Abstract
The present invention is an end closure structure for a container having a flexible central member (6) with an outwardly dished center section and at least one opening structure (18) in the central member (6), a removable thin flexible closure member (12) disposed over the opening structure (18) which is in a first sealing relationship (32) with a portion of the opening structure (18) and a second sealing relationship (34) with the top surface of the central member (6), an upwardly extending flange member (8) circumferentially disposed from the peripheral edge of the central member (6), and a downwardly extending sealing skirt (10) circumferentially disposed from a top edge of the flange member (8).
Claims19
An end closure structure for a container comprising:
- a flexible central member having an outwardly dished center section and at least one opening structure disposed in said central member;
- a removable flexible closure member disposed over said opening structure and said closure member is in a first sealing relationship with a portion of said opening structure and a second sealing relationship with a top surface of said central member;
- and
- means disposed from a peripheral edge of said central member for sealing said end closure structure to an open end of said container.
A container structure comprising:
- a tubular member having open top and bottom ends;
- a top end closure structure sealed at said top end of said tubular member having a flexible central member with an outwardly dished center section and at least one opening structure disposed in said central member, a removable flexible closure member disposed over said opening structure which is in a first sealing relationship with a portion of said opening structure and a second sealing relationship with a top surface of said central member, and means disposed from a peripheral edge of said central member for sealing said top end closure structure to the top open end of said tubular member;
- and
- a bottom end closure structure sealed at said bottom end of said tubular member having a flexible central member with an outwardly dished center section, and means disposed from a peripheral edge of said central member of said bottom end closure structure adapted to be in a sealing relationship with said tubular member at said open bottom end.
A container structure comprising:
- a tubular member having open top and bottom ends;
- a top end closure structure sealed at said open top end of said tubular member having a substantially planar central member and at least one opening structure disposed in said central member, a removable flexible closure member disposed over said opening structure which is in a first sealing relationship with a portion of said opening structure and a second sealing relationship with a top surface of said central member, and means disposed from a peripheral edge of central member for sealing said top end closure structure to said top end of said tubular member;
- a bottom flexible end closure structure sealed at said bottom end of said tubular member having a flexible central member with an outwardly dished center section, and means disposed from a peripheral edge of said central member of said bottom end closure structure adapted to be in a sealing relationship with said tubular member at said open bottom end.
An end closure structure for a container comprising:
- a substantially planar central member having at least one opening structure disposed in said central member;
- a removable flexible closure member disposed over said opening structure and said closure member is in a first sealing relationship with a portion of said opening structure and a second sealing relationship with a top surface of said central member;
- and
- means disposed from a peripheral edge of said central member for sealing said end closure structure to an open end of said container.
