Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a release material for card files.

[0002]

[Prior art]

 One example of a conventional card file is shown in FIGS. 5 and 6, reference numeral 1 denotes a rectangular file body made of paper, a synthetic resin film, or the like, and forms a front cover 2, a spine 3 and a back cover 4.

The file body 1 has a fold 5 at the boundary between the front cover 2 and the spine 3, and a fold 6 at the boundary between the spine 3 and the back cover 4. They are parallel to each other at intervals and extend substantially perpendicular to the longitudinal direction of the file body 1.

[0004] The portion surrounded by the folds 5 and 6 on the inner surface of the file body 1, that is, the inner surface of the spine 2, retains a strong adhesive force over almost the entire width except for both ends thereof for a long period of time. A mucous membrane 7 made of an adhesive material is formed.

[0005] A strip-shaped release paper 10 large enough to cover the mucous membrane 7 is attached to the upper surface of the mucous membrane 7, and the release paper 10 is spaced apart by about 1 mm along its longitudinal direction. A plurality of perforations 11 are engraved.

However, when filing cards such as business cards, photographs, postcards, drawings, telephone cards, and traffic cards, after arranging a large number of cards 12, the width of the spine 3, namely, the folds The sheets are aligned and stacked by an amount substantially equal to the interval between 5 and 6.

Then, after exposing the mucous membrane 7 by peeling off the release paper 10, one edge of the card 12 piled up earlier is collectively pressed against the mucous membrane 7, and the one edge becomes the mucous membrane 7. Is firmly bonded to the inner surface of the spine 3. Then, when the front cover 2 and the back cover 4 are folded inward along the folds 5 and 6, the card 12 is covered with the front cover 2 and the back cover 4.

When the number of the cards 12 is small, as shown in FIG. 6, the mucous membrane 7 is partially exposed by tearing off the release paper 10 along a desired perforation 11, and the card 12 is exposed on the exposed portion. Press one edge.

[0009]

[Problems to be solved by the invention]

 In the above-mentioned conventional card file, the release paper 10 is adhered to the upper surface of the mucous membrane 7 in order to prevent the mucous membrane 7 from being stained and to maintain its adhesive force for a long period of time. In the case of filing one sheet or two sheets at a time, a release paper having a width of about 1 mm must be peeled off along the perforations 11 in order to expose the mucous membrane 7 by a width corresponding to the thickness.

However, the release paper 10 is formed by performing a release treatment on the back surface of the paper and then engraving a perforation 11 on the back surface of the paper. Since the adhesive penetrates into the inside, the release paper having a width of about 1 mm breaks along the perforation 11 and breaks in the middle of the release paper, and is pulled from the upper surface of the mucous membrane 7 over its entire length. It was difficult to peel off.

[Means for Solving the Problems]

 The purpose of the present invention is to solve the above-mentioned problem. The gist of the present invention is to extend the strong adhesive force formed on the inner surface of the spine of the file body constituting the cover, spine and back cover. In a release material for a card file covering a mucous membrane made of an adhesive held over a period of time, the outer surface of a small-diameter string-like rod made of a synthetic resin having high flexibility is subjected to a peeling treatment, and these many rods are attached to the mucosa. A card file release material characterized by being arranged adjacent to each other along the longitudinal direction of the spine.

Another feature is that the adjacent rods are connected to each other via a thin film which is easily broken.

Another feature is that the rods are extruded so as to be adjacent to each other and arranged side by side, subjected to a peeling treatment on the outer surface thereof, and then arranged on the mucous membrane.

Another feature is that the above-mentioned adhesive film is formed on the upper surface of the backing sheet attached to the inner surface of the above-mentioned spine.

Still another feature is that a mucous membrane made of the adhesive is formed on the lower surface of the mount, the release paper covering the mucous membrane is peeled off, and the mount is adhered to the inner surface of the spine. It is in.

Still another feature is that the above-mentioned mucous membrane is formed on the upper surface of a long mount at a predetermined interval in the longitudinal direction, and a large number of rods are arranged on the mucous membrane to form the mount and release. The material is cut at the center of the interval to have a predetermined length.

[0017]

[Embodiment of the invention]

 FIG. 1 shows an embodiment of the present invention, in which (A) is a partial perspective view, and (B) is an enlarged sectional view taken along line BB of (A).

The inner surface of the spine 3 of the file main body 1 constituting the front cover 2, the spine 3 and the back cover 4 is made of paper through a mucous membrane 21 made of an adhesive which retains a strong adhesive force over a long period of time. A mount 22 made of a resin film or the like is attached, and a mucous membrane 23 is formed on the upper surface of the mount 22 by applying an adhesive that retains a strong adhesive force over a long period of time.

On the mucous membrane 23, a number of string-like rods 24 are arranged adjacent to and parallel to each other along the longitudinal direction of the spine 3. Many of these rods 24 are formed by extruding a flexible synthetic resin such as polyethylene or polypropylene, and have a small diameter (for example, 0.5 mm to 1 mm) circular cross-section. After applying an amino acid-based resin, a so-called peeling treatment for heating the resin is performed.

However, when the card 12 is filed in a small amount (for example, two), as shown in FIG. 1A, one rod 24 corresponding to the thickness is held by the end. The card 12 is peeled off from the mucous membrane 23, and is bonded to the exposed mucous membrane 23 by pressing one edge of the card 12 as shown in FIG. 1 (B). By repeating the above, the card 12 can be filed by an amount equal to the width of the spine 3.

Thus, the rod 24 is made of a synthetic resin having a high flexibility, and its outer surface is subjected to a peeling treatment and is arranged on the mucous membrane 7 adjacent to each other. Even this can be easily peeled off the mucous membrane 23 without breaking it.

A large number of rods 24 can be individually extruded and subjected to peeling treatment on their outer surfaces, and then placed on the mucous membrane 23 in a state where they are adjacent to each other and arranged side by side. A large number of rods 24 can be extruded at once from a large number of holes in a state of being adjacent to each other and juxtaposed to each other.

Further, a double-sided tape in which both sides of the adhesive are covered with release paper is peeled off one of the release papers and adhered to the lower surface of the backing paper 22, and the other release paper is peeled off and the backing paper 22 is put on a double-sided tape. It can also be pasted on the inner surface of the spine 3 via a hook.

As shown in FIG. 2, a mucous membrane 23 is formed by applying an adhesive on the upper surface of a long mount with a predetermined interval W therebetween, and a number of rods 24 are arranged on the mucous membrane 23. After that, the mount 30 and the rod 24 can be cut at the center of the interval W to have a predetermined length L, that is, the length of the spine 3.

In the above embodiment, the backing sheet 22 is attached to the inner surface of the spine 3, but the mucous membrane 23 may be formed by directly applying an adhesive to the inner surface of the spine 3 as shown in FIG. it can.

As shown in FIG. 4, the cross section of a large number of rods 24 can be polygonal, and adjacent rods 24 can be connected via a thin film 25 that is easily broken.

[0027]

[Effect of the invention]

 In the present invention, the outer surface of a small-diameter string-like rod made of a synthetic resin having high flexibility was subjected to a peeling treatment, and a number of these rods were arranged adjacent to each other on the mucous membrane along the longitudinal direction of the spine. However, even a single rod can be easily peeled off the mucous membrane without breaking it.

If adjacent rods are connected to each other via a thin film which is easily broken, the thin film can be easily cut when the rod is peeled off, and the adhesive overflows from a gap between the adjacent rods. Can be reliably prevented by the thin film.

By extruding a large number of rods in a state of being adjacent to and juxtaposed to each other and subjecting them to peeling treatment on the outer surface thereof and then arranging them on the mucous membrane, the numerous rods can be easily and quickly arranged on the mucous membrane. can do.

If a mucous membrane is formed on the upper surface of the backing sheet to be attached to the inner surface of the spine, and a number of rods are arranged on the mucous membrane, this mounting sheet can be attached to the inner surface of the spine of any file body. Can be.

When a mucous membrane made of an adhesive is formed on the lower surface of the backing sheet, the release paper covering the mucous membrane is peeled off, and the backing sheet is adhered to the inner surface of the spine. It will be easier.

A mucous membrane is formed on the upper surface of a long mount at a predetermined interval in the longitudinal direction, a number of rods are arranged on the mucous membrane, and the mount and the release material are cut at the center of the interval. If the length is set to a predetermined length, the production of the backing sheet becomes easy.
