[0093] As illustrated in FIGS. 1 to 22, the present disclosure relates to a dual twist structure, an object ejecting device including the same, and a structure for sealing the same. The object ejecting device includes a housing 100, a sleeve 200, a tubular operation body 300, a ball valve 400, and an operation cap 500. When the operation cap 500 rotatably installed at a tip of the housing 100 is rotated, the ball valve 400 is opened, and the sleeve and the tubular operation body 300 operate in conjunction with each other, such that a content cartridge 110 accommodated in the housing 100 may be ejected to the outside.

[0094] In more detail, a distance by which the tubular operation body 300 is moved by a cam groove 120 is referred to as a first movement distance L1, and a distance by which the content cartridge 110 is moved by a twist cam groove 310 is referred to as a second movement distance L2. When a cam pin 320 of the tubular operation body 300 operates by the first movement distance L1 which is the distance by which the cam pin 320 is moved by an inclined portion 121 of the cam groove 120 provided in the housing 100, a straight portion 311 of the cam groove 310 allows the cam protrusion 210 to rotate by being guided by the straight portion 311 but stop performing the rectilinear motion, i.e., stop rectilinearly moving.

[0095] Thereafter, when the cam pin 320 reaches a straight portion 122 of the cam groove 120, the straight portion 122 allows the tubular operation body 300 to continuously rotate but stop performing the rectilinear motion, i.e., stop rectilinearly moving. At this time, the cam protrusion 210 is rotated and rectilinearly moved by an inclined portion 312 of the cam groove 310, such that the cam protrusion 210 may move by the second movement distance L2.

[0096] That is, motion distances of the sleeve 200 and the content cartridge 110 vary depending on inclination angles of the inclined portion 121 and the inclined portion 312.

[0097] In addition, when the operation cap 500 rotates reversely, the above-mentioned operation is performed in reverse order.

[0098] In addition, when the operation cap 500 is rotated, the content cartridge 110 stops moving first when the ball valve 400 is opened by the movement by the first movement distance L1. Then, after the operation cap 500 stops rotating in the state in which the ball valve 400 is opened, the content cartridge 110 moves by the second movement distance L2 and protrudes to the outside of the casing. When the operation cap 500 is rotated reversely, the content cartridge 110 moves by the second movement distance L2 first, and then the operation cap 500 is closed and sealed by the movement by the first movement distance L1.

[0099] As a result, according to the present disclosure, when the tubular operation body moves, the sleeve and the content cartridge simultaneously move. The sleeve and the content cartridge further move even though the tubular operation body is stopped, which increases the motion distance. Therefore, in comparison with a single twist structure, the motion distance and the operation distance of the content cartridge are increased. Further, during the operation time for which the ball valve is opened, the content cartridge is stopped without operating, which prevents a collision of a nib or a brush. Further, because the nib or the brush operates after the ball valve is opened, the dual twist structure may be implemented by the single operation.

[0100] Meanwhile, in the state in which the ball valve 400 is closed, it is possible to prevent volatile ink for a writing instrument stored in the content cartridge 110 or contents such as a stick cosmetic, which may be discolored or degenerated, from being dried, discolored, and degenerated.

[0101] The housing 100 has a cylindrical hollow shape to accommodate therein the content cartridge 110 having a small diameter and a long length and has the cam groove 120 formed at the tip thereof.

[0102] The cam protrusion 210 is assembled to the twist cam groove 310 of the tubular operation body 300. When the cam protrusion 210 rotates along a cam curve, the content cartridge 110 and the sleeve 200 may simultaneously move forward or rearward together by the second movement distance L2.

[0103] The cam groove 120 has a twisted shape and is provided in singular or plural along a cylindrical portion. The cam groove 120 includes the inclined portion 121 and the straight portion 122.

[0104] Therefore, when the operation cap 500 to be described below is rotated in the state in which the cam pin 320 of the tubular operation body 300 is slidably coupled to the cam groove 120, the tubular operation body 300 moves forward or rearward by the first movement distance L1 in the housing 100 while rotating along the inclined surface corresponding to the inclined portion 121.

[0105] Further, after the cam pin 320 is moved to the position corresponding to the straight portion 122 of the cam groove 120, the operation cap 500 rotates, but the tubular operation body 300 does not move forward or rearward, even though the operation cap 500 is continuously manipulated.

[0106] In addition, the sleeve 200 has a cylindrical hollow shape into which the content cartridge 110 is fitted and coupled, and the cam protrusion 210 integrally protrudes from an outer surface of the sleeve 200.

[0107] It is noted that the sleeve 200 may be manufactured separately from the content cartridge 110 or manufactured integrally with the content cartridge 110.

[0108] The cam protrusion 210 is assembled to the twist cam groove 310 of the tubular operation body 300. When the cam protrusion 210 rotates along the cam curve, the content cartridge 110 and the sleeve 200 simultaneously move forward or rearward together by the second movement distance L2.

[0109] The tubular operation body 300 includes: the twist cam groove 310 into which the cam protrusion 210 of the sleeve 200 is slidably fitted; and the cam pin 320 protruding and configured to move to a position misaligned with the twist cam groove 310 by being guided by the cam groove 120 of the housing 100.

[0110] The twist cam groove 310 has a twisted shape and is provided in singular or plural along the cylindrical portion. The twist cam groove 310 includes the straight portion 311 and the inclined portion 312.

[0111] Therefore, when the cam protrusion 210 moves along the twist cam groove 310, the cam protrusion 210 cannot move forward in the straight portion 311, but the cam protrusion 210, together with the sleeve 200, may move forward or rearward after the cam protrusion 210 is positioned in the inclined portion 312.

[0112] The reason why the straight portion 311 is formed in the twist cam groove 310 as described above is to maintain a time difference between the process of operating the ball valve 400 and the process of opening or closing the passing hole 430, thereby preventing the contact between the ball valve 400 and a nib 111 of the content cartridge 110 that moves forward or rearward together with the sleeve 200.

[0113] The cam protrusion 210 of the sleeve 200 is fitted with the inclined portion 312, such that the tubular operation body 300 moves forward or rearward by the second movement distance L2 along the cam curved surface in the housing 100.

[0114] In this case, the second movement distance L2 by which the sleeve 200 and the content cartridge 110 move forward or rearward may be relatively longer than the first movement distance L1 provided at the tip of the housing 100. Alternatively, the first movement distance L1 may be relatively longer than the second movement distance L2.

[0115] That is, both the cam groove 120 of the housing 100 and the twist cam groove 310 of the tubular operation body 300 each have the twisted shape, and the structure including the cam groove 120 and the twist cam groove 310 may be called the dual twist structure.

[0116] More specifically, the dual twist structure means a structure having two cam grooves that convert a rotational motion into a rectilinear motion, thereby moving the object by an appropriate distance and at an accurate time when ejecting the object, such that an end of the object accurately passes through an opening port.

[0117] More specifically, the dual twist structure includes the cam groove 120 of the housing 100 and the twist cam groove 310 of the tubular operation body 300.

[0118] Meanwhile, the guide groove 140 is formed at a center in the housing 100 in a direction of a center of an axis, i.e., a direction in which the content cartridge 110 is ejected. As the guide protrusion 113 protruding from the content cartridge 110 is assembled by being fitted into the guide groove 140, the sleeve 200 and the content cartridge 110 cannot rotate but can move forward or rearward only in the rectilinear direction.

[0119] Further, the coupling protrusion 112 protrudes at a position spaced apart from the guide protrusion 113 and is coupled and fitted into the coupling groove 220 provided in the sleeve 200.

[0120] In addition, a single groove 115 or a plurality of grooves 115 is formed in a tip portion of the content cartridge 110, and a single protrusion 205 or a plurality of protrusions 205 configured to be coupled to the groove 115 is formed on the sleeve 200.

[0121] Therefore, the content cartridge 110 and the sleeve 200 are tightly assembled and sealed so as not to separate from each other or move unintentionally.

[0122] In addition, according to another embodiment, the guide protrusion 113 may be formed at the center in the housing 100, and the guide groove 140 capable of accommodating the guide protrusion 113 may be formed in the content cartridge 110.

[0123] A pair of arms 330 extends from the tubular operation body 300 toward the tip portion and each has shaft holes 331.

[0124] The arms 330 serve to turn the ball valve 400.

[0125] The ball valve 400 has a ball shape and includes center pins 410 protruding outward from two opposite sides of a center position thereof.

[0126] Further, eccentric pins 420 protrude at eccentric positions spaced apart from the center pins 410 at a distance.

[0127] The eccentric pin 420 is assembled by being fitted into the shaft hole 331 of the arm 330.

[0128] Further, the passing hole 430 is formed in the ball valve 400 and disposed at a position at which the arms 330 are maximally moved to the tip of the ball valve 400 so that the nib 111 of the content cartridge 110 may pass through the passing hole 430.

[0129] Therefore, when the arms 330 move forward or rearward together with the tubular operation body 300, the ball valve 400 controls the position of the passing hole 430 by turning the eccentric pins 420 at the exact position about the center pins 410, thereby opening or closing the passageway.

[0130] The tubular operation body 300 simultaneously rotates in the twist direction and moves forward or rearward by being guided by the cam groove 120 provided in the housing 100.

[0131] The operation cap 500 is installed on the tip portion of the housing 100 to manipulate the tubular operation body 300 and the sleeve 200.

[0132] The operation cap 500 has a cylindrical hollow shape and is rotatably coupled to the tip of the housing 100. The operation cap 500 has a guide groove 510 into which the cam pin 320 of the tubular operation body 300 is slidably fitted.

[0133] Meanwhile, as illustrated in FIGS. 23 and 24, the operation cap serves as a guide that moves the tubular operation body while rotating the tubular operation body. An embodiment in which the tubular operation body is operated and moved forward in another manner may be applied to the present disclosure in addition to the embodiment in which the cam pin of the tubular operation body is operated by being fitted into the guide groove of the operation cap (a sealing structure having a rotary ball).

[0134] Meanwhile, to allow the housing 100 and the operation cap 500 to freely rotate and prevent the separation between the housing 100 and the operation cap 500, a catching groove 130 is formed in the housing 100, and a catching protrusion 520, which is caught by the catching groove 130, is formed on the operation cap 500.

[0135] It is advantageous in preventing the separation that the catching grooves 130 and the catching protrusions 520 are respectively installed at a plurality of positions while maintaining distances therebetween.

[0136] Therefore, the operation cap 500 does not separate from the housing 100 even though the operation cap 500 is turned.

[0137] Further, a ball seat 440 made of an elastic material is installed inside the tip portion of the operation cap 500 and supports the rotation of the ball valve 400, thereby sealing the ball valve 400.

[0138] In addition, a support ring 450 is installed to allow the ball valve 400 to be turned about the center pins 410 in the state in which the center pins 410 of the ball valve 400 are fitted into the pin holes 451. A spring 460 for maintaining elasticity is installed between the support ring 450 and the housing 100.

[0139] In this case, it is noted that the support ring 450 may be manufactured integrally with the operation cap 500 to reduce the manufacturing process and the manufacturing costs.

[0140] The spring 460 presses the ball valve 400 connected to the support ring 450 so that the ball valve 400 is in close contact with the ball seat 440, such that a gap is prevented from being formed at the periphery of the ball valve 400, thereby maintaining an effect of perfectly sealing the inside of the housing 100.

[0141] In this case, the spring 460 and the housing 100 may be independently manufactured. However, the spring 460 may be manufactured integrally with the tip of the housing 100.

[0142] In this case, the spring 460 and the housing 100 may be made of a single material having elasticity, thereby reducing the manufacturing process and the manufacturing costs and improving the economic effect.

[0143] An installation part 530 is provided inside the tip portion of the operation cap 500, and the support ring 450 is seated on the installation part 530 and prevented from being moved unintentionally.

[0144] In addition, a notch groove 332 is formed at an inner end of each of the arms 330 so that the arms 330 are freely bent. Therefore, the ball valve 400 may smoothly move even in an upward/downward direction during the process in which the ball valve 400 turns the eccentric pins 420 about the center pins 410 as the arms 330 move forward or rearward.

[0145] The nib 111, a brush, or the like is installed at the tip of the content cartridge 110 structured as described above, such that the content cartridge 110 may be configured as an ink container for a writing instrument.

[0146] In addition, the nib 111 disclosed in the present specification means a pen point. Further, the nib 111 may mean a component capable of transmitting the contents, stored in the content cartridge 110, to the outside of the object ejecting device. In addition, the nip 111 may be provided in the form of a brush, a simple opening, a tube, or the like.

[0147] Alternatively, it is noted that the content cartridge 110 may be configured as a container that accommodates stick cosmetic contents.

[0148] FIG. 6 is a cross-sectional view illustrating a state in which the respective components of the present disclosure are assembled, and FIG. 7 is an enlarged view of FIG. 6, which illustrates a state in which the content cartridge 110 and the nib 111 are accommodated and stored in the housing 100.

[0149] FIG. 8 illustrates a state in which the content cartridge 110 and the nib 111 are exposed to the outside of the housing 100 and used in a state in which the operation cap 500 is rotated by about 180 degrees and the passing hole 430 of the ball valve 400 is opened.

[0150] In this case, it is noted that the operation cap 500 may be rotated within a range of angle, which is not predetermined, depending on the field to which the object ejecting device is applied.

[0151] When the operation cap 500 rotatably coupled to the tip portion of the housing 100 is turned, the rotational force is transmitted to the tubular operation body 300 in the state in which the cam pin 320 is caught by the guide groove 510, and the tubular operation body 300 moves forward by the first movement distance L1 while rotating by being guided by the inclined portion 121 of the cam groove 120 provided in the housing 100.

[0152] Further, even though the operation cap 500 continuously rotates, the cam pin 320 moves along the straight portion 122, such that the tubular operation body 300 stops rectilinearly moving and only rotates at the same position.

[0153] At the same time, the sleeve 200 and the content cartridge 110 operate together along the twist cam groove 310 provided in the tubular operation body 300.

[0154] First, during the process in which the tubular operation body 300 moves forward while rotating, the cam protrusion 210 is positioned in the straight portion 311 of the twist cam groove 310. Therefore, the sleeve 200 and the content cartridge 110 coupled to the sleeve 200 move together by a distance equal to the movement distance of the tubular operation body 300.

[0155] In this case, the continuous movement of the tubular operation body 300 turns the ball valve 400. At the moment when the cam protrusion 210 is positioned at the position on the inclined portion 312 connected to the straight portion 311, the content cartridge 110 coupled to the sleeve 200 quickly moves forward by the second movement distance L2.

[0156] That is, in the state in which the guide groove 140 of the housing 100 prevents the guide protrusion 113 from rotating, the content cartridge 110 further rectilinearly moves forward by the second movement distance L2 defined by the inclined portion 312.

[0157] In this case, the second movement distance L2 is relatively longer than the first movement distance L1, and the movement distance of the content cartridge 110 coupled to the sleeve 200 is relatively long, such that the nib 111 may be sufficiently exposed to the outside of the operation cap 500.

[0158] The guide groove 510 provided in the operation cap 500 is recessed to have a sufficient length in consideration of the distance by which the cam pin 320 moves. The guide groove 510 guides the rectilinear movement while preventing the separation when the cam pin 320 rotates.

[0159] The arms 330 extending toward the tip portion of the tubular operation body 300 move forward or rearward in the state in which the eccentric pins 420 of the ball valve 400 are fitted with and assembled to the shaft holes 331, such that the arms 330 may turn the ball valve 400 and shift the position of the passing hole 430 to open or close the passing hole 430 (see FIGS. 8 and 10).

[0160] In addition, when the operation cap 500 is rotated to the original position, the sleeve 200 and the content cartridge 110 begin to be retracted first in reverse order by being guided by the inclined portion 312, and the operation of the tubular operation body 300 shifting the position of the passing hole 430 of the ball valve 400 cannot be performed by the straight portion 122 of the cam groove 120 formed in the housing 100.

[0161] Further, from the moment when the cam pin 320 is positioned in the inclined portion 121, the tubular operation body 300, together with the arms 330, is retracted, the ball valve 400 also begins to be turned, and then the passing hole 430 is rotated in the movement direction of the nib 111, such that the ball valve 400 is returned to maintain the sealed state (see FIGS. 7 and 9).

[0162] FIG. 9 is an enlarged cross-sectional view illustrating a state immediately before the operation cap 500 is manipulated at a position at which the cam protrusion 210 is assembled to the twist cam groove 310 of the tubular operation body 300.

[0163] FIG. 10 is an enlarged cross-sectional view illustrating a state in which the tubular operation body 300, the sleeve 200, and the nib 111 provided at the tip of the content cartridge 110 are moved forward by the rotation of the operation cap 500, and the nib 111 is exposed to the outside of the operation cap 500.

[0164] FIGS. 11 to 13 illustrate operating states of the operation cap 500, the sleeve 200, and the ball valve 400 in a state in which the operation cap 500 and the housing 100 are cut by about 1/2.

[0165] FIGS. 14 to 16 are perspective views illustrating operating states of the operation cap 500, the sleeve 200, and the ball valve 400 in a state in which only the operation cap 500 and the housing 100 are cut by about ½.

[0166] FIGS. 17 and 19 are perspective views and a front view illustrating a position at which the passing hole 430 is closed in a direction perpendicular to the direction in which the nib 111 moves forward in a state in which the arms 330 provided on the tubular operation body 300 are connected to the ball valve 400 in a state immediately before the arms 330 move forward.

[0167] FIGS. 18 and 20 are a perspective view and a front view illustrating a position at which the passing hole 430 is opened in a straight line with respect to the direction in which the nib 111 moves forward in the state in which the arms 330 provided on the tubular operation body 300 are connected to the ball valve 400 in the state in which the arms 330 is moved forward.

[0168] The arms 330 moves upward or downward while moving forward or rearward to turn the eccentric pins 420.

[0169] Meanwhile, a plurality of O-rings may be installed at the periphery of the rotary components to prevent the nib 111 from being dried or prevent volatile contents from being evaporated.

[0170] Further, the support ring 460 connected to the ball valve 400 is consistently pressed by the spring 460, and thus the ball valve 400 is in close contact with the ball seat 440, such that a gap is prevented from being formed at the periphery of the ball valve 400, thereby maintaining an effect of perfectly sealing the inside of the housing 100 for a long period of time.

[0171] According to the dual twist structure, the object ejecting device including the same, and the structure for sealing the same according to the present disclosure configured as described above, the content cartridge 110 may be applied to a writing instrument for storing volatile ink and preventing the ink from being dried, for example.

[0172] In addition, it is possible to prevent contents, such as stick cosmetics which may be discolored or degenerated, from being discolored or degenerated, and to maintain cleanliness for a long period of time.

[0173] A fixing unit 600 is provided on at least any one of an end of the cam groove 120 and an end of the twist cam groove 310.

[0174] According to the embodiment of the present disclosure, as illustrated in FIG. 21A, the fixing unit 600 may be provided at the end of the cam groove 120.

[0175] In this case, the fixing unit 600 includes a first stopper 610 formed to be convex toward the inside of the cam groove 120 and disposed on at least one of one end and two opposite ends of the cam groove 120.

[0176] The first stopper 610 is formed to be convex toward the inside of the cam groove 120, i.e., toward a centerline in the cam groove 120. When a predetermined pressure is further applied after the cam pin 320 approaches the first stopper 610, the cam pin 320 is resiliently fitted with and coupled to the first stopper 610.

[0177] In this case, the first stopper 610 may be convexly formed only at one side or two opposite sides toward the centerline in the cam groove 120. The cross-sectional shape of the first stopper 610 may be a streamlined shape or an angled shape.

[0178] That is, the fixing unit 600 restricts a movement of the cam pin 320 after the cam pin 320 moves along the cam groove 120 and is fitted with and coupled to the first stopper 610, such that it is possible to prevent the rotation of the operation cap 500 and allow the user to recognize the rotation of the operation cap 500 and easily check whether the object ejecting device is sealed.

[0179] In addition, as illustrated in FIG. 21B, the fixing unit 600 may be provided at the end of the twist cam groove 310.

[0180] In this case, the fixing unit 600 includes a second stopper 620 formed to be convex toward the inside of the twist cam groove 310 and disposed on at least one of one end and two opposite ends of the twist cam groove 310.

[0181] The second stopper 620 is formed to be convex toward the inside of the twist cam groove 310, i.e., toward a centerline in the twist cam groove 310. When a predetermined pressure is further applied after the cam protrusion 210 approaches the second stopper 620, the cam protrusion 210 is resiliently fitted with and coupled to the second stopper 620.

[0182] In this case, the second stopper 620 may be convexly formed only at one side or two opposite sides toward the centerline in the twist cam groove 310. The cross-sectional shape of the second stopper 620 may be a streamlined shape or an angled shape.

[0183] That is, the fixing unit 600 restricts a movement of the cam protrusion 210 after the cam protrusion 210 moves along the twist cam groove 310 and is fitted with and coupled to the second stopper 620, such that it is possible to prevent the rotation of the operation cap 500 and allow the user to recognize the rotation of the operation cap 500 and easily check whether the object ejecting device is sealed.

[0184] According to still another embodiment of the present disclosure, as illustrated in FIG. 22A, the fixing unit 600 may be provided at the end of the cam groove 120.

[0185] In this case, the fixing unit 600 includes a first magnet 630 disposed on at least one of one end and two opposite ends of the cam groove 120.

[0186] The first magnet 630 may be attached to or embedded in at least one of one end and two opposite ends of the cam groove 120. The first magnet 630 is made of a material for providing a magnetic force, such that when the cam pin 320 approaches the first magnet 630, the cam pin 320 is coupled to the first magnet 630 by the magnetic force.

[0187] That is, the fixing unit 600 may restrict the movement of the cam pin 320 by means of the magnetic force of the first magnet 630 when the cam pin 320 moves along the cam groove 120. Therefore, it is possible to prevent the rotation of the operation cap 500 and allow the user to recognize the rotation of the operation cap 500 and easily check whether the object ejecting device is sealed.

[0188] In addition, as illustrated in FIG. 22B, the fixing unit 600 may be provided at the end of the twist cam groove 310.
