Abstract
A generally loose-fitting tubular sheath article (1), such as a condom, which has a closed distal end (2) and an open proximal end (14) which is bounded by a knitted material (18) that bears compressively on the sheathed member to provide retention. The knitted material may be in the form of a band which is affixed to the sheath by everting a portion (20) of the sheath material at the proximal end over the knitted material and attaching the sheath material to itself, thereby creating the toroidal enclosure in which the knitted material is disposed. Constriction of the sheathed member is minimized by the knitted material which provides a large surface area for retentive contact.
Claims
1. A sheathing article for protective covering of a sheathable part, comprising:
(i) a generally tubular sheath member having a closed first end and an open second end defining an enclosed interior volume within the sheath member, accessible by the open second end, for introduction of the sheathable part into the interior volume through the open second end;
(ii) a knitted retention structure associated with the sheath member at a proximal portion thereof in the vicinity of its open second end, for exerting a compressive retaining action on the sheathable part at the proximal portion of the sheath member, said knitted retention structure comprising a knitted material band circumscribing the exterior surface of the sheath member at its proximal portion; and
(iii) a circumferentially extending proximal compartment at the proximal portion of the sheath member, wherein the proximal compartment comprises an exteriorly everted skirt segment of the sheath member, secured to the exterior surface of the sheath member to define an internal compartment volume containing the knitted material band.
2. An article according to claim 1 , wherein said knitted material band has a diameter of form about 25 millimeters to about 55 millimeters, and wherein the sheathing article is of a size adapted for sheathing of a penis.
3. A sheathing article for protective covering of a sheathable part, comprising;
(i) a generally tubular sheath member having a closed first end and an open second end defining an enclosed interior volume within the sheath member, accessible by the open second end, for introduction of the sheathable part into the interior volume through the open second end; and (ii) a knitted retention structure associated with the sheath member at a proximal portion thereof in the vicinity of its open second end, for exerting a compressive retaining action on the sheathable part at the proximal portion of the sheath member, wherein the knitted retention structure comprises a knitted band characterized by: an Equivalent Diameter Garter Force Value of from about 0.04 to 0.06 kilograms at 33 millimeters and from about 0.60 to about 0.90 kilogram at 48 millimeters; a Mandrel Retention Force Creep Value of from about 0.30 to about 0.35 kilogram; and a Relaxation Creep Value of from about 10% to about 40% over a strain range of from 30% to 130%.
4. An article according to claim 3, wherein the knitted retention structure comprises a knitted web strip circumferentially extending at least partially about the exterior surface of the sheath member at its proximal portion.
5. An article according to claim 3, wherein the knitted retention structure comprises yam selected from the group consisting of: staple yarns; filament yarns; and combinations thereof.
6. An article according to claim 3, wherein the knitted retention structure comprises elastomeric yarn.
7. An article according to claim 6, wherein the elastomeric yarn is formed of a material selected form the group consisting of rubber, spandex, copolyetheresters, texturized nylon, and combinations thereof.
8. An article according to claim 3, wherein the knitted retention structure comprises yarn formed of a material selected from the group consisting of: acrylics; polyesters; polyamides; rayon; cellulose acetates; silk; wool; cotton, polypropylene; polyurethane; copolyetherester; rubber; polyvinyl chloride; polyvinylidene chloride; polyvinyl alcohol; linen; flax; polyethylene; polyaramide; spandex; copolymers of monomers of said polymers; and composites, combinations, and multicomponent forms thereof.
9. An article according to claim 3, wherein the knitted band comprises a needle- knitted material having a needles per course characteristic of from 56 to 110 needles per course.
10. An article according to claim 3, wherein the knitted retention structure comprises a yarn consisting of two ends of false-twist textured nylon and one end of spandex.
11. An article according to claim 10, wherein the spandex yarn is S, Z wrapped with nylon.
12. An article according to claim 3, wherein the knitted band has a diameter of from about 25 millimeters to about 55 millimeters, and wherein the sheathing article is of a size adapted for sheathing of a penis.
13. A method of making a sheathing article, comprising:
(a) providing a generally tubular sheath member having a closed first end and an open second end;
(b) disposing a circumferentially extending knitted retention band about an exterior surface of the second end portion of the sheath member, in spaced relation to the open second end thereof, to thereby define a proximal segment of the sheath member between the knitted retention band and the open second end;
(c) everting the proximal segment of the sheath member between the knitted retention band surface region of the sheath member, to form a enclosure volume containing the knitted retention band.
14. The method of making a sheathing article according to claim 13, wherein said securing of the everted proximal segment of the sheath member to an overlaid exterior surface of the sheath comprises heat sealing of the everted proximal segment of the sheath member to an overlaid exterior surface of the sheath.
