[0039] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a clip 100 with an electronic tag according to an exemplary embodiment of the present application.

[0040] The present application provides a clip 100 with an electronic tag, which can be clamped on the packaging bag of goods to accurately manage the goods in the warehouse. For example, the electronic tag can be used to obtain information such as the entry and exit time and shelf life of the goods. The electronic tag can be an RFID chip using radio frequency identification technology, but is not limited to this. The application scenarios of the clip 100 are not limited, such as factory warehouses, restaurant kitchens, etc.

[0041] Please refer to Figure 2 and Figure 3 , Figure 2 for Figure 1 A top view of the clip 100 is shown in FIG. Figure 3 It is a schematic diagram of the first packaging bag 200 being tightened by the tie mouth portion 20 .

[0042] The clip 100 includes a base 10, a tie portion 20 and a clamping portion 30. The tie portion 20 is provided on the base 10, and the tie portion 20 includes a restraining opening 21, and the restraining opening 21 is for a tieable first packaging bag 200 to pass through, so that the first packaging bag 200 is tightened at the opening end, thereby binding the clip 100 with the product information in the first packaging bag 200. The first packaging bag 200 can be a packaging bag for opened goods, and after the opening end of the first packaging bag 200 is tightened, it can prevent moisture or foreign matter from entering, and can also ensure the safety of the goods.

[0043] Please refer to Figure 4 and Figure 5 , Figure 4 It is a schematic diagram of the clamping portion 30 in a deformed state. Figure 5 It is a schematic diagram of the clamping portion 30 clamping the second packaging bag 300 .

[0044] The clamping part 30 is connected to the base 10, and the clamping part 30 is deformable and can be in a first position and a second position. In the first position, a gap 40 is formed between the clamping part 30 and the base 10. In the second position, the clamping part 30 and the base 10 can clamp the sealed edge of the second packaging bag 300 in the gap 40, wherein the clamping force comes from the force acting on the sealed edge of the second packaging bag 300 when the clamping part 30 recovers its deformation. The second packaging bag 300 can be an unopened packaging bag.

[0045] According to the above description, the clip 100 can be used to clamp at least two packaging bags, for example, one is a first packaging bag 200 that has been opened and needs to be tied, and the other is an unopened second packaging bag 300. In this way, the clip 100 can be used on at least two packaging bags of different forms, with more application scenarios and a wider range of adaptability.

[0046] Please continue to refer to Figure 2 , the present application does not limit the specific structure of the clamping portion 30. In the present embodiment, the clamping portion 30 is arranged as a cantilever structure, one end of the clamping portion 30 is a connecting end 31, the connecting end 31 is connected to the base 10, and the other end of the clamping portion 30 is a free end 32, and the free end 32 is deformable relative to the base 10. For example, in a first deformation state, the free end 32 is in a first position, and in a second deformation state, the free end 32 may be in a second position. For example, applying a downward external force to the free end 32 may cause the free end 32 to bend downward and deform to reach the first position, and conversely, when the external force is removed, the free end 32 recovers the deformation and reaches the second position. The amount of deformation of the free end 32 is determined by the length of the cantilever. The clamping portion 30 has a simple structure and is easy to deform, and there is no need to separately set up elastic parts, etc.

[0047] Please combine Figure 2 and Figure 5 In one embodiment, the free end 32 includes a first surface 320 for clamping the second packaging bag 300, and the first surface 320 is provided with a protrusion 321 protruding from the first surface 320. In this way, the protrusion 320 protrudes toward the second packaging bag 300 and contacts the second packaging bag 300, providing resistance for the second packaging bag 300 to escape from the gap 40, ensuring that the second packaging bag 300 is reliably clamped and fixed.

[0048] In an optional embodiment, the protrusion 321 is configured as a pointed protrusion, and the further away from the first surface 320, the smaller the cross-sectional area of ​​the protrusion 321. The "cross-sectional area" mentioned here refers to the area of ​​the cross section obtained by cutting the protrusion 321 with a plane perpendicular to the protruding direction of the protrusion 321. The top area of ​​the pointed protrusion is small, thereby reducing the contact area between the protrusion 321 and the second packaging bag 300, thereby increasing the pressure and improving the reliability of clamping.

[0049] In one embodiment, in order to facilitate the placement of the second packaging bag 300 into the gap 40, a guide surface 3210 may be provided on the protrusion 321, and the guide surface 3210 is directed from the free end 32 to the connecting end 31 ( Figure 2 That is, the inclination direction of the guide surface 3210 is set to be consistent with the direction when the second packaging bag 300 is placed in the gap 40, which can reduce the difficulty of placing the second packaging bag 300 in the gap 40 and improve smoothness.

[0050] The number of protrusions 321 is not limited, and one or more protrusions 321 may be provided. In this embodiment, the latter is adopted. That is, a plurality of protrusions 321 are provided on the first surface 320, and the plurality of protrusions 321 are arranged in a plurality of rows along the direction from the free end 32 to the connection end 31. The purpose of such arrangement is that the plurality of rows of protrusions 321 can form a plurality of resistances for the second packaging bag 300 to fall off, which can further reduce the risk of the second packaging bag 300 falling off.

[0051] exist Figure 2 and Figure 5 In the illustrated embodiment, the plurality of protrusions 321 are arranged in two rows, each row having a plurality of protrusions 321, and the plurality of protrusions 321 in each row are arranged at intervals and arranged in a straight line. Optionally, the number of protrusions 321 in each row may be different. For example, the number of protrusions 321 in one row is three, and the number of protrusions 321 in the other row is two.

[0052] In one embodiment, Figure 2As shown, the base 10 is also provided with a guide channel 12 connected to the constraint port 21. One end of the guide channel 12 that passes through the outer edge of the base 10 is the entrance end for placing the first packaging bag, and the end of the guide channel 12 that is connected to the constraint port 21 is the connection end. The guide channel 12 can be used to guide the first packaging bag 200 into the constraint port 21. The guide channel 12 can be a tapered channel from large to small, that is, the opening at the entrance end is large and the opening at the connection end is small, so that the mouth of the first packaging bag 200 can be tightened in the process of passing through the guide channel 12. The constraint port 21 can be a circular port or a square port, which is not limited in this application.

[0053] In one embodiment, Figure 2 As shown, the clamping portion 30 and the base 10 are set as an integrated structure, and the clamping portion 30 is cut and formed on the base 10. The cutting method can be stamping, and for conductive materials, it can also be formed by wire cutting. In this way, no additional connector is required to connect the clamping portion 30 and the base 10, and the structure is simple and easy to form.

[0054] A disconnected break 41 is formed between the clamping portion 30 and the base 10 , one end of the break 41 is a head end 410 , and the other end is a tail end 411 . The clamping portion 30 is connected to the base 10 at the location where the head end 410 and the tail end 411 are disconnected.

[0055] In one embodiment, the break 41 includes a sub-break 412 perpendicular to the direction in which the free end 32 points to the connecting end 31, and the sealed edge of the second packaging bag 300 can be clamped at the sub-break 412. At the sub-break 412, the base 10 is provided with a support leg 11 extending toward the connecting end 31. In this way, the support leg 11 can also provide a force in the same direction as the extension of the support leg 11 to the sealed edge of the second packaging bag 300, and the force can provide resistance to the second packaging bag 300 from coming out, further preventing the second packaging bag 300 from coming out of the gap 40.

[0056] In an optional embodiment, the support leg 11 is a pointed support leg, and the closer to the connecting end 31, the smaller the cross-sectional area of ​​the support leg 11. The "cross-sectional area" mentioned here refers to the area of ​​the cross section of the support leg 11 obtained by cutting the support leg 11 with a plane perpendicular to the extension direction of the support leg 11. The small top area of ​​the pointed support leg can reduce the contact area with the second packaging bag 300, thereby increasing the pressure and preventing the second packaging bag 300 from slipping out of the gap 40.

[0057] For example, a plurality of legs 11 may be provided on the base 10, and the sub-slits 412 may also be provided with multiple sections, and the plurality of legs 11 may be respectively provided in different sub-slits 412. In this embodiment, two legs 11 are provided, and the two legs 11 are provided in two sub-slits 421, and the two legs 11 are arranged in a straight line in a direction perpendicular to the X direction.

[0058] exist Figure 2 In the embodiment shown, the support leg 11 is disposed between two adjacent rows of the protrusions 321 and is staggered with the protrusions 321. In this way, the protrusions 321 and the support leg 11 can act on multiple different parts of the second packaging bag 300, so that the second packaging bag 300 can be subjected to the anti-falling force at multiple parts, making the force distribution more uniform.

[0059] like Figure 3 As shown, in one embodiment, the sub-break 412 is provided with multiple sections. From the free end 32 to the direction of the connecting end 31, the sub-break at the front end is the first sub-break 4121, and the sub-break at the rear end is the second sub-break 4122. Among the plurality of protrusions 321, a part of the protrusions 321 are arranged at the edge of the first surface 320 along the first sub-break 4121, and the rest of the protrusions 321 are arranged at the edge of the first surface 320 along the second sub-break 4122. In this way, the number of protrusions 321 does not need to be too large. Moreover, the spacing between the two rows of protrusions 321 at the front end and the rear end is also relatively large, which can effectively prevent the second packaging bag 300 from slipping out.

[0060] exist Figure 3 In the illustrated embodiment, there are two first sub-breaks 4121 at the front end, a protrusion 321 is provided along each first sub-break 4121 , and three protrusions 321 are provided along the first sub-breaks 4121 , and the three protrusions 321 may be evenly distributed.

[0061] In one embodiment, Figure 3 As shown, the clamping portion 30 is formed inside the base 10, that is, the clamping portion 30 is formed within the contour of the base 10, and the slit 41 does not penetrate to the outer edge of the base 10. In this way, the base 10 disposed outside the clamping portion 30 can protect the clamping portion 30 and prevent the clamping portion 30 from being broken or deformed beyond recovery due to excessive force.

[0062] In one embodiment, Figure 3As shown, the clamping portion 30 includes a T-shaped end and a square end connected to each other, and the small end of the T-shaped end is connected to the square end. The T-shaped end is the free end 32, and the square end is the connecting end 31. The free end 32 is set as a T-shaped end, which can not only ensure the clamping area, but also can be deformed under a small force, which is simple to operate and labor-saving.

[0063] In one embodiment, the clip 100 is a card-type clip, the base 10 is a flat plate base, and the clamping portion 30 is cut and formed, which has a simple structure, is easy to manufacture and has low cost. The material of the plate base is not limited, including but not limited to metal.

[0064] Please combine Figure 1 and Figure 6 , Figure 6 for Figure 1 . In one embodiment, the clip 100 further includes an electronic tag for recording product information disposed on the clamping portion 30, and the electronic tag includes an RFID chip. RFID technology can perform non-contact two-way data communication through wireless radio frequency, and read and write the recording medium (electronic tag or radio frequency card) through wireless radio frequency, so as to achieve the purpose of identifying the target and exchanging data, and is simple and convenient to use.

[0065] In one embodiment, the electronic tag may be disposed above the clamping portion 30 , for example, the electronic chip may be covered by a cover 70 , thereby protecting the electronic tag.

[0066] Please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of a clip 400 according to another exemplary embodiment of the present application, wherein the free end is in an initial position. Figure 8 for Figure 7 Schematic diagram of the free end shown in the first position.

[0067] In one embodiment, the clip 400 is curved, for example, it can be a U-shaped clip, but it is not limited thereto, and it can also be an S-shaped clip, an M-shaped clip, an N-shaped clip, etc. The U-shaped clip is used as an example for description here.

[0068] In one embodiment, the free end 401 of the clip 400 is provided with a first clamp 402, and the base 403 of the clip 400 is further provided with a second clamp 404. When the free end 401 is not pressed or deformed, it is in an initial position (refer to Figure 7), in the initial position, the first clamp 401 and the second clamp 404 are arranged side by side, for example, the first clamp 401 is located above the second clamp 404. In the first position, the first clamp 402 is located below the second clamp 404, and the gap 405 is formed, and the gap 405 is for the second packaging bag 300 to be placed. In the second position, the first clamp 402 abuts against the second clamp 404 from below, so as to clamp the edge of the second packaging bag 300 in the gap 405 (refer to Fig.10 ). In this configuration, the first clamp 402 is located below the second clamp 404, and the first clamp 402 is hindered from restoring its deformation by the second clamp 404, so that the edge of the second packaging bag 300 can be clamped more reliably.

[0069] In one embodiment, one of the first clamp 402 and the second clamp 404 can be configured as a pointed clamp, which can increase the contact area between the first clamp 402 and the second clamp 404 when they abut against each other, thereby increasing the contact area with the sealed edge of the second packaging bag 300, further increasing the reliability of clamping. In addition, the pointed clamp can also make the sealed edge of the clamped second packaging bag 300 more curved, thereby greatly reducing the risk of slipping out.

[0070] It should be noted that when pressing the free end 401, the pressure can be applied in the direction opposite to the first clamp 402 and the second clamp 404, or the force can be applied from the free end 401 to the bending part of the U-shaped clamp (refer to Figure 7 The wear of the first chuck 402 and the second chuck 404 can be reduced.

[0071] In one embodiment, the first clamp 402 is provided with a first contact surface 4020 facing the second clamp 404, and the second clamp 404 is provided with a second contact surface 4040 facing the first clamp 402. During the deformation from the initial position to the first position, the first contact surface 4020 slides along the second contact surface 4040, so that the first clamp 402 moves to the bottom of the second clamp 402, and the first contact surface 4020 and / or the second contact surface 4040 are arranged to move along the sliding direction ( Figure 7 The first contact surface 4020 and / or the second contact surface 4040 are arranged to be inclined so as to reduce the difficulty of the first clamp 402 moving to the bottom of the second clamp 402, reduce the damage to both, and improve the smoothness of the movement of the first clamp 402. In this embodiment, the first contact surface 4020 and the second contact surface 4040 are both arranged to be inclined surfaces.

[0072] In one embodiment, one end of the clip 400 is the free end 401, and the free end 401 is further provided with a plate body 405 located on the side of the first clamp 402 and facing away from the second clamp 404, and a groove 406 is provided between the plate body 405 and the first clamp 402, and the groove 406 is used to accommodate the second clamp 404 when the free end 401 is in the first position and the second position, and the plate body 405 is closer to the end of the free end 401 than the first clamp 402. In this way, the part where the first clamp 402 and the second clamp 404 match can be located below and behind the plate body 405, which can protect the matching part on the one hand, and provide a hand-held part for the user on the other hand, so that the user can apply force to the free end 401 conveniently.

[0073] Please refer to Fig. 9 and Fig.10 , Fig. 9 yes Figure 7 FIG. 1 is a schematic diagram showing a first packaging bag 200 being tightened by the cuff of the clip. Fig.10 yes Figure 7 Schematic diagram of the clamping portion of the clip clamping the sealed edge of the second packaging bag 300.

[0074] exist Fig. 9 In the embodiment shown, the base 401 of the clip 400 is provided with a constriction portion 407. Figure 2 The structure of the constriction portion 21 shown in FIG. 1 is basically the same and will not be repeated here.

[0075] exist Fig.10 In the illustrated embodiment, the sealed edge of the second packaging bag 300 is clamped between the first clamp 402 and the second clamp 404 , and the sealed edge is curved at the clamping position, so the risk of slipping out is low.

[0076] The electronic tag (not shown) is disposed on the clamping portion 408 of the clip 400, for example, can be disposed on a side surface of the clamping portion 408 facing the internal space. The electronic tag can be covered inside by a cover to avoid exposure, but is not limited to this.

[0077] The clips 100, 400 provided in the present application have a small number of parts, a simple structure, low cost and are not easy to damage. Taking the application scenario of a smart kitchen as an example, the goods in the smart kitchen are generally fresh food. The clips 100, 400 are easily contaminated with oil when used. The structure of the clips 100, 400 is more convenient for daily cleaning. In addition, when two different fixing methods are required when the food package is opened and unopened, the clip 100 can not only clamp the edge of the unopened food packaging bag, but also tighten the mouth of the opened food packaging bag. It is more convenient to use in the smart kitchen, with a lower threshold, higher compatibility and longer service life.
