Silicone baby bottle
View Patent ↗A silicone baby bottle which is made of silicone which does not generate environmental hormones is disclosed. The silicone baby bottle allows an infant or young child to be safely fed. The silicon baby bottle includes a body part, a nipple, and a coupling member composed of a first coupling ring and a second coupling ring which are screwed with each other to be coupled. The body part and nipple are made of silicone which is a soft material and the coupling member is made of a rigid material so that a coupled structure of the body part and nipple can be tightly sealed. Since only the body part and nipple made of silicone are allowed to come into contact with infant formula and infant's mouth, the infant is not exposed to environmental hormones attributable to synthetic resin.
1. A silicone baby bottle comprising:
a body part made of elastomer, the body part including a neck portion with an upper locking portion, and a shoulder portion extending from a lower end of the neck portion;
a nipple made of elastomer, the nipple including a flange coming into contact with an upper surface of the body part, a waist portion extending upward from an upper portion of the flange, and a tap extending upward from an upper portion of the waist portion; and
a coupling unit which couples the body part and the nipple to each other and which includes a first coupling ring coupled to the neck portion of the body part and a second coupling ring screwed with the first coupling ring and structured to cover an upper surface of the flange of the nipple,
wherein the first coupling ring is provided between the shoulder portion and the neck portion of the body part,
wherein the neck portion of the body part is provided with an air inlet, through which external air is introduced into the body part during feeding, in a mounting recess which is covered by the first coupling ring,
wherein the air inlet is formed in a tip of an air inlet protrusion, and
wherein an inside surface and an outside surface of the air inlet protrusion are surrounded by a barrier recess and an air inlet recess, respectively.
2. The silicone baby bottle according to claim 1 , wherein the air inlet functions as a valve that closes and opens for itself because the air inlet is made of a material having elasticity.
3. The silicone baby bottle according to claim 1 , wherein the nipple has a recess between the flange and the waist portion in the nipple, and
the second coupling ring is provided with a pushing portion which is inserted into the recess.
4. The silicone baby bottle according to claim 3 , wherein the pushing portion of the second coupling ring protrudes inward from an inside surface of the coupling ring, and
the pushing portion is disposed between a lower portion of the waist portion of the nipple and the recess.
5. The silicone baby bottle according to claim 1 , wherein the waist portion is thicker than a remaining portion of the nipple in order to impart rigidity and reinforce supportability of the nipple.
6. The silicone baby bottle according to claim 1 , wherein the upper locking portion of the neck portion of the body part includes a side extension extending in a radial direction from an upper portion of the body part, and a lower extension protruding downward from a lower end of the side extension and surrounding an upper end of the first coupling ring, and
the upper end of the first coupling ring is locked by the upper locking portion of the body part.
7. The silicone baby bottle according to claim 6 , wherein the first coupling ring has an insertion portion at the upper end, and
an inside surface of the side extension of the upper locking portion of the body part is provided with a recessed portion into which the insertion portion is inserted.
8. The silicone baby bottle according to claim 1 , wherein the shoulder portion of the body part is thicker than a remaining portion of the body part in order to impart rigidity and reinforce supportability of the body part.
9. The silicone baby bottle according to claim 1 , wherein an inside surface of the second coupling ring is provided with a pressing portion which directly presses the upper locking portion of the neck portion of the body part when the second coupling ring is coupled.
10. The silicone baby bottle according to claim 1 , wherein the first ring is provided with a coupling direction indicating mark.
