Abstract

The invention relates to a soap dispenser assembly comprising a soap dispenser and at least two pieces of soap. The at least two pieces of soap each comprises a top surface and a bottom surface and can be stacked thereby rotationally coupling the pieces of soap in at least one direction via locking profiles. The soap dispenser comprises a soap holder arranged to contain, and rotationally couple, the pieces of soap in a stacked position, a knife-blade module and a biasing module. The top surface of an upper most piece of soap interfaces with the biasing module. The bottom surface of a lower most piece of soap interfaces with the knife-blade module. The biasing module is arranged to bias the at least two pieces of soap towards the knife-blade module. The knife-blade module comprises at least one blade arranged to scrape the bottom surface of the second piece of soap upon rotation of the soap holder with the at least two pieces of soap relative to the knife-blade module.
