To improve safety during feeding with a feeding bottle by absorbing impact on the mouth of a little child or its periphery by the feeding bottle even when the little child falls down keeping the feeding bottle in his/her mouth.

The safety device A for the feeding bottle is a blind cylindrical body 1 composed of an elastic material and is provided with a feeding bottle insertion part 2 for fitting the feeding bottle B and a feeding bottle bottom part peripheral edge holding part 4 provided on the inner surface of the roughly middle part of the blind cylindrical body. When impact force is imparted, the holding part 4 is bent in the bottom surface direction of the safety device A, the safety device for the feeding bottle near the formation part of the holding part 4 is swollen to the outside, and passing by the slide of the bottom part of the feeding bottle is allowed. The safety device for the feeding bottle is provided with a function of absorbing the impact imparted to the feeding bottle and breaking the downward movement of the feeding bottle by frictional force when the holding part 4 is bent, restoration force after it is bent and restoration force generated by the swelling of the safety device for the feeding bottle when the impact force is imparted.
