Mixing device
A new mixing device for mixing solids and medium to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has an agitator with a center portion and distal portions of larger diameter than the center portion. The agitator is insertable within a hand-held, shakeable container. The agitator is composed of a framework arranged to provide voids to allow for flow of liquids, powders, and other materials into and out of portions of the agitator. The mixing device also has a weighted member attached adjacent to or within the center of the agitator that increases the momentum of the mixing device when in operation. The weighted member may have a metal core and polymer exterior.
1. A mixing device comprising:
an agitator insertable within a hand-held, shakeable container and composed of a framework comprising a single compression spring arranged to provide voids between coils thereof to allow for flow of one or more of liquids, powders, and other materials into and out of portions of the agitator, the agitator having a center portion, a first distal portion, and a second distal portion, the first and second distal portions having diameters generally larger than a diameter of the center portion; and
an elongated weighted member removably and threadedly affixed to the center portion of the compression spring of the framework and having one or more retention members configured to thread to and retain the weighted member within the agitator.
2. The mixing device of claim 1 , the weighted member further formed as a substantially solid piece without external voids.
3. The mixing device of claim 1 , the one or more retention members oriented generally at an angle to a longitudinal axis of the weighted member and extending outward from a center portion thereof.
4. The mixing device of claim 1 , the weighted member comprised of a metal core with a polymer exterior.
5. The mixing device of claim 1 , wherein the first and second distal portions of the agitator extend beyond the weighted member ends and are configured to generally prevent the weighted member from striking a shakeable container interior when the mixing device is in operation.
6. The mixing device of claim 5 , the first and second distal portions comprising compressible spring ends.
7. A mixing device comprising:
a container for holding liquids, the container configured to be hand-held and shakeable;
an agitator insertable within the container and composed of a framework arranged to provide voids to allow for flow of one or more of liquids, powders, and other materials into and out of portions of the agitator, the agitator having a center portion, a first distal portion, and a second distal portion, the first and second distal portions having diameters generally larger than a diameter of the center portion; and
an elongated weighted member removably and threadedly affixed to the center portion of the agitator, the weighted member comprising only a single piece without external voids and having one or more retention members oriented generally perpendicular to a longitudinal axis of the weighted member and configured to thread to and retain the weighted member within the agitator;
the framework further comprising a single compression spring with compressible spring ends that extend beyond weighted member ends, the compressible spring ends configured to generally prevent the weighted member from striking the shakeable container interior when the mixing device is in operation.
8. The mixing device of claim 3 , wherein the one or more retention members comprise a first set of retention members with a thickness exceeding a space between adjacent coils of the compression spring of the agitator, thereby threading of the weighted member into the coils of the single compression spring causes longitudinal expansion of the compression spring coils located in contact with the first set of retention members to facilitate the affixed connection between the weighted member and the framework of the agitator.
9. The mixing device of claim 8 , wherein the first set of retention members comprises a first retention member extending on one side of the weighted member and a second retention member extending on another side of the weighted member opposite the first retention member, wherein the second retention member extends further away from the weighted member than the first retention member.
10. The mixing device of claim 7 , wherein the weighted member comprises a coated metal core.
11. The mixing device of claim 10 , wherein the weighted member comprises a metal core with a polymer exterior.
12. A mixing device comprising:
an agitator insertable within a hand-held, shakeable container and composed of a framework comprising a single compression spring arranged to provide voids between coils thereof to allow for flow of one or more of liquids, powders, and other materials into and out of portions of the agitator, the agitator having a center portion, a first distal portion, and a second distal portion, the first and second distal portions having diameters generally larger than a diameter of the center portion; and
an elongated weighted member removably and threadedly affixed to the center portion of the compression spring of the framework and having one or more retention members configured to thread to and retain the weighted member within the agitator,
wherein once threaded into the single compression spring of the agitator, the weighted member is retained within thereof by the one or more retention members forming an interference fit between adjacent coils of the single compression spring.
13. The mixing device of claim 12 , the one or more retention members oriented generally at an angle to a longitudinal axis of the weighted member and extending outward from a center portion thereof, the one or more retention members are configured to bias adjacent coils of the single compression spring for enhanced retention of the weighted member therein.
14. The mixing device of claim 12 , the weighted member is a single piece comprised of a metal core with a polymer exterior.
