초록 ▼

A self-adjustable roll-on liquid applicator having enhanced sealing features for containing and dispensing high volatility, low viscosity liquids. The applicator housing defines a discharge opening at its distal end for dispensing of contained liquid therefrom and a liquid-applying ball partially disposed in the housing distal end. An annular valve arrangement is disposed between the distal and proximal ends of the housing, thereby partitioning the housing into a ball retaining chamber and a valve-plug retaining chamber. A valve plug is movable into and out of abutment with an annular projection for regulating liquid flow between the ball retaining and valve-plug retaining chambers. The applicator also includes a spring in axial compressive engagement with the valve plug and ball for normally urging the ball into sealing abutment with a lip portion of the housing.

[ What is claimed is:] [1.] A ball-type roll-on applicator for dispensingly applying a low viscosity liquid to a work surface, comprising:an elongated housing having a distal dispensing end, a proximal end, a sidewall extending between said distal and proximal ends and defining a housing interior, and a radially-inwardly directed lip portion at said distal end defining a first valve seat and an applicator dispensing opening bounded by said first valve seat;an annular valve projecting radially-inward from said housing sidewall and defining a second valve seat and a third valve seat, said second valve seat being disposed more closely proximate said housing distal end than said third valve seat;said annular valve partitioning said housing interior into a first chamber at said housing proximal end for storing liquid for dispensed application to a work surface and a second chamber at said housing distal end, and said annular valve bounding a valve opening through which liquid is flowable between said first and second chambers;a valve member having a proximal end disposed in said first chamber, a distal end, and an engagement surface between said valve member distal and proximal ends;said valve member being disposed in said housing interior for movement between a first position in which said valve member engagement surface liquid-sealingly abuts said third seat to close said valve opening and thereby substantially prevent liquid flow between said first and second chambers, and a second position in which said valve member is displaced along the housing elongation toward said housing proximal end to space said valve member engagement surface from said third seat;spring means in said first chamber for normally resiliently urging said valve member into said first position and for providing a return urgency for resiliently returning said valve member from said second position to said first position; anda liquid-applying ball rotatively disposed in said housing distal end and captively retained against escape from said housing distal end by said lip portion, said ball having a peripheral surface for receiving stored liquid from the applicator and for applying the received liquid to a work surface through rolling contact of the ball surface with the work surface in an at least partly inverted orientation of the housing;said ball being rotatively supported on the distal end of said valve member for movement of said ball, as the ball is pressed against a work surface for dispensed application of liquid to the work surface and against the return urgency of said spring means, between(a) a first position in which said ball surface liquid-sealingly abuts said first valve seat and said valve member is disposed in said first position of the valve member so as to substantially prevent liquid flow between said first and second chambers and from said second chamber through and beyond said dispensing opening,(b) a second position in which said ball is displaced from said first position of the ball toward said housing proximal end to space said ball surface from said first valve seat and thereby permit transfer of liquid from the ball surface onto a work surface through said dispensing opening, and to displace said valve member from said first toward said second position of the valve member to thereby space said valve member engagement surface from said third valve seat and open said valve opening to permit liquid flow from said first chamber to said second chamber, and(c) a third position in which said ball is displaced from said second position of the ball toward said housing proximal end so that said ball surface liquid-sealingly contacts said second valve seat to close said valve opening and thereby prevent liquid flow between said first and second chambers, said ball surface in said third position of the ball being spaced from said first valve seat so as to permit transfer of liquid from the ball surface onto a work surface through said dispensing opening.
