Abstract

Disclosed is a corrugated box which can automatically lock the bottom. The utility model has the technical proposal that a lower inner shaking cover is made into the shape of a trapezium; a triangular clamping opening is arranged in a lower outer shaking cover and the front part of the lower outer shaking cover is made into a folded angle by being folded 45 DEG; the folded angle is coated with bond and fixed with one side of the lower inner shaking cover. The utility model simplifies packing process, saves manhour, prevents the bottom of the box from unravelling, prevent articles from being stolen from the bottom, prevents the box from being reused, and avoids the appearance of fake packing boxes.

Description

Paper box with self locking bottom

The utility model belongs to a kind of package packing supplies, formula corrugated case at the bottom of particularly a kind of automatic lock.

Existing corrugated case structure has counterpart case, counterpart case of the dead end etc., the counterpart case, and it needs the user to spend the other end with hand channel, could use, and wastes time and energy, and the content product come off through the bottom of being everlasting simultaneously, and article are damaged.Counterpart case of the dead end, it when manufacturing just fixing dead at the bottom of the case, during use without people with the other end of hand, prevented that also the thing that content product come off in the bottom from taking place, but it can not be folded into tabular, it is big to take up room, and is unfavorable for transportation and storage.

The purpose of this utility model provides formula corrugated case at the bottom of a kind of automatic lock, and it can simplify packaging process, saves man-hour, prevents from that carton bottom from opening to loose and from the generation of the stolen phenomenon of bottom article.Prevent the carton recycling, prevent the appearance of pseudo-packing.

The purpose of this utility model is achieved in that it is to be made of front plate, side panel, upper outside rolling cover, upper interior rolling cover, lower outside rolling cover, lower inside rolling cover, wherein lower inside rolling cover is made for trapezoidal, all being provided with the triangle bayonet socket and lower outside rolling cover front portion is made in lower outside rolling cover can be by 45 ° of folding knuckle, coating adhesive on knuckle, knuckle and lower inside rolling cover one side bonds are fixed.

Isolated edge 25-35mm place horizontally set has a tangent line on upper outside rolling cover.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a flat deployable structure scheme drawing of the present utility model.

Fig. 2 is status architecture schematic diagram before the closure at the bottom of the utility model case.

Fig. 3 is status architecture schematic diagram after the closure at the bottom of the utility model case.

See Fig. 1-3, the utility model forms the casing wall by front plate 1 and side panel 2, top be connected with upper outside rolling cover 8 and in rolling cover 7, be connected with lower outside rolling cover 4 and lower inside rolling cover 3 at lower box, wherein lower inside rolling cover 3 is made trapezoidally, makes triangle bayonet socket 5 at lower outside rolling cover 4 middle parts, bayonet socket 5 degree of depth equate with lower outside rolling cover scrap (bridge) width, and lower outside rolling cover 4 front portions are made and can scribble adhesive at knuckle 6 by 45 ° of folding knuckles 6, knuckle 6 is fixed with lower inside rolling cover 3 one side bonds.Outer rolling cover 8 every sides leave the wide tangent line 9 of easily taking off of 30mm on the carton, and after carton sealed and opens, both sides had respectively that 30mm is wide to be torn with sealing strip, thereby carton can not second use, prevents that carton from utilizing again and the appearance of pseudo-packing.The process for making of carton be earlier carton bottom after die-cutting machine processing, the nail case, folding at the bottom of the case, knuckle and lower inside rolling cover one side bonds aftershaping.

The utility model is owing to adopt trapezoidal lower inside rolling cover, triangle bayonet socket and angle folding version, behind this carton forming, still can be folded into the tabular transportation, after arrival comprises production line, as long as the case bottom bracing is opened, namely automatically recover closure state at the bottom of the case, need not manually go to the other end, simplify packaging process, save man-hour, no matter therefore be carton factory or packing user, the most suitable automated production of this structure.

Claims

1, a kind of paper box with self locking bottom, it is to be made of front plate, side panel, upper outside rolling cover, upper interior rolling cover, lower outside rolling cover, lower inside rolling cover, it is trapezoidal to it is characterized in that lower inside rolling cover is made for, all being provided with the triangle bayonet socket and lower outside rolling cover front portion is made in lower outside rolling cover can be by 45 ° of folding knuckle, coating adhesive on knuckle, knuckle and lower inside rolling cover one side bonds are fixed.

2, carton according to claim 1 is characterized in that outside last isolated edge 25-35mm place horizontally set has a tangent line on the rolling cover.
