The invention relates to a waste treatment apparatus (10) comprising a container (12) having a bottom (24), a peripheral wall (26) and a lid (16) for closing the container opening. The lid (16) includes a drum housing (58) and a drum body (78) rotatably connected to the lid (16). The waste treatment device (10) further comprises a flexible sealing member (64) connected to the drum housing (58), the sealing member extending radially inward from the connecting portion, in a substantially odorless manner. In order to seal the opening, it has a sealing portion capable of sealing contact with the outer surface of the drum body (78). According to the present invention, the end of the flexible sealing member (64) away from the connecting portion is formed on the drum housing (58) so that a freely movable free end of the flexible sealing member (64) is formed. ). [Selection] Figure 1【解決手段】本発明は、底(24)、周壁(26)、容器開口部を閉鎖する蓋(16)をもつ容器(12)を含む廃棄物処理装置(10)に関する。蓋(16)は、ドラムハウジング(58)と蓋(16)に回動可能に連結されたドラム本体(78)とを備える。廃棄物処理装置(10)はさらに、ドラムハウジング(58)に連結された可撓性密閉部材(64)を備え、密閉部材は連結部から径方向内側に延び、実質的に無臭の方法で容器開口部を密閉するためにドラム本体(78)の外面に密閉接触することのできる密閉部を有する。本発明によれば、可撓性密閉部材(64)の自由に移動可能な自由端が形成されるように、連結部から離れた可撓性密閉部材(64)の端部はドラムハウジング(58)に連結されていない。【選択図】図1
