DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for a photographic processing composition, and more particularly to a container for a photographic processing composition suitable as a processing liquid container used for developing a photographic material.

[0002]

2. Description of the Related Art Conventionally, high-density polyethylene (HD)
Rigidity by blow molding or injection blow molding using a one-layer material such as PE), polyvinyl chloride (PVC), polyethylene terephthalate (PET), or a multilayer material such as nylon / polyethylene (NY / PE). A container for the photographic processing composition is used. This makes it easy for the user to use by placing emphasis on 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, and furthermore, the unregulation (restriction on transport of dangerous goods for export, ie, dropping at -18 ° C) This is to ensure sufficient strength to cope with laws and regulations that take strength into account) and regulations on the transport of poisonous substances.

However, this conventional rigid container for photographic processing compositions retains the shape of the container even after the contents are discharged and emptied due to the rigidity. However, there is a problem in that when they are discarded after use, they are not easily crushed and take a relatively large volume.

[0004] In order to solve such a problem, a blow-molded container which can be folded by providing a bellows portion on a body portion and compressing it recently has been developed. According to this foldable blow-molded container, the closed state can be maintained by firmly tightening the cap in the compressed state, so that the collection efficiency when collecting with the cap attached is improved.

[0005]

The above-mentioned conventional blow-molded container has a disadvantage that it easily returns to its original shape when the cap is removed.

On the other hand, recently, it has been considered to reuse a blow-molded container as a material for a resin molded product in order to effectively use limited earth resources. When collecting used containers for the purpose of such reuse, it is necessary to separately collect the cap and the container, which are usually made of different resin materials, and also to reduce the collection efficiency as much as possible. There is. Therefore, for the purpose of reuse, the inventors made various prototypes of bellows containers having various cross-sectional shapes.Then, the diameter of the bellows gradually increased from the top to the bottom of the bellows container with the circular cross-section. Of the container,
It was found that it was difficult to return to the original shape.

On the other hand, usually, a plurality of processing solution containers filled with the same type of processing solution are packed in a box of corrugated cardboard or the like, or are filled with a plurality of types of processing solutions such as a developing solution, a fixing solution, and a bleaching solution. The processing liquid container is packed in the same cardboard box, shipped from the manufacturer and put on the distribution process, but at the time of such boxing, a wasteful space between the containers in the circular divergent container as described above. And the packing efficiency is not good.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a container for a photographic processing composition capable of improving both the collection efficiency and the packing efficiency when collected separately from a cap. Is to do.

SUMMARY OF According to the container for photographic processing composition according to claim 1, the container body is molded integrally with the neck portion by blow molding, the bellows portion is disposed at a predetermined distance along the axial direction of the container body And since the axis orthogonal cross-section having an annular maximum protruding part of the arrangement and size overlapping in the axial direction at the axial middle part is provided with a plurality of substantially rectangular annular convex parts, when packing a plurality of boxes, There is almost no dead space between containers. In addition, since the bellows portion includes a band-shaped annular connecting portion that connects the adjacent annular convex portions with the minimum projecting portions in the axial orthogonal direction at both axial ends, blow molding is performed. during the ring-shaped connecting portion of this it is formed thicker than the annular convex portion. In addition, since one of the upper and lower axial dimensions of the annular maximum protruding portion of each annular convex portion is larger than the other, the bellows portion is formed by pressing the mouth portion in the axial direction. The other side portion of the annular maximum projection of each annular projection is recessed toward one side and enters inside the one side portion of the annular maximum projection. In addition, the axis is determined based on the maximum annular projection of each annular projection.
The outer peripheral surfaces on one side and the other side are formed to be curved.
Therefore, by pressing in the axial direction, the upper or lower side
The outer peripheral surface is inverted and recessed on the lower or upper outer peripheral side,
Attempt to maintain a recessed state. As a result, the volume of the container body is reduced by being compressed, and it is difficult to return to the original shape after the volume is reduced.

In this case, in the case where each of the annular projections and each of the annular connecting portions have an octagonal shape obtained by removing substantially the same triangular portion from a rectangular square, the rectangular square portion and the other portions are formed. Because the difference in distance from the central axis to the part is smaller, the resin easily wraps around the square part during blow molding, and the thickness of the cross section perpendicular to the axis is closer to a uniform state, further reducing the volume It becomes difficult to return to the original shape after formation.

According to the container for photographic processing composition according to claim 2, based on said annular maximum protruding portions of the annular projection
The radius of curvature of the outer peripheral surface on one side in the axial direction is
Since it was smaller than the rate radius, by pressing the mouth portion in the axial direction, recessed toward the other side portion on one side of the annular maximum protruding portions of the annular convex portion constituting the bellows portion, the maximum cyclic It penetrates deeper inside the one side portion of the protrusion.
Thus, the volume of the container body is further reduced by being compressed, and it becomes more difficult to return to the original shape after the volume is reduced.

According to the container for a photographic processing composition according to the third aspect , when a plurality of boxes are packed for the same reason as the container for a photographic processing composition according to the first aspect , the distance between the containers can be reduced. Almost no dead space. Further, as in the case of the container for a photographic processing composition according to the first aspect , at the time of blow molding, the annular connecting portion is formed to be thicker than the annular convex portion. Moreover, with respect to the annular maximum protruding portions of the annular projection
Step on the outer peripheral surface on one or the other side in the axial direction
Since Jo grooves) are formed by pressing the mouth portion in the axial direction, of the one axial side or the other side of the annular maximum protruding portions of the annular convex portion constituting the bellows portion, the outer peripheral surface To step
Each annular projection portion parts are formed side is recessed toward the side where the stepped portion is not made form <br/> an outer peripheral surface, the inner side of each annular protrusion portion of the non stepped portion is formed on an outer circumferential surface side Get in. This allows
The container body is easily compressed and reduced in volume, and it is difficult to return to the original shape after the volume is reduced.

The radius of curvature of the R portion 22A is greater than the radius of curvature of the R portion 22B, the radius of curvature of the R portion 24A is greater than the radius of curvature of the R portion 24B, and conversely, the radius of curvature of the R portion 18A is R The radius is smaller than the radius of curvature of the portion 18B. The radius of curvature of the R portion 26A is substantially equal to the radius of curvature of the R portion 26B.

The radius of curvature of these R portions is 5 mm or more,
Preferably 15 mm to 60 mm, more preferably 15 m
m to 40 mm.

Further, the maximum diameter of the first annular connecting portion 28 is set to 85% or less, preferably 40 to 75%, more preferably 50 to 75% of the maximum diameter of the first annular projection 18. , The second annular connecting portion 30 is connected to the second annular convex portion 20.
And the third annular connecting portion 32 has a similar relationship to the third annular convex portion 22, and the fourth annular connecting portion 34 has the fourth annular connecting portion 34. It is preferable to make the same relationship with the annular convex portion 24 in order to improve the folding efficiency.

As is clear from FIG. 1, the first, second, third and fourth annular connecting portions 28, 30, 32 and 34 are provided.
Are first, second, third, fourth, and fifth annular convex portions 18, 2
Since the projecting length in the direction perpendicular to the axis from the central axis AA is smaller than 0, 22, 24, and 26, the first, second, third, fourth, and fourth parts are formed when blow molded using a parison having a circular cross section. The fifth annular projections 18, 20, 22, 24, 26 are formed to be somewhat thicker.

The mouth portion 14 is formed in a substantially cylindrical shape, and a cross-sectional shape in which both ends of a circle are cut in parallel so as to have the same chord length is formed at an intermediate portion in the vertical direction (axial direction) (see FIG. 2). Is provided. The mouth 14 is formed integrally with the container body 12 by blow molding using a parison having a circular cross section. At this time, since the diameter of the mouth 14 is smaller than that of the container body 12, 12
The opening 14 can be formed to be thicker, and thus the mouth 14 is formed to be somewhat hard. Here, the average thickness of the mouth portion including the mouth portion 14, the flange portion 44 and the vicinity thereof is preferably 0.5 to 4 m.
m, more preferably 0.5 to 3 mm, particularly preferably 1.2 to 2.5 mm, and the average thickness of the container body 12 is preferably 0.1 to 1.5 m

The difference between the two is preferably 0.2 mm, more preferably 0.1 mm.
It is set to about 5 mm. Further, the ratio between the average thickness of the mouth portion and the average thickness of the main body is desirably about 2.0 to 10.0. By doing so, the total weight can be reduced without impairing the usability.

On the outer periphery of the upper end of the mouth portion 14, a male screw portion 1 is provided.
4A is formed, and a female screw portion screwed to the male screw portion 14A is screwed to a cap (not shown) as a lid member formed on the inner wall thereof so that the upper opening of the mouth portion 14 is opened and closed. Has become. The cap is formed of, for example, low density polyethylene (LDPE), polypropylene or high density polyethylene (HDPE). Here, as the high-density polyethylene, for example, a density of 0.9
More than 40 g / cc, preferably 0.940 g
/ Cc and 0.98 g / cc or less, more preferably 0.945 g / cc to 0.97 g / cc. Also, as low-density polyethylene,
Density 0.940 g / cc or less, preferably 0.90 g / cc
cc to 0.940 g / cc, more preferably 0.905
g / cc to 0.925 g / cc can be used.

If gas barrier properties are required for the photographic processing composition container 10 depending on the liquid to be filled, the necessary gas barrier properties can be easily provided by changing the materials and raw materials used. For example, among photographic processing liquids, when formed for liquids requiring a high O ₂ barrier property, such as developing solutions, low density polyethylene / polyvinyl alcohol / ethylene copolymer / low density polyethylene (LDPE / EVOH) / LDPE) and low density polyethylene / nylon (LDPE / N)
Y) It has a multi-layer structure mainly composed of low-density polyethylene, such as a two-layer structure, and has a gas barrier property of 25 ml.

On the other hand, when the photographic processing composition container 10 is formed for a liquid which does not necessarily require an O ₂ barrier property, such as a fixing solution, for example, low density polyethylene (LDPE) alone or ethylene / acetic acid is used. It is formed using a vinyl copolymer resin (EVA: in this case, a resin having a density exceeding 0.940 g / cc can 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

5 g / cc can be used. The gas barrier property of the photographic processing composition container 10 in this case is 50 ml.
/ M ² · day · atm (65% at 20 ° C), for example 1
00 to 5000 ml / m ² · day · atm (20 ° C
65%).

Since the photographic processing composition container 10 is formed mainly of low-density polyethylene as described above,
It is lighter in weight than containers made of conventional high density polyethylene (HDPE).

According to the photographic processing composition container 10 of the present embodiment constructed as described above, the mouth portion 14 is relatively hard, and the flat surfaces 44A, 44 parallel to the flange portion 44.
Since B (see FIG. 2) is formed, the filling operation of the processing liquid such as the developer and the fixing liquid in the factory can be performed smoothly. Also, the mouth 14 is relatively hard and the flange 44
It is easy to hold the container body 1 when removing the cap.
2 (this part is flexible) does not twist.
For this reason, inconveniences such as a liquid such as a processing liquid in the photographic processing composition container 10 erroneously overflowing from the mouth portion 14 hardly occur. In addition, since the photographic processing composition container 10 is characterized by having flexibility, liquid overflow during filling or use is more likely to occur on one side than a rigid conventional container,
To prevent this, it is desirable that the filling rate is 95% or less, preferably about 95 to 85% of the state in which the bellows portion 16 is extended to the maximum by pulling the container 10 for a photographic processing composition in the axial direction.

When the bellows 16 is extended,
Since the bellows part 16 has irregularities, it is easy to hold in the hand, and when the user pours the processing liquid into the processing tank, the bellows part 16 automatically expands and contracts, so that the liquid comes out quickly and air entrapment is reduced, The handling at the time of the injection is easy, and the injection operation can be performed smoothly.

In this embodiment, the first to fourth annular connecting portions 28 to 34 are formed to be thicker than the first to fifth annular convex portions 18 to 26 at the time of blow molding. By the shape 12 itself, the autonomy of the container 10 for photographic processing composition is sufficiently ensured.

Further, since the first to fifth annular projections 18 to 20 constituting the bellows portion 16 of the container main body 12 are arranged and sized so as to be overlapped when viewed from the axial direction, the photographic processing composition can be used. When a plurality of containers 10 are packed in a box, a dead space hardly occurs between the containers 10 for photographic processing compositions. The axial dimension of the lower part of the second to fifth annular convex parts 20 to 26 is larger than that of the upper part of the maximum annular convex part, and the R part formed on each annular convex part has the above-mentioned dimension. And the second to fifth annular projections 20 to
Since the first to fourth annular concave grooves 36 to 42 are formed on the upper peripheral edge near the annular maximum protruding portion 26, pressing the mouth portion 14 in the axial direction allows the second to fifth annular grooves to be pressed.
The upper portion of each of the annular maximum projections of the annular projections 20 to 26 is recessed downward and enters inside the lower portion of the annular maximum projection, and finally, as shown in FIG. Is done. The volume reduction rate will be described later.

The volume reduction of the container in the present embodiment differs depending on the size of the container.
20 kg / cm ² , more preferably 5 to 10 kg / cm
² , in a container having a volume of 1 liter or more, preferably 3 to 20 kg / cm ² , more preferably 5 to 10 kg.
/ Cm ² means that the volume can be reduced (the same in the following examples).

Further, by removing the cap and discharging the internal processing liquid from the opening 14, the opening 14 is pressed downward in the axial direction according to the amount of the discharged processing liquid to shrink the bellows part 16. To adjust the head space (the space in the upper part of the container where there is no treatment liquid). As described above, since the head space can be adjusted, it is possible to prevent the oxidation by making the internal processing liquid always substantially full.

Further, in this photoprocessing composition container 10, since the various parts of the bellows part 16 are configured with the characteristics of the dimensions and thickness of the various parts described above, the folding shown in FIG. In this state, even if the cap 38 is removed, it does not return to its original shape, and even if it is collected separately from the cap after use for the purpose of reusing as a material of a resin molded product, the collection efficiency is improved. Can be improved.

Here, the volume reduction ratio, which is the ratio between the state before the bellows part 16 shown in FIG. 1 is compressed and the state shown in FIG. 3 when the bellows part 16 is completely compressed, is preferably 50% or less, and more preferably 50% or less. Is preferably at most 40%, more preferably at most 30%. However, this ratio may be 10% or more,
It is preferable in terms of manufacturing and design. Here, the volume reduction ratio is a volume ratio calculated using a change in the height of the water surface when the photographic processing composition container 10 is capped and submerged in water.

Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 4 shows a container 50 for a photographic processing composition according to the second embodiment.

The photographic processing composition container 50 has a flexible container main body 52 and a hard mouth 54 projecting upward from the container main body 52.

The first to fifth annular projections 58 to 66
Each of the fifth to eighth annular connecting portions 68 to 74 has an octagonal shape obtained by removing substantially the same triangular portion from a rectangular square in a cross section orthogonal to the axis (see FIG. 5). First,
The second , third , fourth , and fifth annular convex portions 58, 60, 62,
The annular maximum projections 64 and 66 are provided at the intermediate portions in the axial direction (vertical direction), each of which has an annular maximum protruding portion projecting in the direction perpendicular to the axis from the central axis Z-Z, which has a size and arrangement overlapping when viewed from the axial direction. ing. The axial dimension of each of the first , second , third , fourth , and fifth annular projections 58, 60, 62, 64, 66 is substantially equal between the upper side and the lower side of each of the annular maximum projections. ing. That is, in FIG. 4, a ₆ ≒ b ₆ , a ₇ ≒
b ₇ , a ₈ ≒ b ₈ , a ₉ ≒ b ₉ , and a ₁₀ ≒ b ₁₀ .

The first, second, third, fourth, and fifth annular projections 58, 60, 62, 64, and 66 are provided on the upper side of the vicinity of the annular maximum protruding portion along the entire periphery. And relatively shallow fifth, sixth, seventh, eighth, and ninth annular concave grooves (steps) 76,
78, 80, 82 and 84 are formed.

The first , second , third , fourth , and fifth annular projections 58, 60, 62, 64, and 66 have R portions 58A on the upper side and the lower side of the respective annular maximum projections. , 58B,
60A, 60B, 62A, 62B, 64A, 64B, 6

The radii of curvature of A, 64B, 66A, and 66B are substantially the same. The radius of curvature of the R portion may be different between the upper and lower portions of each annular maximum protrusion.

The radius of curvature of these R portions is 5 mm or more,
Preferably 15 mm to 60 mm, more preferably 15 m
m to 40 mm.

Further, the maximum diameter of the fifth annular connecting portion 68 is set to 85% or less, preferably 40 to 75%, more preferably 50 to 75% of the maximum diameter of the first annular projection 58. , The sixth annular connecting portion 70 is the second annular convex portion 60.
And the third annular connecting portion 72 has a similar relationship to the third annular convex portion 62, and the eighth annular connecting portion 74 has the fourth annular connecting portion 74. It is preferable to make the same relationship with the annular convex portion 64 in order to improve the folding efficiency.

As is apparent from FIG. 4, the fifth, sixth, seventh, and eighth annular connecting portions 68, 70, 72, 74 have
1st , 2nd , 3rd , 4th , 5th annular convex portions 58, 60, 6
Since the projecting length from the center axis Z-Z in the direction perpendicular to the axis Z-Z is smaller than that of 2, 64, 66, the first , second , third , fourth , and fifth parts are blow-molded using a parison having a circular cross section. Are formed to be somewhat thicker than the annular convex portions 58, 60, 62, 64, 66. In the second embodiment, since the components constituting the bellows portion 56 are formed in the above-described cross-section orthogonal to the axis, the resin easily flows around the rectangular portion during blow molding. The thickness of the cross section becomes closer to a uniform state. At the time of blow molding, the parison control may be performed using a so-called parison controller and a deformed die so as to make the wall thickness more uniform.

The mouth 54 is the mouth 14 in the first embodiment.
In the same manner as described above, it is formed integrally with the container body 52 by blow molding. At this time, the portion of the mouth portion 54 is formed so as to be hardened to some extent. The mouth 54
Is formed in a substantially cylindrical shape, and a flange portion 86 having a cross-sectional shape (see FIG. 5) in which both ends of a circle are cut in parallel so as to have the same chord length is provided at an intermediate portion in the vertical direction (height direction). Is provided. Here, the average thickness of the mouth portion 54, the flange portion 86, the connecting portion 52A, and the vicinity thereof is preferably 0.1 mm.

The average thickness of the container body 12 is preferably 0.1 mm to
1.5 mm, more preferably 0.2 mm to 0.5 mm,
Particularly preferably, it is formed so as to have a thickness of 0.3 mm to 0.7 mm, and the difference between the two is preferably made 0.2 mm, more preferably about 0.5 mm. The ratio of the average thickness of the mouth to the average thickness of the main body is 2.0 to 10.
It is desirable to set it to about 0.

A male screw portion 54A is formed on the outer periphery of the upper end of the mouth portion 54 similarly to the mouth portion 14 in the first embodiment, and a female screw portion to be screwed with the male screw portion 54A is formed on the inner wall thereof. The cap (not shown) is screwed.

The photographic processing composition container 50 is formed of the same material as the photographic processing composition container 10 in the first embodiment.

According to the second embodiment constructed as described above, the same or equivalent operation and effect as those of the first embodiment can be obtained. Since the thickness is almost uniform over the entire periphery, it is more difficult to return to the original shape after the volume is reduced.
