Abstract
System for packaging cup-like coffee filters, consisting of nesting the filters so that their upper edges form a frusto-conical surface and of providing a tab associated with each filter, so that the innermost filter can be readily separated from the others.
Claims3
Coffee filter system, comprising:
- (a) a plurality of cup-like disposable filters, each filter having a generally circular bottom wall and a generally frusto-conical side wall, said filters being arranged in a nested stack, and
- (b) a continuous elongated tab element that is threaded sinuously from one side to another of the plurality of filters to form a tab associated with the innermost filter and which is accessible for grasping by the fingers of a user, so that, as the tab is pulled upwardly, the element lifts the filters one at a time from the remaining filters in the stack,
