Abstract: A composition dispenser with dynamically adjustable protrusions/bristles for delivery of a cosmetic composition to a substrate, particularly hair coloring agents. The composition dispenser comprises a protrusion unit including one or more protrusion elements and at least one dispensing orifices appointed for fluidic communication with a formulation reservoir. The protrusion unit is operably coupled to a length-adjustment element configured to adjust an exposed protrusion length of the protrusion elements along a direction perpendicular to a rotation plane of the length-adjust element.

Abstract: A manually actuated drug-injecting device is configured such that the grip strength of the entire hand (i.e., majority of fingers closing toward the palm or heel of the hand) is employed to discharge medication through a hypodermic needle and into a patient's body. The device is well suited for delivering medications with high viscosity and/or by patients (e.g., elderly patients) with reduced finger strength and dexterity. The device includes a grip member, a push member (which causes the medication to be injected), and a force-transfer mechanism that couples the grip member to the push member. Suitably, the device is configured to be held transverse to the palm of the medication-administering hand, with a discharge port located by the outer, blade edge of the administering hand, when the device is being gripped to administer medication.

Abstract: An adjustable applicator head with protrusion elements and a dispensing orifice in fluidic communication with a formulation reservoir operably coupled to a sliding length-adjustment element configured to adjust an exposed protrusion length of the protrusion elements along a direction parallel to a central axis of the length-adjustment element. The applicator can be refilled and re-used and is adjustable for different lengths of hair and hair styles. The tines or bristles can be replaced with foam applicators, sponges, or other surfaces for various applications, such as skincare, makeup or makeup removal.

Abstract: Cosmetic assemblies are movable between a resting state and a compressed state. The cosmetic assemblies include an applicator and an actuator. The applicator is at least partially formed of a compressible material that is biased toward the resting state, and the actuator is configured to actuate the applicator between the resting state and the compressed state. In the resting state, the applicator displaces a first volume and has a first outer dimension. In the compressed state, the applicator displaces a second volume that is less than the first volume, and the applicator has a second outer dimension that corresponds to and exceeds the first outer dimension.

Abstract: Packaging systems include a container having a mouth, a workpiece, and an insert configured to receive the workpiece and to retain the workpiece within the mouth of the container in an axially aligned configuration. The insert has an annular wall with an outer surface that tapers from a first outer diameter proximal a first end thereof to a second outer diameter proximal a second end thereof. The second outer diameter is greater than the first outer diameter, and the first end is configured for insertion into the mouth of the container before the second end.

Abstract: A dual conductive electrical jumper clamp system has two jumper clamps, each jumper clamp having upper and lower clamp frames and an electrical conductive contact plate positioned within each frame. An electrical conductive sleeve is positioned between the contact plates. In this manner, electricity is transmitted from an electric power source to only one of the contact plates, then solely to the other contact plate via the conductive sleeve, and ultimately to electrical terminal attaching jaw members at the ends of the contact plates.
