The present invention relates to a spot cleaner, and more particularly to a spot cleaner that uses wet and dry materials to clean spots.
There are a variety of products and processes that are used to clean carpet and/or upholstery. Some of these products are specifically designed to clean spots on localized areas of carpeting or upholstery.
One drawback with using some spot cleaning products is that there is a risk of damaging the carpet or upholstery where the spot is located. As an example, when brisk brushing is used in combination with a cleaner to clean a spot, the resulting shear forces that are generated on the carpet or upholstery often harm the underlying carpet or upholstery.
Another drawback with some spot cleaning products is that the products may leave unsightly residue on the carpet or upholstery. In addition, any dyes that are part the spot-cleaned area may become discolored or partly removed.
There is a need for a spot cleaner that utilizes a cleaner in combination with mild mechanical agitation to loosen and remove the spot from a localized area on carpet or upholstery. The spot cleaner should be able to clean spots from carpet or upholstery without abrading or otherwise damaging the carpet or upholstery.
The present invention relates to spot cleaner that may be used to remove a spot from a localized area of a substrate (e.g., carpeting or upholstery). The spot cleaner utilizes a cleaner that is effective at dissolving and/or suspending spots in combination with mild mechanical agitation to clean spots without abrading or damaging the underlying substrate.
In one example embodiment, the spot cleaner includes a first absorbent pad and a second absorbent pad. The first absorbent pad includes a cleaner. The spot cleaner further includes a moisture proof barrier that is between the first absorbent pad and the second absorbent pad. The moisture proof barrier encloses the first absorbent pad to keep the cleaner inside the moisture proof barrier. In some embodiments, the moisture proof barrier may serve as packaging for the first absorbent pad and the cleaner before the spot cleaner is used to clean a spot.
In another example embodiment, the spot cleaner includes a first absorbent pad and a second absorbent pad. The first absorbent pad includes a cleaner. The spot cleaner further includes a moisture proof barrier that has a first layer attached to the first absorbent pad and a second layer attached to the second absorbent pad. The first and second layers are between the first absorbent pad and the second absorbent pad. In addition, the moisture proof barrier encloses the first absorbent pad to keep the cleaner inside the moisture proof barrier. In some embodiments, the first and second layers of the moisture proof barrier may be separable to allow a hand to be inserted between the first and second layers so that the hand is able to manipulate the spot cleaner without any portion of the spot or cleaner engaging the hand.
The present invention also relates to a method of cleaning a spot from a localized area. The method includes positioning a spot cleaner near the localized area. The spot cleaner includes a first absorbent pad and a second absorbent pad. The first absorbent pad includes a cleaner. The spot cleaner further includes a second absorbent pad and a moisture proof barrier that is between the first absorbent pad and the second absorbent pad. The moisture proof barrier encloses the first absorbent pad.
The method further includes manipulating the moisture proof barrier to expose the first absorbent pad and holding the first absorbent pad against the localized area such that the cleaner disengages the spot from the localized area. The method further includes absorbing at least some of the cleaner and at least some of the disengaged spot from the localized area using the second absorbent pad.
The method may further include covering the first absorbent pad with the moisture proof barrier after the cleaner disengages the spot from the localized area. In some embodiments, the moisture proof barrier includes a first layer that is attached to the first absorbent pad and a second layer that is attached to the second absorbent pad such that the method further includes inserting a hand between the first layer and the second layer and then pressing the first or second absorbent pad against the spot using the hand.
The purposes and features of the present invention will be set forth in the description that follows. Additional features of the invention will be realized and attained by the product and processes particularly pointed out in the written description and claims hereof, as well as from the appended drawings.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the invention claimed. The accompanying drawings, which are incorporated in and constitute part of this specification, are included to illustrate and provide a further understanding of the invention.
The present invention will be more fully understood, and further features will become apparent, when reference is made to the following detailed description and the accompanying drawings. The drawings are merely representative and are not intended to limit the scope of the claims. Like parts depicted in the drawings are referred to by the same reference numerals.
In the following detailed description, reference is made to the accompanying drawings, which show specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that other embodiments may be utilized and structural changes made, such that the following detailed description is not to be taken in a limiting sense.
The present invention relates to a spot cleaner that may be used to aid individuals in cleaning spots from a substrate (e.g., carpet or upholstery). The spot cleaner is applied to a substrate so that a cleaner engages an area on the substrate where the spot located. The cleaner may be distributed over the area where the spot is located by mildly manipulating the spot cleaner over the area.
Combining the cleaner with mild mechanical agitation serves to physically dislodge and/or dissolve any spots. The cleaner and the particulate form a solution that is absorbed (e.g., by capillary action) into a pad and transported away from the substrate.
In the illustrated example embodiment, the moisture proof barrier 18 includes a first section 19, a second section 20 and a fold 21 that separates the first section 19 from the second section 20. The first section 19 of the moisture proof barrier 18 is between the first and second absorbent pads 12, 16.
It should be noted that moisture proof barrier 18 may be a variety of materials. As an example, moisture proof barrier 18 may be a polymeric film.
In other embodiments, the second section 20 may be removable from the spot cleaner 10 to expose the first absorbent pad 12. As an example, the moisture proof barrier 18 may include a weakened (e.g., perforated) section (not shown) such that opening the moisture proof barrier 18 may include tearing the weakened section of the moisture proof barrier 18 to remove a portion (e.g., second section 20) of the moisture proof barrier 18.
Cleaner 14 may be any material that is known to clean spots and may be in any form (e.g., liquid, solid, powder, granules). In addition, cleaner 14 may be a combination of materials. As an example, cleaner 14 may be a liquid solution that includes surfactants which provide detersive cleaning benefits and organic solvents which serve to loosen the bonds between particles.
In some embodiments, cleaner 14 may be water-based as opposed to solvent-based in order to avoid flammability and odor problems. A water-based cleaner 14 may also lessen the likelihood of the cleaner 14 damaging the substrate (e.g., carpet or upholstery) where the spot is located.
In addition, the cleaner 14 may be fairly dilute so that it does not leave a ring on the substrate. As an example, the cleaner 14 may be a 2% solution of a detergent/surfactant in water such that the cleaner 14 is gentle on carpets and/or fabrics.
In some embodiments, the cleaner 14 may be a non rinse composition that leaves no residue behind. The cleaner 14 may also include a fragrance and/or odor reducing agent.
The first and second absorbent pads 12, 16 may be made of the same material or different materials. In some embodiments, the first and second absorbent pads 12, 16 have surfaces with high abrasion resistance such that they do not leave lint on a substrate as a user rubs the pads 12, 16 against the substrate. In addition, the first and second absorbent pads 12, 16 may be textured to facilitate cleaning certain types of spots.
The first absorbent pad 12 may be a lofty material with large capillary structure so that first absorbent pad 12 readily releases the cleaner 14. In addition, the second absorbent pad 16 may have a small capillary structure so that the second absorbent pad 16 readily absorbs the cleaner 14 and any released spot materials from the carpet or upholstery. The second absorbent pad 16 may have enough absorbent capacity to hold (i) the amount of cleaner 14 that gets released during the cleaning operation; and (ii) any material that was associated with the original spot.
An example material that may be used for the first absorbent pad 12 is a 50% polymer-50% fiber coform material. An example material that may be used for the second absorbent pad 16 is a combined wettable spunbond/meltblown material with the spunbond material facing outward so that the spunbound material engages the spot first.
In some embodiments, the second absorbent pad 16 may be a nonwoven material with sufficient capacity to absorb an amount of urine that a large pet (e.g., a dog) might void. The second absorbent pad 16 may also be used to pick up solid or semi solid objects (e.g., fur balls and/or feces). In addition, the second absorbent may be a super absorbent material (e.g., a commercially available acrylic acid-based hydrogel material).
It should be noted that the spot cleaner 10 may be manufactured in multiple sizes. The size and type of spot cleaner that is chosen to clean a spot will depend in part on the size and type of spot that is to be cleaned and the type of substrate where the spot is located.
In the illustrated example embodiment, the moisture proof barrier 38 includes a first section 39, a second section 40 and a fold 41 that separates the first section 39 from the second section 40. The first section 39 of the moisture proof barrier 38 is between the first and second absorbent pads 32, 36.
As shown in
In some embodiments, the first and second layers 42, 43 may be sized and joined together such that a user is able to turn the moisture proof barrier 38 inside out. Turning the moisture proof barrier 38 inside out to store the cleaner 34 and the spot inside the moisture proof barrier facilitates disposing of the spot cleaner 30 under hygienic conditions.
There are some embodiments of spot cleaner 30 where only the first layer 42 encloses the first absorbent pad 32 (
It should be noted that any of the spot cleaners described herein may further include a third absorbent pad. As an example,
The third absorbent pad 39 may be used to initially engage the spot and absorb at least some portions of the spot. As an example, the third absorbent pad 39 may make the spot cleaner 30 more effective by removing large amounts of the spot (e.g., pet feces) before the first absorbent pad 32 and cleaner 34 are applied to the spot. In some embodiments, the third absorbent pad 39 may have the ability to be removed (e.g., torn away) from the spot cleaner 30 to allow the soiled third absorbent pad 39 to be discarded.
A method of cleaning a spot 100 from a localized area 101 will now be described with reference to 14A-14D. The method includes positioning a spot cleaner 10 near the localized area 100. The spot cleaner 10 includes a first absorbent pad 12 and a second absorbent pad 16. The first absorbent pad 12 includes a cleaner 14. The spot cleaner 10 further includes a moisture proof barrier 18 that is between the first and second absorbent pads 12, 16. The moisture proof barrier 18 encloses the first absorbent pad 12 to keep the cleaner 14 within the moisture proof barrier 18.
The method further includes manipulating the moisture proof barrier 18 to expose the first absorbent pad 12 (
In some embodiments, the moisture proof barrier 18 may be a layer such that manipulating the moisture proof barrier 18 includes peeling a portion of the layer back from the rest of the moisture proof barrier 18 in order to expose the first absorbent pad 12 and cleaner 14 (
In some embodiments, the spot cleaner 10 may include a third absorbent pad (not shown in
Another method of cleaning a spot 100 from a localized area 101 will now be described with reference to
The method further includes manipulating the moisture proof barrier 38 to expose the first absorbent pad 32 and the cleaner 34 (
It should be noted that not all of the cleaner 34 may be distributed from the first absorbent pad 32 to the localized area 101 where the spot 100 is located. In addition, some of the spot 100 may be absorbed into the first absorbent pad 32 when the first absorbent pad 32 engages the spot 100 (see
In some embodiments, the moisture proof barrier 38 may include a first layer 42 that is attached to the first absorbent pad 32 and a second layer 43 that is attached to the second absorbent pad 36. When the moisture proof barrier 38 of the spot cleaner 30 includes first and second layers 42, 43, the method may further include inserting a hand 45 between the first layer 42 and the second layer 43 (
It should be noted that holding the first absorbent pad 32 against the localized area 101 may include pressing the first absorbent pad 32 against the localized area 101 using the hand 45 (
The operations discussed above with respect to the described methods may be performed in a different order from those described herein. In addition,
The spot cleaners and methods described herein may allow individuals to quickly and readily clean a spot from a localized area. In addition, the spot cleaners may be formed in multiple sizes and/or include different types of cleaners such that an appropriate size/type of spot cleaner may be selected depending on the size and type of spot, and the type of substrate.
While the invention has been described in detail with respect to the specific aspects thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these aspects which fall within the spirit and scope of the present invention, which should be assessed accordingly to that of the appended claims.
