Definitions
- the present invention relates generally to beverage container end closures. More specifically, the present invention relates to beverage container end closures with pull tabs and easy opening features including a deep fmgerwell positioned proximate to the pull tab.
- SOTs Food and beverage containers with pull tabs or stay-on-tabs
- Various SOTs and related features are disclosed in, by way of example, U.S. Patent 7,926,675 to Rieck et al, the entire disclosure of which is hereby incorporated by reference in its entirety.
- Known devices generally position a distal or "tail" end of a pull tab in close proximity to the panel of the end closure to allow stacking of the end closures prior to and after filling of the beverage container.
- Such an arrangement particularly where can contents are placed under pressure, pose various complications and challenges with operating the tab and opening a portion of the panel. Such complications include, but are not limited to difficulty in engaging or grasping the tab and risks of damage or injury to a user's finger(s) or fingernail(s).
- the present invention contemplates a novel system, device, and methods for providing a food and beverage container end closure with easy opening features for a pull tab disposed on the end closure, and more specifically a deep fmgerwell to permit the access of a user's finger below the lift ring of a pull tab.
- End closures of the present disclosure provide, for example, the structural features and benefits, stacking abilities, and ease of manufacture of various known devices, and further provide a deep fmgerwell recess allowing for ease of access to the operative (i.e. bottom) side of tab, thereby increasing user- friendliness of the device.
- an end closure is provided with a SOT and a dimple shaped fmgerwell in the panel.
- the fmgerwell is preferably disposed generally proximal to a distal or user end of the tab.
- the fmgerwell is disposed such that at least a portion of the tab extends over at least a portion of an area defined by the fmgerwell and facilitates user-access to an underside of the tab for lifting.
- an end closure with a fmgerwell is provided, the fmgerwell having a generally rounded shape when viewed from a top plan view.
- a fmgerwell is provided having a depth of between approximately .010" and approximately .060" as measured from the panel.
- a fmgerwell is provided having a depth of between approximately .020" and approximately .050" as measured from the panel.
- a fmgerwell is provided having a depth of between approximately .025" and approximately .040" as measured from the panel.
- an end closure with a deep fmgerwell and improved geometry is provided to allow access to a pull tab and provide for increased normal force to be imparted upon the pull tab.
- the present invention contemplates the provision of a fmgerwell preferably sized to allow for user access to a pull tab and allow for greater normal force to be applied to the pull tab when compared with known devices. It is known, for example, that existing pull tabs are not only difficult to access but further result in a significant amount of the force being applied to the pull tab in a direction or vector parallel with an opening area. Such a force places stress upon a rivet and provides reduced ability to score or open an opening area. Fingerwells of various embodiments of the present invention allow for a user to provide an initial force upon the tab with an increased degree of normal force, further facilitating opening operations.
- the improved end closure allows the stacking of multiple end closures and filled food or beverage containers.
- a metallic container end closure adapted for interconnection to a neck of a metal beverage container.
- the end closure comprises: a peripheral curl adapted for interconnection to the neck of the container; a chuck wall interconnected to the peripheral curl and extending downwardly therefrom; a countersink interconnected to a lower end of the chuck wall; an inner panel wall interconnected to the countersink; a central panel interconnected to an upper end of the inner panel wall; the central panel comprising a debossed area with a substantially tear drop shape, the debossed area disposed at a lower height than the central panel and wherein the debossed area comprises a rivet for securing a pull tab with a forward end and a tail end, the forward end positioned over selective opening area defined by a score line; and the debossed area comprising a fmgerwell portion extending below a substantially horizontal plane defined by the debossed area, wherein the fmgerwell comprises a substantially planar lower portion and opposing side walls,
