Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
A glove (10), as shown in
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
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
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.
The film may be a monolayer or a multilayer film, and comprises one or more styrenic block copolymers (SBCs), olefinic block copolymers (OBCs), or combinations thereof.

Any apparatus suitable for making an elastomeric film as described herein may be used, and would be readily understood by one of skill in the art. One example of an apparatus suitable for making the films is described in, e.g., U.S. Pat. No. 9,492,332 (Cancio et al.) and U.S. Pat. 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
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
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. The method comprises the step of placing the glove on a hand of a user, wherein friction between the glove and the hand is reduced when placing the glove on the hand. The glove according to this method can be formed from any of the preactivated elastomeric film embodiments according to the present disclosure.

All documents cited in the Detailed Description of the Invention are, in relevant part, incorporated herein by reference; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention. To the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern. All ranges are inclusive and combinable. To the extent a value is not explicitly listed, it is understood to be implied as an option if included in a recited range.
Whereas particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the present claims all such changes and modifications that are within the scope of this invention.
The following numbered clauses include embodiments that are contemplated and non-limiting:
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.
In certain embodiments, the gloves and/or films of the present disclosure can be analyzed for tensile, structure, and puncture as shown in Table 2.
