Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, specifically to a modular packaging box. Background Technology

[0002] Packaging boxes mainly refer to containers used for product packaging. In most existing packaging boxes, the internal space is often larger than the volume of the product, resulting in a large space between the product and the packaging box. This limits the packaging box's resistance to deformation and also increases the risk of the product shifting and being damaged inside the packaging box, especially for fragile products such as glassware and alcoholic beverages.

[0003] For packaging boxes of such products, cardboard is often added inside the box to fit the product and restrict its movement. However, when the box is subjected to external pressure, there is still space between the product and the box for the box to deform. This can cause the box to deform and the product inside to be crushed and damaged, thus affecting the protective effect of the box on the product. Utility Model Content

[0004] The purpose of this utility model is to provide a modular packaging box that can reduce the risk of product displacement and damage during carrying and transportation, and improve the protection of the product.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A modular packaging box, comprising:

[0007] The outer shell, which is used to hold the product, has a hollow structure.

[0008] Several inner shells are used to wrap around the product, and the inner shells are located between the outer shell and the product;

[0009] The inner shell is sheet-shaped and has several through holes arranged in a straight line at equal intervals. When the inner shell is folded, the through holes are connected in sequence to form a receiving groove that matches the shape of the product.

[0010] As a further definition of this utility model, the outer shell includes a first side piece, a second side piece, and a third side piece. The first side piece, the second side piece, and the third side piece are arranged in a straight line and are connected to each other by connecting pieces. The left and right ends of the connecting piece are respectively provided with a bottom piece and a top piece.

A first insertion hole for inserting the first insert piece is opened between the third side piece and the connecting piece, and a second insert piece is provided therein. A second insertion hole for inserting the second insert piece is opened between the first side piece and the first insert piece. One of the two second sealing pieces is provided with a third insert piece, and a third insertion hole for inserting the third insert piece is opened between the other second sealing piece and the connecting piece.

[0011] As a further limitation of this utility model, both the first and second sealing sheets are provided with a plurality of extension pieces, and the extension pieces on both are staggered, with the distance between adjacent ends of the extension pieces being the same as the width of the extension piece.

[0012] As a further limitation of this utility model, the inner shell includes a plurality of inner lining sheets connected in sequence, and one or more through holes are provided on the inner lining sheets. The inner lining sheets are arranged in a straight line and have the same number of through holes. The size of the through holes on the inner lining sheets decreases sequentially along the arrangement direction of the inner lining sheets.

[0013] As a further limitation of this utility model, the top sheet is provided with an easy-tear line and is divided into a connecting part and a separating part by the easy-tear line, and the first adhesive strip is located on the separating part.

[0014] As a further limitation of this utility model, the smallest through hole in the inner shell is located on the edge of the top of the inner liner sheet, and a slot is formed therein.

[0015] As a further limitation of this utility model, the smallest through hole in the inner shell is located on the top of the inner lining piece, and a carrying rope is provided. The two ends of the carrying rope are respectively fixed to the inner lining piece. The first side piece, the second side piece, and the third side piece are all provided with strip-shaped holes for the carrying rope to pass through.

[0016] Compared with the prior art, this utility model has the following advantages and effects:

[0017] (1) By combining the outer shell and the inner shell, this utility model enables the product to be positioned inside the packaging box, reducing the space between the product and the packaging box, and reducing the risk of the product being moved and damaged during carrying and transportation. Combined with the folding structure of the inner shell and the wrapping and restricting effect of the outer shell on the inner shell, the structural strength of the inner shell is guaranteed, and the difficulty of the inner shell being deformed under external pressure is increased, thereby improving the protective effect of the packaging box on the product.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0029] Example 1.

[0030] See Figures 1-5 This embodiment provides a modular packaging box, including an outer shell 1 for holding a product and several inner shells 2 for wrapping the product. The outer shell 1 is hollow, and the inner shells 2 are located between the outer shell 1 and the product. The inner shells 2 are sheet-like, and have several through holes 3 arranged in a straight line at equal intervals. The inner shells 2 are foldable, and when folded, the through holes 3 are sequentially connected to form a receiving groove 31 that conforms to the shape of the product. In use, the product is wrapped by clamping the two inner shells 2, and then the inner shells 2 containing the product are placed into the cavity of the outer shell 1, so that the outer shell 1 wraps around the inner shells 2. Finally, the outer shell 1 is closed to complete the packaging of the product.

[0031] See Figure 2 , Figure 3 The outer shell 1 includes a first side panel 11, a second side panel 12, and a third side panel 13. The first side panel 11, the second side panel 12, and the third side panel 13 are arranged in a straight line and are connected to each other by connecting pieces 14. A bottom piece 15 and a top piece 16 are respectively provided on the left and right ends of the connecting piece 14. A first sealing piece 41 and a second sealing piece 42 are respectively provided on the left and right ends of the second side panel 12 and the third side panel 13. A first adhesive strip 43 is provided on the top piece 16 for connecting the top piece 16 and the second sealing piece 42 or between two top pieces 16. The first sealing piece 41... A second adhesive strip 44 is provided for connection with the base plate 15. A first insert 51 is provided on the first side plate 11. A first insertion hole 52 for inserting the first insert 51 is opened between the third side plate 13 and the connecting plate 14, and a second insert 53 is provided. A second insertion hole 54 for inserting the second insert 53 is opened between the first side plate 11 and the first insert 51. A third insert 55 is provided on one of the two second sealing plates 42, and a third insertion hole 56 for inserting the third insert 55 is opened between the other second sealing plate 42 and the connecting plate 14.

[0032] During the molding of the outer shell 1, the first side piece 11, the second side piece 12, and the third side piece 13 are folded along the fold line between them and the connecting piece 14 until the first side piece 11 covers the third side piece 13. Then, the first insert piece 51 is inserted into the first insertion hole 52, and the second insert piece 53 is inserted into the second insertion hole 54 to complete the connection between the first side piece 11 and the third side piece 13. Then, the bottom piece 15 is folded along the fold line between it and the connecting piece 14 so that the bottom piece 15 is located in the cavity formed by the first side piece 11, the second side piece 12, the third side piece 13, and the connecting piece 14. Then, the first sealing piece 41 is folded along the fold line between it and the second side piece 12 or the third side piece 13 so that the first sealing piece 41 covers the bottom piece 15 and the two are connected by the second adhesive strip 44, thereby completing the molding operation of the outer shell 1 with an open top and a closed bottom.

[0033] After the inner shell 2 containing the product is placed inside the outer shell 1, the second sealing sheet 42 is folded along the fold line between it and the second side sheet 12 or the third side sheet 13, so that the second sealing sheet 42 covers the inner shell 2. Then, one of the two top sheets 16 is folded along the fold line between it and the connecting sheet 14 and covers the second sealing sheet 42. The two are then connected by the first adhesive strip 43. Subsequently, the other top sheet 16 is folded along the fold line between it and the connecting sheet 14 and covers the first folded top sheet 16. The two are then connected by the first adhesive strip 43, completing the sealing operation of the top of the outer shell 1.

[0034] See Figure 3 The top sheet 16 is provided with an easy-tear line 6, which divides it into a connecting part 61 and a separating part 62. The first adhesive strip 43 is located on the separating part 62, which enables the packaging box to be opened by tearing the top sheet 16 along the easy-tear line 6, thus improving the convenience of operation.

[0035] See Figure 3 Each of the first sealing sheet 41 and the second sealing sheet 42 is provided with a plurality of extension pieces 7, and the extension pieces 7 on the two are staggered. The distance between the two adjacent ends of the extension pieces 7 is the same as the width of the extension piece 7. When the two first sealing sheets 41 and the two second sealing sheets 42 are folded together, they can form an interlocking effect through the extension pieces 7 on both, which expands the effective contact area between them. At the same time, the two first sealing sheets 41 can be connected through the second adhesive strip 44 and the extension pieces 7, and the two second sealing sheets 42 can be connected through the top piece 16 and the first adhesive strip 43, thereby ensuring the connection strength between them while improving the sealing effect of the top and bottom of the outer shell 1.

[0036] See Figure 4 , Figure 5The inner shell 2 includes several inner lining sheets 21 connected in sequence. Each inner lining sheet 21 has one or more through holes 3. The inner lining sheets 21 are arranged in a straight line and have the same number of through holes 3. When the inner lining sheets 21 are folded over each other and stacked in sequence, the through holes 3 on adjacent inner lining sheets 21 can be connected. Thus, when the inner shell 2 is in a folded state, it can form a receiving groove 31 for placing the product, thereby achieving the effect of clamping and wrapping the product through the two inner shells 2. The size of the through holes 3 on the inner lining sheets 21 decreases sequentially along the arrangement direction of the inner lining sheets 21, which improves the fit between the inner shell 2 and the product and ensures the restriction effect of the inner shell 2 on the displacement of the product.

[0037] Example 2.

[0038] See Figure 6 The structure of this embodiment is basically the same as that of the modular packaging box in Embodiment 1, except that the smallest through hole 3 among the through holes 3 on the inner shell 2 is located on the edge of the top of the inner lining 21, where a slot 8 is provided. When the inner shell 2 is inside the outer shell 1, a space for inserting fingers can be formed between the inner shell 2 and the outer shell 1 through the slot 8. This allows the inner shell 2 to be pulled out from the outer shell 1 by pinching it with two fingers when the packaging box is placed horizontally, reducing the difficulty of separating the inner shell 2 and the outer shell 1 and improving the convenience of use.

[0039] Example 3.

[0040] See Figure 7 , Figure 8 The structure of this embodiment is basically the same as that of Embodiment 1 and Embodiment 2. The difference is that the smallest through hole 3 in the inner shell 2 is located on the top of the inner lining piece 21 and a carrying rope 9 is provided. The two ends of the carrying rope 9 are fixed to the inner lining piece 21 respectively. The first side piece 11, the second side piece 12 and the third side piece 13 are all provided with strip holes 91 for the carrying rope 9 to pass through. This not only enhances the visual effect of the packaging box, but also improves the convenience of carrying.

[0041] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
