A bar soap recycling device including an enclosure assembly, a tray assembly, an electrical assembly, and a soap assembly is disclosed. These assemblies in conjunction with one another provide a simple solution to recycling used bars of soap. Leftover chips, slivers, or pieces of used soap bars are placed within a mold of the tray assembly. The tray assembly is placed within an enclosure that includes an integrated heating element. The heating element warms the heat conducting mold to the point of melting the used soap bars. A timer determines when the soap bars have had enough time to melt into the shape of the mold. A cooling element in the form of a fan then cools the mold and soap contained therein to resolidify the used bars of soap into a single bar. The resolidified bar of soap is then removed from the mold and ready to be used.

The present disclosure is directed to dissolvable objects in the form of a bar of soap. The dissolvable objects are dissolvable in a solvent, such as water in a bath tub. The dissolvable objects are further configured to release an additive, or a collection of additives, which can be embedded within the bar of soap. The present disclosure is also directed to methods of manufacturing a bar of soap.

A soap bar forming apparatus and method for forming a soap bar by compression welding a plurality of soap slabs is configured to mechanically weld a plurality of soap slabs into a single soap bar of a usable size. The soap slabs are placed on the open top chamber of the lower casing in a flat stacked position. The upper casing is then placed over the lower casing and then both the casings are tied in place by the Velcro straps. The upper casing detachably couples to the lower casing and a pair of detachable straps fasten the casings together. A drive member presses the soap slabs together, and comprises a rotatable compression screw terminating at a compression plate, and an E-Ring that fastens the compression screw and compression plate together, and allows the compression screw to rotate while the compression plate moves up and down without twisting. The rotatable compression screw rotatably passes through the threaded drive hole in the upper casing, forcibly urging the compression plate onto the soap slabs to compress the soap slabs into a single large soap bar.

Methods and systems to manufacture a soap bar comprising post-brew coffee particles are disclosed. A soap bar may comprise multiple post-brew coffee ground particle sizes to take advantage of the benefits associated with each size. For example, the soap bar may comprise espresso grinds (0.20 mm), regular grinds (1.0 mm), and/or coarse grinds (1.5 mm). A saponified fat base, e.g., a milk soap base, a plant oil base, and/or an animal fat base may be obtained and heated to a consistency. Collected post-brew coffee grounds may then be added. The coffee grounds may be anywhere from 1% to 65% of the total weight of the final product, depending on the desired soap quality. The final soap product may comprise coffee ground positive and coffee ground negative layers or portion, or the coffee grounds may be evenly dispersed throughout the product.

A solid soap composition includes soap in an amount of at least 70% by weight of the solid soap composition. The solid soap composition (i) has a pH of from 7 to 9.5, and (ii) contains water in an amount of from 0.01 to 15% by weight of the solid soap composition.

A method of producing a solid soap containing at least one image embedded within the solid soap includes printing an image on a dissolvable substrate to form an image layer, bringing the image layer into contact with molten soap and allowing the soap to harden so as to embed the image layer within the solid soap. The dissolvable substrate can be a printable icing or frosting sheet and the image can be a high-resolution image. The soap can include a background layer against which the image is visible.

A method of molding soap for forming decorative shapes includes a housing that has a top surface, a bottom surface and a perimeter wall that is attached to and extends between the top surface and the bottom surface. A heating unit is mounted in the housing. When turned on the heating unit heats the top surface. A plurality of molds, each has a different shape. One of the molds is selected to define a selected mold. The selected mold is positioned on the top surface such that the selected mold is in thermal communication with the heating unit. A bar soap is positioned in the selected mold. The heating unit is turned on such that the bar soap melts to define fluid soap. The heating unit is turned off to allow the fluid soap to solidify to define a molded soap. The molded soap is removed from the selected mold.
