Description

La invention se réfère à un dispositif pour la fermeture de capsules en deux parties, par exemple des capsules pour usage médicinal, comprenant un moyen de support pour une partie supérieure de la capsule et des moyens d'application sur ladite partie supérieure de la capsule d'un liquide destiné à provoquer la jonction réciproque entre la partie supérieure de la capsule et la partie inférieure de celle-ci.The invention relates to a device for closing two-part capsules, for example capsules for medicinal use, comprising a support means for an upper part of the capsule and means of application on said upper part of the capsule. a liquid intended to cause the reciprocal junction between the upper part of the capsule and the lower part thereof.

L'invention concerne également un procédé pour la fermeture de capsules en deux parties, par exemple des capsules pour usage médicinal, comprenant les phases de distribution sur une des deux parties de capsule d'un liquide destiné à provoquer la jonction réciproque des deux parties de la capsule et ensuite d'union des deux parties de la capsule pour en provoquer la jonction par collage.The invention also relates to a method for closing two-part capsules, for example capsules for medicinal use, comprising the distribution phases on one of the two capsule parts of a liquid intended to cause the reciprocal junction of the two parts of the capsule. the capsule and then union of the two parts of the capsule to cause the joining by gluing.

Dans le domaine pharmaceutique, on utilise fréquemment, comme récipients de médicaments en poudre, des capsules réalisées en gélatine ou, selon la technique la plus récente, en amidon. Ces capsules présentent une première partie ou corps, à l'intérieur de laquelle est introduite la poudre à conditionner, et une calotte supérieure de fermeture qui doit être enfilée sur le corps et soudée à celui-ci. Pour le soudage ou la jonction des deux parties de la capsule, on utilise des liquides de diverse nature, en fonction du type de substance employée pour la réalisation de la capsule. Par exemple, dans le cas de capsules réalisées en amidon, il suffit d'appliquer sur le bord interne de la partie supérieure de la capsule une faible quantité d'eau ou d'un autre solvant, qui provoque un ramollissement de l'amidon. En enfilant ensuite la partie supérieure de la capsule sur le corps de celle-ci et en faisant sécher, on obtient une fermeture efficace et fiable de la capsule elle-même.In the pharmaceutical field, capsules made of gelatin or, according to the most recent technique, starch, are frequently used as containers for powdered medicaments. These capsules have a first part or body, inside which is introduced the powder to be packaged, and an upper cap which must be slipped on the body and welded thereto. For welding or joining the two parts of the capsule, liquids of various kinds, depending on the type of substance used for producing the capsule. For example, in the case of capsules made of starch, it is sufficient to apply on the inner edge of the upper part of the capsule a small amount of water or another solvent, which causes a softening of the starch. Then by putting the upper part of the capsule on the body thereof and drying, we obtain an effective and reliable closure of the capsule itself.

Pour obtenir une fermeture correcte de la capsule et pour éviter une détérioration aussi bien du contenu de la capsule que de son enveloppe externe, il est nécessaire que le moyen liquide appliqué pour la jonction successive des deux parties soit distribué de manière uniforme et en quantité correcte, en éliminant l'excédent susceptible de provoquer l'adhésion des capsules adjacentes ou encore une détérioration du contenu de la capsule elle-même.
Dans ce but, on a étudié un dispositif (décrit dans DE-A-3735260) qui présente une série de buses qui vaporisent le liquide sur le bord de la partie supérieure de la capsule et un système d'aspiration qui aspire le surplus de liquide vaporisé sur la capsule avant de procéder à l'accouplement des deux parties. Ce dispositif est extrêmement complexe, entre autre parce qu'il nécessite des moyens de compression du liquide et des moyens d'aspiration de celui-ci.To obtain a correct closure of the capsule and to prevent damage to both the contents of the capsule and its outer shell, it is necessary that the liquid means applied for the successive joining of the two parts is distributed uniformly and in the correct amount. , eliminating the excess likely to cause the adhesion of the adjacent capsules or a deterioration of the contents of the capsule itself.
For this purpose, a device (described in DE-A-3735260) has been studied which has a series of nozzles which vaporize the liquid on the edge of the upper part of the capsule and a suction system which sucks the excess liquid sprayed on the capsule before coupling the two parts. This device is extremely complex, among other things because it requires liquid compression means and suction means thereof.

Le but de la présente invention est de réaliser un dispositif du type mentionné dans le préambule de la revendication principale, qui permette d'obtenir une application correcte du liquide sur la partie supérieure de la capsule d'une manière plus simple et plus fiable que pour tes dispositifs de type traditionnel.The object of the present invention is to provide a device of the type mentioned in the preamble of the main claim, which allows to obtain a correct application of the liquid on the upper part of the capsule in a simpler and more reliable way than for your traditional type devices.

En réalité, le dispositif selon l'invention se base sur un nouveau principe d'application du liquide, lequel utilise des moyens d'application comprenant un organe absorbant qui prélève par capillarité le liquide dans un récipient et le distribue sur la partie supérieure de la capsule, en correspondance du bord de jonction de ladite partie supérieure avec le corps de la capsule. De ce fait, le dispositif selon l'invention ne comporte pas de moyens de compression du liquide ni des moyens d'aspiration de celui-ci. Par ailleurs, il n'est pas nécessaire de réaliser des organes mécaniques de petites dimensions avec buses de vaporisation et orifices d'aspiration, comme cela est nécessaire dans les dispositifs de type connu. Tout le processus de prélèvement du liquide et d'application de celui-ci s'effectue de manière passive en exploitant les caractéristiques physiques d'un moyen absorbant, qui peut être constitué par exemple par une peau synthétique chamoisée, fibre de coton ou matériau similaire.In fact, the device according to the invention is based on a new principle of application of the liquid, which uses application means comprising an absorbent member which removes the fluid in a container by capillary action and distributes it on the upper part of the container. capsule, in correspondence of the joining edge of said upper part with the body of the capsule. Therefore, the device according to the invention does not include liquid compression means or suction means thereof. Moreover, it is not necessary to make mechanical devices of small dimensions with spray nozzles and suction ports, as is necessary in devices of known type. The entire liquid collection process and application thereof is carried out passively by exploiting the physical characteristics of an absorbent means, which may be constituted for example by a buff synthetic skin, cotton fiber or similar material .

Selon une forme de réalisation pratique, le dispositif comprend une tige en correspondance de l'extrémité supérieure de laquelle est disposé un élément en matière absorbante qui reçoit le liquide par capillarité à partir d'un réservoir placé au-dessous. Par exemple, en correspondance de ladite extrémité supérieure de ta tige peut être disposé un élément disco de en matière absorbante, dont le diamètre correspond au diamètre du bord de la partie interne supérieure de la capsule, de telle manière que cette dernière puisse être enfilée sur l'élément disco de et être mouillée uniformément par celui-ci le long de toute la circonférence du bord d'accouplement avec le corps de la capsule. L'élément disco de en matière absorbante peut être en contact avec un élément linéaire en forme de bande qui s'étend le long de ta tige à partir de ladite extrémité supérieure jusqu'à un réservoir placé au-dessous, pour te prélèvement du liquide contenu dans ledit réservoir. L'élément longitudinal peut être réalisé sous forme de bande logée dans des sièges longitudinaux pratiqués dans un axe central de logement, entouré par un organe cylindrique externe de fermeture.
La partie supérieure de la capsule doit être prélevée par un dispositif d'alimentation par l'intermédiaire d'un moyen de support approprié qui permet de présenter successivement ladite partie de capsule aux moyens d'application du liquide et ensuite au corps de ta capsule préalablement rempli de poudre ou d'une autre substance à conditionner.
Le moyen de support peut comprendre, conformément à l'invention, une cavité ou un logement muni d'un joint annulaire, dans lequel la partie supérieure de la capsule peut être insérée avec une légère interférence sous l'effet d'un simple mouvement d'abaissement du moyen de support sur la partie de capsule prédisposée sur le dispositif d'alimentation. Le joint annulaire maintient la partie supérieure de la capsule pendant tout le temps nécessaire pour l'application du liquide sur sur le bord de celle-ci et jusqu'à l'adhésion de la partie supérieure de la capsule sur le corps de la capsule. A ce stade, au moyen d'un extracteur ou en créant une surpression dans la cavité du moyen de support, on provoque le débo tement de la partie de capsule supérieure hors de cette cavité; ladite partie supérieure reste adhérente au corps de capsule supportée de manière appropriée dans un siège de retenue.According to a practical embodiment, the device comprises a rod corresponding to the upper end of which is disposed a member of absorbent material which receives the liquid by capillarity from a tank placed underneath. For example, in correspondence of said upper end of the rod may be disposed a disco member of absorbent material, the diameter of which corresponds to the diameter of the edge of the upper inner portion of the capsule, so that the latter can be threaded on the disco element to and be wetted uniformly therethrough along the entire circumference of the coupling edge with the body of the capsule. The disco member of an absorbent material may be in contact with a web-like linear member extending along the stem from said upper end to a reservoir below, for sampling the liquid. contained in said tank. The longitudinal member may be made in the form of a strip housed in longitudinal seats formed in a central axis of housing, surrounded by an outer cylindrical closure member.
The upper part of the capsule must be taken by a feeding device via a suitable support means which makes it possible to successively present said capsule part to the means for applying the liquid and then to the body of the capsule beforehand. filled with powder or other substance to be packaged.
The support means may comprise, according to the invention, a cavity or a housing provided with an annular seal, in which the upper part of the capsule can be inserted with a slight interference under the effect of a simple movement of lowering the support means on the capsule portion predisposed on the supply device. The annular seal maintains the upper portion of the capsule for as long as is necessary for applying the liquid to the edge thereof and until the top of the capsule adheres to the body of the capsule. At this stage, by means of an extractor or by creating an overpressure in the cavity of the support means, it causes the dislocation of the upper capsule portion out of this cavity; said upper portion remains adhered to the capsule body suitably supported in a restraint seat.

Dans une forme possible de réalisation, il est prévu un organe porteur équipé d'un ou plusieurs desdits moyens de support et prévu pour se positionner dans une première position en correspondance d'un dispositif d'alimentation des parties supérieures de capsule et une deuxième position en correspondance des moyens correspondants d'application du liquide. De cette position, après avoir mouillé le bord de toutes les parties de capsule supportées par les différents moyens de support de l'organe porteur, ce dernier est déplacé par translation dans une troisième position en correspondance de moyens correspondants de support des corps ou partie inférieures de la capsule. L'abaissement de l'organe porteur équipé des moyens de support des parties supérieures de capsule provoque la fermeture simultanée de tous les corps de capsule placés au-dessous.In one possible embodiment, there is provided a carrier member equipped with one or more of said support means and adapted to be positioned in a first position in correspondence with a device for feeding the upper parts of the capsule and a second position. in correspondence of the corresponding means for applying the liquid. From this position, after wetting the edge of all the capsule parts supported by the various support means of the carrier member, the latter is moved by translation in a third position in correspondence of corresponding means for supporting the body or lower part of the capsule. Lowering the equipped carrier means for supporting the upper parts of the capsule causes the simultaneous closure of all the capsule bodies placed below.

L'invention sera mieux comprise en suivant la description qui va suivre et le dessin annexé qui montre une exemplification pratique non limitative de l'invention elle-même. Dessin sur lequel:

The invention will be better understood by following the description which follows and the accompanying drawing which shows a practical non-limiting exemplification of the invention itself. Drawing on which:

Sur le dessin, le numéro de référence 1 indique un dispositif d'alimentation sur lequel se trouvent plusieurs capsules de fermeture ou partie supérieures S de capsule, provenant d'un récipient approprié. Chacune de ces parties S est prélevée par un moyen de support correspondant indiqué génériquement par 3 et représenté de manière plus détaillée sur la Fig. 2. En pratique, il est possible de prévoir un organe porteur 5, par exemple sous forme d'une barre s'étendant perpendiculairement au plan du dessin, sur lequel est appliquée une série de moyens de support 3.
Avec un mouvement d'abaissement suivant le flèche f3 (Fig. 2), chaque moyen de support 3 est enfilé sur une partie supérieure S de capsule placée au-dessous. En pratique, il est possible de prévoir plusieurs dispositifs d'alimentation 1 en parallèle, de sorte qu'une seule course d'abaissement suivant f3 de l'organe porteur 5 permet de prélever un nombre de parties S de capsule correspondant au nombre de moyens de support 3. Inversément, on peut également prévoir que l'organe porteur 5 soit asservi à un mouvement d'alimentation intermittent suivant la direction perpendiculaire au dessin des Fig. 1 et 2, de manière qu'avec une combinaison de mouvements de soulèvement et d'abaissement et de translation en direction perpendiculaire à la figure, tous les moyens de supports 3 portés par l'organe porteur 5 puissent être chargés avec des parties S de capsule alimentées par un seul dispositif d'alimentation 1 en position fixe.In the drawing, reference numeral 1 indicates a feeding device on which there are several closure capsules or upper portion S of capsule, coming from a suitable container. Each of these S parts is taken by a corresponding support means indicated generically by 3 and shown in greater detail in FIG. 2. In practice, it is possible to provide a carrier member 5, for example in the form of a bar extending perpendicularly to the plane of the drawing, on which is applied a series of support means 3.
With a lowering movement along the arrow f3 (FIG 2), each support means 3 is threaded onto an upper portion S of capsule placed below. In practice, it is possible to provide several feeders 1 in parallel, so that a single lowering stroke along f3 of the carrier member 5 can take a number of S parts of capsule corresponding to the number of means 3. Inversely, it can also be provided that the carrier member 5 is slaved to an intermittent feed movement in the direction perpendicular to the drawing of FIGS. 1 and 2, so that with a combination of lifting and lowering movements and translation in the direction perpendicular to the figure, all the support means 3 carried by the carrier member 5 can be loaded with parts S of capsule fed by a single feed device 1 in a fixed position.

Comme on peut le voir en particulier sur la Fig. 2, le moyen de support 3 de la partie S de capsule comprend un organe cylindrique 7 formant une cavité 9 avec une gorge 11 dans laquelle est logé un joint 13 annulaire et de section circulaire. Lorsque le moyen de support 3 est enfilé sur la partie S de capsule, celle-ci pénètre dans la cavité 9 et elle est retenue avec une légère interférence par le joint 13 dans la position représentée sur la Fig. 3. Comme on peut le voir sur cette figure, la partie supérieure S de capsule présente un bord d'épaisseur inférieure, destiné à être enfilé sur un bord supérieur correspondant d'un corps de capsule montré en particulier sur la Fig. 7 et indiqué par C. Pour unir de manière stable la partie supérieure S et la partie inférieure C de la capsule, est prévue l'application d'un liquide approprié sur le bord B de ta partie supérieure S de la capsule. Lorsque la capsule est réalisée en amidon, le liquide utilisé peut être de l'eau, ou encore une solution d'eau et d'alcool ou un liquide similaire, qui provoque un ramolissement ou une dissolution partielle de l'amidon dans la zone d'application. Lorsque le bord B de la partie S de capsule a été ainsi humidifié et donc partiellement dissous ou ramolli, il peut être enfilé sur le bord supérieur du corps de capsule C de telle manière que le séchage successif de l'amidon provoque la jonction des deux parties C et S et enferme de manière étanche le contenu P de la capsule.As can be seen in particular in FIG. 2, the support means 3 of the capsule portion S comprises a cylindrical member 7 forming a cavity 9 with a groove 11 in which is housed a seal 13 annular and circular section. When the support means 3 is threaded onto the capsule portion S, it enters the cavity 9 and is held with slight interference by the seal 13 in the position shown in FIG. 3. As can be seen in this figure, the upper capsule portion S has an edge of lower thickness, intended to be threaded onto a corresponding upper edge of a capsule body shown in particular in FIG. 7 and indicated by C. To stably join the upper part S and the lower part C of the capsule, is provided the application of a suitable liquid on the edge B of the upper part S of the capsule. When the capsule is made of starch, the liquid used may be water, or a solution of water and alcohol or a similar liquid, which causes a softening or a partial dissolution of the starch in the d-zone. 'application. When the edge B of the capsule portion S has thus been moistened and thus partially dissolved or softened, it can be threaded onto the upper edge of the capsule body C so that the successive drying of the starch causes the junction of the two parts C and S and sealingly encloses the contents P of the capsule.

Pour appliquer le liquide de manière uniforme et dans la quantité correcte sur le bord B de la partie supérieure S de capsule, il est prévu selon l'invention un moyen d'application indiqué génériquement par 15 et montré en particulier sur les vues en coupe des Fig. 3, 4, 5 et 6. Le moyen 15 comprend une tige constituée par un axe central 17 et un organe cylindrique externe 19. L'axe 17 présente deux replats 21 diamétralement opposés qui forment, avec une chambre cylindrique 23 délimitée par l'organe cylindrique 19, deux sièges longitudinaux pour une bande de matière absorbante indiquée par 25. Comme on peut le voir en particulier sur la vue en coupe longitudinale de la Fig. 6, la bande 25 est disposée en U à l'intérieur des deux sièges 21 diamétralement opposés, alors que dans une section intermédiaire de ladite bande est prévu un trou, de sorte que la bande 25 peut être enfilée sur l'extrémité 29 de l'axe 17 présentant un diamètre réduit, afin d'être maintenue dans une position prédéterminée par rapport à l'axe 17. Dans l'extrémité 29 et dans une partie du corps de l'axe 17 est prévu un trou fileté dans lequel s'engage une vis 31 destinée à bloquer sur l'axe 17 un élément d'extrémité 33. Entre cet élément 33 et le corps de l'axe 17 est disposé un élément disco de 35 en matière absorbante identique ou similaire à la matière de la bande 25, avec laquelle ledit élément disco de est en contact direct. La vis 31 serre l'élément d'extrémité 33 sur la tige 17 de manière à maintenir l'élément disco de 35 en contact étroit avec la bande 25 pour les buts indiqués par la suite. La longueur de l'extrémité 29 et l'épaisseur de la matière formant la bande 25 et l'élément disco de 35 peuvent être calibrées de manière appropriée pour serrer avec la force désirée la matière absorbante et obtenir ainsi la distribution de la quantité correcte de liquide Le moyen d'application 15 est supporté par une traverse 37 qui peut porter une pluralité desdits moyens d'application 15 disposés sur une rangée ou sur plusieurs rangées, et dans tous les cas selon une disposition correspondant à la disposition des moyens de support 3 qui sont présentés au-dessus des moyens 15 et abaissés sur ceux-ci pour amener les parties supérieures S de capsule en contact avec les différents éléments disco des 33 disposés en correspondance des extrémités des différents moyens d'application 15 portés par ta traverse 37.
Au-dessous de la traverse 37 est prévu un récipient (non représenté) dans lequel est contenu le liquide L qui doit être appliqué uniformément sur le bord B des parties S de capsule. La bande 25 a une longueur telle que ses extrémités 25E soient toujours immergées dans le liquide L, lequel est prélevé par capillarité et remonte le long des deux branches de la bande 25 jusqu'à imprégner l'élément disco de 35. Par conséquent, lorsqu'une partie supérieure S de capsule est enfilée sur l'élément disco de 35 (qui dépasse de manière appropriée du profit externe de la tige formée par les organes 17, 19 et 33), sur le bord annulaire B de ladite partie S est distribuée uniformément une quantité de liquide L suffisante pour provoquer le ramollissement ou une dissolution partielle de la matière constituant la capsule. Lorsque le bord B de la partie de capsule s a été mouillé, l'organe porteur 5 avec les moyens de support 3 peut être soulevé et déplacé par translation jusqu'à arriver en correspondance d'un organe 40 qui présente une pluralité de sièges 42 dans lesquels sont logés les corps C des capsules qui doivent être fermées au moyen des parties supérieures S opportunément mouillées le long de leurs bords B. Les moyens de support 37 sont alors soulevés pour enfiler les parties S de capsule sur les corps de capsule C et premettre ainsi la fermeture des capsules ellesmêmes. Sur la Fig. 7 est représentée la phase de fermeture des capsules.
Après que la partie S a été insérée sur le corps C de la capsule, l'organe porteur 5 peut être soulevé suivant la flèche f5 à partir de la position de la fig. 7 pour dégager la partie S du siège 9. Le débo tement de la partie supérieure S de capsule hors du siège 9 peut être facilité au moyen d'un extracteur ou d'une surpression crèe dans ledit siège 9, en agissant à travers l'orifice placé au-dessus (Fig. 2). A ce stade, les différentes capsules sont fermées hermétiquement et prêtes pour être conditionnées. Elles sont extraites de l'organe 40 au moyen d'un extracteur approprié ou autre.
Il est évident que le dispositif selon l'invention peut être utilisé non seulement pour la fermeture de capsules en amidon qui nécessitent l'application de liquides solvants (tels que l'eau ou des mélanges d'eau et d'alcool ou similaires), mais également dans tous tes autre cas dans lesquels, pour la fermeture de la capsule, est nécessaire l'application d'un liquide dont les propriétés physiques sont telles qu'elles permettent le prélèvement dans un réservoir par capillarité.
Selon un autre mode de réalisation modifié, on peut prévoir que la tige 17 avec l'embout 33, la bande absorbante 25 et l'élément disco de 35 soit mobile verticalement à l'intérieur de l'organe cylindrique 19. De cette manière, l'élément disco de 35 pourrait être comprimé de façon cyclique entre le bord supérieur de l'organe cylindrique 19 fixe et l'embout 33 mobile, à chaque opération d'application du liquide sur la partie supérieure S de la capsule. Le pressage de l'élément disco de 35 entra ne la distribution d'une plus grande quantité de liquide.In order to apply the liquid uniformly and in the correct amount to the edge B of the upper capsule portion S, there is provided according to the invention a means of application indicated generically by 15 and shown in particular on the sectional views of FIGS. 3, 4, 5 and 6. The means 15 comprise a rod consisting of a central axis 17 and an outer cylindrical member 19. The axis 17 has two diametrically opposed flats 21 which form, with a cylindrical chamber 23 defined by the organ cylindrical 19, two longitudinal seats for a strip of absorbent material indicated by 25. As can be seen in particular in the longitudinal sectional view of FIG. 6, the strip 25 is U-shaped inside the two diametrically opposed seats 21, while in an intermediate section of said strip is provided a hole, so that the strip 25 can be slipped onto the end 29 of the 17 having a reduced diameter, in order to be maintained in a predetermined position relative to the axis 17. In the end 29 and in a portion of the body of the shaft 17 is provided a threaded hole in which s' engages a screw 31 for locking on the axis 17 an end member 33. Between this element 33 and the body of the shaft 17 is disposed a disco element 35 of absorbent material identical or similar to the material of the strip 25, with which said disco element is in direct contact. The screw 31 squeezes the end member 33 on the rod 17 so as to keep the disc member in close contact with the band 25 for the purposes indicated below. The length of the end 29 and the thickness of the web-forming material 25 and the disco element 35 can be suitably calibrated to clamp with the desired force absorbent material and thus obtain the distribution of the correct amount of liquid The application means 15 is supported by a cross member 37 which can carry a plurality of said application means 15 arranged in a row or in several rows, and in any case according to a provision corresponding to the arrangement of the support means 3 which are presented above the means 15 and lowered thereon to bring the upper parts S of the capsule in contact with the different disco elements 33 arranged in correspondence of the ends of the different means of application 15 carried by your cross member 37.
Below the cross member 37 is provided a container (not shown) in which is contained the liquid L to be uniformly applied to the edge B of the capsule parts S. The strip 25 has a length such that its ends 25E are always immersed in the liquid L, which is taken by capillarity and goes up along the two branches of the strip 25 to impregnate the disco element of 35. Therefore, when an upper portion S of capsule is threaded onto the disco member 35 (which suitably exceeds the external profit of the rod formed by the members 17, 19 and 33), on the annular edge B of said portion S is distributed uniformly an amount of liquid L sufficient to cause the softening or partial dissolution of the material constituting the capsule. When the edge B of the capsule portion has been wet, the carrier member 5 with the support means 3 may be raised and moved by translation to arrive in correspondence of a member 40 which has a plurality of seats 42 in which are housed the body C of the capsules which must be closed by means of the upper parts S appropriately wetted along their edges B The support means 37 are then lifted to thread the capsule portions S onto the capsule bodies C and thereby to close the capsules themselves. In FIG. 7 is shown the closing phase of the capsules.
After the part S has been inserted on the body C of the capsule, the carrier member 5 can be lifted along the arrow f5 from the position of FIG. 7 to disengage the part S of the seat 9. The dislocation of the upper part S of the capsule out of the seat 9 can be facilitated by means of an extractor or an overpressure created in said seat 9, by acting through the orifice placed above it (Fig. 2). At this stage, the different capsules are hermetically closed and ready to be packaged. They are extracted from the member 40 by means of a suitable extractor or other.
It is obvious that the device according to the invention can be used not only for the closure of starch capsules which require the application of liquid solvents (such as water or mixtures of water and alcohol or the like), but also in all your other cases in which, for the closing of the capsule, is necessary the application of a liquid whose properties The physical properties are such that they allow the sampling in a reservoir by capillarity.
According to another modified embodiment, it is possible for the rod 17 with the tip 33, the absorbent strip 25 and the disco element 35 to be vertically movable inside the cylindrical member 19. In this way, the disco element 35 could be cyclically compressed between the upper edge of the cylindrical member 19 fixed and the tip 33 movable, each liquid application operation on the upper part S of the capsule. The pressing of the disco element causes the dispensing of a larger amount of liquid.
