Abstract: An anti-colic baby feeding bottle (10) includes a bottle body (16) having a bottle neck (18), a cap (14) removably fastened to the bottle neck (18), and an elastic teat (12). The teat (12) includes a nipple portion (24) having a fluid-dispensing through-hole (26) and an annular base (28), an annular flange (30) extending radially outward from the annular base (28), a plurality of apertures (32) formed 360° around the annular flange (30), and an annular skirt (40) depending from the annular base (28). The annular skirt (40) is spaced radially inward apart from an inner surface (42) of the bottle neck (18) to define an annular passage (44) having an outer end (46) in air communication with the apertures (32) and an inner end (48) which is normally closed by biasing force of a free end (50) of the annular skirt (40) that presses against the inner surface (42) of the bottle neck (18).

Abstract: A closure assembly for a water bottle, having a cap including a mouthpiece that has a first aperture through which water in the bottle can flow out upon the application of suction at the mouthpiece. A support inside the mouthpiece has at least one second aperture that, together with the first aperture, defines a path for water. Also included is a valve member that has a diaphragm located between the mouthpiece and the support. The diaphragm has an aperture in the path and bears resiliently against the support when no suction is applied to the mouthpiece, so its aperture is closed, blocking the path. Upon the application of suction at the mouthpiece, the diaphragm is deformed and moves away from the support so the aperture in the diaphragm is opened to permit the flow of water.
