Abstract
Improvements in the manufacture of siphon heads of injected material, which consist of making previously, based on a plastic material that can not alter the liquid that is to contain the siphon, a piece that includes the parts of the head to be put in contact with this liquid, then place this piece inside a mold corresponding to the total shape of the head of the siphon, conveniently fixing the position of this inner piece by means of punches or cores of the mold and injecting a hard plastic material and resistant, which forms the outside of the siphon head and is joined in the same injection operation with the material of the inner part to obtain a siphon head in which all the parts that can be brought into contact with the liquid, they are of a harmless material that does not alter this liquid in the least.
