  • Publication number: 20020010413
    Abstract: The present invention relates to applicators for inserting objects into body cavities, and to methods for making the same. The applicators are particularly useful for inserting catamenial and prophylactic devices into a vaginal canal. The applicators comprise a tubular insertion member and a retrofitted gripping member. The gripping member has an outer diameter greater than that of the insertion member. An interface is created due to this size differential, which provides a visual or tactile cue of applicator insertion depth, and thereafter object positioning within the body cavity. The gripping member comprises at least one raised area on its outwardly disposed surface, providing resistance to movement of the user's manual digit in response to longitudinal forces on the insertion member.

  • Patent number: 6264626
    Abstract: The present invention relates to applicators comprising an elongate insertion member having an insertion end and a gripper end opposite thereof, wherein the gripper end has an indentation with a shoulder on each end of the indentation. The shoulder most proximal the insertion end provides resistance to finger slip during the step of inserting the applicator into a body cavity. Whereas the shoulder most proximal the gripper end provides resistance to finger slip during the step of expelling material substantially contained by the applicator. The shoulder most proximal the gripper end also provides secure handling of the applicator while removing the applicator from the body after the expulsion step has been completed.

  • Patent number: 5817077
    Abstract: Vaginal epithelium drying is substantially reduced or prevented by reducing the capillary suction pressure of a tampon in early use. This is accomplished by modifying the capillary suction pressure of the surface of the tampon by using hydrophobic components in the tampon, such as hydrophobic fibers and/or hydrophobic cover material. Other means of obtaining a lower capillary suction pressure include increasing the denier of the fibers in the tampon's absorbent core and/or decreasing the density of the tampon.
