In addition, at the center of the bottom surface of the cylinder 110 of the container body 100, the lower end of the screw rod 200 is accommodated is provided with a groove 130 for guiding the screw rod 200 to rotate in place. In an embodiment of the present invention, but shown in the form that the lower end of the screw rod 200 is accommodated in the groove 130, but is not limited to this to protrude a plurality of ribs (not shown) in the center of the bottom of the cylinder (110) The lower end of the screw rod 200 may be rotatably supported.

The screw rod 200 is coupled to the rotary support portion 120 of the container body 100 so that the upper end is rotatably inserted through the cylindrical rotating member 210 and the lower end of the container body 100, that is, the groove 130. It is arranged to extend to the center. Cylindrical rotating member 210 is for mounting the upper end of the screw rod 200 to the rotation support portion 120 of the container body 100 to be idling, integrally formed on the upper end of the screw rod 200 and rotated on the outer wall A plurality of engagement protrusions 211 for tooth coupling with the cap 300 are provided at regular intervals. The screw rod 200 is processed with a screw thread having a constant pitch along the outer circumference, the discharge passage 220 is formed in the longitudinal direction therein. Therefore, the cosmetic liquid (L) is able to escape to the outside through the discharge flow path 220 of the screw rod 200.

And the piston unit 400 is to be mounted in the middle of the screw rod 200 by the screw coupling method, the cylinder of the container body 100 as the screw rod 200 is rotated in the forward direction together with the rotating member 210 (110) While falling in close contact with the wall. To this end, the piston unit 400 is made of hard synthetic resin and the screw-hole 200 is a piston-body 410 is processed in the center portion so that the screw rod 200 is engaged with the piston-body 410 of the It is made to surround the bottom and side, the bottom of the through-hole 421 is perforated to penetrate the screw rod 200 and the outer wall is a soft contact member 420 in close contact with the wall surface of the cylinder 110 of the container body 100 Consists of The close contact member 420 constituting the piston unit 420 is preferably made of a silicon material excellent in adhesion to the wall surface of the cylinder (110). Therefore, when the screw rod 200 is idling in the forward direction (see the arrow direction in Figure 2) inside the container body 100, the piston unit 400 is lowered along the cylinder 110 wall surface of the container body 100 to the container The cosmetic liquid L stored in the main body 100 is discharged through the discharge passage 220 of the screw rod 200.

Rotating cap 300 is assembled to the rotation support portion 210 of the container body 100 to operate the screw rod 200 together with the rotating member 210, the center of the upper surface 310 of the screw rod 200 The outlet 311 is punctured to match the top end and the wall surface 320 is formed in a cup shape in which a lower portion is opened through a synthetic resin so as to cover the rotary support 120 of the container body 100 from the outside. The inner surface of the wall 320 of the rotating cap 300 is engaged with the rotating member 210 to rotate the screw rod 200 from the outside. The upper surface 310 of the rotary cap 300 is concave in a round shape, which is to facilitate the use of the discharged cosmetic liquid.

In addition, a rubber valve 500 (RUBBER VALVE) for opening and closing the outlet 311 is disposed at the outlet 311 of the rotary cap 300 by the cosmetic liquid L discharge pressure and its elastic restoring force. 4 and 5, the rubber valve 500 is made of a silicon material which is excellent in elastic restoring force and harmless to the human body, and is fixed to the wall 510 of the outlet 311 while being inserted and coupled to the fixing part 510. In addition, the cosmetic liquid L is defined as a valve-lip 520 covering the upper portion of the outlet 311 in the form of an outward flange at the upper end of the fixing part 510 so as to be discharged upward. In addition, the fixing portion 510 of the rubber valve 500 is formed to have a circular cross-section smaller than the diameter of the outlet 311, the lower end of the locking jaw 511 is provided with an expanded diameter. For placement of such a rubber valve 500; Engaging projections 312 are provided at regular intervals on the wall of the outlet 311, and the step groove 313 is recessed so that the edge of the valve-lip 520 of the rubber valve 500 can be seated around the top of the outlet 311. ) Is formed. Therefore, when the fixing part 510 of the rubber valve 500 is completely inserted from the upper side to the lower side, the locking jaw 511 is caught on the lower side of the locking protrusion 312 so as not to be released unless an artificial force is applied, and the valve-lip The edge 520 is seated in the stepped groove 313 to close the outlet 311. In addition, a ring-shaped discharge guide 330 is disposed below the outlet 311 of the rotary cap 300 to directly connect with the outlet 311 while surrounding the top end of the screw rod 200. The discharge guide 330 is also made of a silicon material, and directly guides the cosmetic liquid L discharged through the screw rod 200 discharge passage 220 to the discharge port 311.

Accordingly, when the screw rod 200 is rotated in the forward direction, the edge of the valve-lip 520 of the rubber valve 500 is upward by the discharge pressure of the cosmetic liquid L discharged through the discharge passage 220 of the screw rod 200. When the outlet 311 is opened and the screw rod 200 is stopped, the valve-lip 520 of the rubber valve 500 is restored by its elastic restoring force to close the outlet 311.

On the other hand, in order to prevent the cap 300 from falling out of the container body 100, as shown in Figures 3 and 4, the rim rim 140 in the circumferential direction on the wall surface of the rotation support portion 120 of the container body 100 ) Is provided to protrude, and the locking groove 340 to accommodate the engaging frame 140 is concave in the form of a strip on the lower inner wall of the rotary cap 300. Therefore, when the rotating cap 300 is inserted into the container body 100 by the upper portion, the rotating cap 300 is engaged with the rotating member 210 and at the same time, the locking frame 140 is coupled to the locking groove 340 by the uneven coupling method. To be combined. As a result, the rotation cap 300 may rotate the screw rod 200 in the forward and reverse directions together with the rotation member 210 without being separated from the upper portion of the container body 100.

In addition, between the lower surface of the wall 320 of the rotary cap 300 and the wall surface of the rotary support portion 120 of the container body 100, the click for rotating the rotation cap 300 appropriately in the forward direction to lower the piston unit 400 A member 600 (CLICK) is provided. The click member 600 is for recognizing the degree of rotation by holding the rotary cap 500 through the hearing and the rotation load, as shown in Figure 4 and 6, the rotation cap 300 of the wall surface 320 Four click teeth 610 provided to protrude at an interval of 90 degrees on the lower inner wall, and one click protrusion 620 protruded to be caught with the click teeth 610 on the outer wall of the rotation support part 120 of the container body 100. Consists of Four click teeth 610 are configured to have a 90-degree intervals inside the wall surface 320 of the rotating cap 300 to have a substantially triangular cross-section, so that each time the rotating cap 300 is rotated 90 degrees clip 610 One of the) bumps against the click protrusion 620 and makes a "click" sound.

Therefore, when the user applies a force to rotate the rotary cap 300, the clip tooth 610 can feel a slight load in the rotation operation while making a "click" sound every time the click projection 620 goes over. At this time, the lower end of the wall surface 320 of the rotary cap 300 is required a slight elastic deformation in the radial direction, which is possible because the rotary cap 300 is made of a synthetic resin that can be elastically deformed.

First, when the user wants to use the gel-type cosmetics, the over-cap 700 is separated from the container body 100.

In this state, as shown in FIG. 7, the container body 100 is held by one hand, and the rotating cap 300 is held by the other hand and rotated in a forward direction (arrow R direction).

In accordance with the forward rotation of the rotating cap 300, the screw rod 200 with the rotating member 210 is idling in the interior of the container body (100). Accordingly, the piston unit 400 is in close contact with the wall surface of the cylinder 110 and linearly descends along the screw line of the screw rod 200 to generate pressure in the cylinder 110, and thus the cosmetics filled in the container body 100. The liquid L exits to the rotation cap 300 side through the discharge flow path 220 of the screw rod 200 made of a hollow body.

That is, as shown in Figures 7 and 8, by rotating the rotary cap 300 in the forward direction (arrow R direction), the cosmetic liquid (L) is the edge of the valve-lip 520 of the rubber valve 500 It is discharged to the upper surface 310 of the rotary cap 300 through the outlet 311 while lifting upward. Therefore, the user can use by taking the cosmetic liquid (L) discharged to the upper surface 310 of the rotary cap 300.

And when the rotation of the rotating cap 300 is stopped; By its elastic restoring force, the valve-lip 520 of the rubber valve 500 is immediately restored to close the outlet 311. In addition, since the piston unit 400 in close contact with the wall of the cylinder 110 does not descend unless the rotary cap 300 is rotated arbitrarily, the cosmetic liquid L may leak even when the container body 100 is lifted upside down. Does not spill

Each time the rotary cap 300 is rotated 90 degrees or more, the click tooth 610 goes beyond the click protrusion 620 while making a "click" sound. Accordingly, the user can appropriately rotate the rotary cap 300 while listening to the "click" generated while the rotary cap 300 rotates, and prevents the cosmetic liquid L from being excessively spilled. . The click sound of the click tooth 610 as described above occurs even when the rotary cap 300 is operated 90 degrees or more in the reverse direction. Therefore, after using the rotary cap 300 is rotated by 1 to 2 clicks in the reverse direction, the negative pressure is generated and the cosmetic liquid (L) remaining in the upper portion of the screw rod 200 is sucked, thereby further cosmetic liquid ( L) Spill can be reliably prevented.

Meanwhile, in one embodiment of the present invention, the rubber valve 500 is inserted into the outlet 311 from the upper side to the lower side to open and close the outlet 311. As shown in FIGS. 9 and 10, the rubber valve 800 is shown. ) Can also be achieved in the type fitted in the lower portion of the outlet 311 can achieve the desired object of the present invention. That is, the rubber valve 800 according to another embodiment of the present invention is inserted into the outlet from the bottom to the outlet 311 of the rotary cap 300 and is cut in the center so as to be branched to open the cosmetic liquid (L) discharge pressure. 811 and the valve portion 810 is formed, and extending from the lower end of the valve portion 810 in the form of outward flange wraps close to the upper surface 310 of the rotating cap 300 while wrapping the upper end of the screw rod 200 It consists of a fixed portion 820.

Therefore, as shown in FIG. 11, the cosmetic liquid L discharged through the discharge passage 220 of the screw rod 200 rotates the cutout groove 811 of the rubber valve 800 at the discharge pressure. 300 is discharged to the upper surface 310. And when the cosmetic liquid (L) is not discharged, the cutout groove 811 of the rubber valve 800 is immediately restored to its elastic restoring force to close the outlet 311. The rubber valve 800 according to another embodiment of the present invention is also excellent in elastic restoring force and is preferably composed of a silicon material harmless to the human body.
