Description

Technical Field

[0001] The present invention relates to a double twist structure and an article entry and exit mechanism including the structure and its sealing structure, and in particular to a double twist structure that can be used to lead out or introduce the nib (nib) or brush of a stick-shaped cosmetic or writing tool stored in a cylindrical and long pen-shaped barrel to the outside or inside through simple operation to improve ease of use, and can also use the double twist structure to move articles that need to be entered and exited to an accurate distance within an accurate time, and an article entry and exit mechanism including the structure and its sealing structure. Background Art

[0002] Generally speaking, women use various cosmetics to make themselves look more beautiful. For example, makeup cosmetics are used for the purpose of changing the appearance and shaping beautiful skin.

[0003] Makeup cosmetics are used to make skin tone more even and cover blemishes. They are divided into basic makeup and local makeup used to enhance the three-dimensional effect of parts such as lips, eyes and fingernails. Basic makeup is composed of primer, foundation and loose powder, while local makeup is composed of lipstick, eyeliner and mascara.

[0004] Recently, for the convenience of use and portability, a stick-shaped cosmetic container has been developed in which a stick-shaped cosmetic is mounted on one side of the container and the stick-shaped cosmetic mounted inside the container is raised and lowered by rotating the container.

[0005] A stick-shaped cosmetic container comprises: an outer shell; a lower cover formed with a lifting guide hole in the form of a thread; a working component that is lifted and lowered according to the rotation of the lower cover; a storage component that is coupled to the working component and has the stick-shaped cosmetic attached thereto; a protection tube that supports the lifting and lowering of the storage component and stores the stick-shaped cosmetic; and an upper cover that seals the protection tube.

[0006] When it is needed to use, the outer shell can be rotated while holding the protection tube so that the stick-shaped cosmetic can be extended from or inserted into the protection tube.

[0007] Although the content inlet and outlet structure of the existing stick-shaped cosmetic container is formed by a spiral structure, in order to draw out the pen tip to a required length for use, the upper cover and the lower cover need to be rotated several times, which causes a lot of inconvenience to the user.

[0008] In addition, writing instruments refer to signing pens, highlighters, and multi-purpose pens including ballpoint pens, and most of these writing instruments have a detachable sealing cap fixed thereto in order to prevent the writing core from drying out.

[0009] The writing tools described above generally include a fixed type in which the pen core is fixed and a cap (hereinafter referred to as the pen cap) is used, a rotating type (lead-out type) in which a part of the pen core is led out to the outside along a spiral tube by rotating a part of the shaft, a knocking type in which a spring is moved by pressing a part of the shaft to thereby lead out the pen core, and a slide type in which the pen core is protruded and sunk by sliding.

[0010] Although the pen-in-and-out writing instrument has the advantage of being able to be used directly without opening or closing the pen cap, since the pen core insertion and extraction hole is formed simply by perforating the end of one side of the writing instrument, it also has the problem of being limited to use in non-volatile or low-volatile writing instruments such as oil-based inks.

[0011] In contrast, although markers, white markers, water-based pens, and fluorescent pens with high volatility have the inconvenience of needing to open and close the pen cap, when the pen core is left in the air for a long time, the ink may dry out and the service life of the writing tool may be shortened or damaged.

[0012] Therefore, in order to solve the above-mentioned problems, Korean registered patent No. 10-1995-0000776 (a capless writing tool with an anti-drying structure) was proposed, which discloses a structure that can open the cap covering the pen core part by the tension of a rubber band when the pressing part of the input and output writing tool is pressed, and seal it when it is pressed again, thereby preventing the ink from drying out.

[0013] However, since the tension of the rubber band is used, the lid opening and closing action is not fast, there is room for improvement in durability, and the airtight state of the lid that temporarily closes the small hole is extremely unreliable.

[0014] In addition, in Korean Utility Model Registration No. 20-1989-0003644 (capless writing tool), when the knocking part is pressed, the pen tip can penetrate the elastomer installed in the inner tube and thereby expose the pen tip to the outside for use. When the knocking part is released or pressed again, the pen tip will return to its original position and the cut elastomers will contact and seal with each other, thereby preventing the pen tip from drying out.

[0015] However, the above-mentioned method may cause the problem of plastic deformation of the cut portion of the elastic body due to friction during frequent use, and the problem of reduced sealing force due to frequent friction.

[0016] In summary, the prior art described above has the problem that it is difficult to accurately adjust the moving distance and working time of the articles to be taken in and out according to the length of the shell for accommodating the articles and the movement of the opening and closing of the shell.

[0037] The cam pin 320 moves along the cam groove 120 and is inserted into and coupled to the first stopper 610 to limit the movement of the cam pin 320.

[0038] The fixing unit 600 includes:

[0039] A second stopper 620 is formed at one or more positions of one end or both ends of the twist cam groove 310 and protrudes toward the inner side of the twist cam groove 310;

Therefore, compared with the single twisting structure, the transfer distance and working distance of the content tube can be extended.

[0054] In addition, the inner tube will not work and remain in a stopped state while the ball valve is opening, thereby preventing the pen tip or brush from colliding. The pen tip or brush will only move after the ball valve is opened, thereby achieving a double twisting structure with one action.

[0055] In addition, the double twist structure can be used to link the contents and the ball valve when the working cover rotates, so that the movement time and movement distance required for the objects to enter and exit the shell can be accurately adjusted.

[0056] In addition, by simple operation, when the working cover is rotated, the contents and the ball valve can be linked to protrude to the outside of the shell or reset to the inside, thereby automatically completing the sealing and protecting the contents contained inside. The working cover can be prevented from rotating by a limiter and a magnet, while the user can recognize the rotation of the working cover and easily confirm whether it is sealed or not. The object entry and exit mechanism

[0057] In addition, the loss of sealing function or failure due to repeated use can be prevented in advance, thereby improving the reliability, convenience of use and commercial quality of the product. It can also prevent the contents from being damaged or drying out inside the casing during the operation of taking in and out, and can be stored more cleanly. BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 22 (a) and (b) are cross-sectional views showing a fixing unit according to still another embodiment of the present invention.

[0110] like Figures 1 to 22 As shown, the double twisting structure of the present invention and the article entry and exit mechanism including the structure and its sealing structure generally include an outer shell 100, a sleeve 200, a working tube body 300, a ball valve 400 and a working cover 500, so that the ball valve 400 can be opened and closed when the working cover 500 installed in a freely rotatable manner at the front end of the outer shell 100 is rotated, and at the same time, the content tube 110 stored inside is allowed to enter and exit the outside by means of the linkage between the sleeve and the working tube body 300.

[0111] Specifically, when the distance that the working tube body 300 moves through the cam groove 120 is referred to as the first moving distance L1 and the distance that the content tube 110 moves through the twisting cam groove 310 is referred to as the second moving distance L2, during the working period of the cam pin 320 of the working tube body 300 moving the distance through the inclined portion 121 of the cam groove 120 equipped in the outer shell 100, i.e., the first moving distance L1, the cam protrusion 210 will rotate under the guidance of the straight portion 311 of the cam groove 310, but its straight line motion, i.e., movement, will be in a stopped state.

[0112] Next, when the cam pin 320 reaches the straight portion 122 of the cam groove 120, the working tube body 300 will continue to rotate through the straight portion 122, but its straight motion, i.e., linear movement, will be in a stopped state, and during the period, the cam protrusion 210 will rotate and move linearly through the inclined portion 312 of the cam groove 310, thereby moving the second moving distance L2.

[0113] That is, the moving distances of the sleeve 200 and the content tube 110 will change according to the inclination angles of the inclined portion 121 and the inclined part 312 .

[0114] In addition, when the working cover 500 is rotated in the reverse direction, the working will be performed in the reverse order.

[0115] In addition, when the working cover 500 is rotated, the content tube 110 will first stop moving when the ball valve 400 is opened due to the movement of the first moving distance L1, and then after the ball valve 400 stops rotating in the open state, the content tube 110 will move the second moving distance L2 and protrude to the outside of the outer shell, and when the working cover 500 is rotated in the reverse direction, the working cover 500 will be closed and sealed by the first moving distance L1 after the content tube 110 first moves the second moving distance L2.

[0116] In summary, in the present invention, when the working tube body moves, the sleeve and the content tube will also move simultaneously, and when the working tube body stops, the sleeve and the content tube will further move and thereby extend the transfer distance. Therefore, compared with the single twisting structure, the transfer distance and working distance of the content tube can be extended, and during the working period when the ball valve is opening, the content tube will not work and remain in a stopped state, thereby preventing the collision of the pen tip or the brush, and the pen tip or the brush will only move after the ball valve is opened, so that the double twisting structure can be realized through one action.

[0117] In addition, when the ball valve 400 is closed, if volatile writing ink or contents such as stick-shaped cosmetics that may change color or deteriorate are stored in the content tube 110, it can play the role of preventing drying, discoloration and deterioration.

[0118] The housing 100 has a hollow cylindrical shape and is provided with a cam groove 120 at the front end in order to accommodate the content tube 110 having a small diameter and a long length inside.

[0119] The cam protrusion 210 can be rotated along the cam curve by being assembled to the twisted cam groove 310 of the working tube body 300, and at the same time, the inner tube 110 and the sleeve 200 can be advanced or retreated together by the second moving distance L2.

[0120] The cam groove 120 has a twisted shape and is formed in one or more portions along the cylindrical portion, and is composed of an inclined portion 121 and a straight portion 122 .

[0121] Therefore, when the cam pin 320 of the working tube body 300 is slidably engaged in the cam groove 120, when the working cover 500 described later is rotated, it will rotate along the inclined surface corresponding to the inclined portion 121, and the position of the working tube body 300 will advance or retreat a first moving distance L1 inside the housing 100.

[0122] Furthermore, when the working cover 400 is continuously operated after the cam pin 320 moves to a position corresponding to the straight portion 122 of the cam groove 120 , the working cover 500 continues to rotate, but the working tube body 300 does not move forward or backward.

[0123] In addition, a sleeve 200 is provided which is formed in a hollow cylindrical shape into which the content tube 110 can be inserted and coupled, and has a cam protrusion 210 integrally formed on the outer side.

[0124] It should be noted that the sleeve 200 and the content tube 110 described above can be manufactured in a separate type or in an integrated type.

[0125] The cam protrusion 210 is assembled to the twisted cam groove 310 of the working tube body 300 to rotate along the cam curve, while the inner tube 110 and the sleeve 200 are advanced or retreated together by the second moving distance L2.

[0126] The working tube body 330 is provided with a twisted cam groove 310 into which the cam protrusion 210 of the sleeve 200 can be embedded and slidably moved, and a cam pin 320 protruding at a position offset from the twisted cam groove 310 so as to be movable under the guidance of the cam groove 120 of the housing 100.

[0127] The twisted cam groove 310 is twisted in shape and is formed in one or more portions along a cylindrical portion, and is composed of a straight portion 311 and an inclined portion 312 .

[0128] Thus, when the cam protrusion 210 moves along the twisted cam groove 310 , the cam protrusion 210 cannot move in the forward direction in the straight portion 311 , but the cam protrusion 210 can move forward or backward together with the sleeve 200 after being located at the inclined portion 312 .

[0129] The reason why the straight portion 311 is formed in the twisting cam groove 310 as described above is to maintain the time difference when the ball valve 400 operates and opens and closes the through hole 430, thereby preventing the pen tip 111 of the content tube 110 that advances or retreats together with the sleeve 200 from contacting.

[0130] The cam protrusion 210 of the sleeve 200 is embedded through the inclined portion 312 , thereby causing the position of the working tube body 300 to move forward or backward along the cam curved surface inside the housing 100 by a second moving distance L2 .

[0131] The second moving distance L2 for advancing or retreating the sleeve 200 and the content tube 110 can be set to be relatively larger than the first moving distance L2 provided at the front end of the housing 100, or the first moving distance L1 can be set to be relatively larger than the second moving distance L2.

[0132] That is, the cam groove 120 of the housing 100 and the twisted cam groove 310 of the working tube body 300 both adopt a twisted shape, so the structure can be called a double twisted structure.

[0133] Specifically, the double twisting structure refers to a structure that is equipped with double cam grooves for converting rotational motion into linear motion, which can move the corresponding items an appropriate distance at the right time when the items are in and out, so that the end of the item can pass through the opening and closing mouth accurately.

[0134] More specifically, the double twisted structure refers to the cam groove 120 of the housing 100 and the twisted cam groove 310 of the working tube body 300 which will be described later.

[0135] In addition, by forming a guide groove 140 on the central inner side of the shell 100 along the axial center direction, that is, the entry and exit direction of the content tube 110, and embedding and assembling the guide protrusion 113 protruding from the content tube 110 into the guide groove 140, the sleeve 200 and the content tube 110 will not be able to rotate, but can only move forward or backward in a straight line.

[0136] In addition, a coupling protrusion 112 is formed to protrude at a position spaced a certain distance from the guide protrusion 113 and is embedded in a coupling groove 220 provided in the sleeve 200 .

[0137] In addition, by forming a single or multiple grooves 115 at the front end of the content tube 110 and forming a single or multiple protrusions 205 in the sleeve 200 to be combined with the grooves 115, the content tube 110 and the sleeve 200 can be tightly assembled to prevent them from being separated or moved from each other while achieving sealing.

[0138] In addition, as another embodiment, a guide protrusion 113 may be provided on the central inner side of the housing 100 , and a guide groove 140 for accommodating the guide protrusion 113 may be formed in the content tube 110 .

[0139] In the working tube body 300 , a pair of arms 330 are extended to form axial holes 331 at the front end portions of the arms 330 .

[0140] The arm 330 has a function of rotating the ball valve 400 .

[0141] The ball valve 400 is in the shape of a ball, and a center pin 410 is formed at the center and protrudes outwards on both sides.

[0142] In addition, eccentric pins 420 are protruded at eccentric positions spaced a certain distance from the center pin 410 .

[0143] The eccentric pin 420 is inserted and assembled into the shaft hole 331 of the arm 330 .

[0144] Furthermore, a through hole 430 is formed through the ball valve 440 so that the pen tip 111 of the content tube 110 can pass through the through hole 430 when the arm 330 moves to the frontmost position.

[0145] Thus, when the arm 330 moves forward or backward together with the working tube body 300, the ball valve 400 can control the position of the through hole 430 by rotating the position of the eccentric pin 420 around the center pin 410 at a specified position, thereby opening and closing the inlet and outlet channels.

[0146] The working tube body 300 can move forward or backward in the twisting direction under the guidance of the cam groove 120 provided in the housing 100.

[0147] In order to operate the working pipe body 300 and the sleeve 200 as described above, a working cover 500 is installed at the front end of the housing 100 .

[0148] The working cover 500 is in the shape of a hollow cylinder and is rotatably coupled to the front end of the housing 100 . The working cover 500 is recessed to form a guide groove 510 into which the cam pin 320 of the working tube body 300 can be slidably inserted.

[0149] In addition, if Fig.23 as well as Fig.24 As shown, the working cover plays a guiding role in causing the working tube body to rotate and move forward at the same time. In addition to the method in which the cam pin of the working tube body is embedded in the guide groove of the working cover to work (in the case of a rotating ball sealing structure), embodiments in which the working tube body is made to work and move forward by other methods as shown in the figure may also be applicable to the present invention.

[0150] In addition, in order to allow the housing 100 and the working cover 500 to rotate freely and prevent them from being separated, a blocking groove 130 is provided in the housing 100 , and a blocking protrusion 520 blocked by the blocking groove 130 is provided in the working cover 500 .

[0151] In terms of the anti-separation effect, the blocking groove 130 and the blocking protrusion 520 are preferably installed at multiple positions while maintaining a certain distance.

[0152] Thereby, even when the operating cover 500 is rotated, it will not be separated from the housing 100 .

[0153] In addition, a ball seat 440 made of an elastic material is installed inside the front end of the working cover 500 to support the rotation of the ball valve 400 , thereby sealing the ball valve 400 .

[0154] In addition, a support ring 450 is installed to allow the center pin 410 of the ball valve 400 to rotate around the center pin 410 when the center pin 410 is inserted into the pin hole 451, and a spring 460 for maintaining elastic force is installed between the support ring 450 and the housing 100.

[0155] It should be noted that, at this time, the support ring 450 and the working cover 500 can be manufactured in an integrated manner to reduce manufacturing processes and lower manufacturing costs.

[0156] The spring 460 can pressurize the ball valve 400 connected to the support ring 450 to make it close to the ball seat 440 and thereby prevent gaps from appearing around the ball valve 400, thereby maintaining a complete sealing effect inside the housing 100.

[0157] Among them, although the spring 460 and the housing 100 can be manufactured separately, it is preferable that the spring 460 and the front end of the housing 100 are manufactured in an integrated manner.

[0158] At this time, the spring 460 and the housing 100 can be made of a single material having elastic force, thereby achieving an economic effect of reducing manufacturing processes and lowering manufacturing costs.

[0159] At the inner front end portion of the working cover 500, a mounting portion 530 for mounting the support ring 450 and preventing the support ring 450 from moving is provided.

[0160] In addition, a notch groove 332 is formed at the inner end of the arm 330 for achieving free bending, so that when the arm 330 moves forward or backward and the position of the eccentric pin 420 rotates around the center pin 410, the ball valve 400 moves smoothly, especially in the up and down directions.

[0161] The front end of the content tube 110 having the above-mentioned structure can be equipped with a pen tip 111 or a brush, so that it can be used as an ink container for writing tools.

[0162] In addition, the pen tip 111 (nib) described in this specification refers to the pen tip formed in the pen, but it can also refer to a structure for transferring the content formed inside the content tube 110 to the outside of the article input and output mechanism. In addition, the structure described above can be in the form of a brush, and further can be in the form of a simple open mouth, a tube body, etc.

[0163] Alternatively, the content tube 110 may be used as a container for placing the contents of the stick-shaped cosmetic.

[0164] Figure 6 is a cross-sectional view of the assembled state of each component of the present invention, and Figure 7 Yes Figure 6 The structure of FIG. 1 is enlarged and the storage state in which the content tube 110 and the pen tip 111 are partially accommodated in the housing 100 is illustrated.

[0165] Figure 8The figure shows a usage state in which the content tube 110 and the pen tip 111 are partially exposed to the outside of the housing 100 in a state where the through hole 430 of the ball valve 400 is opened by rotating the operating cap 500 by about 180 degrees.

[0166] It should be noted that the working cover 500 can be rotated within a non-specific angle range according to the applicable field.

[0167] When the working cover 500 which is coupled to the front end of the housing 100 in a freely rotatable manner is rotated, the rotational force will be transmitted to the working tube body 300 and guided to the inclined portion 121 of the cam groove 120 provided in the housing 100 while the cam pin 320 is blocked by the guide groove 510, so that the working tube body 300 advances a first moving distance L1 while rotating.

[0168] Next, when the working cover 500 continues to rotate, the cam pin 320 will move along the straight portion, while the straight movement of the working tube body 300 will stop and rotate in place.

[0169] At the same time, the sleeve 200 and the inner cartridge 110 will work together along the twisted cam groove 310 provided in the working tube body 300 .

[0170] First, while the working body 300 is rotating and advancing, the cam protrusion 210 will be located at the straight portion 311 of the twisting cam groove 310, so the sleeve 200 and the content cartridge 110 coupled thereto will move the same distance as the moving distance of the working body 300.

[0171] At this time, the ball valve 400 will rotate and work when the working tube body 300 continues to move, and at the moment when the cam protrusion 210 is located at the inclined portion 312 connected to the straight portion 311, the content cylinder 110 combined with the sleeve 200 will quickly continue to move forward the second moving distance L2.

[0172] That is, the content cartridge 110 will continue to move along a straight line by the second moving distance L2 formed by the inclined portion 312 in a state where the rotation of the guide protrusion 113 is blocked by the guide groove 140 of the housing 100 .

[0173] Among them, because the second moving distance L2 is relatively longer than the first moving distance L1 and the moving distance of the content tube 110 combined in the sleeve 200 is relatively long, the pen tip 111 can be fully exposed to the outside of the working cover 500.

[0174] The guide groove 510 provided in the working cover 500 is recessed with a sufficient length in consideration of the moving distance of the cam pin 320 , and guides the linear movement in a state of preventing the cam pin 320 from being disengaged when the cam pin 320 rotates.

[0175] The arm 330 extending toward the front end of the working tube body 300 can move forward or backward in a state where the eccentric pin 420 of the ball valve 400 is inserted and assembled into the shaft hole 331, thereby switching the position of the through hole 430 while rotating the ball valve 400 to open and close ( Figure 8 as well as Fig.10 ).

[0176] In addition, when the working cover 500 is rotated to the original position, the sleeve 200 and the content tube 110 will first begin to retreat under the guidance of the inclined portion 312 in the opposite order to that described above, while the working tube body 300 will not be able to complete the position conversion action of the through hole 430 of the ball valve 400 within a certain period of time due to the straight portion 122 of the cam groove 120 formed on the outer shell 100.

[0177] In addition, from the moment the cam pin 320 is located at the inclined portion 121, the ball valve 400 will start to rotate again while the working tube body 300 and the arm 330 retreat together, and the through hole 430 will rotate relative to the moving direction of the pen tip 111, thereby returning to the state of maintaining the seal ( Figure 7 as well as Fig. 9 ).

[0178] Fig. 9 It is an enlarged cross-sectional view of a state before the operation of the working cover 500 is performed at a position where the cam protrusion 210 is assembled to the twisted cam groove 310 of the working tube body 300 .

[0179] Fig.10 This is an enlarged cross-sectional view showing a state in which the working tube body 300 , the sleeve 200 , and the pen tip 111 provided at the front end of the content tube 110 partially move forward and are exposed to the outside of the working cap 500 due to the rotation operation of the working cap 500 .

[0180] Figures 11 to 13 The working states of the working cover 500 , the sleeve 200 , and the ball valve 400 are illustrated by cutting the working cover 500 and the housing 100 by about 1 / 2.

[0181] Figures 14 to 16 The working states of the working cover 500 , the sleeve 200 , and the ball valve 400 are shown in perspective views by cutting only about 1 / 2 of the working cover 500 and the housing 100 .

[0182] Fig.17 as well as Fig.19The oblique view and the front view respectively show the position where the hole 430 blocks the direction perpendicular to the advancing direction of the pen tip 111 before the arm 330 provided on the working tube body 300 advances, that is, when connected to the ball valve 400.

[0183] Fig.18 as well as Fig.19 The perspective view and the front view respectively show a position where the through hole 430 is opened in the direction consistent with the advancing direction of the pen tip 111 in a state where the arm 330 provided on the working tube body 300 has advanced, that is, is connected to the ball valve 400.

[0184] The arm 330 may move up and down while advancing or retreating for the rotational movement of the eccentric pin 420 .

[0185] In addition, in order to prevent the pen tip 111 from partially drying out or volatile contents from evaporating, it is advisable to install a plurality of O-rings around the rotating component.

[0186] In addition, by using the spring 460 to pressurize the support ring 460 connected to the ball valve 400 so that the ball valve 400 is tightly attached to the ball seat 440, gaps can be prevented from appearing around the ball valve 400 and a complete sealing effect inside the housing 100 can be maintained for a long time.

[0187] By using the double twist structure of the present invention constructed as described above and the article inlet and outlet mechanism and the sealing structure including the structure, the content tube 110 can be used as a writing implement for storing volatile ink to prevent drying.

[0188] The latter can prevent discoloration and deterioration of contents such as stick-shaped cosmetics that may change color or deteriorate and maintain a clean state for a long time.

[0194] That is, the fixing unit 600 limits the movement of the cam pin 320 after the cam pin 320 moves toward the cam groove 120 and is embedded in the first limiter 610, thereby preventing the rotation of the working cover 500 and allowing the user to recognize the rotation of the working cover 500 and thereby easily confirm whether the article entry and exit mechanism is sealed.
