Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to handled cleaning implements in general, and specifically to such implements having a cleaning liquid dispensing handle and a cleaning pad disposed at an end of the handle for receiving cleaning liquid dispensed therefrom.
2. The Prior Art
Handled cleaning implements are well known and commonly used household cleaning aids. Such implements typically comprise a gripping handle portion at one end and a cleaning pad or sponge mounted to an opposite end. The user grips the device by the handle and cleans a surface by means of the sponge end. A scraping blade is typically provided at a forward end to assist the user in certain cleaning tasks.
A useful enhancement to the conventional cleaning implement has been the development of a dispensing handle having an internal reservoir for the storage of liquid cleanser. The dispensing handle provides a through passageway at the remote sponge end through which the stored liquid cleanser is dispensed under the influence of gravity into the sponge member. The liquid cleanser can thereby be supplied continuously to the sponge and therefrom to any surface in contact with the sponge.
While the liquid dispensing handled implement described above represents an improvement over traditional devices, a serious shortcoming is that the discharge of liquid cleanser is continuous and unregulated. Consequently, it is typical that more liquid than is necessary becomes deposited on the sponge and is wasted. A second shortcoming is that the connection between the sponge member and the handle is not liquid tight, and leakage of the liquid can occur between the components. The result, again, is wasted cleaning liquid.
To solve the above deficiencies, improved liquid dispensing handled implements have been devised for regulating the quantity of liquid cleaner dispensed from the handle reservoir and for sealing the connection between the sponge and the handle member. U.S. Pat. Nos. 4,826,340 and 5,454,659 are representative of such improvements. The device in U.S. Pat. No. 5,454,659 comprises a handle and a sponge applicator. The handle includes a nipple at one end having a pinhole opening through which liquid flows from the handle reservoir. The sponge applicator attaches to the handle to form a liquid tight seal between the applicator and the outside circumference of the handle, and between the nipple and an opening in the support piece of the applicator. Excess liquid is thereby directed without leakage through the nipple and into the sponge. While this configuration prevents waste from escaping liquid, it does not allow the user to efficiently regulate the quantity of cleaning liquid is dispensed from the handle into the sponge member.
U.S. Pat. No. 5,454,659 provides a mechanism for controlling or regulating the volume of liquid discharged from the handle. The brush comprises a two housing halves, a brush body, and a valve member. The housing is formed as two symmetrically configured halves are attached and define therebetween a reservoir. The valve member is assembled within a groove of one half housing member and encaptured therein as the second half housing is attached to the first housing half. The valve is actuated by a slide mechanism to open and close an aperture in a lower portion of the housing member, whereby controlling the flow of liquid from the housing onto the brush body.
While the mechanism of U.S. Pat. No. 5,454,659 functions as intended to control the flow of liquid between the handle housing and the brush body, several deficiencies remain. First, four components are required, adding to the cost of manufacture. Moreover, the assembly of the four components is labor intensive and, accordingly, costly. Secondly, the assembly of the components is complicated by the requirement that the valve member be mounted within the reservoir of the handle housing. In addition, the handle housing itself is of relatively thick walled construction, necessitated by the functional demands thereon in housing and supporting the valve member, and by the functional provision of a scraping blade element at a forward end. The additional strength required in the handle housing, again, adds undesirable cost to the device. Finally, repair or replacement of the valve component is extremely difficult or impossible because the valve assembly is configured to house the valve element between the handle halves. In order to access the valve member, destruction of the handle would be necessary.
SUMMARY OF THE INVENTION
The present invention overcomes the aforementioned deficiencies in the prior art applicator devices by providing a two component assembly comprising a handle housing and an applicator attachment. The handle housing is formed of thin-walled plastic construction and includes an internal liquid reservoir and a discharge opening at a working end for allowing liquid to exit the reservoir. The applicator attachment comprises a molded plastic base plate of relatively thicker wall construction which releasably attaches to the handle housing. An applicator element, preferably a sponge or a plurality of brush bristles are affixed to one surface of the applicator attachment.
Integrally formed with the applicator attachment base plate is a valve member, comprising a molded plastic lever member and a molded plastic torsion spring. The lever member includes. a first forward extending arm having a stopper attached at a remote end, a second rearward extending arm, and a fulcrum portion between the first and second lever arms. The torsion spring is configured as a plastic arm supported at opposite ends by the base plate and a suspended mid-portion extending between the supported opposite ends. The fulcrum portion of the lever is pivotally attached to the mid-portion of the torsion spring and the lever member pivots between an unbiased first position in which the stopper is positioned away from the discharge opening and a biased second position in which the stopper is biased against the handle housing in sealing relationship to the discharge opening.
The applicator attachment base plate, valve member, and torsion spring are integrally formed as a one-piece unit, eliminating the need for assembly and resulting in economies of manufacture. The handle housing is molded as a one-piece unit and of thin-walled construction to conserve material. A scraping element is formed in the applicator attachment base plate at a forward end. The applicator attachment is releasably secured to the handle housing and can be removed and readily replace the attachment with another.
The lever member is digitally actuated to reliably seal the discharge opening in the handle housing, whereby giving the user control over the quantity of cleaning liquid discharged from the handle reservoir.
Accordingly, it is an objective of the subject invention to provide a liquid applicator implement having reliable means for controlling the quantity of liquid discharged.
A further objective of the invention is to provide a liquid applicator implement which has a minimal assembly requirement.
Still another objective is to provide a liquid applicator which provides a scraper element at a forward end.
Yet a further objective is to provide a liquid applicator which is readily refilled.
An additional objective is to provide a liquid applicator having minimal leakage.
A further objective is to provide a liquid applicator comprising a minimal number of component parts which individually are economically and readily manufactured, and which are economically and readily assembled.
These, and other objectives, which will be appreciated by one skilled in the art, are achieved by a preferred embodiment which is described in detail below and illustrated in the accompanying drawings.

74
; and a rib-receiving channel
100
extending into surface
74
, commencing at the spring receiving channel
98
and thence extending forward to the central depression
86
.
From a combined consideration of
FIGS. 1
,
2
,
5
, and
6
, it will be appreciated that manufacture and assembly of the subject applicator device is as follows. The sponge member
12
is independently formed of cellulose or polyester material. Alternative materials suitable for cleaning applications may be substituted. In addition, other applicator surfaces may be utilized within the scope of the present invention. For example, a plurality of brush bristles may be affixed to the underside of base plate
14
if so desired, or, without limitation, a polishing or cleaning cloth may be secured. In short, the application and the fluid to be applied to a surface or article will determine the configuration of the applicator side of the base plate
14
.
The sponge
12
, in the preferred embodiment, is attached by heat fusion to the base plate
14
underside, and resides within cavity
34
, secured to lowermost edge
40
and the lower edges of reinforcement ribs
36
. As explained previously, the base plate
14
is unitarily molded of conventional plastics material by conventional means, such as by injection molding. The base plate is formed in include an integral valve, represented by the actuation lever
42
, the stopper
56
, and the torsion springs
58
,
60
. The aforementioned components, which comprise the valve, are integrally formed with the body of the base plate
14
of the same material and by the same process.
As best seen in
FIGS. 5 and 6
, the stopper
56
is affixed by a suitable commercially available adhesive to the stopper end portion
54
of the lever closure arm
48
, between protruding flanges
55
a, b
, and
c
. The base plate
14
attaches to the nose portion
72
of the handle
16
. Nose flange
78
fits within opening
64
of the base plate
14
and is captured. Thereafter, surface
74
is moved downward between plate rim flange
22
and against surface
18
. Aligned locking arms, or flanges,
26
,
28
, align with the depressions
80
,
82
, respectively, of nose portion
72
of handle
16
and the locking lip
30
of each rides over the locking ledge
84
within each depression
80
,
82
to releasably attach the base plate
14
to the handle nose portion
72
. The locking arms
28
,
30
, being formed as cantilevers of plastic material, resiliently flex outward to ride up and over the depression locking ledges
84
during attachment, and flex outward under manual influence to disengage the locking lip
30
from its respective ledge
84
, whereby allowing the base plate
14
to separate from the handle nose portion
72
.
In the attached position, the rib
52
of the lever
42
resides within channel
100
of the nose portion
72
; the torsion springs
58
,
60
and fulcrum portion
53
reside with the transverse channel
98
; and lever trigger arm
44
resides within channel
96
.
Moreover, in the attached position, the stopper
56
aligns opposite and seats within the depression
86
of the handle nose portion
72
and, therein, engages against the top surface
90
. As the stopper
56
bears upon the circular shoulder
92
as shown in
FIG. 6
, it creates a liquid tight seal thereagainst, whereby blocking liquid from escaping from reservoir
68
by passage
94
. The torsion spring members
58
,
60
are in a quiescent, or unloaded, state when the stopper
56
in a closed relationship against surface
92
. Resistance provided by the torsion spring members
58
,
60
to loading acts to maintain the liquid tight seal between the stopper
56
and surface
90
.
The load required to open the lever
42
is manually applied by digitally pressuring the trigger portion
44
toward handle
66
, causing pivoting of the lever
42
about fulcrum
53
and lever arm
48
to pivot away from the handle nose portion
72
. Such pivotal movement lifts the stopper
56
away from surface
90
and breaks the seal, allowing liquid to escape reservoir
68
through passageway
94
. The escaping liquid flows downward about the lever arm
48
, through U-shaped opening
32
in the base plate
14
, and onto the back side of the sponge
12
. From there it is distributed throughout the sponge and onto a surface against which the sponge
12
is pressed.
It will be noted that soap, or the liquid within handle
16
, is dispensed at will by pressing the exposed rearward trigger portion
44
of the lever toward the handle
66
. When the lever is pressed towards the handle, the opposite end of the lever
42
, arm
48
, moves away from the handle, exposing passageway
94
and allowing soap to leak into the sponge. Once the desired quantity of soap is dispensed, and the lever trigger portion
44
is released, the lever
42
will spring back to the closed position.
The load required to open the lever, and the automatic closing of the valve is caused by the two torsion springs
58
,
60
located on either side of the lever fulcrum portion
53
. The springs
58
,
60
are substantially cylindrical, of circular cross-section. Outward ends of the spring members
58
,
60
are integrally formed with sides of the base plate. Accordingly. the lever, torsion springs, and the base plate are a continuous, integrally formed piece of plastic.
The normal, quiescent state of the torsion springs is when the lever is in the closed position. When pivoted into the open position, the lever
42
causes the torsion springs
58
,
60
to undergo a moment loading. Potential energy is stored in the torsion springs until the lever arm
44
is released, the energy is released to cause a reverse pivoting of the lever
42
and stopper
56
reassumes a sealing engagement against the nose portion of the arm.
The base plate
14
and sponge
12
can be sold separately as a replacement attachment. Because the scraper blade or edge
62
is an integral part of the replacement attachment, a new scraper is provided with each replacement. Additionally, the handle member
16
can be formed of thin wall construction because the thicker material needed for creation of the scraper blade
62
is provided by the base plate
14
. Since base plate
14
is a physically smaller component than the handle member
16
, positioning the blade
62
on the attachment applicator results in substantial material savings.
The base plate, from the foregoing, provides a combination of functional objectives. It acts as an applicator implement, supporting the sponge
12
or other applicator surface on one side for application purposes. Plate
14
further serves as a base plate for the scraper blade
62
which is integral therewith. Replacement of the applicator attachment automatically results in a replacement of the scraper element integral therewith.
Finally, the base plate
14
provides an integrally formed valve for selectively opening and closing the flow of liquid from the handle reservoir. Positioning the valve on the base plate member, as with the scraper, causes the valve element to be replaced each time the applicator attachment is replaced. This preventative replacement means the applicator will function as intended through prolonged use. Moreover, the valve is integrally formed with the base plate as a single body. The cost of manufacture is, resultingly, low and there is no additional assembly cost involved in assembling the valve to the applicator implement. Prior art devices which require assembly of the valve to the handle component not only introduce an additional component, increasing cost, but also add an additional assembly step which, again, results in an increased cost of manufacture.
While the above describes a preferred embodiment of the subject invention, the scope of the invention is not intended to be so restricted. Other uses of the teachings herein set forth are intended to be within the scope and spirit of the invention. By way of example, without any restriction being intended, the subject applicator may be adapted for use in non-cleaning applications. Liquid, other than fluid cleaning soap, may be stored within the reservoir and applied through the base plate
14
to other types of applicator elements for application to a surface. Liquid adhesives, or liquid wax, for example, may be so applied.
In addition, the base plate and integral valve taught herein have applications, which will be apparent to one skilled in the art, beyond the preferred use set forth. The valve and base plate, integrally formed, may be useful in may applications where controlled fluid flow from a reservoir is required. Beverage dispensers can be constructed having a similar valve arrangement as instructed herein without departing from the intended scope of the invention.
