Description

Lid opening and closing tool

[0001] The present invention relates to a lid opening and closing tool. More specifically, the present invention relates to a lid opening and closing tool for attaching a lid to a container or separating a lid attached to a container.

[0002] In a reagent production process involving attaching a lid to a container containing a reagent, an operator may position the container containing the reagent on a torque tester device and secure the container using a fixing member of the torque tester device. The operator may then screw the lid onto the secured container using a grip tool until a preset torque value is measured by the torque tester device. Here, screw threads are formed on the top of the container and the inner side of the lid, respectively, and the lid can rotate on the top of the container through these threads to completely cap the container. For example, if the lid is attached to the container with a torque value lower than the preset value, the reagent may leak from the container or the lid may detach; therefore, it is important to attach the lid to the container with a torque value greater than the preset value. However, performing the capping operation in this manner may require a relatively large amount of time and significantly reduce the production rate of the reagent production process.

[0003] In contrast, a worker can manually tighten the lid on a container containing reagents without using a torque tester device. For example, the worker can hold the container with their left hand and the lid with their right hand, and then attach the lid to the container. However, when proceeding in this manner, it is difficult to attach the lid to the container beyond a preset torque value because the tightening force varies among workers. In other words, the lid may rotate relatively less on the top of the container, and the lid may not be completely capped to the container. Additionally, since the size of both the container and the lid is relatively small and an uneven pattern is formed on the outer surface of the lid to increase friction, repeatedly tightening the lid on the container by hand may cause blisters or pain in the worker's hands.

[0004] The objective of the present invention is to provide a lid opening and closing tool.

[0005] However, the present invention is not limited to the purposes described above and may be extended in various ways without departing from the spirit and scope of the invention.

[0006] To achieve the aforementioned objective of the present invention, a lid opening and closing tool for attaching a lid to a container or separating a lid attached to a container according to exemplary embodiments of the present invention may include a body, a connecting unit connected to one side of the body, a torque variable unit connected to the other side of the body and determining a rotation torque of the connecting unit, and a lid opening and closing member that is detachably coupled to the connecting unit and includes a first recess where the lid is to be positioned.

[0007] In exemplary embodiments, a first uneven pattern is formed on the outer surface of the lid, and a second uneven pattern may be formed on the inner surface of the first recess so as to interlock with the first uneven pattern of the lid.

[0008] In exemplary embodiments, the first uneven pattern may be formed entirely along the profile of the outer surface of the lid, and the second uneven pattern may be formed entirely along the profile of the inner surface of the first recess.

[0009] In exemplary embodiments, when the lid is located inside the first recess of the lid opening / closing member, the lid can be fixed in the first recess.

[0010] In exemplary embodiments, the diameter of the first recess may be the same as the diameter of the lid.

[0011] In exemplary embodiments, when the lid is located inside the first recess of the lid opening / closing member, the lid opening / closing member may surround the lid.

[0012] In exemplary embodiments, the lid opening / closing member may include a first member comprising the first recess and a second recess formed to be detachably coupled to the connecting unit, and may include a second member located on the first member.

[0013] In exemplary embodiments, the connecting unit and the first member each comprise metal, and the lid and the second member each may comprise plastic.

[0014] In exemplary embodiments, the connecting unit may include a ball plunger located on the side of the first end.

[0015] In exemplary embodiments, the second recess of the second member may include a first through-opening that penetrates the second recess from the outside.

[0016] In exemplary embodiments, when the lid opening / closing member is coupled to the connecting unit, the ball plunger may be located in the first through opening.

[0017] In exemplary embodiments, the second recess has a cuboid shape, and the first end of the connecting unit may have the cuboid shape corresponding to the shape of the second recess.

[0018] In exemplary embodiments, the second recess of the second member may include a second through-opening that penetrates the second recess from the outside.

[0019] In exemplary embodiments, the lid opening / closing member may further include a fastening member detachably coupled to the second through-opening.

[0020] In exemplary embodiments, after the lid opening / closing member is connected to the connecting unit, when the fastening member is coupled to the second member through the second through-opening, the fastening member may come into contact with the first end of the connecting unit.

[0021] In exemplary embodiments, a screw thread is formed in the second through-opening, and the fastening member may be a bolt.

[0022] In exemplary embodiments, the first member may be fixed to the second member.

[0023] In exemplary embodiments, a first screw thread may be formed on the upper surface of the container, and a second screw thread corresponding to the first screw thread may be formed on the inner surface of the lid.

[0024] In exemplary embodiments, when the lid is attached to the container using the lid opening / closing tool, the lid can be attached to the container with a preset torque value.

[0025] To achieve the aforementioned objective of the present invention, a lid opening and closing tool for attaching a lid having a first uneven pattern formed on an outer surface to a container or separating a lid attached to a container according to exemplary embodiments of the present invention, wherein the lid opening and closing tool comprises a body, a ball plunger located on the side of a first end, a connecting unit connected to one side of the body, a torque variable unit connected to the other side of the body and determining a rotation torque of the connecting unit, and a lid opening and closing member having a first recess where the lid is to be positioned and detachably coupled to the connecting unit, wherein the lid opening and closing member may include a first member having a first recess having a second uneven pattern formed on an inner surface to engage with the first uneven pattern of the lid, and a second member having a second recess formed to be detachably coupled to the connecting unit and positioned on the first member.

[0026] A lid opening and closing tool according to exemplary embodiments of the present invention comprises a lid opening and closing member having a second uneven pattern formed therein that can engage with a first uneven pattern of the lid, thereby enabling the lid to be attached to a container with a rotational torque value greater than a preset value, and allowing the operator to repeatedly perform the capping operation with relatively little force. Accordingly, the lid opening and closing tool can significantly increase the production rate of a reagent production process performed manually by an operator, and can also protect the operator's hand because the operator's hand does not come into direct contact with the lid.

[0027] In addition, since the shapes of the first end and the second recess, respectively, of the connecting unit in the lid opening / closing member have a cuboid shape, the connecting unit and the second recess can have a relatively high bonding force. Accordingly, the rotational torque of the lid opening / closing tool can be accurately transmitted to the lid.

[0028] Furthermore, since the lid opening / closing member includes a fastening member, when the fastening member contacts the first end of the connecting unit, the ball plunger of the connecting unit can be more closely attached to the first through opening. Accordingly, the connecting unit connected to the body and the torque variable unit can be prevented from being separated from the lid opening / closing member in the fifth direction.

[0029] Meanwhile, when separating a lid that is relatively strongly attached to a container, the worker can easily separate the lid from the container with relatively little force using a lid opening / closing tool, and the worker's hand can also be protected because the worker's hand does not come into direct contact with the lid.

[0030] However, the effects of the present invention are not limited to the effects described above, and may be extended in various ways without departing from the spirit and scope of the present invention.

[0041] FIG. 1 is a perspective view showing a lid opening / closing tool according to exemplary embodiments of the present invention, FIG. 2 is a drawing showing a container and a lid, and FIG. 3 is a perspective view for explaining the process of tightening a lid on a container using the lid opening / closing tool of FIG. 1. Here, FIG. 1(a) is a perspective view showing a state in which the lid coupling member is not coupled to the connecting unit, and FIG. 1(b) is a perspective view showing a state in which the lid coupling member is coupled to the connecting unit. Also, FIG. 2(a) is a perspective view showing a state in which the lid is completely capped on the container, FIG. 2(b) is a perspective view showing a state in which the lid is separated from the container, and FIG. 2(c) is a top view showing the lid. For example, the lid opening / closing tool may be implemented as an opening / closing tool for coupling the lid to the container or separating the lid from the container.

[0042] Referring to FIGS. 1, 2, and 3, the lid opening / closing tool (100) may include a body (110), a connecting unit (130), a torque variable unit (150), a lid opening / closing member (200), etc. Here, the connecting unit (130) may include a ball plunger (170), and the lid opening / closing member (200) may include a first member (210) and a second member (250). Additionally, as shown in FIG. 2, a reagent may be contained in the container (10), and a first screw thread (15) may be formed on the upper surface of the container (10). A second screw thread (25) corresponding to the first screw thread (15) may be formed on the inner surface of the lid (20), and a first uneven pattern (30) may be formed on the outer surface of the lid (20). Furthermore, when the lid (20) is rotated clockwise, the lid (20) can be attached to the container (10), and when the lid (20) is rotated counterclockwise, the lid (20) can be separated from the container (10). In exemplary embodiments, the lid (20) may have a first diameter (G1).

[0043] The body (110) may have a bar shape extending in a first direction (D1). One side of the body (110) may be adjacent to a connecting unit (130), and the other side of the body (110) may be adjacent to a torque variable unit (150). The portion where the other side of the body (110) and the torque variable unit (150) are located may be the portion where an operator grips the lid opening / closing tool (100). The body (110) may include metal materials such as aluminum (Al), iron (Fe), zinc (Zn), lead (Nb), tungsten (W), copper (Cu), platinum (Pt), nickel (Ni), titanium (Ti), palladium (Pd), magnesium (Mg), calcium (Ca), lithium (Li), chromium (Cr), tantalum (Ta), molybdenum (Mo), scandium (Sc), neodymium (Nd), iridium (Ir), alloys such as aluminum-containing alloys, silver-containing alloys, copper-containing alloys, molybdenum-containing alloys, and metal nitrides such as aluminum nitride (AlN), tungsten nitride (WN), titanium nitride (TiN), chromium nitride (CrN), tantalum nitride (TaN), etc. In other exemplary embodiments, the body (110) may include a plastic such as polyether ether ketone, polyacrylate ketone, polyether imide, polyether sulfone, etc.

[0044] The connecting unit (130) may be connected to one side of the body (110), and the connecting unit (130) may extend from the body (110) in a second direction (D2). Here, the first direction (D1) and the second direction (D2) may be substantially orthogonal, the first direction (D1) and the fourth direction (D4) may be substantially opposite directions, and the second direction (D2) and the fifth direction (D5) may be substantially opposite directions. The connecting unit (130) may be rotatable clockwise (R1) or counterclockwise (R2) around the second direction (D2) as an axis, depending on the rotation setting of the lid opening / closing tool (100). For example, as illustrated in FIG. 1(a), when the rotation setting of the lid opening / closing tool (100) is in the first mode, the connecting unit (130) can rotate counterclockwise (R2) while connected to the body (110), and when the rotation setting of the lid opening / closing tool (100) is in the second mode, the connecting unit (130) can rotate clockwise (R1) while connected to the body (110). In other words, in the first mode, the connecting unit (130) does not move clockwise (R1) while connected to the body (110), and in the second mode, the connecting unit (130) does not move counterclockwise (R2) while connected to the body (110). Here, the rotation of the connecting unit (130) is defined as the connecting unit (130) rotating while the body (110) and the torque variable unit (150) are fixed.

[0045] A ball plunger (170) may be positioned on the side of the first end of the connecting unit (130), and the ball plunger (170) may protrude in a third direction (D3) from the side of the first end of the connecting unit (130). Here, the first and second directions (D1, D2) and the third direction (D3) may be substantially orthogonal, and the third direction (D3) and the sixth direction (D6) may be substantially opposite to each other. Additionally, the second end of the connecting unit (130) may be connected to the body (110). In exemplary embodiments, the first end of the connecting unit (130) may have a substantially cuboidal shape, and the ball plunger (170) may be positioned on one side of the cuboid. For example, the ball plunger (170) may include a socket, an elastic member disposed on the bottom surface inside the socket, and a ball in contact with the elastic member. The elastic member may be compressed or expanded along the longitudinal direction of the socket, and the ball may be positioned so that only a portion of it is exposed at the opening of the socket. When the exposed ball comes into contact with an object, the exposed ball may move into the interior of the socket regardless of the direction of contact between the object and the exposed ball, and the elastic member may be compressed. That is, a portion of the ball plunger (170) may be located inside the connecting unit (130), and the remainder of the ball plunger (170) (i.e., the exposed ball) may be exposed to the outside of the connecting unit (130). The connecting unit (130) and the ball plunger (170) may each comprise a metal, an alloy, a metal nitride, etc. Optionally, the connecting unit (130) and the ball plunger (170) may each comprise a plastic.

[0046] For convenience of explanation, the ball plunger (170) is described as protruding in a third direction (D3); however, since the connecting unit (130) is rotatable, the ball plunger (170) may be described as protruding in various directions depending on the position in which the connecting unit (130) is rotated. That is, the ball plunger (170) may protrude from the side of the connecting unit (130) in a direction perpendicular to the side.

[0047] The torque variable unit (150) can be connected to the other side of the body (110), and the torque variable unit (150) can determine the rotation torque of the connecting unit (130). For example, an arbitrary rotation torque value can be set through the torque adjustment screw of the torque variable unit (150), and when the lid (20) is tightened to the maximum extent on the container (10) through the lid opening / closing tool (100), the lid opening / closing tool (100) can prevent force from being applied to the lid (20) exceeding the set rotation torque value. However, in the present invention, the function of setting the arbitrary rotation torque value can be used when the operator screws the lid (20) on the container (10) with a preset torque value. In addition, the arbitrary rotation torque value may be changed depending on the type of container (10), the type of lid (20), etc. The torque variable unit (150) may include metal, alloy, metal nitride, etc. Optionally, the torque variable unit (150) may include plastic.

[0048] The lid opening / closing member (200) may be detachably coupled to the connecting unit (130). The lid opening / closing member (200) may include a first recess (220) where the lid (20) is to be positioned and a second recess (260) formed to be detachably coupled to the connecting unit (130) (see FIGS. 4 and 5). A detailed description of the lid opening / closing member (200) is provided with reference to FIGS. 4 and 5.

[0049] As illustrated in FIG. 3, in the first mode, the body (110) and the torque variable unit (150) can rotate counterclockwise (R2) around the connecting unit (130) as an axis. Here, the rotation of the body (110) and the torque variable unit (150) is defined as the body (110) and the torque variable unit (150) rotating as a single unit while the connecting unit (130) is fixed to the lid opening / closing member (200). Additionally, in the first mode, the body (110), the torque variable unit (150), the connecting unit (130), and the lid opening / closing member (200) can rotate as a single unit clockwise (R1). In the first mode, the body (110), the torque variable unit (150), the connecting unit (130), and the lid opening / closing member (200) rotate together in a clockwise direction (R1), so that the lid (20) coupled to the lid opening / closing member (200) can also rotate in a clockwise direction (R1), and the lid (20) can be coupled to the container (10). For example, in the first mode, the operator can grasp the container (10) with their left hand, grasp the body (110) and the torque variable unit (150) with their right hand, move the right hand in a counterclockwise direction (R2), and then move the right hand in a clockwise direction (R1). Here, when the right hand is moved counterclockwise (R2), only the body (110) and the torque variable unit (150) can rotate as a single unit, and when the right hand is moved clockwise (R1), the body (110), the torque variable unit (150), the connecting unit (130), and the lid opening / closing member (200) can rotate as a single unit clockwise (R1). By the operator repeatedly performing the above operation, the lid (20) can be attached to the container (10).

[0050] In contrast, in the second mode, the body (110) and the torque variable unit (150) can rotate clockwise (R1) around the connecting unit (130) as an axis. Here, the rotation of the body (110) and the torque variable unit (150) is defined as the body (110) and the torque variable unit (150) rotating as a single unit while the connecting unit (130) is fixed to the lid opening / closing member (200). Additionally, in the second mode, the body (110), the torque variable unit (150), the connecting unit (130), and the lid opening / closing member (200) can rotate as a single unit counterclockwise (R2). In the second mode above, the body (110), the torque variable unit (150), the connecting unit (130), and the lid opening / closing member (200) rotate together in a counterclockwise direction (R2), so that the lid (20) coupled to the lid opening / closing member (200) can also rotate in a counterclockwise direction (R2), and the lid (20) coupled to the container (10) can be separated. For example, in the second mode above, the operator can grasp the container (10) with their left hand, grasp the body (110) and the torque variable unit (150) with their right hand, move the right hand clockwise (R1), and then move the right hand counterclockwise (R2). Here, when the right hand is moved clockwise (R1), only the body (110) and the torque variable unit (150) can rotate as a single unit, and when the right hand is moved counterclockwise (R2), the body (110), the torque variable unit (150), the connecting unit (130), and the lid opening / closing member (200) can rotate as a single unit clockwise (R1). By the operator repeatedly performing the above operation, the lid (20) attached to the container (10) can be separated from the container (10).

[0051] In a conventional reagent production process in which a lid (20) is attached to a container (10) containing a reagent, the operator may position the container (10) containing the reagent on a torque tester device and then fix the container (10) using a fixing member of the torque tester device, and until a preset torque value is measured on the torque tester device, the operator may tighten the lid (20) on the fixed container (10) using a grip tool. Here, screw threads are formed on the upper surface of the container (10) and on the inner surface of the lid (20), respectively, and through the screw threads, the lid (20) can rotate on the upper surface of the container (10) so that the lid (20) can be completely capped to the container (10). For example, if the lid (20) is attached to the container (10) with a torque value less than the preset torque value, the reagent leaks from the container (10) or the lid (20) separates from the container (10); therefore, it is important to attach the lid (20) to the container (10) with a torque value greater than the preset torque value. However, if the capping operation is performed in this manner, a relatively large amount of time may be required, and the production rate of the reagent production process may be significantly reduced.

[0052] Alternatively, the operator may manually tighten the lid (20) on the container (10) containing the reagent without using the torque tester device. For example, the operator may grasp the container (10) with their left hand and the lid (20) with their right hand, and then attach the lid (20) to the container (10). However, when performing the work in this manner, it is difficult to attach the lid (20) to the container (10) beyond the preset torque value because the tightening force of the lid (20) varies from operator to operator. In other words, the lid (20) may rotate relatively less on the top of the container (10), and the lid (20) may not be completely capped to the container (10). Additionally, since the size of each of the container (10) and the lid (20) is relatively small and an uneven pattern is formed on the outer surface of the lid (20) to increase friction, when the worker repeatedly tightens the lid (20) to the container (10) by hand, blisters may form on the worker's hand or cause pain in the hand.

[0053] In exemplary embodiments, when the operator attaches the lid (20) to the container (10) using the lid opening / closing tool (100), the lid (20) can be attached to the container (10) with a rotational torque value greater than or equal to a preset value. Accordingly, the operator can perform the capping operation repeatedly with relatively little force, and the operator's hand can also be protected because the operator's hand does not come into direct contact with the lid (20).

[0054] FIGS. 4 and 5 are drawings showing a lid coupling member included in the lid opening and closing tool of FIG. 1.

[0055] Referring to FIGS. 1, 2, 4 and 5, a second member (250) may be positioned on a first member (210), and the first member (210) may be fixed to the second member (250). Here, the first member (210) may include a first recess (220), and the first recess (220) of the first member (210) may be recessed in a fifth direction (D5), and a second irregular pattern (230) may be formed on the inner surface of the first recess (220) of the first member (210). Additionally, the second member (250) may include a second recess (260), a first through-opening (270), and a second through-opening (280), and the second recess (260) of the second member (250) may be recessed in a second direction (D2). Furthermore, the first through opening (270) can be penetrated in the third direction (D3) from the second recess (260), and the second through opening (280) can be penetrated in the sixth direction (D6) from the second recess (260).

[0056] For convenience of explanation, the first and second through openings (270, 280) are described as penetrating from the second recess (260) into the third and sixth directions (D3, D6), respectively; however, since the lid opening / closing member (200) connected to the connecting unit (130) is rotatable, the first and second through openings (270, 280) may also be described as penetrating from the second recess (260) into various directions depending on the position in which the connecting unit (130) is rotated. That is, the first and second through openings (270, 280) may be penetrating from the outside into the second recess (260).

[0057] However, although the first through opening (270) and the second through opening (280) are illustrated as facing each other in the present invention, the configuration of the present invention is not limited thereto. For example, in other exemplary embodiments, the first through opening (270) and the second through opening (280) may not face each other.

[0058] Referring again to FIGS. 2(c), 3, and 4(b), when viewed in the second direction (D2), the first uneven pattern (30) of the lid (20) may include a plurality of triangles, said plurality of triangles may be formed entirely along the profile of the outer surface of the lid (20), and the lid (20) may have a first diameter (G1). For example, the first uneven pattern (30) may be formed on the lid (20) to increase the frictional force of the lid (20) when the lid (20) attached to the container (10) is separated or the lid (20) is attached to the container (10). Each of the container (10) and the lid (20) may include plastic.

[0059] Additionally, when viewed in the second direction (D2), the second uneven pattern (230) of the first member (210) may include a plurality of triangles, and said plurality of triangles may be formed entirely along the profile of the inner surface of the first recess (220), and the first recess (220) may have a first diameter (G1). That is, the diameter of the first recess (220) may be substantially the same as the diameter of the lid (20). In exemplary embodiments, the second uneven pattern (230) of the first recess (220) may be formed to interlock with the first uneven pattern (30) of the lid (20). In other words, when the lid (20) is positioned inside the first recess (220) of the lid opening / closing member (200), the lid (20) may be fixed in the first recess (220). Additionally, when the lid (20) is positioned inside the first recess (220) of the lid opening / closing member (200), the lid opening / closing member (200) may surround the lid (20). The first member (210) may comprise plastic. In exemplary embodiments, the first member (210) may be manufactured using polyether ether ketone having a relatively low weight, relatively high rigidity, and relatively high chemical resistance. For example, because the first member (210) has a relatively low weight, the total weight of the lid opening / closing member (200) can be reduced. Also, because the first member (210) has a relatively high rigidity, the second uneven pattern (230) of the first member (210) may not wear out even if the lid (20) is repeatedly attached to the container (10) through the lid opening / closing tool (100). Furthermore, since the first member (210) has relatively high chemical resistance, the first member (210) may not corrode even if a reagent contained in the container (10) comes into contact with the first member (210).

[0060] Referring again to FIGS. 1, 3, and 5, the second recess (260) of the second member (250) may be located at the center of the upper surface of the second member (250), and the second recess (260) may substantially have a cuboid shape. In exemplary embodiments, the first end of the connecting unit (130) may have a cuboid shape corresponding to the shape of the second recess (260). For example, the size of the cuboid of the second recess (260) may be substantially the same as the size of the cuboid of the connecting unit (130), and the connecting unit (130) may be fitted into the second recess (260). Since the shape of each of the first end and the second recess (260) of the connecting unit (130) is a cuboid shape, when the body (110), torque variable unit (150), connecting unit (130), and lid opening / closing member (200) rotate together in a clockwise direction (R1) in the first mode of the lid opening / closing tool (100) (or when the body (110), torque variable unit (150), connecting unit (130), and lid opening / closing member (200) rotate together in a counterclockwise direction (R2) in the second mode of the lid opening / closing tool (100), the connecting unit (130) and the second recess (260) can have a relatively high bonding force, and the rotational torque of the lid opening / closing tool (100) can be accurately transmitted to the lid (20).

[0061] Additionally, when a lid opening / closing member (200) (or a second member (250)) is connected to the connecting unit (130) through the second recess (260), the ball plunger (170) of the connecting unit (130) may be positioned in the first through-opening (270). In other words, when a worker connects the lid opening / closing member (200) to the connecting unit (130), the ball plunger (170) of the connecting unit (130) may rotate the second member (250) according to the position so that the ball plunger (170) is positioned in the first through-opening (270), thereby connecting the lid opening / closing member (200) to the connecting unit (130). That is, as illustrated in FIG. 1(a), the operator can visually check the position of the ball plunger (170) (e.g., the ball plunger (170) protruding in the third direction (D3)), and as illustrated in FIG. 1(b), after aligning the position of the first through opening (270) formed on the outer surface of the second member (250) (e.g., located in the third direction (D3)) with the position of the ball plunger (170), the lid opening / closing member (200) can be attached to the connecting unit (130). Here, since the first through opening (270) penetrates from the outside into the second recess (260), the first through opening (270) formed in the second recess (260) functions as a space where the ball plunger (170) is located, and the first through opening (270) formed on the outer surface of the second member (250) can function as an alignment mark for aligning the positions of the ball plunger (170) and the first through opening (270). For example, when the ball plunger (170) is located in the first through opening (270), the separation of the connecting unit (130) connected to the body (110) and the torque variable unit (150) from the lid opening / closing member (200) in the fifth direction (D5) can be relatively reduced.

[0062] Furthermore, the lid opening / closing member (200) may further include a fastening member (300), and the fastening member (300) may be detachably coupled to the second through-opening (280). Here, as shown in FIGS. 5(b) and 5(c), a screw thread (290) may be formed in the second through-opening (280), and the fastening member (300) may include a bolt that can be fastened to the screw thread (290). For example, after the lid opening / closing member (200) is connected to the connecting unit (130), when the fastening member (300) is coupled to the second member (250) through the second through-opening (280), the fastening member (300) may come into contact with the first end of the connecting unit (130). In exemplary embodiments, when the fastening member (300) contacts the first end of the connecting unit (130), the ball plunger (170) of the connecting unit (130) may be more closely attached to the first through opening (270). In this case, the connecting unit (130) connected to the body (110) and the torque variable unit (150) may be prevented from being separated from the lid opening / closing member (200) in the fifth direction (D5).

[0063] The second member (250) may include a metallic material, an alloy, a metal nitride, etc. In exemplary embodiments, the second member (250) may be made of hard anodized aluminum. Since the surface strength of the second member (250) can be further increased through the hard anodizing coating, the part in contact between the second member (250) and the second member (250) may not wear out even if the lid (20) is repeatedly attached to the container (10) through the lid opening / closing tool (100).

[0064] According to exemplary embodiments of the present invention, the lid opening / closing tool (100) includes a lid opening / closing member (200) having a second uneven pattern (230) formed therein that can engage with a first uneven pattern (30) of the lid (20), thereby enabling the lid (20) to be attached to the container (10) with a rotational torque value greater than or equal to a preset value, and allowing the operator to repeatedly perform the capping operation with relatively little force. Accordingly, the lid opening / closing tool (100) can significantly increase the production rate of the reagent production process performed manually by the operator, and the operator's hand can also be protected because the operator's hand does not come into direct contact with the lid (20).

[0065] Additionally, since the shape of each of the first end and the second recess (260) of the connecting unit (130) in the lid opening / closing member (200) has a cuboid shape, the connecting unit (130) and the second recess (260) can have a relatively high bonding force. Accordingly, the rotational torque of the lid opening / closing tool (100) can be accurately transmitted to the lid (20).

[0066] Furthermore, since the lid opening / closing member (200) includes a fastening member (300), when the fastening member (300) contacts the first end of the connecting unit (130), the ball plunger (170) of the connecting unit (130) can be more closely attached to the first through opening (270). Accordingly, the connecting unit (130) connected to the body (110) and the torque variable unit (150) can be prevented from being separated from the lid opening / closing member (200) in the fifth direction (D5).

[0067] Meanwhile, when separating the lid (20) that is relatively strongly attached to the container (10), the worker can easily separate the lid (20) from the container (10) with relatively little force using the lid opening / closing tool (100), and the worker's hand can also be protected because the worker's hand does not come into direct contact with the lid (20).

[0068] FIGS. 6, 7, 8, and 9 are drawings for illustrating lid coupling members corresponding to various lids. The lid opening / closing members (201, 202) exemplified in FIGS. 7 and 9 may have a configuration substantially identical or similar to the lid opening / closing member (200) of the lid opening / closing tool (100) described with reference to FIGS. 1 through 5, except for the shape and / or diameter size of the second uneven pattern. In FIGS. 6, 7, 8, and 9, redundant descriptions of components substantially identical or similar to those described with reference to FIGS. 1 through 5 are omitted.

[0069] Referring to FIGS. 6 and 7, a container (11) may contain a reagent, and a first screw thread may be formed on the upper surface of the container (11). A second screw thread corresponding to the first screw thread may be formed on the inner surface of the lid (21), and a first uneven pattern (31) may be formed on the outer surface of the lid (21). Furthermore, when the lid (21) is rotated clockwise, the lid (21) may be coupled to the container (11), and when the lid (21) is rotated counterclockwise, the lid (21) may be separated from the container (11). In exemplary embodiments, the lid (21) may have a first diameter (G1). When viewed in the second direction (D2), the first uneven pattern (31) of the lid (21) may include a plurality of trapezoids, and the plurality of trapezoids may be formed entirely along the profile of the outer surface of the lid (21). For example, the first uneven pattern (31) may be formed on the lid (21) to increase the frictional force of the lid (21) when separating the lid (21) attached to the container (11) or attaching the lid (21) to the container (11).

[0070] Additionally, when viewed in the second direction (D2), the second uneven pattern (231) of the first member (211) may include a plurality of trapezoids, and said plurality of trapezoids may be formed entirely along the profile of the inner surface of the first recess (221), and the first recess (221) may have a first diameter (G1). That is, the diameter of the first recess (221) may be substantially the same as the diameter of the lid (21). In exemplary embodiments, the second uneven pattern (231) of the first recess (221) may be formed to interlock with the first uneven pattern (31) of the lid (21). In other words, when the lid (21) is positioned inside the first recess (221) of the lid opening / closing member (201), the lid (21) may be fixed in the first recess (221). Additionally, when the lid (21) is located inside the first recess (221) of the lid opening / closing member (201), the lid opening / closing member (201) can surround the lid (21).

[0071] Referring to FIGS. 8 and 9, a container (12) may contain a reagent, and a first screw thread may be formed on the upper surface of the container (12). A second screw thread corresponding to the first screw thread may be formed on the inner surface of the lid (22), and a first uneven pattern (32) may be formed on the outer surface of the lid (22). Furthermore, when the lid (22) is rotated clockwise, the lid (22) may be coupled to the container (12), and when the lid (22) is rotated counterclockwise, the lid (22) may be separated from the container (12). In exemplary embodiments, the lid (22) may have a second diameter (G2) smaller than the first diameter (G1). When viewed in the second direction (D2), the first uneven pattern (32) of the lid (22) may include a plurality of rectangles, and the plurality of rectangles may be formed entirely along the profile of the outer surface of the lid (22). For example, the first uneven pattern (32) may be formed on the lid (22) to increase the frictional force of the lid (22) when separating the lid (22) attached to the container (12) or attaching the lid (22) to the container (11).

[0072] Additionally, when viewed in the second direction (D2), the second uneven pattern (232) of the first member (212) may include a plurality of rectangles, and said plurality of rectangles may be formed entirely along the profile of the inner surface of the first recess (222), and the first recess (222) may have a second diameter (G2). That is, the diameter of the first recess (222) may be substantially the same as the diameter of the lid (22). In exemplary embodiments, the second uneven pattern (232) of the first recess (222) may be formed to interlock with the first uneven pattern (32) of the lid (22). In other words, when the lid (22) is positioned inside the first recess (222) of the lid opening / closing member (202), the lid (22) may be fixed in the first recess (222). Additionally, when the lid (22) is located inside the first recess (222) of the lid opening / closing member (202), the lid opening / closing member (202) can surround the lid (22).

[0073] As described above, the lid opening and closing member according to exemplary embodiments of the present invention can be manufactured in various forms to correspond to various types of lids.

[0074] Although the foregoing description refers to exemplary embodiments of the present invention, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the invention as set forth in the following claims.

[0075] The present invention can be applied to various opening and closing tools for attaching a lid to a container or separating a lid attached to a container. For example, it can be applied to lid opening and closing tools that attach a lid to a container with a torque value greater than a preset value in a manual reagent production process.
