    •  DETAILED DESCRIPTION
  • A glove (10), as shown in FIGS. 1-3 , includes a cuff (12), a finger receiver (14), and a glove body (16) that cooperate to retain the glove on a user's hand and provide a barrier between a user's hand and an exterior environment. As described herein, the gloves of the present disclosure provide improved functionality for the user. For instance, the gloves of the present disclosure may have improved feel, tackiness, and/or elasticity while at the same time be easier for donning by the user.
  • The glove of the present disclosure may be formed from a preactivated elastomeric film that includes activation stripes, which may result from deformation of the film during the preactivation process. Viewed laterally, the activation stripes may impart a wavy appearance to the film, wherein the waves have ridges and furrows and thus form channels in the glove. The channels formed by the activation stripes may extend from glove body (10) to finger receiver (14), as shown in FIG. 1 , and may be visibly apparent on both an outer-surface of glove and an inner surface of glove.
  • Activation stripes may allow air to circulate within the glove thus providing additional comfort when worn by a user. Activation stripes further may reduce friction when a user dons the glove, thus reducing or eliminating the need for a lubricating substance. Accordingly, in one embodiment, the glove is substantially free of a lubricating substance, understood herein to mean any substance that allows a user's hand to be more easily inserted into the glove, non-limiting examples being a powder, such as a mineral-based powder (for example, talc), a silicone-based coating, or a moisturizer. As used herein, the term “substantially free” refers to zero or nearly no detectable amount of a material, quantity, or item. For example, the amount can be less than 2 percent, less than 0.5 percent, or less than 0.1 percent of the material, quantity, or item. In some embodiments, the glove does not comprise a lubricating substance.
  • The glove of the present disclosure may be formed from a preactivated elastomeric film that includes embossing, which results in an embossed film. As used herein, “embossed” refers to a film in which a portion of the surface stands out in relief from the surrounding film surface. The films of the present disclosure may comprise designs or patterns that in turn comprise a plurality of embossing depths, widths and spacing between adjacent design elements.
  • Exemplary embodiments of films with various embossing patterns are shown in FIG. 6 . Embossed films may provide friction reduction of the glove. In some embodiments, the glove of the present disclosure may be formed from a preactivated elastomeric film that includes both activation stripes and embossing.
  • In other embodiments, the glove may include a lubricating substance on the interior surface to further improve donning and comfort.
  • In illustrative embodiments, the film is breathable, meaning that the film is impermeable to liquids, and yet permeable to water vapor. Water vapor transmission rate (“WVTR”) is a measure of film breathability. WVTR is expressed in units of g H2O/24 hours/m2 or equivalent units thereof, and may be measured according to ASTM method D-6701-01. In some embodiments, the film may have a WVTR of at least 500 grams H2O/24-hour/m2, alternatively at least 1,000 grams H2O/24-hour/m2, alternatively at least 2,000 grams H2O/24-hour/m2 alternatively at least 3500 grams H2O/24-hour/m2, alternatively of at least 4500 grams H2O/24-hour/m2, alternatively of at least about 6,000 grams H2O/24-hour/m2, alternatively of at least about 7,000 grams H2O/24-hour/m2, alternatively of at least about 9,000 grams H2O/24-hour/m2, and alternatively of from about 1,000 grams H2O/24-hour/m2 to about 10,000 grams H2O/24-hour/m2.

No. 7,442,332 (Cancio et al.), incorporated in relevant part herein. Methods described generally therein also are suitable for producing the films, with the exception of differences noted herein which contribute to the unique properties of the presently claimed films.
  • In some embodiments, the films may be coextruded, and may be cast, blown, or formed by any other method that would result in the films described herein.
  • “Preactivation,” as used herein, means that a film is stretched prior to being formed into the glove. Preactivation may occur as a separate step in the manufacturing process or in-line with the formation of the glove. A preactivated film may undergo additional stretching steps prior to being formed into the glove.
  • Preactivation may occur by a variety of means that would be known to one of skill in the art, and the film may be preactivated in one or both of the cross-direction or the machine-direction. The film may, for example, be preactivated by stretching the film by at least 50% and subsequently allowing the film to relax. One particularly suitable means of preactivation is via cross-directional or machine-directional intermeshing. Cross-directional intermeshing, or CDI, is described, e.g., in U.S. Pat. No. 5,861,074 (Wu, et al., incorporated herein by reference). The depth of intermeshing may vary from about 0.01 inches to about 0.250 inches, and in particular embodiments may be 0.120 inches, 0.140 inches, 0.160 inches or 0.180 inches. After a film is subjected to CDI, activation stripes are visible on both sides of the film.
  • The glove of the present disclosure has a snug, comfortable fit. Due to their elastic nature and the ease of donning the gloves, the gloves of the present disclosure are made to be more form-fitting. In illustrative embodiments, the gloves of the present disclosure fit more comfortably around the hand of the user. For example, Table 1 shows a comparison of finger widths between a prior art poly glove and a glove of the present disclosure. As shown in Table 1 and also in FIG. 7 , the gloves of the present disclosure have a reduced finger width in order to advantageously be more form-fitting.

  • In some embodiments, the snug, comfortable fit of the glove correlates to the permanent set of the film, understood herein to mean the permanent deformation of a material after removal of an applied load. The lower the permanent set, the more snug the fit. The films herein may have a permanent set of less than about 20%, alternatively less than about 10%, and alternatively less than about 5%. In elastomeric films, the permanent set is the increase in length of a sample of a film after the film has been stretched to a given length and then allowed to relax. Permanent set is typically expressed as a percent increase relative to the original size. By way of example only, if a 10 cm piece of elastomeric film is stretched to 20 cm, then allowed to relax, and the resulting relaxed film is 12.0 cm in length, the permanent set of the film is 20%.
  • The test method used to measure permanent set is based upon ASTM D882-97 with the following details. The sample is cut to make one inch by six inch specimens—the six inch length is in the direction the of the film or laminate is being tested (e.g., in the CD direction for the examples below). An MTS Tensile Tester (Qtest) is used to measure the sample deformation. The tester grip faces are rubber grip faces that are 25 mm wide (MTS part No. 56163829). The sample is loaded with a grip distance set at two inches from the center of upper grip face to the center of the lower grip face. The strain endpoint is set to 100%. The first upload cycle is run at a rate of 20 inches/minute to the strain endpoint, then immediately returns to 0% strain at a rate of 20 inches/minute, and then is held at 0% strain for 30 seconds. The second upload cycle is run at a rate of 20 inches/minute to the strain endpoint, and then immediately returns to 0% strain at a rate of 20 inches/minute. The permanent set is calculated at the point when load reaches eight grams of force during the second upload cycle.
  • In some embodiments, the glove may be substantially comprised of preactivated film. In other embodiments, portions of the glove may comprise unpreactivated film. In one embodiment, the body (16) of the glove (10) may comprise discreet and customizable areas comprising preactivated (18) and unpreactivated film (20), as depicted in FIG. 5 . In yet another embodiment, the fingertips of the glove may comprise unpreactivated film, which may serve to improve the user's grip or sensitivity at the fingertips. It is understood that other embodiments may comprise certain areas in which the glove comprises unpreactivated film.
  • FIG. 4 depicts a schematic representation of one suitable process for manufacturing the gloves, comprising the steps of forming the film (110), preactivating the film (120), forming a die (130), and forming the glove (140). The gloves of the present invention may be produced by the cutting and sealing method, described, e.g., in U.S. Pat. No. 3,335,281 (Chisolm) and U.S. Patent Application Publication No. 2015/0047097A1 (Tao), incorporated in relevant part herein by reference. In one method of making the glove, two sheets of a pre-activated film are laid atop one another and brought into contact with die which may be shaped in the form of a human hand, and which optionally may be temperature-controlled. A non-stick layer may be applied between the die and the sheet of film in contact with the die. The two sheets of film are sealed to form the body of the glove, and one portion of the glove, the cuff, is left unsealed to insert the hand. The glove is then cut from the sheets of film along the seal.
  • The die may be sharpened to form a hand-shaped knife. Hand-shaped knives of varying sizes may be used to produce gloves having a snug fit for various sized hands. Cutting may occur by a variety of means that would be known to one of skill in the art, such as applying pressure to a sharp edge of the die, or alternatively by means of a laser.
  • In an alternative method of making, a sheet of film may be brought into contact with two separate dies, each having the shape of a human hand, and one die being a mirror image of the other. The film is cut in the shape of the die to produce a first and a second portion of film having the shape of a human hand. The first portion of film is laid atop the second portion of film, such that the shapes of the finger receivers and the body of the glove are aligned. The edges of the two portions of film may then be sealed, leaving the cuff portion unsealed, to form a glove.
  • Other methods of assembling the gloves described herein would be apparent to one of skill in the art.
  • The gloves are suitable for a variety of purposes in which maintain hand hygiene is desirable, including during medical and first-aid procedures and food preparation.
  • In an illustrative embodiment, a method of minimizing friction upon donning a glove is provided.

    EXAMPLES Example 1: Exemplary Embossing Procedure
  • In certain embodiments, the films of the present disclosure can be embossed. Without being bound by any theory, it is believed that embossing film breaks up the surface of the film and creates a multi-level or broken surface, thus reducing the friction between the film and another surface by reducing the area of film touching the surface when compared to a non-embossed film with a smooth surface. As applicable to the present disclosure, an embossed film used to make it easier for a user to put on the gloves.
  • In an exemplary process, film can be extruded and run between two rolls, one roll having a softer coated finish, and a second roll that has the textured pattern machined into the surface. By applying pressure, the pattern from the embossed roll can be imparted to the film as it runs between the rolls.
  • A textured roll can also be used with extruded/cast film and laid onto the textured roller without having the second roller applying pressure to the film/textured roll. This can result in some texture that is applied to the film. Alternatively, it may be advantageous to not apply pressure.
