Wet Seal Cachets

They are made up of two similar convex halves having flat edges. The weighed amount of powder is placed in one half. The edges of the other are moistened with water and placed exactly over the first half containing the powder. Edges of both the halves are pressed together so as to make a perfect seal.

Dry Seal Cachets

They consist of two halves, the upper half and the lower half. The former one is little larger in diameter than the lower half. The powder is filled in lower half and upper half is fitted over it like a lid over a box. The backs of upper as well as lower halves have small projections which are used to fix the cachet in the holes of the machine. The lower halves are fitted into the lower plate of a machine and powder filled in them. The upper halves are fitted in the upper plate by means of projections, which will not allow the cachet to fall when the plate is removed. The upper plate is pressed on the lower plate forcing the upper halves or lids to fit exactly over the lower halves. The filled cachets are removed and packed in boxes.

Dispensing: The cachets are dispensed in a box if necessary empty spaces are filled by cotton wool so as to fix them properly in the boxes. The boxes are labeled with direction of use “Immerse in water for few seconds and then swallow with little water.”
