[0024] In the present specification, the same reference numerals are assigned to the same components across different drawings wherever possible, even if they appear in different drawings. Singular expressions in the specification may include plural meanings unless otherwise specifically stated in the context. The terms "comprises" and "comprising" used in the present specification do not exclude the presence or addition of one or more other components apart from the listed components.

[0025] The above and other objectives, features, and advantages of the present invention will become more apparent from the following preferred embodiments with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in various other forms. Rather, the embodiments are provided to fully disclose the present invention and to allow those skilled in the art to fully understand the spirit of the present invention.

[0026] Hereinafter, preferred embodiments devised to solve the above-mentioned problems will be described in detail with reference to the accompanying drawings.

[0027] FIG. 1 is an exploded perspective view illustrating a configuration of a paste dispensing control device according to an embodiment of the present invention.

[0028] Referring to FIG. 1, the paste dispensing control device according to an embodiment of the present invention may include a device body 1100, a slide plate 1200, a filter unit 1300, and a container 1400.

[0029] The container 1400 may be configured to contain a paste-type composition.

[0030] The paste-type composition may be a fluid with viscosity. In one embodiment, the paste-type composition may include any one of an aqueous solution, an emulsion, and oil. In another embodiment, the paste-type composition may include any one of gel, cream, wax, and mousse.

[0031] According to one embodiment, the container 1400 may be a flexible container such as a tube. The flexible container is easily deformable by external pressure and may discharge the composition contained therein by pressure. The flexible container may be a tube made of rubber, plastic, or metal.

[0032] According to another embodiment, the container 1400 may be a rigid container such as a bottle. The rigid container has a fixed shape and rigidity, and thus, may discharge the composition contained therein using a pump or an automatic discharge device. The rigid container may be a bottle made of plastic or metal.

[0033] The container 1400 may include a discharge port through which the contained composition is discharged. The discharge port may be provided with a thread capable of being coupled to the device body 1100.

[0034] The discharge port of the container 1400 may vary in size depending on the container.

[0035] One side of the filter unit 1300 may be threadably coupled to the discharge port of the container 1400. The discharge port of the container 1400 may be inserted into and coupled to the filter unit.

[0036] The other side of the filter unit 1300 may be threadably coupled to the device body 1100. The filter unit 1300 may be inserted into and coupled to the device body 1100.

[0037] The container 1400 and the device body 1100 may be coupled without the filter unit 1300. A user may selectively decide whether to couple the container 1400 and the device body 1100 including the filter unit 1300 or not.

[0038] The device body 1100 may be coupled to the filter unit 1300 or the container 1400. The composition discharged from the container 1400 may be discharged through a discharge outlet 1130 formed in the device body.

[0039] The slide plate 1200 may be coupled to the device body 1100 and may be slidable in the vertical direction. Depending on the slid position, the slide plate 1200 may open or close the discharge outlet 1130 to control the discharge of the composition.

[0040] FIG. 2 is a perspective view illustrating the filter unit according to an embodiment of the present invention.

[0041] FIG. 3 is a bottom plan view illustrating a state in which the device body and the filter unit are coupled according to an embodiment of the present invention.

[0042] Referring to FIGS. 2 and 3, the filter unit 1300 according to an embodiment of the present invention may include a mesh-type filter 1310 provided inside a cylindrical space connected to a flow path 1120.

[0043] Even if a sudden high pressure is applied inside the container 1400, the mesh-type filter 1310 may allow the composition to be discharged at a consistent rate. The pressure resistance of the mesh-type filter 1310 may vary depending on the mesh size. As the mesh size is smaller, the composition can be consistently discharged even under high pressure.

[0044] The mesh-type filter 1310 may make the particles of the composition contained in the container 1400 uniform. The composition contained in the container may coagulate and form lumps inside the container. The coagulated composition lumps may hinder the movement of the composition and interrupt the composition from being discharged uniformly. The coagulated composition lumps may be crushed into smaller particles while passing through the mesh-type filter 1310.

[0045] The filter unit 1300 may include an upper filter portion 1320 coupled to a coupling part 1110 of the device body 1100 and a lower filter portion 1330 coupled to the discharge port of the container 1400.

[0046] The upper filter portion 1320 may be cylindrical and have an outer diameter equal to the inner diameter of the coupling part 1110 so as to be coupled to the coupling part 1110 of the device body 1100. The upper filter portion 1320 may have a thread capable of being coupled to a thread 1111 of the coupling part 1110.

[0047] The lower filter portion 1330 may also be cylindrical, and the discharge port of the container 1400 may be coupled by being inserted into the lower filter portion 1330. A thread may be formed on the inner circumferential surface of the lower filter portion 1330 to be coupled to the discharge port of the container 1400.

[0048] The lower filter portion 1330 may vary in size depending on the size of the discharge port of the container 1400. Therefore, a plurality of filter units 1300 having the lower filter portions 1330 of different sizes may be provided. The user may select the filter unit 1300 with the lower filter portion 1330 that matches the size of the discharge port of the container 1400.

[0049] A mesh material of the mesh-type filter 1310 may be fiber or metal.

[0050] FIG. 4 is a cross-sectional view illustrating the device body according to an embodiment of the present invention.

[0051] FIG. 5 is a perspective view illustrating the device body according to an embodiment of the present invention.

[0052] Referring to FIGS. 4 and 5, a device body 1100 according to an embodiment of the present invention may include the coupling part 1110, the flow path 1120, and the discharge outlet 1130.

[0053] The coupling part 1110 may be formed in a cylindrical shape at a lower portion of the device body 1100. The coupling part 1110 may be threadably coupled to the discharge port of the container 1400 or to the filter unit 1300.

[0054] The thread 1111 may be formed on the inner circumferential surface of the cylindrical coupling part 1110.

[0055] The flow path 1120 through which the composition may move may be formed inside the device body 1100. One end of the flow path 1120 may be connected to the coupling part 1110, and the other end may be connected to the discharge outlet 1130.

[0056] The flow path 1120 may be formed to incline in the direction of the discharge port of the container 1400 to allow the composition to flow smoothly.

[0057] The discharge outlet 1130 may be formed in an elongated slit shape extending in the lateral direction. The composition that has passed through the flow path 1120 may be discharged through the slit-shaped discharge outlet 1130 and may be applied to the skin in a wide lateral spread with a thin thickness.

[0058] The discharge outlet 1130 may include one or more slits spaced at regular intervals in the vertical direction. The composition passing through the flow path 1120 may be discharged through the long and narrow slit-shaped discharge outlet, thereby being applied to the skin evenly and widely.

[0059] In one embodiment, one or more discharge outlets 1130 may be provided. For example, there may be one discharge outlet or five discharge outlets. When the plurality of discharge outlets 1130 are formed, the amount of composition discharged may increase as the number of opened discharge outlets 1130 increases.

[0060] In an embodiment of the present invention, rather than adopting a method of increasing the width of the discharge outlet to increase the amount of discharged composition, a method of increasing the number of slit-shaped discharge outlets 1130 is adopted. Increasing the number of slit-shaped discharge outlets 1130 may be more advantageous in maintaining a consistent discharge amount than increasing the width of the outlet.

[0061] In general, pressure is applied to the inside of the container to discharge the composition contained therein. However, due to the viscosity of the composition and the strength of the pressure, it is difficult to consistently maintain the discharge amount of the composition. In particular, as the size of the discharge outlet increases, the amount of discharged composition also increases, making it even more difficult to maintain the constant discharge amount.

[0062] However, in an embodiment of the present invention, the amount of discharge is adjusted by increasing the number of open discharge outlets 1130 while keeping the width of each discharge outlet 1130 constant, thereby making it easier to maintain a consistent discharge amount.

[0063] In one embodiment, the slit width of the discharge outlet 1130 may gradually increase from an upper outlet to a lower outlet. For example, when there are five discharge outlets 1130, the slit width of the topmost discharge outlet may be formed as 1 mm, and the slit width may increase by 0.5 mm for each outlet going downward. According to one embodiment, the discharge amount of the composition is exponentially increased as the number of opened discharge outlets 1130 increases.

[0064] In another embodiment, the slit widths of the discharge outlets 1130 may all be the same. For example, five discharge outlets 1130 may each have the same slit width of 1 mm. In one embodiment, the discharge amount increases uniformly in proportion to the number of opened discharge outlets 1130.

[0065] The device body 1100 according to an embodiment of the present invention may include recessed grooves 1140 formed longitudinally on both sides of the discharge outlet 1130 to allow the slide plate 1200 to be in contact with the discharge outlet 1130 and to guide the vertical movement of the slide plate 1200.

[0066] The recessed groove 1140 may have a concave (-shaped) cross-section. The recessed groove 1140 may be formed to match the thickness and height of the slide plate 1200 so that the slide plate 1200 can be inserted.

[0067] Portions of the left and right sides of the slide plate 1200 may be inserted into the recessed grooves 1140 to be vertically movable. The slide plate 1200 may move only in the longitudinal direction along the recessed grooves 1140.

[0068] The width of the recessed grooves 1140 may be formed to match the thickness of the slide plate 1200, so that the slide plate 1200 can be in contact with the discharge outlet 1130.

[0069] The device body 1100 may further include a plurality of rear locking grooves 1150, which are arranged in a row on right and left sides of the discharge outlet 1130, and to which rear locking protrusions 1220 to fix the slide plate 1200 moved vertically are coupled.

[0070] The rear locking grooves 1150 may be formed to correspond to positions in which the slide plate 1200 opens or closes each of the discharge outlets 1130.

[0071] In one embodiment, when the slide plate 1200 closes all the discharge outlets 1130, all of the rear locking grooves 1150 may be coupled to the rear locking protrusions of the slide plate 1200. When the slide plate 1200 is positioned to open only some of the discharge outlets 1130, the rear locking grooves 1150 may be coupled to a portion of the rear locking protrusions of the slide plate 1200.

[0072] The device body 1100 may further include a plurality of front locking grooves 1160, which are arranged in a row on the inner surfaces of the recessed grooves 1140, and to which the front locking protrusions 1210 to fix the slide plate 1200 moved vertically are coupled.

[0073] The front locking grooves 1160 may be formed to correspond to positions in which the slide plate 1200 opens or closes each of the discharge outlets 1130. The front locking grooves 1160 may be formed on surfaces facing the rear locking grooves 1150. The front locking grooves 1160 may be vertically offset from the rear locking grooves 1150.

[0074] The front and rear locking grooves 1160 and 1150 may be formed in a hemispherical or other concave shape to match the shape of the front and rear locking protrusions 1210 and 1220.

[0075] FIG. 6 is a perspective view illustrating a state in which the device body and the slide plate are coupled according to an embodiment of the present invention.

[0076] Referring to FIG. 6, the slide plate 1200 according to one embodiment of the present invention may be inserted into the device body 1100 and vertically slidable.

[0077] The slide plate 1200 may sequentially open or close the slit-shaped discharge outlets 1130 while moving vertically along the recessed grooves 1140.

[0078] The front and rear locking protrusions 1210 and 1220 formed on the front and rear surfaces of the slide plate 1200 may be respectively coupled to the front and rear locking grooves 1160 and 1150 formed in the device body 1100, thereby fixing the slide plate 1200 in position.

[0079] FIG. 7 is a side view illustrating the slide plate according to an embodiment of the present invention.

[0080] FIG. 8 is a front view and a rear view illustrating the slide plate according to an embodiment of the present invention.

[0081] Referring to FIGS. 7 and 8, the slide plate 1200 according to an embodiment of the present invention may be a T-shaped plate having a predetermined thickness. The slide plate 1200 may have a lateral length formed to match the spacing between the left and right recessed grooves 1140 to be inserted into the recessed grooves 1140.

[0082] The slide plate 1200 may include a handle 1230 that allows a user to grip and operate the slide plate 1200. In one embodiment, the side of the slide plate 1200 having the handle 1230 may be L-shaped.

[0083] A plurality of front locking protrusions 1210 may be formed in a row on the left and right sides of the slide plate 1200 to fix the position of the slide plate 1200 after the vertical movement. As described above, the front locking protrusions 1210 may be coupled to the front locking grooves 1160 of the device body 1100 to fix the position of the slide plate 1200.

[0084] A plurality of rear locking protrusions 1220 may also be formed in a row on the left and right sides of the slide plate 1200 to fix the position of the slide plate 1200 after the vertical movement. The rear locking protrusions 1220 may be coupled to the rear locking grooves 1150 of the device body 1100 to fix the position of the slide plate 1200.

[0085] The slide plate 1200 according to an embodiment of the present invention may further include a lubrication pad 1240 provided on the front surface thereof to reduce friction with the skin. The lubrication pad 1240 may be a rectangular pad having a predetermined thickness.

[0086] The lubrication pad 1240 may be made of materials such as silicone, polymer, or Teflon. The lubrication pad 1240 may contain ingredients, which soothe the skin and provide moisturizing effects, such as vitamins, oils, or shea butter.

[0087] Although the embodiments have been described above with reference to limited examples and drawings, it will be apparent to those skilled in the art that various modifications and variations may be made without departing from the scope of the present invention. For example, the described technologies may be carried out in different sequences from those described, and / or the components of the described structures or devices may be coupled or combined with different forms, or substituted or rearranged with other components or equivalents to achieve desired results.

Singular expressions in the specification may include plural meanings unless otherwise specifically stated in the context. The terms "comprises" and "comprising" used in the present specification do not exclude the presence or addition of one or more other components apart from the listed components.

[0025] The above and other objectives, features, and advantages of the present invention will become more apparent from the following preferred embodiments with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in various other forms. Rather, the embodiments are provided to fully disclose the present invention and to allow those skilled in the art to fully understand the spirit of the present invention.

[0026] Hereinafter, preferred embodiments devised to solve the above-mentioned problems will be described in detail with reference to the accompanying drawings.

[0027] FIG. 1 is an exploded perspective view illustrating a configuration of a paste dispensing control device according to an embodiment of the present invention.

[0028] Referring to FIG. 1, the paste dispensing control device according to an embodiment of the present invention may include a device body 1100, a slide plate 1200, a filter unit 1300, and a container 1400.

[0029] The container 1400 may be configured to contain a paste-type composition.

[0030] The paste-type composition may be a fluid with viscosity. In one embodiment, the paste-type composition may include any one of an aqueous solution, an emulsion, and oil. In another embodiment, the paste-type composition may include any one of gel, cream, wax, and mousse.

[0031] According to one embodiment, the container 1400 may be a flexible container such as a tube. The flexible container is easily deformable by external pressure and may discharge the composition contained therein by pressure. The flexible container may be a tube made of rubber, plastic, or metal.

[0032] According to another embodiment, the container 1400 may be a rigid container such as a bottle. The rigid container has a fixed shape and rigidity, and thus, may discharge the composition contained therein using a pump or an automatic discharge device. The rigid container may be a bottle made of plastic or metal.

[0033] The container 1400 may include a discharge port through which the contained composition is discharged. The discharge port may be provided with a thread capable of being coupled to the device body 1100.

[0034] The discharge port of the container 1400 may vary in size depending on the container.

[0035] One side of the filter unit 1300 may be threadably coupled to the discharge port of the container 1400. The discharge port of the container 1400 may be inserted into and coupled to the filter unit.

[0036] The other side of the filter unit 1300 may be threadably coupled to the device body 1100. The filter unit 1300 may be inserted into and coupled to the device body 1100.

[0037] The container 1400 and the device body 1100 may be coupled without the filter unit 1300. A user may selectively decide whether to couple the container 1400 and the device body 1100 including the filter unit 1300 or not.

[0038] The device body 1100 may be coupled to the filter unit 1300 or the container 1400. The composition discharged from the container 1400 may be discharged through a discharge outlet 1130 formed in the device body.

[0039] The slide plate 1200 may be coupled to the device body 1100 and may be slidable in the vertical direction. Depending on the slid position, the slide plate 1200 may open or close the discharge outlet 1130 to control the discharge of the composition.

[0040] FIG. 2 is a perspective view illustrating the filter unit according to an embodiment of the present invention.

[0041] FIG. 3 is a bottom plan view illustrating a state in which the device body and the filter unit are coupled according to an embodiment of the present invention.

[0042] Referring to FIGS. 2 and 3, the filter unit 1300 according to an embodiment of the present invention may include a mesh-type filter 1310 provided inside a cylindrical space connected to a flow path 1120.

[0043] Even if a sudden high pressure is applied inside the container 1400, the mesh-type filter 1310 may allow the composition to be discharged at a consistent rate. The pressure resistance of the mesh-type filter 1310 may vary depending on the mesh size. As the mesh size is smaller, the composition can be consistently discharged even under high pressure.

[0044] The mesh-type filter 1310 may make the particles of the composition contained in the container 1400 uniform. The composition contained in the container may coagulate and form lumps inside the container. The coagulated composition lumps may hinder the movement of the composition and interrupt the composition from being discharged uniformly. The coagulated composition lumps may be crushed into smaller particles while passing through the mesh-type filter 1310.

[0045] The filter unit 1300 may include an upper filter portion 1320 coupled to a coupling part 1110 of the device body 1100 and a lower filter portion 1330 coupled to the discharge port of the container 1400.

[0046] The upper filter portion 1320 may be cylindrical and have an outer diameter equal to the inner diameter of the coupling part 1110 so as to be coupled to the coupling part 1110 of the device body 1100. The upper filter portion 1320 may have a thread capable of being coupled to a thread 1111 of the coupling part 1110.

[0047] The lower filter portion 1330 may also be cylindrical, and the discharge port of the container 1400 may be coupled by being inserted into the lower filter portion 1330. A thread may be formed on the inner circumferential surface of the lower filter portion 1330 to be coupled to the discharge port of the container 1400.

[0048] The lower filter portion 1330 may vary in size depending on the size of the discharge port of the container 1400. Therefore, a plurality of filter units 1300 having the lower filter portions 1330 of different sizes may be provided. The user may select the filter unit 1300 with the lower filter portion 1330 that matches the size of the discharge port of the container 1400.

[0049] A mesh material of the mesh-type filter 1310 may be fiber or metal.

[0050] FIG. 4 is a cross-sectional view illustrating the device body according to an embodiment of the present invention.

[0051] FIG. 5 is a perspective view illustrating the device body according to an embodiment of the present invention.

[0052] Referring to FIGS. 4 and 5, a device body 1100 according to an embodiment of the present invention may include the coupling part 1110, the flow path 1120, and the discharge outlet 1130.

[0053] The coupling part 1110 may be formed in a cylindrical shape at a lower portion of the device body 1100. The coupling part 1110 may be threadably coupled to the discharge port of the container 1400 or to the filter unit 1300.

[0054] The thread 1111 may be formed on the inner circumferential surface of the cylindrical coupling part 1110.

[0055] The flow path 1120 through which the composition may move may be formed inside the device body 1100. One end of the flow path 1120 may be connected to the coupling part 1110, and the other end may be connected to the discharge outlet 1130.

[0056] The flow path 1120 may be formed to incline in the direction of the discharge port of the container 1400 to allow the composition to flow smoothly.

[0057] The discharge outlet 1130 may be formed in an elongated slit shape extending in the lateral direction. The composition that has passed through the flow path 1120 may be discharged through the slit-shaped discharge outlet 1130 and may be applied to the skin in a wide lateral spread with a thin thickness.

[0058] The discharge outlet 1130 may include one or more slits spaced at regular intervals in the vertical direction. The composition passing through the flow path 1120 may be discharged through the long and narrow slit-shaped discharge outlet, thereby being applied to the skin evenly and widely.

[0059] In one embodiment, one or more discharge outlets 1130 may be provided. For example, there may be one discharge outlet or five discharge outlets. When the plurality of discharge outlets 1130 are formed, the amount of composition discharged may increase as the number of opened discharge outlets 1130 increases.

[0060] In an embodiment of the present invention, rather than adopting a method of increasing the width of the discharge outlet to increase the amount of discharged composition, a method of increasing the number of slit-shaped discharge outlets 1130 is adopted. Increasing the number of slit-shaped discharge outlets 1130 may be more advantageous in maintaining a consistent discharge amount than increasing the width of the outlet.

[0061] In general, pressure is applied to the inside of the container to discharge the composition contained therein. However, due to the viscosity of the composition and the strength of the pressure, it is difficult to consistently maintain the discharge amount of the composition. In particular, as the size of the discharge outlet increases, the amount of discharged composition also increases, making it even more difficult to maintain the constant discharge amount.

[0062] However, in an embodiment of the present invention, the amount of discharge is adjusted by increasing the number of open discharge outlets 1130 while keeping the width of each discharge outlet 1130 constant, thereby making it easier to maintain a consistent discharge amount.

[0063] In one embodiment, the slit width of the discharge outlet 1130 may gradually increase from an upper outlet to a lower outlet. For example, when there are five discharge outlets 1130, the slit width of the topmost discharge outlet may be formed as 1 mm, and the slit width may increase by 0.5 mm for each outlet going downward. According to one embodiment, the discharge amount of the composition is exponentially increased as the number of opened discharge outlets 1130 increases.

[0064] In another embodiment, the slit widths of the discharge outlets 1130 may all be the same. For example, five discharge outlets 1130 may each have the same slit width of 1 mm. In one embodiment, the discharge amount increases uniformly in proportion to the number of opened discharge outlets 1130.

[0065] The device body 1100 according to an embodiment of the present invention may include recessed grooves 1140 formed longitudinally on both sides of the discharge outlet 1130 to allow the slide plate 1200 to be in contact with the discharge outlet 1130 and to guide the vertical movement of the slide plate 1200.

[0066] The recessed groove 1140 may have a concave (-shaped) cross-section. The recessed groove 1140 may be formed to match the thickness and height of the slide plate 1200 so that the slide plate 1200 can be inserted.

[0067] Portions of the left and right sides of the slide plate 1200 may be inserted into the recessed grooves 1140 to be vertically movable. The slide plate 1200 may move only in the longitudinal direction along the recessed grooves 1140.

[0068] The width of the recessed grooves 1140 may be formed to match the thickness of the slide plate 1200, so that the slide plate 1200 can be in contact with the discharge outlet 1130.

[0069] The device body 1100 may further include a plurality of rear locking grooves 1150, which are arranged in a row on right and left sides of the discharge outlet 1130, and to which rear locking protrusions 1220 to fix the slide plate 1200 moved vertically are coupled.

[0070] The rear locking grooves 1150 may be formed to correspond to positions in which the slide plate 1200 opens or closes each of the discharge outlets 1130.

[0071] In one embodiment, when the slide plate 1200 closes all the discharge outlets 1130, all of the rear locking grooves 1150 may be coupled to the rear locking protrusions of the slide plate 1200. When the slide plate 1200 is positioned to open only some of the discharge outlets 1130, the rear locking grooves 1150 may be coupled to a portion of the rear locking protrusions of the slide plate 1200.

[0072] The device body 1100 may further include a plurality of front locking grooves 1160, which are arranged in a row on the inner surfaces of the recessed grooves 1140, and to which the front locking protrusions 1210 to fix the slide plate 1200 moved vertically are coupled.

[0073] The front locking grooves 1160 may be formed to correspond to positions in which the slide plate 1200 opens or closes each of the discharge outlets 1130. The front locking grooves 1160 may be formed on surfaces facing the rear locking grooves 1150. The front locking grooves 1160 may be vertically offset from the rear locking grooves 1150.

[0074] The front and rear locking grooves 1160 and 1150 may be formed in a hemispherical or other concave shape to match the shape of the front and rear locking protrusions 1210 and 1220.

[0075] FIG. 6 is a perspective view illustrating a state in which the device body and the slide plate are coupled according to an embodiment of the present invention.

[0076] Referring to FIG. 6, the slide plate 1200 according to one embodiment of the present invention may be inserted into the device body 1100 and vertically slidable.

[0077] The slide plate 1200 may sequentially open or close the slit-shaped discharge outlets 1130 while moving vertically along the recessed grooves 1140.

[0078] The front and rear locking protrusions 1210 and 1220 formed on the front and rear surfaces of the slide plate 1200 may be respectively coupled to the front and rear locking grooves 1160 and 1150 formed in the device body 1100, thereby fixing the slide plate 1200 in position.

[0079] FIG. 7 is a side view illustrating the slide plate according to an embodiment of the present invention.

[0080] FIG. 8 is a front view and a rear view illustrating the slide plate according to an embodiment of the present invention.

[0081] Referring to FIGS. 7 and 8, the slide plate 1200 according to an embodiment of the present invention may be a T-shaped plate having a predetermined thickness. The slide plate 1200 may have a lateral length formed to match the spacing between the left and right recessed grooves 1140 to be inserted into the recessed grooves 1140.

[0082] The slide plate 1200 may include a handle 1230 that allows a user to grip and operate the slide plate 1200. In one embodiment, the side of the slide plate 1200 having the handle 1230 may be L-shaped.

[0083] A plurality of front locking protrusions 1210 may be formed in a row on the left and right sides of the slide plate 1200 to fix the position of the slide plate 1200 after the vertical movement. As described above, the front locking protrusions 1210 may be coupled to the front locking grooves 1160 of the device body 1100 to fix the position of the slide plate 1200.
