Patent ID: 8863969

Claim:
A feeding bottle system comprising: a feeding bottle comprising an elongated body with a central longitudinal axis, and a neck configured for mounting a nipple thereto; and at least two positioning marks, comprising: a central mark ( 20 ) configured for orienting an angular position of the bottle around its central axis so that the central mark ( 20 ) faces upwards during feeding; and a first side mark ( 22 A) configured in such a way as to guide a user to incline the bottle relative to the horizontal until an optimum inclination is reached where a free surface of a liquid inside the bottle simultaneously passes through both the first side mark ( 22 A) and an outlet orifice of a nipple mounted on the neck, thereby causing a hydrostatic pressure of the liquid at the outlet orifice to be substantially zero; and further comprising a nipple crown for mounting a nipple to the neck of the feeding bottle; wherein the positioning marks are formed or printed on the nipple crown; and wherein the central mark ( 20 ) is disposed on the nipple crown (defining a vertical reference line passing through the central mark); and wherein the nipple crown further comprises three pairs of side positioning marks: a first pair of side marks ( 22 A, 22 B), a second pair of side marks ( 22 A′, 22 B′), and a third pair of side marks ( 22 A″, 22 B″), disposed on at least a side face of the nipple crown; and wherein the three side marks ( 22 A, 22 A′, 22 A″) are also mirrored symmetrically as three paired side marks ( 22 B, 22 B′, 22 B″) paired respectively across the vertical reference plane on an opposite side of the nipple crown; and further wherein: the first pair of side marks ( 22 A, 22 B) comprises a single line or bump/ridge; the second pair of side marks ( 22 A′, 22 B′) comprises two closely-spaced parallel lines or bumps/ridges; and the third pair of side marks ( 22 A″, 22 B″) comprises three closely-spaced parallel lines or bumps/ridges.
