Description

 Culture pot for plants

The present invention relates to a culture pot for plants, in particular for orchids or other epiphytes, with an outer pot and an inner, provided with recesses plant pot, wherein between the outer pot and the plant pot a ventilation gap is provided.

Especially orchids are popular ornamental plants that are grown in culture pots according to the preamble of claim 1. Orchids, which belong to the Epiphyten or Aufsitzerpflanzen, form air or light roots. The ventilation gap of the culture pot thus serves to spread these roots in an area that can be irrigated, but can not be filled with substrate. Since good ventilation of the roots is necessary for the growth of the plants, the ventilation gap at the same time also serves for rapid drainage of the water after irrigation, culture pots typically having bottom drainage openings therefor. For example, orchids of the genus Phalaenopsis are popular, which are often bred in coarse substrate such as bark mulch, stones or sometimes also polystyrene hard foam pieces.

Important for the rearing of epiphytes is the formation of a good indoor climate, as these plants thrive best in subtropical or tropical climates. This is realized in a complex manner in the greenhouses, which is associated with corresponding costs.

The present invention is therefore the object of developing a culture pot of the type mentioned in such a way that the production of the necessary for the rearing and growth of a corresponding plant climatic conditions is improved. Furthermore, the invention has the object to provide more space in a culture pot and to improve the arrangement of the plant pot in the outer pot.

This object is achieved by an article according to the preamble of claim 1, which is developed according to the invention according to the characterizing part of the claim. Features of advantageous embodiments of the invention can be taken from the following subclaims and the following description.

According to the invention, it is provided that the ventilation gap is formed only over part of the height of the culture pot and ends below an upper edge of the outer pot, whereby in an upper part of the outer pot compared to culture pots, in which the ventilation gap completely and on all sides to the upper Rim is enough, additional substrate space is provided. With a culture pot formed in this way with an upwardly limited ventilation gap, a running exchange between the ventilation gap and the environment takes place in a reduced amount compared with the prior art. This forms Especially after an irrigation in an area between plant and outer pot a kind of primeval forest climate, which favors the growth of the orchid. Sufficient ventilation is still ensured due to the commonly used coarse substrate and existing drainage holes.

As a result of the development according to the invention, additional space for substrate is available in an upper part of the culture pot. The upper part of the culture pot advantageously extends, starting from the uppermost edge, over at least one tenth, preferably over approximately one quarter of the height of the culture pot. Even larger areas are possible. This not only improves the optical view of a plan view of the corresponding culture pots, it is also a larger supply of memory, for example, by irrigation from the substrate leachable nutrients available.

In an advantageous embodiment of the invention, an upper boundary of the ventilation gap is formed by the outer pot and / or by the plant pot, so that a culture pot according to the invention can be produced in a simple manner. The same applies to a one-piece culture pot.

In an advantageous embodiment of the culture pot is formed in two parts, wherein the outer pot is a particular provided with a grid and / or a lattice-shaped peripheral wall indoor or plant pot is used. For this purpose, a guide for centering the plant pot is provided in the outer pot, so - A - that this is difficult or impossible to tilt and the handling of the culture pot is improved.

Furthermore, the plant pot advantageously has a collar which can serve for centering and / or contact with the outer pot. On the one hand so the centering of the plant pot is ensured by the system on the inside of the wall of the outer pot and on the other hand at the same time a secure fit. The collar is formed for example by a rounding of the wall or as shown below by an angled upper part of the wall.

The collar is further preferably arranged in an upper region of the plant pot, whereby an upper boundary of the ventilation gap between the plant and outer pot is effected.

A good hold of the plant pot in the outer pot is ensured in a further embodiment of the invention by at least one on the inside of the wall of the outer pot existing, possibly circumferential approach, preferably a locking corner or a locking cam. The approach is arranged above an edge of the plant pot, whereby the plant pot sliding over the approach engages in a position below and is secured so latching.

Advantageously, arranged in a bottom portion of the outer pot central elevation, in particular in combination with a laterally flared collar of the plant pot for a guide and centering of the inner pot in the Outer pot provided. Even without the collar is due to the survey, which tapers towards its tip and has a horizontal cross-section to the ground, an optimal centering given centered inaccurate plant pots.

In a particularly advantageous embodiment of a cultivated pot provided with a central elevation, the plant pot is provided with a recess corresponding to the elevation, through which this elevation extends at least partially into one another nesting plant and outer pot. The bottom of the plant pot is thus secured in a direction parallel to the ground by the survey, whereby the ventilation gap does not narrow even with a movement of the culture pot.

In an embodiment with sides running obliquely toward one another and a conically tapering cross section associated with it, a movement of the plant pot in the direction of the bottom of the outer pot is prevented with a corresponding recess. In such an example, truncated cone-like formation of the survey may optionally be waived additional Aufstellfüße or spacers, which are arranged between plant pot and outer pot and either one or the other, if necessary, also assign both parts of the culture pot.

If a particularly stable plant pot is required, for example, when filling the plant pot with stones, spacers or Abstützele- preferably distributed over the underside of the bottom of the plant pot. The spacers are then supported on the bottom of the outer pot, which may also have side ribbed Aufstellfüße or flanges to allow good drainage over, for example, arranged below the bottom of the outer pot drainage holes.

The plant pot is advantageously provided with in particular grid-like recesses of a minimum clear width of 3 mm, preferably with a clear width of 5 mm to 7 mm, which represent a good compromise between the root thickness of an epiphyte and the diameter of the substrate used. Thus, unlike the roots, the substrate is prevented from entering the ventilation gap or space.

Advantageously, the outer pot comprises not only drainage openings, but in particular ventilation openings, which are preferably in ventilation connection with the ventilation gap, without negatively influencing its climate. For this purpose, it is sufficient to provide, for example, in the bottom of the bottom of the pot thin luftgängige columns or other openings.

In order to allow lightworms a particular growth, the outer pot is at least partially made of a transparent material, which should be a natural environment as possible improved for the plants to be displayed. In a further advantageous embodiment, the culture pot has at least one holder for a holding bar. This holder is, for example -in a vertical view- realized by a partial overlap of two recesses, one of the outer pot and one of the plant pot, so that by the edges of the staggered openings, for example in the region of the central elevation or the ventilation gap, support rods for the Flower stems can be guided in the culture pot and held sideways. In another embodiment, a retaining bar may be retained by a recess in the collar of the plant pot and a recess in a lower portion, the retaining bar extending through the venting gap. By a holder according to the invention, the culture pots are already formed transport-safe with already grown plants.

Advantageously, the inner pot is formed of polypropylene. However, it is also conceivable to use the polystyrene provided with a higher modulus of elasticity as an inner pot or plant pot material. The injection-molded plant pot is supplemented by an injection-molded or deep-drawn outer pot.

Further advantages and details of the invention can be taken from the following description of the figures. The individual features described in the figures can in this case contribute in different combinations with their respective advantages to developments of the invention.

Identical or similar acting parts are provided with the same numbers if appropriate.

Fig. 1 discloses a culture pot according to the invention with an outer pot 1 and a plant pot 2, which is inserted into the outer pot 1 and forms a ventilation gap 3 with this. This ventilation gap 3 is bounded at the top by a laterally issued, opposite a lower part of the side wall more angled collar 4 of the plant pot 2. With an edge 5 of the collar 4 is secured via a lug 6, which may be formed as a locking edge or locking cam, the outer pot 1 in its seat in the outer pot 1. Towards the bottom, a bottom 7 of the outer pot 1 defines the ventilation gap 3. The soil 7 or the plant pot is supported by support feet 9 provided with stiffening ribs 8 with respect to a substrate. The indoor or plant pot 2 is supported by its own support 11, which are formed in a similar manner with flanges 14 as the erection feet 9, supported on the bottom 7 of the inner pot 2. In the upper part of the outer pot 1, a substrate space 12 is formed, which is larger due to the limitation of the vertical extent of the ventilation gap 3 by the flared collar 4 of the plant pot 2 relative to the volume of the culture pot than in conventional culture pots.

In an upper region of the plant pot 2 is centered over the edge 5 of the collar and securely supported against the outer pot 1. By locking the mobility of the plant pot 2 in a lower region, for example in the direction of an edge 13, is reduced.

The plant pot 2 is provided with horizontal struts 16 and with vertical struts 17, which form in the manner of a grid recesses 18 with a minimum clear width of 3 mm, preferably from 5 to 7 mm.

2 differs from the culture pot according to FIG. 1 substantially by a central elevation 21 of the outer pot 1, which is formed like a truncated cone of the bottom 7 of the outer pot 1. Advantageously, at a height of the culture pot of about 12 cm, the survey is about 2 cm high. In the inclined side portions of the elevation 21 ventilation holes or openings are recessed in the form of recesses 22, with the ventilation openings 23 of the upper part of the plant pot 2 and further arranged in the bottom 7 ventilation openings 20 for a sufficient Ventilate the ventilation gap 3 Take care. The recesses 18, which are sufficiently large for the passage of roots of the air rooting used in the plant pot 2, provide with the additional recesses or vents 25 in the bottom 24 of the plant pot 2 for further ventilation of the culture pot located in the plant pot 2.

Due to the central arrangement and the bevel of the side walls of the elevation 21 of the plant pot 2 is centered during insertion into the outer pot 1. The bottom 24 of the plant pot has for this purpose a recess which is large enough to ensure passage of the elevation 21 far enough that the plant pot can stand on its support elements 11. Optimally, the recess is selected so that the side walls of the elevation 21 abut the inner edges of the recess of the plant pot 2 exactly at the moment when the spacers or support elements 11 touch the bottom 7 of the outer pot 1. An edge 27 in the upper region of the outer pot 1 can also be used as gripping edge for holding an outer pot stack during the removal of a lower outer pot 1 from this stack by means of corresponding gripping means.

The culture pot is circular in cross-section as shown in FIG. However, it may also be other, for example, square, provided with a sloping side edge culture pots. The wall of the outer pot 2 is inclined at an angle of 4.5 °, wherein the inclination of the plant pot 2 is greater than the inclination of the wall of the outer pot 1. The resulting therefrom ventilation gap 3 thus tapers upwards, which takes into account the fact is worn that a majority of the roots in a lower portion of the ventilation gap 3 penetrates into this. In the upper region of the plant pot 2, therefore, relatively more substrate can be introduced. The partially overlapping with the recesses in the bottom of the plant pot 2 recesses of the survey 21 form areas 28, in the example, holding rods for holding the flower stems of an orchid can be inserted.

FIGS. 3 and 5 further show that the water, after being irrigated from above, can flow off almost over the entire cross-sectional area of the culture pot, since drainage openings in the form of ventilation openings 22 and 23 or 18 and the recess distributed uniformly over the entire area in the ground 24 are present. Viewed in the cross-section, the proportion of recess to the total cross-sectional area in the plant pot may advantageously be between 40% and 60%. The injection-molded pot 2 produced in the injection molding process, shown in a perspective view in FIG. 4, can be stacked individually over the individual spacer elements 11 at its bottom, the edge 28 and with the underside 29 of the upper part of the collar 6 and the edge 5, respectively that there is a jamming of the plant pots 2.
