Abstract

The utility model relates to a packaging product, in particular to a plastic packaging box. The structure of the plastic packaging box is special, so as to achieve the effects that the manufacture yield is high, and a bottom plate, a cover plate, an upper ear plate and a lower ear plate are combined and all have low probability of opening or closing. To achieve the purpose of the utility model, the novel plastic packaging box formed by cutting and folding plastic paper comprises four panels; two side plates in the four panels respectively extend on the two sides to form two ear plates; and one of the other two panels extends on the two sides to from the bottom plate and the cover plate. The novel plastic packaging box is characterized in that folding edges are arranged on the forefront edges of the cover plate and the bottom plate; gaps are formed between the cover plate and the corresponding folding edge and between the bottom plate and the corresponding folding edge; and the gaps are buckled with the ear plates. The novel plastic packaging box has high manufacture yield, and can prevent the bottom plate from automatically springing open.

Description

The novel plastic packing box

Technical field

The utility model relates to a kind of packing articles, particularly a kind of plastic packing box.

Background technology

Is plastic packing box also stale in fact, but how he makes? common people do not know, and it is unfolded by plastic paper and forms in fact.In factory's system time spent, can be at cover plate, base plate, cut out with cutter and cut at upper ear plate, lower ear plate place.This large-scale manufacturer, when making, stacking above the capital is thousands of cut, because only in this way just can enhance productivity, exactly because yet also like this, in these thousands of plastics up to a hundred, necessarily have partly not cut to cut and arrive, or cut not thorough because the present practice is: only the folding of cover plate along on cut an osculum, can generation not switch to because put uneven like this, for above-mentioned reasons, when people attempt that plastic flagstone is converted into plastic casing, will produce the existing picture that fractures, the yield rate that this just often says in the industry; For existing plastic casing manufacture craft, in general, do 10,000, in fact we will do 12,000 so, because there is 10% to 20% meeting to be rolled over bad.Also there is a problem in the plastic casing that has technology to make in addition now, and that is exactly that the fastening of working as between cover plate and the upper ear plate usually can be opened unintentionally, and base plate also is the same reason with lower ear plate.Can bring a lot of unnecessary troubles like this, can so how just avoid above-mentioned these technical matterss?

Summary of the invention

The utility model just provides a kind of plastic casing that can solve above-mentioned two large problems, because its special structure, accomplishes to make the yield rate height, and base plate, cover plate combine with last lower ear plate and all be difficult for folding.

For finishing above-mentioned utility model goal of the invention, the utility model is achieved in that a kind of novel plastic packing box, and it is to form by a plastic paper cutting is folding; It is made of four panels, and in described four panels, wherein two side plates extend two otic placodes to both sides respectively; Wherein a panel in other two panels extends a base plate and a cover plate to both sides; It is characterized in that: the place, forefront of described cover plate and base plate is provided with the folding edge; Be provided with breach between folding edge and cover plate, the base plate; This breach and otic placode are interlocked.Owing to be provided with breach between folding edge and cover plate, the base plate, rather than joint-cutting, like this when making, cutter will under a little more deeply, the possibility that is not switched to is just few like this, in addition, when foldable type, by being vacancy, so people are easy to just notice to this part, he has on earth and is not switched to, therefore the possibility that can avoid fractureing like this.

Described cover plate breach front is positioned on the crease line overall U-shaped.

Described upper ear plate integral body is trapezoidal, is being provided with a boss with the cover plate place of connecing, and this boss just is stuck in the indentation, there of cover plate, fastens with the cover plate breach.This engaging can strengthen the stretching dynamics, behind fastening, generally will be deliberately or specially go to draw just and can draw back, otherwise generally can not open automatically; Thereby guaranteed the quality of product.

Described base plate breach front is positioned on the crease line overall U-shaped.

Described lower ear plate integral body is trapezoidal, is being provided with a boss with the base plate place of connecing, and this boss just is stuck in the indentation, there of base plate, fastens with the base plate breach.This scheme is in order to prevent that base plate from can automatically spring open equally.

Skin at plastic casing has also been paid temporary protective film.Can guarantee that in the process of transporting producing plastic casing is not scratched, thereby further guarantee yield rate.

Fig. 1 is a constructional drawing of the present utility model.

In order further structure of the present utility model to be represented to everybody, below we do progressive elaboration to the utility model in conjunction with the accompanying drawings.

[0012] as shown in Figure 1, a kind of novel plastic packing box, it is to form by a plastic paper cutting is folding; It is made of four panels, and in described four panels, wherein two

side plates

11,12 extend two

otic placodes

13,14 to both sides respectively, are respectively upper ear plate 13 and lower ear plate 14; Wherein a panel in other two panels extends a base plate 15 and a cover plate 16 to both sides; The place, forefront of described cover plate 16 and base plate 15 is provided with folding along 17; Folding along 17,18 and cover plate 16, base plate 15 between be provided with breach 19,20; Cover plate 15 breach 19 fronts are positioned on the crease line 21, overall U-shaped, and upper ear plate 13 integral body are trapezoidal, are being provided with a boss 22 with cover plate 16 places of connecing, and this boss 22 just is stuck in breach 19 places of cover plate 16, fastens with cover plate breach 19.Described lower ear plate 14 integral body are trapezoidal, are being provided with a boss with base plate 16 places of connecing, and this boss just is stuck in the indentation, there of base plate, fastens with base plate 15 breach.Breach front on the base plate 15 is positioned on the crease line 23, overall U-shaped.Owing to be not to be to cut single line again on the crease line, but cut out the breach of U-shaped like this, yield rate is greatly enhanced like this; Because the breach of U-shaped matches with boss 22, make fastening between cover plate 16 or base plate 15 and upper ear plate 13 or the lower ear plate 14 apart from increase on the other hand, therefore, fastening is tightr mutually, so difficult more being drawn back.
