Description

La présente invention concerne un container portable destiné au transport de plaques de matériaux fragiles, et plus particulièrement de plaques de verre ou de quartz minces, notamment de plaques destinées à la fabrication d'écrans plats.The present invention relates to a portable container intended for the transport of plates of fragile materials, and more particularly of glass or thin quartz plates, in particular of plates intended for the manufacture of flat screens.

Des plaques destinées à la fabrication d'écrans plats sont traitées en salles blanches et sont transportées, pour d'autres traitements, vers d'autres salles blanches. Les salles blanches en question peuvent être distantes et il est alors nécessaire de prévoir le transport des plaques d'une salle à l'autre. Il existe donc un besoin pour un container destiné à ce transport qui doit se faire dans des conditions de protection contre les chocs et contre les poussières et ou l'humidité de l'environnement.Plates intended for the manufacture of flat screens are treated in clean rooms and are transported, for other treatments, to other clean rooms. The clean rooms in question can be distant and it is then necessary to plan the transport of the plates from one room to another. There is therefore a need for a container intended for this transport which must be done in conditions of protection against shocks and against dust and or humidity of the environment.

Les plaques de verre traitées pour la fabrication d'écrans plats sont fragiles et peuvent ainsi casser sous l'action d'un choc, mais elles sont aussi photosensibles. Par ailleurs, elles ne peuvent être manipulées qu'en salle blanche. Il en est de même de leurs supports qui pourraient les contaminer. Il est donc nécessaire de prendre des mesures pour tenir compte de ces différents facteurs.The glass plates treated for the manufacture of flat screens are fragile and can thus break under the action of a shock, but they are also photosensitive. Furthermore, they can only be handled in a clean room. The same is true of their supports which could contaminate them. It is therefore necessary to take measures to take account of these different factors.

Le but de l'invention est donc de proposer un container qui réponde au besoin mentionné ci-dessus et qui présente les caractéristiques souhaitées ci-dessus.The object of the invention is therefore to propose a container which meets the need mentioned above and which has the characteristics desired above.

A cet effet, un container portable pour le transport de plaques destinées à la fabrication d'écrans plats selon l'invention est caractérisé en ce qu'il comprend un étui logeant une cassette et pouvant être fermé par un couvercle, ladite cassette étant pourvue de deux joues planes parallèles entre elles dont les faces en regard l'une de l'autre sont respectivement pourvues de rainures parallèles entre elles et se correspondant deux à deux d'une joue à l'autre de manière à pouvoir recevoir à coulissement lesdites plaques, lesdites joues étant maintenues à distance aux moyens d'entretoises.To this end, a portable container for transporting plates intended for the manufacture of flat screens according to the invention is characterized in that it comprises a case housing a cassette and which can be closed by a cover, said cassette being provided with two flat cheeks parallel to each other, the faces opposite one another are respectively provided with grooves parallel to each other and corresponding two by two from one cheek to the other so as to be able to receive said plates slidingly, said cheeks being kept at a distance by means of spacers.

Afin de faciliter l'enclenchement des plaques dans les rainures, notamment lorsque celles-ci sont fines, lesdites rainures ont une section trapézoïdale et, avantageusement, elles comportent, dans leur partie supérieure, une entrée qui est élargie sensiblement en forme de tronc de pyramide renversé.In order to facilitate the engagement of the plates in the grooves, in particular when the latter are fine, said grooves have a trapezoidal section and, advantageously, they comprise, in their upper part, an entry which is widened substantially in the form of a truncated pyramid reversed.

Afin d'éviter que les plaques de verre n'altèrent les rainures des joues, ces dernières sont constituées dans un matériau autolubrifiant d'acétal polyoxyméthylène.In order to prevent the glass plates from altering the grooves of the cheeks, the latter are made of a self-lubricating material of polyoxymethylene acetal.

Selon une autre caractéristique de l'invention, ladite cassette est constituée d'une boîte et d'un couvercle prévu pour la fermer, lesdites joues étant montées à l'intérieur de ladite boîte.According to another characteristic of the invention, said cassette consists of a box and a cover provided for closing it, said cheeks being mounted inside said box.

Alors que l'étui pourrait être ouvert en dehors des salles blanches, notamment aux douanes et par exemple par inadvertance, la cassette ainsi constituée ne peut être ouverte qu'en salle blanche. Il en résulte que les plaques ne courent aucun risque de pollution, étant mises en place dans la cassette et retirées de la cassette qu'en salle blanche.While the case could be opened outside clean rooms, especially at customs and for example inadvertently, the cassette thus formed can only be opened in a clean room. As a result, the plates run no risk of pollution, being placed in the cassette and removed from the cassette only in a clean room.

Afin de faciliter le nettoyage de la cassette et notamment des joues de la cassette, on a prévu que les joues soient amovibles.In order to facilitate cleaning of the cassette and in particular of the cheeks of the cassette, provision has been made for the cheeks to be removable.

A cette fin, ladite cassette est pourvue d'entretoises fixées sur les grandes parois de la boîte, lesdites entretoises étant prévues pour permettre la mise en place desdites joues par coulissement entre leurs extrémités et les petites parois de la boîte.To this end, said cassette is provided with spacers fixed on the large walls of the box, said spacers being provided to allow the establishment of said cheeks by sliding between their ends and the small walls of the box.

Pour éviter la transmission des chocs subis par l'étui à la cassette, celle-ci repose normalement sur le fond de l'étui par l'intermédiaire d'au moins un tampon élastique. De même, des tampons sont prévus dans le couvercle de manière que, lorsque le couvercle ferme l'étui, la cassette soit calée par lesdits tampons.To avoid transmission of the shocks suffered by the case to the cassette, the latter normally rests on the bottom of the case by means of at least one elastic buffer. Likewise, tampons are provided in the cover so that, when the cover closes the case, the cassette is wedged by said pads.

Les plaques étant photosensibles, ladite boîte et le couvercle sont avantageusement constitués dans un matériau inactinique, tel qu'un poly(méthacrylate de méthyle) inactinique.The plates being photosensitive, said box and the cover are advantageously made of an inactinic material, such as an inactinic poly (methyl methacrylate).

Selon une autre caractéristique de l'invention, le fond de ladite cassette est pourvu de tampons élastiques sur lesquels reposent les plaques mises en place dans lesdites joues et des tampons sont prévus pour exercer une force d'appui sur lesdites plaques mises en place lorsque le couvercle ferme l'étui ou lorsque la cassette est fermée par le couvercle.According to another characteristic of the invention, the bottom of said cassette is provided with elastic buffers on which the plates placed in said cheeks rest and buffers are provided to exert a pressing force on said plates put in place when the cover closes the case or when the cassette is closed by the cover.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
  • Fig. 1 is a perspective view of the three elements which make up a container according to the invention in a first embodiment,
  • Fig. 2 is a perspective view of two grooves of a cheek of a cassette of a container according to the invention,
  • Fig. 3 is a sectional view along the plane III / III of FIG. 2 of a groove according to the invention,

  • Fig. 7 is a top view of an open cassette 30 according to the second embodiment of the invention.

Le container représenté à la Fig. 1 comprend essentiellement trois éléments: un étui 10, un couvercle 20 et une cassette 30.The container shown in FIG. 1 essentially comprises three elements: a case 10, a cover 20 and a cassette 30.

L'étui 10 est de forme sensiblement parallélépipèdique et est ouvert sur sa face qui se trouve tournée vers le haut lorsqu'il est posé debout. Des bords de l'ouverture 11, en saillie au-dessus de la face supérieure de l'étui 10, partent des parois verticales 13 dont les fonctions seront explicitées ci-après.The case 10 is of substantially parallelepiped shape and is open on its face which is turned upwards when it is placed upright. The edges of the opening 11, projecting above the upper face of the case 10, leave the vertical walls 13 whose functions will be explained below.

Le couvercle 20 est prévu de manière à pouvoir fermer l'ouverture 11 de l'étui 10. Il comporte des moyens de verrouillage 21 qui coopèrent avec des moyens correspondants 12 montés sur l'étui 10 et qui assurent un verrouillage du couvercle 20 sur l'étui 10.The cover 20 is provided so as to be able to close the opening 11 of the case 10. It includes locking means 21 which cooperate with corresponding means 12 mounted on the case 10 and which lock the cover 20 on the case 10.

Enfin, la cassette 30 est prévue pour être montée et fixée à l'intérieur de l'étui 10.Finally, the cassette 30 is designed to be mounted and fixed inside the case 10.

L'étui 10 et le couvercle 20 sont avantageusement constitués en une matière plastique, par exemple de l'acrylonitrile butadiène styrène (ABS). Ainsi, ils sont transparents aux rayons X ce qui permet de pouvoir connaître le contenu de l'étui 10 sans devoir l'ouvrir, ce qui ne serait pas le cas s'ils étaient constitués en un matériau opaque à ces rayons, tel qu'un matériau métallique. Par conséquent, l'étui 10 peut rester fermé lors de contrôles de son contenu, notamment dans des aéroports, ce qui évite toute entrée de poussières dans l'étui 10 et de mise en contact de celles-ci avec les plaques transportées à ces moments.The case 10 and the cover 20 are advantageously made of a plastic material, for example acrylonitrile butadiene styrene (ABS). Thus, they are transparent to X-rays which makes it possible to be able to know the content of the case 10 without having to open it, which would not be the case if they were made of a material opaque to these rays, such as a metallic material. Consequently, the case 10 can remain closed during checks of its content, in particular in airports, which avoids any entry of dust into the case 10 and of bringing these into contact with the plates transported at these times. .

La cassette 30 du premier mode de réalisation est constituée de deux joues planes 31 et 32 parallèles entre elles et reliées ensemble par des entretoises 33 et 34 qui s'étendent sensiblement perpendiculairement aux plans qui contiennent les joues 31 et 32. Lorsque les joues 31 et 32 sont placées verticalement telles que représentées, deux entretoises 33 relient ensemble respectivement les coins supérieurs correspondants des joues 31 et 32 alors que deux autres entretoises 34 relient ensemble des points correspondants des joues 31 et 32 qui sont situés à un niveau intermédiaire. Quant aux parties inférieures des joues 31 et 32, elles sont reliées entre elles par une embase 35 sur laquelle repose la cassette 30 lorsqu'elle est posée debout.The cassette 30 of the first embodiment consists of two flat cheeks 31 and 32 parallel to each other and connected together by spacers 33 and 34 which extend substantially perpendicular to the planes which contain the cheeks 31 and 32. When the cheeks 31 and 32 are placed vertically as shown, two spacers 33 respectively connect together the corresponding upper corners of the cheeks 31 and 32 while two other spacers 34 connect together corresponding points of the cheeks 31 and 32 which are located at an intermediate level. As for the lower parts of the cheeks 31 and 32, they are connected together by a base 35 on which the cassette 30 rests when it is placed upright.

Les joues 31 et 32 ont par exemple une forme rectangulaire.The cheeks 31 and 32 have for example a rectangular shape.

Les dimensions des éléments de la cassette 30, notamment les longueurs des entretoises 33 et 34 et de l'embase 35 et les largeur et hauteur des joues 31 et 32, sont telles que la cassette 30 peut être logée à l'intérieur de l'étui 10, l'embase 35 reposant alors et étant fixée, par exemple au moyen de vis (une seule 40 est visible), sur le fond de l'étui 10. La partie supérieure de chaque joue 31, 32 est également fixée, par exemple au moyen de vis (deux vis 51 et 52 d'un même côté de l'étui 10 sont visibles), sur les parois 13 de l'étui 10.The dimensions of the elements of the cassette 30, in particular the lengths of the spacers 33 and 34 and of the base 35 and the width and height of the cheeks 31 and 32, are such that the cassette 30 can be housed inside the case 10, the base 35 then resting and being fixed, for example by means of screws (only one 40 is visible), on the bottom of the case 10. The upper part of each cheek 31, 32 is also fixed, for example by means of screws (two screws 51 and 52 on the same side of the case 10 are visible), on the walls 13 of the case 10.

Les faces 31a et 32a des joues 31 et 32 de la cassette 30 qui se trouvent en regard l'une de l'autre sont respectivement pourvues de rainures 36 qui sont parallèles entre elles et qui se correspondent deux à deux d'une joue à l'autre. Ces rainures 36 sont verticales lorsque la cassette 30 est debout sur son embase 35.The faces 31a and 32a of the cheeks 31 and 32 of the cassette 30 which lie opposite one another are respectively provided with grooves 36 which are parallel to each other and which correspond two by two from one cheek to the 'other. These grooves 36 are vertical when the cassette 30 is standing on its base 35.

Les plaques à transporter peuvent pénétrer dans les rainures 36 des joues 31 et 32 dans lesquelles elles peuvent coulisser.The plates to be transported can penetrate into the grooves 36 of the cheeks 31 and 32 in which they can slide.

Le matériau qui constitue les joues 31 et 32 est autolubrifiant, afin d'éviter que les plaques de verre à transporter n'altèrent les rainures 36 et réciproquement. Ce matériau est par exemple une matière plastique d'acétal polyoxyméthylène.The material which constitutes the cheeks 31 and 32 is self-lubricating, in order to prevent the glass plates to be transported from damaging the grooves 36 and vice versa. This material is for example a plastic material of polyoxymethylene acetal.

On a représenté à la Fig. 2 les parties supérieures de deux rainures 36 et leurs entrées 36e et, à la Fig. 3, une section d'une rainure 36.There is shown in FIG. 2 the upper parts of two grooves 36 and their inlets 36e and, in FIG. 3, a section of a groove 36.

Comme on peut le constater sur la Fig. 3, les rainures 36 ont une section trapézoïdale. L'avantage d'une telle mesure réside dans le fait qu'une plaque à transporter qui entre dans une rainure 36 ne se trouve en contact avec celle-ci que selon une ligne, ou un point et non selon un plan, ce qui serait le cas si elle présentait une section rectangulaire. On diminue ainsi les frottements des plaques avec les rainures 36.As can be seen in FIG. 3, the grooves 36 have a trapezoidal section. The advantage of such a measure lies in the fact that a plate to be transported which enters a groove 36 is in contact with it only along a line, or a point and not according to a plane, which would be the case if it had a rectangular section. This reduces the friction of the plates with the grooves 36.

Afin de faciliter l'introduction des plaques à transporter dans les rainures 36, on a ménagé, dans la partie supérieure de chacune d'elles (Fig. 2), une entrée 36e qui, partant de la rainure 36, s'élargit vers le haut. Chaque entrée 36e présente, par exemple, une forme sensiblement de tronc de pyramide renversé. Chaque entrée 36e a par exemple une section au droit des bords supérieurs des joues 31 ou 32 qui est rectangulaire.In order to facilitate the introduction of the plates to be transported into the grooves 36, an opening 36e has been formed in the upper part of each of them (FIG. 2) which, starting from the groove 36, widens towards the high. Each entry 36e has, for example, a shape substantially of an inverted pyramid trunk. Each entry 36e has for example a section to the right of the upper edges of the cheeks 31 or 32 which is rectangular.

Dans le mode de réalisation représenté à la Fig. 1, l'étui 10 est constitué de deux demi-coquilles 10a et 10b qui comportent, chacune, un flanc sensiblement rectangulaire et qui sont assemblées, par exemple par collage, par les arêtes 10c de leurs rebords. Afin d'assurer une bonne étanchéité du joint de collage des deux demi-coquilles, une languette (non représentée) peut être prévue, à l'intérieur de l'étui 10, superposant le joint de collage entre les deux demi-coquilles 10a et 10b. Chaque demi-coquille 10a, 10b est par exemple thermoformée en une matière résistante, telle que de l'acrylonitrile butadiène styrène (ABS).In the embodiment shown in FIG. 1, the case 10 consists of two half-shells 10a and 10b which each have a substantially rectangular flank and which are assembled, for example by gluing, by the edges 10c of their edges. To to ensure good sealing of the bonding joint of the two half-shells, a tongue (not shown) may be provided, inside the case 10, superimposing the bonding joint between the two half-shells 10a and 10b . Each half-shell 10a, 10b is for example thermoformed in a resistant material, such as acrylonitrile butadiene styrene (ABS).

On a représenté à la Fig. 4 une coupe de l'étui 10 avec le couvercle 20 le chapeautant et la cassette 30 réalisée selon le premier mode et fixée à l'intérieur de l'étui 10. On voit également sur cette Fig. 4 les parois verticales 13, les moyens de verrouillage du couvercle 21 et les moyens de verrouillage correspondants 12 de l'étui 10.There is shown in FIG. 4 is a section through the case 10 with the cover 20 covering it and the cassette 30 produced according to the first mode and fixed inside the case 10. We also see in this FIG. 4 the vertical walls 13, the means for locking the cover 21 and the corresponding locking means 12 for the case 10.

Le couvercle 20 est formé par une première coquille 22 dont la section est en forme de U avec une largeur prévue pour qu'elle puisse s'adapter sur les parois verticales 13 de l'étui 10. Une seconde coquille 23 de dimensions supérieures vient coiffer la première coquille 22 et est assemblée avec elle, par exemple, par collage. Elle forme un rebord 22a qui est prévu pour se trouver parallèle mais distant du rebord correspondant 11a de la face supérieure de l'étui 10 lorsque le couvercle 20 le coiffe. Un joint d'étanchéité 60 est fixé sur le rebord 11a de l'étui 10. Lorsque le couvercle 20 coiffe l'étui 10 et qu'il est verrouillé par les moyens 12 et 21, le joint 60 est légèrement écrasé entre les rebords 11a et 22a, assurant ainsi une bonne étanchéité.The cover 20 is formed by a first shell 22, the cross section of which is U-shaped with a width provided so that it can be adapted to the vertical walls 13 of the case 10. A second shell 23 of larger dimensions covers the first shell 22 and is assembled with it, for example, by gluing. It forms a rim 22a which is intended to be parallel but distant from the corresponding rim 11a of the upper face of the case 10 when the cover 20 covers it. A seal 60 is fixed to the edge 11a of the case 10. When the cover 20 covers the case 10 and it is locked by the means 12 and 21, the seal 60 is slightly crushed between the edges 11a and 22a, thus ensuring a good seal.

Les moyens de verrouillage 12 et 21 sont prévus pour que, lors du verrouillage, le couvercle 20 ait un mouvement de rapprochement vers l'étui 10.The locking means 12 and 21 are provided so that, during locking, the cover 20 has a movement of approach towards the case 10.

L'étui 10 comporte, sur sa paroi inférieure, quatre renfoncements 14 servant de pieds au container.The case 10 comprises, on its lower wall, four recesses 14 serving as feet for the container.

On notera que la seconde coquille 23 du couvercle 20 (Fig. 1) présente un renfoncement transversal 24 destiné à recevoir une poignée 25 qui, au repos, ne dépasse pas le niveau supérieur du couvercle 20.It will be noted that the second shell 23 of the cover 20 (FIG. 1) has a transverse recess 24 intended to receive a handle 25 which, at rest, does not exceed the upper level of the cover 20.

Des tampons 70 sont prévus dans le fond du couvercle 20 sur la paroi de la coquille 22, par exemple l'un d'un côté et l'autre de l'autre. De même, des tampons 80 reposent sur l'embase 35 de la cassette 30, l'un au voisinage d'une joue 31 et l'autre au voisinage de l'autre joue 32 de la cassette 30.Buffers 70 are provided in the bottom of the cover 20 on the wall of the shell 22, for example one on one side and the other on the other. Similarly, buffers 80 rest on the base 35 of the cassette 30, one in the vicinity of a cheek 31 and the other in the vicinity of the other cheek 32 of the cassette 30.

Pour monter des plaques dans le container de l'invention, on introduit les plaques à transporter dans les rainures 36 des joues 31 et 32 dans lesquelles on les fait coulisser jusqu'à ce qu'elles reposent sur les tampons 80 de la cassette 30. Lorsqu'on referme l'étui 10 au moyen du couvercle 20, les tampons 70 du couvercle 20 exercent une légère pression sur les plaques de manière à les maintenir en position.To mount plates in the container of the invention, the plates to be transported are introduced into the grooves 36 of the cheeks 31 and 32 in which they are made to slide until they rest on the pads 80 of the cassette 30. When the case 10 is closed by means of the cover 20, the pads 70 of the cover 20 exert a slight pressure on the plates so as to keep them in position.

La Fig. 5 montre un autre de mode de réalisation de l'invention dans lequel l'étui 10 et son couvercle 20 ont sensiblement les mêmes structures que celles qui ont été décrites en relation avec la Fig. 1, seule diffère la structure de la cassette 90.Fig. 5 shows another embodiment of the invention in which the case 10 and its cover 20 have substantially the same structures as those which have been described in relation to FIG. 1, only the structure of cassette 90 differs.

Celle-ci est essentiellement constituée d'une boîte 90a pourvue d'un couvercle 90b. La cassette 90 est sensiblement parallélépipédique. Elle est décrite en détail en relation avec les Figs. 6 et 7 qui la montrent, d'une part, mise en place dans l'étui 10 et, d'autre part, vue de dessus.This essentially consists of a box 90a provided with a cover 90b. The cassette 90 is substantially parallelepiped. It is described in detail in relation to Figs. 6 and 7 which show it, on the one hand, placed in the case 10 and, on the other hand, seen from above.

Sur la Fig. 6, on voit l'étui 10 et le couvercle 20, les systèmes d'attache 12, 21, les pieds 14 et le joint 60. La boîte 90a est montrée fermée par son couvercle 90b.In Fig. 6, we can see the case 10 and the cover 20, the fastening systems 12, 21, the feet 14 and the seal 60. The box 90a is shown closed by its cover 90b.

A l'intérieur de la boîte 90a, le long de ses bords longitudinaux supérieurs, on a prévu des entretoises 91 et 92 en saillie au-dessus de la boîte 90a. Chaque entretoise 91, 92 fixée par exemple par collage, a sa longueur telle que des espaces soient formés entre ses extrémités et les surfaces internes des petites parois de la boîte 90a (voir les espaces e à la Fig. 7). Par coulissement vertical et par insertion dans lesdits espaces e, sont mises en place des joues rainurées 93 et 94 qui jouxtent par conséquent les petites parois de la boîte 90a.Inside the box 90a, along its upper longitudinal edges, spacers 91 and 92 are provided projecting above the box 90a. Each spacer 91, 92 fixed for example by gluing, has its length such that spaces are formed between its ends and the internal surfaces of the small walls of the box 90a (see the spaces e in FIG. 7). By vertical sliding and by insertion into said spaces e , grooved cheeks 93 and 94 are put in place which consequently adjoin the small walls of the box 90a.

Les joues 93 et 94 comportent des rainures qui sont parallèles entre elles et qui se correspondent deux à deux d'une joue 93 et à l'autre joue 94 de manière à pouvoir recevoir à coulissement vertical des plaques de verre. Les rainures sur les joues 93 et 94 présentent les mêmes structures que les rainures des joues 31 et 32 du premier mode de réalisation, et notamment la forme des rainures 36 montrées aux Figs. 2 et 3.The cheeks 93 and 94 have grooves which are parallel to each other and which correspond two by two to one cheek 93 and to the other cheek 94 so as to be able to receive vertically sliding plates of glass. The grooves on the cheeks 93 and 94 have the same structures as the grooves on the cheeks 31 and 32 of the first embodiment, and in particular the shape of the grooves 36 shown in Figs. 2 and 3.

On notera que les parties des joues 91 et 92 en saillie au-dessus de la boîte 90a permettent également le guidage du couvercle 90b lors de sa pose sur la boîte 90a.It will be noted that the parts of the cheeks 91 and 92 projecting above the box 90a also allow the cover 90b to be guided when it is placed on the box 90a.

Le fait que les joues 93 et 94 puissent être extraites de la boîte 90a permet de faciliter les opérations de leur nettoyage. En effet, lorsqu'elles sont montées dans la boîte 90a, leurs parties inférieures sont difficilement accessibles. Ainsi, si elles étaient fixes dans la boîte 90a, ces parties inférieures seraient difficiles à nettoyer ce qui n'est pas le cas si les joues sont démontables.The fact that the cheeks 93 and 94 can be extracted from the box 90a makes it possible to facilitate the operations of their cleaning. Indeed, when they are mounted in the box 90a, their lower parts are difficult to access. Thus, if they were fixed in the box 90a, these lower parts would be difficult to clean which is not the case if the cheeks are removable.

La cassette 90 est fermée par un adhésif 96 qui fait le tour du joint entre la boîte 90a et son couvercle 90b. Cet adhésif assure l'étanchéité de la cassette 30.The cassette 90 is closed by an adhesive 96 which circles the joint between the box 90a and its cover 90b. This adhesive seals the cassette 30.

Elle est ensuite placée à l'intérieur de l'étui 10 de manière à reposer sur un tampon 100 prévu dans le fond de l'étui 10 et être calée entre deux tampons 101 et 102 prévus sur les faces internes des parois 13 de l'étui 10.It is then placed inside the case 10 so as to rest on a pad 100 provided in the bottom of the case 10 and be wedged between two pads 101 and 102 provided on the internal faces of the walls 13 of the case 10.

Le fond de la boîte 90a est pourvu de tampons élastiques 103 sur lesquels reposent les plaques de verre lorsqu'elles sont mises en place dans la boîte 90a. De même, des tampons 104 sont prévus dans le fond du couvercle 90b. Ces tampons 104, lorsque le couvercle 90b ferme la boîte 90a contenant des plaques, exerce une force d'appui sur les plaques ce qui a pour effet de les maintenir en place, malgré les chocs que peut subir l'étui 10.The bottom of the box 90a is provided with elastic pads 103 on which the glass plates rest when they are placed in the box 90a. Similarly, buffers 104 are provided in the bottom of the cover 90b. These buffers 104, when the cover 90b closes the box 90a containing plates, exerts a pressing force on the plates which has the effect of keeping them in place, despite the shocks that the case 10 can undergo.

La boîte 90a et son couvercle 90b sont constitués dans un matériau inactinique tel qu'un poly(méthacrylate de méthyle) rendu inactinique par ajout de charges appropriées. Il pourrait en être de même des entretoises 91 et 92 ainsi que des joues rainurées 93 et 94.The box 90a and its cover 90b are made of an inactinic material such as a poly (methyl methacrylate) rendered inactinic by adding appropriate fillers. It could be the same for spacers 91 and 92 as well as grooved cheeks 93 and 94.
