Definitions

  • This invention relates to soap in cake form, one of. the objects being to provide a hard milled soap, cocoa soap, glycerine soap, etc., which is capable of floating without necessi- 5 tating the use of foreign substances of a buoyant nature.
  • the most desirable soap is a hard one, suchas pumice, castile, coco'a, glycerine, or milled soap none of which soften readily but can .19 'usuallybe worn down to a thin wafer.
  • Such soaps are heavier than water and, therefore, will not float. For" this reason only'they are not preferred by some persons for use in lieu of the softer, less durable, but
  • Another object is to provide a soap in which the means utilize for rendering it buoyant can also be employed as a means for outlining a distinctive nameor mark which will remain in the soap and be legible at all times until the cake is worn to a thin .wafer.
  • A-further object is-to provide a soap in which the means utilized for rendering it buoyant-also serves to hasten the curin of 40 the soap with the result that, instead 0 requiring a curing action extending over several months or more, the soap can be completely cured or-har'dened within a fewweeks:
  • Figure 1 is a plan view of a cake ofsoap embodying the present improvements.
  • Figure 2 is a section on line 2'-'2, Figure 1.
  • Figure 3 is a plan View of another form of a cake of soap.
  • Figure 4 is a section on line 44, Figure 3.
  • Figure 5 is a plan view of another modified form.
  • Figure 6 is a section on line 6 6, Figure 5.
  • 1 designates a cake of hard soap such as herein mentioned which can be of any desired contour and size.
  • a distinctive design has been molded on the cake as shown at 2 and this design has been'outlined by a plurality of elongated recesses 3 extendin inwardly close to the center of the cake.
  • ach recess thus constitutes an air pocket and the totalarea of the recesses is suflicient to hold more'than enough air to compensate for the slight difference in the specificgravity between the soap and water.
  • a cake of soap rovided with these air pockets is placed in a ody of water sufficient air will be trapped in certain of the pockets to render the cake buoyant.
  • the depth of the pockets will of course be reduced but as the size of the cake is correspondingly reduced the buoyancy of the cake will be maintained untilthe cake is reduced to a thin and substantially useless wafer.
  • pockets or recesses 3 useful as a mean for trap ing air and rendering the soap buoyant, but t ey are also useful because the p preserve the distinctive name or mark out 'ned thereby, as the cake becomes worn. Thus the brand of the cake can be identified at different stages of use.
  • a further im ortant advantage resides in the fact that t ese pockets or'recesses expose the interior portion 100 of the cake to the air so that the time required to completely harden the cake by curing is greatly reduced.
  • the soap brand consists of a series of cells or pockets along the edges of the faces of the 1 cake. These pockets or cells, indicated at 8, converge toward the center of the cake 9 and when the cake is placed in a body of water enough air will be trapped in some of the cells to render the cake buoyant.
  • the cells When any of the cakes of soap are used the cells will become partly or entirely filled with lather but this will not reduce the buoyancy of the soap cake because air in suflicient quantities to render the cake buoyant will be mixed with the-lather. Some of the cells will also become sealed by the compression of soap at the outer ends thereof but this obviously serves to trap the air in the cells.
  • a cake of milled soap having bores extending thereinto from opposed ortions of the cake, said bores being of sma 1 diameter but of sufiicient depth and number to render the cake buoyant, the outer ends of the bores bleingd substantially open and the inner ends 0 o 2.
  • a cake of milled soap having bores extending thereinto from opposed portions ofv the cake, said bores being of small diameter but of suflicient depth to render the cake buoyant, the outer ends of the bores being substantially open and the inner ends closed,
