    Abstract: The invention described herein is that of an outdoor drain filter useful for maintaining the operability of an outdoor drain despite the accumulation of debris that would otherwise obstruct the outdoor drain, resulting in flood prevention of surrounding areas. The outdoor drain filter of the present invention is placed above and around an existing outdoor drain or may be integral with a drain cover or drain reservoir. The outdoor drain filter comprises upper and side filtration means allowing the free flow of water therethrough. The outdoor drain filter further comprises a diverter comprising at least one air vent and at least one lateral pipe that defines a maximum water level to which water will accumulate around the outdoor drain before being diverted into the drain through the diverter. The outdoor drain filter may a manufactured unit or of modular construction.

    Abstract: The present invention is a planting device design for multiple plant containers. Said planting device incorporates a reservoir and a wick for each plant container. When placing the plant container through the lid, a flap is opened. Said flap positions the plant container so that the wick is in contact with the water, but the container containing the soil is not in contact with the water. This reduces the possibility of rot. Said flap also closes when the plant container is removed thereby preventing pollutants (e.g. insects, leaves) along with pets or light from communicating with the water.

    Abstract translation: 本发明是用于多个植物容器的种植装置设计。 所述种植装置包括用于每个植物容器的储存器和芯。 当将植物容器放置通过盖子时，打开瓣片。 所述翼片将植物容器定位，使得芯与水接触，但容纳土壤的容器不与水接触。 这样可以减少腐烂的可能性。 当植物容器被去除时，所述皮瓣也关闭，从而防止污染物（例如昆虫，叶子）以及宠物或光与水连通。
