The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in Fig. 1,2,3,4,5, be folded to form by the broken line on it by a cardboard; The left and right sides lid 2,3 that structure on mainly comprising cuboid base 1 and being connected described base is identical;
Described base 1 has a square floor 11; Be connected with first side plate 12, second side plate 13, the 3rd side plate 14 and the 4th side plate 15 on four sides of described square floor 11 respectively, wherein first side plate 12 and the 3rd side plate 14 are oppositely arranged, and second side plate 13 and the 4th side plate 15 are oppositely arranged; Be connected with a top board 16 on described the 3rd side plate 14; Connect the first bonding flap sheet 17 and the second bonding flap sheet 18 on two opposed side edges of described top board 16 respectively, described base 1 has cardboard by the broken line folding forming on it, wherein the first bonding flap sheet 17 and second side plate, 13 inwalls are bonding, and the second bonding flap sheet 18 and the 4th side plate 15 inwalls are bonding; After the moulding, base plate 11 is as the bottom surface of whole box body, 16 on top board as in the lid of the left and right sides, be used for the plane of exhibiting product; The space that described top board 16 and left cover 2, right cover plate 3 are surrounded is takes in and spacial flex; First side plate 12 is not bonding with other panels, therefore can free opening and closing, and base plate 11, top board 16 and four base inner spaces that side plate surrounded also can be used for taking in product;
All have a side cover plate 21 on the lid of the described left and right sides, wherein the side cover plate base of left cover body 2 links to each other with second side plate 13, and the side cover plate base of right cover body 3 links to each other with the 4th side plate 15, and promptly described left and right sides lid links to each other with base by side cover plate; The top margin of described side cover plate 21 connects a lamina tecti 22, identical front shroud 23 and the back shroud 24 of difference connection structure on other two opposed side edges; Described lamina tecti 22, front shroud 23 and back shroud 24 folding backs are taking in and spacial flex of whole box body top with the space that side cover plate 21 is surrounded, and all are connected with bonding flap sheet 25 on two relative sides of described lamina tecti 22; Described two bonding flap sheets are bonding with the inwall of front shroud 23 and back shroud 24 respectively, and in conjunction with the accompanying drawings as can be known, left cover body 2 is identical with the structure of right cover body 3; Left and right sides lid can rotate by itself and the connection side of side plate, finishes the unlatching and the closure of box body upper space.
Be connected with a secondary top board 221 identical on the described lamina tecti 22 with lamina tecti 22 structures; Described secondary top board 221 is bonding with inwardly folding back of the broken line between the lamina tecti 22 and lamina tecti 22 by it.
Be connected with first auxiliary coverplate 231 on the described front shroud 23, be connected with second auxiliary coverplate 241 on the back shroud 24; Described first auxiliary coverplate 231 is inwardly folding and bonding with front shroud 23, and second auxiliary coverplate 241 is inwardly folding and bonding with back shroud 24; Described two bonding flap sheets 25 are wrapped between first auxiliary coverplate 231 and the front shroud 23 respectively and between second auxiliary coverplate 241 and the back shroud 24.
In conjunction with Fig. 5, be plane outspread drawing of the present invention as can be known, adopt lamina tecti 22 and secondary top board 221, the front shroud 23 and first auxiliary coverplate 231, the mutual folded, glued of the back shroud 24 and second auxiliary coverplate 241, mainly be to adopt double-deck box wall construction, one can increase the deflection and the planeness of box body, the 2nd, because if adopt individual layer box wall, because in the cutting process of cardboard, its line of cut can be sharper, the overall appearance that is unfavorable for box body, the mutual folded, glued by cover plate seamlessly transits on line of cut, strengthen the attractive in appearance of box body, and help opening and the sense of touch when closed.
Between described front shroud 23 and the side cover plate 21, all be connected with an extended surface 26 between back shroud 24 and the side cover plate 21; Described extended surface 26 adopts isosceles triangular structure; A wherein waist limit of described equicrural triangle is the side of side cover plate 21, and another waist limit is arranged on the front and rear cover plate 23,24; Also be provided with broken line 27 on the described extended surface 26, broken line 27 is the height on the equicrural triangle base in this, and broken line 27 in invagination is somebody's turn to do extends to lid portion inside after the described extended surface doubling, and the extended surface after the doubling is bonding mutually; On the described side cover plate 21, the outer broken line 28 of the level that is provided with between the summit of two triangle extended surface; Because after the extended surface folded, glued, side cover plate 21 can shrink because of stressed, therefore be provided with and helped the lid moulding of the whole left and right sides by outer broken line 28.
Described side cover plate 21 adopts isosceles trapezoidal structure, copys the structure of diamond, and the isosceles trapezoidal structure of short, the following length of side in top is adopted on the plane of side cover plate 21, makes that whole moulding svelteness is clearly demarcated, and left and right sides lid presents regular polyhedral structure.
All be connected with dustproof flap sheet 19 on the limit, two opposite sides of described second side plate 13 and the 4th side plate 15, described dustproof flap sheet 19 inserts in the base 1.
The base of described first side plate 12 links to each other with base plate 11; Also be connected with a plate 121 on the top margin relative on described first side plate 12 with the base; Described plate 121 inserts in the base 1.
Also offer manhole 20 on described lamina tecti 22 and the secondary top board 221, after whole packing box moulding, a strapping is set between two manholes 20, be used for left and right sides lid is bundled, improve moulded aesthetic feeling.
Certainly, above-mentioned explanation is not a limitation of the present invention, the present invention also be not limited to above-mentioned for example, those skilled in the art within the scope of the invention, the variation of making, change and add or replace, and all should belong to protection scope of the present invention.
