Oral Hygiene Implement
First Claim
1. An oral hygiene implement comprising:
- a neck section extending along a longitudinal direction and having a neck section housing surrounding a neck section cavity;
a head section having a through hole therein extending through the head section along a through hole direction having an angle with respect to the longitudinal direction and having a head section housing surrounding the through hole;
wherein the through hole defines a first and a second opening in the head section housing; and
wherein a cap element separately made from the head section housing is connected with the head section housing to essentially cover the first opening and a carrier element separately made from the head section housing is arranged to essentially cover the second opening, andwherein there is a circumferential gap extending between an edge of the first opening and an edge of the cap element, the circumferential gap being structured and configured to allow water, saliva, or toothpaste to escape an interior of the head section.

Abstract
An oral hygiene implement has a neck section extending along a longitudinal direction and a head section having a through hole therein extending through the head section along a through hole direction having an angle with respect to the longitudinal direction and having a head section housing surrounding the through hole. The neck section has a neck section housing surrounding a neck section cavity. The through hole defines a first and a second opening in the head section housing. A cap element, separately made from the head section housing, is connected with the head section housing to essentially cover the first opening. A carrier element, separately made from the head section housing, is arranged to cover the second opening. Between an edge of the first opening and an edge of the cap there is a circumferential gap that allows water, saliva, or toothpaste to escape an interior of the head section during use.

18. A method of manufacturing an oral hygiene implement comprising a neck section extending along a longitudinal direction and having a neck section housing surrounding a neck section cavity;
- a head section having a through hole therein extending through the head section along a through hole direction having an angle with respect to the longitudinal direction and having a head section housing surrounding the through hole, the method comprising the steps of;
providing a first mold plate defining at least parts of an outer side of the neck section housing and of the head section housing, the first mold plate comprising at least a first shaping projection; providing a second mold plate defining at least parts of the outer side of the neck section housing and of the head section housing, the second mold plate comprising at least a second shaping projection; providing a core defining at least parts of an inner side of the neck section housing and of the head section housing, the core comprising a shaping front portion, wherein the core has a depression at its shaping front portion that defines a first projection radially extending from the inner side of the head section housing into the through hole; moving the first mold plate, the second mold plate, and the core together so that the first shaping projection, the second shaping projection, and the shaping front portion define the inner side of a through hole through the head section housing having a first opening and a second opening, wherein the shaping front portion defines at least a portion of the inner side of the head section housing distal to the neck section; and injecting a plastic material into the mold cavity. - View Dependent Claims (19, 20, 21)
