Claims17
A nipple for feeding or drinking bottles, said nipple being made of elastic material with a nipple element for holding in the mouth and a slit arrangement in the area of a front end of the nipple element, in the area of the front end of the nipple element there is a recess which is pointed to the inside, the slit arrangement being located in a bottom section of the recess, wherein the nipple element is flattened to fix one preferred bite direction and the slit arrangement has at least one arc-shaped slit which is closed in an unpressurized state and which opens under pressure in the bite direction, the slit running roughly in the bite direction wherein the nipple further comprises a base body on which the nipple element is adjoining, the base body defining a principal center line and the nipple element extending along a center line, wherein the center line of the nipple element is tilted by an angle α with reference to the principal center line.
A nipple for feeding or drinking bottles, said nipple being made of elastic material and comprising
- a nipple element for holding in the mouth and a slit arrangement in a front end of the nipple element, wherein the nipple element is flattened to fix one preferred bite direction,
- a recess formed in the area of the front end of the nipple element,
- the slit arrangement being located in the recess,
- the recess having a tubular segment which is sealed by a bottom section, wherein the tubular segment is essentially a truncated hollow cylinder with a roughly constant wall thickness, the truncated cylinder extending along an axis inclined with respect to a principal axis of the nipple, one end of the truncated cylinder being defined by the bottom section and the other end of the truncated cylinder being defined by an opening on the front end of the nipple element, wherein the nipple is symmetrical about a main plane of symmetry, and wherein the tubular segment defined in cross section by the main plane of symmetry forms a first, longer jacket side, and an opposing second, shorter jacket side, the height of said second jacket side being less than 3 mm.
A nipple for feeding or drinking bottles, said nipple being made of elastic material and comprising
- a nipple element for holding in the mouth and a slit arrangement in a front end of the nipple element, wherein the nipple element is flattened to fix one preferred bite direction,
- a recess formed in the area of the front end of the nipple element,
- the slit arrangement being located in the recess,
- the recess having a tubular segment which is sealed by a bottom section, wherein the tubular segment is essentially a truncated hollow cylinder with a roughly constant wall thickness, the truncated cylinder extending along an axis inclined with respect to a principal axis of the nipple, one end of the truncated cylinder being defined by the bottom section and the other end of the truncated cylinder being defined by an opening on the front end of the nipple element, wherein the nipple is symmetrical about a plane of symmetry, wherein a cross section of the tubular segment taken on said plane of symmetry has a longer jacket side and a shorter jacket side, and wherein the bottom section in the area of the shorter jacket side is molded directly to the flattened top of the nipple element.
A nipple for feeding or drinking bottles, said nipple being made of elastic material with a base body and a nipple element for holding in the mouth adjoining the base body, the base body defining a principal center line and the nipple element extending along a center line, and a slit arrangement in the area of the front end of the nipple element, where the nipple element is flattened to fix one preferred bite direction, in the area of the front end of the nipple element there is a recess which is pointed to the inside, the slit arrangement being located in the recess, wherein the center line of the nipple element is tilted at an angle α relative to the principal center line and wherein the recess has a bottom section which is bent relative to the center line of the nipple element such that there is a tilt angle β0 between 30° and 80°.
