GROUNDCROWN, COMPOSTABLE PLANT CONTAINER AND ANIMAL DETERRENT

Abstract

A planter made of PLA, a compostable resin with an element of kelp or a natural fertilizer added in molding. The planter has a crown shaped top edge, the mild points of which serve as a deterrent to animals walking on or eating the plant. The planter has slotted sidewalls in the base area that serve as a vent for water flow and for root expansion when directly planted into the ground. The container body is composed of a 100% organic compostable material. The body can be formed as a blend of 30 to 50% organic plastic with the remaining portion being composed of compostable organic material.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 is a front elevational view of a Ground Crown compostable plant container and animal deterrent, according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0017] FIG. 1 is a front elevational view of a Ground Crown compostable plant container and animal deterrent 100 (hereafter referred to as planter 100) formed of PLA and compostable material. Here, the planter 100 has a container body which includes a base portion 10, a crown portion 20, and a bottom wall 14, and thereby forms an enclosure having an interior space 40.

[0018] The base portion 10 includes a side wall 12. The side wall 12 has a plurality of parallel, evenly spaced slots 16. The crown portion 20 has a side wall 22, a plurality of tips 24 and a plurality of recesses 26 separating the tips 24. The bottom wall 14 has an opening 30 therethrough to permit drainage.

[0019] The planter 100 of FIG. 1 in the preferred embodiment is composed of a mixture of PLA and organic material. The PLA is a compostable resin very much like plastic in appearance, which will allow the planter 100 to serve as a durable container for the life cycle of the plant and have the feature of decomposing in the ground. The planter 100 preferably includes a portion of kelp or a natural fertilizer added to the PLA material in the molding process. This would give a natural fertilizer as the plant grows in the ground.

[0020] PLA, poly or polylactic acid or polylactide, is a biodegradable and bioactive thermoplastic aliphatic polyester derived from renewable resources, such as corn starch, cassava roots, chips or starch, or sugarcane.

[0021] The openings 16 in the base portion 10 and the opening 30 of the bottom wall 14 serve as a vent for water flow so that the plant will not be waterlogged. These openings 15 and 30 will also accommodate root expansion when directly planted into the ground.

[0022] The Ground Crown I Compostable Planter serves to eliminate need for non-biodegradable plastic typically used for pots in the garden industry. The Ground Crown Compostable Planter of the present invention will, within a season in the ground, decompose into the soil. The garden industry will benefit from having a semi durable product that will be eco-friendly in the worldwide market. The Ground Crown Compostable Planter is attractive enough to use for the retail sales and durable for shelf life. The end user will have more success with their plants as it will assist with water retention, serves as an animal deterrent, and permits root growth with the benefit of natural fertilizer as the planter 100 decomposes. The Ground Crown Compostable Planter therefore leave no carbon footprint for the garden industry.

[0023] The container body is composed of 100% organic plastic material. This encompasses both Hemp Plastic and PLA, and contemplates all future materials that have properties similar to conventional molded plastics and which are also compostable and biodegradable. The thickness of the container body is relatively thin so as to facilitate composting, but is sufficiently thick so as to be sturdy enough to hold the plant during the growing/selling season. For example, container wall thicknesses are preferably in a range of 0.20 inches to 1.5 inches; thicknesses outside this range will also work. The preferred thickness in the preferred embodiment is one-eighth inch thickness.

[0024] The container body is composed preferably of a blend of 30 to 50% Organic Plastic (such as PLA or Hemp) with the remaining portion being composed of compostable organic material selected depending on the stability of the material used. Such compostable organic material would include paper, leaves, and other biodegradable compostable materials which would be known to any one having skill in the composting arts.

[0025] Materials suitable for forming the container 100 of the present invention would be a blend of polylatic acid (PLA) and polyhydroxalkanoate (PHA) and 50% to 25% Vinnex powder and or resin (vinyl acetate based homo-co- or terpolymers.) Vinnex has been known to blend with organic and inorganic fillers for tear resistance and stiffness. The supplier Wacker company (having a site wacker.com) has the technology and the art to produce this product.

[0026] As noted in the Wacker company site, biodegradation of TPS/PLA/VINNEX blends under industrial composting conditions (ISO 14855 of EN 13432). On a relative basis with cellulose as the reference substrate, values of 90.0% and 90.1% were calculated. As such, the 90% biodegradability criterion was reached in 65 days both on an absolute and on a relative basis.

Types of materials include:

[0027] Bio plastic: polyhydroalkanoate, or PHA. PHAs; Bio based drop ins: bio-polyethylene (PE), bio-polypropylene (PP) and bio-polyethylene terephalate (PET);

[0028] Fossil fuel based plastics: polybutyrate (PBAT) and polycaprolactone (PCL);

[0029] Alternatively, hemp plastic materials are a suitable match for materials and molding.

[0030] The invention being thus described, it will be evident that the same may be varied in many ways by a routineer in the applicable arts. Such variations are not to be regarded as a departure from the spirit and scope of the invention and all such modifications are intended to be included within the scope of the claims.
