SOAP BAR Filed Dec. 2l, 1953 ,Zwaar/7a? ,if

fiar/ffy Patented Nov. 6, 1934 circo STATES PATENT'` OFFICE 15 Claims.

My present invention relates to improvements in the construction of soap bars, and has par ticular reference to soap bars suitable for .re-

moving dirt and grime from the hands. i Soap bars which have heretofore been manufactured for scrubbing purposes have included abrasive ingredients which have not been suitable for delicate skins, and have roughened the hands ci a user. It is the principal object of i my invention to provide a soap bar construction which will facilitate the removal of dirt and grime without, however, abrading or roughening the hands oi the user. i

The soap bars, as at present manufactured,

have also been subject to another disadvantage in that there is no -rm support for the soap material; it has therefore been impossible to use a relatively soft base soap. A further object of my invention is to provide a reenforcing or strengthening structure for the soap bar which will enable the bar to retain its shape at all times and will therefore permit the use of standard soap mixtures, and also of soap mixtures for special purposes which may have a relatively softbcdy.

With the above and other objects and advantagecus features in view, as will hereinafter appear, my invention consists of a novel arrangement of `parts more fully described in the detailed description following, in conjunction with the accompanying drawing, and more speciilcal-| ly defined in the descriptions appended thereto.

In the drawing,

Figure l is a perspective View of the novel soap bar; v

Figure 2 is a transverse section therethrough on line 2--2 of Figure 1;

Figure 3 is a section of the bar after use taken on a line corresponding with line SH3 of Figure 1 in order to better disclose the projecting edges of the scrubbing ingredient, these edges being for iliustrativepurposes exaggerated in height;

Figure 4 is a perspective view of two of the scrubbing elements, showing their locking relationship; and

Figure 5 is a fragmentary section on line 5 5 oi Figurey 4. l

1t has been found desirable to construct -a soap bar so as to permit a gentle, non-abrasive scrubbing section, and at the same time to include a support for the soap material. I have, therefore, incorporated a scrubbing ingredient into a soap bar, comprising a substance which` will wear away at about the same rate as the soap material, but will present a plurality of scrubbing edges to contact the hands of the user and rapidly remove dirt and grime therefrom.` The scrubbing'ingredient is nonabrasive, a preferred? material being thick wood pulp paper, and this scrubbing ingredient is incorporated in the soap bar as a plurality of interlocking strips which may also be bound with the soap material; the division of the scrubbing material into a plurality of interlocked strips provides a support for` the soap material which extends throughout the length and breadth of the soap bar.

An illustrative embodiment of my invention is shown in the drawingthe novel soap bar being designated by the reference character 10, and including the soap material 11, in which a plus rality of scrubbing strips 12 are iirmly embedded, these elements being closely spaced and extending lengthwise and crosswise oi the soap bar, as indicated in Figure 1. Each strip l2is stamped or otherwise formed from a sheet of scrubbing material, and includes a central section 13 and a plurality of spaced sections 14, extending laterally therefrom, the central section being slotted on one side intermediate the spaced sections, as indicated at l5.

It is therefore possible to lock the sections together, as indicated in Figure 4, with the slots l5 oi' the interlocking sections in alignment and contacting the solid portions of the center section adjacent the slots, whereby the scrubbing strips may be interlocked and the soap material molded therearound so as to permanently imbed the interloclzed sections therein. If desired, the sections may be provided with a plurality of openings 16 for permitting inclusion of the soap material during the molding operation, in order to thoroughly interlock and band the sections with the soap material as well as with each other.

The novel soap bar thus includes a plurality of scrubbing strips which are permanently imbedded therein, these strips having a multiplicity of spaced edges, designated as 17 in the drawing, which form part oi the bar surfaces and contact the skin of the userwhenwashing the hands to exert an effective-scrubbing action for assisting in the removalfof dirt andgrime. As the soap wears down, these edges will `always y project slightly above the surface of the soap bar, but will wear away Vat about the same rate as the soap material; the projecting edges, however, constantly present a criss-cross of dirt and grime removing bands which persist until the soap bar is completely used, as `the strips also serve to support the soap material and maintain it in proper shape during the entire life of the soap bar.

If desired, the scrubbing strips may be arranged in different designs, as for example for spelling the name of the manufacturer or the like, as it is evident that the name Will persist in view until the soap bar is entirely worn out.

While I have illustrated and described a speciiic arrangement of scrubbing elements in a soap bar, and have indicated that a preferred scrubbing material is paper made out of short fiber material such as wood pulp so as to permit a wearing away at the same rate as the soap material, it is obvious that desired changes in the shape and form of the scrubbing strips, in the character of the material forming the strips, and in their relative positioning' within the soap bar, may be made as desired, Within the spirit and the scope of my invention as defined in the appended claims.

l. In a soap bar, soap material, and a plurality of elements of short fibre material embedded therein, said elements extending longitudinally and transversely of said bar and extending to the upper and lower surfaces thereof, whereby said elements present scrubbing edges as the soap material wears away.

2. In a soap bar, soap material, and a plurality of interloclred elements embedded therein, said elements extending longitudinally and transversely of said bar and extending to the upper and lower surfaces thereof, whereby said elements present scrubbing edges as the soap material Wears away.

4. In a soap bar, soap material, and a plurality of inter-locked elements in strip form and embedded therein, said elements extending longitudinally and transversely of said bar and extending to the upper and lower surfaces thereof, whereby said elements form a support for the soap material adapted to be worn away during use of the soap bar at substantially the same rate of wear as the soap material.

5.
