Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a dental X-ray film packaging body for packaging an X-ray film to prevent exposure to the X-ray film during dental X-ray photography. .

[Conventional technology]

When taking X-ray pictures of teeth, an X-ray film that is wrapped in an opaque material is used in order to prevent the X-ray film from being exposed to light. This packaged X-ray film is placed in the patient's mouth and
Radiography is performed. Such an X-ray film package will be explained with reference to the drawings.

Figure 3 is a plan view of a conventional X-ray film package.
FIG. 4 is a sectional view taken along the line - in FIG. 3.
In each figure, 1 and 2 indicate sheets made of opaque synthetic resin, and 3, 4, and 5 indicate three sides of each sheet 1 and 2. The three sides 3, 4, and 5 of each sheet are welded together to form a flat bag. 6 is the opening side of this bag. The X-ray film F is inserted into the bag through the opening on the opening side 6. Reference numeral 7 indicates an adhesive for adhesively sealing the opening sides 6 of the sheets 1 and 2. 8 is a tongue piece at the tip of the sheet 1, and 9 is a tongue piece at the tip of the sheet 2. The tongue pieces 8 and 9 constitute a peeling part. The bag is sealed on all four sides, so
There is no risk of external light entering the bag, and the X-ray film F is not exposed. This dental X-ray film packaging can therefore be handled in the presence of light.

During X-ray photography, this dental X-ray film package is placed in the patient's oral cavity, and X-rays are irradiated through the affected area. The X-rays that have passed through the affected area reach the X-ray film F through the sheet 1 or 2, whereby an X-ray image of the affected area is obtained on the X-ray film F.
The X-ray film F is developed and fixed by injecting a developer and a fixer into the bag of the dental X-ray film package taken out from the oral cavity using a syringe.
Finally, by pulling the tongues 8 and 9 on both sides, the welds on the sides 3 and 4 are peeled off, and the X-ray film F is taken out. FIG. 5 is a sectional view of another conventional dental X-ray film package. In the figure, F is a dental X-ray film, and 11 is a sheet made of an opaque synthetic resin that has approximately the same width as the dental X-ray film F and a length shorter than the length of the dental X-ray film F. . 12 is dental X-ray film F in width and length.
It is a sheet made of opaque synthetic resin that is almost the same as that of . Layer sheet 11 and sheet 12, and
By welding the sides to each other, a bag with a large opening on one side is constructed. Dental X-ray film F is inserted into this bag. 13 is a lid made of opaque synthetic resin that completely covers the exposed portion 14 of the dental X-ray film F that is exposed from the sheet 11 when the dental X-ray film F is inserted into the bag; It is welded to the corresponding sides of 11 and 12. 1
5 is a sealing part that seals the sheet 11 and the lid 13; 16;
is a tongue piece at the tip of the lid 13.

This dental X-ray film package is also subjected to X-ray photography, development processing, and removal of the dental X-ray film F in the same manner as shown in FIGS. 3 and 4.

[Problem that the invention attempts to solve]

By the way, in the conventional dental X-ray film package shown in FIGS. 3 and 4, only the portion bonded with the adhesive 7 and the tongue pieces 8 and 9 are longer than the length of the X-ray film F. . Since the dental X-ray film package is inserted into the oral cavity as described above to take pictures, the smaller the size, the easier it is for the patient to insert, and the larger the size, the more pain and discomfort it will cause. However, the above-mentioned conventional dental X-ray film packaging body is
The size of the oral cavity is considerably larger than that of the conventional oral cavity, which increases pain and discomfort for the patient and makes it difficult to insert it into the oral cavity.

Furthermore, the conventional dental X-ray film packaging body shown in FIG.
The shape and dimensions are almost the same, and the above problem is solved. However, since the tongue piece 16 is present on the surface, when the dental X-ray film package is inserted into the oral cavity, the tongue piece comes into contact with the tongue and gums, causing pain and discomfort. If the sheet gets caught on something, there is a risk that the sheet will peel off.
When taking out the dental X-ray film F from the bag after the development process, the lid 13 has to be peeled off and then the dental X-ray film must be taken out from the bag, which is troublesome.

The purpose of the present invention is to solve the above-mentioned problems of the prior art, reduce the overall size, make the surface smooth, and furthermore,
To provide a dental X-ray film package that allows easy removal of the X-ray film.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes an opaque sheet having approximately the same shape and dimensions as dental X-ray film, and a bag body facing this sheet. Peel off the other opaque sheet, the folded sheet that is provided continuously with the other sheet and is folded back near the edge of one sheet and inserted into the bag, and the one sheet and the folded sheet. and a sealing part to which the sealing part is adhered, leaving only a part of the sealing part.

[Effect]

A bag is made by welding the three sides of one sheet and the other sheet to each other, and a folded sheet that is continuously formed on the other sheet is inserted into the bag, and one sheet and the folded sheet are connected as appropriate. Seal the bag by gluing it in place.

〔Example〕

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

FIG. 1 is a plan view of a dental X-ray film package according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line - shown in FIG. 1. In each figure, numeral 21 is an opaque, thin, flexible synthetic resin sheet, which has approximately the same shape and size as the dental X-ray film F. 22 is sheet 21
It is also an opaque, thin and flexible synthetic resin sheet, and has almost the same shape and size as the sheet 21, and is formed integrally with the sheet 21. 23, 2
4 and 25 indicate the three sides of the sheets 21 and 22, the sheets 21 and 22 are folded at the side 25, and the side sides 23 and 2 are folded.
At step 4, they are adhered to each other by welding or the like to form a flat bag. The interior of this bag is large enough to allow the dental X-ray film F to be inserted almost snugly into the bag. A folded sheet 26 is provided continuously and integrally with the sheet 22, and like the sheets 21 and 22, it is made of an opaque, thin, and flexible synthetic resin. This folded sheet 26 is folded back at a portion 26a that substantially opposes the edge 21a of the sheet 21, and is finally inserted into a flat bag. In this state, the inner surface of the sheet 21 and the outer surface of the folded sheet 26 are in contact with each other.

27 is an adhesive for bonding the sheet 21 and the folded sheet 26;
6 are adhered without any gaps in the width direction to prevent light rays from entering the bag. This adhesive 2
The position 7 is selected to be an appropriate distance L from the tip 21a of the sheet 21. 21b indicates a peeling portion corresponding to the distance L in the sheet 21.

Next, an example of manufacturing this dental X-ray film will be described. A long, narrow sheet is punched out of an opaque, thin, flexible synthetic resin, and the sheet has a side of 25 mm.
and folded at portion 26a, sheets 21, 2
2. A folded sheet 26 is formed. Adhesive 27 is applied over the entire width of the predetermined fixed location of the folded sheet 26.
is applied, and the dental X-ray film F is sandwiched between the folded sheets 21, 22 and the folded sheet 26 as shown in FIG. By pressing the sheet 21, the sheet 21 and the folded sheet 26 are bonded together with the adhesive 27. Next, the sides 23 and 24 are welded over their entire length, and the sheets 21 and 22 are welded together in some parts, and the sheet 21, the folded sheet 26, and the sheet 22 are welded in other parts. This seals the dental X-ray film F.

This kind of dental X-ray film packaging can not only reduce the overall size to the necessary minimum size, but also has a smooth surface that does not expose the sheet edge (tongue), making it suitable for X-ray photography. Sometimes, when inserted into the oral cavity, there is less pain or discomfort, and the insertion is easier. In addition, there are fewer snags during handling. When the X-ray imaging is finished and the development processing is completed, put your finger in the gap between the edge 21a of the sheet 21 and the folded sheet 26, hold the peeling part 21b, and peel off the welding of the side pieces 23 and 24 while removing the sheet 21. Peel it off and take out the dental X-ray film F. In this case, the dental X-ray film F is exposed simply by peeling off the sheet 21, so as in the conventional example shown in FIG. There is no need for the troublesome effort of extracting the.

In addition, in the description of the above embodiment, the sheets 21, 2
2 and the folded sheet 26 are formed as a single sheet, but the present invention is not limited to this, and separate sheets may also be used. Further, instead of bonding with the adhesive 27, welding can also be used.

〔Effect of the invention〕

As described above, in the present invention, a bag is made up of two sheets that have almost the same shape and dimensions as dental X-ray film, and a folded sheet that is continuous with one sheet is inserted into the bag and adhered. Since the other sheet is provided with a peel-off part, the entire sheet can be formed to the minimum size, and the surface can be smooth without any sticking parts. When inserting into the oral cavity,
It can relieve pain and discomfort. moreover,
The dental X-ray film package is also less likely to get caught during handling. Furthermore, the dental X-ray film can be easily taken out after the development process.
