Description

Technical Field

[0001] The present invention relates to a packaging clip and a packaging box connected using the packaging clip, wherein the packaging clip connects two or more packaging pieces by overlapping and inserting the packaging clip into a packaging piece such as a corrugated sheet. Background Technology

[0002] In the past, when packaging large and heavy products such as electronic devices, the so-called C-type packaging box was widely used, in which the product was carried in the lower box and covered the upper box for fixation.

[0003] A packaging clip was designed that allows for easy disassembly from the connected state of the lower and upper boxes when opening this type of C-shaped packaging box. Summary of the Invention

[0004] The purpose of this invention is to provide a packaging clip that can improve conveying efficiency and delivery efficiency, as well as a packaging box connected using the packaging clip.

[0005] The first structure of the packaging clip of the present invention includes a base member and a key member. The base member has: a first cylindrical portion, which is inserted into the through holes of two or more packaging pieces having through holes, with the through holes overlapping; a flange portion, which is provided at a first opening edge on one end side of the first cylindrical portion; and a pair of hook members, which are respectively connected to opposite inner wall surfaces of the first cylindrical portion by means of a first hinge portion and are bent outward about a second opening edge on the other end side of the first cylindrical portion with the first hinge portion as the pivot. The key member has a second cylindrical portion that can be inserted and removed from the first opening edge relative to the first cylindrical portion of the base member, and the key member is orthogonal to the first hinge portion. The second hinge portion is connected to the flange portion. By passing the first cylindrical portion through the through hole from the second opening edge side and inserting the second cylindrical portion into the first cylindrical portion, the hook member rotates about the first hinge portion as the axis in the direction of the second opening edge side of the first cylindrical portion and protrudes outward from the second opening edge, and is opposite to the flange portion. The flange portion and the hook member clamp the two or more packages. In the absence of external force, the pair of hook members are configured in a cross-sectional wedge shape with their tops approaching each other. The opposite outer surfaces of the first cylindrical portion are respectively provided with a slope that slopes inward from the first opening edge toward the second opening edge.

[0006] Furthermore, the present invention relates to packaging boxes connected using packaging clips with the above-described structure.

[0007] According to the first structure of the present invention, when the packaging clips are overlapped, the tip of the hook member of the upper packaging clip is guided along the hook member of the lower packaging clip, allowing the second opening edge of the upper packaging clip to be smoothly inserted into the first opening edge of the lower packaging clip. This allows multiple packaging clips to be held in an overlapping state. Therefore, it is possible to reduce transport space, improve transport efficiency, and eliminate the possibility of packaging clips tangling or breaking during transport.

[0008] Furthermore, according to the second structure of the present invention, it becomes a packaging box that can be bundled and opened in simple steps. Attached Figure Description

[0025] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a perspective view showing a structural example of a packaging box 1 in which the packaging clip 10 of the present invention is installed. The packaging box 1 consists of a tray plate 2 with a pallet, an upper box 3, and a cushioning member 4 disposed on the tray plate 2 with the pallet.

[0026] The pallet 2 with a tray consists of a tray 5 and a tray plate 6 fixed to the lower surface of the tray 5. The tray 5 consists of a bottom surface 5a that supports the product (not shown) to be bundled, and side walls 5b that are erected around the perimeter of the bottom surface 5a. Buffer members 4 are positioned at predetermined gaps between the four corners of the bottom surface 5a and the side walls 5b. An elongated through hole 8a is formed in the center of each side wall 5b of the tray 5.

[0027] The upper box 3 covers the sides and top surface of the product and is a square tube with an open bottom. On the lower part of each side of the upper box 3, through holes 8b are formed at positions coinciding with the through holes 8a of the tray plate 2. Packaging clips 10 (see reference) are inserted when the through holes 8a and 8b are aligned. Figure 2 This connects the pallet 2 with the upper box 3 as a single unit.

[0028] The cushioning element 4 is made of corrugated paper or polystyrene foam to protect the product from external impacts. A product-bearing surface 4a is formed on the cushioning element 4 to match the shape of the product. A tongue (not shown) provided on the bottom surface 5a is inserted into the lower surface of the cushioning element 4, positioning and aligning each cushioning element 4 in a predetermined position without horizontal displacement. Alternatively, the cushioning element 4 can be fixed to the bottom surface 5a by other methods such as adhesive bonding.

[0029] The pallet 6 is composed of multiple support sections 6a formed by bending corrugated paper, and a top plate (not shown) and a bottom plate 6b fixed to the upper and lower surfaces of each support section 6a. Arm insertion holes 9 are formed between each support section 6a for inserting the arms of a forklift or a manual pallet trolley (pallet handling trolley).

[0030] Next, we will explain how to use it. Figure 1 The steps for packaging products in the shown box 1 are as follows: First, the product is placed on the product-bearing surface 4a of the cushioning member 4, which is positioned on the bottom surface 5a of the pallet 2. Next, cushioning members are also placed on the upper surface and sides of the product as needed. After covering the upper box 3, the side walls 5b of the pallet 2 are raised. Finally, packaging clips 10 are inserted with the through holes 8a in the side walls 5b coinciding with the through holes 8b in the upper box 3, thereby integrally connecting the pallet 2 and the upper box 3.

[0031] Figure 2 This is a perspective view of the packaging clip 10 of the first embodiment of the present invention before use, viewed from the side of the flange portion 17 (outside of the packaging box 1). Figure 3 This is a side view of the packaging clip 10 of the first embodiment before use, viewed from the extending direction of the first hinge portions 18a and 18b. Figure 4 This is a side cross-sectional view of the base member 14 of the packaging clip 10 of the first embodiment, viewed from the extending direction of the first hinge portions 18a and 18b. Figure 2 (A AA′ view section).

[0032] like Figures 2-4As shown, the packaging clip 10 is composed of a base member 14 and a key member 15 connected to the base member 14 via a connecting piece 23. The base member 14 has: a first cylindrical portion 16; a flange portion 17, a first opening edge 16a provided at one end of the first cylindrical portion 16; and a pair of hook members 19a, 19b, which are rotatably connected to the opposing inner surfaces of the first cylindrical portion 16 by means of first hinge portions 18a, 18b.

[0033] The flange portion 17 is provided with a recess 26 for receiving the connecting piece 23 of the key member 15 when it is inserted into the base member 14. A pair of pin holes 17a are formed on the two sides of the flange portion 17 parallel to the first hinge portions 18a and 18b. The pin holes 17a are semi-circular and open at the end edge of the flange portion 17.

[0034] like Figure 4 As shown, hook members 19a and 19b are respectively bent into an L-shape with the first hinge portions 18a and 18b as supports, extending outward from the second opening edge 16b on the other end side of the first cylindrical portion 16, and the top ends of hook members 19a and 19b protrude from the first cylindrical portion 16. Support ribs 35 are formed near the first hinge portions 18a and 18b. The support ribs 35 extend in the direction of extension of the first hinge portions 18a and 18b (…). Figure 4 They are formed in pairs by spacing them at predetermined intervals in a direction perpendicular to the paper.

[0035] The key member 15 has a second cylindrical portion 25, which has an outer dimension substantially the same as the inner dimension of the first cylindrical portion 16. The second cylindrical portion 25 can be inserted into the first cylindrical portion 16 of the base member 14 by bending the connecting piece 23 along the second hinge portion 24. A first insertion portion 27 (see reference) is provided through the upper surface of the key member 15. Figure 5 An inclined surface 28 with a circular arc cross-section is provided on the bottom surface of the first insertion part 27.

[0036] A locking portion 30 is provided on the end edge of the key member 15 opposite to the second hinge portion 24. The locking portion 30 has a support portion 31 and a locking claw 32. The support portion 31 is formed in a U-shape in side view, with the third opening edge 25a of one end side (upstream side in the insertion direction) of the second cylindrical portion 25 as the base end, and the fourth opening edge 25b of the other end side in the insertion direction ( Figure 2 Extending upwards (in the upward direction), and further extending towards the base end ( Figure 2 (bends downwards).

[0037] Near the top end of the support portion 31, in the support axis direction of the second hinge portion 24, which is orthogonal to the extending direction of the support portion 31 ( Figure 3At both ends of the first cylindrical part 16 (in the left and right directions), a pair of locking claws 32 are formed. When the second cylindrical part 25 is inserted into the interior of the first cylindrical part 16, the locking claws 32 engage with the engaged portion 40 (see reference) formed on the inner wall surface of the first cylindrical part 16 of the base member 14. Figure 5 The key member 15 is locked in place when the second cylindrical portion 25 is inserted into the first cylindrical portion 16 of the base member 14.

[0038] This describes the operation of connecting the packaging box 1 using the packaging clip 10 of the first embodiment configured as described above. First, the through-hole 8a in the side wall 5b of the tray plate 2 and the through-hole 8b in the upper box 3 (both refer to...) Figure 1 In the overlapping state, the base member 14 of the packaging clip 10 is inserted into the through holes 8a and 8b from the second opening edge 16b side of the first cylindrical portion 16 from the outside of the side wall 5b.

[0039] Next, through from Figure 2 The state causes the key member 15 to rotate along the second hinge portion 24 and fold back towards the base member 14, thereby causing the second cylindrical portion 25 to abut against the hook members 19a and 19b. Then, the second cylindrical portion 25 is inserted into the interior of the first cylindrical portion 16 from the side of the first opening edge 16a. As a result, the hook members 19a and 19b are pressed by the second cylindrical portion 25, and the hook members 19a and 19b rotate about the first hinge portions 18a and 18b as the rotation axis on the outside of the first cylindrical portion 16. Figure 4 Rotate (in the direction of the arrow).

[0040] Figure 5 This is a top view of the first embodiment of the packaging clip 10, viewed from the flange 17 side, showing the key member 15 inserted into the base member 14. Figure 6 This is a perspective view of the first embodiment of the packaging clip 10, showing the key member 15 inserted into the base member 14, viewed from the hook members 19a and 19b. Figure 7 It is the direction of extension from the first hinge parts 18a and 18b. Figure 5 (From the left) side view of the packaging clip 10 of the first embodiment, in which the key member 15 is inserted into the base member 14 and clamps the side wall 5b of the tray plate 2 with the tray and the upper box 3.

[0041] With the key member 15 (second cylindrical portion 25) fully inserted into the base member 14 (first cylindrical portion 16), the top ends of the hook members 19a and 19b, pressed by the second cylindrical portion 25, protrude substantially parallel to the first cylindrical portion 16 and the flange portion 17. At this time, as... Figure 7 As shown, the side wall 5b of the pallet 2 with tray and the upper box 3 are held by the flange 17 and hook members 19a and 19b.

[0042] In such Figure 7With the side wall 5b of the tray plate 2 connected to the upper box 3 as shown, if an external force is applied to rotate the hook members 19a and 19b inward, or even without an external force applied, the second cylindrical portion 25 is pushed back by the hook members 19a and 19b due to the restoring force of the first hinge portions 18a and 18b. Therefore, there is a possibility that the key member 15 and the base member 14 may disengage.

[0043] Therefore, the engaging portion 30 provided on the key member 15 and the engaging portion 40 provided on the base member 14 are used to maintain the engaging state between the key member 15 and the base member 14. If the key member 15 is rotated along the second hinge portion 24 and the second cylindrical portion 25 is inserted into the first cylindrical portion 16, the locking pawl 32 engages the engaging portion 40. As a result, the support portion 31 elastically deforms in the direction in which the locking pawl 32 leaves the engaging portion 40.

[0044] When the hook members 19a and 19b are fully rotated by the second cylindrical portion 25, the locking pawl 32 passes over the engaged portion 40, and the elastically deformable support portion 31 deforms towards the engaged portion 40 using the restoring force. Thus, as Figure 5 As shown, the locking claw 32 engages with the lower part of the engaged portion 40, thus firmly maintaining the engaged state between the key member 15 and the base member 14.

[0045] When the packaging clip 10 is removed, the support portion 31 elastically deforms in the direction that the locking claw 32 moves away from the engaged portion 40, thereby releasing the engagement between the locking claw 32 and the engaged portion 40. As a result, the tray plate 2 with the pallet can be separated from the upper box 3.

[0046] Figure 8 This is a side cross-sectional view showing the overlapping state of the two packaging clips 10 of the first embodiment, viewed from the extending direction of the first hinge portions 18a and 18b. Figure 8 As shown, if the packaging clips 10 overlap, the tops of the hook members 19a and 19b of the upper packaging clip 10 enter between the hook members 19a and 19b of the lower packaging clip 10. This limits the offset of the overlapping packaging clips 10.

[0047] At this time, without the application of external force, the opposing hook members 19a and 19b are arranged in a cross-sectional wedge shape with their tips approaching each other. Therefore, the tips of the hook members 19a and 19b of the upper packaging clip 10 are guided along the hook members 19a and 19b of the lower packaging clip 10, making it easy for the packaging clips 10 to overlap each other.

[0048] Furthermore, on the side of the first cylindrical portion 16 of the packaging clip 10, a slope θ (10° in this embodiment) is provided that slopes inward from the first opening edge 16a toward the second opening edge 16b. That is, the outer diameter of the second opening edge 16b is smaller than the outer diameter of the first opening edge 16a. Therefore, when the packaging clips 10 are overlapped, the second opening edge 16b (lower end) of the upper packaging clip 10 can be smoothly inserted into the first opening edge 16a of the lower packaging clip 10.

[0049] Furthermore, the slope θ is not limited to 10°. If the slope θ is too small, the packaging clips 10 will be difficult to overlap. On the other hand, if the slope θ is too large, the overlapping posture of the packaging clips 10 will be unstable. Therefore, the slope θ is preferably around 5° to 15°.

[0050] Furthermore, when the packaging clips 10 are overlapped, the second opening edge 16b of the upper packaging clip 10 contacts the support rib 35 of the lower packaging clip 10. At this time, the outer surface of the upper first cylindrical portion 16 and the inner surface of the lower first cylindrical portion 16, as well as the upper hook members 19a, 19b and the lower hook members 19a, 19b, are kept separate from each other. Therefore, it is possible to prevent the packaging clips 10 from sticking together and being unable to separate due to dimensional defects caused by warping during the forming of the packaging clips 10, shrinkage caused by temperature changes, etc.

[0051] Figure 9 This is a perspective view showing the overlapping state of four packaging clips 10 according to the first embodiment. (As shown) Figure 9 As shown, the upper packaging clip 10 is rotated 180° relative to the lower packaging clip 10 and overlaps. As a result, the key members 15 protrude differently from each other from the base member 14, so that the upper and lower adjacent key members 15 do not interfere with each other when the packaging clips 10 are overlapped.

[0052] Next, the delivery method of the packaging clip 10 in the first embodiment will be described. Figure 10 This is a perspective view showing a stack 101 of multiple packaging clips 10 of the first embodiment being supported on a support platform 50. Figure 11 It is a perspective view showing that multiple support platforms 50, divided by partition 51, respectively support the stack of clips 101. Figure 12 This is a perspective view showing the state in which the stack of clips 101 supported on the support platform 50 is stored in the transport container 200.

[0053] like Figures 10-12As shown, by supporting a stack 101 of multiple overlapping packaging clips 10 on a support platform 50 and storing it in a transport container 200, the transport space for the packaging clips 10 can be made more compact compared to the case where they are loosely placed in a bag. In addition, the possibility of the packaging clips 10 becoming entangled or damaged due to vibration and impact during transport is also eliminated.

[0054] Furthermore, when using an automatic assembly device (feeder) to feed out the packaging clips 10, such as Figure 13 As shown, two pins 71 of the feeder 70 are inserted into the pair of pin holes 17a of the packaging clip 10, which is located at the top of the clip stack 101. Then, the pins 71 are moved inward to clamp the packaging clip 10 and lift it upward. As a result, the posture of the packaging clip 10 is restricted to a horizontal state, and the overlap of the packaging clips 10 can be smoothly released, allowing the packaging clips 10 to be fed out one by one from the clip stack 101.

[0055] According to this embodiment, multiple packaging clips 10 can be held in an overlapping state without being tightly attached to each other. Therefore, the conveying space can be reduced and the conveying efficiency can be improved. In addition, since the packaging clips 10 can be picked up using an automatic assembly device, the bundling operation using the packaging clips 10 is also improved.

[0056] Figure 14 This is a perspective view of the packaging clip 10 of the second embodiment of the present invention before use, viewed from the flange portion 17 side. Figure 15 This is a perspective view of the packaging clip 10 of the second embodiment, viewed from the flange 17 side, before the key member 15 is inserted into the first cylindrical part 16. Figure 16 This is a side cross-sectional view of the packaging clip 10 of the second embodiment, viewed from the extending direction of the first hinge portions 18a and 18b, showing the key member 15 inserted into the first cylindrical portion 16.

[0057] In the packaging clip 10 of this embodiment, an inclined surface 80 is formed on the second cylindrical portion 25 of the key member 15. Furthermore, a limiting protrusion 81 is formed on the outer surface of the second cylindrical portion 25. Additionally, abutment ribs 82 are formed on the opposing surfaces of the hook members 19a and 19b opposite to the second cylindrical portion 25. The structure of the other parts of the packaging clip 10 is the same as in the first embodiment.

[0058] like Figure 14 and Figure 15 As shown, the inclined surface 80 moves from the second hinge portion 24 side of the second cylindrical portion 25 toward the engaging portion 30 side (rotating end side) towards the fourth opening edge 25b. Figure 15The fourth opening edge 25b is inclined downwards and reaches the fourth opening edge 25b. By forming an inclined surface 80 in the second cylindrical portion 25, the contact area of ​​the fourth opening edge 25b relative to the hook members 19a, 19b is reduced when the second cylindrical portion 25 is inserted inside the first cylindrical portion 16. More specifically, the fourth opening edge 25b only contacts the center portion of the hook members 19a, 19b in the long side direction (the extending direction of the first hinge portions 18a, 18b).

[0059] Therefore, when the second cylindrical portion 25 is inserted into the interior of the first cylindrical portion 16, the load from the second cylindrical portion 25 is applied only to the central portion along the long side of the hook members 19a and 19b. This reduces the load required for opening and closing the hook members 19a and 19b, improving the operability of the packaging clip 10.

[0060] In addition, such as Figure 15 and Figure 16 As shown, near the third opening edge 25a on the engaging portion 30 side (rotating end side) of the second cylindrical portion 25, a pair of limiting protrusions 81 are formed in a direction perpendicular to the extending direction of the first hinge portions 18a and 18b. If the second cylindrical portion 25 is inserted into the interior of the first cylindrical portion 16, the pair of limiting protrusions 81 are respectively opposite to the upper surfaces of the first hinge portions 18a and 18b.

[0061] If the second cylindrical portion 25 is inserted into a predetermined position inside the first cylindrical portion 16, the limiting protrusion 81 abuts against the upper surface (limiting surface) of the first hinge portions 18a and 18b, thus limiting the insertion of the second cylindrical portion 25. This suppresses excessive pushing of the second cylindrical portion 25 into the first cylindrical portion 16, thereby preventing deformation or damage to the packaging clip 10.

[0062] In addition, such as Figure 16 As shown, with the second cylindrical portion 25 inserted into the interior of the first cylindrical portion 16, abutment ribs 82 are formed on the opposing surfaces of the hook members 19a and 19b opposite to the second cylindrical portion 25. Figure 14 As shown, abutment ribs 82 are formed at two locations on each of the hook members 19a and 19b, for a total of four locations.

[0063] like Figure 16 As shown, when the packaging clip 10 is in the installed state, sometimes a direction is applied to the hook members 19a and 19b to release the installed state of the packaging clip 10 (in the hook member 19a, the direction is...). Figure 16 The counterclockwise direction is in the hook component 19b. Figure 16(clockwise direction) load. In this case, if a force is applied from the hook members 19a and 19b in the direction of pushing up the fourth opening edge 25b of the second cylindrical portion 25, there is a possibility that the second cylindrical portion 25 will disengage from the first cylindrical portion 16 and the installation state of the packaging clip 10 will be released.

[0064] Therefore, by forming abutment ribs 82 on the opposing surfaces of the hook members 19a and 19b opposite to the second cylindrical portion 25, the fourth opening edge 25b of the second cylindrical portion 25 does not contact the hook members 19a and 19b. As a result, even if a load is applied to the hook members 19a and 19b in the direction of releasing the installation state, no force is applied in the direction of pushing the fourth opening edge 25b of the second cylindrical portion 25 upward. Therefore, the accidental release of the installation state of the packaging clip 10 can be prevented in advance.

[0065] In addition, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, in the first embodiment described above, in the extending direction of the first hinge portions 18a, 18b ( Figure 4 Support ribs 35 are formed in pairs at predetermined intervals in a direction perpendicular to the paper surface. However, support ribs 35 may also be formed in three or more locations in the extension direction of the first hinge portions 18a and 18b.

[0066] Furthermore, in the second embodiment described above, the upper surfaces of the first hinge portions 18a and 18b are provided as limiting surfaces that abut against the limiting protrusion 81. However, limiting surfaces that abut against the limiting protrusion 81 may also be provided independently of the first hinge portions 18a and 18b.

[0067] Furthermore, the packaging clip 10 for packaging box 1 described in the above embodiments is used in packaging box 1, which uses a tray 2 consisting of a tray 5 and a pallet 6. However, the packaging clip 10 of the present invention can also be applied to packaging box 1 consisting only of upper box 3 and tray 5 without the pallet 6.

[0068] This invention can also be applied to packaging clips that connect two or more packaging components by overlapping and inserting holes formed in a packaging piece such as a corrugated sheet. By utilizing this invention, packaging clips that improve conveying and delivery efficiency, as well as packaging boxes connected using these clips, can be provided.

Without the application of external force, the pair of hook members are configured in a wedge shape with their cross-sections facing each other towards the tips. The opposite outer surfaces of the first cylindrical portion are respectively provided with slopes that slope inward from the edge of the first opening toward the edge of the second opening. A support rib is formed near the first hinge portion. When the packaging clips are overlapped, the support rib contacts the second opening edge of the upper packaging clip. When the second opening edge of the upper packaging clip contacts the support rib of the lower packaging clip, the outer surface of the upper first cylindrical portion and the inner surface of the lower first cylindrical portion, as well as the upper hook member and the lower hook member, are kept separate from each other. The second cylindrical portion has: a third opening edge on the upstream side in the insertion direction into the first cylindrical portion; and a fourth opening edge on the downstream side in the insertion direction. Each of the pair of hook members has an abutment rib formed thereon, and the abutment rib abuts against the outer side of the second cylindrical part inserted into the first cylindrical part, so that the fourth opening edge of the second cylindrical part does not contact the pair of hook members.

2. The packaging clip according to claim 1, characterized in that, The slope is 5° to 15°.

3. The packaging clip according to claim 1, characterized in that, The support ribs are formed in two or more at predetermined intervals in the extending direction of the first hinge portion.

4. The packaging clip according to claim 1, characterized in that, A pair of pin holes for inserting the feeder pins are formed on the two sides of the flange portion that are parallel to the first hinge portion.

5. The packaging clip according to claim 1, characterized in that, The key member has a locking portion that locks in place when the second cylindrical portion is inserted into the first cylindrical portion. The engaging portion has: a side-view U-shaped support portion that is elastically deformable; and a locking claw formed in the support portion, which engages with the engaging portion formed inside the first cylindrical portion.

6. The packaging clip according to claim 1, characterized in that, An inclined surface is formed in the second cylindrical portion, which inclines from the second hinge portion side toward the rotating end side of the key member toward the edge of the fourth opening and reaches the edge of the fourth opening.

7. The packaging clip according to claim 1, characterized in that, A limiting protrusion is formed on the outer side of the second cylindrical portion. A limiting surface is formed in the first cylindrical portion, and when the second cylindrical portion is inserted into a predetermined position, the limiting surface abuts against the limiting protrusion.

8. A packaging box, characterized in that, The connection is made using the packaging clips as described in any one of claims 1 to 7.
