Abstract
A condom comprising a continuous elastic tubular wall with a closed distal end and an open proximal end and further improving features. In one embodiment the condom further comprises a teat at the closed distal end, wherein the teat comprises a neck and a head, and wherein in use, the teat is retained partially or fully inside of the continuous elastic tubular wall, and the teat forms a chamber that is tillable with a fluid or phase change formulation which is released externally in use.
Claims23
A condom comprising:
- a continuous elastic tubular wall with a closed distal end and an open proximal end;
- and
- a teat at the closed distal end, wherein in use, the teat is retained partially or fully inside of the continuous elastic tubular wall, and the teat forms a chamber that is fillable with a fluid or phase change formulation, wherein the chamber has an opening for externally releasing the fluid or phase change formulation in use, wherein the chamber has no fluidic communication with an interior of the condom such that in use no ejaculate can pass into the chamber;
- wherein the condom is configured to capture seminal fluid in a toroidal void around the teat during use.
A condom comprising:
- a continuous elastic tubular wall with a closed distal end and an open proximal end;
- and
- a retaining feature towards a base of the condom, wherein the retaining feature extends circumferentially around the condom and which incorporates a stress relief feature comprising one or more loops which extend along the tubular wall for a length.
A condom comprising:
- a continuous elastic tubular wall with a closed distal end and an open proximal end;
- and
- a longitudinally extended portion of thickened material at a base of the condom, wherein the longitudinally extended portion of thickened material is formed by a portion of the continuous elastic tubular wall being folded over at the open proximal end and adhered to, and/or integrated into, the tubular wall for a part of the length of the condom.
A condom comprising:
- a continuous elastic tubular wall with a closed distal end and an open proximal end,
- wherein the continuous elastic tubular wall has at least one raised feature, each of the at least one raised features having a portion arranged at an angle relative to a longitudinal axis of the continuous elastic tubular wall, and in use create a local force on the continuous elastic tubular wall at an angle to the longitudinal axis to tighten a portion of the continuous elastic tubular wall in response to engagement with a receiving body,
- wherein in use, in response to movement along the longitudinal axis, the at least one raised feature contracts the tubular wall between the at least one raised feature and locally expands the tubular wall outside the at least one raised feature.
A condom comprising:
- a continuous elastic tubular wall with a closed distal end and an open proximal end;
- and
- a seminal fluid retention feature comprising one or more internal inward protruding protrusions extending partially or completely around a circumference of the condom such that a cross-section of the condom is locally reduced, the inward protruding protrusions arranged to retain seminal fluid in the condom.
