Bath sponge
A bath sponge is formed from a foamed polyurethane to have a plurality of relatively shallow and small pores distributed over an outer surface thereof, and is provided on or between the shallow and small pores with a plurality of staggered and relatively deep and large holes resembling seawater corroded holes. Each of the relatively deep and large holes is internally provided at a bottom with a deeper and size-reduced hole, which do not extend through the bath sponge. Therefore, the bath sponge not only has an appearance like a natural sponge, but also has structural strength, breaking resistance, water absorbing ability, and softness better than both the natural sponge and other general types of bath sponge.
The present invention relates to a bath sponge, and more particularly to a bath sponge that not only has a beautiful appearance like a natural sponge, but also has structural strength, breaking resistance, water absorbing ability, and softness better than both the natural sponge and other general types of bath sponge.
BACKGROUND OF THE INVENTIONWhile natural sponge is soft and provides good water absorbing ability, and therefore has been collected from deep sea for use, the natural sponge is rare and expensive and could not be mass produced. Moreover, the natural sponge has a bad odor and is not easily widely accepted by consumers. The natural sponge has pores that normally extend through a full thickness of the sponge. Due to this structure, the water-absorbed natural sponge becomes too soft and thin for use. Meanwhile, the large-scale collection of the natural sponge would endanger the natural ecological balance in the ocean.
Therefore, it is tried by the inventor to develop a bath sponge that resembles the natural sponge in appearance but has structural strength, breaking resistance, water absorbing ability, and softness better than the natural sponge.
SUMMARY OF THE INVENTIONA primary object of the present invention is to provide an improved bath sponge that not only has a beautiful appearance like a natural sponge, but also has structural strength, breaking resistance, water absorbing ability, and softness better than both the natural sponge and other general types of bath sponge.
To achieve the above and other objects, the bath sponge of the present invention is formed from a foamed polyurethane to have a plurality of relatively shallow and small pores distributed over an outer surface thereof, and is provided on or between the shallow and small pores with a plurality of staggered and relatively deep and large holes resembling seawater corroded holes. Moreover, each of the relatively deep and large holes is internally provided at a bottom with a deeper and size-reduced hole, which does not extend through the bath sponge.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
Please refer to
With the relatively deep and large holes 12 staggered on or between the relatively shallow and small pores 11, the outer surface of the bath sponge 1 having been wetted for use can be more easily deformed at a large deflection angle, as shown in
The deeper and size-reduced holes 121 at the bottom of the relatively deep and large holes 12 provide the bath sponge 1 with improved water absorbing and discharging ability, so that water and bath lotion may move into the bath sponge 1 more easily to enable enhanced cleaning effect.
Claims
1. A bath sponge, comprising a body formed from a foamed polyurethane (PU), the body having a plurality of relatively shallow and small pores distributed over an outer surface thereof, and a plurality of staggered and relatively deep and large holes resembling seawater corroded holes provided on or between the shallow and small pores, and each of the relatively deep and large holes being internally provided at a bottom with a deeper and size-reduced hole having a diameter smaller than the deep and large holes.
2. The bath sponge as claimed in claim 1, wherein the staggered and relatively deep and large holes and the deeper and size-reduced holes provided at the bottom thereof do not extend through a full thickness of the body of the bath sponge.
