2. Discussion of the Prior Art
There are numerous ice scrappers in the art. One example of an ice scrapper with a de-icing dispenser is U.S. Pat. No. 6,283,656 to Jiang, entitled handheld windshield de-icer. The Jiang patent includes a hand operated de-icer for cleaning ice and snow from a windshield of a vehicle including a sprayer that forces an antifreeze liquid from its bottle through a heated nozzle onto the windshield. However, the user must connect the handheld windshield de-icer to a cigarette lighter of a vehicle, which makes its use and maneuverability difficult.
Accordingly, there is a clearly felt need in the art for de-icing scrappers, which not only scrape ice, but dispense a de-icing fluid on to an ice covered windshield to decrease the amount time and labor required to remove the ice.
The present invention provides de-icing scrapers, which scrap ice and dispense a de-icing liquid. A de-icing scraper preferably includes a scraper member, a handle member, a trigger device and a pressurized de-icing cartridge. The scraper member includes a scraper portion and a handle portion that extends from the scraper portion. An end of the handle portion preferably includes a threaded end.
