Description

[0001] UNIVERSAL PLASTIC DISPENSING TAP EQUIPPED WITH AN

[0002] OPENING SYSTEM, WITH PRODUCT ANTI -COUNTERFEITING

[0003] SYSTEM, FOR CONNECTION SYSTEMS

[0004] The present invention relates to a tap for dispensing liquids from containers , in particular containers of the so-called "Bag- In-Box" type (hereinafter referred to as BIBs ) .

[0005] In particular, the invention relates to a dispensing tap made entirely of plastic material , adaptable to existing connection systems on the market , equipped with a unidirectional opening and therefore being anti-counterfeiting .

[0006] Many systems are used to dispense liquids from a disposable BIB package consisting of a flexible bag in a cardboard box .

[0007] Typically, these systems include a bag with an accessory, commonly called a tap, through which the filling and subsequent dispensing of the fluid contained within the BIB package occurs . A connector is generally provided between the spout and the service line of the pump or other type of beverage mixing and dispensing system.

[0008] Various tap configurations are known in the art (e.g. EP-A1-3371095, US-B2-10994912 or US-B2-

[0009] 7487951) , which constitute known embodiments of this product .

[0010] In any case, there are also other similar configurations of a known type, illustrated in patent WC-A1-2016007818, relating to taps operated by connectors already present on the market.

[0011] There are two types of connectors:

[0012] - Connector with screw-on system hook-up, as illustrated in FIG. 8, 9, 24, 25 and 26;

[0013] Connector with quick-release coupling system , as illustrated in FIG. 11, 12, 19, 20, 21, 22 and 23.

[0014] All of these known taps have a roughly similar operating / actuation principle.

[0015] Referring to FIG. 20, 21, 22, 23 24, 25 and 26, they illustrate in detail the operating principle of the tap present on the market and the general opening principle of the tap + connector system, in order to allow the dispensing of the liquid contained inside a container, preferably of the BIB type.

[0016] It should be considered that the tap of the present invention also necessarily has to adapt to the connectors present on the market, and therefore has to respect the opening steps of each type of connector, exploiting a more innovative and effective technology in terms of general performance compared to the old technologies present on the market today which have numerous limitations, including technical ones.

[0017] By first analyzing the screw connector 7 of FIG. 24, the following system activation steps can be found :

[0018] - step 1: screw connector of FIG. 24, i.e. screw connectors 7 present on the market;

[0019] - step 2: screwing of the connector 7 of FIG. onto a nozzle 12 of FIG. 24 and 25 on which the lower thread geometries 12.7 and upper thread geometries

[0020] 12.6 are obtained (FIG. 24) necessary to allow the screwing of the connector 7 (FIG. 25) , due to the operational coupling between the thread 7.2 of FIG. 24 obtained on the connector and the two threads

[0021] 12.7 12.6 of FIG. 24 obtained on the tap of FIG. 25 due to the operational coupling 7.2 - 12.6 / 12.7. In this step, the opening of the connector 7 also occurs due to the push of the geometry of a first central pin / protuberance 11.1 on the central pin 7.5 which slides inside the central turret 7A of FIG. 25 of the screw connector 7, which serves to open the delivery channel of the connector 7 of FIG. 25. The central pin 7.5 of FIG. 25 can move back by a predetermined amount "X" of FIG. 25, then it locks due to the cooperation with a geometric mechanical block inside the connector itself (not shown) present inside the central turret 7A of FIG. 25. Simultaneously the connector 7 of FIG. 25 goes into operational sealing with the tap due to the sealing geometries present on both systems (tap 10.3 of FIG. 24 and connector 7.6 of FIG. 24 with the sealing assembly 7.6-10.3) of FIG. 25 and due to the interference between the sealing geometries of the valve 11.2 and the internal body 10.2 (10.2-11.2 of FIG. 25) which in this step keep the valve 11 still in its closed position. The opening quota of the central turret of the screw connector 7A of FIG. 25 is controlled by a mechanical stop inside the central turret 7A (not shown) , for a pre-established quota "X" of FIG. 25 due to the cooperation of the mechanical stop present inside the central pin of connector 7.5 of FIG. 25 (not illustrated) ;

[0022] - step 3: complete screwing of the connector 7 onto the tap nozzle illustrated in FIG. 26 and simultaneous opening of the tap due to the thrust 11.1-7.5 which, having reached the mechanical stop level of the connector, moves the internal valve 11 of FIG. 26 to the open position, overcoming the interference (10.2-11.2 of FIG. 25) generated between the coupling of the sealing geometry of the internal valve 11.2 of FIG. 25 with the internal sealing geometry of the internal body 10.2 of FIG. 2 5 and allowing the internal valve 11 to move to the open position and consequently allowing the tap + screw connector system to both remain locked in the open position, thus allowing the liquid contained inside the BIB to be dispensed. The closing steps of the system follows the reverse steps just described. It should be noted that the closing of the internal valve 11 of FIG. 26 is carried out due to the flexible teeth 10.1 of FIG. 26 obtained on the internal body 10. These teeth sometimes not have the elasticity and strength necessary to allow the self-closing of the internal valve 11 and cause problems of liquid loss as they are not able to generate the self-closing force necessary to allow the correct liquid seal of the two components 10 and 11 of FIG. 26 and above all they limit the passage of liquid from the cap as the base where the teeth 10.1 of FIG. 26 are obtained must be structured in such a way as to be able to resist the thrust of the valve and the consequent opposing thrust action of the teeth 10.1 which try to close the internal valve 11 of FIG. 26 until their elasticity / elastic memory allows it.

[0023] As for the quick-release connector version 9 illustrated in FIG. 20, 21, 22 and 2 3, instead, the operating principle can generally be described in this way:

[0024] - step 1: quick-release connectors 9 available on the market in FIG. 20;

[0025] - step 2: fitting of the connector 9 of FIG. 21 onto the external disc-shaped coupling geometries of the nozzle 12.5 and 12.4 of FIG. 20 by means of the operational coupling of the protuberances 9.1 and 9.2 obtained on the interlocking connector itself and illustrated in FIG. 20 to allow for stable simultaneous anchoring of the connector to the tap 9.1-12.4 and 9.2-12.5 available on the market;

[0026] - step 3: manual push made by the end customer with a vertical force "FV" of FIG. 22 on the central turret 9A of the connector, which moves in axis. The central turret 9A of the connector 9 of FIG. 22 allows the same connector 9 to enter into operational seal with the dispensing tap of FIG. 22 and, at the same time, due to the operational contact between the geometry of the first central pin 11.1 of the internal valve all of FIG. 22 with the central pin 9.5 of the interlocking connector 9, it allows the opening of the connector. Also in this case, the opening dimension of the central pin 9.5 of FIG. 22 is limited to a dimension "Y" due to the cooperation of the internal mechanical stop geometries of the central pin 9.5 of FIG. 22 (not illustrated) present inside the movable turret "system" 9A of FIG. 22. At this stage, the connector has moved from a closed to an open position and is operationally engaged with the internal geometries of the tap present on the market as illustrated in FIG. 22;

[0027] -step 4: the turret 9A of the connector continues its descent to complete the possible movement stroke "Z" of FIG. 21. The central pin 9.5 of FIG. 23 is mechanically blocked in its retraction stroke "Y" of FIG. 22 and the central turret 9A continues to push downwards, and therefore to transmit the vertical force FV applied by the external final operator, to the assembly formed by the particular Body 10 and the internal valve 11. Due to the operational coupling between the first central pin 11.1 of the internal valve 11 of the tap of FIG. 23 and the central pin 9.5 of the central turret 9A (coupling 11.1-9.5 of FIG. 22) overcomes the locking interference between the internal valve 11 and the body 10 (by means of the interference coupling of the 2 sealing geometries 10.2-11.2 of FIG. 23 which work when the tap of FIG. 22 is in the closed position) and moves forward the internal valve 11 of FIG. 23 allowing the opening of the tap of FIG. 23 and, once the "Z" stroke of the central turret 9A of FIG. 21 has ended, it also has simultaneously moved forward the body 10 on which the internal valve 11 is mounted as illustrated in FIG. 23. At this point the tap system of FIG. 23 and snap-fit connector 9 of FIG. 23 is operationally in the open position (both) as the movable central turret of the interlocking connector 9A of FIG. 23 has finished making the "Z" stroke, opening the passage of liquid. In this step, the tap + connector both are in the dispensing position and allow the liquid to exit the BIB through the tap and the connector itself, which is usually then connected to a dispensing machine.

[0028] However, these taps have some defects that the new inventive tap solves. The seals of these taps are not optimal and, after continuous connection for hours / days of the connectors (screw-on and / or quick-release) , as normally happens, they completely lose their sealing properties, generating liquid leaks. The leaks are due to the fact that the geometries that should facilitate the automatic closing of the tap (geometries "10.1" illustrated in FIG. 22, 23, 24, 25, 26, 27 and 27) , after a while remaining deformed under the push of the internal valve 11 (illustrated in FIG. 20, 21, 22, 23, 24, 25 and 26) which in turn is pushed by the connectors 7 or 9 of FIG. 26 and 23, lose their elastic capacity and no longer have the "strength" to push the valve 11 into the closed position, as illustrated in FIG. 21 and 24, thus causing liquid to leak from the application once the connector is removed (7 or 9 of FIG. 20 and 24) .

[0029] The flow of these taps is often limited, as can be easily noted in FIG. 23 and FIG. 26 where the known taps are illustrated in the open position of the tap + connector system since most of the channels that should facilitate the passage of liquid are "obstructed" by the geometries necessary for selfclosing and the shape of the channels themselves which necessarily have to withstand the thrust of the connector and counteract the opposing force given by the geometries 10.1 in the bending position as indicated in FIG. 23 (for the hook-on connector of FIG. 20) and in FIG. 26 (for the screw-on connector 7 of FIG. 24) . It can be immediately noted that the sealing and self-closing geometries, and the structures necessary for its support, of the tap "obstruct" the passage of liquids, significantly decreasing the flow from the system and also the structure necessary to support the deformation of the fins 10.1 when the screw-on connectors 7 of FIG. 24 and the interlocking 9 of FIG. 20 are in the "operational" position and push / deform the flexible fins 10.1 as illustrated in FIG. 23 and 26. It is necessary to find a solution that allows for a larger area for the liquid to pass through the tap 1.

[0030] There is a need to find an alternative solution to known configurations present on the market to allow the operational connection of the screw connector 7 of FIG. 8. Nowadays, known solutions have a thread on the upper part and one on the lower part, to facilitate the screwing and correct positioning of the screw connector 7 on the tap 1 as illustrated in FIG. 25 and FIG. 26. The creation of this thread (upper 12.6 of FIG. 25 and lower 12.7 of FIG. 25) is complicated during the mold manufacturing step (therefore much more expensive to make) , is difficult to control in terms of quality and also forces competitors to use more plastic material to create these geometries. Furthermore, these geometries generate on the plastic component, in its internal opposite wall 12.10 of FIG. 20, 21, 22, 23, 24, 25, 26 quality problems caused by deformations due to dimensional post-shrinkage which normally occur on injected plastic components leading to internal deformations in the molded piece which are very dangerous in terms of general seal (to liquids) of the system. Normally these postshrinkage deformations are more evident in areas where many geometries have been geometrically inserted to form an area of anomalously high and inconsistent thickness, as in the case of the upper geometries 12.6 in FIG. 25 and the lower geometries 12.7 in FIG. 25. The prerogative of this invention is finding an alternative solution (cheaper to produce than the known solution currently on the market) that allows obtaining the same current performances while improving the general quality of the plastic component on which they are obtained.

[0032] 2002 / 179875 disclose prior art delivering taps.

[0033] Object of the present invention is allowing the screwing of a screw connector in the simplest way possible by using projecting geometries 6.2, preferably flat, which protrude externally and be obtained on a supporting nozzle 6 which they deform once screwed onto the connector 7. To help the flexibility of the same, there are through-hole geometries 6.3 or non-through-hole geometries 6B .3 which enable this object. There also are chamfered geometries 6.14 which ensure that the sectors are given a proper "structure" to ensure that the connector 7 is screwed in a simple but safe manner.

[0034] Object of the present invention is also optimizing the internal areas obtained on the supporting nozzle 6 so as to have only two internal geometries (today on known taps there are multiple areas that make the production of the particular nozzle very complicated and difficult to produce) namely an internal ring geometry like the internal circular undercut 6.7 that is used when the screw connector 7 is used to keep the assembly IB still in position and a second projecting circular geometry 6.6 on which all the sealing geometries are obtained that allow the inventive tap 1, when it is in the final position of use (FIG. 4 and FIG. 5) to have an optimal seal against liquids by going into a sealing coupling with the external wall 3.8 of the internal body 3 (or the external wall 3.8B of the internal body 3B) . On the upper part of the second circular protruding geometry 6.6 there is a stop area 6.8, preferably flat, which is used when the tap is in the pre-assembly position by means of the simultaneous cooperation between the internal ring geometries 3.9-6.8 and the external ring geometries 2.1-6.1 and 2.4-6.1. Likewise, the flat stop area 6.8 is also used when the hook-on connector 9 is used, when it is operationally connected, as illustrated in FIG. 12, and acts as a stop for the descent of the internal valve 4 due to the cooperation of the stop area 6.8 with the preferably flat geometry 3.3 of the internal body 3.

[0035] Object of this invention is also creating an innovative, simple and eco-friendly tap that can be adapted to the connectors and filling lines currently on the market, without requiring modifications and without changing the actuation system, making it unique and universal for all connectors on the market, of both known types (quick- fit and screw-on) .

[0036] The present invention, moreover, shall solve the prior art problems by providing an improved dispensing tap that is made with a minimum number o f parts , using the least possible quantity of plastic, which is the main part of the tap, and that allows the tap opening operation to be performed without the use of metal springs or integrated spring flexible geometries 10 . 1 like those made on the tap of FIG . 20 , 21 , 22 , 23 , 24 , 25 , 26 which then lose their " spring ef fect" as happens today with the taps on the market , resulting in useless and not essential geometries for the correct use of the application, as well as a greater oxygen seal when the inventive tap 1 is still in the closed position and immediately after filling the BIB, due also to the use of high- tightness material and the shape of the sealing geometry, as well as preventing / reducing the oxidation of the liquid inside .

[0037] The inventive tap, being equipped with a high oxygen barrier, is suitable for aseptic applications , and therefore for aseptic treatments , which, at times , can be harmful and therefore inapplicable to some types of known taps , given that their dispenser must be subj ected to sterili zation cycles with hot steam, or gamma rays, or distilled water or other agents (even combined with each other) , which in some cases are aggressive, compromising the functioning of the closure.

[0038] A further object of the present invention is having the system that supports the pre-assembly external to the tap and operationally connected by exploiting an internal coupling geometry 2.1 on the cap 2 in coupling with an external ring geometry 6.1 obtained on the supporting nozzle 6, generating the stable, airtight and operational pre-assembly coupling 6.1-2.1 illustrated in FIG. 3.

[0072] With reference to the Figures , an exemplary and non-limiting embodiment of the dispensing tap 1 of the present invention is described . It will be evident to an expert in the art that the described tap can be made in equivalent shapes, dimensions and with equivalent details, and can be used for containers of various types, for example the so- called "Bag-in-Box" (BIB) ones, but also those of the rigid or semi-rigid type or others.

[0073] The tap 1 of the invention serves to dispense liquids from a container (not illustrated) , and substantially comprises: an elongated cylindrical support nozzle or main nozzle 6, equipped externally with connection and hook-up means 6.2, 6.4 and 6.5 (FIG. 17) with connectors 7 (FIG. 8 and 9) and external ring geometries 6.1 (FIG. 17) when the tap 1 is in the pre-assembly position (FIG. 3) . Inside there are also sealing means as second circular projecting geometries 6.6 (FIG. 17) and an internal ring geometry6.7 and a lower stop area 6.8 (FIG. 17) . Preferably, the connection means consist of sealing rings 6.4 and 6.5 (FIG. 17) and protruding geometries 6.2, 6.3, preferably from the sealing ring (FIG. 17) , which can be preferably, but not limited to, flat or even flat geometries with chamfered or curved connections, but extremely flexible, due to the central outlet geometry 6.3. Alternatively, but not limited to, a thinning of the section is obtained for the alternative version 6B.3, as relief geometry (FIG. 18) made to divide the flat geometry in two and facilitate the bending / deformation of the projecting geometries 6.2 and 6B .2 (FIG. 18) during the screwing step of the connector 7 (FIG. 8) and allowing the flat geometries to deform and "follow" the thread of the screw connector 7.2 (FIG. 8) , effectively creating a helical geometry guided by the actual thread present on the screw connector 7.2 (FIG. 9) facilitating its secure attachment for the connector 7 (FIG. 8) . A chamfered geometry 6.14 (FIG. 17) is present, useful for giving the right "structure" to both the sealing ring 6.5 and the projecting, preferably flat geometries 6.2. Preferably, the support nozzle 6 has internal blocking ring geometries 6.7 and sealing zones as second circular projecting geometries 6.6 inside it that are designed to cooperate with the geometries of the internal body 3 (FIG. 15) , effectively dividing the internal area of the supporting nozzle 6 into two zones and thus avoiding having to shape other coupling zones that are otherwise useful in the technology. Specifically and not in a limiting way, the internal ring geometry 6.7 cooperates with the coupling groove 3.1 of the internal body 3 (FIG. 15) when the tap 1 is in its final assembly position, as illustrated in FIG. 4. In particular, the cooperation between the internal ring geometry 6.7 of the supporting nozzle 6 with the external ring geometry 3.3 of the internal body 3 has its greatest effect when the screw connector 7 is used (FIG. 8) . As illustrated in FIG. 9, when the screw connector 7 is fully connected to the inventive tap 1, the coupling between the internal ring geometry 6.7 of the supporting nozzle 6 with the external ring geometry 3.3, 3.3B of the internal body 3 keeps the internal body 3 (and its assembly IB of FIG. 5) in the correct position, not allowing it to change its height which would compromise the opening of both the screw connector 7 and the inventive tap 1. The two ring geometries highlighted in FIG. 9 have the correct interference to keep the tap 1 + screw connector 7 system in the correct position for use. It should be remembered that, during the opening step (from the closed position 1 of FIG. 5 to the open position of 1 and 7 of FIG. 9 and FIG. 10 of the screw connector 7) , a minimum amount of force is generated on the geometries 6.7-3.3 / 3.3B which allows the interference 6.7-3.3 / 3.3B to keep the internal body 3 (IB of FIG. 5) in the correct position without problems. When instead the quick- fit connector 9 of FIG. 11 is used, as illustrated in FIG. 12, the applied force "FV" on the connector 9 allows to "overcome" the coupling interference 6.7-3.3 / 3.3B (therefore the interference between the internal ring geometry 6.7 with the geometry of the internal body 3.3, 3.3B) allowing, due to the manual push made by the operator on the interlocking connector 9, to move the central mobile part of the connector 9A and, consequently, to move and go into "operational sealing coupling", bringing the assembly IB of FIG. 5 to the opening position 9 and 1 of FIG. 12, "overcoming" the contrast given by the two internal ring geometries 6.7-3.3 and allowing their correct use. The movement of the internal valve 4 of FIG. 12 (IB of FIG. 5 on which all the other components are mounted to form an operational assembly) is also facilitated by the fact that the snap-on connector 9 has a greater opening stroke "Z" than the screw-on connector 7, as illustrated in FIG. 11. The movement of the valve assembly IB pushed by the connector 9 is "limited", in addition to the "Z" dimension of the connector 9 as illustrated in FIG. 11, also by the coupling of the circular geometry with a protrusion in its lower part, preferably flat, 3.3 with the flat stop area 6.8 obtained above the sealing area as second circular projecting geometries 6.6, as illustrated in FIG. 12 as 3.3- 6.8; an elongated internal cylindrical connecting body 3 (FIG. 15) . Referring to FIG. 15, different geometries can be seen internally. On the upper internal part of the internal body 3, a coupling groove 3.1 can be seen which mechanically couples with the cap 2 due to the mechanical cooperation between the groove 3.1 and an anchoring geometry 2.2, allowing the cap 2 itself to "drag" the assembly 1A (FIG. 13) , equipped with all the components mounted on the internal body 3, out of the tap assembly 1, when this is in the preassembly position, as illustrated in FIG. 3, to the filling position of the container, preferably but not limited to a BIB, as illustrated in FIG. 13, and also allowing the tap to be brought to the closed position at the end of the filling of the container itself, as illustrated in FIG. 4. The internal wall 3.11 (FIG. 14) allows for an internal sealing wall of the internal body 3 with the connectors available on the market (due to the hermetic interference with an O-ring (not illustrated) present on the central pin of the two connectors 7, 9 when they are in the position of use in FIG. 9, as regards the screw connector 7.6- 3.11, and in FIG. 12, as regards the snap-fit connector 9.6-3.11. Above the coupling groove 3.1, there are some hook teeth 3.2 which have the function, as on the known versions, of coupling with the snap-fit connector 9 (specifically 9.4- 3.2 of FIG. 12) , to allow the internal valve 4 to be closed (from the open position to the closed position) , which, once the snap-fit connector 9 has been removed from the tap 1, "drag", due to the cooperation of the teeth 3.2 with the hollow geometry 9.4, the assembly mounted on the internal body 3 (therefore the internal valve 4 of FIG. 16) is again in the upper release position, thus allowing the release of the connector 9. Continuing the description of the internal geometries, it is possible to note in FIG. 15, moving towards the lower internal part of the piece, the sealing seat (vertical internal circular rib) 3.15 of the internal body 3 (or 3.15B of the internal body 3B) , where the internal valve 4, when it is in the closed position before its first activation by means of one of the two connectors 7 or 9, rests on the external circular protruding sealing rib 4.6 on the internal vertical circular rib 3.15 of the internal body 3, generating a sealed coupling 3.15-4.6 highlighted in FIG. 3 and FIG. 4 in its two preassembly and complete assembly positions after filling. It is possible to note, inside the internal body 3, the tamper evident locking ring 3.14 (or 3.14B of the internal body 3B) , which allows the internal valve 4 to remain in the safety and closed position until the vertical push is operated by one of the two connectors 7, 9. This circular rib 3.14 interferes with the external protruding circular sealing rib 4.6 of the valve 4 and generates a safety that can only be violated after using one of the two connectors 7, 9 with the tamper evident coupling 3.14-4.6. Once having inserted one of the two connectors 7,

[0074] 9, the external circular projecting sealing rib 4.6 of the internal valve 4 surpasses the internal protruding circular rib 3.14 by elasticity and highlights the first opening that occurred as a tamper evident system. There is a second upper protruding circular rib 3.12 inside the internal body 3, which has the object of keeping the internal body in position 3 in cooperation with the external circular geometry 4.5 of the internal valve 4, as illustrated in FIG. 3, 4 and 5, with the coupling 3.14 - 4.5. Always inside the internal body 3, below the internal circular vertical rib 3.15, a whole structure develops with multiple arms 3.13 designed to shape, together with the a second central pin 3.18, the large liquid passage areas. It should be noted that this structure, with multiple arms 3.13 designed to shape, together with the second central pin 3.18, does not have any fundamental function with regard to the correct functioning of the application. It is even possible to remove it completely, as indicated in the version B illustrated in FIG. 27, 28 and 29 without altering any function of the application. In the version B illustrated in FIG. 27, 28 and 29, there is a further saving of plastic material, emphasizing the green aspect even more compared to the solutions present on the market. Furthermore, another positive aspect compared to the market is that version B is simpler to produce and therefore less expensive. Furthermore, the passage of liquid is increased to the maximum, placing it at the top, as regards the flow of liquid, in terms of performance compared to the solutions currently on the market. Returning to describe the first solution 3 of FIG. 15, it can be noted that, below the second central pin 3.18, there is the seat of the injection point which, being central, guarantees maximum efficiency and quality of filling of the plastic material during the injection step. Obviously, and not limited to, if it were decided to conform the inventive tap IB of FIG 27, 28 and 29 where version 3B of the internal valve of FIG 27, 28 and 29 is used, the injection point 3.18B is placed in a different position, as the entire central structure is no longer present, which instead in version 3 of FIG. 15 allowed the placement of the injection point 3.16 centrally. Moving externally on the internal body 3, it is possible to note a first external ring geometry 3.9 (or 3.9B) , preferably with a sharp edge at its end 3.3, useful to cooperate with the internal ring geometries 6.7 of the supporting nozzle 6 when the assembly 1A of FIG. 13 is in the final assembly position, as illustrated in FIG. 4, or when it is in the use position, as illustrated in FIG. 5. The tap assembly 1 illustrated in FIG. 5 remains in the correct position allowing the assembly mounted on the internal body 3 (together with the internal valve 4) to remain in the right position, mainly when the screw connector 7 is used, with the cooperation of the external ring geometries 3.3- 6.7 which have the right operating interference to keep the whole assembly in the right position, as illustrated in FIG. 9. There is a vertical wall of the external cylinder of the internal body 3 which cooperates and carries out a hermetic seal when it is in the open position (but also in the closed position as illustrated in FIG. 4 and FIG. 5 always due to the cooperation of the geometries 6.6-3.8) , as illustrated in FIG. 9 as regards the screw connector (cooperation of geometries 6.6- 3.8) , and cooperates and creates a hermetic seal when it is in the open position (but also in the closed position as illustrated in FIG. 4 and FIG. 5 always due to the cooperation of the geometries 6.6-3.8) as illustrated in FIG. 12. On the lower part 3.17 of the internal body 3 there is a further protruding geometry 3.16 which has two functions.

[0075] The first function, when the assembly 1A (FIG. 13) mounted on the internal body 3 is in the pre-assembly position, as illustrated in FIG. 2 and FIG. 3, keeps the assembly mounted on the internal body 3 in the pre-assembly position due to the support of the external ring geometry 3.9 on the flat stop area 6.8, but also, due to the cooperation of the external ring geometry 6.1 of the supporting nozzle 6 with the internal ring geometry 2.1 and the internal wall 2.4 of the cap 2, as illustrated in FIG. 3 where the operational geometric coupling 6.1-2.1 6.1-2.4 can be clearly seen. When instead it is in the final capping position (therefore the assembly 1A of FIG. 13 is completely inserted into the supporting nozzle 6 of FIG. 17) as illustrated in FIG. 4 and FIG. 5, the internal body 3, due to the ring geometry 3.4, 3.4B with a rounded tip 3.14, once having elastically bypassed the second circular projecting geometry 6.6 present on the supporting nozzle 6, is coupled operationally (6.6-3.4 of FIG. 4 and FIG. 5) and prevents the internal body 3 , on which the valve 4 is also mounted, from being removed . In practice , the cooperation of these two geometries 6 . 6-3 . 4 enables the natural creation of an anti-extraction system and another additional tamper evident system to protect the product contained inside , and consequently the final consumer ( the system does not allow the removal of the internal body assembly and therefore does not allow the container to be refilled, avoiding product counterfeiting, as well as a dispersion of plastic material into the environment and therefore ef fectively satis fies the new European and international directives on disposable plastic items , SUP , thus favoring their recovery and recycling) . Therefore , the inventive tap 1 must be designed to meet the requirements of the new European regulation called "Single-use plastics" ( SUP ) , as well as , for example , the AB 319 regulation of Cali fornia in the United States . Both regulations aim to increase the amount of plastic collected and recycled, thereby reducing marine litter . As a result , CPGs ( consumer packaged goods companies ) have called on their partners to develop solutions that not only comply with the new regulations , but also provide environmentally conscious consumers with solutions that fit their lifestyle and provide them with the best packaging experience. The inventive tap 1 fully meets these requirements;

[0076] - an internal valve 4 (FIG. 16) equipped with a circular external element 4.5 designed to operationally rest on the flat geometry 3.19 of the internal body 3 in order to limit the opening stroke of the valve pushed by the connectors (screw-on 7 in FIG. 8 and interlocking 9 in FIG. 11) allowing the valve to open the liquid passage and at the same time the connectors 7, 9 to remain open, due to a third central pin 4.7, preferably cylindrical, as illustrated in FIG. 9 for the screw-on connector with the operational couplings 4.7-7.5 and 4.5-3.19, and in FIG. 12 as regards the interlocking connector 9 with the operational couplings 4.7-7.5 and 4.5- 3.19. The outer ring 4.5 elastically passes the upper circular projecting rib 3.12 of the inner body 3, blocking any vertical exit movement with the operational coupling 3.14-4.5. There is a third central pin 4.7 which has the object of opening the connectors by moving their central cursors 7.5 of FIG. 8 for the screw-on connector 7, and 9.5 of FIG. 11 for the snap-on connector 9. There are ribs (one or more) 4.2 connected to the third central pin 4.7, which give structure to the valve and also allow the transfer of the downward movement imposed by the central pins of the connectors 7, 9 due to the coupling with the tip geometries 7.4 of FIG. 8 for the screw-on connector 7 and 9.3 of FIG. 11 for the snap-fit connector 9. The ribs allow for the creation of passage spaces 4.4 in the valve 4. Finally, there is an external circular projecting sealing rib 4.6 on the lower part 4.1 which has the function of ensuring an operational seal of the internal valve 4 on the internal body 3 due to the operational coupling 4.6-3.15 illustrated in FIG. 3 and 4. The external circular projecting sealing rib 4.6 also goes into operational coupling, when the tap is still closed and has not yet been "activated / opened" by any connector 7, 9 in its coupling 3.14-4.6, and guarantees the maintenance of the sealing position of the internal valve 4 until the intervention of one of the two connectors 7, 9 which overcomes the interference force 3.14-4.6 due to the connection of one of the two connectors and allows the definitive opening of the inventive tap 1; a protective cap 2 (FIG. 14) . This component has the task of protecting and covering the internal elements of the inventive tap 1 during all the production steps up to the final consumer, but also allows the filling machines to be provided with a docking area 2.3 (FIG. 14) which allows the assembly 1A (FIG. 13) to be removed from the pre-assembly position to the filling position, where it is free and ready to accommodate the filling nozzle of the filling machine (not shown) . There are preferably circular anchoring geometries 2.2 (FIG. 14) inside the internal body 3 with the coupling grooves 3.1 and the simultaneous external anchoring geometries 2.1 and the internal wall 2.4 on the external ring geometry 6.1 of the supporting nozzle 6, due to the coupling 6.1-2.1 and 6.1-2.4 of FIG. 3. Preferably, this latter operational coupling 6.1-2.1 allows the inventive tap assembly 1 of FIG. 3 to remain stably in the pre-assembly position without having further hollow or protruding geometries inside the support nozzle 6 (as occurs on the tap of FIG. 20, 21, 22, 23, 24, 25, 26 which had to obtain three different internal areas on the nozzle to support the different operating positions of the inventive tap 1, i.e. the pre-assembly position of FIG. 3, the complete assembly position after filling of FIG. 4, the dispensing position with the screw connector 7 of FIG. 9 and finally the use position with the interlocking connector 9 of FIG. 12. Finally, there is an internal wall 2.4 (FIG. 13) which seals with the external ring geometry 6.1 of the supporting nozzle 6 and, due to this interference, provides hermetic cooperation between the two components 6.1- 2.4 as illustrated in FIG. 3 (pre-assembly position) and FIG. 4 (final assembly position after filling) .

[0077] The tap 1 will now be described using the two connectors 7, 9 present on the market to demonstrate that the tap 1 adapts to existing connector systems without any problem, providing a new, green and "safer" technology in terms of performance compared to the technologies currently present on the market and available to consumers.

[0078] Generally, the inventive tap 1 placed, preferably on a BIB type container, is supplied to the end customer in a pre-assembly position, as illustrated in FIG. 3. This position then allows the end customer to place the BIB on the filling machine, which removes the assembly 1A as illustrated in FIG. 13 and temporarily releases the supporting nozzle 6, until the filling is complete. Subsequently, at the end of the BIB filling step, the filling machine stably and irremovably positions the assembly 1A of FIG. 13, placing it inside the spout in its final capping position, as illustrated in FIG. 4 and in this safety position, the container can be shipped to the end customers. Once the end customers arrive, the consumer removes and disposes of the upper protective cap 2 correctly and finds the inventive tap 1 ready to "welcome" all the connectors (screw- on 7 or snap-on 9) that are currently on the market for these applications. The opening and dispensing steps will now be described in detail for each type of connector.

[0079] Referring to FIG. 9, the operational connection between the screw connector 7 and the tap 1 can be seen. The screw connector 7, in order to be stably connected to the tap 1, exploits the opposite sectors 6.13, 6B.13 (preferably, but not in a limiting way flat) created on the outside of the supporting nozzle 6, with possible enabling geometries of the inclined plane 6.11 (FIG. 17 and FIG. 18) type and of the radius 6.12 / 6.12B (FIG. 17 and FIG. 18) type, or both at the same time, as generally illustrated on the (preferably flat) protrusion geometries 6.2 and flexible geometries 6B .2 of FIG. 18. These sectors have been shaped so as to be flexible and to allow them to adapt, during the screwing step of the connector 7, 9, to the helical profile of the thread present on the external connector 6.2 / 6.3-7.2. The two projecting geometries 6.2, preferably symmetrical but also asymmetrical, have a central relief 6.3 which facilitates bending and adaptation to the thread 7.2 of the connector 7, allowing a precise and safe coupling between the inventive tap 1 and the screw connector 7, as illustrated in FIG. 18, also compensating for the possible dimensional differences between one connector and another "normal" connector when dealing with plastic components. The central relief 6.3, by promoting the deformation of the two protruding sectors, preferably flat, allows the screw connector 7 to be screwed in a simpler and more precise manner, limiting the rotation and descent force of the same and therefore promoting a better experience of use for the end consumer compared to the solutions currently available on the market. Furthermore, the presence of a circular geometry with a chamfer 6.14 and 6B.14 provides the necessary "structure" to the two flat sectors used to bind stably to the screw connector 7, compensating for the loss of structure given by the central relief geometries 6.3 and 6B.3, as illustrated in FIG. 17 and FIG. 18. This particular compromise allows for obtaining of flexible but tenacious protruding relief geometries 6.2 and 6B.3, capable of replicating the complex threads of previous solutions on the market. Once the screw connector 7 is operationally connected, the central pin 7.5 of the screw connector 7 rests on the third central pin 4.7 of the internal valve 4, facilitating the opening of the supply channel of the connector 7.5. At the same time, the front part 7.4 rests on the nervature4.2 of the internal valve 4, moving it forward and facilitating the opening of the inventive tap 1. The central pin 7.6 of the screw connector 7 is in operational seal with the internal wall 3.11 of the internal body 3, ensuring the hermetic seal of the coupling, as illustrated in FIG. 9. The maintenance of the position of the assembly mounted on the internal body 3 is guaranteed by the internal ring geometries 3.3-6.7 while the liquid seal is guaranteed by the operational coupling of the protruding geometries 6.6-3.8. It should be emphasized that the inventive tap 1, when the screw connector 7 is used, does not move the internal body 3 forward, as instead happens with the push connector, changing its position during delivery ( as instead happens in the push connector as illustrated in FIG . 12 ) .

[0080] Once the tap 1 is opened, and therefore the internal valve 4 is moved to the open position, as illustrated in FIG . 9 , the tap 1 remains in the open position, always ensuring the final consumer has evidence of opening and therefore a tamper evident system as illustrated in FIG . 10 and in FIG . 29 for version B . The connector 7 , 9 is disconnected only when the container is empty . Once the connector 7 , 9 is disconnected, since the tap 1 is in the open position, it is impossible to counterfeit the product with a new filling of counterfeit product , thus ensuring additional protection for the final consumer .

[0081] As regards the second interlocking connector 9 , the procedure is similar but the internal movement of the tap 1 is di f ferent .

[0082] Referring to FIG . 11 , it is possible to see the commercially available snap-in connector 9 in the open position, not yet connected to any tap, while in FIG . 12 it is possible to see the snap-in connector 9 installed on the inventive tap 1 due to the mechanical cooperation of the protruding anchoring geometries 9 . 1 and 9 . 2 of the snap-in connector 9 with the sealing rings 6.5 and 6.4, preferably circular, of the supporting nozzle 6. The stable and safe operating connection 9.1-6.5 and 9.2-6.4 can be seen in FIG. 21. The end operator / customer, to activate the snap-in connector 9, and consequently the dispensing tap 1, must apply a manual force "FV" represented in FIG. 12. The "FV" force overcomes the position-holding force provided by the coupling 3.3-6.7, which allows the valve to be kept in position when using the screw-on connector as illustrated above, and allows the central pin of the connector 9 to enter the internal body 3 and perform the operational seal due to the coupling 3.11-9.6, as illustrated in FIG. 12, and to rest, at the same time, on the tip geometry 9.3 of the internal valve 4 and also on the internal body 3, allowing the internal body 3 to move forward, simultaneously with the opening of the inventive tap 1, since the push of the tip of the pin 9.3 of the connector 9 moves the internal valve 4 and allow its opening and the subsequent exit of liquid from the tap 1. At the same time, the connector 9 also opens its liquid passage channel due to the coupling between the third central pin 4.7 of the internal valve 4 and the tip of the internal sealing stem 9.5 of the connector 9, as illustrated in FIG. 12 (4.7- 9.5) . During this step just described and simultaneously with all the steps described above, the flexible teeth 3.2 of the internal body 3 bend, during the "descent" step of the internal body 3, guided to the "correct bending" due to the cooperation with the internal diameter 6.10 of the supporting nozzle 6, and are stably coupled with the hollow geometry present on the central pin 9.4 of the connector 9. Specifically, this mechanical coupling 9.4-3.2 allows the internal body 3 to return to the closed position, as illustrated in FIG. 21, as the mechanical coupling ensures that the internal body 3 is dragged back to the closed position. The flexible teeth 3.2, once they have exited the sealing diameter 6.10 of the supporting nozzle 6, are able to bend in the opposite manner and disengage from the central pin of the interlocking connector 9, as illustrated in FIG. 19.

[0083] It can also be noted the interference fit that generates the main seal and hermetic seal of the tap 6.6-3.8 of FIG. 12 and the fit that stops the descent of the internal body 3 in the correct opening position 3.3-6.8 of FIG. 12. As previously announced, the re-closing step follows an "opposite path" supported by the mechanical cooperation 9 . 4-

[0084] 3 .2 between the teeth 3 . 2 of the internal body 3 and the seat of the central pin of the connector 9 , which brings the tap 1 back to the closed position, as illustrated in FIG . 12 . Also in this case , once the tap 1 is opened, and therefore the internal valve 4 is moved to the open position, the tap 1 remains in the open position, as illustrated in FIG . 10 and in FIG . 29 as regards version B, because the internal valve 4 remains in the open position . This guarantees the end consumer evidence of opening and therefore a tamper evident system . The connector 7 , 9 is disconnected only when the container is empty . Once the connector 7 , 9 is disconnected, since the tap 1 is in the open position, it will be impossible to counterfeit the product with a new filling of nonoriginal product , thus guaranteeing the final consumer additional protection .
