Puncture indicating gloves

Abstract

A puncture indicating glove comprises a bilayer formed by an inner glove layer and an outer glove layer, the outer glove having an opacity in the range of 23-34%. The opacity of the over glove is controlled by the inclusion in the over glove of a fine particulate material, in particular selected from the group comprising titanium dioxide, silica, barite powder, barium sulphate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, basic magnesium carbonate, zinc oxide. The inner glove has a chroma range C* which is controlled to result in a glove that indicates optimally with transparent liquid and strongly coloured liquids such as blood. The inner glove has a chroma C* which is greater than 30, advantageously greater than 40, more preferably greater than 43, and in particular greater than 46.

1 . A puncture indicating glove comprising a bilayer formed by an inner glove layer and an outer glove layer, the outer glove having an opacity in the range of 15-40%. 
   
   
       2 . A puncture indicating glove according to  claim 1 , wherein the opacity is in the range of 18 to 38% , advantageously 20 to 35% and more particularly 23 to 34%. 
   
   
       3 . A puncture indicating glove according to  claim 1 , wherein the opacity of the over glove is controlled by the inclusion in the over glove of a fine particulate material, in particular selected from the group comprising titanium dioxide, silica, barite powder, barium sulphate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, basic magnesium carbonate, zinc oxide. 
   
   
       4 . A puncture indicating glove according to  claim 1 , wherein the inner glove has a chroma range C* which is controlled to result in a glove that indicates optimally with transparent liquid and strongly coloured liquids such as blood. 
   
   
       5 . A puncture indicating glove according to  claim 1 , wherein the inner glove has a chroma C* which is greater than 30, advantageously greater than 40, more preferably greater than 43, and in particular greater than 46. 
   
   
       6 . A puncture indicating glove according to  claim 4 , wherein the inner glove includes pigment in order to control the chroma. 
   
   
       7 . A puncture indicating glove according to  claim 6 , wherein the chroma is varied by choosing pigments of relatively high values of C* and/or increasing the amount of said pigment. 
   
   
       8 . A puncture indicating glove according to  claim 1 , wherein L* of the inner glove is less than 45, preferably less than 35 and more preferably less than 32. 
   
   
       9 . A puncture indicating glove according to  claim 1 , wherein the product of C* and 1/L* is greater than 0.8, more preferably greater than 1.2 and in particular greater than 1.5. 
   
   
       10 . A puncture indicating glove according to  claim 1 , wherein the inner glove is of a colour having a hue angle in the range of 160-300°, advantageously 180-280°, more preferably 220-270° and in particular 250-270°. 
   
   
       11 . A puncture indicating glove according to  claim 1 , wherein the inner glove has a colour that contrasts with red. 
   
   
       12 . A puncture indicating glove according to  claim 1 , wherein a middle layer is disposed between the inner and outer layers, which middle layer has a refractive index which varies depending on its liquid content. 
   
   
       13 . A puncture indicating glove according to  claim 12 , wherein the opacity of the material of the middle layer decreases in the presence of liquid, thereby increasing the visibility of the inner layer when liquid is present. 
   
   
       14 . A puncture indicating glove according to  claim 1 , wherein the outer glove includes finely milled organic or inorganic pigments.
