Detailed Description

The utility model is further described in connection with the following detailed description in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1 to 4, the easy-open paper box according to the embodiment of the utility model comprises a paper box body, wherein the paper box body is made of white cardboard and comprises a front panel 5, one surface of the front panel 5 is connected with a left side plate 6, one surface of the left side plate 6 far away from the front panel 5 is connected with a rear panel 7, and one surface of the rear panel 7 far away from the left side plate 6 is connected with a right side plate 8. The one side that left side board 6 was kept away from to front panel 5 is provided with and pastes mouth 13, the both ends symmetry of front panel 5 is connected with inlayer and seals top panel 1 and inlayer and seal bottom panel 9, the both ends symmetry of rear panel 7 is connected with roof 3 and bottom plate 11, be provided with on the roof 3 and tear tape 14. The inner layer closed top panel 1 is in a convex shape, and the inner layer closed bottom panel 9 is in a trapezoid shape. The top of the left side plate 6 is connected with a first dustproof wing 2, the bottom of the left side plate 6 is connected with a third dustproof wing 10, the top of the right side plate 8 is connected with a second dustproof wing 4, and the bottom of the right side plate 8 is connected with a fourth dustproof wing 12.

Specifically, four right triangle notches are formed on two sides of the top plate 3, the four notches are distributed symmetrically on the central axis of the top plate 3 in pairs, and the bottom plate 11 is trapezoidal. The first dust-proof wing 2, the second dust-proof wing 4, the third dust-proof wing 10 and the fourth dust-proof wing 12 are all in a trapezoid design. The surfaces of the top plate 3 and the bottom plate 11 are provided with hot melt adhesive. The tear tape 14 is BOPP or PET. The white cardboard of the paper box body consists of face paper 15, core paper 16 and bottom paper 17.

During operation, the front panel 5, the left side plate 6, the right side plate 8, the bottom plate 11, the top plate 3 and the rear panel 7 can be unfolded in sequence to form a flat shape in the warehouse and transportation process, so that the space occupation rate can be greatly reduced, and when the product is required to be subjected to external packing, the front panel 5, the left side plate 6, the right side plate 8, the bottom plate 11, the top plate 3 and the rear panel 7 can be packaged into a finished product packaging box by using an automatic packaging machine. When the contents of the paper box body need to be taken, the paper box body can be easily torn from the position of the tearing adhesive tape 14, so that the internal product is taken out, and both directions can be torn. By applying hot melt adhesive to the top and bottom sheets 3, 11 on the packaging machine, the consumer can tear from the tear tape 14 during use. The design of the tearing adhesive tape 14 can be opened in two directions so as to replace the traditional zipper cutter, and the problem that the traditional paper box body is inconvenient to open in the opening position can be solved by the effective design of the two-way tearing position.

The raw materials of the paper box body of the utility model are white cardboard, the basis weight of white cardboard paper surface paper 15 and base paper 17 accounts for 10-25% of the specific gravity of the base paper, and the basis weight of core paper 16 accounts for 40-65% of the base paper. The production process of the white cardboard comprises pulping, deslagging, pulping, purifying, forming, squeezing, drying (steam temperature is 170-210 ℃), sizing, coating, and finally obtaining the white cardboard through soft matte and drying. The white card paper facestock 15 contains 65.+ -.5% bleached softwood kraft pulp (NBKP) +15.+ -.5% bleached kraft pulp (LBKP) +20% broke, the core paper (16) contains 50-60% chemimechanical pulp and 40-50% recycled system pulp, and the base paper 17 contains 45.+ -.5% bleached softwood kraft pulp (NBKP) +25.+ -.5% bleached kraft pulp (LBKP) +30% broke. The high number of applications of NBKP in the tissue 15 may increase its strength. The recycling of the pulp by a large number of application systems in the core paper can reduce cost, has good directivity, and further improves the tearing property of the paper box body.

The paper box body is opened in a mode of sticking the tearing adhesive tape 14, compared with the traditional paper box body opened in a zipper mode, the easy tearing effect is greatly improved, and meanwhile, the problem of difficult tearing or quality caused by the traditional paper box body opened in the zipper mode is avoided. The paper box body opening mode is a mode of sticking the tearing adhesive tape 14 at the opening position, is stuck on the inner surface of the paper box body, does not die-cut the paper box body, does not damage the paper box body, and does not influence the appearance experience of the paper box body. The characteristics ensure that consumers can not tear when tearing, and avoid the phenomena of damage and product pollution of the paper box body in the transportation process. According to the opening position of the paper box body, the design size of the transverse depth a is 8-12mm, the design size of the longitudinal depth b is 6-10mm, compared with the two sizes of the traditional paper box body which are 2-4mm, the width of the tearing adhesive tape 14 is 4-10mm, and the paper box is more convenient for being opened by removing the Sira by hands.

The comparison and testing experience is performed on the a transverse depth and the b longitudinal depth of the paper box body:

from the above data, it was found that the carton body was very prone to dust when the a-transverse depth reached 14mm and the b-longitudinal depth reached 12 mm. The carton body of the present application is provided with a transverse depth of 8-12mm and a longitudinal depth of 6-10mm.

The front panel 5, the left side plate 6, the right side plate 8, the bottom plate 11, the top plate 3 and the rear panel 7 can be unfolded in sequence to form a flat shape in the process of storage and transportation, so that the space occupation rate can be greatly reduced, and when products are required to be subjected to external packing, the front panel 5, the left side plate 6, the right side plate 8, the bottom plate 11, the top plate 3 and the rear panel 7 can be packaged into a finished product packaging box by using an automatic packaging machine. When the contents of the paper box body need to be taken, the paper box body can be easily torn from the position of the tearing adhesive tape 14, so that the internal product is taken out, and both directions can be torn. By applying hot melt adhesive to the top and bottom sheets 3, 11 on the packaging machine, the consumer can tear from the tear tape 14 during use.
