Description

[Detailed Description of the Invention] The present invention relates to a storage body for storing photographs, documents, etc.

Traditionally, albums were used to organize photos, and scrapbooks and files were used to organize newspapers, documents, etc. However, conventional album books are organized by pasting them on using glue or corners, or by holding them on a mount with plastic film, but the former method is inconvenient due to the use of glue and corners, so it has recently become less popular. is not used very often, and the latter has come to be used exclusively due to the convenience of simply rolling up and holding the plastic film.

However, even with this type of mount that is held between plastic films, the holding force is not strong enough, so there is a risk that the photo may slip through.To prevent this, for example, the As seen in Japanese Patent Publication No. 146575/1983, an album was proposed in which a plastic film was electrostatically charged so that it could be attracted to a mount, and photographs, etc., were held between the film and the mount.
However, in general, static electricity decreases over time and the adhesive force disappears, so it is not possible to hold photos etc. between the mounts with stable force over a long period of time, and the photos etc. may fall out of the album. There was a problem with putting it away.

In order to solve these drawbacks and problems found in conventional albums and scrapbooks, the inventor of the present invention first developed a storage body using vinyl chloride film that has a long-lasting electrostatic adhesive force as shown in Figures 1 and 2. Proposed.

This vinyl chloride film with persistent electrostatic adhesion was previously proposed by the present inventor in Japanese Patent Application No. 138537/1983 (Japanese Patent Publication No. 30940/1983), and has a remarkable ability to trap electric charge. It is a film that promotes the infiltration and diffusion of charges, and has a small ability to seep out and diffuse charges.A unidirectional charge transfer layer is formed on the friction surface of the film, allowing static electricity to persist for a long time.
It has the ability to uniformly disperse charges within the volume and improve charge dispersibility within the resin.

In general, in order for a film or sheet to be able to retain a large amount of charge, it is desirable that the charge not be present only on the surface of the film or sheet but be diffused into its interior. In order to prevent static electricity from decreasing over time, it is desirable that the film or sheet material traps the charges. In other words, if the quantity of electricity easily permeates and diffuses into the volume and is trapped at the diffusion position, the quantity of electricity per unit weight is becomes larger, and because it penetrates and diffuses into the volume, the distribution state when viewed from the surface becomes closer to a uniform state than in the conventional case where only the surface is charged. Furthermore, since the charges trapped within the volume are in a kind of electret state, there is no fear that they will decrease over time.

Therefore, a promoting material that promotes the infiltration and diffusion of charges into the interior and a charge trapping material that prevents charges from being reduced due to the charges that have penetrated and diffused into the interior leaking out again are mixed into the vinyl chloride resin. if,
It is possible to produce films and sheets that have a much better sustained electrostatic adhesion than conventional ones. However, a material that promotes the infiltration and diffusion of charges into the interior naturally also promotes the infiltration and diffusion of charges from the inside to the outside, and therefore does not provide long-term electrostatic adhesion. From this point of view, the charge trapping material must be unidirectional, that is, a material that promotes infiltration and diffusion similar to a rectifying action, but has a small percolation and diffusion ability, and has an excellent charge trapping ability. Expressed in equivalent terms in terms of an electric circuit, the charges trapped inside form a capacitor between the surface to be adhered to, such as a mount, and the facing surface of the film, and the insulation resistance of the capacitor is rectified. It must have effective resistance properties.

And, the patent application filed in 1983, which was previously proposed by the inventor of the present application,
The vinyl chloride film containing medium molecular weight organic ketone disclosed in No. 138537 exhibits extremely remarkable charge trapping performance, charge penetration/diffusion performance, and rectifying resistance properties, and is stable for a long period of time. It shows a long-lasting electrostatic adhesion force. The storage body shown in FIGS. 1 and 2 using a vinyl chloride film having such a persistent electrostatic adhesive force can freely attach and detach the vinyl chloride film 3 having a sustainable electrostatic adhesive force on at least one side (preferably both sides) of the mount 2. The stored items 4 are attached to the vinyl chloride film 3 between the mount 2 and the vinyl chloride film 3.
At the same time as attaching it to the mount 2, the mount 2
A plurality of storage bodies 1 are formed into a book shape, and a storage object 1 is held between the storage bodies 1 and 4.

According to such a storage body, vinyl chloride film 3
has an electrostatic adhesion force, so it statically attracts to the mount 2 and holds the stored items 4 firmly. Roll up the vinyl chloride film 3, place the stored items 4 such as photos and documents on top, and then wrap the vinyl chloride film 3. It can be easily stored by simply putting film 3 back in place.
On the other hand, you can also easily take out stored items. In addition, it is extremely preferable because it can be used repeatedly and repeatedly.

However, since the stored items 4 are held down and supported only by the electrostatic adhesive force of the vinyl chloride film 3,
The user may be worried that the stored item 4 will fall out, and if the stored item 4 is heavier than the electrostatic adhesion of the vinyl chloride film 3, it will fall out, so thick items cannot be stored. It has the disadvantages of limiting the things that can be stored and reducing the variety of things that can be stored.

In view of these drawbacks, the present invention aims to provide a container for storing photographs, documents, etc. that solves the problem.The features of the present invention are to improve the ability of the film to capture and infiltrate and diffuse charges, and to improve the ability to absorb and diffuse charges into the film. A covering sheet 13 made of vinyl chloride film, which has been blended with a medium-molecular-weight organic ketone to reduce the electrostatic adhesion force, is adsorbed onto almost the entire surface of at least one side of the mount 12 so as to be able to freely come into contact with and separate from the mount 12. A pressure-sensitive adhesive layer is formed by applying a pressure-sensitive adhesive 15 near the periphery of the cover sheet 12, and the periphery of the covering sheet 13 is releasably adhered and held to the mount 12 by the pressure-sensitive adhesive. It is in.

The present invention will now be described in detail with reference to the embodiments shown in FIGS. 3 to 5.

Fig. 3 is a perspective view of the storage book shown in an open state, and Fig. 4 is a perspective view showing one storage body, and the storage book is composed of a plurality of storage bodies shown in Fig. .

In the figure, reference numeral 11 denotes a storage body, which is made up of a mount 12 and a covering sheet 13 made of vinyl chloride film having persistent electrostatic adhesion. Reference numeral 15 denotes a pressure-sensitive adhesive provided in a band shape on the base end side surface of the mount 12. It is preferable that the mount 12 has a particularly smooth surface because the surface in contact with the vinyl chloride film 13 having electrostatic adhesion will come into close contact with the mount 12 and increase the adsorption force.

The covering sheet 13 is preferably fixed to the leading end side of the mount 12 and provided on both sides of the mount 12.
It may be provided by folding back from the tip of 2 over both sides. Further, although the covering sheet 13 is normally provided on both sides of the mount 12, it can also serve the purpose even if only one side is provided.

The position and shape of the pressure sensitive adhesive 15 are as follows:
The present invention is not limited to the above-mentioned embodiments, and an appropriate position on the surface near the peripheral edge of the mount 12 can be selected, and the shape in which it is provided can also be changed as appropriate. For example, the position may be on the proximal side of the mount 12 as shown in FIGS. 5A to C, or along the upper and lower sides from the proximal side of the mount 12 as shown in FIG. 5D, or as shown in FIG. 5E. The upper side 15e and lower side (15e
Although not shown, it may be provided only on the upper side or only the lower side of the mount 12, and the shape may be linear 15a as shown in FIG. 5A, or as shown in FIG. 5B. They may be dotted lines 15b, or they may be provided at appropriate intervals 15c as shown in Figure 5C, or
It can be provided in a U-shape 15d as shown in Figure D, or as shown in Figure 5E.
It seems that they can be used in combination as shown in the following.

Therefore, in the present invention, as shown in FIG. 4, a stored item 14, such as a photograph, is placed between a mount 12 and a covering sheet 13 having electrostatic adhesive force. ,
Cover sheet 13 is placed on mount 1 for storing photographs, etc.
When peeling from 2 and after storage, cover sheet 1
This occurs due to friction when superimposing and pressing 3 onto the mount 12. Therefore, after positioning the stored item 14 on the mount 12, the peeled covering sheet 1
3 is returned to its original position and pressed, the covering sheet 13 statically adheres to the surface of the mount 12 and the stored items 14 and presses the stored items.
Because it is stuck and held on the mount 12 by
The stored items 14 are firmly held without falling out.

Thus, according to the storage unit for photos, documents, etc. of this invention, the opening and closing side edges of the covering sheet made of vinyl chloride film that has been given a persistent electrostatic adhesive force are removably attached to the mount using a pressure-sensitive adhesive. As a result, the opening/closing side edges of the covering sheet that covers the stored items and attracts static electricity to the mount are securely held on the mount, eliminating the risk of the user worrying about the stored items falling out. be.

In addition, it can be easily stored by simply rolling up the covering sheet, placing stored items such as photos and documents on the mount, and then returning the covering sheet to its original position.It is not only extremely convenient to use, but also allows for easy storage of stored items. When you want to take it out, you can easily take it out by simply rolling up the cover sheet, and it can also be used again, so it has the advantage of being able to be used repeatedly and as many times as you like. Furthermore, the following effects are also achieved.

(b) Photos can be moved freely and easily taken out and viewed.

(b) Even after many years of use, when the photo is removed, it will not be damaged or deteriorate due to the adhesive.

(c) When the cover sheet is opened and closed, since the pressure-sensitive adhesive is not applied to the entire surface of the paper as in the past, wrinkles do not occur due to contact between the cover sheet and the adhesive surface.

(d) You can write articles and records on the mount as well as file photos.

(E) It is possible to print on the backing paper, draw illustrations, etc., and save it with photos.

(f) Thin travel memo paper, various pamphlets, commemorative stickers, etc. can be stored together with photos and taken out at will. Commemorative stamps can also be printed on the mount.

(g) The mount can be made thinner and lighter, making it convenient to carry. It is lightweight because there is no pressure-sensitive adhesive applied to the entire surface of the mount as in the past.

(h) The production process is simple and requires less paper material, so the price can be lower.
