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.

Abstract: A replaceable-head, dental care tool is disclosed, of the type including a handle element (1) and a tool element, the tool element including an engaging extension (10) having at least one flexible reed element (11) equipped with an end pawl (12), and the handle element comprising an engagement seat (2) for the engaging extension (10) which has a shoulder (2b?) able to retain the pawl (12), as well as an activation button (5) in the shape of a separate button and capable of pushing on the pawl (12) to disengage it from the shoulder (2b?), the seat (2) being externally surrounded by an edge (4) of soft elastic material wherein the button (5) is circumferentially enclosed.

Abstract: The present invention relates to a supporting device for an interdental cleaning means, of the type comprising a handle and a tightening head for an elongated appendix portion of said cleaning means, said tightening head comprising a central body around which a complementary rotating bush is mounted, and wherein said bush and said central body have a common hole for hosting said appendix portion, which hole is substantially parallel and offset relative to the rotation axis of the bush.

Abstract: A disassemblable toothbrush, includes a bristled portion and a handle portion, the bristled portion comprising a coupling part having at least one flexible working portion provided with a tooth and the handle portion comprising a seat for engagement of the coupling part which has at least one locating element for retaining the tooth, in which the engaging seat (4) comprises a recess (4b) for housing a deformable elastomeric mass (E) able to exert an elastic reaction pressing against the flexible working portion of the coupling part so as to keep the tooth (3c) actively engaged with the locating element (6).

Abstract: An interdental tooth-brush includes a support bar (1) with a transversal hole (2a) at one end, a small brush stick (3) with a filiform projection (3a) apt to engage into the transversal hole (2a), and a retention device to fix the projection (3a) into the transversal hole (2a) in an interchangeable manner. The transversal hole (2a) is formed into a support head (2) provided at the end of the support bar (1). This support head (2) has a protuberance projecting through a slot (4a) of a cap (4) fitted onto the support head (2). The cap (4), having two diametrically opposite slots (4a, 4b), is axially slidable between a position of release, in which both slots (4a, 4b) are aligned with the transversal hole (2a), and a locking position, in which the rear slot (4b) is axially offset with respect to the hole (2a ).
