The invention relates to a detergent tablet comprising a body made from compacted powder, said body being coated with a water-soluble coating, said water-soluble coating having a composition comprising a film-forming agent and water, characterised in that the composition of the water-soluble coating further comprises at least one specific agent for improving the efficiency in terms of rinsing of the detergent tablet.

Coated detergent tablet

A press device for manufacturing compacted tablets from at least one mixture in powder form, including at least one compaction assembly including a lower punch and an upper punch each having an active compaction surface and placed on either side of a die. The lower punch has a longitudinal recess open on the side of the die, inside of which is mounted a central rod which is translatably mobile relative to the lower punch. The central rod is coupled to the lower punch by a resilient link provided so as to hold, in an inoperative position, the central rod in a maximum deployed position in which the central rod protrudes relative to the active surface of the lower punch. The invention also relates to a specific compaction method and to a multi-layer compacted tablet with a recess.
