Abstract
According to one aspect of the present invention, a lubrication box includes a first portion, a shaving aid material, and a second portion. The first portion of the lubrication box has a skin-engaging surface and at least one sidewall that, together, form a cavity. The skin-engaging surface includes at least two holes therethrough. The shaving aid material is pre-formed in a pre-determined shape, placed in the first portion of the lubrication box, and then compressed. The second portion of the lubrication box is attached to the first portion such that the cavity is substantially closed. A gap exists between in the cavity between the shaving aid and the second portion of the lubrication box to permit the shaving aid material to expand during normal use.
