Abstract
A easy-open beverage container which can be selectably reclosed and reopened, after the container initially is opened. The reclosure structure may be contained on an opening tab, or alternatively may be separate from the tab.
Claims7
A selectably reclosable easy-opening container apparatus comprising:
- a container wall having an outer surface and an inner surface;
- an openable panel member defined in said wall by a selectively separable region of predetermined weakness;
- a raised flange on said wall surrounding said separable region;
- a unitarily constructed opening and reclosure tab member secured to said wall by first and second attachment means;
- said first means located outside said openable panel member to secure the tab member to the wall;
- said second means located in said openable panel member and across said region of weakness from said first attachment means to secure the panel member to the tab member;
- said opening and reclosure tab member having a closure engaging means selectively operable to engage said raised flange, wherein said raised flange on said wall and said flange engaging means on said tab member form a seal over said openable panel member prior to opening and separation of said openable panel member from said container wall;
- said tab member having means confronting said wall in the vicinity of said region of weakness and operative to separate the region of weakness when the tab is first pressed downwardly to separate and displace said openable panel member and is then lifted up a limited distance to pivot said connected tab member and said panel member across said wall;
- and
- said tab and said opened panel member are thereby pivotable across said end wall around said first attachment means while the second attachment means moves with the tab member and the opened panel member, so as to provide a pour opening in the container wall.

A container wall having an outer surface and an inner surface;
- an openable panel member defined in said wall by a first selectively separable region of predetermined weakness;
- a second region of selectively separable predetermined weakness forming a vent means located within said openable panel member;
- a raised flange on said wall surrounding said first and second separable regions;
- a unitarily constructed opening and reclosure tab member having a spike means on the underside of said tab member;
- said tab member secured to said wall by a first and second attachment means;
- said first means located outside said openable panel member to secure said tab member to said wall;
- said second means located in said openable panel member and across said region of weakness from said first attachment means to secure said panel member to said tab member;
- and
- said opening and reclosure tab member having a flange engaging means selectively operable to engage said raised flange,
- wherein said raised flange on said wall and said flange engaging means on said tab member form a seal over said openable panel member prior to opening and separation of said openable panel member and said vent means from said container wall.

A selectably reclosable easy-open container apparatus, comprising:
- a container wall having an outer surface and an inner surface;
- an openable panel member defined in said wall by a selectively separable region of predetermined weakness;
- a raised flange on said wall surrounding said separable region;
- a unitarily constructed opening and reclosure tab member secured to said wall by first and second attachment means;
- said first means located outside said openable panel member to secure the tab member to the wall;
- said second means located in said openable panel member and across said region of weakness from said first attachment means to secure said panel member to said tab member;
- said opening and closure tab member having a closure engaging means selectively operable to engage said raised flange, wherein said raised flange on said wall and said flange engaging means on said tab member form a seal over said openable panel member, and wherein
- said tab closure engaging means and said raised flange engaging means on said end wall member remain sealed as downward pressure is applied to said tab member toward said openable panel member in the vicinity of said selectively severable region of predetermined weakness, causing said region to sever and separate the panel member from said wall.
