Abstract:
1. A system for dispensing additives comprising: a container for retaining a base liquid having a threaded neck opening; a retaining element in peripheral contact with the threaded neck opening and having an additive dispensing hole; an additive bladder in contact with the retaining element, including a portion of an additive enclosed by the additive bladder; a cap for sealing the container enclosing the retaining element and the additive bladder having threads that rotatingly mate with the threaded neck opening; a sealing element for sealing a surface of the retaining element with respect to an interior surface of the cap; a concave element for pressing the additive bladder against the retaining element; and a spacer ring for securing the cap attached to an outer edge of the cap, wherein a height of the spacer ring corresponds to at least a displacement of the cap sufficient to press substantially all of the additive from the additive bladder; wherein the cap is configured to: upon rotation in a first angular direction, press the additive bladder against the retaining element in a closure direction, wherein the concave element presses against the additive bladder and the additive is released through the retaining element into the base liquid.
