Abstract: A mixing device including a blade with radially outwardly extending arms and/or with a longitudinally extending wall with an elliptical cross-section. The elliptical cross-section may synergistically provide enhanced mixing and enhanced durability of the blade compared to previously known joint compound mixers. For example, the elliptical cross section may provide structural support to the radially outwardly extending arms and/or the longitudinally extending walls while allowing the radially outwardly extending arms and/or the longitudinally extending walls to cut through and spread joint compound. The structural support may allow the blade to be made of a plastic material. For example, the blade may be made of acrylonitrile butadiene styrene (ABS). Making the blade out of plastic may reduce scratching and degradation of the container that holds the joint compound during mixing, compared to previously known drywall mixers made of metal.

Abstract: The present disclosure provides a drywall tool including a scraping portion having an outwardly curved front portion extending between parallel side edge portions and a support member joined to the scraping portion by at least one fillet. The scraping portion may also be flexible to conform to the inner wall and resilient enough to prevent bending of the scraping portion around hardened putty or other materials attached to the inner wall of the bucket. The fillet may also provide a smooth connection to facilitate cleaning of the drywall tool.

Abstract: A dispenser for dispensing drywall tape and joint compound includes a first port configured to deposit the joint compound on a first region of the tape at a first thickness, and to deposit the joint compound on a second region of the tape at a second thickness, wherein the first thickness is greater than the second thickness.
