The present disclosure relates generally to cleaning products, and more particularly to a disposable device for manual cleaning toilet bowls and urinals.
Restrooms and bathrooms must be cleaned and sanitized on a regular basis to prevent the spread of germs and disease. Health and sanitation concerns require that toilets and urinals be cleaned frequently. This cleaning is typically carried out using a brush attached to an elongated handle. However, once a cleaning device is used, the cleaning device itself may then transfer bacteria and other contaminates to subsequent toilets as it is reused. Thus, the cleaning process itself may lead to the spread of contamination. This issue may be particularly problematic in public buildings and institutional settings such as hospitals, schools, airports and the like.
In recognition of this problem, a number of devices have been developed incorporating reusable handles coupled with removable cleaning elements. While such devices provide some benefit, the reusable handles may still transfer contaminates between toilets. Several systems have been proposed incorporating handles formed from cardboard, paper or similar water-degradable materials such that the entire device is disposable after use. By way of example only, one such system is described in US patent publication 20060174914 to Murphy (incorporated by reference). Another such system is disclosed in US patent publication 20040019996 to Singer (incorporated by reference). While such fully disposable systems may be beneficial if used properly, they are still susceptible to misuse by cleaning personnel who reuse the same device on several toilets before disposal in a well-intentioned effort to reduce waste. Moreover, as best understood, the cleaning surfaces of the prior fully disposable devices are not well configured to promote cleaning by application of pressure during use.
Considering the various noted problems associated with current systems, an alternative disposable cleaning tool that aids in preventing undesirable multiple uses while also promoting cleaning efficiency would represent a useful advancement over the current art.
The present disclosure offers advantages and alternatives over the prior art by providing a manual toilet cleaning tool incorporating an elongated handle of parallel wound cardboard or similar material permanently affixed to a cleaning pad of polylactic acid (PLA) nonwoven or other biodegradable polymer of sufficient abrasive character to provide desired cleaning. The handle may be hollow and be of a generally hydrophilic character which loses its structural integrity when saturated with liquid. Slits or other liquid openings are provided in the handle in a zone adjacent to the cleaning pad to purposely promote the introduction of water into the handle interior during a cleaning procedure thereby speeding handle saturation and degradation. The handle may be cut and flared at the end to form a plurality of outwardly projecting radial prongs supporting the cleaning pad at its interior.
Before the exemplary embodiments of the invention are explained in detail, it is to be understood that the invention is in no way limited in its application or construction to the details and the arrangements of the components set forth in the following description or illustrated in the drawings. Rather, the invention is capable of other embodiments and being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for purposes of description only and should not be regarded as limiting. The use herein of terms such as “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
An exemplary embodiment consistent with the present disclosure will now be described in reference to the drawings wherein like elements are designated by like reference numerals in the various views. Referring now to the drawings, a manual cleaning tool 10 consistent with the present disclosure is illustrated. As shown, the manual cleaning tool 10 includes a handle 12 of cardboard or a like material permanently affixed to a cleaning pad 14 of PLA or other biodegradable fiber by adhesive, heat bonding or other suitable techniques. By way of example only, and not limitation, the handle 12 may be a parallel wound cylindrical cardboard tube which is hollow along its entire length. However, other materials and constructions may be used if desired.
As best seen in
As noted previously, the introduction of fluid to the handle interior speeds the handle degradation thereby reducing the operative life of the cleaning tool. Such a reduction in operative life may aid in preventing reuse. The fluid contact creates a physical and/or chemical reaction that weakens the handle walls. In this regard, it is contemplated that the handle may include features such as sodium bicarbonate, sodium sulfate or the like that react chemically with the fluid to accelerate the degradation of the handle walls. In addition, it is desirable that the fluid openings 16 be large enough to facilitate rapid drainage of fluid out of the handle core following use to avoid substantial dripping when the handle fails. That is, substantial amounts of fluid should not be trapped in the handle core.
As best seen in
As will be appreciated, when the cleaning pad is pressed against a surface to be cleaned, the radial prongs 20 will be urged downwardly thereby spreading outwardly. This outward spreading will cause the cleaning pad to be tensioned as it moves from its unstressed concave orientation to a more flattened condition. The tensioned pad surface will thereby provide more efficient scrubbing action during cleaning. Because the radial prongs are formed from the handle body, no additional material is required. Moreover, as the prongs become wetted, they will lose resilience thereby further prompting a user to discard the used device.
Preferred embodiments of this disclosure are described herein, including the best mode known to the inventors for carrying out the disclosure. Variations of those preferred embodiments may become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventors expect skilled artisans to employ such variations as appropriate, and the inventors intend for the disclosure to be practiced otherwise than as specifically described herein. Accordingly, this disclosure includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the disclosure unless otherwise indicated herein or otherwise clearly contradicted by context.
This nonprovisional application claims the benefit of, and priority from, U.S. provisional application 62/981,240 filed Feb. 25, 2020. The contents of such provisional application and all other documents referenced herein are hereby incorporated by reference in their entirety as if fully set forth herein.
