(1) when the disassemble cover face 10 ' and the openend at the cover end 20 ', its stress mainly concentrates on connecing place, angle and cover face 10 ' and overlapping the end 20 ' connecting place of openend and pressing edge 30 ', and since pressing edge 30 ' with the hot pressing moulding, be not integrative-structure, be easy to be torn, cause the damage of Document folio, therefore, must be very careful when using this kind Document folio, service life of Document folio is seriously shortened in the careless slightly breakage that promptly can cause Document folio.

(2) because cover face 10 ' and the cover ends 20 ' two adjacent edge form blind end; two adjacent edges are openend in addition; and openend there is no other protection structure; therefore file places Document folio; there is no suitable placing restrictions at openend; get when putting Document folio; because fail to seal the openend of Document folio, file is easy to be skidded off by openend, cause the loss of file or stained; when Document folio places in suitcase or leather trunk; rock slightly, file is wherein also very easily deviate from Document folio, and causes the situation of losing or polluting file; use rather inconvenience; therefore, the file that this Document folio storEd is worth, and mostly belongs to general file; for the file that more senior needs are properly preserved, do not preserve mostly with this file condom envelope.

Because the above-mentioned deficiency of existing file cover, the purpose of this utility model promptly is to provide a kind of Document folio of improvement, and file is packed into behind the Document folio, can make file obtain safe protection positively with the openend sealing.

Primary structure improvement of the present utility model is, close the adjacent opening edge of edge at cover face and cover base pressure with Document folio, the commissura of a bit of length is set simultaneously in the pressing of pressing edge, cooperate cramp and the button of being located at another opening edge, can really the file envelope be placed Document folio inside, unlikely drop out in outside, reach the purpose of protected file; The making processing of cramp and catching groove can be carried out during the end simultaneously in hot pressing trap face and cover; In addition, in the nearly commissura of cover face place, be parallel to commissura and establish the groove of turning back, so make to start the cover face and get when putting file, the stress of cover face bending concentrates on the groove place that turns back fully, and is not concentrated in the commissura place, can guarantee that commissura is intact, effectively the service life of file lengthen cover.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.

Fig. 1 is the still untight schematic perspective view of the utility model openend;

Fig. 2 for the utility model cover face, the cover end by the generalized section of cramp and catching groove fastening the cut-away view of 2-2 line among Fig. 3 (promptly along);

Fig. 3 is for shielding and sustain the schematic perspective view of file after the utility model openend sealing;

Fig. 4 is the utility model cover face stressed action schematic diagram of groove of turning back when raising;

Fig. 5 is a stereo appearance figure of commonly using Document folio.

See also shown in Figure 1, the utility model agent structure is to commonly use Document folio similar, it is a whole semi-transparent plastic film body, be folded to form the cover face 10 and the cover end 20 that side links to each other, adjacent one side, limit linked to each other with the cover face 10 and the cover end 20, also become pressing edge 30 with the hot pressing crimping, feature of the present utility model then is the structure that can close the Document folio internal file of cover face 10 and the cover ends 20 openend setting, and the setting of the commissura and the groove of turning back.
