The present invention relates to a nursing bottle (100) for bottle feeding that is formed by the use of a silicone material. The present invention includes: a storage container (110) having an open portion (111) on its upper side with a space portion (112) disposed inside that is capable of accommodating a bottle feeding material； a pacifier (120) coupled with the open portion (111) of the storage container (110), having a suction unit (121) for bottle feeding at its center, and having in its vicinity an inlet side air valve (122) for causing outside air to flow into the storage container (110) by the medium of a pressure change occurring during bottle feeding and a coupling portion (125) with which an air vent pipe (130) for functioning as a flow path for air passing through the inlet side air valve (122) is coupled； the air vent pipe (130) coupled with the coupling portion (125)； and an outlet side air valve (140) coupled with a tip of the air vent pipe (130) such that the air flowing into the air vent pipe (130) can flow out into the storage container (110). According to the present invention, dissolving in the bottle feeding material of the outside air that flows into the container during bottle feeding due to an infants suction force or contact of the bottle feeding material with the outside air that flows into the container during bottle feeding due to the infants suction force is minimized, and thus the occurrence of diseases such as stomach ache attributable to air suctioning can be tackled, deterioration attributable to contact with air can be addressed, and the length of time during which the bottle feeding material can be stored can be maximized.본 발명은 실리콘 재질로 이루어진 수유를 위한 젖병(100)에 관한 것으로서, 상측에 개방부(111)를 가지면서 내부에는 수유물질을 수용할 수 있는 공간부(112)를 갖는 저장용기(110)와； 상기 저장용기(110)의 개방부(111)에 체결되되 중앙에 수유를 위한 흡입부(121)를 가지면서 주변에는 수유 시 수반되는 압력변화를 매개로 외부공기를 저장용기(110)내로 유입시키기 위한 입구측 에어 밸브(122)와 입구측 에어 밸브(122)를 통과한 공기 유로 역할을 위한 에어 통기관(130)이 체결되는 체결부(125)를 갖는 젖꼭지(120)와； 상기 체결부(12
