Abstract: A waste disposal system has a waste disposal device and cassette having a length of flexible film. The cassette has a lower surface and a guide feature enabling the cassette to rotate within the upper housing of the pail, maintain a substantially stationary position within the upper housing of the pail, or combinations thereof. The waste disposal device has a guide member that engages the guide feature of the cassette. The waste disposal device has a cassette housing and a sealing mechanism. One of the housing and sealing mechanism, and the cassette, rotate with respect to the other, either directly or indirectly.

Abstract: A waste disposal system includes a cassette having a latch feature. The latch feature is received within a cassette interface or secured by a cassette interface. A waste disposal device includes a lid that mitigates disturbance of ambient air surrounding the waste disposal device. A liner clamping system has an associated timing that mitigates against air within the interior space of the waste disposal device from travelling upward through the liner clamping system, past the lid (when the lid is in an open configuration) and outward into the surrounding environment.

Abstract: An interface for a waste disposal device includes a cassette and a waste disposal device. Features of the interface reside on the cassette and on the waste disposal device. The interface permits connection of the cassette into the waste disposal device to assist with proper insertion and/or attachment of the cassette to the waste disposal device. In one embodiment, one or more latch features in the waste disposal device engage with one or more ramp features on the cassette body.

Abstract: A pail facilitating ease of use having a pivotable removal bin. A retention structure pivots about a single axis, the retention structure having two sections that create an overlapping pinch about an upper surface in a first position and a lower surface in a second position. A cutter is located proximal the upper end of the removal bin.

Abstract: A cassette for a waste disposal device is provided having a length of tubular liner film. The cassette has a central passage. The cassette has a forward edge, an aft edge, a first edge and a second edge defining a shape and a widthwise axis and a depthwise axis. The depthwise axis and widthwise axis intersect form two segments of each axis.

Abstract: A cassette for disposing waste is provided having a variable cross-sectional geometry. The cross-sectional geometry varies at least at two locations around the periphery of the cassette such that a first maximum height at a first location is different than a second maximum height at a second different location, and the first maximum width at a first location is different than a second maximum width at a second location.

Abstract: A waste disposal system with a compact footprint. The waste disposal system device accepts a cassette having a length of tubular liner film. The waste disposal device and cassette can have similar cross-sectional geometry. The waste disposal device and/or cassette comprise a first wall, a second wall, and a first included angle defined therebetween between about sixty and about one-hundred twenty degrees.

Abstract: In one embodiment, an oral-care system is provided. The oral-care system includes an electric toothbrush having a motor, a power source in electrical communication with the motor, and a bristle holder operatively connected to the motor. A display is in data communication with the electric toothbrush.

Abstract: An oral hygiene device includes a head, a first bristle field, and a second bristle field. The head includes a first head portion and a second head portion. The first bristle field extends from the first head portion. The second bristle field extends from the second head portion. The first bristle field and second bristle field are controllably movable between a first configuration for providing a first cleaning operation and a second configuration for providing a second cleaning operation.

Abstract: A toothbrush has a handle and a head part, on which bristle filaments and at least one flexible cleaning element are arranged. The at least one flexible cleaning element is arranged on a carrier element which consists of a hard material and is connected to the head part. A process for producing such a toothbrush is also disclosed.

Abstract: Oral care treatments are provided, including multi-component oral care compositions and methods for delivering such compositions to the oral cavity. Oral care devices and systems for implementing such oral care treatments are also provided.

Abstract: Fluid couplings are provided for devices that include a flow path having two or more separable portions. Devices including such couplings are also provided, for example, a device including: first and second separable portions; a conduit, within the first portion, defining a flow path for fluid flow between the first portion and the second portion, the conduit having an open terminal end; a valve, within the first portion, including a deformable member configured to cover the terminal end thereby sealing the first portion when the first and second portions are separated; and a member, extending from the second portion, configured to cause the deformable member to deflect so as to expose the terminal end when the first and second portions are connected.

Abstract: Dual valves are described herein. The dual valves have a plurality of lumens disposed within a unitary body. The dual valves can be used, for example, in personal care products such as toothbrushes and razors to dispense fluids such as dentifrice and shaving aids.
