Definitions

• the present invention relates to the field of nursery gardening, and more specifically relates to a container for nursery plants, particularly adapted to transport, store, maintain, cultivate, and grow plants during the temporary placement thereof before the positioning in the final destination thereof, such as setting them in the intended soil, for example.
• the container firstly should ensure an increased capacity for oxygenation/aeration of the plant roots. This is usually obtained by providing specific, variously located and obtained holes on the structure of the pot; there are varied choices: from positioning them only on the bottom to the side positioning thereof or the positioning thereof along the grooves of the pots or at the feet, or solutions combining those indicated.
• Such holes should also allow the correct drainage of the excess water and the products usually employed during the cultivation of the plant (for example liquid fertilizers) so as to avoid the formation of persistent moist areas which could result in the roots rotting.
• a further important feature of the container should be that of being able to prevent the roots from spiraling; such a spiraling indeed results in suffering of the plant, which is forced in the growth thereof inside the rigid rope created by the spiraling itself, with negative effects not only on the growth, but also on the possibility thereof to survive and correctly develop once repotted or set in the soil.
• such containers should also be easily stackable on one another to simplify both the steps of warehouse storing and product handling, and therefore to allow for example a reduction of the transport volumes thereof, thus reducing the related costs. Therefore, in addition to effective geometries to meet the technical requirements which are indispensable for the intended functions, at the same time the containers also need to have shapes which allow them to be easily stacked, a sufficient lightness to reduce the transport costs thereof and simplify the handling operations thereof, as well as finally a sufficient rigidity, especially in the vicinity of the pot edges, to ensure the safe handling, also by means of forklifts, without accidental breaks occurring.
• Containers for nursery plants having various shapes and which have one or more of the contrivances listed above are available on the market.
• solutions are known from the prior art such as those described in documents EP 2 570 023 A1 , WO 2006/016100 A1 ; WO 2016/100854 A3; US 1 047 0376 B1 ; WO 2018/229486; US2020/0008365 A1 ; US2020/0128759 A1 ; and EP 3 047 723 A1 .
• Document DE202014005009 describes a plastic flower pot provided with sliding elements prepared on the surface of the inner wall to promote the sliding properties in an injection molding process.
• the pot in hand provides a profile on the inner side walls provided with sliding elements, made from a plurality of longitudinal ridges alternated by recesses which create a design with corrugated development on the inner wall of the pot.
• sliding elements serve the function of promoting the sliding of the material injected during the molding process.
• the pot is externally provided with a smooth wall.
• the pot has a base with feet and a middle-raised portion. There are holes for draining liquids both on the raised portion and on the feet. The presence of holes even on the feet of the pot results in a stagnation of water in such a support area, thus creating possible rotting of the roots in that portion.
• the solution proposed in document EP1527676 relates to a pot having a bottom provided with a recess located almost centrally, having one or more openings for draining liquids to avoid stagnation on the bottom following watering.
• Such pots are particularly effective for epiphyte plants, such as Phalaenopsis orchids, for example.
• the roots are raised off the bottom and rot is avoided, however the peripheral edge which serves as continuous foot highly limits the aeration of the roots, given that there are no openings for air exchange.
• pots provided with feet and draining openings.
• the pots comprise angled recesses arranged radially around the bottom portion of the pot for engagement with corresponding angled protrusions on a tray.
• Such elements serve to obtain a correct self-alignment of the pot on the tray.
• the shape of the bottom of the pot i.e., the profile thereof and the reduced thickness thereof, create tearing problems in the anti-algae sheets on which the pots are put on.
• the object of the invention was achieved by a container as defined in claim 1 .
• the container according to the invention may be employed with any type of plant, allows the growth times thereof to be considerably reduced and, once the plant is repotted or set, it takes root securely and with healthy and immediate growth by virtue of a well-developed root system which has no type of spiraling.
• the system of inner ribbings of the container which serve as a barrier, indeed prevent the spiraling of the roots, thus allowing the root system of the plant to expand longitudinally.
• peripheral root system of the plant therefore is not stressed and the growth of the stem is faster and more vigorous than that of normal nursery pots or even of the plants generated outdoors.
• the container of the invention is also easily and affordably moldable and producible, as well as stackable and movable, it is aesthetically pleasing and may even be colored as desired without resulting in defectiveness on the finishing thereof.
• the pot according to the present invention simultaneously solves all the problems of pots of the prior art by providing a pot with anti-spiraling features, with good drainage of liquids, good aeration of the root system and good storage of the antialgae sheet on which the pots usually rest.

• Container 10 comprises a base 20 which defines the bottom of container 10, a truncated cone body 30 which extends upwards from base 20, and a strip gripping portion 40 connected to the upper edge 32 of the truncated cone body 30.
• the truncated cone body 30 comprises a plurality of parallel longitudinal ribbings 34 spaced apart from one another, which extend radially towards the inside of container 10 from the inner wall PI of the truncated cone body 30.
• These longitudinal ribbings 34 on the inner wall PI of container 10 serve to avoid the roots of the plant from spiraling during growth.
• the presence of the longitudinal ribbings 34 promotes the orderly vertical growth of the roots (so-called "primary roots”) and guides the downward growth thereof, that is towards the bottom of the container defined by base 20, to make the successive setting of the plant more effective.
• the number of said longitudinal ribbings 34 is never less than 4, preferably is in the range between 6 and 26, more preferably is in the range between 8 and 24.
• Said number of ribbings is a function of the capacity of the pot, preferably the number of ribbings/liter varies from 0.1 to 8.
• the longitudinal ribbings 34 are also equally spaced apart from one another.
• the longitudinal ribbings 34 extend from the upper edge 32 of the truncated cone body 30 and end at the height of base 20, but in alternative embodiments, they could also be shorter and be positioned differently along the vertical comprising them.
• Said longitudinal ribbings 34 preferably have a width between 0.5 and 4 mm, more preferably about 1 mm, and a depth between 0.5 and 5 mm, more preferably about 1 mm.
• depth of the longitudinal ribbings 34 means the dimension of the distance between the contact point of the ribbing on the inner wall of the pot and the end thereof taken in the direction pointing towards the centerline axis of the container.
• the protruding longitudinal ribbings 34 are arranged on the inner wall of the pot, alternated by intermediate curvilinear portions 35 of inner wall PI, with are recessed with respect to the protruding longitudinal ribbings 34.
• the number of longitudinal ribbings 34 is a function of the capacity of the pot (larger pots will have a greater number of longitudinal ribbings), but it is in any case apparent that the longitudinal ribbings 34 occupy a small part of the inner wall PI.
• the curvilinear portions 35 have a width which goes from a minimum of 30 mm up to a maximum of 140 mm, preferably between 35 and 80 mm, even more preferably between 40 and 73 mm, if measured at the height of the upper edge 32 of the inner wall PI of the truncated cone body 30.
• the pot needs to have at least one curvilinear portion 35 with a width between 30 and 140 mm, preferably between 35 and 80 mm, even more preferably between 40 and 73 mm, if measured at the height of the upper edge 32 of the inner wall PI of the truncated cone body 30.
• the width of the curvilinear portions 35 is defined as the curvilinear distance between two adjacent longitudinal ribbings 34, and in particular from the left edge of the first ribbing to the right edge of the second ribbing, i.e., the successive ribbing.
• a distance is the portion of circumference between the end of one ribbing and the beginning of the successive ribbing, and is not the rectilinear cord which joins two adjacent ribbings.
• the distance between two adjacent longitudinal ribbings 34 is in the range between 30 mm and 140 mm, preferably between 35 and 80 mm, even more preferably between 40 and 73 mm, when measured at the height of the upper edge 32 of the inner wall PI of the truncated cone body 30.
• the distance between two adjacent longitudinal ribbings 34 (or alternatively the width of the curvilinear portions 35) at the bottom of the truncated cone body 30 may be slightly less due to the narrowing of the pot towards the bottom, it being a truncated cone body.
• the protruding longitudinal ribbings 34 obtain discontinuities of the inner wall PI and the distance between two adjacent longitudinal ribbings 34 is such as to perform the anti-spiraling task. Therefore, in addition to the dimensions (width and thickness) of the longitudinal ribbings 34 themselves, the interval or frequency with which they are obtained on the inner wall of the pot is also very important.
• Solutions providing too few longitudinal ribbings or adjacent ribbings which are too far from one another are not effective and the roots spiral all the same. Conversely, solutions which provide too many longitudinal ribbings or adjacent ribbings which are too close to one another risk creating a sort of concentric and "continuous" second inner surface in which the root does not perceive the presence of interrupting ribbings which are an obstacle for spiraling.
• the inventors of the present invention have thus discovered that a distance between the ribbings between 30 and 140 mm, preferably between 35 and 80 mm, even more preferably between 40 and 73 mm, intended as width of the curvilinear portions 35, as better specified above, allows the desired anti-spiraling effects to be obtained.
• Container 10 also has longitudinal flaps 90 in the bottom portion 20, which extend radially towards the inside of container 10 from the inner wall PI of the lower portion 38 of the truncated cone body 30. Said longitudinal flaps 90 also serve the purpose of acting as barrier for spiraling and promoting the orderly and longitudinal growth of the roots.
• outer wall PE of the truncated cone body 30 is a "substantially smooth" flat wall, devoid of holes or side windows.
• the aeration of the root system is therefore obtained by suitably sizing the surfaces of the holes located on the bottom of the container, as better detailed below, while keeping the surface of the outer wall PE devoid of holes or side windows.
• substantially smooth wall should mean a regular and uniform wall in which the possible presence of grooves, ribbings, projections, or roughness does not exceed the depth of 1 mm.
• the outer wall PE of container 10 may be colored and decorated as desired without resulting in defectiveness on the finishing thereof by virtue of the fact that the outer wall is flat, substantially smooth, and therefore devoid of irregularities.
• aesthetical finishing of the sandblasting, photogravure or various polishing type may be applied to the whole outer surface of the pot or parts thereof, such as only on the gripping band 40 thereof, for example.
• said outer wall PE of the truncated cone body 30 of container 10 is smooth and devoid of irregularities also allows the container to be produced with a simple molding operation.
• having the outer wall PE of the truncated cone body 30 of container 10 substantially smooth makes the container easily stackable and movable, both manually and employing forklifts.
• container 10 substantially is circular in cross-section.
• Embodiments in which container 10 substantially is square in cross-section may also be provided.
• the truncated cone body 30 comprises an upper portion 36 and a lower portion 38 which connects said upper portion 36 of the truncated cone body 30 to base 20.
• a lower portion 38 has a smaller diameter with respect to said upper portion 36.
• the base 20 of container 10 is formed by an inner disk portion 22 which is concentric to an outer circular crown portion 24, which are placed on two different parallel planes and therefore at different height from the ground, and are connected to each other by means of a connection portion 23 which provides an inclined sliding wall.
• Said outer circular crown portion 24 and said connection portion 23, which provides an inclined sliding wall, are interrupted by the openings 80 defined below. Therefore, under the condition in which the pot rests on base 20 thereof, the inner disk portion 22 is raised with respect to the outer circular crown 24 and is facing the upper opening or mouth 50 of container 10.
• Said inner disk portion 22 is raised at least 8 mm from the ground. Preferably, it is raised by a value between 8 and 78 mm according to the capacity of the pot; conventionally, the higher the capacity, the higher such a value.
• capacity means the capacity of the container, i.e., the volume thereof, expressed in liters.
• the value of the ratio between the capacity of the container (expressed in liters) and said raised value, which corresponds to the internal height of foot 70 defined below (expressed in mm), is between 0.07 and 1 .60 liters/mm.
• said inner disk portion 22 is raised allows and facilitates the aeration of the roots, thus contributing to the health of the root system.
• base 20 comprises, on the inner disk portion 22 and on the connection portion 23 thereof, a plurality of openings 60 and 62 for draining water.
• the draining openings 60 are obtained at the inner disk portion 22 and the draining openings 62 are obtained at the connection portion 23 which provides the inclined sliding wall.

• the overall surface of the openings 60 and 62 in general increases as the capacity of the pot increases.
• Said preferred surface values allow an optimal aeration of the root system and effective drainage of water and the fertilizers or of the other additives employed, to be obtained, thus avoiding the stagnation thereof in the roots as well as again ensuring the correct structural support for the pot and the right support for the plant therein contained.
• the openings 60 obtained at the inner disk portion 22 are arranged on circular sectors 25 and there are three substantially rectangular windows 60a, 60b and 60c for each circular sector 25 in the embodiment shown.

This to avoid the formation of persistent moist areas which could result in the roots rotting.
• Said feet 70 are preferably 3 to 8 in number, more preferably there are 4 in number. Said feet advantageously also have a width between 1 and 10 cm, preferably between 2 and 7 cm according to the capacity; such a width of the feet 70 allows them not to be deformed over time and not to perforate the antialgae sheet on which they usually rest and which in ordinary use, is subject to perforation precisely in the vicinity of the support points of the container due to their weight.
• width of the feet should mean the dimension thereof, taken in the radial direction, i.e., from the outer circumference of the container towards the centerline axis.
• said feet have beveled corners so as to further reduce the possibility of said antialgae sheets being perforated.
• the feet 70 also result in the presence of the openings 80 at which the two upper 36 and lower 38 portions of the truncated cone body 30 are connected to each other by means of a connection portion 37.
• the upper portion 36 seamlessly joins with the lower portion 38 of the truncated cone body 30 at the feet 70. Therefore, where there are no openings 80, the truncated cone body 30 continues up to base 20 and joins with the outer circular crown portion 24 by means of a connection portion 39.
• the openings 80, which make the feet 70 form interruptions in the outer circular crown 24, thus obtaining circular sectors 26 which make the feet 70.
• the measurement of the width of said openings 80 is particularly important because it also determines the passageway of the gap and therefore, the extent to which it reaches the root system.
• the dimension of these openings 80 measured along the outer circumference of the container and along the lower base thereof (that is in contact with the soil) varies according to the capacity of the container, between 25 and 170 mm, preferably between 30 and 160 mm.

• Openings 64 for draining water are prepared in container 10, on the upper closing ridge 84. In the embodiment shown, for example in Figure 3, there are two openings 64 in the form of substantially rectangular windows for draining water on each inclined circular sector which forms the upper closing ridge 84.
