The present invention relates generally to a cleaning implement, and more specifically to a cleaning implement that may be used for household dusting.
The present invention provides a novel cleaning implement that enables the user to refresh the cleaning implement multiple times without the need to dispose of or replace the cleaning implement, and further provides a method relating to use of the cleaning implement.
The cleaning implement may include a support having a longitudinal axis, a plurality of cleaning sheets each having outward facing cleaning face and an inward facing attachment face, removably attached to the support, and a plurality of folded portions extending from the cleaning sheets and generally radially from the longitudinal axis of the support. The support may be any one of a flexible sheet, a pocket, a cleaning sheet, and an intermediate attachment sheet. A series of slits in the support and the cleaning sheets may be further included that form a plurality of loops in the folded portions of the support and the cleaning sheets. Alternatively, a series of slits may be included only in each cleaning sheet that forms a plurality of loops in the folded portions of the cleaning sheets. The plurality of cleaning sheets may be attached to the support with any one of an adhesive, a stitching, a fusion bonding, and a heat sealing bond. The support may also be attached to the cleaning implement with a pocket structure formed from a separate, nonwoven sheet.
The plurality of cleaning sheets are preferably layered in a stacked configuration such that only the outwardly facing cleaning face is exposed to ambient. The cleaning sheets are also preferably configured to allow detachment of a cleaning sheet, thus exposing to the ambient an additional cleaning sheet in the stacked configuration as a cleaning sheet is removed from the stack. A cleaning solution may be impregnated into the cleaning sheets to assist in dust removal and surface cleaning or disinfecting. In order to visually identify that the cleaning sheets are running out, a final cleaning sheet in contact with the support may include an indicia visually distinguishing it from the plurality of cleaning sheets. The indicia of the final cleaning sheet may also include a color distinct from a color of the plurality of cleaning sheets. To assist a user in cleaning with the cleaning implement, a holding space may be included in the support and configured to receive a handle.
In another embodiment, the cleaning implement may include a support sheet having a first surface, a second surface, and a longitudinal axis. The cleaning implement may include a plurality of detachable cleaning sheets, each having an outwardly facing cleaning surface and an inwardly facing attachment surface supported by the support sheet in a stacked configuration. A plurality of folded portions included with the support sheet and the cleaning sheet may extend generally radially from the longitudinal axis of the cleaning implement. A means to allow detachment of the inwardly facing surface of each cleaning sheet, allows a user to expose an additional cleaning sheet in the stacked configuration to the ambient. A final cleaning sheet may be included in the stack of cleaning sheets in contact with the support sheet, and one cleaning sheet may include indicia visually distinguishing it from the plurality of cleaning sheets, for alerting a user to refill the cleaning sheets. A cleaning solution may be impregnated into the cleaning sheets to assist in dusting, cleaning, and disinfecting.
A holding space may also be included in the support sheet and configured to receive a handle. To help increase contact area with the surface to be cleaned, a series of slits may be included in the support sheet and the cleaning sheets that form a plurality of loops in the folded portions of the support and the cleaning sheets. The cleaning sheet may be attached to each other with one of an adhesive, a stitching, a fusion bonding, and a heat sealing bond to attach the plurality of cleaning sheets to each other and the support sheet.
Also disclosed is a method of cleaning. The steps may include providing a cleaning implement that has a support sheet and a plurality of additional removable sheets, wherein the sheets have a plurality of folded portions that radially extend from a longitudinal axis of the cleaning implement. The steps may also include contacting an outermost sheet with a surface to be cleaned, using the outermost sheet to trap dust or other debris that is on the surface to be cleaned, and removing the outermost sheet from the cleaning implement to expose an unused sheet until just the support sheet remains. Lastly, the steps may include attaching the cleaning implement to a handle via the support sheet.

They are not limited to direct connection but include connection through other elements where such connection is recognized as being equivalent by those skilled in the art.
The present invention and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments described in detail in the following description.
A cleaning implement 10 is shown in
As shown in
The plurality of cleaning sheets 30 is attached to and supported by the support sheet 20. The plurality of cleaning sheets 30 may be attached directly to the support sheet 20, whereby the final cleaning sheet 34, that is most radially inwardly with respect to the longitudinal axis 11, is attached to the support sheet 20. The outer-most cleaning sheet 35 is the sheet available for contacting a surface to be cleaned. The cleaning sheet 30 may be attached via any suitable method such as by adhesive, stitching, fusion bonding, or heat sealing. The cleaning sheets 30include a cleaning face 31 and an attachment face 33. The cleaning face 31 of each cleaning sheet 30 is the surface intended to contact a surface to be cleaned. The attachment face 33, shown in
The cleaning sheets 30 are configured so that the outermost cleaning sheet 30 is removable from the plurality of cleaning sheets 30, as shown in
The ease with which the cleaning implement 10 may be refreshed is desirable to the user. In other words, the user may refresh the cleaning implement 10 numerous times without the need to completely replace the cleaning implement 10 or the need to clean the cleaning implement 10 itself, e.g., in the washing machine or the sink, or shaking the cleaning implement 10 outside. Thus, the removable cleaning sheets 30 of the cleaning implement 10 enable a user to clean for a greater period of time with minimal interruption, the minimal interruption being the removal of the outermost cleaning sheet 30 when it becomes too soiled and/or experiences reduced cleaning efficacy. Put another way, comparing a conventional cleaning implement to an embodiment of the cleaning implement 10 having ten cleaning sheets 30, a user would have to replace the conventional cleaning implement ten times once the cleaning implement became soiled and/or experienced reduced cleaning efficacy, which is time consuming and costly, as opposed to simply removing a cleaning sheet 30 from the cleaning implement 10, which is far more efficient and less time consuming.
The cleaning sheets 30 may be secured together using any suitable means that provides for the easy removal of the cleaning sheets 30 from the cleaning implement 10 while at the same time preventing inadvertent removal of the cleaning sheets 30 under the typical forces experienced during household dusting. For example, the cleaning sheets 30 may be attached to one another via stitching, adhesive, fusion bonding or heat sealing. In one embodiment, the sheets are attached to one another via a plurality of attachment members 24, described in further detail below. See
The cleaning sheets 30 are made from a material that is flexible and that has properties enabling the cleaning sheet 30 to collect and retain dust and other debris. In one embodiment, the cleaning sheets 30 are nonwoven sheets, for example a 35-55 gsm spunlace nonwoven material. Such material may be 100% polyester, or it may be substantially polyester with microfiber of nylon. In another embodiment, the innermost cleaning sheet 30 could be made of a thicker material, such as 90-110 gsm spunlace nonwoven, to provide additional support and structure to the cleaning implement 10 and to the plurality of cleaning sheets 30. Moreover, the cleaning sheets 30 may be impregnated with a cleaning solution to further facilitate dust removal. Additionally, the cleaning sheets 30 may include an adhesive to further improve dust removal and retention. In one embodiment, the adhesive could be applied to valleys 42. Further, the cleaning sheets 30 and support sheet 20 may be different colors. Thus, when a user has reached the last cleaning sheet 30, the support sheet 20 may serve as an indicator of the last cleaning sheet 30. Alternatively, the final cleaning sheet 30 could be colored differently than the other cleaning sheets 30 or contain some other indicia notifying the user that it is the last cleaning sheet 30.
The support sheet 20 and cleaning sheets 30 are configured about the longitudinal axis 11 of the cleaning implement 10 so as to form a plurality of folded portions 40. As shown in
Moreover, the folded portions 40 create a three-dimensional cleaning surface area as opposed to the generally two dimensional cleaning surface areas of conventional fiber bundle dusters. The three-dimensional surface area of the cleaning implement 10 can easily and quickly be refreshed by removing the outermost cleaning sheet 30, whereas a conventional fiber bundle duster cannot be refreshed—it must be replaced or cleaned in some other way. Moreover, the height of the folded portions 40 corresponds to the resiliency, or “floppiness,” of the cleaning implement 10. The greater the height of the folded portions 40, the floppier the cleaning implement 10 will be. Conversely, the shorter the height of the folded portions 40, the stiffer the cleaning implement 10 will be.
The support sheet 20 may be made of a flexible, resilient material that will substantially maintain its shape after exposure to typical forces of normal household dusting. In one embodiment, the support sheet 20 is made from 15-25 gsm polypropylene spunbond. Thus, the folded portions 40 of the support sheet 20 will similarly be flexible and resilient during the dusting process while maintaining its shape. The overall shape of the cleaning implement 10 will be substantially unchanged after dusting, which extends the longevity and effectiveness of the cleaning implement. The resilient nature of the cleaning implement 10 is a desirable quality to consumers as consumers do not like when a cleaning implement quickly loses its shape.
The cleaning sheets 30, when attached to the support sheet 20, substantially conform to the shape of the support sheet 20. Prior to assembly into the cleaning implement 10, the support sheet 20 may be rectangular in shape. The plurality of cleaning sheets 30 may also be rectangular in shape and attached to the support sheet 20 when the cleaning implement 10 is in an unassembled form. When assembled into the cleaning implement 10, the support sheet 20 is configured about the longitudinal axis 11 of the cleaning implement 10 to form the folded portions 40, a configuration that is similarly adopted by the cleaning sheets 30. The parts of the support sheet 20 may be secured, for example to other parts of the support sheet 20, in order to maintain the folded portions 40. Alternatively, the support sheet 20 may be formed or processed to maintain the folded portions 40, in other words, so that the final shape of the support sheet 20 that forms the cleaning implement 10 is the natural state of the cleaning sheet 20.
In one embodiment, a plurality of attachment members 24 is used to maintain the shape of the cleaning implement 10 and also to secure the cleaning sheets 30 to one another. The attachment members 24 may be stitching, a heat seal, a fusion bond, a pin, or any other structure capable of holding the support sheet 20 and cleaning sheets 30 together so as to maintain the shape of the cleaning implement 10. Alternatively, the attachment members 24 that hold the cleaning sheets 30 together may be separate from attachment members 24 that secure the cleaning sheets 30 to the support sheet 20. There may be further attachment members 24 that hold various portions of the support sheet 20 together. In sum, there are three functions performed by attachment members 24: (1) securing the cleaning sheets 30 to one another in a way that individual cleaning sheets 30 are removable from the stack of cleaning sheets 30, (2) securing the plurality of cleaning sheets 30 to the support sheet 20 (3), and securing portions of the support sheet 20 to one another to form the overall shape of the cleaning implement 10. The attachment members 24 may serve one, all, or any combination of these functions.
As shown in
In the embodiment shown, for example in
As discussed above, the support sheet 20 provides the shape and structure of the cleaning implement 10, which includes the plurality of folded portions 40. There may be any number of folded portions 40, but preferably a number of folded portions 40 is such that facilitates effective dusting and ease of use. In the embodiment shown, the cleaning implement 10 has eight folded portions 40, which has been proven to facilitate effective dusting while at the same time enabling easy removal of the cleaning sheets 30.
As shown in
Accordingly, each folded portion 40 is separated into a series of adjacent loops 53 that are arranged along the folded portion 40. As with the folded portions 40, the loops 53 extend radially outwardly from the longitudinal axis 11, (see
Put another way, when the support sheet 20 and cleaning sheets 30 are in a rectangular form, the slits 50 are arranged into slit groups 52, with each slit group 52 organized along a line that is substantially parallel to the longitudinal axis 11 of the cleaning implement 10. See
The pocket structure 54, shown in
The configuration of the cleaning implement 10 to include folded portions 40 and valleys 42 increases the cleaning surface area of the cleaning implement 10. The cleaning surface area is defined as the surface area of the cleaning implement 10 that is used to clean. Here, the cleaning surface area is the area of one of the cleaning sheets 30. Moreover, taking into consideration the multiple removable cleaning sheets 30, the cleaning surface area of the cleaning implement 10 is multiplied by a factor of however many cleaning sheets 30 there are. Thus, the cleaning implement 10 has a far greater cumulative cleaning surface area than conventional dusters that must be replaced once they become soiled and/or lose cleaning efficacy, as opposed to the cleaning implement 10 that is simply and quickly refreshed by removing the outermost cleaning sheet 30.
The present invention further includes a method of cleaning using a cleaning implement 10 as described above. The method includes providing a cleaning implement 10 as described above, and contacting the cleaning implement 10 with a surface to be cleaned. Then, the cleaning implement 10 is used to trap dust or other debris that is on the surface to be cleaned. The outermost cleaning sheet 30 is then removed from the cleaning implement 10 to expose the next, unused cleaning sheet 30. The cleaning process may then be repeated until there are no more unused cleaning sheets 30 left.
Although the best mode contemplated by the inventors of carrying out the present invention is disclosed above, practice of the present invention is not limited thereto. It will be manifest that various additions, modifications and rearrangements of the features of the present invention may be made without deviating from the spirit and scope of the underlying inventive concept. There are virtually innumerable uses for the present invention, all of which need not be detailed here. All the disclosed embodiments can be practiced without undue experimentation.
Moreover, the individual components need not be formed in the disclosed shapes, or assembled in the disclosed configuration, but could be provided in virtually any shape, and assembled in virtually any configuration. Furthermore, all the disclosed features of each disclosed embodiment can be combined with, or substituted for, the disclosed features of every other disclosed embodiment except where such features are mutually exclusive.
