[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging form of a photographic solid processing agent kit and an automatic liquid preparation device therefor, and more specifically, a solid processing agent kit for photography which can reduce the amount of packaging material to stably and safely prepare a processing liquid. And the automatic liquid preparation device.

[0002]

[Background of the invention]

 In recent years, the amount of waste has increased, and its disposal has become a big problem.

In the field of photographic processing materials, packaging materials such as plastic bottles and bags are used, and it is desired to reduce those materials.

On the other hand, acid, alkali or reducing chemicals are used as photographic processing agents, and it is not preferable that these come into direct contact with hands or bodies. Therefore, it is easy to prepare the liquid, and the packaging form has been devised so that there is no danger, and measures such as using an automatic liquid preparation device have been taken. , CM-50 (manufactured by Konica Corporation) and the like are known, and the user can prepare a liquid without touching any chemicals. In addition, Chem Pact (FUJI, manufactured by HUNT) and the like are known as a liquid preparation device for automatically preparing a solid processing agent.

As an advantage of solidifying the treatment agent kit in this way, the volume of the treatment agent kit can be substantially reduced and the amount of the packaging material used can be reduced. Further, the solid state has the advantage that the mechanical strength of the packaging material can be lowered and the packaging material can be made thinner than the liquid state. Further, air oxidation of the treating agent can be reduced by forming a kit by solidification.

While having many merits as described above, there are the following problems.

That is, when the solid processing agent is charged into the liquid preparation device, if the processing agent is a lump, the solution jumps up at the time of charging, and the acid or alkali processing solution easily adheres to the operator. Alternatively, the manufacturer must open the packaging material and take out the solid processing agent in it.

Further, when the treatment agent is a powder, the powder rises up at the time of addition, and when a person puts it in, there is a risk that the liquid preparation person inhales the chemical. Furthermore, with this device, the packaging material is opened by hand and put in by hand, so there is a danger of contact with chemicals and the possibility of liquid splashing.

Further, in the case of the solid processing agent, chemicals tend to adhere to and remain on the packaging material, and therefore the packaging material cannot be discarded as it is, and it is necessary to wash it. Therefore, the residual of such chemicals changes the composition of the treating agent, and there is a need for urgent improvement also in this respect.

[0010]

[The purpose of the device]

 Therefore, a first object of the present invention is to provide a photographic processing agent packaging form in which the packaging material of the processing agent kit is reduced to reduce the amount of waste. A second object of the present invention is to provide a packaging form of a solid processing agent kit for a photographic product which can stably maintain the composition of a processing solution and can prepare the solution safely, and an automatic solution preparing apparatus thereof. A third object of the present invention is to provide a packaging form of a photographic solid processing agent kit in which used packaging materials can be safely discarded and recycled. Other objects will be apparent from the following specification.

[0011]

[Device configuration]

 The above object of the present invention is: (1) A packaging form for a solid processing agent kit for photographic use, comprising two or more hook-shaped or hole-shaped forms that can be hooked on a part of the packaging material.

(2) The packaging form according to (1), wherein a portion having a lower tensile strength than other portions is provided between the hook-shaped portions or the hole-shaped portions. (3) Two or more members for hooking the hooks of the packaging material, and a mechanism for breaking the packaging material by increasing the distance between the members, for automatic preparation of a solid processing agent for photography apparatus. (4) The automatic liquid preparation apparatus according to item (3), wherein the portion to be broken is below the solid processing agent, and the solid processing agent drops due to gravity when it is broken. (5) Solid processing for photography, which is equipped with a device for cleaning the inside of the packaging material after the solid processing agent is taken out, and whose cleaning water is a mechanism used to dissolve the processing agent. This is achieved by an automatic liquid preparation device for the agent.

Hereinafter, the present invention will be described in detail.

The material of the packaging material that can be used in the present invention is not particularly limited, but polyethylene, polystyrene, paper, etc. are preferably used. Alternatively, a material obtained by vapor deposition of aluminum or coating of polymer on paper, a laminate, or a composite material of materials such as an aluminum sheet may be used.

The hook-like form that can be hooked is a form as shown in FIG. 1, which is provided with a structure in which the automatic liquid preparation device can easily hold and open the packaging material.

The form is not particularly specified, and it is sufficient that the member on the automatic liquid preparation device side is easily caught. This hook-like morphology can be a convenient way to carry the treatment agent at the same time. The number of hooks may be two or more, but two to four are preferable for simplification of the device.

It should be noted that it is one of the preferable modes to attach a pullable portion to the mouth of milk or a sake pack.

An interior may be provided inside the packaging material. As the interior material, a material having low air permeability and low moisture permeability is preferable, and polyethylene is particularly preferable.

Next, regarding the item (2), the automatic liquid preparation device holds the hook-shaped portion and breaks the packaging material by increasing the distance, but when the strength of the packaging material is uniform. Since it is not possible to specify the breakage point and the contents will be scattered, this can be solved by providing a mechanically weak part between the hook-shaped parts.

As a concrete means, when there is an adhesive portion as shown in FIG. 1, the adhesive strength of the adhesive portion is adjusted, the thickness of the packaging material at that portion is thinned, and scratches are made by a sharp object during liquid preparation. It can be achieved by wearing it.

Regarding the mechanism for breaking the packaging material in the following item (3), an example of a specific device is shown in FIG. 2, but the mechanism is not limited to this.

As a method of breaking the packaging material, it is preferable to hold the hook portion of the packaging material by a member that hooks the hook portion of the packaging material and then widen the distance between the members. Various methods may be used to increase the distance, but hydraulic pressure or a motor may be used.

A method of breaking the packaging material by applying a force that widens the distance between the hook-shaped members of the packaging material without changing the distance of the held members is also preferable because it simplifies the device.

According to the present invention, since the portion where the packaging material is destroyed can be formed under the treatment agent, not only can the packaging material be opened, but the contents can be dropped into the liquid preparation tank at the same time. And it can be added to the liquid preparation tank at the same time.

At this time, it is preferable to provide a solution receiving tank with a member that can be received at the dropping position of the treatment agent fixing kit so as to drop directly into the liquid and prevent splashing.

Next, regarding the cleaning method of the item (5), it is preferable to spray water inside the opened packaging material.

Specifically, it is also preferable that a shower nozzle that sprays water in all directions is inserted into the inside of the packaging material for cleaning. Since the shower itself may be powdered, it is preferable that the shower itself can be washed.

A floating lid or floating ball may be used to prevent air oxidization of the treatment agent. In this case, it is preferable that the central portion is raised so that the liquid does not remain on the surface. The dissolution may be completed by measuring the time from the start of dissolution or by measuring the turbidity of the solution. Preferably, the dissolution time is grasped in advance as a function of the temperature of the dissolution water, and control by a microcomputer is time-efficient. Alternatively, it may be detected by pH. Hereinafter, the present invention will be described in more detail with reference to the drawings.
