Plant Pot Having Drain Opening

Abstract

A plant pot 1 comprises a bounding wall 2 formed by a side wall 3 and a bottom 5 and includes a gel space 7 in which swellable gel grains 9 are accommodated filling the gel space in swollen state.

The plant pot further includes a substrate space 11 in which a substrate, for example, soil is accommodated. A bounding wall portion 2A, 2B bounds a part of the second space 11. Drainage openings 13 are located in the bottom 5 of this bounding wall portion 2B next to the gel space 7.

The first space 7 is partly bounded by a further bounding wall portion 2D, 2E of the bounding wall 2. Aeration openings 14 are located in this further bounding wall portion.

The gel grains 9 are contained in a pad which further includes a flexible separation sheet 15 which forms a root-permeable separation between the gel and soil during use.

DETAILED DESCRIPTION OF THE DRAWINGS

[0033] FIG. 1 represents a sectional view taken through a first embodiment of the plant pot according to the invention. The left half of the Figure represents the plant pot 1 prior to being used and containing gel in the form of grains in a non-swollen state and the right half of the Figure represents the plant pot during use containing gel grains swollen into a gel layer 10 and containing a substrate layer 12 on top of the gel layer. The substrate layer in this example is a layer of soil.

[0034] The plant pot 1 comprises a bounding wall 2 formed by a side wall 3 and a bottom 5 and has a first space which forms a gel space 7 and is located above the bottom and between the side wall. This gel space 7 contains swellable gel grains 9 in swollen state filling the gel space. The plant pot further has a second space which forms a substrate space 11 which is located above and/or beside the gel space and which contains a substrate, for example, soil during use. A bounding wall portion formed by the top 2A of the side wall 3 and an outer ring 2B of the bottom 5 bound a part of the second space 11.

[0035] The bottom 5 of this bounding wall portion has in addition to the gel space 7 drainage openings 13 via which the substrate space 11 is connected to the space outside the plant pot. The drainage openings 13 are present at the height of a lower bounding wall 2C of the bounding wall portion 2A, 2B. The former space 7 is partly bounded by a further bounding wall portion 2D, 2E of the bounding wall 2. Aeration openings 14 are provided in this further bounding wall portion. The gel grains 9 are present in a pad which further includes a flexible separation sheet 15 which forms a root-permeable separation between the gel and the soil during use.

[0036] The plant pot further has a plate 17 which is detachably attached to the under side of the bottom 5 and is located solely underneath the gel space 7. Furthermore, the plant pot has a plurality of removable plugs 19 which can shut off the drainage openings 13.

[0037] FIG. 2 represents a sectional view taken through a second embodiment of the plant pot. In this plant pot 21 the bottom is provided with a partition wall 22 which is located within the side wall 3 and is lower than the side wall, while the gel space 7 is located at one side of the partition wall.

[0038] FIG. 3 represents a plan view of the plant pot represented in FIG. 1. The drainage openings 13 are located in a raised part of the bottom 5 which is located in annular form against the side wall 3.

[0039] FIG. 4 represents a plan view of a third embodiment of the plant pot. In this plant pot 31 the drainage openings 13 are located in local raised parts of the bottom 5.

[0040] FIG. 5 represents a sectional view taken through a fourth embodiment of the plant pot. In this plant pot 41 the partition wall 23 is double-walled, while the space 27 between the wall portions 23A and 23B at the under side of the plant pot has an open connection to the environment through a channel 43 that is formed by a recess 45 in the side wall and a vaulted part 47 of the bottom. The gel space 7 is then located within the partition wall 23 whose inner wall portion 23A is provided with slotted aeration openings 49. The lower part of the inner wall portion 23A and the part of the bottom 5 within the partition wall 23 are then closed and may form a water buffer.

[0041] FIG. 6 represents a sectional view taken through a fifth embodiment of the plant pot. In this plant pot 51 the gel space 7 is located between the partition wall 25 and the side wall 3.

[0042] FIG. 7 represents a sectional view taken through a sixth embodiment of the plant pot. In this plant pot 71 is located a flexible sheet 73 spread across the aeration openings 75 in the bottom 5 and the drainage openings 13 are located in the outside wall 3 above the gel layer 10 at the height of the substrate layer 12.

[0043] FIG. 8 represents a sectional view taken through a seventh embodiment of the plant pot. This plant pot 61 has a plate 62 that has a closed plate bottom 63 and an upright plate wall 65. This plate is located underneath the bottom 5 and surrounds the lower part of the side wall 3. Between the plate wall and the lower part of the side wall is situated a third space 67. This third space enhances a strong air circulation thus enhancing the growth of the plant. As a result of this, the roots present in the first space are situated in a moist, but aeratable space.

[0044] FIG. 9 represents a sectional view taken through an eighth embodiment of the plant pot. In this plant pot 91 the gel layer 10 is located above a first part of the bottom 5 and the outer ring of the bottom forms a second part above which there is no gel layer.

[0045] FIG. 10 represents a sectional view taken through a ninth embodiment of the plant pot. In this plant pot 91 the partition wall forms part of an inner pot 93 which is located on the bottom 5. The bottom of the inner pot and the bottom of the plant pot beneath it are provided with aeration openings (not shown in this drawing).

[0046] Albeit the invention has been described in the foregoing with reference to the drawings, it should be pointed out that the invention is not by any manner or means restricted to the embodiments shown in the drawings. The invention also extends over any embodiments deviating from the embodiments shown in the drawings within the scope defined by the claims.
