Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention uses polyethylene material to make the passbook bag commonly used in financial institutions such as banks and credit unions strong and easy to manufacture. This article relates to a passbook bag that can be constructed by law and its manufacturing method.

(Prior art) In other words, conventionally, this type of passbook bag has generally been constructed using vinyl chloride material and thermally welded. many,
The construction process is complicated, the materials used are often wasted, and there are drawbacks in terms of labor and time. There was also a method of constructing the main body using polyethylene material, but in this method, the edge of the passbook insertion slot was reinforced with a thicker material, which required complicated and expensive equipment. There was a problem with that.

(Problems to be Solved by the Invention) The present invention was invented to solve these and other problems, and uses a polyethylene material as the main material to reduce the number of places to be heat welded by a simple method. The present invention also provides a passbook bag having a structure in which the rim of the passbook insertion opening can be reinforced, and a method for manufacturing the same.

(Means for Solving the Problems) As a means for solving the problems, the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a surface oblique view of a passbook bag A according to the present invention. Figure 2 is a sloped view of the back side of the same, in which the front side part 1 and the back side part 2 are formed in a continuous state using polyethylene material B, and this is folded in half G, and the upper end of the back side part 2 is further folded. The thick mouth edge 6 is formed by bending and heat welding. Further, the main body 5 is constructed by thermally welding and cutting both side edges 4 of the front surface part 1 and the back surface part 2. In the figure, reference numeral 6 indicates a die-cut portion formed at the upper end of the surface portion 1, and reference numeral 7 indicates a display portion.

Figure 6 a' 1) ' ON Figure 4 a'b'c'd is a drawing showing the manufacturing process of a passbook bag constructed using conventional vinyl chloride material. 9 is a back sheet, 9 is a belt-shaped sheet, 10 is a front sheet made of the same vinyl chloride material, and 11 is a die-cut portion. Figure 5a
・bCd-e'f is a drawing showing the manufacturing process of passbook bag A according to the present invention, in which polyethylene material B is used to construct the continuous front surface portion 1, back surface portion 2, and thick □ mouth edge portion 6. In order to make the bending process more effective, a temporary press line is added using a heat processing bar or the like. 6 and 7 respectively show other embodiments of the polyethylene material B according to the present invention.

(Operations and Examples) That is, when constructing the passbook bag A according to the present invention, the polyethylene material B is formed with a temporary press line L7 by a thermal processing machine such as a thermal processing machine (not shown), as shown in FIG. In this case, the front surface part 1 is closer to the back surface part 2! It goes without saying that the size of the back part 2 can be made smaller, and that the back part 2 can be made larger by that much because the thick mouth edge part 6 continuously formed at the upper end is bent and heat welded.

Next, the folded and overlapped side edges 4 of the front surface part 1 and the back surface part 2 are widely welded and cut with a knife, but as shown in FIG. A method of configuring the main body by simply sealing both sides by processing,
As shown in Fig. 7, when performing horizontal two-sided machining at the same time, there is also a method of welding and cutting at the same time using a hot die blade, but these are of course examples within the technical concept of the present invention. . In this way, at the same time as welding, the die-cut part 11" is cut out using a die-cutting machine.
By dropping the , the passbook bag A according to the present invention is completed.

(Effect of the invention) In other words, the passbook bags used in the past for banks, credit unions, etc. are reinforced by welding a band-shaped sheet prepared elsewhere into the passbook insertion slot by heat welding, so the band-shaped sheet is However, there was a disadvantage in terms of saving labor and materials, as there was a need to prepare a

In the present invention, polyethylene material is used in a folded state,
Further, since the passbook insertion slot is constructed simply by folding and heat welding, it is extremely effective in terms of saving materials, labor, and time.

In addition, in the conventional method of constructing the passbook bag main body using polyethylene material, the passbook insertion opening part was molded into a thick material, making the manufacturing process complicated and expensive. Since it can be easily constructed using conventional heat welding machines, die cutting machines, etc., it is a unique invention that can provide a passbook bag with unprecedented features in terms of price.
