    The present invention relates to the closure structure for a container of cosmetic products, which comprises a coupling element formed on the circumferential surface inside said container, with a female screw mechanism, so that this mechanism can engage in the male screw portion formed on the circumferential surface outside the aperture, which is formed in the upper portion of the container which receives the liquid. More particularly, the pipette tube can be inserted into the high viscosity liquid contained in the container after unloading air from inside the pipette tube. The high viscosity liquid may be drawn into said pipette tube in a required amount by previously preventing the expelled air from re-entering it.
    In general, the pipette is a dispensing device used to discharge the liquid to a desired location after it has been sucked by a suction action by pumping the pipette. By compressing the tubular pumping piece having a high elastic force and an inverted "U" shape, the air is discharged from an inner portion of the pipette tube coupled to a lower end of the pumping portion. When the elastic restoring force is generated after the pumping portion has been compressed, the air or liquid phase content is drawn into the pipette tube. Then the liquid is discharged by compressing the pumping part again.
    In order to aspirate and evacuate the liquid contents of the container, the pipette tube is introduced into the container and the pumping portion is compressed to discharge air from the inner portion of the pipette.
    Then, when the pumping portion is compressed and the compressive force of the pumping portion is released, the liquid received in the container is drawn into the pipette tube using the elastic restoring force of the pumping portion and this content is unloaded at the location desired by the user, so that the user can only use the required quantity.
    In this case, since the contents received in the container represent a lower viscosity and excellent fluidity when the air is discharged from the inner part of the pipette tube, the discharged air creates bubbles in the contents and floats rapidly, this causes the liquid to approach an opening formed at the lower end of the pipette tube, and thus, it is sucked into this tube via a suction action.
    However, as shown in Figure 1, when the liquid content received in the container 1 represents a higher viscosity, its fluidity is reduced. Accordingly, when the pumping portion 3 is compressed to evacuate air from the inner portion of the pipette tube 2, which is introduced into the liquid, then the discharged air does not float after forming a layer of air in the liquid contents, but remains around a discharge port 2a at the lower end of the pipette tube 2 while mounting slowly.
    Therefore, when the user compresses the pumping portion 3 and immediately releases the compressive force, the air remaining around the discharge port 2a is sucked into it, and thus the liquid can not be sucked in. sweetness in sufficient quantity.
    The present invention consists in solving the problems encountered above by a closure system of the cosmetic container capable of sucking the high-viscosity liquid without being disturbed by the air discharged by preventing the air from being sucked into the internal part. pipette tube after it is inserted into the liquid.

    The structures and operations of the present invention will be described with reference to Figures 2 and 5 E. Figures 2 to 3E show a first embodiment, and Figures 4 and 5E describe a second embodiment. Next, the structure and operation will be described according to each embodiment.
    First, we will describe the common structure of the cap of the container of the cosmetic product on the basis of the present invention, and then will describe different structures and operations according to the first embodiment and the second embodiment.
    Common structures in the first and second embodiments.
    The male screw piece (102a) is formed at the opening portion (102) in the upper end of the cosmetic container (100), while the female screw piece (212) is formed on the circumferential surface inner portion of the lower portion of the coupling member (210) so that the male screw piece can be coupled with the female screw piece. In addition, the pipette tube (220) in tubular structure is inserted into the end of the opening hole (102b) which is formed in the opening portion of said container. As shown in Figure 2, the pipette tube has a coupling protrusion (222) projecting from the upper outer portion thereof in the circumferential direction.
    According to the present invention, the pumping unit is arranged to discharge the inner air of the pipette tube as it enters the container through the opening hole (102b) of the opening portion (102). ) and draws the contents into the container (100).
    As shown in Figure. 2, the tube of the pipette (220), which is coupled with the coupling element (210), is inserted into the opening hole, this insertion operation stops and is maintained in an intermediate portion of the tube of the pipette and, after discharging the internal air, it is reinserted into said container, through the opening hole, to suck the contents.
    In other words, in the pumping unit, a cylinder (214) having the open top protruding from the upper end of the coupling member (210), the through hole (216) is formed vertically, from so that the bottom of the cylinder can communicate with the inner portion of the female screw (212), the upper end of the pipette tube (220), so that said coupling projection (222) can be inserted to the high from the bottom of the through hole.
    In addition, as shown in Figure. 2, the lower piston (230) is inserted into the cylinder (214), so that the outer circumferential surface of the lower piston (230) can slide in close contact with the inner circumferential surface of the cylinder (214). The coupling hole (232) is formed vertically in the lower piston (230) and the coupling groove (234) is formed around the lower inner circumferential surface of the coupling hole (232), so that the projection of coupling (222) of the pipette tube (220) can be inserted into the coupling groove forming the coupling structure.
    As shown in Figure 2, the upper piston (240) fits into the cylinder, i.e. the upper part of the lower piston (230), so that the outer circumferential surface of the upper piston can slide in close contact with the inner circumferential surface of the cylinder, this is also the case for the lower piston (230).
    In addition, the pressure member (250) covers the upper outer portion of the cylinder (214) such that the coupling portion (252) formed at the bottom of the pressure member can be coupled to the upper piston (240). . Accordingly, if the pressure member is pressed downward, the upper piston can slide down into close contact with the inner circumferential surface of the cylinder (214).
    In addition, as shown in Figure. 2, the mounting portion (218) is formed in any lower outer portion of the cylinder (214) in the upper end of the coupling member (210). The resilient member (260), which is inserted into the outer portion of the cylinder (214), securely attaches to the mounting portion (218), and thus, the upper end of the resilient member resiliently supports the member pressure (250). As a result, the latter presses the upper piston (240) downwards and rises by the elastic force of the elastic element.
    In addition, the cover member (270) is inserted down into the outer portion of the pressing member (250) and unites with the outer circumferential surface of the coupling member (210).
    In this case, the cover member has the upper inner portion narrower than the lower inner portion and the pressure member has the lower outer portion wider than the upper outer portion. Accordingly, the cover member, being in close contact with the lower outer portion of the pressure member, can prevent the pressure member from separating from the cover member, and thereby the element coupling and the elastic member (260), mounted on the pressure member, can be maintained in an elastic state by the pressure member and the cover member.
    As described above, from the first embodiment to the fifth embodiment of the cosmetic product container cap in the context of the present invention have a common structure of the coupling member (210) which is coupled to the container (100). ), the cylinder (214) and the pipette tube (220) formed in the upper part of the coupling element, the lower piston (230), the upper piston (240), the pressure element (250) , the resilient member (260) and the cover member (270), except for the design of the stopper holding member (280) of the pipette tube which will be described below. Hereinafter, the structure and operation of the stopper holding member of the pipette tube will be described.
    First embodiment of the stop holding member (280) of the pipette tube (220).
    The plug (282) is coupled to the upper end of the opening portion (102) of the container (100) and the stop hole (282a) is formed vertically through the shutter (282). . Therefore, when the tube of the pipette (220) is forced down therein. In this case, the inside diameter of the stop hole is equal to or greater than the outside diameter of the pipette tube, so that it can fit by pressure in the stop hole. In addition, if a user presses said pressure member (250) stronger than usual by forcing insertion of the pipette tube downwards, the latter is inserted through the stop hole.
    Second embodiment of the stop holding member (280) of the pipette tube (220).
    Although the second embodiment has the same configuration as that of the first embodiment, the inner surface of the stop hole (282a) is formed in a structure such as the wide top and the narrow bottom, so that only the lower portion of the stop hole (282a) can fit tightly around the outer portion of the pipette tube (220).
    Third embodiment of the stop holding member (280) of the pipette tube (220).
    As shown in Figure. 2, the shutter (282) is coupled to the upper end of the opening portion (102) of the container (100). the shutter is formed inside the stop hole (282a), so that the pipette tube (220) can be inserted into the insertion hole (282b) through it. The first stop protrusion (282c) protrudes from the inner circumferential surface of the insertion hole so that the pipette tube is forced downward by the force.
    Fourth embodiment of the stop holding member (280) of the pipette tube (220). The shutter (282) is formed with the insertion hole (282b) so that the pipette tube (220) can be inserted into the insertion hole (282b) through it and coupled to the insertion hole (282b). upper end of the opening portion (102) of the container (100). As shown in Fig. 5, the second stopper projection (224) projects outwardly from the outer circumferential surface of the pipette tube so that it can closely interfere with the inner circumferential surface of the insertion hole so as to adjust by pressure.
    Fifth embodiment of the stop holding member (280) of the pipette tube (220). The shutter (282) coupled to the upper end of the opening portion (102) of the container (100) in a manner similar to that of the fourth embodiment described above, and is formed in the insertion hole (282b), on the other hand, the outer circumferential surface of the pipette tube (220) is formed in several steps as shown in Figure 5.
    In other words, again according to FIG. 5, the insertion portion (226), having a narrower outer diameter with respect to the diameter of the insertion hole (282b), is formed at a predetermined distance from the end bottom of the pipette tube (220), so that it can pass freely through the insertion hole. The threading portion (228) having an outer diameter equal to or greater than the diameter of the inner circumferential surface of the insertion hole (282b) is formed above the insertion portion of the pipette tube, so that only the threading portion (228) can be inserted into the insertion hole (282b) forcing therethrough.
    Next, the operation of the cosmetic product container cap according to the present invention having the above configuration will be described with reference to Figures 2 and 5E.
    Figures 2 and 3E show the third embodiment of the present invention. Since the description made in the first embodiment and the second embodiment is substantially identical to that of the third embodiment of the description, therefore only the third embodiment will be described in a representative manner herein. below.
    Figure 2 shows the tube of the pipette (220) before the pipette (220) fits into the stop hole (282a) of the shutter (282) initially coupled to the opening portion (102). When a user inserts the pipette tube into the stop hole by grasping the pressure member (250) and the cover member (270) in the hand, the outer circumferential surface of the pipette tube (220) interferes with the first protruding protrusion (282c) of the inner circumference of the abutment hole (282a), so that the insertion operation of said pipette tube can temporarily stop and remain stopped .
    The cylinder (214), the coupling member (210), the pressure member (250) and the cover member (270) descend to the state where the inner circumferential surface of the cylinder (214) is in contact narrow with the outer portion of the lower piston (230). Accordingly, as shown in Figure 3b, the lower surface of the upper piston (240) contacts the upper surface of the lower piston (230), so that air can be discharged from the inner portion of the piston tube. pipette (220).
    In this case, if the user presses a little more on the pressure element (250), the coupling portion (252) of the pressure element (250) comes into contact with the upper piston (240) and the lower piston (230), and thus, the upper end of the pipette tube (220) can be coupled to the lower piston (230). Accordingly, since the pressure on the pressure element (250) is transmitted in the same way to the pipette tube (220), the latter stopped and held by the shutter (282), descends with the first stop projection (282c), as shown in Figure 3c. In this case, the coupling element (210) stops and is held in stop by the opening portion (102), so that the descent of the pipette tube can stop.
    If the user presses the pressure element (250) more strongly, since the coupling element (210) interferes with the opening portion (102), the pressure element compresses the element resilient (260), and thereby the upper piston (240) and the lower piston (230) can descend into the cylinder (214). In this case, as shown in Figure 3c, the air layer formed at the lower portion of the lower piston will be discharged through the through hole (216) of the coupling member.
    After releasing the pressing force on the pressure member (250), the pipette tube (220) is inserted into the container (100) as described above, since the tube the pipette (220) stops and is held in stop by the first stop projection (282c), the pressure member (250) rises by the elastic return force of the elastic member (260) and the upper piston (240) rises at the same time, so that the contents of the container can be sucked into the tube of the pipette (220).
    As a result, the user lifts the pipette tube (220) after grasping the lid member (270), and after that, separates the pipette tube from the stop hole (282a). Then, it presses the pressure member (250) again to discharge the contents of the inner portion of the pipette tube.
    In the first and second embodiments, the stop hole (282a) can be forced into the pipette tube (220) without the first stopper (282c). Accordingly, the description of operation in the third embodiment replaces that of the first and second embodiments.
    However, Figure 4 shows the fourth embodiment and the fifth embodiment of the present invention. As shown in Figure. 4, the fifth embodiment is shown in FIGS. 4 and 5E, and the operating description of the fourth embodiment will be substituted by the operation of the structure of the second projecting protrusion (224) projecting from the outer portion of FIG. tube of the pipette (220).
    According to the fifth embodiment, as shown in Figure 4, the outer portion of the pipette tube (220) is designed in a plurality of steps. The insertion portion (226) is designed such that the smaller diameter of the tube is smaller than that of the insertion hole (282b), so that the pipette tube can freely fit or to separate from the insertion hole (282b). The threading portion (228) formed above the insertion portion of the pipette tube has an outer diameter equal to or larger than the inside diameter of the insertion hole, so that the pipette tube can interfere with the insertion hole (282b) of the shutter (282).
    Accordingly, if the pipette tube (220) fits into the insertion hole (282b), the insertion portion (226) can freely fit into the insertion hole without interference with it, such as shown in Figure 5A, the threading portion (228), formed above the insertion portion interfering with the insertion hole, stops and is kept in a stall.
    In this case, if the user presses a little more on the pressure element (250), the cylinder (214) drops into the state where its inner circumferential surface is in close contact with the outer circumferential surface of the lower piston ( 230). As a result, the upper surface of the lower piston (230) comes into close contact with the upper piston (240), as shown in FIG. 5B, so that air can be discharged from the inner part of the pipette tube ( 220).
    In addition, if the user presses on the pressing member (250), since the coupling portion (252) thereof is coupled to the upper piston (240), the lower piston (230) closely engages the contact with the upper piston and thus, the upper end of the pipette tube (220) is coupled to the lower piston, the pipette tube descends until the coupling member (210) interferes with the opening portion (102) in the state where the threading portion (228) of the pipette tube can be inserted into the insertion hole (282b) by pressure, as shown in Figure 5C.
    In addition, according to Figure 5D, if the user presses the pressure member (250) a little further, the pressure member (250) compresses the elastic member (260) while pressing down the upper piston (240) and the lower piston (230), so that the latter can descend to the bottom of the cylinder (214).
    In this case, according to Figure 5C, the air layer formed at the bottom of the lower piston (230) will be discharged through the through hole (216) of the coupling member (210).
    As a result, and according to FIG. 5D, when the pressure of the pressure element (250) is released after the lower piston (230) descends to the bottom of the cylinder (214), in this case, as shown in FIG. Figure 5E, the pressure member and the upper piston (240) mount by the elastic return force of the elastic member (260) and the contents are sucked into the tube of the pipette (220).
    Therefore, the user separates the pipette tube from the insertion hole (282b) by lifting it after grasping the lid member (270) and pressing the pressure member (250) again, so the contents are discharged from the inner part of the pipette tube.
    In the fourth embodiment, the tube of the pipette (220) is forced into the insertion hole (282b) by the second stop projection (224) in the state where only the latter is formed on the outer part of the tube. Accordingly, the description of the operation in the fourth embodiment can be replaced by the description presented in the fifth embodiment.
