Dry formula mixing apparatus and method of use

摘要

A dry powder and liquid mixing apparatus provides a dry powder container integratable with a liquid container, and a lid engaging both the dry powder container and the liquid container to enable selectable storage and mixing of powder and liquid, such as mixing dry infant formula with water. Through simple manual twisting of the lid about the liquid container to a closed state, a user is able to selectively prevent mixing of stored dry powder and liquid. Likewise, through simple manual twisting of the lid about the liquid container to an opened state, a user is able to selectively enable mixing of the dry powder with the liquid, by shaking the apparatus while the lid is in an opened state, resulting in a consumable mixed formula.

主权项

1. A dry formula mixing apparatus, comprising:
a liquid container having an outer cylindrical sidewall and a spaced-apart inner cylindrical sidewall interconnected by, and contiguous with, an annular base, the contiguous inner and outer sidewalls and annular base defining a liquid container interior chamber adapted for receiving a volume of liquid, the liquid container outer sidewall having a thickened upper portion commencing at an outwardly extending flange, the flange transitioning upwardly into an externally threaded portion on the thickened upper portion, and the externally threaded portion transitioning upwardly into an uppermost section of the thickened upper portion terminating at an outer cylindrical sidewall upper edge, the uppermost section of the thickened upper portion having a sealing member integrated therewith; a stabilizing feature located within an interior space defined by an interior surface of the liquid container cylindrical inner sidewall; a powder container having a cylindrical sidewall extending upward from, and contiguous with, a powder container base, the contiguous cylindrical sidewall and powder container base defining a powder container interior chamber adapted for receiving a volume of powder, the powder container in snug engagement with the stabilizing feature to aid in maintaining a preferred fixed position and orientation of the powder container within an interior space bounded by said liquid container inner sidewall, an upper length of the powder container having a thickened sidewall portion terminating at a flanged upper end, the flanged upper end supported upon an upper edge of the liquid container cylindrical inner sidewall, and an outer surface of the thickened sidewall portion incorporating a sealing member creating sealing engagement with an opposing surface of the liquid container cylindrical inner sidewall; and a generally cylindrically-shaped lid having a top portion contiguous with a main lid sidewall depending downwardly from a perimeter thereof, the main lid sidewall having an upper sidewall portion transitioning into a wider lower sidewall portion, the lower sidewall portion terminating at a main lid sidewall lower edge and having an internally threaded surface for selective threading engagement with the externally threaded portion of the liquid container, a bottom interior surface of the top portion of the lid having a first inner cylindrical lid wall contiguous with, and depending downwardly from, said bottom interior lid surface, and the bottom interior surface of the top portion of the lid having a second inner cylindrical lid wall contiguous with, and extending downwardly from, said bottom interior lid surface, the first inner cylindrical lid wall inwardly offset from the upper portion of the main lid sidewall by a distance defining a gap therebetween, the gap sized and shaped for receiving said uppermost section of the thickened portion of said liquid container outer sidewall therein for facilitating selective sealing engagement of an interior surface of the upper portion of the main lid sidewall and the sealing member integrated with the uppermost section of the thickened portion of the liquid container outer sidewall, the second inner cylindrical lid wall inwardly offset from the first inner cylindrical lid wall and terminating at a second inner cylindrical wall lower edge, the lower edge incorporating a sealing member for providing selective sealing engagement with an upper surface of the powder container flange when said mixing apparatus is in a completely closed state.
