Description

Technical Field

[0001] The utility model belongs to the technical field of packing boxes, and particularly relates to an inner support structure for packing. Background Art

[0002] Packing boxes are generally used for product packaging and play a very good role in protecting products during transportation and other processes. For some precision products, or products with relatively large volume and weight, when they are loaded into the packing box, an inner lining will be wrapped outside the product, and the inner lining plays a role in supporting and buffering the product.

[0003] In the existing packaging field, foam or foam cotton is generally used as the inner lining to wrap and support the product. However, foam and foam cotton are non-degradable materials and belong to white garbage. Excessive use will cause problems such as environmental pollution. To solve the defect of environmental pollution, for example, the Chinese patent document with the publication number CN221025299U discloses an inner lining for a packing box, including: a support member, a first limiting member, and a second limiting member, all of which are made of paper; wherein, the first limiting member and the second limiting member are respectively arranged at the first end and the opposite second end of the support member; the first limiting member includes an integral first body and at least two first limiting parts, the first body abuts against the bottom of the support member along its height direction, and at least two first limiting parts are respectively abutted against the first end of the support member and the outer side wall adjacent to the first end after being folded along the folding line between the first body, and any two adjacent first limiting parts abut against each other; the second limiting member includes an integral second body and at least two second limiting parts, the second body abuts against the bottom of the support member along its height direction, and at least two second limiting parts are respectively abutted against the second end of the support member and the outer side wall adjacent to the second end after being folded along the folding line between the second body, and any two adjacent second limiting parts abut against each other. The support member includes multiple layers of cardboard stacked together from top to bottom, and along the stacking direction, an opening is formed in a part of the cardboard at the top or bottom, a flanging is formed on one side wall of the opening, and an insertion interface communicating with the opening is formed in another part of the cardboard, and the flanging is inserted into the insertion interface. The inner lining can be selected from corrugated kraft paper or honeycomb kraft paper, etc.

[0004] In the technical solution disclosed in the above patent document, the inner lining is made of corrugated kraft paper or honeycomb kraft paper. When directly using corrugated paper or honeycomb paper to make the inner lining, due to the multi-honeycomb hole structure of the corrugated structure and the honeycomb structure, the side walls of the honeycomb holes are exposed. When they are mutually attached, the contact area of the honeycomb paper is small, so the bonding strength is insufficient, and it is easy to cause cracking and even falling off after being stressed. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an inner support structure for packaging, which is used to solve the problem in the prior art that when directly using honeycomb paperboard to make the inner lining, after the bottom plate and the side plates of the inner lining are bonded, due to the small bonding contact area, the force is likely to cause cracking.

[0006] To achieve the above object, an inner support structure for packaging provided by an embodiment of the present utility model is used to support and fix the goods in the packaging box, and includes a bottom plate, side plates and an outer skin; the bottom plate and the four side plates enclose a shell, the outer skin is attached to the outside of the shell, and the outer skin includes a reverse-folded attachment part that wraps around the inside of the corresponding side plate; the bottom plate, the side plates and the outer skin are all made of degradable materials.

[0007] Furthermore, the materials of the bottom plate and the side plates are honeycomb paperboard or cotton and linen blocks, and the material of the outer skin is paper or cotton and linen cloth.

[0008] Furthermore, the inner side wall of the side plate is attached to the outer side wall of the bottom plate.

[0009] Furthermore, the reverse-folded attachment part includes two first folded parts and two second folded parts. The two first folded parts wrap around the inside of the two relatively arranged side plates, and the two second folded parts wrap around the inside of the other two side plates; the top sides of the adjacent first folded part and the second folded part overlap and are fixedly attached.

[0010] Furthermore, clearance cuts are provided on both sides of the first folded part, so that the first folded part can be turned over and attached to the inside of the side plate; the clearance cuts form an attachment part on the top side of the first folded part, and the attachment part overlaps on the top side of the second folded part.

[0011] Furthermore, the top side of the side plate attached to the second folded part is lower than the top sides of the other two side plates.

[0012] Furthermore, a reinforcing plate is also attached to the top side of the bottom plate.

[0013] Furthermore, a plurality of through holes or counterbores are provided at the bottom of the shell.

[0014] Furthermore, the outer skin is adhesively bonded or stapled to the shell, or the outer skin is folded and fixed.

[0015] At least the following technical effects are achieved by one or more of the above technical solutions in the inner support structure for packaging provided by the embodiment of the present utility model:

[0016] The inner support structure of the present utility model is a shell structure formed by a bottom plate and side plates made of biodegradable materials. An outer skin is pasted on the outer side of the shell, and the outer skin is provided with a folded and attached portion that fits to the inner side surface of the side plates. Therefore, the shell is completely wrapped by the outer skin, thereby increasing the bonding strength between the side plates and the bottom plate of the shell, and enabling it to withstand greater supporting force without cracking.

[0026] In an embodiment of the translation door driving mechanism of the present utility model, please refer to Figures 1 to 4 . The inner support structure 20 of the package is provided in the inner lining of the packing box to support and buffer the packaged object. Specifically, the inner support structure of the package includes a bottom plate 100, side plates 200 and an outer skin 300. The bottom plate 100 and four groups of side plates 200 enclose a housing 1. The outer skin 300 can be fixed to the outside of the housing 1 by means of gluing or nailing. Moreover, the outer skin 300 includes a folded and adhered portion that wraps around the inner side of the corresponding side plate 200. The folded and adhered portion is fixed to the inner side wall of the housing 1 by means of gluing or nailing, and can also be fixed by folding the edge of the outer skin 300. So that the housing 1 is wrapped by the outer skin 300. Among them, the bottom plate 100, the side plates 200 and the outer skin 300 are all made of degradable materials. Therefore, it will not cause pollution to the environment. Specifically, the inner support structure of the package in this embodiment is a housing 1 structure completed by the bottom plate 100 and side plates 200 made of degradable materials. By providing a layer of outer skin 300 on the outside of the housing 1, and the outer skin 300 is provided with a folded and adhered portion that fits to the inner side surface of the side plate 200. Therefore, the housing 1 is completely wrapped by the outer skin 300, thereby increasing the bonding strength between the side plate 200 and the bottom plate 100 of the housing 1, and being able to withstand greater supporting force without cracking.

[0027] More specifically, the materials of the bottom plate 100 and the side plates 200 are honeycomb paperboard or cotton and linen blocks, and the material of the outer skin 300 is paper skin or cotton and linen cloth. Therefore, the inner support structure of the package can be recycled and reused, realizing environmental protection and multiple uses.

[0028] Further, please refer to Figures 1 to 4, the inner sidewall of the side plate 200 is adhesively bonded to the outer sidewall of the bottom plate 100. Therefore, when the outer skin 300 is wrapped around the outside of the housing 1, the side plate 200 can be pressed tightly around the bottom plate 100, which can increase the strength of the combination of the side plate 200 and the side plate 100.

[0029] Further, please refer to Figure 1 , Figure 2 Combined Figure 4 , the folding and fitting part includes two first folding parts 301 and two second folding parts 302. The two first folding parts 301 are wrapped inside two sets of oppositely arranged side plates 200, and the two second folding parts 302 are wrapped inside the other two sets of side plates 200. The top sides of the adjacent first folding part 301 and the second folding part 302 overlap each other and are fixed by gluing, nailing or folding each other. Thereby increasing the bonding strength of the adjacent two sets of side plates 200 and avoiding the problem of loosening under force.

[0030] Further, refer to Figure 1 And Figure 4 , clearance cutouts 303 are provided on both sides of the first folding part 301, so that the first folding part 301 can be folded and fitted to the inside of the side plate 200; the clearance cutouts 303 form a fitting part 304 on the top side of the first folding part 301, and the fitting part 304 overlaps on the top side of the second folding part 302.

[0031] Still further, refer to Figure 3 , the top side of the side plate 200 that fits with the second folding part 302 is lower than the top sides of the other two side plates 200. Therefore, when the second folding part 302 is fitted to the side plate 200, the top side of the second folding part 302 can be flush with the top sides of the other two side plates 200. Therefore, the fitting part 304 of the first folding part 301 can be flatly fitted on the top side of the second folding part 302.

[0032] Further, refer to Figure 2 , a reinforcing plate 400 is also fitted on the top side of the bottom plate 100. By providing the reinforcing plate 400 on the top side of the bottom plate 100 (the bottom of the housing 1), when the packaged object is supported inside the housing 1, it is the reinforcing plate 400 that contacts the packaged object. Through the support of the reinforcing plate 400, the stress area of the bottom plate 100 can be increased, and the problem of the bottom plate 100 being concave or collapsed due to local stress can be avoided.

[0033] Further, refer to Figure 1 And Figure 2 , a plurality of through holes 10 or counterbores are also provided at the bottom of the housing 1. Thereby, the protrusions on the packaged object can be cleared, and the problem of the bottom of the housing 1 being damaged by the sharp parts can be avoided.

[0034] Still further, please refer to Figure 1, An application of the inner support structure of the above embodiment. Specifically, two sets of inner support structures of the package form a lining structure, and the two sets of inner support structures are respectively arranged on both sides of the supported object to play a role in supporting both sides of the supported object.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
