Abstract

PURPOSE:To easily perform developing processes without damaging an X-ray film, by forming a passage in the clearance between the 2nd sheet section and 3rd sheet section and blocking the passage by means of a blocking section. CONSTITUTION:The 2nd sheet 6 and 3rd sheet 7 are deposited along inclined lines 8a and 9a and folded lines 8b and 9b, respectively, and a passage 10 is formed between the inclined lines 8a and 9a, a blocking section 12 provided at the halfway of the passage 10 is formed by bonding the 2nd and 3rd sheets 6 and 7 with each other by means of a bonding agent of a weak bonding power across the passage 10. An X-ray film 1 is completely shielded from the outside and closely enclosed by means of the 1st, 2nd, and 3rd sheets 5, 6, and 7. When a developing solution is sucked into an injector and the needle of the injector is inserted into the passage and, when the pointed end of the needle reaches an opened section 11, the developing solution is discharged, the developing solution penetrates to the lower surface of the X-ray film 1 from each edge section and developing is performed. Injection of a fixer is also performed in the same way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a package for sealing a film used in X-ray photography, and particularly to an X-ray film package suitable for dental X-ray film.

[Prior art to the invention]

The X-ray film package is composed of an X-ray film and a package that prevents the X-ray film from being exposed to light. This will be explained using a diagram.

FIG. 3(a) is a plan view of a conventional dental X-ray film package, and FIG. 3(b) is a sectional view taken along line mb-mb in FIG. 3(a). In the figure, 1 is an X-ray film, 2 is a flexible synthetic resin sheet that covers the top surface of the X-ray film 1, and 3 is a flexible synthetic resin sheet that covers the bottom surface of the X-ray film 1. The sheet 2.3 is made of synthetic resin that does not transmit light. Edges 2a, 2b, 2c of sheet 2 and sheet 3
edges 3a, 3b.

3c are welded together to form a bag, and the X-ray film 1 is housed within this bag. 2d, 3
d is a welded portion of the filter sheet 2.3 at the edge of the X-ray film, and by welding these welded portions 2d and 3d together, the X-ray film l is sealed in the bag. 2e,
Reference numeral 3e indicates a tongue piece projecting outward from the welded portions 2d and 3d.

In use, this X-ray film package is brought into contact with the affected area in the patient's oral cavity, and X-rays are irradiated from the outside. As a result, an X-ray image (latent image) of the affected tooth is obtained on the X-ray film 1. After X-ray irradiation, the X-ray film package is removed from the oral cavity and subjected to development processing. This development process is performed as follows. That is, first, the developer is sucked into the cylinder of the syringe, and then the needle of the syringe is inserted into the sheet l.
Alternatively, the sheet 2 is pierced at an appropriate location, its tip is inserted into the bag, and the developer in the cylinder is injected into the bag. After injection, the entire X-ray film package is rubbed to bring the developer into sufficient contact with the entire X-ray film to prevent uneven development. A fixer is injected by similar means to fix the X-ray image. Finally, the X-ray film 1 is taken out by pulling the tongues 2e and 3e to both sides and peeling off the welded parts 2d and 3d and the peripheral welded part.

By the way, in the above development processing means, the needle of the syringe is inserted into the bag through the sheet 2 or sheet 3, so the film is easily damaged and the taken X-ray image becomes unclear. Accidents were occurring frequently. In order to avoid such accidents, the handler must be extremely careful, and handling is extremely troublesome.

[Purpose of the invention]

An object of the present invention is to provide an X-ray film package that eliminates the problems of the prior art and allows easy development processing without damaging the X-ray film.

[Key points of the invention]

To achieve this objective, the present invention provides an X-ray film that
a first sheet portion that covers the entire one surface; a second sheet portion that partially covers the other surface; and a third sheet portion that covers the remainder of the other surface and the entire second sheet portion. A passage is formed using the gap between the second sheet part and the third sheet part, and the remaining part of the X-ray film in this passage is shut off from the outside by a blocking part. It is characterized by the following.

[Embodiments of the invention]

Hereinafter, the present invention will be explained based on illustrated embodiments.

FIG. 1(a) is a plan view of a dental X-ray film package according to an embodiment of the present invention, and FIG. 1(b) is a line 1 in FIG. 1(a).
Although this is a sectional view taken along the line b to rb, in order to facilitate understanding, the basic configuration of this embodiment will first be explained using FIGS. 2(a) and 2(b).

FIG. 2(a) is a plan view of the basic structure of a dental X-ray film package according to an embodiment of the present invention, and FIG. 2(b) is a plan view of the basic structure of a dental
FIG. 3 is a cross-sectional view taken along line nb-ub in a).

In the figure, 1 is an X-ray film, and 5 is a first sheet that has a slightly larger periphery than the periphery of the X-ray film 1 and covers the lower surface of the X-ray film 1. 6 is a second sheet that covers the other parts of the X-ray film 1, leaving the remainder 1a near the right end, and the upper, lower, and left periphery of the X-ray film 1 is the first sheet. It has almost the same size as the sheet 5. 7 is the second sheet 6 and the remainder 1 of the X-ray film l
This is the third sheet that covers the sheet 5, and its upper, lower, and right side edges in the figure have approximately the same thickness as the first sheet 5. However, in the drawing of the third sheet 7, the left side edge 7d is the same as the edge 5d of the first sheet 5 and the edge 6 of the second sheet 6.
slightly shorter than d. The edge 5a of the first sheet 5 and the edge 7a of the third sheet 7 are welded together, and the edges 5b, 5c of the first sheet 5 are welded together.

Edges 6b, 6c (neither edge is shown in the figure) of the second sheet 6 are welded, and
The edge 5d of the second sheet 6 and the edge 6d of the second sheet 6 are welded.

In the above configuration, the lower surface of the X-ray film l is covered with the first sheet 5, and the upper surface is covered with the second sheet 6 and the third sheet 7. The X-ray film l communicates with the outside via the second sheet 6 and the third sheet 7.

Here, the structure of a dental X-ray film according to an embodiment of the present invention will be explained based on FIGS. 1(a) and 1(b).

In the figure, the same parts as those shown in FIGS. 2(a) and 2(b) are given the same reference numerals, and the explanation thereof will be omitted. 8.9 is a first welding part and a second welding part which weld the second sheet 6 and the third sheet 7 together. The first welded portion 8 extends from near the corner of the edge 7d of the third sheet 7 to the lower edges 5c, 6c of each sheet.
, 7c, and a folding line 8b that is continuous with the inclined line 8a and is folded upward near the remaining portion 1a of the X-ray film 1 to reach the edge 7b. ing. Moreover, the second welding part 9 is
An inclined line 9a that is substantially parallel to the inclined line 8a of the first welded part 8, and a folded line 8 of the first welded part 8 that is continuous with this inclined line 9a.
It is folded downward before the folding point of b and forms the edge 7C.
It is formed as a folding line 9b that reaches . slope line 8
The second sheet 6 and the third sheet 7 are welded along the folding lines 8b, 9a and the folding lines 8b, 9b. 1
0 is a passage formed between the inclined line 8a and the inclined line 9a,
Reference numeral 11 denotes an open portion where the passage IO ends by turning back the turning line 9b.

Reference numeral 12 denotes a blocking part provided in the middle of the passage IO, and is formed by adhering the second sheet 6 and the third sheet 7 across the passage IO with an adhesive having a weak adhesive force.

As is clear from the above configuration, the first welded part 8 and the second welded part 8
By forming the welded part 9, the X-ray film l communicates with the outside only through the passage 10.
The X-ray film 1 is completely blocked from the outside by the blocking portion 12 formed at 0, and is sealed by the first sheet 5, the second sheet 6, and the third sheet 7.

Now, using an X-ray film package with such a configuration,
Development processing after line photography is performed as follows. That is, the developer is drawn into the syringe and the needle is inserted into the passageway IO as described above. At this time, the edge 7 of the third sheet 7
Since d is formed slightly shorter than the edge 6d of the second sheet 6, the entrance to the passageway IO is also clear, making insertion of the needle extremely easy. When the needle is inserted further, the blocking portion adhered with a weak adhesive is immediately peeled off, and the passageway 10 is opened. As the needle is further inserted, the tip of the needle finally passes through the passageway IO and reaches the opening 11.

During this time, the needle moves between the second sheet 6 and the third sheet 7 and does not come into contact with the X-ray film l.

Moreover, since the injection needle is inserted parallel to the second sheet 6 and the third sheet 7, there is no risk of the injection needle penetrating the second sheet 6 and damaging the X-ray film 1. When the tip of the needle reaches the opening 11, the developing solution is released, and the developer is transferred from the remaining portion 1a of the X-ray film l to the second sheet 6 and the
It enters between the line film 1 and
It penetrates into the lower surface of the line film 1, thereby performing development. Injection of fixer fluid is carried out in the same manner. Development 1
After processing, the X-ray film can be easily taken out by tearing off the third sheet 7. At this time, the third sheet 7 can be easily peeled off by inserting a finger between the third sheet 7 and the second sheet 6. Note that the needle does not necessarily need to be inserted until it reaches the opening 11, and may be inserted halfway through the passage IO, as long as the blocking part 12 is peeled off. Furthermore, since the blocking portion 12 is adhesively formed with a weak adhesive, a syringe with a rounded tip may be used instead of a needle.

As described above, in this embodiment, the first sheet covers the bottom surface of the X-ray film, the second sheet covers the remaining portion of the X-ray film other than the top surface, and the third sheet covers the second sheet and the remaining portion of the X-ray film. A narrow passage is formed between the second sheet and the third sheet by a first welding part and a second welding part consisting of an inclined line and a folded line. Since the passage was blocked with a blocking part and the X-ray film was sealed,
During the development process, it is only necessary to insert the syringe along the above-mentioned path, and there is no risk of damaging the X-ray film, and the development process can be easily performed.

Furthermore, since the X-ray film package does not use a tongue piece unlike the conventional one, it can be made small and can be easily inserted into the oral cavity.

Note that the first welded portion and the second welded portion do not necessarily need to be formed at an angle. Further, the blocking portion may be formed by welding instead of using adhesive. Further, when the blocking portion is formed by welding, it is convenient to insert the syringe if a weak welding portion is provided. Furthermore, each sheet may not be a separate sheet, but a continuous, integrated sheet may also be used.

〔Effect of the invention〕

As described above, in the present invention, the first sheet part covers one side of the X-ray film, the second sheet part covers the other side of the X-ray film, leaving only the remaining part, and the third sheet part covers one side of the X-ray film. The second sheet part and the remaining part are covered, a passage is formed in the gap between the second sheet part and the third sheet part, and the passage is blocked by the blocking part, so that the X-ray film is not damaged. Development processing can be carried out easily and without any problems, and furthermore, the X-ray film package can be made compact.
