Abstract: A toothbrush includes: a handle shaped and dimensioned to be grasped by a human hand; necks coupled to the handle; bristle supports coupled to the necks; and bristles coupled to the bristle supports. The toothbrush, through the bristles coupled to the bristle supports and the necks, is configured to adapt to a dento-gingival junction and all other changing surfaces encountered during brushing to disrupt plaque. The necks provide (i) resistance above 0.35 kilograms of brushing pressure force and (ii) resiliency below 3.77 kilograms of brushing pressure force. The bristles, the necks, and the bristle supports, in combination, provide (i) resistance above 0.55 kilograms of brushing pressure force and (ii) resiliency below 3.89 kilograms of brushing pressure force.

Abstract: A new and improved toothbrush has a pair of discreet twin brushing heads. The heads are arranged side-by-side with independent head flexure. The heads are attached to the handle through use of two discrete neck segments that have purposeful flexure. Each head is connected to one neck segment, thereby permitting independent head flexure. The heads may be angled relative to each other so as to provide two discrete stabilizing contact areas, these contact areas being the respective "high" areas of the two brushing heads that initially meet the teeth and gum surfaces.

Abstract: A new and improved toothbrush has a pair of discreet twin brushing heads. Each head is attached to the handle portion at a predetermined angle relative to the handle portion. The heads are arranged in a side-by-side manner with the angle of the heads tilted in the opposite directions relative to the handle portion. In one embodiment, the heads are fixed relative to the handle portion. In another embodiment, the heads are fixed relative to a handle portion, but the handle portion flexes when sufficient pressure is applied to the brushing heads during brushing. In still another embodiment, each head pivots independently of the other head about a base head which is attached to the handle portion. One unique aspect about the twin-headed toothbrush is that the toothbrush is specifically designed to be used with the conventional brushing technique that the majority of the people are accustomed to, but provide an effective cleaning of teeth and gum surfaces.

Abstract: An improved method of brewing coffee and a device therefor are disclosed. The method involves the steps of providing a coffee brewing device having a porous housing containing a supply of ground coffee and having a self-supporting handle dimensioned to be hand-held attached thereto for positioning and stirring the housing in a liquid, the housing also including a vent for venting gases from an interior portion of the housing, the gases being generated during brewing, at least partially submerging the housing in the liquid and stirring the housing in the liquid using the handle to produce a flow of liquid in the housing, and controlling the flow of liquid produced within the housing to create turbulence therein to agitate the ground coffee while the generated gases are being vented from the housing by the vent for rapid brewing of the coffee.

Abstract: A coffee brewing device includes a housing for holding ground coffee with at least one wall of the housing being formed from a permeable filtering membrane which permits a flow-through of water. The interior of the housing is vented to the atmosphere through an attached conduit, which can be used as a handle, so as to permit the escape of gases which are generated when the coffee grounds are submerged in a cup of hot water. Baffles which serve to control the extent and direction of gas movement may be positioned in the housing. By such control, the generated gases may be utilized to agitate the coffee grounds to thus get a more complete mixing of the grounds with the water prior to a venting of the gases to the atmosphere. The baffles may be of both a perforated and non-perforated design so as to control gas bubble size and direction of flow.
