Description

Cosmetic container {COSMETIC TUBE}

The present invention relates to a cosmetic container, and more particularly, by having an air inlet at the bottom of a cylinder in which a cosmetic solution is accommodated, so that external air can be introduced into the piston, which pushes the cosmetic liquid forward and then moves again. It's about cosmetic containers that don't come back.

In general, when using liquid cosmetics, a cosmetic solution in a glass bottle or a plastic bottle is applied to the face by applying a brush to a face. This method requires the use of a brush separately from the cosmetic container, which is inconvenient in storage or use.

In order to solve this problem, many cosmetic containers are provided with a brush integrally disclosed.

One of them is Korean Patent Publication No. 2006-113336 "Cosmetic Brush" published on November 2, 2006 (hereinafter referred to as "prior art").

1a and 1b is a perspective view and a cross-sectional view showing the structure of a cosmetic container according to the prior art, with reference to this will be described in the prior art.

Cosmetic brush 1 according to the prior art is the outer body 10 and the upper screwed by the coupler 30, press the lower portion of the inner body 20 is provided with a sealing ring 21 inward. Vertical and horizontal solution guide passages (42) and (43) formed in the discharge port 40, the cosmetic solution stored in the inner body 20 by the air pressure generated while the inner body 20 is raised and lowered according to the The elastic force of the spring 49 installed in the coupling hole 30 formed in the upper portion of the inner body 20 while allowing the discharge hole 44 and the solution transfer pipe 51 to be properly discharged to the brush 50 side. The inner body 20 is lowered and returned by the same, and at the same time, the vertical solution guide passage 42 is closed by the spring 46 and the reverse direction 45 in the discharge hole 44 so that the cosmetic solution is not discharged. The inner body 20 is moved up and down by pressing and releasing the lower end of the inner body 20. The cosmetic solution stored in the interior of the 20 is discharged to the brush 50 through the vertical and horizontal solution guide passages 42 and 43 and the discharge hole 44 and the solution transfer pipe 51 formed in the discharge port 40. It is to freely control the blocking.

On the other hand, the inside of the coupler 30, the brush 50 is provided in the upper portion, the discharge port 40 is inserted into the spring 49 is inserted into the lower portion is inserted and coupled, the discharge hole 40 is An inclined circumferential portion 41 is formed at a lower portion thereof, and a vertical solution guide passage 42 and a horizontal solution guide passage 43 are formed at a central portion thereof so as to communicate with a discharge hole 44 penetrating to an upper portion of the center portion. The reverse side 45 and the spring 46 are inserted into the inside of the 44.

In addition, the upper portion of the discharge hole 44 to form the discharge port 40 formed as described above is installed is fitted with a solution transfer pipe 51 having a brush 50 is fitted.

Usually, the discharge port 40 in which the spring 49 is fitted into the inner side of the coupler 30 coupled to the upper portion of the inner body 20 is fitted to the inner body 20 by the elastic force of the spring 49. Is in a downward state.

At this time, the discharge port 40 is fitted into the inside of the coupler 30 is inclined circumferential portion 41 formed at the lower end of the through hole 34 formed as the lower end of the coupler 30 is the through hole The opening 34 is in a state where the vertical and horizontal solution guide passages 42 and 43 formed in the discharge port 40 communicate with the discharge hole 44 and the solution transfer pipe 51.

As described above, the cosmetic solution flows into the vertical and horizontal solution guide passages 42 and 43 and the inside of the coupling hole 30 communicated by the through hole 34.

On the other hand, in the above state, the inner body 20 is downward and no pressure is applied, and the reverse finger 45 inserted into the discharge hole 44 has an upper portion of the vertical solution guide passage 42. It becomes the state which is closing.

Therefore, when the cosmetic brush 1 in the state in which the through hole 34 is opened as described above, the brush 50 is directed downward, and then the lower end of the inner body 20 is pressed, as shown in FIG. 4. (It is shown to face upward in the drawing) The inner body 20 and the coupling hole 30 coupled to the upper portion is moved to the lower end of the discharge port 40 fitted in the coupling hole 30 through hole 34 After passing through the inner body 20 is protruded into the state, the inward annular end step 35 formed in the lower end of the coupling hole 30 is located in the lower peripheral portion of the discharge port 40 through hole 44 At the same time as the closing ring 22 is inserted into the discharge hole 44 by the pressure generated by the pressure of the inner body 20 is inserted into the discharge hole 44 is raised to open the coupling sphere 30 of the The cosmetic solution introduced into the vertical and horizontal solution guide passages 42 and 43 is formed around the discharge hole 44 and the reverse finger 45. Of the solution through a vertical groove (45a) it is transferred to songgwan 51 is discharged to the brush 50.

As described above, the cosmetic brush 1 of the present invention, in which the through hole 34 is opened and closed by repeatedly pressing the inner body 20, moves the cosmetic solution stored in the inner body 20 to the brush 50 side. In order to discharge and use, as the user presses the lower portion of the inner body 20 coupled to the inside of the outer body 10, the inner body 20 is lifted, and at this time, the inner body 20 is inserted into the inner body 20. While the inside of the inner body 20 is compressed by the combined sealing ring 22 and the inclined peripheral portion 41 formed instantaneously the cosmetic solution stored in the inner body 20 and the discharge port 40 The proper amount is pushed into the inside of the coupler 30 through the through hole 34 formed at the inner lower end of the coupler 30, and when the inner body 20 is completely pressed, the inner body 20 is raised as much as possible to engage the coupler. An inwardly rounded step 35 formed at the lower end of the sphere 30 is provided at the lower end of the discharge port 40. The through hole 34 is closed by being located.

At this time, the cosmetic solution is forcibly transported by pushing the reverse finger 45 inserted into the discharge hole 34 to the top to open the upper portion of the vertical solution guide passage 42.

On the other hand, the sealing O-ring 48 interposed in the recessed groove 47 formed at the circumference of the discharge port 40 prevents the cosmetic solution introduced into the coupling port 30 from leaking to the outside of the coupling port 30. .

Therefore, when the force is released to the pressed inner body 20, the inner body 20 is returned to its original state by the elasticity of the spring 49 supported by the discharge hole 40 inside the coupling hole 30. It is in a state.

In addition, while the inner body 20 is returned to its original state, the internal pressure is increased, and the reverse displacement 45 inserted into the discharge hole 44 is sucked to close the upper portion of the vertical solution guide passage 42.

In the case of applying the prior art as described above, a separate reverse lever 45 for blocking the discharge hole 44 of the discharge port 40 should be used, and for restoring the reverse finger 45 to its original position. The spring 46 must be installed to prevent the outflow of the cosmetic solution.

However, in order to manufacture the brush of such a structure, not only the precision processing is required, but also has the disadvantage that the structure is complicated and the cost increases.

In addition, while repeatedly pressing the lower end of the inner body 20, the reverse valve 45 must be opened and closed by the pressure of the cosmetic solution itself, and if the amount of the cosmetic solution is small by repeatedly pressing a button or using it for a long time, it does not work properly. There is a problem.

Or malfunction does not occur.

Hereinafter, a cosmetic container 100 according to an embodiment of the present invention with reference to the drawings.

Figure 2 is a perspective view showing the structure of a cosmetic container according to a first embodiment of the present invention, Figure 3 is a cross-sectional view showing a coupling state of the cosmetic container.

Referring to Figures 2 and 3, the cosmetic container 100 is composed of a cylindrical cylinder 102 of the body. Cylinder 102 has a storage space (A) for storing the cosmetic solution therein, the liquid cosmetic solution is stored in the storage space (A).

The discharge port 102a through which the cosmetic solution is discharged is formed in the upper portion of the cylinder 102.

And the lower portion is formed with a compression space (B) for storing the air introduced from the outside. The cosmetic solution is discharged out by the force of the air introduced into the compression space (B).

An outward screw 102b is formed on the outer circumferential surface of the lower portion of the cylinder 102.

Coupling member 104 is screwed to the upper portion of the cylinder 102, the coupling member 104 has a substantially cylindrical shape, the upper portion is formed in a shape that the approximately cylindrical brush binding groove 104a entered into the inside. In the brush binding groove 104a, a brush 106 made of animal hair, cotton, sponge, or the like is seated and fixed.

A partition 104d is formed horizontally in the center of the coupling member 104.

Inflow hole 104c through which the cosmetic solution enters is formed in the center of the bottom surface of the partition 104d, and a solution movement path 104b through which the cosmetic solution is discharged is formed in the center of the top surface.

The inlet hole 104c is fixed in a state where the distal end thereof is inserted into the discharge port 102a formed in the upper portion of the cylinder 102. Since the inner wall surface of the discharge port 102a is fixed in close contact with the outer wall surface of the inlet hole 104c, the cosmetic solution flowing out of the discharge hole 102a does not leak out to the outside and enters the inlet hole 104c.

The solution movement path 104b is formed to protrude from the surface of the central partition 104d, and is installed with the end inserted into the middle portion of the length of the brush 106. Therefore, the cosmetic solution discharged through the solution movement path 104b is evenly buried in the brush 106.

The lid 108 is coupled to the upper end of the cylinder 102, in which the brush 106 is stored.

On the other hand, the piston 110 is inserted into the storage space (A) of the cylinder (102). The piston 110 is installed to slide in close contact with the inner wall surface of the storage space (A), while the cosmetic solution is stored in the storage space (A) while the piston 110 advances toward the discharge port (102a) The solution is discharged in the direction of the brush 106.

The push button 114 is inserted into the distal end of the compression space (B) of the cylinder (102). Push button 114 is slidably installed in close contact with the inner wall surface of the compression space (B). One or two rubber rings 118 are provided on the outer circumferential surface of the push button 114, and the rubber ring 118 has air between the inner wall surface of the compression space B and the outer wall surface of the push button 114. Prevent entry and exit

A spring 112 is installed inside the compression space B, and the spring 112 contacts one side of the push button 114. The spring 112 provides a restoring force for the push button 114 to return to its original position when the user presses and releases the push button 114 to use the cosmetic.

And around the push button 114, about two air inlet device 116 is installed. Since the air inlet device 116 is inserted into the groove formed in the push button 114, the push button 114 moves together when it is moved up and down.

4 is a cross-sectional view showing the structure of the air inlet device, Figure 5 is a cross-sectional view showing the principle of opening and closing the air inlet device.

As shown in FIG. 4, the air inlet device 116 is generally cylindrical in shape, and the lower end of the air inlet device 116 has a larger diameter than that of the center to form a step. And the air movement path 116a is formed in the center of the lower surface. The side of the upper surface is slightly obliquely cut, and a straight cut surface 116b is formed at the center of the upper surface.

When the air inlet device 116 is installed in the push button 114, the air movement passage 116a of the lower surface is fixed to the outside, the cutting surface 116b of the upper surface in contact with the compression space (B). . Accordingly, when the incision surface 116b is opened, the outside of the cosmetic container 100 and the compression space B communicate with each other. Because the air inlet device 116 is made of a soft and resilient material such as silicon, the shape change may occur even with a small force.

External air that enters through the air movement passage 116a in the state in which the incision surface 116b is opened is stored in the compressed air B to exert a force to push up the piston 110.

FIG. 5A illustrates a state in which the cutting surface 116b is closed because the pressure in the compression space B, which the cutting surface 116b of the upper surface is in contact with, is higher than the outside. When the pressure in the compression space (B) is high, the incision surface 116b is closed while pressure is transmitted to the slanted side.

Then, when the pressure in the compression space (B) is lower than the outside, as shown in (b), the pressure of the air movement passage 116a in contact with the outside becomes relatively high and the outside air is directed toward the incision surface 116b. When the force is applied, the incision surface 116b is slightly opened so that the outside air can enter the compression space B.

On the other hand, the button cap 120 is provided below the push button 114. An inward screw 120a is formed on the upper inner wall of the button cap 120 to be screwed to the outward screw 102b formed at the bottom of the cylinder 102.

On the other hand, Figure 6a to 6d is a cross-sectional view showing the operation sequence of the cosmetic container.

In a state in which no force is applied to the push button 114 as shown in FIG. 6A, the piston 110 does not move, and the cut surface 116b of the air inlet device 116 also remains closed. Therefore, the cosmetic solution does not flow out of the container.

When the pressure is applied to the push button 114 as shown in Figure 6b, the push button 114 is pushed forward to press the spring 112, the volume of the compression space (B) becomes smaller, the pressure inside the compression space (B) Will be higher.

Therefore, the piston 110 is advanced upward by the air pressure in the compression space (B). (FIG. 6C) The piston 110 moves forward while applying pressure to the cosmetic solution stored in the storage space A, and the cosmetic solution is It is transmitted to the brush 106 via the discharge port 102a, the inlet hole 104c, and the solution movement path 104b.

After a certain amount of cosmetic solution is discharged, when the pressure applied to the push button 114 is released, the push button 114 retreats downward by the elastic force of the spring 112 and returns to its original position. At this time, as the volume of the compression space (B) increases, the internal pressure drops, and the incision surface (116b) of the air inlet device 116 is opened at the moment, and the outside air enters the compression space (B). When the outside air enters to some extent and the pressure inside the compression space (B) becomes equal to the outside pressure, the incision surface 116b is closed again, and the access of the air is stopped.

Therefore, the piston 110 is slightly advanced as compared to the beginning, the compression space (B) is to maintain a slightly larger state.

By repeating this operation, the piston 110 goes up more and more, and when the exhaustion of the cosmetic solution, the piston 110 is raised to the top of the storage space (A), when the cosmetic solution is exhausted The contents can be refilled or a cylinder 102 filled with cosmetic solution can be purchased and replaced.

On the other hand, Figure 7 is a perspective view showing the structure of a cosmetic container according to a second embodiment of the present invention.

The cosmetic container 100 according to the second embodiment is slightly different from the above-described embodiment in the position and direction of the air inlet device 116.

As shown in FIG. 7, the air inlet hole 102c is formed at the lower side of the cylinder 102, and the air inlet device 116 is inserted into and fixed to the air inlet hole 102c in the lateral direction. The position where the air inlet hole 102c is formed is preferably a side wall of the compression space B.

Also in the second embodiment, when the push button 114 is pressed, the pressure in the compression space B is increased to close the incision surface 116b, and when the pressure is released, the incision surface 116b is opened momentarily and the outside air enters the inside. The procedure is identical.
