    The invention relates to a plastic plant pot (10) with a pot bottom (14), in which at least two radial and downwardly open channels (16) are embedded. Sectors (21, 22, 23) are formed between the channels, which also have a sector bottom (25, 26, 27) lying in a lower plane. The sector bottom (25, 26, 27) has openings in the sector bottom (25, 26, 27) through which the interior of the pot is watered, dewatered and aerated. Each sector bottom has a screen-like design over its entire surface with a plurality of uniform openings. This ensures that the interior of the pot with air and water is applied and discharged over a large area, while at the same time the plant soil is retained in the plant pot by the narrow meshes of the sieve-like sector bottom and cannot be flushed out through the openings.

    Plastic plant pot
    The invention relates to a plastic plant pot for receiving flowers and other plants.
    As a result of their good aeration and irrigation properties, plant pots with a so-called channel bottom have since found wide distribution. Such a plant pot is known from DE 40.00.950 A1. The pot bottom is provided with three channels which are open radially with respect to the underside of the pot and which form sectors between them with a sector bottom lying in the lower plane. An opening is provided in the sector bottoms, in particular for dewatering the plant pot. The opening is relatively large in order to ensure as much unhindered exchange of water and air as possible. The possible size of the openings in the sector bottom is, however, limited in that, from a certain opening size, plant soil can fall out of the plant pot or can flush out.
    The object of the invention is therefore to provide a plant pot with improved dewatering and improved retention of the soil, as well as with a suitable injection mold for its manufacture.
    This object is achieved according to the invention with the features of claims 1 and 8, respectively.
    The sector bottoms of the plastic plant pot according to the invention are screen-shaped over their entire surface, with a plurality of similarly shaped relatively small openings. By "sieve-like" is meant a structure that is formed by at least four openings, but the arrangement of the openings can follow a certain pattern, but is not necessarily necessary. The screen-like structure is further characterized in that a grid-shaped structure is formed between the openings, which holds the earth in the plant pot. Only through the sieve-like structure of the sector bottoms can a relatively large total surface area of all openings be realized, while at the same time the size of each individual opening can be chosen relatively small. In this way, on the one hand, it is ensured that the total area, including the corner areas, of the sector bottoms is well taken care of, that is, well watered and dewatered and aerated, and on the other hand it is ensured that plant soil is not flushed out of the pot by the sector bottom. can become.
    According to a preferred embodiment, the surface share of all openings of a sector bottom on the total surface of the sector bottoms is at least 20%, and in a particularly preferred embodiment at least 25%.
    The surface portion of the openings of the plant pot according to the invention is a multiple of the surface portion of conventional plant pots.
    The area of an opening is preferably smaller than 100 mm 2, in particular smaller than 50 mm 2. The surface area of an opening is therefore so small that plant soil cannot be flushed out of the plant pot without special circumstances.
    In a preferred embodiment, the openings are in each case at most spaced apart over the largest opening diameter. With a circular aperture, the aperture diameter is the circle diameter, and with a rectangular aperture is the diagonal between two opposite corners of the aperture. Due to the limitation of the opening distance, a large opening density is achieved and thus the surface area of the openings on the total surface of the sector bottom is kept as large as possible. However, the openings do not have to be too close to each other to ensure sufficient stability of the sector floor.
    The openings are preferably rectangular, in particular square shaped. With a similar opening surface share, a stable structure of the grid-shaped sector bottom is obtained with rectangular openings.
    In a preferred embodiment, openings can also be provided in the channel bottom, in a pattern comparable to the sector bottoms. This in particular improves the aeration of the interior of the plant pot.
    Preferably also at the outer edge of each sector bottom are at least two body or rib portions projecting downwards in the axial direction. The sector bottom floats through these rib sections when placing the plant pot on a flat surface with the rib height above the surface. In this way it is ensured that the sector bottom openings are not closed by the substrate when the plant pot is on a flat surface. The dewatering and watering, as well as the aeration, therefore remain guaranteed even when the plant pot is on a flat surface.
    According to the additional patent claim 8, the molded body has an injection mold for manufacturing the plastic plant pot according to any one of claims 1-7, cams formed integrally with the molded body for realizing the sector bottom openings. Separate inserts or insert pins in the injection mold or the mold body for realizing the openings are completely dispensed with. By dispensing with individual insert pins and the one-part design of corresponding opening projections, the shaped body can be cooled as desired by corresponding cooling channels over the entire surface and everywhere, in particular where necessary and desired. As a result, the injection-molded part of the plastic plant pot is cooled faster and more evenly, so that again the production cycle for injection molding a plastic plant pot is shortened by 10-20%.
    An exemplary embodiment of the invention will be explained in more detail below with reference to the figures.
    Shown is:
    Figure 1 shows a pot bottom of a plastic plant pot, in bottom view, and
    Figure 2 shows the plant pot of Figure 1, in longitudinal section.
    Figures 1 and 2 show a plastic plant pot 10, which is provided with a cylindrical circumferential wall 12 and a pot bottom 14 which is circular in plan view. The pot bottom 14 is shown in top view from the outside in Figure 1.
    The pot bottom 14 has three radial and downwardly open channels 16, which converge in the center of the pot in a central region 18. Between the three radial channels 16, which are at an angle of 120 ° to each other, are three sectors 21, 22 23, which are separated from each other by the channels 16 and have flat sector bottoms 25, 26, 27 lying in a lower plane.
    The three radial and downwardly open channels 16 each have a channel bottom 30, 31, 32, which lies in an upper surface. The designations 'upper surface' and 'bottom surface' relate to the plant pot 10 of figure 2, in which the plant pot 10 with the pot bottom 14 stands on a flat surface 15.
    Each sector bottom 25, 26, 27 is screen-shaped over the entire surface and has a plurality of uniform square openings 40.
    Four rib portions 44 are provided on the outer edge of each sector bottom 25, 26, 27, which ribs project downwards in axial direction from the relevant sector bottoms 25, 26, 27. The four rib portions 44 of a sector bottom 25, 26, 27 form between them each time three passages 45 for water and air, when the plant pot 10 stands on a flat surface 15, as shown in figure 2.
    Each radial channel 16 is bounded by vertical side walls 17. The central region 18, into which the channels 16 open, each has three sector slopes 48, each of which extends from the plane of the sector bottoms 25, 26, 27 to the plane of the channel bottoms 30, 31 32 extend. The central region 18 comprises not only one central opening 50, but also the space bounded by the sector slopes 48.
    The central opening 50 is relatively large and has a three-stranded star-shaped injection-rod set 52.
    Four openings 57 are provided in each of the channel bottoms 30, 31, 32, which openings serve primarily for aeration of the interior of the pot, and therefore form ventilation openings. A rectangular opening 58 is also provided in the sector slopes 48.
    The pot bottom 14 of the preceding plant pot 10 has a diameter of 85 mm. The difference in height between the lower surface and the upper surface is approximately 4 mm. The width of the channels 16 is approximately 14 mm. The openings 40 in the sector bottoms 25, 26, 27 have dimensions of approximately 4x4 mm. The central opening 50 has a diameter of approximately 10 mm.
    The sector bottom openings 40 are approximately 4-5 mm spaced apart in cross-sectional direction. The sector bottom openings 40 occupy more than 20% of the sector bottom surface, whereby the outer edge, in which the rib portions 44 are located, is not included.
    The production of the plant pot takes place in the injection molding process. With regard to the pot bottom 14, the injection mold is easy to manufacture and is designed: in the injection mold body, only projections 40 are provided for the sector bottom, which are designed as a whole in the relevant mold body. Because corresponding insertion pins in the injection mold are dispensed with for realizing the openings, the injection mold can be provided with corresponding cooling channels over the total surface of the sector floor, in particular also in the area of the projections or sector floor openings 40 Due to the improved coolability of the injection molded mold provided with opening cams, injection molding and in particular cooling is hereby considerably promoted and made reliable.
