PACKAGE OF SENSITIZED MATERIAL FOR X-RAY PURPOSES.
Application filed December This invention relates to packages of sensitized material for X-ray purposes and more particularly to packages containing a considerable number of sheets of such material as furnished and shipped by the manufacturer.
In practice, it is necessary for the X-ray operator to protect such packages carefully from the effects of X-rays, as by storing them in special metal cabinets or at a very considerable distance from the X-ray' machine. Some operators do not fully realize the necessary extent of such precautions and inadvertently permit the packages to remain where they become fogged. Such films, even if the fog is but partial, yieldpoor images and the operator, not realizing that he is at fault, attributes this to poor materials. The manufacturer, having no means of proving the contrary, gets the blame and may in addition replace the goods.
The object of the present invention is to provide a package of such sensitive goods which will, in case of such accidental exposure, cause to be imprinted on the sensitive material a distinguishing image quite distinct from any that Would result in the regular use of the material. This and other objects are accomplished by the use of a package for shipment and storage only, made of cardboard or other material opaque to light but pervious to X-rays having a. strip or piece of heavy metal foil opposite the image bearing portions of the sensitive material. X-rays an image of the design of this foil will be imprinted on the material. This will protect the manufacturer from unjust demands and warn the operator that his technique is faulty.
Reference will now be made to the accompanying drawing wherein the same reference characters indicate the same parts throughout.
Fig. 1 shows the container with the two portions thereof separated, one element being partly broken away.
Fig. 2 is a longitudinal section of a package including the container shown in Fig. 1.
Fig. 3 is a perspective View of an opened package of another form.
Fig. 4 is a perspective view of another form of container.
package in open condition.
If the package is then exposed to 23, 1926'. Serial No. 156,724.
The cover 2 fits over the tube and forms with the casing 4 a smooth light tight package. At a point, here shown as within the casing 4, a. band 5 of lead foil or ofother material impervious to X-rays is applied around the rectangular tube 3 so as to completely en circle the same, The sensitive material, such as the usual glass plates or cut film sheets are placed within the container. practice, one or two dozen plates or films of a size to fit the container will be placed in each package, though a smaller number is shown for the sake of clearness. In general there Will be alternate sensitized sheets (3 and spacing papers 7. I
In applying the term tubular .to the part 3, I use the word in its correct gcometv size. A band of metal foil or equivalent material encircles the tube 13.
It is not necessary that the impervious material completely surround the package, 'though I consider this preferable. If desired, the foil may be in the form of a trademark, design or warning word. In Fig. 4 is shown a form embodying a box member 24 having the upwardly extending inner flange 23, about which fits the cover member 22 hinged to the box member at 21. On the bottom of the box and the upper surface of the cover-are placed pieces 25 of lead foil or equivalent material in the form of a warning word.
In Fig. 5, a stack of cut films 36 is shown as packed in an envelope 34 around which passes a band 35 of metal foil or equivalent material. The envelope has on one end a closure tab 32.
till
The foil may or may not be visible to the user. In the form shown in Fig. 1, it is at all times invisible; in Fig. 3 it is visible when the box is open and in Fig. 4 it is on theoutsideof the package.
In general the packages are opened and such plate holders or Cassettes filled as may be needed, the unused sensitized sheets being leftin the orignal container which should be light tight when closed. The containers and the filled cassettes usually remain in the dark room where the loading takes place until used.
. It is to benoticed that in order for this indication to be of use, it must be on a part of the package that is not used during the exposure of the film so that the appearance of the warning image on the developed film will necesarily indicate that the package as a whole was exposed to rays independently of the purposeful exposure of the individual It is-further to be noted that I preferably place the impervious material in a position I the large area occupying all the middle part of the film.
In order to produce such an image, moreover, the design must cover the area of the sensitive sheet only partially. If it completely covers it, the entire material will, of course, be protected, but this will make an expensive package and the operator will not be warned, so that plates in otherpackages or loaded cassettes which are not pro: ,tected and which may be in the same exposed location, may be fogged.
While I preferably use lead or tin foil, other material such as a coating'of rubber with particles of. heavy metal or salts of heavy metal incorporated therein may be used. a
It is obvious'that numerous other embodi- .I claim as new and desire to secure by Letters Patent:
1. An article of manufacture comprising a light tight container of opaque material pervious to X-rays, sensitized sheet material within said container, and material impervious to X-rays on each side of said sheet material and opposite a part only of the medial portion of said sheet material.
2. An article of manufacture and commerce comprising .a container of material pervious to X-rays and impervious to light,
and including a movable cover, sensitized material in sheet form within said cont-amer,
and metal foil impervious to X-rays car:
ried by the container on both sides of the sensitive material and on each side 0 posite a part only of the medial portion of t e sensitized material.
3. As an article of manufacture a box for the shipment and storage of sensitized sheet material for X-rays purposes and com-- prising a movable cover whereby the box f may be opened without destruction and may be closed to render the box again light tight,
said bo'x being made of opaque material pervious to- X-rays, a band of material impervious to sheet film sufiicient for a plurality of X-raiyl's exposures within the box and opposite t band of material.
4;. An article of manufacture and commerce comprising a light tight flat container having u per and lower parallel walls per-' vious to -rays, a stack of flat sensitized sheets within said container and between and parallel to the walls, the container in cluding a movable cover portion whereby the container may be opened without de-. struction for the removal of the plates, a strip of metal foil impervious to X-rays X-rays encircling the box and and extending across the medial portion of each of said walls, whereby upon the package to tions of the sensitized sheets.
