Description

DISTRIBUTOR FOR THE EXTRACTION OF A FLUID PRODUCT CONTAINED IN A CONTAINER DESCRIPTION OF THE INVENTION The present invention relates to a dispenser for the extraction of a fluid product contained in a container. A distributor of this type is known from WO 80/02 546. This dispenser or tap is intended more particularly for "bag-in-box" type containers (which combine a flexible inner container in the form of a bag or bladder and a container rigid exterior) comprises a fixed part forming a tap body, comprising a fixing part to the container that is extended towards the outside of the container by a pouring part of general cylindrical shape, opened at both its axial ends and pierced by a hole lateral fluid outlet. This dispenser also comprises a moving part comprising a sealing part of generally cylindrical shape mounted tightly in the pouring part of the fixed part, opened by its internal axial end, closed by its outer axial end and pierced by a hole lateral fluid outlet, and a head part that allows to grab and maneuver the moving part from the outside. The two parts also comprise means designed to define a first axial position of the moving part with respect to the fixed part, in which the lateral holes of the two parts are displaced axially so that they can not be put in coincidence, therefore in communication, whatever the angular position of the moving part with respect to the fixed part and means designed to define a second axial position of the moving part with respect to the fixed part, in which the lateral holes of the two pieces can be put in coincidence, therefore in communication, by rotation of the moving part with respect to the fixed part. A first drawback of this known distributor in which said first axial position is the extraction position and said second axial position is the position of introduction of the moving part with respect to the fixed part consists in the fact that it is not at all foreseen for keep the moving part with certainty in the first axial position while the moving part has not been intentionally maneuvered in view of a first distribution of fluid. A distribution that is either accidental or untimely fluid can not therefore be excluded with certainty. On the other hand, taking into account the structure of this known distributor, the maneuvering of the head part of the moving part, by rotation, in view of the fluid distribution, is not easy, being the head part, in the second part. axial position, hardly accessible in view of its rotation. Furthermore, it is not envisaged and it is not possible, in this known distributor, to bring the moving part from the second axial position to the first axial position, ie to the position in which a rotation of the moving part does not cause fluid distribution. Finally, this known distributor does not present so-called inviolability means that guarantee the user the perfect condition of the container and its contents at the time of purchase. The object of the present invention is to provide a distributor for the extraction of a fluid product contained in a container, distributor which avoids the drawbacks described above of the known dispensers. The distributor object of the invention for the extraction of a fluid product contained in a container comprises a fixed part comprising a fixing part to the container that is extended towards the outside of the container by a pouring part of general cylindrical shape, opened by its two axial ends, and punctured by a lateral outlet hole of fluid. This dispenser also comprises a moving part comprising a sealing part of generally cylindrical shape mounted tightly in the pouring part of the fixed part, opened by its internal axial end, closed by its outer axial end and pierced by a hole lateral fluid outlet; and a head part that allows to grasp and maneuver the moving part from the outside. The moving part is mounted movable in axial translation and in rotation in the fixed part. The fixed part and the moving part comprise means designed to define a first axial position of the moving part with respect to the fixed part, in which the lateral holes of the two parts are displaced axially so that they can not be put in coincidence , whatever the angular position of the moving part with respect to the fixed part, and means for defining a second axial position of the moving part with respect to the fixed part, in which the side holes of the two parts can be placed in coincidence by rotation of the moving part. In the dispenser according to the invention, said first axial position of the moving part is the maximum sinking position of the moving part in the fixed part and said second axial position is the removal position of the moving part of the fixed part. The first axial position of the moving part is defined by a band of inviolability that, while not being torn off, joins the head part of the moving part to the fixed part.

The second axial position of the moving part is defined by means of seaming designed to allow a rotation of the moving part in this second position. Preferably, the tamper-evident band connects the head part of the movable part to a snap-in engagement ring on the fixed part. Thus, the movable part (sealing part and head part) can be made in one piece by molding with the tamper-evident band and with the hooking ring, and this assembly can be assembled with the fixed piece molded separately. , the sealing part of the movable part being embedded in the pouring part of the fixed part, the two parts being joined to each other by seaming the hook of the moving part behind an exterior bead formed on the fixed piece. Advantageously, the head part of the movable part has an outer gripping flange and the tamper-evident band joins said outer flange to the fixed part, preferably to the hooking ring cooperating by seaming with the fixed part. Preferably, the outer rim of the head part, the tamper-evident band and possibly the hook of the moving part and the fixing part of the fixed part have substantially the same outer diameter, which gives the distributor assembly, before of the first opening, a cylindrical general outer shape, that is to say a substantially smooth outer shape, without protruding parts. The lateral hole provided in the pouring part of the fixed part can advantageously have a pouring spout, preferably approximately radial, which allows a regular pouring regardless of the flow regulated by a more or less important coating of the lateral holes of the two distributor parts. The seaming means defining the second axial position of the movable part with respect to the fixed part can advantageously comprise an internal weatherstrip on the fixed part and an outer weatherstrip on the sealing part of the movable part. The inner weatherstrip is advantageously formed on a skirt that extends the pouring part of the fixed part towards the interior of the container. Preferably, the cylindrical sealing part of the movable part has at least one recess extending from the inner end of the sealing part in an axial depth such that said recess is displaced axially with respect to the lateral hole of the fixed part in the first axial position of the moving part and can, by rotation of the moving part, in the second axial position of the latter, be put in coincidence with the lateral hole of the fixed part. According to a preferred embodiment, two diametrically opposed recesses are provided in the sealing part of the moving part. This allows, in the second axial position of the moving part, to put the one or the other of these two recesses in coincidence with the lateral hole of the fixed part, by a rotation movement of less than 180 ° in one direction or in the other. other. Furthermore, these two recesses give the sealing part, in the vertical of its seaming seam, a flexibility that favors its seaming in the second axial position. In the case where the distributor is intended to equip a container containing a liquid, it may be advantageous to provide, in the pouring part of the fixed part, in a position diametrically opposite the side hole of this part, one or more ventilation holes which allow, as the liquid flows from the container, the entry of a corresponding volume of air into the interior of the container, thus preventing the formation, inside the container, of a depression that could disturb the regular flow of the liquid. Referring to the attached schematic drawings, an illustrative and non-limitative embodiment of a distributor according to the invention will be described in more detail below.; in the drawings: Figure 1 is a perspective view of a drum equipped with the dispenser according to the invention; Figure 2 is a front elevational view of the distributor, before tearing off the tamper-evident band; Figure 3 is a section according to III-III of Figure 2; Figure 4 is an exploded perspective view of the dispenser of Figure 2, showing its two constituent elements and the neck of the drum; Figure 5 is a view analogous to that of Figure 2 after stripping the band of inviolability and traction on the moving part; Figure 6 is a section according to VI-VI of Figure 5; Figure 7 is a section analogous to that of Figure 6, after rotation of the moving part so that the exit holes of the moving part and of the fixed part coincide. As illustrated by the drawings, the dispenser 1 according to the invention for the extraction of fluid, for example of liquid, from a container 2 represented in FIG. 1 in the form of a drum of plastic material, consists of two elements 3 and 4, namely an element 3 intended to be fixed to the neck 5 of the container 2 and an element 4 cooperating with the element 3 for controlling and regulating the extraction of the fluid contained in the container 2. The element 3 comprises a part 6 for fixing to the neck 5, composed of an outer skirt 7 provided with an internal thread 8, and an inner skirt 9 which cooperates with the inner surface of the neck to ensure the sealing between the element 3 and the neck 5. The outer skirt 7 has, at a distance above the thread, an inward projection, which forms an annular step 10. Above the step 10, the outer skirt 7 it has an outer annular gasket 11 and then reaches the inner skirt 9 by an inner annular rim 12 extending radially inwards beyond the inner skirt 9. The fastening part 6 is extended, at the point of the inner edge of the inner rim. flange 12, axially upwards in the figures, ie towards the outside of the container 2, by a pouring part 13 of general cylindrical shape. The pouring part 13 laterally presents, at a distance above the rim 12, a liquid flow orifice 14 located approximately halfway from the part 13. The hole 14 is surrounded by a spout peak 15 that extends radially outwards. In a position diametrically opposite the orifice 14, the pouring part 13 has an air inlet hole 16 located, according to the axis of the pouring part 13, approximately at the level of the lower edge of the hole 14. A cylindrical skirt 17 of small length which At its lower end it has a circular row of inner weatherstrips 18 extending downwards from the rim 12, so that the inner ends of the weatherstrips 18 are located substantially on the downward extension of the inner surface of the part Finally, an inviolability ring 19 having an internal hooking strip 20 (or several inner hooking pins) is connected by breakable bridges 20a to the lower edge of the outer skirt 7 of the element 3. The element 4 comprises a sealing part 21 which is in the form of a cylindrical skirt forming a protrusion on a bottom 22 which closes the skirt 21 po r its upper end. The bottom 22 is extended radially outwards, beyond the skirt 21, in the form of an annular outer flange 23. The skirt 21 has two diametrically opposed notches 24 extending from the lower end of the skirt towards above noticeably to half height of the latter. The skirt 21 also has, on its lower edge, an outer weatherstrip 25 that extends over the entire contour of the skirt 21, except at the point of the notches 24. A band of tamper-proof inviolability 26, made in one piece with the rim 23 of the bottom 22, it is joined to said rim by an annular zone 27 of less resistance. The tamper-evident band 26 has, as shown in FIGS. 1 to 4, a gripping leg 28 which makes it possible to grasp one end of the strip 26 in view of its removal. At its lower end, the cylindrical inviolability band 26 is joined by an annular zone 29 of less resistance to a hook ring 30 provided internally with an annular bead 31 intended to cooperate by snap-fastening with the outer bead 11 of the fixing part 6. of the element 3. The element 3 is made in one piece with the inviolability ring 19, by molding a plastic material. The element 4 is made in one piece with the tamper-evident band 26 and the hooking ring 30, also by molding thermoplastic material. Before placing the distributor 1 formed by the two elements 3 and 4 on the neck 5 of the container 2, the two elements 3 and 4 are assembled, inserting the skirt 21 of the element 4 into the pouring part 13 of the element 3 until, after postage of the inner weatherstrip 18 of the element 3 by the outer bead 25 of the element 4, the engagement ring 31 of the element 4 is snapped under the bead 10 of the element 3, pressing on the step 10. In this position which is visible in 2 and 3, the upper edge of the recesses 24 of the skirt 21 of the element 4 is located lower than the lower edge of the hole 14 of the pouring part 13 of the element 3. Preferably, this assembly of the two elements 3 and 4 can be carried out with a well-defined angular positioning of the element 4 with respect to the element 3, namely in such a way that the stripping leg 28 of the tamper-evident band 26 is in the vertical of the pouring spout 15 from hole 14 (see figure 3). For the assembly of the distributor 1 thus assembled from the elements 3 and 4 on the container 2 whose neck 5 has an external thread 32 and, below the latter, an external seaming bead 33 and an outer support flange 34, The distributor 1 is threaded onto the neck 5. The height of the rim 12 of the element 3, at the point where this edge 12 comes to rest on the upper edge of the neck 5, is advantageously chosen in such a way that when the distributor 1 is threaded to bottom on the neck 5, the inner seal 20 of the tamper-evident ring 19 being snapped under the outer bead 33 of the neck 5, the distributor 1 occupies an angular position well determined in advance with respect to the neck 5. In the embodiment shown, the pouring spout 15 which lies below the stripping leg 28 of the inviolability band 26 thus occupies an angular position such that when the drum 2 is placed in such a way that the distributor 1 is placed lower, the spout 15 is oriented downwards. To ensure tightness between the two elements 3 and 4, it is necessary that the outer diameter of the skirt 17 of the element 4 and the inner diameter of the pouring part 13 of the element 3 are adapted so that the skirt 21 of the element 4 is assembled with tight fit in the pouring part 13 of the element 3. While the tamper-evident band 26 has not been torn off, the element 4 occupies the position according to figures 1 to 3 and, any extraction, voluntary or not, is impossible. For the first opening, the tamper-evident band 26 is pulled out and the head 22 of the element 4 is pulled out to extract the latter until the outer weatherstrip 25 of the element 4 is snapped behind the inner weatherstrip 18 of the element 3. In this position, none of the two recesses 24 is in coincidence with the hole 14. It is only by a rotational movement printed on the element 4, in one direction or the other, that it is possible to carry the one or the other of the two recesses 24 facing the hole 14, which allows an extraction with adjustable flow rate by the degree of coating of this recess 24 with the hole 14. At the same time, the opposite recess 24 coincides with the hole 16, thus allowing an air intake into the container as the fluid contained in the container flows through the orifice 14 and the spout 15 (see figure 7). When the required amount of fluid has been extracted, the user can stop the extraction by rotating the element 4 so that the notch 24 does not coincide with the hole 14, which interrupts the pouring. In order to improve the safety against an untimely spillage, the user can on the other hand press on the element 4 to bring the latter into the position of introduction according to figure 3, position in which, even by rotation of the element 4, it is not possible to carry the recesses 24 coinciding with the hole 14, due to the axial displacement of the recesses with respect to the hole. Of course, the embodiment represented and described has been given only by way of illustrative and non-limiting example and numerous modifications and variants are possible within the framework of the invention. Thus, the distributor 1, instead of being fixed by threading, could also be fixed by seaming on a neck shaped accordingly. In this case, in order to ensure a correct angular positioning of the distributor with respect to the container, it is possible to provide, at the same time in the fixing part 6 of the element 3 and on the neck 5 of the container, angular positioning means cooperating the one with the other so that they only allow a seaming of the distributor on the neck in the angular position sought. The seaming that defines the extraction position of the movable element 4 could be carried out by means other than the seals 18 and 25. The tamper-evident band 26 could cooperate directly with the element 3, which would suppress in engagement ring 30. The distributor of according to the invention it can be used for the extraction of any fluid product that can be distributed by pouring from a container. In the case of liquids, the ventilation hole 16 can advantageously be provided to prevent the establishment of a depression in the container, which could disturb the regular extraction. The dispenser according to the invention can also be used, for example, for the pouring of powders or other fluid solid products, for example in the form of microbeads. In this case, a ventilation hole may be superfluous. On the other hand, the dispenser according to the invention could also have a different external general shape than the cylindrical shape shown.

It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention. Having described the invention as above, property is claimed as contained in the following:
