    • An artificial nipple can include a nipple body portion connected to a mounting structure that is configured for mounting the nipple on an infant feeding bottle 11. A mammary papilla leading end portion 140 can be disposed at the leading end portion of a mammary papilla portion 130 and have a leading end opening portion 141. The wall from the nipple body portion to the mammary papilla leading end portion is made of a soft material. The inner layer on the inner side of the wall is formed of a shape holding layer made of a material having a rigidity capable of holding the wall shape. The outer layer on the surface side of the wall is formed of a tongue abutting layer having a smooth face for allowing a peristalsis motion by a tongue. Between the shape holding layer and the tongue abutting layer there is disposed a deformation absorbing layer which is made of a material having a lower rigidity than that of the material of the shape holding layer and the tongue abutting layer. The deformation absorbing layer can be made thicker than the shape holding layer and the tongue abutting layer.
    • 人造乳头可以包括连接到安装结构的乳头主体部分,其被配置为将乳头安装在婴儿喂养瓶11上。 乳房乳头前端部140可以设置在乳头乳头部130的前端部,并且具有前端开口部141。 从乳头主体部分到乳房乳头前端部的壁由软质材料制成。 壁内侧的内层由具有能够保持壁形状的刚性的材料形成的形状保持层形成。 壁的表面侧的外层由具有平滑面的舌接触层形成,用于允许舌头的蠕动运动。 在形状保持层和舌片抵接层之间设置变形吸收层,该变形吸收层由具有比形状保持层和舌接触层的材料刚性低的材料制成。 变形吸收层可以形成为比形状保持层和舌片抵接层更厚。
