Benefits of technology
[0015]The cost of producing these devices is low, notwithstanding that they can reliably meter desired amounts of liquid to the surface being treated, and then work the liquid against the surface. Further, in some embodiments they permit the nature of the product to be displayed to the consumer at the time of sale, while still protecting the pad from vandalism and minimizing the risk of leakage. In other embodiments the invention provides a convenient way of storing the applicator between uses, even after the pad has become partially dirtied.
Problems solved by technology
A disadvantage of many such devices is that they sometimes deliver too much liquid (e.g. creating a drool or waste problem), or deliver too little liquid (e.g. especially if the pad is susceptible to being clogged).
Further, some of these devices are complex to construct and thus unduly costly.
Some are also susceptible to vandalism when being displayed in a store.

Embodiment Construction
[0029]Referring first to FIGS. 1-3, a preferred embodiment liquid applicator 10 of the present invention is shown. The applicator 10 has a fluid reservoir 12 in the form of a squeeze bottle, an adapter 14 in the form of a neck, and a scrubber 18 housed in a “blister” type pack 16.
[0030]The applicator 10 can be displayed on a store shelf or stored in a home upright, as shown in FIG. 1. Prior to use pack 16 must be removed from the pad 18, with the pad 18 then being re-connected to the adapter 14. Then, the applicator 10 can be inverted so that the pad 18 will press against the surface 48 to be cleaned as shown in FIG. 7.
[0031]Reservoir 12 is but one possible reservoir form. As shown in FIGS. 10-12, the reservoir can instead be a reservoir 12A in the form of a molded handle.
[0032]As seen in FIG. 5 the adapter 14 has a centrally-located, axially extending opening 24 in communication with liquid in the reservoir 12. The opening 24 is bordered on two sides by protruding, L-shaped legs 26...

Abstract
Disclosed are liquid applicators for dispensing liquid to a surface such as a bathroom wall, and working the liquid against the surface. The applicators may have a compressible reservoir for the cleaning liquid. Upon compressing the reservoir the liquid is driven to a scrubbing pad in a controlled fashion. A check valve prevents back flow to the reservoir from the pad. A blister pack can house the scrubbing pad even when the pad is attached to the reservoir. In another form the applicator can be tipped and rested on its side between uses.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH / DEVELOPMENT[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]The present invention relates to compact hand-held devices that both provide liquid and the capability of working the liquid against a surface to which the liquid is being applied. It also relates to display / storage packaging useful therewith.[0004]A variety of liquid applicators have been developed that have a reservoir to store a fluid to be applied and an applicator head / pad. See e.g. U.S. Pat. Nos. 2,820,234, 2,932,840, 3,135,990, 3,148,401, 3,565,294, 3,653,779, 4,183,684, 4,201,491, 4,553,871, 4,652,163, 4,961,661, 4,983,061, 5,114,255, 5,397,194, 5,454,659, 5,908,256, 6,036,391, 6,210,064, 6,425,701, 6,817,801, and 6,945,722. The disclosure of these patents, and of all other patents referred to herein, are incorporated by reference as if fully set forth herein.[0005]Some of these prior devices use a trigg...
