Definitions

  • 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.
  • 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.
  • 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 portable container for transporting plates intended for the manufacture of flat screens 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.
  • 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.
  • the latter are made of a self-lubricating material of polyoxymethylene acetal.
  • said cassette consists of a box and a cover provided for closing it, said cheeks being mounted inside said box.
  • the cassette thus formed can only be opened in a clean room.
  • the plates run no risk of pollution, being placed in the cassette and removed from the cassette only in a clean room.
  • 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.
  • the latter normally rests on the bottom of the case by means of at least one elastic buffer.
  • tampons are provided in the cover so that, when the cover closes the case, the cassette is wedged by said pads.
  • the plates being photosensitive, said box and the cover are advantageously made of an inactinic material, such as an inactinic poly (methyl methacrylate).
  • 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.
  • the container shown in FIG. 1 essentially comprises three elements: a case 10, a cover 20 and a cassette 30.
  • the case 10 is of substantially parallelepiped shape and is open on its face which is turned upwards when it is placed upright.
  • 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.
  • the cassette 30 is designed to be mounted and fixed inside the case 10.
  • the case 10 and the cover 20 are advantageously made of a plastic material, for example acrylonitrile butadiene styrene (ABS).
  • ABS acrylonitrile butadiene styrene
  • 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. .
  • 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.
  • spacers 33 and 34 which extend substantially perpendicular to the planes which contain the cheeks 31 and 32.
  • 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.
  • 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.
  • the cheeks 31 and 32 have for example a rectangular shape.
  • 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.
  • 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.
  • the plates to be transported can penetrate into the grooves 36 of the cheeks 31 and 32 in which they can slide.
  • 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.
  • FIG. 2 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • ABS acrylonitrile butadiene styrene
  • 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.
  • the vertical walls 13 the means for locking the cover 21 and the corresponding locking means 12 for the case 10.
  • 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.
  • the locking means 12 and 21 are provided so that, during locking, the cover 20 has a movement of approach towards the case 10.
  • the case 10 comprises, on its lower wall, four recesses 14 serving as feet for the container.
  • 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.
  • 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.
  • 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.
  • the pads 70 of the cover 20 exert a slight pressure on the plates so as to keep them in position.
  • 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.
  • 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.
  • 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.
  • spacers 91 and 92 are provided projecting above the box 90a.
  • grooved cheeks 93 and 94 are put in place which consequently adjoin the small walls of the box 90a.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
