Abstract
A plant growing device includes an envelope made of a vacuum formed film and having substantially planar first and second walls interconnected by a surrounding wall. A plant growing medium is enclosed by the envelope. The first and second walls each has a plurality of micro-holes, and a network of interconnected ribs that are indented from an outer surface of the first or second wall to define a plurality of flow guide channels. The second wall further has openings to receive plants. The first wall further has drain holes. The envelope has high air permeability due to the micro-holes while still possessing a relative high strength due to the network of ribs.
Claims9
A plant growing device comprising:
- an envelope made of a vacuum-formed film and having substantially planar first and second walls, and a surrounding wall connected between said first and second walls;
- and
- a plant growing medium enclosed by said envelope, and including a water-absorptive material selected from the group consisting of a polymeric foam, saw dust, charcoal, soil, sand, wood pulp, polymeric fibrous substances, and natural fiber materials;
- each of said first and second walls having a plurality of micro-holes extending therethrough, and a network of interconnected ribs, said ribs being indented from an outer surface of a respective one of said first and second walls and protruded inwardly from an inner surface of the respective one of said first and second walls to define a plurality of flow guide channels;
- said second wall further having a plurality of openings that are in spatial communication with said flow guide channels and that are adapted to permit extension of plants, said openings being larger than said micro-holes;
- said first wall further having a plurality of drain holes each of which tapers inwardly from said inner surface of said first wall, said drain holes being in spatial communication with said flow guide channels and larger than said micro-holes.
A plant growing device comprising:
- an envelope made of a sheet material and having substantially planar first and second walls, and a surrounding wall connected between said first and second walls;
- and
- a plant growing medium enclosed by said envelope, and including a water-absorptive material selected from the group consisting of a polymeric foam, sawdust, charcoal, soil, sand, wood pulp, polymeric fibrous substances, and natural fiber materials;
- said second wall having a plurality of openings that are adapted to permit extension of plants;
- said first wall having a plurality of drain holes;
- at least one of said first and second walls being made of a vacuum formed film having a plurality of micro-holes extending therethrough, and a network of interconnected ribs, said ribs being indented from an outer surface of said one of said first and second walls to define flow guide channels and protruded inwardly from an inner surface of said one of said first and second walls, said interconnected ribs defining a plurality of rings each of which surrounds a group of said micro-holes;
- said openings being larger than said micro-holes, said drain holes being larger than said micro-holes.
