２から乳頭部側Ａ２へ入る。Inside the nipple A, the nipple side A1 and the connecting part side A2 are separated by a check valve 5 provided in the middle of the trunk 2. In this check valve 5, a slit 52 having a longitudinal length of about 0.5 to 5 mm is formed in the center of a circular partition wall 51. This slit 52 has two opposing circular arc surfaces 52a, and the width gradually becomes narrower toward both ends. The periphery of the check valve 5 is moved in a direction perpendicular to the longitudinal direction of the slit 52 (
When compressed in the direction shown by the arrow X in Figure 2), the slit 5
2 is occluded (see Figure 3). Furthermore, when the compression is released, the slit 52 is opened and the beverage is released from the baby bottle side A.

Alternatively, when the contracted teat side A1 restores to its original shape, the beverage can be introduced from the connection side A2 to the teat side A1, and the distribution of the beverage can be controlled by biting the teat side AI. Any shape can be used as long as it can be regulated. Furthermore, the gap between the slits 52 may be narrowed so that the slits 52 are closed by the slight contraction of the nipple 1 that occurs when the infant sucks the nipple A. In this case as well, the infant , the chewing motion can induce the person to drink the beverage. Note that the wall thickness W of the check valve 5 is generally set to about 0.5 to 5M.
