Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a film package for accommodating an X-ray film and performing X-ray photography, and more particularly to a film package suitable for photographing and developing a dental X-ray film.

[0002]

[Prior art]

 The small X-ray film used in the field of dentistry is a package that contains the film inside and seals it from the light.

This X-ray film is put in the oral cavity as it is, photographed, and then taken out from the oral cavity and developed.

Dental X-ray films have hitherto been used so that they can be easily handled at the time of photography and can be developed and fixed without a dark room, for example, as disclosed in JP-B-35-14440. What is enclosed in a synthetic resin bag is used.

That is, the developing solution and the fixing solution are sequentially injected into the bag body after photographing through an injection needle to develop and fix the film, and after the fixing is completed, the film is taken out of the bag and the image is observed.

[0006]

[Problems to be solved by the device]

 However, there are various problems with the package, and for example, it is necessary to pay close attention to inject a processing solution such as a developing solution and a fixing solution into a bag with a thin and sharp injection needle. If this happens, the injection needle would penetrate the bag, and development and fixing could not be performed, and the film that had been photographed at that time would often have to be discarded and re-photographed again, and improvement thereof was strongly desired.

The present invention has been made in view of the above circumstances, and its purpose is to easily inject the image liquid and the fixing liquid into the bag body, and the risk of failure of the work. It is to provide a film package for X-rays that does not have any.

[0008]

[Means for Solving the Problems]

 The X-ray film package of the present invention for achieving the above object has the following constitution. That is, in the upper opening of the bag body 2 formed of the sheets 5 and 6 containing the X-ray film 3, the side edges 7 to 8 are bonded to the side closer to the upper opening than the stored X-ray film 3. A film for X-rays, which has a line 10 and which is formed by forming an adhesive line 11 which is easily peeled off at a position connecting the adhesive line 10 and the side edge 8 and by bonding the front and back sheets 5 and 6 to each other. Achieved by packaging.

According to the present invention, the work for injecting the developing solution into the film package is simple and easy without requiring any special attention, and does not cause failure in development as in the conventional case. Further, by being sealed with an adhesive line, it has the effect of increasing the storage stability of the film itself and preventing the backflow of liquid.

[0010]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a plan view of an X-ray film package of the present invention. Reference numeral 2 includes a bag made of synthetic resin, and an X-ray film 3 housed inside the bag. The bag body 2 is formed of two rectangular sheets 5 and 6 each having an upper edge 4 curved in an arc shape. The sheets 5 and 6 are adhered at the two side edges 7 and 8 and the lower edge 9 by heat sealing, impulse sealing, high frequency fusion or the like (hereinafter simply referred to as adhesion).

In the upper opening of the bag body 2, an adhesive line 10 is formed by linearly adhering the front and back sheets 5, 6 in a direction orthogonal to the two side edges 7, 8. Further, an adhesive line 11 which is easily peeled off is formed at a position connecting the adhesive line 10 and the side edge 8.

An injection opening 12 for injecting a developing solution is formed in the upper left portion of the adhesive line 10 that is easily peeled off in the drawing. It should be noted that the bag 2 is sealed by the adhesive line 10 and has an effect of preventing moisture from getting inside the bag 2 and getting wet.

The adhesive line 11 is formed so as to be easily peeled off by inserting the mouth portions 13 and 14 of the developer container as shown in FIG. 2 into the processing liquid injection opening of the bag body 2. Such adhesiveness should be achieved by reducing the pressure applied during bonding, narrowing the bonding width, or arranging the bonding points in strips, or applying an adhesive that is easy to peel off in strips. Is obtained.

The processing solution injecting opening 12 may have a size such that the opening of the developer container has a gentle conical shape with a circular cross section.

As described above, the X-ray packaging film of the present invention, after the X-ray photography, inserts the mouth 13 or 14 of the developer container shown in FIG. , The adhesive line 11 is pushed toward the adhesive line 11, the adhesive line 11 is peeled off at the tip of the mouth of the container, and the developing solution flows into the entire surface of the X-ray film 3 in the bag body 2.

At this time, it is convenient and wasteful to use a small cartridge type container in which the developer is sealed in advance for one time. After the development process, the sheets 5 and 6 holding the upper edge of the bag body 2 are separated, the adhesive line is peeled off, the bag body 2 is opened, and the X-ray film 3 is taken out to obtain a developed film. it can.

[0018]

[Effect of the device]

 According to the X-ray film package of the present invention, it is not necessary to use an injection needle when injecting the developing solution or the fixing solution into the bag body, and a normal container containing the developing solution or the fixing solution is used. The adhesive line 11 may be peeled off by inserting the mouth portion of the above into the opening portion of the bag and pushing it in.

Therefore, compared with the conventional method, the work of injecting the developing solution and the fixing solution is simpler, special care is not required, and reliable and safe developing and fixing can be performed without breaking the sheet with the needle tip and failing the developing process. Can be done.

Further, it is to prevent the backflow of the liquid at the position of the adhesive line 11 even after the developer is injected. In addition, in the film package before development processing, the inside of the bag body 2 is sealed by the arrangement of the adhesive line, so that moisture can be prevented from entering the inside of the bag body and the deterioration of the storage stability of the film over time can be prevented. Have.

It should be noted that the present invention can be implemented without requiring a great change in the film manufacturing process.
