  • Patent number: 10723496
    Abstract: 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.

  • Publication number: 20190002145
    Abstract: A method of applying a tape to an article. The method includes contacting a first activatable adhesive composition of an adhesive tape with a placement device. The adhesive tape has a carrier substrate, the first activatable adhesive composition disposed on a first surface of the carrier substrate, and a second activatable adhesive composition disposed on a second surface of the carrier substrate. The method includes activating the first activatable adhesive composition such that the adhesive tape adheres to the placement device through the first activatable adhesive composition, separating the adhesive tape from a tape delivery system, activating the second activatable adhesive composition, contacting an article with the second activatable adhesive composition, and separating the placement device from the adhesive tape such that the adhesive tape remains adhered to the article.

  • Publication number: 20180071436
    Abstract: 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.

  • Patent number: 9629945
    Abstract: The invention is directed to latent reactive and polymerizable derivatives of fluorescent stilbene-based compounds. The compounds can be used to provide articles with a fluorescence property, such as medical devices (e.g., catheters). The fluorescent compounds can be used in association with polymers, or can be incorporated into polymers, and the polymers used in a coating composition on the article surface. The compounds allow for visual or machine inspection of coating properties such as uniformity of coverage.
