BACKGROUND

Technical Field

The present disclosure relates to a buffer packaging structure and a packing box structure. More particularly, the present disclosure relates to a buffer packaging structure and a packing box structure that are convenient to use and can effectively position a target object.

Description of Related Art

The packaging materials of the product not only serve as the function of protection during transportation, but also help improve marketing and increase sales. In view of rising awareness of environmental protection, the use of plastic-free packaging materials made of non-plastic materials has gradually become the mainstream of related industries.

To address the above-mentioned problems, the buffer packaging materials made of paper-based materials have gradually applied to the product packaging to reduce the environmental impact of waste plastic packaging materials. However, the paper-based materials have a certain thickness specification, and thus the gap between the target object and the outer box cannot be completely filled or fitted by directly applying the commercially paper-based materials to the product packaging. Accordingly, a space between the target object and the outer box still exists, resulting in the risk of damaging the target object due to shaking and handling process.

In view of this, the development of a buffer packaging structure that meets the environmental protection and commercial demands, and can effectively position the target object has become the goal of research by related industry.

In the packing box structure 200, the box 10 can be the box 10 of FIG. 2, so that the details thereof are described in FIG. 2, and it will not be described again herein.

The at least one buffer packaging structure 100 can be detachably disposed in the accommodating space 11, and the at least one buffer packaging structure 100 is disposed between at least one target object 20 and the box 10.

In the packing box structure 200, the buffer packaging structure 100 can be the buffer packaging structure 100 of FIG. 1, so that the details thereof are described in FIG. 1, and it will not be described again herein. A number of the buffer packaging structure 100 is two, and the two buffer packaging structures 100 can be detachably disposed in the accommodating space 11 and respectively correspond to two sides of the target object 20. Because the base plate 110 and the lower plate 120 of the buffer packaging structure 100 are relatively bent towards each other along the first foldable area 101, the base plate 110 and the lower plate 120 are substantially vertical to each other, so that the buffer packaging structure 100 is substantially L-shaped in appearance. At the same time, the lower plate 120 of each of the buffer packaging structures 100 is inserted between the target object 20 and the box 10, and the base plate 110 is disposed between the target object 20 and an upper cover 12 of the box 10 when the box 10 is completely sealed so as to provide a buffering effect from another direction. Therefore, the buffer packaging structure 100 can stably position the target object 20 in the box 10, so that the damages of the target object 20 due to shaking and handling process can be avoided.

Further, when the target object 20 is to be taken out from the box 10, the user can adjust the base plate 110 to bend along the first foldable area 101 towards a direction opposite the lower plate 120. At this time, two surfaces (reference number is omitted) of the base plate 110 are not be covered by other elements and can be held and pulled by the user, and the lower plate 120 is removed from the gap between the target object 20 and the box 10 along with the displacement of the base plate 110. Thus, an operation space for the user to take out the target object 20 from the box 10 can be obtained, so that picking up and placing the target object 20 is easier.

Therefore, by the arrangement that the packing box structure 200 of the present disclosure includes the buffer packaging structure 100, the base plate 110 and the lower plate 120 of the buffer packaging structure 100 are relatively bent towards each other along the first foldable area 101, and proper size ratios of the base plate 110, the lower plate 120 and the accommodating space 11 are satisfied. The buffer packaging structure 100 can effectively inserted into the gap between the target object 20 and the box 10, and thus the target object 20 can be positioned in the box 10, so that the damages of the target object due to shaking and handling process can be avoided.

The buffer packaging structure 300 is applied in the accommodating space 11 and configured to insert and fill the gap between the target object (not shown in the figure) and the box 10, so that the damages of the target object due to shaking and handling process can be avoided. The buffer packaging structure 300 includes a base plate 310, a lower plate 320, a first foldable area 301, a first side plate 330, a first connecting plate 340, a second side plate 350, a second connecting plate 360 and at least two second foldable areas 302.

The base plate 310 has a connecting side 311 and two opposite sides 312, wherein the connecting side 311 is connected with the two opposite sides 312, and the two opposite sides 312 are opposite each other.

Specifically, when the two lower side sheets 324 are respectively bent along the two foldable lines 325 towards the first portion 322, as shown in FIG. 5, the two lower side sheets 324 are respectively connected with the lower plate mainbody 321 with a manner of one side thereof being free. When the buffer packaging structure 300 is inserted into the gap between the target object and the box 10, the two lower side sheets 324 will respectively abut against the target object or the box 10 so as to buffer an external force during transportation, and an excellent protection and positioning effect can be obtained.

The first foldable area 301 is disposed on the base plate 310, wherein the base plate 310 and the lower plate 320 are configured to relatively bend towards each other along the first foldable area 301, and thus the base plate 310 and the lower plate 320 are substantially vertical to each other. As shown in FIG. 5, when the base plate 310 and the lower plate 320 are bent towards each other along the first foldable area 301, the buffer packaging structure 300 is substantially L-shaped in appearance, and the buffering and positioning effects from different directions to the target object can be obtained.

The first side plate 330 is connected with the base plate 310, wherein the first side plate 330 has a first free side 331, and the first free side 331 is disposed on one side of the first side plate 330 away from the base plate 310. When a maximum length of the base plate 310 is A3, and a length of the first free side 331 is D2, the following condition can be satisfied: D2≤A3. Hence, by the arrangement that the length D2 of the first free side 331 of the first side plate 330 is smaller than or equal to the maximum length A3 of the base plate 310, it is favorable for preventing the buffer packaging structure 300 from abutting against the overlapping plates (not shown in the figure) on a corner of the accommodating space 11 of the box 10. Therefore, it is favorable for picking up and placing the buffer packaging structure 300, and the effect of the buffer packaging structure 300 configured to position the target object can be enhanced.

The first connecting plate 340 is connected with the first side plate 330, wherein the first side plate 330 is connected with one of the two opposite sides 312 of the base plate 310 through the first connecting plate 340.

The second side plate 350 is connected with the base plate 310, wherein the second side plate 350 has a second free side 351, and the second free side 351 is disposed on one side of the second side plate 350 away from the base plate 310. When the maximum length of the base plate 310 is A3, and a length of the second free side 351 is D5, the following condition can be satisfied: D5≤A3. Therefore, by the arrangement that the maximum length D5 of the second free side 351 of the second side plate 350 is smaller than or equal to the maximum length A3 of the base plate 310, it is favorable for preventing the buffer packaging structure 300 from abutting against the overlapping plates on the corner of the accommodating space 11 of the box 10. Therefore, it is favorable for picking up and placing the buffer packaging structure 300, and the effect of the buffer packaging structure 300 configured to position the target object can be enhanced.

The second connecting plate 360 is connected with the second side plate 350, wherein the second side plate 350 is connected with another one of the two opposite sides 312 of the base plate 310 through the second connecting plate 360.

The at least two second foldable areas 302 are respectively disposed on the first connecting plate 340 and the second connecting plate 360. The first side plate 330 and the second side plate 350 are configured to relatively bend towards each other along the at least two second foldable areas 302. In detail, in the buffer packaging structure 300, each of the at least two second foldable areas 302 can include at least one foldable line (reference number is omitted). Take the at least two second foldable areas 302 disposed on the first connecting plate 340 as an example, the at least one foldable line of the second foldable area 302 can be disposed on at least one of one side of the first connecting plate 340 close to the base plate 310 and one side of the first connecting plate 340 close to the first side plate 330, and thus the first side plate 330 can bend along the at least two second foldable areas 302 and simultaneously drive the first connecting plate 340 to bend towards the base plate 310, but the present disclosure is not limited thereto.

The accommodating space 11 has the inner length B1, the inner width B2 and the inner height B3, and when a maximum width of the lower plate 320 is A1, a maximum width of the base plate 310 is A2, a maximum length of the base plate 310 is A3, and a maximum length of the lower plate 320 is A4, the following conditions can be satisfied: A1≤A2; A2≤B2; A3≤B1; and A4≤B3. By satisfying the above conditions, the lower plate 320 of the buffer packaging structure 300 can be smoothly inserted into the gap between target object and the box 10, so that the damages of the target object in the accommodating space 11 due to shaking and handling process can be avoided.

When the maximum width of the lower plate 320 is A1, a width of the first portion 322 is A11, a length of the first portion 322 is A41, a length of the second portion 323 is A42, a width of the lower side sheets 324 is C1, and the accommodating space 11 has the inner height B3, the following conditions can be satisfied: A11≤A1; A41≤B3/2; A42≤B3; and C1≤A11/2. Therefore, proper ratios among the size of the first portion 322 of the lower plate 320, the size of the second portion 323 of the lower plate 320, and the size of the box 10 can be obtained, and thus the lower plate 320 can provide excellent buffering effect. Further, when the proper ratios between the size of the first portion 322 of the lower plate 320 and the size of the two lower side sheets 324 are satisfied, the impact of the buffering effect, which is generated from the two lower side sheets 324 bent towards the first portion 322 and then abutted against or stacked with each other, can be avoided.

As shown in FIG. 4 and FIG. 5, when the first side plate 330 and the second side plate 350 are relatively bent towards each other along the at least two second foldable areas 302 and then the second side plate 350 is stacked on the first side plate 330, a first frame 303 is formed by the base plate 310, the first side plate 330 and the second side plate 350. By the arrangement that the first frame 303 is formed by the base plate 310, the first side plate 330 and the second side plate 350, when an external force is applied on the buffer packaging structure 300, the first frame 303 can be reciprocating deformed to respond the external force, so that the external force can be buffered and the probability of the damage of the target object can be reduced. Further, the first frame 303 can provide a space on the buffer packaging structure 300 for placing the accessories such as instructions, so that the application range of the buffer packaging structure 300 is more extensive.

Therefore, by satisfying the above conditions, proper size ratios of the base plate 310, the first side plate 330, the first connecting plate 340, the second side plate 350 and the second connecting plate 360 can be obtained, and thus the first frame 303 having a stable structure can be obtained by relatively bending the base plate 310, the first side plate 330 and the second side plate 350. Therefore, the gap between the target object and the box 10 can be effectively filled so as to enhance the use of the efficiency of the buffer packaging structure 300 of the present disclosure.

The at least one inserted element 381 is disposed on one of the first side plate 330 and the second side plate 350, and the at least one slot 382 is disposed on one of the base plate 310, the first side plate 330 and the second side plate 350. As shown in FIG. 5, when the first side plate 330 and the second side plate 350 are relatively bent towards each other, and then the second side plate 350 is stacked on the first side plate 330 so as to form the first frame 303, the at least one inserted element 381 is correspondingly inserted into the at least one slot 382, so that it is favorable for preventing the first side plate 330 and the second side plate 350 from being unfolded, and the structure stability of the first frame 303 can be further enhanced.

Further, the second side plate 350 can further include at least one clip element 383 and at least one hole 384, and the at least one clip element 383 is correspondingly covered the at least one hole 384. Specifically, the at least one clip element 383 and the at least one hole 384 can be formed by the cutting process on the second side plate 350, wherein the at least one hole 384 has a convex arc area 385, and the user can prop up the at least one clip element 383 by entering the tip of the finger thereof into the convex arc area 385. At the same time, a card or a thin accessory can be placed between the clip element 383 and the hole 384, then the finger can be pulled away, and the card or the thin accessory can be positioned on the second side plate 350. Therefore, the applied extension of the buffer packaging structure 300 can be enhanced. Furthermore, in the buffer packaging structure 300, a number of the at least one clip element 383 can be four, a number of the at least one hole 384 also can be four, but the present disclosure is not limited thereto.

Therefore, it is favorable for picking up and placing the buffer packaging structure 300, but the present disclosure is not limited thereto. Moreover, a material of the base plate 310 and a material of the lower plate 320 can include natural fibers such as cellulose and lignin, or other materials with toughness, but the material are not limited thereto.
