JPH0612948Y2 - Protective case for albums - Google Patents

Description

TECHNICAL FIELD The present application relates to a protective case for protecting an album or the like.

2. Description of the Related Art In general, albums or memorials, etc. are provided with various hobby designs on the cover plate, so that the purchaser can easily confirm the design and the cover plate is not damaged. An album or the like is stored in a flat, rectangular tube-shaped protective case having upper and lower end surfaces opened, and the album or the like is transported in this state and displayed at a store or the like.

A protective case known to be used for such a purpose has one side piece, a front side piece, the other side piece, a rear side piece, and a fixing piece, which are integrally continuous through a fold line, respectively, and , A development plate formed by laminating a transparent resin film on the entire surface of the cardboard having a window hole formed in the front surface is bent along each folding line, and the one side piece and the fixing piece are polymerized. The polymerized part was adhered with an adhesive.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, according to the above-described conventional configuration, the method includes a step of adhering one side surface of a development plate having a transparent resin film laminated on its surface and a fixing piece with an adhesive, Adhesive may stick out from the periphery due to excess or shortage, or the entire polymerized part may not be properly adhered, which may impair the appearance of the product and the workability may be poor.
Also, when inserting an album or the like into the protective case, the edge of the cover plate of the album or the like may be caught by the edge of the window hole formed in the front piece, which may prevent the insertion of the album or the like or damage the edge. There was a fear of giving.

Means for Solving the Problems Therefore, in order to solve the problems of the above-mentioned conventional ones, the present application includes one side piece, a front side piece, the other side piece, a rear side piece, and a fixing piece, which are broken lines, respectively. And a front side and a back side of a cardboard having a window hole formed in the front piece, and a development plate formed by laminating transparent resin films on the front and back sides, respectively. The side piece and the fixing piece are polymerized, and the polymerized portion is fixed by heat welding.

Function However, as in the conventional case, when an album or the like is inserted into the protective case, the entire inner surface of the protective case is covered with the resin film, so that smooth insertion can be performed, and
The design applied to the cover plate of the album or the like stored in the protective case is seen through the window hole.

Example Hereinafter, with reference to the drawings, an example of the present application will be described in detail. The developed version (1) includes one side piece (2) having a narrow width almost equal to the spine width of an album or the like and a cover of the album or the like. A substantially square front piece (3) of approximately the same size as the plate and the one side piece
(2) The other side piece (4) having a width equal to that of (2), the rear piece (5) of the same size as the front piece (3), and the one side piece (2) that is polymerized and fixed. The piece (6) and the piece (6) are continuously connected to each other via the fold line (7), respectively, and the front piece (3) has a relatively large window hole (8) formed on the front and back surfaces of a piece of cardboard. , Transparent resin sheet (9), (10)
Each of which is laminated, and the expansion plate (1) configured in this manner is mountain-folded from each folding line (7) and one side piece
The fixing piece (6) is superposed on the inner surface of (2), and the superposed portion is heat-welded by high frequency welding, ultrasonic welding or hot plate pressure welding,
As shown in the figure, a flat rectangular tubular protective case having upper and lower end surfaces opened is configured.

In the protective case configured in this way, as in the past,
Along with the storage of albums and the like, the designs such as designs on the cover plate are seen through the window hole (8).

Effect of the Invention As described above, in the present application, since the inner surface of the window is also covered with the transparent resin film, when the album or the like is inserted into the protective case, the edge thereof is pulled to the edge of the window. It is easy to use because it is not likely to be hung or damaged, and according to the present invention, one side piece and a fixing piece are made by laminating transparent resin film on the front and back sides of cardboard. Is polymerized through a resin film, heat fusion is possible, and the one side piece and the fixing piece can be cleanly and surely fixed by the heat welding, and
It has advantages such as excellent workability.

[Brief description of drawings]

The drawings show the embodiments of the present application. FIG. 1 is a general perspective view, FIG. 2 is an enlarged sectional view taken along the line II of FIG. 1, and FIG. 3 is a plan view of a development plate. In the figure, (1) is a development plate, (2) and (4) are side pieces, (3) is an upper piece, (5) is a lower piece, (6) is a fixed piece, (7) is a broken line, and (8) ) Is a window hole, (9), (10)
Is a resin film.

Claims (2)

[Scope of utility model registration request] 1. A side piece on one side, a front side piece, and a side piece on the other side,
