Description

BACKGROUND

This invention, in general, relates to toiletries. More particularly, this invention relates to an apparatus for cleaning and maintaining the personal hygiene of a user.

Natural and man-made sponges, loofahs, and nylon poufs are often used for personal cleaning. Natural sponges are manufactured from animals and loofahs are manufactured from plants; hence natural sponges and loofahs are susceptible to rotting and parasite infestation. There is a need for a personal cleaning apparatus which is not susceptible to rotting and infestation.

Nylon poufs are usually made from a folded nylon mesh tied together in the center. The nylon mesh tied at the center creates a wavy, uncontrolled structure which limits the nylon mesh's useful cleaning area. During use, nylon poufs also need to be held by the nylon mesh itself. Additionally, some nylon poufs are attached to a grasping device using a central tying device. The current grasping devices provide limited useful cleansing control.

Hence, there is a need for a personal cleaning apparatus having a firm grasping area for greater cleansing control. Moreover, there is a need for a personal cleaning apparatus that utilizes an ordered set of layers of nylon mesh instead of a random wavy mesh for improving aesthetics, exfoliating, cleaning and massaging properties of the cleaning apparatus.

Additionally, most personal cleaning products that are marketed target female consumers. Hence, most personal cleaning products are manufactured in colors and designs more appealing to female consumers. Hence, there is a need for an apparatus for maintaining the personal hygiene of a user by exfoliating, cleaning, and massaging the user's body while remaining gender neutral in design.
