Abstract

The present invention provides a packaging case/box which belongs to the technical field of a packaging container. The present invention has the technical characteristics that marks are pressed on a material which is expanded into a rectangle, gaps can not be cut on the periphery of the material which can not be formed into an irregular outline, and the material can be folded and expanded according to the pressed marks to be formed into a rectangular packaging container. The present invention can be used for packing various forms, such as water resistance, damp resistance, dust prevention, inflation, vacuum packaging, etc. and various articles and can also be used for packing liquid materials.

Description

A kind of packing chest

The invention belongs to the packing chest technical field, particularly use the composite panel of various paper, cardboard, combination board, paper, plastics, metallic membrane, fibre, the folding osed top cuboid packing chest that plastic flagstone, calcium-plastic board and other plastic blending material plate equal strength, rigidity material better, that folding is folded are made.

Known expansion plane is that the rectangle, its periphery of rule is the folding osed top cuboid packing chest of continuous straight line (as European patent EP-0176278 etc.), can only be folded into the plain film that the bench section folds for the two layers of material plate, its width is the width sum of a facade of packing chest and a upright side, floor area is big, and inconvenience is deposited, carries, carried; Under the state that forms the cuboid packing chest, at one end sealed, in it during empty, can not be folded into a plain film; Under the state that is folded into a plain film, its two ends all are openings, as long as with the one end closure, just can not open the packing chest that forms cuboid, can only form under the cuboid state at packing chest when connection with wrapping of piece, it could be sealed, and use inconvenient.

The purpose of this invention is to provide a kind of plane of launching and be the folding osed top cuboid packing chest of continuous straight line for regular rectangle, its periphery, can be folded into the bench section is the plain film that four layer material plates fold, its width is the width of a facade of packing chest, and floor area is little; Under the state that forms the cuboid packing chest, at one end sealed, in it during empty, can be folded into a plain film; Under the state that is folded into a plain film, when at one end being sealed, can open and form a cuboid, easy to use; Be folded under the state that two upright side invaginations, bench section are a plain film folding of four layer material plates, an end is sealed, the work capacity of sealing when reducing connection with wrapping of piece.

Realize that the object of the invention method is: launching the plane is that regular rectangular shape, its four peripheries are on the plate of material of continuous straight line, make corresponding to the impression of four upright crest lines of casing with corresponding to the impression of the horizontal crest line of casing, and corresponding to two impressions of two upright sides of casing midline; Make all eight corner points of connect box respectively, intersect, become the oblique line impression of miter angle with upright side center line impression with level, vertical crest line impression; The transverse ends of plate of material is linked together, makes again that it is folded into that two upright sides inwardly fold into, after the bench section is a plain film folding of four layer material plates, with stitching, adhesive tape is sticking or technology such as heatsealing is sealed it along the sideline of one end.

The present invention and known expansion plane relatively have following advantage for rectangle, its periphery of rule for the folding osed top cuboid packing chest of continuous straight line:

1, being foldable to the bench section is the plain film that four layer material plates fold, and its width has only the width of a facade of packing chest, and floor area is little, is convenient to deposit, carries, carries.

2, under the state that forms the cuboid packing chest, at one end sealed, in it during empty, can be folded into a plain film; Under the state that is folded into a plain film, when at one end being sealed, can open and form a cuboid packing chest; When packing chest is folded into a plain film or is opened into the state of cuboid by a plain film, will an end seal destruction, easy to use.

3, packing chest can provide use later on an end closure, the work capacity of sealing in the time of can reducing connection with wrapping of piece during fabrication.

Below in conjunction with embodiment and description of drawings structure of the present invention:

Fig. 1 is expansion planar view of the present invention and impression figure.

Fig. 2 forms the scheme drawing of osed top cuboid for the present invention.

Scheme drawing when Fig. 3 does not seal state for the present invention on top.

Fig. 4 is I-I cutaway view of Fig. 2.

Fig. 5 is II-II cutaway view of Fig. 2.

Fig. 6 is folded into the front elevation that the bench section is a plain film folding of four layer material plates for the present invention.

Fig. 7 is the top view of Fig. 6.

Fig. 8 is III-III cutaway view of Fig. 6

Be described further below in conjunction with accompanying drawing:

From accompanying drawing, as can be seen, on plate of material, be shaped on the upright crest line impression (1) that forms packing chest, horizontal crest line impression (2); Impression (1) and impression (2) have constituted facade (11) and upright side (10) of packing chest; On the upright side center line impression (4) is arranged, impression (4) can inwardly fold into upright side when packing chest is folded into a plain film, making packing chest form the bench section is the plain film that four layer material plates fold, and its width only is the width of a facade of packing chest (11); Impression (1), impression (2) have constituted bottom surface, top (12) with sideline (7); Be shaped on and connect all eight corner points (5) of packing chest and upright side center line impression (4) respectively and intersect, and become the oblique line impression (3) of miter angle with impression (1), impression (2), impression (3) and impression (1), impression (2), sideline (7), triangle projective planum (8) and triangle projective planum (9) have been formed, plane (8), plane (9) fold in tank surface when packing chest forms cuboid, under bottom surface, top (12); Formed the part (13) that the plate of material transverse ends is linked together between impression (1) and sideline (6); (14) for sealing the adhesive tape of usefulness; (15) be the intersection point of center line impression (4) and oblique line impression (3).

Claims

1, launching the plane is the rectangle of rule, its four week is the continuous straight line in limit, use paper, cardboard, combination board, paper, plastics, metallic membrane, the composite panel of fibre, plastic flagstone, calcium-plastic board and other plastic blending material plate equal strength, rigidity is better, the folding osed top cuboid packing chest that the folded plate of material of folding is made, launch to have on the plane impression (1) corresponding to the upright crest line of casing, impression (2) corresponding to horizontal crest line, have and horizontal crest line impression (2), upright crest line impression (1) forms miter angle, difference all eight corner points (5) of connect box and eight the oblique line impressions (3) that intersect with upright side center line impression (4), it is characterized in that: two impressions (4) are arranged corresponding to two upright side center lines, be folded under the plain film state, two upright sides of casing inwardly fold into, its bench section is that four layer material plates fold, and the one end is sealed.
