'a Ice Patented Oct. 24, -1961 3,005,543 CLEANING PRODUCT Edward A. Morse, Fanwood, NJ., assignor to Personal Products Corporation, a corporation of New Jersey Filed Apr. 13, `1959, Ser. No. 806,113 2 Claims. (CI. 206-56) The primary object of this invention is to provide an improved means for removing nail polish from the nails of users.

The usual method followed is to wet a small piece of absorbent cotton with a liquid solvent and' apply it to the nails. The solvent either is poured from a bottle or other container onto the piece of cotton or the latter, when attached to a small stick, is dipped into the solvent. Such liquid preparations are difficult to use, since the amount taken from the bottle cannot be accurately controlled. The amount is generally too much or too little and, moreover, frequently nds its way onto nails which do not require repolishing. In addition, spilling is a common occurrence and leads to damage.

Numerous solvents used heretofore as nail polish removers are effective in removing the polish, but in so doing, dry out the nails and adjacent skin, causing them to become brittle and dry. It is necessary, therefore, to include in formulations `containing such solvents a lubricant to offset the drying effect of the solvent.

The present invention overcomes the foregoing and other objections by providing a small pad (about two and one-half inches long and about two inches wide) of absorbent material, such as creped wadding tissue, impregnated with a suitable solvent, such as propylene carbonate, which has a low vapor pressure. Preferably, the pad is formed with a plurality of Janus-faced strips or sections (e.g. five on each face of the pad) which may be used individually for the removal of the nail polish. Such formation of the pad is effected in the course of manufacture by embossing or creasing devices which bond or press the -wadding tissue together ou opposite sides at intervals along its length by the use of high pressure, leaving thin vand narrow connecting Webs which act as hinges to permit the absorbent strips to be bent or folded along the hingelines for individual use. The pad is readily disposable after use, and may be made entirely of tissue which disintegrates readily in water.

The amount of propylene carbonate with which the pad is impregnated is very closely controlled and therefore precludes the possibility of spilling or forming droplets on the nails as it is used. This solvent is non-irritating t the skin and will not only remove the nail polish but also avoid drying out the nails by acting as a plasticizer for the nails to soften them.

The pad, after being impregnated with the solvent, is placed in a sealed package or envelope which is impervious to air, vapor or liquid, such as aluminum or a uoro carbon. This material is entirely compatible with the propylene carbonate solvent. Clt is proposed to place two pads within each envelope in order to provide the user with twenty different polish removing surfaces. The individual packages may be sold as such or sold in larger quantities, say five to a box.

Various other features and advantages of the invention will be apparent from the following description and from the accompanying drawings, in which FIG. 1 is a plan view of an individual pad showing the bonding and division into strips;

FIG. 2 is a transverse section taken on the line 22 of FIG. 1;

FIG. 3 is a plan view of a sealed package containing two Pads; and

FIG. 4 is a longitudinal section taken on the line 4--4 of FIG. 3 and-showing the double layer of pads aswell as the `bonding between strips.

Referring to FIG. 1, the pads 10 are produced from a continuous mat of creped wadding tissue which is formed and shaped by means of applied pressure into a series of double-faced strips, such as 19, 20, 21, 22 and 23, connected by thin webs, such as 13, 14, 15, 16, 17 and 18 located in the central longitudinal plane of the mat. This forming and shaping operation is carried out as a continuous process and also produces thin webs, such as 11 and 12, along the opposite edges of the mat. 'Ihese edge webs not only give a neat and finished appearance to the pad, but they also serve to prevent fraying or unravelling of the tissue strips at the ends.

After being thus formed and shaped, the mat is cut into separate individual pads, each comprising five different strips as shown in FIG. 1 and each strip presenting two polish removing surfaces, one Iat the top and the `other at the bottom. The webs which connect the five different strips, namely, the webs 14 to 17, are located in the central longitudinal plane of the pad and permit the pad to be turned or folded in either direction along the hinge lines formed by the webs, so that either surface of each strip may be used individually in removing the nail polish. The webs 13 and 18 at the opposite ends of the pad 10 are what is left on the pad when it is cut from the wadded tissue mat in the course of manufacture.

At some stage inthe manufacture, either during or after their formation, the pads are impregnated with a measured amount of the solvent, preferably propylene carbonate, which has all the characteristics heretofore mentioned.

Thereafter, and as shown in FIGS. 3 and 4, two impregnated pads 10, one superimposed upon the other, are enclosed in a protective envelope 9 which is sealed along all four edges. -As before stated, this envelope should be compatible with the propylene carbonate and may be composed of aluminum or fluoro carbon which, to repeat, is air tight, vapor tight and liquid tight. Thus, the two-nail polish removing pads are completely protected and preserved until the envelope is opened and a pad removed for use. Once the envelope is opened of course, the solvent will start to evaporate but very slowly I,

because of the low vapor pressureof propylene carbonate.

'I'he envelopes containing the two pads will ordinarily be sold in boxes, say five, ten, twenty-tive, fifty or onehundred to the box.

The invention has been herein shown and described in its preferred form and it is apparent that many changes and variations may be made therein without departing from the spirit of the invention. It is to be understood, therefore, that the invention is not limited to any specific form or embodiment except insofar as such limitations are specified in the appended claims.
