Cooking and preparing baked and barbecued goods in the home, kitchen and campground generally involve the handling of hot objects such as cookware, pans, pots, plates and other cooking accessories and tools that cannot be safely or comfortably held by hand without some form of protection. However, kitchens are becoming increasingly filled with accessories and tools, having limited storage spaces so that a device or tool that can serve multiple purposes is welcome, saving space as well as providing multiple functions and uses. While kitchen gloves are common and handy accessories, they generally function only as gloves to protect one's hands from hot objects and are not suited for use for other purposes, such as for example, for use as a trivet to protect a susceptible surface, such as a countertop or table, from the same hot object. In addition, after typical and normal use, kitchen gloves can become soiled by liquids, food, food residues, spills and perspiration released by a user's hand, leaving the gloves somewhat unpalatable for the continued use and handling of foods and their containers.
Accordingly, it would be desirable to have a kitchen or barbecue glove that has the capability of providing multiple functions, such as for example, functioning as a glove and as one or more trivets to protect either a user or a surface from contact with a hot or cold object. In addition, it would be desirable to have a kitchen or barbecue glove that has the capability of providing several simultaneous functions, such as for example, functioning as a glove but providing additional properties such as easier cleaning, stain and soil resistance, water and oil resistance and/or repellency, antimicrobial or odor control efficacy, faster drying, and combinations thereof, serving to provide a glove with a cleaner and more sanitary contact surface for the handling of foods and containers, and around food contact surfaces.
More specifically, it would also be desirable to have a kitchen or barbecue glove whose surfaces have the property, either inherently or by means of some suitable treatment applied thereon, to resist or prevent contaminants or stains from adhering thereon, or resist or prevent the attachment, growth and spread of microbial organisms, or alternatively, to ease the removal of such contaminants, stains or microbial organisms from said surface during a cleaning or rinsing procedure applied to restore those surfaces to a clean or pristine condition following use.
Accordingly, one object of the present invention is a convertible insulated glove in the form of two separately attached half sections for the handling of hot or cold objects, one embodiment of the inventive glove fitting either the left or right hand of the user, or the use of two such gloves worn on both hands.
Another object of the present invention is a convertible insulated glove in the form of two separately attached half sections that can be divided into at least two objects that can serve as trivets for the purpose of insulating a susceptible surface, such as a countertop, table or tray, from a hot or cold object.
Another object of the present invention is a convertible insulated glove in the form of two separately attached half sections that can be divided into at least two objects that can serve as mitts each having means for engaging at least one finger of at least one user's hand to enable control and positioning of said mitt for the purpose of insulating a user's fingers or hands from a hot or cold object.
A further object of the present invention is a convertible insulated glove in the form of two separately attached half sections that are constructed of, or whose surfaces thereof have been treated with, a material that serves to resist or prevent contaminants or stains from adhering thereon.
Yet another object of the present invention is a convertible insulated glove in the form of two separately attached half sections that are constructed of, or whose surfaces thereof have been treated with, a material that serves to ease the removal of contaminants or stains from said surfaces during a cleaning or rinsing procedure applied to restore that surface to a clean or pristine condition following use.
Another object of the present invention is a convertible insulated glove in the form of two separately attached half sections that are constructed of, or whose surfaces thereof have been treated with, a material that serves to resist or prevent the attachment, growth and spread of microbial organisms, or alternatively, to ease the removal of microbial organisms and their byproducts, such as stains and odors, from said surface during a cleaning or rinsing procedure applied to restore that surface to a clean or pristine condition following use.

Although a threaded trace 614 is shown in
In addition to those physical and mechanical features and properties disclosed hereinabove relating to the various embodiments of the inventive glove, additional functional features can be employed to improve the performance, handling, cleaning and functionality of the inventive glove. Such functional features include, but are not limited to, treatments applied to one or more of the fabric panels or materials of construction used therein, to provide properties selected from antimicrobial activity, soil resistance, stain resistance, water and oil resistance or repellency, odor control, easier cleaning, faster drying, gripping improvement, and combinations thereof. Treatments and other functional adjuncts that may be used or included in the construction of the panel materials used in making the inventive gloves are discussed in more detail below, as well as insulative materials useful in providing the desired insulative value (R) to the panels.
Construction Details
In one embodiment of the present invention, the two halve sections of the glove are in the form of an approximate mirror-imaged shape with respect to one another, represented by a complementary top and bottom section or half section, which when placed together in an overlapping or coinciding coplanar horizontal position, can be joined together along one outer edge or at least one selected region along said outer edge, by some joinder means capable of attaching the two regions together, to form an integrated glove structure with an internal opening capable of allowing the insertion and retention of at least one or more fingers of a user's hand, or a portion of a user's hand including fingers and thumbs.
In a related embodiment to that disclosed immediately above, the two halve sections of the glove share at least one mirror-imaged shaped section or complementary region enabling joinder of the two half sections to form an integrated structure with at least one common point of attachment or at least one attachment region shared by both of the half sections, forming a planar, open structure that can be positioned to lie flat on a horizontal surface to serve as an insulating trivet, when joined in either fashion. Either of these embodiments has the advantage of producing a connected set of trivets that will stay together and not move apart or become displaced from one another when used to protect a surface from a hot or cold object placed thereon.
In a further related embodiment to that disclosed immediately above, the assembled glove with two connected half sections present may subsequently be completed separated and the two half sections detached from one another to form two physically separate and displaceably separable insulated units, which can themselves be used as individual insulating mitts worn on a hand, or used as two independent insulating trivets.
In the embodiments of the invention disclosed herein, a bias portion or edging feature is desirable along the outer periphery of the half sections of the glove to provide a region along the periphery of the glove to position the attachment or joinder means, such as for example, but not limited to, a zipper or band of hook & loop fastener. Further, the bias feature is desirable to close the otherwise open end of the panel section, particularly in layered constructs, so that the raw edge of any fabric or textile sheet thus employed is not exposed along its periphery. In one embodiment, the bias portion is simply a loop of the fabric or textile sheet material bent back on itself and secured by some means, such as by sewing or bonding, as described herein with regard to the means of producing a quilted pattern in said panel section. In preferred embodiments, the width of the bias portion or edging feature is wide enough to accommodate the attachment of a fastening, attachment or joinder means, such as for example a zipper or band of hook & loop fastener, or some other attachment or joinder means. In some embodiments, the bias portion or edging feature is immediately adjacent and narrowly separated with respect to the periphery of the half section of the inventive glove, while in preferred embodiments, the bias portion or edging feature is immediately adjacent and more widely separated with respect to the periphery of the half section so that when the attachment means is present on the bias portion, the outer edge of the attachment means, for example being a zipper, is more widely separated from the periphery so that at least a small gap is present so that when the two corresponding half sections of the inventive glove are combined, the attachment or joinder means (zipper) does not protrude beyond the periphery of the assembled glove in the first instance, and is further indented or slightly internal to the periphery of the assembled glove in the second, preferred instance. In the preferred embodiment thus described, a metal zipper would be at least slightly internally displaced along the bias portion so that no part of the zipper in either half section or in the assembled glove would protrude or be near the outer periphery of the half section or glove, reducing the chance of contact between the metal zipper and a user's hand, thus avoiding the chance of a user's hand or appendage thereof touching the zipper during use, because metal materials are well known heat and cold conductors and being located on the periphery could reasonably be expected to be exposed to the heat or cold source during use.
However, in embodiments employing non-metallic attachment means, including hook & look fasteners and plastic zippers, for example, the attachment or joinder means can be placed immediately adjacent to, and even positioned to slightly protrude beyond the periphery of the half section or assembled glove, as there would then be a much lesser danger of undesirable heat or cold transfer to a user's hand or appendage owing to the attachment or joinder means.
Joinder Means
In one embodiment of the present invention, the two half sections of the glove are in the form of a mirror-imaged shape with respect to one another as described herein, with complementary outer edges capable of being reversibly joined, and which are joined together at least at one position along said outer edges, by an attachment (joinder) means capable of at least holding the two half sections together during physical manipulation as a glove or as a trivet. In a related embodiment of the present invention to that described immediately above, the two half sections of the glove are not mirror-imaged shapes but have at least on complementary outer edge or a portion thereof that is capable of being reversibly joined together by said joinder means, sufficient to hold the two half sections together during physical manipulation as a unit, such as for example but not limited to, a trivet, pot holder, tray holder, placemat, and the like.
Suitable joinder means include common approaches disclosed in the art such as, but not limited to, buttons, Velcro™ (a product of the 3M Company, located at 3M Center, St. Paul, Minn. 55144-1000, USA), hook-and-loop complementary fabrics, friction seams, magnets, magnets and keepers, snaps, ties and zippers, and combinations thereof.
In one embodiment of the present invention, a zipper is used as the joinder means, one section of the zipper trace being attached to the peripheral area of a first halve of the glove and the second complementary section of the zipper trace with the securing pull tab present being attached to a second peripheral area of the second complementary halve of the glove, in a position enabling the joining of the two sections of the zipper trace to be interconnected by means of sliding the securing pull tab from a first engagement position to an intermediate or terminal position, wherein the securing pull tab acts to interweave the corresponding teeth of said two sections of zipper trace into an interconnected unit.
The zipper can be made from any suitable material or combination of materials, including metal, plastic, polymers, resins, and combinations thereof. The zipper can be cut, formed, molded, cast, forged, pressed or be made by any known manufacturing method. The attachment of the zipper to one or more panels of the glove can be done by means of sewing, gluing, bonding or the use any suitable bonding technique or any combination of techniques, such as for example, but not limited to, thermal and compression melt bonding. In preferred embodiments, the zipper is heat resistant and made from a material of construction chosen that will not significantly soften or melt at temperatures up to about 500° F.
Friction seams include those molded, complementary barb and channel style reversible fastening means used with or without sliders on the plastic panels of Ziploc™ storage bags (Ziploc™ products available from S.C. Johnson & Sons, 1525 Howe Street Racine, Wis. 53403-5011, USA and shown, for example in U.S. Pat. No. 7,029,178 entitled “Zip-lock closure”, which is hereby incorporated in its entirety by reference) and to enable (re)closing of the bags. In preferred embodiments, the friction seam components are heat resistant and made from a material of construction chosen that will not significantly soften or melt at temperatures up to about 500° F.
Magnets and keepers include a patterned combination of at least one magnet and at least one ferrous or iron-containing metal object that is attracted to said magnet forming a reversible coupling. In inventive embodiments employing magnets and keepers, a plurality of each are patterned in such a manner as to enable a desired coupling overlap so that select portions of each halve of said glove bearing said plurality of magnets and keepers is joined in a manner complementary to said pattern, so that the two half sections of the glove removably connect to each other by magnetic attraction but only in a manner consistent with said pattern, so that the combined whole glove is configured by joining to form a desired and consistent glove. For example, the pattern ensures that the thumb portions and finger portions of the complementary half sections join together properly to form a pocket for a thumb or at least one finger of the user, and variations thereof.
In some embodiments of the present invention intended for the handling of higher temperature extremes of hot and cold objects, the presence of exposed metal components may product heat or cold conductive sites that might produce discomfort or injury to the user, so that in these instances, a joinder means such as a zipper or snap is preferably present in the form of a non-metallic connector, such as for example, but not limited to, plastic, polymer, resin or composite materials of construction with lower heat conductivity or transmission than a typical metal such as iron, brass, copper, steel or the like. In embodiments employing magnets and metallic keepers, one preferred option is to have the metal element coated, covered by a fabric panel of the glove, or covered by an additional fabric element so that the surface of the magnet or metallic keeper is protected from direct contact with an object or the skin or flesh of a user of the glove, so as to prevent or reduce heat transfer through the metal element. In one embodiment, magnets and metallic keepers are coated with a thin coating of an adherent plastic, polymer or silicone film that is resilient but provides a heat insulating barrier to the metallic element.
In other embodiments of the present invention, one or more magnets or one or more sets of magnet and keepers can be employed solely for the purpose of facilitating the proper complementary positions of the two initially separated half sections of the glove into a mutually aligned position in which the start of the two zipper traces are approximately aligned in a position from which they can then be more easily interconnected at the start of the zipper trace, as well as facilitating the interlocking of the two zipper traces as the zipper pull tab is progressively moved along the zipper trace located along the bias portion located near the outer periphery of the two half sections of the glove to form the assembled glove, leaving the unattached remaining portion (opening) of the assembled glove open to enable hand insertion.

Synthetic fibers and materials include, but are not limited to, polymers and copolymers that are produced by chemical means, and which can be mechanically or heat treated to form fibers and threads, and which are subsequently formed into stitched, woven, knitted, knotted, yarned or otherwise entangled planar sheets of textile or cloth panels, or alternatively may be formed into entangled planar sheets by non-woven means including air laid, water laid, electrostatic or dynamic fiber entanglement means when the source fiber is process directly in a partially softened, flowable or melted state in the form of said source fiber, by means of any suitable process common in the art. Non-limiting examples of suitable synthetic materials include nylon, polyester, polyacrylamide, and the like, as well as other synthetic polymers known in the art such as fluorocarbon and silicone based materials such as Teflon™ (a registered trademark of the Dupont Company), perfluoropolyethylene, polysiloxane, silicones, and the like.
In addition, embodiments of the invention can employ materials of construction that have been optionally treated by a second material or process, such as for example, but not limited to, a chemical material or compound, reactive species, coating, treatment process, such as exposure to heat, plasma or ionizing radiation, in order to provide a secondary benefit to said materials. Such second material classes that can provide such secondary benefits include, but are not limited to antimicrobials, disinfectants, anti-soiling agents, odor control agents, oil and water repellants, gripping aids to prevent slippage, and combinations thereof. Such treatment processes include those employing exposure of the outer surface of said materials of construction by means of heat, plasma or ionizing radiation in order to alter the surface properties in a favorable way to achieve a benefit as described herein.
In embodiments of the present invention, planar sheets of textile or cloth panels are used singly or in combination to form the walls and gripping surfaces of the glove. One or a plurality of panels are suitably employed, the nature and thickness of the panel(s) being selected for the application. In general in most embodiments, better heat and cold resistance is achieved by increasing the thickness of the panel to achieve some minimum insulation value, denoted by the heat transmission or insulative factor, R.
In other embodiments of the present invention, multiple sheets of textiles or panels are combined into a construct with at least one exterior layer and at least one insulating layer in contact therewith, wherein the purpose of said insulating layer is to provide the insulation value of the construct while the exterior layer is selected to primarily provide a covering means, and secondarily to provide one or more secondary benefits as described herein.
In one embodiment of the present invention, a single layer of material having sufficient insulating properties may be employed to form one or more panels of the glove or portion thereof. Materials having suitable insulating properties in sheet form include, but are not limited to, batting, down, foam, feathers, fluff, fleece, fuzz, lint, eiderdown, feathers, floss, sponge and combinations thereof, including both naturally derived and synthetically manufactured versions thereof. These preceding materials may be present in a layered construct, or present as bits or pieces of the materials assembled or compressed to form a bulk collective thereof suitable for encapsulation by one or more layers of a second material that can hold or trap in place the assembled or compressed form of the insulating materials. In preferred embodiments, the insulating material is selected to have a high heat and cold insulation factor, R, wherein higher values of R correspond to greater insulative properties.
In other embodiments of the present invention, materials used for their insulative properties include foams, micro-foams and closed-cell foams make from polymeric materials that may be selected from, but not limited to, ethylene-vinyl acetate (EVA) foam, the copolymers of ethylene and vinyl acetate; low-density polyethylene (LDPE) foam, polyethylene (PE), nitrile rubber (NBR) foam, the copolymers of acrylonitrile (ACN) and butadiene, polychloroprene foam, neoprene, polyimide foam, polypropylene (PP) foam, including expanded polypropylene (EPP) and polypropylene paper (PPP), polystyrene (PS) foam, including expanded polystyrene (EPS), extruded polystyrene foam (XPS) and polystyrene paper (PSP), styrofoam, including extruded polystyrene foam (XPS) and expanded polystyrene (EPS), polyurethane (PU) foam, low-resilience polyurethane (LRPu), memory foam, sorbothane, polyvinyl chloride (PVC) foam, closed-cell PVC foamboard, silicone foam, microcellular foam and other polymer and copolymer materials that can be blown into an open or closed-cell cellular foam structure with some degree of flexibility suitable for the manipulation of objects when constructed as a glove panel according to the inventive disclosure herein.
The materials of construction can be employed in any desired thickness, combined and layered in any suitable pattern or combination of layers, and can include treated materials as discussed hereinbelow to provide additional functional properties in addition to a least one insulative property.
In alternative embodiments of the present invention, one or a plurality of layers of an insulating material can be employed to raise the R value of a glove panel.
In other embodiments of the present invention, insulating material of various thickness or bulk can be covered by a first, or alternatively, first and second outer layer, to form an encapsulated insulated construct in which the insulating material is protected by said first or first and second outer layer.
In another embodiment of the present invention, a plurality of layers of material having sufficient insulating properties may be layered or otherwise combined in a manner to form one or more panels of the glove or portion thereof.
In another related embodiment of the present invention, a layer of insulating material can be combined with one or more additional layers of a panel material, such as a sheet of textile or cloth, attached to at least one side or on both sides of said insulating material layer, to protect said insulating material from direct contact or exposure to objects in contact with the glove. In embodiments of the present invention employing this optional construction approach, this single layering or sandwich layering enables any insulating material layers present in these embodiments to remain clean and not be directly exposed to liquids, foods or soils during use.
In a further embodiment of the present invention, one or two layers of an exterior sheet of textile or cloth can be joined to one side or two sides, respectively, of a layer of insulating material by some attachment or connection means, including but not limited to, processing such as gluing, thermal bonding, quilting, sewing, stitching, tacking and combinations thereof.
In a preferred embodiment, quilting of a layered insulating material enables the formation of hills and valleys, being the high loft and low loft points where the sewn quilted construction is either free of stitching or is stitched, respectively. This embodiment of the present invention adds thickness to the layered insulating material construction, and produces an additional insulating effect by means of forming multiple air channels or paths corresponding to the stitched pattern that traps air when the surface of the layered construct is brought into contact with a hot or cold object. A further advantage of a quilted layered insulating construction is to increase surface friction and thereby improve the gripability of the material, that is to aid the ability of the user of the assembled glove or one or more unassembled glove half sections to pick up and hold onto objects without slippage.
Pockets for engaging one or more of a user's appendage, including one or more fingers, thumb, palm and wrist, and combinations thereof as disclosed hereinabove in embodiments of the invention relating to those discussed with
Material Treatment Means
In some embodiments of the present invention it is desirable to treat the surfaces of the glove, including the exterior (outer) and interior (inner) surfaces thereof, by some treatment means capable of providing the treated surface with an additional benefit or functionality.
In one embodiment, a stain or soil resistant finish may be applied in order to reduce or prevent the staining of the glove by foods, liquids and other residues encountered during use. Conventional stain and soil resistant and stain-proofing treatments known in the art are quite suitable for use with the present invention, including such treatment materials based for example, but not limited to, on hydrocarbons, fluorochemicals, silicones, polysiloxanes, siloxanes, polymers, copolymers, waxes, and combinations thereof.
These and related materials known in the art may be employed alone, or in combination, to achieve one or more functional benefits selected from, but not limited to, as easier cleaning, stain and soil resistance, water and oil resistance and/or repellency, antimicrobial or odor control efficacy, faster drying, gripping improvement, and combinations thereof.
In one embodiment, the panels used to construct the present invention, or at least the surfaces of said panels or materials of construction, are treated with a colloidal or nano-particle based silver biocidal agent or treatment means that provides some degree of odor control, biocidal efficacy and/or antistatic and anti-microbial benefit to the inventive glove.
In other embodiments of the present invention, it is desirable to apply a flame-resistant or flame-retardant material to one or more surfaces of the glove, or to materials of construction including the insulation, fabric layers, thread, yarn and other absorptive materials used, suitably using those flame-retardant materials know in the art, and most preferentially employing those that are safe for use around foods, food contact items and humans.
In further embodiments of the present invention in which a treatment means is applied, the treatment agent can be applied to the materials prior to construction, or alternatively, applied after construction of the glove, or in parts prior to and after construction of the glove, as desired to maximize the desired benefit while reducing the amount of treatment agent needed. In these embodiments, the treatment agent can be applied by any appropriate means as required to affect the treatment, such as for example, but not limited to, application by means of a gas, liquid, or solid treatment agent applied to said construction materials by means appropriate to said treatment agent, including but not limited to, dipping, infusion, melt, submersion, spraying or wet-laid contact methods commonly known in the art.
In one embodiment of the present invention, materials of construction of the glove used to produce the panels maybe treated with an agent that can reduce, control, eliminate or prevent the growth of microorganisms, including for example, but not limited to archaea, bacteria, fungus, mildew, mold, microbes, prions and viruses.
