Abstract:
A plant containerizing and watering device for containing a plant growing medium and facilitating irrigation of said growing medium by a liquid, said device comprising in combination:a first container, said first container defining a first base wall and a first peripheral wall extending from said first base wall;a second container, said second container defining a second base wall and a second peripheral wall extending from said second base wall, said second base wall having at least one base wall venting aperture extending therethrough, said second peripheral wall being provided with at least one peripheral wall venting aperture extending therethrough;said second container being configured and sized so as to be at least partially insertable within said first container with said first base wall and said second base wall maintained in a predetermined base wall spaced relationship relative to each other by a base wall spacing means extending therefrom, said first and second base walls defining a base reservoir volume therebetween; said second peripheral wall being configured and sized so as to be in a spaced relationship relative to said first peripheral wall when said second container is at least partially inserted within said first container all around the periphery of said second peripheral wall so as to allow air flow between said first peripheral wall and said second peripheral wall;a trough extending outwardly from said second base wall, said trough being provided with at least one trough aperture extending therethrough, said though being configured and sized so that said at least one trough aperture is positioned within said base reservoir at a trough aperture distance from said second base wall when said first and second base walls are in said base wall spaced relationship relative to each other;a removable reservoir for containing a variable volume of said liquid, said removable reservoir being configured and sized so as to be at least partially and removably insertable within said second container;a valve means for selectively blocking the transfer of said liquid from said removable reservoir to said base reservoir volume, said valve means being in fluid communication with said removable reservoir, said valve means being configured such that when said removable reservoir is in an operational position within said second container said valve means selectively and automatically allows a transfer volume of said liquid to flow from said removable reservoir to a relatively constant volume of said liquid contained within said base reservoir volume so that the surface of said relatively constant volume of said liquid is maintained at a relatively constant base reservoir liquid level, said base reservoir liquid volume allowing fluid communication with said at least one trough aperture while being spaced from said second base wall so as to allow simultaneous venting through said at least one base wall venting aperture and said at least one peripheral wall venting aperture,whereby when a fraction of said relatively constant volume of said liquid is soaked up through said at least one trough aperture by a capillary action of said growing medium contained in said second container said valve means transfers a corresponding volume of said liquid from said removable reservoir to said base reservoir volume.
