[0017] In order to fully understand the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiment of the present invention may be changed in various forms, and the scope of the present invention must not be interpreted as being limited to the following embodiment described below in detail. The present embodiment is provided to more completely describe the present invention to a person having ordinary skill in the art to which the present invention pertains. Consequently, the shapes, etc. of elements in the drawings may be exaggerated for clearer description. It should be noted that identical members may be denoted by the same reference numerals in the drawings. A detailed description of related known functions and constructions will be omitted when the same may obscure the subject matter of the present invention.
[0018] FIG. 1 is a perspective view showing a dyeing agent discharge state of a dyeing device 100 according to the present invention, FIG. 2 is a perspective view showing a storage state of the dyeing device 100, FIG. 3 is an exploded perspective view showing the configuration of the dyeing device 100, and FIG. 4 is a sectional view showing the dyeing agent discharge state of the dyeing device 100.
[0019] As shown, the dyeing device 100 according to the present invention includes a cartridge 110 to which a pair of cylinders 111 and 113 configured respectively to accommodate a dyeing agent A and an oxidizing agent B is coupled, a sealing socket 120 and an socket outer cap 130 coupled to a tip end of the cartridge 110 to prevent discharge of the dyeing agent A and the oxidizing agent B to the outside when the dyeing agent A and the oxidizing agent B are stored, a mixing tip outer case 140 and a mixing member 150 coupled to the tip end of the cartridge 110 to mix and discharge the dyeing agent A and the oxidizing agent B after the sealing socket 120 and the socket outer cap 130 are removed when the dyeing agent A and the oxidizing agent B need to be mixed and discharged to the outside, and a pair of plungers 160 coupled respectively to the rear of the pair of cylinders 111 and 113, the pair of plungers being configured to move forward while being pressed by external force and to discharge the dyeing agent A and the oxidizing agent B in the pair of cylinders 111 and 113 to the outside.
[0020] In the dyeing device 100 according to the present invention, in a storage state in which the dyeing agent and the oxidizing agent are not used, as shown in FIG. 2, the sealing socket 120 and the socket outer cap 130 are coupled to the cartridge 110 such that the dyeing agent and the oxidizing agent are stored so as not to be discharged.
[0021] On the other hand, when the dyeing agent and the oxidizing agent need to be discharged for dyeing, as shown in FIG. 1, the sealing socket 120 and the socket outer cap 130 are coupled to the cartridge 110, and a dyeing mixture A+B, in which the dyeing agent A and the oxidizing agent B are uniformly mixed with each other, is discharged to the outside. Consequently, it is possible to eliminate inconvenience of a user having to manually squeeze the dyeing agent A and the oxidizing agent B into a container and mix the dyeing agent and the oxidizing agent and for even an unskilled person to uniformly mix the dyeing agent and the oxidizing agent.
[0022] Furthermore, in the dyeing device 100 according to the present invention, a residual pressure removal ring 165 is coupled to the plunger 160, wherein, when a user move the plunger 160 to discharge the required amount of dyeing agent and releases the pressing force, the plunger 160 retracts due to elastic force, thereby eliminating residual pressure. As a result, it is possible to discharge only the precise amount of dyeing agent and oxidizing agent to the outside without leakage of the dyeing agent and the oxidizing agent due to residual pressure.
[0023] The dyeing agent A and the oxidizing agent B are independently stored in the cartridge 110, and the dyeing agent A and the oxidizing agent B are discharged by pressing of the pair of plungers 160. The cartridge 110 includes a dyeing agent cylinder 111 configured to accommodate the dyeing agent A and an oxidizing agent cylinder 113 configured to accommodate the oxidizing agent B, wherein the dyeing agent cylinder 111 and the oxidizing agent cylinder 113 are coupled to each other in the state in which the dyeing agent cylinder and the oxidizing agent cylinder are disposed side by side.
[0024] The dyeing agent cylinder 111 and the oxidizing agent cylinder 113 are attached to each other so as to be integrally fixed to each other on one side of each other, and are coupled to each other via a lower flange 117 at lower parts thereof. A dyeing agent discharge tube 111a configured to discharge the dyeing agent A is formed at the front of the dyeing agent cylinder 111, and an oxidizing agent discharge tube 113a configured to discharge the oxidizing agent B is formed at the front of the oxidizing agent cylinder 113.
[0025] A pair of cap fixing wings 115, to which the socket outer cap 130 and the mixing tip outer case 140 are detachably fixed, is provided so as to face each other in front of the dyeing agent cylinder 111 and oxidizing agent cylinder 113, at which the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a are formed, respectively. The cap fixing wing 115 is provided with a "¬"-shaped cap fixing protrusion 115a, in which cartridge coupling ribs 135 and 142 of the socket outer cap 130 and the mixing tip outer case 140 are supported so as to be coupled while moving.
[0026] The lower flange 117 integrally connects the lower parts of the dyeing agent cylinder 111 and the oxidizing agent cylinder 113 to each other. The lower flange 117 extends horizontally outward from the lower parts of the dyeing agent cylinder 111 and the oxidizing agent cylinder 113 in a radial direction over a certain area.
[0027] The sealing socket 120 and the socket outer cap 130 are used to store the dyeing agent A and the oxidizing agent B such that the dyeing agent and the oxidizing agent cannot be discharged to the outside, as shown in FIG. 2. As shown in FIG. 3, the sealing socket 120 blocks and seals the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a. The socket outer cap 130 is fixed to the outside of the sealing socket 120 such that the user rotates the socket outer cap while holding the same by hand to remove the sealing socket 120 from the cartridge 110.
[0028] The sealing socket 120 includes a disc-shaped socket body 121 press-fit into and fixed to the socket outer cap 130, a first discharge tube stopper 123 and a second discharge tube stopper 125 provided at the rear of the socket body 121 such that the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a are inserted into the first discharge tube stopper and the second discharge tube stopper, respectively, and a dyeing tip support rib 127 protruding forward from the socket body 121.
[0029] The first discharge tube stopper 123 and the second discharge tube stopper 125 are inserted respectively into the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a to seal the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a.
[0030] The dyeing tip support rib 127 protrudes forward from the socket body 121 by a certain length. A dyeing agent color indication tip 128 is coupled to a tip end of the protruding dyeing tip support rib 127 to externally indicate the color of the dyeing agent A.
[0031] The dyeing agent color indication tip 128 is configured to have the color of the dyeing agent A accommodated in the dyeing agent cylinder 111. As shown in the enlarged view of FIG. 2, the dyeing agent color indication tip 128 is accommodated in a tip exposure hole 133a of the socket outer cap 130 during storage and externally indicates the color of the dyeing agent A accommodated in the dyeing agent cylinder 111.
[0032] The socket outer cap 130 is coupled to the tip end of the cartridge 110 with the sealing socket 120 accommodated therein. The socket outer cap 130 includes a socket outer cap body 131 into which the sealing socket 120 is press-fitted so as to be fixed thereto and an outer cap handle 133 protruding from a tip end of the socket outer cap body 131 to accommodate the dyeing tip support rib 127.
[0033] The socket outer cap body 131 is wedged between the pair of cap fixing wings 115 of the cartridge 110 so as to be fixed in position, as shown in FIG. 2. A pair of first cartridge coupling ribs 135 inserted into the cap fixing wings 115 while rotating in a circumferential direction is provided on an outer circumferential surface of a lower end of the socket outer cap body 131.
[0034] The first cartridge coupling rib 135 is formed lower than the height of the cap fixing wing 115, allowing the socket outer cap body 131 to rotate 90 degrees through the interior of the cap fixing wing 115. A first additional rotation prevention rib 135a located higher than the cap fixing wing 115 is provided at an end of the first cartridge coupling rib 135 so as to be supported by the cap fixing wings 115 in contact therewith.
[0035] The first additional rotation prevention rib 135a prevents further rotation of the socket outer cap 130 by an angle of 90 degrees of more while being supported by the cap fixing wings 115 in contact therewith.
[0036] The outer cap handle 133 protrudes on both sides, allowing the user to rotate the socket outer cap body 131 clockwise or counterclockwise while holding the outer cap handle 133 such that the socket outer cap body can be fixed to or separated from the cartridge 110 together with the sealing socket 120.
[0037] The mixing tip outer case 140 and the mixing member 150 are coupled to the tip end of the cartridge 110, as shown in FIG. 1, when the dyeing mixture A+B, in which the dyeing agent A and the oxidizing agent B are mixed with each other, needs to be discharged to the outside for hair dyeing. At this time, the user removes the socket outer cap 130 and the sealing socket 120 from the cartridge 110, and couples the mixing member 150 and the mixing tip outer case 140 to the cartridge 110.
[0038] The mixing tip outer case 140 is coupled to the cartridge 110 and guides the dyeing agent A and the oxidizing agent B, supplied independently from the cartridge 110, to be mixed with each other and be supplied to a dyeing container or a dyeing area. The mixing tip outer case 140 includes a tip body 141 coupled to the cartridge 110, a mixing member accommodation tube 143 configured to accommodate the mixing member 150 therein and to guide the dyeing mixture A+B, and a tip color code handle 145 coupled to the mixing member accommodation tube 143 and the tip body 141 therebetween to fix the position of the tip body 141.
[0039] The tip body 141 has a cylindrical shape with an open lower part, and is coupled to a front surface of the cartridge 110. The tip body 141 accommodates a mixing socket 151 of the mixing member 150 therein and guides the dyeing agent A and the oxidizing agent B discharged through the mixing socket 151 to be introduced into the mixing member accommodation tube 143 and to be mixed by the mixing member 150.
[0040] A second cartridge coupling rib 142 and a second additional rotation prevention rib 142a coupled to the cap fixing wings 115 of the cartridge 110 therebetween are provided on an outer circumferential surface of the tip body 141. The configuration of the second cartridge coupling rib 142 and the second additional rotation prevention rib 142a is identical to that of the first cartridge coupling rib 135 and the first additional rotation prevention rib 135a of the socket outer cap 130 described above.
[0041] The mixing member accommodation tube 143 accommodates the mixing member 150 and provides a space in which the dyeing agent A and the oxidizing agent B can be mixed with each other. The mixing member accommodation tube 143 has an inner diameter corresponding to the diameter of the mixing element 155 of the mixing member 150, as shown in FIG. 7, thereby forming an internal space that prevents the dyeing agent A and the oxidizing agent B from moving forward without passing through the mixing element 155. A mixture discharge hole 143a configured to discharge the dyeing mixture A+B is formed at the end of the mixing member accommodation tube 143, whereby the dyeing mixture A+B, in which the dyeing agent A and the oxidizing agent B are mixed with each other, is discharged to the outside.
[0042] The tip color code handle 145 is provided at a boundary area between the tip body 141 and the mixing member accommodation tube 143. As shown in FIG. 3, a pair of handle fixing ribs 141b is provided on a front surface of the tip body 141 so as to protrude from both sides of the mixing member accommodation tube 143.
[0043] The pair of handle fixing ribs 141b is accommodated in the tip color code handle 145, as shown in FIG. 1. The tip color code handle 145 is configured to have the same color as the dyeing agent A accommodated in the dyeing agent cylinder 111, enabling the user to recognize the color of the dyeing agent A currently in use.
[0044] In addition, the tip color code handle 145 is formed in the shape of a handle with a certain area on both sides, allowing the user to rotate the mixing tip outer case 140 clockwise or counterclockwise so as to be coupled to or separated from the cartridge 110 while holding the tip color code handle.
[0045] The mixing member 150 is provided in the mixing tip outer case 140 to mix the dyeing agent A and the oxidizing agent B independently discharged from the cartridge 110 with each other. The mixing member 150 includes a mixing socket 151 accommodated in the tip body 141, a dyeing agent movement tube 152 and an oxidizing agent movement tube 153 provided at the rear of the mixing socket 151 and connected to the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a, respectively, and a mixing element 155 formed at the front of the mixing socket 151 so as to protrude therefrom by a certain length, the mixing element being accommodated in the mixing member accommodation tube 143, the mixing element being configured to mix the dyeing agent A and the oxidizing agent B discharged through the mixing socket 151 with each other.
[0046] The mixing socket 151 is press-fitted into and fixed to the tip body 141, as shown in FIG. 7. An outer wall surface of the mixing socket 151 is press-fitted into an inner wall surface of the tip body 141. An outer coupling rib 151a formed on the outer wall surface of the mixing socket 151 is press-fitted into an inner detachment prevention rib 141a formed on the inner wall surface of the tip body 141, whereby integral coupling therebetween is achieved. When the tip body 141 is attached to or detached from the cartridge 110, the tip body is attached to or detached from the cartridge in a state of being coupled to the mixing socket 151.
[0047] The dyeing agent movement tube 152 and the oxidizing agent movement tube 153 are connected to the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a of the cartridge 110, respectively. A dyeing agent supply hole 152a communicating with the dyeing agent movement tube 152 and an oxidizing agent supply hole 153a communicating with the oxidizing agent movement tube 153 are formed in a front surface of the mixing socket 151.
[0048] The dyeing agent A and the oxidizing agent B discharged respectively through the dyeing agent supply hole 152a and the oxidizing agent supply hole 153a move to the mixing member accommodation tube 143 and pass through the mixing element 155 disposed in the mixing member accommodation tube 143.
[0049] The mixing element 155 allows the dyeing agent A and the oxidizing agent B, supplied through the dyeing agent supply hole 152a and the oxidizing agent supply hole 153a, to move therethrough while being mixed with each other. The mixing element 155 has a screw blade helically formed in a longitudinal direction. The dyeing agent A and the oxidizing agent B are mixed with each other while moving through the space between the mixing element 155 and the mixing member accommodation tube 143 due to discharge pressure, and are discharged outside the mixing member accommodation tube 143.
[0050] The plunger 160 is inserted into rear ends of the dyeing agent cylinder 111 and the oxidizing agent cylinder 113 of the cartridge 110, and pressurizes the dyeing agent A and the oxidizing agent B so as to be discharged to the dyeing agent discharge tube 111a and oxidizing agent discharge tube 113a while being moved forward along inner wall surfaces of the dyeing agent cylinder 111 and the oxidizing agent cylinder 113 by user pressing. The plunger 160 includes a pair of bar-shaped plunger bodies 161, a pair of front coupling members 163 coupled to the front of the pair of plunger bodies 161 to pressurize the dyeing agent A and the oxidizing agent B, and a residual pressure removal ring 165 coupled to the front coupling members 163 to remove residual pressure while elastically moving forward and backward in conjunction with forward and backward movement of the plunger 160 due to pressing.
[0051] As shown in FIGs. 3 and 4, the pair of plunger bodies 161 is inserted into rear ends of the dyeing agent discharge tube 111a and the oxidizing agent discharge tube 113a, respectively. A front coupling plate 161a configured to support the front coupling member 163 in contact therewith is provided at the front of the pair of plunger bodies 161. A pressing member coupling shaft 161c is formed on a central region of the front coupling plate 161a so as to protrude therefrom. As shown in FIG. 4, the pressing member coupling shaft 161c is inserted into the front coupling member 163 such that the front coupling member 163 is fixed to the plunger body 161.
[0052] A rear flange 161b is provided at the rear of the pair of plunger bodies 161. The rear flange 161b is provided in a pair so as to be integrally coupled to the plunger bodies 161 such that the user presses the rear flanges 161b to simultaneously move the pair of plunger bodies 161.
[0053] The front coupling member 163 moves while pressurizing the dyeing agent A and the oxidizing agent B during the forward movement of the plunger body 161. The front coupling member 163 includes a front pressing plate 163a, a rear support plate 163b provided so as to be spaced apart from the front pressing plate 163a, the rear support plate being configured to support the front coupling plate 161a in contact therewith, and a guide shaft 163c provided between the front pressing plate 163a and the rear support plate 163b to support the residual pressure removal ring 165.
[0054] The guide shaft 163c is configured such that the outer diameter thereof gradually increases from the front to the rear, as shown in the enlarged view of FIG. 3. The guide shaft 163c moves forward due to the pressure applied by the plunger body 161 and supports the residual pressure removal ring 165 coupled to an outer circumferential surface thereof so as to be elastically stretched while moving rearward.
[0055] FIG. 6(a) is a sectional view taken along line A-A of the enlarged view of FIG. 3, and FIG. 6(b) is a sectional view taken along line B-B of the enlarged view of FIG. 3.
[0056] Expansion wings 163d are provided on both sides of the guide shaft 163c. The expansion wings 163d are configured such that the width and thickness thereof gradually increase from the front to the rear of the guide shaft 163c. As shown in FIG. 6(a), the foremost sectional shape of the guide shaft 163c is a circular shape having an outer diameter corresponding to the inner diameter of the residual pressure removal ring 165. In this case, as shown in FIG. 5(a), the residual pressure removal ring 165 is coupled to the guide shaft 163c in an initial state without elastic deformation.
[0057] As shown in FIG. 6(b), the rear sectional shape of the guide shaft 163c is a shape with horns protruding from both sides due to the expansion wings 163d. The degree of elastic deformation of the residual pressure removal ring 165 coupled to an outer circumferential surface of the guide shaft 163c increases due to the shape of the expansion wings 163d, which gradually increase in width and thickness toward the rear of the guide shaft 163c. Consequently, as shown in FIG. 5(b), the shape of the residual pressure removal ring 165 is elastically deformed so as to correspond to the shape of the guide shaft 163c.
[0058] The residual pressure removal ring 165 is coupled to the guide shaft 163c of the pair of plunger bodies 161, is elastically deformed while moving forward and backward along the guide shaft 163c in conjunction with forward and backward movement of the plunger 160 due to pressing, and removes residual pressure in the dyeing agent cylinder 111 and the oxidizing agent cylinder 113 as the plunger body 161 moves rearward.
[0059] The residual pressure removal ring 165 is formed in an elastic ring shape, as shown in FIG. 3. The residual pressure removal ring 165 is formed in a ring shape having a thickness corresponding to the space between the front of the guide shaft 163c and the inner diameters of the dyeing agent cylinder 111 and the oxidizing agent cylinder 113 in an initial state, as shown in FIG. 5A.
[0060] As shown in FIG. 5(b) and FIG. 8(a), when the plunger body 161 is pressed by the user, the plunger body 161 moves forward along the inner diameters of the dyeing agent cylinder 111 and the oxidizing agent cylinder 113, and the dyeing agent A and the oxidizing agent B are discharged through the mixing tip outer case 140.
[0061] At this time, the residual pressure removal ring 165 is pushed rearwardly of the guide shaft 163c by movement pressure of the plunger body 161 and the friction force with the inner wall surfaces of the dyeing agent cylinder 111 and the oxidizing agent cylinder 113, and discharges the dyeing agent and the oxidizing agent while moving forward together with the plunger body 161 in contact with the forward pressing plate 163a.
[0062] If the width difference with the expansion wings 163d formed on both sides of the guide shaft 163c is great when the residual pressure removal ring 165 moves rearward, the rearward movement amount of both side regions of the residual pressure removal ring 165 surrounding the expansion wings 163d is not great, and only the residual pressure removal ring 165 in the region where the expansion wings 163d are not formed is pushed rearward. That is, the rearward movement of the remaining region of the residual pressure removal ring 165 is greater than the rearward movement of the region of the residual pressure removal ring 165 surrounding the expansion wings 163d, thereby further increasing the deformation amount of the residual pressure removal ring 165.
[0063] Accordingly, as shown in FIG. 5(b), the residual pressure removal ring 165 remains wedged between the guide shaft 163c, the dyeing agent cylinder 111, and the oxidizing agent cylinder 113 in a state of being stretched, reduced in thickness, and elastically deformed in a wavy shape.
[0064] In this state, the residual pressure removal ring 165 moves forward together with the plunger body 161, and support the dyeing agent A and the oxidizing agent B so as to be discharged.
[0065] Upon completing pressing of the plunger body 161 to the position at which the desired amount of dyeing agent A and the oxidizing agent B is discharged, the user stops pressing the pair of plunger bodies 161 via the rear flange 161b. Upon releasing the user pressing of the plunger body 161, the residual pressure removal ring 165, elastically stretched and deformed at the rear end of the guide shaft 163c, applies elastic force toward the guide shaft 163c so as to move forwardly of the guide shaft 163c such that the residual pressure removal ring is compressed to the initial inner diameter thereof.
[0066] As a result, as shown in FIGs. 8(a) and 8(b), the plunger body 161 moves rearward due to the elastic force of the residual pressure removal ring 165, and the residual pressure removal ring 165 is located in front of the guide shaft 163c.
[0067] As the plunger 160 moves rearward by the length of the guide shaft 163c due to the elastic force of the residual pressure removal ring 165, as described above, the residual pressure applied to the plunger 160 is removed, whereby additional discharge of the liquid through the mixing tip outer case 140 is prevented and only the precise amount of dyeing mixture A+B is discharged.
[0068] Here, as the thickness and width of the expansion wing 163d of the guide shaft 163c increase, the degree of elastic deformation of the residual pressure removal ring 165 also increases, thereby improving the residual pressure removal effect.
[0069] In the dyeing device 100 according to the preferred embodiment of the present invention, the pair of expansion wings is provided on both sides of the guide shaft. In some cases, however, three or more expansion wings may be provided along the outer circumferential circumference of the guide shaft.
[0070] The operation of the dyeing device 100 according to the present invention having the above configuration will be described with reference to FIGs. 1 to 8.
[0071] When the dyeing device 100 is stored, the sealing socket 120 and the socket outer cap 130 are coupled to the front of the cartridge 110, as shown in FIG. 2. The dyeing device 100 having the sealing socket 120 and the socket outer cap 130 coupled thereto is packaged together with the mixing tip outer case 140 and the mixing member 150.
[0072] When it is necessary to discharge the dyeing agent A and the oxidizing agent B for hair dyeing, the user separates the socket outer cap 130, in which the sealing socket 120 is accommodated, from the cartridge 110, and couples the mixing tip outer case 140, in which the mixing member 150 is coupled, to the cartridge.
[0073] When the user presses the rear flange 161b located at the rear of the plunger 160, the pair of plunger bodies 161 moves forward, and the front coupling member 163 pressurizes the dyeing agent A and the oxidizing agent B. As shown in FIG. 7, the dyeing agent A moves from the dyeing agent cylinder 111 to the dyeing agent discharge tube 111a, and moves to the mixing member accommodation tube 143 via the dyeing agent movement tube 152 and the dyeing agent supply hole 152a of the mixing socket 151.
[0074] The oxidizing agent B moves from the oxidizing agent cylinder 113 through the oxidizing agent discharge tube 113a, and moves to the mixing member accommodation tube 143 via the oxidizing agent movement tube 153 and the oxidizing agent supply hole 153a of the mixing socket 151.
[0075] The dyeing agent A and the oxidizing agent B moved to the mixing member accommodation tube 143 are mixed with each other while moving along the mixing element 155. The dyeing agent A and the oxidizing agent B are uniformly mixed with each other while moving up to the tip end of the mixing member accommodation tube 143, and the dyeing mixture A+B is discharged to the outside through the mixture discharge hole 143a for dyeing.
[0076] Meanwhile, when the user presses the plunger 160, the residual pressure removal ring 165 coupled to the guide shaft 163c is elastically deformed while moving rearward, as shown in FIG. 8(a). When the desired amount of dyeing mixture A+B is discharged, pressing of the plunger 160 is stopped. When pressing of the plunger 160 is stopped, elastic force is applied to the elastically deformed residual pressure removal ring 165 such that residual pressure removal ring can be restored to the initial state thereof, and residual pressure is removed as the plunger 160 moves rearward, as shown in FIG. 8(b), whereby only the measured amount of the dyeing mixture A+B is discharged without further discharge thereof.
[0077] Meanwhile, when discharging of the desired amount of the dyeing mixture A+B is completed, the mixing tip outer case 140 and the mixing member 150 may be separated from the cartridge 110, and the sealing socket 120 and the socket outer cap 130 may be coupled to the cartridge again for storage.
[0078] As described above, in the dyeing agent cartridge assembly according to the present invention, the dyeing agent and the oxidizing agent are separately stored in the cartridge, and are discharged to the outside in a state of being uniformly mixed with each other using the mixing tip outer case and the mixing member for use.
[0079] Accordingly, it is possible to omit a conventional process of a user manually squeezing the dyeing agent and the oxidizing agent into a container and mixing the dyeing agent and the oxidizing agent with each other using a brush.
[0080] In particular, the present invention has the advantage that it is possible to precisely discharge only the desired amount of dyeing mixture by removing internal residual pressure using the residual pressure removal ring.
[0081] The embodiment of the dyeing device according to the present invention described above is exemplary only, and a person having ordinary skill in the art to which the present invention pertains will recognize that various modifications and other equivalent embodiments are possible therefrom. It will therefore be well understood that the present invention is not limited to the form recited in the above detailed description. Consequently, the true scope of technical protection of the present invention is to be determined by the technical ideas of the appended claims. In addition, the present invention is to be understood to include all variations, equivalents, and substitutes within the spirit and scope of the present invention as defined by the appended claims.[Description of Reference Symbols]
