This weeks, we will be discussing nine different patents that all relate to the applications of cups and sleeves. With regards to these patents, will be taking a deeper look into their background, priority date, technology, diagrams, and claims.
Patent 1: US 6343735 B1 Insulating sleeve
The priority date of this patent is May 4th, 2000. This sleeve helps people protect themselves from burning their hands and additionally helps the environment by reducing the number of people who utilize two coffee cups to protect themselves from the heat. Foam is also a cheaper material to produce. Specifically to prevent heat transfer, air gaps and cardboard boxes (two-sided) help allow for the success of this sleeve.
Patent 2: US 2661889 A Thermal coffee cup
The priority date of this patent is July 20th, 1948. The thermal coffee cup helps prevent burning of the hands by covering the cup's outer layer of cup. Heat is insulated and portability is made much easier with this thermal coffee cup's inner and outer lining (outer lining helps keep the cup and lid together.
Patent 3: US 8,251,277 B1 Thermal sleeve, method for manufacturing a thermal sleeve, and combination cup and thermal sleeve
The priority date of this patent is April 15th, 2005. The thermal sleeve and its method for manufacturing a thermal sleeve allows hot beverages to be insulated and allows consumers to be protected from the heat. Burning is prevented, and the additional claims elaborate on the sleeve's paper material. The paper on the sleeve has an adhesive to allow for the ends to keep together and wrap around different sized cups.
Patent 4: US 7,922,031 B1 Insulator sleeve for a beverage container
The priority date of this patent is March 1st, 2006. This sleeve's design is tailored mainly for reusable cups due to the fact that the sleeve is also reusable. Consumers can more easily grip this sleeve due to the unique texture and the mixture of vinyl and rubber in the sleeve.
Patent 5: US 8118189 B1 Temperature-indicating sleeve and related container
The priority date of this patent is December 15th, 2006. This sleeve allows for the temperature within the cup to be indicated to the consumer. Normal sleeves completely block the temperature, but this sleeve allows a reasonable amount of heat to reach the consumer, so that one can determine how if a beverage is hot or cold. The temperature indication also allows consumers to easily see the temperature of the beverage.
Patent 6: US 6152363 Sleeve construction for improved paperboard cup insulation
The priority date of this patent is May 3rd, 1999. Air gaps with hot-melt glue dots, a top convex edge, and a bottom concave edge allows for consumers to be protected from the cup's heat. Recyclable paper is definitely an option with this sleeve, and the air gaps definitely allow for optimal insulation.
Patent 7: US 20080078824 A1 Beverage cup sleeving system and method
The priority date of this patent is August 23rd, 2006. Although this patent is unoriginal, the unique aspect of it comes with its ability to reduce costs. Furthermore, the technology allows for two layers which allows for some exposure to liquid with minimal damage. Normally, moisture could ruin a sleeve, but this sleeve prevents consumers from using two sleeves in order to prevent liquid damage.
Patent 8: US 20100019023 A1 Protective sleeve
The priority date of this patent is June 25th, 2008. This sleeve allows for consumers to be more comfortable when holding cups, and also utilizes the elastomer material. This material allows for less waster in the environment, and is also biodegradable. Elastomer produces paper materials that are also biodegradable.
Patent 9: US 20140151385 A1 Hot and Cold Cup Sleeve
The priority date of this patent is February 6th, 2014. This sleeve protects consumers from both hot and cold beverages. The inner lining of this sleeve allows for water absorption, and the outer lining acts as a water repellent. This is especially important because of condensation from old beverages. The sleeve is disposable and actually encompasses three layers.
I hope this post allowed for a comprehensive understanding of patents for cup sleeves! Looking forward to reading your comments!
