Plant tube for use in flower pots
First Claim
1. A plant tube for insertion into a plant pot in a substantially upright position, the plant tube comprising an at least partly open non-narrowing lower end portion, means provided at said lower end portion for defining at least one root penetration opening for enabling roots of a plant in the plant tube to freely penetrate radially outwardly and downwardly of the plant tube, and wherein said means for defining includes at least protrusion of a planar thin-walled shape projecting downwardly from the lower end of the plant tube and terminating in a rigid outer end for abutting a bottom of the plant pot.

Abstract
A plant tube (6) for insertion into a plant pot (2) in a substantially upright position. The plant tube (6) includes an at least partly open, non-narrowing lower end (12), with at least one planar thin walled protrusion (20) provided at the lower end (12) for defining at least one root penetration opening enabling the roots of the plant in the plant tube (6) to freely penetrate radially outwardly and downwardly from the plant tube (6).

1. A plant tube for insertion into a plant pot in a substantially upright position, the plant tube comprising an at least partly open non-narrowing lower end portion, means provided at said lower end portion for defining at least one root penetration opening for enabling roots of a plant in the plant tube to freely penetrate radially outwardly and downwardly of the plant tube, and wherein said means for defining includes at least protrusion of a planar thin-walled shape projecting downwardly from the lower end of the plant tube and terminating in a rigid outer end for abutting a bottom of the plant pot.
-
2. A plant tube according to claim 1, wherein the means for defining includes a plurality of protrusions arranged as radial plate portions joined along an axially extending line of the plant tube.
-
3. A plant tube according to claim 2, wherein the radial plate portions include outer edges extending downwardly from the lower end portion and converging inwardly toward a central line of the plant tube.
-
4. A plant tube according to one of claims 2 or 3, wherein the radial plate portions are arranged cross-sectionally as mutually orthogonal diametrical plate members.
-
5. A plant tube according to claim 1, wherein an upper end portion of the plant tube has an increased diameter relative to a diameter of the lower end portion thereof.
-
6. A plant tube according to claim 2, wherein said axial line is disposed substantially along a central axial line of the plant tube.
-
7. A plant tube for insertion into a plant pot in a substantially upright position and for accommodating at least one plant therein, the plant tube comprising an open upper end, an at least partly open lower end portion axially spaced from said open upper end for enabling a root penetration of the at least one plant accommodated in the plant tube, a generally non-narrowing portion contiguous with the at least partly open lower end portion of the plant tube, and plate means projecting downwardly from the at least partly open lower end portion for stabilizing the plant tube in the plant pot, said plate means including an inner edge disposed along an axially extending line passing through an interior of the plant tube and an outer edge extending from an outer periphery of the lower end portion in a converging direction toward said inner edge such that a point of intersection of the inner and outer edges forms a terminating end of the plant tube adapted to contact a bottom portion of the plant pot whereby the lower end portion of the plant tube is spaced from the bottom portion of the plant pot thereby permitting roots of the at least one plant to penetrate freely radially outwardly and downwardly from the lower end portion of the plant tube.
-
8. A plant tube according to claim 7, wherein said plate means includes a plurality of plates joined together along said axially extending line.
-
9. A plant tube according to claim 8, wherein each of said radial plates has a wall thickness substantially equal a wall thickness of the plant tube.
-
10. A plant tube according to claim 9, wherein said terminating end is a pointed end to facilitate insertion into the plant pot.
-
11. A plant tube according to claim 10, wherein said plates are arranged as mutually orthogonal diametrical plate members.
-
12. A plant tube according to claim 11, wherein said axially extending line is disposed substantially along a longitudinally extending center line of the plant tube.
