• the clustering unit comprises one or more openings for finger grip or similar.
• one of the contact parts comprises displacing means allowing for the clustering unit to be moved from a first operational position where the clustering unit is fixed to one or more other cans to a second position defined by the user.
• a part of each contact part is adapted for being permanently fixed to a can.
• One contact part is adapted for being permanently fixed to a can and does therefore not comprise disengagement means.
• the fastening means of the contact part preferably comprises an extending part, e.g. a lip, with a hole; and wherein the hole is made to fit over a pin or tap extending from the surface of the can, e.g. extending from the top face.

• the disengagement means 5 are constituted of a perforated line, e.g. perforated around 50% along the length of said perforation line, which makes it possible to lift the opposite end of the can up around 90 degrees, break the contact part 4 along the perforated line and thereby disengage the can from the cluster.
• one contact part 4D is adapted for being permanently fixed to a can and does therefore not comprise disengagement means.
• the fastening means 3D of the contact part 4D comprises an extending part, e.g. a lip, with a hole. The hole is made to fit over a pin or tap 8 extending from the surface of the lid of the can.
