a) a first portion connected to an opening of the receptacle;
b) a second portion located above the first portion;
c) a chamber for containing the substance, the chamber being at least partially located within the first portion;
d) a seal located below the chamber, the seal retaining the substance in the chamber;
e) a chamber cutter, the chamber cutter being at least partially located within the first portion and second portion;
f) a third portion located above the second portion,
g) a removable stop member, the second portion being adapted to support the removable stop member prior to the release of the substance, and the third portion after the release of the substance; and
wherein removal of the stop member enables the third portion to be moved downwardly which causes the chamber to be moved downwardly to cause the seal to open and release the substance into the receptacle, wherein the seal further includes a tab extending upwardly and resting between a wall of the receptacle and the first portion and wherein the assembly further includes:
h) a recess in a downwardly extending part of the third portion, and
i) a lateral projection on a vertical lip on the top of the second portion, wherein the recess is shaped complementary to the shape of the lateral projection, wherein the lateral projection on the vertical lip fits into the complementary shaped recess in the downwardly extending part when the third portion is pushed and lowered onto the second portion which locks the third portion to prevent movement between the second portion and the third portion once the substance has been released into the receptacle.
