Abstract

PURPOSE:To print a discrimination pattern for specifying the object to be photographed at the same time on a film by attaching an X-ray nontransmitting grid plate to a visible light nontransmitting plastic sack. CONSTITUTION:A sack 2 for containing an X-ray film 1 is made of a sheet prepared by kneading PVC with a visible light nontransmitting material and disclosure tongues 6 are formed in an optional shape on the side to be disclosed. A grid plate 4 made of an X-ray nontransmitting material having a grid scale and a discrimination mark formed in one body by etching or the like is overlaid on one side of the sack 2 and stuck with a 2-liquid type epoxy adhesive, and further, the plate 4 is covered with a transparent or semitransparent protective film 5 made of PVC, polyester, polyolefin, or the like type. The grid plate 4 may be attached by inserting it into another sack similar in shape to the sack 2 formed in addition.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package for storing an X-ray film used in dental X-ray photography.

Conventionally, when a tooth or the like is to be photographed by X-rays, a package containing an X-ray photographic film is brought into contact with the back side of the tooth, and X-rays are irradiated from the outside.

Thereafter, the film inside the package is developed and subjected to observation. In addition, in order to observe the location and spread of the affected area of the tooth, measurements were taken by applying a scale directly onto the film after development.

However, when observing magnified images using a projector, etc., it is impossible to measure by directly applying a scale to the image on the display because the magnification of the projector is not constant, and the correlation between the magnifications must be considered. There was the complication of having to perform measurements. For this reason, if a thick lattice scale pattern is formed on the surface of the bag used to package the X-ray film using X-ray opaque ink containing lead, by screen printing or other methods, the film will not be visible during X-ray imaging. A method was developed in which a grid-like scale pattern was printed onto the surface.

However, with this method, it is difficult to form a lattice scale with a lattice width of 200μ or less, so a scale with a thick lattice line width is inevitably formed. The disadvantage was that the image was obscured by the wide scale.

In addition, the identification pattern used to identify the person being photographed has the same drawbacks, and furthermore, a package structure in which a small piece with an identification symbol is attached to the corner of the surface of the package instead of printing means is not suitable for storage. n stuck from the surface during handling.
Accidents of small pieces falling off often occurred.

The present invention eliminates these various drawbacks, and also provides an identification pattern for specifying the object to be photographed at the same time.
- This is a new packaging body for storing X-ray photographic film that can be printed with a number printed on it. This is a package for storing X-ray photographic film with a scale, characterized in that it is equipped with a Gliso IJ plate made of material *1.

Hereinafter, the present invention will be explained according to an embodiment shown in the drawings.

1 and 2 are a sectional view and a plan view of a package according to the present invention. Reference numeral 1 denotes an X-ray photographic film, and 2 a bag for storing the film, which is made of vinyl chloride and mixed with a coloring material that is opaque to visible light. Moreover, an opening tongue piece 0 of an optional cane is formed on the opening side of the bag body 2.

The method of storing the X-ray film 1 in the bag body 2 is as follows.
The film can be placed between two synthetic resin sheets, and the peripheral edge of the film corresponding to the peripheral edge of the film can be thermally bonded or pierced with a known adhesive. In addition, even if the film is enclosed in a bag with a three-way round H attached, the I
stomach. Furthermore, in the case of production in Tokyo, the bag can be formed from a continuous double film.

Apply 20 to 5011 parts of a two-component epoxy thread adhesive on one side of the bag body 2 thus formed to form adhesive)-3,
On the adhesive layer 3, a glyph 1 made of an X-ray opaque material 1 on which a grid pattern and an identification symbol are integrally formed by etching are bonded together, and the plates 4 are bonded together. A transparent or translucent protective film 5 made of vinyl chloride, polyester, polyolefin, etc. is formed on top of the protective film 5 (see FIG. 3). In this case, the grid plate 4 covering the protective film 5 is prepared in advance, and when bonding to the bag body,
” 2. Can be applied and bonded with adhesive. Covering the grid plate 4 with the protective film 5 prevents the grid plate 4 from being exposed to the grid holes 8.1 and the adhesive 4, and also prevents the grid plate 4 with sharp edges from being directly exposed to the outside, making it safe to handle. Furthermore, it is convenient to handle the package if the protective film for at least the identification mark portion is made transparent or semi-transparent.

In addition, the above-mentioned glyph 1 plate 4 should be attached only in cases where it is connected twice. There is no need to provide a storage section 10 of approximately the same shape as the bag body 2, and the storage section 10 can be stored there.

In FIG. 2, reference numeral 5 indicates a grid plate 5 made of an X-ray opaque material that is attached to the bag body of the present invention, and has a thickness of approximately 50 to 300 mm.
After degreasing the stainless steel plate II, planographic offsetting 1
, screen printing, octopus printing, rubber letterpress printing, etc. [After forming the Esotin braces I-III for forming grid-like scales and identification symbol patterns by any means, the width of the grid portion 7 is made using an Esothynda liquid such as ferric chloride. The lattice holes 8 are etched so as to have a diameter of 20 to 100 μm, the lattice holes 8 are in the form of a 500 to I 50 (l II) grid, and the identification symbol 9 is etched so as to be integrated with the lattice portion 7.

J for the present invention, then lattice i? Since the width of ++ 7 can be formed to 200 p or less, it does not affect the image of teeth etc. taken on the film after X-ray photography, does not create confusing shadows, and can be easily distinguished from the lattice part 7. Since the symbol 9 is formed integrally, it is not only economically superior, but also
Accidents in which individuals cannot be identified due to the conventional identification symbol attached to the package falling off can be completely prevented.

Moreover, the bag can be easily opened by simply pulling the opening tongue to take out the film after X-ray photography, and the grid plate does not damage the film surface.

By the way, the grid plate used in the present invention is not limited to the stainless steel plate shown in the embodiments, but may be any material such as a copper plate or a lead plate that is opaque to X-rays and has excellent etching properties. Furthermore, the etching resist film can also be formed by a photosensitive method instead of the various printing methods described above. In this case, it is possible to produce a wide variety of grid plates with different identification symbols by separately preparing the grid-like scale pattern original and the identification symbol pattern original and changing the identification symbol pattern original when forming the etching resist 1Iit%. Furthermore, a metal plate with a narrow grid portion can be formed by a punching method instead of an etching method. In the case of the punching method, unlike the etching method, there is no need to form a resist film, and it can be formed in one culm.
