Abstract: An agitator may include one or more members adjustable between an expanded configuration and a compressed configuration. When the one or more members are in the expanded configuration, the agitator in a first set of two orthogonal dimensions is larger than an opening having a predetermined size. When the one or more members are in the compressed configuration, the agitator in a second set of two orthogonal dimensions is smaller than the opening having the predetermined size. The one or more members are biased to the expanded configuration in absence of external force applied to the one or more members. In use, the agitator may be inserted into a container through a neck of the container in the compressed configuration. The agitator may expand within the container so that the container does not fit through the neck of the container.

Abstract: A folio for use with a tablet computer comprises a pair of leafs pivotally coupled together at a hinge with a keyboard carried by one of the pair of leafs, and another of the pair of leafs carrying the tablet computer and defining a cover for the keyboard in the closed configuration. A fixed top stop is fixed to the cover opposite the hinge and extends outwardly from the cover configured to abut to the tablet computer. A sliding shelf is movably coupled to the cover adjacent the hinge and opposite the fixed top stop to receive the tablet computer thereon in the open configuration. Bias means is coupled to the sliding shelf for biasing the sliding shelf towards the fixed top stop.
