Patent Title: Insulating Sleeve
Priority Date: May 4, 2000
Problem(s) Stated: Disposable foamed plastic cups do not insulate a user's hand from the temperature of the liquid inside the container.
Invented Solution: A sleeve made from flexible material will be used in conjunction with a container to insulate a person's hand from the temperature of the contents inside the container through the implementation of a spaced apart portion between the sleeve's side wall and the container's edge.
Claims: (1) The insulating sleeve will conform to the sidewalls of the container, while portions of the sleeve will be positioned angled away from the sidewall and separated in order to create a gap. (4) The sleeve has a structurally weakened area near the said spacer which tears when the container is inserted into the sleeve. (5) The sleeve is shiftable between a flat storage configurations and an open use position. (8) The insulating sleeve has a top and bottom tubular opening for receiving the container.

Patent Title: Insulator sleeve for a beverage containerPriority Date: March 1, 2006
Problem(s) Stated: The use of insulator sleeves instead of double-cupping in order to insulate temperatures has provided economic benefits, but the sleeves themselves have a finite re-usability period before the hinges tear or the paperboard is stained.
Invented Solution: A transparent/translucent, non-disposable sleeve coupled with a disposable beverage container will provide economic benefits while not disrupting the regular workflow of taking orders.
Claims: (1) An insulating sleeve combination comprises of an opaque frusto-conical inner sleeve and a frusto-conical outer sleeve which provides engagement at the interface. At least a portion of the outer sleeve is transparent. The outer sleeve is made of transparent rubber silicon.

Patent Title: Temperature-Indicating Sleeve and Related ContainerPriority Date: December 15, 2006
Problem(s) Stated: Disposable, insulated cups make it difficult for the consumer to determine the temperature of the beverage.
Invented Solution: A temperature-indicating sleeve that is capable of being placed in contact with the outer surface of a container to help the consumer determine whether the contents of the container are at an acceptable temperature for consumption.
Claims: (1) A detachable container sleeve with thermal insulating properties allows visual temperature indication in accordance with the container body. (18) The method of manufacturing the sleeve involves forming a continuous sleeve sidewall with a top and bottom opening and a temperature indicator calibrated to detect the temperature of the contents within the container.
