JPH0612949Y2 - 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, memorials, etc. have a variety of interesting designs on the cover plate so that buyers can easily confirm the design and that the cover plate is not contaminated. The 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 known protective case 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 that are integrally continuous through a fold line, respectively, and On the surface of the cardboard having a hole formed in the front piece, a development plate formed by laminating a transparent resin film is bent along each folding line, and the one side piece and the fixing piece are polymerized, The polymerized portion was adhered with an adhesive.

The problem to be solved by the invention is, however, that the above-mentioned conventional configuration includes a step of adhering one side surface of a development plate having a transparent resin film laminated on the surface thereof with an adhesive, particularly due to excess or insufficient adhesive. There is a risk that the adhesive may stick out to the peripheral edge or the entire surface of the overlapping part may not be properly adhered, which may damage the appearance of the product, workability may be poor, and when inserting an album etc. in the protective case, The edge of the cover plate of an album, etc. may be caught by the edge of the window hole formed in the front piece, which may hinder the insertion of the album or damage the edge, which is inconvenient to handle. Met.

Therefore, in order to solve the problems of the conventional ones described above, the present application forms one side piece, a front side piece, the other side piece, a rear side piece, and a fixing piece with a polygonal line, respectively. Through one continuous, and
On both front and back sides of a cardboard with a window hole formed in the front piece, a development plate laminated on a transparent resin film is bent along each folding line, and the one side piece and the fixing piece are polymerized. Then, the overlapping portion is heat-welded, and one or both of the films is cut at the position of the window hole to form an opening.

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.

In addition, the instruction sheet and price sheet from the manufacturer of the album etc. to the retailer about the sale of the album etc., and the message sent to the other party in the case of gift giving etc., the front and back that cover the window hole through the opening Intervenes between the two resin films.

Example Hereinafter, with reference to the drawings, an example of the present application will be described in detail. The developing plate (1) has one side piece (2) having a narrow width substantially equal to the back width of an album and the like, and a cover plate for the album and the like. A substantially square front piece (3) of approximately the same size as the one side piece (2)
The other side piece (4) having a width equal to that of the front side piece (3), the rear side piece (5) of the same size as the front side piece (3), and the fixation piece (6) polymerized and fixed to the one side piece (2). ) And are respectively connected continuously via a broken line (7), and
A transparent resin sheet (9) is provided on the front and back sides of a piece of cardboard having a relatively large rectangular window hole (8) formed on the front piece (3).
(10) are laminated respectively, and the expansion plate (1) thus constructed is mountain-folded from each folding line (7), and the fixing piece (6) is superposed on the inner surface of one side piece (2). Then, the polymerized portion is heat-welded by high-frequency welding, ultrasonic welding or hot plate pressure welding, and further, a resin film (9) covering the window hole (8) along one side of the window hole (8). ), (10) and / or (10) are cut to form an opening (11), thereby forming a flat rectangular cylindrical protective case having upper and lower end surfaces opened as shown in FIG. It

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).

Further, generally, the manufacturer of the album or the like delivers the instruction sheet, the price sheet, or the advertising paper for advertising regarding the sale of the album or the like to the store. In this case, the above-mentioned instruction sheet or the like is provided in the opening (11). Therefore, when interposing between the transparent resin films (9) and (10) covering the window hole (8), and when using an album etc. for gifts etc., the card with a message etc. is filled with the above opening ( According to 11), it is interposed between the transparent resin films (9) and (10) covering the window hole (8).

Effect of the Invention In the present application, since the inner surface of the window hole is also covered with the synthetic resin film as described above, when the album or the like is inserted into the protective case, the edge thereof is pulled to the edge of the window hole. According to the present application, the synthetic resin film is laminated on the front and back sides of the cardboard, so that one side piece and the fixing piece are interposed by the synthetic resin film. Since it is polymerized by heat, heat welding is possible, and by the heat welding, one side piece and the fixing piece can be fixed cleanly and surely, and the workability is excellent. The space between the resin films covering the window hole from both sides can be used for storing the instruction sheet delivered from the manufacturer to the store or the message of the gift giver, and is convenient to use. Has advantages such as It
