ABSTRACT:
A longitudinally slotted sleeve constructed of stiff, but slightly resilient material is provided with one end of the longitudinal slot being outwardly flared. The one end of the sleeve may be longitudinally advanced into engagement with a flattened reversely folded flattened portion of a collapsible tube in order to prevent fluent material within the non-flattened end of the tube from returning to the flattened end portion thereof when the non-flattened end is squeezed to express additional fluent material therefrom.
