Description
- The present invention relates to a disposable shaving device with razor blade of the type used in barbershops and by hairdressers. The present invention relates to a disposable straight razor having two or three razor blades for use in barber shops and by hairdressers.
- 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 Patents US 4,622,742 (Lee), US 4,920,644 (LaGattuta) and US 5,649,364 (Ilanlou).
- In DE 27 21 421 A1, there is disclosed a straight razor with a single razor blade which is interchangeably mounted in an elongate body. The straight razor further comprises a cover for covering the blade and a part of the body, which cover is pivotally connected to said body and serves as handle when the straight razor is in use.
- An object or feature of the present invention is to provide a disposable straight razor having two or three blades for shaving, which is light weight and easy to use in barber shops and by hairdressers.
- Another object or feature of the present invention is to provide a disposable straight razor having a body molded about two or three razor blades for shaving with a highly safety factor that ensures non transmission of diseases and microbes from one infected person to another healthy person together with a smooth shave in an easy and safe manner.
- Another object of the invention is to provide a disposable straight razor having two or three razor blades fixed in a body, which does not need blade replacement or changing and accordingly does not need to be touched by the user, whereby infections are not transmitted to the user himself.
- According to a first aspect of the present invention, there is provided a disposable straight razor comprising an elongate body, a razor blade assembly mounted in said body and extending outwardly from said body and a cover for the body and the razor blade assembly, which extends over said body and completely over said razor blade assembly. The body is molded about said razor blade assembly and said razor blade assembly is a double razor blade and projects above the upper edge of said body by approximately 0.5 mm to 4.00 mm, preferably between 1-2 mm. The higher or upper blade of the blade assembly projects between approx. 0.5 mm to 2.00 mm above the lower, outer blade and the lateral distance between the blades is in the range of about 0.5 mm and 2.00 mm and is maintained by spacing material.
- A second aspect of the present invention concerns a disposable straight razor comprising an elongate body, a razor blade assembly mounted in said body and extending outwardly from said body and a cover for said body and said razor blade assembly, which extends over said body and completely over said razor blade assembly. The body is molded about said razor blade assembly and said razor blade assembly is a triple razor blade and projects above an upper edge of said body by approximately 0.5 mm to approximately 4 mm, preferably between 1 and 2 mm.
