A common problem in the use of hygienic gloves is donning a glove without contaminating it. Donning a glove can result in the glove becoming contaminated through contact with either of the users' hands. Ideally, users should don gloves with minimal, if any, contact with the outer surface of the glove to be used or with any other gloves contained in the packaging. An additional problem in the use of hygienic gloves is the lack of a mechanism or device to rapidly and easily don the glove using only a single hand.
The prior art solutions have focused on helping the user avoid contact with the rest of the glove while donning. However, these solutions do not allow for the single-handed donning of multiple gloves by multiple users in repeat succession, with minimal set up and while simultaneously avoiding contact with the outer surface of the glove. This problem has not been adequately addressed by others in the art.
The objects of the invention include one or more of the following:
The present invention provides an apparatus and method for donning hygienic gloves that allows the user to quickly and with minimal effort, don both right and left gloves, one-handed, while minimizing the possibility of contamination. It also provides a low cost hygienic glove dispensing and donning apparatus that would have practical application in both the medical and food service industries as well as in general use.
The apparatus of the invention for donning hygienic gloves comprises a plurality of glove sheets bound together in a stack, a box or package containing the stack of glove sheets, and a dispenser for removably holding the box such that the box of gloves can be replaced when empty. Each glove sheet comprises a top layer and a bottom layer, the bottom layer being longer on a proximal side than the top layer thereby forming a tail. Each glove sheet comprises a bi-layered glove and a remnant portion, the glove being frangibly connected to the remnant portion, such that the glove can be easily torn away from the remnant portion by the user when donning a glove. The top and bottom layers of each sheet are sealed together in a hand-shaped seam to form the glove, the glove having a cuff and a hand opening therein on the proximal side of the glove sheet.
The box containing the stack of glove sheets protects the gloves from contamination. The box may include posts or other fasteners for securing the remnant portions of the glove sheets together. The sheets are also bonded or heat-sealed together within the remnant portion. In a preferred embodiment, the sheets include strategically positioned sealing points in the remnant portion of each sheet. The sealing points together maintain the integrity of the stack and facilitate clean separation from the remnant and removal from the stack.
The box includes a detachable flap aligned substantially with the glove portion of the glove sheets such that removal of the flap exposes a top one of the glove sheets. The detachable flap preferably has the overall configuration of a glove. More specifically, the detachable flap has a glove outline that corresponds to the gloves within the stack such that the remnant portions of the glove sheet are substantially covered by a portion of the front panel of the box that remains after the flap is detached.
The dispenser holds the box, the box being removable from the dispenser. The dispenser includes an opening on a front face configured to be substantially aligned with the detachable flap of the box. In the preferred embodiment, the peripheral margins of the opening in the dispenser matches and aligns with the outline of the removeable flap, which also matches and aligns with the outline of the gloves. A back panel of the dispenser preferably includes a wall mount, whereby the dispenser can be vertically mounted on a wall, preferably 4-5 feet above the floor. The dispenser may optionally be placed or mounted horizontally or may be mounted at an angle. A user dons a glove by extending and sliding his/her fingers over the tail portion of the bottom layer, under the top layer and into the hand opening. A simple inward and upward motion causes the glove to tear away from the remnant. Accordingly, the glove can be donned quickly and easily using only one hand, without making any contact with the exterior surface of the glove and without contacting the other gloves in the package. A single dispenser and stack can be used for either the right or left hand with a pronation and supination movement. However, a pair of dispensers can be provided for right and left gloves. In one embodiment, a single dispenser is provided with a one-size-fits-all glove. Other embodiments may include multiple dispensers with different size gloves. Preferably, the gloves sheets are stretchable polyethylene film. The box or package can be a plastic box or even a poly wrappers, but preferably is a cardboard box. In one embodiment, the box is a plastic wrapped cardboard box—the plastic wrap being removable before the box is inserted into the dispenser. The term “box” as used herein means any sort of box, bag or package the encloses and contains the stack of glove sheets. The dispenser can be made of any substantially rigid and durable material, such as molded plastic, aluminum or other metals. More preferred materials include one-piece molded acrylic and stainless steel.
The invention further includes a method of donning hygienic gloves that comprises the steps of providing a dispenser having a hand-shaped opening on a front panel and a box of gloves, the box having a hand-shaped detachable flap on a front panel, installing the box of gloves in the dispenser, and removing the flap from the front and bottom side of the box to expose an upper one of a stack of glove sheets in substantially hygienic condition. A person can easily don a glove by extending and sliding his/her fingers over a tail portion of a bottom layer of the glove, under a top layer and into a hand opening. A simple inward and upward motion causes the glove to fully don and tear away from the remnant portion and the other glove sheets in the stack. The method preferably includes a step of separating the top layer of the next glove from its bottom layer as the previous glove is torn away.
Further objects and advantages of the invention will be apparent from the drawings and the following detailed description of preferred embodiments.

As shown in
The layers 26 and 28 which comprise the glove sheet can be formed from plastic film fed off rolls. The glove is formed by heat-sealing the two layers 26 and 28 forming a seam 38 in the shape of a hand. The plastic film is preferably stretchable polyethylene or alternative materials, such as conventional polyethylene film, other polymers such as polyvinyl. A preferred embodiment is one size fits all (“OSFA”) without a right/left orientation, but gloves could be offered in various sizes and/or in separate right and left configurations. Antimicrobial additives and/or lubricating substances to aid in donning could be applied between the top and bottom sheets.
Alternatively, to the above, the gloves could be made from a material like nitrile or latex rather than polyethylene film. In this embodiment, the gloves may not be made from two “welded” layers, but rather by a conventional dipping process. In that case, the gloves would be removably attached to the substrate remnant.
Although not required, an optional means may be provided to separate the top and bottom glove layers to aid in the donning of gloves. As schematically shown in
As the glove sheets 14 are cut from the roll (after glove forming), they are stacked and packaged one on top of another with the glove portions being aligned. Packaging is such that the form of the sheet (and stack of sheets 24) is maintained as flat and with edges aligned evenly and in sufficient number, e.g., 50 sheet per stack, to be determined to completely fill one box or package 16. The stack of glove sheets 24 are bundled, stabilized and/or secured together. The stack of gloves may be bonded or glued or otherwise fixed together, in the remnant portion, to aid in this stabilization.
Referring to
Front template 45 is sized so that the outer periphery fits snugly within the box, and includes a central opening for removal of gloves. The opening is preferably hand-shaped to match and align with the seam 38. The front template guides the user where to insert their hand to don a glove, helps hold the remnant portions while a glove is being removed, and aids in the clean tear-away of the glove from the remnant and stack.
In an alternative embodiment, the posts 40 are mounted on the dispenser 18 as discussed below and the package 16 and glove sheets 14 are provided with corresponding holes 42. In yet another alternate embodiment the posts extend through the back panel and/or front panel of the package with or without additional back or front templates.
The posts 40 and templates 44 and 45 can be fabricated from any suitable material. The posts can be plastic, metal or wood. The templates can be plastic, cork, cardboard, metal or wood. Preferably the posts 40 and templates 44 and 45 are molded plastic. The posts 40 and front template 45 assure that when a user pulls away, glove 12 cleanly separates, the remnant 22 stays behind in the box 16, and the remaining glove sheets 14 are not dislodged or twisted, i.e., the integrity of the stack 24 is secured.
There are numerous alternative means by which the stack of glove sheets can be bundled, stabilized and/or secured within box 16. Preferably the sheets within the sack are heat-sealed together at certain points within the remnant portion to maintain the integrity and shape of the stack as gloves are donned. In an alternative embodiment, the remnant portions 22 of successive glove sheets 14 can be secured together by adhesive, friction welding, rivets, pins, ribbons, other fasteners, or simply under pressure provided in the packaging. In yet another alternative embodiment each glove sheet 14 can be attached on their peripheral edges to other sheets in the stack, and/or to the interior sides of the package or box 16. These and other bundling means will be apparent to those skilled in the art and may involve a combination of one or more of these methods.
The dispenser 18 can be constructed of sturdy but thin material, either plastic, such as molded acrylic, or metal, such as aluminum or stainless steel. One embodiment of the dispenser 18 comprises a front portion 48 and a rear portion 50 which are attached at the proximal end by a hinge 52. A wall mount 54 is attached to a rear portion 50 of the dispenser. In this configuration, the dispenser 18 can be vertically mounted to a wall, preferably 4-5 feet above the floor. Alternatively, the dispenser can rest flat on a surface such as a desk or counter. When a box 16 of gloves 12 is exhausted, the front portion 48 can be pivoted away from the wall mounted rear portion 50. The empty box can then be removed, a fresh box inserted, and the front portion 48 closed again.
Alternatively, as shown in
The dispenser 18 has an opening 56 corresponding generally to but slightly larger than the removable flap 20 of the box. Despite the opening, the dispenser has sufficient structure in front of the dispenser 18 at the perimeter and overlying the remnant portion of the gloves, to firmly secure the box 16 in place. Thereby, a box 16 can be installed opened or unopened in the dispenser 18 and then the flap 20 removed either before or more preferably after installation. Removing the flap after installation in the dispenser reduces the risk of contamination and helps maintain the hygienic condition of the gloves. In the wall-mounted, vertical orientation, at approximately 4-5 feet height, the opened package 16 present gloves 12 which can be easily donned by either hand by after using a lateral rotation of the hand (pronation or supination) to align with the glove, sliding the hand up between the two layers 26, 28 of one glove 12 and pulling (tearing) the glove 12 away from the stack 24 and dispenser 18.
In an alternate embodiment, posts 40 can be molded with or mounted to the rear panel of the dispenser rather than be part of the packaging process. In this embodiment, the package 16 and sheets 14 are provided with mating through holes 42. Accordingly, the package 16 is inserted onto the posts 40 that extend through the package 16 and the stack 24 of glove sheets 14, and thereby stabilize the glove sheets 14. The advantage of this alternative embodiment is that posts 40 are reused rather than thrown away with each empty package 16, thereby reducing costs.
An alternative embodiment of a glove sheet 60 is shown in
The term “substantially matches and aligns” as applied to flap 20 means that the configuration of perforation line 46 of the glove portion of the flap approximates or is slightly larger than the configuration of the glove seam 38 such that gloves can be extracted freely and without damage, while the remnant portions are restrained. Likewise, the term “substantially matches and aligns” as applied to the glove portion of opening 56 means that the peripheral margin of the glove portion of the opening 56 approximates or is slightly larger than the configuration of flap perforation line 46 and seam 38 such that the flap 20 can be removed after the box is installed in the dispenser, and the gloves can be extracted freely and without damage, while the remnant portions are restrained.
There are many and varied uses for the glove donning apparatus 10 and method of the invention, including the healthcare and food service industries. Specific applications in healthcare may include nurse's station, patient rooms, daycare centers and nursing homes. Food service applications include meal preparation at cafeterias, restaurants, fast food, and catering. Other applications include gas stations, factories and corporate settings or any other application where reducing the transmission of contaminants and infective agents is desired. The glove donning apparatus of the invention also has domestic applications such as household cleaning, infant care, pet bathing, food preparation, painting and garbage removal.
Since modifications within the spirit and scope of the invention may readily be effected by persons skilled within the art, it is to be understood that this invention is not limited to the particular embodiments described by way of example hereinabove. In the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
