Definitions

  • the present invention relates to a glove and a method of making a glove.
  • the invention relates to a glove with improved antimicrobial properties.
  • Disposable gloves such as latex gloves or gloves from a pair of plastic films which are heat sealed together forming a rough glove shape are well known in the art. These are particularly used to protect a user’s hands, particularly to prevent the spread of infectious agents to and from the hands. These are used in many fields where there is a desire to restrict the spread of infectious agents. Such gloves are effective as a barrier for preventing the spread of infectious agents either to or from the hands. However, if a user wearing the gloves has touched an infectious agent, generally the gloves cannot stop this being spread to other surfaces which are subsequently touched by the user. Indeed, the gloves may be counterproductive in such a situation as they create a false sense of security for the wearer and hence reduced awareness that they may be transmitting infectious agents from surface to surface.
  • the glove has a foam layer which is impregnated with an alcohol.
  • the glove fulfils a different purpose from the Sani Glove.
  • the present invention provides a glove which is specifically designed to prevent the wearer of the gloves from transferring infectious agent from one surface to another. This is achieved because the glove of the present invention retains the alcohol in a foam and is therefore able to retain the antimicrobial agent for much longer. In particular, if the wearer has touched an infectious agent such as a microorganism, this will be killed by the alcohol. Further, the wearer will leave small deposits of alcohol on the surfaces that they touch.
  • the alcohol may be present in liquid form, bit is preferably a gel as this will be more readily retained in the foam and will not evaporate as quickly.
  • alcohol gel refers to a mixture containing isopropyl alcohol or alcohol or ethanol or methanol, which is used to assist in killing microrganisms.
  • the present invention therefore not only provides a barrier to infectious agents being transmitted to and from the user’s hands, but also improves the surrounding environment by killing infectious agents that are touched by the user as well as leaving deposits of alcohol on surfaces which are likely to be touched by other users such as doorknobs and the like.
  • the term ‘glove’ also covers a ‘mitten’.
  • the alcohol may be applied as part of the manufacturing process.
  • the gloves may be made without the alcohol and this can be applied just before or while they are worn. More alcohol can also be applied to the glove in the event that the alcohol has been depleted.
  • the first layer is impermeable to the alcohol at least in the parts of the first layer which are covered by the foam layer.
  • the whole of the first layer may be impermeable to alcohol.
  • only parts of the glove may be impermeable to alcohol while other parts of the glove may be made of a different material, for example a more permeable material which allows the glove to ‘breath’.
  • first layer may be impermeable to the alcohol on one side of the glove, allowing the glove to have a more permeable back.
  • the foam layer may extend across a relatively small part of the one side of the glove. For example can only be provided at the fingertips which are the portion of the glove most likely to come into contact with other surfaces. Flowever, preferably, the foam layer extends across more than half of the first layer on one side of the glove. More preferably, the foam layer extends across all of the parts of the first layer on at least one side of the part of the glove which, in use, covers the user’s hand. More preferably, the foam layer covers the whole surface of the first layer on at least one side of the glove.
  • the foam layer does not extend beyond the first layer.
  • the purpose of the foam layer is to protect any surfaces touched by the gloves.
  • the wipe In the Sani Glove, the wipe extends a long way beyond the glove. This is because it is intended to be worn just to clean/disinfect a specific object or surface. Our glove is intended to be worn for longer and to provide protection to a user and the surroundings in a general sense.
  • the foam layer may be provided only on one side of the glove. Alternatively the foam layer is provided on both sides of the glove. This allows an individual glove to be worn on either hand, and provides protection to the back of the hand, which will not contact surfaces as regularly as the palm side of the hand, but still has the capability of spreading infectious agents between surfaces. Also, if the alcohol gel on the palm side has been depleted by repeated touching of surfaces by the palm side of the hand, the gloves can be reversed as there is likely to be more gel retained on the other side of the glove.
  • the foam layer is provided on both sides of the glove, this preferably extends to the extent described above in relation to the foam layer on one side of the glove.
  • the first layer may be a formed latex, rubber, cloth, leather layer. However, if the first layer is formed of a material which is not impermeable to the alcohol, it may be coated with an impermeable layer.
  • the first layer may, for example be provided by a pair of plastic films which may be biodegradable plastic films which are heat sealed around their peripheral edge.
  • the foam layer is preferably a layer of foam open cell foam which may be sponge.
  • the glove preferably further comprises a layer of alcohol permeable material covering the foam layer.
  • This layer maybe made from a material which has antimicrobial properties.
  • the glove preferably comprises a layer of alcohol permeable material on the side of the first layer opposite to the foam.
  • Such a glove may be washable and reusable rather than disposable.
  • the back side of the glove is preferably formed as a layer of an alcohol permeable material. This layer maybe made from a material which has antimicrobial properties.
  • the glove preferably, further comprises a slit in at least one finger or thumb region to allow a finger or thumb to pass through the glove.
  • the glove may further comprise an electrically conductive track in at least one fingertip region of the glove.
  • the present invention also extends to a sealed pack containing one or more gloves according to the first aspect of the invention.
  • the web of two layers is preferably provided from a tube of flexible material which is flattened.
  • the foam may be attached to the first layer using an adhesive.
  • the foam may be heated until it is molten and the foam material may be fused to the material of the first layer.
  • the method comprises adhering the foam layer to one or both sides of the glove-shaped regions.
  • the foam second layer may be soaked in alcohol gel before or after the gloves have been cut from a film. However, preferably, this is done before the cutting stage as the location of the gloves can be better controlled at this stage.
  • two sides of the glove may be stitched together and a thumb part may be stitched in place to form the finished glove.
  • the foam layer may be added either before or after the parts are stitched together. This allows a higher quality and more fitted glove to be produced.
  • the gel may be applied by spraying or coating using a blade, or by dipping the web in a reservoir of gel.
  • the method preferably further comprises placing one or more gloves in a plastic bag and sealing the plastic bag.
  • the alcohol may be applied as part of the manufacturing process.
  • the gloves may be made without the alcohol and this can be applied just before or while they are worn

  • the glove 1 is formed of a pair of flexible plastic sheet layers 2 which are heat sealed at their periphery 3 in order to form the closed glove structure open at the wrist.
  • a layer of foam 4 is bonded to each face to each of the flexible plastic sheets 2 and is impregnated with an alcohol gel.
  • the alcohol could be isopropyl alcohol, or ethanol or methanol
  • the foam 4 preferably covers the entirety of both sides of the glove. However, it may be absent in certain regions, for example in the vicinity of the wrist portion of the glove.
  • a first method of manufacture of the glove is shown in Figure 3.
  • a first drum 10 has a web 11 of a flattened blown tubular material which provides the film layers 2 shown in Fig 1. This passes through a heat sealing station 12 with a number of heating element having a shape corresponding to the outline of the glove 1 shown in Fig 1. The two webs 2 are sealed together at the periphery 3 whilst still remaining attached to the web.
  • the glove may be made in a batch process using sheets of the materials that are stamped rather than being done as a web based method as described above.
