Patent number: 10723496Abstract: Methods, articles, and apparatus that provide a dual function closure/opening system that utilizes a tape serving as both a sealing closure and as an opening mechanism. For example, in one embodiment, a single adhesive tape is introduced between a container flap and a container panel and then the container flap and the container panel are pressed together forming a bond between the flap and the panel via the adhesive tape thereby closing the container. In another embodiment, one end of a container includes two overlapping flaps and a single adhesive tape is introduced between the overlap of the two container flaps and then the container flaps are pressed together forming a bond between the flaps via the adhesive tape thereby closing the container. The methods and apparatus disclosed herein are directed to any container with at least one flap that overlaps a side panel of the container or that overlaps another flap.Type: GrantFiled: June 27, 2018Date of Patent: July 28, 2020Assignee: H.B Fuller CompanyInventors: Matheus W.

Publication number: 20180071436Abstract: The invention provides therapeutic particulates including a macrolide, such as rapamycin, in solid state crystalline form, having a size of 20 ?m or less, or 10 ?m or less. The particulates are formed in one method by preparing a composition with a macrolide and first (e.g., xylene) and second (e.g., an alcohol, acetone, or acetonitrile) solvents. In the composition a maximum solubility for the macrolide that is greater than a maximum solubility of the macrolide dissolved in either the first or second solvent individually. The first and second solvents are then evaporated from the composition to provide the macrolide particulates. In another method, the particulates can be formed by a method including sonication and stirring/evaporation steps, and the particulates can be obtained from a supersaturated solution, formed during the process.Type: ApplicationFiled: September 25, 2017Publication date: March 15, 2018Inventors: Joram Slager, Aleksey V.
