Abstract

The utility model discloses a folded-bond fully-enclosed corrugated-paper box. In order to overcome the low compressive strength of the corrugated-paper box in the prior art, the edges of the box boards at the joints of the utility model present a staircase shape; the two box boards are bonded by layers; both two opposite box boards are provided with two opposite V-shaped impressions; the upper and the lower parts of box bodies are respectively provided with folding V-shaped impressions to form two opposite triangle box covers and square box covers. The utility model can be widely used in packing industry; the utility model is the substitute product and the development direction of the prior art.

Description

A kind of lap-bonded fully-inclosed corrugated paper box

The utility model relates to corrugated case, especially a kind of lap-bonded fully-inclosed corrugated paper box.

Corrugated case of the prior art is divided three classes, promptly folding class, three-dimensional class, heteromorpha.Wherein folding class carton has flat mouthful carton again, takes the branch of mouthful carton and big lid carton, its shape side of being body, boxboard is provided with vertical line ball and horizontal line ball, simultaneously the fluting, corner cut, boxboard engages nail joint mode or the gluing mode that connects of adopting, its shortcoming is: compressive strength is low, and is bonding insecure, also do not meet the environmental demands of packaging waste recycling.

The purpose of this utility model is to overcome the shortcoming that above-mentioned prior art exists, a kind of lap-bonded fully-inclosed corrugated paper box is provided, and it adopts the thin shell structure theory, and carton boxboard joint adopts the stepped appearance layering bonding, folding impression forms carton, need fluting, corner cut, nail case.

The purpose of this utility model realizes by following scheme: boxboard is provided with vertical line ball and horizontal line ball, the casing side of being body, stepped appearance is processed on the boxboard limit of joint and another boxboard limit, both layerings stick with glue and connect, be equipped with two opposed " V " shape impressions on opposed two boxboards, upper and lower two opposed triangle case lids, the square case lid that is respectively equipped with the formation of folding " V " shape impression of casing.

In addition, a square box covers to glued joint and has to take a tongue above or below the casing, square box that also can the casing above and below covers all to glued joint has one to take tongue, and this is taken tongue and is plugged in the crease that constitutes between mutually opposed with it square case lid that is folded to form and triangle case lid.

Cabinet wall glueds joint the composite corrugated cardboard of one deck.

The utility model need fluting, corner cut, binding, fluting, the low shortcoming of binding place intensity have been overcome, entire compression intensity height, single watt of carton falls 1.8m is not had breakage, compressive strength is being contained within heavy 15kg, the pile height 3m scope about 240kg, and single watt of carton can replace two watt prior art cartons, stock utilization is up to 98%, and every sq m consumption glue cost only is 0.04～0.05 yuan.
