Abstract: The present disclosure provides a dosing cap. In an embodiment, the dosing cap includes (A) a collar member having an annular skirt depending from a base. An inner surface of the annular skirt has a securing member for securing the collar member to a neck of a container. The base includes (i) at least one opening with a one-way valve permitting fluid flow in a first direction, and (ii) an air channel with a one-way valve permitting fluid flow in a second direction. The dosing cap includes (B) a cap member having an annular sidewall extending from a dispensing element. An inner surface of the annular sidewall has an attachment member adjustably attached to a reciprocal attachment member on an outer surface of the first sidewall. The dosing cap includes (C) a metering chamber formed by an enclosed volume between the cap member and the base. The dosing cap includes (D) the dispensing element permitting flow of a fluid from the metering chamber.

Abstract: A dynamic mixer (40) comprising a rotatable structure (10, 111, 11, 1, 2, 3, 4, 5) having a cylindrical base (14) having a connector disposed at one end, an opposing thinned end, flights of 3 to 6 blades (11, 12, 151, 61), separated by a notches (13, 18) the blades (11, 12, 151, 61) have an inlet face facing the connector end, an outlet (30) face facing the thinned end, a leading edge (21) facing the direction of rotation, a trailing edge (20) opposite the leading edge (21), a standard leading face (154, 65) which tapers from the leading edge (21) to the outlet (30) face and a standard trailing face (166) which tapers from the trailing edge (20) to the inlet face, or a reverse leading face (154, 65) which tapers from the leading edge (21) to the inlet face and a reverse trailing face (155, 66) which tapers from the trailing edge (20) to the outlet (30) face, the notches (13, 18) are offset from one another and the article is adapted for use in a dynamic mixer (40) to mix viscous material when rotated in the mixer (40). An article comprising the mixer (40), a shell (25, 28, 29, 31) about the mixer (40) and an endplate (33) that defines material inlets and seals the inlet end (15, 27) of the mixer (40).
