Abstract

A disposable liquid applicator includes a plastic tube with a tapered neck portion. A brush holder is disposed in the neck portion and includes bristles extending outwardly therefrom. A cap is integrally formed with the neck of the tube and encloses the bristles. The neck includes an annular reduced thickness portion surrounding the brush holder adjacent the cap which is removed by breaking the cap at the reduced thickness portion. The brush holder covers the reduced thickness portion and prevents leakage therefrom during storage.
