This film-integrated camera has a camera body wrapped in a carton and then covered with a wrapper sheet in a pillow shape. The camera body can be used for shooting while being wrapped in a carton. Used. Then, when the photographing of the entire film is completed, the film is sent to a developing station with the film housed in the camera body, and in the developing station, the cartridge loaded with the roll film is taken out of the camera body and developed.

In this way, a film-integrated camera is discarded when the camera body has finished taking out the film, so it only needs to have the quality and performance enough to take one roll film, and the entire product is manufactured at extremely low cost. It is required to be done.

[Problems to be Solved by the Invention] However, in the above, in order to prevent the influence on the film such as when displayed at a store, the packaging sheet is,
Due to the triple layered structure of polyethylene terephthalate (PET) film on one side of moisture-proof aluminum foil and ethylene-vinyl acetate copolymer (EVA) film on the other side, packaging costs are relatively high. Has become. In particular, since the polyethylene terephthalate film on the outside of the package sheet is printed similarly to the carton,
When the printed package sheet is cut into a pillow shape, the printed pattern must be accurately aligned with the cut position, and complicated work is inevitable.

In addition, the opaque aluminum foil prevents visibility from the outside, making it impossible to directly appeal the aesthetics of the stored camera body to the viewer, and to print it on polyethylene terephthalate film as a pattern or color on the camera body. Had to be displayed.

The present invention has been made in view of such circumstances, and an object of the present invention is to reduce the cost of a film-integrated camera by solving the above problems while maintaining the performance as a package that seals the camera body. To provide

[Means for solving the problem]

According to the above-mentioned object, the present invention provides a package of a film-integrated camera for sealing a camera body in which an unexposed film is previously incorporated, wherein the package is formed of a plurality of layers including a layer having excellent gas barrier properties. It is characterized by being composed of a transparent sheet made of synthetic resin having moisture resistance, as a package having both transparency and moisture resistance, for example,
A three-layer sheet of polyethylene terephthalate (PET) / glass-deposited polyethylene terephthalate (glass-deposited PET) / polypropylene (PP) or polypropylene (PP) / polyvinyl alcohol (PVA) / polypropylene (PP) is used. Among them, glass-deposited polyethylene terephthalate (glass-deposited PET) and polyvinyl alcohol (PVA) have gas barrier properties as well as aluminum foil.

The indicated cartons have been omitted. In the camera body 2, an unexposed roll film drawn from a patrone (not shown) is wound around a film loading chamber provided on the opposite side of the patrone chamber with an exposure frame interposed therebetween.

The camera body 2 includes a photographing lens unit 4 slightly projecting from the front surface, a hole frame type finder 5 penetrating the front and rear surfaces of the camera body 2, and a fixed light emitting unit of a strobe projecting up and down at the upper right corner. 6 and a strobe switch 7 are provided. On the upper surface of the camera body 2, a film counter window 8 and a strobe indicator lamp hole 9 are formed, and a shutter release plate 10 integrated with the camera body 2 is provided. A film winding knob (not shown) is provided.

The camera body 2 winds up the film every time one frame is shot, winds the exposed film into the patrone, and when the predetermined number of shots have been taken, all roll films are stored in the patrone. It is structured to be.

The exposed roll film having taken the desired number of sheets is sent from a user to a processing company in a state of being stored in the camera body 2, and the trader takes out the patrone from the camera body 2 in a light room, and thereafter performs a normal DPE operation. A similar processing operation is performed.

The packaging body 3 is formed by joining both edges of a band-shaped transparent synthetic resin sheet to form a tube conforming to the outer shape of the camera body 2 described above, and housing the camera body 2 therein, and heating both ends. After sealing, the camera body 2 is cut into a predetermined length to seal the camera body 2 in a pillow shape. The material of the package 3 is transparent and moisture-proof, for example, polyethylene terephthalate (PET) / glass-deposited polyethylene Terephthalate (glass deposited PET) / polypropylene (PP),
Polypropylene (PP) / Polyvinyl alcohol (PVA)
/ A three-layer sheet of polypropylene (PP) is used. Among them, the above-described glass-deposited polyethylene terephthalate (glass-deposited PET) and polyvinyl alcohol (PVA) sandwiched in the middle are transparent and have excellent gas barrier properties like aluminum foil.

The film-integrated camera 1 of the present embodiment is configured as described above. When the film-integrated camera 1 is displayed at a store or the like, the camera body 2 is covered by a gas-barrier and moisture-proof package 3. In addition, it is possible to prevent gas, moisture, and the like from entering the package, thereby maintaining good product performance of the camera body 2. Further, since the packaging body 3 is a transparent synthetic resin sheet, the camera body 2 can be visually recognized from the outside while being sealed in the packaging body 3, and the elaborate design of the camera body 2 can be achieved. By using the decoration as it is, the aesthetic feeling can be appealed directly to the viewer.

In addition, since the internal camera body 2 is positively shown in this way, it is not necessary to print on the package 3 as in the related art, and in particular, a pattern or coloring imitating the camera body 2 is unnecessary, The difference between printing and the actual machine can be avoided.

Further, as the effect of making the package 3 transparent, one type of package 3 can correspond to various variations of the camera body, and by omitting printing, complicated positioning of symbols can be performed when cutting the package 3. Since it becomes unnecessary, the cost for packaging can be greatly reduced.

Further, in this embodiment, the carton is omitted from the camera body 2, so that the cost of the entire product can be further reduced.

A film-integrated camera 20 shown in the second embodiment of FIGS. 2 and 3 includes a carton 21 for wrapping the outer periphery of the camera body 2 in addition to the configuration of the camera body 2 and the package 3 of the first embodiment. Be matched.

The packaging body 3 has a transparent window 3a left in a portion corresponding to the photographing lens unit 4, the finder 5, the fixed light emitting unit 6, the strobe switch 7, etc. of the camera body 2, and prints a pattern, a color, etc. on the other part 3b. In this case, the characteristic portion of the camera body 2 is expressed through the transparent window 3a of the package 3 and a masking print is mixed with the characteristic portion to form a characteristic design.

In the second and third embodiments, although the packaging cost is somewhat higher than that of the first embodiment due to the combined use and printing of the carton, the product performance of the camera body in the package is reduced by the gas barrier property and the moisture-proof performance of the package. While maintaining good condition, all or part of the package is made transparent and the camera body is directly visible from the outside, and the camera body is used as a decoration, so that the cost can be significantly reduced compared to conventional products. .

〔The invention's effect〕

As described above, the present invention comprises a package of a film-integrated camera for sealing a camera body, which is formed of a moisture-proof synthetic resin transparent sheet formed of a plurality of layers including a layer having excellent gas barrier properties. Therefore, in the conventional laminated sheet, the product could not be displayed with the opaque glossy skin of the aluminum foil, and it was necessary to apply some printing to the package. Since it is transparent as shown in FIG. 2, printing is unnecessary, and material cost can be kept low especially in small lot production.

Also, when displayed at a store or the like, a package having both gas barrier properties and moisture-proof performance can prevent gas or moisture from entering the package and maintain good product performance of the camera body. It is possible to view the camera body from the outside while the camera body is sealed in the package. Can be appealed directly to the person.

In addition, since the camera body inside the package is positively shown and the camera body is used as a decoration, printing of the package and the carton itself can be omitted. Eliminating the need for complicated pattern alignment work for cutting the body and greatly reducing the cost of packaging can further reduce the cost of the entire product.
