1. Technical Field
The present invention relates to pet hair collectors for removing pet hair from, for example, all fabrics, and objects with fabric, clothing, pillows, comforters, furniture, etc., and to materials for use in various applications requiring a firm grip, such as athletic applications.
2. Background of the Invention
Pets, such as dogs and cats, accumulate and shed a significant amount of hair. Various vacuums and other apparatuses have been developed to address pet hair accumulation in the caretaker's house. However, such machines are often expensive and not fully efficacious in removing pet hair.
U.S. Pat. No. 6,024,970 (“the '970 patent”) describes a disposable lint mitt that includes an adhesive. There is no mention in the '970 patent that the mitt would be efficacious in removing pet hair. Moreover, because the mitt of the '970 patent includes an adhesive, it can only be used one time before it must be discarded.
U.S. Pat. No. 6,460,191 (“the '191 patent”) describes a disposable, paw-shaped pet hair removal glove that includes a strong adhesive on the palm side. Because the glove of the '191 patent uses an adhesive, like the mitt of the '970 patent, it can be used only one time and must include a protective film covering to protect the adhesive before use.
U.S. Design Pat. No. 466,662 (“the '662 patent”) is by the same inventor as the '191 patent and was filed on the same day. There is no discussion in the '662 patent on the composition of the glove disclosed therein.
Finally, Petco Animal Supplies, Inc. (San Diego, Calif.) sells the Evercare Pet Hair Pic-Up Mitt. According to user reviews of the product, the mitt is not efficacious in removing some types of pet hair (such as short hair) and is not efficacious removing pet hair from some objects. In addition, the mitt is not form-fitting.
Various non-glove products exist for removing pet hair. For example, two products are marketed through infomercials as the SCHTICKY and STICKY BUDDY. Each product is advertised as including a reusable lint roller and claims to be effective at removing lint and pet hair. The roller for the SCHTICKY is advertised as being silicone-based, while the roller for the STICKY BUDDY is described as being made out of silicone rubber. Both rollers are advertised as being washable. However, roller-based products are not suitable and/or desirable for many applications, can be used only on flat surfaces and cannot remove pet hair from corners, cracks and crevices.
Thus, there remains a continuing need for apparatuses to pick-up pet hair.
Various products have also been proposed for enhancing the grip of the user, such as athletic participants, construction workers, and/or the like. These products include gloves, grip covers, and/or the like. However, many of these products are too bulky and/or thick for many users and/or applications.
The present disclosure relates to apparatuses configured to collect pet hair and/or enhance the grip of a user.
In some embodiments, the present disclosure provides a wearable hand covering, such as a glove, for removing pet hair and/or enhancing the grip of a user. In some embodiments, the glove is a form-fitting glove with elastic properties so that the glove can stretch or contract based on the size of the human user's hand and fingers, thereby providing increased dexterity and/or control for the user over prior art products. In some embodiments, at least a portion of the glove, such as a palm portion of the glove, is sticky to the touch (e.g., tacky). Additionally, the glove works, at least in part, via an electrostatic charging attraction between the glove and the pet hair. In some embodiments, the glove is a coated glove that includes a plurality of fingers configured to receive fingers of a human, a palm portion configured to cover the human's palm when the human's fingers are inserted into the plurality of fingers, a back hand portion configured to cover the back of the human's hand when the human's fingers are inserted into the plurality of fingers and a glove opening defined by the back hand portion and the palm portion at a side opposite to the plurality of fingers so that the human's hand can be inserted through the glove opening. In some embodiments, the glove is comprised of a fabric. In some embodiments, the fabric is a fiber such as nylon, spandex (elastane) and/or bamboo.
In some embodiments, the glove further includes a coating comprising a nitrile and/or a silicone bound to the fabric or other material making up the glove. In some embodiments, the nitrile is poly(butadiene-co-acrylonitrile). In some embodiments, the nitrile has a Mooney viscosity of between about 30 and about 50 MU when determined according to ISO 289. In some embodiments, the coating further includes an emulsifier/wetting agent, such as octylphenol ethoxylate, sodium dihexylsulphosuccinate or sodium 4-(5-dodecyl)benzenesolfonate, an antioxidant, such as N,N′-di-sec-butyl-p-phenylenediamine, a filler, such as clay or titanium oxide and/or solvent(s) such as water, ethanol or 2-butanone. In some embodiments, the nitrile is adhered to the first material via an adhesive. In some embodiments, the nitrile is induced to bond to the supporting fabric glove by use of a coagulant such as calcium nitrate that can be supplemented with calcium carbonate. In some embodiments, the coating substantially covers at least the palm portion of the first material. In some embodiments, the coating substantially covers only the palm portion of the first material.
In some embodiments, the glove may or may not include fingers. In such embodiments, the glove may be a coated glove that includes a glove comprising a plurality of finger openings configured to allow a human's fingers to pass there through; a palm portion adjacent to the plurality of finger openings and configured to cover a human's palm when the human's fingers are inserted through the finger openings; a back hand portion configured to cover the back of the human's hand when the human's fingers are inserted through the finger openings; and a glove opening defined by the back hand portion and the palm portion at a side opposite to the finger openings so that the human's hand can be inserted through the glove opening, the glove comprised of a first material. Preferably, the glove includes a coating bound to the first material.

In some embodiments, the glove 10 is a coated glove that includes a plurality of finger openings 11 that may lead to a plurality of fingers 12 configured to receive fingers of a human, a palm portion 14 configured to cover the human's palm when the human's fingers are inserted through the plurality of finger openings 11 and optionally into the plurality of fingers 12, a back hand portion 16 configured to cover the back of the human's hand when the human's fingers are inserted through the finger openings 11 and optionally into the plurality of fingers 12 and a glove opening 18 defined by the back hand portion 16 and the palm portion 14 at a side opposite to the plurality of finger openings 11 so that the human's hand can be inserted through the glove opening 18. In some embodiments, the glove 10 includes five fingers 12 as shown in the illustrations in order to accommodate the thumb and four fingers of a human's hand. In other embodiments, the glove 10 may be a mitt that includes a first finger 12 for the human's thumb and a second finger 12 for the four other fingers of a human's hand. In still other embodiments, the glove 10 may be a fingerless glove that lacks fingers 12. Preferably, however, the glove 10 includes a plurality of fingers 12. It is further preferred that the glove 10 is form-fitting and elastic so that the glove can accommodate users having various sized fingers and hands. The glove 10 also can provide increased dexterity and/or control for the user (e.g., the user can grab, and get into areas (cracks, crevices, etc.)) whereas other prior art products do not enable such uses.
The glove 10 is comprised of a first material, which may be, for example, a fabric comprised of a plurality of fibers such as a polyamide. In some embodiments, the polyamide is nylon. In addition to, or instead of nylon, the first material may be comprised of spandex (elastane) or bamboo.
In some embodiments, at least a portion of the glove 10, such as a palm portion 14 of the glove 10, is sticky to the touch (e.g., tacky). In some embodiments, the coated glove 10 further includes a coating 20 bound to the first material. In some embodiments the coating is a nitrile and/or a silicone. As known to those of ordinary skill, a nitrile is a chemical compound with carbon triple bonded to nitrogen. Preferably, the nitrile is a nitrile polymer. In some embodiments, the nitrile is poly(butadiene-co-acrylonitrile), alone or in combination with other nitriles. In some embodiments, the coating 20 further includes an emulsifier such as octylphenol ethoxylate, a wetting agent, an antioxidant, a filler or solvent. In some embodiments, the nitrile is adhered to the first material of the glove 10 via an adhesive, such as dodecyl acrylate or another acrylic adhesive such as poly(vinyl)acrylate. Preferably, if included, the adhesive is covered by the coating so that the glove is not too tacky. In some embodiments, the coating 20 substantially covers at least the palm portion 14 of the glove 10. Preferably, prior to use, the coating is dried—i.e., not wet.
Nitrile synthetic tri-polymers display similar characteristics to rubber once they have been vulcanized (a process where the latex film is heated, and the curing or vulcanizing mixture, typically a combination of sulfur, accelerator and heat cause cross-linking of the rubber, giving strength and elasticity to the film). Nitrile also has no natural rubber proteins and therefore eliminates the well-documented protein risks associated with natural rubber latex. Nitrile conforms to the shape of wearer's hands, has good puncture resistance, greater chemical protection and, because it contains no latex proteins, Type 1 Latex Allergy is eliminated. Preferably, the glove 10 is hypoallergenic.
The present disclosure also provides a method of using a substrate described herein, such as the glove 10, to remove pet hair. In some embodiments, the method includes a) providing the glove 10; and b) removing the pet hair with the glove 10. In some embodiments, the pet hair is removed by putting the object (e.g., the human's clothes, fabrics, pillows, comforters or furniture) in contact with the glove 10, preferably with the portion of the glove 10 that includes the coating 20 (e.g., with the palm portion 14). In some embodiments, the object is brushed or swiped with the glove 10. In some embodiments, the method can further include washing the glove 10 (e.g., with water) and reusing the glove 10 to remove pet hair.
The present disclosure also provides a method of making a substrate described herein, such as the glove 10. In some embodiments, at least a portion of the glove 10, such as the palm portion 14 of the glove 10, is sticky to the touch (e.g., tacky). In some embodiments, the method includes a) providing a glove 10 that includes a plurality of finger openings 11 that optionally lead to a plurality of fingers 12 configured to receive fingers of a human, a palm portion 14 configured to cover the human's palm when the human's fingers are inserted into the plurality of finger openings 11, a back hand portion 16 configured to cover the back of the human's hand when the human's fingers are inserted into the plurality of finger openings 11, a glove opening 18 defined by the back hand portion 16 and the palm portion 14 at a side opposite to the plurality of openings 11 so that the human's hand can be inserted through the glove opening 18, and the glove 10 is comprised of a first material; b) applying (e.g., by dipping the glove 10 in) a coating composition comprising a silicone and/or a nitrile to provide a coated glove 10; and c) partially but not completely curing the coated glove 10 by, for example, heating the glove 10 or leaving the glove 10 at room temperature so that the coating is partially cross-linked. In some embodiments, the glove 10 is a fingerless glove that lacks fingers 12, as described herein. In some embodiments, the method further includes applying a thinner to the glove 10 and/or the coating composition prior to step b) and/or applying an adhesive to the glove 10 and/or the coating composition prior to step b). Without being bound by any particular theory, it has been observed that if the glove 10 is completely cured (dried), the glove 10 loses its effectiveness (e.g., tackiness). It has also been observed that if the glove 10 is not sufficiently cured, the glove 10 is too tacky and breaks apart. Thinners that may be used in conjunction with the present invention include, for example, water, alcohols such as ethanol, isopropanol, and 1-methoxy-2-propanol, tetrahydrofuran, 1,4-dioxane and propylene glycol monomethyl ether. Optionally, the method further includes adding a tackifier (e.g., rosin) to at least one of the glove and the coating composition prior to step b).
Partially curing the glove 10 may be accomplished by, for example, reducing the temperature of curing, the time of the curing process, the composition of the curing agent, the amount of the curing agent, or by chemically neutralizing the curing agent before full cure is achieved. In some embodiments, the glove 10 is cured at between about 0 and about 75% of the recommended curing temperature of the nitrile or silicone coating 20. In another embodiment, the glove is cured between about 25% and 50% of the recommended curing temperature of the nitrile or silicone coating 20. In another embodiment, the glove 10 is cured between about 50% and about 75% of the recommended curing temperature of the nitrile or silicone coating 20. Optionally, the coating has a thickness of between about 50 and about 250 microns. The thickness of five total locations on gloves prepared using a method described herein was measured and it was determined that the coating had a thickness of between about 78 and about 198 microns.
Preferably, the glove 10 is not washed after step c). As known to those of ordinary skill, nitrile gloves in the prior art are typically washed after curing to remove impurities. In the instant application, however, where an initially tacky, nitrile glove 10 is desired, it is advantageous to keep the impurities, which may add to the initial tackiness and/or electrostatic properties of the glove 10. While the glove 10 is described as having an initial tackiness, the inventor has found that the glove 10 remains effective at removing pet hair from a plethora of surfaces even after the tackiness is reduced after one or many uses of the glove 10. In an embodiment, a surface of the glove can be rough and non-uniform (e.g., vary by approximately 100 to approximately 200 microns), which can assist with entanglement by grabbing hairs and dragging them around.
In some embodiments, the coating composition 20 is supplemented with one or more components found in the SCHTICKY roller (Square One Entertainment, Inc., Miami Beach, Fla.).
Without being bound by any particular theory, it is believed that the coated glove 10 collects pet hair by being slightly tacky and also due to electrostatic charging between the glove 10 and pet hair. Electrostatic charging refers to the phenomena observed when two materials with neutrally charged surfaces come into contact (<4 angstroms) and then separate, the materials undergo tribocharging and acquire a non-neutral surface charge level. The level and polarity of this newly acquired surface charge is dependent on several factors, but can be relatively answered by considering the triboelectric series. A material such as glass that comes into contact with a vinyl material will acquire a more positive charge because it is near the more positive position in the triboelectric series relative to the position of vinyl. Alternately, the vinyl will acquire a more negative charge following the same logic. The fact that these two materials are far apart from each other in the series may result in a larger charge level generated than if the glass came into contact with, for example, aluminum.
In the case of the present invention, without being bound by any particular theory, it is believed that when the glove 10 contacts pet hair, the pet hair becomes more positively charged and the nitrile or silicone becomes more negatively charged. Optionally, the nitrile or silicone can be modified to contain carboxyl groups. In some embodiments the nitrile or silicone contains about 1-10% carboxyl groups. In an embodiment, a nitrile contains 7% carboxyl groups. It has been observed that when pet hair is collected by the coated gloves 10, the pet hair tends to stick to itself (coadhere/ball up) on the glove 10. Without being bound by any particular theory, it is believed that friction between the pet hair and the nitrile causes electrons (negatively charges particles) to move from the pet hair to the nitrile. This leaves the nitrile with excess electrons and thus a negative charge and the pet hair with a deficit and a positive charge. Since opposite charges attract, the pet hair clings to the nitrile. In addition, because similar charges repel, once charged there will be a repulsive force between individual pet hairs. However, in the glove 10, the pet hairs roll up and become entangled/ball up, which overwhelms the repulsive force between the individual pet hairs and causes the individual hairs to stick together. Preferably, the coated glove 10 is configured to adhere to pet hair. For purposes of the present invention, the term “adhere to pet hair” when used in conjunction with the coated glove 10 means that the coated glove 10 adheres to most if not all cat hair and at least some types of dog hair, especially long-haired dogs, it being understood that the coated glove 10 need not adhere to all types of dog or cat hair. For example, to date, it has been observed that the coated glove 10 of Examples 1 and 2 adheres to all cat hair but is not particularly efficacious in adhering to the short, wiry hair of some dogs.

In still other embodiments, the pet hair collector is a removable covering for various types of cleaning instruments. For example, the pet hair collector can comprise a substrate described herein with an elastic opening for selectively covering and uncovering a surface of a cleaning instrument. Alternatively, the pet hair collector can be a substantially rectangular material that can be held by a user and/or applied to a surface of a cleaning instrument using any solution during use. For example, the cleaning instrument can include one or more features described in U.S. Pat. No. 6,305,046, the contents of which are incorporated by reference in their entirety. Still further, the pet hair collector can comprise a surface of a handled cleaning instrument, which can allow for more ready cleaning of various surfaces, such as flooring (e.g., below furniture), and/or the like.
In other embodiments, the pet hair collector includes a cleaning instrument with one or more removable coverings. For example the cleaning instrument can include a handle 38, a cleaning surface (e.g., the roller 30, a mop head, and/or the like), and a pivotal and/or rotatable attachment mechanism (e.g., a pivot pin 34 and a bracket 36, a universal joint, and/or the like) attaching the handle 38 to the cleaning surface. The cleaning instrument can further include one or more removable coverings described herein for use in conjunction with the cleaning instrument. In some embodiments, the removable covering is sized with respect to a cleaning surface and has elastic properties that require it to stretch when placed over the cleaning surface.

The present disclosure also provides a method of using a substrate described herein, such as the glove 10, a grip cover, and/or the like, to enhance a grip of a user. In some embodiments, the method includes a) providing the glove 10; and b) wearing the glove 10 while performing an activity for which an enhanced grip is desired. In some embodiments, the activity is a part of participating in a sporting event. In some embodiments, participation in the sporting event includes one or more of: holding a ball, catching a ball, or throwing a ball. Illustrative sporting events include: American football, rugby, Australian rules football, basketball, and/or the like. In some embodiments, participation in the sporting event includes gripping a handle. Illustrative sporting events include: baseball, hockey, tennis, golf, lacrosse, bicycling, auto racing, and/or the like. In some embodiments, the activity is gripping a tool as part of utilizing the tool. Illustrative tools include: hammer, screwdriver, steering wheel, saw, various power tools, and/or the like. In some embodiments, the method can further include washing the glove 10 (e.g., with water) and reusing the glove 10 to perform an activity for which an enhanced grip is desired.
The inventor has found that embodiments of the glove 10 described herein can provide one or more of numerous advantages over gloves available in the prior art. For example, an embodiment of the glove 10 that is only partially cured (e.g., includes partially cross-linked nitrile) can provide a tacky grip, whereas many prior art gloves are fabricated of a material that can easily slip in certain conditions. An embodiment of the glove 10 having a roughened outer surface can provide the user with a more tight, firm, and/or non-slip grip, whereas many prior art gloves do not. An embodiment of the glove 10 manufactured from a single layer of a woven, flexible fabric can be breathable, lightweight, form fitting, and/or washable, whereas many prior art gloves are fabricated from a material that does not breath (e.g., leather), is substantially thicker, and/or is not stretchable. Embodiments of the glove 10 including any combination of two or more of these features and/or one or more additional features can provide additional advantages including, for example, a more comfortable grip; an ability for the user to keep the glove on between uses (e.g., between golf swings); an ability for the user to feel the action of the activity; and/or the like. Embodiments of the glove 10 also have other ancillary benefits over many gloves of the prior art including, for example: remaining soft; never shrinking; more pliable; non-wrinkle; more readily placed in pocket; does not retain water (e.g., get saturated unlike leather); and/or the like. It is understood that while these advantages have been described in conjunction with a glove 10, similar advantages can be attained from embodiments of a material described herein utilized in different configurations, e.g., as a grip cover for an instrument.
The following examples are provided to illustrate some embodiments of the glove 10 of the present disclosure but should not be interpreted as any limitation thereon. Other embodiments within the scope of the claims herein will be apparent to one skilled in the art from the consideration of the specification or the apparatuses or methods disclosed herein. It is intended that the specification, together with the examples, be considered to be exemplary only, with the scope and spirit of the disclosure being indicated by the claims which follow the examples.
Zeon LX 550 nitrile (Zeon Corporation, Tokyo, Japan), a partially carboxylated nitrile (approximately 7%) was mixed with a curing package that included 0.06%, 0.1% sulfur zinc oxide, and 0.1% titanium dioxide to form a coating composition. The coating composition was thinned with a solvent.
Nylon and spandex-mixed gloves were placed on Teflon-coated hand molds and then dipped into a coagulant that included 35% calcium nitrate and the coating composition so that the coating composition covered the palm portion of the gloves. The gloves were then dipped into a water wash to partially cure the gloves and cool the nitrile. The gloves were then heated/dried and cured 50-60% of the nitrile manufacture's recommended condition for complete curing. (The manufacturer recommended 120° C. for 20 minutes for complete curing). The gloves were not washed after the drying process and were found to be efficacious in removing pet hair, creating an electrostatic charge and tackiness.
