Wrapping for packaging light-sensitive Materials.

The invention relates to an envelope for photosensitive material, and more particularly on a packaging for photosensitive material, which also serves as an envelope for mailing of the photosensitive material is used.

In common packaging for photosensitive material, moisture-proofing, light shielding, Shock resistance, non-influencing of the emulsion during the packaging process, storage, circulation, Marketing, use and mailing taken into account. In addition, instructions for use are taken into account, Trademarks, comments on differentiating goods from goods of other manufacturers, effect at Exhibition in the shop window, suitability for the user, quality protection after use and like that.

In order to meet all the requirements that arise from the aspects mentioned above, is one Usual packaging for photosensitive material composed of several packaging materials,

209838/0624

namely:

1. Special accessories = stopper, shock absorbing Material and the like,

2. ID = a dehumidifying material,

3. an inner packing bag = moisture-proof and light-shielding,

4. Usage slip = explanations for use,

5. Post envelope = envelope for sending to the laboratory,

6. outer packaging box = display effect when exhibited in the shop window, Exposure of the company logo, shock absorption,

"7. Film box for return and envelope =

Protection of the developed film.

From the standpoint of simplification and rationalization the packaging process in the factory at the manufacturer, cost reduction in packaging, from the point of view of suitability for the user, etc., ordinary film packages are not always satisfactory.

Accordingly, the main purpose of the present invention is to provide packaging for photosensitive Enhance material such as photographic film.

Another purpose of the invention is to provide a packaging wrapper consisting of a single packaging material is composed and in all working methods of the packaging process can be used until it is returned by post. Yet another purpose of the present invention is to create a packaging wrapper that enhances the quality of the photosensitive Material during storage, circulation, sale, use, mailing and return well protects or maintains, and which

209838/0624

contributes to the rationalization of the packaging process.

Other purposes, advantages and features of the invention will become apparent from the description below, in which the invention is explained with reference to the drawing, for example.

Fig. 1 is a top plan view of a conventional wrapper for mailing the film Development.

FIG. 2 is a top plan view of a photosensitive film wrapper according to FIG the invention.

Fig. 3 is a top plan view of Fig. 2 with a portion of the enclosure opened.
4 is a rear view of the enclosure according to FIG

the invention.

Fig. 5 is a longitudinal sectional view of the enclosure according to the invention,

The appearance of a wrapper according to the invention is essentially the same as the appearance of the conventional return wrapper by means of which the film is sent to the laboratory for processing and further processing by mail. This wrapping has a representation or exhibition print on its surface. As shown in Fig. 5, the paper 13, 13 "of the envelope is provided with a magnificent or glossy print 12, 12 'on its outer surface and with a light-shielding and moisture-proof layer 14, 14' on its inner side. For the paper 13, 13 'paper is used with a board surface and with white surface. the white background area of the paper is provided with the exhibition imprint, and the brown Pappfläche is provided with a polyethylene layer having a thickness of 10 and coated to 20 for the purpose of shielding

209838/0624

to create density against light and moisture.

Furthermore, a cover according to the invention is provided on the inner surface of the moisture-proof layer 14, 14 ^f with plastic fastening parts 5 and 4, which define an area corresponding to the photosensitive material to be packaged. Within the area defined by the plastic fasteners 5 and 4, projections 9, 9 ^{1 are} provided to prevent the fluid wound on a core or spool and engaged therewith from becoming detached. The projections 9, 9 'are made of metal, paper, plastic, wood or the like and are attached to the moisture-proof layer 14'. The general instructions for use of the packaged film are _{printed on the rear surface of the paper 13f} in the area inside the fasteners 4, 5, and this part of the paper can be opened and forms a hinged lid which, by engagement of the interlocking fasteners. supply parts 4, 5 can be closed. An exhibition print is applied to the outer surface, which includes the trademark and other designs.

In Fig. 2, in which an envelope according to the invention is shown in plan view, the envelope for packaging a photographic film is denoted by 1, with 2 a butterfly-shaped sealing part is denoted, while with 3 a hole for fixing the butterfly-like part 2 is denoted . The reference numerals 4, 4 ', 4 "and 5, 5'» 5 "denote relevant half parts of the fastening means which close off the above-described part or hinged cover for holding back the film 15. The completed state of the fastening means is shown in Fig. 5 1ώ step. In the edge part of the envelope, which is designated ι ; -. <. T 6 and 6 ¹ , ·

209838/0624

For example, the front paper and the back paper are attached to one another at the moisture-proof layer 14, 14 "so that the data stamp can be conveniently applied and the envelope as a whole can be made rigid. The edge part 7, 7 ¹ is a closed or sealed part which is formed from sheet material or web material at the time of manufacture of the packaging cover and is provided at its side end with a perforated line 8 for easy opening of the cover. A point for applying a stamp is indicated with, and the reference numerals 11, 11 'denotes a part on which the name and address of the sender can be written.

Fig. 3 shows the envelope according to the invention, the determined by the fastening means 4, 5 Part is open. On the back of this part are usage guidelines or usage instructions for the film, imprinted.

The above-described envelope according to the invention has essentially the same effect as the usual with a single packaging design Packaging system, which is composed of several types of packaging materials, such as has been described above.

When comparing the operations of using the film between one in the usual packaging packaged film and a film packaged in a wrapper according to the invention requires that Open the usual packaging, do the following:

1. Remove the stopper, i.e. that part of the rotation of the core or spool of the film and accordingly prevents loosening of the film wound on the spool,

209838/0624

2. Removal of the slip containing the guidelines for use,

3. Discard the outer box or cover, etc. while the user is in use a casing according to the invention does not carry out these three mentioned operations needs. The only casing according to the invention can be used during storage, circulation, the sale (including exhibition), use and return of the film.

When packaging using the wrapper according to the invention, the following operations must be carried out will:

1. Placing the film in the envelope,

2. Closing the envelope (by closing the lid),

3. Complete closing or locking of the fasteners, and

4. Heat sealing on part 7.

The fastening means open during the rotation of the package and during shipping the envelope does not, and accordingly the film never falls out of the envelope.

In using the film wrapped in the wrapper according to the invention, the following operations are carried out necessary:

1 tearing open the original heat-sealed part 7,

2. Open the envelope of the lid on the fasteners 4, 5, and

3. Remove the film from the envelope. After using the movie are the following

Perform operations:
