Silicone baby bottle with enhanced water sealing

A silicone feeding bottle having enhanced water-sealing, comprising:

• a body that is configured so that a top portion thereof is opened to contain contents, consists of a corrugated pipe having a gently curved surface with a cross-sectional width gradually decreasing from a bottom surface to an upper portion, and is formed into a trumpet-shaped funnel, a conch shape, or a horn shape;
• a nipple portion attached to or detached from a distal coupling part of the body;
• and
• a fastening means for coupling the nipple portion and the body,
• wherein the fastening means consists of a first fastening ring and second fastening ring having a semicircular ring shape that opens and closes around a hinge,
• an upper fastening protrusion and a lower fastening protrusion are formed along inner peripheries of the first and second fastening rings,
• a first inclined surface facing downward is formed on the upper fastening protrusion, and a second inclined surface facing upward is formed on the lower fastening protrusion, and the first and second inclined surfaces engage in a ring shape and are coupled to a basal coupling part of the nipple portion and the distal coupling part,
• the basal coupling part consists of a base fastening protrusion that has a right-angled L-shape and engages the upper fastening protrusion, a base horizontal surface extending parallel to a distal coupling protrusion, and a base vertical surface extending from the base horizontal surface in a right angle direction, and
• the distal coupling part consists of a distal coupling protrusion formed to engage the lower fastening protrusion, a distal horizontal surface extending from the distal coupling protrusion to make surface contact with the base horizontal surface, and a distal vertical surface extending from the distal horizontal surface and corresponding to the base vertical surface.
