An accessory for a flexible toothbrush that is “prison-safe” and also lightweight and compact and therefore ideal for travel is disclosed. More particularly, the invention comprises a toothbrush cover that is made from flexible material having elastic properties so that the cover can deform and fit around the toothbrush, then subsequently return to its original shape.
1. Field of the Invention
The present invention pertains generally to toothbrush devices and accessories in addition to inmate-safe hygiene products for the correctional services market. More specifically, the present invention relates to inmate hygiene products having safety features to prevent the product from being used to cause harm to individuals. The present invention is particularly, but not exclusively, useful as a flexible inmate-safe toothbrush cover.
2. Description of the Prior Art
Regular brushing of teeth is considered paramount to healthy oral hygiene and prevention of tooth decay. The American Dental Association (ADA) recommends individuals brush their teeth at least twice a day to remove decay-causing plaque and tarter as protection against developing cavities, gingivitis and gum disease. Moreover, in 2003 the toothbrush was recognized as the number one invention Americans could not live without beating out the automobile, computer, cell phone, and microwave oven according to the Lemelson-MIT Invention index. Toothbrush covering devices are additionally important to keep toothbrushes clean and free of bacteria between uses.
Heretofore, toothbrush covering devices have been well known in the art as early as the invention described in TOOTHBRUSH HOLDER, U.S. Pat. No. 2,956,851 to Merendino issued in 1960. Numerous other examples exist and while these devices fulfill their respective objectives, there remains a need for novel hygiene products specifically designed for the correctional services market while also having attractive features applicable to the overall retail toothbrush market.
Prisons and other detention systems monitor devices permitted to be used by inmates to prevent the use of an otherwise safe device as a weapon. For example, conventional toothbrushes and toothbrush containers are not permitted to be used by many prison systems because they may be fashioned into a pointed shaft or rod or otherwise used as a shank for a sharp object such as a razor blade, which could be used to endanger inmates as well as other security personnel. Similarly, toothbrush covers made of rigid plastic could also be forged into sharp objects. Also, some toothbrush covers could be used by inmates to throw urine or chemicals at guards or other inmates or to pass illegal substances such as powdered drugs between inmates.
Present inventor Kayser and assignee of the present invention, Loops, LLC have proposed other hygiene products with applicability to the correctional market such as TOOTHBRUSH AND METHODS OF MAKING AND USING SAME, U.S. Pat. No. 7,334,286, U.S. Pat. App. Pub. No. 2007/0226931, U.S. Pat. App. Pub. No. 2006/0037160; PACKAGED TOOTHBRUSH AND TOOTHBRUSH CONTAINER AND METHODS OF MAKING SAME, U.S. Pat. App. Pub. No. 2007/0119736; and METHOD OF USING DENTAL FLOSS, U.S. Pat. App. Pub. No. 2005/0257801. As stated herein, additional hygiene products are needed in the market.
In light of the situation described herein, it is an object of the present invention to provide a Toothbrush Cover that is a secure fit to existing toothbrushes on the correctional market. It is another object of the present invention to provide a cover for a toothbrush that is made of relatively soft, lightweight flexible material that can not be easily fashioned into a weapon. It is still another object of the present invention to provide a toothbrush cover that will not retain liquid that may be used by inmates for purposes other than for covering a toothbrush. It is yet still another object of the present invention to provide a toothbrush cover configured for existing toothbrushes that is well suited for travelers or backpackers because of its small size and light weight. It is still further an object of the present invention to provide a toothbrush cover with simple retention means.
BRIEF SUMMARY OF THE INVENTIONThe present invention specifically addresses and alleviates the above mentioned deficiencies associated with the prior art. More particularly, the present invention in a first aspect is a cover for a toothbrush for preventing bacteria and contaminants from depositing on the toothbrush while not in use, the cover comprising: a base portion for securely fitting over and around a toothbrush head; an upper portion for fitting over and protecting toothbrush bristles; and a pair of retaining ribs to secure the head of the toothbrush to the cover.
The invention is further characterized in that the base portion has an inside width, also the corresponding toothbrush head has a width, the toothbrush head width greater than the base portion inside width, wherein the base portion can elastically deform and subsequently retain its original shape so that the base portion is able to fit around the toothbrush head and secure the toothbrush head. As an alternative to retaining ribs, the inner wall has a shape to matingly receive a shape of the toothbrush head. Yet further, the invention comprises vent holes to allow for some fresh air flow to the device while in use, and also to prevent the device from being able to hold liquids, for example, in the correctional environment. More specifically, vent holes are located on an end of the cover, on a bottom of the base portion, and on top of the upper portion. Yet still further, an air gap between the upper portion and the toothbrush bristles further assists ventilation of the device.
The cover of the present invention comprises flexible material that is not easily forged into a device that could be used as a weapon. The invention further comprises a length, the length approximately in the range of 1⅜ inches to 1½ inches.
It is further contemplated that the invention be made from transparent or semi-transparent material.
