  • Patent number: 8690263
    Abstract: A molding process and a mold for manufacturing a toothbrush of plastic material with a resistant inner core, is disclosed. It is provided to manufacture a resistant inner core, and to introduce it into a mold cavity having opposite footprints belonging to a lower half-mold and an upper half-mold and to subsequently inject molten plastic material into the mold cavity for manufacturing at least part of the toothbrush handle. A resistant metal core is placed into a respective footprint of the lower half-mold in contact with at least two support platforms, adapted to support the core in the proximity of a central line of the mold cavity, and before the injection of structural plastic material, to couple the lower half-mold with an upper half-mold having at least one ribbing to contact with the metal core at least in a position between the support platforms and in a position opposite thereto.

  • Patent number: 8448287
    Abstract: A toothbrush with a replaceable head formed to permit ready removal and attachment preferably without the use of a tool. The replaceable toothbrush head may advantageously be formed for coupling with a power toothbrush, particularly, a power toothbrush with a power element that protrudes from the toothbrush head. The replaceable toothbrush head thus preferably is formed to accommodate the power element. In a preferred embodiment, the replaceable toothbrush head is rotated about a rotation axis into engagement with the head of the toothbrush main unit. The replaceable toothbrush head may be moved axially along the rotation axis for alignment with an alignment axis. Preferably, the replaceable toothbrush head is moved axially into engagement with the power element for alignment for coupling with the toothbrush main unit.
