A shield member may be disposed within the interior volume and secured to one or more portions of the panel assembly, and the shield member may comprise a second material that is different than the first material. The first material may have a wicking barrier that inhibits wicking when the bag assembly becomes wet. The shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank and, together with the wicking barrier and a properly chosen first material, enhances performance of the vacuum bag assembly when wet.Type: GrantFiled: March 28, 2019Date of Patent: May 25, 2021Assignee: SHOP VAC CORPORATIONInventors: James P.

Patent number: 9107549Abstract: Disclosed herein is a vacuum cleaner having a housing defining first and second ports. The vacuum cleaner also includes a cap assembly. The cap assembly includes a cap head to close the first port such that airflow is directed via a flow path to the second port, a sound-influencing material, the sound-influencing material removably held to the cap head and disposed within the flow path to reduce noise effected by the airflow. The flow path is configured to cause the airflow to pass through the sound-influencing material and the flow path to the second port. The sound-influencing material is removable to allow cleaning of the sound-influencing material. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.Type: GrantFiled: November 17, 2009Date of Patent: August 18, 2015Assignee: SHOP VAC CORPORATIONInventors: Robert L. Crevling, Jr., James P. Blackwell, Jr., Matthew S. Kepner

Patent number: 7627928Abstract: Disclosed herein is a vacuum cleaner having a housing defining a blower port, an exhaust port, and a flow path between the blower port and the exhaust port. The vacuum cleaner also includes a removable cap assembly for the blower port to direct discharge airflow via the flow path to the exhaust port. The removable cap assembly, in turn, includes a cap head that engages the blower port to close the blower port, a cap body coupled to the cap head and inserted in the flow path, the cap body comprising a frame through which the discharge airflow passes, and a sound-influencing material supported by the frame within the flow path to reduce noise effected by the discharge airflow. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.Type: GrantFiled: February 17, 2005Date of Patent: December 8, 2009Assignee: Shop-Vac CorporationInventors: Robert L.
