Abstract
Description
- The present invention relates to cleaning devices and, in particular, to such devices which carry and dispense cleaning fluid. The invention relates in particular to a soap-dispensing brush.
- Prior soap-dispensing cleaning devices are known, which include a housing defining a soap-containing reservoir, with a wall of the housing carrying a cleaning medium, such as a sponge, brush or the like. A valve assembly dispenses fluid from the reservoir to the cleaning medium. In one such device the valve assembly includes a stem which extends upwardly through an opening in a cap which closes the upper end of the reservoir. While such devices are able to dispense soap to the cleaning medium, they are either expensive and complex to manufacture or have valve actuating mechanisms that operate inefficiently. Such devices may also have a flexible pump button in order to activate the valve. However, a depressed pump button may remain in a deflected position, causing the apparatus to be inoperable.
- It is a general object of the invention to provide an improved fluid-containing cleaning device which avoids the disadvantages of prior such devices while affording additional structural and operating advantages.
- An important feature of the invention is the provision of a fluid-containing cleaning device of the type set forth, which has a manually-actuated resilient button for actuating a fluid-dispensing valve assembly via increase of pressure within the reservoir by movement of the button between a rest position and a depressed position.
- In connection with the foregoing feature, another feature of the invention is the provision of a device of the type set forth having a resilient button including a bias member for returning the button to a rest position.
- Still another feature of the invention is the provision of a device of the type set forth, which is of simple and economical construction.
- Certain ones of these and other features of the invention may be attained by providing a fluid-containing cleaning device comprising: an open housing defining a fluid reservoir, a cleaning medium carried by the housing, a valve carried by the housing for providing communication between the reservoir and the cleaning medium, a closure structure closing the opening, a flexible and resilient actuator deflectable between a rest position and an actuating position and a bias structure disposed adjacent to the actuating member so that upon depression of the actuating member, the bias structure will return the button to its rest position.

numeral 10, constructed in accordance with and embodying the features of the present invention. Thecleaning device 10 is in the nature of a liquid soap-fillable brush, but it will be appreciated that the present invention is applicable to cleaning devices with other types of cleaning media, such as sponges, pads or the like. FIG. 1 depicts the general features of the cleaning device and FIGS. 2-12 depict alternate embodiments thereof. Like numerals will be used in all of the FIGS., to designate like elements. - The
cleaning device 10 has ahousing 11 which includes a generallycylindrical side wall 12, in an embodiment formed of a transparent or translucent material, such as a suitable polymer. In an embodiment, theside wall 12 forms a top opening 9 and thewall 12 has a radially inwardly projectingcircumferential depression 13 formed therein intermediate the upper and lower ends thereof, which can serve as a finger grip to facilitate grasping of the device by a user's hand. Theside wall 12 is provided at its upper end with an annular shoulder and an upwardly projectingcylindrical collar 15. - In an embodiment, the
collar 15 is externally threaded and includes aspiral thread 16. In an alternate embodiment other coupling means may be provided, for example, short rectangular lugs may project radially outwardly from the upper end ofcollar 15 at equiangularly spaced locations. Anannular groove 17 is formed in the lower end of theside wall 12 and is adapted to receive therein acylindrical flange 19 projecting axially from theannular end face 18 of abase 20, which may be formed of a suitable polymer material.

Fixedly secured to the outer surface of thebase 20 is asuitable cleaning medium 25 which, in the illustrated embodiment, comprises a plurality of brush bristles (FIG. 1), which may be fixed in sockets in thebase 20 by any suitable means. It will be appreciated that theaxial bore 24 provides communication between a reservoir formed in an interior of thehousing 11 and thecleaning medium 25. Mounted in thebore 24 is a valve assembly including aretaining ring 26 that receives avalve 28 therein. In an embodiment, the valve assembly may operate as described in any of U.S. Patent Nos. 5,439,143; 5,409,144; 5,377,877; 5,339,995; 5,213,236; 5,033,655 or 4,991,745, each of which is incorporated herein by reference. - The
device 10 includes aclosure structure 40 including acap 45 disposed therein. In an embodiment, thecap 45 is rigid and is generally part-dome-shaped and includes a generallycylindrical skirt portion 46.

resilient member 51. In an embodiment, theresilient member 51 covers the entire outer surface of thecap 45 and includes an actuator orbutton 50 that spans and closes the opening 48, 49. In an embodiment, theclosure structure 40 includes thebutton 50 formed thereon. In an alternate embodiment, thebutton 50 may be formed separate from theclosure structure 40 and thecap 45. In an embodiment, theresilient member 51 is formed of a suitable elastomeric material and is fixedly secured to the outer surface of thecap 45 by any suitable means, such as insert molding. In an embodiment, thebutton 50 is preferably integrally molded with theresilient member 51. In an embodiment, acircular groove 53 is formed between thebutton 50 and the remainder of theresilient member 51 to facilitate flexing of thebutton 50. In an embodiment, it can be seen that thebutton 50 completely encloses theopening opening button 50 andresilient member 51 which may be formed of an elastomeric material, such as that sold under the trademark "SANTOPRENE", also provides a frictional non-slip surface to improve the grip by a user's hand. In an embodiment, thebutton 50 is oriented at the pole or vertex of theresilient member 51. In an embodiment, thebutton 50 is convex. In alternate embodiments, the button may be flat or concave. - In use, the
cap 45 is fitted onto the upper end of thehousing 11, with thethread 16 threadedly engaging thethread 47. Upon rotation of thecap 45, relative to theside wall 12, theclosure structure 40 is securely held in place for cooperation with thehousing 11 to define and close afluid reservoir 55, which is fillable with a suitable cleaning fluid, such as a liquid soap. It will be appreciated that thecap 45 could also be removably attached to thehousing 11 by other means. The flexible and resilient nature of thebutton 51 of theresilient member 50 accommodates easy manual actuation of theactuator button 51 from above thecap 45. When thecap 45 is secured in place, the threadedskirt 46 forms a fluid-tight seal between thecap 45 and thehousing 11. It is also appreciated that in an alternate embodiment, thecap 45 andmember 50 may be formed of one-piece to provide an integral resilient andflexible closure structure 40. - Turning to the alternate embodiments disclosed by FIGS. 2-14, 5-7 and 8-12, each of the alternate embodiments function similarly and have the same components as discussed above except for a bias assembly which will now be described for each of the embodiments. Turning to FIGS. 2-4, a bias assembly 60 is depicted, which includes a
bias structure 61 and a retainingplate 62. In an embodiment, thebias structure 61 may be a coil spring. In an embodiment, the coil spring may be formed of metal, polymer or other suitable material. In an embodiment, the retainingplate 62 is cylindrical in shape and includes aflange 63, abody 64 and asupport member 65 attached to thebody 64. Thebody 64 defines acylindrical opening 66 which receives thebias structure 61 therein. In an embodiment, thesupport member 65 hassupport arms 67a, b, c, d extending from acenter panel 68. In an embodiment, acylindrical cup 69 is disposed on thepanel 68. In an embodiment, aknob 71 protrudes from thepanel 68 and is surrounded by thecylindrical cup 69 to form achannel 72 therein. Thecylindrical channel 72 receives an end of thebias structure 61 so that the coils of the bias member are securely mounted so that the end of thebias structure 61 is restricted from lateral movement. In an embodiment, the diameter of theknob 71 is approximately equal to the inner diameter of the coils of thebias structure 61. - The
button 50 includes aninterior wall 75. In an embodiment, acollar 76 protrudes from theinterior wall 75. In an embodiment, the collar may be integrally formed with theresilient member 51. In an embodiment, thecollar 76 has an outer diameter that is approximately equal to the inner diameter of the coil spring of thebias structure 61 and receives the coil spring thereon. Therefore, as shown in FIG. 2, it may be understood that a first end of the coil spring is mounted to theknob 71 and received in thechannel 72 and a second end of thebias structure 61 is mounted onto thecollar 76 of thebutton 50. By trapping thebias member 61 between theinterior wall 75 and the retainingplate 62, the bias member is securely held in place and will provide a strong bias force in order to return thebutton 50 to its rest position (as shown in FIGS. 2 and 3) after being depressed in order to pressurize thereservoir 55. Therefore, it is understood that a user may manually deflect thebutton 50 by pushing downward, which will compress thebias member 61.
