Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing method for providing a window to a lid or a body of a container including a case such as a pen case or a bag such as a small case, or a cover such as a file.

[0002]

2. Description of the Related Art Conventionally, for example, when a window is provided in a lid of a case such as a pencil case, generally, all of the lining materials, core materials, cushion materials and exterior materials that compose the lid are stacked. The material is preliminarily provided with a window hole, a transparent material is disposed so as to close the window hole, and all the materials described above and the transparent material are integrally joined by means such as welding at the peripheral portion of the window hole. The method is adopted.

[0003]

In the above-mentioned manufacturing method, the preparation work is troublesome because it is necessary to preliminarily form a window hole in all the materials to be laminated. In addition, alignment of the window holes of each material when joining the transparent materials was troublesome. Further, the window obtained by the above manufacturing method has a problem that the contour is not clear and the appearance is not good. Therefore, the present invention has the trouble of preliminarily forming window holes in all materials,
Innovative container lids or bodies or covers that eliminate the hassle of matching the positions of the window holes of each material to facilitate the process, and also make the contours of the windows sharper to improve the appearance. It is intended to provide a method for manufacturing a window.

[0004]

In order to achieve the above object, a method of manufacturing a window in a lid or a body of a container or a cover of the present invention comprises a transparent material 5 made of a thermoplastic resin and an elastic foam material 7.

The peripheral edge portion of the window hole of the outer jacket material 10 and the peripheral end portions of the covering material 8, the elastic foam material 7, the transparent material 5 and the inner layer material 6 are integrally welded by 2 and a certain width from the welded portion 15 At the inner portion, the covering material 8 and the elastic foam material 7 are integrally welded to the transparent material 5 by the inner welding blade portion 13, and at the inner end of the welding portion 16, the covering material 8 and the elastic foaming are made by the fusion cutting blade portion 14. The material 7 is blown.

Next, by removing a part 8a (see FIG. 2) of the covering material 8 and a part 7a (see FIG. 2) of the elastic foam material 7 which are blown off on the transparent material 5 as described above. As shown in FIGS. 1 and 2, the window 2 whose contour is clearly framed by the covering 8 is completed. A pocket 17 is formed between the transparent material 5 of the window 2 and the inner layer material 6, and a photo or various cards are inserted into the pocket 17 through the slits 18 provided in the inner layer material 6. Can be held. still,
Instead of providing the slits 18 in the inner layer material 6, as shown in FIG. 6, the vertical width or the horizontal width of the inner layer material 6 is made slightly smaller than that of the transparent material 5 so that the inner layer material 6 has only three sides with respect to the transparent material 5. It is also possible to fuse and open the remaining one side, and use the opened one side as an insertion port 19 for photographs, various cards, and the like.

Next, FIG. 7 shows a second embodiment. This embodiment also shows the same method of making a brush as in the first embodiment. First, as shown in (a),
On the lower mold 4 of the welder, a sheet-shaped transparent material 5 made of soft vinyl cut into a rectangle slightly smaller than the lower mold 4 and a semi-transparent inner layer material 6 also made of soft vinyl.
Place and on top of each other. Incidentally, the inner layer material 6 is provided with slits or one side is opened as in the first embodiment. Next, a sheet-like outer covering material 10 made of soft vinyl having an arbitrary pattern printed or processed on the outer surface and the inner surface is placed thereon. Further thereon, an elastic foam material 7 such as a sponge and a sheet-shaped colored covering material 8 made of soft vinyl are placed. Then, the upper mold 11 of the welder is pressed from above on each of the stacked materials. The upper mold 11 is provided with outer and inner double welding blade portions 12 and 13, and a welding blade portion 14 is continuously provided at the inner end of the inner welding blade portion 13. This upper die 11 is, as shown in FIG.
2, the peripheral portion of the covering material 8, the elastic foam material 7, and the covering material 1
0, the transparent material 5 and the inner layer material 6 are integrally welded, and the coating material 8, the elastic foam material 7 and the outer coating material 1 are formed by the inner welding blade portion 13 at an inner portion of the welding portion 15 by a certain width.
0 is integrally welded to the transparent material 5, and the covering material 8, the elastic foam material 7 and the outer jacket material 10 are melt-fused at the inner end of the welded portion 16 by the fusing blade portion 14. And the transparent material 5
By removing the part 8a of the covering material 8 that has melted off above, the part 7a of the elastic foam material 7, and the part 10a of the outer covering material 10,
As shown in (c), the window 2 whose contour is clearly framed by the covering material 8 is completed. A pocket 17 is formed between the transparent material 5 of the window 2 and the inner layer material 6.

In each of the above embodiments, the inner layer material 6 is superposed below the transparent material 5 to provide the pocket 17, but the inner layer material 6 is not necessary when the pocket 17 is not provided.

Further, in each of the above-mentioned embodiments, the window 2 is provided on the body of the pen case 1. However, the present invention can be implemented when the window is provided on the lid or body of another container. Others,
It can also be implemented when a window is provided on the cover of a file or the like.

[0013]

The present invention is as described above. According to the first aspect of the present invention, since it is sufficient to form the window hole 9 only in the outer covering material 10, the window hole can be formed in another material. Manufacturing can be facilitated by omitting the trouble of providing and the trouble of aligning the window holes of each material. According to the second aspect of the present invention, since it is not necessary to make a window hole in the outer covering material 10, the manufacturing can be further facilitated. Further, since the completed window 2 is contoured by the covering material 8, and the edge is swelled by the elastic foaming material 7 included therein and becomes three-dimensional, the window 2 becomes clear and clear and has a good appearance. Get better Further, by forming the pocket 17 by stacking the inner layer material 6 under the transparent material 5, it is possible to obtain the convenience of being able to insert and hold a photograph or various cards inside the window 2.
