Depending on the waste fraction, the following insert techniques can be applied:
A. a drum
B. a lid construction
C. an insert opening for cylindrical objects.

A. The insert drum
The insert drum can be manufactured out of Sendzimir galvanised steel with a polyester powder coating. There is also a stainless steel model available. A drum is available with a content size of approximately 60, 80 or 100 litres.

The drum has been designed so that fingers cannot become trapped and in a way which prevents the insertion of objects that are too large. Furthermore, the connection underneath the drum with the container is sealed off. With a Sendzimir drum this has been done by using a flap and with the stainless steel drum this is done using double shelled drums that turn into each other. When the outer shell is open for the insertion of waste, the inner shell ensures the hole is sealed off.

Jedná se o část nádoby na vhazování odpadu - lze říct jednoduše např. "buben pro vhazování"?

Celé to vypadá takhle, "drum" označuje tu horní část (pohyblivé víko):

Chápu to tak, že když se okraj bubnu/válce zvedne nahoru, opačný konec (ukrytý) se ve spodní části přesune dopředu a uzavře otvor vedoucí do spodní části systému (je tam podzemní kontejner na odpad).
