Abstract
Description
La présente invention a pour objet une boite de protection de films photographiques contres les rayons
X.The subject of the present invention is a box for protecting photographic films against the rays.
X.
Il est est bien connu que l'exposition de pellicules photographiques ou cinématographiques aux rayons X a pour effet de voiler ceux-ç#. Or le contrôle des bagages dans les aéroports au moyen de rayons X est devenu de plus en plus systématique. Il a déjà été proposé de confectionner un sac ou une pochette de protection en utilisant une feuille de plomb insérée entre une feuille de polyéthylène et une feuille de polyester (brevet US 3.8#5.3i6). La pochette se présente sous une forme pliable dans le but de faciliter son rangement lorsqu'elle n'est pas utilisée. It is well known that exposing photographic or cinematographic film to X-rays has the effect of obscuring them. However, baggage screening at airports using X-rays has become more and more systematic. It has already been proposed to make a protective bag or pouch using a lead sheet inserted between a polyethylene sheet and a polyester sheet (US patent 3.8 # 5.3i6). The pouch is in a foldable form in order to facilitate storage when not in use.
Dans ce cas l'utilisateur doit former lui-même la pochette et la fermer au moyen d'une pince. Cette solution aboutit à une pochette sans forme définie, sans tenue et donc peu agréable à utiliser. En plus, l'utilisation répétée risque de casser les plis, sans compter les risques de perte de la pince de fermeture.In this case, the user must form the pouch himself and close it with pliers. This solution results in a pocket without defined shape, without holding and therefore not very pleasant to use. In addition, repeated use may break the folds, not to mention the risk of losing the locking pliers.
D'autre part, l'utilisation de plusieurs feuilles laminées complique la fabrication et ne permet pas de réaliser une petite boîte rigide.On the other hand, the use of several laminated sheets complicates manufacturing and does not allow a small rigid box to be produced.
Partant de cet état de la technique, et dans le but de réaliser une petite boite, susceptible de prendre place dans un sac de photo, on a tout d'abord songé à disposer une feuille de plomb entr#e deux parois de boite en matière synthétique moulée, mais la fabrication d'une telle boîte est compliquée et la boite obtenue est relativement encombrante. Starting from this state of the art, and with the aim of making a small box, capable of taking place in a photo bag, we first thought of placing a sheet of lead between two walls of the material box. molded synthetic, but the manufacture of such a box is complicated and the box obtained is relatively bulky.
La présente invention a principalement pour but de réaliser une petite boîte rigide, destinée à contenir quelques bobines de films seulement, qui ne prenne pratiquement pas davantage de place qu'une petite boite en matière plastique ordinaire obtenue en une seule opération d'injection. The main object of the present invention is to produce a small rigid box, intended to contain only a few film reels, which takes up practically no more space than a small box made of ordinary plastic material obtained in a single injection operation.
A cet effet, la boite de protection selon l'invention est caractérisée en ce qu'elle est en matière thermoplastique chargée dans la masse d'un matériau imperméable aux rayons X. To this end, the protective box according to the invention is characterized in that it is made of thermoplastic material charged in the mass with a material impermeable to X-rays.
Comme matériau imperméable aux rayons X on utilise de préférence au plomb du baryum ou un composé de baryum, le baryum ne présentant pas les dangers du plomb et étant plus facile à travailler. Il peut en particulier être facilement être réduit en poudre pour constituer une charge que l'on mélange à la matière thermoplastique à injecter. La boîte de protection peut être ainsi fabriquée par moulage en une seule opération d'injection. As an impermeable material to X-rays, barium lead or a barium compound is preferably used, since barium does not present the dangers of lead and is easier to work with. In particular, it can easily be reduced to a powder to form a filler which is mixed with the thermoplastic material to be injected. The protective box can thus be manufactured by molding in a single injection operation.
Fabriquée en prolypropylène la boite peut comporter un couvercle venu dune pièce avec la boîte et relié à celle-ci par une partie amincie formant charnière. On peut remplacer la charnière par au moins un lacet (languette) souple reliant le couvercle à la boite. bord du couvercle présente de préférence une rainure dans laquelle s'engagent les côtés de la boîte de manière à réaliser une fermeture sans solution de continuité, donc étanche aux rayons X mais en plus étanche à liteau. Made of prolypropylene, the box can have a cover from one piece with the box and connected to the latter by a thinned part forming a hinge. You can replace the hinge with at least one flexible lace connecting the cover to the box. edge of the cover preferably has a groove in which engage the sides of the box so as to produce a closure without a solution of continuity, therefore impermeable to X-rays but also impermeable to batten.
Le dessin annexé représente, à titre d'exemple, deux formes d'exécution de l'invention
La figure 1 est une vue en perspective de la boite réalisée avec une charnière reliant le corps et le couvercle.The accompanying drawing shows, by way of example, two embodiments of the invention
Figure 1 is a perspective view of the box made with a hinge connecting the body and the cover.
La figure 2 est un détail, en coupe, du bord du couvercle et d'un côté de la boîte. Figure 2 is a detail, in section, of the edge of the cover and one side of the box.
La figure 3 est une vue en coupe d'une variante d'exécution comportant une languette venue de moulage, reliant le corps et le couvercle de la boîte. Figure 3 is a sectional view of an alternative embodiment comprising a tongue coming from molding, connecting the body and the cover of the box.
La boîte 1 est de forme parallélépipèdique rectangulaire de dimension juste suffisante pour recevoir, dans cette exécution présentant à titre d'exemple, trois ou quatre bobines de films de format 24X36. Dans ce cas, la boîte est en prolypropylène chargé de baryum et elle est munie d'un couvercle 2 relié au corps de la boîte 1 par une partie amincie souple 3 formant charnière. Le couvercle 2 est muni d'un rebord vertical 4 à l'intérieur duquel et parallèlement auquel s'étend une nervure 5 sur trois côtés du couvercle et formant avec le rebord 4 une rainure verticale 6 dans laquelle viennent s'engager les extrémités amincies 7 des parois verticales de la boîte 1.Ces parties amincies présentent à leurs extrémités un bourrelet 8 qui, lors de la pénétration de la partie 7 dans la rainure 6, vient écarter élastiquement la nervure 5 pour venir se fixer à cran dans une gorge 9 prévue au fond de la rainure 6. Le rebord 4 vient approximativement en butée sur une portée 10 de la paroi 1. The box 1 is of rectangular parallelepiped shape of dimension just sufficient to receive, in this embodiment presenting by way of example, three or four reels of 24 × 36 format films. In this case, the box is made of prolypropylene loaded with barium and it is provided with a cover 2 connected to the body of the box 1 by a flexible thinned part 3 forming a hinge. The cover 2 is provided with a vertical rim 4 inside which and parallel to which extends a rib 5 on three sides of the cover and forming with the rim 4 a vertical groove 6 in which the tapered ends 7 engage. vertical walls of the box 1. These thinned parts have at their ends a bead 8 which, during the penetration of the part 7 in the groove 6, elastically spreads the rib 5 so as to be fixed to the notch in a groove 9 provided at the bottom of the groove 6. The flange 4 comes into abutment approximately on a surface 10 of the wall 1.
Selon la protection désirée, la charge de baryum représente de 5 à 40%, en volume, de la matière constituant la boîte. L'épaisseur de la paroi est de l'ordre de 1 à 3 mm. La boîte monolithique ainsi obtenue ne se distingue pas, en ce qui concerne l'usager, d'une boîte en matière plastique ordinaire. Depending on the desired protection, the barium charge represents from 5 to 40%, by volume, of the material constituting the box. The thickness of the wall is of the order of 1 to 3 mm. The monolithic box thus obtained is not distinguished, as regards the user, from a box made of ordinary plastic.
En lieu et place de baryum, il est possible d'utiliser un composé de baryum tel que du BaSO4 ou du
BaO ou tout autre matériau imperméable aux rayons X.In place of barium, it is possible to use a barium compound such as BaSO4 or
BaO or any other material impervious to X-rays.
Au lieu de prolypropylène il est possible d'utiliser d'autres matériaux thermoplastiques tels que du polystyrène ou du polyéthylène par exemple. Instead of prolypropylene it is possible to use other thermoplastic materials such as polystyrene or polyethylene for example.
De nombreuses-variantes de forme sont bien entendu possibles, avec ou sans la nervure 6 et avec des orantages différents. Many shape variants are of course possible, with or without the rib 6 and with different advantages.
Une variante d'exécution est représentée en coupe à la figure 3. Dans celle-ci le couvercle 2 est relié au corps de boîte par au moins une languette 11 venue de moulage avec le corps et le couvercle et formant un lacet. Cette languette permet de prévoir une fermeture telle que représentée à la figure 2 sur tout le pourtour du corps de boîte et du couvercle, comme indiqué en 4',5' et 8'9 de telle sorte que la protection contre les rayons X et l'étanchéité sont encore meilleures. An alternative embodiment is shown in section in Figure 3. In it the cover 2 is connected to the box body by at least one tongue 11 molded with the body and the cover and forming a lace. This tab makes it possible to provide a closure as shown in FIG. 2 over the entire periphery of the box body and of the cover, as indicated in 4 ', 5' and 8'9 so that the protection against X-rays and are even better.
