Definitions

• the invention relates to a planter made of random fiber fleece, which consists of a bottom part and a vessel wall arranged thereon and as is required in plant breeding, forestry and horticulture.
• Planters made of random fiber fleece have become established because of the rationalization effects that can be achieved in this way when growing plants and when trading such products.
• the rootable and rotten material of the planters saves the need for repotting and prevents root ball damage.
• the planters When producing and handling the planters, the planters are inserted into each other for reasons of space and transport and must be separated for everyone.
• the object of the invention is therefore to provide a technical solution with the aid of which it is easier to separate the planting containers made of random fiber fleece and the stability of the planting container is increased.
• the task is essentially characterized by the features of the
• Vessel wall at least three axially aligned and on the circumference of the
• Planters are advantageously arranged approximately equally distributed ribs.
• the ribs are preferably formed over the entire length of the side
• Vessel wall arranged.
• the ribs are bead-shaped
• the process for producing the planter provides for a raw mat made of random fiber fleece to be formed into a planter between shaping matrices and press dies and, if appropriate, to be stabilized by curing the binder contained in the random fiber fleece. At least three axially arranged grooves are formed in the outer wall of the press ram or in the wall area of the die. During the pressing process, material of the random fiber fleece is displaced into these grooves to form an adequate longitudinal bead. As a result, a planter is obtained which has at least three longitudinal ribs with a bead-shaped cross section either on the inside or on the outside wall of the planter.
• At least three indents which are approximately axially aligned and approximately equally distributed on the circumference of the planter are arranged on the wall of the planter made of random fiber fleece. These indentations serve for the partial support of the bottom edge of the planter when the planters are stacked. At the same time, they prevent the planters from sliding further into one another and the flat contact between the inner and outer walls of the stacked planters, which prevents unstacking.
• the indentations are designed such that the support surfaces and the support surfaces are designed as flat surfaces and are predominantly arranged in the lower third of the wall of the planter.
• the support planes of the indentations are inclined at least 2 ° more with respect to the floor level than the vessel wall of the planter to the floor level. This has the effect that the support edges of the indentations, which are designed in the form of a chord, enclose a circle with a diameter which is smaller than the diameter of the circle enclosed by the bottom edge.
• the base of the planter has an all-round upstand.
• This upstand on the one hand, the desired increase in stability of the bottom edge and, on the other hand, the secure support of the bottom of the planter on the support levels of the indentations is ensured.
• the upstand between the vessel wall and the vessel bottom is designed approximately at an angle of 45 ° with respect to the inclination of the vessel wall.
• the shaping of the indentations is achieved in that at least three approximately axially arranged indentations in the form of flat support and support surfaces, which are connected at an indentation edge, are preferably formed in the outer wall of the press ram and in the wall area of the die.
• the raw mat made of random fiber fleece is shaped between the shaping matrices and press punches by appropriate material densification and / or by the stabilizing effect of hardening binders.
• the proposed edging of the circumferential bottom edge of the planter is also achieved by an appropriate design of the press ram and die.
• the stabilizing support ring ensures that despite the partial support of the bottom of the planter on the support levels of the indentations, there is no deformation of the planter.
• the stacking of planters made of random fiber fleece is advantageously made possible.
• a variant can be used in which the contact between the planters is limited to the lines of the supporting ribs.
• the vessel edge formed in the upper region of the vessel wall as a firmly pressed stable edge which has a larger diameter than the largest diameter dimension of the vessel wall.
• the diameter of the edge of the vessel should preferably be enlarged at least twice the thickness of the vessel wall than the largest diameter of the vessel wall.
• the lower edge of the container rim thus formed serves as a supporting edge when stacking the plant containers, the lower edge of the container edge resting only on the upper edge of the container edge of the previously stacked container. The contact area to the next stacked vessel is thus reduced to a minimum. This contact area is further reduced by the formation of knobs on the lower edge of the rim of the vessel.
• the formation of the circumferential reinforced vessel edge with the formation of a supporting edge is carried out by the appropriate formation of the press ram and the die.
• the planter By pressing the edge material of the blank into the reinforced rim of the vessel, the planter can be shaped in one operation without any further trimming processes.
• the shape of the container wall is frustoconical or approximately hemispherical.
• Figure 1 shows the schematic longitudinal section through a planter with axially arranged inner ribs.
• FIG. 2 shows the schematic plan view of a planter with three inner ribs evenly distributed on the circumference of the vessel wall
• FIG. 3 shows the schematic longitudinal section through a planter with three axially arranged indents
• FIG. 4 shows the schematic plan view of a planter with three indents distributed uniformly on the circumference of the vessel wall
• FIG. 5 shows the schematic longitudinal section through a planter with a hemispherical vessel wall and a sturdy vessel rim with a supporting edge
• Fig. 6 shows the schematic longitudinal section through a planter with a truncated cone-shaped vessel wall and a stable vessel edge with a supporting edge.
• a planter consists of a shaped random fiber fleece made of coconut fiber. According to FIGS. 1 and 2, it has, in addition to a bottom, a frustoconically shaped vessel wall which is formed thereon. Due to the corresponding shape of the ram, ribs 3 are formed on the inner wall of the planter which are offset by approximately 120 ° and have a bead-shaped cross section. When these planters are stacked up, there is only contact between the three longitudinal ribs of the outer vessel and the unprofessional frustoconical outer wall of the inner vessel. When unstacking, the toothing between the individual fibers in the region of the contact lines along the ribs formed must now only be overcome, for which purpose only a comparatively small amount of force is required.

• These indents 6 each consist of support levels 8 and support levels 9, which are connected to each other at a feed edge 10.

• the bottom edge 7 of the bottom 11 of the planter 1 is also equipped with a stabilizing upstand 12.

• Planter 1 in the exemplary embodiment has an inclination of 85.7 °.
• Upstand 12 of the bottom edge 7 was made at an angle of 45 °.
• a planter consists of a shaped random fiber fleece made of coconut fiber. 5 and 6 and, in addition to a base 11, it has a vessel wall 2 integrally formed thereon with a stable vessel edge 13. Due to the corresponding shape of the press ram and the die, the vessel wall 2 is hemispherical as in FIG. 5 or as in FIG. 6 frustoconical to exclude the contact surfaces on the vessel walls 2.
• stable vessel edge 13 is arranged, the outer diameter of which is at least twice the dimension of the vessel wall thickness compared to the largest diameter dimension of the vessel wall. This forms a lower edge of the edge of the container, which serves as a support ring 14 when the plant containers 1 are stacked.
• the contact surfaces during stacking are limited to the upper edge and the support ring 14 of the vessel edges 13 of the planting vessels 1 arranged one above the other during stacking.
• the area contact can be reduced to point contacts.
• the edge of the vessel 2 should be stable, which is achieved by a press molding which takes place simultaneously during the shaping process of the planters. Due to the shape of the die and the press die, which corresponds to the desired final shape of the edge, the edge area of the blank is pressed into the desired shape and a stable peripheral material-reinforced vessel edge is formed without having to resort to additional cutting tools. Hence a clean shape of the rim of the vessel. When using simple shaping tools, the edge can be trimmed cleanly by arranging additional cutting tools during the shaping process. It is important to achieve a clean upper edge surface in order to keep the interlocking of individual fibers as low as possible when stacking.
