    Description


    [0001] The present invention refers to a delivering tap of liquids from vessels, in particular the so-called vessels of the "bag-in-box" type (herein below called BIB).

    [0002] Purpose of the present invention is creating a tap which is completely made of plastic material (then easily recycled) and which is adapted to connectors present on the market, actually replacing an old tap version currently marketed by company Maierhöfer (™).

    [0003] The tap configuration produced by the above company is known in the art and is the major reference of this product.

    [0004] This version, in particular the one for the adapter of connectors of company CMB (™), has an operating/actuating process of this type (for the version with quick connection with balls):
    • step 1: providing a connector present on the market;
    • step 2: inserting the connector on the main body of the tap;
    • step 3: providing the internal peg of the connector which performs the operating seal on the tap turret, on which a sealing a O-ring is assembled;
    • step 4: the tip of the internal peg centrally pushes an actuator of the tap, which frees the liquid outlet hole of the tap present on the body; the actuator moves by a pre-set amount, till it is blocked on a plane geometry of the body and, from then on, the central actuator operates as fixed abutment to open the center of the connector peg, to free the passage of the connector, creating an open channel connector/ tap;
    • step 5: behind the central actuator of the tap, a metallic spring (or the same actuator will be shaped as an elastic dome, also supported by a metallic spring therein) is assembled, which allows its automatic closure (following the above described reverse cycle), allowing to take back the two systems with connector and tap in their closing position.


    [0005] Such taps however have some drawbacks.

    [0006] For example, some are not completely made of plastic material, but use metallic springs therein (as occurs for the Maierhöfer tap) so that, once having disconnected it from the connector, it goes back to its closing position, avoiding liquid leakages.

    [0007] The presence of a metallic spring in a set of plastic pieces makes the tap ecologically not interesting in terms of recycling.

    [0008] Such taps, further, has not a real and actual warranty seal (of the tamper-preventing type), capable of pointing out a counterfeit or a simple opening thereof, but are only equipped with a small "dust-preventing" plug, whose purpose is protecting the tip of the tap from dust or dirt. Such system, present on all taps being manufactured (both the above mentioned major tap, and also the several copies of this tap), currently does not guarantee against tampering with the product contained in the BIB, since the small plug can be easily removed and re-inserted without the end user getting aware of it.

    [0009] Sometimes, due to the need of providing a completely aseptic tap (and due to resistance to aseptic treatments), the welding of an operculum, preferably made of aluminum, but also of other materials adapted for such purpose (not shown in the drawings but being part of the invention) is required on the tip of the tap, in order to seal and protect the connection area during the sterilization cycles of the taps/bags.

    [0010] In this case, it will not be necessary any more to place the above described tamper-preventing seal, but there remains in any case the very big advantage of an end user to understand whether the tap has been used / tampered with, since the aluminum operculum will be stably welded to the tap body.

    [0011] Once removed, evidence of the opening will appear, since it will not be possible any more to stably place again the seal onto the tap.

    [0012] Document WO-A1-01/98158 discloses a tap according to the preamble of Claim 1.

    [0013] Object of the present invention is making a simple and ecologically acceptable tap, which however allows being adapted to the connectors present on the marked, not requiring their modification and changing the actuating system, making it unique and universal for all marketed connectors (as can be better seen in Figure 6). Known connectors of company CMB (™) present on the market are currently as many as the beverage to be delivered (the external geometry and the type of connection change depending on the beverage manufacturer), and therefore the tap of the invention will have to be able (by changing its external geometry) to be adapted without problems to all versions of CMB (™) connectors or the like present on the market.

    [0014] Herein below, one of the arrangements of CMB connectors present on the market will be shown (in Figure 6), more specifically the one with quick connection with balls of the Jolly (™) type for a Pepsico (™) product.

    [0015] The connector in Figure 8 will have to be fastened, by means of a fastening ring 16 present on the main body of the inventive tap and a "ball" system 15 present on the CMB (™) connector 8 (typical bayonet-type fastening) and perform a sealing on the internal walls of the new tap of the invention.

    [0016] Simultaneously, by means of the thrust of the connector itself, an internal pin 12, which will "descend" during its fastening on the tap interior, will have to open the inventive tap, which however, in turn, will have to open the liquid passage of the connector 8, creating an open channel for the passage of liquid. Everything will be better explained below, where the differences and the advantages between the new tap of the invention and the old tap marketed by company Maierhöfer (™) (not shown) will be better appreciated.

    [0017] A further object of the invention is providing an improved delivering tap which is made with a minimum number of parts, both equipped with an internal thrusting membrane, which is the main member of the tap, which allows performing automatic closing and opening operations of the tap without using metallic springs, and a better oxygen seal, also due to the high-seal elastomeric material of which it is made and preventing / decreasing the liquid oxidation inside, since the tap of the invention, with respect to those present on the market, strongly decreases the amount of air inserted in the BIB due to its special geometries.

    [0018] A further object of the present invention is providing a tap as described above, which performs an efficient sealing of the valve on the body, thereby obtaining a great increase of the oxygen barrier. Moreover, it will provide a strong decrease of the amount of oxygen which will enter the bag once having finished to fill it up, since all system members are housed on the tap back with respect to the delivery area, thereby occupying the volume which is usually free and therefore full of air like in the traditional tap.

    [0019] A further object of the present invention is providing a tap as mentioned above which is equipped with a warranty seal of the tamper-preventing type, which irreversibly points out its opening or, if the application needs particular aseptic or sterilization treatments, equipped with an aluminium operculum (not shown in the drawings) welded onto the body to protect it and to point out its opening (in this case, it will not be necessary any more to place also the tamper-preventing seal on the tap).

    [0020] The tap of the invention, being equipped with a high oxygen barrier, is suitable for aseptic applications.

    [0021] The above and other objects and advantages of the invention, as will result from the following description, are obtained with a delivering tap as claimed in claim 1. Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims.

    [0023] With reference to the Figures, a preferred embodiment of the delivering tap 1 of the invention is shown and described as a non-limiting example. It will be clear from a skilled person in the art that the described tap 1 can be made with equivalent shapes, sizes and parts, and will be capable of being used for various types of vessels, for example the so-called "Bag-in-Box" ones, but also vessels or the rigid or semi-rigid types, or others.

    [0024] The tap 1 of the invention is used for delivering liquids from a vessel (not shown), and substantially comprises an elongated supporting body 2, preferably cylindrical, equipped at its liquid delivering end 0A, with means 2.7, preferably shaped as a ring, for fitting and liquid sealing, and at its opposite end 0B, with means 2.6, preferably shapes as a ring, for connecting and sealing to the mouth (for BIB systems) and for preventing the removal from the vessel, by means of a connecting mouth (not shown) welded on the bag (in case of BIB). In the front area 0A there is a cylindrical extension 2.9, on which fitting geometries 2.8 are obtained, depending on marketed CMB (™) connectors 8.

    [0025] In the present invention, the typical CMB (™) type for Pepsico (™) with ball-type fastening 15 will be analyzed. Such connector 8 is composed, as can be seen in Figure 8, of a main body 10 inside which the devices which allow automatically opening and closing the connector 8 are operatively placed, and especially pin 12 on which the O-ring 13 is assembled. Behind the pin 12, the metallic spring 12 and the closing plug 9 are placed. On the lower part pieces are placed (quick, ball-type fastening of the connector 8) which operate to block the connector 8 on the geometries of the tap 1 present on the body 2, which will be described below: especially, the sealing ring 16 and the spring for automatically closing and blocking the balls 15, more precisely the metallic spring 14. The supporting body 2 is equipped with at least one first opening 2.10 for exiting the liquid. It is equipped with an external geometry 2.8 adapted to be connected to the connector 8 by means of the balls 15 and the ring for blocking the balls of the connector 16.

    [0026] On the opposite end 0B to the above described liquid delivering geometry 0A shown in Figure 11, there are sealing rings 2.7 which are adapted to be operatively connected to the connecting mouth (not shown) which in turn is welded to the bag of the BIB and operates as connecting element between the tap and the BIB bag.

    [0027] There is a ring 2.6 with sharp edge (area 0B) which operates as abutment for preventing the removal of the tap 1 once inserted in the connecting mouth. There is also, inside the front cylindrical geometry 2.9 (area 0A) inside of the body 2, a chute 2.1 which operates as guide / seat / abutment of the internal sealing O-ring 17 assembled on a central pin 4 in its seat 4.5, and it performs an operative seal, as shown in Figure 3.

    [0028] There are, inside the rear part of the body 2 (area 0B in Figure 11), four special internal geometries 2.5, preferably of the wedge-type, to enable the entry of the plate 5, adapted to support/allow the abutment fastening of the plate 5. Such geometries 2.5, obtained by means of successive movements of plates and males, allow constraining the plate 5 to the body 2 stably and mechanically in an unmovable and safe manner, as shown in Figure 3, and they operate as abutment onto a dome-shaped valve/spring 3 made of elastomeric material, which in turn is stably assembled, and guides the central pin 4 by means of the fastening geometries 4.3 present on the central pin 4 and of the geometries 3.2 present on the dome-shaped valve/spring 3 made of elastomeric material.

    [0029] Externally, there is a complete disk 2.11.

    [0030] Outside the elongated body 2, there are fastening geometries 2.2 useful for fastening the tamper-preventing seal 6 and the seat 2.3 of the external sealing O-ring 7.

    [0031] Further, in the rear area of the tap (area 0B in Figure 11), there are rounded discharge areas 2.4, which are used to better and completely empty the BIB vessel, avoiding that, during the last emptying step, the film performs a sucking effect (normally the vessels which contain concentrated liquids, in order to enable the emptying, use a pump, preferably a peristaltic pump, which increases the chance of a suction effect of the film on the tap at the end of the vessel life, in turn almost emptied) on the remaining tap 1, avoiding the final emptying. Such geometries 2.4 enable the complete emptying of the BIB bag.

    [0032] The tap 1 of the invention further comprises the central pin 4 having an elongated shape and equipped with fastening geometries 4.3 of the elastic dome 3 on one end, and, on the opposite end, with a geometry 4.5 which is the seat of the O-ring 17, which performs an operating seal on the internal chute 2.1 of the body 2.

    [0033] Moreover, there are four stiffening geometries 4.4 of the pin 4, which also operate as guide to have an axial sliding of the pin 4 inside the body 2, when it will be activated by the connector 8 in an opening thrust.

    [0034] On the lower part, under the fastening geometry of the dome 3, there is an abutment plane 4.1 which generates an opening of the connector 8 during its operating step, once this is operatively connected to the tap 1 of the invention.

    [0035] There is also a central driving pin 4.2.

    [0036] Further, the tap 1 is equipped with an elastic valve/spring 3, preferably shaped as a dome, which is operatively connected to the central pin 4 by means of the geometry 4.3 with the elastic valve geometry 3.2.

    [0037] In turn, the valve 3 rests on and has as operating abutment, the plate 5, by means of the plane geometry 5.1, as shown in Figure 3. The dome-shaped elastic valve 3 allows automatically closing the tap 1 of the invention.

    [0038] The tap 1 further comprises a read abutment element (or plate) 5 which, once stably connected onto the body 2 by means of a fastening of the bayonet type, is inserted by exploiting the "recesses" 5.3 and making them pass next to the small teeth 2.5 of the body 2 and, through a rotation of the bayonet fastening type, sending them to engage, or better stably abut, in the abutment seats 5.7 present on the plate 5. Once having engaged/assembled the plate 5 on the body 2, this latter one pushes onto the elastic dome 3.3 due to a plane 5.1 which, in turn, being stably assembled on the central pin 4 by means of the geometry 4.3, pushes the O-ring 17 assembled on the central pin 4 in the seat 4.5 in operating seal on the internal chute 2.1 of the body tap 2.

    [0039] The plate 5 is equipped with through recesses 5.6, useful to allow the passage of liquid when the tap 1 is in its opening position, and with stiffening ribs 5.2 of the plate 5, useful to provide a structure to the plate 5 itself.

    [0040] There are also a central peg 5.5, useful for centering when assembling the tap 1, and small blocking teeth 5.4 useful to block the plate 5 onto the small teeth of the body 2 (2.5) and to avoid its rotation.

    [0041] The tap 1 further comprises at least one upper closing element (or tamper-preventing seal) 6, which goes in operating coupling with the body 2 due to the geometries 6.1 present on the tamper-preventing seal 6 and to the seat 2.2 present on the body. Such seal 6 is used for hygienically protecting the tap 1 during all steps preceding the operation connection between tap 1 and connector/the 8. It further provides evidence of opening/tampering, due to its tearable band 6.2, which, once broken/torn, due to the guided breakage bridges 6.4, is impossible to be restored and provides evidence of breaking to clients/users, safeguarding product and users themselves.

    [0042] There are also centering guides 6.3 on the body 2 to enable its assembling.

    [0043] Sometimes, for particular needs, the tamper-preventing seal 6 can be replaced by an aluminium operculum (not shown), which has the same function of the above described seal (opening evidence, product protection), since it is welded onto the body 2 and then, once removed, it is impossible to place it back again, thereby providing evidence of its opening, in addition to protection, for the tap 1.

    [0044] In particular, with reference to Figure 10, where the tap 1 of the invention is shown in section, but in its closing position, it can be noted that, in the main element or body 2, the central pin 4 is inserted, on which the toroidal sealing O-ring 17 is assembled in its suitable seat 4.5..

    [0045] The two assembled elements (pin 4 and O-ring 17) are assembled on the dome-shaped elastic element 3, whose purpose is pushing and perfectly matching in operating seal the O-ring 17 on the internal chute 2.1 of the body 2.

    [0046] The peg of the coupling O-ring 17 + pin 4 + dome-shaped elastic element 3 is given by the plate 5, once assembled in its operating position and blocked due to the elements 2.6 obtained on the body 2 and the elements 5.7 obtained on the plate 5.

    [0047] The elastic dome-shaped element 3 rests on the plane surface 5.1 of the plate 5 and pushes with the correct force the assembly composed of pin 4 + O-ring 17 against the chute 2.1 of the body 2, performing the operating seal with tap closed.

    [0048] With reference to Figure 9, it can be seen that the connecting by means of the quick fastening (in this case with balls 15) of the CMB (™) connector 8 or the like present both on the tap 1 (which obviously has the necessary external geometries to obtain and be regularly coupled with the connector 8 due to the geometries 2.9), and on the connector 8. By descending during the screwing step, the connector 8 operatively seals the tap 1 due to the external wall 10.1 of the connector 8. Simultaneously, the element 12 pushes onto the pin 4 and in particular onto the surface 4.6 of the pin 4 of the tap 1, making it open.

    [0049] When the descent of the assembly pin 4 + O-ring 17 + dome-shape elastic valve 3 ends its operating stroke and the central pin 4, due to its plane geometry 4.1, collides with the inside of the dome-shaped valve 3 in its plane 3.1, this latter one is blocked and simultaneously starts opening the connector 8, by virtue of the movement of the internal pin 12 of the connector 8 on which a sealing O-ring 13 is assembled, which, when the connector 8 is in its closing step, performs an operating seal on the internal chute 12.2.

    [0050] In this step, once having ended the complete operating descent of the connector 8 onto the tap 1, an open channel is created, which allows the continuous delivery of the product contained in the vessel (in this case a BIB).

    [0051] The flexible valve 3 is connected to the central pin by means of the geometries 4.3 and 3.2, thereby making the dome-shaped elastic element 3 generate from this coupling (and from the thrust on the plate 5 on the plane 5.1) the necessary force to automatically close again the assembly of the tap 1, once having removed the connector 8.

    [0052] Obviously, it is possible, by changing the geometries of the various pieces, to create variations of the tap 1 of the invention, which always fall within the scope of the enclosed claims.

    [0053] With the tap 1 of the invention, the problem of the metallic spring (not present any more) has been solved. The tap 1, being completely made of plastic, is recyclable and ecologically acceptable.

    [0054] With reference to Figure 10, it can be noted that the automatic handling and return members 5 and 3 occupy the majority of the space of the rear part of the tap 1. This arrangement offers less space for air and consequently such space decrease for air present on the back of the tap 1 (which is the one which will contact the liquid when the tap 1 is connected to the mouth) will coincide with less air inserted in the bag after filling it, and lower risk of oxidation with respect to the prior art tap arrangement, where the rear free space is occupied only by a metallic spring, but the remaining volume is occupied by air which enters in the bag and oxidizes the liquid contained therein.
