It consists of a container (1) which rests on an elastic system (30) containing a liquid (29). The displacement of this liquid (29) occurs inside a gauge (31) in proportion to the weight of the substance introduced into the container (1). The device according to the invention is in particular intended for isothermal bottles and for pharmaceutical containers.

Description

La pressente invention concerne un dispositif permettant de connaître, à tout moment, le niveau d'une substance notamment alimentaire mais non exclusivement, contenue dans un récipient opaque ou légèrement opaque. The present invention relates to a device making it possible to know, at any time, the level of a substance, in particular a food substance, but not exclusively, contained in an opaque or slightly opaque container.

Actuellement la seule technique existante, pour vérifier le niveau d'un produit dans un tel récipient, est basée sur le principe des vases communiquants, principe appliqué par exemple aux cuves à vin. Currently the only existing technique, to check the level of a product in such a container, is based on the principle of communicating vases, principle applied for example to wine tanks.

Ce système est limité uniquement aux fluides, de surcroît ne craignant pas des échanges d'ordre thermiques, lumineuses ou autres avec le milieu extérieur. This system is limited only to fluids, moreover not afraid of thermal, light or other exchanges with the outside environment.

Le dispositif selon l'invention permet de généraliser la méthode de vérification du niveau à toute substance, quelque soit son état physique : pour connaître le niveau du contenu de façon précise, l'invention consiste à rendre, le récipient qui contient la substance , mobile par rapport à un autre récipient qui le renferme. Un système élastique permet de peser le récipient contenant la substance. Le système de pesage peut être adapté à toute substance quelque soit sa nature. La visualisation du niveau de la substance peut se faire
- soit par une lecture directe sur le récipient pour un mouvement ample,
- soit par une lecture indirecte pour un mouvement moindre.The device according to the invention makes it possible to generalize the method of checking the level to any substance, whatever its physical state: in order to know the level of the content in a precise manner, the invention consists in making the container which contains the substance mobile. compared to another container which contains it. An elastic system allows the container containing the substance to be weighed. The weighing system can be adapted to any substance whatever its nature. The visualization of the level of the substance can be done
- either by direct reading on the container for a wide movement,
- either by indirect reading for less movement.

Un système hydraulique (le récipient contant la substance plonge dans un liquide indicateur de niveau ou appuie sur une cavité élastique contenant un liquide qui indique le niveau par l'intermédiaire d'une jauge) ou un système mécanique, basé sur le principe du bras de levier, amplifient ce mouvement. A hydraulic system (the container containing the substance plunges into a liquid indicating level or presses on an elastic cavity containing a liquid which indicates the level by means of a gauge) or a mechanical system, based on the principle of the arm of lever, amplify this movement.

Le récipient (1) qui reçoit la substance, repose sur un système élastique formé de la pièce (30) et (25) dans le cas de la figure 1 ou des pièces (23) (24) et (25) dans le cas de la figure 2 ou (8) (10) (11) et (15) dans le cas de la figure 3. Un système (14) permet d'étalonner le système élastique afin d'adopter l'invention à toute substance quelque soit sa densité. With reference to these drawings, the device comprises a container (1) movable relative to the housing (7). The container (1) which receives the substance, rests on an elastic system formed by the part (30) and (25) in the case of FIG. 1 or by the parts (23) (24) and (25) in the case of Figure 2 or (8) (10) (11) and (15) in the case of Figure 3. A system (14) allows to calibrate the elastic system in order to adopt the invention to any substance whatever its density.

L'indicateur du niveau de la substance introduite dans le récipient (1) est observable entre le couvercle (4) solidaire du récipient (1) et le boîtier (7). The indicator of the level of the substance introduced into the container (1) is observable between the cover (4) integral with the container (1) and the housing (7).

Si cette indication est insuffisamment perceptible; différents systèmes permettent d'amplifier cette indication du niveau de la substance. If this indication is insufficiently perceptible; different systems make it possible to amplify this indication of the level of the substance.

- Dans la forme de réalisation selon la figure 1, le récipient (1) repose sur la cavité élastique (30) qui renferme le liquide indicateur (29), celui-ci se déplace proportionnellement au poids de la substance introduite dans le récipient (1). Le déplacement de ce liquide (29) se fait à l'intérieur d'une jauge (31),
- dans la forme de réalisation selon la figure 2, le boîtier (7) contient un liquide (29), qui lors du déplacement du récipient (1) par rapport au boîtier (7) se déplace proportionnellement au poids de la substance introduite dans le récipient (1). Le déplacement de ce liquide (29) est observable grâce à une fenêtre (22) réalisée dans le boîtier (7)
- dans la forme de réalisation selon la figure 3, le récipient (i) repose sur la pièce (8) articulée en (9).La pièce (8) entraîne la rotation du bras de levier (15) autour de l'articulation (16) solidaire de la pièce (12) elle-même solidaire du boîtier (7). D'un côté de l'articulation (16) on trouve le système élastique indiqué plus haut, de l'autre côté de cette articulation (16) on trouve l'index (21) relié au bras de levier (15) par une série de pièces articulées (20), (19), (18), (17). L'index (21) est observable grâce à une fenêtre (22) réalisée dans le récipient (7) (coupe A-A).- In the embodiment according to FIG. 1, the container (1) rests on the elastic cavity (30) which contains the indicator liquid (29), this moves in proportion to the weight of the substance introduced into the container (1 ). The displacement of this liquid (29) takes place inside a gauge (31),
- in the embodiment according to Figure 2, the housing (7) contains a liquid (29), which during movement of the container (1) relative to the housing (7) moves in proportion to the weight of the substance introduced into the container (1). The movement of this liquid (29) can be observed through a window (22) made in the housing (7)
- In the embodiment according to FIG. 3, the container (i) rests on the part (8) articulated at (9). The part (8) causes the lever arm (15) to rotate around the joint ( 16) secured to the part (12) itself secured to the housing (7). On one side of the joint (16) we find the elastic system indicated above, on the other side of this joint (16) we find the index finger (21) connected to the lever arm (15) by a series articulated parts (20), (19), (18), (17). The index (21) can be seen through a window (22) made in the container (7) (section AA).

La pièce (13) peut éventuellement supporter l'ensemble du mécanisme. Un autre système élastique (5), placé entre le couvercle (4) et le boîtier (7), peut éventuellement seconder le système élastique (10) si la substance le nécessite. Ce même système élastique (5) peut jouer le rôle d'un joint d'étanchéité au même titre que les membranes (6) et (28).The part (13) can possibly support the entire mechanism. Another elastic system (5), placed between the cover (4) and the housing (7), can possibly assist the elastic system (10) if the substance requires it. This same elastic system (5) can play the role of a seal in the same way as the membranes (6) and (28).

Afin de réduire le mouvement du récipient (1) à une simple translation et le limiter dans sa course par rapport au boîtier (7), il est prévu sur le couvercle (4) une ou plusieurs butées qui se logent dans une ou plusieurs rainures réalisées dans le boîtier (7) (coupe B-B). Le bouchon (3) permet de fermer le récipient (1). Le bouchon (2) permet de bloquer le mouvement de translation du récipient (1) par rapport au boîtier (7) par vissage de l'ensemble. In order to reduce the movement of the container (1) to a simple translation and limit it in its stroke relative to the housing (7), there are provided on the cover (4) one or more stops which are housed in one or more grooves made in the housing (7) (section BB). The cap (3) allows the container (1) to be closed. The plug (2) blocks the translational movement of the container (1) relative to the housing (7) by screwing the assembly.
