Flow control valve for infant feeding device

A kit comprising:

• at least two dome-shaped removable fluid flow valves comprising varying flow rates;
• wherein each of the at least two dome-shaped removable fluid flow valves comprises:
• a plastic ring;
• a flexible layer overmolded onto the plastic ring, wherein the flexible layer comprises a plurality of bumps such that the flexible layer comprises a wavy profile;
• a central opening having a diameter of diameter in the range of 0.1 mm to 0.32 mm;
• a feeding device comprising:
• a fluid reservoir;
• a nipple configured to be attached to the fluid reservoir, wherein the nipple is configured to retain one of the at least two dome-shaped removable fluid flow valves within an interior space of the nipple, wherein an internal cavity is formed between the one of the at least two removable fluid flow valves and the nipple, wherein the plurality of bumps extend into the internal cavity, wherein the plurality of bumps abut against a wall of the nipple to support the wall of the nipple, and wherein, when each of the at least two dome-shaped removable fluid flow valves are positioned within the interior space of the nipple, the central opening is configured to control a flow rate of a fluid from the fluid reservoir into the internal cavity.

A nipple comprising:

• a dome-shaped removable fluid flow valve configured to be positioned within an interior space of the nipple;
• an internal cavity between the removable fluid flow valve and a wall of the nipple;
• wherein the removable fluid flow valve comprises:
• a plastic ring;
• a flexible layer overmolded onto the plastic ring, wherein the flexible layer comprises a plurality of bumps extending into the internal cavity such that the flexible layer comprises a wavy profile, wherein the plurality of bumps abut against the wall of the nipple to support the wall of the nipple;
• a central opening having a diameter of diameter in the range of 0.1 mm to 0.32 mm;
• and wherein, when the removable fluid flow valve is positioned within the interior space of the nipple, the central opening is configured to control a flow rate of a fluid through the nipple.
