Publication number: 20240101319Abstract: An example lid assembly can include a lid and a slider. The lid can include a wall defining a recess. The slider can be configured to slide in the recess and can be configured to move between a closed position where the slider covers an opening to aid in preventing spilling of contents of the container, and an opened position where the slider uncovers the opening such that the contents may be poured from the container. The slider can be configured to be removable from the lid and can be replaced back on the lid. Additionally, the slider can be formed from upper and lower sled elements 130,136 that are magnetically coupled to one another. In some examples, the lower sled of the slider may include an air vent with rounded entry portions, and the lid assembly may include engaging members with ramped surfaces.Type: ApplicationFiled: April 30, 2021Publication date: March 28, 2024Inventors: Cody Jinkins, Andy Bondhus, Mark Carlson Rane, Dustin Bullock, John Fritz, William Drinkwater, Matthew Bryson, Elizabeth Ruchte

Patent number: 8562025Abstract: An optical security label for security and anti-counterfeit applications comprises a first layer having an optically variable portion (diffractive, holographic or interference film) generating an optically variable effect secured to a support layer by a weak adhesive layer such that the first layer can be scratched off the third support layer to reveal underlying data and the label is affixed to a substrate by a pressure sensitive adhesive. The label or substrate carry the data to be protected such a printed or personalized paper or plastic substrate. In one aspect the scratch off region is patterned and also the data can comprise a pattern of alternate scratch off and permanent areas. In one aspect the label is a thin frangible structure delivered to the substrate with a weakly bound top carrier. In another aspect the optical variable device includes a covert image authenticated by a decoder carried on the top of the removable carrier.Type: GrantFiled: February 5, 2003Date of Patent: October 22, 2013Assignee: Optaglio LimitedInventor: Kenneth John Drinkwater
