[0063] The height of the right side cover body 2a1 is equal to the horizontal distance C between the left side edge of the front cover body 2b1 and the left side edge of the back side 1b of the box body.

[0064] The height of the left cover body 2c1 is equal to the horizontal distance A between the right side edge of the front cover body 2b1 and the right side edge of the back side 1b of the box body.

[0065] The two ends of the insertion port 1d1 can be chamfered or rounded upward or downward to facilitate insertion during packaging.

[0066] A right inner glue coating area 1e1 is arranged on the right inner side surface 1e of the box body.

[0067] A front fold block glue coating area 1i1 is provided on the front fold block 1i of the box body.

[0068] Figure 1 Only an upward chamfer is shown in the figure, and a downward chamfer or a straight knife line without cutting the corner may also be used to facilitate the insertion of the tail end 2b2 of the positive sealing sheet.

[0069] A right inner glue coating area 1e1 is arranged on the right inner side surface 1e of the box body.

[0070] A front fold block glue coating area 1i1 is provided on the front fold block 1i of the box body.

[0071] Except for the connection between the back side 1b of the box body and the front sealing sheet 2b, the lengths of the two sides at the connection points of the other folding blocks are equal.

[0072] There are many ways to fold the packaging paper in this embodiment 1. The following is only one example. The folding is performed along the indentation line:

[0073] 1. Folding packaging paper body 1:

[0074] First, place the packaging paper vertically, and fold the right outer side fold block 1f, the back side fold block 1g, the left side fold block 1h, and the front side fold block 1i of the box body backward and upward ("back" refers to the position away from the person / object) by 90 degrees, so that these fold blocks remain horizontal;

[0075] Then, the left side surface 1c of the box body and the folding block connected to the left side are folded backwards 90 degrees, and the right inner side surface 1e of the box body is folded backwards 90 degrees;

[0076] Fold the back side 1b of the box body and the folding block connected to its left side forward 90 degrees, so that the back side 1b of the box body is parallel to the front side 1d of the box body, first fold the right outer side folding block 1f of the box body and the left side folding block 1h of the box body to the innermost side of the box body, then close the front side folding block 1i of the box body and the back side folding block 1g of the box body, and after applying glue on the front folding block glued area 1i1 of the front side folding block 1i of the box body, glue the back side of the back side folding block 1g of the box body to the front folding block glued area 1i1;

[0077] After gluing the glue area 1e1 on the right inner side 1e of the box body, the right outer side 1a of the box body is folded forward 90 degrees, so that the inner side of the right outer side 1a of the box body is bonded to the right inner side 1e of the box body.

[0078] The above is a folding method of an existing soft package box. After folding, the upper end is open and the other five sides are closed.

[0079] 2. Folding top cover 2:

[0080] On the basis of the above, fold the right side cover 2a and the left side cover 2c downward 90 degrees so that both cover the opening at the upper end, then fold the front cover 2b forward 90 degrees so that the front cover body 2b1 covers the right side cover 2a and the left side cover 2c and covers the rest of the opening at the upper end, then fold the rear end 2b2 of the front cover downward 90 degrees and insert it into the insertion port 1d1 so that the entire box body is closed.

[0081] Figure 1 For the packaging paper of this embodiment 1, part I, namely the packaging paper body 1, is the small box packaging body part in the prior art, and part II, namely the top cover 2, is a newly added folding block group.

[0082] Figure 2 This is a schematic diagram of a fully enclosed soft box packaging box obtained by folding the wrapping paper of this embodiment. The dotted line part indicates the inside of the box body. The left picture is a schematic diagram of the packaging box during packaging, and the right picture is a schematic diagram of the complete packaging box.

[0083] Figure 2 In the embodiment, after the positive sealing sheet 2b is folded down, it covers the right sealing sheet 2a and the left sealing sheet 2c to form a six-sided complete packaging box. On the front of the packaging box, the positive sealing sheet tail end 2b2 on the positive sealing sheet 2b is inserted into the insertion port 1d1 to form a stable packaging body, so it is not necessary to apply glue, and the positive sealing sheet 2b can be repeatedly opened and closed during use. This new structure of product packaging, combined with appropriate appearance design, can achieve a more comprehensive visual performance and more adequate protection for the packaged object 5 than the existing soft box cigarette pentahedron packaging. Compared with the existing soft box cigarette pentahedron packaging paper, the packaging material of this packaging paper will only increase by about 10-30%, the cost increase is small, but the efficiency of box packaging molding and packaging quality are improved.

[0084] Example 2

[0085] Figure 3 This is a schematic diagram of the packaging paper structure of this embodiment 2, and the double-dotted line part is the indentation line.

[0086] Compared with the packaging paper of Example 1, the differences are:

[0087] The height B of the right sealing sheet body 2a1 is greater than or equal to the horizontal distance C between the left side edge of the front sealing sheet body 2b1 and the left side edge of the back side 1b of the box body.

[0088] The height B of the left cover sheet body 2c1 is greater than or equal to the horizontal distance A between the right side edge of the front cover sheet body 2b1 and the right side edge of the back side 1b of the box body.

[0089] The positive sealing sheet tail end 2b2 is rectangular, and the right sealing sheet body 2a1, the left sealing sheet body 2c1, and the positive sealing sheet tail end 2b2 are of equal height to facilitate the processing of the packaging paper.

[0090] Change the insertion port 1d1 area to the top cover glue coating area 1d2.

[0093] Example 3

[0094] Figure 5 This is a schematic diagram of the packaging paper of this embodiment 3, and the double-dotted line portion is the indentation line.

[0095] Figure 6 The diagram is a schematic diagram of a fully enclosed soft box packaging box obtained by folding the wrapping paper of this embodiment. The dotted line part indicates the inside of the box body. The left figure is a schematic diagram of a complete packaging box, and the right figure is a schematic diagram of the packaging box when it is in use.

[0096] Based on the packaging paper of Example 2,

[0097] A non-closed curve or a non-closed non-curve-shaped opening 2c11 is cut and provided near the left sealing sheet end 2c2 on the left sealing sheet 2c. A non-closed curve-shaped opening 2a11 is also provided on the right sealing sheet 2a. The connection between the left sealing sheet 2c and the left side surface 1c of the box body is a dotted cut line 4.

[0098] When it is possible or necessary to take out the packaged objects 5 in an incomplete manner, for example, when the packaged objects 5 are products that are not to be used up all at once, such as multiple cigarettes, snacks, multiple injections, etc., it is not necessary to disassemble the relatively long front sealing sheet 2b. Instead, the pull-opening 2c11 can be opened with the fingernails, and after lifting the left sealing sheet 2c, the packaged objects 5 can be taken out for use in batches, thereby ensuring the cleanliness and integrity of the packaged objects 5 and making better use of the packaging of the product to fully protect the product.

[0099] After lifting the pull mouth 2c11, if it is considered that the left side sealing sheet 2c will cause inconvenience to subsequent use, the left side sealing sheet 2c and the connected folding block can be torn off from the dotted knife line 4 at the root of the left side sealing sheet 2c after taking out the packaged object 5 and starting to use it. This is also more practical for products that can be consumed in a short time, such as cigarettes and snacks, and is in line with people's existing consumption habits.
