An injection-molded first component of an article, the first component including a sheath element formed from a pre-sheath element, the sheath element having a cavity and a recess extending from the cavity into a wall of the sheath element surrounding the cavity. The recess is formed by a through hole in the pre-sheath element and a lid element closing the through hole. The lid element is connected to the pre-sheath element with a plastic material injection-molded over at least a part of a parting line between the lid element and the pre-sheath element.

A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.

Head for an oral care implement

An oral care implement comprises a head and a handle, the head having a length extension and the handle having a length extension, the length extension of the head and the handle together defining an overall length extension of the oral care implement along a longitudinal axis. The overall length extension of the oral care implement is from about 194 mm to about 197 mm and the ratio of the length extension of the handle to the overall length extension of the oral care implement is from about 0.59 to about 0.65.

Oral care implement and method for manufacturing such oral care implement

An oral-care implement comprises a carrier plate and a support plate. Each of the carrier plate and the support plate has a back side and a front side opposite the back side. At least one cleaning element extends from the front side of the carrier plate. The back side of the carrier plate is secured to the front side of the support plate with a plastic material that is molded around at least a portion of the back side of the support plate and over at least a portion of the carrier and that fills a channel formed by a recess in at least one of the back side of the carrier plate and the front side of the support plate, thereby providing a non-detachable connection between the carrier plate and the support plate.

An oral care implement comprises a head and a handle made of a first material. The handle has a distal end and a proximal end closest to the head. The handle comprises a thumb rest made of a second material, the second material being different from the first material. The thumb rest comprises an area from about 202 mmto about 360 mmand has a concave shape. The thumb rest comprises a portion being inclined with respect to a remaining portion of the thumb rest by an angle &#x3b1; of about 20&#xb0; to about 25&#xb0;, the angle &#x3b1; being defined by a first line and a second line. The first line extends between a most elevated point and a lowest point of the thumb rest, and the second line extends between the lowest point and an end point of the thumb rest, the end point of the thumb rest being closest to the distal end of the handle.

Toothbrush head

An injection-molding process and an apparatus for making a multi-component hollow article, and the article made thereby. The process comprises molding, from a first plastic material, a hollow body having a wall with at least one vent therethrough and at least one flap molded in an area adjacent to the vent. The flap is molded in a first position in which the vent is open. The flap is hingedly movable from the first position to a second position in which the vent is closed by the flap. After the flap is folded into the second position, the hollow body, including the folded flap, is at least partially overmolded with a second plastic material, wherein the second material is essentially precluded from leaking into the hollow body through the vent. The apparatus comprises a first mold bar for molding a hollow body, a second mold bar for overmolding the hollow body with a second plastic material, and a closing tool for moving, and optionally retaining, the flap in the second position. The resulting article has no second material inside its hollow body.
