An oral care implement with a soft tissue cleaner. The oral care implement may include a handle and a head, the head having a first surface, and an opposite second surface, and a peripheral surface extending between the first and second surfaces. A soft tissue cleaner may have a first cleaner fixed to the second surface of the head and a second cleaner fixed to the peripheral surface of the head. Furthermore, a second cleaner may incorporate a plurality of grooves extending at least a portion of the distance from the first surface to the second surface along the peripheral surface.

An oral care implement with a soft tissue cleanser. The oral care implement may include a handle and a head, the head having a first surface and an opposite second surface. A first cleanser may be fixed to the first surface of the head such that the first cleanser has a hole through which a portion of the first surface of the head is exposed. Furthermore, a second cleanser may be fixed to the portion of the first surface of the head that is exposed through the hole of the first cleanser.

An injection molding machine includes a machine base extending lengthwise along a machine axis. The base has a platen support portion extending along a first axial portion of the base, and an injection unit support portion extending along a second axial portion of the base. The machine further includes a platen supported by the platen support portion for carrying a mold half apparatus. The machine further includes a first injection unit supported by the injection unit support portion for discharging a first melt through the platen into a first mold inlet of the mold half apparatus, and a second injection unit supported by the injection unit support portion for discharging a second melt around the platen into a second mold inlet of the mold half apparatus.
