Description

[Detailed explanation of the invention] (Industrial application field) This invention can be used to extract mainly synthetic resin films, such as films for overhead projectors that project various contents on screens for company meetings, school education, etc. A jacket for housing and storing film, more specifically, a jacket for housing and storing film, which is constructed into a bag-like body by gluing and fixing a pair of rectangular ring-shaped members surrounding the peripheral edge of the film. Regarding improvements.

(Prior Art) In conventional jackets of this kind, a pair of rectangular annular members constituting the bag-like body were constructed from a base material of a single material with excellent rigidity, such as plastic film or thick paper.

(Problems to be solved by the invention) In the case of the conventional jacket as described above, when the film is removed from the jacket before use or when inserted into the jacket after use, there is a problem due to the sliding contact between the two. The film and jacket become charged due to the generation of static electricity, and the film and jacket stick together.
When two or more films are housed in one jacket, charging may cause the films to stick together. As a result, it takes time and effort to put in and take out the film, making it extremely troublesome and difficult to use when using the projector, where the film has to be replaced one after another in a meeting or the like.

(Means for Solving the Problems) In view of the above circumstances, an object of the present invention is to provide a film storage jacket that can avoid the above-mentioned conventional drawbacks by improving the material constituting the base material.

The film housing/storage jacket according to the present invention devised to achieve the above object is the one described in detail at the beginning, in which the pair of rectangular annular members constituting the bag-like body are made of a material having excellent rigidity. It is characterized in that it is made of a material with metal foil adhered to at least the inner surface of the bag-like body.

(Function) In the case of the film housing/storage jacket according to the present invention having such a characteristic structure, when inserting the film into the bag-like body constituted by the pair of rectangular annular members, or removing the film from the bag-like body, Since the entire surface where the two come into sliding contact during extraction is made of metal foil, the static electricity generated due to the sliding contact between the two can be dissipated through the metal foil, preventing the film from sticking to the jacket.
In addition, when a plurality of films are stored and used at once, it is possible to prevent the films from being pinched together, making it possible to easily and quickly remove and insert the films.

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a synthetic resin film for overhead projectors, which is generally rectangular in shape. Reference numerals 4 and 4' denote a pair of front and back members formed in a rectangular ring shape so as to surround the four peripheral edges of the film 1;
4' are respectively on both sides of a thick paper base material 2, which is an example of a material with excellent rigidity, as shown in FIG.
The pair of rectangular annular members 4, 4' are made of aluminum foils 3, 3, which are an example of metal foil, adhered via an emulsion type vinyl acetate adhesive 6, 6, and the lower ends of the pair of rectangular annular members 4, 4' are A conductive adhesive 5 mixed with conductive powder such as carbon powder is formed integrally with the bent portion 4A in the shape shown in FIG. The film 1 is adhesively fixed through the opening of the upper edge, and the film 1 is formed into a bag-like body in which the film 1 can be freely inserted and removed. 7 in the figure is an index.

In addition, as the metal foil 3, other than aluminum foil, aluminum alloy foil, stainless steel foil, copper foil, etc. may be used, and as the base material 2, a plastic film other than paper material may be used.

Although not shown, the metal foil 3 may also be attached to the outer surface of the base material 2. At this time, it is more preferable to connect the inner metal foil and the outer metal foil with a strip of metal foil using a conductive adhesive.

Furthermore, although the pair of rectangular annular members 4 and 4' are integrated into a series through the bent portion 4A at their lower ends, they are each manufactured separately and fixed with adhesive at the lower end edge and left and right side edges to form a bag-like body. It's okay to do that.

(Structure of the device) As is already clear from the detailed description above, when using the film storage jacket according to the present invention, (a) the surface that comes into contact when the film is taken out is the metal foil 3;
Since the base material 2 is coated with, it not only has a design effect, but also (b) protects the base material 2 from moisture and moisture, and improves the durability of the jacket itself.

(c) Moreover, the static electricity that is inevitably generated due to sliding contact when removing and inserting the film can be efficiently dissipated due to the good conductivity properties of the metal foil 3, so that the charged film and the jacket can be efficiently dissipated. There are practical effects such as being able to remove the film and insert and store it easily and quickly without any pecking or even pecking of the film itself.
