Benefits of technology

This patent describes a toothbrush made of a solid handle made of a combination of biodegradable cornstarch and recycled polypropylene. The weight ratio of cornstarch to polypropylene can be from 50:50 to 80:20. By using this composition, the toothbrush is made in a more environmentally friendly way and can be easily disposed of. The technical effect of this invention is to provide a more eco-friendly toothbrush that is convenient and easy to use.

Problems solved by technology

Conventional toothbrushes have a negative impact on the environment.
In addition to excessive landfill use, the use of conventional toothbrushes can lead to (i) damage to the atmosphere upon burning, and (ii) destruction of trees, a significant factor in that a mature tree removes approximately 48 pounds of CO2 from the atmosphere per year.

Embodiment Construction

[0010]In the present invention, it has now been found that a non-disposable toothbrush can be constructed using environmentally friendly material such that the handle retains the physical features desirable in a toothbrush.

[0011]The growing environmental burden caused by conventional toothbrush use is directly addressed by the subject invention, namely, an “Eco Safe” environmentally friendly toothbrush. These toothbrushes are made entirely of recycled material and / or material from a renewable source that can be completely recycled. When the toothbrush has completed its usable lifecycle, it can be returned to the manufacturer or seller, where the components can then be separated and recycled.

[0012]These toothbrushes made from biodegradable and recycled materials have numerous advantages, such as the following: (i) the toothbrushes are made with biodegradable materials, and thus use less landfill space than conventional toothbrushes; (ii) toothbrushes made with recycled materials reus...

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 237,075, filed Aug. 26, 2009, and U.S. Provisional Application No. 61 / 263,189, filed Nov. 20, 2009, the contents of both of these applications being incorporated herein by reference.[0002]Throughout this application, various publications are cited. The disclosure of these publications is hereby incorporated by reference into this application to describe more fully the state of the art to which this invention pertains.BACKGROUND OF THE INVENTION[0003]Conventional toothbrushes have a negative impact on the environment. For example, more than 50,000,000 pounds of toothbrushes pile up in landfills in this country annually. On an individual basis, a person who lives to be 80 years of age and follows his dentist's advice to change toothbrushes every three months, which is also the interval recommended by the American Dental Association, will use more than 300 brushes in his lifetime.[0004]In addition to exces...
