Abstract: A single use fluid delivery system including a fluid containing vial fitted with a non-removable sealing plug; a separate fluid applicator non-removably installable on the fluid vial; and a ball seal structure located on the fluid vial and configured to seal the fluid vial until the applicator is installed. The fluid filled and sealed vial and the applicator are provided as separate pieces, and during use of the single dose fluid delivery system the applicator is installed onto the vial, and during installation of the applicator onto the vial, the seal is dislodged and opens a channel for the fluid to flow to the applicator.

Abstract: A suction handle, a suction handle assembly, and an oral care system. The suction handle can include a first axis oriented along a longitudinal direction, a first conduit having a first bore oriented along the first axis, and a second conduit adapted to be coupled to the first conduit, which can have a second bore oriented along the first axis. The first conduit and the second conduit can be movable with respect to one another in the longitudinal direction between a first position in which there is no fluid communication between the first and second bores, and a second position in which there is fluid communication. An actuator can be coupled to at least one of the first conduit and the second conduit that which can pivot about a second axis oriented substantially perpendicularly with respect to the first axis between a first and second actuator position.

Abstract: A liquid dispensing system having a reservoir, a flow through applicator having a bore in flow communication with the reservoir, an applicator mount for mounting the applicator on the reservoir, a removable seal for sealing liquid from escaping the dosing system. A flow restrictor may be incorporated located within a portion of the bore of the applicator to control the flow rate and hence the dosing or application rate of the liquid from the reservoir. Alternatively, or in conjunction with the flow restrictor, a plunger is included within the reservoir to be moved forward when the user squeezes the reservoir to urge liquid in the reservoir from the reservoir.

Abstract: A mechanism for extending and retracting a cosmetic pomade that has a base with a raised portion and a shelf, at least one aperture positioned near the shelf, and a middle portion having a plurality of slots. The mechanism also includes a cup for holding the cosmetic pomade. The cup is positioned within, and has protrusions for engaging the slots of, the base. A spiral guide member is positioned coaxially with the base. The spiral guide member has a helically-shaped track and a substantially smooth portion or extension. An insert is positioned within the base. The insert has at least one radially projecting tab that extends through the at least one aperture positioned near the shelf of the base to contact the substantially smooth extension of the spiral guide member. Preferably, the insert includes two or more tabs and each one of them is made from a flexible material having a relatively low coefficient of friction relative to the material of the spiral guide member.

Abstract: A battery charge indicator is permanently incorporated into a battery to indicate the state of charge. In one embodiment, the indicator includes a compressible chamber which is filled with a viscous gel and which is exposed to the expandable cathode of the battery. As the battery discharges, the cathode expands thus causing the gel within the chamber to be extruded out through an outlet into a viewing channel in an overlying disk. The amount of gel flowing into the viewing channel is proportional to the amount of expansion of the cathode and, thus, indicates the amount of discharge and, conversely, the remaining life of the battery. In a second embodiment, a piston assembly is caused to move with a deformable end wall of the battery and indicia on the side wall of the piston assembly is viewed through a lens as a measure of the remaining amount of expect expansion of the cathode.
