Abstract: A roll-on applicator including a fluid container surmounted by a fitment of a plastic composition and retaining an applicator ball. A closure cap, detachably secured, constitutes a cover for the fitment. With the cap removed and the applicator assembly in a functional, liquid-dispensing attitude, the applicator ball is biased upwardly by a pair of coplanar, horizontally extending, parallel spring bars integrally formed with and spanning the ball-holding fixture, the bars bridging the fixture and supporting the ball to establish an annular fluid flow communicating passage between the applicator surface of the ball and the interior of the dispensing container.

Abstract: A roll-on type applicator assembly including a ball-type plastic fitment secured to the collar of a liquid dispensing container, and a closure therefor. The fitment includes an integrally formed sealing ring which constitutes a sharp rim formed at the intersection of a pair of angled annular faces. The applicator ball is supported in the fitment by means of an annular array of spring plates which bias the applicator ball upwardly of and out of contact with the sealing ring when the cap is removed from the container.

Abstract: A container and closure cap therefor which forms a package unit, with the container having an open top, a continuous sinuous surface adjacent the open top, the sinuous surface including rounded projections merging into adjacent rounded recesses, a closure cap for the container, the cap having a skirt and an open bottom with a continuous sinuous surface on the skirt, the last mentioned sinuous surface shaped complementary to the container sinuous surface so that the sinuous surface of the closure cap is adapted to engage the container sinuous surface with the projection of one positioned in the recesses of the other when the closure cap is in closing position, one or the other of said closure cap and container having an annular wall portion offset inwardly of its respective sinuous surface and adapted to interfit within the other of the closure cap or container adjacent its sinuous surface to frictionally secure the closure cap to the container.
