Abstract

A razor that facilitates a user's removal of shaving lubricant, cut hairs, and other shaving-related debris, from around, and between, the razor's blade(s). A scoop at the upper portion of the razor's blade assembly funnels water to the blade channel in which the blades are affixed, and at least a portion of that water flows around and/or over the blade(s). The scoop captures, and directs through the razor's blades, a greater volume of water per unit time than can be achieved with an unmodified blade assembly. The cross-sectional area of the scoop's inflow mouth is greater than that of the blade channel's outflow mouth, thereby promoting a Venturi effect which increases the speed of the water's flow over the blades.

Claims (12)

1. A razor cartridge comprising:

first and second opposed trough walls partially defining an inlet, and an outer edge of the first and second trough walls partially defining an open end of the inlet;

third and fourth opposed walls partially defining an opening;

an inner edge of the first and second trough walls being coincident with an inner edge of a respective one of the third and fourth walls, thereby defining communication between the opening and the inlet;

a plurality of spaced blades defining gaps retained in the opening; and

wherein a liquid is able to be received in the open end of the inlet and travel unobstructed through the inlet to the opening and pass through the gaps defined by the blades.

2. The razor cartridge of claim 1 , wherein at least one of the first and second opposed trough walls have a concave profile.

3. The razor cartridge of claim 2 , wherein the third and fourth walls have a straight profile.

4. The razor cartridge of claim 2 , wherein the outer edge of the first trough wall extends away from the opening at a greater distance than the outer edge of the second trough extends away from the opening.

5. The razor cartridge of claim 4 , wherein each of the blades has a cutting edge that is angled towards the second trough wall.

6. The razor cartridge of claim 1 , wherein both the first and second opposed trough walls have a concave profile.

7. The razor cartridge of claim 1 , wherein the first trough wall and second wall are asymmetric.
