Description

Envelope

Technical field

The present invention relates to a kind of envelope, particularly be applicable to direct envelope by printer prints.

Background technology

In the past, envelope beyond prescribed form or the prescribed form, be by a piece of paper by suitable folding forming, so its essential structure must be consistent, middlely pastes, paste the side, to paste various envelopes such as (カマス subsides), rhombus stickup be well-known to straw bag shape.As shown in Figure 1 be to belong to be referred to as the form that straw bag shape is pasted (カマス subsides), a piece of paper folding back stickup, be formed with address face top layer 1, the internal layer 2 of the face of turning back and the flap of an envelope 3 are arranged.This envelope is the envelope of common prescribed form, is to seal A by what top layer 1 side extended out, top layer 1 and internal layer 2 bonding finishing.

, in recent years not only aspect the office and also family also popularized computing machine, also obtained popularization and application widely corresponding to this chopping machine.Follow popularizing of chopping machine, writing also of address printed with chopping machine more.And then, except that writing the address, no matter also be hopeful to print the requirement of addresser's lead stamp, decoration etc. at what position of envelope.

But as shown in Figure 1, existing envelope is three layers at the paper of the part of sealing A, this just with the two-layer difference that on thickness, produced of core.As a result, when envelope passes through roller, produced the gap between the core of printing and the roller, can not print clearly sometimes.In addition, by conveying roller the time, cause fold because the difference of thickness produces the difference of hardness sometimes, print chaotic because the difference of thickness produces the change or the different paragraphs of the photographic fixing degree of China ink.Further, top layer and internal layer be by about seal coincidence, layer is bad with the degree of being close between the layer, and the layer of being carried by driving rolls and create a difference because of slip by the layer that return idler is carried can not smooth transportation and the unfavorable condition of correct printing thereby also may produce.And thickness is different in the part because all seal for aforementioned various well-known envelopes, so produce same unfavorable condition, this unfavorable condition is particularly evident in laser printer especially.

Summary of the invention

The present invention is a purpose to solve above-mentioned existing problem, discloses a kind of structure of envelope, makes it both to be used in also reliable content such as print address of the chopping machine extensively popularized.

In order to achieve the above object, the present invention is converted into two foldings to paper, thereby be formed with the top layer and the internal layer that the face of turning back is arranged of address face, between described top layer and internal layer, be provided with the inclosure zone of opening, between respect to one another of aforementioned top layer and the internal layer, all directly fit in marginal portion except that opening and broken line, top layer and internal layer roughly overlap each other simultaneously, and the aforesaid roughly whole zone in zone of enclosing is by constituting with a piece of paper.

Described envelope is not directly fitted by sealing between top layer and the internal layer, and thickness is even, so can effectively prevent existing owing to the different printings that cause of local thickness are bad, promptly produce fold, perhaps the photographic fixing degree of China ink changes, and perhaps different paragraphs is printed chaotic.In addition and since the degree of being close to of top layer and internal layer with existing compare very good, so even also be difficult to produce dislocation, conveying that can be level and smooth by time between the roller of chopping machine.Further, do not seal because have, be rectangle or near rectangle so launch paper, improved from raw material paper to the yield rate of determining when launching paper.Add, can omit the folding work that seals, make to make and oversimplify.In addition, can open envelope from the side by tearing two aspects in the table.Certainly, because there is not uneven thickness, so especially smooth when writing the address.

On the one hand, for above-mentioned structure, top layer and internal layer roughly overlap, and opening is not easy to enlarge, and under the opening condition of enlarged, the direct bearing load effect in fitting part, this part has the possibility of tearing.For preventing this unfavorable condition, the edge that is preferably in the aforementioned opening of internal layer is provided with breach.

In addition, even, also realize the thickness equalization, can consider to seal the flap of an envelope of enclosing the zone and make the shape that roughly overlaps with internal layer under the state of the flap of an envelope with closure of openings.

On the other hand, if top layer and internal layer shape are identical, because folding precision can produce when bag and overlap dislocation, interior course is one-sided to be deflected away from.Described envelope is when being used for chopping machine, and this part that deflects away from will become obstacle, cause the chopping machine inner card board, perhaps produce the rolling gauffer, can not carry out failure-free and print.In order to prevent this unfavorable condition, both sides on the top layer form internal layer and the flap of an envelope by broken line respectively, when described top layer and internal layer are directly pasted, preferably aforementioned internal layer can be formed from aforementioned broken line or apart from the position of described broken line certain intervals the undercut that fabric width narrows down gradually.

So the internal layer fabric width narrows down gradually from broken line, and when envelope was made, under the situation of broken line folded in half, even a point tolerance is arranged, internal layer can not deflect away from from the top layer yet.

Here " fabric width narrows down gradually " also includes the stepped notion that narrows down of fabric width.

The specific embodiment of invention

Below, the embodiment that the present invention is desirable is described with reference to the accompanying drawings.And, corresponding part among following each embodiment is composed with identical symbol.

The envelope F that this embodiment relates to as expansion drawing (Fig. 2), finish shown in the figure (Fig. 3), launch paper ST and be converted into eighty percent discount, be formed with the top layer 10 and the internal layer 11 of address face, be that the rectangle of enclosing region S is set between top layer 10 and internal layer 11.The broken line 13 that is used to be converted into eighty percent discount constitutes in the mode corresponding to the long leg f1 of envelope F, by being that side f2 engages top layer 10 and internal layer 11 at aforementioned broken line 13 adjacent minor faces, has formed the inclosure region S to opposite side one side opening of aforementioned broken line 13.

On the one hand, the long limit f4 of 10 aforementioned broken line 13 opposite side from the top layer extends the flap of an envelope 12 by second broken line, 14 one, and described the flap of an envelope 12 turns back by aforementioned second broken line 14, the opening 17 of aforementioned inclosure region S can be sealed.

In the present embodiment, mutual aspectant 10b, 11b on the minor face f2 of aforementioned top layer 10 and internal layer 11 are provided with adhesive portion 20 then, thereby at adhesive portion 20 place's coating adhesives etc. are directly fitted in top layer 10 and internal layer 11.Again, though for the inclosure region S is enclosed fully, aforementioned adhesive portion 20 relates to the whole of minor face f2, according to purposes, also not bonding portion can be set in the part of minor face f2.

In addition, in the present embodiment, aforementioned top layer 10 and internal layer 11 are same shape, and in the completion status of envelope F, its top layer 10 and internal layer 11 overlap.

And, existing common envelope, not tight because of considering texture etc. thereby crease, cause the increase of the some degree of thickness of crease part, during many accumulations, compare with opposite side, crease one side protuberance, in the present embodiment, the crease at broken line 13 places is tightr than existing, make the thickness homogeneous, even many overlapping, overlapping envelope F thickness on the whole equates.

According to the embodiment of described structure, the roughly Zone Full of aforementioned inclosure region S is because thickness equates by constituting with a piece of paper, can effectively prevent existing owing to the uneven printing that causes of local thickness is bad, promptly produce fold, the photographic fixing degree of China ink changes, and perhaps different paragraphs is printed chaotic.In addition and since the degree of being close to of top layer 10 and internal layer 11 with existing compare very good, even also be difficult to produce dislocation, conveying that can be level and smooth by time between the roller of chopping machine.Again,,, be deposited on the paper feed frame that paper feed uses and unfavorable condition can not take place, can print continuously, and be easy to keeping, packing because of overlapping envelope F thickness equates even what open overlapping with.Certainly, there is not uneven thickness, especially smooth when writing the address.

From the angle of making, do not seal because have, launch paper ST and be rectangle or near the shape of rectangle, determine the effect of the yield rate when launching paper ST and have raising from raw material paper.Add,, make the effect of oversimplifying so have to make because can omit the folding work that seals.

Fig. 4 be present embodiment envelope F expansion a kind of mode, the 10th, the top layer of address face is arranged, the 11st, the internal layer of the face of turning back is arranged, the 12nd, the flap of an envelope.13, the 14th, the broken line that every envelope F demoulding is provided with when forming simultaneously.Here, though top layer 10 is oblongs accurately, internal layer 11 narrows down gradually and has formed the undercut 15 of taper to opening 17 directions from broken line 13 beginnings.Fig. 5 is illustrated on the structure of Fig. 4 and is converted into eighty percent discount by broken line 13, fits by lining cement in adhesive portion 20 and form the completion status of envelope F in both sides.

For the present invention structure, the technology of particular importance is not to form the consistent oblong in internal layer 11 and top layer 10, but the taper that formation narrows down gradually.If in full accord as first embodiment, as shown in figure 12, because folding error, internal layer 11 will be from the top layer 10 deflects away from, and the shape of the whole F of envelope can take place unpredictable staggered uneven, and the appearance deterioration also can produce situations such as printing is bad sometimes.Yet according to described structure, even produce the staggered of a little when broken line 13 is folded mechanically, internal layer 11 can be from the top layer 10 deflect away from yet.So as long as the shape on top layer 10 is correct, the global shape of envelope F just can not produce mistake, even also way roller paper feed obliquely not when being used in chopping machine, even when many pieces of envelopes are overlapping on the paper feed frame that paper feed is used, also do not deflect away from part, so can solve problem because of the distortion warpage.

Fig. 6 represents the 3rd embodiment, and the initial point of undercut 15 is not from broken line 13, but in the middle of broken line 13 and opening 17, because envelope is that the demoulding forms one by one, is folded mechanically in the part of broken line 13, can not produce excessive error on folding.So consider, even undercut 15 this moment can not prevent to deflect away from from broken line 13 beginnings yet.

Again, as shown in figure 13, in order to obtain the action effect same with the foregoing description, also can make the side f2 of internal layer 11 be step shape, the direction of width to the top of internal layer 11 narrowed down, or as shown in Figure 14, the width setup of internal layer 11 must be than top layer 10 narrow.

The envelope F of present embodiment, as Fig. 7～shown in Figure 9, the both sides that form the long limit f3 of aforementioned opening 17 at internal layer 11 are provided with breach K.The long limit f3 of this concrete breach carries out the cutting of V word and forms, and is arranged on a certain position of adhesive portion 20 inboards.Thus, not only opening 17 enlarges easily, and makes when the thing OB that will pack into packs into or takes out under opening 17 condition of enlarged, and stress just can not act on direct peeling force at the position of aforementioned breach K in aforementioned adhesive portion 20.Even so opening 17 excessively enlarges, from the part generation breach of breach K, fatiscent a little words also can be capped by the flap of an envelope 12 and the bonding of internal layer 11, can avoid enclosing region S can not the sealed-in unfavorable condition.

Again, do not limit size, shape, position of breach K etc. in this form of implementation, breach K also can be only in arbitrary one-sided setting in addition.

For the flap of an envelope 12 with opening 17 osed top states under, thickness also can be impartial, as shown in figure 10, consideration will seal the flap of an envelope 12 of the opening 17 of enclosing the zone, be arranged to and top layer 10 or the internal layer 11 general shapes that overlap.

In addition, among aforesaid each embodiment,, as shown in figure 11, also can make broken line 13 corresponding with short leg f2 though be that the envelope of growing with broken line 13 and the corresponding transverse axis of long leg f1 is that prerequisite is illustrated.But, like this, when using angle bender to make envelope F automatically, will make expansion paper ST elongated, because the restriction on the aforementioned angle bender function, the size of the envelope F that makes is compared the little situation that is limited that just has with the envelope of previous embodiment.

In addition, bonding for top layer and internal layer, yes how can.Further, the present invention is an object with the envelope of finishing not only also, and certainly, object also can be article of being handled the duplex page status of both sides bonding plane by the end user.

, directly fit between the inside edge part of top layer and internal layer to detailed description of the present invention according to above, thickness is even, can effectively prevent existing owing to the uneven printing that causes of local thickness is bad, promptly produce fold, perhaps the photographic fixing degree of China ink changes, and perhaps different paragraphs is printed chaotic.In addition and since the degree of being close to of top layer and internal layer with existing compare very good, even also be difficult to produce by time between the roller of chopping machine staggered uneven, conveying that can be level and smooth.And, do not seal because have, determine yield rate when launching paper so improved from raw material paper, add, can omit the folding work that seals, make to make and oversimplify.In addition, can open envelope from the side by tearing two aspects in the table.Certainly, because there is not uneven thickness, so especially smooth when writing the address.In addition, if internal layer begins or begins width from the position apart from aforementioned broken line certain distance to narrow down gradually from aforementioned broken line, even top layer and internal layer produce folding error when folding by broken line, perhaps when the demoulding, produce some errors, because of having implemented undercut, internal layer just can not deflect away from from side direction, even under the situation of using the printer prints address, can avoid taking place problems such as paperboard, distortion really yet.
