Abstract
L'INVENTION A TRAIT A UN FLACON ESSOREUR MUNI D'UNE TUBULURE D'ASPIRATION AMOVIBLE. CETTE TUBULURE EST CONSTITUEE DE DEUX PARTIES TUBULAIRES 4, 6 VISSEES L'UNE DANS L'AUTRE. L'UNE D'ELLES 4 EST ENFONCEE DE L'INTERIEUR PAR UNE OUVERTURE CORRESPONDANTE 3 DANS LE FLACON ESSOREUR 1 DE MANIERE A VENIR REPOSER, PAR UN EPAULEMENT 5, CONTRE LE COTE INTERIEUR DU FLACON ESSOREUR, ET L'AUTRE PARTIE TUBULAIRE 6, QUI PORTE L'OLIVE, EST VISSEE DE L'EXTERIEUR A CETTE PREMIERE PARTIE. CE FLACON ESSOREUR, CONVENABLEMENT EQUIPE, EST UTILISABLE POUR DES FILTRATIONS ASSISTEES PAR UNE ASPIRATION.THE INVENTION RELATES TO A WRAPPING FLASK EQUIPPED WITH A REMOVABLE SUCTION TUBING. THIS TUBING IS CONSISTING OF TWO TUBULAR PARTS 4, 6 SCREWED INTO ONE ANOTHER. ONE OF THEM 4 IS PRESSED FROM THE INSIDE THROUGH A CORRESPONDING OPENING 3 INTO THE WRAPPING BOTTLE 1 SO AS TO COME TO REFIT, BY A SHOULDER 5, AGAINST THE INSIDE SIDE OF THE WASHER BOTTLE, AND THE OTHER TUBULAR PART 6, WHICH WEARS THE OLIVE, IS SCREWED FROM THE EXTERIOR TO THIS FIRST PART. THIS WRAPPING BOTTLE, PROPERLY EQUIPPED, CAN BE USED FOR FILTRATIONS ASSISTED BY SUCTION.
Description
L'invention concerne un flacon essoreur muniThe invention relates to a squeeze bottle provided
d'une tubulure d'aspiration d'un genre nouveau. suction tubing of a new kind.
Le flacon essoreur est utilisé en association avec des appareils de filtration. Il est constitué d'un récipient à fond plat et il comporte, à son extrémité supé- rieure, un col dans lequel vient se placer, avec liaison étanche aux gaz,l'appareil de filtration. Le col a une ouverture latérale, laquelle est reliée par un tuyau à une The wiper bottle is used in combination with filtration devices. It consists of a flat-bottomed container and has at its upper end a neck in which the filtration apparatus is placed with a gastight connection. The neck has a lateral opening, which is connected by a pipe to a
pompe à vide.vacuum pump.

ture celle-ci porte une pièce tubulaire en verre, fixée par fusion, qui est évasée vers l'extérieur en forme de cône et dans laquelle le tuyau est enfoncé. L'inconvénient de ce mode de construction est que le tuyau n'est maintenu que par la dépression régnant dans le flacon: il doit être tenu à la main lorsqu'on fait le vide dans le flacon, et il The latter carries a melt-bonded tubular glass piece which is conically flared outward and into which the pipe is recessed. The disadvantage of this method of construction is that the pipe is maintained only by the depression in the bottle: it must be held by hand when the bottle is emptied, and it

Dans un troisième mode de construction l'olive est amovible, elle est en verre ou en matière plastique et In a third mode of construction the olive is removable, it is made of glass or plastic and
elle est éventuellement munie d'une rondelle d'étanchéité. it is optionally provided with a sealing washer.
L'olive est enfoncée dans l'ouverture du flacon essoreur (brevet de la R. F.A. N0 1.161.059). L'inconvénient de ce mode de construction est la grande précision qui est imposée à la forme de l'ouverture. Si cette condition n'est pas remplie la jonction ne tient pas le vide et/ou l'olive tombe. Dans The olive is pressed into the opening of the squeeze bottle (R.F. Patent No. 1,161,059). The disadvantage of this mode of construction is the great precision that is imposed on the shape of the opening. If this condition is not fulfilled the junction does not hold emptiness and / or the olive falls. In

rieur dans l'ouverture et elle est maintenue de l'extérieur par un écrouchapeau. Ce mode de réalisation a plusieurs inconvénients: l'olive, à laquelle il faut bien donner une certaine longueur, ne peut pas être enfoncée de l'intérieur lorsque le flacon essoreur est de petite taille et a un col étroit, et dans ce cas elle est donc in the opening and is held from the outside by a nutcap. This embodiment has several disadvantages: the olive, which must be given a certain length, can not be pressed from the inside when the wiper bottle is small and has a narrow neck, and in this case it is therefore
inutilisable; le diamètre intérieur de l'olive est relati- unusable; the inside diameter of the olive is relatively
vement petit, ce qui limite la puissance d'aspiration. small, which limits the suction power.
Il fallait donc trouver -- et c'était là le but du présent inventeur - un flacon essoreur ayant une ouverture reliée par un tuyau de raccordement à la pompe à vide, flacon qui n'ait pas les inconvénients,exposés ci-dessus, des modes It was therefore necessary to find - and this was the purpose of the present inventor - a wiper bottle having an opening connected by a connecting pipe to the vacuum pump, bottle which does not have the disadvantages, set out above, modes
de construction connus.known construction.
Ce problème technique est résolu par la présente invention, qui a pour objet un flacon essoreur à tubulure d'aspiration amovible, caractérisé en ce que cette tubulure d'aspiration est constituée de deux parties tubulaires - vissables l'une dans l'autre dont l'une est enfoncée dans une ouverture correspondante ménagée dans le flacon essoreur, cela de telle façon qu'elle soit appliquée par un épaulement contre le côté intérieur du flacon essoreur, et l'autre, qui porte l'olive, est vissée de l'extérieur sur cette This technical problem is solved by the present invention, which relates to a wiper bottle with removable suction pipe, characterized in that this suction pipe consists of two tubular parts - screwable one into the other of which one is pressed into a corresponding opening in the wiper bottle, so that it is applied by a shoulder against the inner side of the wiper bottle, and the other, which carries the olive, is screwed into the wiper bottle; outside on this

Entre les deux parties il peut y avoir, autour de ladite ouverture du flacon essoreur, une rondelle de Between the two parts there may be, around said opening of the wiper bottle, a washer of
garniture assurant l'étanchéité.sealant seal.
Les deux parties peuvent être en une matière plastique. Le dessin annexé montre bien comment le flacon essoreur de l'invention peut être réalisé. Il représente le col (2) du flacon essoreur (1) avec l'ouverture latérale (3) dans laquelle est enfoncée la tubulure d'aspiration. Cette dernière est constituée de deux parties tubulaires en The two parts can be made of a plastic material. The accompanying drawing shows how the wiper bottle of the invention can be made. It represents the neck (2) of the wiper bottle (1) with the lateral opening (3) in which is pressed the suction pipe. The latter consists of two tubular parts in
matière plastique. L'une d'elle, à savoir la partie tubu- plastic material. One of them, namely the tubular part
laire courte (4), est enfoncée de l'intérieur à travers l'ouverture (3) et a un épaulement (5) reposant contre le côté intérieur du col (2); l'extrémité qui sort de l'ouverture et fait saillie à l'extérieur porte un filetage. L'autre partie -tubulaire (6) est taraudée à une extrémité et elle short line (4), is pressed from the inside through the opening (3) and has a shoulder (5) resting against the inner side of the neck (2); the end protruding from the opening and projecting outwards carries a thread. The other -tubular part (6) is threaded at one end and it

laire (4); son autre extrémité est munie d'une olive, laquelle peut avoir un grand diamètre intérieur. La rondelle de garniture (7) est serrée sous l'effet du vissage des deux parties tubulaires (4) et (6) entre le côté extérieur du col (2) entourant l'ouverture (3) et la face frontale de l'élément tubulaire (6), et elle rend ainsi la jonction (4); its other end is provided with an olive, which may have a large inside diameter. The packing washer (7) is tightened by screwing the two tubular parts (4) and (6) between the outside of the neck (2) surrounding the opening (3) and the front face of the element tubular (6), and thus makes the junction
