Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] refer to Figures 1-4 As shown, a double-layered gift box is made of 3D sheet material and cardboard, including an outer box 1, an inner box 2, and a lid 3.

[0027] The outer box 1, inner box 2, and lid 3 form a dual-product structure, meaning this gift box preferably adopts a traditional double-bottle size structure. Both the outer box 1 and inner box 2 are rectangular structures with openings at the top. The outer box 1 is slightly larger than the inner box 2, allowing the outer box 1 to wrap around the outside of the inner box 2. The lid 3 is a rectangular plate structure that flips open and closes at the opening of the outer box 1 and / or the inner box 2, allowing the opening to be covered or opened.

[0028] The outer box 1 is made of 3D sheet material, ensuring a beautiful and elegant appearance. The sheet material not only creates a sturdy exterior but also allows for cold foil stamping to create attractive patterns, and can also be used to design anti-counterfeiting designs. The inner box 2 is made of paper, used to support the shape of the outer box, maintaining its good shape and providing internal protection and shock absorption for the product. The box lid 3 is also made of paper, forming a flat lid and preventing warping issues common with 3D box lids.

[0029] The outer box 1 includes an integrally structured outer box side panel 11, outer box bottom panel 12, and outer box flange 13. The outer box side panel 11, outer box bottom panel 12, and outer box flange 13 are preferably made of PET grating sheet. The inner box 2 includes an inner box side panel 21 and a box lid support edge 23, which are structurally independent.

[0030] The outer box side panel 11 forms a four-sided rectangular cylindrical structure, and the inner box side panel 21 forms a four-sided rectangular cylindrical structure. Both cylindrical structures are preferably pre-processed, one-piece four-sided structures. The outer box side panel 11 wraps around the outer side of the inner box side panel 21, and the inner box side panel 21 supports the outer box side panel 11. The outer side panel 11 has a cold-stamped pattern, with aesthetically pleasing and layered embossed lines. Anti-counterfeiting features are also designed on the outer side panel 11.

[0031] The upper part of the outer box side panel 11 is integrally connected to an inwardly folding outer box flange 13. The outer box flange 13 wraps around and is glued to the upper part of the inner box side panel 21, protecting the upper part of the inner box cardboard and forming a connection and fixation between the inner and outer boxes. The remaining sheet material, excluding the flange, is also glued to the cardboard to achieve overall fixation of the cardboard and sheet material. The four outer box bottom panels 12 form a hook-bottom structure to seal the bottom.

[0032] The inner box side panel 21 has a lid support edge 23 at the upper opening. The lid support edge 23 is glued to the inside of the outer box flange 13. The lid support edge 23 is only provided on the left, right and back of the gift box. The lid support edge 23 cooperates with the lid 3 to prevent the lid from sinking. It also plays a supporting and shaping role.

[0033] The lid 3 includes a lid tail edge 31, a lid main board 32, a lid insert edge 33, a carrying strap 34, and a gasket 35. Bending lines are provided between the lid tail edge 31 and the lid main board 32, and between the lid main board 32 and the lid insert edge 33, forming a connection method for relative flipping and opening.

[0034] The lid's tail edge 31 connects to the opening of the outer box 1 and / or the inner box 2, specifically glued between the lid support edge 23 and the outer box's flip edge 13, allowing the lid main plate 32 and the lid insert edge 33 to flip open and close. The lid main plate 32 matches the shape of the inner box 2's opening, forming a rectangular plate structure to cover and close the opening. The lid insert edge 33 engages with the opening of the inner box 2, ensuring a stable seal.

[0035] A carrying strap 34 is located on the outer side at the bend between the main body 32 of the lid and the lid insert edge 33. The carrying strap 34 makes it easy to lift the lid and facilitates opening and closing control. A pad 35 is provided on the inner side of the main body 32 of the lid, which is opposite to the product position. If there is a dual product position, one pad is arranged on each side. The flexible pad 35 can play a cushioning role and reduce friction between the bottle and the box.

[0036] The foregoing basic examples and their further alternative examples of this utility model can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and are claimed by this utility model. In the solution of this utility model, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
