Description

Convenient envelope

The utility model belongs to a kind of envelope, and specifically a kind of band is sealed off line formula envelope.

Envelope is a kind of disposable consumption articles for use commonly used, and being worth cheap is one of important requirement, and therefore making simply is the important content that design will be considered.Simultaneously, it is bearing the effect of safety communication, the transmission of protection information again in communication process.Traditional ordinary envelope capable, the outstanding problem of existence are to seal off, and all very easily damage mail in the envelope no matter tear or cut.The design of some band Kaifeng line formula envelopes is arranged at present, started the precedent of envelope reform, as CN86208642, proposition is between envelope body and capping, lay the folding envelope line of one one end bending along broken line, this sweep sticks between envelope and the capping, the remainder adhesion.By this design, because crooked wiring and part adhesion, carrying out Quantity production is the comparison difficulty, and on the other hand, the adhesion fastness on envelope is not strong.Also having a kind of this type of envelope, is to open two row perforations at the contiguous place of wiring, and this has increased one procedure undoubtedly again.Below all stipulated to bury backguy underground at the back cover lid.Envelope opening part particularly, this is the maximum place of contact, it is appropriate inadequately sealing off that line places herein.

The purpose of this utility model provides a kind of opening safety labor-saving, envelope with low cost, and this envelope is easy to process, does not influence the Quantity production of traditional work, so the reason product is novel and increase for its cost.

Implementation method of the present utility model is that the either side (preferably not in open side) in envelope is pasted the fine rule that tension intensity is suitable, and an end of this line is hidden, and the other end reveals slightly, is convenient to open.

Specify below in conjunction with accompanying drawing.

Fig. 1 is one of convenient envelope expansion drawing.

Fig. 2 is two of a convenient envelope expansion drawing.

Referring to Fig. 1, envelope paper 2 is relative with 5 folding, and 1 is relative with 3 folding, forms four folding linear slits, 6 is the envelope face, according to making and different application needs, choosing is arbitrary folding linear slit wherein, and side is pasted the fine rule that certain tension intensity is arranged within it, line keeps straight during stickup, and viscose glue completely, in of line was hidden in, exposed slightly another termination.With three face folded, glued, reserve an opening, the folded seam on this limit is not generally preferably in order to unwrapping wire.In addition, note during wiring the end of a thread not being stayed open end, in order to avoid the user imbeds the end of a thread when envelope is believed.

Referring to Fig. 2, envelope paper 12 is relative with 14 folding, and 11 is relative with 13 folding, and 15 is the envelope face, pastes the Kaifeng line for optional one in four folded seam that are folded to form, as described in sticking line method illustrates as Fig. 1.With the folding involution of three faces, reserve envelope tongue 12 or 14 as opening edge, preferably do not select the folded seam wiring of opening edge.

When opening, hold the end of a thread that exposes and get final product along stitching to draw to cut.

Below be embodiment of the present utility model.

It is folding relatively in twos with four angles to cut square of paper, can form length of side 17cm, and the shandardized envelope of wide 11cm is cut out the little triangle that goes between the adjacent folds angle, as shown in Figure 1, gets length and is the fine rule of 19.5cm, along 3,6 folding dotted line that string pendulum is straight, not crooked.Two the end of a thread one ends do not exceed outside the paper, only have an end to expose, and are convenient to seal off.Equally, by above method, also can be at 2,6 or 5,6 sticking lines, line length is got 13cm, and three limits are coated with glue bond then, stay one side to be open end.The envelope of extended formatting can in kind be made.

The opening line can not need special, utilizes ordinary sewing machine line, and its tension intensity can reach opens requirement.

The utility model also is applicable to the making of other similar paper bag series products.

Claims (4)

1, a kind of convenient envelope that is made of ordinary envelope capable and opening line is characterized in that having in envelope four sides opening line of being convenient to open envelope of an inboard stickup.

2, convenient envelope according to claim 1 is characterized in that sealing off any side of line Pasting in envelope four inboards.

3, convenient envelope according to claim 1 is characterized in that burying underground when sealing off line in envelope one inboard, and the end of a thread one end is hidden, and the other end exposes.
