Glove with integrally formed arm trough for capturing liquids and a method therefor
A glove with an integrally formed arm trough has a hand portion, arm portion and a cuff portion. The arm portion is provided with a first ridge, a second ridge with a larger diameter compared to the arm portion, and a third ridge. During use, the third ridge is pushed towards the first ridge by the user to extend the second ridge away from the arm and towards the hand portion forming a liquid capturing trough while the cuff portion protects from the arm from liquid exposure. The length between the third ridge and the second ridge is larger than the length between the first and second ridge so that the trough created has a positive cone angle and a depth to sufficient to provide liquid volume capacity. The ridges are shaped as sharp edges or C-sections to provide easy forming of the liquid capturing arm trough.
1. An elastomeric article, comprising:
an integral latex glove comprising a hand portion, an arm portion and a cuff portion;
the arm portion comprising a first ridge, a second ridge, and a third ridge;
the second ridge having a larger diameter as compared to a diameter of the arm portion;
a first distance between the second ridge and the third ridge being greater than a second distance between the first ridge and the second ridge;
a trough comprising two layers being formed during use of the glove when the third ridge is displaced towards the first ridge thereby resulting in a projection of the second ridge away from the arm portion and towards the hand portion;
wherein the trough is mechanically rigid and substantially resists flipping, and
wherein the cuff portion remains after the trough is formed.
2. The elastomeric article of claim 1 , wherein the second ridge has a diameter that is in the range of from approximately 1.2 to approximately 1.5 times the diameter of the arm portion.
3. The elastomeric glove of claim 1 , wherein the distance between second ridge and third ridge is in the range of from approximately 1.05 to approximately 1.5 times the distance between the first ridge and the second ridge.
4. The elastomeric glove of claim 1 , wherein the first ridge is a C shaped groove.
5. The elastomeric glove of claim 1 , wherein the third ridge is a C shaped groove.
6. The elastomeric glove of claim 1 , wherein the second ridge is a C shaped projection.
7. The elastomeric glove of claim 1 , wherein the second ridge is a sharp edge.
8. The elastomeric glove of claim 1 , wherein an area between the first ridge and the second ridge is corrugated.
9. The elastomeric glove of claim 1 , wherein an area between the second ridge and the third ridge is corrugated.
10. The elastomeric glove of claim 1 , wherein an area in the cuff portion is corrugated.
11. The elastomeric glove of claim 1 , wherein the latex glove comprises a material selected from the group consisting of natural rubber, synthetic polyisoprene, styrene-butadiene, carboxylated or non-carboxylated acrylonitrile-butadiene, polychloroprene, polyacrylic, butyl rubber, polyester-based polyurethane, or polyether-based polyurethane, or combinations thereof.
12. A process for making an elastomeric glove with an integrally formed arm trough, comprising:
a) creating a glove shaped former comprising a hand portion and an arm portion; the former having a first ridge, a second ridge and a third ridge; the second ridge having a larger diameter than a diameter of the arm portion; a distance between the second ridge and the third ridge being greater than a distance between the first ridge and the second ridge;
b) dipping the former in a coagulant solution to form a coagulant-coated former;
c) withdrawing the coagulant-coated former;
d) dipping the coagulant-coated former in a tank containing an aqueous polymeric latex emulsion;
e) gelling a coating of the polymeric latex on a surface of the coagulant coated former to form a latex coating;
f) withdrawing the former coated the latex coating; and
g) heating the former and the latex coating to a temperature to vulcanize the latex coating to form a cured glove.
13. The process of claim 12 , further comprising washing the cured glove.
14. The process of claim 12 , wherein the first ridge and the third ridge are grooves in the former.
15. The process of claim 12 , wherein the first ridge and the third ridge are projections in the former.
16. The process of claim 12 , wherein the second ridge is a projection in the former.
17. The process of claim 12 , wherein the second ridge is a sharp corner in the former.
18. The process of claim 12 , wherein the second ridge has a diameter that is in the range of from approximately 1.2 to approximately 1.5 times the diameter of the arm portion.
19. The process of claim 12 , wherein a distance between the second ridge and the third ridge is in the range of from approximately 1.05 to approximately 1.5 times a distance between the first ridge and the second ridge.
20. The process of claim 12 , wherein the aqueous polymeric latex emulsion comprises a material selected from the group consisting of natural rubber, synthetic polyisoprene, styrene-butadiene, carboxylated or non-carboxylated acrylonitrile-butadiene, polychloroprene, polyacrylic, butyl rubber, polyester-based polyurethane, or polyether-based polyurethane, or combinations thereof.
