Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to an inner lining packaging structure. Background Technology

[0002] Currently, cylindrical cosmetics (such as lipsticks, mascaras, and perfumes) are often packaged in rectangular boxes or cylinders. However, due to gaps between the cylindrical product and the inner wall of the rectangular box, or insufficient dimensional matching between the cylinder and the product, the product may wobble during transportation, easily causing damage. Furthermore, traditional packaging often requires additional materials such as foam and plastic for securing the product, increasing material costs and production processes, and contradicting current green and environmentally friendly development principles. Utility Model Content

[0003] Based on this, and in response to the aforementioned technical problems, this utility model provides an inner lining packaging structure.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An inner packaging structure, cut from corrugated cardboard, includes a rectangular inner liner body. One side of the upper surface of the inner liner body has a wrapping area. Folding plates are connected to the upper and lower edges of the inner liner body. The upper surface of the folding plates is divided into an adhesive application area and a non-adhesive application area. The position of the non-adhesive application area corresponds to the wrapping area of ​​the inner liner body. The lower edge of the upper non-adhesive application area and the upper edge of the wrapping area are respectively provided with an arc-shaped first fold line. The upper edge of the lower non-adhesive application area and the lower edge of the wrapping area are respectively provided with an arc-shaped second fold line. A circle is formed between the two first fold lines and the two second fold lines. When the two folding plates are folded towards each other and pasted on the upper surface of the inner liner body, and pressed inward along the first and second fold lines, the wrapping area and the corresponding non-adhesive application area are forced to bulge to form a cylindrical receiving cavity that can be used to accommodate the product.

[0006] Using the above technical solution, after the inner packaging structure is folded and glued into shape, simply pressing the various arc-shaped creases inwards causes the inner lining to bulge out, forming a cavity that conforms to the outer contour of the cylindrical product. When the cylindrical product is placed in this cavity, it prevents the product from shaking within the cavity, reducing the risk of damage caused by collisions and friction during transportation or handling. Secondly, the entire inner lining structure is cut from corrugated cardboard in one piece. Corrugated cardboard has flexible properties and can be directly used to wrap the product, eliminating the need for additional foam, plastic, or other auxiliary fixing materials. This not only reduces material costs and production processes but also aligns with the trend of green and environmentally friendly packaging, as it is easily recyclable and biodegradable, reducing environmental pollution. Furthermore, the overall structure is formed through cutting and crease design, simplifying the production process. It can be mass-produced using automated equipment, improving production efficiency and making it suitable for large-scale industrial production.

[0007] In a specific embodiment of this utility model, a paper ring is also included for fitting onto the inner liner body during winding to provide a restraining effect. Thus, the paper ring, fitted onto the inner liner body during winding, effectively restrains the winding shape, preventing it from loosening and facilitating storage and transportation.

[0008] In a specific embodiment of this utility model: the upper part of the inner liner body has a horizontal fold line. In this way, when it is necessary to open the inner liner to take out the product in the receiving cavity, the user can easily fold the upper part of the inner liner body outward with the help of the horizontal fold line, so that the user can easily and conveniently take out the product.

[0009] In this specific embodiment of the invention, the upper edge of the upper crease plate and the lower edge of the lower crease plate are both wavy edges. This enhances the visual appeal and makes the packaging more artistic and easily recognizable. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model is an inner packaging structure made of corrugated cardboard, including a rectangular inner lining body 10. A wrapping area 11 is located on one side of the upper surface of the inner lining body. Folding plates 12 are connected to the upper and lower edges of the inner lining body 10. The upper surface of each folding plate 12 is divided into an adhesive application area 121 and a non-adhesive application area 122. The position of the non-adhesive application area 122 corresponds to the wrapping area 11 of the inner lining body 10. A first arc-shaped crease line 123 is provided between the lower edge of the upper non-adhesive application area 122 and the upper edge of the wrapping area 11. A second arc-shaped crease line 124 is provided between the upper edge of the lower non-adhesive application area 122 and the lower edge of the wrapping area 11. A circle is formed between the two first crease lines 123 and the two second crease lines 124. During assembly, the two folding plates 12 are folded in opposite directions and then pasted onto the upper surface of the inner lining body 10. They are then pressed inward along the first fold line 123 and the second fold line 124, which forces the wrapped area 11 and the corresponding prohibited glue area 122 to bulge out and form a cylindrical receiving cavity 9 that can be used to accommodate the product.

[0020] In this way, the lining bulges out to form a cavity that conforms to the outer contour of the cylindrical product. When the cylindrical product is placed in this cavity, it prevents the product from shaking and reduces the risk of damage caused by collisions and friction during transportation or handling. Secondly, the entire lining structure is cut from corrugated cardboard in one piece. Corrugated cardboard has flexible properties and can be directly used to wrap the product without the need for additional auxiliary fixing materials such as foam or plastic. This not only reduces material costs and production processes but also conforms to the trend of green and environmentally friendly packaging, as it is easily recyclable and biodegradable, reducing environmental pollution. In addition, the integral structure is formed through cutting and crease design, simplifying the production process. It can be mass-produced using automated equipment, improving production efficiency and making it suitable for large-scale industrial production.

[0021] Combination Figure 5 and Figure 6 As shown, in this embodiment, a paper ring 13 is also included for fitting onto the inner liner body 10 during winding to provide a restraining effect. Thus, the paper ring, fitted onto the inner liner body during winding, effectively restrains the winding shape, preventing it from loosening and facilitating storage and transportation. Of course, it can also be secured using straps or rubber bands.

[0022] Combination Figure 7 As shown, in this embodiment, a horizontal crease line 101 is provided on the upper part of the inner liner body 10. In this way, when it is necessary to open the inner liner to take out the product in the receiving cavity, the user can easily fold the upper part of the inner liner body outward with the help of the horizontal crease line, so that the hidden upper part of the product can be naturally exposed, making it easy for the user to take out the product smoothly and conveniently.

[0023] like Figure 2 As shown, in this embodiment, the upper edge of the upper crease plate 12 and the lower edge of the lower crease plate 12 are both wavy edges. This enhances the visual appeal and makes the packaging more artistic and easily recognizable.

[0024] The above describes an inner packaging structure of this utility model. During assembly, the two folding plates 12 are folded towards each other and then pasted onto the upper surface of the inner liner body 10. Then, they are pressed inward along the first fold line 123 and the second fold line 124, causing the inner liner to bulge and form a cylindrical receiving cavity. The product is then placed into the receiving cavity 9. If the product is relatively large, the two folding plates 12 can be left unpainted initially; the inner liner can be opened directly to form a receiving cavity, and the product placed inside before pasting the two folding plates 12. After the product is placed into the receiving cavity, the inner liner body 10 is rolled up and secured with a paper ring 13. In use, the user removes the paper ring 13, unfolds the rolled-up inner liner body 10, and folds the upper part of the inner liner body outward along the transverse fold line, revealing the hidden upper part of the product. The product is then removed.

[0025] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
