PROBLEM TO BE SOLVED: To provide a built-up funnel which can be planarly folded in no use and assembled upright in use, can be stably stand upright when being stand upright at the mouth of a storage container, secure a wide area of a small-diameter opening part and that of a large-diameter opening part, and is multifunctional.SOLUTION: A built-up funnel 1 consists of a funnel body 2, a leg 3, and an engaging part 4. The funnel body 2 is formed by annularly tying at least four or more even-numbered panel members of plan-view trapezoidal shape so that an open angle as viewed from a side face may be an obtuse angle when assembled to be cubic. The leg 3 is formed of a plurality of columnar members, extended in the axial direction from the lower part of the funnel body 2, and mounted alternately on every other panel members forming the funnel body 2. The engaging part 4 projects outward from the outer peripheral surface of the funnel body 2. |
