- the reduced thickness of T SR of the lid 12 at the line of weakness 36 may be no more than 0.5 mm, in some cases no more than 0.15 mm, in some cases no more than 0.05 mm, and in some cases even less.
- the opening system 18 comprises a spring 40 to assist in opening the beverage can 10 .
- the spring 40 is part of the inner side 16 of the lid 12 and configured to enlarge the pouring opening 20 after the actuator 22 is manually operated.
- the spring 40 is configured to enlarge the pouring opening 20 after the button 30 is manually pressed upon.
- a spring force exerted by the spring 40 therefore helps to create the pouring opening 20 , thereby facilitating opening of the beverage can 10 .

- the curved portion 76 of the spring 40 extends from the distal extremity 74 of the spring 40 in a rearward direction while projecting from the inner surface 52 into the interior 46 of the beverage can 10 , before extending in a forward direction and back towards the inner surface 52 .
- the linear portion 78 of the spring 40 connects the curved portion 76 to the proximal extremity 72 of the spring 40 .
- the spring 40 may be shaped in any other suitable way in other embodiments.
- the spring 40 has a rest position wherein its extremities 72 , 74 would not be parallel and collinear to one another such that, when the spring 40 is fastened to the flap 44 and to the base 52 , the extremities 72 , 74 are forced to be substantially parallel and collinear with one another and the spring 40 applies the spring force pulling on the flap 44 towards the interior 46 of the beverage can 10 and pushing on the anchoring portion 51 of the base 50 in an opposite direction.
- the spring 40 is fastened to the flap 44 by a proximal fastener 82 and to the anchoring portion 51 of the base 50 by a distal fastener 84 .
- the fasteners 82 , 84 are integral rivets joining the extremities 72 , 74 of the spring 40 to the flap 44 and to the anchoring portion 51 of the base 50 .
- the proximal fastener 82 extends into an aperture 87 of the proximal extremity 72 of the spring 40 and creates a depression 86 at the outer side 14 of the lid 12 .
- the distal fastener 84 extends into an aperture 89 of the distal extremity 74 of the spring 40 creates a depression 85 at the outer side 14 of the lid 12 .
- Each of the apertures 87 , 89 of the spring 40 may be manufactured before the fasteners 82 , 84 are inserted into the apertures 87 , 89 , or may be manufactured simultaneously, i.e., the manufacturing of fasteners 82 , 84 may create the apertures 87 , 89 of the spring 40 .
- the button 30 is disposed beside the fasteners 82 , 84 (i.e., not between the fasteners 82 , 84 such that it does not intersect an imaginary straight line interconnecting the fasteners 82 , 84 ).
- the button 30 is adjacent to the proximal fastener 82 .
- the button 30 is located on the frangible portion 34 of the lid 12 , such that the button 30 is configured to enter inside the beverage can 10 when manually pressed upon. More particularly, in this embodiment, the button 30 is part of the flap 44 . The button 30 is located near the line of weakness 36 of the frangible portion 34 . After the button 30 is manually pushed upon and the pouring opening 20 starts to be created, an area 67 of the pouring opening 20 where the button 30 was before the button 30 was pushed upon allows gas exchange between the interior 46 of the beverage can 10 and outside the beverage can 10 when the drinkable liquid is being poured.
- the lid 12 comprises a rim 92 disposed at a periphery 90 of the lid 12 and projecting upwardly from the base 50 of the lid 12 .

- the lid 12 is at least mostly (i.e., mostly or entirely) made of aluminum.
- the lid 12 is entirely made of aluminum. This may help for recycling of the lid 12 . Accordingly, in this example, the lid 12 is entirely recyclable.
- a metallic material 60 of the spring 40 is different from a metallic material 62 of the base 50 . More specifically, in this embodiment, the metallic material 60 is an aluminum alloy of the spring 40 and the metallic material 62 is an aluminum alloy of the base 50 which is different from the aluminum alloy 60 of the spring 40 .

- the aluminum alloy 60 of the spring 40 is aluminum alloy 7075-T6, while the aluminum alloy 62 of the base 50 is aluminum alloy 5182. Any other suitable aluminum alloys may be used in other embodiments.
- the spring force exerted by the spring 40 is sufficient to enlarge the pouring opening 20 once initiated by manually pressing upon the button 30 . Under the spring force, the spring 40 pulls on the flap 44 to continue tearing the lid 20 and enlarge the pouring opening 20 .
- the spring force exerted by the spring 40 may be at least 30 N, in some cases at least 40 N, in some cases at least 60 N, and in some cases even more.
- the spring force exerted by the spring 40 may also depend on an internal pressure of the beverage can 10 before it is open as the spring force and the internal pressure generally work against one another. For instance, the higher the internal pressure of the beverage can 10 is, the higher the spring force can be without causing failure of the frangible portion 34 without the button 30 being manually pressed upon. In some cases, the spring force may be opposed by the internal pressure of the beverage can 10 to counter a tendency of the spring 40 to pull downwards and inwardly deflect (e.g., bow) the base 50 of the lid 12 .
- a ratio of the spring force exerted by the spring 40 over the internal pressure of the beverage can 10 may be between 80 N/MPa and 105 N/MPa, in some cases between 105 and 130 N/MPa, and in some cases about 105 N/MPa.
- a cross-sectional area of the pouring opening 20 which is normal to a longitudinal direction of the beverage can 10 , is suitable for drinking or otherwise pouring the drinkable liquid and comparable to existing beverage cans.
- a ratio of the cross-sectional area of the pouring opening 20 over a cross-sectional area of the lid 12 normal to the longitudinal direction of the beverage can is at least 0.1, in some cases at least 0.15, in some cases at least 0.2, and in some cases even more.
- the cross-sectional area of the pouring opening 20 may be between 2 cm 2 and 8 cm 2 , in some cases between 2 cm 2 and 4 cm 2 , and in some cases about 2.8 cm 2 .

- the pouring opening 20 is larger than the button 30 .
- a ratio of the cross-sectional area of the pouring opening 20 over the cross-sectional area of the button 30 may be at least 2, in some cases at least 4, in some cases at least 6, and in some cases even more.
- the pouring opening 20 may have any suitable shape.
- the pouring opening 20 is noncircular. More particularly, in this embodiment, the pouring opening 20 is oblong. In this example, the pouring opening 20 is generally kidney-shaped.
- the beverage can 10 including the lid 12 , may be manufactured in any suitable way.
- the lid 12 is manufactured by pressing, using sheets of aluminum alloy.
- the lid 12 may be pressed once, or it may be manufactured by being pressed several times.
- a first pressing may cut the periphery of the lid 12 from a sheet of aluminum alloy
- a second pressing may apply a thread of the lid 12 (e.g., the button 30 , the line of weakness 36 , etc.)
- a third pressing may form the integral rivets 82 , 84
- a fourth pressing may fasten the extremities 72 , 74 of the spring 40 , the flap 44 and the anchoring portion 51 of the base 50 .
- a manufacturing process for the lid 12 may comprise one or more operations other than pressing (e.g., water jet cutting, water jet surfacing, etc.).
- the lid 12 may be seamed to the body 13 of the beverage can 10 in a seaming process comprising one or more steps involving a seaming chuck and a seaming roll to create a mechanical interlock between the lid 12 and the body 13 of the beverage can 10 .
- a compound may be used in a seam between the lid 12 and the body 13 of the beverage can 10 to further seal the lid 12 with the body 13 of the beverage can 10 , thus preventing gas or liquid to get through.
- the button 30 In use, when the button 30 is manually pressed upon (e.g., by the user's thumb), a stress is applied on the lid 12 near the frangible portion 34 , which creates stress concentration causing initial failure of the aluminum alloy 62 of the lid 12 on a portion of the line of weakness 36 .
- This initial failure weakens the frangible portion 34 of the lid 12 and the spring 40 creates further stress concentration on the weakened frangible portion 34 , at the line of weakness 36 , near the initial failure.
- the initial failure allows gas exchange between the interior 46 of the beverage can 10 and an environment of the beverage can 10 , thus allowing the internal pressure, which works against the spring 40 , to drop.
- This combination of events causes a propagation of the initial failure through the frangible portion 34 of the lid 12 along the line of weakness 36 .
- the spring 40 returns to its rest position, causing the flap 44 to move towards the interior 46 of the beverage can 10 and creating the pouring opening 12 .
- the lid 12 is configured such that another beverage can is stackable on the beverage can 10 without interference from the button 30 .
- the rim 92 of the lid 12 extends at least as high as the button 30 . In this case, the rim 92 of the lid 12 extends higher than the button 30 .
- the lid 12 including its opening system 18 , may be implemented in various other ways in other embodiments.
- the frangible portion 34 of the lid 12 may have various other shapes.
- the button 30 is between the fasteners 82 , 84 such that it intersects an imaginary straight line interconnecting the fasteners 82 , 84 .
- the button 30 is located near the line of weakness 36 of the frangible portion 34 and is connected to a remaining portion of the flap 44 by a portion 94 of the flap 44 having a reduced width.
- the line of weakness 36 is closed, i.e., has no extremity.
- a trajectory of the line of weakness 36 may be different.
- the line of weakness 36 may be open, i.e., has extremities not connecting to one another.
- a hinge 102 connects two points of the line of weakness 36 .
- the line of weakness 36 may be prolonged towards the distal fastener 84 such that the force applied by the spring 44 is able to cause failure of the aluminum alloy 62 in a portion 112 of the line of weakness 36 , but only able to bend (i.e., not cause failure of) the aluminum alloy 62 in a remaining portion 114 of the weakness line 36 .
- the remaining portion 114 of the line of weakness 36 acts as the hinge 102 .
- the spring 40 , the fasteners 82 , 84 and the frangible portion 34 may be configured in various ways.
- the button 30 may not be in-line with the fasteners 82 , 84 , but rather offset (e.g., decentered) such that it is closer to the rim 92 of the lid 12 than if it were at a center of the lid 12 , and the shape of the frangible portion 34 may change accordingly.
- the button 30 is offset (e.g., decentered) and beside the fasteners 82 , 84 (i.e., not between the fasteners 82 , 84 such that it does not intersect an imaginary straight line interconnecting the fasteners 82 , 84 ).
- the line of weakness 36 traces a hook 124 beside the button 30 and ends between the button 30 and the distal fastener 84 , such that the line of weakness 36 is open and the frangible portion 34 comprises a hinge 102 .
- the button 30 is centered and between the fasteners 82 , 84 such that it intersects an imaginary straight line interconnecting the fasteners 82 , 84 .
- the line of weakness 36 traces a hook 124 beside the button 30 and ends between the button 30 and the distal fastener 84 , such that the line of weakness 36 is open and the frangible portion 34 comprises a hinge 102 .
- the button 30 is beside the fasteners 82 , 84 (i.e., not between fasteners 82 , 84 such that it does not intersect an imaginary straight line interconnecting the fasteners 82 , 84 ) and adjacent to the proximal fastener 82 .
- the button 30 and the proximal fastener 82 are also adjacent to the rim 92 .

Provisional Patent Application 62/642,862 filed on Mar. 14, 2018 and incorporated by reference herein. - This disclosure generally relates to beverage cans and, more particularly, to lids (which may sometimes also be referred to as “ends”) of beverage cans.
- Opening mechanisms of beverage cans, which hold drinkable liquids such as carbonated beverages (e.g., soft drinks, sparkling water, etc.), alcoholic beverages (e.g., beer), juices, etc., have evolved over time.
- While various designs have been contemplated, they may present certain drawbacks. For example, lids (sometimes a.k.a. “ends”) of beverage cans with removable flaps and pushbuttons exist but typically require both hands to operate their opening mechanism, which sometimes fails, detaches and is thrown away, creating dangerous debris and often reducing recyclability of the beverage cans. Also, beverage cans having lids with levers and hinged flaps exist, but normally require both hands to operate their opening mechanism.

The beverage can 10 is a metal container configured to hold a drinkable liquid, such as a carbonated beverage (e.g., a soft drink, sparkling water, etc.), an alcoholic beverage (e.g., beer), a juice, an energy drink, a tea, or any other suitable beverage. The beverage can 10 comprises abody 13 that contains the drinkable liquid and a lid 12 (sometimes also referred to as an “end”) that is openable by a user to drink the drinkable liquid, such as by drinking it directly from the beverage can 10 or by pouring it into a glass, cup or other drinking vessel from which it is then drank. - As further discussed later, in this embodiment, the
lid 12 of the beverage can 10 is designed to facilitate its use, such as, for example, by being openable intuitively, with a single hand, and through spring-loading. Also, the beverage can 10, including thelid 12, may be manufactured more efficiently. - In this embodiment, the
lid 12 of the beverage can 10 comprises anouter side 14, aninner side 16, and anopening system 18 to create a pouringopening 20 to pour the drinkable liquid from the beverage can 10, either into the user's mouth or into a glass, cup or other drinking vessel from which the drinkable liquid is then drank. Thelid 12 comprises a base 50 underlying itsouter side 14 and itsinner side 16. Theouter side 14 of thelid 12 comprises anouter surface 53 of thebase 50, while theinner side 16 of thelid 12 comprises aninner surface 52 of thebase 50. - The
opening system 18 comprises anactuator 22 that is part of theouter side 14 of thelid 12 and manually operable to initiate creation of the pouringopening 20. That is, theactuator 22 is configured to be manually operated by the user to start creating the pouringopening 20. In this example, theactuator 22 allows the beverage can 10 to be opened with a single one of the user's hands, i.e., allows one-hand opening. - In this embodiment, the
actuator 22 comprises abutton 30 manually pressable upon to initiate creation of the pouringopening 20. When the beverage can 10 is to be opened, the user's thumb can be placed onto and press upon thebutton 30 to initiate creation of the pouringopening 20. - Notably, in this embodiment, the
lid 12 is configured to create the pouringopening 20 in response to only thebutton 30 being manually pressed upon. Thus, thelid 20 is configured to create the pouringopening 20 without manually applying force on thelid 20 other than manually pressing upon thebutton 30. That is, no other manual pressing or other manual force has to be exerted on thelid 12 to start creating the pouringopening 20. In particular, in this example, thelid 12 is configured to create the pouringopening 20 without any other button being manually pressed upon. This facilitates and simplifies opening of the beverage can 10. In this regard, in this example, theouter side 14 of thelid 12 is free of (i.e., without) any other button manually pressable upon to open the beverage can 10 elsewhere than at the pouringopening 20. For instance, theouter side 14 of thelid 12 is free of any button manually pressable upon to create a vent opening or any other opening spaced from the pouringopening 20. - More particularly, in this embodiment, the
button 30 projects from theouter surface 53 of thebase 50 of thelid 12. In this example, a height Hb of thebutton 30 is greater than a thickness TL of the base 50 (i.e., a thickness of thelid 12 from theouter surface 53 to the inner surface 52). In cases where it varies such as in this embodiment, the thickness TL of the base 50 can be taken as an average thickness of thebase 50. For instance, in some embodiments, a ratio of the height Hb of thebutton 30 over the thickness TL of the base 50 may be at least 2, in some cases at least 2.5, in some cases at least 3, and in some cases even more. - In this example, the
lid 12 comprises afrangible portion 34 configured to break to create the pouringopening 20. When thebutton 30 is manually pressed upon (e.g., by the user's thumb), a tear is initiated at thefrangible portion 34 and propagates to start creating the pouringopening 20. More particularly, in this example, thefrangible portion 34 comprises a line ofweakness 36 defining a contour of the pouringopening 20. The tear propagates on thelid 12 by following the line ofweakness 36. In this case, thefrangible portion 34 is a scored portion such that the line ofweakness 36 is a score line. - For example, in some embodiments, a ratio of a reduced thickness TSR of the
base 50 of thelid 12 at the line ofweakness 36 over a non-reduced thickness TSG of thebase 50 outside of the line ofweakness 36 may be no more than 0.2, in some cases no more than 0.1, in some cases no more than 0.05, and in some cases even less. For instance, in some embodiments, the reduced thickness of TSR of thelid 12 at the line ofweakness 36 may be no more than 0.5 mm, in some cases no more than 0.15 mm, in some cases no more than 0.05 mm, and in some cases even less. - In this embodiment, the
opening system 18 comprises aspring 40 to assist in opening the beverage can 10. It may thus be viewed as being spring-loaded. More particularly, in this embodiment, thespring 40 is part of theinner side 16 of thelid 12 and configured to enlarge the pouringopening 20 after theactuator 22 is manually operated. Accordingly, in this example, thespring 40 is configured to enlarge the pouringopening 20 after thebutton 30 is manually pressed upon. A spring force exerted by thespring 40 therefore helps to create the pouringopening 20, thereby facilitating opening of the beverage can 10. For instance, thespring 40 may be such that the beverage can 10 is effectively “self-opening” after thebutton 30 is manually pressed upon. - More particularly, in this embodiment, the
spring 40 is configured to retract aflap 44 into an interior 46 of the beverage can 10 to enlarge the pouringopening 20 after thebutton 30 is manually pressed upon. Thespring 40 is connected to thebase 50. In this example, thespring 40 projects from theinner surface 52 of the base 50 into the interior 46 of the beverage can 10. - In this embodiment, the
spring 40 includes aproximal extremity 72 and adistal extremity 74 that are connected to thebase 50 of thelid 12 adjacent to theinner surface 52. More specifically, in this embodiment, theproximal extremity 72 of thespring 40 is fastened to theflap 44, thedistal extremity 74 of thespring 40 is fastened to an anchoringportion 51 of the base 50 spaced from theflap 44, and theextremities spring 40 are substantially parallel and collinear to one another. Thespring 40 is curved in theinterior 46 of the beverage can 10. In this example, thespring 40 has acurved portion 76 and alinear portion 78 between itsextremities curved portion 76 has a curved shape which may be a circular shape, an ellipsoidal shape, or any suitable curved or bent shape. In this case, the curved portion 71 is such that thespring 40 is generally U-shaped. Thecurved portion 76 of thespring 40 extends from thedistal extremity 74 of thespring 40 in a rearward direction while projecting from theinner surface 52 into the interior 46 of the beverage can 10, before extending in a forward direction and back towards theinner surface 52. Thelinear portion 78 of thespring 40 connects thecurved portion 76 to theproximal extremity 72 of thespring 40. Thespring 40 may be shaped in any other suitable way in other embodiments. - The
spring 40 has a rest position wherein itsextremities spring 40 is fastened to theflap 44 and to thebase 52, theextremities spring 40 applies the spring force pulling on theflap 44 towards the interior 46 of the beverage can 10 and pushing on the anchoringportion 51 of the base 50 in an opposite direction. - More particularly, in this embodiment, the
spring 40 is fastened to theflap 44 by aproximal fastener 82 and to the anchoringportion 51 of the base 50 by adistal fastener 84. In this example, thefasteners extremities spring 40 to theflap 44 and to the anchoringportion 51 of thebase 50. Theproximal fastener 82 extends into anaperture 87 of theproximal extremity 72 of thespring 40 and creates adepression 86 at theouter side 14 of thelid 12. Thedistal fastener 84 extends into anaperture 89 of thedistal extremity 74 of thespring 40 creates adepression 85 at theouter side 14 of thelid 12. Each of theapertures spring 40 may be manufactured before thefasteners apertures fasteners apertures spring 40. In this case, thebutton 30 is disposed beside thefasteners 82, 84 (i.e., not between thefasteners fasteners 82, 84). Thebutton 30 is adjacent to theproximal fastener 82. - In this embodiment, the
button 30 is located on thefrangible portion 34 of thelid 12, such that thebutton 30 is configured to enter inside the beverage can 10 when manually pressed upon. More particularly, in this embodiment, thebutton 30 is part of theflap 44. Thebutton 30 is located near the line ofweakness 36 of thefrangible portion 34. After thebutton 30 is manually pushed upon and the pouringopening 20 starts to be created, anarea 67 of the pouringopening 20 where thebutton 30 was before thebutton 30 was pushed upon allows gas exchange between the interior 46 of the beverage can 10 and outside the beverage can 10 when the drinkable liquid is being poured. - In this example, the
lid 12 comprises arim 92 disposed at aperiphery 90 of thelid 12 and projecting upwardly from thebase 50 of thelid 12. In this embodiment, therim 92 is integrally formed with thebase 50 oflid 12. Alternatively, in other embodiments, therim 92 can be distinct from and fastened to thebase 50 of thelid 12 during manufacturing of the beverage can 10. - The
lid 12 may comprise one or more metallic materials and/or any other suitable material. In this embodiment, thelid 12, including itsbase 50, itsbutton 30 and itsspring 40, is at least partly (i.e., partly or entirely) made of aluminum. Thus, each of thebase 50, thebutton 30 and thespring 40 includes part of the aluminum of thelid 12. More particularly, in this embodiment, thelid 12 is at least mostly (i.e., mostly or entirely) made of aluminum. In this case, thelid 12 is entirely made of aluminum. This may help for recycling of thelid 12. Accordingly, in this example, thelid 12 is entirely recyclable. - In this embodiment, a
metallic material 60 of thespring 40 is different from ametallic material 62 of thebase 50. More specifically, in this embodiment, themetallic material 60 is an aluminum alloy of thespring 40 and themetallic material 62 is an aluminum alloy of the base 50 which is different from thealuminum alloy 60 of thespring 40. - In this example, the
aluminum alloy 60 of thespring 40 is stronger than thealuminum alloy 62 of thebase 50. For instance, in some embodiments, a ratio of a tensile strength of thealuminum alloy 60 of thespring 40 over a tensile strength of thealuminum alloy 62 of the base 50 may be at least 1, in some cases at least 2, in some cases at least 3 and in some cases even more. In this embodiment, thealuminum alloy 60 of thespring 40 is aluminum alloy 7075-T6, while thealuminum alloy 62 of thebase 50 is aluminum alloy 5182. Any other suitable aluminum alloys may be used in other embodiments. - The spring force exerted by the
spring 40 is sufficient to enlarge the pouringopening 20 once initiated by manually pressing upon thebutton 30. Under the spring force, thespring 40 pulls on theflap 44 to continue tearing thelid 20 and enlarge the pouringopening 20. For example, in some embodiments, the spring force exerted by thespring 40 may be at least 30 N, in some cases at least 40 N, in some cases at least 60 N, and in some cases even more. - The spring force exerted by the
spring 40 may also depend on an internal pressure of the beverage can 10 before it is open as the spring force and the internal pressure generally work against one another. For instance, the higher the internal pressure of the beverage can 10 is, the higher the spring force can be without causing failure of thefrangible portion 34 without thebutton 30 being manually pressed upon. In some cases, the spring force may be opposed by the internal pressure of the beverage can 10 to counter a tendency of thespring 40 to pull downwards and inwardly deflect (e.g., bow) thebase 50 of thelid 12. For example, in some embodiments, a ratio of the spring force exerted by thespring 40 over the internal pressure of the beverage can 10 may be between 80 N/MPa and 105 N/MPa, in some cases between 105 and 130 N/MPa, and in some cases about 105 N/MPa. - A cross-sectional area of the pouring
opening 20, which is normal to a longitudinal direction of the beverage can 10, is suitable for drinking or otherwise pouring the drinkable liquid and comparable to existing beverage cans. For example, in some embodiments, a ratio of the cross-sectional area of the pouringopening 20 over a cross-sectional area of thelid 12 normal to the longitudinal direction of the beverage can is at least 0.1, in some cases at least 0.15, in some cases at least 0.2, and in some cases even more. For instance, in some embodiments, the cross-sectional area of the pouringopening 20 may be between 2 cm2 and 8 cm2, in some cases between 2 cm2 and 4 cm2, and in some cases about 2.8 cm2. - In this embodiment, the cross-sectional area of the pouring
opening 20 is greater than a cross-sectional area of thebutton 30 normal to the longitudinal direction of the beverage can 10. In other words, the pouringopening 20 is larger than thebutton 30. For example, in some embodiments, a ratio of the cross-sectional area of the pouringopening 20 over the cross-sectional area of thebutton 30 may be at least 2, in some cases at least 4, in some cases at least 6, and in some cases even more. - The pouring
opening 20 may have any suitable shape. In this embodiment, the pouringopening 20 is noncircular. More particularly, in this embodiment, the pouringopening 20 is oblong. In this example, the pouringopening 20 is generally kidney-shaped. - The beverage can 10, including the
lid 12, may be manufactured in any suitable way. In this embodiment, thelid 12 is manufactured by pressing, using sheets of aluminum alloy. Thelid 12 may be pressed once, or it may be manufactured by being pressed several times. For example, in some embodiments, a first pressing may cut the periphery of thelid 12 from a sheet of aluminum alloy, then a second pressing may apply a thread of the lid 12 (e.g., thebutton 30, the line ofweakness 36, etc.), then a third pressing may form theintegral rivets extremities spring 40, theflap 44 and the anchoringportion 51 of thebase 50. A manufacturing process for thelid 12 may comprise one or more operations other than pressing (e.g., water jet cutting, water jet surfacing, etc.). Thelid 12 may be seamed to thebody 13 of the beverage can 10 in a seaming process comprising one or more steps involving a seaming chuck and a seaming roll to create a mechanical interlock between thelid 12 and thebody 13 of the beverage can 10. A compound may be used in a seam between thelid 12 and thebody 13 of the beverage can 10 to further seal thelid 12 with thebody 13 of the beverage can 10, thus preventing gas or liquid to get through. - In use, when the
button 30 is manually pressed upon (e.g., by the user's thumb), a stress is applied on thelid 12 near thefrangible portion 34, which creates stress concentration causing initial failure of thealuminum alloy 62 of thelid 12 on a portion of the line ofweakness 36. This initial failure weakens thefrangible portion 34 of thelid 12 and thespring 40 creates further stress concentration on the weakenedfrangible portion 34, at the line ofweakness 36, near the initial failure. Additionally, the initial failure allows gas exchange between the interior 46 of the beverage can 10 and an environment of the beverage can 10, thus allowing the internal pressure, which works against thespring 40, to drop. This combination of events causes a propagation of the initial failure through thefrangible portion 34 of thelid 12 along the line ofweakness 36. When the failure has propagated through the whole line ofweakness 36 such that theflap 44 is completely detached from thebase 50, thespring 40 returns to its rest position, causing theflap 44 to move towards the interior 46 of the beverage can 10 and creating the pouringopening 12. - In this embodiment, the
lid 12 is configured such that another beverage can is stackable on the beverage can 10 without interference from thebutton 30. For example, in this embodiment, therim 92 of thelid 12 extends at least as high as thebutton 30. In this case, therim 92 of thelid 12 extends higher than thebutton 30. - The
lid 12, including itsopening system 18, may be implemented in various other ways in other embodiments. - For example, in some embodiments, the
frangible portion 34 of thelid 12, including its line ofweakness 36, may have various other shapes. - As shown in
FIGS. 7 to 11 , in some embodiments, thebutton 30 is between thefasteners fasteners button 30 is located near the line ofweakness 36 of thefrangible portion 34 and is connected to a remaining portion of theflap 44 by aportion 94 of theflap 44 having a reduced width. The line ofweakness 36 is closed, i.e., has no extremity. - As shown in
FIGS. 12 and 13 , in some embodiments, a trajectory of the line ofweakness 36 may be different. For example, in some embodiments, the line ofweakness 36 may be open, i.e., has extremities not connecting to one another. In this example, ahinge 102 connects two points of the line ofweakness 36. When the beverage can 10 is opened, theflap 44 is not completely detached from thebase 50, as thehinge 102 maintains connection of theflap 44 to thebase 50. - As shown in
FIGS. 14 and 15 , in some embodiments, the line ofweakness 36 may be prolonged towards thedistal fastener 84 such that the force applied by thespring 44 is able to cause failure of thealuminum alloy 62 in aportion 112 of the line ofweakness 36, but only able to bend (i.e., not cause failure of) thealuminum alloy 62 in a remainingportion 114 of theweakness line 36. In this example, the remainingportion 114 of the line ofweakness 36 acts as thehinge 102. - The
spring 40, thefasteners frangible portion 34 may be configured in various ways. For example, in some embodiments, thebutton 30 may not be in-line with thefasteners rim 92 of thelid 12 than if it were at a center of thelid 12, and the shape of thefrangible portion 34 may change accordingly. - As shown in
FIG. 16 , in some embodiments, thebutton 30 is offset (e.g., decentered) and beside thefasteners 82, 84 (i.e., not between thefasteners fasteners 82, 84). The line ofweakness 36 traces a hook 124 beside thebutton 30 and ends between thebutton 30 and thedistal fastener 84, such that the line ofweakness 36 is open and thefrangible portion 34 comprises ahinge 102. - As shown in
FIG. 17 , in some embodiments, thebutton 30 is centered and between thefasteners fasteners weakness 36 traces a hook 124 beside thebutton 30 and ends between thebutton 30 and thedistal fastener 84, such that the line ofweakness 36 is open and thefrangible portion 34 comprises ahinge 102. - As shown in
FIG. 18 , in some embodiments, thebutton 30 is beside thefasteners 82, 84 (i.e., not betweenfasteners fasteners 82, 84) and adjacent to theproximal fastener 82. Thebutton 30 and theproximal fastener 82 are also adjacent to therim 92. The line ofweakness 36 encloses thebutton 30 and theproximal fastener 82 and has two extremities adjacent to thedistal fastener 84, creating ahinge 102 substantially perpendicular to the imaginary straight line betweenfasteners - As shown in
FIG. 19 , in some embodiments, thebutton 30 is offset (e.g., decentered) and between thefasteners fasteners weakness 36 traces a hook 124 beside thebutton 30 and ends between thebutton 30 and thedistal fastener 84, such that the line ofweakness 36 is open and thefrangible portion 34 comprises ahinge 102. Thehinge 102 is substantially perpendicular to the imaginary straight line betweenfasteners - In some embodiments, as shown in
FIGS. 20 to 23 , thefrangible portion 34 may comprise score lines 132 1-132 s defining flap sections 134 1-134 f facilitating opening of the beverage can 10. The thickness TL of thelid 12 at the score lines 132 1-132 s is reduced. Thus, the score lines 132 1-132 s allow thefrangible portion 34 to bend under stress. During opening, this increases stress concentration around the failure and the line ofweakness 36, and accordingly the spring force exerted by thespring 40 may be reduced to pull on theflap 44. - For instance, in some embodiments, a ratio of the reduced thickness TSR of the
base 50 of thelid 12 at the score lines 132 1-132 s over the non-reduced thickness TSG of thebase 50 outside of the score lines 132 1-132 s and the line ofweakness 36 may be no more than 0.2, in some cases no more than 0.1, in some cases no more than 0.05, and in some cases even less. For instance, in some embodiments, the thickness of TL of thelid 12 at the score lines 132 1-132 s may be no more than 0.2, in some cases no more than 0.1, in some cases no more than 0.05, and in some cases even less. - The score lines 132 1-132 s may have any suitable shape. For example, as shown in
FIGS. 20 and 23 , in some embodiments, the score lines 132 1-132 s may be straight and generally disposed radially relative to thebutton 30. As another example, as shown inFIG. 22 , in other embodiments, the score lines 132 1-132 s may be curved and generally define a spiral pattern. - The
spring 40 may be implemented in any other suitable way (e.g., have any other suitable shape, include any other suitable component, and/or be made of any other suitable material) in other embodiments. - For example, in some embodiments, as shown in
FIG. 24 , thespring 40 may not be in-line with thefasteners spring 40 to thelid 20, reduce cost, and/or increase efficiency of theopening mechanism 18. - As another example, in some embodiments, as shown in
FIG. 25 , thecurved portion 76 of thespring 40 may extend from theproximal extremity 72 in the forward direction while projecting from theinner surface 52 into the interior 46 of the beverage can 10, before extending in the rearward direction and projecting from theinterior 46 of the beverage can 10 towards theinner surface 52. Thelinear portion 78 of thespring 40 connects thecurved portion 76 to thedistal extremity 74 of thespring 40. - In some embodiments, as shown in
FIG. 26 , thecurved portion 76 of thespring 40 comprises a bend and extends from thedistal extremity 74 in the forward direction by projecting less from theinner surface 52 into the interior 46 of the beverage can 10. - In some embodiments, as shown in
FIG. 27 , thespring 40 may comprises a plurality ofcurved portions linear portion 78 therebetween. In this example, thecurved portion 76 1 extends from thedistal extremity 74 in the forward direction while projecting from theinner surface 52 into the interior 46 of the beverage can 10, thelinear portion 78 connects thecurved portion 76 1 to thecurved portion 76 2 which projects from theinterior 46 of the beverage can 10 towards theinner surface 52 and connects to theproximal extremity 72. - In some embodiments, as shown in
FIG. 28 , thespring 40 may comprise a plurality of curved portions 76 1-76 c that alternate convexly and concavely. In this example, thespring 40 extends from thedistal extremity 74 in the forward direction and the curved portions 76 1-76 c project towards and away theinner surface 52 to finally connect to theproximal extremity 72. This may allow thespring 40 to have a greater length, and thus allow a deflection of thespring 40 to be greater, and/or the spring force exerted on theflap 44 to be greater. - The
button 30 may have any other suitable shape in other embodiments. For example, in some embodiments, as shown inFIG. 45 , thebutton 30 may be generally triangular, such as a Reuleaux triangle. - In some embodiments, as shown in
FIGS. 46 and 47 , thebutton 30 may be connected to thespring 40 by therivet 82 that intersects thebutton 30 and thespring 40, and the line ofweakness 36 may be shaped to follow a majority of a perimeter of thebutton 30. In some examples, as shown inFIG. 46 , the line ofweakness 36 may be shaped such that thebutton 30 can be manually pressed upon closer to an edge of the beverage can 10. In some examples, as shown inFIG. 47 , the line ofweakness 36 may be shaped such that thebutton 30 can be manually pressed upon closer to a center of the beverage can 10. - With additional reference to
FIGS. 29 to 32 , in some embodiments, the beverage can 10 may comprise a spring-force compensator 210 configured to compensate for the spring force exerted by thespring 40, which in some cases may create a tendency of thespring 40 to pull downwards and inwardly deflect (e.g., bow) thebase 50 of thelid 12 and maintain a cylindrical shape of the beverage can 10. The spring-force compensator 210, which may sometimes be referred to as a “spring retainer”, generally works against thespring 40 and applies on thebase 50 of thelid 12 and/or thespring 40 an opposite force nullifying the force applied by thespring 40 on thelid 12 when thespring 40 is installed under thebase 50 of thelid 12. When thebutton 30 is manually pressed upon, the spring-force compensator 210 is disabled in a hair-trigger way, further facilitating the opening of the beverage can 10. - In this embodiment, the spring-
force compensator 210 is disposed inside the beverage can 10. More specifically, in this embodiment, the spring-force compensator 210 is implemented as a container (e.g., a cartridge) that contains thespring 40. More particularly, in this embodiment, the spring-force compensator 210 may include asheet 212 of material 64 which is folded around thespring 40 and attached to theinner surface 52. In this example, the material 64 is an aluminum alloy. - In particular, in this embodiment, the
sheet 212 comprises aretaining wall 214, abottom wall 216, arear wall 218 opposite to theretaining wall 214, and atop wall 220 opposite to thebottom wall 216. - The retaining
wall 216 is attached to alatch 240 retaining thespring 40 by apivot 244 and by asupport 242. The retainingwall 216 also comprises arest area 230 where theproximal extremity 72 of thespring 40 rests. The retainingwall 216 further comprises lines of weakness 232 1, 232 2 andchannels panels button 30 is manually pushed upon, a load is applied on thelatch 240 and/or on therest area 230, thereby causing failure of thesupport 242, allowing thelatch 240 to rotate relative to theretaining wall 216 and releasing thespring 40. During this process, the lines of weakness 232 1, 232 2 may allow theretaining wall 216 to bend and thechannels panels support 242. - The
bottom wall 216 and thewall flap 218 ensure structural integrity of thespring compensator 210 and connect theretaining wall 214 to thetop wall 220. Thetop wall 220 secures thespring compensator 210 to theinner surface 52 of thelid 12 by any suitable means, such as, for example, by being fastened to thelid 12. - The spring-
force compensator 210 may be implemented in any other suitable way in other embodiments. For example, in some embodiments, as shown inFIGS. 46 to 49 , thespring retainer 210 may comprise retainingflaps portion 250 of thespring 40 until thebutton 30 is manually pressed upon, thereby causing thespring retainer 210 to release theportion 250 of thespring 40. In this embodiment, theflaps portion 250 of thespring 40. Theflaps latch 240. Thespring retainer 210 may be formed integrally with a remainder of thespring 40, such as by punching and folding the flaps 223 1, 223 2, and bending the remainder of thespring 40, Theportion 250 of thespring 40 may be lifted to engage and be held by the flaps 223 1, 223 2 of thespring retainer 210, and thespring 40 may then be attached to thebase 50 of thelid 12 using therivets - With additional reference to
FIGS. 33A to 33D , in some embodiments, the beverage can 10 may be provided with astraightener 260 outside of the beverage can 10 to straighten thebase 50 of the lid 12 (i.e., make the base 50 more straight than without the straightener 260) and maintain the circular shape of thelid 12 during assembly of thelid 12 to the beverage can 10 by opposing the tendency of thespring 40 to pull downwards and inwardly deflect (e.g., bow) thebase 50 of thespring 40. Thestraightener 260 generally works against thespring 40 and applies on thelid 12 an opposite force nullifying the force applied by thespring 40 on thelid 12 when thespring 40 is installed under thebase 50 of thelid 12, to maintain a circular or pre-determined shape of thelid 12 during manufacturing, before thelid 12 is attached to thebody 13 of the beverage can 10 with a sealingmachine 79. For instance, the sealingmachine 79 may comprise apress 81 that can engage and cooperate with thestraightener 260 to seal thelid 12 to thebody 13 of the beverage can 10. After thelid 12 is attached to thebody 13, thestraightener 260 is removed from the beverage can 10 and can be recycled or reused. Alternatively or additionally, thestraightener 260 can be part of the sealingmachine 79. - In this embodiment, the
straightener 260 comprises asupport disc 261. In this example, thesupport disc 261 comprises a void 267 (e.g., a recess or a hole) to receive thebutton 30 of thelid 12. Also, in this example, thesupport disc 261 has a circular shape and comprises no thread. Alternatively, in some embodiments, thesupport disc 261 comprises a thread facilitating the installation and removal of thesupport disc 261 on thelid 12. - The
support disc 261 has rigidity and a thickness TD allowing thelid 12 to remain circular when thespring 40 is attached to the remainder of thelid 12. To this end, thesupport disc 261 comprises a material 262 which can be the same as the material of thespring 40. Alternatively, thematerial 262 of thesupport disc 261 may be different and, in some cases, more rigid than thematerial 60 of the spring 40 (e.g., steel). - Also, the
material 262 of thesupport disc 261 may have magnetic capabilities facilitating the installation and removal of thesupport disc 261 for thelid 12 during manufacturing and/or before use (e.g., with thepress 81 of the sealing machine 79). - When the
lid 12 is attached to thebody 13 of the beverage can 10, thelid 12 and thebody 13 are pressed and folded one over the other, thus creating therim 92. During this process, thesupport disc 261 is on thelid 12 and refrains therim 92 that is being formed to have a non-desired shape. - In other embodiments, the
support disc 261 may be hollow and permanent, i.e., thesupport disc 260 may have an hollow shape comprising a circular aperture and be installed permanently on the beverage can 10 and still be in place while thelid 12 of the beverage can 10 is being opened and the drinkable liquid is being poured. - With additional reference to
FIGS. 34 and 35 , in some embodiments, the beverage can 10 may comprises alever 300 configured to allow the user to apply a compressive force on thebutton 30 more easily. In this embodiment, thelever 300 is a reverse-action lever that comprises afirst lever member 312 and asecond lever member 314. - The
first lever member 312 comprises anouter end 320 adjoining therim 92 of thelid 12. In some cases, theouter end 320 of thefirst lever member 312 comprises apivot 330 where thefirst lever member 312 is pivotably connected to asupport 332. Optionally, the support 324 rests on adepression 316 of thelid 30, to allow the user to more easily grab theouter end 320 of thefirst lever member 312. Thefirst lever member 312 further comprises aninner end 322. Theinner end 322 of thefirst lever member 312 comprises apivot 352 where thefirst lever 312 is pivotably connected to amount 350. Theinner end 322 also comprises asurface 352 contacting thesecond lever member 314. - The
mount 350 is pivotably attached to thefirst lever member 312 by thepivot 352 and to thesecond lever member 314 by apivot 354. Themount 350 is further secured to thelid 12 by any suitable means, for example by being fastened to an outer surface of thelid 12. - The
second lever member 314 comprises aninner end 360. Theinner end 360 of thesecond lever member 314 comprises a surface 372 contacting thesurface 352 of thefirst lever member 312. Thesecond lever 314 further comprises anouter end 362. Theouter end 362 comprises anedge 380 which adjoins thebutton 30 and which is in contact with the outer surface of thelid 12. - When the
support 332 of thefirst lever member 312 is rotated such that it does not support theouter end 320 of thefirst lever member 312, and subsequently theouter end 320 of thefirst lever member 312 is pushed upon, thefirst lever member 312 rotates and thesurface 352 of thefirst lever member 312 pushes the surface 372 of thesecond lever member 314, thus rotating thesecond lever member 314 such that theedge 380 of thesecond lever member 314 is pushed against the outer surface of thelid 12. In particular, theedge 380 of thesecond lever 314 is pushed against the outer surface of thelid 12 by a force which is larger than the force pushing upon theouter end 320 of thefirst lever member 312. For example, in some embodiments, the ratio of the force pushing theedge 380 of thesecond lever member 314 against the outer surface of thelid 12 over the force pushing upon theouter end 320 of thefirst lever member 312 may be at least 2, in some cases at least 4, in some cases at least 6, in some cases even more. - The
lever 300 may be implemented in any other suitable way in other embodiments (e.g., may comprise a single lever member). - With reference to
FIGS. 36 to 44 , in some embodiments, at least part of thelid 12 may be formed integrally with at least part of thebody 13 of the beverage can 10, and/or the beverage can 10 may be manufactured and filled upside down. - In this embodiment, a
precursor 75 for the beverage can 10 comprises thelid 12 that is at least partly formed integrally with apart 55 of the beverage can'sbody 13. More particularly, in this embodiment, aportion 66 of thelid 12, which includes thebase 50, thebutton 30, and thefrangible portion 34 to create theflap 44 of thelid 12, is formed integrally with thepart 55 of the beverage can'sbody 13, i.e., this “integrally-formed”portion 66 of thelid 12 comprises thebase 50, thebutton 30, thefrangible portion 34, and theflap 44 of thelid 12 and is an integral component of the beverage can'sbody 13 instead of made separately from and fastened to the beverage can'sbody 13. This may facilitate stacking, transporting and/or otherwise handling of the beverage can 10 including itslid 12 in some cases. This may also help to maintain thelid 12 in optimal shape under tension of thespring 40. - More particularly, in this embodiment, the
body 13 of the beverage can 10 comprises anend portion 57 and an uprightperipheral portion 59 that is formed integrally with and projects from theend portion 57, and the integrally-formedportion 66 of thelid 12 is integrally formed with theend portion 57 of the beverage can'sbody 13, i.e., the integrally-formedportion 66 of thelid 12 is part of theend portion 57 of the beverage can'sbody 13. Theend portion 57 of the beverage can'sbody 13 may be stronger and stiffer (e.g., thicker) than the uprightperipheral portion 59 of the beverage can'sbody 13, thereby being suitable for implementing thelid 12. - In this example, the
end portion 57 of the beverage can'sbody 13 including the integrally-formedportion 66 of thelid 12 is configured to constitute a top of the beverage can 10 in use, but may be located below a bottom of the beverage can 10 during manufacturing and filling of the beverage can 10, as further discussed below. - For instance, in this embodiment, the beverage can 10, including the
end portion 57 of itsbody 13 that comprises the integrally-formedportion 66 of thelid 12, may be manufactured as follows. - As shown in
FIG. 37 , aflat aluminum disc 70 or other suitable metallic material is provided to form the beverage can'sbody 13, including itsend portion 57 that comprises the integrally-formedportion 66 of thelid 12. For example, in some embodiments, theflat aluminum disc 70 may be like those currently used in bodies of beverage cans that are mass produced. - A
central region 73 of theflat aluminum disc 70 that will form thebutton 30 and thefrangible portion 34 of thelid 12 and support thespring 40 is thinned out. Thecentral region 73 is thus thinner than anadjacent region 45 of theflat aluminum disc 70. This may be done by pressing thecentral region 73 of theflat aluminum disc 70 to reduce its thickness. - Then, the
button 30, the score line defining the line ofweakness 36 of thefrangible portion 34 for theflap 44, and theintegral rivets central region 73 of theflat aluminum disc 70, as shown inFIGS. 38 to 40 . This may be done by punching or otherwise pressing on parts of the thinned-outcentral region 73 of theflat aluminum disc 70 that correspond to thebutton 30, the score line defining the line ofweakness 36 of thefrangible portion 34 for theflap 44, and theintegral rivets - The
aluminum disc 70, with thebutton 30, the score line defining the line ofweakness 36 of thefrangible portion 34 for theflap 44, and theintegral rivets central region 73 by cupping to form a cup-shapedpart 56 comprising theend portion 57 of the beverage can'sbody 13 which includes thelid 12. - In this embodiment, a
circular bend 80 is formed to reinforce thelid 12 that is part of theend portion 57 of the beverage can'sbody 13 and facilitate stacking of the beverage can 10 when filled. In this example, thecircular bend 80 creates acircular projection 83 projecting outwardly on theouter side 14 of thelid 12. Thecircular projection 83 acts as therim 92 of thelid 12 as discussed above, so that it extends at least as high as, and in this case higher than, thebutton 30 to facilitate stacking. - The
spring 40 is then mounted in tension to theend portion 57 of the beverage can'sbody 13 which includes thelid 12, as shown inFIG. 41 . In this example, this is done by placing thespring 40 and fastening it to thelid 12 via theintegral rivets - The upright
peripheral portion 59 of the beverage can'sbody 13 is then formed by drawing so that it is stretched out, as shown inFIGS. 42 and 43 . Because of presence of thespring 40, a drawing punch 77 (e.g., cylinder) may comprise a void 88 to receive and accommodate thespring 40 while stretching the uprightperipheral portion 59 of the beverage can'sbody 13. - Various steps in manufacturing the beverage can's
body 13, including itsend portion 57 that comprises the integrally-formedportion 66 of thelid 12, along with thespring 40 mounted to that integrally-formedportion 66 of thelid 12 may be performed using a forming apparatus that comprises an input to receive theflat aluminum disc 70 or other suitable metallic material and forming machinery, which comprises one or more machines (e.g., including punches, presses, dies, etc.), to make the beverage can 10. In some cases, the forming apparatus may reside in a single location. In other cases, respective parts (e.g., of the forming machinery) of the forming apparatus may reside in different locations. - The beverage can's
body 13 including itsend portion 57 that comprises the integrally-formedportion 66 of thelid 12, along with thespring 40 mounted to that integrally-formedportion 66 of thelid 12 may than proceed to be filled with the drinkable liquid, as shown inFIG. 44 . More particularly, in this example, the beverage can'sbody 13 may be filled by a filling device introducing the drinkable liquid through anopening 93 at a top of the beverage can'sbody 13 opposite to theend portion 57 of the beverage can'sbody 13 that comprises the integrally-formedportion 66 of thelid 12. Theopening 93 at the top of the beverage can'sbody 13 is located at the bottom of the beverage can 10. Thus, the beverage can 10 is filled upside down. - A
lid 95 is then mounted to the beverage can'sbody 13 and closes theopening 93 through which filling was done to complete the beverage can 10. Thelid 95 is configured to form the bottom of the beverage can 10 in use. Thelid 95 may be seamed to the beverage can'sbody 13 by a closing device (e.g., comprising a seaming chuck and a seaming roll to create a mechanical interlock between thelid 95 and the beverage can's body 13). A compound may be used in a seam between thelid 95 and the beverage can'sbody 13 to further seal thelid 95. - The beverage can 10 may then be rotated so that its
end portion 57 that comprises the integrally-formedportion 66 of thelid 12 is at its top and thelid 95 is at its bottom. - Certain additional elements that may be needed for operation of some embodiments have not been described or illustrated as they are assumed to be within the purview of those of ordinary skill in the art. Moreover, certain embodiments may be free of, may lack and/or may function without any element that is not specifically disclosed herein.
