Technical Field

[0001] This utility model belongs to the field of packaging technology, and specifically relates to a self-positioning watch strap packaging liner and packaging box. Background Technology

[0002] With the development of technology, more and more smart wearable devices have emerged. These smart wearable devices, such as bracelets and watches, all use watch straps. Moreover, with people's pursuit of beauty, most watch straps and watch heads in smart wearable devices have detachable connection structures, making it easy for people to change watch straps to suit different outfits. Therefore, watch straps have become a separate product.

[0003] The packaging structure of watch straps typically includes an outer box and an inner lining. The inner lining is usually made of blister packaging, paper-plastic packaging, or velvet packaging. Therefore, it usually has the disadvantages of needing to develop molds, which leads to long production cycles and high costs. At the same time, blister packaging also poses environmental problems.

[0004] Therefore, in view of the above shortcomings, this utility model is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a self-limiting watch strap packaging liner and packaging box, so as to at least partially solve the above-mentioned technical problems.

[0006] The first aspect of this utility model provides a self-limiting watch strap packaging liner, comprising:

[0007] The first frame includes a flat plate portion and a strip hole disposed on the flat plate portion;

[0008] The second skeleton includes a rectangular groove and an adhesive portion connected to the outer periphery of the groove. The adhesive portion is bonded to the side of the flat plate portion, and the opening of the groove corresponds to the strip hole.

[0009] The limiting card includes a card plate and four wing plates disposed on both sides of the card plate. The four wing plates are bonded together in pairs to form two limiting rings. The side of the card plate facing away from the limiting rings is bonded to the groove.

[0010] Both the second frame and the limiting card are foldable structures.

[0011] The self-limiting watch strap packaging liner provided by this utility model may also have the following additional technical features:

[0012] In one specific embodiment of this utility model, the first frame further includes two supporting flanges, which are respectively connected to both sides of the flat plate portion, and the free ends are folded toward one side of the second frame.

[0013] In one specific embodiment of this utility model, the maximum distance between the free end of the supporting flange and the flat plate is greater than the depth of the groove.

[0014] In one specific embodiment of this utility model, the first frame further includes a pull-out handle, which is formed by folding the end of the flat plate portion, and the folding direction of the pull-out handle is opposite to the folding direction of the supporting flange.

[0015] In one specific embodiment of this utility model, the limiting ring is formed into a rectangle along the cross section perpendicular to the length direction of the card plate.

[0016] In one specific embodiment of this utility model, among the two wing plates that are adapted and bonded, two creases are formed on the wing plate located inside the limiting ring, and one crease is formed on the other wing plate. The wing plates are folded towards each other along the creases, and are adapted and bonded at least partially overlapping.

[0017] In one specific embodiment of this utility model, the groove includes a groove bottom and four side walls connected to the groove bottom. There are four adhesive parts, and the side walls and adhesive parts are arranged in a one-to-one correspondence. Each adhesive part is at least partially connected to the corresponding side wall.

[0018] In one specific embodiment of this utility model, the length direction of the first skeleton is taken as the first direction, and the width direction of the first skeleton is taken as the second direction; the length of the two adhesive portions located at both ends of the first direction along the second direction is the same as the length of the plate along the second direction; and / or the length of the second skeleton along the second direction is the same as the length of the plate along the second direction, and both ends of the two adhesive portions located at both ends of the second direction along the first direction are provided with avoidance notches to avoid the other two adhesive portions.

[0019] In one specific embodiment of this utility model, along the length direction, one end of the card plate is formed as a step, and one of the limiting rings is disposed on the step; the bottom of the groove is provided with a supporting step adapted to the step.

[0020] The second aspect of this utility model also includes a packaging box, comprising a box body and a self-positioning watch strap packaging liner as described in any one of the above, wherein the self-positioning watch strap packaging liner is disposed within the box body.

[0036] Reference Figures 1-5 The first aspect of this utility model provides a self-positioning watch strap packaging liner 100, including a first frame 10, a second frame 20, and a positioning clip 30. The first frame 10 includes a flat plate portion 11 and a strip-shaped hole 14 disposed on the flat plate portion 11. The second frame 20 includes a rectangular groove 21 and an adhesive portion 24 connected to the outer periphery of the groove 21. The adhesive portion 24 is adhered to the side of the flat plate portion 11, and the opening of the groove 21 corresponds to the strip-shaped hole 14. The positioning clip 30 includes a clip plate 31 and four wing plates disposed on both sides of the clip plate 31. The four wing plates are adhered in pairs to form two positioning rings 32. The side of the clip plate 31 facing away from the positioning rings 32 is pasted into the groove 21. The second frame 20 and the positioning clip 30 are both foldable structures.

[0037] Specifically, the first frame 10 is formed as a flat structure, and the second frame 20 and the limiting card 30 are both formed by folding flat structures. The folded second frame 20 is structurally stable by being glued to the first frame 10 through the adhesive part 24, forming a groove 21. The limiting ring 32 of the limiting card 30 is formed by folding and gluing, and the limiting card 30 is fixed to the groove 21 by gluing and can fix the two ends of the watch strap through the two limiting rings 32. In this way, the watch strap is fixed. Then, the self-limiting watch strap packaging liner 100 is placed in the box of the packaging box to realize the storage and packaging of the watch strap.

[0038] In this embodiment, the second skeleton 20 and the limiting card 30 are set as folding structures, so that no mold opening operation is required during processing, thereby effectively reducing processing costs and increasing its application rate.

[0039] In one specific embodiment of this utility model, the first frame 10 further includes two supporting flanges 12, which are respectively connected to both sides of the flat plate portion 11, and the free ends are folded toward the second frame 20. This facilitates the placement of the self-positioning watch strap packaging liner 100 inside the packaging box.

[0040] In some embodiments, the maximum distance between the free end of the supporting flange 12 and the flat plate portion 11 is greater than the depth of the groove 21.

[0041] Specifically, the support flange 12 is formed into a rectangle, and the two flanges are symmetrically arranged.

[0042] This embodiment limits the size of the supporting flange 12, so that the second frame 20 can be suspended inside the packaging box, thereby reducing the impact between the watch strap and the inner wall of the packaging box when it falls, and thus effectively avoiding damage to the watch strap.

[0043] In some embodiments, the first frame 10 further includes a pull-out handle 13, which is formed by folding the end of the flat portion 11, and the folding direction of the pull-out handle 13 is opposite to the folding direction of the supporting flange 12. The self-locking watch strap packaging liner 100 can be removed from the packaging box by pulling out the handle 13, thereby making it convenient for the user to remove the watch strap.

[0044] Optionally, the number of pull-out handles 13 is one or two. When there are two, they can be located at both ends of the flat plate 11 along the length direction.

[0045] In some embodiments, the limiting ring 32 is formed into a rectangle along a cross section perpendicular to the length direction of the card plate 31. Thus, when the limiting card 30 is fixed to the second frame 20, the two side walls 23 of the limiting ring 32 fit and abut against the side walls 23 of the groove 21, thereby improving the structural stability of the limiting ring 32.

[0046] In some embodiments, of the two wing plates that are adapted for bonding, the wing plate located inside the limiting ring 32 has two creases, and the other wing plate has one crease. The wing plates are folded towards each other along the creases, and are adapted for bonding at least partially overlapping positions.

[0047] Specifically, the wing plate with two creases can surround the retaining plate 31 in the folded state, and the surrounding structure is rectangular in cross-section along the length direction perpendicular to the retaining plate 31. This ensures that the limiting ring 32 is rectangular in cross-section along the length direction perpendicular to the retaining plate 31. The overlapping parts of the two wing plates are fitted and bonded together to form the limiting ring 32. Optionally, the bonding portion 24 of the two wing plates includes at least the two adjacent sides of the limiting ring 32. Optionally, the two wing plates are bonded together with double-sided adhesive.

[0048] This embodiment ensures that the limiting ring 32 has a rectangular cross-section along the length direction perpendicular to the card plate 31 through the above-mentioned settings. Furthermore, the above-mentioned settings are also beneficial for positioning the wing plate, thereby facilitating subsequent pasting operations.

[0049] In some embodiments, the groove 21 includes a groove bottom 22 and four sidewalls 23 connected to the groove bottom 22. There are four adhesive portions 24, and the sidewalls 23 and adhesive portions 24 are arranged in a one-to-one correspondence. Each adhesive portion 24 is at least partially connected to the corresponding sidewall 23.

[0050] Specifically, creases are formed at the connection points of the sidewalls 23 with the groove bottom 22 and the adhesive portion 24. Thus, the four sidewalls 23 are folded along the fold at the connection point with the groove bottom 22 toward the same side of the groove bottom 22 to form a groove 21 with one open side with the groove bottom 22. At the same time, the adhesive portion 24 is folded along another crease to the opposite side to be flush with the groove opening of the groove 21. Then, the adhesive portion 24 is bonded to the flat plate portion 11 to make the second skeleton 20 have a relatively fixed structure, thereby having better structural stability.

[0051] In this embodiment, the second skeleton 20 is formed into a folded structure through the above-described structure.

[0052] In some embodiments, the length direction of the first skeleton 10 is taken as the first direction, and the width direction of the first skeleton 10 is taken as the second direction; the length of the two adhesive portions 24 located at both ends of the first direction along the second direction is the same as the length of the plate along the second direction; and / or the length of the second skeleton 20 along the second direction is the same as the length of the plate along the second direction, and the two adhesive portions 24 located at both ends of the second direction are provided with avoidance notches at both ends of the first direction to avoid the other two adhesive portions 24.

[0053] This embodiment, through the aforementioned dimensional limitations, utilizes the four side edges of the flat plate 11 to limit the positioning of the adhesive portion 24, thereby improving the assembly consistency between the first frame 10 and the second frame 20, and thus increasing the yield rate. Simultaneously, this embodiment also avoids mutual interference between the adhesive portions 24 by providing corner avoidance features in the adhesive portion 24.

[0054] In some embodiments, along the length direction, one end of the card plate 31 is formed as a step 33, and a limiting ring 32 is disposed on the step 33, and a support step adapted to the step 33 is provided in the groove bottom 22.

[0055] Specifically, along the length direction, the end of the card plate 31 has two spaced creases that fold in opposite directions, thus forming a step 33 at one end of the card plate 31. Correspondingly, the groove bottom 22 of the second frame 20 also has two creases that fold in opposite directions to form a supporting step that matches the step 33.

[0056] It should be noted that, since the bottom of the groove 22 has a supporting step 33, the side of the bottom of the groove 22 from the crease to one end of the supporting step is cut off from the side wall 23 along the first direction.

[0057] In this embodiment, a step 33 is set to create a height difference between the two limiting rings 32. This is to accommodate the height difference formed when long and short watch straps are stacked, thereby helping to keep the watch strap in a horizontal state and reducing the movement space of the watch strap in the groove 21. This also ensures that the end of the watch strap does not have enough space to flip over when it is dropped, effectively preventing the watch strap from being dented or damaged.

[0058] The second aspect of this utility model also includes a packaging box, comprising a box body and a self-positioning watch strap packaging liner 100 as described above, wherein the self-positioning watch strap packaging liner 100 is disposed within the box body. The structure of the self-positioning watch strap packaging liner 100 is as described in the above embodiments. The packaging box in this embodiment includes the self-positioning watch strap packaging liner 100 as described in all the above embodiments, and therefore also possesses at least the beneficial effects of the above embodiments.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
