  • Patent number: 11051993
    Abstract: The present invention provides an applicator improved so that the entirety of the tampon may be reliably inserted into vagina. A raised portion is located on an exterior surface of an inner tube in the vicinity of a rear end thereof and put in a slidable contact with a part of an interior surface of an outer tube. The raised portion has an outer shape having a width dimension gradually increasing rearward from an apex located on a front end.

  • Patent number: 9918882
    Abstract: A tampon applicator includes an outer tube for containing at least a part of an absorber therein, a first inner tube and a second inner tube. The second inner tube is telescopically received within the first inner tube. The first inner tube and the second inner tube are connectable to each other during use to push out the absorber from the outer tube. At least a part of the first inner tube and at least a part of the second inner tube overlap with each other in an overlap region outside the outer tube. A color difference between the outer tube and the overlap region is higher than a color difference between the overlap region and the second inner tube.

  • Patent number: 8834438
    Abstract: The covering member includes an inner side surface being in contact with the absorber and an outer side surface to come into contact with a vaginal wall when in use. The covering member contains a hydrophobic fiber with a low affinity to water and a hydrophilic fiber with a high affinity to water. In the outer side surface, an abundance ratio of the hydrophobic fiber is higher than an abundance ratio of the hydrophilic fiber.
