Patent number: 11472156Abstract: The present disclosure generally relates to conformable adhesive articles that are capable of attaching or adhering to a substrate and that can be removed from the substrate without causing damage to the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles. In some embodiments, the adhesive article includes (1) a releasable layer having a first major surface and a second major surface; the second major surfaces including a pressure sensitive adhesive capable of adhering the adhesive article to a surface; and (2) a compliant layer having a first major surface and a second major surface; the second major surface of the compliant layer adjacent to the first major surface of the releasable layer. In some embodiments, the releasable layer debonds from both the surface and the compliant layer when the adhesive article is stretch released at an angle of less than 35 degrees.Type: GrantFiled: March 26, 2018Date of Patent: October 18, 2022Assignee: 3M Innovative Properties CompanyInventors: Megan P. Lehmann, David J. Yarusso, Christina D. Cowman-Eggert, Barbara K. Schmotter, Corinne E. Lipscomb

Publication number: 20210085080Abstract: The present disclosure relates to improved furniture pads that provide an opportunity to repair the connection between the pad and a furniture surface, the integrity of the pad, or both. In some instances, this can be accomplished by providing a pad comprising multiple pad bodies, each of which can has a protective surface. The pad bodies can be stacked or removed depending on the relationship between the furniture and the floor. In other instances, multiple adhesive layers are arranged on the top surface of a protective pad body, allowing for an adhesive bond to be refreshed and restored if the pad fails.Type: ApplicationFiled: February 5, 2019Publication date: March 25, 2021Inventors: Kyle E. Kulseth, Landon B. Davis, Tatiane Dias Marques Faria, Debora F. Barron, Angela L. Pan, Kristine K. Krumhus, Christina D. Cowman-Eggert, Aaron P. White
