Abstract

PURPOSE: To make a photographic processing agent in container flow out even when the container is set at the filling port of a tank in a state where a cap is still attached. CONSTITUTION: An outer cap 34 is attached to the discharge port 30 of a container 24 and the discharge port 30 is hermetically sealed with a seal 46. When the discharge port 30 of the container 24 turns downward and is set to the filling port 36 of a tank 12, a pressing material 42 comes into contact with a projected part 50 formed in the filling port 36 and is pushed up toward the seal 46. Therefore, an edge part 48 formed in the pressing member 42 cuts the seal 46 and the photographic processing agent in the container 24 flows in the tank 12 through the through-hole 44 of the pressing material 42 and the projected part 50. Therefore, the labor and time for unsealing the cap is saved and hands are prevented from being soiled.

On the other hand, a cylindrical body 50 is provided on the bottom surface of the inlet 36.
Are projected and communicate with the tank 12. This cylindrical body 50
The outer diameter of the pressing member 4 is smaller than the inner diameter of the spout 38, and
It is set larger than the two through holes 44. As a result, it is possible to enter the inside of the spout 38 and push up the pushing member 42.

The discharge port 30 is formed with a constricted portion 52 whose diameter is reduced from the outer wall toward the inner wall.
4 limits the amount of processing agent flowing out.

Next, the replenishing mechanism of the photographic processing agent according to this embodiment will be described. As shown in FIGS. 2 and 3, the cap 3
When the discharge port 30 of the container 24 is set downward and set in the injection port 36 with the 2 attached, the pushing member 42 causes the cylindrical body 50 to move.
Then, it is pushed up toward the seal 46. Therefore, the sword portion 48 of the pressing member 42 cuts the seal 46, and passes through the through hole 44 of the pressing member 42 and the cylindrical body 50, and the container 2
The treating agent in No. 4 flows into the tank 12.

Therefore, it is possible to save the trouble of opening the cap 32 and to keep the hands clean.

Next, the replenishing mechanism of the photographic processing agent according to the second embodiment will be described. In the second embodiment, as shown in FIG.
From the top surface of the outer cap 56, a middle cylinder 58 serving as a spout enters into the discharge port 30. This middle cylinder 58
Through this, the processing agent in the container 24 flows out into the tank 12.

An inner plug 62 having a bottom wall 60 is press-fitted into the middle cylinder 58 to seal the middle cylinder 58 so that the processing agent does not leak. A stop plate 64 projects radially from the outer peripheral portion of the bottom wall 60 and is in contact with the end of the middle cylinder 58. The stopper plate 64 functions as a stopper when the inner plug 62 is press-fitted into the inner cylinder 58.

Further, a convex portion 58A is annularly projected on the inner peripheral wall of the middle cylinder 58, and a concave portion 62A fitted to the convex portion 58A is annularly concave on the outer peripheral surface of the inner plug 62. Has been done. The watertightness of the inner plug 62 is improved by fitting the concave portion 62A and the convex portion 58A. The outer cap 5
The top surface of 6 is sealed by a seal 66, which is designed so as to ensure waterproofness and prevent dust and the like from entering the inside plug 62.

On the other hand, a through hole 68 is formed in the center of the bottom wall of the injection port 36. A support plate 72 having a water passage 70 is fixed to the through hole 68. At the center of the support plate 72, a bar member 74 having a length protruding from the injection port 36 is provided upright. An expanded diameter portion 74A is formed at the tip of the cylindrical rod member 74, and when inserted, it is possible to get over the convex portion 62B formed in a circular shape from the inner peripheral wall of the inner plug 62. There is.

The outer cap 56 and the middle cylinder 58 are made of a hard material such as HDPE (high density polyethylene) or P.
The inner plug 62 is integrally formed of P, PET, PVC or the like, and the inner plug 62 is formed of a soft material such as LDPE (low density polyethylene), EVA or rubber. in this way,
By combining members with different hardness, airtightness and sealing performance are improved. Although the inner plug 62 may be harder and the outer cap 56 and the middle cylinder 58 may be softer, the dimensional accuracy of the outer cap 56 and the middle cylinder 58 is ensured, and
In consideration of forming a threaded portion that is screwed with the discharge port 30, it is preferable that the inner plug 62 be soft.

In the case of EVA (copolymer of ethylene vinyl acetate), the softness is adjusted by the content of EV. In this embodiment, the weight percentage is in the range of 3% to 20%, or 5%. It is preferably in the range of -15%.

Next, the operation of the replenishing mechanism of the photographic processing agent according to this embodiment will be described. As shown in FIG. 5, when the discharge port 30 of the container 24 is set downward in the tank 12, the rod 74 provided at the injection port 36 of the tank 12 is sealed by the seal 66.
The inner diameter of the inner plug 62 and the enlarged diameter portion 74
Get over. Further, when it is pushed in, the tip end surface of the rod 72 contacts the bottom wall 60 of the inner plug 62.

Here, when the container 24 is further pushed in,
As shown in FIG. 6, the inner plug 62 is pushed up by the rod member 74, the fitting state between the convex portion 58A and the concave portion 62A is released, and the inner plug 62 is pulled out from the inner cylinder 58.

As a result, the photographic processing agent in the container 24 flows out into the tank 12 through the middle cylinder 58 and the water passage hole 70.

When the container 24 is pulled up from the state shown in FIG. 6, the convex portion 62 is locked to the expanded diameter portion 74A of the bar member 74, and the convex portion 58A and the concave portion 62A are fitted again to each other. Tube 6
2 is sealed with an inner plug 62.

Next, the replenishing mechanism of the photographic processing agent according to the third embodiment will be explained. In the third embodiment, as shown in FIGS. 7 and 8, the top surface of the outer cap 80 screwed into the discharge port 30 of the container 24 is opened to form a spout 82. A circular lid 8 is attached to the edge of the spout 82 via a hinge 84.
6 is attached so that it can be opened and closed. The lid 86 seals the spout 82 of the outer cap 80.

On the hinge 84 side of the lid 86, a contact piece 88 is projected to the outside of the outer cap 80. By pressing the contact piece 88, a rotation moment is generated in the hinge 84, and the lid 86 is opened and closed.

Further, the outer cap 80 and the back surface of the lid 86 are connected by a leaf spring 90. This leaf spring 90 is
A biasing force that draws the lid 86 toward the outer cap 80 is applied.

On the other hand, on the inner wall of the injection port 36, the hanging portion 92
Is protruding. The hanging portion 92 is configured to come into contact with the contact piece 88 protruding from the lid 86 when the cap 94 is inserted into the injection port 36. Also, the hanging portion 9
The inner wall of the injection port 36 located on the opposite side of 2 is provided with an arc-shaped relief portion 98 so that the free end portion of the lid 86 does not come into contact with the opening / closing portion.

Next, the replenishing mechanism of the photographic processing agent according to this embodiment will be described. As shown in FIG. 7 and FIG. 8, when the discharge port 30 of the container 24 is set downward in the tank 12, the contact piece 88 protruding from the hinge side of the lid 86 becomes the hook portion 9.
Upon hitting 2, the hinge 84 is caused to generate a rotational moment in the direction of opening the lid.

As a result, the lid 86 automatically opens against the biasing force of the leaf spring 90, and the processing agent in the container 24 flows into the tank 12 from the pouring port 82. Further, when the container 24 is lifted, the contact piece 88 is separated from the hanging portion 92, and the lid 86 is automatically closed by the biasing force of the leaf spring 90 to seal the spout 82.

Next, the container for the photographic processing agent used in the present invention will be described. The container is used as an inner packaging of the treatment agent in the form of liquid (used liquid type, concentrated liquid type), powder, granules, paste, blended products, tablets and the like. Inner packaging is often a flexible bag,
Distinguished into plastic bottles and back-in-boxes.

The form of the bag is a side seal, two sides
There are three-way seals, envelope type, central joint seal, pleated type, ship bottom seal, flat bottom type, standing pouch type, stick pack, potion pack, and the like. These shapes are 5 in S58 Packaging Technology Handbook (published by Nikkan Kogyo Shimbun).
Examples are described on page 99.

If a notch is formed in these bags, it will be easy to open, and if a zipper type seal portion is provided, it will be easy to use repeatedly. In addition, if a mouth type is provided and it is a cap type, it is convenient for opening and repeated use, and if a handle is attached, handling becomes easy. When these functions are combined and used in this way, the usability for the user is also improved.

The material for the bag is LDP as a single material.
E, HDPE, LLDPE, C-PP, O-PP, PE
As the composite material, T, EVA, or the like is used by laminating various materials (dry laminating or wet laminating), co-extruding, coating, vapor-depositing, or the like according to the application.

The contents of the symbols are the 1989 version of the Glossary of practical plastics (supervised by Susumu Nagai) (Published by Plastics Age Co., Ltd.) P-885-88
It is described in 9.

There is a barrier use as a bag use,
It is often used when antioxidant is required such as in a developing composition, and is preferably 20 ml / day · atm · m ² or less, more preferably 10 ml / day · atm · m ² or less, further preferably 5 ml / day.・ Atm ・ m ² or less, for example, KOP / NY / PE, PE / K

In the case of environmental protection, a material containing no metal, a material having a low burning calorie, or a decomposable material is preferred from the viewpoint of environmental protection. CaCO ₃ (10
It can be reduced compared to PE alone by adding (about 50% equivalent) or making PE into A-PET.

Further, in the film which is decomposed after use, natural polymer such as starch, cellulose and chitosan, microbial polymer using polyester produced by microorganisms such as hydrogen bacteria and cyanobacteria, polylactic acid, PCL (polycaprolactone) and other aliphatic polymers It is preferable to use a chemical system using a synthetic polymer such as polyester, or a resin obtained by blending a decomposition accelerator such as starch with a polyolefin resin. On the other hand, considering recycling, it is important to say that it should be made of a single material as much as possible.

In the case of a special function application, a water-soluble film such as starch is used to wrap a powder chemical and dissolve it in water as it is, so that the user's hands are not soiled and no waste is generated. Moreover, it is preferable to prevent the blocking by adding silicone or the like for improving the slipperiness of the bag.

The composite material is not limited to the above-mentioned examples, and can be widely used by freely combining materials and thicknesses according to the purpose such as function, cost and environment. The thickness often used is 300 µ, and 150 µ or less is often used.

Next, the plastic bottle will be described. Molding methods for plastic bottles include molding methods such as injection, hollow (blowing), injection blowing, and injecting hollow, compressed air, extrusion, vacuum, and the like, and a molding method according to the purpose is adopted. The most commonly used method is hollow molding, and the cap is manufactured by injection molding, and in the case where it is stretched like PET to give strength, injection molding → hollow molding.

In the shape of the plastic bottle, various types such as corners and circles can be formed as a hard type. As the flexible, bellows (vertical / horizontal), thin-walled type (for example, minimum thickness of 0.1 mm) can be used.

As an example of a flexible container, Japanese Patent Laid-Open No.
142394, JP-A-5-30664, JP-A-5-
There is one described in Japanese Patent No. 142399.

In the functional shape, it becomes easier to use if a handle is provided, or if the central portion or the upper portion, and in some cases, the lower portion is recessed to facilitate holding. Further, in the case of being flexible, by shrinking with a paper container or a film so as to have self-reliance, the display can be enlarged and the distinguishability can be improved. In addition, in order to improve the gas barrier property, it is preferable to use double packaging.

As the material of the plastic bottle, HDPE, LDPE, LLDPE, PP, PE are used as a single material.
The composite material of T, PVC, PAN, PA, PC, etc. is prepared by the above-mentioned combination coextrusion molding or the like according to the application.

Examples include PE / PA, PE / EVOH, PE / PA / PE, and the like, and the recycled resin can be used as PE / recycled PE / PE without contacting the work.

Next, the back-in box will be described. The back-in-box can be used for various purposes such as paper containers and cardboard boxes (commonly called BiB) that are integrated with various bags.
As the inner bag of BiB, various materials can be used for the same purpose as the bag.

In the case of a small container, 5 L or less is generally used, and 2 L or less is often used. As an example, there is an example described in S58 Edition Packaging Technical Handbook P-893.

In the case of a box, a paper container is often used, but when strength is required, cardboard (E, B, A, AB flute, etc.) is preferably used.

In the case of the inner bag, the above-mentioned various bags (including types, materials, etc.) can be used as they are. For large containers, generally 5 L or more. An example is described on page 883 of the S58 version packaging technology handbook (published by Nikkan Kogyo Shimbun).

Since the box has a large capacity and a heavy weight, cardboard is often used. It is advisable to make cuts or holes in the top of the box so that the mouth of the inner bag can be fixed.

There are two types of inner bags, a molding type and a pillow type, in terms of form. The molding type has advantages such as a small amount of residual liquid, but has relatively little freedom in selecting materials. On the other hand, the pillow type is the other way around, and there is a high degree of freedom in selecting materials, but there is some residual liquid. However, both materials can be selected in the same way as bags. Further, in the pillow type, since the residual liquid is reduced, it is more preferable to round the upper heat seal part.

Next, a cardboard box as an exterior covering the interior will be described. The format is JISZ1507 (1987
Use various formats specified in (Year), such as A1, A5, B5, B6, etc. Bliss box has high compressive strength and is suitable for heavy objects. In this case, as for the shape of the side pillar, the straight type can further enhance the strength as compared with the so-called frame type.
In addition, hot melt is used because instant adhesion is required when preparing the box, but if cold glue is used together, the adhesive strength will be improved.

As the material, various liners defined in JIS are used by corrugating them in various stages. Use of a water-resistant / water-repellent / water-impervious liner or a liner with a plastic such as PE laminated on the liner can reduce the decrease in compressive strength due to moisture absorption. Naturally, the same effect can be obtained even when used for the core.

As a function addition, in order to increase the strength of the box, the circumference of the box is covered with another cardboard (body frame), or partitions in one direction or crosses are made of cardboard or plastic. When put in, the strength can be greatly increased.

When the interior is flexible and difficult to fix, it is preferable to use a molded article made of expanded polystyrene or the like as a cushioning material or a fixing material for the interior. Recently, environmental problems are great, and it is better to use it instead of styrofoam instead of molding with a pulp mold. Furthermore, recently, a method has been developed in which a metal mold, which is cheaper than a pulp mold, is formed and molded, and one of the methods is to use it.

The photographic processing agent used in the present invention is typically used when developing a silver halide photographic light-sensitive material.

Known photographic processing agents can be used in the present invention. For example, a color developing composition, a black and white developing composition, a bleaching composition, a fixing composition,
A bleach-fixing composition, a conditioning composition, a stable composition and the like can be mentioned.

These treatment agents may be supplied in liquid form, but may be supplied in solid form (eg powder form, granule form, tablet form) or paste form. In the case of a liquid, it may be a concentrated liquid or a used liquid.

The color developing composition used in the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine type color developing agent as a main component. As this color developing agent,
Although aminophenol compounds are also useful, p-phenylenediamine compounds are preferably used, and typical examples thereof include 3-methyl-4-amino-N, N-diethylaniline and 3-methyl-4-amino-N. -Ethyl-N-β
-Hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-N-β
-Methoxyethylaniline and their sulphates, hydrochlorides or p-toluenesulphonates. Two or more of these compounds can be used in combination depending on the purpose.

The color-developing composition comprises a pH buffer such as an alkali metal carbonate, borate or phosphate, a bromide salt, an iodide salt, a benzimidazole, a benzothiazole or a mercapto compound. It is common to include an inhibitor or an antifoggant. If necessary, hydroxylamine, diethylhydrosylamine, sulfite hydrazines, phenylsemicarbazides, triethanolamine, catecholsulfonic acids, triethylenediamine (1,4-diazabicyclo [2,2,2] octane) Various preservatives such as, organic solvents such as ethylene glycol and diethylene glycol, quaternary ammonium salts, development accelerators such as amines, dye-forming couplers, competitive couplers, fogging agents such as sodium boron hydride, 1-phenyl-
Auxiliary developing agents such as 3-pyrazolidone, tackifiers,
Various chelating agents represented by aminopolycarboxylic acid, aminopolyphosphonic acid, alkylphosphonic acid and phosphonocarboxylic acid, for example, ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethylimino Diacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N, N, N-trimethylenephosphonic acid,
Ethylenediamine-N, N, N ', N'-tetramethylenephosphonic acid, ethylenediamine-di (o-hydroxyphenylacetic acid) and salts thereof can be used.

The black-and-white developing composition used in the reversal processing includes dihydroxybenzenes such as hydroquinone,
Known black-and-white developing agents such as 3-pyrazolidones such as 1-phenyl-3-pyrazolidone or aminophenols such as N-methyl-p-aminophenol can be used alone or in combination.

The color developing composition and the black and white developing composition generally have a pH of 9 to 12. The replenishment amount of these developing compositions depends on the color photographic light-sensitive material to be processed, but is generally 1 liter or less per 1 m 2 of the light-sensitive material, and the bromide ion concentration in the replenisher is reduced to 500 or less. It is possible to make the volume even less than 100 ml.

A bleaching process is usually carried out after color development. The bleaching process may be performed simultaneously with the fixing process (bleach-fixing process), or may be performed individually. Further, in order to speed up the processing, a processing method of bleach-fixing processing after bleaching processing may be used. Further, treatment with two continuous bleach-fixing baths, fixing treatment before the bleach-fixing treatment, or bleaching treatment after the bleach-fixing treatment can be optionally carried out. As the bleaching agent, for example, compounds of polyvalent metals such as iron (III), peracids, etc. are used. Typical bleaching agents are:
Organic complex salts of iron (III), such as ethylenediaminetetraacetic acid,
Complex salts of aminopolycarboxylic acids such as diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid and glycol etherdiaminetetraacetic acid; persulfates and hydrogen peroxide can be used. Further, the aminopolycarboxylic acid iron (III) complex salt is particularly effective in both the bleaching composition and the bleach-fixing composition. The pH of a bleaching composition or a bleach-fixing composition using these aminopolycarboxylic acid iron (III) complex salts is usually 5.5 to 8, but a pH of 4 for rapid processing or high silver chloride light-sensitive materials. It can also be processed at 5 to 6.5.

If necessary, a bleaching accelerator can be used in the bleaching composition, the bleach-fixing composition and their pre-bath. Specific examples of useful bleach accelerators are described in the following specifications: US Pat. No. 3,893,858, Western European Patent No. 1,290,812, JP 53-95630.
