Oral care implement and handle and refill head thereof
First Claim
1. An oral care implement handle comprising:
- a gripping portion extending from a proximal end to a distal end;
a stem comprising an attachment portion protruding from a first transverse shoulder at the distal end of the gripping portion, the stem extending along a stem axis and configured to be detachably coupled to a replaceable oral care device, the attachment portion of the stem comprising;
a second transverse shoulder axially spaced from the first transverse shoulder; and
a post protruding from the second transverse shoulder, the post terminating in a closed distal end that forms a free end of the attachment portion of the stem, the post comprising a hub portion extending along the stem axis and at least one protuberance protruding (1) radially from a side surface of the hub portion; and
(2) upward from the second transverse shoulder; and
a vibration generating device;
wherein the at least one protuberance comprises a rib that protrudes radially from the side surface of the hub portion and upward from the second transverse shoulder.

Abstract
An oral care implement handle or a refill head therefor. The oral care implement handle may include a gripping portion and a stem protruding from a shoulder of the gripping portion. The stem may include a post located at a distal end of the stem. The post may have a non-circular transverse profile. More specifically, the post may include a hub portion and a protuberance that either protrudes radially from a side surface of the hub portion, protrudes upward from the shoulder of the gripping portion, or both. The refill head may include a sleeve having an inner surface that defines an internal cavity. The internal cavity may include a central portion and at least one slot portion extending radially from the central portion. Thus, the internal cavity of the sleeve portion may have a profile configured to receive the stem of the oral care implement handle.
