Claims
- 1. A resealable container end for attachment to a liquid holding container, said end comprising
- a neck portion having a lower edge including a peripheral wing part for incorporation in a rolled seam with an upper edge of a can body,
- said neck portion having a generally cylindrical central upper part of less diameter than said wing part and including a pouring opening with a surrounding curl, said upper part of said neck portion including a ledge about said surrounding curl,
- a first set of lugs formed outward to a first diameter about said upper part for cooperation with a closure hat member,
- a removable closure hat member covering said pouring opening and including a top panel and a rim shaped to extend downward from said top panel around said upper neck part, said rim terminating in a generally circular lower edge,
- a seal member within said closure hat member extending entirely around said rim, said seal member having an inner diameter less than said surrounding curl whereby said seal member can be compressed against said ledge and said surrounding curl when said closure hat member is in place on said neck portion,
- a second set of lugs formed inward within said rim of said closure hat member to a second diameter less than said first diameter of said first set of lugs to latch under said first set of lugs to retain said seal member in sealed relationship with said surrounding curl of said pouring opening.
- 2. A container end as defined in claim 1, further comprising
- said first set of lugs having inclined cam surfaces facing said lower edge of said neck portion for compressing said seal member against said surrounding curl of said pouring opening.
- 3. A container end as defined in claim 1, further comprising said seal member being an elastomeric ring member contained within said rim of said hat member adjacent the junction of said top panel to said rim.
- 4. A container end as defined in claim 1, further comprising
- an outward curl formed on said lower edge of said rim of said hat member, and
- said second set of lugs extending inward from said outward curl.
- 5. A container end as defined in claim 1, further including
- a seal compound applied to the underside of said wing part of said neck portion to be incorporated in the rolled seam formed with a can body rim and said wing part.
- 6. A resealable container end for attachment to a liquid holding container, said end comprising
- a neck portion having a lower edge including a peripheral wing part adapted for incorporation in a seam with a rim of a can body,
- said neck portion having a generally cylindrical central upper part of less diameter than said wing part and including a pouring opening with a surrounding curl, said upper part of said neck portion including a ledge about said surrounding curl,
- a first set of lugs formed outward to a first diameter about said upper part for cooperation with a closure hat, said first set of lugs being of generally triangular shape including inclined cam surfaces facing downward of said upper neck portion,
- a removable closure hat member covering said pouring opening and including a top panel and a rim shaped to extend downward from said top panel around said upper neck part, said rim terminating in a generally circular lower edge,
- a circular seal member within said rim of said hat member adjacent said top panel, said seal member having an inner diameter greater than said surrounding curl whereby said seal member is compressed against said ledge and said surrounding curl,
- a second set of lugs formed inward within said rim of said hat member to a second diameter less than said first diameter of said first set of lugs to latch under said first set of lugs and to retain said hat member in sealed relationship with said surrounding curl of said pouring opening.
- 7. A container end as defined in claim 6, wherein said seal member is an elastomeric ring-like member contained within said rim of said hat member adjacent the junction of said top panel and said rim.
- 8. A container end as defined in claim 6, further comprising
- said surrounding curl being an outward curl formed on said lower edge of said rim of said hat member, and
- said second set of lugs extending inward from said outward curl.
- 9. A container end as defined in claim 8, further including a ledge formed on said upper neck part, from which ledge the outward curl surrounding said pour opening is formed.
