ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention.
The present invention relates to a disposable shaving device with razor blade of the type used in barbershops and by hairdressers. More specifically, the present invention relates to a disposable straight razor having a cover and a razor blade extending outwardly from a body of the straight razor a distance between approximately 0.5 and 4 mm.
2. Description of the Prior art
Presently available shaving devices and razor blades used therein typically include a body and a razor blade which is periodically changed while keeping the body of the device for further use.
The shaving device of this type is exposed to various contamination factors during the process of changing blades such as may result from any wounds that might have taken place during the prior shaving use.
This can lead to the contamination of the shaving device per se, which in turn can cause infection and may cause the transfer of different diseases from one infected person to another healthy person. Infections are now very serious and include skin diseases in addition to the more serious diseases, which are carried by skin and blood, such as staphococus, hepatitis Virus B and C and AIDS.
Heretofore, several disposable straight razors have been proposed and examples of same are disclosed in the following U.S. Patents:

SUMMARY OF THE INVENTION
An object or feature of the present invention is to provide a disposable shaving device with razor blade, such as a straight razor, which is lightweight and easy to use in barber shops and by hairdressers.
Another object or feature of the present invention is to provide a disposable device with razor blade for shaving which has a high degree of safety to ensure non transmission of diseases and microbes from one infected person to another healthy person while at the same time providing a high performance razor blade useable in an easy and safe manner.
Still another object or feature of the present invention is to provide a shaving device with a razor blade that does not need razor blade replacement or changing and accordingly does not need to be touched by the user and thus preventing infections from being transmitted to the user or others.
According to the teachings of the present invention there is provided a disposable straight razor comprising: an elongate body; a razor blade mounted in the body; the body being molded about the razor blade; the razor blade extending outwardly from the body a distance of from approximately 0.05 mm to approximately 4 mm; and a cover for the body and the razor blade which extends completely over the body and the razor blade.
