Claims12
An oral hygiene device, comprising:
- at least one application unit having a first base body;
- at least one handle unit having a second base body;
- and
- at least one coupling unit separating the application unit and the handle unit from each other and for releasably coupling the application unit to the handle unit,
- wherein the at least one coupling unit has a first coupling element and a second coupling element,
- wherein the second base body has a hardness and/or a density that is greater than a hardness and/or density of the first base body,
- wherein at least the second base body has at least 90% by volume of a metallic material,
- wherein the first coupling element is formed integrally with the application unit,
- wherein the second coupling element corresponds to the first coupling element and is fixedly connected to the handle unit, and
- wherein the second coupling element of the coupling unit is made at least largely of plastic and is connected to the handle unit at least by form fit and/or substance bonding.
