Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for covering a unit body of a lens-fitted film unit.

[0002]

2. Description of the Related Art A film unit with a lens which does not require a troublesome film loading operation, for example, "Sharp Run Hi" (product name) is manufactured and sold by the applicant so that a photograph can be taken immediately after purchase. Have been widely used in general. This lens-fitted film unit is sold at a price that is not significantly different from that of the film alone, so the cost is thoroughly reduced. For this reason, the lens-fitted film unit has a plastic body in which a simple photographing mechanism is incorporated into the film to load the film, and the surface finish is omitted before and after the film, as is known from Japanese Patent Publication No. 32-32615. It has a front cover and a rear cover made of aluminum. The unit itself is wrapped in a beautiful paper box to improve its appearance and is sold as a lens-fitted film unit. The paper box has holes so that the taking lens, the winding knob, the viewfinder, etc. are exposed, and the lens-fitted film unit is used with the paper box covered.

[0003]

By the way, the paper box is assembled by folding a sheet of paper 31 as shown in the development view of FIG. When assembling the paper 31,
The glue margins 32a and 33b of the side surface portions 32 and 33 and the glue margin 34a of the bottom surface portion 34 are the end portions 35 and 36 and the end portions 3 which are indicated by circles.
7 and the end portion 38 overlap each other, and the rear portion 39
The end portions 40 and 41 of are joined together. Therefore, the circle 35,
There are drawbacks that the three parts indicated by 36 and 40 and the three parts indicated by circles 37, 38 and 41 are overlapped to form three sheets, and the thickness becomes thicker than the other parts and the appearance is bad. .. Also, the glue allowance 32 which is inside the glue allowance 34a
Since the a and 33b are not in close contact with the back surface portion 39, there is a drawback that the adhesion state of this portion becomes insufficient. Also,
There is also a problem in that the adhesive margins that overlap when the adhesive margins are folded cannot be folded at the same time, which requires time and effort for both assembly and disassembly, resulting in poor work efficiency.

The present invention has been made in consideration of the above problems of the prior art. The lens-fitted film improves the appearance by reducing the thickness of the overlapping portion of the paper box and improving the work efficiency of assembly and disassembly. The purpose is to provide a unit.

[0005]

In order to achieve the above-mentioned object, the glue margin portions of both side surface portions and the bottom surface portion which are joined to the back surface portion of the package are formed so as not to overlap each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 2 showing the external appearance of a lens-fitted photo film unit, a unit main body 2 is mainly made of plastic and is entirely covered with a package 3. Package 3
Is for cleaning the appearance of the lens-fitted film unit, and a paper box or the like having a printed outer surface is used. The packaging body 3 is provided with holes for exposing a photographing lens 4, a shutter button 5, a winding knob 6, a finder window 7, and a display window 8 for confirming the number of remaining films. It can be done.

The paper package 3 is made by assembling one piece of paper as shown in FIG. 3, and has a bottom surface portion 3a and a back surface portion 3a.
b, the upper surface portion 3c, the front surface portion 3d, and the side surface portions 3e and 3f. The bottom surface portion 3a is provided with a take-out portion 10 for taking out the photograph film cartridge that has been taken, and has perforations 11 formed therein. The glue margin 12 provided at the bottom of the bottom surface portion 3a is formed in a shape in which both end portions 12a and 12b are inclined at about 45 °. Side part 3
Ends 13a, 1 of the glue allowances 13, 14 provided on e, 3f
4a is formed in a shape inclined at about 45 ° similarly to the end portions 12a and 12b so as not to overlap the end portions 12a and 12b of the glue allowance 12. An opening 16 for a viewfinder eyepiece is also formed in the rear surface 3b, and the upper surface 3
In c, an opening 17 for the shutter button 5 and a display window 8 are provided.
Is formed with an opening 18. In the front part 3d,
An opening 19 is formed at a position where the taking lens 4 is provided, and an opening 20 for the finder 7 is formed across the upper surface portion 3c.

The package 3 formed in this way is assembled by folding the one-dot chain line in FIG. 3 into valleys. At that time, as shown in FIGS. 1 and 3, for example, 12 bonding points 21 of the package 3 are provided. First, the unit body 2 is placed on the front portion 3d so that the taking lens 4 and the opening 19 and the finder 7 and the opening 20 are aligned, and the bonding points 21a to 21a.
21c by attaching an adhesive to the bottom surface 3a and the front surface 3d,
Upper surface portion 3c and front surface portion 3d, front surface portion 3d and side surface portions 3e, 3
F and f are folded at right angles. After this, the glue allowance 12, 13, 14
1 is folded along the surface of the rear cover 2a of the unit main body 2, the end portions 12a and 13a and the end portions 12b and 14a do not overlap with each other, as shown in FIG.
3 and 14 are on the same plane. This margin 12, 13, 14
Since the gluing margins 12, 13, and 14 do not overlap each other, the work process of folding can be performed simultaneously or in any order, and work efficiency is good.

Then, after the adhesive is applied to the adhesion points 21d to 21l, the back surface portion 3b is folded in the direction of arrow F and the adhesive margin 1 is applied.
The unit body 2 is packaged by the packaging body 3 by stacking the units 2 and 13 and 14. Thus, the end 12a
Since the end portion 13a, the end portion 12b and the end portion 14a do not overlap with each other, the end portions 23 and 24 of the back surface portion 3b are not high in height and have a good appearance, and the edges of the back surface portion 3b have a margin of glue. Since they are evenly adhered to 12, 13, and 14, sufficient adhesive strength can be obtained. In the lens-fitted film unit thus packaged, the package 3 is not peeled off from the unit main body 2 as long as the photographer uses it in a normal state.

The operation of the lens-fitted film unit constructed as described above will be described. When the photographer confirms that all frames of the film have been photographed by observing the display window 8, he or she operates the winding knob 6 until the film is no longer rotated, so that all the exposed film is stored in the photo film cartridge. Roll up. When the photographer requests the DPE together with the lens-fitted film unit to the development shop, these are further collected at the developing place. Here, the take-out portion 10 provided on the bottom surface portion 3a of the package 3 is peeled off along the perforations 11, the lid of the cartridge chamber is opened, and only the exposed photographic film cartridge is taken out from the unit main body 2.

The photographic film cartridge taken out at the developing station is subjected to print development and printing processing in the same manner as a photographic film cartridge taken by a normal camera. The resulting print photograph is handed to the photographer through a photo shop. On the other hand, the lens-fitted film unit after the photographic film cartridge has been taken out is collected from the developing station by the manufacturer and sent to the disassembling process for reuse.

In order to disassemble the lens-fitted film unit, the packaging body 3 covering the whole is first peeled off. Therefore, since the take-out portion 10 has already been peeled off and adheres to the back surface portion 3b at the bonding points 21i and 21j, the back surface portion 3b is held by holding and pulling the take-out portion 10 in the direction opposite to the arrow F shown in FIG. And glue allowance 12,1
3,14 can be peeled off. After that, if the unit body 2 is pulled out from the package 3, the glue allowance 1
Since the units 2 and 13 and the margins 12 and 14 do not overlap, the unit body 2 and the package 3 can be easily separated.

The peeled package 3 is reused as recycled paper, and the taken out unit body 2 is further disassembled into individual parts for reuse of the lens-fitted film unit. Further, although the packaging body 3 is made of paper in the embodiments described above, a similar effect can be obtained by using a sheet made of another material such as a plastic sheet. Also, the margin 12,1
The end portions 12a, 12b, 13a, 14a of 3, 14 are formed to have an inclination of approximately 45 °, but the present invention is not limited to this, and the end portions 12a, 12b, 13a, 1
As long as 4a does not overlap, it may have any shape, for example, an arc shape.

[0014]

As described above, according to the lens-fitted photo film unit of the present invention, the adhesive margin portions of the side surface portion and the bottom surface portion, which are joined to the back surface portion of the package, are formed so as not to overlap each other. The thickness of the formed portion becomes uniform and the appearance is improved, and sufficient adhesive strength is obtained, which can further contribute to the efficiency of the assembling work and the disassembling work.
