Hereinafter, the spray mechanism that facilitates spraying of the remaining amount according to the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a configuration diagram of a spray device that facilitates spraying of a residual amount according to the present invention, Figure 2 is a state diagram of a spray device that facilitates spraying of a residual amount according to the present invention, and Figure 3 is a diagram of a spray device that facilitates spraying of a residual amount according to the present invention. This is also the state of use of the spray device.

As shown in FIGS. 1 to 3, the spray device for easy spraying of the remaining amount according to the present invention includes a container 100 with a flat bottom so that it can contain the contents and stand upright when placed on a flat surface. , a spraying part 200 that is assembled by screwing at the top of the container 100 and is easy to attach and detach, and pumps the contents inside the container to be sprayed to the outside, and the spraying part (200) inside the container 100 A drain tube 300 is coupled to the lower part of the container 100 and extends to the bottom of the container 100 and is formed of a flexible material, and is formed inside the drain tube 300 to prevent the drain tube 300 from being excessively bent. A shape-maintaining steel wire 400 is assembled to the lower part of the drain tube 300 and is in contact with the inner bottom surface of the container 100, which ensures a smooth flow of contents and allows the shape to be quickly restored in a bent state. It includes a central cone 500 that is formed.

Due to the above configuration, even if a small amount of contents remain inside the container 100, the central weight 500 coupled to the end of the drain tube 300 can always be maintained in contact with the contents by gravity, so that all remaining contents are sprayed. A spray device capable of doing so can be provided.

In the spray device according to the present invention, the end of the drain tube 300 is directed in the direction of gravity due to the weight of the central weight 500 assembled at the end of the drain tube 300, and the inside of the container 100 is gathered in the direction of gravity. By maintaining contact with the contents at all times, spraying is possible even if the remaining amount of contents is small.

In addition, due to the shape-maintaining steel wire 400 inside the drain tube 300, excessive bending of the drain tube 300 is prevented and restored through elastic action even when the spray device is used at an angle.

The container 100 can be made of various materials such as plastic or metal, and an appropriate material is selected and used depending on the purpose or usage environment. That is, if there is a risk that the contents may deteriorate due to external factors such as ultraviolet rays, it is preferable to use an opaque material, and if it is necessary to visually check the remaining amount of contents, it is preferable to use a transparent material.

In addition, a screw thread is formed at the entrance of the container 100 to facilitate assembly and disassembly with the injection unit 200.

A screw thread is formed on the inner peripheral surface of the coupling cap coupled with the container 100 at the lower part of the spray unit 200 to engage with the screw thread formed at the entrance of the container 100, so that the container 100 and the spray unit 200 A tube coupling guide 230, which can be screwed together and extends from the lower part of the spray unit 200 and partially protrudes into the container 100, is formed to couple the drain tube 300 in an inner or outer fitting manner.

Looking at the operation process, when the user applies pressure by pressing the injection lever 220, the piston connected to the injection lever 220 inside the injection unit 200 is compressed, the volume of air inside the cylinder is reduced, and the injection lever 220 When it returns to its original position, the contents inside the container 100 flow into the cylinder through the drain tube 300, and when the injection lever 220 is pressed again, the contents flowing into the cylinder are sprayed to the outside through the nozzle unit 210. .

The drain tube 300 is preferably made of a material such as silicon or plastic that is flexible and easy to process so that it can be easily deformed. Even if the spray device is tilted, the center weight 500 assembled at the lower end of the drain tube 300 ) moves in the direction of gravity due to the weight of the container (100) and always maintains contact with the contents inside the container (100) to facilitate inhalation or spraying of the contents.

In addition, due to the shape-maintaining steel wire 400 provided inside the drain tube 300, excessive bending of the drain tube 300 is prevented even when the spray device is tilted or turned over, and the shape-maintaining steel wire is maintained even when it is straightened again after use. It is possible for the drain tube 300 to be quickly restored due to the elasticity of 400.

The central weight 500 is composed of a combination of an internal weight 510 that can be inserted into the drain tube 300 and an external weight 520 that can be inserted outside the drain tube 300, and the outer diameter of the internal weight 510 The gap between the inner diameters of the external weight 520 is the same as or slightly smaller than the thickness of the drain tube 300, so that the internal weight 510 and the external weight 520 are press-fitted, or a threaded portion or external weight is formed on the outer surface of the internal weight 510. A threaded portion is formed on the inner surface of the weight 520 so that it can be assembled by screw coupling.

In addition, for a more robust assembly, the inner screws of the external weight 520 can be assembled with the internal weight 510 inserted, and the external screws of the internal weight 510 can also be assembled with the external weight 520 installed. .

Figure 4 is a detailed cross-sectional view of a drain tube into which a shape-maintaining steel wire is inserted according to another embodiment of the present invention, and Figure 5 is a bottom view of a drain tube or a tube coupling guide assembled with a central weight according to another embodiment of the present invention. Figure (a) and plan view (b), Figure 6 is a diagram showing an example of a shape-maintaining steel wire insertion method in the tube coupling guide portion of the injection unit according to another embodiment of the present invention, and Figure 7 is another embodiment of the present invention This is a drawing showing an example of the shape of the upper steel wire groove according to the embodiment.

4 to 7, the shape-maintaining steel wire 400 is located inside the drain tube 300, and the drain tube 300 easily moves in the direction of gravity due to the elasticity of the shape-maintaining steel wire 400. It is desirable to use an elastic material such as spring steel or plastic so that it can be restored.

In addition, the shape-maintaining steel wire 400 blocks the solution inlet of the injection unit 200 through the inside of the tube coupling guide 230, or prevents it from coming out of the tube of the internal weight 510. A locking portion 410 is formed at the end.

The size of the catching portion 410 is preferably smaller than the inlet of the tube coupling guide 230 and larger than the inner diameter of the internal weight 510.

In addition, when the locking portion 410 is bent in the same direction at both ends of the shape-maintaining steel wire 400, it has a structure bent in a 'ㄷ' shape, so that the middle pillar portion is close to one inner surface of the drain tube 300. They are adjacent to each other, and when the drain tube 300 and the shape-maintaining steel wire 400 are bent or restored, there is a possibility that they may be damaged because the load is not distributed evenly. Accordingly, the bending direction at both ends of the shape-maintaining steel wire 400 is left and right symmetrical so that the load applied to the shape-maintaining steel wire 400 in the process of bending or restoring the drain tube 300 and the shape-maintaining steel wire 400 It is desirable to configure the shape-retaining steel wire 400 to have a 'Z' shape so that durability is improved by dispersing.

In addition, the locking portion 410 formed at the top of the shape-maintaining steel wire 400 is inserted into the steel wire insertion portion 232 formed at the end of the tube coupling guide 230 to block the inlet at the bottom of the spraying unit 200 to prevent the contents from being released. Make sure not to disturb the flow, and hold the ends of the shape-maintaining steel wire 400 when the drain tube 300 and the shape-maintaining steel wire 400 are bent or restored to ensure smooth deformation.

The inner diameter of the steel wire insertion portion 232 is set to have a larger value than the size of the locking portion 410 so that the shape-maintaining steel wire 400 provided with the locking portion 410 is inserted into the steel wire insertion portion 232 or assembled. It can be assembled so that the catching portion 410 is caught on the steel wire insertion portion 232.

When the shape-maintaining steel wire 400 is inserted into the steel wire insertion part 232, the locking part 410 is inserted into the tube coupling guide 230 to receive stronger elastic support.

Also, if the length of the shape-maintaining steel wire 400 is too short, when the spray device is used, the upper end and the catching portion 410 of the shape-maintaining steel wire 400 move up and down in the steel wire insertion part 232. It may break away and damage the inner wall surface of the drain tube 300, or the bending or restoration performance of the drain tube 300 may be reduced, and the length of the shape-maintaining steel wire 400 may be reduced in the remaining space of the drain tube 300 (tube coupling guide). (230) If it is longer than the length (space from the end to the entrance of the central weight 500), smooth assembly of the internal weight 510 may be hindered or the shape maintaining steel wire 400 may remain bent, thereby reducing durability. , the length of the shape-maintaining steel wire 400 is preferably formed from the bottom surface of the tube coupling guide 230 to the top surface of the central weight 500.

In addition, in the case where the shape-maintaining steel wire 400 is straight without a catching portion 410, a straight upper steel wire groove 234 is formed on the outer surface of the tube coupling guide 230 to bend the shape-maintaining steel wire 400. Alternatively, the end of the shape-maintaining steel wire 400 may be held during the restoration process.

Therefore, in the case where the shape-maintaining steel wire 400 is straight without the catching portion 410, it is inserted into the interior of the drain tube 300, and one side of the shape-maintaining steel wire 400 is placed inside the tube coupling guide 230. , it can be press-fitted to the outside. Alternatively, it is fitted into the upper steel wire groove 234 formed on the outside of the tube coupling guide 230. At this time, the cross section of the upper steel wire groove 234 may be formed in a circular, semicircular, oval, triangular, square, or polygonal shape.

In addition, an upper steel wire locking hole 236 is formed in the tube coupling guide 230 and the internal weight 510, so that the locking portion 410 is fixed by hanging in the hole, thereby enabling a more secure connection.

Figure 8 is a diagram showing an example of a shape-maintaining steel wire insertion method in the center weight and mesh portion according to another embodiment of the present invention.

As shown in FIG. 8, in order to provide a stably fixed form without being separated during the bending or restoration process of the shape-maintaining steel wire 400, a locking portion 410 is provided at the center weight 500 and the mesh 530. A variety of insertion methods can be provided.

A more solid connection can be achieved by fixing it in a hanging manner. The insertion form can be formed in various forms such as the ‘ㄴ’ letter, the ‘ㄷ’ letter, and the ‘ㅁ’ letter.

In addition, a net 530 is formed at the lower part of the central weight 500, so that when the spray lever 220 is operated to spray the contents stored inside the container 100, foreign substances that may be contained in the contents are removed from the drain tube ( 300) By blocking the inflow of foreign substances into the interior, it is possible to prevent malfunctions caused by the inflow of foreign substances into the drain tube 300 or the spray unit 200.

When the mesh 530 is formed, the bottom surface of the central weight 500 and the mesh 530 where the inner weight 510 and the outer weight 520 are combined, as shown in (g) to (l) of Figure 8 By forming a lower steel wire catching hole 512 therebetween or forming a lower steel wire groove 514 passing through the mesh 530 as shown in (m) to (o), the catching portion 410 is formed in the shape of 'ㄴ' or 'ㄷ'. A more solid connection can be achieved by fixing it in a shape such as 'ㅁ' or 'ㅁ'.

By blocking the inflow of foreign substances into the drain tube 300 or spray unit 200, failure due to the inflow of foreign substances into the drain tube 300 or spray unit 200 can be prevented in advance. And, as shown in Figures 14 (c) and (d), only one of the outer peripheral surface of the internal weight 510 or the inner peripheral surface of the external weight 520 may be assembled by forming threads.

As shown in (a) of Figure 15, the net 530 is pressure-fitted to the outside of the external weight 520, or assembled by screwing with threads formed on the outer peripheral surface of the external weight 520, as shown in Figure 15 (b). It can be assembled by pressure fitting into the interior of the internal weight 510 as shown in (c) of Figure 15, or may be assembled by screwing with a thread formed on the inner peripheral surface of the internal weight 510 as shown in (d) of Figure 15. there is.

As shown in Figure 16, the bottom of the mesh 530, the inner weight 510, and the outer weight 520 are in close contact with the bottom surface of the container 100 and are shaped like a flat shape, a semicircular shape, an oblique cut shape, etc. so as not to interfere with the suction of the solution. It can be formed in various shapes such as protruding or recessed.

Figure 17 is a cross-sectional view showing an example of the assembled state of the central weight according to another embodiment of the present invention.

As another embodiment of the present invention, the central weight 500 can be combined by interference fit of the internal weight 510 and the external weight 520, but as shown in FIG. 16, the outer peripheral surface of the internal weight 510 The coupling can be further strengthened through the assembly protrusion 516 formed in and the assembly groove 522 formed on the inner peripheral surface of the external weight 520.

At this time, since the drain tube 300 between the inner weight 510 and the outer weight 520 uses a flexible material that can be easily deformed, the curved shape formed between the assembly protrusion 516 and the assembly groove 522 It can be transformed and maintained into a shape that corresponds to space.

Accordingly, when the central weight 500 is coupled to the distal end of the drain tube 300, the friction force increases due to the curved surface formed between the assembly protrusion 516 and the assembly groove 522, making the coupling more robust and easy to separate or Make sure it doesn't come off.

Figure 18 is a diagram showing an example of the shape of a locking portion according to another embodiment of the present invention.

As shown in Figure 18, the locking portions 410 formed at both ends of the shape maintaining steel wire 400 are 'ㄴ'-shaped, 'ㄷ'-shaped, 'ㅁ'-shaped, circular, triangular, square, finished, or It can be formed in a shape such as a polygon, and of course, it can be applied in various shapes considering aesthetics at a level that does not affect the function of the above-mentioned locking portion 410.

Figure 19 is a diagram showing an example of a drain tube formed with a ring-shaped protrusion according to another embodiment of the present invention.

As shown in FIG. 19, when formed by screw coupling among the above-mentioned contents, the coupling force can be increased by forming a ring-shaped protrusion instead of the screw. The outer ring-shaped protrusion 450 formed on the outside of the coupling portion of the central cone 500 or the mesh 530 as shown in Figures 19 (a) and (b) and the central cone 500 as shown in Figures 19 (c) and (ㅇ). It can be formed with an inner ring-shaped protrusion 460 formed inside the coupling portion of the mesh 530. In this case, the shapes 452 and 462 of the ring-shaped protrusion formed are formed in various shapes such as circular, triangular, square, and trapezoid. can do.
