At this time, the above-mentioned cosmetic container 110 is formed as a containing space 111 for containing the liquid cosmetic C and opening upwards inside, and is formed integrally with the engaging protruding part on the outside of the upper part.

On the one hand, the above-mentioned cover 120 is combined with the upper end of the above-mentioned cosmetic container 110 in order to open and close the above-mentioned containing space 111 .

At this time, the above-mentioned cover 120 is inserted into the above-mentioned engaging protruding portion 113 at its lower part to form an engaging connecting groove portion 121 that opens upward on the inner side and forms a guiding groove 123 having an engaging tenon 122 on the inner surface.

As a result, the guide groove 123 has an elongated groove portion 124 having a smaller inner diameter than the guide groove 123 at its lower portion. At the lower end of the above-mentioned elongated groove portion 124, a blocking plate 126 having a fitting groove 125 is formed.

In addition, a through groove 127 communicating with the storage space 111 is formed on a side adjacent to the mounting groove 125 . In the center of the mounting groove 125, the liquid cosmetic C in the containing space 111 is integrally formed with a moving outflow tube 128.

At this time, an extension tube 129 extending the length of the outflow tube 128 is inserted into the outflow tube 128 .

On the other hand, the discharge amount limiting cap 130 communicates with the outflow tube 128 in order to control the movement amount of the liquid cosmetic C that moves through the outflow tube 128 , opens downward, and is attached to the mounting groove 125 .

At this time, the discharge amount limiting cap 130 has a semicircular arched portion 131 formed on its upper portion, and a pair of first discharge cut-out holes 133 are formed in the arched portion 131 .

Furthermore, between the pair of first discharge incision holes 133, in order to prevent the first discharge incision holes 133 from spreading excessively, an integral 0.2 mm wide connecting portion 135 is formed.

On the one hand, the pressurized discharge port 140 is connected to the guide groove 123 for generating compressed air necessary for discharging cosmetics in the guide groove 123, and can move up and down.

At this time, the above-mentioned pressurized discharge port 140 protrudes from its lower outer cylindrical surface to form a mortise joint portion 141 that is engaged with the above-mentioned joint tenon 122, and forms a discharge channel 143 for the movement of cosmetics on the inner side. , forming the engaging groove 145 .

On the other hand, the above-mentioned elastic recovery cap 150, in order to guide the inflowing liquid cosmetic C to the discharge channel 143 through the discharge amount limiting cap 130, and at the same time make the pressurized discharge port 140 that moves downward can be restored to its original shape by elastic force, and is pushed downward. The opening is installed between the above-mentioned discharge amount restricting cap 130 and the pressurized discharge port 140 .

At this time, the above-mentioned elastic restoration cap 150 forms a single tenon part 151 closely contacting the inner diameter of the above-mentioned elongated groove part 124 at its lower part, and on one side of the above-mentioned single tenon part 151, compressed air flows into the storage space 111- On the side, a mortise groove portion 153 having a wide top and a narrow bottom is formed.

At this time, the lower end of the above-mentioned mortise groove part and the upper end of the cut groove 155 form the same height with each other. The height of the side surface 157 is preferably 0.2 to 0.3 mm.

Thus, if the height of the above-mentioned side wall 157 is 0.2 mm, the compressed air flowing to the mortise groove portion 153 can be discharged again; if the height is above 0.3 mm, the flow of compressed air will be hindered. inflow. Therefore, the optimum height for the inflow and blocking of compressed air is in the range of 0.2-03 mm.

In addition, the elastic restoration cap 150 has a second discharge cut-out hole 159 in order to discharge the liquid cosmetic C flowing into the upper portion thereof.

At this time, it is preferable that the second discharge cut hole 159 is cross-shaped.

Thus, let's take a look at the combination relationship of the utility model with the above-mentioned structure—the suction nozzle for the liquid cosmetic container.

First, the engaging protrusion portion 113 of the above-mentioned cosmetic container 110 is inserted into the engaging groove portion 121 of the cap 120 to form engagement. Thus, the above-mentioned cosmetic container 100 and the cover 120 form a strong connection relationship that is not easy to be detached.

Then, the discharge amount limiting cap 130 is installed in the mounting groove 125 of the cover 120 , and the elastic recovery cap 150 is installed on the upper portion of the discharge amount limiting cap 130 .

Then, to the guide groove 123 of the above-mentioned cover 120, a pressurized discharge port 140 capable of moving up and down is connected.

At this time, the engaging tenon 122 of the guide groove 123 is engaged with the tenon protruding portion 141 of the pressurizing outlet 140 . The upper end of the elastic recovery cap 150 is inserted into the connecting groove 145 of the pressurized discharge port 140 to form a connection.

As a result, the pressurization discharge port 140 does not come out of the guide groove 123 even when it moves up and down, thereby forming a tight connection.

On the one hand, the suction nozzle for the liquid cosmetic container of the present invention is composed of the above-mentioned structure. The structure of the suction nozzle is simple, the production cost is reduced, and the required time is shortened at the earliest, and it can be mass-produced easily. The principle is explained in detail as follows.

Fig. 7a and Fig. 7b show the optimal operation state of the suction nozzle for the liquid cosmetic container of the present invention in practice.

As shown in FIG. 7 a : first, if the user presses the pressurized outlet 140 , the pressurized outlet 140 will slide along the guide groove 123 of the cover 120 to compress the air inside the guide groove 123 .

The compressed air generated at the same time flows to the lower end of the mortise groove portion 153 with the smallest contact surface in the single tenon portion 151 which is in surface contact with the inner surface of the elongated groove portion 124 .

At the same time, the compressed air flowing into the lower end of the mortise groove part 153 is formed by cutting the groove 155, pushes the side surface 157 which is in surface contact with the inner surface of the extension groove part 124, passes through the through groove 127, and flows into the containing space 111.

The compressed air thus moved into the storage space 111 acts on the liquid cosmetic C in the storage space 111 , and the liquid cosmetic C passes through the connecting pipe 129 , flows into the outflow pipe 128 and the discharge amount limiting cap 130 .

At the same time, the liquid cosmetic C flowing to the discharge amount limiting cap 130 cuts the first discharge cut hole 133 formed on the discharge limit cap 130 and the second discharge cut hole 133 formed on the elastic recovery cap 150 depending on the pressure. The hole 159 is divided, and is discharged into the user's hand through the discharge channel 143 of the pressurized discharge port 140 . At the same time, the elastic recovery cap 150 is pressurized through the pressurization outlet 140 to bend its outer diameter into an arc shape.

Then, when the user releases the pressure from the pressurized discharge port 140, as shown in FIG.

At this time, external air flows in through the minute gap between the pressurized discharge port 140 and the guide groove 123 , and an atmospheric pressure state is formed inside the guide groove 123 .

And, although the compressed air flowing into the containing space 111 of the above-mentioned cosmetic container 110 wants to come out from the inside, a part of the compressed air flows into the cut groove 155 and pressurizes the side wall 157, so the compressed air cannot come out from the cosmetic container 110.

Therefore, the liquid cosmetic C in the cosmetic container 110 is spit out into the hands of the user, the holding space 111 is enlarged by the amount of the liquid cosmetic C reduction, and the pressure of the inflowing compressed air is reduced, making it impossible to spit out more.

Therefore, the user can obtain a desired amount of liquid cosmetic according to the number of pressurization times of the pressurization discharge port 140 .

Thus, the suction nozzle for the liquid cosmetic container of the present invention, through the above actions, the user can easily obtain the desired amount of liquid cosmetic, the structure is simple, the manufacturing cost is reduced, and the time required for manufacturing is shortened. Can be easily mass-produced.
