PURPOSE:To obtain a flow rate adjusting mouth plug with which pouring-out in continuous fixed small quantity is available with the flow rate adjusted, letting laminar flow occur naturally without producing turbulent flow. CONSTITUTION:The mouth plug is a topped barrel body equipped with an inner barrel part 5 and an outer barrel part 9 for mounting to the mouth of a container, a top plate part 1, and a pouring barrel 2 provided in projection to the upper part of the top plate part 1, and a clockwise spiral fin 6 is integrally formed to the inner periphery of the inner barrel part 5. A fitting projection is provided to the lower inner periphery of the outer barrel part 9, and discontinuous rifts 11 and a tab 12 are integrally provided to a position above the fitting projection. An opening, formed of a breakable thin part, is provided to the center of the top plate part 1 with a pull-ring provided in projection, and a mounting barrel, equipped with a threaded part, for mounting a cap thereon is provided to a position outside the pouring barrel 2 of the top plate part 1. |
