Abstract: The sharpening apparatus of the present invention preferably comprises a hand sharpener that may be assembled or mounted on the knife (e.g., sold mounted on the knife by the knife manufacturer or purchased separately and mounted on the knife by the end-user), and which may remain on the knife after sharpening.

Abstract: A spring biasing element for causing a temperature responsive shifting element mounted on a plunger to shift at a selected temperature, or at a selected time interval, so as to intermittently spray fluid from a dispenser attachable to a container containing a fluid, the dispenser being ringlessly attachable to the container adjacent the cover of the container valve and includes an actuator operative the fluid to be released from the container into the dispenser, and an intermittent dispensing assembly that provides an intermittent fluid output, the intermittent dispensing assembly including a temperature responsive shifting element, the temperature responsive shifting element being shiftable in response to temperature changes in the dispenser and being generally freely supported around a perimeter thereof in the dispenser.

Abstract: A dispenser for attachment to a container containing a fluid material, including an actuator which keeps the container in a substantially constantly open configuration so as to allow the fluid to pass into the dispenser, and a controllable outlet, through which a portion of the fluid is emitted from the dispenser, substantially independent of the fluid pressure in the container.

Abstract: A dispenser (20) for attachment to a container (22) containing a fluid material, including an actuator (110) which keeps the container (22) in a substantially constantly open configuration so as to allow the fluid to pass into the dispenser (20), and a controllable outlet (36), through which a portion of the fluid is emitted from the dispenser (20), substantially independent of the fluid pressure in the container (22).
