BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the container of the present invention will be described below with reference to the drawings. In the following description, a photographic film cartridge is used as an item to be stored, but it goes without saying that the embodiment of the present invention can be easily applied to other items to be stored. 1 (a) and 1 (b) are perspective views showing an outline of a photographic film container 1 according to an embodiment of the present invention, in which (a) shows a state before opening and (b) shows after opening. Indicates the state of. This photographic film container 1 has a prism-shaped body portion whose cross section is a square with rounded corners. In order to realize the resealability, the container of the present invention has a tongue piece 11 on an outer shell plate, and a tongue piece tip portion 12 which is a tip of the tongue piece 11.
Can be inserted into the cut end 13 provided in the tubular body 4 after opening.

As shown in FIG. 1 (a), this photographic film container 1 has a cylindrical body portion 4 formed by a body plate 3 and a first seal for sealing both open ends of the cylindrical body portion 4. It is formed by the stop lid 5 and the second sealing lid 7, and the 135 type film cartridge 9 is housed in this container as one embodiment. The body plate 3 is longer than the outer peripheral length of the tubular body portion 4, and has an overlapping portion which is overlapped and adhered to the outside of the tubular body portion 4 with a width ranging from the first sealing lid 5 to the second sealing lid 7. The outer tip of the body plate 3 is formed as a tongue piece 11. When the closed container is formed, the overlapping portion of the body plate 3 is adhered with an appropriate strength, and the container 1 can maintain the moisture resistance. That is, the adhesive strength of the overlapped portion is such that it does not deviate during handling during product transportation, product display, and user storage, but when using a product such as a photographic film stored inside, the tongue piece 11 is not used. When the force of an average adult causes it, the adhesive strength of the overlapping part is such that it can be dissociated and opened. A cut 13 into which the tongue tip 12 can be inserted is provided in a part of the body plate 3 covered with the tongue 11, and the tongue tip 12 of the dissected tongue 11 can be inserted into this cut 13. Thus, the shape of the tubular body portion 4 can be reproduced again. The width of the cut can be selected arbitrarily, but the tongue tip 12 is preferably 35 to 70% of the width of the body plate, and particularly preferably 50 to 60%.

FIG. 2 is a sectional view (a) and a partially cutaway view (b) showing an embodiment of the container according to the present invention before opening.

As shown in the partially cutaway view (b) of FIG. 2, the photographic film cartridge 9 housed in the container is fixed by being sandwiched between the first sealing lid 5 and the second sealing lid 7. Can also be formed. If the second sealing lid 7 is closed while holding the four sides of the tubular body 4 inward rather than the natural state, the tubular body 4 will return to its natural state after the sealed container 1 is completed. In addition, the both sealing lids 5 and 7 are pushed inward, and the photographic film cartridge 9 is fixed in the container 1 by the both sealing lids 5 and 7 in this state. The container 1 according to the present invention has a tubular body portion 4 formed,
After the first sealing lid 5 is formed, the object 9 such as a 135 type film cartridge is housed in the tubular body, and finally the second sealing lid 7 is formed to manufacture the device.

FIG. 6B is a perspective view (b) showing a state of being re-stored. The container 1 according to the present invention includes a tongue piece 11 provided on the outer tip of the body plate.
With the clue as a clue, the package can be opened by pulling it up. That is, the pulling operation can release the adhesion between the body plates 3, and subsequently, the adhesion between the body plate and the first sealing lid 5 and the second sealing lid 7 can also completely separate one side of the square column. It can be pulled off to the state where it does. By such an opening operation, the product that is the object 9 to be stored, in this example, the 135 type photographic film cartridge 9, can be taken out. After the photographing is finished, the photographic film cartridge 9 is re-stored in the opened photographic film container and the tongue tip 12 is inserted into the cut end 13 to reproduce the tubular body shape.

A method of manufacturing the container 1 of the present invention will be described. For the body plate 3 used for manufacturing the container of the present invention, it is preferable to use a laminate in which vapor-deposited layers of metal or inorganic oxide are laminated. The body plate 3 has a cut end 13 before the container is formed.
And the moisture-proof film 15 is attached. The cut 13 may be simply a cut, or may have a certain width at the opening. Furthermore, the periphery of the cut end 13 can be covered from the inside, and the moisture-proof film 15 is heat-sealed to the body plate 3 even outside the body plate so as to cover the cut end of the body plate 3. In this case, it suffices to stick only both sides of the moisture-proof film 15 to the inside of the body plate 3 in parallel with the length direction of the cut from the first sealing lid 5 to the second sealing lid 7. By sealing the first sealing lid 5 and the second sealing lid 7, the sealing in the direction perpendicular to the length direction of the above-mentioned cut is performed. Body plate 3 above

And weakly adhere the inner side of the body plate 3. For this, the body plate 3
It is preferable to provide a sealant layer on either the innermost outermost layer or the outermost layer of the moisture-proof film 15. Although the cross-sectional shape of the tubular body portion 4 is arbitrary, it is preferably a polygon whose corners may be rounded, particularly preferably a quadrangle, a pentagon, a hexagon, etc., and a square with a rounded corner is particularly preferable. preferable. Next, one open end of the tubular body portion 4 is sealed with the first sealing lid 5. Although there are various sealing methods, a sealing lid formed so as to be fitted inside the tubular body portion 4 is fitted into one opening end, and the sealing lid is heat-sealed with the inside of the opening end portion of the tubular body portion 1. Preferably. Next, after the object to be stored 9 is stored in the tubular body portion 4, the other open end of the tubular body portion 4 is similarly closed by the second sealing lid 7, whereby the sealed container 1
Can be manufactured.

FIG. 5 is a cross-sectional view showing an example of the layer structure of a material that can be used in the re-storable container according to the present invention. (A) shows an example of the layer structure of the body plate, and (b) shows the sealing. An example of the layer structure of the lid is shown, and (c) shows an example of the layer structure of the moisture-proof film.

First, the material of the body plate of the present invention is shown in FIG.
A description will be given with reference to (a). The body plate is a gas barrier laminate including a paper layer 20, a printed layer 22 is printed on the outside of the paper layer 20, and the outermost layer is a polyolefin-based thermoplastic such as polyethylene (PE) as a heat seal layer. The resin layer 23 may be provided. Inside the paper layer 20,
A polyolefin-based thermoplastic resin layer 25 such as a PE layer, a gas barrier vapor deposition layer 27, and a (sealant layer or heat seal layer) 29 are sequentially formed.

As the gas barrier vapor deposition layer 27, a vapor deposition layer of a metal or an inorganic oxide can be used, as long as it has a gas barrier property against oxygen, water vapor and the like. Examples of the metal to be vapor-deposited include aluminum and magnesium. In addition, examples of the inorganic oxide to be deposited include silicon oxide, magnesium oxide, aluminum oxide and the like. However, the gas barrier vapor deposition layer 27 of the present invention is not limited to the vapor deposition layer of metal or inorganic oxide, and any material having the above gas barrier function can be used. As these inorganic vapor deposition films, Thin Film Handbook p879 to p901
(Japan Society for the Promotion of Science), Vacuum Technology Handbook p502-
p509, p612, p810 (Nikkan Kogyo Shimbun), Vacuum Handbook revised edition p132-p134 (ULVAC
Japanese vacuum technology K. Inorganic vapor deposition layers such as those described under K) are mentioned. Specific examples include Cr ₂ O ₃ and Si _x O.
_y (x = 1, y = 1.5 to 2.0), Ta ₂ O ₃ , Zr
N, SiC, TiC, PSG, Si ₃ N ₄ , single crystal Si,
Amorphous Si, W, AI ₂ O _{3 and the} like can be mentioned.

Optimum conditions for the thickness of the gas barrier vapor deposition layer 27 differ depending on the type and composition of the metal or inorganic oxide used, but it is generally desirable to be within the range of 15 to 300 nm, and the value is appropriate. You can choose. However, if the film thickness is less than 30 nm, the entire surface of the base material 29 may not be a film, or the film thickness may not be sufficient, and the function as a gas barrier layer may not be sufficiently fulfilled. If the film thickness exceeds 300 nm, it becomes difficult to maintain flexibility in the thin film, and cracks may occur in the thin film due to external factors such as bending and pulling after the film formation. The preferable vapor deposition thickness is 20 to 150 n.
The range is m.

There are various methods for forming the vapor deposition layer 27 made of a metal or an inorganic oxide on the (sealant layer or heat seal layer) 29, and a typical vacuum vapor deposition method is typical, but other thin film forming methods It is also possible to use a certain sputtering method or ion plating method. However, at present, the vacuum deposition method has the highest productivity. In the vacuum vapor deposition apparatus used for the vacuum vapor deposition method, an electron beam heating method or a resistance heating method is preferable as the heating means, and in order to improve the adhesion of the vapor deposition film and the substrate and the denseness of the thin film, a plasma assist method or An ion beam assist method can also be used.

The sealant 29 is composed of a peelable material that can be easily opened. That is, in the unopened state, the sealant 29 is heat-sealed with the moisture-proof film to seal the overlapping portion 17. However, at the time of unsealing, since the adhesive force of the overlapping portion 17 is moderately weak, the adhesive portion of the overlapping portion 17 can be separated. As the sealant 29,
It can be produced using a thermoplastic resin film such as PE as a material, and if necessary, an anchor coat layer as described in JP-A-2000-6304, or JP-A-2001-14.
The shear modulus as described in 5973 is (0.01
˜1) × 10 ⁹ (N / m ² ), a primer layer made of a resin may be provided.

The polyolefin thermoplastic resin layer 25 is
The resin functions as an adhesive layer when the gas barrier vapor deposition layer 27 and the paper layer 20 are bonded by melting the resin in a curtain shape during extrusion lamination. Considering the shrinkage at the time of lamination and workability at low temperature, MFR is 3 (g
/ 10 min) or more is preferable. MFR is 3
If it is less than (g / 10 min), the low-temperature processability is poor and the shrinkage at the time of lamination becomes large, so that cracks may occur in the vapor deposition film and the gas barrier property may deteriorate. Preferably, MFR is 5 to 14 (g / 10min)
It is in the range of.

Polyethylene, polypropylene, ethylene-vinyl acetate copolymers, ionomers and the like can be used for the polyolefin-based thermoplastic resin layer 25, but polyethylene is most preferable in view of extrusion processability.

The temperature at which the above-mentioned polyolefin thermoplastic resin is melted and extruded in a curtain shape is preferably a low temperature at which the gas barrier property of the gas barrier vapor deposition layer 27 is not thermally deteriorated. The kind of resin used and the extrusion thickness Optimal conditions vary depending on the size. 32 for polyethylene
It is preferably 0 ° C. or lower, more preferably 300 ° C. or lower. If it exceeds 320 ° C., the vapor deposition film may be damaged by heat and the gas barrier property may deteriorate. If the temperature is lower than 250 ° C, defects may occur in extrusion processing.
Preferably, melt extrusion is performed in the range of 250 to 320 ° C.

Further, when the extrusion temperature is lower than 260 ° C., the natural oxidation that occurs at the time of free fall from the T-die becomes insufficient and the adhesive strength between the sealant base material and the paper may be weakened. For this reason, it is preferable to forcibly oxidize in order to make up for this deficiency of oxidation, and it is preferable to use surface treatment such as ozone treatment or corona treatment for extrusion lamination in such a case.

As the ozone treatment method, ozone is sprayed on at least one surface of the melted resin so that the temperature of the resin is not excessively lowered or vibrated. As a method for generating ozone, a known method may be used, and for example, it can be easily generated by discharge treatment of air in a closed container,
It can be quantitatively transported by a carrier gas.

The optimum thickness of the polyolefin thermoplastic resin 25 varies depending on the resin composition, the extrusion temperature and the like, but when polyethylene is extrusion laminated at a temperature of 300 ° C. or less, 10 to 20 μm is preferable. Two
If it exceeds 0 μm, the stress when the resin layer is cooled and cured becomes too large, and the strain may be transmitted to the vapor deposition film to cause cracks. If it is 10 μm or less, it may cause a problem in extrusion processing. The preferable resin thickness is in the range of 15 to 20 μm.

The paper layer 20 has a function of imparting strength to the entire container, and is also used as a printing substrate for design printing letters, pictures, drawings and the like. The type of paper is
It can be selected according to the intended function of the packaging material, the printing content, etc., and for example, high-quality paper, kraft paper, coated paper, etc. can be used. The thickness of the paper can be arbitrarily selected according to the purpose of use.

Heat seal layer 23 which may be provided as the outermost layer
Is used as an adhesive portion when forming the overlapping portion 17 of the tubular body portion 4, such as polyethylene, polypropylene,
Resins such as ethylene-vinyl acetate copolymer, ethylene-methacrylic acid copolymer, ethylene-methacrylic acid ester copolymer, ethylene-acrylic acid copolymer, ethylene-acrylic acid ester copolymer and metal cross-linked products thereof. Is used. Although the thickness is determined according to the purpose, it is generally in the range of 15 to 200 μm. Examples of the method for laminating the heat seal layer include known methods such as a dry laminating method in which a film made of the above resin is laminated, a non-solvent laminating method, and an extrusion laminating method in which the above resin is melted by heating and extruded in a curtain shape and pasted.

The material of the first or second sealing lids 5, 7 will be described with reference to FIG. 5 (b). The sealing lids 5 and 7 are also gas barrier laminates including the paper layer 20, the printing layer 22 can be provided on the outer side of the paper layer 20, and the gas barrier vapor deposition is performed on the surface of the plastic substrate 26 on the inner side. The material provided with the layer 27 is laminated by the polyolefin thermoplastic resin layer 25.

The above-mentioned plastic substrate 26 is made of a polymer plastic material and serves as a substrate for vapor deposition. For example, polyethylene terephthalate (PE
T), polyester films such as polyethylene naphthalate, polyolefin films such as polyethylene and polypropylene, polystyrene films, polyamide films, polyvinyl chloride films, polycarbonate films, polyacrylonitrile films, polyimide films, etc. Either way,
Further, those having mechanical strength and dimensional stability are preferable.

These polymer plastic materials are processed into a film and used as a plastic substrate 26. A polyethylene terephthalate film arbitrarily stretched in the biaxial direction is preferably used. In addition, various well-known additives and stabilizers such as antistatic agents, UV inhibitors, plasticizers and lubricants may be used on the surface of the plastic substrate 26 to improve the adhesion to the vapor deposition film. Therefore, as a pretreatment, the surface of the plastic material may be subjected to a corona treatment, a low temperature plasma treatment, an ion bombardment treatment, or a chemical treatment or a solvent treatment.

The thickness of the plastic base material 26 is not particularly limited, but is suitable as a packaging material, has the property of laminating other layers, and forms the gas barrier vapor deposition layer 27. Considering the workability of 3-2
The range of 00 μm is practical, and the range of 6 to 30 μm is preferable. Further, in consideration of mass productivity, it is preferable that the plastic substrate 26 be a long film so that a thin film can be continuously formed.

The gas barrier vapor deposition layer 27 and the polyolefin-based thermoplastic resin layer 25 are the same as those described above with respect to the body plate laminate.

The material of the moisture-proof film is shown in FIG.
Will be explained. In the moisture-proof film, the gas barrier vapor deposition layer 27 is provided on the surface of the plastic substrate 26, and the polyolefin-based thermoplastic resin layer 23 is formed as a heat-sealing layer on one of the surface layers. On the other surface,
It is the layer 28 provided with either one of the (heat seal layer or sealant layer). As described above, in the container of the present invention, one surface forming the easily openable overlapping portion 17 is the sealant layer and the other surface is the heat seal layer. This heat-sealing layer can be provided on either (1) the outermost layer of the body plate, (2) the outermost layer of the moisture-proof film 15 heat-sealed to the body plate, or (3) the innermost layer of the body plate.
