SUMMERY OF THE UTILITY MODEL

To the circumstances, for overcoming prior art's defect, the utility model provides a plain type big envelope, the effectual big envelope of having solved among the prior art is heavier, and the structure is more loaded down with trivial details, does not have protection facility because of inside, can appear the material and scratch, the fold or the condition of making dirty, and the material needs to be placed in the big envelope of corresponding size according to its size simultaneously, and the size has the restriction, can not place the problem of many materials at will.

In order to achieve the above object, the utility model provides a following technical scheme: including mainboard, first curb plate and second curb plate, the integrative punching press of one side of mainboard has first curb plate, and the integrative punching press of opposite side of mainboard has the second curb plate, all is provided with the line ball between first curb plate, second curb plate and the mainboard, and transparent plastic film is installed to the inboard of mainboard, and transparent plastic film mutually perpendicular's both sides all are provided with the corner, and the corner is for bonding with the connected mode of mainboard, and the surface of second curb plate is provided with the buckle.

Preferably, the thickness of the transparent plastic film is between 0.01mm and 1 mm.

Preferably, the main plate, the first side plate and the second side plate are all members made of a paperboard material.

The utility model discloses at first card paper punching press forms mainboard, first curb plate and second curb plate, and its every square meter's quality is between 200g-400g, simple structure, makes the weight of whole big envelope reduce, and convenient to carry secondly through transparent plastic film, can fix and protect the material, avoids the material to appear scratching, fold or the condition of making dirty, passes through transparent plastic film simultaneously, makes the size range who places the material enlarge, and the limitation reduces, can place many materials at will.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying fig. 1-2.

In the first embodiment, as shown in fig. 1 and 2, the utility model comprises a main board 1, a first side board 2 and a second side board 3, wherein the first side board 2 is integrally stamped on one side of the main board 1, the second side board 3 is integrally stamped on the other side of the main board 1, pressing lines 4 are arranged between the first side board 2, the second side board 3 and the main board 1, a transparent plastic film 5 is arranged on the inner side of the main board 1, two mutually perpendicular sides of the transparent plastic film 5 are respectively provided with a corner 6, the corner 6 is connected with the main board 1 in an adhesive manner, a buckle 7 is arranged on the surface of the second side board 3, the main board 1, the first side board 2 and the second side board 3 are formed by punching a card paper, the structure is simple, the first side board 2 and the second side board 3 are folded along the pressing lines 4, the main board 1, the first side board 2 and the second side board 3 are all members made of a card paper, make the weight of whole big envelope reduce, it is convenient to carry, then 5 mutually perpendicular's of transparent plastic film both sides all are provided with corner 6, fold two corner 6 toward the inside, the rubberizing glues in mainboard 1's top, confirm firm back, alright lift the one side that does not have corner 6, clamp the material between mainboard 1 and transparent plastic film 5, can fix and protect the material like this, avoid the material to scratch the appearance, the fold or the condition of making dirty, simultaneously through transparent plastic film 5, make the size range who places the material expand, the limitation reduces, can place many materials at will, at last with one side clamp of first curb plate 2 between buckle 7 and second curb plate can, improve holistic fastness.

In the second embodiment, the thickness of the transparent plastic film 5 is 0.01mm to 1mm based on the first embodiment, so that the material is protected and the overall aesthetic degree can be improved.
