  • Publication number: 20130239821
    Abstract: A cylindrical travel mug or container with or without a handle and drinking top/lid, lower tea compartment housing with one or more mesh screens, and removable bottom. The removable bottom is comprised of a threaded base bap, rubber seal, conical tea compartment for retaining a tea bag and an on/off control knob. The tea compartment is connected to the base with a press release that allows it to swing open against an opposing hinge from the release so a tea bag can be inserted or removed. The conical tea compartment is further comprised of one or more mesh openings through which liquid and tea may be transferred. An on/off control switch is used to rotate the tea compartment and its mesh screens with respect to the tea compartment housing and its mesh screens to enable control of the starting and stopping of tea infusion or steeping.

  • Patent number: 4047640
    Abstract: The regulator assembly comprises body member carried by a support and defining a cavity for detaining a pool of abrasive slurry. An overflow device is associated with the body member for establishing the upper level of a pool of abrasive slurry in the cavity. At least one flow-restrictive conduit component is secured at one end to the body member, communicates with the cavity at the lower end of the pool of abrasive slurry, and presents an outer end from which abrasive slurry is discharged. One of the above-indicated elements is movable whereby to selectively adjust the vertical distance between the plane of the upper level of the pool of abrasive slurry and the plane of the outer end of the conduit component.
