Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1

Referring to fig. 1-3, a reusable envelope comprises an envelope body 3 and a cover 1, the cover is provided with an opening area 12, the envelope further comprises a second cover 2, the cover 1 is provided with a first identification area 61, the first identification area 61 overlaps the opening area 12, the second cover 2 is arranged on the inner side of the cover 1, the second cover 2 is provided with a first connecting portion 21 and a second connecting portion 22, the inner side of the cover is provided with a sealing glue 13, the sealing glue 13 is arranged on the end portion of the cover 1, a first peeling portion 11 is arranged on the cover 1 corresponding to the second cover, the peeling portion is formed by arranging a cutting line of die cutting on the cover body corresponding to the second cover, a first peeling portion 11 is arranged between the two cutting lines, two sides of the first connecting portion 21 of the second cover are respectively provided with a first connecting portion inner glue 211 and a first connecting portion outer glue 212, the first connecting portion inner glue 211 is pasted with the inner side of the sealing cover 1, the second connecting portion 22 is provided with a second connecting portion inner glue 221, the second connecting portion 22 is detachably pasted with a first peeling portion of the sealing cover through the second connecting portion inner glue 221, the second connecting portion completely falls into the first peeling portion, and the second sealing cover is provided with a second unsealing area 24.

When the envelope is produced, the second cover 2 is respectively pasted with the cover inner side through the first connecting part inner glue 211 and the second connecting part inner glue 221, the first connecting part inner glue 211 is pasted with the cover inner side, the second connecting part inner glue 221 is pasted with the first peeling part 11 of the cover 1 in a separable mode, and the second connecting part 22 is completely fallen into the first peeling part 11.

When the envelope is used for the first time, the sealing glue 13 on the sealing cover 1 and the release paper on the first connecting part outer glue 212 are peeled off firstly, then the sealing glue 13 and the first connecting part outer glue 212 are pasted with the envelope body 3, the sealing glue 13 and the first connecting part outer glue 212 are fixedly pasted with the envelope body 3, a complete sealed envelope is formed, the first identification code 61 is scanned again after a letter cover sheet is scanned and recorded in a mailing process, information such as 'the envelope is used for the first time' and the like is recorded in express tracking information after the first identification code is scanned, the opening area 12 is opened by a receiver, the first identification code 61 can be damaged by the opened opening area, secondary scanning cannot be carried out, after a file in the envelope body is taken out, if only the envelope 12 is damaged, the envelope can be used for the second time.

When the envelope is used for the second time, the document is put into the envelope bag from the opening area 12, then the first peeling part 11 is completely peeled off from the cover 1 through the die cutting line, at this time, the second cover 2 is exposed, because the release layer is arranged between the second connecting part inner glue 221 and the first peeling part 11, the two parts can be pasted separately, therefore, when the first peeling part 11 is peeled off, the second connecting part inner glue 221 is left on the second connecting part 22, the second cover 2 is folded towards the opening area 12 through the folding part 23, the second connecting part inner glue 221 is pasted with the residual part 14 of the cover 1, the opening area 12 is completely covered in the second cover 2, at this time, the first identification code is also completely or partially covered, at this time, the second identification code 62 is exposed, because the first connecting part outer glue 212 is pasted with the envelope body fixedly, at this time, no damage is needed, therefore, the envelope body 3, the first connecting part 21, the second sealing cover 2 and the residual part 14 of the sealing cover form a complete envelope for secondary use again, when a mail is sent, the second identification code 62 is scanned when an express bill is scanned, the prompt that the envelope is the envelope for secondary use is received in express tracking information, when the envelope is unsealed for the second time, the second unsealing area 24 on the second sealing cover 2 is peeled off, the file in the envelope bag can be taken out, the first connecting part outer glue 212 and the sealing glue 13 can also be covered by the same piece of release paper, only one piece of the first connecting part outer glue and the sealing glue 13 need to be peeled off in the peeling process, the peeling mode is the same as that of the existing envelope, and the peeling process does not need to be added.

The advantages of this embodiment are:

1. the second cover 2 is provided inside the cover 1, and is identical to an existing envelope in appearance.

2. The second cover is low in cost, and the secondary cover is only a strip which is as wide as the existing envelope and is about 2CM wide, so that the cost is very low.

3. The use is convenient, and when the secondary use is carried out, the second sealing cover can be exposed only by peeling the first peeling part 11, which is as convenient as the release paper is peeled off when the primary use is carried out.

4. The safety is high, the second use involves the safety problem of the file transmission process, therefore, the transmission of the file passes through at least three links, the first is the sender, the second is the logistics party, the third is the receiver, in order to guarantee the safety of the file, the receiver must clearly show whether the envelope received is opened midway, therefore, the scheme can clearly display whether the envelope is opened midway, for example; when the envelope is received, the opening area 12 is complete, indicating that the envelope is secure; if the envelope is the envelope used for the second time, the information that the envelope is the envelope used for the second time is received to confirm whether the envelope is the envelope used for the second time, if the envelope used for the second time is the envelope used for the second time, the document is safe, if the envelope not used for the second time, whether the logistics company is opened midway can be traced, the logistics company can be used for the second time, and a person in charge can be found.

5. Because set up first identifying code 61 and second identifying code 62, first identifying code can be destroyed after the first opening a seal to, first identifying code and second identifying code can not appear simultaneously, can avoid the information mistake of secondary identifying code to record, and the recipient can receive this envelope and be the prompt message of first use or secondary use when the addressee, consequently, the circumstances that the responsibility is unclear when preventing the mail in the transmission course and going wrong takes place.
