Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-14, a traceless housing, comprising: the file cover 1, the first supporting plate 2, the second supporting plate 3 and the cover 4 are distributed from top to bottom, wherein the first supporting plate and the second supporting plate 3 are arranged side by side on the same horizontal plane; the edges of two ends of the surface of the first supporting plate 2 are provided with a first groove 21 and a first concave hole 22; a third magnet button 231 is embedded or glued in a third concave hole 23 on the side of the first groove 21; a first magnet buckle 221 is glued in the first concave hole 22; the edges of two ends of the surface of the second support plate 3 are provided with a second groove 31 and a second concave hole 32; a fourth magnet button 331 is embedded or glued in a fourth concave hole 33 on the side of the second groove 31; a second magnet button 321 is glued in the second concave hole 32; the first panel 11 and the second panel 12 of the file cover 1 are overlapped up and down, and the edges are sealed and connected by three edges to form an open bag structure; at least one opening is reserved above or on the left side or the right side of the file cover 1; paper and file data are placed in the bag of the file cover 1; after the first supporting plate 2 and the second supporting plate 3 are folded in half, the folded edges of the paper and the file data are arc-shaped surfaces without folds.

Specifically, when the whole casing is unfolded, the first support plate 2 and the second support plate 3 are arranged on the same horizontal plane side by side, the file cover 1 is glued on the inner surfaces of the first support plate 2 and the second support plate 3, and the cover 4 is glued on the outer surfaces of the first support plate 2 and the second support plate 3 and the side edges of the outer surfaces. The second panel 12 in the envelope 1 is adhesively bonded or thermally fused to the inner surfaces of the first support plate 2 and the second support plate 3 which are adjacently disposed. The first panel 11 and the second panel 12 in the envelope 1 are connected by a three-edge seal whose edges are fused by hot melting or by gluing. One side of the file cover 1, which is left between the first panel 11 and the second panel 12, is open, and the file cover is not sealed. The opening is used for taking and placing paper and file data and is distributed above the file cover 1 or on the left side or the right side. The first panel 11 and the second panel 12 are divided into: flexible plastic panels and thickened plastic films. The first panel 11 is a transparent flexible panel or a transparent plastic film. The second panel 12 is a transparent, translucent, opaque flexible panel or a transparent, translucent, opaque plastic film.

When the shell is folded and closed, the first supporting plate 2 and the second supporting plate 3 are mutually overlapped and arranged and mutually attached. At this time, the first and second grooves 21 and 31 form a closed space between the first and second support plates 2 and 3. The folded envelope 1 is overlapped and attached to a flat surface between the first support plate 2 and the second support plate 3. The folded edge of envelope 1 is unfolded in first groove 21 and second groove 31 to form an arc surface of an approximate circular arc. The hollow areas of the first and second grooves 21, 31 provide a space for the folding edges of the envelope 1 to extend. After the file cover 1 is folded, the file cover does not bend 180 degrees, and thus the folding line is not easy to generate. Thereby ensuring that paper materials such as certificates, awards, business licenses, document materials and the like in the envelope 1 can not generate creases in the folding process.

Specifically, the surface of the first support plate 2 is provided with a first elongated groove 21, and the surface of the second support plate 3 is provided with a second elongated groove 31. The outer surfaces of the first supporting plate 2 and the second supporting plate 3 and two adjacent side edges of the first groove 21 and the second groove 31 are glued or sleeved with a cover 4. The purpose of the first groove 21 and the second groove 31 is to make the folded edge of the paper or the document after folding be an arc surface instead of an edge close to 180 degrees after folding the two shells in half, so as to prevent the folded edge of the paper or the document from generating a crease after bending.

In the process of unfolding the first support plate 2 and the second support plate 3, the four edges of the first groove 21 and the second groove 31 are located on the same horizontal plane and distributed, and the two adjacent sides of the first groove 21 and the second groove 31 support the envelope 1. Meanwhile, the first support plate 2 and the second support plate 3 also support the envelope 1 over a large area.

In the process of folding the first support plate 2 and the second support plate 3 in half, the four edges of the first groove 21 and the second groove 31 are overlapped and attached to each other, and after the first groove 21 and the second groove 31 are folded in half, a sealed space with a cavity structure is formed. The sealed space is used for unfolding the file cover 1 and the paper and the file data inside the file cover, so that the file cover 1 and the folded edges of the paper and the file data inside the file cover form an arc-shaped surface structure. Preventing the generation of creases.

Specifically, first concave holes 22 are distributed on one side of the edge of the surface of the first supporting plate 2, and first magnet buttons 221 are glued in the first concave holes 22. A second concave hole 32 is distributed on one side of the surface edge of the second supporting plate 3, and a second magnet button 321 is glued in the second concave hole 32.

After the first supporting plate 2 and the second supporting plate 3 in the shell are folded in half, the first supporting plate 2 and the second supporting plate 3 are arranged in an overlapped mode, the first magnet buttons 221 and the second magnet buttons 321 on the surfaces of the first supporting plate 2 and the second supporting plate 3 attract each other, and the first supporting plate 2 and the second supporting plate 3 after being folded are connected in a tight fit mode.

The side edge of the first supporting plate 2, which is positioned at the first groove 21, is provided with a third concave hole 23, and a third magnet button 231 is glued in the third concave hole 23. Further comprising: the third magnet holder 231 is embedded inside the side of the first groove 21. A fourth concave hole 33 is formed in the side edge, located on the second groove 31, of the second support plate 3, and a fourth magnet buckle 331 is connected to the fourth concave hole 33. Further comprising: the fourth magnet holder 331 is inserted into the side of the first recess 21.

Wherein, when the first supporting plate 2 and the second supporting plate 3 in the casing are wholly unfolded, the third magnet button 231 at the side of the first supporting plate 2 and the fourth magnet button 331 at the side of the second supporting plate 3 attract each other, so that the unfolded first supporting plate 2 and the unfolded second supporting plate 3 are more smoothly positioned on the same horizontal plane. The third and fourth magnet clasps 231 and 331 may not be provided as needed.

After the first magnet fastener 221, the second magnet fastener 321, the third magnet fastener 231 and the fourth magnet fastener 331 are embedded into or adhesively connected with the first support plate 2 and the second support plate 3, the whole surfaces of the first support plate 2 and the second support plate 3 are plane.

Specifically, after the first support plate 2 and the second support plate 3 are folded in half, the first groove 21 and the second groove 31 which are adjacently distributed after being overlapped form a sealed space. At this time, the first support plate 2 and the second support plate 3 are in a state of being bonded to each other. Since the first panel 11 and the second panel 12 are transparent flexible panels or thickened films, the first panel 11 and the second panel 12 can be bent and folded in half. After the first panel 11 and the second panel 12 are bent and folded, the folded edges of the first panel 11 and the second panel 12 are integrally an arc-shaped surface and are distributed in the closed space formed by combining the first groove 21 and the second groove 31.

Because the first panel 11 and the second panel 12 in the file cover 1 are bent to be approximately arc-shaped surfaces, the folded edges of the certificates, the papers and the file materials clamped therein are also folded edges of the arc-shaped surfaces. Therefore, the paper cannot be folded into two and then the folded edge does not generate crease. When the paper is unfolded again, the paper is still a complete paper without creases. Because first panel 11, paper, second panel 12 are laminated each other, in the fifty percent discount in-process, first panel 11 and second panel 12 among the file cover 1 can produce the clamp force of a front and back two sides to the paper, let the paper in-process of buckling, can not or the at utmost prevent that the hem of paper from producing the crease.

Specifically, the sheets of paper having different thicknesses are placed in the envelope 1, the thicknesses of the first panel 11 and the second panel 12 are different, and the supporting force obtained by the sheets of paper in the envelope 1 is also different. The thicker the paper sheets to be contained in the envelope 1, the greater the hardness, and the thicker the thickness of the first and second panels 11, 12. For thicker sheets, the first panel 11 and the second panel 12 are flexible plastic panels, such as: the flexible panel is made of acrylic materials or other transparent high polymer materials. The paper is clamped between the first panel 11 and the second panel 12, so that the paper is better supported, and the anti-wrinkling performance is better. It is suitable for use in relatively thick paper such as business license. When the envelope 1 is unfolded by using the flexible plastic panels, the flatness of the first panel 11 and the second panel 12, which are relatively thick, is better, so that the display effect of the documents in the envelope 1 is better. When the paper contained in the envelope 1 is thin, the first panel 11 and the second panel 12 may be made of plastic films having a small thickness, so that the purpose of preventing the paper from being folded can be achieved.

According to the requirement, the structure of the first panel 11 and the second panel 12 in the file envelope 1 is not arranged, and paper and document materials can be directly glued on the inner surfaces of the first supporting plate 2 and the second supporting plate 3. The paper is bent in the first and second grooves 21 and 31 without a crease. The outer surfaces of the first support plate 2 and the second support plate 3 are glued with a cover 4. Or, the transparent first panel 11 or the transparent plastic film in the envelope 1 is directly glued to the inner surface edges of the first support plate 2 and the second support plate 3, and the cover 4 is glued to the outer surfaces of the first support plate 2 and the second support plate 3.

Specifically, the inner heights of the first and second grooves 21 and 31 are adjusted by setting the thicknesses of the first and second support plates 2 and 3. The envelope 1 and the paper are bent to obtain different radian curves. When the thickness of the side edges of the first support plate 2 and the second support plate 3 is larger, the space inside the first groove 21 and the second groove 31 after being folded and overlapped is higher, and the radian of the first panel 11, the paper and the second panel 12 is larger. The greater the arc of the fold of the paper in envelope 1, the less likely the paper will be creased. Conversely, the greater the likelihood of a crease in the sheet.

Besides, the widths of the first groove 21 and the second groove 31 can be adjusted, so that the folded edges of the first panel 11, the folded paper and the second panel 12 have longer space for bending. The space for integrally forming the arc-shaped surfaces of the first panel 11, the paper and the second panel 12 is more and longer, and the effect of preventing the paper from folding to generate wrinkles is better.

And when the first support plate 2 is provided with a circle of raised first annular edge, the first annular edge is smaller than the inner diameter of the second groove 31 in the second support plate 3. When the first supporting plate 2 and the second supporting plate 3 are folded, the first ring edge is clamped in the second groove 31 of the second supporting plate 3, so that the buckling effect between the first supporting plate 2 and the second supporting plate 3 is realized. Or the first supporting plate 2 is provided with a circle of convex first annular edge, and the second supporting plate 3 is provided with a circle of convex second annular edge. The first annular edge and the second annular edge are distributed in a staggered manner and are connected in a clamping manner.

As shown in fig. 14, in particular, the edge of the first support plate 2 is provided with a ring of convex first annular edge, and the edge of the second support plate 3 is provided with a ring of convex second annular edge. After the first supporting plate 2 and the second supporting plate 3 are folded in half, the first annular edge and the second annular edge are connected in an overlapping mode. The inner space of the first recess 21 in the first support plate 2 and the second recess 31 in the second support plate 3 is made larger. Thus, a plurality of overlapping envelopes 1 can be arranged on the inner surface of the first support plate 2 and the second support plate 3 to contain more paper or document material.
