Abstract
The utility model relates to the technical field of envelope, especially a kind of pleat-free envelope, there is rectangular envelope body, the unsealed position place of described envelope body is provided with self-adhering type edge sealing, envelope body is double-decker, envelope body is formed primarily of anti-folding inner plastic and outer layer of kraft paper, and the outer rim of envelope body is provided with endless metal bound edge.The fracture resistance of this envelope is strong, can ensure the planeness of its inner mail.
Description
Technical field
The utility model relates to the technical field of envelope, especially a kind of pleat-free envelope.
Background technology
Envelope is mainly used in postal delivery mail, conservative communications content, and it is a kind of bag-shaped device of intercommunion document information, generally makes rectangular paper bag.But, existing most envelope comes with some shortcomings part on structure design, cause envelope in delivery process, occur the phenomenon of fold, the phenomenon of mail breakage in envelope is even there will be time serious, also not very very serious for general correspondence problem, but for some special mails, as in envelope being the article mail with magnetic stripe, then very large trouble can be brought to addressee.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provides a kind of pleat-free envelope keeping mail planeness.
The utility model solves the technical scheme that its technical matters adopts: a kind of pleat-free envelope, there is rectangular envelope body, the unsealed position place of described envelope body is provided with self-adhering type edge sealing, envelope body is double-decker, envelope body is formed primarily of anti-folding inner plastic and outer layer of kraft paper, and the outer rim of envelope body is provided with endless metal bound edge.
Further restriction, in order to improve the sealing effectiveness of envelope further, therefore the endless metal bound edge described in technique scheme is provided with the magnetic adhesion assembly being positioned at self-adhering type edge sealing fold line place.
Further restriction, magnetic adhesion assembly described in technique scheme comprises two and to be positioned at above self-adhering type edge sealing fold line and symmetrically arranged upper magnet and two to be positioned at below self-adhering type edge sealing fold line and symmetrically arranged lower magnet, and described two upper magnet attract each other with two lower magnets respectively.
Further restriction, in order to reduce the manufacturing cost of envelope, therefore the anti-folding inner plastic described in technique scheme is made up of organism glass.
Further restriction, in order to avoid the corner scratch foreign object of endless metal bound edge, therefore four cornerite places of the endless metal bound edge described in technique scheme are equipped with rounding.
The beneficial effects of the utility model are: a kind of pleat-free envelope of the present utility model, envelope body adopts the double-decker be made up of anti-folding inner plastic and outer layer of kraft paper, and in the outer rim of envelope body, endless metal bound edge is set, envelope body and endless metal bound edge form rigid construction between the two, effectively prevent the phenomenon that fold appears in envelope, and then ensure the planeness of mail in envelope.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, envelope body, 11, anti-folding inner plastic, 12, outer layer of kraft paper, 2, self-adhering type edge sealing, 21, fold line, 3, endless metal bound edge, 4, magnetic adhesion assembly, 41, upper magnet, 42, lower magnet.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of pleat-free envelope of the utility model as shown in Figure 1, there is rectangular envelope body 1, the unsealed position place of envelope body 1 is provided with self-adhering type edge sealing 2, envelope body 1 is double-decker, envelope body 1 is formed primarily of anti-folding inner plastic 11 and outer layer of kraft paper 12, the outer rim of envelope body 1 is provided with endless metal bound edge 3, endless metal bound edge 3 is provided with the magnetic adhesion assembly 4 being positioned at self-adhering type edge sealing 2 fold line 21 place, magnetic adhesion assembly 4 comprises two and to be positioned at above self-adhering type edge sealing 2 fold line 21 and symmetrically arranged upper magnet 41 and two to be positioned at below self-adhering type edge sealing 2 fold line 21 and symmetrically arranged lower magnet 42, two upper magnet 41 attract each other with two lower magnets 42 respectively.Anti-folding inner plastic 11 is made up of organism glass.Four cornerite places of endless metal bound edge 3 are equipped with rounding.
When mail is placed on after in envelope, by self-adhering type edge sealing 2 along fold line 21 doubling, opening mouth by envelope is tamping, on two in the process of self-adhering type edge sealing 2 doubling also above Foldable line 21, magnet 41 holds two lower magnets 42 below fold line 21, further enhances the sealing property of envelope opening mouth.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
