Description

Apparatus for opening shutting nozzle of cosmetic case}

The present invention relates to a nozzle opening and closing device of the cosmetic container, and more particularly, in the pumping device of the cosmetic container to be installed in the opening of the cosmetic container to discharge the contents by a predetermined amount by the pumping operation by the pressing operation, after the pumping operation The remaining contents on the nozzle side are sucked in the reverse direction to maintain the cleanness around the nozzles while preventing the outside air from flowing into the pump during standby, resulting in drying, contamination and deterioration of the contents in the fluid passage. It relates to a nozzle opening and closing device of the cosmetic container to prevent.

Generally, a cosmetic container for storing a liquid or gel cosmetics is equipped with a pressure pumping device for discharging the contents to the outside by a predetermined amount in the inlet.

These pressurized pumping devices have been proposed and widely used so far, and the alternative principle of these is installed on the nozzle cap for opening and closing the inlet of the cosmetic container, when the operation button is pressed with a finger, the operation according to the pressure As a result, a vacuum pressure is generated inside, and the contents stored in the container are discharged to the outside through the nozzle by a predetermined amount by the vacuum pressure.

Looking at the pumping apparatus of the conventionally proposed cosmetic container as an example, it can be mentioned Utility Model Registration No. 187929.

As shown in Figures 1 and 2 of the accompanying drawings, it is equipped with a nozzle cap (2) for opening and closing the screw in the injection port of the cosmetic container (1) and the nozzle cap (2) has an operation having a nozzle (3) The button 4 is installed to move up and down by the user's pressing operation.

In addition, the fluid passage tube 5 and the plunger 8 are connected to the lower side of the operation button 4 side by side, the plunger 8 is elastically supported by the return spring 6 of the lower side orifice through which the contents pass ( At the same time as 7) is drilled, the outer diameter is fitted with a valve 10 which is closely coupled to the inner diameter of the cylinder 9 and is operated by lifting.

In addition, the inlet 9a of the cylinder 9 is provided with a ball valve 11 for opening and closing it, the ball valve 11 is a flange 12 and another spring 13 supported by the return spring (6) It is supported by and is configured to open and close.

Accordingly, the plunger 8 connected by the fluid passage tube 5 is lowered while compressing the return spring 6 in response to the pressing of the operation button 4, and the valve 10 and the plunger 8 are pressed by the pressing force thereof. The contents inside the cylinder 9 pass through the orifice 7 of the plunger 8 and are discharged to the nozzle 3 side while the gap is opened.

At this time, the ball valve 11 is in a state in which the suction port 9a is closed by the pressure of the cylinder 9 and the spring 13.

On the contrary, when the operation button 4 is released, the plunger 8, the fluid passage tube 5, the operation button 4, etc. are raised by the return force of the return spring 6, and the cylinder ( As the vacuum pressure is generated in 9), the ball valve 11 opens the suction port 9a, whereby the contents in the container 1 flow into the compression chamber in the cylinder 9 to await discharge.

However, such a conventional structure is that the fluid passage between the nozzle 3 and the plunger 8 is in an open state, and after the contents are discharged to the outside through the nozzle 3, some of the residues of the nozzle 3 There is a problem that remains at the tip.

That is, when the sprayer is not used, the plunger 8 and the valve 10 are coupled to each other so that the orifice 7 is closed. Although not introduced, there is a problem in that the contents remain on the plunger 8, the fluid passage tube 5, and the fluid passage R connected to the nozzle 3 to flow to the tip of the nozzle 3.

This is not only a bad appearance, but also a disadvantage that is not clean, there is a disadvantage that wastes the contents.

In addition to these problems, the external components are introduced into the fluid passage (R) through the nozzle (3), there is a disadvantage that the original components fade, such as the contents remaining in the fluid passage (R) is easily dried or vaporized, If this phenomenon continues for a long time, there is a problem such as the contents are contaminated or deteriorated.

In particular, when the contents are solidified in the fluid passage (R) due to the above problems, the fluid passage is blocked, and the pumping operation is not performed smoothly. In addition, a failure occurs due to such a load.

On the other hand, Utility Model Registration No. 246274 has been proposed to improve the above structure.

This is configured so that the suction button is applied in the reverse direction when the operation button is in the original position by the return spring after the contents are discharged to the outside, so that the contents do not remain around the nozzle.

However, in the above configuration, although the suction force generated in the process of returning the operation button to the original position can suck the contents remaining on the nozzle to some extent, the fluid passage through which the contents are discharged is opened to the atmosphere through the nozzle. The state did not fundamentally solve the above problems.

Therefore, the present invention has been made in consideration of the conventional problems as described above, and its purpose is to improve the pumping function of the cosmetic container and to keep the nozzle surrounding the contents discharged at all times clean, and in the operating atmosphere, the outside air is internally It is to provide a nozzle opening and closing device of the cosmetic container to prevent the contamination of the contents and the phenomenon of deterioration in advance.

The present invention for achieving this object is achieved by having a nozzle opening and closing means for opening and closing operation by the suction force by the elasticity of the spring and the pressing operation of the operation button on the nozzle of the contents pumping means.

The nozzle opening and closing means according to the present invention is a nozzle tube having a nozzle hole, a tip valve which is installed in the nozzle tube to open and close the nozzle hole by the forward and backward operation, and made of a synthetic resin material fastened to the tip valve to support it The spring is equipped with a tip valve to open the nozzle hole for smooth discharge, and the tip valve opens the nozzle hole by the spring force when not in use. By closing the contents to prevent the contents from flowing out to the outside as well as blocking the inflow of external air to prevent contamination and deterioration of the contents.

At this time, the distribution hole 121 on the flange 122 is not only one embodiment, as shown in Figure 8 of the accompanying drawings as another embodiment a plurality of semi-circular groove ( 124, or as shown in Figure 9 of the accompanying drawings it will be obvious that the hole 125 through the body of the tip valve 120 and the like.

In addition, the nozzle opening and closing means 100 of the present invention is not limited to the pumping means of the cosmetic container illustrated in the present invention, the same effect can be expected to be applied to any other container having a pumping means by the pressing force.

Therefore, the nozzle cap 20 to which the nozzle opening and closing means 100 of the present invention is applied is used by screwing into the inlet of the cosmetic container as usual, and in FIG. 3 and FIG. It is shown.

In this state, the operation button 30 is maintained upward by the elastic force of the return spring 40, and the axial valve 70 is lowered in the compression chamber S so that the inlet 51 of the cylinder 50 is lowered. Will remain closed.

Therefore, the phenomenon that the contents flow down to the outside through the nozzle hole 111 is not only fundamentally prevented, but the contents filled therein are safely protected by the external air not being introduced into the inside through the nozzle hole 111.

When the user presses the operation button 30 to use the contents in this state, the operation button 30 is lowered while compressing the return spring 40, whereby the piston 60 and the piston valve 80 The piston valve 80 compresses the compression chamber S in the cylinder 50 by sequentially descending while opening them sequentially while continuing to descend.

Therefore, the contents in the compression chamber (S) are routed along the open passage between the piston valve (80) and the piston (60), the inner diameter of the fluid passage tube (31), and the fluid passage (33) of the operation button (30). It is discharged to the outside through the nozzle hole 111 of the nozzle opening and closing means according to the present invention.

In more detail, Figure 4 of the accompanying drawings shows a state before operation, when the contents are discharged by the pressing operation of the operation button 30 in this state, as shown in Figure 6 of the accompanying drawings After entering the rear space (B) through the fluid passage 33, it is introduced into the front space (A) through the small flow holes 121 formed on the flange 122 of the tip valve 120 by the discharge pressure. .

Subsequently, the contents introduced into the front space A are vortexed therein to generate a strong expansion pressure, and the expansion pressure acts on a relatively wide surface of the flange 122 to operate the tip valve 120 backward. .

The tip valve 120 is reversely operated by a predetermined interval while compressing the spring 130 as shown in Figure 7 of the drawing, the front end is open the nozzle hole 111, so that the contents are smoothly discharged to the outside Will be.

On the contrary, when the pressed operation button 30 is released, the pumping pressure applied to the nozzle opening and closing means 100 is also released by returning to the original position by the elastic force of the return spring 40, thereby compressing the nozzle opening and closing means 100. The tip valve 120 is moved forward by the return force of the spring 130 so that the front end closes the nozzle hole 111.

In addition, as the operation button 30 is raised by the return force, the fluid passage pipe 31, the piston 60, and the piston valve 80 connected thereto are sequentially raised, so that a strong vacuum pressure in the operation chamber S is achieved. This occurs, and the axial valve 70 is raised by the vacuum pressure thereof to fill the contents in the container into the operation chamber (S) to wait for the next operation.

At the same time, as the operation button 30 is raised, the volume is increased in the fluid passage 33, which is a space between the fluid passage tube 31 and the piston 60, and a strong suction force is generated to the nozzle side. It is retracted to some extent inside the pump.

Therefore, the above-mentioned feedback phenomenon and the operation of the nozzle opening and closing means can always maintain the cleanness on the nozzle side, and the contents can be protected because no outside air flows into the pump even during standby.

As described in detail above, the present invention includes a separate nozzle opening and closing means on the nozzle side through which the contents of various cosmetic containers are discharged to the outside so that the nozzle is opened by the pumping pressure during the pumping operation of the contents so that the contents can be smoothly discharged. At the same time, when the pumping operation is eliminated, the nozzle hole is closed by the return force of the spring, and at the same time, the contents are prevented from flowing down to the outside due to the feedback phenomenon inside the pump.

Therefore, the contents are not left at the tip of the nozzle, which not only improves the appearance, but also maintains cleanliness, and also prevents contamination and deterioration of contents by preventing external air from entering the pump during standby. In addition, there is an advantage such as to prevent the coagulation of the contents due to evaporation and component degradation.
