[0002]
[Prior art]
2. Description of the Related Art Conventionally, in order to eliminate stains and damages on covers such as notebooks and books, notebook covers that cover and protect the surface of the covers are made of synthetic resin sheets.
As this type of cover, there is known a cover in which a card and other various portable articles can be mounted or stored for the convenience of the user. For example, in a notebook cover, a support piece for inserting and holding a notebook cover is provided, and further a paper-like body storage part for inserting and storing a cash card or a telephone card and a bag-like pocket part for storing thick parts are provided. It has been known. In particular, as the pocket portion, for example, in order to accommodate a thick part, a pocket portion serving as a partitioning piece is provided at the peripheral portion of the pocket portion so as to have a space in the thickness direction, thereby forming a pocket portion that swells in three dimensions. It is known.
[0003]
[Problems to be solved by the invention]
However, the conventional pocket portion with a hook piece is complicated to manufacture. Particularly, in the work of fusing, welding or cutting with a crimping means such as a hot stamping die or a high frequency welder by a synthetic resin sheet of polyvinyl chloride or polyolefin. In addition to adding the folding process to the formation of the piece, it is difficult to flatten the welding process, so it takes a lot of work, the work is complicated, the productivity is not improved, the shape is not well adjusted, and the formability is poor In addition to high costs, it is not easy to ensure safety in thermal processing work by fusing and welding, and there are problems.
In the present invention, these conventional disadvantages are easily eliminated, and the pocket portion with the scissors provided in the notebook cover or the like is provided in the cover main body with good shapeability, high strength and low cost by plane processing. The purpose of the present invention is to provide a cover for a notebook or the like in a simple and inexpensive form, which can easily set processing conditions during welding of a synthetic resin sheet and has high safety in processing.
[0004]
[Means for Solving the Problems]

[0005]
Further, in the feature of the present invention, a support piece made of a synthetic resin sheet is opened on the inner side of at least one inner surface of a cover body of a rectangular synthetic resin sheet in which front and back covers are continuously formed on both sides of the spine, and the other side A step of fixing the outer edge portion to the outer edge of the cover body so as to overlap each other, and a step of welding and deploying a pocket portion capable of storing a thick article by a storage portion piece made of a synthetic resin sheet on the other inner surface of the cover body. In the method for manufacturing a notebook cover or the like, two synthetic resin sheets each having a flange piece that can be bent in the thickness direction on three sides of the rectangular storage part piece are laminated and laminated. The overlapping edge is welded to form a pocket portion, and the lower resin sheet of the storage portion piece of the pocket portion is fixedly disposed on the inner surface of the cover of the cover body by a welding jig.
[0006]
In the invention of claim 1, the pocket part with the scissors provided in the notebook cover or the like has a rectangular cover body made up of a front and back cover made of a synthetic resin sheet and a back cover, and an inner surface of at least one cover of the cover body The back side is opened and the other outer edge part is provided with a support piece made of a synthetic resin sheet fixed to the outer edge of the cover body, and two sheets can be stored on the inner surface of the back cover so that thick articles can be stored A cover having a pocket portion formed of a piece, and a hook that can be bent in the thickness direction is provided on each side of the peripheral side other than the opening side of the storage piece, and is in contact with each other. The edge of each flange piece is polymerized and welded to each other to form a bag-like pocket portion as the weld edge, and the storage portion piece of the pocket portion is attached to the inner surface of the other back cover of the cover body. Attached along the welding edge of the cover body Socket portion is formed.
Therefore, the pocket portion with the flange piece can be provided in the cover body with high formability, high strength and low cost without fail by plane processing. In addition, only the cover body and the storage piece of the synthetic resin sheet are welded, and the welding of the collar piece can be done in a flat surface by hot pressing or other crimping work, so that the welding strength is high and the workability is extremely simple. The cover can be manufactured reliably and satisfactorily with a synthetic resin sheet.
[0007]
In addition, in the inventions of claims 2 to 4, since the pocket portion with the flange is formed of a flat synthetic resin sheet, it is not necessary to be folded and the operation of the hot stamping die is simplified and the heat processing is performed. Safety in operation can be remarkably enhanced, and uniform bonding strength can be easily achieved.
[0008]
Furthermore, according to the inventions of claims 5 to 7 , the pocket portion with the scissors provided in the notebook cover or the like can be provided in the cover body by flat processing without fail, with good formability, high strength and low cost. The processing conditions at the time of welding can be easily set and the safety in processing can be improved.
[0009]
In the inventions of claims 8 to 9 , the reinforcement of the pocket portion and the protection of the stored articles are ensured, the welding strength of the synthetic resin sheet is increased, and the processing conditions at the time of bonding can be easily set and the workability is improved. Can be remarkably improved.
