  • Patent number: 5794843
    Abstract: Corrugated cup wraps which are made of recyclable material that are held adhesively to cups without encircling the entire circumference of the cups. The cup wraps are made of a corrugated material that is fluted for air ventilation which facilitates the quality of a thermal barrier between the cup and the hand holding the cup wrap-wrapped cup. These cup wraps are flexible and easy to wrap around paper cups and attach to paper cups when the paper cups have a minimum circumference equal to the length of the cup wraps. To use each cup wrap, simply peel back and remove a paper liner to expose an aggressively adhesive surface and attach the cup wrap to a paper cup. The secure adhesive attachment to the cup allows the cup wrap to be of a single size, but still fit a wide range of cup sizes. The adhesive attachment quality of these cup wraps make these cup wraps better than other cup holders because other cup holders require the user to fully wrap the cups, but do not attach securely to the cups.
