Abstract

Abstract A liquid applicator includes a combined liquid container and handle with an axially extending, liquid permeable sleeve. An elongated tube having apertures throughout its length provides internal support for the sleeve and valve means provides controlled flow of the liquid from the container, through the tube and to the permeable sleeve. In another embodiment the applicator consists of an elongated arm having an applicator head at one end, the other end having a threaded or snap connection for attachment to a squeeze type container. A plastic tube extends from the head to the container attachment and is enclosed by the arm.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 297 words
An applicator for applying liquid to a person's body, comprising: a storage container for the liquid to be applied, said storage container having an aperture defined in an upper end thereof and a neck portion with a threaded outer surface; an elongated, fluid transmission tube including walls extending axially upwardly from said upper end of said container said tube having a lower end with a threaded inner periphery for engaging the threaded outer surface of the neck portion of said storage container and a plurality of apertures defined in the walls thereof for passage there through of liquid from the interior of said tube; sponge means for receiving liquid from said tube and including a liquid permeable sleeve coaxially mounted on and supported by said elongated tube, said sponge means enveloping substantially the full length of said tube; and valve means for controlling flow of liquid from said container to said tube and including a disc detachably coupled to the lower end of said tube and having a plurality of openings defined therein and a stem portion depending from said disc for cooperation with said aperture in the upper end of said storage container so that rotation of the lower end of said tube on its threaded connection with said container neck, raises or lowers said stem portion into or out of engagement with said aperture and wherein said lower end of said tube further includes a frusto-conical section intermediate the threaded portion thereof and the portion supporting said sponge means and a peripheral channel formed in said frusto-conical section and wherein said disc further includes a frusto-conical wall portion in surface contact with said frusto-conical section of said tube and a peripheral rim snap-fitted into said channel whereby said valve means is quickly detachable for cleaning.
Claim 2
Dependent Claim 297 words
An applicator for applying liquid to a person's body, comprising: a storage container for the liquid to be applied, said storage container having an aperture defined in an upper end thereof and a neck portion with a threaded outer surface; an elongated, fluid transmission tube including walls extending axially upwardly from said upper end of said container said tube having a lower end with a threaded inner periphery for engaging the threaded outer surface of the neck portion of said storage container and a plurality of apertures defined in the walls thereof for passage there through of liquid from the interior of said tube; sponge means for receiving liquid from said tube and including a liquid permeable sleeve coaxially mounted on and supported by said elongated tube, said sponge means enveloping substantially the full length of said tube; and valve means for controlling flow of liquid from said container to said tube and including a disc detachably coupled to the lower end of said tube and having a plurality of openings defined therein and a stem portion depending from said disc for cooperation with said aperture in the upper end of said storage container so that rotation of the lower end of said tube on its threaded connection with said container neck, raises or lowers said stem portion into or out of engagement with said aperture and wherein said lower end of said tube further includes a frusto-conical section intermediate the threaded portion thereof and the portion supporting said sponge means and a peripheral channel formed in said frusto-conical section and wherein said disc further includes a frusto-conical wall portion in surface contact with said frusto-conical section of said tube and a peripheral rim snap-fitted into said channel whereby said valve means is quickly detachable for cleaning.
Claim 3
Dependent Claim 12 words
Apparatus according to claim 1, wherein said container has a removable bottom.
Claim 4
Dependent Claim 51 words
