Abstract
A mixing device and method wherein liquids are rotatingly mixed in a disposable plastic bag mounted in and outer receptacle. The bag is provided with extending portions which overlap the open top of the outer receptacle. The interior sidewalls of the outer receptacle are inwardly sloping defining a truncated conical interior. When the bag is filled with liquid to be mixed the bag conforms to the sidewalls and does not twist around a rotating mixing element disposed through the open tops of the bag and outer receptable for mixing the contents of the bag. The mixing element is centered in the bag by a cap-like cylindrical structure that engages the top of the outer receptacle.
Claims19
An apparatus for mixing and agitating a liquid, the apparatus comprising:
- a rigid outer receptacle defining an interior and having an open top, the receptacle is provided with interior sidewalls that have an inwardly sloping configuration;
- and
- a flexible and disposable liquid resistant bag having an open top, a closed bottom and sidewalls, the bag is adapted and constructed to line the interior sidewalls of the outer receptacle;
- when liquid to be mixed is deposited into the bag, the bag expands contacting the sidewalls of the outer receptacle, a mixing element can then be placed through the open tops of the receptacle and the bag for mixing liquid contained in the bag.
A method of mixing at least two components wherein at least one is a liquid, comprising the following steps;
- placing a disposable liquid resistant bag having an open top into an outer receptacle having an open top so that the bag nests in the outer receptacle, the outer receptacle has interior sidewalls that are inwardly sloping and adapted to contact the sidewalls of the disposable bag;
- depositing the two components into the liquid resistant bag which is nested in the outer receptacle so that the sidewalls of the bag expand into contact with the inwardly sloping sidewalls of the outer receptacle;
- placing a rotary mixing element of a rotary mixing means into the components located in the bag;
- and
- rotating the rotary mixing element mixing the components located in the bag.
