Abstract
Abstract A combined capillary mat and platform formed of a bottom piece of material having individual air cells which rest on a base to provide a platform and a sheet of mat material attached to the top of the first piece for providing capillary action. The combined mat and platform are preferably made by melting particles or granules of material on a surface of the mat which is thereafter bonded under pressure to the top surface of the bottom piece.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
187 words
A plant tender system comprising a tray having a bottom and side walls for holding a liquid; an integral mat platform unit for disposition in said tray, said mat platform formed by a first piece of flexible, liquid non-permeable material having a plurality of spaced projecting air cells on its bottom for resting directly on the tray bottom, and a second piece of flexible material having capillary action when wetted by liquid in the tray bonded to the top of said first piece above said air cells and generally coextensive with said first piece to form an integral mat platform unit, said air cells of said first piece of material resting directly on the bottom of said tray and forming a support for at least one free standing weighted object placed on the top of said second piece, liquid being stored in the tray including in the space between said air cells, said second piece receiving the liquid in the tray which is distributed throughout said second piece by capillary action to supply the liquid to a said object as it is supported above the tray bottom.
Claim 2
Dependent Claim
187 words
A plant tender system comprising a tray having a bottom and side walls for holding a liquid; an integral mat platform unit for disposition in said tray, said mat platform formed by a first piece of flexible, liquid non-permeable material having a plurality of spaced projecting air cells on its bottom for resting directly on the tray bottom, and a second piece of flexible material having capillary action when wetted by liquid in the tray bonded to the top of said first piece above said air cells and generally coextensive with said first piece to form an integral mat platform unit, said air cells of said first piece of material resting directly on the bottom of said tray and forming a support for at least one free standing weighted object placed on the top of said second piece, liquid being stored in the tray including in the space between said air cells, said second piece receiving the liquid in the tray which is distributed throughout said second piece by capillary action to supply the liquid to a said object as it is supported above the tray bottom.
Claim 3
Dependent Claim
17 words
A plant tender as in claim 1 wherein said second piece is made of a non-woven material.
Claim 4
Dependent Claim
18 words
A plant tender as in claim 2 wherein said non-woven material is a combination of rayon and polyester.
Claim 5
Dependent Claim
28 words
A plant tender as in claim 1 wherein said second piece has particulate or granular plastic material adhered thereto which bonds said second piece to said first piece.
Claim 6
Dependent Claim
18 words
A plant tender as in claim 4 wherein said non-woven material is a combination of rayon and polyester.
Claim 7
Dependent Claim
16 words
A plant tender as in claim 5 wherein said particles or granular material are of polyethylene.
Claim 8
Dependent Claim
142 words
An integral combined capillary mat and platform for a plant tender system comprising a bottom piece of flexible, liquid non-permeable material formed with a plurality of spaced, projecting air cells which are adapted to rest directly on a surface and provide reservoir areas containing liquid in the spaces between said air cells, and a top piece of flexible capillary material adhered to the surface of said bottom piece opposite the surface from which said air cells extend and generally coextensive therewith to form a substantially flat area, said air cells of said bottom piece beneath said flat area of said top piece when resting on said surface also forming a support for at least one free standing weighted object placed on the top surface of said top piece in the flat area which supplies liquid throughout said top piece by capillary action.
Claim 9
Dependent Claim
142 words
An integral combined capillary mat and platform for a plant tender system comprising a bottom piece of flexible, liquid non-permeable material formed with a plurality of spaced, projecting air cells which are adapted to rest directly on a surface and provide reservoir areas containing liquid in the spaces between said air cells, and a top piece of flexible capillary material adhered to the surface of said bottom piece opposite the surface from which said air cells extend and generally coextensive therewith to form a substantially flat area, said air cells of said bottom piece beneath said flat area of said top piece when resting on said surface also forming a support for at least one free standing weighted object placed on the top surface of said top piece in the flat area which supplies liquid throughout said top piece by capillary action.
Claim 10
Dependent Claim
35 words
A combined capillary mat and platform as in claim 7 wherein said top piece has a plurality of particles or granules adhered to its bottom surface for adhering said top piece to said bottom piece.
Claim 11
Dependent Claim
20 words
A combined capillary mat and platform as in claim 7 wherein said top piece is made of a non-woven material.
Claim 12
Dependent Claim
23 words
A combined capillary mat as in claim 7 wherein said non-woven material is a combination of rayon and polyester or other non-woven fiber.
Claim 13
Dependent Claim
35 words
A combined capillary mat as in claim 8 wherein said top piece has a plurality of particles or granules of polyethelene adhered to its bottom surface for bonding said top piece to said bottom piece.
