    TECHNICAL FIELD
    [001] The present invention concerns the field of cans for containing a liquid. In particular, it concerns beverage cans, such as beer, soft drinks, tonic water and the like, allowing a high and homogeneous distribution rate. BACKGROUND OF THE INVENTION
    [002] Drink cans have been on the market for several decades, having undergone a series of developments, such as the progressive passage of a "detachable pull tab" in which a dotted section of closed back is attached to a ring tab , even a type of "pressure tab", in which no element is detached from the can when opened. Since in both cases an actuating end of a tab has to be pulled from the plane formed by the upper end of the can to open a dispensing zone, such tabs are here referred to indiscriminately as "pull tabs".
    [003] It quickly became apparent that cans with a single dispensing opening led to a limited dispensing rate and, in particular, the drink to come out in gushes, due to the difficulty of such systems balancing the pressures from the inside and outside of the can when dispensing. It was found that by providing the top of the can with a second breathing opening, spaced from the dispensing opening, a flow of liquid out of the can was achieved much more fluidly, since the pressure inside the can could instantly adapt at ambient pressure through said breath opening. Many double can opening systems have been proposed in the art with very different opening mechanisms.
    [004] US4213538 proposes a can with a can top equipped with two dotted lines forming closed loops defining two areas to be pressed inwards with a finger or an external tool. An alternative solution is to attach a pull tab to a rivet located between two areas defined by dotted lines, so that the tab can be pushed to both sides to press a first and then a second area into the can like a saw , as disclosed in US5695085 or US5397014. In some cases, a single pull tab is first pulled upward to push the dispensing zone and then pressed down to its initial position and then further down to press the breathing zone, as in US2010 / 0018976, US2011 / 0056946, W02009 / 078738. These systems, however, have the problem that the vent can be accidentally opened if pressure is applied to the tab. To solve this problem, it was proposed not to align the first and second openings with the rivet by coupling the tab to the top of the can. In this way, after opening the dispensing opening, the pull tab must be turned on the rivet axis at the corresponding angle of deviation to face the breathing area and only then pushed down to press the breathing area inside the can as revealed in W02008 / 023983. In a first embodiment, the actuating end of a tab is first pulled upwards to open the dispensing opening, then rotated 180 ° to face the diametrically opposite breathing area, the enduring end being pulled up again to open the breathing opening in the same way as the delivery opening was opened, as in US5494184. W02010 / 046516 discloses a can comprising a main pull tab and a secondary lever, both fixed to the top of the can by a single rivet, where the secondary lever is placed in the puncture position when lifting the main pulling tab to pierce the distribution area, after which the main lever is brought to its original position, with the secondary lever taken to the puncture position in front of the breathing area, which is opened by pressing the main pull lever further down. This system prevents any accidental opening of the vent. All of these systems have in common that several movements are necessary to open the dispensing and breathing openings, which is quite inconvenient, particularly when the user has only one free hand to open the can.
    [005] Solutions have been proposed in the technique to open the distribution and breathing openings with a single movement. US3307737 discloses a single pull tab coupled to a distribution area and a breathing area, each forming a closed loop. When pulling on a free end of the pull tab, the vent is pulled first from the top of the can, and then from the dispensing area. The drawback of this very old system is well known, as it causes waste that usually ends up in the soil and represents an environmental threat and a source of injuries. CA2280461 proposes to engage the ring end of a pull tab with a rivet with a dotted line of breath forming a closed loop. When pulling said ring end to pierce the dispensing area, the breathing area is pulled from the top of the can. This system has the disadvantage that it takes a lot of force to pull the breathing area from the top of the can without the said design having any leverage to do so. US2003 / 0098306 proposes an improvement on the previous system by providing a second lever articulated with the main pull tab at the level of the breathing area rivet, so that the main pull tab is pulled when pulling the second lever, thus giving greater coupling. W02004 / 035399 and US3326406 disclose systems in which a single pull tab is attached to the top of the can with a first rivet and a breathing area with a second rivet. In contrast to the preceding systems, here both the dispensing and breathing areas are pushed into the can by pulling up on the pull tab at a point forming a triangle with the first and second rivets forming sharp angles. Leverage is provided by the altitude of the triangle that crosses the line between the two rivets.
    [006] All these efforts to include a breath opening that can be opened as easily as possible solved the problem of the gusts and increased the distribution rate to about 5 1 / min, which is about twice the flow rate obtained with a can single opening.
    [007] The present invention provides a can that allows to further increase the distribution rate. Summary of the invention
    [008] The present invention is defined in the attached independent claims. Preferred modalities are defined in the dependent claims. In particular, the present invention relates to a can containing a liquid and comprising an upper end, said upper end comprising: (a) A distribution area defined at said upper end by a first dotted line, (b) An area of distribution breath defined at said upper end by a second dotted line (31B) separate from the first dotted line, (c) a first rivet located between the breathing and distribution areas, for coupling to the upper end, (d) a pull tab for drill the distribution areas (3A) to open a distribution opening; (e) Means for opening the breath opening;
    [009] Characterized by the fact that the distribution area has a dimension (d) along the diameter of the upper extremity, passing through the first rivet greater than or equal to the radius (R) of the upper extremity.
    [010] This geometry allows to increase the area of the distribution opening, while benefiting from the advantages provided by a breathing opening. To avoid the generation of waste, it is preferable that no element of the main body can be detached when using a can. This can be achieved, for example, by ensuring that the first and / or second dotted lines form an open loop, so that when lifting the actuating end of the pull tab the delivery area and / or breathing area are folded in a line defined between two open ends of the respective dotted lines. Alternatively, the first and / or second dotted lines may form a closed loop, but should then comprise a dotted section much smaller than the rest of the dotted line, so that when lifting the actuating end of the pull tab, the distribution area and / or breathing area fold over a line defined by the surface section of the dotted line.
    [011] It is preferable that both the delivery and breathing openings can be opened in a single movement of the pull tab. This can be achieved through solutions revealing single-motion opening systems referred to earlier in the state of the art section. However, alternative solutions are preferred. For example, the means for opening the breath opening may comprise a secondary lever coupled to the upper end by a second rivet, said secondary lever comprising a piercing end suitable for piercing the breathing area to open a breath opening upon raising from the end. upper side an opposite actuating end of said secondary lever, and in which the secondary lever and pull tab are interconnected so that the lifting of the actuating end of the pull tab triggers the lifting of the actuating end of the secondary lever, thus causing the opening of the delivery and breathing openings in one movement
    [012] In an alternative solution to open both the delivery and breathing openings in one movement, the breathing area is located on the opposite side of the rivet from the delivery area, and the first and second dotted lines are separated from each other. another for at least one twist strip of the can top material suitable to function as a twist joint when lifting the actuating end of the pull tab from the top of the can, so that the dispensing opening is opened when pushing the area of delivery into the can, a breathing opening being opened by pulling the breathing area out of the top end of the can, thus opening both the delivery and breathing openings in one movement. In a preferred embodiment, the first and second dotted lines are substantially two Ω across from each other on their open sides, the rivet being located between them, the torsion strip being defined by the area separating the legs substantially straight from the Ω in which the curved portion of the second dotted line that defines the breathing area is substantially smaller than the curved portion of the Ω of the first dotted line that defines the distribution area. The second dotted line defining the breathing area may be deeper than the first dotted line defining the distribution area to facilitate opening the breathing opening, without unduly increasing the force required to lift the pull tab compared to a can. traditional single opening.
    [013] Alternatively, the opening of the delivery and breathing openings can be performed in more than one movement, preferably two movements. For example, as proposed by W02010 / 046516, the opening of the second breath opening can be accomplished through a secondary lever mounted on the same rivet as the pull ring, the drilling end of the secondary lever being placed in contact with the second breathing by first lifting the pull tab to press and open the dispensing area, followed by pulling the pull tab back to its initial position. At that time, the perforating end of the secondary lever is sandwiched between the pull tab and the breathing area, the latter being pressed into the can by pressing the main pull tab further down.
    [014] A can according to the present invention is particularly suitable for containing and distributing a beverage selected from the group of alcoholic or non-alcoholic or other fermented beer, soft drinks, tonic water, juice, energy drinks, soup, snacks. Such cans are preferably made of aluminum, aluminum alloy or tinplate. BRIEF DESCRIPTION OF THE FIGURES
    [015] For a more complete understanding of the nature of the present invention, reference is made to the following detailed description, made in conjunction with the accompanying drawings in which:
    [016] Figure 1: shows a top view of the top of the can of (a) a double opening can of the prior art and (b) a can according to the present invention.

    [019] Detailed description of the invention
    [020] As can be seen in Figure 1, a can according to the present invention comprises an upper end similar to that of traditional commercially available cans to date, with a distribution area (3A) defined at said upper end by a first dotted line (31A) and a pull tab (2A) coupled to the upper end by a first rivet (4A). The pull tab (2A) comprises a drill end (21A) overlapping the distribution area and an opposite actuator end (22A) which, when lifting from the plane of the upper end of the can, presses the drill end (21A) against the distribution, breaking the dotted line and pushing the distribution area against the can, thus opening the distribution opening (13A). Of course, it is much more preferable that when opening the dispensing opening (13A) neither the pull tab (2A) nor the dispensing area (3A) detach from the upper end of the can. This can be achieved either by not closing the path formed by the first dotted line (31A) or by providing a portion of said line with a more superficial (i.e., less deep) dotted line than the rest of the contour. In any of these ways, when pressing the punching end (21A) of the pull tab against the distribution area (3A), the latter will fold over a line between the two ends of the dotted line back open or over the portion most superficial of the dotted line.
    [021] The breathing area (3B) is defined by a second dotted line (31B) and is located at the upper end of the can, usually opposite the distribution area (3A) in relation to the rivet (4A). The breathing area (3B) should most preferably not be separated from the upper end of the can when opening the breathing opening. As for the distribution area (3A) discussed above, the dotted line (31B) defining the breathing area (3B) must define an opening path or comprise a more superficial dotted portion, to allow the breathing area (3B ) fold over said non-dotted portion or superficial dotted line. The breathing area (3B) is generally smaller in size than the distribution area (3A), since the first only needs to ensure the pressure balance during the distribution of the liquid out of the can, and a gentle depressurization when open the can.
    [022] With the exception of some embodiments, the rivet (4A) coupling the main pull tab (2A) to the upper end of the can is traditionally located in the geometric center of the upper end of the can. This is particularly true for cans comprising dispensing and breathing areas, since the two openings are generally located on both sides of the rivet. There are, of course, some exceptions as in W02004 / 035399, which reveals a can comprising two openings that can be opened with a single movement of a single pull tab attached to the top end of the can by two rivets, none being in its center. The area of the top of the can to provide a dispensing area is therefore generally limited to half the area of the upper end of the can and, consequently, the size of the dispensing opening (13A) is correspondingly limited. The present invention solves this problem quite simply by deflecting the rivet (4A) in relation to the upper end of the can, but, unlike W02004 / 035399, the distribution area in a can according to the present invention has a dimension (d) along the diameter of the upper end passing through the first rivet (4A) greater than or equal to the radius (R) of the upper end. This simple solution allows you to increase the available area to locate the distribution area, the size of which can be increased accordingly. With a larger area of distribution, together with a breath opening, the flow is more homogeneous (no bumps) and faster, allowing you to empty a can very quickly. For beer applications, a large area is advantageous as it allows better control of foam formation, without excess as can happen with the turbulences often caused by smaller openings.
    [023] Contrary to what might be expected, there is no particular problem in the location of the breathing area opposite the distribution opening in relation to the first deflected rivet (4A) and it is even possible to apply a single movement opening system to the opening of both delivery and breathing openings (13A, 13B).
    [024] For example, in a first embodiment illustrated in Figure 2, opening the breath opening can be ensured by a secondary lever coupled to the upper end by a second rivet (4B). As illustrated in Figure 2 (a), the first and second rivets (4A, 4B) and distribution and breathing areas (2A, 2B) are preferably substantially aligned in a diameter of the upper end of the can, in a sequence (a) distribution area (3A), (b) first rivet (4A), (c) breathing area (3B) and (d) second rivet (4B). The secondary lever (2B) has an actuating end (22B) and an opposite drilling end (21B) overlapping the breathing area (3B), so that when lifting the actuating end (22B) of the secondary lever (2B), its perforating end (21B) applies pressure against the breathing area (3B) capable of breaking the second dotted line (21B) to push and bend the breathing area (3B) into the can.
    [025] Instead of operating the pull tab (2A) to open the dispensing opening separately from the secondary lever (2B) to open the breathing opening, and thus needing at least two movements to open both openings, at present embodiment the secondary lever (3B) is interconnected with the pull tab (3A) so that lifting the actuating end (22A) of the pulling tab triggers the lifting of the actuating end (22B) of the secondary lever (2B) , thus causing the opening of both distribution and breathing openings (13A, 13B) in a single movement.
    [026] The interconnection of the secondary lever (2B) and the pull tab (2A) can be achieved by providing the actuator end (22A) of the pull tab (2A) with an opening - as is often present in pull tabs. single-opening cans - and slide the secondary lever (2B) through said opening so that the actuating end (22B) of the secondary lever (2B) rests on top of the pull tab (2A), while the perforating end (21B ) and second rivet (4B) of said secondary lever (2B) are positioned below the pull tab (2A). With this configuration, lifting the pull tab (2A) to open the dispensing opening pushes up the actuating end (22B) of the secondary lever (2B), settling and sliding on an edge of the raised opening of the pull tab as it moves. is raised. The secondary lever (2B), attached to the top end of the can by the second rivet (4B) is thus tilted by pressing the drill end (21B) down against the breathing area (3B) until the second dotted line (31B) breaks to open the breath opening.
    [027] In a preferred embodiment of the arrangement shown in Figure 2, the secondary lever (2B) is in the form of a plate extending between a first and second planes substantially parallel substantially parallel to the plane defined by the upper end of the can , with a first piercing portion comprising the piercing end (21B) and extending along said first plane, and a second actuating portion comprising the actuating end (21B) and substantially extending along said second plane, the first perforating portion comprising a hole for receiving the second rivet (4B). The distance between the two planes is substantially equal to the distance between the upper surface of the pull tab (2A) and the surface of the upper end of the can. The actuating end (22B) of the secondary lever (2B) can be flat and rest on top of the main pull tab (4A) or, as shown in Figure 2 (b), in the form of a pin extending parallel to the upper end of the can and resting on the top surface of the main pull tab. With this geometry, the actuating portion of the secondary lever (2B) can rest on the top of the pull tab (2A) and the perforating portion of the secondary lever (2B) can rest on the surface of the upper end of the can.
    [028] In a second embodiment, illustrated in Figure 3, the breathing opening (13B) can be opened by twisting or bending a twisting strip (5) by lifting the actuating end (22A) of the pull tab main (2A). In this embodiment, a single pull tab (4A) is attached to the top end of the can with a single rivet (4A) and is used to open both dispensing and breathing openings (13A, 13B) in a single movement of the pull tab. The first and second dotted lines (31A, 31B) are separated from each other by an area of the upper material of the can defining at least one twist strip (5) suitable to function as a twist joint when lifting the actuator end (22 ) of the pull tab (2) out of the top end of the can. As shown in Figures 3 (a) and (b), the actuating end (22A) of the pull tab (2A) is raised, the drill end located opposite it in relation to the rivet (4A) presses on the distribution area (3A ), breaking the dotted line (31A) and pushing the distribution area (13A) into the can. The inclination of the pull tab over the rivet creates a torsional moment in the area of the upper end of the can comprising the rivet, which results in an inclination of the rivet itself in relation to the plane defined by the upper end of the can. By creating a suitable torsion strip (5) on or around the rivet, the torsional moment acting on the area around the rivet can be used to create an upward lifting force capable of breaking the second dotted line (31B) and to lift the breathing area (3B) off the top end of the can to open the vent (13B) (see Figure 3 (b) and (c)).
    [029] The distribution area (3A), the rivet (4A) and the breathing area (3B) are preferably aligned on a first diameter of the upper end of the can in that order. The at least one twisting strip (5) acting as an articulation over which the rivet (4A) can be inclined, can generally be substantially normal with respect to said first diameter. Once the rivet coupling the pull tab (2A) to the top end of the can defines an area of greater flexural rigidity, the movement of pulling the actuating end (22A) of the pull tab (2A) - which is sandwiched between the upper end of the can and the rivet head (4A) - is necessarily accompanied by some inclination of the rivet and the creation of a flexion field at the upper end of the can that surrounds it. The creation of a torsion strip (5) with lower flexural stiffness increases the difference in flexural stiffness between the area of the rivet and the area surrounding it, allowing to increase the magnitude of the flexion field behind the area of the rivet in relation to to the distribution area (3A). To further increase the articulation effect, the torsion strip (5) can be provided with secondary dotted lines that are much more superficial than the first and second dotted lines (31A, 31B), since they are not intended to break but that just facilitate the flexing of the strip. When designing the first and second dotted lines properly, however, the secondary dotted lines are not necessary to provide the desired articulation effect.
    [030] In order to facilitate the opening of the breath opening (13B), the second dotted line (31B) defining the breathing area (3B) can be deeper than the dotted line (31A) defining the distribution area ( 3A). In this way, less force is needed to break the second dotted line (31B), and since the breathing area (3B) is generally substantially smaller than the distribution area (3A), the force applied by the pressurized gas inside from the can to the second dotted line is less than that applied to the distribution area, thus reducing the risk of accidentally breaking the breathing area.
    [031] The first and second embodiments presented above allow for a breathing opening (13B) whose opening combined with the dispensing opening (13A) can be triggered by the same unique movement as has been used by generations of consumers with opening cans only traditional. Unlike the solution proposed in CA2280461, the force required to open both openings is not much different from that required to open traditional single-opening cans because the geometry of the opening system of the present invention allows for a substantial leverage effect. With the present invention it is therefore possible to combine the advantages of a breath opening, a unique opening system and a large distribution area allowing the distribution rate to be increased and homogenized accordingly.
    [032] Different can opening systems can be implemented in accordance with the present invention; if the two openings cannot be opened with a single movement, there are interesting two-movement systems that can easily be applied to the present invention. For example, the system disclosed in W02010 / 046516, the disclosure of which is hereby incorporated by reference. The single rivet coupling the main tab and the secondary lever only has to be deflected in relation to the center of the upper end of the can to allow a larger distribution area (3A) to be defined, thus increasing the distribution efficiency.
    [033] A can according to the present invention is particularly suitable for containing drinks. For example, alcoholic or non-alcoholic beer or other fermented drinks, such as cider, low-malt beer, sparkling wine and the like, soft drinks, tonic water, juices, energy drinks, pre-mixed long drinks a spirit drink and a soft drink, milk, condensed milk, soup, sauce and the like. The can can be made of aluminum, an aluminum alloy or tinplate.
