Abstract
This invention relates to a tampon (10). The tampon includes an elongate absorbent body (12) and at least one surface formation (34, 36, 38, 40) applied over an exterior surface of the absorbent body. The at least one surface formation is of a material different to the absorbent body and is configured to inhibit expansion of at least a portion of the absorbent body i-n use due to absorption of menses by the absorbent body, and/or to facilitate insertion and seating of the tampon in a vagina. The invention extends to a tampon which includes an elongate absorbent body which is non-circular in outline in end view. The invention further extends to a tampon which has a particular correct angular orientation relative to its longitudinal axis, with which it is to be inserted into a vagina, the correct angular orientation being clearly visible to a user.
