Abstract
Abstract A simplified container-dispenser for material in stick form which includes a cap, a tubular body, and a feed screw assembly. The feed screw assembly comprises a knob and a screw, the screw being integrally molded with the knob and projecting into the stick. Upon rotation of the knob of the feed screw assembly, the screw rotates to push the stick upwardly and out of the tubular body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
In an appliance adapted to contain a projectable stick, the combination comprising: a. a tubular body initially open at both ends thereof; b. a cap for sealing one end of said body; and c. a combination end closure- feed screw assembly rotatably mounted in the other end of said body, i. said assembly including a rotatable knob projecting from said other end of said body and an axially aligned feed screw attached to the top of said knob and extending substantially the full length of said body, ii. said feed screw including an elongated shank having two separate sets of axially spaced apart, large diameter threads integrally formed on and projecting transversely from said shank, iii. said feed screw being axially received in said stick and adapted to project said stick out of said body upon rotation of said knob.
Claim 2
Dependent Claim
