Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic processing agent for processing a silver halide photographic light-sensitive material, and more particularly to a photographic processing agent package for packaging a solid photographic processing agent.

[0002]

2. Description of the Related Art In an automatic processor for processing a silver halide photographic material, a photographic light-sensitive material is processed by developing, fixing and washing with water. Here, a developing solution is used for development and a fixing solution is used for fixing. These processing solutions are usually
The temperature is adjusted to 30 ° to 40 ° C, and the photographic light-sensitive material is dipped in these processing solutions for processing. Since these treatment liquids deteriorate with treatment and aging, they are exchanged or replenished with fresh ones by a replenishment method or a patch method before use.

Conventionally, these photographic processing agents are provided in a concentrated liquid form, and users often dilute and use them. The mainstream of these treatment liquids is a packaging form using a plastic bottle as a container.

The liquid state of the photographic processing agent poses a problem in terms of transportation, and a precipitate is produced in the concentrated solution during transportation, which makes re-dissolution difficult.

Also, the used plastic bottle has a problem in disposal. In addition, the other types, such as the concentrated powder type, had a very bad environment for the user during the melting work. If the photographic processing agent is a kitted parts agent, it will be provided in a container such as a bottle or bag, but when the user puts the processing agent in the processing tank, each part agent will be blended without mistake, It was dissolved in advance and added to the treatment liquid, which required skill and manpower.

From such a point, solid processing agents have come to be considered as photographic processing agents which do not require skill and manpower and which do not cause mistakes. In other words, conventionally, a processing agent which has been required to be packaged as a processing agent or prepared as a parts agent is packaged as a single or a plurality of predetermined amounts of a solid processing agent, which is unpacked in a predetermined processing tank or a predetermined processing section when necessary. The supply of the solid processing agent has been studied, and a predetermined amount of the solid processing agent is hermetically sealed in a bag-shaped package as an efficient packaging form capable of automatically supplying the solid processing agent a plurality of times, and The sealed bag-shaped packaging material is in the form of a continuous strip, and if necessary, the sealed portion is opened to take out the enclosed solid processing agent and drop it into the processing tank or processing section.・ Investigation has started to be considered.

[0007]

However, the solid processing agent is sealed in a bag-shaped continuous strip-shaped package, and the sealed portion is automatically opened as needed to encapsulate the solid processing agent. It has been found that there is a problem different from the conventional liquid treatment agent when the agent is dropped and added. That is, even if the package in which the solid processing agent is sealed is cut and opened using a cutter or the like and an appropriate vibration or the like is applied, the enclosed solid processing agent may not fall surely by its own weight. In addition, when the package is cut and opened with a cutter or the like, the solid processing agent contained in the package sometimes interferes and the package is not opened properly.

An object of the present invention is to solve the above problems and to provide a photographic processing agent package suitable for mass production in which a predetermined amount of solid processing agent is surely supplied.

[0009]

SUMMARY OF THE INVENTION The present invention is to solve the above problems, and a predetermined amount of a solid processing agent for processing a photographic material is sealed in a bag-shaped packaging material, and the above-mentioned sealed bag-shaped packaging material is used. In the packaging for photographic processing agents, wherein the packaging is formed in a plurality of continuous strips, and the solid processing agent can be taken out from the sealed portion in predetermined amounts, the coefficient of static friction between the inner surfaces of the packaging material is 0.05 or more 0.4 in an environment of 23 ° C 60% RH
The following is a package for a photographic processing agent: And a predetermined amount of a solid processing agent for photographic material processing is sealed in a bag-shaped packaging material, and the sealed bag-shaped packaging body is in the form of a plurality of continuous strips, and the sealed portion is used to In a package for a photographic processing agent, which is configured so that the solid processing agent can be taken out in a predetermined amount, the waist strength of the packaging material is
It is achieved by a package for a photographic processing agent, which is 15 g / cm or more and 70 g / cm or less. However, the above-mentioned waist strength is based on the repulsive force Wg when a strip-shaped sheet member having a width of Acm is formed into a circular loop by bending a portion having a length of 7 cm and the circular portion is crushed to a thickness of 1 cm. The waist strength is defined as W / Ag / cm.

The tablets were made.

In the strip-shaped package H containing the tablet Z of the solid processing agent of the present invention, a sheet material H1 having a coefficient of static friction between surfaces contacting the tablet Z of 0.05 to 0.4 is used as the sheet material H1. It is the one. Static friction coefficient is 0.05
With the following, the tablet Z is dropped between the two sheet materials H1 and H1 by the automatic heat seal device 300 shown in FIG.
It will be sandwiched and heated at the place corresponding to 301,
At this time, it sometimes happens that the tablet Z slips between the sheet materials H1 and H1 and predetermined heat sealing is not performed. In the experiment conducted by the present inventors, when the static friction coefficient was 0.04, a test was performed in which 2000 times of the tablet Z was dropped by the automatic heat-sealing device 300 to produce a sealed part of 2000 tablets Z. However, the tablet Z slipped four times and the predetermined heat sealing was not performed. Further, when the coefficient of static friction was 0.03, 14 times of defective results were recognized by 2000 times of tests. On the other hand, good results were obtained for all cases where the coefficient of static friction was 0.06.

When the coefficient of static friction is 0.4 or more, when the package H is opened by the rotary cutter 102, especially when the lower edge is cut, the tablet Z does not move in the retreating direction, so that it cannot be opened properly. Sometimes things happened. 20
When the test was performed 00 times, the static friction coefficient was 0.5, and the failure was 5 times. When the static friction coefficient was 0.6, the failure was 16 times. On the other hand, good results were obtained for all under the condition that the coefficient of static friction was 0.3. In this test, it was confirmed that when the tablets Z absorb moisture, an adsorbing force is generated on the inner surface of the sheet material H1 and the number of defective cases is increased as compared with the above test results. Therefore, the above test is a result obtained by confirming that the tablet Z is not in a moisture absorbing state in which adsorption force is generated, but at the same time, it is recognized that the package H is required to maintain a moisture proof state.

The strip-shaped package H containing the tablet Z of the present invention has a waist strength of 1 g / cm or more and 10 g / cm as the sheet material H1.
The sheet material H1 of cm or less is used.
FIG. 8 is an explanatory view of a waist strength measuring method. (A) A strip-shaped sheet member H10 having a width of Acm is bent at the portions indicated by dotted lines on both sides of a 7 cm long portion, and (b) folded. Bent part H10a
Then, the middle 7 cm long part is bent to form a circular loop, and (c) the repulsive force Wg when the circular part is crushed to a thickness of 1 cm is measured, and the waist is measured with W / Ag / cm. Stipulates the strength of. If the waist strength is less than 1 g / cm, a situation occurs in which the dropping of the tablet Z dropping device from 100 is uncertain. That is, the loading device 100 is used to insert the rotary cutter 102
The upper and lower side edges of the sheet material H1 are cut by the sheet material H1, and the bulge of the central portion H1A is emphasized by the peripheral speed difference between the inlet roller R1 and the delivery roller 31, and as shown in the sectional view of FIG. Where tablet Z should fall,
In some cases, the state shown in (b) cannot be dropped due to its own weight. 20 drop test of tablet Z from package H
Although the test was performed 00 times, a drop failure that never occurred when the sheet material H1 having a waist strength of 1 g / cm or more was used was observed in the test at a waist strength of 0.8 g / cm. The occurrence of this drop failure is related to the static friction coefficient of the inner surface of the sheet material H1 and the weight of the tablet Z. Even for the same tablet Z, if the static friction coefficient is 0.05, two drop failures occur, but the static friction coefficient is At 0.4, drop defects were recognized 9 times. Also in this test, when the tablet Z absorbs moisture, an adsorbing force is generated on the inner surface of the sheet material H1, and obviously a fall defect due to moisture absorption occurs. Therefore, the above test is the result of the test performed after confirming that the tablet Z is not in a hygroscopic state in which the adsorption force is generated. From this test, it was confirmed that the package H needs to be kept in a moisture-proof state.

It is also undesirable that the sheet material H1 has a high waist strength. If the stiffness of the sheet material H1 is strong, slippage occurs between the inlet roller R1 and the delivery roller 31 and the sheet material 1 in the above-described test, and bulging is less likely to occur. Further, the package H is stored in the solid processing agent container 15 so as to be folded as shown in FIG. 4, but if the waist strength of the sheet material H1 becomes strong, folding becomes difficult and a large space is required. Was recognized. As a result of making and examining a package H using various sheet materials H1 having different waist strength, it was confirmed that the sheet material H1 has a waist strength of 10 g / cm or less as a practically necessary limit.
