Description

[0001] DISPENSING TAP EQUIPPED WITH ANTI -COUNTERFEITING AND

[0002] PROTECTING SYSTEMS FOR STERILIZATION CYCLES WITH

[0003] SUPERHEATED STEAM UNDER PRESSURE

[0004] The present invention relates to a tap for dispensing liquids from containers , in particular containers of the so-called "Bag- In-Box" (hereinafter referred to as BIB ) type , mainly but not limited to being able to hermetically seal a container, preferably BIB, which before , and sometimes also after, filling are subj ected to sterili zation processes with superheated steam delivered under pressure or a chemical sterili zation also delivered under pressure .

[0005] The use of BIB containers for shipping and distributing liquid food products , preferably but not limited to dairy and liquid egg, has increased signi ficantly in recent years . One of the most common procedures when filling flexible containers , preferably but not limited to BIB, with (preferably but not limited to ) food products that are sensitive to micro-bacteriological contamination ( such as the dairy and liquid egg market) is pressurized superheated steam sterilization or pressurized chemical sterilization. These procedures minimize potential contamination and maximize the shelf life of the products inside the containers. While sterilization of containers for high acid products is easily achieved due to the inherent characteristics of the liquids themselves which are acidic, there have been serious problems associated with low acid applications. This is because high acid products have an inherent advantage, that is, microbes and microorganisms have difficulty surviving and reproducing in highly acidic materials. The same is not true for low acid materials. In particular, microbes and microorganisms can thrive in a low-acid environment. For this reason, sterilization procedures for containers used in low-acid environments are substantially more stringent than those for high- acid environments. In a low-acid filling process, for example, before but sometimes also after filling, the tap assembly is exposed to superheated steam for a predetermined period of time. It can be appreciated that if chemicals (chemical sterili zation) are added for sterili zation obj ects , the required steam temperatures may be lower .

[0006] Providing an inventive tap that can withstand sterili zation treatments has proven to be very dif ficult . These sterili zation treatments have been shown to be highly destructive for taps . And so sometimes the end result is that , after the sterili zation treatment (with superheated steam or chemical ) , the material contained inside the flexible container, preferably BIB, is compromised, as the taps lose their hermetic protection properties for the product contained inside the container : therefore , a microbiological contamination occurs that requires the entire packaging to be discarded with the deteriorated content inside , causing serious economic damage , but above all a potential damage to the health of the consumer . Since , as mentioned, the sterili zation process is highly destructive for dispensing caps , the accessories necessary for dispensing the product are often supplied separately, which are fixed on the dispensing cap by the end customer and which will be described later .

[0007] There are known in the prior art some tap configurations that use technology consisting of self-closing and self-sealing silicone valves for liquids .

[0008] Currently, there are four manufacturers of closures on the market that contain flexible silicone valves:

[0009] 1. SCHOOL IPN: W02010 / 047814

[0010] 2. RAPAK: WO2016051276

[0011] 3. VITOP MOULDING (the Applicant)

[0012] 4. LIQUI-BOX: WO2013033135.

[0013] Specifically, the Applicant has filed these three patents relating to ideal closures, also for use in the dairy and liquid egg sector, which use, preferably but not limited to, flexible valves, preferably in silicone, inside them, namely:

[0014] 1. WO2019111285A1;

[0015] 2. W 02023058072 A 1 ;

[0016] 3. WO2013175515A1.

[0017] The three patents listed above specifically study systems equipped with valves made of flexible material, preferably silicone, which have the main function of being able to close automatically once disconnected from the dispensers or devices currently on the market.

[0018] The Applicant has also already filed in the past (WO2013175515A1 ) a very valid technical solution that allows obtaining special closures to be able to supply the market without any problem : this solution involves the extreme treatment of pressuri zed steam ( or chemical ) under pressure , i . e . the market that concerns dairy products and liquid eggs , without necessarily having to use a silicone valve inside it, but rather using a frangible membrane system that is "broken" due to the insertion of a special device in the cap .

[0019] However, the dairy and liquid egg market requires "one way" systems that can be connected in a stable and immovable manner, so that crosscontamination cannot occur between one BIB and another .

[0020] The solutions above allow removing and reusing the dispenser accessory which, however, i f not cleaned and steri li zed properly, could be a vehicle for cross-contamination between the new BIB still to be used and the old BIB j ust finished .

[0021] The market requirement requires having taps that do not need to be disconnected once activated, and therefore the market request is to have an innovative cap, and an accessory for the distribution of the liquid, that once connected will be irremediably immovable from each other, thus allowing to " eliminate" from the inventive cap device the flexible and sel f-closing component formed by the internal valve , preferably in silicone , which therefore becomes superfluous for the correct functioning of the application : this allows signi ficantly reducing the cost of the inventive tap, as it is possible to eliminate from the final configuration the expensive flexible valve , preferably in silicone , inside it .

[0022] The market requires the possibility of having a definitive , immovable connection with external dispensing "accessories" (which, as will be described below, can be actual dispensing taps or simple "tube" connectors ) in order to create a "disposable" hygiene system .

[0023] A prerogative of this invention is therefore creating a tap that is completely made of plastic material ( and therefore easily recyclable ) , that resists steam and / or chemical sterili zation cycles , and that adapts to the various systems ( dispensers ) currently on the market , ef fectively replacing the old tap versions currently on the market .

[0024] Another prerogative of the present invention is creating a single version of the dispensing tap and accessory in order to optimize the number of versions produced to cover the world market.

[0025] Currently, the systems on the market are expensive and complicated: to meet the needs of the market, different versions are required, so the tap of the present invention has as its primary objective that of creating a simplified system and therefore more attractive to the market, since the total cost of the inventive tap and the systems associated with it to allow its dispensing is significantly lower, managing to reach the targets required by the market itself and limiting the number of versions on the market. In this way, the invention provides a product that guarantees greater protection of the product, both in terms of sealing and dispensing associated with the tap itself, and in terms of anticounterfeiting of the product, which is a very important issue nowadays.

[0026] In addition, a dispensing tap is expected to comply and meet the requirements of the new European regulation called "Single-use plastics" (SUP) , adopted by the European Parliament on March 27, 2024, as well as, for example, the AB 319 California regulation in the United States. Both regulations aim to increase the amount of plastic collected and recycled, thereby reducing marine litter . Therefore , 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 li festyle and provide them with the best packaging experience .

[0027] Documents US-A-3 474 933 , AU-A-20779 76 , US-B2- 9 604 836 e WO-A1-2019 / 111285 disclose delivering taps according to the preamble of Claims 1 and 2 .

[0028] An obj ect of the present invention is therefore providing a tap as described above which achieves a perfect liquid seal and is aseptic-test proof , ensuring a perfect seal when the tap is in the closed and / or transported position, and until the top cap is removed due to the use of di f ferent materials and correct component geometries .

[0029] Another obj ect is providing a tap that has tamper-evident and anti-counterfeiting system that show the removal of the top cap, due to the cooperation of geometries once the tap has been assembled .

[0030] An additional obj ect is creating a regulator where the back is shaped in order to minimi ze the amount of oxygen entering the bag ( in case of using a BIB container ) .

[0031] Another obj ect is providing a tap as disclosed above which is equipped with a warranty seal of the tamper-evident type . When the tap is assembled, the top cap anchors to the main body and creates a tamper-evident sealing system, which irreversibly highlights its opening once opened .

[0032] The inventive tap, being equipped with a high oxygen barrier, is suitable for aseptic applications .

[0033] A further obj ect of the present invention is creating parts that are easy to produce during the molding step and easy to assemble in order to reduce production costs to a minimum .

[0034] A further obj ect is creating an inventive tap with flexible means of anchoring the accessories in an immovable manner .

[0035] A further obj ect is creating accessories necessary for the dispensing of liquids contained, preferably but not limited to , inside the BIB, which anchor themselves in a stable and definitive way to the inventive tap .

[0036] The obj ect of this invention is also creating a tap that resists steam and / or chemical sterili zation cycles , and that optimi zes the number of versions on the market with a single version, effectively covering the entire range of use and optimi zing production costs and above all the final sales price to the customer . Furthermore , it has to provide a new user experience ( easier to operate than the competition) with anti-extraction and tamper-evident sealing systems that give greater guarantee of healthiness to the end customer and allow him to recogni ze counterfeit products . Furthermore , the new inventive tap, and the related " accessories" to activate it , are completely made of plastic, thus favoring its collection and recycling .

[0037] The above and other obj ects and advantages of the invention, as will result from the following description, are achieved with a dispensing tap such as that described in claim 1 . Pre ferred embodiments and non-trivial variants of the present invention form the obj ect of the dependent claims .

[0038] The present invention will be better described by some preferred embodiments , provided by way of example and not of limitation, with reference to the attached drawings , in which :

[0051] - Figure 15 is a top, side , sectional view of the safety seal cap of tap 1 .

[0052] An embodiment of the tap 1 according to the invention will be described below, as well as its associated accessories , namely the universal dispensing tap 2 and the delivering probe 3 , which are immovable once inserted into the tap 1 , making the application safe and hygienic for the final consumer and compliant with the new European regulation called " Single Use Plastics " ( SUP ) .

[0053] This inventive tap can be considered as a "oneway" evolution speci fic for high temperature ( and / or chemical ) and pressuri zed filling of the known taps of the same Applicant , disclosed in patents WO2019111285A1 and W02023058072A1 . The prerogative of these two patents was to create closures that adapt to the probes present on the market , allowing the connection and disconnection of the same . The exact opposite of what happens for the dispensing tap 1 of the present invention .

[0054] In summary, the embodiment of the tap 1 for dispensing liquids according to the invention will be described, resulting from the coupling of a main body 4 , shown in Figure 14 , to be coupled, preferably by interlocking, with an upper cap 5 which also acts as a tamper-evident seal , shown in Figure 15 . Preferably, but not limited to , such seal is a rupture membrane 6 welded to the main body 4 or created in one piece by inj ection molding and integrated into the upper tamper evident cap 5 .

[0055] It will be evident to a person skilled in the art that the tap 1 described may be made in equivalent shapes , dimensions and with equivalent details , and may be used for containers of various types , for example the so-called " Bag -in-Box" ones , but also those of the rigid or semi-rigid type or others .

[0056] The tap 1 of the invention serves to protect the liquid contained preferably inside the chosen container, and allows the dispensing of the same when the liquid dispensing accessories are coupled, in a stable and irremovable manner, from a container by means of the operational insertion of a universal dispensing tap 2 or a delivering probe 3.

[0057] This tap 1 substantially comprises a main body 4 (better illustrated in Figure 14) provided, starting from the center, with a circular communication channel, preferably but not limited to central, with a circular surface 4.1 to enable the connection of the universal tap 2 or the delivering probe 3, and an internal circular surface for operational sealing 4.4. Moving towards the outside of the component, there is a flexible shaped geometry 4.9 which has the specific task of compensating for any deformations transmitted by the connected accessories (delivering probes 3 and universal dispensing tap 2) to the external dispensing cylinder 4.8. The external surface 4.8 serves, once the tap 1 is operationally coupled with a nozzle present on the container, to guarantee a perfect seal for the liquids of the container itself, preferably BIB. Continuing to describe the lower area of the body 4 of the inventive tap 1, it is possible to note concentric protruding ring-shaped geometries 4.7 which serve to operationally hook up to the nozzle present on the container. There is a protruding ring 4.6 external to the piece, which allows the manipulation of the inventive tap 1 on the machines that the application encounters in its production cycle, when it has to be placed or manipulated to fill the container itself. The projecting ring 4.6 is interrupted, preferably but not limited to, in two points 4.10 preferably symmetrical, so as to create two "free" areas useful for facilitating the grip with the fingers and the opening of the upper tamper evident cap 5. On the upper part of the main body 4, there is an undercut geometry 4.5 which serves to stably attach the upper tamper evident cap 5.

[0058] The tap 1 also includes a protecting tamper evident cap 5 (illustrated in detail in Figure 15) which has the main, non-limiting object of protecting the rest of the inventive tap 1 during the hot steam (or chemical) sterilization steps under pressure and, when this critical step of the process is finished and distribution to external customers begins, of protecting the conformity of the product from external contamination up to the final customer and above all to give evidence of any opening and / or counterfeiting of the product, due to particular geometries. With reference to Figure 15, in the upper tamper evident cap 5 it is possible to see a protruding circular geometry 5.1, preferably concentric, which has the object of coupling stably with the throat 4.5 of the main body 4, and of guaranteeing the perfect seal to liquids as well as external contamination. Internally, there is a conical geometry 5.3 placed below the circular projecting geometry 5.1 and designed to cooperate with an internal weight-discharging geometry 5.7 to provide the necessary flexibility to the upper tamper evident cap 5. There is an internal geometry 5.4, preferably flat, which seals the application even better when it is in the closed position, as illustrated in Figures 4 and 5, coupling with the plane 4.11 obtained on the main body 4. Externally, on the upper part of the upper tamper evident cap 5, there are two semicircular connecting sectors 5.6 of the straps 5.2, which in turn are connected by one or more breaking bridges 5.5, which have the object and function of breaking to allow the straps 5.2 to bend, maintaining the straps 5.2 as the rotation fulcrum for each of the two, and thus giving evidence of the first opening. The straps 5.2 bend and allow the end user to have one or more grip areas to remove the tamper evident cap 5 from the main body 4 , and free the tap 1 from its protective cover, and allow the insertion of one of the two accessories (universal dispensing tap 2 or delivering probe 3 ) .

[0059] A sealing guarantee membrane 6 of the tap 1 is illustrated in Figure 6 . In the main version of the tap 1 , this component is preferably welded to the main body 4 . When the universal dispensing tap 2 and the delivering probe 3 are inserted, these , due to the tip present , perforate the welded membrane 6 and allow the dispensing of the fluid contained inside the container .

[0060] With particular reference to Figures 2 and 16 , the first accessory required for dispensing is illustrated, the universal dispensing tap 2 . This tap is an evolution of the perforator cap described in document W02006085347A1 . This dispensing tap 2 remains substantially unchanged in terms of general functionality . All the geometries necessary for its correct positioning in the tap 1 have been obtained in order to generate a stable , safe assembly for the best protection of the customer, and which is immovable once inserted in tap 1 . In order to optimi ze the quantity of dispensing taps to be placed on the market , the dispensing tap has been shaped in a single solution on which, due to the immediate change of only a small part of the mould, different versions are created just by varying the size of the holes AO and BO (Figures 16 and 17) which are located on the pointed end. In the taps on the market, it has instead been necessary to introduce at least two types of dispensing taps up to now. A first type for a standard liquid flow and a second type for an increased liquid flow. The production of these dispensing taps is complicated and not easy to manage, creating very expensive accessories. The optimization of the universal dispensing tap 2 manages to cover all market needs by only modifying the width of the front holes, and allows for a tap that is easy to produce and very low cost, which provides an extreme advantage to the end consumer. In detail, analyzing only the part of the tap that is adapted to this application, it is possible to see, referring to Figure 16, the stop disk 2.4, under which the cylinder is positioned on which the first upper sealing diameter 2.6 is shaped and under which an insertion and lower sealing cylinder 2.5 is located. Below the insertion and lower sealing cylinder 2.5, there is the chamfer 2.3 to facilitate the entry and attachment of the geometries found on the main body 4. Below the entry chamfer 2.3, there is the third sealing area of the universal dispensing tap 2, and underneath there is a sharp-edged area 2.2 which, when it is in operational coupling with the geometry of the main body with flexible lip 4.3, generates the operational seal and the relative irreversibility of the mechanical coupling, thus avoiding and preventing the universal dispensing tap 2 from detaching from the inventive tap 1 once operationally connected. On the tip there are one or more holes, which can be shaped in different widths (AO and BO) based on the flow of liquid that has to be obtained during dispensing. In this way, there is a single tap for multiple versions, optimizing production and reducing costs.

[0061] With reference to Figure 17, the delivering probe 3 is illustrated with a stop disk 3.4 under which the cylinder is positioned on which the first upper sealing diameter 3.6 is shaped, and under which the lower insertion and sealing cylinder 3.5 is located. Below the lower sealing diameter 3.5, there is a chamfer 3.3 to facilitate the entry and attachment of the geometries found on the main body 4. Below the entry chamfer 3.3, there is the third sealing area of the delivering probe 3, and underneath there is a sharp-edged area 3.2 which, when it is operationally coupled with the geometry of the main body with flexible lip 4.3, generates the operational seal and the relative irreversibility of the mechanical coupling, thus avoiding and preventing the delivering probe 3 from being detached from the inventive tap 1 once operationally connected. On the tip there are one or more 3.1 holes which can be shaped in different widths (AO and BO) based on the flow of liquid that has to be obtained during dispensing.

[0062] In its main configuration illustrated in Figures 1 to 17, in detail, it is possible to identify, by referring to Fig. 5, the section of the tap 1 of the invention, assembled and in the closed and transport position in its preferred configuration .

[0063] In particular, refer to Figures 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13 where the closing steps and the various opening steps of the inventive tap 1 are highlighted with the various configurations of available accessories.

[0064] In particular, with reference to Figure 5, it is possible to see the tap 1 in section and in the closed position, with the upper tamper evident cap 5 assembled and the membrane 6 welded to form a double seal of guarantee together with the upper tamper evident cap 5 .

[0065] Figure 9 represents the step of removal by the end customer of the upper tamper evident cap 5 from the assembly IB formed by the main body 3 and the membrane 6 , preferably but not limited to , operatively welded to the main body 4 . The inventive tap 1 is now able to receive the accessories 2 or 3 necessary for dispensing .

[0066] I f we first consider the situation involving the insertion of the delivering probe 3 , there i s the first insertion step in Figure 10 .

[0067] In Figure 10 it i s possible to see the insertion of the delivering probe 3 into the main body 4 . In this step the tamper evident protection membrane 6 is still intact , while the protruding circular geometries obtained on the delivering probe 3 and on the main body 4 begin to interfere with each other ( 4 . 4-3 . 9 ) and begin to form a first operational safety seal . At this stage , the assembly is not yet stably constrained and is not able to deliver the contained liquid, preferably inside the BIB .

[0068] Figure 11 shows the delivering probe 3 fully inserted and irreversibly locked on the main body 4 . At this stage , the delivering probe 3 is stably locked to the main body 4 due to the cooperation of the geometries 3 . 2-4 . 3 . The tamper evident membrane 6 has been completely drilled and allows the delivery of liquid from the delivering probe 3 . The circular sealing geometries present on the delivering probe 3 and on the main body 4 cooperate ef fectively to guarantee a perfect seal to the liquids with the operating couplings 3 . 5-4 . 4 and 3 . 6-4 . 1 . At this stage , the inventive tap assembly 1 and the delivering probe 3 are in the open position, stably and irremovably constrained .

[0069] With reference to Figure 12 , instead, the first step of insertion of the universal dispensing tap 2 into the main body 4 of the inventive dispensing tap

[0070] 1 is illustrated, when the upper protecting tamper evident cap 5 has been removed as illustrated in Figure 9 . In this step, the protective membrane 6 i s still intact , while the protruding circular geometries obtained on the universal dispensing tap

[0071] 2 and on the main body 4 begin to interfere with each other ( 4 . 4-2 . 9 ) and begin to create an initial operational safety seal . In this step, the assembly is not yet stably constrained and is not able to dispense the contained liquid, preferably inside the BIB.

[0072] Figure 13 illustrates the universal dispensing tap 2 fully inserted and irreversibly locked onto the main body 4. At this stage, the universal dispensing tap 2 is stably locked onto the main body 4 due to the cooperation of the geometries 2.2-4.3. The tamper evident membrane 6 has been completely drilled and allows the dispensing of liquid from the universal dispensing tap 2. The circular sealing geometries present on the universal dispensing tap 2 and on the main body 4 cooperate effectively to guarantee a perfect seal for liquids with the operating couplings 3.5-4.4 and 2.5-4.1. At this stage, the inventive dispensing tap 1 and universal dispensing tap 2 assembly is in the open position, permanently and irremovably constrained.
