BACKGROUND OF THE INVENTION

Field of the Disclosure

The present invention relates in general to pots and, in particular, to a system, method and apparatus for stackable pots for plants.

Description of the Related Art

Berry plants, such as blueberry plants, are well suited for growth in a container due to their shallow root system that allows swift adaptation to reduced space. Blueberry roots are fibrous and have a small extension, and since they do not have hairs, the younger roots are the ones responsible for nutrients intake.

Another reason for growing blueberries in containers is that they require a specialized soil with a low and acid pH ranging between 4.5 and 4.8. With in-ground plantings, maintaining this low pH may require a concerted, ongoing effort, whereas by using a container or pot it is possible to create the ideal soil pH at planting time.

One method of growing in containers uses a pot described in U.S. D 426,490, which provides a square pot, not showing any particular benefit for blueberries since its flat base is in direct contact with the ground. U.S. D 415,065 discloses a pot of square structure with an upper peripheral border and vertical parallel bars equidistantly distributed over its outer sidewalls. This pot does not showcase a drainage system effective enough for blueberry growing. U.S. D 466,829 discloses a pot of irregular square body with an independent element capable of being assembled in the base by way of a clamping system. In spite of exhibiting square structures, these pots do not have a base adequately engineered to allow proper packing and transportation. Furthermore, these pots are not favorable for high density blueberry production since they do not display space enough between the base and the ground thus preventing an efficient drainage of liquid waste produced as a consequence of plant growing. Improvements in plant-growing containers continue to be of interest.

Referring now to FIGS. 16-19, other embodiments of a container 321 may include a round shape with a tiered bottom. These embodiments may utilize any of the features or elements described for the other embodiments. For ease of reference, the reference numerals of the rectangular embodiments essentially track the reference numerals of the round embodiments, other than being in the 300s.

For example, container 321 can have at least one type of drain hole, and is illustrated with two types of drain holes 335, 337. In some versions, at least some of the drain holes 335, 337 may be located at at least two different vertical elevations with respect to the axis 323 (FIG. 18). In the illustrated embodiments, the interior bottom 339 is not completely flat. For example, the interior bottom 339 may be tapered, tiered, terraced, pyramidal, conical or still other shapes. In one example, a highest elevation of the interior bottom 339 may be at the axis 323. In another example, a lowest elevation of the interior bottom 339 may be adjacent the sidewall 327.

Embodiments of the first type of drain hole 335 may include circular drain holes. The first type of drain hole 335 an be located in the base 325. A version of the first type of drain hole 335 may include a plurality of holes, which may be configured in circular arrays, as shown. In an example, the circular arrays may be concentric. In another example, the circular arrays may be located at different vertical elevations with respect to the axis 323.

Embodiments of the second type of drain hole 337 may include slotted drain holes. Versions of the second type of drain hole 337 may include elongated rectangles configured in a radial array from a central portion of the base 325 to the side wall 327. In addition, the second type of drain hole 337 may coincide and align with tops of legs 332. For example, the legs 332 may extend from the second type of drain holes 337, and the legs 332 may be complementary in shape to the second type of drain holes 337.

Versions of legs 332 may further include an open structure. For example, as shown in FIG. 16, each leg 332 may include side walls 340, a back wall 342, a foot 344 and an aperture or open face 346 opposite the back wall 342. As shown in FIG. 19, such designs facilitate and enable a first container 321a to receive and be stacked with a second container 321b. For example, legs 332b may extend through the second type of drain holes 337a, such that the side walls 340b, inner surfaces of back walls 342 and feet 344 of legs 332b are visible through open faces 346a of container 321a.

Embodiments may include a square-containing body of four sidewalls with rounded edges. The square body has an open top extreme surrounded by an outer rounded border that is an extension of the containing body, jutting outwards forming such border. In the lower part of the containing body there is a base with a staggered pyramid-like structure of four sides. This structure includes at least three echelons. The first echelon is located adjacent to the edge formed by the lower periphery of the containing body; the second and third echelons are disposed to form a four sided staggered pyramidal structure inside the containing body. At each side of the first echelon and on the surface parallel to the base, are situated at least two equidistant round holes, preferably four holes on this first echelon. At each side of the second echelon and on the surface parallel to the base, there is located at least one round hole, preferably two holes.

At the outer lower part of the base and on each one of the vertices forming the sidewalls of the containing body, there is at least one supporting means, such supporting means has an elongated structure measuring at least 1 cm height. The elongated structure is an extension of the rounded edge of the containing body, preferably three supporting means per vertex. These supporting means are situated parallel to the vertex of the containing body and are equidistant to each other.

Such a structure is suitable for growing blueberries and raspberries in substrate since it prevents the contact between the plant roots and the soil due to the supporting means at the base, preventing exposing the plant to pathogenic agents, also improving drainage and root health. The pot's staggered base reduces the wet zone also, while its shape allows compact packing thus minimizing shipping costs.

Other versions may include a cylindrical body with a top diameter bigger than the diameter at the base. These diameter proportions favor pot transportation allowing stacking multiple pots one on top of another. The upper part of the cylindrical body displays a peripheral border. The base has multiple long slits radially disposed on its outer side. There are preferably 6 long equidistant slits. In the same way, multiple elongated supports can be found at the base, radially and equidistantly located between the slits from 2 to 3 cm height, preferably 6 in number of 3 cm height. The slits and the supporting means are configured in such a way as to allow a free circular area at the center of the base. The free circular area is devoid of slits and supports to provide a more solid structure to the base.

Between a given slit and a support at least one circular hole is located of up to 0.5 cm in diameter. Between each slit and each supporting means there are preferably two holes. These holes allow better drainage of the wastes coming from the substrate growing carried out within the pot's body.

In some versions, at the lower outer periphery of the pot's cylindrical body and adjacent to the base square slots are located of up to about 1 cm². These square slots are distributed following the same line of holes at the base between each slit and each support.

The embodiments described herein may offer substantial technical advantages over prior art container designs. Such designs permit air flow between the base and the ground, thus providing improved conditions for efficient crop production. The base has multiple supporting elements that prevent contact between the plant roots and the ground, thus avoiding exposure to pathogenic agents. The base also has multiple holes to permit efficient drainage of fluids resulting from plant growing.
