  • Patent number: 5259142
    Abstract: A plant irrigation device for a potted plant includes a hollow stake adapted to be inserted into the soil adjacent to the plant, and a bottle supported on the stake in an inverted position. The bottle is provided with a dispensing cap which has a spout extending down into the hollow stake, and which causes liquid contained in the bottle to drip down through the stake into the soil. A replaceable disc-shaped filter is mounted in the cap which filters sediment out of the liquid through the spout, and which serves to prevent clogging of the spout. The filter also acts as a restrictor which causes the liquid to drop slowly from the bottle as a function of the quantity of filter material in the cartridge.

  • Patent number: 4532722
    Abstract: A device for dispensing a fabric conditioner which in one embodiment takes the form of a small dispensing container which is filled with an absorbent material saturated with a liquid fabric conditioner. The dispensing container is provided with a number of holes, and when the container is placed in an automatic laundry dryer, the heat of the dryer causes the liquid conditioner within the container to be vaporized so that conditioning vapor passes through the holes of the container and conditions the clothes in the dryer so as to free them from static cling. In a second embodiment the absorbent material saturated with conditioner is placed in a bag formed of porous fabric material, which when placed in a dryer causes conditioning vapor to pass through the pores in the fabric to condition the clothes in the dryer. In a third embodiment a dispensing container is provided with an opening covered by the porous fabric material through which the conditioning vapor passes.
