Definitions

  • a preferred solution to the problems created by the conventional pop-top would be an easy opening container which is manually operable by children as well as adults, which provides an effective pouring opening once opened, which presents no psychological barriers to opening or beverage consumption, which is readily producable, and which is economically feasible. While many designs of easy-opening containers have been proposed as substitutes for the conventional pop-top, none is known which effectively meets all foregoing criteria to the satisfaction of the container manufacturer, the beverage packager, and the consumer of canned beverages.
  • the easy opening top closure member is utilized with a container having a top member with an aperature of a predetermined configuration.
  • the closure member has an exterior portion and an interior portion.
  • the exterior portion is in the form of a retaining ridge that extends upwardly from the interior portion with the retaining ridge functioning to provide a surface against which the tip of a finger can be pushed to uncover and also to cover the aperature.
  • the interior portion is in the form of a disc whose lateral dimensions are greater than that of the aperature whereby the outer periphery of the disc functions as a pressure sealing lip against the underside of the top member.
  • the lower portion of the retaining ridge is frangibly connected to the disc along a predetermined portion of the retaining ridge whereby either a downward force against the predetermined area of the disc or an upward pulling force against a predetermined portion of the ridge will cause the retaining ridge to separate from the disc along the predetermined frangible portion thereby allowing the closure member to be slid rearwardly and forwardly to respectively open and close the closure member.
  • the lower portion of the retaining ridge that is not frangibly connected to the disc is of a thickness greater than the frangible portion and the thicker portion functions as a hinge connecting the retaining ridge to the disc.
  • the closure member is made of a suitable plastic or metal material that can be used with a beverage can that is made of metal or even a blow-moulded one piece plastic can such as recently has been manufactured.
  • the disc member may have a concave portion that extends downwardly below the bottom surface of the pressure sealing lip portion of the disc.
  • the disc has a fingertip pressure surface that extends laterally inwardly a predetermined distance from the retaining ridge. By applying a downward force to the fingertip pressure surface, the lower portion of the retaining ridge that is frangibly connected to the disc will sever along the predetermined frangible portion.
  • the fingertip pressure surface is hinged at its forward edge.to a downwardly extending wall member whose lower edge meets the concave portion of the disc.
  • fingertip pressure is applied rearwardly toward the vertical wall of the retaining ridge which will cause the closure member to move rearwardly thus uncovering the aperature in the top of the beverage can.
  • the closure member By sliding the closure member back into its pre-opened position, the aperature may be covered again thereby keeping the liquid in and foreign particles out.
  • the novel closure member is easy to open because the seal which has to be broken is not the seal which contains the pressure of carbonation. Only the retaining ridge has to be separated from the pressure-holding disc portion of the seal when opening the can.
  • the novel closure member is also more sanitary than previous easy-open tops for beverage cans because, after opening the can, the top surface of the disc lies flat against the underside of the top wall of the beverage can and does not extend into the liquid. Neither is the finger immersed, as happens with the push-in top beverage can.
  • the novel closure member is also much safer than previous easy-open top beverage cans since the retaining ridge only serves to hold the sealing disc in place and to provide a finger hold. Very little strength is needed between the retaining ridge and the disc thus reducing the seal breaking force to the point where little or no recoil occurs in the pull-up mode, or fingers being cut in the push-in mode. During seal breaking, the finger is protected by the retaining ring and the fingertip pressure surface.
  • the retaining ridge has a laterally inwardly extending flange adjacent the area where the retaining ridge is frangibly connected to the disc whereby a predetermined upward lifting force against this laterally inwardly extending flange will sever the retaining ridge from the disc along the frangible portion.
  • the outer lateral surface of the retaining ridge has a convex portion that functions to prevent the closure member from being pushed inwardly through the aperture in the top member of the container.
  • a container made from plastic or metal is generally designated numeral 12 and it has a side wall 14 and a top member 16.
  • An aperature 18 of a predetermined configuration is formed in the top member and into this aperature is fitted the closure member 20.
  • the exterior portion of the closure member 20 is in the form of a retaining ridge 22 that extends upwardly from a disc member 24 whose lateral dimensions are greater than that of the aperature 18 whereby the outer periphery of the disc functions as a pressure sealing lip against the underside of the top member 16.
  • the thickness of the material of the retaining ridge is relatively thin along the neck area 26 connectinq the retaining ridge 22 to the disc member 24.
  • the thinness of the material makes it easily frangible by either a downward force against the fingertip pressure surface 28 or an upward pulling force against the retaining ridge.
  • the thickness of the material along the lower portion of the retaining ridge at its foreward end is thicker and non-frangible to form a hinge 30 that connects the retaining ridge to the disc member after the closure member has been slid to its open position.
  • the retaining ridge 22 is formed in the shape of a ring, and its outer lateral surface has a convex portion 32 that functions to prevent the closure member from being pushed inwardly through the aperature in the top member of the container.
  • the disc may also have a concave portion 34 that extends downward below the bottom surface of the pressure sealing lip portion of the disc 24.
  • the alternative closure member 20 prine is illustrated in Figures 8 and 9. Its like structural elements are identified by the like numbers used for identifying the structure of the first closure member. The main difference between the two is the addition of a laterally inwardly extending flange 40 adjacent to the area where the retaining ridge 22 is frangibly connected to the disc 24. By applying a predetermined upwardly force against the laterally inwardly extending flange 40, the lower portion of the retaining ridge will sever from the disc 24 along the frangible portion between the two structural elements.
