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.
Claims2
In a disposable emesis container consisting of a bag and a wide bottom funnel with the mouth of the bag fitting over and secured to the bottom of the funnel, said bag and funnel having a normally flattened collapsed empty condition, said funnel being formed of a material having paperboard-like stiffness and flexibility with the convex upper edges thereof juxtaposed in the flattened condition of the funnel, said funnel having juxtaposed concave score lines formed in the opposite sides thereof in the flattened condition with the opposite ends thereof terminating at the opposite ends of said convex upper edges, and said convex upper edges and their associated concave score lines forming generally elliptical panels with pointed ends at the mouth of said funnel which upon being inwardly folded-over one another provide a self-retaining closure for said container, the improvement which comprises:
- downwardly arcuate score lines in the opposite sides of said funnel adjacent said wide bottom thereof which are juxtaposed in registration in the flattened collapsed condition of the funnel and which upon being pressed together when said funnel is open but after said generally elliptical panels have been folded-over on each other, act to close together the bottom edges of said wide bottom.
