摘要:
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. A mammary papilla leading end portion can be disposed at the leading end portion of a mammary papilla portion and have a leading end opening portion. 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. 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.
摘要:
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.

A subdividing apparatus for use in an cut tobacco expanding system comprises a primary de-clumper arranged to receive a tobacco cake of impregnated cut tobacco taken out of an impregnation container and subdivide the received tobacco cake into tobacco loaves, and a secondary de-clumper arranged to receive the tobacco loaves from the primary de-clumper, subdivide the received tobacco loaves first into tobacco chunks and then further subdivide the tobacco chunks into tobacco lumps. The secondary de-clumper includes paired rotary rakes and a rotatable drum rake 26 located below the rotary rakes.

A flash dryer of cut tobacco comprises a drying duct (16) for connecting a feeding section (14) of cut tobacco to a tangential separator (18). The drying duct (16) has an upstream-side duct portion (16a) extending straight from the feeding section (14) at an elevation angle ranging from 30° to 60° and a downstream-side duct portion (16b) curving upward in a convex shape. A dry gas that flows through the drying duct (16) may contain superheated steam.
