  • Patent number: 6568090
    Abstract: A cosmetic pencil and sharpener comprises a cap and pencil portion having a sharpened head on a first end portion of the pencil, an elongated body and a second end portion. The cap includes a recess at one end to engage and cover the pencil head, an intermediate portion and a second closed end portion. The intermediate portion includes a raised angular section located adjacent a longitudinal slot in the cap wall. A blade is mounted to the angular section and extends downwardly into the slot. Rotation of the pencil sharpens the head against the blade while shavings drop outwardly from the slot due to a self-cleaning chisel point protrusion on the cap.

  • Patent number: 5494200
    Abstract: A container for siftable products such as powders, solid particulates, spices, condiments and the like, comprises a bottle having a threaded neck, a screw cap for the bottle, and a sifter member disposed in the cap. The cap and sifter member are yieldably held together to constitute an assemblage which is applied to the bottle after the latter has been filled. The applying of the cap to the bottle forces the sifter to be transferred to and firmly secured on the bottle neck by cooperable configurations thereon, which provide a more aggressive grip or securement than the hold of the cap on the sifter. In consequence, whenever thereafter the cap is removed from the bottle, the sifter will remain operatively secured to the bottle to carry out its function.

  • Patent number: 5094572
    Abstract: A flat drill for boring holes through hard metals and high heat resistance materials such as hard metal and fiberglass. The flute or fluid portion forms a spade with slightly cylindrically concave faces which tend to distally converge. The cutting edges at the base of the drill have a negative rake angle, but a relatively high clearance for this type of drill. The lateral leading edges have a positive rake angle, but are strengthened by cylindrically convex flanks. Nose splits form a small but relatively keen small central burrowing edge which stabilizes the drill.
