Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a body sponge used for bathing and body sponges.

(Prior Art) As conventional bath sponges, rubber sponges or ordinary soft polyurethane foams having a cell membrane in the form of blocks are often used.

However, these bath sponges do not drain easily, and if left as is after use, water remains in the sponge until use the next day, causing discomfort when reused. In addition, these soaps do not lather well when used with soap, and they also have drawbacks such as the surface feeling slimy when they contain water. Furthermore, there was also the inconvenience that it was not easy to use on the back where it was difficult to reach.

(Problems to be solved by the invention) This invention solves the above-mentioned problems, and aims to provide a body sponge that is comfortable to use and can easily scrub hard-to-reach areas. .

(Means for solving the problem) The body sponge according to this invention is made by folding woven or non-woven fabric made of fibers with a certain degree of rigidity into a long and narrow bag shape, and placing a cell membrane-free soft polyurethane foam inside the center of the bag. It is characterized by being made by fixing a sponge body consisting of.

(Function) The cell membrane-removed soft polyurethane foam that constitutes the sponge body is composed of a three-dimensional network skeleton, and has superior water permeability and foaming properties when using soap compared to ordinary soft polyurethane foams that have cell membranes.

In addition, since the bag-like material which is folded into long thin strips surrounding the sponge body is made of woven fabric or non-woven fabric made from fibers having a certain degree of rigidity, its surface has appropriate rigidity and roughness. Moreover, it does not feel slimy even when it contains moisture.

Therefore, this device consisting of the sponge body and the bag-like material has good drainage and foaming properties, and also does not have a slimy feeling even when used in a state containing water, and has an excellent feeling of use. Also, if you use it by holding both ends of a long and narrow bag with your hands, it can be passed through your back, waist, etc.
You can easily rub hard-to-reach areas such as your back and waist with the sponge body.

(Example) Fig. 1 is a partially cutaway perspective view of a body sponge according to an embodiment of this invention, seen from the back side, and Fig. 2 is an A-A
It is a sectional view along a line. This embodiment will be explained below based on the drawings.

The illustrated body sponge is composed of a folded elongated bag-like material 10 and a sponge body 12 fixed approximately inside the center of the bag-like material 10.

The bag-like article 10 is formed by folding a woven fabric or a non-woven fabric made of fibers having a certain degree of rigidity such as nylon fibers, such as a nylon towel, so that both end portions 10a and 10b perpendicular to the longitudinal direction thereof overlap. The bag-like object 10 has a sponge body 12 disposed approximately in the center thereof.
The front and back sides are sewn together with sewing thread 14 at this position and other predetermined positions for decoration, and if necessary, a handle string 16 is provided at the end.

The sponge body 12 is made of a soft polyurethane foam from which a cell membrane has been removed, and from the viewpoint of water permeability, tactility, etc., a sponge body 12 preferably has a cell count of approximately 20/cm.
Note that the cell membrane-removed flexible polyurethane foam can be easily obtained by subjecting a conventional flexible polyurethane foam having a cell membrane to known means such as alkali treatment and heat treatment, so detailed description thereof will be omitted.

A body sponge made in this manner can be obtained by folding a bag-like material around the sponge body as shown in Fig. 3, or by wrapping the bag-like material around the sponge body, or by stretching the bag-like material as shown in Fig. 1. It is used by placing the sponge part on your back, waist, etc., and grasping both ends of the bag with your hands.

(Effects) As mentioned above, this device is made by fixing a sponge body with good water permeability and soap lathering property approximately in the center of a long and narrow bag-like object with appropriate rigidity and roughness. Even if you leave the sponge without squeezing out the water after use, the water inside the sponge will leach out to the outside and dry up by the next day, so it won't cause discomfort when reused, and the soap will foam well and stay moist. There is no slimy feeling when using it, it is easy to use in hard-to-reach areas, and it can provide optimal friction and stimulation to the skin for body pine surgery for health and beauty purposes. .
