Description
Compte-gouttes à réservoir.
La présente invention concerne un comptegouttes à réservoir qui permet d'assurer la distribution des gouttes par simple pression sur une membrane élastique.
Il est construit, de préférence, de façon que, pour chaque nouvelle goutte à obtenir, il faut donner une nouvelle pression sur la membrane; de ce fait, la distribution se fait avec précision. Le dessin ci-annexé montre, à titre d'exemple seulement, une forme d'exécution du compte-gouttes à réservoir suivant l'invention.
La fig. 1 en est une coupe longitudinale et
la fig. 2 en est une vue en bout.
La tête B est filetée intérieurement à l'une de ses extrémités pour se visser sur le corps C; l'autre extrémité se termine par une fine saillie conique G, percée selon son axe d'un trou capillaire. Un bouchon A, percé d'un trou borgne conique, comporte en son centre une aiguille H d'un diamètre correspondant au trou capillaire pour pouvoir s'y introduire, le capuchon se posera sur la saillie conique G de la tête B et les cônes rendront le réservoir absolument étanche, l'aiguille H pénétrant dans le trou capillaire l'empêchera de s'obstruer. Le corps C est tubulaire, il est fileté à ses extrémités pour recevoir, d'une part, le pied D avec sa membrane élastique
E en matière plastique inaltérable et, d'autre part, la tête B. Les faces extrêmes du corps C sont coniques pour garantir l'étanchéité de la membrane E et de la tête D.
Le pied D, taraudé et percé, reçoit la membrane E, qui repose sur un épaulement conique F. Le pied D, en bloquant la membrane E sur le corps C, rend l'ensemble parfaitement étanche.
REVENDICATION:
Compte-gouttes à réservoir, caractérisé en ce qu'il est formé de pièces assemblées de façon étanche et démontable et en ce qu'il comprend un corps tubulaire fileté à ses deux extrémités, sur l'une desquelles est vissée une tête munie d'une saillie conique percée axialement d'un trou capillaire et sur l'autre desquelles est vissé un pied maintenant une

Dropper with reservoir.
The present invention relates to a dropper with reservoir which makes it possible to ensure the distribution of the drops by simple pressure on an elastic membrane.
It is preferably constructed in such a way that, for each new drop to be obtained, a new pressure must be given on the membrane; therefore, the distribution is done with precision. The accompanying drawing shows, by way of example only, one embodiment of the dropper with reservoir according to the invention.
Fig. 1 is a longitudinal section and
fig. 2 is an end view.
The head B is internally threaded at one of its ends to screw onto the body C; the other end ends with a fine conical projection G, pierced along its axis with a capillary hole. A plug A, pierced with a conical blind hole, has in its center a needle H with a diameter corresponding to the capillary hole in order to be able to be introduced there, the cap will rest on the conical projection G of the head B and the cones will make the reservoir absolutely waterproof, the H needle entering the capillary hole will prevent it from becoming blocked. The body C is tubular, it is threaded at its ends to receive, on the one hand, the foot D with its elastic membrane
E in unalterable plastic material and, on the other hand, the head B. The end faces of the body C are conical to guarantee the tightness of the membrane E and of the head D.
The foot D, tapped and drilled, receives the membrane E, which rests on a conical shoulder F. The foot D, by blocking the membrane E on the body C, makes the assembly perfectly waterproof.
CLAIM:
Dropper with reservoir, characterized in that it is formed of parts assembled in a sealed and removable manner and in that it comprises a tubular body threaded at its two ends, on one of which is screwed a head provided with a conical projection pierced axially with a capillary hole and on the other of which is screwed a foot holding a
