DETAILED DESCRIPTION OF THE EMBODIMENTS
[0080] With reference to the Figures, an exemplary and non-limiting embodiment of the dispensing tap 1, 1A, and of the variants 1B and 1C adapted to the new universal body 4 of FIG. 30 is described (the variant 1C demonstrating the possible chance of using the body 4 of FIG. 30 also for the version currently on the market without problems, demonstrating its absolute universality).
[0081] It is evident to a skilled person in the art that the described tap can be made in shapes, sizes and with equivalent details, and can be used for containers of various types, for example those so-called Bag-in-Box, but also those rigid or semi-rigid containers and the like.
[0082] A first embodiment of the tap 1 of the invention is shown in FIG. 1, and uses a first body 4 of FIG. 30 and the new cap 2 of FIG. 33 with manual opening, as was and still occurs on the traditional tap 1A currently on the market, represented in FIG. 15.
[0083] A second embodiment of the tap 1B of the invention is represented in FIG. 36, and always uses the body 4 of FIG. 30 (which is universal for all versions) which is coupled with the new cap 2B of FIG. 39, both with useful geometries for obtaining the joint between the two components, which both serve for dispensing, as already mentioned in document WO2021/111480 by the same Applicant, changing only the connection method between second cap 2 and 2B and body 4 of FIG. 30.
[0084] Furthermore, the version of the tap 1C of FIG. 43 is also shown here in order to demonstrate that the universal body 4 of FIG. 30 has no problem in adapting also to the cap 2A of FIG. 28 which is currently on the market. Obviously, the standard configuration on the market of the cap 2A of FIG. 28 is shown here, which uses the ultrasonic welding technology to connect stably to the body 4 of FIG. 30: however, it is possible to create the same coupling geometries present on the cap 2 of FIG. 33 and the cap 2B of FIG. 39 to create those coupling geometries useful for exploiting the two front and rear slots 4.1 of FIG. 30 in order to create a coupling between the two cap and body components 4 of FIG. 30.
[0085] Obviously, this third solution 1C of FIG. 44 is shown only to confirm the universality of the body 4 of FIG. 30, but it will not be taken into consideration because, even if it is understood that the dispenser tap 1C would work optimally, it would not be able to meet the new European and international directives on disposable plastic items (SUP), as the tamper-evident band, unlike the other versions 1 and 1B, is removable and therefore disperses into the environment.
[0086] Considering instead the versions 1 (FIGS. 1) and 1B (FIG. 36), they comply with the new European and international directives on disposable plastic items (SUP), and in both versions they also use the new driving wings 3 of FIG. 32 with the 3.1 opening planes integrated on each flap (this allows modifying the current operating element as it will be easy and economical to add the two planes 3.1 of FIG. 32 on each flap) and the internal valve or elastic dome membrane 5 of FIG. 31 equal to that used today on the tap 1C on the market shown in FIG. 15. The fact of being able to reuse the components currently produced (or in any case reuse them with a small modification, as in the case of the operating element with the addition of wedges) gives further value to the present invention, as it saves time and money and does not change the final perception of the customer, as the new geometries are hidden.
[0087] The new inventive solution of the tap 1 of FIG. 1 will now be analyzed, which has a new seal/cap 2 that can be opened manually, and which has such a geometry that it can be compared aesthetically and also functionally to the seal/cap of the tap 1A currently on the market in FIG. 15.
[0088] This inventive seal 2 of FIG. 1 allows manually freeing the fins 3, allowing their movement and therefore the opening and delivery of fluid from the tap itself, all this while keeping the seal 2 bound to the inventive tap 1 as shown in FIG. 12.
[0089] As can be immediately noticed, unlike the known model 1B of FIG. 23, which has an automatic opening of the lateral tamper-evident flaps, this new cap 2 has a tamper-evident flap 2.1 with manual front opening (FIG. 1) and is firmly bound to the main body, avoiding its loss into the environment, due to the flexible hinges 2.2 of FIG. 1.
[0090] The new version of cap 2, body 4 and element 3 of FIG. 1 will now be analyzed, leaving out only at the end the analysis that explains how to adapt the new coupling geometries of the tap 1B of FIG. 36 to the new geometry of body 4 of FIG. 30.
[0091] With reference to FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 32 and 33, the tap 1 of the present invention is provided with a configuration which substantially comprises: [0092] a body 4 (FIG. 30), which is a body with a traditional geometry equal to that used today for the tap 1A currently on the market, on which the necessary geometries were then obtained to make it compatible with the new caps 2 (and consequently also with the cap 2B) which will soon come on the market, making it universal: this provides a huge advantage in terms of cost and time of realization of the entire project, as it allows the use of components and equipment to produce the existing taps 1A to make the inventive tap 1 highlighting its green side even more. This body 4 is equipped with an elongated end 4 BACK formed by a cylinder 4.3, preferably placed perpendicular to the front cylinder 4.2 of FIG. 30, identifiable in the area 4 FRONT. The necessary geometries are obtained on the elongated part 4.3 of FIG. 30 in order to obtain, due to the interference between the surfaces of the components concerned (in this case the body 4 and the connection nozzle with the container, not shown), the element connection (and liquid seal) 4.6 on the connection nozzle with the container (not shown), and the anti-removal (anti-counterfeiting) element 4.5 connecting with the container (not shown), preferably but not limited to the BIB. Between the 4 Front part and the 4 Back part, there is a disc 4.11 of FIG. 30 useful for bag production machines (not shown) and for filling machines (not shown) to have a gripping area (if the cap is being removed to fill the bag: fluid filling phase of the bags on the filler) and/or pushing machines (if you are filling the bag full of fluid or if you are positioning the tap on the bag just produced but still to be filled in the pre-assembly position: pre-assembly phase in the removable position in the bag manufacturing phase) of the tap. Frontally, in the part 4 FRONT of FIG. 30 there is a cylinder 4.2, inside which the internal sealing wall 4.4 and the internal sealing area 4.7 of FIG. 30 are obtained, useful for going into sealing coupling (5.1-4.4) and (5.3-4.7) with the membrane 5 of FIG. 31, which are coupled with the sealing circumference 5.1 and the vertical sealing wall 5.3 of the internal valve or elastic dome membrane 5 of FIG. 31. The seats are also obtained on the front cylinder 4.8 which act as a guide for the sliding and seat of the driving projection 3.4 of FIG. 32. The front and rear slots 4.1 of the front cylinder 4 FRONT are obtained on this body 4 of FIG. 30, in order to create the coupling seats of the teeth obtained inside the cap 2, due to the geometries 2.5 of FIG. 33 (and also of the cap 2B). The body 4 of FIG. 30 can also be used for the traditional methods of connection with the second cap 2A of FIG. 28, namely ultrasonic welding and laser welding, thus underlining its extreme ductility to adapt to any version of the cap. While the compact body version 4 is shown here, it is obviously easy to bring the same geometries also to the traditional body 4A of FIG. 29; [0093] an internal valve or elastic dome membrane 5 of FIG. 31 (in common for all versions) comprising a coupling area 5.4 inside the component, as shown in FIG. 31, a sealing cavity 5.1 and a vertical sealing wall 5.3, which are operatively coupled, sealing the fluids with the internal geometries of the body 4. The special dome geometry and the material used allow the particular internal valve or elastic dome membrane 5 of FIG. 31 to be elastic, and give to the tap assembly 1, 1B the particular self-closing characteristic of the valve 5, once the external mechanical force applied by the user to the external fins of the operating element 3 of FIG. 32 has been eliminated; [0094] a driving element 3 of FIG. 32 which has the particularity of maintaining all characteristics of the first element 3A used today for the tap in production, but with the addition (and therefore only a simple modification that will allow the component to adapt to the new tap configuration 1 of FIGS. 1 and 1B of FIG. 36 by modifying the current production molds) of two planes 3.1 of FIG. 32 on the upper part of the external fins, which allow for the tap version 1 of FIG. 1 to have a flat contrast between the seal 2.3 of FIG. 33 and the plane 3.1 of FIG. 32, which, when the seal 2 is closed, prevent the opening of the tap 1 of FIG. 4 and, for the version 1B of FIG. 36, instead guide the flaps/flaps 2B.1 obtained on the second cap 2B (FIG. 36), allowing the automatic opening (and at the same time the breaking of the guarantee seal) of the tap 1B of FIG. 36. There are also hooking geometries 3.2 at the ends, useful for fasten to the valve 5 by means of the coupling geometry 5.4 of FIG. 31 and to the external fins 3.3 of FIG. 32, useful for guaranteeing finger gripping areas in order to allow the tap to open, as shown in FIG. 35. There are also guide and sliding geometries 3.5 in coupling with the geometries 4.8 of the body 4 of FIG. 30; [0095] a cap 2 (better shown in FIG. 33), with movable seal 2.1 of FIG. 33 with automatic opening stably bound to the fixed main body 2.13 due to the hinges 2.2 of FIG. 33 and the jumpers/teeth 2.8 of FIG. 33, forming a single component indivisible, as required by the new European and international directive on single-use plastic articles (SUP). The cap 2 is provided with an internal system with hooking teeth 2.5, which are then stably coupled to the two hollow geometries 4.1 of FIG. 30 obtained on the main universal body 4. The two hooking teeth 2.5 of FIG. 33 have been obtained on the two internal fins 2.10 of FIG. 33, which have the purpose of keeping the membrane 5 of FIG. 31 in the correct position inside the body 4 of FIG. 30 once assembled, due to the cooperation of the plane 5.5 of FIG. 31 with the plane of the fins 2.11 of FIG. 33. The fins 2.10 of FIG. 33 of the new cap also have inside them two tracks 2.7 (a front pair and a rear pair) which guide the driving element 3 of FIG. 32 due to the cooperation of the protruding geometries 3.4 of FIG. 32 and the sliding rails 2.7 of FIG. 33. The front outer part of the cap 2 of FIG. 33 has a gripping tab 2.12. The front part of the seal 2.1 is bound to the main central part 2.13 of the cap 2 due to the two side hinges 2.2, which have the purpose of binding the seal 2.1 to the main body 2.13, preventing it from being dispersed into the environment, as required by the new directives and complies with the new European and international directives on disposable plastic items (SUP), and thus ensuring that it remains bound to tap 1 after opening and does not disperse into the environment, or is disposed of incorrectly, allowing for proper recycling. In addition, the hinges 2.2 allow the opening of the seal, as shown on FIGS. 9, 10, 11, 12, 13 and 14, and therefore in practice they are the flexible and anchoring element of the movable part of the new guarantee seal. The integrated seal system remains anchored to the second cap 2 of FIG. 33, which in turn is stably bound to the first body 4. Referring to FIG. 33, it is possible to highlight the characteristics of the new cap 2 with the tamper-evident teeth 2.8 which they give evidence of breakage of the seal 2.1 to the final customer, and act as a guarantee seal when the tap 1 is still closed and sealed, before the first opening. The movable part that overturns at 270, as shown in FIG. 15, once the tap 1 is completely open, has two stiffening ribs 2.14 inside it, which also have the purpose of supporting the front geometry, resting on the front cylinder 4.4 of FIG. 30 of the body 4 during storage, preventing the movable tilting part of the seal 2.1 from deforming, compromising its function. Inside, the movable part of the seal 2.1 will have an anchoring tooth 2.9 which hooks firmly to the tooth 2.4 of FIG. 33, blocking its overturning and giving further evidence of the first opening, as shown in FIG. 15. Elements can also be obtained thin connecting jumpers 2.8, which bind the movable front flap of the cap 2 to the main body 2.13. These connecting jumpers 2.8 break upon first opening, due to the thrust of the front seal 2.1 which can be moved during the overturning operation, and guarantee immediate visual feedback for the end customer (together with the final state of the tap in which you can also see the seal 2.1 anchored by means of the hooks 2.4-2.9, as shown in FIG. 15) which understands that the tap 1 has already been opened, avoiding dangerous counterfeits for the final consumer.
[0096] The cap 2B, in the version to be used with the universal body 4 of FIG. 30, is shaped like the cap 2 of FIG. 33, in order to be able to adapt to the new anchoring geometries of the universal body 4, while maintaining all its operating characteristics. With reference to FIG. 39, there is therefore a toothed interlocking system 2B.5 between the second body 4 and the cap 2B, and it is obtained like the cap 2 of FIG. 33 on the two internal fins 2B.10. The teeth 2B.5 fit into the seats/slots/holes 4.1 of the universal body 4.
[0097] The preferred embodiments of the invention have been described, i.e. mainly the interlocking versions, but this does not limit the operational scope of the present invention, as this invention can be extended, with the relative modifications, also to the versions which exploit the existing welding technologies between two components (as shown for example, and for information only, in FIG. 47, where the universal main body 4 is welded to the cap 2A currently produced, due to ultrasonic welding technology). In this case, the new versions of cap 2 and 2B, appropriately modified, can also be used, even with the currently used welding technology between the two components and therefore not with the joint.
[0098] In summary, a new inventive solution has been described, which provides for the use of the new cap 2 of FIG. 33 with a guarantee seal bound to manual opening with a flap system and hooking on the rear geometry present on the cap itself, unlike the known cap, which provides for the use of a cap with a binding guarantee seal with automatic opening).
[0099] As shown in FIG. 5, the inventive new faucet consists of four components. A main body 4, on which the geometries necessary for anchoring the cap 2 and the sealing geometries 4.6 to the fluids on the back and anti-counterfeiting locking 4.5 are created, which are coupled with the relative sealing and locking geometries present on the nozzle present on the Bags of the BIB system (not shown) and internally, referring to FIG. 6, on the front cylinder 4.4, the sealing geometries 4.2 and 4.7 which are hermetically coupled with the sealing geometries (static 4.2 and dynamic 4.7) present on membrane 5 in points 5.1 and 5.3. Firmly bound due to the coupling 3.2 of FIG. 6 on the geometry 5.4, there is the operating element 3 which has the function of allowing the opening of the flexible dome valve 5 due to the action of the end user, as shown in FIG. 36. The operating element also has the important function of cooperating with the geometries 2.3 of FIG. 6 (which go against the surface 3.1 obtained on the operating element 3) and avoiding accidental opening of the tap 1 of FIG. 1 when the cap seal 2 is still untouched. Finally, the cap 2 of FIG. 6 is stably and immovably bound to the body 4 due to the simultaneous cooperation (interlocking) of the geometries 2.5, which are stably anchored in the slots 4.1 of the body 4, creating a complete and non-complete tap assembly 1 of FIG. 1, which is more divisible, as required by the new Single Use Plastics (SUP) regulations, and, for example, California AB 319 regulation in the United States. Both regulations aim to increase the amount of plastic collected and recycled, thereby reducing marine litter.
[0100] Referring to FIG. 1, it is possible to see the tap with the new seal/cap 2 in its closed position and with the guarantee seal intact. The teeth 2.8 are intact, the tip-up seal part is in its closed position and keeps the tabs 3 stationary in its closed position due to the action of the two planes 3.1 obtained on the operating element 3 with the geometry 2.3 obtained on the cap 2.
[0101] Referring to FIGS. 9, 10, 11, it is possible to see the guarantee seal at the beginning of its opening phase (controlled by the action that the user performs on the movable part of the seal 2.1 of FIG. 9 and by inducing the movable part of the seal to perform a rotation that has the hinge in the area of the two flexible hinges 2.2 of FIG. 9 and allows at first to break the connecting teeth between the movable part of the seal 2.1 of FIG. 33 and the fixed one 2.13 of FIG. 33. It can also be noted that the two geometries 3.1 and 2.3 that hold the driving element 3 still, with reference to FIG. 9, have detached even if they are not yet completely released. At this stage, it is not yet possible easily dispense liquid. The seal opening phase continues on FIGS. 12, 13, 14: in this case, the overturning of the movable part of the seal by 270 is completed due to the manual action of the end user and the same movable part of the seal 2.1 goes to firmly bond, due to the hooking tooth obtained on the mobile part 2.9 of FIG. 33, to the tooth 2.4 created at the rear, again on the cap 2 of FIG. 33. In this case, the tap 1 is in the position of complete opening and fixing, and allows the free movement of the operating element 3 and the consequent possibility for the final user to dispense the liquid, preferably but not limitedly by the BIB systems. In addition, the tap in the fully open position shown in FIGS. 12, 13, 14 is further evidence of opening for the customer (in this way it is also an additional anti-counterfeiting system and highlights the first opening of the customer).
[0102] The movable seal 2.1 in FIG. 33 will thus be bound to tap 1 and will not be dispersed into the environment, as required by the new directives in terms of recycling.
[0103] The great advantage is that it does not require a change in the habit of opening and using the application compared to the solution 1A currently on the market in FIG. 15, and therefore it will be much easier to put it on the market and get it to be accepted by end consumers. Furthermore, the aesthetic shape of the new hood unequivocally recalls the one currently on the market, not creating confusion in the final customer.
[0104] Furthermore, the manual opening system will remain operational, as in the present technology on the market, only in this case there is the enormous advantage of complying with the new Disposable Plastic regulations (SUP) and, for example, the California AB 319 Regulation in the United States. Both regulations have the objective of increasing the amount of plastic collected and recycled, consequently reducing marine litter, which cannot happen with the current technology 1A of FIG. 15 which provides for the removal of the tamper-evident band.
[0105] Taking into consideration FIGS. 36 to 42, the self-opening cap 2B is shown, adapted to the new geometry of the universal body 4. The anchoring teeth 2B.5 are made on the internal fins 2.10 and are then operationally coupled with the body 4 of FIG. 30 as shown in FIG. 39. Inside the two fins 2B.10 of FIG. 42 there are the track geometries 2B.7, which guide the sliding of the operating element 3 of FIG. 32 in coupling with the rear and front guides 3.4. The plane 3.1 obtained on the driving element 3 enables the automatic opening of the flaps of the guarantee seal of the cap 2B (2B.1) sliding on the flat surface.
[0106] According to the invention, therefore, a liquid dispensing tap 1, 1B, 1C is provided substantially comprising: [0107] a containment body 4; [0108] an internal valve or elastic dome membrane 5 contained within the body 4; [0109] a driving element 3 partially contained within the body 4 and operatively coupled to the internal valve or membrane 5 to enable/disable a supply of liquid from the tap 1, 1B, 1C; and [0110] a cap 2 placed above the body 4 to cover the tap 1, 1B, 1C, the cap 2 being composed of a fixed main body 2.13 equipped with a movable seal 2.1 with automatic opening stably bound to the fixed main body 2.13 due to hinges 2.2 and jumpers 2.8.
