A swivel-up type dispensing package is disclosed. The package includes a product chamber with an elevator therein to move the product axially. A feed screw and nut are associated with the elevator and relative rotary motion between the feed screw and nut serve to move the elevator axially. The package also includes a button adapted to be depressed by the user in a direction which is generally transverse to the axis of body of the dispensing package. The transverse movement of the button is converted to rotary input to either the feed screw or nut to cause one to rotate relative the other and thereby move the elevator. In the described embodiment the button has an integral pawl which during the transverse movement engages ratchet teeth affixed to a wheel mounted perpendicularly to the axis of the body, causing the wheel to rotate through an arc subtended by driven teeth. The wheel rotates relative to a non-rotatable feed screw threaded through the bore of the wheel, causing the feed screw to advance in an axial direction. Affixed to the top of the feed screw is an elevator which is congruent to a chamber holding the product. By axially moving the elevator into the charge of product, it is moved to the applicating position of the dispensing package. The dispensing package is well suited to contain and dispense cream or solid stick deodorants and antiperspirants.

A swivel-up dispensing package comprising: (a) a container body having an interior product chamber of generally uniform cross section with a lengthwise-extending central axis; (b) an elevator having a cross section congruent to and mounted for axial movement within said chamber, said elevator being nonrotatable relative to the container body; (c) a feed screw aligned with the axis of the chamber, said feed screw having exterior threads, and a nut aligned with said feed screw and having internal threads adapted to engage with the exterior threads of the feed screw, one of said feed screw and said nut being non-rotatable relative the container body and the other being rotatable, the arrangement being such that relative rotary movement between the two causes the elevator to move axially; (d) an outwardly biased button mounted in said container body and adapted to be manually depressed in a radial direction generally transverse the axis of said chamber and to return to the outwardly biased position; (e) an axially rotatable wheel associated with the said other end of said feed screw and nut, said wheel having a plurality of ratchet teeth disposed about its periphery; (f) a resilient support member cantilevered from said button and having an integral pawl at the distal end of said member, said pawl being adapted to engage one of said ratchet teeth and cause rotation of said wheel as the button is depressed, said member being adapted to bend radially outwardly to permit the pawl to slide over said ratchet teeth as the button returns to the outwardly biased position; and (g) a means to bias the said other away from said elevator.
