the line connection or the connection member between the components shown in the drawings exemplarily shows the functional connection and/or the physical or circuit connection, and in the actual device, it can be replaced or shown as additional various functions. connection, physical connection or electrical connection. In addition, if there is no specific mention such as "essentially", "importantly", etc., it may not be a constituent element that is necessary for the application of the present invention.
