PURPOSE: An elastic nursing bottle is provided to reduce the volume of an inner container by forming a multi-stage corrugation part. CONSTITUTION: An elastic nursing bottle comprises a transparent outer container(10) which is made of a plastic material, and an inner container(20) which is made of a silicone material and has elasticity. The inner container is formed with a multi-stage corrugation part(21). The volume of the inner container is reduced by the folding of the corrugation unit due to negative pressure. An insertion groove is formed in the upper end of the outer container. |
