Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a holder for photographic articles such as photographic film and prints, and more particularly to an improved holder for strip-shaped photographic articles such as photographic negatives and microfilm. , allows photographic articles such as photographic film to be easily stored and observed, can be easily inserted during transportation, and can be prevented from inadvertently slipping out of the holder.

BACKGROUND OF THE INVENTION Holders or jackets for photographic articles such as strips and individual photographic negatives, films, prints, slides, etc., such as those disclosed in U.S. Pat. Widely used in commercial and consumer applications. Such holders are generally formed of a pair of transparent plastic film sheet-like members with a space between the sheet-like members to form a retention pocket in the sheet-like member with dimensions suitable for insertion of the photographic article. It has a plurality of vertically and horizontally spaced bonding seal lines.

Such a holder is then stored in a file or book, and is used to hold photographic negatives, films, prints, etc. during scanning, copying, or enlarging during photographing or other processes. Support photographic items.

Various types of holders are used, but holders for multiple sheets of the same size can be attached as pages in a book such as a ring binder, or in a file-type drawer installed in a desk. It is now possible to hang it. This type of holder has a series of parallel holding pockets arranged in multiple stages along either the short side or the long side of the holder.

These holding pockets are of the top-loading type, in which the photographic article is inserted approximately along the width direction of the photographic article through the loading opening provided at the top, and the holding pocket is of the top-loading type, in which the photographic article is inserted through the loading opening provided at the side. There are two types: side-loading, which slides along the length of the device.

<Problems to be Solved by the Invention> Of these two types of holding pockets, the top-loading type has a relatively large loading opening, so it has a side opening that can be inserted and slid through a relatively narrow loading opening. Photographic articles are more likely to fall out of the holding pocket and be damaged than with a reloadable type. For example, if the holder is bound as a page in a file, the photographic item may be inadvertently removed from the holding pocket when the holder is removed, the file is moved, or the file is being used. Easy to get out of.

In order to prevent such a photographic article from falling out of a top-loading holding pocket, it is conceivable to make the length of the loading opening provided at the top of the holding pocket shorter than the length of the photographic article. However, if the size of the loading port is reduced in this way, although it is possible to prevent the cartridge from falling off, it becomes difficult to insert the cartridge into the holding pocket.

In addition, if the width of the holding pocket is made sufficiently larger than the width of the photographic article, it will be possible to insert the photographic article easily even if the loading opening is made smaller as described above. Since it is easy to move and may be tilted, it is inconvenient when observing photographic articles together with the holder.

The present invention has been made by focusing on such conventional technology, and in a top-loading type holder, the loading opening of the holding pocket can be opened while keeping the width of the holding pocket substantially corresponding to the width of the photographic article. To provide a holder for a photographic article in which the photographic article can be easily inserted and taken out even if the holder is smaller than the photographic article, and the photographic article does not fall out of the holding pocket no matter how the holder is handled.

<Means for Solving the Problems> The holder for photographic articles according to the present invention will be explained with reference to FIG. 1 of the embodiment. The holder for photographic articles of the present invention has at least one top-loading type holding pocket 14 in which a length of photographic film (photographic article) 30 having a constant width is stored, and the holder has a pair of overlapping plastic sheets. (Sheet-like member) 11A, 11B, photographic film 30
Bottom seal line 12 of slightly longer size than
and a side seal line 13 having a length approximately corresponding to the width of the photographic film 30, and a first regulating seal portion 18A having a longer dimension on one side of the loading opening 16 at the top and a first regulating seal portion 18A having a shorter dimension on the other side. By providing the second regulating seal portions 18B respectively, the loading port 1
6 is made slightly shorter than that of the photographic article 30, and a slit opening 20A for protruding the corner 32 of the photographic article 30 is provided at least at a position on the first regulating seal portion 18A side of the bottom seal line 12. It is structured as follows.

<Function> According to the holder for photographic articles according to the present invention,
The corner 32 of the photographic film 30 inserted into the loading opening 16 of the holding pocket 14 is aligned with the bottom seal line 1.
Since it falls into the slit opening 20A provided in 2,
One end of the photographic film 30 can be brought into a state where it is sufficiently inserted below the regulating seal portion 18A. Therefore, the length of the loading port 16 is the length of the photo film 3.
Although it is shorter than 0, photographic film 3
0 can be easily loaded into the holding pocket 14. After loading, when the photographic film 30 is slid toward the other regulating seal section 18, both ends of the photographic film 30 are attached to both regulating seal sections 18A,
18B, and the photographic film 30
falling out of the holding pocket 14 is reliably prevented.

Also, the width of the photographic film 30 and the holding pocket 1
Since the widths of the photo film 30 are matched, the photographic film 30 will not be tilted in the holding pocket 14, and it is convenient to observe the photographic film 30 while it is in the holding pocket 14.

<Example> Hereinafter, a preferred example of the present invention will be described based on the drawings.

1 to 4 are diagrams showing a first embodiment of the present invention. This embodiment has a rectangular holding pocket 1 for inserting a photographic film (photographic article) 30.
4 shows a holder 10 having only one holder 4. This holder 10 consists of a pair of plastic sheets (sheet-like members) 11A and 11B.
The plastic sheets 11A and 11B are provided with a bottom seal line 12 having a size slightly longer than the photographic film 30, and a side seal line 13 having a length corresponding to the width of the photographic film 30.
This bottom seal line 12 and side seal line 1
3, the contour of the holding pocket 14 is determined. Since the seal lines 12 and 13 on the bottom and sides have the lengths described above, the outline size of the holding pocket 14 is that the length is slightly longer than the photographic film 30 and the width is commensurate with the photographic film 30. It has become a thing of the past.

At the top of this holding pocket 14 is a loading opening 16 formed by leaving the upper edges of the plastic sheets 11A, 11B in an unsealed state. The length of this loading port 16 is slightly shorter than the length of the photo film 30, and the length of the photo film 30 is
The length is approximately 90% of the length of . A long first regulation seal portion 18A is provided on one side of the loading port 16, and a short regulation seal portion 18B is provided on the other side.

Further, unsealed slit openings 2 are provided at both ends of the bottom seal line 12, that is, on the first regulation seal portion 18A and second seal portion 18B sides.
0A and 20B were provided.

Next, the procedure for loading the photographic film 30 into the holding pocket 14 will be explained.

First, the photographic film 30 is inserted into the loading opening 16 of the holding pocket 14 from one end thereof at a certain angle, and the angle 32 of the photographic film 30 is inserted into one of the slit openings 2 provided in the bottom seal line 12.
0A and hold the corner 32 in the holding pocket 1.
4. Let it protrude outward (see Figure 2). By dropping the corner portion 32 of the photographic film 30 into the slit opening 20A in this way, one end of the photographic film 30 can fully enter below the regulation seal portion 18A.
The other end can also be inserted directly into the holding pocket 14 from the loading port 16 without interfering with the other regulating seal portion 18B. In this way, one end of the photographic film 30 is made longer by the restriction seal portion 18A into which it is inserted, and the other restriction seal portion 18B is short enough to engage with the other end of the photographic film 30.
Therefore, the overall length of the holding pocket 14 can be kept short compared to the case where both of the regulating seal parts 18A are long, and the other end of the photographic film 30 when inserted can be It does not interfere with the regulation seal portion 18B. Note that another slit opening 20 is also provided on this shorter regulation seal portion 18B side.
B is provided, but this is only used to push up the other end of the photo film 30 when removing the photo film 30, and is only used when loading the photo film 30. It is only the slit opening 20A on the regulating seal portion 18A side.

The photographic film 30 loaded into the holding pocket 14 as described above is in a state in which one end thereof is engaged with one of the regulating seal parts 18A, but the other end thereof is engaged with the other regulating seal part 18B. (see FIG. 3), the photographic film 30 is slid toward the other end so that the other end of the photographic film 30 is also engaged with the regulation seal portion 18B. This completes the loading of the photo film 30.
The photographic film 30 is reliably prevented from falling off during movement or handling of the holder. In other words, the displacement of the photographic film 30 in the longitudinal direction is regulated by the frictional force with the plastic sheets 11A, 11B, and each regulating seal portion 18A, 18B engages with one end and the other end of the photographic film 30, so that the photographic film 30 is 30 from falling off from the loading port 16.

Photographic film 30 loaded in this way
The width of this photographic film 30 and the holding pocket 1
Since the widths of the photo film 4 are matched, the photographic film 30 will not be tilted in the holding pocket 14, and it is convenient to observe the photographic film 30 while it is in the holding pocket 14. Furthermore, although the width of the photographic film 30 and the width of the holding pocket 14 are matched as described above, the bottom seal line 1
2 is formed with a slit opening 20A for protruding the corner portion 32 of the photographic film 30, so that loading and unloading of the photographic film 30 is very easy.

FIG. 5 is a diagram showing a second embodiment of the invention. This embodiment shows a holder 10 in which three holding pockets 14 are arranged in parallel. That is, this holder 10 is made up of one transparent plastic sheet 11B having approximately the same shape and size as this holder 10, and three transparent plastic sheets 11A having a shape and size corresponding to the holding pocket 14. However, each holding pocket 14
Focusing only on this, its structure consists of a pair of plastic sheets 11A and 11B, similar to the previous embodiment. In addition, this holding pocket 1
4, it is not necessarily necessary to use two separate plastic sheets 11A, 11B to form the holding pocket 14, but it is not necessary to use two separate plastic sheets 11A, 11B to form the holding pocket 14. Of course, it is also possible to adopt a structure composed of plastic sheets 11A and 11B. In short, it is sufficient that one holding pocket 14 is finally composed of a pair of sheets, one on the front side and the other on the back side.

Furthermore, the materials of the plastic sheets 11A and 11B include polyethylene, polyvinyl chloride,
Any tough transparent plastic film such as polyester or triacetate may be used, and polypropylene is preferred. Note that it is also possible to use paper instead of such a resin sheet. Further, each seal line 12, 13 and regulation seal portions 18A, 18B are formed by being fused by sealing operation such as heat or radio frequency (RF) ultrasonic waves. You can also seal it.

Each holding pocket 14 in this holder 10
As in the previous embodiment, the bottom seal line 1 is
2 are provided with slit openings 20A, 20B, and long and short regulating seal portions 18A, 18B are provided on both sides of the loading port 16, so that photographic film can be loaded in the same manner as in the previous embodiment. It's summery.

The difference from the previous embodiment is that the number of retaining pockets 14 in the holder 10 is different and that the upper part of the holder 10 is provided with a reinforcing strip 24 with punched holes 26. This reinforcing strip 24 is made of a material such as paper or plastic. The punched holes 26 provided in the reinforcing strip 24 can be inserted into a hanging film support bar or inserted into a ring binder or the like.

FIG. 6 is a diagram showing a third embodiment of the present invention. The holder 10 according to this embodiment has holding pockets 1 that are vertically symmetrical around a common loading port 16.
When using the holder 10 in the illustrated state, use the holding pocket 14 below the shared loading port 16 and turn the holder 10 upside down. When using the device, the holding pocket 14 located above the shared loading port 16 (of course located below when in use) is used. Slit openings 20A are formed in the upper and lower bottom seal lines 12 of the loading port 16 on the long regulation seal portion 18A side.

In this embodiment, the regulation seal portions 18A, 18B
, the loading port 16 or the slit opening 20A,
Since they are shared by the upper and lower holding pockets 14, it has a rational structure. The other configurations and effects are the same as those of the previous embodiment, so redundant explanation will be omitted.

<Effects of the Invention> The holder for a photographic article according to the present invention has the content as described above, and has a loading opening that is shorter in length than the photographic article and a width of the photographic article and a holding pocket that are approximately equal to each other. However, since a slit opening is provided on the first regulating seal side of the bottom seal line to allow the corner of the photographic article to protrude, loading and unloading of the photographic article is very easy. be.

Further, since long and short regulating seal portions are provided on both sides of the short loading opening, the photographic article is reliably prevented from falling out of the holding pocket after loading.

Furthermore, since the width of the photographic article and the width of the holding pocket are approximately the same, the photographic article will not be tilted in the holding pocket, and it will be easier to observe the photographic article while it is in the holding pocket. It's convenient.
