Abstract: A brush holder includes a generally cylindrical container with an inner annular flange close to its open end and a raised brush support which defines a lower liquid reservoir. The annular flange is preferably inclined toward the bottom of the container or, alternatively, is perforated. The dimensions of the annular flange are chosen such that when a brush is inserted into the container and removed from the container, the flange squeezes the brush. As the brush is squeezed, liquid is removed from the brush and drips into the liquid reservoir. The brush support is preferably a raised central portion of the container floor which defines an annular reservoir or, alternatively, the brush support may be formed as a perforated disk which is spaced above the floor of the container. The brush support keeps the brush out of the reservoir so that the brush will remain dry.

Abstract: A novel toothbrush staple for a holding a U shaped tuft of bristles in a tuft hole of a toothbrush head. The staple is generally flat and its lower edge is rounded to inhibit rupturing the bristles at the bight portion of a U shaped tuft of bristles mounted by the staple in the hole. The sides of the staple are provided with one or more horizontal grooves each having a sharp edge. The arrangement of tufts and staple is such that the rounded bottom of the staple contacts the bight portion of the tuft of bristles, thus precluding rupture due to sharp edges at the staple bottom bearing against the bight portion of the tufts, especially during initial installation of the tuft in the hole. Each leg of the U shaped tuft is in contact with a respective staple surface. With the passage of time, plastic creep or flow results in the plastic on the inside wall of the hole flowing towards the staple sides and interlocking with the sharp edges of the grooves.
