Patent number: 5860249Abstract: A plant watering container assembly comprising a bottom container section having side and bottom walls defining a water reservoir, and a top container section removably connected to said bottom container section. The top container section includes an integrally formed funnel-shaped section having a side wall extending downwardly toward said reservoir and defining a conical opening for receiving a side wall of a potted plant, and further having an integrally formed annular bottom wall defining at its radially inner edge a central opening through which a watering wick can pass downwardly into the reservoir. In the event the container is tipped or turned, water in the container reservoir is trapped in an annular chamber defined by the wall of the funnel and the top and bottom container sections, thereby precluding water passing outwardly through the central opening of the funnel-shaped section.Type: GrantFiled: June 12, 1996Date of Patent: January 19, 1999Assignee: International Plant Breeding AGInventor: Reinhold Holtkamp, Jr.

Patent number: 5857289Abstract: An apparatus for determining a critical level of soil humidity for plants including an external body, a soil recipient container hermetically sealed to the external body so as to receive a soil sample therein, a well positioned within the external body and containing water therein, a pressure cell connected to the well so as to controllably pass water from the well to the soil recipient container, and an air admitting pipe in sealed relationship with the external body. The pressure cell has a preestablished resistance to the passage of water. The soil recipient container has a collecting pipe thereon for passing water into the soil. The air admitting pipe has an end which opens exterior of the external body so as to allow air to pass into the external body. The air admitting pipe communicates with the pressure cell. The air admitting pipe serves to transmit air into the pressure cell when energy in the soil recipient container is higher than the resistance of the pressure cell.Type: GrantFiled: August 13, 1996Date of Patent: January 12, 1999Inventor: Fernando Antonio Franco da Encarnacao

Patent number: 5852896Abstract: A container and methodolgy for growing a plant in soil, the soil within an area defined by an annular inner wall having an open top end to expose the soil and plant to ambient air; the inner wall includes transverse holes around its circumference and up its length. In one embodiment the inner wall includes a water impervious circumferal band at its upper end to help maintain the soil top surface dry. An outer annular wall of water impervious material laterally surrounds, in spaced relationship, the inner wall to define an open space with upper opening between the walls into which water can be applied and air may flow. The space between the walls at the bottom end thereof is sealed with a floor leaving only the transverse holes in the inner wall as flow paths through which the water enters the soil from the space. The volume of the space between the walls is sufficient to receive enough water to saturate the soil and provide some excess water for removing salts from the soil.Type: GrantFiled: November 10, 1997Date of Patent: December 29, 1998Inventor: Robert J. Flasch, Jr.

Patent number: 5815897Abstract: This invention is basically a planter combined with a cremation vault. The planter portion of the planter cremation vault is a cylindrical tube with a closed bottom. Within that tube is fitted a liner which is also a cylindrical tube with a closed bottom. Within the liner the dirt and the plants are placed. The cremation chamber is a tube adapted to attach to the planter. The cremated remains are placed within the cremation chamber. On top of the cremated remains a Styrofoam spacer is placed. On top the Styrofoam disk is placed a memorabilia container. The cremation chamber is sealed by attaching it to the planter. An extension cremation chamber may be added to place a second individuals remains. This extension cremation chamber would be adapted to thread within the cremation chamber and to allow the planter to thread within its top. The extension cremation chamber is a cylindrical container with a closed bottom. The planter is than attach to seal the extention cremation chamber.Type: GrantFiled: June 12, 1996Date of Patent: October 6, 1998Inventor: C. Philip Longstreth

Patent number: 5806240Abstract: A system for supplying dripping water to plant growing media comprises at least one water container and a support to hold the container upright over the soil to be watered. The support consists of a body having a soil engaging lower part and a water controlling upper part. A flexible tube is connected to a water passage provided in the upper part of the body. A screw is operated to compress the inner tube to control water passage in the tube and, consequently, the dripping rate of the water to the soil.Type: GrantFiled: July 23, 1997Date of Patent: September 15, 1998Inventor: Pierre Racine

Patent number: 5797217Abstract: Inserts and liners are provided to form self watering systems for potted plants which optimize delivery of the water to the plants and which minimize the time and labor required to maintain the plants. The system also allows the plant to be transplanted to a larger pot without damaging the integrity of the plant or the self watering system. The system consists of an insert and a liner. In each of the preferred embodiments, an insert is provided which can be placed in a pot of any size to provide a self watering system. In the preferred embodiment, the insert is formed from a walled containing device separated into first and second compartments by a barrier extending inwardly from the perimeter of the walled containing device. The first compartment has a greater diameter than the second compartment and has orifices adjacent the barrier along its perimeter. The roots grow through the orifices into the second compartment which contains water.Type: GrantFiled: March 1, 1996Date of Patent: August 25, 1998Inventor: Betty Magee
