Description

folder

The invention relates to an office article, and more particularly to a folder.

The folder is dedicated to the entire page, the main purpose is to better save the file, so that it is neat and standardized. A folder is a tool used for the storage, protection and standard management of paper files during business or business activities. In modern business activities, it is also a function of image display, which can be used to hold various types of paper documents. , but not limited to this. Materials include PP, PVC, cardboard; some are imitation leather, cloth and so on. What is available in the market is usually the standard A4 file. The folder includes a cover and a back cover of substantially the same size, wherein there are two crease lines between the cover and the back cover to form a back ridge between the cover and the back cover.

The object of the present invention is to provide a folder, which is provided with a sealing strip on the back cover of one side of the folder, a slit is formed on the cover to form a corner, the corner is inserted into the sealing strip, and the other side is provided with a crimping line to complete the file. The placement will not fall out when the folder opening is facing down.

A folder having a front cover and a back cover, wherein the cover and the middle of the cover are provided with a middle crease line, and the cover is provided with a sealing strip near the corner of the opening on the side of the cover, the sealing strip is a trapezoidal piece The upper surface of the trapezoidal sheet is close to the corner of the back cover, and the two sides of the trapezoidal sheet are perpendicular to each other. The two waists of the trapezoidal sheet are fixed at the two sides of the back cover to be fixed on the back cover to form two sealing lines. An opening line parallel to the upper surface of the trapezoidal sheet is disposed at a central portion of the trapezoidal sheet, and a first slit is formed between the bottom of the trapezoidal sheet and the waist of the trapezoidal sheet, and the first slit is connected to the trapezoidal sheet The waist is vertical and the cover is provided with two second slits such that the angle formed between the two second slits can be inserted into the open line.

Preferably, the second slit is L-shaped.

Preferably, each of the middle crease lines is provided with a crease line parallel to the middle crease line to form a ridge between the cover and the back cover.

Preferably, the two crease lines are symmetrical with respect to the middle crease line, and a circular chamfer is provided between the middle crease line edge and the two edges of the crease line.

Preferably, two of the sealing lines are made by ultrasonic molding.

Preferably, a crimp line is disposed between the cover and the back cover, and the crimp line and the second slit are respectively located at two ends of the open line of the back cover.

Preferably, the bead line is linear or L-shaped.

Preferably, the crimping line is linearly formed, and the bending extension of the cover is hot-pressed on the back of the cover after the cover is bent in a direction opposite to the first slit to extend to the side of the cover. Made from the side of the cover.

Preferably, the cover and the side edge of the back cover are provided with a plurality of buckles, and the distance between the buckle and the middle crease line is slightly larger than the width of the A4 paper.

Preferably, the shackle is round, square or elliptical for easy returning to the large gear box/box.

The invention has the advantages that: after the file is placed in the folder, since one side of the folder is provided with a crimping line, on the other side of the folder, a corner formed by the two second slits on the cover is formed. Inserted into the sealing strip, that is, the placement of the file is completed, the design is simple, and the utility model can be used for the customized folder service, and is convenient to use, and is more suitable for the ordinary people to use the feel and habit, and the folder opening is opened without using the clamping object. Under the file, the file will not fall out. At the same time, because two crease lines are arranged on both sides of the crease line, the file can be placed thicker, and the middle crease line and the crease line are rounded. The hand is not scratched, and since the distance between the circular shackle and the middle crease line is slightly larger than the width of the A4 paper, the A4 paper file is placed, the moving space is not too large, and the user experience is good. More adapt to market demand.
