Definitions

  • This invention relates to containers, and in particular to cans having a ring-pull opener, as defined hereinafter.
  • a ring-pull opener is normally provided in an end wall of a can, and has a manually-g ⁇ ppable ring member connected to the end wall by means of a rivet, often formed integrally with the end wall of the can.
  • a removable area of the end wall is circumscribed by a score-line extending part-way through the thickness of the material of the end wall, and the arrangement is such that the material of the end wall bound by the score-line may be removed by manipulating the ring member, so as to open the can.
  • Such an arrangement is referred to herein as a ring-pull opener of the kind described.
  • the ring member may be connected to the material of the end wall within the area bound by said score-line (the removable material) .
  • the ring member may be connected to the material of the end wall within the area bound by said score-line (the removable material) .
  • lifting of and pulling on the ring member breaks the removable material away from the remainder of the end wall along the score-line, so opening the end wall.
  • This arrangement results in the ring member, together with the removable material being separated from the can, once opened. People have tended to discard the ring member and removable material somewhat inconsiderately, and so an alternative subsequent design of ring-pull opener has been developed especially for drinks cans, in which the ring member is secured to the non-removable material of the end wall, adjacent the score-line defining the removable material.
  • the ring member includes a peripheral lever portion which projects beyond the fixing of the ring member to the end wall and overlies a part of the removable material; on lifting the ring member, the peripheral lever portion is pressed downwardly into engagement with the removable material and breaks that material away from the end wall, at least for the greater part of the length of the score-line.
  • ring member is used herein to refer to that member which is manipulated to open the can, irrespective of the actual shape or configuration of that member.
  • any significant increase m the number of parts, number of folds, amount of material folded, or other variables, may significantly increase the plurality of stations needed in the progression dies utilized in the production of the specific ring-pull openers, with a consequential increase m die cost, but, more importantly, in the production time for a single ring-pull opener.
  • these times are multiplied by the production rates specified above, and keeping m mind that these dies typically run 24 hours a day, 365 days a year (with the exception of down-time for repair and maintenance) , it will be appreciated that a fraction of a second increase in production time for a single ring-pull opener can result in an annual reduction of millions of ring-pull openers per progression die.
  • a novel and inventive structure of selectively reclosable ring-pull opener for use with a can of the type having a top wall, a base wall, and a cylindrical side wall joining said top and base walls together in sealed relation, with a score line in said top wall defining a movable region of material.
  • the movable region of the top wall material is movable between a first closed position, whereat it is integral with the top wall in sealing relation therewith, and an open position whereat the movable region of material is displaced from the first closed position to create an opening in the top wall.
  • the movable region of material is bounded by a non-movable region of material of the top wall.
  • the ring-pull opener of the invention is characterized by a unitary main body comprising a manually grippable ring portion extending above said top wall in acutely angled relation to said top wall to define a first operative plane relative to said top wall, a closure portion underlying said manually grippable ring portion and extending above said top wall in substantially parallel overlying relation to said top wall to define a second operative plane substantially parallel to said top wall, with the closure portion having a peripheral flange portion and a downwardly depending skirt portion of substantially the same plan outline and size as said opening.
  • the closure portion is solid at least within the area bounded by the skirt portion.
  • a tab portion extends downwardly from the ring portion to contact, in overlying relation, an upper surface of the peripheral flange portion of the closure portion.
  • a connecting nose portion extends in folded, connecting relation from a peripheral edge of the ring portion to an underlying peripheral edge of the closure portion.
  • a mounting means preferably in the form of a rivet, is affixed to the top wall and operatively passes through the tab portion and the upper surface area of the flange portion to movably mount the main body on the top wall of the can for upwardly directed, hinging movement of the manually grippable ring portion from the first operative plane toward the vertical, for coincident downward movement of the connecting nose portion into opening urging contact with the movable region of material of the top wall of the can, thereby to cause movement of the movable region from the first closed position to the open position, for rotatable movement of the main body in the second operative plane from a first position whereat the skirt portion is removed from overlying the perimeter of the opening, and a second position whereat the skirt portion is in overlying registered relation with the opening, and for downwardly directed, hinged movement of the closure portion below the second operative plane.
  • the peripheral flange portion is preferably continuous, and is shaped and dimensioned to overlie the perimeter of the opening in overlapping contacting relation to the non-movable region of top wall material, when the movable region of material has been moved to the open position as aforesaid, the main body has been rotatably moved to the second position, and the closure portion has been hingingly moved as aforesaid below the second operative plane to a fully inserted position, at which fully inserted position the closure portion substantially occludes the can opening.
  • the outer surface of the downwardly extending skirt portion is preferably provided with one or more laterally outwardly extending nibs adjacent the downward extent of the skirt portion, such that, when the skirt portion is, in the aforesaid fully inserted position, within the can opening, the nibs underlie the wall of the can and resist removal of the skirt portion from within the opening by way of yielding frictional contact with the wall of the can upon such removal .
  • a bead or film of sealing material is preferably provided at the area of the junction between the skirt portion and the peripheral flange portion to enhance the sealing between the peripheral flange portion, the skirt portion and the opening.
  • the presence of the closure portion need not affect the disposition of the ring-pull opener closely adjacent the general plane of the end wall of the can prior to the opening thereof, and so the stack ability of the cans, one on another, will not be affected.

  • a ring-pull opener 20 may be employed with a conventional metallic can 22, typically having a cylindrical side wall 24 and a base wall 25.
  • the can 22 may be a beverage can, or, for example, a can used to hold non-consumable liquids, such as, for example, motor oil or additives therefor.
  • the can will have a top wall 26 secured, for example, by conventional crimping, to the upper edge of the side wall 24.
  • the top wall 26, the base wall 25, and the cylindrical side wall 24 are joined together in sealed relation so as to contain, for example a carbonated beverage.
  • Such a drink can 22 may be made from relatively thin sheet steel or aluminum, appropriately treated, as is well known in the art, to prevent degradation or contamination of the contents.
  • a score line 36 being a line of weakness extending part-way through the thickness of the material of the top wall 26, is conventionally scribed on the top wall 26 of the can 22 to define a movable region of metal material 38 of the top wall 26, which region 38 is typically arcuate, and is displaceable from a first closed position (seen in Figures 1, 2 and 3B) whereat the movable region of material 38 is integral with the top wall 26 in sealing relation therewith, and an open position (seen in Figures 4A through 9C) whereat the movable region of material 38 is displaced from the first closed position, so as to create an opening 40 in the top wall 26, the movable region of material 38 being bounded by a non-movable region of material 42, which non-movable region of material 42 generally defines the remainder of the top wall 26.
  • the contents of the beverage can 22 can be emptied by a user through the opening 40, once said opening is created, in the manner described hereinbelow.
  • the ring-pull opener 22 is connected to the top wall 26 of the beverage can 22 by a mounting means positioned on the top wall 26 so as to provide for moveable attachment of the ring-pull opener 22 in a manner that will be described more fully below.
  • the mounting means is preferably a rivet 44 extending through apertures in both the top wall 26 and the ring-pull opener 22. Though in the drawings the rivet 44 is shown as a separate item, it is in fact possible to secure the ring-pull opener 22 to the top wall 26 by means of a rivet which is formed integrally with the material of the top wall 26, and which is deformed to hold the ring-pull member 22 in position, once fitted on to that rivet.
  • the ring-pull opener 20 includes and is characterized by a unitary main body 27, which is stamped from strip metal as it passes through a high speed progression die.
  • the unitary main body 27 is shown unfolded in Figure 3A, which main body 27 has a manually grippable ring portion 28 extending above the top wall 26 in acutely angled relation to the top wall 26 so as to define a first operative plane, designated by dashed line 30 of Figure 2, relative to the top wall 26.
  • the main body 27 further includes a closure portion 32 which, in the operative folded configura ions shown in all but Figure 3A of the drawings, underlies the manually grippable ring portion 28 and extends above the top wall 26 of the can 22 in substantially parallel overlying relation to the top wall 26, so as to define a second operative plane of motion substantially parallel to the top wall 26, which second operative plane is designated in Figure 2 by a dashed line having the reference numeral 33.
  • the closure portion 32 itself has a peripheral flange portion 34, which is preferably continuous, and a downwardly depending, preferably continuous, skirt portion 37 having substantially the same plan outline and size as the opening 40 of the can 22 so as to close fitted within the opening 40 as will become apparent as this description progresses .
  • the closure portion 32 essentially comprises the peripheral flange portion 34, the skirt portion 37 and an upper surface 48 of the closure member, which upper surface 48 is disposed at the lower most extent of the skirt portion 37, so as to define an embossment adapted to selectively occlude opening 40, as described more fully below.
  • the embossment so formed by the elements 34, 37, and 48 of the closure portion 32 is preferably tapered in its depth, with the deepest section on the outer edge furthest from the rivet 44, and the shallowest section towards the rivet 44, such taper being non-linear.
  • the main body 27 further comprises a tab portion 46, which is defined by a three-sided cut 45, and which, in the operatively folded configurations shown in all but Figure 3A, extends downwardly (ie. toward the top wall 26 of the can 22) to contact, in overlying relation, an upper surface 48 of said closure portion 32, which upper surface 48 is bounded by the inner extent of the skirt portion 37.
  • the downwardly depending skirt portion 27 has substantially the same plan outline and size as the opening 40 in the top wall 26, such that the closure portion 32, including the upper surface 48, and a corresponding parallel lower surface area 50, which lower surface 48 is bounded by the outer extent of the skirt portion 37, cause the closure portion 32 to be solid in the area bounded by the skirt portion, so as to thereby occlude the opening 40 of the can 22 as will appreciated as this description proceeds.
  • the main body 27 further comprises a connecting nose portion 54, which nose potion 54 extends in folded connecting relation from a peripheral edged 56 of the ring portion 28 to an underlying peripheral edge 58 of the closure portion 32.
  • the manually grippable ring portion 28 is preferably in the shape of an elongated rectangle, with a circular cut-out 52 positioned for gripping by a user adjacent the end of the grippable ring portion 28 disposed distal to the rivet 44 , and with the tab portion 46 preferably extending downwardly toward the upper surface 48 as aforesaid from an opposite other end of the ring portion 28.
  • the movable region of material 38 is of the same general plan shape and size as the closure portion 32 (with the peripheral flange portion 34 excluded) , and, with the main body 27 in its first position before opening of the can 22 (as illustrated in Figures 1, 2 and 3B) , the axis of symmetry of the movable region of material 38 is on the same line as the axis of symmetry of the main body 27, but on the other side of the rivet 44.
  • the connecting nose portion 54 thus partially overlies the movable region of material 38 defined by the score-line 36.
  • the connecting nose portion 54 is shaped and dimensioned to urgingly contact the movable region of material 38 so as to displace the movable region of material 38 from the first closed position to the second open position, as aforesaid, upon manual manipulation by a user of the grippable ring portion 28 about the rivet 44 in a generally upward direction away from the top wall 26 (see arrow Al of Figures 4A and 4B) .
  • the rivet 44 acts in this manner as a fulcrum to facilitate such manual manipulation.
  • the grippable ring portion 28 is lifted by a user gripping the circular cut-out 52, and thereafter moving the ring portion 28 in the direction of arrow Al of Figures 4A and 4B.
  • This action causes the connecting nose portion 54 to exert a downward pressure on the movable region of material 38, so shearing that region away from the remainder of the top wall 26, along the score line 36.
  • the movable region of material 38 is thus moved inwardly of the can 22 , as indicated by arrow A2 of Figures 4A and 4B, so opening it; but the movable region of material 38 normally hinges downwardly about one edge, as can be seen in Figures 4A. This may be assured by having a lesser depth of score toward the rivet side of edge 41.
  • the rivet 44 is affixed as aforesaid to the non-movable region 42 of the top wall 26 of the can 22, and operatively passes through an aperture 60 (see Figure 3A) in the tab portion 46.
  • the rivet 44 thereafter passes through an aligned, overfolded aperture 62 in the closure portion 32 to thereby movably mount the main body 27 on the top wall 26 of the can 22 for upwardly directed, hinged movement of the manually grippable ring portion 28 (as described in the previous paragraph) from the first operative plane 30 towards the vertical.
  • the attachment of the main body 27 by the rivet 44 in the manner shown also provides for rotatable movement of the main body
  • the closure portion 32 is moved by the user in the direction of arrow F (as shown in Figure 7B) so as to cause downwardly directed, hinged movement of the closure portion 32 about the rivet 44 to a fully inserted position below the second operative plane 33, as shown in Figures 8A - 8C.
  • the peripheral flange portion 34 of the closure portion 32 defines an area slightly greater than that of the opening 40, and for this reason it overlies the perimeter of the opening 40 in overlapping contacting relation with the non-movable region of material 42 when the main body 27 has been moved into the fully inserted position.
  • the peripheral flange portion 34 interacts with the perimeter of the opening 40 to form a stop means to prevent the closure portion from passing through the opening 40 into the interior of the can 22.
  • the closure portion 32 will, when positioned in the fully inserted position of Figures 8A, 8B and 8C, substantially occlude the opening 40.
  • such occlusion together with the overlying interaction of the peripheral flange portion 34 with the perimeter 68 area around the opening 40 (see Figures 9B and 9C) , will substantially seal the opening in the top wall 26.
  • the original quality of a beverage within the can 22, including carbonation can be substantially sustained, perhaps with refrigeration, for a considerable number of hours, or even days.
  • substantial resistance to spillage is also obtained.
  • the outer (ie., downwardly directed) surface 64 of the skirt portion 37 is preferably provided with two laterally outwarding extending nibs 66, positioned thereon such that, when the skirt portion 37 is in the fully inserted position within the opening 40, the two nibs 66 each underlie the perimeter 68 of the opening 40 in the top wall 26, so as to resist removal of the closure portion 32, including the skirt portion 37, from within the opening 40, due to yielding frictional contact of the nibs 66 with the perimeter edge 68. It is also preferable that all free edges of the main body 27, including that of the circular cut-out 52, be rolled over as shown In the Figures, so that no sharp edges are exposed to cut a user.
  • the peripheral flange portion 34 is also preferably provided, in the region above each of the nibs 66, with an upwardly angled, laterally extending wing member 70.
  • the purpose of the wing members 70 is twofold. In the first instance, the wing members 70 each provide a surface to facilitate gripping by a user when he/she wishes to re-open the can from the fully inserted position of the closure portion 32.
  • This action also causes the wings 70 to be squeezed toward one another, thereby to cause a slight concave contraction of the closure portion 32 about its centreline, which contraction in turn causes the nibs 66 to move inwards from their original position (as shown in solid outline in Figure 9B and in phantom outline in Figure 9C) to a squeezed position (shown in solid outline in Figure 9C) .
  • the closure portion can then be upwardly removed from the fully inserted position, to a position equivalent to that shown in Figures 7A and 7B, and thereafter rotated 180 degrees for re ⁇ seating in the recess 72 at its original position (equivalent to that shown in Figures 5A and 5B) .
  • the process of opening and closing the can be repeated in an analogous manner, as required.
  • a bead 74 of a conventional sealing compound is preferably disposed at the junction of the underside of the peripheral flange portion 34 and the skirt portion 37, to act as a gasket to assist in the making of a seal between the closure portion 32 and the perimeter of the opening 40 in the top wall 26 of the can 22.
  • the top wall 26 is preferably provided with a recess 72, to accommodate the closure portion 32 when the ring-pull member 20 is in the first position illustrated in Figures 1, 2 and 3B.
  • the provision of a recess 72 allows the closure portion 32 to lie lower with respect to the top wall 26 to facilitate stacking of cans 22 on top of one another.
  • the recess 72 preferably extends around the perimeter 68 of the opening 40 in a conventional manner to effectively form an embossed collar around the opening 40, thereby ensuring a substantially flat, even flat surface of close tolerances around the opening 40 for critical sealing interaction with the peripheral flange portion 34, as previously disclosed.
  • the opening 40 defined by the score-line 36 need not have the specific shape illustrated in the drawings. A wide variety of other shapes and sizes could be used instead, as required.
  • the prime consideration is that the closure portion 32 of the main body should have an overall size and shape slightly greater than that of the opening 40, the skirt portion 37 should have the same general size and shape as the opening 40 so as to provide for a close fit of the closure portion 32 within the opening 40 in sealing, but non-jamming relation therein, and the grippable ring portion 28 should have a size sufficient to enable it easily to be manipulated to open the can 22 in the first instance.
  • closure portion 32 may be reinforced, for example by the provision of ribs (not shown) , to ensure they has sufficient strength to sheer the movable region of material 38 away from the non-movable part 42 of the top wall 26.
  • the mounting means is positioned on the top wall 26 of the can 22 in the movable region of material 38, such that the movable region of material 38 is removable from said top wall 26.
