In order to solve the technical problem, the utility model discloses a technical scheme be:

the utility model provides a folder, is including the folder main part that is equipped with the intermediate layer, folder main part one side is equipped with the opening, and this opening part is equipped with the arc kink, presss from both sides intraformational paper and can stretch out through the opening to it is crooked through the arc kink.

The outer surface of the folder body is provided with a clamp used for clamping paper.

The cross section of the folder body is U-shaped or Contraband-shaped.

The folder body is provided with a protective film.

An opening structure is arranged on the other side of the folder body.

The folder body and the adjacent other side of one side provided with the opening are provided with opening structures.

Compared with the prior art, the utility model, the beneficial effect who has is:

the A3 paper can be stored in a folding mode through the arrangement of the interlayer and the arrangement of the arc-shaped bending part; because the paper can be guaranteed to be in the bending state by the arrangement of the arc-shaped bending part, the generation of creases can be reduced or avoided.

The folder body is provided with a clip, and the A4 paper can be clamped by the clip, so that the A3 paper is folded around the A4 paper. So that the A3 paper and the A4 paper can be stored.

Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention

As shown in figures 1 and 2, the folder comprises a folder body 1 provided with an interlayer, wherein an opening 2 is formed in one side of the folder body 1, an arc-shaped bent part 3 is arranged at the position of the opening 2, and paper in the interlayer can stretch out through the opening 2 and is bent through the arc-shaped bent part 3. Of course, it is also possible to insert paper into the interlayer through the opening 2 or to withdraw paper through the opening 2.

The size of the folder body 1 can be set according to actual conditions, and if A3 paper is to be stored, the size can be set to be A4; the a3 sheet is placed in the sandwich with half of the sheet protruding through the opening 2 and the protruding part bent by the curved fold 3. Namely, the A3 paper can be contained in the capacity of A4 paper, and the A3 paper folded in half can be protected from being folded by the curved radian formed by the arc-shaped folding part.

As shown in fig. 3 to 5, the folder body 1 includes four side surfaces, at least one of which is provided with an opening 2 (i.e., the opening 2 is provided with an arc-shaped bent portion 3), and any one or two of the remaining three surfaces may also be provided with an opening structure (i.e., no side surface is provided). For the sake of clarity, the curved fold 3 is not shown in fig. 3 to 5; wherein, fig. 4 is a schematic view of the other side having an opening structure; FIG. 5 is a schematic view of the remaining two sides having openings.

For convenience of description, four sides of the folder body 1 are named: upper side, lower side, left side and right side. For example: when the opening 2 of the arc-shaped bent portion 3 is located on the left side, that is, any one or two of the upper side, the lower side and the right side may be configured as an opening structure.

Preferably, the folder body 1 is provided with an opening structure at the other side adjacent to the side provided with the opening 2. When the opening 2 of the curved bent portion 3 is located at the left side, the adjacent other side is referred to as the upper side or the lower side.

As shown in fig. 6 and 7, further, the outer surface of the folder body 1 is provided with a clip 4. The excess of the a4 paper and/or the A3 paper can be held by the clamp 4. The clamp 4 can adopt a structure in the prior art

Preferably, the sectional shape of the folder body 1 is "U" or "Contraband".

Further, a protective film 5 is provided on the folder body 1.

The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
