ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a facial cleansing purpose foaming device that can produce soapsuds containing a mass of fine bubbles when one's make-up is taken off or the facial cleansing is done, using facial cleansing material, such as liquid deterget or solid soap.
2. Prior Art
Unclean substances, such as sebaceous membranes oxidized with age, horny cell layers matured into dirt, make-up stains, dust in the air, or bacteria, adhere to the facial skin and block pores in the facial skin. Failure of an adequate skin-care may cause a pimple with inflammation.
For prevention of development of the pimple and rough skin, it is necessary to remove unclean substances from the skin surface and constantly keep the skin surface clean. The basics of keeping the facial skin clean is to wash one's face or facial cleansing.
Sebum includes salt and urea contained in sweat, resident flora of skin, or contaminant in the atmosphere, and these substances are decomposed by ultraviolet rays and oxygen in the air or breed in the skin, to adversely affect the skin.
Cosmetic materials, such as powdered cosmetic material or oils and fats of the cosmetic material, remaining on the skin surface, particularly in the pores in the skin, are mixed with the decomposed sebum to adversely affect the skin. Washing one's face or facial cleansing is effective for removing those substances from the skin surface to keep the skin surface clean and it is the basis of facial treatment.
In general, when the facial cleansing is done for taking off one's makeup or the like, one takes up cleansing material, such as solid, liquid or powdered facial soap (detergent) and rubs it with one's hands to produce soapsuds and then applies the soapsuds onto one's face.
When the soapsuds are produced by rubbing the cleansing material with one's hands, not much air is let into the cleansing material. It takes a lot of time to produce the soapsuds, and also the soapsuds thus produced are in a paste-like form and have a small foam height. Accordingly, one is inclined to consume an increased quantity of cleansing material and, as a result, the soapsuds becomes an irritant for the skin to that extent, which may provide an opposite effect of accounting for the rough dry skin, rather than the cleansing effect.
To cope with this problem, a facial cleansing purpose foaming device formed of a fine-meshed, low-stretch, tubular net was proposed, as disclosed by, for example, Japanese Laid-open patent publication No. 10(1998)-276928, according to which the net is collected at its opposite ends and fixedly tightened with strings or cramps or by thermowelding or equivalent and an operating part is formed at one end thereof.
This type of facial cleansing purpose foaming device has following disadvantages, however. First, since the net is collected and tightened at the opposite ends with the cramps or by thermowelding and thus becomes stiff at the collected portions, when the soapsuds are squeezed out from the facial cleansing purpose foaming device by grasping one end of the foaming device with one hand and drawing the foaming material through the other hand, the stiffly collected portions become a hindrance.
Second, since the collected portions are rolled in between one's hands joining together for the foaming, it gives an uncomfortable touch to the user.
Third, since the tubular body of the net is closed at its opposite ends, when the net is used in combination with a solid face soap, for example, it is necessary for the soap to be applied to each side of the net and, accordingly, it takes a lot of trouble to produce soapsuds, and also the soap is easily slipped off when the facial cleansing purpose foaming device is handed off from one hand to the other hand.
SUMMARY OF THE INVENTION
In the light of the disadvantages mentioned above, the present invention has been made. It is the object of the present invention to provide a facial cleansing purpose foaming device that can produce creamy soapsuds containing a lot of small bubbles with ease, and which also can squeeze out the produced soapsuds with ease.
To accomplish the above-noted object, the present invention provides a novel facial cleansing purpose foaming device comprising a tubular body which is formed of a flexible material being formed into a net-like form from synthetic resin material or synthetic resin fibers to have air permeability and water permeability. The body comprises a gripping portion fitted to one end thereof and an opening formed at the other end thereof, and is structured so that it can contain therein solid cleaning material inserted from the opening. According to the present invention, when the facial cleansing purpose foaming device impregnated with cleaning material is interposed between both hands and then is rubbed therewith, a large quantity of soapsuds can be produced. Thereafter, when the gripping portion is grasped with one hand and the body containing the soapsuds is drawn through the other hand, the creamy soapsuds inhaling lots of air can be squeezed out easily from the unrestrained opening, without any hindrance from the stiffly collected portion formed by solvent welding and the like, as in the prior art. Also, different from the prior art, since the body of the facial cleansing purpose foaming device to be rubbed is opened at one end so that no stiffly collected portion is formed thereat, it provides a comfortable touch to the user without any uncomfortable touch to the user.
It is preferable that the gripping portion is provided with a suspending/drawing ring. The arrangement of the ring in the gripping portion can provide the advantages of allowing an easier drawing of the body through the hand; of making the device hard to lose or drop; and of facilitating the drip of water so that the facial cleansing purpose foaming device can be dried quickly to maintain hygiene.
In addition, it is preferable that the body is doubled by folding back the material forming the body at the opening. With this arrangement, the folding portion also has adequate flexibility, so that for example the solid soap can easily be inserted and removed from the opening. Also, there is provided the advantage that when the solid soap and something similar is inserted in the body, the soapsuds can readily be produced from each side of the body, without handing off the body from one hand to the other hand, as in the prior art.
