Detailed Description

As shown in fig. 1 to 4, a weight-bearing carton comprises an outer carton 1 and a liner 2, the liner 2 being disposed in the outer carton 1. The outer carton 1 is made of five-layer AB corrugated board, that is, comprises two corrugated layers and three paper layers respectively arranged at two sides of the corrugated layers, the thickness of the outer carton is usually 6-7mm, and the outer carton plays a role in packaging and main supporting. The paper board material of liner 2 is three-layer B corrugated container board, includes one deck flute layer and two-layer paper layer that are located the inside and outside both sides of flute layer respectively promptly, and the liner plays the auxiliary stay effect. Liner 2 includes that horizontally bottom plate 4 and two riser 3 that are located 4 left and right sides of bottom plate relatively, riser 3 and bottom plate 4 integrated into one piece, two relative inside walls of outer carton 1 are hugged closely respectively to two risers 3, the top height of riser 3 and the interior high parallel and level of outer carton 1, bottom plate 4 is arranged in on the diapire of outer carton 1. Corrugated core 5 in riser 3 sets up along vertical direction, and it is equipped with many reinforcement posts 6 to insert respectively in the corrugated core 5 of two risers, and the height that highly equals riser 3 of reinforcement post 6, and the hollow portion of corrugated core 5 has been filled to reinforcement post 6, has increased riser 3's support strength. The outer side wall of the vertical plate 3 is adhered with a fixed rib 7, the inner side wall of the outer carton 1 is provided with a pressure groove 8 matched with the position and the structure of the fixed rib 7, the fixed rib 7 can be embedded into the pressure groove 8, the vertical plate 3 and the outer carton 1 are firmly connected, and the vertical plate 3 is prevented from drooping into the carton, so that the rapid loading is not influenced; owing to set up fixed rib 7, when taking out the goods in the carton, riser 3 can not follow the goods and break away from out in outer carton 1 together, has guaranteed to get the goods fast. The reinforcing column 6 is pasted in the corrugated core layer 5 of the vertical plate 3 along the vertical direction, so that the reinforcing column 6 is fixedly connected with the corrugated core layer 5 and is not easy to drop from the corrugated core layer 5.

As shown in fig. 1 and fig. 3, the cross section of the fixing rib 7 is in an isosceles trapezoid structure, the fixing rib 7 comprises an adhesive surface 9 and a clamping surface 10 which are opposite, the width of the clamping surface 10 is larger than that of the adhesive surface 9, the adhesive surface 9 is adhered to the outer side wall of the vertical plate 3, the clamping surface 10 is embedded into the pressing groove 8, the fixing rib 7 on the vertical plate is pressed towards one side of the outer carton during assembly, the clamping surface 10 is embedded into the pressing groove 8, so that the fixing rib 7 is firmly connected with the pressing groove 8, and the fixing rib 7 cannot be separated from the pressing groove 8.

Fixed rib 7 is pasted on riser 3 along vertical direction, and consequently the indent 8 that matches with fixed rib 7 is vertical setting also, and for horizontal setting structure, this vertical indent structure has reduced owing to set up the influence that indent 8 and outside carton 1's support intensity produced, and vertical fixed rib 7 has also compensated the support intensity of indent 8 loss.

As shown in fig. 1, the length of the fixing rib 7 is 1/5-1/4 of the length of the vertical plate 3, and the fixing rib 7 is located at the upper side of the vertical plate 3, so that the vertical plate 3 can be more effectively fixedly connected with the outer carton 1, and the upper end of the vertical plate is prevented from falling off the outer carton 1.

The reinforcing columns 6 and the fixing ribs 7 are made of paperboards, leftover materials of the paperboards can be used for manufacturing the reinforcing columns and the fixing ribs, and material cost is reduced.

The manufacturing method of the carton comprises the following steps: two pressing grooves 8 are pressed at the positions corresponding to the fixing ribs 7 on the outer paper box 1, and then the outer paper box is cut and bound according to a conventional method. When making liner 2, paste many reinforcement posts 6 such as with riser 3 height with the hollow portion of the corrugated core layer 5 that riser 3 department corresponds, then paste the wrapping paper of applying liner 2 inlayer again, 4 both ends suppression preflex lines to the bottom plate of liner 2 again, then paste the face 9 of pasting of two fixed rib 7 on the lateral wall of riser 3 respectively, fold liner 2 again, form two risers 3 and a bottom plate 4, place folded liner 2 in outer carton 1, impress two fixed rib 7 in the indent 8 of outer carton 1, accomplish the preparation of carton.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
