US Patent 9486066 Manual toothbrush concept being combined from three parts

A toothbrush comprises a head, a neck portion and a handle, wherein the neck portion and the handle portion are connected to one another via a coupling element. The connection is constructed as an inseparable connection, i.e., after being combined once, the neck portion and the handle cannot be separated without the brush being destroyed by such separation. A method for producing such a toothbrush may comprise the following steps: providing a head, a neck portion, a handle, and a coupling element, and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed.
