Abstract

The container consists of a frame (1) with horizontal tie bars (2) at the top and bottom and standing on legs. The frame contains the sides of the container proper which fits the frame so that the sides of the container do not protrude beyond the sides of the frame. The side of the container are bowed to the same curvature on each face. The bottom of the container is fitted with an outlet pipe (7) or flange for the discharge of the product. The top of the framework is fitted with angles to ease stacking.

Description

La présente invention est relative aux conteneurs et, plus particulièrement, à ceux formés d'un récipient de forme générale parallélépipédique rectangle porté par un cadre, notamment par un cadre-palette, de marnière à ce que les faces latérales du récipient ne dépassent pas du parallélépipède droit défini par le cadre. The present invention relates to containers and, more particularly, to those formed by a container of generally rectangular parallelepiped shape carried by a frame, in particular by a pallet frame, so that the lateral faces of the container do not protrude from the right parallelepiped defined by the frame.

On connait déjà de tels conteneurs, qui offrent l'avantage de simplifier la manutention des produits liquides ou en vrac, d'utiliser le mieux possible l'espace des entrepôts, camion ou wagons grâce à la possibilité de les empiler et de bien protéger les produits des intempéries. Nais ils présentent l'incon vénient d'être coûteux et de ne pas pouvoir résister aux pressions sous lesquelles certains produits doivent être conservés ou vidangés. We already know of such containers, which offer the advantage of simplifying the handling of liquid or bulk products, of making the best possible use of warehouse space, trucks or wagons thanks to the possibility of stacking them and well protecting the weather products. However, they have the disadvantage of being expensive and of not being able to resist the pressures under which certain products must be stored or drained.

L'invention pallie ces inconvénients par un contenu qui conserve les qualités des conteneurs antérieurs, mais qui est bien moins coûteux et bien moins lourd, tout en étant plus résistant mécaniquement au point de résister à des pressions élevées. The invention overcomes these drawbacks by a content which retains the qualities of the previous containers, but which is much less expensive and much less heavy, while being more mechanically resistant to the point of withstanding high pressures.

Suivant l'invention, les faces latérales et, de préférence, les six faces du récipient sont bombées en tournant leur convexité vers l'exterieur.  According to the invention, the lateral faces and, preferably, the six faces of the container are curved by turning their convexity towards the outside.

On a constate que cette courbure régulière et irréversible et notamment quand le rapport de la flèche à la corde soustendant l'arc suivant lequel une face est bombée est compris entre 0,03 et 0,1 environ, de manière à obtenir une courbure nettement plus importante que celle résultant de la simple déformation élastique d'un récipient au remplissage, et qui va au-delà de la limite élastique, confère au récipient une résistance mécanique surprenante, même lorsque l'épaisseur de la paroi n'est plus que les 2/3 de celle d'un récipient classique. On gagne en poids, on gagne en métal. On gagne aussi en résistance mécanique avec possibilité de stocker ou de vidanger sous pression. It has been observed that this regular and irreversible curvature and in particular when the ratio of the arrow to the string underlying the arc according to which a face is curved is between 0.03 and 0.1 approximately, so as to obtain a curvature clearly more important than that resulting from the simple elastic deformation of a container during filling, and which goes beyond the elastic limit, gives the container a surprising mechanical resistance, even when the thickness of the wall is only 2 / 3 of that of a conventional container. We gain in weight, we gain in metal. It also gains in mechanical resistance with the possibility of storing or emptying under pressure.

On a constaté, d'autre part, que si les contraintes de travail du métal de chaque face du conteneur sont égales, le conteneur répond à un optimum pression et épaisseur, c'est pourquoi les faces du récipient sont bombées vers I'extérieur, maisen conservant au rapport flèche-corde sous-tendant l'arc de l'une quelconque des 5 ou 6 faces une valeur identique se situant entre 0,03 et 0,1 quelles que soient les dimensions de chacune des faces. It has been noted, on the other hand, that if the metal working constraints on each face of the container are equal, the container responds to an optimum pressure and thickness, this is why the faces of the container are curved outwards, but keeping the arrow-chord ratio underlying the arc of any one of the 5 or 6 faces an identical value between 0.03 and 0.1 whatever the dimensions of each of the faces.

De préférence, la section d'une face par un plan parallèle à un côte de cette face est un arc de cercle.  Preferably, the section of a face by a plane parallel to a side of this face is an arc of a circle.

la figure 1 est une vue en élévation d'un récipient suivant l'invention
la figure 2 est une vue en plan
la figure 3 est une vue en élévation d'une variante;
et les figures 4 et 5 illustrent deux autres variantes.
In the accompanying drawing, given only by way of example
Figure 1 is an elevational view of a container according to the invention
Figure 2 is a plan view
Figure 3 is an elevational view of a variant;
and Figures 4 and 5 illustrate two other variants.

Le conteneur des figures 1 et 2 comprend un cadre porteur constitue de quatre montants 1 entretoisés en haut et en bas par des entretoises 2, les entretoises inférieures permettant à un chariot élévateur de soulever l'ensemble. The container of Figures 1 and 2 comprises a support frame consists of four uprights 1 braced at the top and bottom by spacers 2, the lower spacers allowing a forklift to lift the assembly.

Un récipient en acier ou acier inox, ou alliage aluminium de 2 mm d'épaisseur, de forme générale parallélipipédique est soudé au cadre par les arêtes. Toutes les faces du récipient 3 sont bombées en tournant leur convexité vers 1'extérieur. Le rapport de la flèche à la corde sous-tendant les arcs suivant lesquels les faces sont bombées est compris entre 0,03 et 0,1. La section d'une face par un plan parallèle aux côtés de cette face est un arc de cercle. A container made of steel or stainless steel, or aluminum alloy 2 mm thick, of generally parallelepiped shape is welded to the frame by the edges. All the faces of the container 3 are curved by turning their convexity towards the outside. The ratio of the arrow to the string underlying the arcs according to which the faces are curved is between 0.03 and 0.1. The section of a face by a plane parallel to the sides of this face is an arc of a circle.

Dans la face supérieure est ménagé un trou d'homme 4 ou ouverture, muni d'un couvercle 5. In the upper face is provided a manhole 4 or opening, provided with a cover 5.

De la face inférieure fait saillie une poche 6 de vidange dont part un conduit 7 de vidange avec vanne 8. From the underside projects a drain pocket 6 from which a drain pipe 7 with valve 8 starts.

Les montants 1 sont évidés en 9 vers le haut avant de s'relargir en coins 10 de centrage. The uprights 1 are hollowed out at 9 upwards before widening into corners 10 for centering.

Ce conteneur peut résister à une pression pouvant 2 atteindre 10kg/cm suivant ltépaisseur située dans les normes définies ci-dessus et le rapport flèche corde. This container can withstand a pressure of up to 10 kg / cm 2 depending on the thickness located in the standards defined above and the rope deflection ratio.

A la figure 3, une trémie 11 de distribution de forte épaisseur, par rapport à celle du conteneur 3, prolonge ce dernier vers le bas. La trémie 11, qui n'a pas la courbure requise, doit être épaisse, alors que le conteneur 3 lui-même peut avoir une épaisseur ne représentant que les deux tiers de celle de la trémie, tout en résistant aussi bien. In FIG. 3, a very thick distribution hopper 11, relative to that of the container 3, extends the latter downwards. The hopper 11, which does not have the required curvature, must be thick, while the container 3 itself can have a thickness representing only two thirds of that of the hopper, while being resistant as well.

Les figures 4 et 5 illustrent deux autres configurations de soudage du conteneur 3 au cadre 4, l'une (figure 4) à angles 2 cassés, l'autre (figure 5) à angles 12 vifs, tandis qu'à la figure 2, on voit que les angles 12 sont arrondis.  FIGS. 4 and 5 illustrate two other configurations for welding the container 3 to the frame 4, one (FIG. 4) with broken angles 2, the other (FIG. 5) with sharp angles 12, while in FIG. 2, we see that the angles 12 are rounded.
