Abstract

PURPOSE:To reduce the space required for recovery and to reduce recycling cost by forming a container body and a cap member of the same resin material. CONSTITUTION:The container body 10 has a container body part 12 having flexibility and a hard mouth part 14 projecting upward from the container body part 12 and these parts are integrally molded by blow molding. A tag 32 for display made of paper indicating contents is freely attachably and detachable mounted on the base part of the mouth part 14. A center plug 31 is freely attachably and detachably mounted in the mouth part 14, by which the upper opening 36 of the mouth part 14 is opened and closed. A cap 30 and the middle plug 31 are formed of the same material as the material of the container body 10. Namely, multilayered constitution mainly composed of low-density polyethylene (LDPE) is used in the case of the container body 10 for liquid, such as developer, requiring a high O2 barrier property, and the LDPE alone is used in the case of the container body for liquid, such as bleaching agent, which does not require the O2 barrier property. Then, the need for a sorting operation is eliminated and the cutting operation while the container body 10 is held attached with the cap member is possible.

FIELD OF THE INVENTION The present invention relates to a container for a photographic processing composition and a method for recycling the same.

[0002]

2. Description of the Related Art Conventionally, high-density polyethylene (HD) has been used as a processing liquid container for a photosensitive material processing device such as an automatic developing device.
PE, polyvinyl chloride resin (PVC), polyethylene terephthalate (PET) and other single layer materials, or nylon / polyethylene (NY / PE) multilayer materials such as blow molding or injection blow molding, which have rigidity Liquid containers were used. This emphasizes the independence of the container, the suitability for filling the liquid in the factory or the suitability for injecting the liquid into the processing tank to make it easy for the user to use, and also the un regulation (export dangerous goods transportation regulation, that is, falling at -18 ° C). This is to ensure the strength that can deal with the legal regulations that take strength into account) and regulations on the transportation of poisonous substances.

However, in the conventional processing liquid container having rigidity, the shape of the container is maintained even after the contents have been discharged and emptied due to its rigidity, which is why after the user uses it. There was a problem that it was difficult to crush when disposing and it was inconvenient to collect.

In order to improve such problems, recently, various flexible containers mainly made of resin such as low density polyethylene (LDPE) have been developed. The inventors have also developed a container of this type and have previously proposed it (Japanese Patent Application No. 5-30664).

[0005]

Not only the conventional rigid liquid container but also the flexible container cannot be a countermeasure against the recent environmental problems by merely crushing it. Also,
Care must be taken in handling the used photoprocessing agent container because the drug is attached to it. In general, a user who uses these treatment agents has a small store space, and if they are simply reduced in volume, they are more likely to be treated as municipal waste and cannot be a real solution. Furthermore, it cannot be said that recycled products are currently used for a wide range of purposes, and a stable market is not secured. That is, there has been a long-awaited demand for providing a recovery method that users can use with peace of mind and an economical and safe recycling method.

At the present time, however, used photoprocessing agent containers have not been reused except in special cases because of the risk of foreign substances from adhering drug. On the other hand, in the case of recycling as a molding material for resin products, if the container and the like are collected with the cap attached, the sorting work between the container and the cap becomes indispensable after the collection, but this sorting work is done manually, and the processing liquid is used during the sorting. There is a problem that the residual liquid of 1) may adhere to clothes and the body, and since the sorting work is difficult to mechanize, the recycling cost becomes high.
Furthermore, the containers actually used are usually attached with a label or the like for indicating the contents, and it is necessary to remove the label, which further increases the recycling cost. .

For these reasons, conventionally, the recycling rate of cutting a container for a photographic processing agent into a molding material for a resin product has not been so high.

However, the limited reuse of earth resources must now be seriously addressed not only in the field of photographic processing agent containers but also in all fields and industries.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a container for a photographic processing composition and a recycling method thereof which can reduce the space required for recovery and the recycling cost. It is in.

It is formed so as to have a maximum protruding portion (hereinafter, referred to as a “maximum circumferential length portion”) that is substantially rectangular in a plan view and protrudes by the same size.

The abacus ball-shaped portions adjacent to each other, that is, the first abacus ball-shaped portion 18, the second abacus ball-shaped portion 20, and the second abacus ball-shaped portion 20.
Abacus ball shape part 20 and a third abacus ball shape part 22, a third abacus ball shape part 22 and a fourth abacus ball shape part 24, a fourth abacus ball shape part 24 and a fifth abacus ball shape part 26 are sequentially connected via rectangular annular connecting portions 28A, 28B, 28C and 28D, respectively.

The second, third and fourth intermediate positions in the height direction
The abacus ball-shaped portions 20, 22, and 24 are equal in height direction dimension above and below the maximum circumferential length portion, and are all formed in substantially the same shape.

As for the dimension in the height direction of the first abacus ball-shaped portion 18 located at the uppermost portion in the height direction, the upper side of the maximum circumference portion is larger than the lower side. On the contrary, the height direction dimension of the fifth abacus ball-shaped portion 26 located at the lowermost position in the height direction is such that the upper side of the maximum circumferential length portion is smaller than the lower side. The height direction dimension below the maximum circumference portion of the first abacus ball shape portion 18 and the height direction dimension above the maximum circumference portion of the fifth abacus ball shape portion 26 are the second, third and fourth abacus. Ball-shaped parts 20, 22, 24
It is approximately half of the height dimension of.

The R portion 18 is provided on the upper and lower portions of the maximum circumference of the first to fifth abacus ball-shaped portions 18 to 26.
A, 18B, 20A, 20B, 22A, 22B, 24
A, 24B, 26A and 26B are formed. These R portions are provided for facilitating volume reduction and more reliably preventing the return to the original shape. Incidentally, these R parts are 5R or more, preferably 15R to 60R,
More preferably, it is desired to be 15R to 40R.

A recess (not shown) is formed on the bottom surface of the fifth abacus ball-shaped portion 26 to improve the stability when the container body 10 is erected.

The mouth portion 14 is formed in a substantially cylindrical shape, and a flange portion 34 having a shape in which both ends of the disc are cut substantially in parallel is provided at an intermediate portion in the vertical direction (height direction) thereof. The mouth portion 14 is integrally formed with the container body portion 12 by blow molding. At this time, since the diameter of the mouth portion 14 is smaller than that of the container body portion 12, the container body portion 12 is formed.
The mouth portion 14 can be formed so as to be thicker, and thus the mouth portion 14 is formed to be hard to some extent. Here, the average thickness of the mouth portion including the mouth portion 14, the flange portion 34, and their vicinity is preferably 0.5 to 4 m.
m, more preferably 0.5 to 3 mm, particularly preferably 1.2 mm to 2.5 mm, and the average thickness of the container body 12 is preferably 0.1 mm to 1.5 mm.
mm, more preferably 0.2 mm to 0.7 mm, particularly preferably 0.3 mm to 0.5 mm, and the difference between them is preferably 0.2 mm, more preferably 0.5 mm. To be Further, it is desirable that the ratio of the average thickness of the mouth portion and the average thickness of the main body portion is about 2.0 to 10.0. By doing this,
The total weight can be reduced without compromising usability.

A male screw portion 14A is formed on the outer periphery of the upper end portion of the mouth portion 14, and a female screw portion which is screwed to the male screw portion 14A is screwed with the cap 30 formed on the inner wall thereof. Has become.

An inner stopper 31 is detachably attached to the mouth portion 14, and an upper opening 36 of the mouth portion 14 is opened and closed by the inner stopper 31. The inner plug 31 is in close contact with the inner peripheral surface of the upper opening 36 of the mouth portion 14 near the opening end,
It has a role of preventing the processing liquid inside from leaking to the outside.

The cap 30 and the inner plug 31 are made of the same material as the container body 10. That is, the cap 30 and the inner plug 31 are referred to as the container body 10 when the container body 10 is formed for a liquid requiring a high O ₂ barrier property such as a developing solution in a photographic processing solution. Same low-density polyethylene / polyvinyl alcohol / ethylene copolymer / low-density polyethylene (LDPE / EVOH / LDP)
E) 3-layer construction, low density polyethylene / nylon (L
It is formed by a multi-layer structure mainly composed of low-density polyethylene such as a two-layer structure of DPE / NY). in this case,
Gas barrier property is 25ml / m ² · day · atm (2
0 ° C 65%) or less, preferably 0.5 to 10 ml / m
Set to ² · day · atm (20 ° C, 65%).

On the other hand, when the container body 10 is formed for a liquid which does not necessarily require an O ₂ barrier property such as a bleaching solution or many fixing solutions, the cap 30 and the inner plug 31 are Low density polyethylene (LD)
PE) alone or an ethylene / vinyl acetate copolymer resin (EVA: in this case, a resin having a density exceeding 0.940 g / cc can also be used). Here, the low-density polyethylene has a density of 0.940 g / cc or less, preferably 0.90 g / cc to 0.940 g / c.
c, more preferably 0.905 g / cc to 0.925 g
/ Cc can be used. The gas barrier property of the container body 10 in this case is 50 ml / m ² · day · a
tm (65% at 20 ° C), for example 100 to 5000 ml
/ M ² · day · atm (20 ° C. 65%).

Since the container body 10 is formed mainly of low-density polyethylene as described above, its weight is also reduced as compared with a container formed of conventional high-density polyethylene (HDPE).

According to the photographic processing composition container 11 of the present embodiment constructed as described above, the mouth portion 14 is relatively hard and the flange portion 34 is formed in a shape in which both ends of the disk are cut out substantially in parallel. Therefore, it is possible to smoothly fill the processing liquid such as the developing liquid and the fixing liquid in the factory. Further, since the mouth portion 14 is relatively hard and the flange portion 34 is easy to hold, the container body portion 12 can be removed when the cap 30 is removed.
(This part is flexible.) Will not be twisted. For this reason, the liquid such as the processing liquid in the container body 10 is erroneously
Inconvenience such as overflowing from 4 is unlikely to occur. In addition, since the container body 10 is characterized by having flexibility, liquid overflow during filling or use is more likely to occur on one side than a conventional container having rigidity, and the liquid filling rate is set to prevent this from happening. It is desirable that the body 10 is pulled to the axial direction and the bellows portion 16 is stretched to the maximum extent of 95% or less, preferably about 95 to 85%.

When the bellows portion 16 is extended,
Since the bellows portion 16 has irregularities, it is easy to hold in the hand, and when the user pours the treatment liquid into the treatment tank, the bellows portion 16 automatically expands and contracts so that the liquid comes out quickly and air entrapment is reduced. This liquid injection is easy to handle and the liquid injection work can be performed smoothly.

In this embodiment, the self-supporting property of the container body 10 is sufficiently ensured by the shape of the container body 12 itself. Further, since the bellows portion 16 is formed in the container body 12, by removing the cap 30 and the inner plug 31 and discharging the processing liquid inside from the mouth portion 14, the amount of the discharged processing liquid can be adjusted. Accordingly, the mouth space 14 can be pressed downward to contract the bellows portion 16 to adjust the head space (the space in the upper part of the container where there is no processing liquid). Since the head space can be adjusted in this way, it is possible to prevent the oxidation by keeping the inside of the processing liquid almost always full.

Furthermore, if the internal processing liquid is discharged to a certain amount or more (substantially the entire amount), the volume can be further reduced by further pressing the mouth portion 14 downward.

The volume reduction of the container in this embodiment means that the pressure required for volume reduction varies depending on the size of the container.
Preferably 1 to 20 kg / cm ² , more preferably 5 to
Was 10 kg / cm ^2, the container volume more than 1 liter, preferably 3~20kg / cm ^2, more preferably refers to what can be reduced in volume at a pressure of about 5 to 10 kg / cm ^2. (The same applies to the following embodiments) Further, by firmly mounting the inner plug 31 and the cap 30 in the volume-reduced state, this volume-reduced state can be maintained. Therefore,
It is possible to improve the collection efficiency of the container body 10 discarded after use.

Here, the volume reduction rate, which is the ratio between the state before the bellows portion 16 is compressed and the state in which the bellows portion 16 is completely compressed, is 50% or less, preferably 40% or less, more preferably 30%. The following is desirable. Here, the volume reduction rate is a volume ratio calculated by utilizing a height change of the water surface when the container body 10 is capped and submerged in water.

The flange portion of the mouth portion 14 has another shape,
For example, it may be formed in a square shape, a hexagonal shape, an octagonal shape, or the like. However, when the mouth portion between the flange portion 34 and the container body portion 12 is lengthened, this portion can be provided, and thus the flange portion 34 may be formed in a circular shape.

It is also possible to provide a cap with an inner plug having a structure such that the inner plug 31 and the cap 30 are integrated, and to form the entire cap with the same low density polyethylene as the container body 10. Further, instead of the inner plug 31 or together with the inner plug 31, another sealing member such as a packing made of the same low-density polyethylene as the container body 10 may be provided.

Next, a method of recycling the container 11 for the photographic processing composition according to the first embodiment will be described. [Recovery Step] The empty photographic processing composition container 11 used for the photographic processing liquid is immediately compressed and reduced in volume and stored in a developing station (or a minilab store). The stored empty container 11 for the photographic processing composition is collected at the collection point for recycling through the collection route specified by the manufacturer. The accumulated product is selected as necessary, and then the process proceeds to the next step. [First Step] With the bellows portion 16 of the container body 10 compressed and reduced in volume, the used photographic processing composition container 11 with the inside plug 31 and the cap 30 attached has the display tag 32. When it is collected in the mounted state, it is hung in a shredder device (not shown) in this state and cut into a predetermined size. [Second Step] A container piece, a cap piece, etc. (hereinafter, referred to as "polymer member") obtained by this cutting are put into a water tank (not shown). As described above, the container body 10 and the inner stopper 3
1, the cap 30 is made of low-density polyethylene whose specific gravity is smaller than that of water, and the display tag 32 is made of paper that sinks in water. The piece of paper, which is a piece of paper, sinks and floats and separates due to the difference in specific gravity.

The polymer member after the washing with water is collected, dried and re-pelletized to be used as a molding material for the packaging material for the photographic processing liquid.

Therefore, according to this embodiment, it is possible to compactly and smoothly collect the used photoprocessing composition containers, which were conventionally difficult for the user to dispose of, from a wide area, and improve the recycling rate. Can be expected. Also,
It becomes possible to automate the sorting step after the collection which has been performed manually, and it is possible to eliminate the possibility that the treatment composition inside adheres to the human body during the sorting operation. In addition, a container body 10 that constitutes the container 11 for the photographic processing composition,
Since the cap 30 and the inner plug 31 are originally made of the same material, it is expected that the quality of the material for molding a resin product obtained by cutting the same is improved.

Incidentally, the container body 10, the cap 30, the inner stopper 3
When 1 is formed of low-density polyethylene, a large number of photographic processing composition containers 11 are collected in a collection bag made of the same low-density polyethylene, and the above-mentioned recycling method is used in the state of being stored in the collection bag. May be carried out.

Further, in the first step (at the time of cutting), in order to significantly reduce the foreign matters mixed in the cutting tip, it may be cut while washing with running water. By doing so, the sulfur deposits that have adhered to the photographic processing composition container 11 are physically removed, and rust can be prevented from occurring on the blade of the shredder device. It also has an effect as cooling water during cutting. Furthermore, a pre-cleaning step using a warm alkaline liquid may be provided between the cutting step and the cleaning step. By doing so, it is possible to specifically remove the oxidatively deteriorated photographic processing composition that is difficult to remove.

Next, a second embodiment of the present invention will be described with reference to FIG. Here, the same components as those in the first embodiment described above are designated by the same reference numerals and the description thereof will be omitted.

The diameter dimension of 6, 58, 60 is 85% or less, preferably 40 to 75%, with respect to the diameter dimension of the maximum diameter portion of the fifth to tenth abacus ball-shaped portions 44, 46, 48, 50, 52.
More preferably, it is desired to be 50 to 75%. This is to improve the folding efficiency and effectively prevent the original shape from being restored when the bellows portion 41 is compressed and the volume of the container main body 42 is reduced after the inner processing liquid is discharged.

Fifth to tenth abacus ball-shaped portions 44, 4
In the upper and lower parts of the maximum diameter parts of 6, 48, 50, 52, R parts 44A, 44B, 4 as shown
6A, 46B, 48A, 48B, 50A, 50B, 52
A and 52B are formed. These R parts 44A to 52
B is formed so as to improve the folding efficiency when the bellows portion 41 is compressed and the volume of the container body 42 is reduced, and it is difficult to restore the original shape by being firmly pushed. In order to achieve this purpose, these R portions 44A to
52B is preferably 5R or more, preferably 15R to 60R, and more preferably 15R to 40R.

A concave portion 52C is formed at the bottom of the tenth abacus ball-shaped portion 52 (bottom portion of the container body 40), thereby improving the stability when the container body 40 is erected.

In this container body 40, the fifth to tenth abacus ball-shaped portions 44, 46, 48, which constitute the bellows portion 41,
Since 50 and 52 have the same diameter as described above, paper or the like can be easily wound around the outer periphery of the bellows portion 41, and both ends of the wound paper can be glued or adhesive. The outer cylinder made of paper can be formed by bonding with.

The cap 70 includes an outer wall 70A and an inner wall 70B.
It has a double cylindrical wall. Outer wall 70A

In the case of the second embodiment, it is possible to further reduce the thickness of the container body 42 (in some cases, the container body 42 itself is made so thin that it is not self-supporting). The part 42 may or may not be self-supporting, but it is preferable that the part 42 is not self-supporting because the volume can be easily reduced. Further, there is an advantage that the outer cylinder is easier to hold in a wound state.

The shrink film (heat-shrinkable film) may be shrunk by heating and brought into close contact with the outer circumference of the container body 42 to form the outer cylinder. Further, in the second embodiment, the case where the bellows part 41 is provided in the entire height direction from the boundary with the mouth 14 of the container body 42 to the bottom is illustrated, but from the boundary with the mouth 14 to the bottom. It is also possible to provide a bellows part in a part of the height direction and to mount the outer cylinder only on the outer circumference of the bellows part. In addition, the shrink film may be pre-cut for easy removal, and the tongue-like piece along with the perforation of a predetermined width (this is the finger when removing the shrink film along the perforation). (Which is a portion to be gripped by) can be provided, and by doing so, the handleability can be remarkably improved.

Next, a method of recycling the photographic processing composition container 41 according to the second embodiment will be described. [Recovery Step] The empty photographic processing composition container 41 used for the photographic processing liquid is immediately compressed and reduced in volume and stored in a developing station (or a minilab store). The stored empty photographic processing composition containers 41 are collected at a recycling point by a collection route designated by the manufacturer. The accumulated product is selected as necessary, and then the process proceeds to the next step. [First Step] The used photographic processing composition container 41 with the cap 70 attached to the container body 40 is collected, and then, in this state, it is mounted on a shredder device (not shown) and cut into a predetermined size. [Second Step] The polymer member obtained by this cutting is put into a water tank (not shown) and washed with water. In this water washing step, the water-soluble adhesive that has attached the label 62 to the polymer member (the container body 40 is cut) is dissolved in water and peeled off from the surface of the polymer member. As described above, the polymer member is made of low density polyethylene or the like, and the label 62
Since the paper is made of paper, the polymer member floats and the paper, which is a cut piece of the label 62, sinks after a lapse of a predetermined time after being charged, and is floated and separated by a difference in specific gravity.

The polymer member after the washing with water is collected, dried and re-pelletized to be used as a molding material for the packaging material for the photographic processing liquid.

Therefore, according to the second embodiment as well, the collection can be carried out smoothly, and the sorting process after the collection can be automated, so that the treatment liquid inside adheres to the human body during the sorting work. It is possible to obtain the same effects as those of the first embodiment, such as eliminating the possibility of causing the above.

In the first and second embodiments described above, the case where the cross section of the container body in the direction orthogonal to the axis is rectangular or circular is illustrated, but the present invention is not limited to this.
The cross-sectional shape of the container body may be formed in an elliptical shape, for example. In this way, when the cross-sectional shape of the container body is elliptical, it is possible to fill a larger volume of liquid than a circular container with the same height and the short radius of the ellipse being the same as its diameter. In addition, even a container having a considerably large capacity (for example, 2 liter to 5 liter) can be grasped by hand. Further, in the case of a photographic processing agent, it is often the case that several types of containers are combined and stored in one box at the same time. The container has less dead space and can be packed efficiently.

The cross section of the container body orthogonal to the axis may be polygonal such as hexagonal or octagonal. In particular, as shown in FIG. 3, the cross section of the container body 61 is hexagonal. In this case, in the case where a large number of them are packed in a box, by arranging them in a so-called honeycomb shape, more efficient packing can be carried out. In the case where the cross section of the container body at a right angle to the axis is hexagonal, if each corner portion is rounded to some extent, boxing becomes easier.

The container body shown in FIG. 3 is similar to the first and second embodiments in that the container body 61 is provided with a total of five abacus ball shapes. The difference is that the parts are arranged concentrically and the diameters thereof are gradually increased from the upper part to the lower part.

The third embodiment of the present invention will be described below with reference to FIGS. Here, the same components as those in the first and second embodiments described above are designated by the same reference numerals and the description thereof will be omitted.

FIG. 4 shows a container 80 for a photographic processing composition according to the third embodiment. The photographic processing composition container 80 includes a container body 82 and a cap 70 that is detachably engaged with the mouth portion 14 of the container body 82.

The container body 82 has a flexible container body portion 84 and the hard mouth portion 14 protruding upward from the container body portion 84. The container body portion 84 and the mouth portion 14 are blow molded. Are integrally molded by.

The container body 84 has a container body 84.
The first and second bellows portions 86 and 88 are formed to expand and contract along the projecting direction of the mouth portion 14, that is, the direction orthogonal to the vertical axis (A-A) direction (direction C and D in FIG. 4). There is.

This will be described in further detail. The container body 84
4 includes a step portion 94 constituted by an arcuate side wall portion 90 on the right side of the paper in FIG. 4 and an axially orthogonal direction extending surface 92 extending outward from the lower end of the arcuate side wall portion 90 in the axial orthogonal direction.
The first bellows portion 86 is formed on the front surface in the arrow B direction below the step portion 94. The second bellows portion 88 is formed on the rear surface in the direction of arrow B from the bottom wall 84A to the top wall 84B so as to face the first bellows portion 86.
The first and second bellows portions 86 and 88 are the container body portion 8
The outer surface and the inner surface of the side wall of No. 4 are formed in a concavo-convex shape alternately along the axis orthogonal direction (arrow C and D directions), and the first bellows portion 86 and the second bellows portion 88 are formed by blow molding. When
It is formed by using a female die whose tip is so-called wavy so that the concave portions and the convex portions face each other.

Further, a handle portion 96 is provided on the container body portion 84 between the upper end of the arcuate side wall portion 90 and the axially extending surface 92, and the handle portion 96 is blow molded. In doing so, it is formed into a relatively thick wall by using a mold.

Although not shown in FIG. 4, the bottom wall 84A is actually formed with a rib for lifting the central portion upward in a curved state, and this rib is, for example, blow-molded by a two-piece mold. It is formed by utilizing the joint portion generated when performing, and thereby the stability when the container body 82 is erected is improved.

A cap 70 is detachably attached to the mouth portion 14, so that the upper opening 36 of the mouth portion 14 is opened and closed. The cap 70 is formed of the same material as that of the container body 82 as in the second embodiment.

A water-soluble label 98 as a water-soluble indicator is adhered to the mouth of the mouth portion 14 of the container 82 by a water-soluble adhesive material. Where the water-soluble label 98
For example, a label made of a material containing polyvinyl alcohol as a main component can be used.

The container 80 for the photographic processing composition of the present embodiment constructed as described above can obtain the same action and effect as those of the first and second embodiments, and since the handle portion 96 is provided, It is easy to hold and easy to handle when the user pours the processing liquid into the processing tank.

The first and second bellows parts 8 are provided on the container body 84.
Since 6, 88 are formed, the self-supporting property of the container body 82 is sufficiently ensured by the shape of the container body 84 itself. In the present embodiment, these bellows parts 86, 8
Although 8 has illustrated the case where it has 3 steps of convex parts as shown in FIG. 4, FIG. 5, the number of the unevenness | corrugation which comprises this bellows part becomes like this. Preferably it is 2-10 pieces, More preferably, it is 4-6 pieces. It is desirable to set the degree.

In this embodiment, the bottom wall 84 of the container body 84 is
Since the rib is formed on A, the container body 82 can be easily folded by using this rib as a fold line at the time of folding. Instead of this rib, a recess which becomes a fold line when folding may be formed.

The outer cylinder 1 as shown by the phantom line in FIG. 4 is obtained by wrapping paper or the like around the outer peripheries of the first and second bellows portions 86 and 88.
If 00 is configured, the self-supporting property of the container main body 84 can be strengthened, and a shrink film (heat-shrinkable film) is used, which is shrunk by heating and brought into close contact with the outer periphery of the container main body 84. You may form an outer cylinder by. By these means, the container body 8 can be formed only by the outer cylinder.
If the self-supporting property of No. 4 is sufficiently secured, it is possible to form the container main body portion 84 itself so thin as to lose the self-supporting property. Even in this case, the cut film may be preliminarily formed in the shrink film for easy removal after use. Also, along with the perforations of a certain width, the tongue (this is
When removing the shrink film along the perforation,
(Which is a portion to be gripped by a finger) may be provided, and by doing so, the handleability can be significantly improved.

In the above embodiment, the case where the handle 96 is formed has been illustrated. However, instead of this handle, the container body 8 is formed.
A concave portion for gripping which can be gripped from both sides may be formed in the mold 4 using a molding die.

Next, the recycling method of the third embodiment will be described. [Recovery Step] The empty container 82 for the photographic processing composition used for the photographic processing solution is immediately compressed and reduced in volume and stored in a developing station (or a minilab store). The empty container 82 for the photographic processing composition is collected at the collection point for recycling through the collection route designated by the manufacturer. The accumulated product is selected as necessary, and then the process proceeds to the next step. [First Step] After collecting the used photographic processing composition container 80 with the cap 70 still attached to the container body 82, a shredder device (not shown) for the photographic processing composition container 80 in this state (see FIG. 5) And cut it to the specified size. [Second Step] The polymer member obtained by this cutting is put into a water tank (not shown) and washed with water. In this water washing step, the water-soluble label 98 and the water-soluble adhesive attached to the polymer member (the container body 82 cut) are dissolved in water. In addition, you may use chemicals, such as alkaline water and an acid, in a washing process as needed.

The polymer member after the washing with water is collected, dried and re-pelletized to obtain a molding material for a packaging material for a photographic processing liquid.

Therefore, according to the third embodiment as well, the collection can be carried out smoothly, and the sorting work after the collection is automated, so that the sorting work by hand is unnecessary.

In the third embodiment, the case where the water-soluble label is used as the water-soluble indicator is illustrated, but the contents are displayed directly on the surface of the container body 82 by the characters written in the water-soluble ink. You may do it.

Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, the photographic processing composition container 41 described above is used. [Recovery Step] The empty photographic processing composition container 41 used for the photographic processing liquid is immediately compressed and reduced in volume and stored in a developing station (or a minilab store). The stored empty photographic processing composition container 41 is collected at the collection point for recycling through the collection route specified by the manufacturer. The accumulated product is selected as necessary, and then the process proceeds to the next step. [Washing Step] The collected container bodies 41, with the cap 70 removed, are thrown into a caustic soda solution tank of about 5% (not shown) with a display attached, and stirred for a predetermined time. Then, it is transferred to a sulfuric acid water tank having a predetermined concentration for neutralization and further washed with water. The container in the volume-reduced state is restored, finished and washed, and then dried. After that, the acceptable product is sent to the product filling process after being judged whether or not it can be used.

The remaining liquid, foreign matter such as sulfur, and the indications that have adhered are completely removed during the treatment with caustic soda liquid and sulfuric acid liquid. Further, the container may be restored at the same time when the cap is removed. As a result, according to the fourth embodiment, similarly to the above-described embodiments, the recovery proceeds smoothly, the re-blowing step can be omitted, and the recycling cost can be reduced.

The first to fourth embodiments are examples of the present invention, and it goes without saying that the shape of the container body is not limited to the shape of the above embodiment. Naturally, the volume-reduction type containers currently on the market have good recovery efficiency. As this type of volume-reducing container, there is a container shown in FIGS. 6 to 8. Of these, the one shown in FIG. 6 is a thin-walled molding container found in mayonnaise and the like, the one shown in FIG. 7 is a container called Bag in Box, and the one shown in FIG. , A pillow type container. Not only the container shown in FIG. 6 but also the containers shown in FIGS. 7 and 8 can be easily recycled by the method of the present invention by using the same material for the mouth portion as the container body.

As the container according to the present invention, any of the above-mentioned containers can be used, but from the above-mentioned various viewpoints, a volume-reducing container comprising a body portion having a bellows structure, a mouth portion and a lid member. Particularly, a container having self-holding property and anti-restoration property (hard to restore) is particularly effective for the recycling method of the present invention.
