Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a film package, and more particularly to a moisture-proof package for a disposable camera having a built-in film in advance.

[Background of the idea]

Generally, it is thought that a photographer carries a camera to a place where he or she wants to take pictures, such as a recreational area or a tourist spot, and takes pictures there. However, cameras are precision instruments and have a certain size and weight, so it may be inconvenient to carry them to sightseeing spots.

Furthermore, when going out to a recreational area or the like, when trying to take a picture, there are cases where the user forgets to carry a camera with him or her.
In such a case, it is not easy to purchase an expensive camera immediately at a resort or the like because there are few stores selling it and it is economical.

So, just like purchasing regular photographic film,
A film unit with a lens can be purchased from a nearby store, and after taking a photo, the photographer can bring the camera along with the camera to a DP store just like traditional photo film.
It would be very convenient if you could request a DPE. In this case, since the camera is special unlike a general camera,
It is preferable that the product be sold in a manner similar to the packaging of color film, giving the impression of a "film", rather than giving the impression that it is an expensive camera. However, in cameras with such systems, even if the film is housed in a case with a simple exposure mechanism, the original moisture-proof packaging is removed and the film is attached to the camera in a ready-to-take state, so there are no problems during the product distribution process. There may be a problem with moisture proofing.

[Purpose of the invention] The present invention was made in view of the above circumstances, and consists of covering a film camera with a paper cover similar in shape to the film outer box, and covering this with a material that has a moisture-proof function. The purpose is to propose a hermetically sealed film package.

[Summary of the idea]

In order to achieve the above object, the present invention maintains a light-tight state in a plastic case body equipped with a photographing mechanism that exposes an image of a subject to light for a certain period of time through a photographic lens through which an unexposed film contained in a light-shielding container is exposed. The case body containing the unexposed film is covered in a rectangular shape with an exterior body made of a paper box with an opening that exposes the photographic lens and the external operation section, and the case body is further covered with a rectangular case body. The outer packaging of the paper box is hermetically sealed with a material that has a moisture-proof function.

[Example of idea]

Preferred embodiments of the film packaging according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a rectangular parallelepiped-shaped camera body 10 and a rectangular parallelepiped-shaped cover 12 in which the camera body 10 is tightly housed. First, the camera body 1
To explain 0, 14 is a photographing lens, 16
18 is a shutter release button, and 20 is a film winding knob. A hole 22 is formed around the photographic lens 14 so as to expand concentrically in a step-like manner, and this stepped hole 22 prevents unnecessary diffused reflection from occurring during photographing. There is. Similarly, the viewfinder aperture 16 is also formed with a step-like step, which prevents diffuse reflection of light and makes it easier to observe the subject. The shutter release button 18 is located within the recess 24 of the camera body 10,
The surface of the shutter release button 18 is flush with the surface of the camera body 10, or its height is set low so that it is located inside the surface of the camera body 10. Similarly, the film winding knob 20
is located in a recess 26 formed on the lower edge of the front surface of the camera, and like the shutter release button 18, the surface of the winding knob 20 is configured not to protrude from the surface of the camera body 10. As a result, the shutter release button 18 and the film winding knob 20
Since the camera body 10 does not protrude convexly from the surface of the camera body 10, the camera body 10 can be smoothly inserted into the cover 12, which will be described later.
can be inserted into the cover 12.

FIG. 2 shows the back of the camera body 10 loaded with 110-inch film, and FIG. 3 is an exploded perspective view showing the camera shown in FIG. 2 with the film removed. As shown in FIGS. 2 and 3, the back surface of the camera body 10 is configured as an open surface 28, and a film storage chamber into which a 110-inch film cartridge 30 is inserted is formed within this open surface 28. A rectangular photographing opening 32 is formed around the photographing lens 14, and a film cartridge 30
When the film cartridge 30 is loaded into the camera body 10, the exposure surface of the film cartridge 30 is positioned in the photographing opening 32. As is well known, a winding gear (not shown) is formed on the film cartridge 30, and when the film cartridge 30 is loaded into the camera body 10, this gear meshes with a gear 34 on the lower side of the camera body 10. It's summery. This gear 34 is connected to the film winding knob 20.
Therefore, by rotating the winding knob 20, the film in the film cartridge 30 can be wound up every time a photograph is taken.

The back surface of the camera body 10 is configured as the open surface 28 as described above, but when the film cartridge 30 is loaded and the pressure plate 36 is provided from the back surface, the exposure surface of the film cartridge 30 is formed in the opening 32. It is pressed against the peripheral edge 38 with a predetermined pressing force, so that regardless of the open surface 28, the exposed surface of the film is completely shielded from light.

Projections 40, 40 are provided at predetermined intervals on the upper end of the pressure plate 36.
is formed, and a protruding piece 42 is formed at the center of the lower end of the pressure plate 36. The protruding pieces 40, 40 at the upper end are inserted into the rectangular gaps 46, 46 on the back of the camera body 10, and the protruding piece 42 at the lower end is inserted into the rectangular gaps 46, 46 on the back of the camera body 10.
It is fitted into the recess 48 at the lower end of the back surface of 0. Pressure plate 36
is made of a thin sheet metal with some elasticity, and by inserting a screw 50 into the screw hole of the protruding piece 42 and screwing the screw 50 into the screw hole 52 in the recess 48, the exposed surface of the film cartridge 30 can be adjusted to an appropriate level. is pressed against the peripheral edge 38 of the photographing opening 32 with a pressing force of
Complete shading. The film pressure plate 36 has a frame number display column 5 of the film cartridge 30.
An opening 54 corresponding to 2 is formed. Further, horizontal grooves 56, 56 are formed on the upper and lower sides of the film pressure plate 36, and these horizontal grooves 56, 56 are used to remove the film cartridge 38 after photographing is completed. That is, in the disposable camera according to the present invention, it is important that the film cartridge 30 can be easily removed at a film processing laboratory. In this case, loosen the screws 50 one by one and remove the film cartridge 30.
Removing the pressure plate would be a complicated task at the DP shop, so with this in mind, the pressure plate can be removed from the camera body 10 by inserting a tool such as a screwdriver into the horizontal hole 56. .

A groove 58 is formed on one side of the back surface of the camera body 10, and this groove 58 is used to remove the film cartridge 30 from the camera body 10. That is, the film cartridge 30 is connected to the pressure plate 36.
Even if the film cartridge 30 is removed, the film cartridge 30 may not be easily removed from the camera body 10 because of the engagement relationship with the gear 34 as described above. Insert a tool such as a screwdriver and remove the film cartridge 3.
0 can be easily removed.

Next, the shape of the cover 12 will be explained based on the developed views shown in FIGS. 1 and 4. Cover 12 is formed from printable cardboard, thin plastic sheet, or the like. In particular, when the main body 10 is covered with a paper box such as cardboard, the paper has a function as a moisture-proofing agent, so when packaging the entire body with a moisture-proof packaging bag as described later, the packaging process must be strictly moisture-proof. Even without it, it has the effect of reducing the humidity inside the bag to the desired level. The cover 12 shown in FIG. 1 is formed by assembling sheets 60 shown in FIG. When the seat 60 is assembled, a rectangular cover 12 that can tightly accommodate the camera body 10 is assembled as shown in FIG. The cover 12 has a circular opening 140 where the photographic lens 14 is located, a rectangular opening 160 where the viewfinder 16 is located, a shutter release button opening 180 where the shutter release button 18 is located, and a winding operation knob 20. An opening 200 is formed in which the opening 200 is located. Further, an opening 161 in which the eyepiece side of the viewfinder 16 is located, and an opening 520 in which the photographed frame display column 52 of the film cartridge 30 is located are formed on the back surface thereof.

The camera body 10 is housed in a paper box or the like constructed as described above with the cover tightly attached. The paper boxed camera body 10 constructed in this manner has a shape as shown in FIG. Next, the camera body 10 is placed in the package 7 under predetermined temperature and humidity conditions.
0 and is fully packaged as shown in FIG.

The layer structure of the package 70 is shown in FIG. 7, in which an aluminum foil 72 is sandwiched between a base material 76 made of polyethylene 74, and an everfilm 78 is formed inside the base material 76 (on the camera side). This Everfilm 78 is used for heat fusion. Further, on the outside of the base material 76, a printing ink layer 82 and a polyester film 8 are coated via an anchor coat 80.
4 is formed.

According to the package 70, the Al foil 72 provides moisture proofing and light shielding functions. Further, since it has the Everfilm 78, its open end can be easily sealed by heat fusion. When packaging a lens-fitted film unit with the packaging body 70, the film is required to be placed under a predetermined humidity condition as described above, and it is desirable that the packaging process be carried out under predetermined temperature and humidity conditions. However, if the lens-equipped film unit is covered with a paper box, the paper box will absorb moisture to some extent.
This has the advantage of being freed from packaging work under strict conditions. After sealing, a hole 86 for hanging at a retail store and a notch 88 for opening are formed as shown in FIG. The open end is deformable and can be folded and displayed when stacked on top of each other at a store, so they can be sold in large quantities like film boxes, making it possible to sell them in a way that is completely different from normal cameras.

[Effect of idea]

As explained above, if a camera is packaged with the film package according to the present invention, it has a moisture-proof function, so that the film will not deteriorate due to moisture during the distribution stage.
