Rinsing of a cleaning medium in the bucket according to the invention is controlled through use of the cleaning medium actuating the wringer receptacle. The storage reservoir may also comprise a valve that can be actuated by movement of the wringer receptacle.
Description
BUCKET FOR HANDLING LIQUIDS
The present invention claims priority of US provisional patent applications 601892,634 filed March 2, 2007 and 60/939,078 filed May 20, 2007, the contents of which are incorporated herein by reference.
FIELD OF THE INVENTION
The present invention generally relates to cleaning products. More particularly, it relates to a cleaning bucket for handling liquids.
BACKGROUND OF THE INVENTION
In basic cleaning buckets, the mop is immersed in the clean wash solution and, in so doing, contaminates the clean wash solution by direct contact with the dirty mop. The cleaning medium is thus repeatedly rinsed in soiled wash solution from previous soakings and wringings. This results in the spreading of soiled or dirty wash solution on the surfaces to be cleaned.
This method of cleaning is counter-productive and not optimal since contaminated water is then used for cleaning tasks.
There exist a certain number of multi-compartmented cleaning buckets that have been developed as improvements over the basic cleaning bucket (with a single compartment). Such buckets provide for separate containment of the dirty wash liquid and the clean wash soiution which are isolated from each other.
U.S. Patent no. 4,798,307 describes a compartmented cleaning bucket.
However, in such a system, discharge of the cleaning wash liquid into a discharge transfer compartment is not easily controlled by the user.

U.S. Patent no. 4,798,307 describes a compartmented cleaning bucket.
However, in such a system, discharge of the cleaning wash liquid into a discharge transfer compartment is not easily controlled by the user.
U.S. Patent no. 3,045,252 describes another compartmented cleaning bucket in which discharge of the clean wash liquid into a transfer compartment is controlled with a valve. However, a user must constantly open and close the valve manually in order to rinse the mop in a clean liquid solution.
Other bucket systems known to the applicant are described in http://www.limpieza.com/busca_docs.asp?id=612, and in the following patents or patent applications WO 0000077, EP 0,956,807, US 5,548,865, US 6,006,397, US 6,260,230, US 6,279,195 and US 6,457203.
Thus, there is still presently a need for a bucket that can control the amount of clean wash solution being applied on the cleaning medium (mop, sponge or any other item) while isolating the soiled water from the clean wash solution. The control has to be easily accomplished by the user without necessarily having to release the cleaning medium being rinsed or wringed. Such a bucket would allow for efficient and hygienic cleaning tasks using a clean wash solution only and thus reduce the spreading of soiled water on the surfaces to be cleaned in an efficient manner.
SUMMARY OF THE INVENTION
An object of the present invention is to propose a bucket that satisfies the above-mentioned need.
More particularly, the present invention provides a bucket for handling liquids comprising:
-a collector reservoir;
-a wringer receptacle comprising:
-a collector outlet in fluid communication with the collector reservoir; and -a storage reservoir comprising at least one discharge aperture.

SUMMARY OF THE INVENTION
An object of the present invention is to propose a bucket that satisfies the above-mentioned need.
More particularly, the present invention provides a bucket for handling liquids comprising:
-a collector reservoir;
-a wringer receptacle comprising:
-a collector outlet in fluid communication with the collector reservoir; and -a storage reservoir comprising at least one discharge aperture.
The wringer receptacle is positionable between a first position wherein the wringer receptacle blocks the at least one discharge aperture and a second position wherein the wringer receptacle allows fluid communication between the storage reservoir and the wringer receptacle through the at least one discharge aperture.
The present invention also provides a bucket for handling liquids comprising:
-a collector reservoir;
-a wringer receptacle comprising:
-a collector outlet in fluid communication with the collector reservoir; and -a biasing structure;
and -a storage reservoir comprising:
- a discharge aperture; and -a spring valve closing the discharge aperture.
The wringer receptacle is positionable between a first position wherein the wringer receptacle biasing structure allows fluid communication between the storage reservoir and the wringer receptacle through the at least one discharge aperture by actuating the spring valve, and a second position wherein the wringer receptacle biasing structure releases the spring valves and blocks fluid communication between the storage reservoir and the wringer receptacle.
Such a cleaning bucket eliminates wash solution contamination which typically occurs after the wringing, rinsing or soaking of a cleaning medium (mop, sponge, cloth or any other item) in the wash solution. This is achieved by metering of the wash solution into the wringer receptacle for the cleaning medium. This allows for an improved cieaning process which yields cleaner surfaces since the wash solution used for cleaning remains always clean and contaminant free.
The present invention represents an improvement over other compartmented cleaning buckets because the cleaning medium, such as a mop head, never enters in the clean wash solution compartment. The clean wash solution flows on the mop head directly into the wringer receptacle. This prevents clean wash solution contamination and therefore prevents contaminated wash solution from being deposited over and over again on the target surfaces to be cleaned.
Similarly, the present invention facilitates cleaning tasks by not requiring several replacements of the wash solution which normally becomes soiled after a certain number of soakings of the cleaning medium. The design also minimizes movement or displacements of the cleaning medium since rinsing and wringing are carried out in a same location, the wringer receptacle. Rinsing can also be controlled through use of the cleaning medium itself.
The present invention also has an environmental benefit as less water is required to perform the cleaning task since no replacement of the wash solution is required. Moreover, a smaller amount of wash solution is required in the first place.
The present invention also represents a simple mechanical solution as it has only one principal moving part and is inexpensive to manufacture.
A non-restrictive description of preferred embodiments of the invention will now be given with reference to the appended drawings.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to any one of figures 1A to 18B, a bucket 10 for handling liquids according to a first embodiment of the present invention is shown.
According to the present invention, as shown in Figures 2A and 2B, the bucket 10 comprises a collector reservoir 12 and a wringer receptacle 14.
The wringer receptacle 14 has a collector outlet 18 in fluid communication with the collector reservoir 12. The bucket also comprises a storage reservoir 16 having at least one discharge aperture 20. The aperture 20 is better illustrated in Figures 8A and 8B. The wringer receptacle 14 is positionable between a first position (shown in Figure 2A) wherein the wringer receptacle 14 blocks the discharge aperture 20 and a second position (shown in Figure 2B) wherein the wringer receptacle 14 allows fiuid communication between the storage reservoir 16 and the wringer receptacle 14 through the discharge aperture 20.
Preferably, the wringer receptacle 14 is rotatably positionable between the first position and the second position.
In another embodiment of the present invention, the bucket 10 preferably comprises a spring mechanism for biasing the wringer receptacle 14 towards the first position.
Preferably, as shown in Figures 14A to 14E, the storage reservoir 16 is removably attached to the bucket. In another embodiment of the present invention, the storage reservoir may be integral to the collector reservoir.
Preferably, the storage reservoir comprises a first floor surface, the wringer receptacle comprises a second floor surface, the collector reservoir comprises a third floor surface, the first floor surface is higher than the second floor surface and the second floor surface is higher than the third floor surface. This implies that liquids in the bucket flow through gravitational effects from the storage reservoir, to the wringer receptacle and then to the collector reservoir.
Preferably, the wringer receptacle 14 comprises at least one fluid inlet aperture 22 and the at least one fluid inlet aperture 22 is in register with the at least one discharge aperture 20 when the wringer receptacle 14 is in the second position as shown in Figures 9A to 9B.
Preferably, as shown in Figures 16A to 17B, the storage reservoir 16 further comprises at least one spring valve 26 closing the at least one discharge aperture.
5 As shown in Figures 17A and 17B, the wringer receptacle preferably comprises a biasing structure 28. As mentioned previously, the storage reservoir may comprise a discharge aperture 20 and a spring valve 26 closing the discharge aperture 20. Hence, the wringer receptacle 14 is positionable between a first position (shown in Figures 17A and 17B) 10 wherein the wringer receptacle biasing structure 28 allows fluid communication between the storage reservoir 16 and the wringer receptacle 14 through the discharge aperture 20 by actuating the spring valve 26, and a second position (shown Figures 16A to 16C) wherein the wringer receptacle biasing structure 28 releases the spring valve 26 and blocks fluid communication between the storage reservoir 16 and the wringer receptacle 14.
Operational Use of the Bucket Similar to conventional mop and bucket systems, a user may start a mopping task by filling the storage reservoir 16 with a desired cleaning solution. In a first embodiment of the present invention, the storage reservoir has a capacity of 10 L (2.64 Gallons). Once this is accomplished, the operation can be broken down into two phases: mop rinsing and mop wringing.
Mop Rinsing The mop head 50 (rectangular sponge-type mop or round-type threaded mop) is positioned in the wringer receptacle 14 as shown in Figure 3. The wringer receptacle may have an inscription "OPEN" where the mop head is to be placed. A downward force is then applied on the wringer receptacle 14 by applying a downward pushing force on the mop handle 52.
As shown in Figures 2A and 2B, this will impose a 20 degree rotation of the wringer receptacle. This moves away any structure located in front of the storage reservoir 16 aperture 20 and sealing structure 58. The mop is soaked and rinsed by 13 jets of flowing cleaning solution until the desired level of rinsing is achieved as shown in Figure 4. Any excess cleaning solution is automatically drained by gravity through drain openings 54 to the collector reservoir 12. There is also a pooling effect of clean wash solution accumulating in the wringer receptacle 14. Pool water is drained when wringer receptacle 14 is rotated back to the closed flow position.
Mop Wringing Wash solution flow into the wringer receptacle is interrupted by applying a downward force on the wringer receptacle 14, on the face where drain openings 54 are located. This will impose a 20 degree rotation of the wringer receptacle in a direction opposite the mop rinsing procedure, aligning back the blocking structure located on the wringer receptacle 14 in front of the outlet aperture 20. Mop wringing is also accomplished within the wringer receptacle by the same downward motion of the mop releasing excess solution into the collector reservoir 12 by gravity. The mop can now be lifted from the bucket and is ready for cleaning tasks.
As shown in Figures 6A and 6B, the wringer receptacle 14 preferably comprises a built-in mop wringing receptacle 56.
As shown in Figures 7A to 7C, the storage reservoir 16 preferably comprises for sealing purposes two .210" cross section 0-rings 58 installed in grooves on the storage reservoir 16.
Figure 34 is a partially-cut perspective view of a bucket according to another embodiment of the present invention;
Figures 35A and 35B are cross-sectional views of the bucket shown in Figure 34 in a closed flow configuration and an open flow configuration;
Figures 36A and 36B are bottom perspective and detailed views respectively of the storage reservoir and the wringer receptacle of the bucket shown in Figure 34;
Figures 37A to 37D are perspective, front, side and top views respectively of a bucket according to another embodiment of the present invention;
Figures 38A and 38B are partially cut and detailed views respectively of the bucket shown in Figure 37A in an open flow configuration.
Figures 39A and 39B are perspective and top views of a wringer receptacle according to another preferred embodiment of the present invention.
Figures 40A and 40B are side views in a closed flow position and an open flow position of the wringer receptacle shown in Figures 39A and 39B.

Preferably, as shown in Figures 16A to 17B, the storage reservoir 16 further comprises at least one spring valve 26 closing the at least one discharge aperture.
5 As shown in Figures 17A and 17B, the wringer receptacle preferably comprises a biasing structure 28. As mentioned previously, the storage reservoir may comprise a discharge aperture 20 and a spring valve 26 closing the discharge aperture 20. Hence, the wringer receptacle 14 is positionable between a first position (shown in Figures 17A and 17B) 10 wherein the wringer receptacle biasing structure 28 allows fluid communication between the storage reservoir 16 and the wringer receptacle 14 through the discharge aperture 20 by actuating the spring valve 26, and a second position (shown Figures 16A to 16C) wherein the wringer receptacle biasing structure 28 releases the spring valve 26 and blocks fluid communication between the storage reservoir 16 and the wringer receptacle 14.
Operational Use of the Bucket Similar to conventional mop and bucket systems, a user may start a mopping task by filling the storage reservoir 16 with a desired cleaning solution.

As shown in Figures 2A and 2B, this will impose a 20 degree rotation of the wringer receptacle. This moves away any structure located in front of the storage reservoir 16 aperture 20 and sealing structure 58. The mop is soaked and rinsed by 13 jets of flowing cleaning solution until the desired level of rinsing is achieved as shown in Figure 4. Any excess cleaning solution is automatically drained by gravity through drain openings 54 to the collector reservoir 12. There is also a pooling effect of clean wash solution accumulating in the wringer receptacle 14. Pool water is drained when wringer receptacle 14 is rotated back to the closed flow position.
Mop Wringing Wash solution flow into the wringer receptacle is interrupted by applying a downward force on the wringer receptacle 14, on the face where drain openings 54 are located. This will impose a 20 degree rotation of the wringer receptacle in a direction opposite the mop rinsing procedure, aligning back the blocking structure located on the wringer receptacle 14 in front of the outlet aperture 20. Mop wringing is also accomplished within the wringer receptacle by the same downward motion of the mop releasing excess solution into the collector reservoir 12 by gravity. The mop can now be lifted from the bucket and is ready for cleaning tasks.
As shown in Figures 6A and 6B, the wringer receptacle 14 preferably comprises a built-in mop wringing receptacle 56.
As shown in Figures 7A to 7C, the storage reservoir 16 preferably comprises for sealing purposes two .210" cross section 0-rings 58 installed in grooves on the storage reservoir 16.
Figures 8A and 8B illustrate sealing with the wringer receptacle 14 in the closed position. A face seal is created between the wringer receptacle 14 side surfaces and the 0-ring 58.
Figures 9A to 9C illustrate sealing with the wringer receptacle 14 in the open flow position. In this configuration, the wringer receptacle manifold openings 60 are aligned with storage reservoir apertures 20.
Figures 10A and 10B show wringer receptacle rotation stop structures 62 with the wringer receptacle 14 in the open flow position. In this configuration, collector reservoir 12 cavities act as wringer rotation stops.
Figures 11A and 11B show wringer receptacle rotation stop structures 64 with the wringer receptacle 14 in the closed position. In this configuration, collector reservoir 12 cavities act as wringer rotation stops.
Figures 12A to 13B illustrate how the wringer receptacle 14 can be snap fitted onto the collector reservoir 12 through appropriate interfaces.
Figures 14A to 15B illustrate how the storage reservoir can be snap fitted onto the collector reservoir 12 through appropriate interfaces.
Preferably, as shown in Figures 16A to 18B, as an option, the storage reservoir 16 comprises a self-closing valve 26 having a spring 66.
As shown in Figures 16A to 16C, the storage may be removed from the bucket assembly for filling, thus placing the valve 26 in a closed position.
Then, when the storage reservoir is placed in the bucket, the valve 26 is opened as shown in Figures 17A and 17B.
To allow flow between the storage reservoir 16 and the wringer receptacle 14, the wringer receptacle fluid inlet aperture 22 is placed in register with the storage reservoir discharge aperture 20 as shown in Figures 18A and 18B.

Figures 14A to 15B illustrate how the storage reservoir can be snap fitted onto the collector reservoir 12 through appropriate interfaces.
Preferably, as shown in Figures 16A to 18B, as an option, the storage reservoir 16 comprises a self-closing valve 26 having a spring 66.
As shown in Figures 16A to 16C, the storage may be removed from the bucket assembly for filling, thus placing the valve 26 in a closed position.
Then, when the storage reservoir is placed in the bucket, the valve 26 is opened as shown in Figures 17A and 17B.
To allow flow between the storage reservoir 16 and the wringer receptacle 14, the wringer receptacle fluid inlet aperture 22 is placed in register with the storage reservoir discharge aperture 20 as shown in Figures 18A and 18B.
Wash Solution Disposal Once the mopping task is completed, the wash solution is disposed of by first emptying the excess water solution located in the storage reservoir 16 into the collector reservoir 12. This is accomplished by opening the wringer valve (as is done in the mop rinsing phase) to allow drainage into the collector reservoir. With all the solution now located in the collector reservoir 12, the bucket may be tilted to allow the fluid to flow out through a collector reservoir spout 70 (shown for example in Figures 1 B and 1 C).
The above-mentioned first embodiment of the present invention is compatible with rectangular sponge type mops, traditional yarn mops, sponges, cleaning cloths and other hand held cleaning mediums, and is ideal for car wash applications.
Moreover, the low access wringer requires minimal lifting of the mop. The bucket is easy and intuitive to operate.
Referring to any one of figures 19A to 28C, a bucket 10 for handling liquids according to a second embodiment of the present invention is shown.
As shown in Figures 22A and 22B, the bucket 10 comprises a collector reservoir 12' and a wringer receptacle 14'. The wringer receptacle 14' has a collector outlet 18' in fluid communication with the collector reservoir 12'.
The bucket also comprises a storage reservoir 16' having at least one discharge aperture 20'. The aperture 20' is better illustrated in Figures 20C
and 20D. The wringer receptacle 14' is positionable between a first position (shown in Figure 22A) wherein the wringer receptacle 14' blocks the discharge aperture 20' and a second position (shown in Figure 22B) wherein the wringer receptacle 14' allows fluid communication between the storage reservoir 16' and the wringer receptacle 14' through the discharge aperture 20'.
Preferably, as shown in Figures 20A to 20C, the storage reservoir 16' is removably attached to the bucket. If desired, the storage reservoir 16' can be lifted off and filled in a sink separately. The storage reservoir preferably has 8" total height. The reservoir also has handles 80' to snap fit on/off the reservoir on the bucket. Four legs 82' maintain the reservoir horizontal while filling. The storage reservoir also preferably comprises a self closing valve 26' as shown in Figure 20D. The storage reservoir preferably has a tank capacity of 8.9 L (2.35 Gallons).
Preferably, the wringer receptacle 14 comprises at least one fluid inlet aperture 22' and the at least one fluid inlet aperture 22' is in register with the at least one discharge aperture 20' when the wringer receptacle 14' is in the second position as shown in Figures 22A and 22B.
As also shown in Figures 22A and 22B, the wringer receptacle preferably comprises a biasing structure 28'. As mentioned previously, the storage reservoir may comprise a discharge aperture 20' and a spring valve 26' closing the discharge aperture 20'. Hence, the wringer receptacle 14' is positionable between a first position wherein the wringer receptacle biasing structure 28' allows fluid communication between the storage reservoir 16' and the wringer receptacle 14' through the discharge aperture 20' by actuating the spring valve 26', and a second position wherein the wringer receptacle biasing structure 28' releases the spring valve 26' and blocks fluid communication between the storage reservoir 16' and the wringer receptacle 14'.
Operational Use of the Bucket As mentioned previously, a user may start a mopping task by filling the storage reservoir 16' with a desired cleaning solution. Once this is accomplished, the operation can be broken down into two phases: mop rinsing and mop wringing.
Mop Rinsing The mop head 50' (rectangular sponge-type mop or round-type threaded mop) is positioned in the wringer receptacle 14' as shown in Figure 3. The 10 wringer receptacle may have an inscription "OPEN" where the mop head is to be placed. A downward force is then applied on the wringer receptacle 14' by applying a downward pushing force on the mop handle 52'.
As shown in Figures 22A and 22B, this will impose a 10 degree rotation of 15 the wringer receptacle. This moves the wringer receptacle biasing structure against the spring valve 26' which allows fluid communication between the storage reservoir 16' and the wringer receptacle. The mop is soaked and rinsed by 13 jets of flowing cleaning solution until the desired level of rinsing is achieved as shown in Figure 23. The average debit flow is 0.1 L/
sec (3.4 Fl. Oz I sec.). As the storage reservoir preferably has a capacity of flowing for 100 sec, there are 10 rinses possible at 10 sec per rinse for example. Any excess cleaning solution is automatically drained by gravity through drain openings 54' to the collector reservoir 12'. There is also a pooling effect of clean wash solution accumulating in the wringer receptacle 14'. Pool water is drained when wringer receptacle 14' is rotated back to the closed flow position.
Mop Wringing Wash solution flow into the wringer receptacle is interrupted by applying a downward force on the wringer receptacle 14', on the face where drain openings 54' are located as shown in Figure 24. This will impose a 10 degree rotation of the wringer receptacle in a direction opposite the mop rinsing procedure, moving the wringer receptacle biasing structure 28' away from the spring valve 26'. Mop wringing is also accomplished within the wringer receptacle by the same downward motion of the mop releasing excess solution into the collector reservoir 12' by gravity. The mop can now be lifted from the bucket and is ready for cleaning tasks.
Figures 25A and 25B illustrate operation of the valve in the closed flow position. The valve 26 comprises a plug 90' and a compressing spring 92'.
The compression spring 92' imposes a downward force on the plug 90' for sealing cleaning solution flow.
Figures 26A and 26B illustrate operation of the valve in the open flow position. Wringer receptacle 14' rotation imposes an upward force 94' acting against the valve 26' pushing up the plug 90', allowing cleaning solution to flow through the plug 90' into the wringer receptacle 14'.
Figures 27A to 27D illustrate the operation of the wringer receptacle rotation stops and locking features between closed flow position shown in Figures 27A and 27B and the open flow position shown in Figures 27C and 27D. As shown in the figures, the wringer receptacle lateral extensions 96' snap fit against a collector reservoir snap-fit feature 98'.
Figures 28A to 28C illustrate the storage reservoir 16' snap lock feature with the collector reservoir 12'. Handles 99' are provided to release the storage reservoir from the collector reservoir.
The above-mentioned second embodiment of the present invention is compatible with rectangular sponge type mops, traditional yarn mops, sponges, cleaning cloths and other hand held cleaning mediums, and is ideal for car wash applications.
Preferably, according to another preferred embodiment of the present invention, as shown in Figures 39A to 40B, the wringer receptacle 14 further comprises a pool drain 400 for draining liquids 402 from the wringer receptacle 14 independently of the collector outlet 18. This drain 400 prevents the pool water from coming in contact with the cleaning medium once the wringer is rotated to the closed flow position as illustrated in Figures 40A and 40B. The wringer receptacle 14 also comprises a concave-like floor 404 at one end allowing for liquids to pool up when it is rotated in the open flow position shown in Figure 40B. These pooled liquids 402 then exit the wringer receptacle 14 through the pool drain 400 when the receptacle is rotated back to the closed flow position shown in Figure 40A.
Figures 29A to 33B show a bucket 10 according to another preferred embodiment of the present invention. It is simple in design, has a low manufacturing cost and offers a high gross margin.
The three main parts are once again the collector reservoir 12", the wringer receptacle 14 and the storage reservoir 16 and can be assembled through a snap fit assembly. Additionally, the design provides for two standard sealing rings 40" that are installed in their mating wringer receptacle grooves.
All components may be manufactured from plastic materials through injection molding.
The wringer receptacle 14" is assembled onto the storage reservoir 16" by a simple snap fit feature 42" (shown in Figure 32A). In turn, the storage reservoir 16" is secured onto the bucket 10 by snapping onto a reinforced top edge of the collector reservoir 12".

This will impose a 10 degree rotation of the wringer receptacle in a direction opposite the mop rinsing procedure, moving the wringer receptacle biasing structure 28' away from the spring valve 26'. Mop wringing is also accomplished within the wringer receptacle by the same downward motion of the mop releasing excess solution into the collector reservoir 12' by gravity. The mop can now be lifted from the bucket and is ready for cleaning tasks.
Figures 25A and 25B illustrate operation of the valve in the closed flow position. The valve 26 comprises a plug 90' and a compressing spring 92'.
The compression spring 92' imposes a downward force on the plug 90' for sealing cleaning solution flow.
Figures 26A and 26B illustrate operation of the valve in the open flow position. Wringer receptacle 14' rotation imposes an upward force 94' acting against the valve 26' pushing up the plug 90', allowing cleaning solution to flow through the plug 90' into the wringer receptacle 14'.
Figures 27A to 27D illustrate the operation of the wringer receptacle rotation stops and locking features between closed flow position shown in Figures 27A and 27B and the open flow position shown in Figures 27C and 27D.

Figures 32A to 32F illustrate operation of the wringer receptacle between the closed flow position (Figures 32A to 32C) and the open flow position (Figures 32D to 32F). The mop head is first bottomed in the wringer receptacle 14" allowing the mop threads to position themselves between circumferentially arrayed cross-shaped protrusions 120". This allows the wringer receptacle 14" to be rotated by simple torsion of the mop handle.
The torsion applied to the mop handle is transferred to the wringer receptacle via an interlocking effect of the mop threads between the cross-shaped protrusions 120".

Operation of this bucket is similar to the other ones described above. First, the storage reservoir is filled with the desired solution. The mop is then placed on the OPEN side of the wringer receptacle, and a downward push of the mop handle rotates the wringer receptacle, this opening the wash solution flow. The mop is soaked and rinsed by 18 jets of flowing cleaning solution until the desired level of rinsing is achieved. Excess cleaning solution is automatically drained by gravity to the Drain Bucket. For wringing, the mop is placed on the drain side of the wringer receptacle, and a downward push of the mop handle rotates the wringer receptacle, thus closing the wash solution flow. The mop can then be wringed out in-situ.
Commercial Version of the Bucket Figures 37A to 38B illustrate another preferred embodiment of the present invention adapted to commercial-grade mop buckets and lever-actuated type mop wringers.
5 The commercial bucket 200 comprises two main assemblies, a collector reservoir 202 and a tank and wringer assembly 204. The collector reservoir 202 has two main functions: (1) capturing and storing used wash solution and (2) supporting the tank and wringer assembly 204 mounted on top of it.
The bucket is fitted with four directional wheels typically used in 10 commercial grade mop buckets.
As shown in Figures 37C and 37D, the tank and wringer assembly 204 can be divided into three sections: a wash solution tank 206, a wash solution flow control 208 and a wringer 210.
The wash solution tank 206 incorporates baffles to alleviate wash solution 15 inertia caused by displacement of the product. It is also fitted with a cover which can be pivotally mounted to the tank or be designed as a stand-alone lid.
It should be noted that most existing lever-actuated wringer designs can be used in the wringer section of the tank and wringer assembly 204.
further comprises a housing cover 100" projecting over a top area of the storage reservoir 16. The housing cover 100" comprises a pouring aperture 102" for allowing pouring of fluids therethrough into the storage reservoir 16".
Figures 34 to 36B show a bucket 10"' according to yet another preferred embodiment of the present invention. The design is compatible with rectangular sponge type mops and with threaded mops.
Figures 35A and 35B illustrate how the wringer receptacle 14"' rotates between the closed flow and open flow positions in this embodiment. In this case, a 15 wringer receptacle rotation is required to open and close cleaning solution flow.
A shown in Figures 36A and 36B, the main differences between this bucket and the previously shown ones include a recessed cavity 160"' for easy disposal of waste water through the collector reservoir spout. The storage reservoir also comprises rotation stops which also act as wringer receptacle locking features. A cylindrical snap-fit assembly feature 164"' is also provided.
Operation of this bucket is similar to the other ones described above. First, the storage reservoir is filled with the desired solution. The mop is then placed on the OPEN side of the wringer receptacle, and a downward push of the mop handle rotates the wringer receptacle, this opening the wash solution flow. The mop is soaked and rinsed by 18 jets of flowing cleaning solution until the desired level of rinsing is achieved. Excess cleaning solution is automatically drained by gravity to the Drain Bucket. For wringing, the mop is placed on the drain side of the wringer receptacle, and a downward push of the mop handle rotates the wringer receptacle, thus closing the wash solution flow. The mop can then be wringed out in-situ.
Commercial Version of the Bucket Figures 37A to 38B illustrate another preferred embodiment of the present invention adapted to commercial-grade mop buckets and lever-actuated type mop wringers.
5 The commercial bucket 200 comprises two main assemblies, a collector reservoir 202 and a tank and wringer assembly 204. The collector reservoir 202 has two main functions: (1) capturing and storing used wash solution and (2) supporting the tank and wringer assembly 204 mounted on top of it.
The bucket is fitted with four directional wheels typically used in 10 commercial grade mop buckets.
As shown in Figures 37C and 37D, the tank and wringer assembly 204 can be divided into three sections: a wash solution tank 206, a wash solution flow control 208 and a wringer 210.
The wash solution tank 206 incorporates baffles to alleviate wash solution 15 inertia caused by displacement of the product. It is also fitted with a cover which can be pivotally mounted to the tank or be designed as a stand-alone lid.
It should be noted that most existing lever-actuated wringer designs can be used in the wringer section of the tank and wringer assembly 204.
20 Preferably, as shown in Figures 38A and 38B, the bucket 10 comprises a flow control valve for controlling a flow rate through the at least one discharge aperture 20. This flow control mechanism 208 consists of a flow control lever acting as a valve. The horizontal section of the handle features multiple parallel holes through which the wash solution flows into the wringer receptacle. The holes are positioned in such a way that when the lever is in the closed position (vertical position), the wash solution flow is blocked by the handle's cylindrical surface. When the handle is rotated to the open flow position (as shown in Figures 38A and 38B), the holes 212 align with the tank and wringer assembly holes, thus allowing wash solution to flow into the wringer receptacle.
Preferably, according to another embodiment of the present invention, the bucket 10 may further comprise a storage drawer removably attached to the bucket 10 or added to the tank and wringer assembly. This compartment can be located below the tank section and be accessible from the front side. The storage feature of the product can take the shape of a drawer-type storage system or a simple opening giving access to a storage volume area.
The commercial bucket design has the benefit of requiring less effort from a user than with traditional commercial mop bucket and wringers while delivering superior cleaning results.
To operate the commercial bucket, a dry mop is first placed in the wringer receptacle. The flow control lever 208 is then rotated to open the wash solution flow into the wringer receptacle (as shown in Figure 38B). At this point, the mop is subjected to several jets of clean wash solution allowing for rinsing and soaking of the mop to a desired level. The excess wash solution is automatically drained into the collector reservoir. The flow of wash solution is interrupted by rotating the flow control lever 208 back to its original position. The mop, which is already located in the wringer, can easily be wrung out of excess wash solution and then used for cleaning.
Consequently, a product line based on the present invention may be developed. The bucket can be designed into multiple variations of shape and size. A floor mopping system option can be designed with bucket operation requiring a specially designed mop. Or a general purpose cleaning bucket may be designed for other cleaning media (sponge, cloth, etc.) Although the present invention has been explained hereinabove by way of preferred embodiments thereof, it should be pointed out that any modifications to these preferred embodiments within the scope of the appended claims is not deemed to alter or change the nature and scope of the present invention.
For example, the bucket geometry and wringer receptacle mechanism can be modified according to different designs and functional applications. The bucket components may be of circular or rectangular or any other shape. In all cases, the operating principles remain similar. Alternately, the storage reservoir can be closed off to form an integral storage tank. A housing cover is another alternative. The wringer valve mechanism can be alternately designed to operate by vertical translation rather than by rotation. In such a design configuration, a downward force on the mop stick opens the wash solution flow. The flow can then stop upon relieving the applied force. A compression spring may then be used in this configuration to load the wringer receptacle towards a closed position. The wringer receptacle mechanism can also be designed to allow for modulation of the wash solution flow rate (volume of solution per second) into the wringer receptacle. Numerous changes as the ones presented above may be attempted without departing from the spirit or scope of the invention.
Preferably, according to another embodiment of the present invention, the bucket 10 may further comprise a storage drawer removably attached to the bucket 10 or added to the tank and wringer assembly. This compartment can be located below the tank section and be accessible from the front side. The storage feature of the product can take the shape of a drawer-type storage system or a simple opening giving access to a storage volume area.
The commercial bucket design has the benefit of requiring less effort from a user than with traditional commercial mop bucket and wringers while delivering superior cleaning results.
To operate the commercial bucket, a dry mop is first placed in the wringer receptacle. The flow control lever 208 is then rotated to open the wash solution flow into the wringer receptacle (as shown in Figure 38B). At this point, the mop is subjected to several jets of clean wash solution allowing for rinsing and soaking of the mop to a desired level. The excess wash solution is automatically drained into the collector reservoir. The flow of wash solution is interrupted by rotating the flow control lever 208 back to its original position. The mop, which is already located in the wringer, can easily be wrung out of excess wash solution and then used for cleaning.
Consequently, a product line based on the present invention may be developed. The bucket can be designed into multiple variations of shape and size. A floor mopping system option can be designed with bucket operation requiring a specially designed mop. Or a general purpose cleaning bucket may be designed for other cleaning media (sponge, cloth, etc.) Although the present invention has been explained hereinabove by way of preferred embodiments thereof, it should be pointed out that any modifications to these preferred embodiments within the scope of the appended claims is not deemed to alter or change the nature and scope of the present invention.
