The present invention relates generally to devices and methods for disposing of waste, and, more particularly, to gloves for protecting a wearer and/or for facilitating disposal of waste, and to methods for making and using them.
Surgical or examination gloves are often used by doctors, nurses, and other health care professionals. For example, such gloves may be formed from elastomeric material, e.g., latex, natural or synthetic rubber, and the like, to provide tight-fitting, flexible gloves that may protect the wearer from contact with blood or other bodily fluids, medications, contaminants, or other materials. After use, e.g., after examining an individual patient or completing a desired procedure, the gloves may be removed, which may result in the glove being at least partially inverted because of the tight fit around the wearer's hand. Despite being inverted, the gloves may have fluids or other material thereon, which may leak or otherwise exposed others to hazards associated with the material, such as disease, contaminants, corrosive and/or toxic substances, and the like, e.g., until the gloves are properly disposed of in an appropriate container.
Surgical or examination gloves may be made using a dipping process, e.g., by initially providing a form or mold corresponding to the desired shape of the gloves. The form may be dipped successively into one or more materials, e.g., into tanks or other containers, to build up one or more desired layers of material for each of the gloves. Optionally, the form may be heated, dried, and the like, e.g., to cure the materials applied to form after being dipped into one or more of the tanks. After the form is dipped into the tanks and/or otherwise treated, the resulting glove is stripped from the form, and the process may be repeated. Optionally, powder or other materials may be applied to the glove before being stripped from the form, e.g., to facilitate inserting a hand into the glove and/or to reduce slippage between the glove and the wearer's hand.
Exemplary methods for making surgical gloves may be found in U.S. Pat. Nos. 3,852,826, 5,421,033, and 5,612,083. U.S. Pat. No. 3,852,826 discloses applying a colored band to a cuff of surgical gloves to identify the size of the glove, e.g., to avoid glove size mismatching during packaging and erroneous selection by the wearer. U.S. Pat. No. 5,421,033 discloses health-care gloves that include visual indicia along one side edge of the glove, e.g., for identifying the location of the thumb or pinkie finger member.
The present invention is directed to devices and methods for disposing of waste, and, more particularly, to gloves that may protect a wearer and/or may be used as a waste receptacle or other may facilitate disposal of waste, and to methods for making and using them.
In accordance with one embodiment, a device is provided for disposing of waste that includes a glove including an open end or cuff and a plurality of finger pockets for receiving fingers of a hand inserted into the open end, and a closure on the open end. The glove may be sufficiently flexible to be inverted upon removal from a hand of a wearer, and the closure may be configured for substantially closing the open end when the glove is inverted.
In one embodiment, the closure may include a channel extending along a portion of the open end, and a hook, bead, or other protrusion extending along a portion of the open end generally opposite the channel before the glove is inverted. The channel and protrusion, e.g., together providing a zip-lock connector, may be oriented towards one another when the glove is inverted such that the protrusion may be received in the channel to substantially close the open end. In another embodiment, the closure may include a drawstring around the open end that may be tightened to substantially close the open end. In yet another embodiment, the closure may include a strap including a first end attached to the glove and a second loose end that is attachable to another location on the glove for substantially closing the open end.
Optionally, the device may include a handle adjacent the open end for carrying the device, e.g., after the glove is inverted. In addition or alternatively, a pattern may be provided on at least an inside surface of the glove that may be exposed when the glove is inverted. For example, the pattern may include a decorative pattern printed, embossed, or otherwise applied to the inside surface, e.g., one or more inks, dyes, or other colored pigments.
The glove may be formed from an elastomeric material, e.g., latex, natural and/or synthetic rubber, e.g., in one or more layers. In addition, the glove may have a shape or configuration, e.g., cuff length, similar to examination and/or surgical gloves. The glove may be sized to be tight-fitting around a hand inserted into the glove, yet sufficiently flexible to facilitate removal from the wearer's hand, and/or capturing waste material within the glove as it is inverted and removed from the wearer's hand.
In accordance with another embodiment, a device is provided for disposing of waste that includes a glove including an open end and a plurality of finger pockets for receiving fingers of a hand inserted into the open end, the glove being sufficiently flexible to be inverted upon removal from the hand. The device also may include a channel extending along a portion of the open end, and a hook, bead, or other protrusion extending along a portion of the open end generally opposite the channel before the glove is inverted, the channel and protrusion being oriented towards one another when the glove is inverted such that the protrusion may be received in the channel to substantially close the open end.
For example, the channel may be provided in a first elongate strip attached to an outer surface of the glove, and the protrusion may be provided on a second elongate strip attached to an outer surface of the glove generally opposite the first elongate strip. The first and second elongate strips may extend substantially parallel to an edge of the glove defining the open end, e.g., around a portion of the cuff of the glove. Alternatively, the channel and the protrusion may be molded into an edge of the glove defining the open end, e.g., such that the channel and protrusion are oriented away from one another before the glove is inverted.
The channel and protrusion may be configured such that the protrusion is substantially permanently secured in the channel when the protrusion is received in the channel, e.g., to substantially permanently close the open end after waste is received within the glove. Alternatively, the protrusion may be removable from the channel, e.g., if it is desired to reopen the open end of the glove, e.g., to place additional waste within the glove.
In accordance with still another embodiment, a device is provided for disposing of waste that includes a glove including an open end and a plurality of finger pockets for receiving fingers of a hand inserted into the open end, the glove being sufficiently flexible to be inverted upon removal from the hand, the glove including a decorative pattern on an inside surface thereof such that the decorative pattern is exposed when the glove is inverted. Optionally, the device may include a handle adjacent the open end for carrying the device after the glove is inverted.
In accordance with yet another embodiment, a method is provided for disposing of waste that includes inserting a wearer's hand into an open end of a glove, e.g., and receiving waste material within the wearer's hand outside the glove. For example, the glove (or a pair of gloves) may be worn before performing a procedure, e.g., where it is desirable to protect the wearer's hand(s) from exposure. During or after the procedure, waste material may be grabbed while wearing the glove. The glove may be removed and at least partially inverted such that the waste material is captured within the glove, and the open end of the glove may be substantially closed with the waste material therein.
In one embodiment, closing the open end of the glove may include receiving a protrusion in a mating channel. For example, upon inverting the glove, a protrusion along the open end of the glove may be disposed adjacent but opposite to a corresponding channel. The wearer may slide his/her fingers over the protrusion and channel, e.g., from one end of the protrusion and channel to the other end, to push the protrusion into the channel. Alternatively, the open end of the glove may be closed by pulling on a drawstring disposed around the open end of the glove.
In another alternative, the open end may be closed by pulling a free end of a strap with a fixed end attached to the glove adjacent the open end and attaching the free end to the glove, e.g., opposite the fixed end. Optionally, before use, the free end of the strap may be releasably secured to the glove, for example, to an inside surface of glove, e.g., such that, when the hand is inserted into the glove, the strap may not interfere substantially with inserting the hand and/or use of the wearer's hand while wearing the glove. The free end may be released from the glove before, while, or after the glove is inverted and/or removed from the wearer's hand, and then the free end may be reattached to the glove across the open end to substantially close the open end.
In accordance with still another embodiment, a method is provided for disposing of waste that includes inserting a wearer's hand into an open end of a glove, receiving waste material within the wearer's hand outside the glove, inverting the glove such that the waste material is captured within the inverted glove to expose a decorative pattern on an inside surface of the glove. Optionally, the glove may include a handle, e.g., attached to an inside surface of the glove, that may be used to carry the inverted glove and waste material until proper disposal. The decorative pattern may conceal the glove, reduce unsightliness, or allow the user to carry the waste material inconspicuously.
Other aspects and features of the present invention will become apparent from consideration of the following description taken in conjunction with the accompanying drawings.
The drawings illustrate exemplary embodiments of the invention, in which:
Turning to the drawings,
The glove 10 may be formed from a variety of materials, e.g., elastomeric materials, such as natural rubber, nitrile or other synthetic rubber, latex, and the like. The glove 10 may be formed from one or more layers of material, e.g., to provide a desired flexibility, strength, and the like. For example, the glove 10 may be sufficiently flexible to facilitate inserting a wearer's hand therein, yet sufficiently resilient to be tight-fitting around the wearer's hand, e.g., similar to surgical or examination gloves. The wall thickness of the glove 10 may be sufficiently thin to minimize impact on the wearer's use of the hand inserted into the glove 10.
Optionally, the glove material may include other features (not shown), e.g., to facilitate inserting a hand (not shown) into the glove 10, to reduce slippage between the glove 10 and a hand inserted therein, and/or to enhance gripping objects while wearing the glove 10. For example, powder or other material (not shown) may be provided on the inside surface 22, e.g., to facilitate inserting a hand into the glove 10. Exemplary materials and methods for making a glove that may be included in the devices and methods described herein may be found, for example, in U.S. Pat. Nos. 3,852,826, 5,421,033, and 5,612,083, the entire disclosures of which are expressly incorporated by reference herein.
The closure 30 may be provided for substantially closing the open end 12, e.g., after use, as described further elsewhere herein. In the embodiment shown, the closure 30 includes a channel 32 extending along a portion of an edge 13 of the glove 10 defining the open end 12, and a hook, bead, or other protrusion 42 extending along another portion of the edge 13 generally opposite the channel 32. The protrusion 42 is generally shaped or otherwise configured to be received in the channel 32, e.g., providing a zip-lock connector.
With additional reference to
As shown, the channel 32 extends along a length of the first elongate strip 34 and is defined by a pair of spaced apart ridges 36 having complementary shapes to the protrusion 42. Similarly, the protrusion 42 extends along a length of the second elongate strip 44 and, in the embodiment shown, includes an enlarged bead 42a spaced apart from the second elongate strip 44 by a relatively narrow stem 42b. Thus, as shown in
In alternative embodiments, the protrusion, channel, and ridges may have other complementary shapes or configurations. For example, as shown in
Optionally, as shown in
Returning to
To manufacture any of the gloves described herein, one or more forms or molds (not shown) may be provided, e.g., corresponding to one or more sizes for the resulting gloves. One or more tanks (also not shown) may be provided, e.g., including one or more materials for the glove 10, e.g., liquid latex, natural rubber, nitrile rubber, chemicals for treating the form(s) or the materials applied thereto, and the like. In addition, one or more other pieces of equipment, e.g., heating or curing chambers, blowers, and the like (not shown), may be provided adjacent one or more of the tanks. The form(s) may be dipped successively into each of the tanks to apply the materials to the form(s) to provide the one or more desired layers for the glove. The materials may be cured between dipping in different materials, e.g., by heating or allowing sufficient time to cure under ambient conditions.
Optionally, powder or other materials may be applied after the materials are applied to the form(s) and/or cured. In addition or alternatively, a pattern may be applied to the form(s) after the materials are applied and/or cured. For example, one or more inks, dyes, or other pigments may be applied to the form(s), e.g., by spraying, brushing, and the like. If multiple colors are applied, the colors may be applied substantially simultaneously or successively, e.g., using multiple sprayers. The pattern may include a random pattern or may include one or more images, e.g., to provide a decorative pattern on. In exemplary embodiments, the pattern may include one or more aesthetic objects, e.g., plants, such as flowers, leaves, and the like, animals, such as cats, dogs, teddy bears, and the like, cartoon characters, people, and the like. In addition or alternatively, the pattern may include embossing features into the materials and/or building features onto the material. For example, the form(s) may include one or more recesses and/or raised regions for creating the desired features.
Upon completion, the gloves may be removed from the form(s), which may caused the gloves to invert. Thus, with reference generally to
In an exemplary embodiment, an adhesive may be applied to the bottom surfaces of the elongate strips 34, 44 and/or outside surface 20 of the glove 10 underlying the elongate strips 34, 44. The adhesive may be cured using heat, pressure, and/or ambient conditions, e.g., after sufficient time has passed. In addition or alternatively, a heat seal, sonic welded seam, and the like may be created along the edges of the elongate strips 34, 44 to attach the elongate strips 34, 44 to the outside surface 20 of the glove 10.
Optionally, ends of the elongate strips 34, 44 may be aligned with the thumb pocket and pinkie finger pocket, e.g., to facilitate orienting the elongate strips 34, 44 when the closure 30 is being used to close the open end 12. Alternatively, the ends of the elongate strips 34, 44 may be otherwise aligned opposite one another. The orientation of the elongate strips 34, 44 may bias the way that the open end 12 lies before use. However, the elongate strips 34, 44 may be sufficiently flexible, or sufficient space may be provided between the opposite ends of the elongate strips 34, 44 to allow the open end 12 to expand elastically to facilitate inserting a hand into the glove 10. Alternatively, multiple sets of elongate strips (not shown) may be applied along the open end 12, e.g., with spaces between the sets to allow expansion and/or contraction of the glove 10.
In an alternative embodiment, the elongate strips 34, 44 may be attached to the open end 12 of the glove 10 before the glove 10 is stripped from the form, e.g., using methods similar to those described further elsewhere herein. In this alternative, the glove 10 may need to be reinverted upon being removed from the form, e.g., to orient the channel 32 and protrusion 42 away from one another initially before use.
During use, one or two gloves, similar to glove 10, may be worn by a wearer. For example, the wearer may be a consumer, e.g., a parent or other care provider for an infant or other person wearing a diaper. For example, a parent or other care provider may don a glove 10 before changing the diaper of an infant or other person. After changing the diaper, the wearer may simply grab the diaper (not shown) in their palm, and pull the glove 10 off, thereby capturing the diaper and any other desired materials, such as wipes or cloths, within the glove 10. The closure 30 may then used to substantially close the open end 12, thereby capturing the diaper and other materials within the glove 10.
In other applications, a health care provider may wear the glove 10 (or a pair of gloves, not shown) before treating a patient. Upon completing an examination or treatment, which may involve contacting the patient with gauze or other materials, e.g., to pick up blood or other bodily fluids, deliver fluids or other materials that may contaminating, corrosive, toxic, and the like, any material used by the wearer may be captured within the glove 10 simply by grabbing the material before removing the glove 10. The open end 12 of the glove 10 may then be closed to prevent the material from falling out of the glove 10 or being accidentally exposed before proper disposal. Optionally, the glove 10 may be used without receiving any waste objects therein, e.g., if it is desired to contain fluids or other materials to which the glove 10 was exposed.

Optionally, as shown in
In an alternative embodiment, other handle configurations may be provided (not shown). For example, the handle may include an enclosed loop (not shown), and a strap or other feature (also not shown) may extend from the loop that is attached to the glove 210. Optionally, the loop may be releasably secured to the glove 210, e.g., to the outside surface 220 or inside surface 222.
In addition, as best seen in
The decorative pattern 223 may conceal or obscure the contents of the glove 210 or may provide a desired aesthetic appearance to reduce embarrassment until the glove 210 can be disposed of. For example, a parent may don a glove 210 before changing a diaper of their infant. After changing the diaper, the parent may simply grab the diaper (not shown) in their palm, and pull the glove 210 off, thereby capturing the diaper and any other materials within the glove 210. In such an application, the pattern may include baby themes or other desired features, such as those described elsewhere herein.
Turning to
To make the glove 310, the glove 310 may be formed using any of the methods described elsewhere herein, although a flap (not shown) may be provided on the open end 312. The flap may be rolled and attached to the open end 312, e.g., by bonding with adhesive, sonic welding, heat sealing, and the like, to provide the pocket 334. The drawstring 332 may be directed through the pocket 334 before or after attaching the flap. Alternatively, the edge of the open end 312 may simply be rolled and attached, and the pair of openings 336 may be created through the pocket material, e.g., by punching, mechanical or laser cutting, and the like. The ends 333 of the drawstring 332 may be attached to one another, e.g., by tying one or more knots.
During use, the glove 310 may be used by a wearer similar to other embodiments herein. After use, waste material may be grabbed, and the glove 310 may be removed to capture the material within the glove 310 as the glove 310 is inverted. The ends 333 of the drawstring 332 may be pulled to tighten the drawstring 332 and close the open end 312. Optionally, the drawstring 332 may include a lock that may be applied to the drawstring 332 to prevent the open end 312 from accidentally reopening. For example, a slide lock 338 may be provided on the drawings 332 that may be slid down the ends 333 until the slide lock 338 abuts the glove 310. The drawstring 332 may also be used as a handle, if desired. Alternatively, the ends 333 of the drawstring 332 may simply be tied, e.g., knotting down onto the glove 310 to prevent the open end 312 from reopening.
Turning to
Optionally, the second end 436 of the strap 432 may be releasably secured to the glove 410, e.g., similar to the handle 350 described above. For example, as shown, the second end 436 may be secured to the first end 434 of the strap 434 or elsewhere to the inside surface 422 of the glove 410, e.g., adjacent the open end 412. The second end 436 may be attached using a low tack adhesive, e.g., which may have sufficient tack to secure the second end 436 over the first end 434 or elsewhere to the inside surface 422 before and during use. For example, the second end 436 of the strap 434 may be secured initially such that the strap 432 is taut or not slack, e.g., such that the strap 432 does not interference substantially with a wearer inserting their hand into the open end 412 of the glove 410. Optionally, the exposed surface of the second end 436 may include an adhesive, e.g., initially covered with release paper, which may be used to attach the second end 436 to the glove 410 after use, as described further below.
Alternatively, the second end 436 may be releasably secured to the glove 410 using a hook and eye connection, e.g., if the second end 436 includes a hook and eye fastener (not shown). A mating hook and eye fastener (not shown) may be provided on the exposed surface of the first end 434 or elsewhere on the inside surface 422. In this alternative, another mating hook and eye fastener may be provided on the inside surface 422 of the glove 410, e.g., generally opposite the first end 434 of the strap 432. For example, as shown in
Optionally, the strap 432 may be formed from elastic material, e.g., an elastomeric material, such as latex, natural rubber, synthetic rubber, and the like. Thus, the strap 432 may be stretchable, e.g., when the second end 436 is pulled away from the first end 434. Alternatively, the strap 432 may be formed from inelastic material, but may have sufficient length to allow the second end 436 to be attached to the glove 410 after use, as described further below.
During use, the glove 410 may be worn by a wearer, similar to the other embodiments described herein. Before or after removing the glove 410, the second end 436 of the strap 432 may be separated from the glove 410 and pulled across the open end 412, as shown in
Optionally, if the strap 432 is inelastic or has sufficient length, the strap 432 may provide a handle when the second end 436 is attached to the glove 410, which may facilitate carrying the glove 410 and any waste material therein until disposed of.
It will be appreciated that elements or components shown with any embodiment herein are exemplary for the specific embodiment and may be used on or in combination with other embodiments disclosed herein.
While the invention is susceptible to various modifications, and alternative forms, specific examples thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that the invention is not to be limited to the particular forms or methods disclosed, but to the contrary, the invention is to cover all modifications, equivalents and alternatives falling within the scope of the appended claims.
