Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a razor head protective cover, and more particularly to at least two razor heads so that the cover can alternately engage the razor upside down without compromising the integrity of the engagement. A protective cover for a razor head having a plurality of devices wherein a mating device is symmetrically disposed about a portion of the cover and removably engages opposing portions of the razor.

[0002]

BACKGROUND OF THE INVENTION One inherent difficulty with high quality razor products that are disposable (ie, a razor head integral with the razor) or reusable (separable from the razor) is associated with normal routine processing. The purpose is to protect the razor blade against damage or cutting. Therefore, it is known to use a protective cover to protect the razor head.

[0003] However, this has been found to have some notable drawbacks when razors are marketed. For example, if the razor is removed from its plastic cover, it will be difficult to use the cover again. This is because thin plastics can deform, collapse, lose, or be disposed of unexpectedly. In addition, thin covers are shaved (soap, hair, excess lubricant), meaning consumers tend to discard the dirty cover and leave the blade unprotected. Similarly, when the razor cartridge comes off the dispenser, the blade remains unprotected and is easily damaged.

[0004] In many razor devices that provide a protective cover, the protective cover is secured to a razor blade cartridge, exposing active parts of the razor such as the razor blade engagement mechanism and the rotating mechanism to become unprotected.
If the razor is misused, for example, if it is dropped or tightly compressed inside the travel bag, the razor is damaged.

[0005] In other known protective covers, the razor and the cover must be properly engaged and oriented upright so that the blades can dry while not in use. Moreover, such protective covers are not mechanically engageable with a razor tray or stand, and consumers may accidentally discard or misplace the cover.

[0006] Some protective covers are adapted to the razor and provide better protection against the engagement and rotation mechanisms. Nevertheless, such covers are easily lost, and consumers consider the cover to be a discarded item (from a disposable item). Consumers, every day,
Or consider that handling the protective cover weekly is inconvenient and not necessary. As a result, protective covers are not required and are easily discarded or incorrectly installed,
The blade is left unprotected in the travel bag when traveling, which has a negative impact on the quality of the blade and razor mechanism, for example, damaging the inside of the travel bag during travel and damaging the hands and fingers.

It would therefore be desirable to be able to provide a protective cover for a disposable or reusable razor that can overcome the aforementioned difficulties and other inconveniences known in the art.

[0008]

SUMMARY OF THE INVENTION The present invention overcomes the disadvantages by providing a permanent use protective cover that can be mounted on a razor and stored in a razor stand while not in use.
