BRIEF DESCRIPTION OF DRAWINGS

[0021] The meanings of the reference signs in the drawings are as follows.

[0022] 1 paper core body 2 upper hard paperboard layer

[0023] 3 lower hard paperboard layer 4 upper non-woven fabric layer

[0027] 11 buffer cavity DETAILED DESCRIPTION

[0028] The specific embodiments of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but are not used to limit the scope of the utility model.

[0029] As Figure 1 The composite paperboard structure suitable for gift packaging boxes comprises a paper core body 1, which is different in that in order to have appropriate compression resistance and deformation resistance effect after the packaging box is formed, facilitate stacking and placement needs, and effectively protect the contents, a bearing layer is pasted on the upper and lower end faces of the paper core body 1, which comprises an upper hard paperboard layer 2 pasted on the upper end face of the paper core body 1 and a lower hard paperboard layer 3 pasted on the lower end face of the paper core body 1. At the same time, an upper non-woven fabric layer 4 is pasted on the upper end face of the upper hard paperboard layer 2, and a lower non-woven fabric layer 5 is pasted on the lower end face of the lower hard paperboard layer 3. In this way, the stress pulling resistance of the entire paperboard is improved, and the possibility of tearing is reduced when it is improperly torn. Thus, a composite sandwich structure is formed, the deformation resistance of the entire paperboard is improved, and better integrity is achieved after the subsequent cutting processing into a paper box. Furthermore, a waterproof layer 6 is pasted on the upper end face of the upper non-woven fabric layer 4 to satisfy the appropriate waterproof effect and avoid water stains from invading from the surface of the paper box. In addition, according to the actual placement needs of the gift, an inner lining layer 7 is pasted on the lower end face of the lower non-woven fabric layer 5. In this way, after the packaging box is formed, the gift is placed in close contact with the inner lining layer 7.

[0030] In combination with a preferred embodiment of the utility model, the paper core body 1 comprises a bearing core 9 with a concave-convex structure in a pile opening shape, and the concave-convex structure is filled and distributed with buffer glue 10. In this way, the buffer glue 10 can absorb improper external stress impact, avoid abnormal deformation of the subsequently formed paper packaging box, reduce the abnormal state of concave, and will not press the gift as the contents. During manufacturing, the buffer glue 10 is a silica gel layer, and the buffer glue 10 is provided with a plurality of buffer cavities 11. Thus, the silica gel layer can be given a better moderate deformation space, and the buffer cavities 11 are used to absorb impact stress. Of course, other materials of glue can also be used to form the silica gel layer, which is adjusted according to the deformation resistance needs of the contents and the whole.

[0031] Further, the upper non-woven fabric layer 4 and the lower non-woven fabric layer 5 are spunlaced non-woven fabrics. In this way, stress transmission corresponding to the distribution direction can be realized by relying on the mesh texture of the spunlaced non-woven fabric, avoiding concentrated stress at a certain point, and improving the tearing resistance. At the same time, the non-woven fabric is relatively thin, and does not excessively increase the thickness of the paperboard structure.

[0032] In combination with the actual implementation, the thickness of the upper hard paperboard layer 2 and the lower hard paperboard layer 3 is 1 to 3 mm. Generally, 1.5 mm can be preferred. In this way, the thickness is not excessively increased during the appropriate hard support. The actual paperboard type of the upper hard paperboard layer 2 and the lower hard paperboard layer 3 can be adjusted according to the size of the finally formed paper gift box. Generally, copper plate paper with a suitable thickness can be selected. For some special anti-deformation support needs, corrugated paper can also be used.

[0033] At the same time, in order to have a suitable waterproof barrier effect, the waterproof layer 6 is a PC film layer or a PVC film layer. Relying on the film structure, the waterproof layer 6 can meet the waterproof requirement without affecting the subsequent cutting, forming and folding of the paperboard. Of course, a hydrophobic coating can also be used to form the waterproof layer 6 to avoid water stains on the surface and improve the waterproof effect.

[0034] Further, in order to have appropriate decoration effect or appropriate marking indication for the finally formed paper packaging box, the upper end of the waterproof layer 6 is coated or pasted with a printing layer 8. At the same time, considering the layout needs of the inner liner for different gifts, the inner liner layer 7 is an anti-static paper layer. In this way, the anti-static needs of some electronic products can be met. Of course, a velvet layer can also be selected as the placement needs of some ornaments, dolls, etc.

[0035] In addition, considering that water vapor may enter from the sandwich-like edge of the paperboard after the preparation of the paperboard, an edge sealing glue layer can be coated on the edge of the paperboard after the preparation of the paperboard. EVA glue can be selected. Of course, the edge sealing coating can also be performed at the cutting position after cutting according to the current paper box processing needs.

[0036] The working principle of the utility model is as follows:

[0037] First, the bearing core 9 with a concave-convex structure is processed by the plate pressing device and the folding device. Then, the upper hard paperboard layer 2 and the lower hard paperboard layer 3 are pasted on the upper and lower ends of the bearing core 9. Subsequently, the buffer glue 10 is poured into the bearing core 9. According to actual needs, an appropriate iron wire can be inserted before the buffer glue 10 is formed. After the buffer glue 10 is formed, the iron wire is extracted to form a buffer cavity 11. Alternatively, during the pouring of the buffer glue 10, the gas is not discharged, and the cavity formed by the gas is directly used to form the buffer cavity 11.

[0038] After that, the upper non-woven fabric layer 4 and the lower non-woven fabric layer 5 are laminated layer by layer. Finally, the waterproof layer 6 is adhered to the upper end surface of the upper non-woven fabric layer 4 by using a hot glue adhering process to form a waterproof film. The material of the inner lining layer 7 is selected to adhere to the lower end surface of the lower non-woven fabric layer 5.

[0039] After processing, the utility model is cut according to the shape of the packaging box through cutting equipment. Finally, it can be formed by folding and adhering.

[0040] As can be seen from the above text description and in combination with the drawings, after adopting the utility model, the following advantages are obtained:

[0041] 1. The sandwich structure is adopted, which has better supporting and isolating effects, meets the structural stability of the formed packaging box, and is convenient for protecting the contents.

[0042] 2. The paper core body adopts a filling structure, which can absorb external stress through the moderate deformation of the buffer glue inside, and will not be easily bent within the appropriate stress range, so that the packaging box has a better formed retention state.

[0043] 3. The upper and lower non-woven fabric layers are provided, which can improve the overall tensile effect and are not easy to tear.

[0044] 4. The waterproof layer is provided, which meets the waterproof needs during daily placement and avoids abnormal deformation of the formed gift box due to absorption of environmental moisture in a humid environment.

[0045] 5. The inner lining layer is provided, which can select appropriate materials according to needs to meet the placement needs of different gifts.

[0046] In addition, the indicated direction or position relationship described in the utility model is based on the direction or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or structure must have a specific direction or be operated in a specific direction, so it cannot be understood as a limitation of the utility model.

[0047] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principles of the utility model, a number of improvements and modifications can be made, which should also be regarded as the protection range of the utility model.
