Title: Retrieval cord attachment to feminine tampons - has anchorage using hollow needle device
IPC: A61F13/20
Filed: 1975-01-17
Abstract: To securely anchor a withdrawing cord or filament within a cotton wool mat rolled into a feminine tampon, a hollow needle with the cord fed down its centre is passed through a series of waves formed in the cotton-wool mat by a set of plungers.
