US 10,492,586 B2 · Material dispenser/applicator

Abstract

An applicator for a semi-solid material (e.g. lip balm) with an elastomeric material base cap has an interior tube long enough to cooperate with other structures to allow ejection of the plunger associated with the lip balm and its shaft by continued depression of the base cap. This allows easy replacement of the lip balm in the applicator when the original is used up. The applicator also has a tubular housing with interior guide hub with ribs configured and positioned to preclude spinning of the shaft of the plunger mounting the lip balm. A dispenser for flowable material (such as lotion) comprises a bellows mounted in a housing with an elastomeric material base cap at one end, and an end cap at the other end with a first part connected to the housing by screw threads, and a second part connected to the first part by a living hinge.

Dependent claims

An applicator for a semi-solid material comprising:

a generally tubular housing having first and second ends;
a plunger to which semi-solid material is mounted extending exteriorly of said housing first end, said plunger including a shaft with a first surface manifestation;
an elastomeric material base cap mounted to said second end of said housing and having an interior structure comprising a second surface manifestation releasably engaging said first surface manifestation so that by continued depression of said base cap said elastomeric base cap is movable to a position which disengages said first and second surface manifestations which then allows ejection of the plunger and its shaft from said housing.

A dispenser for dispensable material comprising:

a generally tubular housing having first and second ends;
a dispensable material containing or supporting structure including a shaft having a first surface manifestation thereon;
an elastomeric material base cap at said second end of said housing and having a generally central structure with a second surface manifestation releasably operatively cooperating with said first surface manifestation;
upon depression thereof, said elastomeric material base cap operatively movable to a position which moves said shaft to provide access to dispensable material from said dispensable material containing or supporting structure at said first end of said housing;
and a stop mechanism within said housing for stopping movement of said generally central structure of said base cap so that upon continued depression of said base cap said first and second surface manifestations disconnect so that said dispensable material containing or supporting structure is removable from said housing and replaceable by a fresh dispensable material containing or supporting structure.
