A vent prevents a vacuum from forming within an inverted container of liquid when the liquid is dispensed. The vent is a singular vent, formed of a vent tube, the vent tube removably secures with a nipple, and more particularly its radially extending flange, with the nipple flange having a passage therethrough to allow for venting by way of the vent tube from the interior of the container to the location between the container neck and its collar, to provide for the entrance of atmospheric air into the interior of the container during usage to prevent the generation of any vacuum therein. The container may be a nursing bottle, with its collar and nipple applied to the top, and the vent tube being secured to the bottom of the nipple flange for projecting downwardly within the bottle to perform its venting function. The bottle may be formed of fully or partially transparent material, tinted to one or more coloration, while the vent tube may be tinted to one or more different coloration, and when they are assembled, exhibits three or more colorations for the vent tube when viewed from exteriorly of the tinted nursing bottle during its application.

A feeding teat (40) constructed and arranged to be used on a bottle (52) that holds and dispenses a liquid to be fed to an infant or child. The teat (40) has a nipple portion (70) with an orifice (71) at a terminal end, and defines an interior profile shaped by intersecting reverse curves (75, 76) that generally decrease the interior diameter of the nipple portion (70) toward the orifice (71), so as to channel fluid flow into the orifice (112). There is a flange portion (66) constructed and arranged to be releasably coupled to the bottle (52) such that the liquid can flow from the bottle (52) into the teat (40), and a convexly shaped intermediate portion (80) integrally connecting the nipple portion (70) to the flange portion (66). A pressure relief valve (60) built into the teat (40) is constructed and arranged to admit air into the interior of at least one of the teat (40) and the bottle (52).

A method of forming a nipple for a baby bottle, comprises: forming a lower conical wall section; forming a higher conical wall section molded above the lower conical wall section; preventing deformation of the higher conical wall section; and cutting an opening through the higher conical wall section into an interior section of the nipple.

A nipple for use with an infant drinking cup is disclosed herein. The nipple comprises a domed portion having a central region and an inner surface, a teat portion radially offset from the central region, and a radially-outer wall. The radially-outer wall is joined to the domed portion at a joining location and comprises an inner fluid-flow surface, defining a fluid flow direction. A region of the inner surface of the domed portion at the joining location is substantially parallel to said fluid flow direction, or the inner fluid-flow surface of the teat portion extends radially outwardly, away from said region of the inner surface of the domed portion at the joining location.

A baby feeding container contains a bottle, a whisking ball, a sealing ring, and a liquid outlet. The whisking ball is positioned within the bottle. The liquid outlet is pressed against an opening of the bottle with the sealing ring. The liquid outlet includes a nipple collar and a feeding nipple that ensure the liquid within the bottle flows out of the feeding nipple. If the user intends on measuring the amount of liquid within the bottle, a plurality of quantity markers can be used. Moreover, the whisking ball is insulated in a rubberized coating to minimize any noise generated when the baby formula is mixed in water by shaking the bottle.

A baby bottle blender includes a baby bottle having a top collar and a bottom collar, and a nipple. The nipple cap is removably attached to the top collar of the baby bottle and holds the nipple extending through a central aperture of the nipple cap onto the top collar. An agitating unit is centrally retained within a bottom attaching cap. A base member has a top recess to engage the agitating unit. An electrical mechanism in the base member operates the agitating unit, so that the agitating unit will thoroughly blend a formula in a liquid in the baby bottle in approximately seven seconds.
