Definitions

  • the present invention due to the collaboration of Mr. Jean, Paul THIBAULT and produced in the Services of the Applicant, relates to the packaging of photosensitive products and, more particularly, the packaging of radiographic films.
  • radiographic films As with any virgin photographic product, it is necessary to protect radiographic films from actinic radiation to which they are sensitive, before their actual exposure to an image and until their final processing so that they are not veiled, partially or completely , before their exploitation.
  • Photographic products and, in particular radiographic films must also be preserved from ambient atomospheric conditions to protect them from humidity variations: in wet atmospheres, radiographic films in packets risk adhering to each other, by their emulsified faces in contact which are then made sticky.
  • X-ray films are particularly sensitive to mechanical stresses, for example shocks or bends, which risk locally causing untimely changes in sensitivity. After exposure to an image and processing, such constraints result in artifacts, sometimes difficult to spot, which then produce parasitic images which can lead to erroneous diagnoses.
  • the packaging of the films must have its own characteristics which allow intensive, systematic use, almost on the chain.
  • Radiographic films of various formats and / or types are usually stored in this room where they are stored in film drawers or, simply, on shelves, the boots stored side by side, in an upright position.
  • the cassettes are then loaded, as required, by removing the necessary films which are extracted one by one.
  • the packaging must therefore allow a secure identification of the films it protects, authorize their storage in an upright position, the removal of the films with the minimum of opening and closing manipulation of the container. For this last intervention, it is therefore desirable that the packaging ensures, at least temporarily, from the beginning to the end of each daily service, sufficient protection so that the films are not veiled, even for the relatively frequent case, where all of the various constituent components of the container are not, all, systematically closed after each film removal.
  • the packaging of the films must have particular characteristics which allow sporadic use, on demand, piecemeal in a way.
  • the manufacturer must therefore have two types of packaging with all that this involves disadvantages for the supply of supplies, tools and equipment, storage, distribution, accounting. management, orders, catalogs in particular.
  • One of the objects of the invention is the construction of a new packaging for photosensitive products, in particular for radiographic films, which makes it possible to protect them and the ambient conditions, both actinic and hygrometric, and mechanical stresses while being relatively universal so that it can be used without distinction by any of the users.
  • the packaging for photosensitive products which are the subject of the invention consists, in particular, of a locally frangible sealed envelope to isolate the photographic products from the ambient environment and of means to protect them against mechanical attack.
  • This packaging is characterized by the fact that its envelope is provided with a manual and automatic handling device and in that with the envelope are associated identification means by marks and grouping by an arrangement.
  • the drawn embodiment of the packaging 1 according to the invention comprises an envelope 2 and protective means 5 and 9 for example.
  • radiographic films cut in format, for example fifty or one hundred films, not shown. These films are, if necessary, separated from each other by intermediate sheets or jumpers so that their two faces coated with photographic emulsion do not come into contact with each other, as is sometimes conventional in the case. However, these intermediate sheets are not essential if certain precautions are taken as to the choice of the material constituting the envelope.
  • the envelope is made of a heat-sealable plastic material, the air impermeability of which makes it possible, for example, to place it in depression with respect to atmospheric pressure so as to ensure good isolation of the radiographic films with respect to the ambient medium, in particular to remove them from the humidity variations in the air.
  • This envelope has, initially, the conformation of a tube having, if necessary, one or two longitudinal welds which is closed at its two ends by. transverse welds. At least one of these transverse welds, or the envelope in the vicinity thereof, is frangible so as to allow the opening, automatic and / or manual, of the envelope.
  • this envelope carries a coating or a filler which makes it opaque to actinic radiation liable to veil the films before use.
  • this envelope comprises a handling device which facilitates its implementation, manual or automatic, by any user.
  • radiographic films in particular for medical use, are intended for two categories of users: hospitals or clinics and doctors' offices.
  • the frequencies of use and the quantities of radiographic films exposed are notably different in these two traditional situations and, if hospitals and clinics have automatic equipment allowing the extraction of films from packaging for their use without them have to be handled by the personnel, it is not the same during the use made of it by the practitioners, or their assistants, the films being taken out manually, one by one, from the packaging to be loaded, also by hand, in a cassette.
  • the handling device with which the envelope is provided consists of a lateral bellows 3 and at least one end flap 4.
  • This bellows is formed of lateral folds, of which only those of one side are visible, intended to give ease, a certain clearance for the destacking of the films; at least one of the end flaps is intended to form, when deployed, a funnel, a sleeve for the extraction of the films and, when folded, a baffle to ensure impervious to actinic radiation.
  • the terminal flaps have a dual function; they form a funnel or sleeve and facilitate extraction and ensure sealing. This case of extraction and sealing is particularly important when manually removing the films, one by one, in the practitioner's cabin. Indeed, the room usually available to the practitioner provides only relatively poor protection of films against actinic radiation when a package has been opened and is used gradually, in particular because of the time during which it stays there after opening. , before being empty. The user must be able to plunge his hand into the envelope to grab a film and then fold the open end of the latter so that the envelope is again closed. This drawdown very often is not done because it constitutes an embarrassment, a hindrance.
  • flaps the conformation of which will be specified below, which forms a funnel or a sleeve through which one can pass, slide the hand to reach the films, flap which, as will be explained by the following, has a certain natural tendency to resume its initial configuration, which ensures - automatically, without additional operation, the light tightness although the packaging remains open.
  • At least one of the flaps is rolled up on itself or else folded in accordion or in zig-zag and ordered parallel (FIG. 3a) or perpendicularly (Figure 3b) to the edge of the stack of films.
  • the folds can be given additional elasticity.
  • elements which give them the elasticity which they lacked or which reinforces the latter.
  • glue on the flap or drown in its thickness a wire or a bar (not shown), for example metallic, which has this elastic property.
  • Another way of obtaining this result consists in depositing in the inner dihedrons of the folds a few drops or points (not shown) of an elastic substance, for example natural gum or a synthetic elastomer.
  • the packaging according to the invention must also provide protection against mechanical attack of the type that results from shocks or falls.
  • protective packaging is associated with the packaging.
  • these means are constituted by reinforcements 5 on the faces of the envelope.
  • these reinforcements consist of hollow pleats 6 which are, if necessary, reinforced by ribs 7 so as to obtain the necessary stiffness.
  • FIG. 4b it is possible, as drawn in FIG. 4b, to make folded folds 8 which are, for example, kept closed by dots of glue or solder (not shown) judiciously arranged. It is clear that these two variants can be combined.
  • These means associated with the envelope to provide protection against mechanical attack can also consist of a rigid blank, for example of cardboard of suitable texture, slipped into the envelope, between the inner wall thereof and the extreme films. from the stack. These blanks can be used alone or with reinforcements. To facilitate automatic extraction of the films from the envelope, it is preferable that these cardboard blanks are held, for example by gluing against the inner wall of the envelope so as to remain fixed to the latter when the radiographic films leave the 'envelope.
  • the packaging is not emptied automatically but where the films are removed manually one by one
  • it is preferable to practice at least that of the ends of the cardboard blanks which is close to the end of the envelope to be opened, two incisions about a few centimeters long made near and parallel to the side edges of the envelope. So when you put your hand in the envelope while deploying the funnel that constitutes the flap to take a film, the incisions allow the reinforcement blank to curve locally to contribute to the ease given by the bellows. This embodiment is not shown.
  • the means associated with the casing 2 which provide mechanical protection for its lateral and extreme edges are for example, as seen in FIG. 1, made up of a peripheral belt 9 whose width is slightly greater than the thickness an envelope filled with films and placed under vacuum before opening.
  • This belt is made, for example, of a ribbon of plastic material of appropriate rigidity and robustness or of a steel strip which encircles the envelope.
  • This belt is kept tight by welding, gluing or stapling of its ends, for example, if necessary supplemented by fixing to the envelope itself.
  • this belt is assumed to be transparent.
  • This belt allows stacking, contributes, if necessary to keep folded or rolled the flap and can wear markers.
  • this belt has a straight section in U whose parallel branches are relatively short.
  • the protection means associated with the casing 2 consist of a box 10 made of a parallelepipedic case 11, the two opposite end sections of which are open to form a sheath , and in which can slide a drawer 12 made of a bottom of which two opposite ends (of which only one is shown) are folded in U.
  • the envelope is deposited in the drawer, the two U folded over it and the whole slid in the case.
  • the package has been drawn partially open, in the configuration which it occupies after manual removal of a film.
  • the folds of the extremal flap are closed on themselves and form a baffle which prevents the infiltration of light by the open end between the opening and the funnel which remains ajar. This / more, protected by the U of the drawer which partially covers it, even if the drawer is not pushed back completely into the case and the U reintroduced into the latter.
  • the packaging is drawn flat but it is clear that the latter can rest on edge, on one or the other of its slices.
  • means associated with the envelope are used to identify and group.
  • the identification is, for example, obtained by physically detectable markers which indicate in clear and / or code the film format, their type, the brand, the expiration date ...
  • markers are, at least for some of them readable by eye or by optical, magnetic, etc. sensors
  • Such references 13 are drawn in FIG. 2 only.
  • This grouping arrangement for constituting units can take several forms, some of which are shown in the drawings in FIG. 5.
  • this arrangement consists of a strip 14 on which are periodically distributed packages which are attached to it for example by glue dots. This strip is then folded to form a Greek for example. There are batches of five packages for example which form a grouping unit and these packages are held together by a strap 15 or else by dots of adhesive placed between them and judiciously distributed.
  • a sheath 16 made of a heat-shrinkable material into which packages of strings have been inserted After conformation in Greek of the filled sheath, the packages of a batch are grouped into a unit by means of a strap 15 or with dots of glue as indicated with reference to FIG. 5a.
  • the packaging according to the invention while ensuring the protection of the radiographic films, is of almost universal use since '' it makes it possible to satisfy the very distinct needs of the two categories of users with a single configuration.
  • the packaging according to the invention has a significant additional advantage in its variant embodiment drawn in Figure 2 in particular.
  • This advantage which conventional throat boxes do not have consists in the space saving obtained during the storage of the components of the packaging before their film filling.
  • protective means made of a box it is clear that the sheath-shaped case 11 can be deformed in parallelogram and laid flat. Similarly, the drawer can be deployed, its ends flattened in line with the bottom.
