Description
- This application claims the benefit of U.S. Provisional Patent Application entitled Brush and Toss having No. 63/101,411 filed Apr. 30, 2020, the entirety of which is hereby incorporated by reference.
- The invention relates in general to a toothbrush, particularly a toothbrush providing an integrated cavity for storing and dispensing toothpaste.
- A toothbrush is an oral hygiene instrument used to clean dental surfaces including teeth, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth.
- They are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard-bristled toothbrushes can damage tooth enamel and irritate the gums.
- Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis). Salt and sodium bicarbonate (baking soda) are among materials that can be substituted for commercial toothpaste.
- Currently, toothbrushes and tubes of toothpaste are purchased and maintained separately. Particularly while traveling, it can be a hassle to transport and organize a toiletry bag. For example, a toothbrush and associated tube of toothpaste, which can be irregular in shape and bulky, take up much needed space in a toiletry bag. Further, it can be extremely difficult to quickly find, among all of the other items submerged in a bag, both the toothbrush and the tube of toothpaste. Put simply, time and space are limited and people who like to travel gravitate towards personal items that are small, compact and easy to fine.
