Filling device for fluid or pourable material - is of foldable material such as cardboard or plastics sheeting folded to form prismatic filling funnel

摘要

The filling device folds flatly when not in use and is easily foldable outwards to form a funnel. The funnel (2) has four fold edges (C-D,B-=H, A-E,B'-H') running in the direction of the longitudinal axis (6) which in the folded-out state form a body with a rhomboid cross-section. The device comprises two joined funnels (2,4), whereby the lower cross-sectional surface (8) of the upper funnel (2) coincides with the upper cross-sectional surface of the lower funnel (4). The longitudinal axis (6) of the upper funnel (2) forms an angle with the longitudinal axis of the lower funnel (4) and this angle is variable. The sides of the common cross-sectional surface (8) are formed by fold edges (D-H,H-E,E-H',H'-D). USE/ADVANTAGE - A foldable funnel which can be folded flatly for storage and transport.
