Artificial nipple and a feeding bottle having the artificial nipple

An artificial nipple comprising:

• a nipple portion having a first curved surface, whose tip is provided with an opening portion;
• a nipple body portion formed on the nipple portion, having a second curved surface, wherein the second curved surface of the nipple body portion is continuously extended from the first curved surface of the nipple portion, and wherein the second curved surface of the nipple body portion is significantly expanded as a part of the second curved surface goes away from the nipple portion;
• and
• a base portion formed on the nipple body portion, wherein the base portion is capable of being attached to a container to house a drink,
• wherein the nipple body portion has a maximum outer diameter of 30 mm or more, and
• wherein the nipple portion is composed of an elastic material having a Durometer A hardness of 5 to 25, and
• wherein the nipple portion has a thickness in the direction of the center thereof, at the maximum outer diameter portion of the nipple portion, of 1.5 mm or more.

A feeding bottle comprising:

• a container to house a drink;
• an artificial nipple attached to the container;
• the artificial nipple comprising:
• a nipple portion having a first curved surface, whose tip is provided with an opening portion;
• a nipple body portion formed on the nipple portion, having a second curved surface, wherein the second curved surface of the nipple body portion is continuously extended from the first curved surface of the nipple portion, and wherein the second curved surface of the nipple body portion is significantly expanded as a part of the second curved surface goes away from the nipple portion;
• and
• a base portion formed on the nipple body portion, wherein the base portion is attached to the container to house a drink,
• wherein the nipple body portion has a maximum outer diameter of 30 mm or more,
• wherein the nipple portion is composed of an elastic material having an elasticity of 0.1 N to 0.8 N at the time when the maximum outer diameter of the nipple portion is compressed by 20%, and of 1.0N to 2.5N at the time when the maximum outer diameter of the nipple portion is compressed by 60%,
• wherein the nipple portion is measured by placing the base portion of the artificial nipple on a precise universal tester having a metallic pressing top made of a cylindrical shape with a radius of about 5 mm, to compress the maximum outer diameter of the nipple portion into the direction of the center thereof;
• and
• a fixing portion for fixing the artificial nipple at the container.
