ABSTRACT:
An improved disposable emesis container comprising a bag with its upper end enclosing the wide bottom of a funnel formed of paperboard-like material. The containers are mass-produced in a flattened collapsed condition. In use the funnel is squeezed open and after use generally elliptical complementary panels formed on the upper end of the funnel are folded over on each other to provide a self-retaining closure. The lower end of the funnel has downwardly arcuate score lines in the opposite sides which upon being pressed together following formation of the self-retaining closure, act in cooperation with the closure to close together the opposing bottom edges of the wide bottom of the funnel thereby providing a closed valve within the upper end of the bag so as to retain contents of the bag therein.
