Abstract
A core for compressed core wound paper products adapted for rotation on a spindle. The core is deformable from a generally rounded configuration to a generally flattened configuration for transportation and storage. The core includes tab portions that are deformable to extend radially inward of core inner and outer surfaces to reduce core to spindle clearance when the core is rounded for use.
Claims16
A hollow core about which a paper product may be wound, the core adapted to be supported on a spindle for dispensing of the paper product, and the core being deformable from a generally rounded configuration to a generally flattened configuration, the core comprising:
- an inner surface and an outer surface separated by a core wall having a finite thickness;
- first and second longitudinally spaced apart core ends defining a longitudinal core axis and a core length;
- at least one tab portion deformable to extend radially inwardly of the core surfaces when the core is in the generally rounded configuration, each tab portion comprising:
- at least one longitudinally and circumferentially extending panel;
- and
- a selectively weakened panel attachment to the core.

- an inner surface and an outer surface separated by a core wall having a finite thickness;
- first and second longitudinally spaced apart core ends defining a longitudinal core axis and a core length;
- at least one tab portion deformable to extend radially inwardly of the core surfaces when the core is in the generally rounded configuration, each tab portion comprising:
- at least one longitudinally and circumferentially extending panel;
- a first curvilinear selectively weakened panel attachment to the core;
- and
- a second curvilinear selectively weakened panel attachment to the core, at least a portion of the second curvilinear selectively weakened panel attachment spaced circumferentially from the first curvilinear selectively weakened panel attachment.
