    • A dispensing device comprises a body (4) defining compartments (6) and (8) separated by a flexible impermeable membrane (10). Compartment (8) is closed off by a semi-permeable membrane (26) adjacent which a water container (30) is disposed. An apertured delivery tube (22) leads from compartment (6). The device may be used to dispense a cleaning, disinfectant and/or fragrancing gel into a toilet bowl. On flushing, water enters the container (30) and migrates through the membrane (26) increasing the pressure in an osmotic agent or swellable hydrogel in compartment (8). This imposes a pressure on flexible membrane (10) to displace gel from compartment (6) into the toilet bowl through apertures (24) in tube (22).
    • 分配装置包括限定由柔性不可渗透膜(10)分隔的隔室(6)和(8)的主体(4)。 隔室(8)由与其相邻的半透膜(26)封闭,水容器(30)布置在该隔室附近。 有孔输送管(22)从隔室(6)引出。 该装置可用于将清洁,消毒和/或加香凝胶分配到马桶中。 在冲洗时,水进入容器(30)并且通过膜(26)迁移,增加隔室(8)中的渗透剂或可膨胀水凝胶中的压力。 这在柔性膜10上施加压力以通过管22中的孔24将凝胶从隔室6移入马桶。
