Abstract

The invention relates to the combination of a centrifuge container or bottle and its closing stopper. The stopper is an internally threaded cap (21) carrying an annular groove (25) receiving a ring seal (30). One side of the ring seal abuts on an annular surface directed towards the top of the neck of the bottle when the cap is screwed onto the bottle. The inside of the cap also comprises an integral component which extends into the neck of the bottle for a short distance when the cap has been placed in position. <IMAGE>

Description

La présente invention est relative en général aux centrifugeuses dans lesquelles le produit à centrifuger est placé dans des conteneurs tubulaires plastiques supportés par le rotor des centrifugeuses. Plus particulièrement, la présente invention est relative aux chapeaux ou bouchons utilisés pour obturer le haut de ces conteneurs tubulaires.The present invention relates in general to centrifuges in which the product to be centrifuged is placed in plastic tubular containers supported by the rotor of the centrifuges. More particularly, the present invention relates to the caps or plugs used to close the top of these tubular containers.

Les centrifugeuses sont ordinairement pourvues d'un rotor comportant une série de cavités, usuellement disposées de manière circulaire, et prévues pour recevoir les conteneurs tubulaires recevant l'échantillon à centrifuger. Dans le rotor d'une centrifugeuse type, la ligne d'axe de chaque cavité est orientée angulairement par rapport à l'axe de rotation vertical du rotor, de sorte que le fond du conteneur tubulaire est plus éloigné de l'axe du rotor que le haut du conteneur. Les rotors à conteneurs tubulaires inclinés sont avantageux par le fait qu'initialement, l'échantillon ou produit à centrifuger est collecté au fond du conteneur à une cadence plus rapide que lorsqu'on utilise un conteneur ayant son axe longitudinal perpendiculaire à l'axe du rotor. Durant le fonctionnement du rotor, l'échantillon est contraint de remonter du côté centrifuge (extérieur extrême) de la paroi du tube. Finalement, lorsqu'une vitesse de rotation suffisamment élevée est atteinte, la surface de l'échantillon se trouve presque parallèle à l'axe du rotor. Pour éviter une fuite de l'échantillon, chaque conteneur est pourvu d'un chapeau ou bouchon obturant l'embouchure du conteneur. Il apparaît de manière évidente que si le conteneur utilisé dans un rotor angulaire est initialement plein ou presque plein, une fuite de l'échantillon se produit à partir du haut du conteneur tubulaire, à moins que le bouchon n'assure une obturation adéquate.Centrifuges are usually provided with a rotor comprising a series of cavities, usually arranged in a circular fashion, and designed to receive the tubular containers receiving the sample to be centrifuged. In the rotor of a typical centrifuge, the axis line of each cavity is oriented angularly with respect to the vertical axis of rotation of the rotor, so that the bottom of the tubular container is more distant from the axis of the rotor than the top of the container. Rotors with inclined tubular containers are advantageous in that initially the sample or product to be centrifuged is collected at the bottom of the container at a faster rate than when using a container having its longitudinal axis perpendicular to the axis of the rotor. During the operation of the rotor, the sample is forced to rise on the centrifugal side (extreme outside) of the wall of the tube. Finally, when a sufficiently high speed of rotation is reached, the surface of the sample is almost parallel to the axis of the rotor. To avoid sample leakage, each container is provided with a cap or plug closing the mouth of the container. It is obvious that if the container used in a rotor angle is initially full or almost full, sample leakage occurs from the top of the tubular container, unless the cap provides adequate sealing.

La technique antérieure prévoit de nombreuses solutions pour les problèmes inhérents aux difficultés qui s'opposent à la possibilité d'assurer une obturation efficace. Un grand nombre de ces dispositifs antérieurs inclut des éléments multiples qui doivent être assemblés autour de l'embouchure du conteneur centrifuge, ces éléments étant usuellement au nombre de trois. Ces éléments multiples sont nécessaires en raison des sollicitations non uniformes appliqués au conteneur lorsqu'il est utilisé dans un rotor centrifuge incliné. Les trois composants comprennent habituellement un bouchon central, un joint d'étanchéité annulaire et une bague. Le bouchon central est conçu pour pénétrer jusqu'à un certain degré dans l'embouchure du conteneur ; étant donné que ce bouchon possède un bord faisant face extérieurement et radialement par rapport à l'embouchure, il prend appui sur un joint d'étanchéité annulaire disposé sur le bord de l'embouchure. La bague annulaire qui est vissée femelle sur l'embouchure du conteneur constitue le moyen pour comprimer ledit bord ou rebord de bouchon contre le joint d'étanchéité annulaire.The prior art provides numerous solutions for the problems inherent in the difficulties which oppose the possibility of ensuring effective obturation. Many of these prior devices include multiple elements which must be assembled around the mouth of the centrifugal container, these elements being usually three in number. These multiple elements are necessary due to the non-uniform stresses applied to the container when it is used in an inclined centrifugal rotor. The three components usually include a central plug, an annular seal and a ring. The central stopper is designed to penetrate to a certain degree into the mouth of the container; given that this plug has an edge facing outward and radially with respect to the mouth, it bears on an annular seal placed on the edge of the mouth. The annular ring which is screwed female onto the mouth of the container constitutes the means for compressing said edge or rim of the cap against the annular seal.

Les Brevets US N° 3.434.615 et 3.459.369 représentent également un certain intérêt dans l'exposé de solutions antérieures de ce genre.US Patents Nos. 3,434,615 and 3,459,369 also represent a certain interest in the presentation of previous solutions of this kind.

Bien que ces solutions de la technique antérieure ne soient pas nécessairement dépourvues d'utilité, il n'en est pas moins facile de se rendre compte que les systèmes de la technique antérieure exigent un certain nombre de phases de manipulation quelque peu laborieuses.While these prior art solutions are not necessarily devoid of utility, it is no less easy to realize that the prior art systems require a number of somewhat laborious handling steps.

La présente invention remédie aux inconvénients précités et assure une obturation étanche et efficace pour un conteneur tubulaire formant bouteille destiné à être utilisé dans une centrifugeuse, cette obturation éliminant certaines des opérations de manipulation que l'on rencontre dans les dispositifs antérieurs.The present invention overcomes the aforementioned drawbacks and provides a tight and effective closure for a tubular container forming a bottle intended to be used in a centrifuge, this closure eliminating some of the handling operations that are encountered in prior devices.

L'obturation s'effectue au moyen de deux éléments seulement montés l'un dans l'autre pour la facilité de l'emploi. Le mo- yen d'obturation se présente sous l'aspect hors tout d'un cha- peau avec une jupe extérieure solidaire s'étendant en direction du bas, comportant un filet femelle prévu pour coopérer avec un filet mâle correspondant établi sur le col d'un conteneur centrifuge. Concentriquement et centralement par rapport au cha- peau, il est prévu un autre élément solidaire intérieur s'éten- dant en direction du bas qui pénètre avec une certaine facilité d'ajustement sur une courte distance dans l'embouchure du con- teneur. Une gorge est prévue entre la jupe extérieure et ledit élément intérieur, et est destinée et construite pour retenir un joint annulaire d'étanchéité. Le joint d'étanchéité annulaire, lorsque le bouchon est appliqué de façon appropriée, a sa partie orientée vers le bas en butée contre le bord normalement orienté vers le haut du conteneur, et est comprimé sur ce bord au fur et à mesure qu'on visse le bouchon.The obturation is carried out by means of only two elements mounted one inside the other for ease of use. The shuttering means has the overall appearance of a hat with an integral external skirt extending downward, comprising a female thread intended to cooperate with a corresponding male thread established on the neck. a centrifugal container. Concentrically and centrally with respect to the cap, there is provided another internal integral element extending in the direction of the bottom which penetrates with a certain ease of adjustment over a short distance into the mouth of the container. A groove is provided between the outer skirt and said inner member, and is intended and constructed to retain an annular seal. The annular seal, when the plug is properly applied, has its part facing downwards abutting against the edge normally facing upwards of the container, and is compressed on this edge as and when screw the cap.

The invention is set out below in detail using drawings in which:
  • Figure 1 is a front view of the bottle container provided with a closure cap, according to the present invention.
  • Figure 2 is a partial cross-sectional view along line 2-2 of Figure 1.

  • Figure 5 is a front view of another embodiment of the bottle, with a partial cross section.

Le conteneur selon la présente invention est représentée figure 1 et référencée en 10 dans son ensemble. Les mêmes éléments sont désignés par des repères identiques dans toutes les figures. fond arrondi 12 prevu pour etre dispose dans un logement de forme complémentaire prévu dans une centrifugeuse de type conventionnel (non représentée). La bouteille 11 peut être par exemple et non limitativement en matière polymère, telle qu'un polycarbonate. Il est souhaitaible que son diamètre extérieur soit choisi de façon à s'ajuster avec facilité dans la cavité d'une centrifugeuse.The container according to the present invention is shown in Figure 1 and referenced at 10 as a whole. The same elements are designated by identical references in all the figures. rounded bottom 12 intended to be placed in a housing of complementary shape provided in a centrifuge of conventional type (not shown). The bottle 11 can be for example and not limited to a polymeric material, such as a polycarbonate. It is desirable that its outside diameter be chosen so as to easily adjust in the cavity of a centrifuge.

A l'autre extrémité par rapport au fond 12, la bouteille 11 est pourvue d'une embouchure relativement large 13 qui assure un accès direct à l'intérieur de la bouteille à partir du dessus. L'embouchure 13 se termine par une surface annulaire 14 orientée vers le haut. Le col 15 de la bouteille en dessous de la surface annulaire 14 est pourvu extérieurement d'un filet mâle 16. Il convient de noter que le col 15 est d'un diamètre quelque peu plus petit que la partie de corps principale 17 de la bouteille. Une partie d'épaulement annulaire 18 relie le col précité 15 à la partie de corps principale 17 de la bouteille.At the other end with respect to the bottom 12, the bottle 11 is provided with a relatively wide mouth 13 which provides direct access to the interior of the bottle from the top. The mouth 13 ends with an annular surface 14 oriented upwards. The neck 15 of the bottle below the annular surface 14 is provided externally with a male thread 16. It should be noted that the neck 15 is of a somewhat smaller diameter than the main body part 17 of the bottle . An annular shoulder portion 18 connects the aforementioned neck 15 to the main body portion 17 of the bottle.

Un chapeau 21 est adapté et conçu pour être vissé sur le filet du col de la bouteille. Ce chapeau comporte une jupe extérieure annulaire 22 ayant un filet 23 prévu pour coopérer avec le filet mâle 16 établi sur le col de la bouteille. Le chapeau comporte également une deuxième jupe 24 s'étendant en direction du bas et ayant un diamètre quelque peu plus réduit, définissant ainsi une gorge 25 entre la surface intérieure de la jupe à grand diamètre 22 et la surface cylindrique extérieure de la jupe à petit diamètre 24. La gorge annulaire 25 comporte une surface terminale arrondie de profil arquée prévue de façon à épouser une partie de la surface arquée d'un joint annulaire d'étanchéité 30 positionné dans la gorge annulaire, comme illustré figure 2 notamment. La surface arquée opposée est aplatie contre la surface annulaire orientée vers le haut 14 lorsque le chapeau est vissé sur le col de la bouteille. La gorge 25 étant d'une dimension lui permettant de recevoir avec une facilité d'ajustement le joint annulaire d'étanchéité, on peut discerner un petit épaulement annulaire 31 établi entre la gorge 25 et la jupe solidaire-extérieure s'étendant vers le bas 22. La cote d' épaisseur de la partie du col de la bouteille comportant la surface annulaire orientée en direction du haut 14 est prévue de façon que cette partie s'ajuste dans une partie de la gorge, en retenant ainsi captif à demeure le joint annulaire d'étanchéité. Comme on peut s'en rendre compte d'après la figure 2, l'épaisseur à l'embouchure est légèrement plus importante que 1' épaisseur hors tout du col. On a constaté qu'il est efficace de s'assurer que le joint d'étanchéité annulaire soit retenu solidement captif lorsqu'il se produit une compression de celui-ci.A cap 21 is adapted and designed to be screwed onto the thread of the neck of the bottle. This cap has an annular outer skirt 22 having a thread 23 provided to cooperate with the male thread 16 established on the neck of the bottle. The cap also includes a second skirt 24 extending in the direction of the bottom and having a somewhat smaller diameter, thus defining a groove 25 between the inner surface of the large diameter skirt 22 and the outer cylindrical surface of the small skirt diameter 24. The annular groove 25 has a rounded end surface with an arcuate profile provided so as to match part of the arcuate surface of an annular seal 30 positioned in the annular groove, as illustrated in FIG. 2 in particular. The opposite arcuate surface is flattened against the upwardly facing annular surface 14 when the cap is screwed onto the neck of the bottle. The groove 25 being of a size allowing it to receive with an ease of adjustment the annular seal, we can discern a small annular shoulder 31 established between the groove 25 and the integral-exterior skirt extending downward. 22. The thickness rating of the part of the neck of the bottle having the annular surface oriented in the direction of the top 14 is provided so that this part fits in a part of the groove, in thus retaining permanently the annular seal. As can be seen from Figure 2, the thickness at the mouth is slightly greater than the overall thickness of the neck. It has been found that it is effective to ensure that the annular seal is retained securely captive when compression occurs.

Dans la mise en oeuvre représentée, la jupe 24, conjointement avec le dessous du chapeau, définit une configuration en forme de bol solidaire s'étendant en direction du bas. Le fait que la dite configuration genre bol soit massive entre dans les buts et caractéristiques de la présente invention.In the implementation shown, the skirt 24, together with the underside of the cap, defines a configuration in the form of an integral bowl extending in the direction of the bottom. The fact that the said bowl-like configuration is massive falls within the aims and characteristics of the present invention.

On remarque, dans la mise en oeuvre représentée, que la partie supérieure du chapeau comporte une oreille allongée 41 s'étendant en direction du haut. Cette oreille est destinée à fournir un moyen d'assistance pour visser et dévisser le chapeau comme on le désire. Elle est également utile pour retirer de la cavité de la centrifugeuse une bouteille bouchée, étant donné qu' elle constitue un moyen de préhension pratique.It is noted, in the implementation shown, that the upper part of the hat has an elongated ear 41 extending in the upward direction. This ear is intended to provide a means of assistance for screwing and unscrewing the hat as desired. It is also useful for removing a corked bottle from the centrifuge cavity, since it is a practical means of gripping.

Le diamètre extérieure de la jupe 22 du chapeau est identique au diamètre extérieur de la bouteille. De cette façon, la paroi de la cavité de la centrifugeuse assure une surface support aussi bien pour le chapeau que pour la bouteille.The outside diameter of the skirt 22 of the hat is identical to the outside diameter of the bottle. In this way, the wall of the centrifuge cavity provides a support surface for both the cap and the bottle.

La figure 4 représente clairement l'aspect caractéristique d'une autre réalisation du chapeau, entrant dans le cadre de la présente invention. On note que la surface supérieure du chapeau de cette réalisation comporte une dépression 51. Dans le plan médian de celle-ci, est réalisée une oreille 52 venant affleurer par sa partie supérieure, la surface de dessus 53 du chapeau. La dépression permet le positionnement de doigts de la main de part et d'autre de l'oreille, la bouteille pouvant ainsi être par son chapeau retirée de la cavité d'une centrifugeuse. Lorsque le chapeau est trop petit, l'extraction s'effectue à l'aide de pinces hémostatiques ou de pinces d'horlogerie.Figure 4 clearly shows the characteristic aspect of another embodiment of the hat, falling within the scope of the present invention. It is noted that the upper surface of the cap of this embodiment has a depression 51. In the median plane thereof, an ear 52 is produced which comes to be flush with its upper part, the top surface 53 of the cap. The vacuum allows positioning of the fingers of the hand on either side of the ear, the bottle thus being able to be removed by its cap from the cavity of a centrifuge. When the cap is too small, the extraction is carried out using hemostatic forceps or clockwork forceps.

On remarque que la partie de bord 55 du chapeau est biseautée annulairetnent comme dans la première réalisation.Note that the edge portion 55 of the hat is annularly beveled as in the first embodiment.

Le chapeau ou bouchon selon la présente invention peut également être fabriqué en polycarbonate. Il a été constaté que cette matière polymère est particulièrement utile. D'autres matières ou matériaux connus ou non dans le commerce peuvent se révéler tout aussi utiles. En conséquence, l'invention n'est pas limitée à une fabrication avec du polycarbonate.The cap or cap according to the present invention can also be made of polycarbonate. It has been found that this polymeric material is particularly useful. Other materials or materials known or not in the trade can prove to be just as useful. Consequently, the invention is not limited to manufacture with polycarbonate.

Le chapeau monobloc selon la présente invention assure un support rigide pour le joint annulaire d'étanchéité, et supprime par conséquent la nécessité de manipuler un insert.The one-piece cap according to the present invention provides a rigid support for the annular seal, and therefore eliminates the need to handle an insert.

L'invention ne se limite aucunement à celui de ses modes d'application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; elle en embrasse au contraire toutes les variantes.The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
