STATEMENT REGARDING FEDERAL SPONSORSHIPThe present invention was not made or developed with Federal sponsorship.
BACKGROUND OF THE INVENTIONThis invention relates to a disposable sheath with hygienic cleaning pad elements to be used in conjunction with specially designed floor mop heads.
BACKGROUND-DESCRIPTION OF PRIOR ARTNumerous tools have been developed to clean floors and other surfaces of dirt, debris and other contaminants. Traditional mops with strands of yarn or rope can be effective in cleaning a floor but must be wetted by water in a container and then cleaned and rinsed afterwards by hand or by a squeeze mechanism typically located within a mop bucket.
Cleaning floors in hospitals presents even more of a challenge. Not only do re-usable mops need to be laundered between use in some areas of a hospital, such an in operating rooms, they present a health hazard to the janitorial staff when being removed from the mop head and transported to the laundry. Mops are not even supposed to be returned to the bucket following cleaning of operating room floors, such is the need to avoid cross-contamination of different rooms.
The need to improve the sanitary handling and ease of use of mops has led to such innovations as disposable cleaning elements that are simply discarded after use. Cleaning elements comprised of disposable pad elements or wipes eliminate the need to wash and rinse the mop itself. For example, U.S. Pat. No. 6,651,290 B2 describes an implement with a cleaning head to receive and retain a disposable pad element. An attachment mechanism is designed to hold the pad element securely in place as it is wrapped around the mop head. Likewise, U.S. Pat. No. 6,298,517 B1 describes a disposable series of pad elements that are attached to a mop head. These and other similar mop configurations benefit from having disposable pad elements that negate the need to clean the mop after use. However, many of these mops suffer from several serious drawbacks:
- (a) One of the most serious drawbacks is the need for the user to touch the pad elements during installation and removal. Consumers who abandoned traditional wet mops because they didn't want to clean the mop head of dirt and grime must still get their hand wet while attaching or detaching a disposable pad element. The need to touch the disposable pad element precludes the use of stronger cleaning chemicals than would otherwise be the case. In some environments, detaching soiled pad elements from a mop head represents a health hazard. For example, in hospitals there are large numbers of microorganisms that cause infections. It would not be safe for a maintenance worker to touch a soiled pad element directly with a bare hand after mopping a hospital room floor. With prior art disposable pad elements, a protective glove would have to be worn before detaching the soiled pad element. Once removed, prior art disposable pad elements can still represent a source of contamination, as the pad is not necessarily isolated.
- (b) Chemicals to enhance the cleaning, dusting or disinfecting action of a floor mop or a dust mop are common. Disposable pad elements moistened with such chemicals are desirable but difficult to handle. A consumer may not want to touch a pad element moistened with a strong cleaning chemical because of potential irritation to the skin. This represents a paradox for the buyer of disposable cleaning pad elements: the more effective the chemically-treated pad elements are at cleaning dirty floors, the less willing the user is to handle the pad elements while directly attaching them and detaching them from the mop head. This leads manufacturers to use milder cleaning solutions than they otherwise would choose if the user did not have to touch the disposable pad elements. This is a particularly important issue for use of disposable pad elements in hospitals or other high-risk environments. Extra strong cleaning chemicals can help prevent the spread of nosocomial infections by reducing the general bacterial load on floor surfaces. However, with prior art devices, there has been a limitation on strength of such chemicals used to soak disposable pad elements unless users also wore gloves to protect themselves from the harsh effects of such chemicals during installation and removal of the pad elements from the mop head.
- (c) Pre-moistened disposable pad elements have a propensity to dry out before use. While pad elements can be stored in a sealable, waterproof container, such pad elements can and do dry out if stored for long periods of time between use. A wet mop with a disposable pad element is of little benefit to the consumer once the pre-moistened pad elements have dried out. Even if the pad elements don't dry out, the container in which the pad elements are stored must be placed in a flat position on the floor, on a shelf or on a counter top, thus wasting valuable storage space.
- (d) Current disposable pad elements have to resist tearing across their entire surface when placed on a mop head because they are most commonly attached to the mop head only at the four corners. This tear resistance across the entire mop head surface can lead to higher manufacturing costs compared to pad elements that can be attached to the mop head at multiple sites on the face of the mop head.
- (e) Current disposable pad elements can be difficult to attach to the mop head. The element must be positioned centrally on the mop head while each of the four corners is tucked around to the opposite face and inserted into the attachment mechanism. The disposable pad element can dislodge during the installation procedure, making it difficult to line up the corners of the pad with the attachment mechanisms.
- (f) Current disposable pad elements are stored separate from the mop head, sometimes getting lost in the clutter of objects stored in the cleaning closet or under the sink.
This invention is based on the novel and surprising concept of using a disposable sheath with a first surface and a second surface to attach one or more pad elements to a specially designed mop head. In the first position, one or more pad elements attached to the first surface face inward, either for storage prior to initial use or for touch-free disposal following use. In the second position, one or more pads attached to the first surface face outward and can be used to apply a cleaning, dusting or disinfecting solution to a floor surface. The disposable sheath is placed into each of the two positions by means of moving the sheath over a specially designed mop head that inverts the sheath as it moves from the first position, in which it is initially stored, to the second position where it is used on a floor surface and then back to the first position where it can be disposed of in a sanitary fashion.
In one embodiment the mop head takes the shape of a partially flattened cylinder with an interior surface and an exterior surface. A disposable sheath in the first position, with one or more pad elements facing inward, is placed inside the hollow mop head. The one or more pad elements attached to the first surface of sheath in the first position can be wetted with a cleaning, dusting or disinfecting solution and sealed within a first chamber to prevent evaporation of the solution during storage. Upon opening of the first chamber, one end of disposable sheath is pulled out and over the edge of the mop head, inverting the sheath in the process. Following complete inversion of the sheath as it is drawn down the length of the mop head, the one or more moistened pad elements attached to the first surface are now located in the second position with the pad elements facing outward. When the disposable sheath is in the second position, the second surface of the disposable sheath faces inward and contacts the mop head on its exterior surface.
In the preferred embodiment, a tether element is attached to one end of the disposable sheath. After the one or more moistened pad elements in the second position have been used to clean, dust or disinfect a floor surface, the tether element attached to the interior surface of the mop head can be pulled out from the interior of the mop head, returning the pad elements to the first position facing inward where they can then be discarded. Returning the soiled pad elements to the first position without the user having to touch the contaminated surface leads to easy disposal of the sheath and is one of the many novel aspects of this invention.
In the preferred embodiment the mop head and attachment rod are configured to facilitate the easy placement of the disposable sheath on the mop head. The mop head can be placed in a mostly vertical position by resting the entire mop head assembly on a loading plate attached to a rod, with the rod angled to place the mop head directly over the loading plate. The stand provided by means of the loading plate makes both hands of the user available to invert the sheath over the mop head.
In another embodiment, multiple disposable sheaths are placed in a storage cartridge that can be easily loaded into the mop head. In yet another embodiment, multiple disposable sheaths can be stored in a disposable mop head that can be discarded after all the individual sheaths have been used.
Objects and AdvantagesAccordingly, several objects and advantages of the present invention are:
- (a) to provide a disposable sheath with at least one pad element moistened with cleaning, dusting or disinfecting solution sealed in chamber one. The placement and inversion of the disposable sheath upon the mop head can be achieved without the user ever directly contacting the moistened pad elements;

DETAILED DESCRIPTION OF THE INVENTIONA mop handle is attached to the mop head at connector 28. Connector 28 is attached to rod 24 at pivot joint 26. Rod 24 is bent at several locations and is attached to the inside of mop head 20 through hole 32 in molded section 30. Rod 24 is similar in shape to the rod portion of a paint roller except that connector 28 is attached to rod 24 at hinge 26. Rod 24 is secured to mop head 20 along the length of molded section 30, providing a pivot point between the mop head 20 and rod 24. This allows mop head 20 to remain flat on the floor or other surface as the mop handle attached at connector 28 is raised or lowered and so that upper surface 34 can be flipped to exchange position with lower surface 35 of mop head 20. This provides the means for both exterior surfaces of mop head 20 to contact the floor once disposable sheath 1 is attached and the mopping operation is commenced. Rod 24 is placed in hole or cavity 32 of molded section 30 at distal end 40 of mop head 20.
Loading plate 38 is attached to rod 24 to provide a means upon which mop head 20 can be placed in a vertical position to easily effect a change of disposable sheath 1 from the first position with pad elements facing inward to the second position with pad elements facing outward.
The dimensions of mop head 20 depend on the intended use. For typical consumer use, the upper surface 34 of mop head 20 would preferably be ten inches in length and five inches in width. The distance between the upper exterior surface 34 and the lower exterior surface 35 could be as little as a half inch or as much as several inches. The preferred depth of the interior chamber of the mop head is such as to allow storage of the desired number of disposable sheaths 1 in the interior space. This is preferably ten or more. Mop head 20 designed for commercial applications may have larger dimensions to facilitate coverage of larger floor surface areas in less time. The wall thickness of mop head 20 should be adequate to provide structural stability during use and to facilitate the process of inverting disposable sheath 1 from the first position to the second position for cleaning and back to the first position for disposal. The wall thickness is preferably 1/4 inch.
Upon completion of the cleaning, dusting or disinfecting operation, after both moistened pad elements 2 and 14 are dirtied, tether 12 is grasped from within distal end 40 of mop head 20 and pulled out and away from mop head 20. This reverses the earlier process of placing disposable sheath 1 on the exterior surface of mop head 20. It moves the disposable sheath from the second position where pads 2 and 14 face outward back to the first position where the pads 2 and 14 face inward. Tether 12 is then used to pull the disposable sheath in the first position from inside mop head 20 for disposal. The simple operations of installing and removing disposable sheath 1 without ever having to touch a wet surface with ones hands accomplishes two of the main objectives of the invention. This makes it possible to moisten pad elements 2 and 14 with stronger chemical cleaners than would otherwise be the case if the user were required to touch the wet surface of pad elements 2 and 14 with his or her fingers. In addition, the disposal operation is not only safer for the consumer it is more hygienic because the user never has to touch the soiled pad elements 2 and 14. They are isolated in the first position within the disposable sheath that has been turned outside in.
Combining two chemicals, such as an activator and a base solution, and applying it to the disposable mop head just before use can lead to enhanced microbicidal activity. Another embodiment of this invention would be to apply the base chemical to the pad elements at time of manufacture and store the activator in the tether. Just before use, the activator could be transferred, all under a closed system, from the tether through a breakable seal to compartment one containing the pad elements where it could activate the base chemical for maximum disinfecting power. This extreme design feature would likely only be required in hospital applications where germicidal activity in cleaning floors is of the utmost importance.
The foregoing description of the preferred embodiments of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Modifications or variations are possible and contemplated in light of the above teachings by those skilled in the art, and the embodiments discussed were chosen and described in order to best illustrate the principles of the invention and its practical application. It is intended that the scope of the invention be defined by the claims appended hereto.
