Abstract: An apparatus configured for accommodating and dispensing a compound into a container is provided. The apparatus includes a body including an upper end portion, a lower end portion, and an opening defining a volume configured for accommodating the compound. The apparatus includes a lid removably coupled and moveable relative to the upper end portion of the body. The lid includes an upper end portion including an exterior surface and an interior surface. Further, the lid includes a protrusion extending downwardly from the interior surface of the lid by a second length greater than a first length of the body. The protrusion includes a gasket interposing between an inner surface of the body and an outer surface of the protrusion.

Abstract: A cap for accommodating a compound includes a body with an opening. The opening penetrates from an upper to a lower end portion of the body by a first length. A membrane seals a lower end portion of the opening. A lid is removably coupled and moveable relative to the body. The lid includes a protrusion extending downwardly from an interior surface of the lid by a second length greater than the first length. The opening accommodates a lower end portion of the protrusion. A spacer removably couples with the lid and interposes between the lid and the body. The spacer configurable between a first state in which the spacer is engaged with the lid, which prevents the protrusion from penetrating the membrane, and a second state in which the spacer is disengaged with the lid, which allows the protrusion of the lid to penetrate the membrane of the body.
