Abstract: The present disclosure provides a composition. In an embodiment, the composition includes a polymer component and an odor suppressant. The polymer component includes (i) a post-consumer resin and (ii) optionally an olefin-based polymer. The composition further includes from 0.15 wt % to 15 wt % of the odor suppressant. The odor suppressant includes (i) from 0.05 wt % to 2 wt % of a metal oxide having a band gap greater than 5.0 electron volts (eV); and (ii) from 0.1 wt % to 13 wt % an acid copolymer. The ratio of metal oxide to acid copolymer is from 1:20 to 1:1. Weight percent is based on total weight of the composition.

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.
