[0021] In addition, fold lines may be formed by single score lines, single half-cut lines, perforation lines, cut lines, short slit lines, half-cut lines, indentation lines, or any combination thereof, and the present disclosure is not limited thereto.

[0022] Referring to FIG. 1, FIG. 1 illustrates an unfolded schematic view of a two-handle packaging structure 100 according to an embodiment of the present disclosure. The two-handle packaging structure 100 includes a bottom 110, two foldable areas 120, two first supporting portions 130, two second supporting portions 140, two third supporting portions 150, two fourth supporting portions 160, two rib portions 170 and two handles 180.

[0023] The bottom 110 includes a plurality of fitting holes 111, which are disposed at two opposite sides of the bottom 110. The foldable areas 120 are connected to the other two opposite sides of the bottom 110. The first supporting portions 130 are connected to two opposite sides of one of the foldable areas 120, and the second supporting portions 140 are connected to two opposite sides of the other foldable area 120. The third supporting portions 150 are connected to the two opposite sides of the bottom 110. Each rib portion 170 includes a hole 171, and each rib portion 170 is connected to each third supporting portion 150. Each fourth supporting portion 160 includes a plurality of protruding portions 161, and each fourth supporting portion 160 is connected to each rib portion 170 such that the fourth supporting portions 160 and the third supporting portions 150 are respectively disposed at two opposite sides of each rib portion 170. Each handle 180 is connected to each second supporting portion 140.

[0024] Between each foldable area 120 and the bottom 110 is a first fold line FL1. Between one of the foldable areas 120 and each first supporting portion 130 is a second fold line FL2. Between the other foldable area 120 and each second supporting portion 140 is a third fold line FL3. Between each third supporting portion 150 and the bottom 110 is a fourth fold line FL4. Between each rib portion 170 and each third supporting portion 150 is a fifth fold line FL5. Between each fourth supporting portion 160 and each rib portion 170 is a sixth fold line FL6. Between each handle 180 and each second supporting portion 140 may be a seventh fold line FL7.

[0025] When the two-handle packaging structure 100 is folded along the two first fold lines FL1, the two second fold lines FL2, the two third fold lines FL3, the two fourth fold lines FL4, the two fifth fold lines FL5 and the two sixth fold lines FL6, each first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160. The protruding portions 161 of each fourth supporting portion 160 are correspondingly engaged with the fitting holes 111 of the bottom 110, and each handle 180 extends through the hole 171 of each rib portion 170.

[0026] The two-handle packaging structure 100 improves robustness by providing two first supporting portions 130, two second supporting portions 140, two third supporting portions 150 and two fourth supporting portions 160, thereby increasing the maximum loading capacity of the two-handle packaging structure 100.

[0027] Furthermore, by providing a plurality of fitting holes 111 and a plurality of protruding portions 161, the two-handle packaging structure 100 ensures that when the protruding portions 161 are correspondingly engaged with the fitting holes 111, the clamping relationship among the first supporting portions 130, the second supporting portions 140, the third supporting portions 150 and the fourth supporting portions 160 is secured, thereby enhancing the robustness of the two-handle packaging structure 100.

[0028] Specifically, each hole 171 may be located at the center of each rib portion 170, such that when each handle 180 extends through the corresponding hole 171, each handle 180 is positioned at the center of each rib portion 170. Thus, when a user grips the handle 180 to lift the two-handle packaging structure 100, the force can be applied more effectively, thereby facilitating extraction of the two-handle packaging structure 100.

[0029] Referring simultaneously to FIGS. 2 to 5, FIG. 2 illustrates a perspective schematic view of the folded two-handle packaging structure 100 of FIG. 1. FIG. 3 illustrates a partial schematic view of the bottom 110 of the two-handle packaging structure 100 of FIG. 2. FIG. 4 illustrates a partial schematic view of the rib portion 170 of the two-handle packaging structure 100 of FIG. 2. FIG. 5 illustrates another perspective schematic view of the folded two-handle packaging structure 100 of FIG. 1. The folding method and details of the two-handle packaging structure 100 of the present disclosure will be described below with reference to FIGS. 2 to 5 in conjunction with FIG. 1.

[0030] As shown in FIG. 2, the two-handle packaging structure 100 is folded along the two first fold lines FL1, such that the two foldable areas 120, the two first supporting portions 130 and the two second supporting portions 140 are perpendicular to the bottom 110. Next, the two-handle packaging structure 100 is first folded along the two second fold lines FL2 and then folded along the two third fold lines FL3, such that the two second supporting portions 140 are located outside the two first supporting portions 130. The two-handle packaging structure 100 is then folded along the two fourth fold lines FL4, the two fifth fold lines FL5 and the two sixth fold lines FL6 toward the folding direction X.

[0031] As shown in FIGS. 3 and 4, the protruding portions 161 of each fourth supporting portion 160 are inserted into the corresponding fitting holes 111 of the bottom 110, such that each first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160. The protruding portions 161 of each fourth supporting portion 160 are correspondingly engaged with the fitting holes 111 of the bottom 110, thereby fixing the clamping relationship among the first supporting portions 130, the second supporting portions 140, the third supporting portions 150 and the fourth supporting portions 160. It should be particularly noted that, in the structure shown in FIG. 5, although the third supporting portion 150, the second supporting portion 140, the first supporting portion 130 and the fourth supporting portion 160 are arranged sequentially, the positions of the second supporting portion 140 and the first supporting portion 130 may be interchanged. Therefore, the present disclosure is not limited to the arrangement order illustrated in FIG. 5.

[0032] Specifically, the shapes of the fitting holes 111 and the protruding portions 161 must correspond to each other to achieve mutual engagement by fitting, and the present disclosure is not limited to the shapes illustrated in the drawings.

[0033] As shown in FIG. 5, when the two-handle packaging structure 100 is fully assembled, each first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160. The protruding portions 161 of each fourth supporting portion 160 are correspondingly engaged with the fitting holes 111 of the bottom 110, and each handle 180 extends through the hole 171 of each rib portion 170.

[0034] Referring simultaneously to FIGS. 5, 6, and 7, FIG. 6 illustrates another unfolded schematic view of the two-handle packaging structure 100 according to an embodiment of the present disclosure. FIG. 7 illustrates a cross-sectional schematic view of the two-handle packaging structure 100 of FIG. 5 taken along section line 7-7. The dimensional relationships and details of the two-handle packaging structure 100 of the present disclosure will be described below with reference to FIGS. 5 to 7 in conjunction with FIG. 1. It should be particularly noted that the dimensional relationships described below may be combined and arranged arbitrarily to achieve the corresponding effects.

[0035] One of the two foldable areas 120 may have a first length L1, and the other of the two foldable areas 120 may have a second length L2. The bottom 110 may have a third length L3. Each rib portion 170 may have a fourth length L4. Each second supporting portion 140 may have a fifth length L5. Each handle 180 may have a sixth length L6. Each fitting hole 111 may have a first width W1. Each rib portion 170 may have a second width W2. The edge of each second supporting portion 140 connected to each handle 180 to the seventh fold line FL7 may have a third width W3.

[0036] In addition, the two-handle packaging structure 100 may have a thickness T, which satisfies the following condition: 0.5 mm ≤ T ≤ 8.0 mm. This allows the structure to meet packaging specification requirements for different products, thereby enhancing the application potential of the two-handle packaging structure 100 of the present disclosure in related industries.

[0037] The first length L1 may be greater than the second length L2, or the second length L2 may be greater than the first length L1. The first length L1 may equal to the third length L3 minus two times the first width W1, or the second length L2 may equal to the third length L3 minus two times the first width W1. The third length L3 may be greater than both the first length L1 and the second length L2. The first length L1 may equal to the second length L2 plus two times the thickness of the two-handle packaging structure 100, or the second length L2 may equal to the first length L1 plus two times the thickness of the two-handle packaging structure 100. Through the above dimensional relationships, after folding, the first supporting portions 130, the second supporting portions 140, the third supporting portions 150 and the fourth supporting portions 160 may be positioned more closely together, thereby favoring an increase in the maximum loading capacity of the two-handle packaging structure 100.

[0038] The first width W1 may be greater than or equal to two times the thickness of the two-handle packaging structure 100, and the second width W2 may be greater than or equal to three times the thickness of the two-handle packaging structure 100. Thus, after folding, the engagement between the protruding portions 161 and the fitting holes 111 becomes tighter, and the clamping of the first supporting portions 130 and the second supporting portions 140 by the third supporting portions 150 and the fourth supporting portions 160 becomes more secure.

[0039] The third width W3 may be greater than or equal to the thickness of the two-handle packaging structure 100. Thus, after folding, when each handle 180 extends through each hole 171, the handles 180 are not affected by the thickness of the two-handle packaging structure 100, thereby increasing the stability of the handles 180. Furthermore, when the two-handle packaging structure 100 is placed in a shipping box (not shown), the two handles 180 of the two-handle packaging structure 100 can be conveniently stored within the shipping box.

[0040] The fifth length L5 may be greater than or equal to 0.5 times the fourth length L4 plus 0.5 times the sixth length L6. Thus, after folding, when extracting the two-handle packaging structure 100, the stability of the two-handle packaging structure 100 can be further improved.

[0041] Furthermore, the actual dimensions of the third length L3 and the fourth length L4 may be adjusted according to the dimensions of the contents. For example, the third length L3 minus the widths (not labeled) of the fitting holes 111 on both sides and minus the width of the contents may be greater than or equal to the thickness of the two-handle packaging structure 100, and the fourth length L4 minus the length of the contents may be greater than or equal to the thickness of the two-handle packaging structure 100. Thus, an appropriate space can be retained between the contents and the two-handle packaging structure 100 to facilitate packing and unpacking of the contents. However, the present disclosure is not limited to the above dimensions.

[0042] In further detail, the first supporting portion 130 has a length LA1, which is the distance from the second fold line FL2 to the edge of the first supporting portion 130. The length LA1 of the first supporting portion 130 may be less than or equal to the fifth length L5.

[0043] Each foldable area 120 has a width WA1, which is the distance from each first fold line FL1 to the edge of each foldable area 120. The third supporting portion 150 has a width WA2, which is the distance from each fourth fold line FL4 to each fifth fold line FL5. The fourth supporting portion 160 has a width WA3, which is the distance from each sixth fold line FL6 to the edge of the fourth supporting portion 160.

[0044] The width WA1 of each foldable area 120 may be less than or equal to the width WA2 of the third supporting portion 150, with the difference being equal to the thickness of the two-handle packaging structure 100. The width WA3 of the fourth supporting portion 160 may equal the width WA2 of the third supporting portion 150 minus one time the thickness of the two-handle packaging structure 100. Thus, the clamping of the first supporting portions 130 and the second supporting portions 140 by the third supporting portions 150 and the fourth supporting portions 160 becomes more secure.

[0045] Furthermore, the width WA1 of each foldable area 120 may be adjusted according to the dimensions of the contents. For example, the width WA1 of each foldable area 120 minus the height of the contents may be greater than or equal to the thickness of the two-handle packaging structure 100. Thus, an appropriate space can be retained between the contents and the two-handle packaging structure 100 to facilitate packing and unpacking of the contents. However, the present disclosure is not limited to the above dimensions.

[0046] As shown in FIG. 7, when the first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160, the clamping order from the outside to the inside of the two-handle packaging structure 100 may sequentially be: the third supporting portion 150, the second supporting portion 140, the first supporting portion 130 and the fourth supporting portion 160.

[0047] Specifically, the clamping order among the first supporting portion 130, the second supporting portion 140, the third supporting portion 150 and the fourth supporting portion 160 is influenced by the first length L1 and the second length L2. For example, when the first length L1 is greater than the second length L2, the clamping order from the outside to the inside of the two-handle packaging structure 100 is: the third supporting portion 150, the first supporting portion 130, the second supporting portion 140 and the fourth supporting portion 160. When the second length L2 is greater than the first length L1, the clamping order from the outside to the inside of the two-handle packaging structure 100 is: the third supporting portion 150, the second supporting portion 140, the first supporting portion 130 and the fourth supporting portion 160.

[0048] In addition, the size of each hole 171 may be adjusted according to the fifth length L5 and the thickness of the two-handle packaging structure 100, such that each handle 180 can extend through each hole 171. Furthermore, each handle 180 may have a handle length (not labeled), which is the distance from the seventh fold line FL7 to the edge of each handle 180 farthest from the seventh fold line FL7. The handle length may be greater than or equal to 10 mm to provide sufficient handle strength and size. Each handle 180 may also have a gripping hole (not labeled), where the length of the gripping hole may be greater than or equal to 20 mm and the width may be greater than or equal to 10 mm, thereby facilitating a user to grasp the handle and lift it. However, the present disclosure is not limited thereto.

[0049] Referring to FIGS. 8 and 9, FIG. 8 illustrates an exploded schematic view of another embodiment of the two-handle packaging structure 200 of the present disclosure. The arrangement of the two-handle packaging structure 200 in FIG. 8 is similar to that of the two-handle packaging structure 100 in FIG. 1, and the similarities will not be described again herein. FIG. 9 illustrates a perspective schematic view of the folded two-handle packaging structure 200 of FIG. 8. The folding method of the two-handle packaging structure 200 in FIG. 9 is similar to that of the two-handle packaging structure 100 in FIG. 6, and the similarities will not be described again herein.

[0050] It is noteworthy that the two-handle packaging structure 200 may further include a cover 290. The cover 290 is connected to one of the two foldable areas 220, and an eighth fold line FL8 may be provided between the cover 290 and the one of the two foldable areas 220. Moreover, when the two-handle packaging structure 200 is folded in the same manner as the two-handle packaging structure 100 and is then folded along the eighth fold line FL8, the cover 290 may abut against the two rib portions 270 and the other one of the two foldable areas 220.

[0051] The cover 290 may include a top portion 291, a connecting portion 292, and two tabs 293. The top portion 291 may be connected to one of the two foldable areas 220, and the one of the two foldable areas 220 may be located between the top portion 291 and the bottom 210. The connecting portion 292 may be connected to the top portion 291 such that the top portion 291 is located between the one of the two foldable areas 220 and the connecting portion 292. The tabs 293 may be connected to two opposite sides of the connecting portion 292.

[0052] The eighth fold line FL8 may be located between the top portion 291 and one of the two foldable areas 220. A ninth fold line FL9 may be provided between the connecting portion 292 and the top portion 291, and a tenth fold line FL10 may be respectively provided between each tab 293 and the connecting portion 292.

[0053] Referring simultaneously to FIGS. 9 and 10, FIG. 10 illustrates another perspective schematic view of the folded two-handle packaging structure 200 of FIG. 8. The folding method and details of the two-handle packaging structure 200 of the present disclosure will be described below with reference to FIGS. 9 and 10 in conjunction with FIG. 8.

[0054] When the two-handle packaging structure 200 is folded in the same manner as the two-handle packaging structure 100 and is then folded along the eighth fold line FL8, the cover 290 may abut against the two rib portions 270 and the other one of the two foldable areas 220. When the two-handle packaging structure 200 is further folded along the ninth fold line FL9 and the two tenth fold lines FL10, the tabs 293 may be correspondingly inserted between the third supporting portions 250 and the fourth supporting portions 260.

[0055] Specifically, the top portion 291 may have a fourth width W4, and each rib portion 270 may have a fourth length L4a. The fourth width W4 may be greater than or equal to the sum of the fourth length L4a and the thickness of the two-handle packaging structure 100. Thus, after the two-handle packaging structure 100 is folded, the edge of the cover 290 may abut against the other one of the two foldable areas 220.

[0056] The connecting portion 292 may have a fifth width W5, and the other one of the two foldable areas 220 may have a sixth width W6. The fifth width W5 may be greater than or equal to the sixth width W6 plus 0.5 times the thickness of the two-handle packaging structure 100. Thus, when the cover 290 is folded along the eighth fold line FL8, the ninth fold line FL9 and the tenth fold line FL10, it is not affected by the thickness of the two-handle packaging structure 200, thereby meeting packaging specification requirements for different products and enhancing the application potential of the two-handle packaging structure 200 of the present disclosure in related industries.

[0057] In addition, when the first width W1a is greater than two times the thickness of the two-handle packaging structure 200, it facilitates the insertion of the tabs 293 between the third supporting portions 250 and the fourth supporting portions 260.

[0058] In summary, the two-handle packaging structure of the present disclosure improves structural robustness by providing the first supporting portions, the second supporting portions, the third supporting portions and the fourth supporting portions, thereby increasing the maximum loading capacity of the two-handle packaging structure. Furthermore, by providing a plurality of fitting holes and a plurality of protruding portions, when the protruding portions are correspondingly engaged with the fitting holes, the clamping relationship among the first supporting portions, the second supporting portions, the third supporting portions, and the fourth supporting portions is fixed, thereby further enhancing the robustness of the two-handle packaging structure.

[0059] Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.

[0060] It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims.

[0002] The present disclosure relates to a packaging structure, in particular to a two-handle packaging structure that is easy to assemble and has enhanced robustness.Description of Related Art

[0003] In conventional packaging structures, when packaging heavy objects, for the convenience of extraction by users, a plastic handle is often provided. However, the plastic handle is not integrally formed with the packaging structure, which not only consumes additional assembly time but also increases the use of plastic, failing to meet current environmental protection requirements.

[0004] In addition, during the delivery of goods, for protective purposes, conventional packaging structures are often further placed inside a shipping box. When the contents are heavy items, it is difficult to extract the packaging structure from the shipping box, and conventional packaging structures are often damaged due to insufficient structural robustness at the extraction points.

[0005] In view of the above, providing a two-handle packaging structure that is easy to assemble while maintaining robustness has become a goal pursued by related practitioners.SUMMARY

[0006] The objective of the present disclosure is to provide a two-handle packaging structure that is easy to assemble while also ensuring structural robustness.

The bottom includes a plurality of fitting holes, which are disposed at two opposite sides of the bottom. The foldable areas are connected to the other two opposite sides of the bottom, and each of the foldable areas and the bottom are respectively provided with a first fold line. The first supporting portions are connected to two opposite sides of one of the foldable areas, and between the one of the foldable areas and the first supporting portions are respectively provided with a second fold line. The second supporting portions are connected to two opposite sides of the other foldable area, and between the other foldable area and the second supporting portions are respectively provided with a third fold line.

[0022] Referring to FIG. 1, FIG. 1 illustrates an unfolded schematic view of a two-handle packaging structure 100 according to an embodiment of the present disclosure. The two-handle packaging structure 100 includes a bottom 110, two foldable areas 120, two first supporting portions 130, two second supporting portions 140, two third supporting portions 150, two fourth supporting portions 160, two rib portions 170 and two handles 180.

[0023] The bottom 110 includes a plurality of fitting holes 111, which are disposed at two opposite sides of the bottom 110. The foldable areas 120 are connected to the other two opposite sides of the bottom 110. The first supporting portions 130 are connected to two opposite sides of one of the foldable areas 120, and the second supporting portions 140 are connected to two opposite sides of the other foldable area 120. The third supporting portions 150 are connected to the two opposite sides of the bottom 110. Each rib portion 170 includes a hole 171, and each rib portion 170 is connected to each third supporting portion 150. Each fourth supporting portion 160 includes a plurality of protruding portions 161, and each fourth supporting portion 160 is connected to each rib portion 170 such that the fourth supporting portions 160 and the third supporting portions 150 are respectively disposed at two opposite sides of each rib portion 170. Each handle 180 is connected to each second supporting portion 140.

[0024] Between each foldable area 120 and the bottom 110 is a first fold line FL1. Between one of the foldable areas 120 and each first supporting portion 130 is a second fold line FL2. Between the other foldable area 120 and each second supporting portion 140 is a third fold line FL3. Between each third supporting portion 150 and the bottom 110 is a fourth fold line FL4. Between each rib portion 170 and each third supporting portion 150 is a fifth fold line FL5. Between each fourth supporting portion 160 and each rib portion 170 is a sixth fold line FL6. Between each handle 180 and each second supporting portion 140 may be a seventh fold line FL7.

[0025] When the two-handle packaging structure 100 is folded along the two first fold lines FL1, the two second fold lines FL2, the two third fold lines FL3, the two fourth fold lines FL4, the two fifth fold lines FL5 and the two sixth fold lines FL6, each first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160. The protruding portions 161 of each fourth supporting portion 160 are correspondingly engaged with the fitting holes 111 of the bottom 110, and each handle 180 extends through the hole 171 of each rib portion 170.

[0026] The two-handle packaging structure 100 improves robustness by providing two first supporting portions 130, two second supporting portions 140, two third supporting portions 150 and two fourth supporting portions 160, thereby increasing the maximum loading capacity of the two-handle packaging structure 100.

[0027] Furthermore, by providing a plurality of fitting holes 111 and a plurality of protruding portions 161, the two-handle packaging structure 100 ensures that when the protruding portions 161 are correspondingly engaged with the fitting holes 111, the clamping relationship among the first supporting portions 130, the second supporting portions 140, the third supporting portions 150 and the fourth supporting portions 160 is secured, thereby enhancing the robustness of the two-handle packaging structure 100.

[0028] Specifically, each hole 171 may be located at the center of each rib portion 170, such that when each handle 180 extends through the corresponding hole 171, each handle 180 is positioned at the center of each rib portion 170. Thus, when a user grips the handle 180 to lift the two-handle packaging structure 100, the force can be applied more effectively, thereby facilitating extraction of the two-handle packaging structure 100.

[0029] Referring simultaneously to FIGS. 2 to 5, FIG. 2 illustrates a perspective schematic view of the folded two-handle packaging structure 100 of FIG. 1. FIG. 3 illustrates a partial schematic view of the bottom 110 of the two-handle packaging structure 100 of FIG. 2. FIG. 4 illustrates a partial schematic view of the rib portion 170 of the two-handle packaging structure 100 of FIG. 2. FIG. 5 illustrates another perspective schematic view of the folded two-handle packaging structure 100 of FIG. 1. The folding method and details of the two-handle packaging structure 100 of the present disclosure will be described below with reference to FIGS. 2 to 5 in conjunction with FIG. 1.

[0030] As shown in FIG. 2, the two-handle packaging structure 100 is folded along the two first fold lines FL1, such that the two foldable areas 120, the two first supporting portions 130 and the two second supporting portions 140 are perpendicular to the bottom 110. Next, the two-handle packaging structure 100 is first folded along the two second fold lines FL2 and then folded along the two third fold lines FL3, such that the two second supporting portions 140 are located outside the two first supporting portions 130. The two-handle packaging structure 100 is then folded along the two fourth fold lines FL4, the two fifth fold lines FL5 and the two sixth fold lines FL6 toward the folding direction X.

[0031] As shown in FIGS. 3 and 4, the protruding portions 161 of each fourth supporting portion 160 are inserted into the corresponding fitting holes 111 of the bottom 110, such that each first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160. The protruding portions 161 of each fourth supporting portion 160 are correspondingly engaged with the fitting holes 111 of the bottom 110, thereby fixing the clamping relationship among the first supporting portions 130, the second supporting portions 140, the third supporting portions 150 and the fourth supporting portions 160. It should be particularly noted that, in the structure shown in FIG. 5, although the third supporting portion 150, the second supporting portion 140, the first supporting portion 130 and the fourth supporting portion 160 are arranged sequentially, the positions of the second supporting portion 140 and the first supporting portion 130 may be interchanged. Therefore, the present disclosure is not limited to the arrangement order illustrated in FIG. 5.

[0032] Specifically, the shapes of the fitting holes 111 and the protruding portions 161 must correspond to each other to achieve mutual engagement by fitting, and the present disclosure is not limited to the shapes illustrated in the drawings.

[0033] As shown in FIG. 5, when the two-handle packaging structure 100 is fully assembled, each first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160. The protruding portions 161 of each fourth supporting portion 160 are correspondingly engaged with the fitting holes 111 of the bottom 110, and each handle 180 extends through the hole 171 of each rib portion 170.

[0034] Referring simultaneously to FIGS. 5, 6, and 7, FIG. 6 illustrates another unfolded schematic view of the two-handle packaging structure 100 according to an embodiment of the present disclosure. FIG. 7 illustrates a cross-sectional schematic view of the two-handle packaging structure 100 of FIG. 5 taken along section line 7-7. The dimensional relationships and details of the two-handle packaging structure 100 of the present disclosure will be described below with reference to FIGS. 5 to 7 in conjunction with FIG. 1. It should be particularly noted that the dimensional relationships described below may be combined and arranged arbitrarily to achieve the corresponding effects.

[0035] One of the two foldable areas 120 may have a first length L1, and the other of the two foldable areas 120 may have a second length L2. The bottom 110 may have a third length L3. Each rib portion 170 may have a fourth length L4. Each second supporting portion 140 may have a fifth length L5. Each handle 180 may have a sixth length L6. Each fitting hole 111 may have a first width W1. Each rib portion 170 may have a second width W2. The edge of each second supporting portion 140 connected to each handle 180 to the seventh fold line FL7 may have a third width W3.

[0036] In addition, the two-handle packaging structure 100 may have a thickness T, which satisfies the following condition: 0.5 mm ≤ T ≤ 8.0 mm. This allows the structure to meet packaging specification requirements for different products, thereby enhancing the application potential of the two-handle packaging structure 100 of the present disclosure in related industries.

[0037] The first length L1 may be greater than the second length L2, or the second length L2 may be greater than the first length L1. The first length L1 may equal to the third length L3 minus two times the first width W1, or the second length L2 may equal to the third length L3 minus two times the first width W1. The third length L3 may be greater than both the first length L1 and the second length L2. The first length L1 may equal to the second length L2 plus two times the thickness of the two-handle packaging structure 100, or the second length L2 may equal to the first length L1 plus two times the thickness of the two-handle packaging structure 100. Through the above dimensional relationships, after folding, the first supporting portions 130, the second supporting portions 140, the third supporting portions 150 and the fourth supporting portions 160 may be positioned more closely together, thereby favoring an increase in the maximum loading capacity of the two-handle packaging structure 100.

[0038] The first width W1 may be greater than or equal to two times the thickness of the two-handle packaging structure 100, and the second width W2 may be greater than or equal to three times the thickness of the two-handle packaging structure 100. Thus, after folding, the engagement between the protruding portions 161 and the fitting holes 111 becomes tighter, and the clamping of the first supporting portions 130 and the second supporting portions 140 by the third supporting portions 150 and the fourth supporting portions 160 becomes more secure.

[0039] The third width W3 may be greater than or equal to the thickness of the two-handle packaging structure 100. Thus, after folding, when each handle 180 extends through each hole 171, the handles 180 are not affected by the thickness of the two-handle packaging structure 100, thereby increasing the stability of the handles 180. Furthermore, when the two-handle packaging structure 100 is placed in a shipping box (not shown), the two handles 180 of the two-handle packaging structure 100 can be conveniently stored within the shipping box.

[0040] The fifth length L5 may be greater than or equal to 0.5 times the fourth length L4 plus 0.5 times the sixth length L6. Thus, after folding, when extracting the two-handle packaging structure 100, the stability of the two-handle packaging structure 100 can be further improved.

[0041] Furthermore, the actual dimensions of the third length L3 and the fourth length L4 may be adjusted according to the dimensions of the contents. For example, the third length L3 minus the widths (not labeled) of the fitting holes 111 on both sides and minus the width of the contents may be greater than or equal to the thickness of the two-handle packaging structure 100, and the fourth length L4 minus the length of the contents may be greater than or equal to the thickness of the two-handle packaging structure 100. Thus, an appropriate space can be retained between the contents and the two-handle packaging structure 100 to facilitate packing and unpacking of the contents. However, the present disclosure is not limited to the above dimensions.

[0042] In further detail, the first supporting portion 130 has a length LA1, which is the distance from the second fold line FL2 to the edge of the first supporting portion 130. The length LA1 of the first supporting portion 130 may be less than or equal to the fifth length L5.

[0043] Each foldable area 120 has a width WA1, which is the distance from each first fold line FL1 to the edge of each foldable area 120. The third supporting portion 150 has a width WA2, which is the distance from each fourth fold line FL4 to each fifth fold line FL5. The fourth supporting portion 160 has a width WA3, which is the distance from each sixth fold line FL6 to the edge of the fourth supporting portion 160.

[0044] The width WA1 of each foldable area 120 may be less than or equal to the width WA2 of the third supporting portion 150, with the difference being equal to the thickness of the two-handle packaging structure 100. The width WA3 of the fourth supporting portion 160 may equal the width WA2 of the third supporting portion 150 minus one time the thickness of the two-handle packaging structure 100. Thus, the clamping of the first supporting portions 130 and the second supporting portions 140 by the third supporting portions 150 and the fourth supporting portions 160 becomes more secure.

[0045] Furthermore, the width WA1 of each foldable area 120 may be adjusted according to the dimensions of the contents. For example, the width WA1 of each foldable area 120 minus the height of the contents may be greater than or equal to the thickness of the two-handle packaging structure 100. Thus, an appropriate space can be retained between the contents and the two-handle packaging structure 100 to facilitate packing and unpacking of the contents. However, the present disclosure is not limited to the above dimensions.

[0046] As shown in FIG. 7, when the first supporting portion 130 and each second supporting portion 140 are clamped by the corresponding third supporting portions 150 and the corresponding fourth supporting portions 160, the clamping order from the outside to the inside of the two-handle packaging structure 100 may sequentially be: the third supporting portion 150, the second supporting portion 140, the first supporting portion 130 and the fourth supporting portion 160.

[0047] Specifically, the clamping order among the first supporting portion 130, the second supporting portion 140, the third supporting portion 150 and the fourth supporting portion 160 is influenced by the first length L1 and the second length L2. For example, when the first length L1 is greater than the second length L2, the clamping order from the outside to the inside of the two-handle packaging structure 100 is: the third supporting portion 150, the first supporting portion 130, the second supporting portion 140 and the fourth supporting portion 160. When the second length L2 is greater than the first length L1, the clamping order from the outside to the inside of the two-handle packaging structure 100 is: the third supporting portion 150, the second supporting portion 140, the first supporting portion 130 and the fourth supporting portion 160.

[0048] In addition, the size of each hole 171 may be adjusted according to the fifth length L5 and the thickness of the two-handle packaging structure 100, such that each handle 180 can extend through each hole 171. Furthermore, each handle 180 may have a handle length (not labeled), which is the distance from the seventh fold line FL7 to the edge of each handle 180 farthest from the seventh fold line FL7. The handle length may be greater than or equal to 10 mm to provide sufficient handle strength and size. Each handle 180 may also have a gripping hole (not labeled), where the length of the gripping hole may be greater than or equal to 20 mm and the width may be greater than or equal to 10 mm, thereby facilitating a user to grasp the handle and lift it. However, the present disclosure is not limited thereto.

[0049] Referring to FIGS. 8 and 9, FIG. 8 illustrates an exploded schematic view of another embodiment of the two-handle packaging structure 200 of the present disclosure. The arrangement of the two-handle packaging structure 200 in FIG. 8 is similar to that of the two-handle packaging structure 100 in FIG. 1, and the similarities will not be described again herein. FIG. 9 illustrates a perspective schematic view of the folded two-handle packaging structure 200 of FIG. 8. The folding method of the two-handle packaging structure 200 in FIG. 9 is similar to that of the two-handle packaging structure 100 in FIG. 6, and the similarities will not be described again herein.

[0050] It is noteworthy that the two-handle packaging structure 200 may further include a cover 290. The cover 290 is connected to one of the two foldable areas 220, and an eighth fold line FL8 may be provided between the cover 290 and the one of the two foldable areas 220. Moreover, when the two-handle packaging structure 200 is folded in the same manner as the two-handle packaging structure 100 and is then folded along the eighth fold line FL8, the cover 290 may abut against the two rib portions 270 and the other one of the two foldable areas 220.

[0051] The cover 290 may include a top portion 291, a connecting portion 292, and two tabs 293. The top portion 291 may be connected to one of the two foldable areas 220, and the one of the two foldable areas 220 may be located between the top portion 291 and the bottom 210. The connecting portion 292 may be connected to the top portion 291 such that the top portion 291 is located between the one of the two foldable areas 220 and the connecting portion 292. The tabs 293 may be connected to two opposite sides of the connecting portion 292.

[0052] The eighth fold line FL8 may be located between the top portion 291 and one of the two foldable areas 220. A ninth fold line FL9 may be provided between the connecting portion 292 and the top portion 291, and a tenth fold line FL10 may be respectively provided between each tab 293 and the connecting portion 292.

[0053] Referring simultaneously to FIGS. 9 and 10, FIG. 10 illustrates another perspective schematic view of the folded two-handle packaging structure 200 of FIG. 8. The folding method and details of the two-handle packaging structure 200 of the present disclosure will be described below with reference to FIGS. 9 and 10 in conjunction with FIG. 8.

[0054] When the two-handle packaging structure 200 is folded in the same manner as the two-handle packaging structure 100 and is then folded along the eighth fold line FL8, the cover 290 may abut against the two rib portions 270 and the other one of the two foldable areas 220. When the two-handle packaging structure 200 is further folded along the ninth fold line FL9 and the two tenth fold lines FL10, the tabs 293 may be correspondingly inserted between the third supporting portions 250 and the fourth supporting portions 260.

[0055] Specifically, the top portion 291 may have a fourth width W4, and each rib portion 270 may have a fourth length L4a. The fourth width W4 may be greater than or equal to the sum of the fourth length L4a and the thickness of the two-handle packaging structure 100. Thus, after the two-handle packaging structure 100 is folded, the edge of the cover 290 may abut against the other one of the two foldable areas 220.

[0056] The connecting portion 292 may have a fifth width W5, and the other one of the two foldable areas 220 may have a sixth width W6. The fifth width W5 may be greater than or equal to the sixth width W6 plus 0.5 times the thickness of the two-handle packaging structure 100. Thus, when the cover 290 is folded along the eighth fold line FL8, the ninth fold line FL9 and the tenth fold line FL10, it is not affected by the thickness of the two-handle packaging structure 200, thereby meeting packaging specification requirements for different products and enhancing the application potential of the two-handle packaging structure 200 of the present disclosure in related industries.

[0057] In addition, when the first width W1a is greater than two times the thickness of the two-handle packaging structure 200, it facilitates the insertion of the tabs 293 between the third supporting portions 250 and the fourth supporting portions 260.

[0058] In summary, the two-handle packaging structure of the present disclosure improves structural robustness by providing the first supporting portions, the second supporting portions, the third supporting portions and the fourth supporting portions, thereby increasing the maximum loading capacity of the two-handle packaging structure. Furthermore, by providing a plurality of fitting holes and a plurality of protruding portions, when the protruding portions are correspondingly engaged with the fitting holes, the clamping relationship among the first supporting portions, the second supporting portions, the third supporting portions, and the fourth supporting portions is fixed, thereby further enhancing the robustness of the two-handle packaging structure.

[0059] Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.

[0060] It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims.
