  • Combined barrier and mixer assembly for a cylindrical container
    Patent number: 5829875
    Abstract: The present invention provides an apparatus for first separating and later mixing a of materials stored in a cylindrical container. The apparatus of the present invention serves as an effective barrier during storage of the materials. It also serves as an apparatus for thoroughly mixing the materials when they are ready to be used.The apparatus of the present invention consists of: a mixing member formed with one or more mixing spokes for stirring the materials; a sealing member that releasably attaches to the mixing member and together with the mixing member forms a barrier when the two are joined, but separated from the mixing member allows for the combining of the materials within the container; and a mixing rod that attaches to the mixing member and is long enough to protrude from the container to allow the user to manipulate the mixing member. The apparatus of the present invention is formed so it is difficult for the mixing member and the sealing to reattach once they have separated.
