Description

File secrecy Special folding carton

Technical field

The utility model relates to folding type carton technical field more particularly to file secrecy Special folding cartons.

Background technique

Archives refer to the various forms of original notes with value for preservation that people are directly formed in every social activities Record, original record is its essential attribute；The archives of Ancient Times in China have different appellations in each dynasty, such as in the Shang dynasty Referred to as " volume ", be called in the Zhou Dynasty " in ", Qin Han is also referred to as " ancient books and records ", Chinese Wei call later its " document ", " official documents and correspondence ", " official documents or correspondence ", " files ", " book book ", the Qing Dynasty are mostly used " archives " later, are now collectively referred to as " archives ".

Need in many cases by archives from a place be carried to another place (such as company operation place become More), in this case, it will use Special folding carton, this carton is in fully unfolded position when usually (being now in foldable state) can be divided into bottom plate, cover board and four side plates, and mutual junction has a folding line, and when use presses It is holded up according to folding line, is then attached using glue or adhesive plaster, but this folding type carton has certain deficiency, makes When it to be become to cardboard again after, due to the presence of glue or adhesive plaster so that separated between plate between adjacent it is constant, The damage that plate is easily caused when separation can cause it that can not reuse when serious.

Utility model content

Purpose of the utility model is to solve folding type carton in the prior art in use, needing by glue or glue Cloth is fixed, and is not easy to the problem of carton is torn open back to foldable state again after use, and the dedicated folding of file secrecy proposed Stacked carton.

To achieve the goals above, the utility model adopts the technical scheme that

File secrecy Special folding carton, including the cardboard formed under carton fully unfolded position, the cardboard is the bottom of by Plate, the first side plate, the second side plate and upper cover plate composition, two first side plates are symmetrical arranged centered on bottom plate, two institutes It states the second side plate to be symmetrical arranged centered on bottom plate, the upper cover plate is connected with second side plate in left side, the bottom plate and first Side plate connected component, bottom plate and the second side plate connected component and the second side plate and upper cover plate connected component are equipped with a folding Trace, the two sides of two first side plates are symmetrically opened on two second side plates integrally formed with first convex block If the second convex block there are two being integrally formed there are two through-hole, on the upper cover plate, far from bottom plate on two first side plates Side offers card slot.

In above-mentioned file secrecy Special folding carton, the length of first convex block is less than the length of through-hole, institute The width for stating the first convex block is one millimeter bigger than the width of through-hole.

In above-mentioned file secrecy Special folding carton, the length of second convex block is less than the length of card slot, institute The width for stating the second convex block is one millimeter bigger than the width of card slot.

In above-mentioned file secrecy Special folding carton, the bottom plate, the first side plate, the second side plate and upper cover plate are equal It is divided into cardboard outer surface and cardboard inner surface, and is successively arranged waterproof layer, enhancement layer, paper from cardboard outer surface to cardboard inner surface Core and flame-retardant layer.

In above-mentioned file secrecy Special folding carton, the waterproof layer is pasted by multiple waterproof papers.

In above-mentioned file secrecy Special folding carton, the enhancement layer is pasted by multiple U.S. paper jams.

In above-mentioned file secrecy Special folding carton, the flame-retardant layer is pasted by multiple asbestos papers.

Compared with prior art, the utility model advantage is:

1: the fixation between plate and plate is not necessarily to bond without any iron nail or hinge connection, without glue, can after use It is quickly reduced into foldable state, convenient for storage or is carried, so that the folding type carton can be repeatedly used.

2: by setting waterproof layer, enhancement layer and flame-retardant layer, improving the intensity of cardboard, while also improving the anti-of cardboard Fiery waterproof ability.
