摘要： 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.

摘要： The present disclosure is directed to a dosing cap (10). In an embodiment, the dosing cap (10) includes (A) a collar member (12). The collar member (12) has an annular skirt (18) depending from a base (16)(B). An inner surface of the skirt has a securing member for securing the collar member to a neck (21) of a container (20). The base (B) has (i) a top surface (30) and a bottom surface (32), (ii) a valve seat (34) is present on the top surface of the base. The valve seat has a center channel (36), and a radial channel (38), the channels extend through the base. The dosing cap includes (C) a plug member (40). The plug member is composed of a polymeric material. The plug member has the following components in inter-connected relationship: a head (42), a body (44), a leg (46), an ankle (48), and a flexible foot (50). The leg extends through the center channel, such that the head opposes the valve seat on the top surface of the base and the foot opposes the bottom surface of the base. The dosing cap further includes (D) a cap member (112) having an annular sidewall (118) extending from a dispensing element (114). An inner surface of the annular sidewall has an attachment member adjustably attached to a reciprocal attachment member on an outer surface of skirt. The dosing cap includes (E) a metering chamber (120). The metering chamber is formed by an enclosed volume between the cap member and the base. The dispensing element (F) permits flow of a fluid from the metering chamber.
