Abstract

The present invention relates to a manufacturing apparatus comprising a polymer blade for scraping soap adhered to a roll mill used to make bar soaps. The manufacturing apparatus can be used to manufacture bar soaps, particularly Zinc Pyrithione (ZPT) containing bar soaps, that is characterized by enhanced discoloration resistance and/or improve anti-microbial effect.

First claim

What is claimed is:

1. A manufacturing apparatus for scraping soap adhered to a roll mill comprising: (i) a polymer blade with a scraping surface having a scraping edge contacting the surface of the roll mill; and (ii) a housing supporting the polymer blade and having a compacting surface intersecting the scraping surface at an intersection, wherein the intersection is opposing the scraping edge, and wherein the compacting surface and scraping surface forms a facing angle θ from about 30° to about 80°.

2. The manufacturing apparatus according to claim 1 , wherein the scraping surface has a distance of from about 5 mm to about 15 mm, and the compacting surface extends a distance of from about 6 mm to about 14 mm from the intersection along a plane (L) relative to an axis L of the housing.

3. The manufacturing apparatus according to claim 1 , wherein a ratio of a distance of the scraping surface to a distance of the compacting surface extending from the intersection along a plane (L) relative to an axis L of the housing is from about 1:1 to about 1:3, respectively.

4. The manufacturing apparatus according to claim 1 , wherein the housing further comprises a plurality of channels located at a proximate end of the housing configured to guide scraped soap.

5. The manufacturing apparatus according to claim 4 , wherein each of the channels are defined by flanges attached to a projection that is substantially perpendicular to a plane (L) relative to an axis (L) of the housing.

6. The manufacturing apparatus according to claim 5 , wherein the polymer is a polyolefin selected from the group consisting of low density polyethylene, high density polyethylene, polyolefin plastomers, thermoplastic polyolefins, and block co-polymers of ethylene and propylene.

7. The manufacturing apparatus according to claim 1 , wherein the polymer is a thermoplastic polyolefin selected from a ultra high molecular weight polyethylene or a cross-linked ultra high molecular weight polyethylene.
