• the container can be constructed entirely of a combination of paper or cardboard and biopolymers.
• an entirety of the container is compostable and biodegradable.
• the container achieves an environmentally friendly "look and feel" by minimizing the amount of bioplastic component parts that are visible and by maximizing the visibility of component parts made of water-permeable, biodegradable, and compostable material(s) (e.g., cardboard), all while still maintaining structural integrity of the container and the ability of the container to be filled, sealed, and also resealed.

Accordingly, in this way, the interior volume of the container can be rendered water-impermeable, such that fluid contents are prevented from escaping from the container or being absorbed by the container. Furthermore, despite the water-impermeability of the container (e.g., from the inside), the container as a whole is biodegradable and compostable.
• bioplastics are derived from renewable raw materials like starch (e.g. corn, potato, tapioca, etc.), cellulose, soybean protein, lactic acid, and the like. They are not typically hazardous or toxic in production and are able to decompose into materials such as carbon dioxide, water, and biomass when composted. Bioplastics generally can take different length of times to completely and fully compost, depending on the particular material. Bioplastics conventionally are intended to be composted in an industrial or commercial composting facility that is able to generate high composting temperatures for extended periods (e.g., between about 90- 180 days in some instances).
• compostable is intended to have its normal meaning, as would be appreciated by one of skill in the art upon reading the present specification.
• ASTM American Society for Testing & Materials
• a bioplastic is compostable if it is capable of undergoing biological decomposition in a compost site as part of an available program, such that the plastic is not visually distinguishable and breaks down into carbon dioxide, water, inorganic compounds, and biomass, at a rate consistent with known compostable materials (e.g., cellulose) and if through the process of biological decomposition the bioplastic leaves no toxic residue.
• compostable materials e.g., cellulose
• most existing international standards define "compostable” to include those materials capable of biodegradation of about 60% within about 180 days (e.g., in combination with other criteria).
• the plastic must be: (a) capable of biodegradation, e.g., the break-down into carbon dioxide, water, biomass at the same rate as cellulose or paper; (b) capable of disintegration, e.g., the material must be capable of becoming indistinguishable within the compost, such that it is not visible and need not be screened out; and (c) non-eco-toxic, e.g.j must not produce any toxic material, such that the resulting compost can support plant growth.
• biodegradation e.g., the break-down into carbon dioxide, water, biomass at the same rate as cellulose or paper
• disintegration e.g., the material must be capable of becoming indistinguishable within the compost, such that it is not visible and need not be screened out
• non-eco-toxic e.g.j must not produce any toxic material, such that the resulting compost can support plant growth.
• the amount of time required to compost can change depending on a variety of factors. Commercial composting facilities tend to grind materials being composted and agitate (e.g., stir, turn over, etc.) the resulting piles while exposing the piles to high temperatures. This reduces the amount of time required for the materials to compost. However, composting rates at home composts can be significantly lower and can vary depending on how frequently the pile is agitated (e.g., stirred, turned over, etc.), the moisture of the pile, the contents of the materials forming the pile, the temperature of the pile, and other environmental conditions.
• biodegradable a bioplastic must be capable of degrading as a result of naturally occurring microorganism(s), such as bacteria, fungi, and the like. However, unlike compostability, the quality of not leaving behind a toxic residue is not a requirement for biodegradability.
• biodegradability and “compostability” generally are intended to have their normal meanings and definitions, as would be appreciated by one of skill in the art upon reading the present specification.

• one or more biodegradable, water- impermeable coating materials can be disposed on (a) the interior side of the base 18, (b) the interior side of the top 20, and (c) the interior sides of the one or more walls.
• FIGS. 7 and 8 additionally or alternatively can be implemented for the first bioplastic junction piece 24.
• FIGS. 9 and 10 depict an exploded view and a cross-sectional view, respectively, of an upper end of the container 10 having the first bioplastic junction piece 24 including the first frame member 36 and the second frame member 38.
• the top 20 can be coupled to the first frame member 36, and the one or more walls (at the upper perimeter thereof) can be coupled to the second frame member 38.
• the piece 32b of the bioplastic grommet 30 can be coupled to the second frame member 38 of the first bioplastic junction piece 24, as illustrated.
• the exterior sides of the base 18, the top 20, and the one or more walls can also be coated with one or more biodegradable, water-impermeable coating materials (e.g., PLA, etc.).
• the one or more biodegradable, water-impermeable coating materials can form a water-impermeable lining that, in combination with the cover 28 and the first and second bioplastic junction pieces 24, 26, creates a barrier that prevents water (or other liquid contents) disposed external to the container 10 from being absorbed by the one or more walls, the base 18, or the top 20.
• This can be beneficial, for example, in preventing the container 10 from becoming sodden or soggy, e.g., when placed in a wet environment such as a cooler or other container of ice.
• the container 10 according to embodiments of the present invention can be constructed entirely of compostable and biodegradable components.
• the amount of visible PLA or other bioplastics is small, thereby allowing the container 10 to achieve an environmentally friendly appearance without sacrificing the ability of the container 10 as whole to remain water-impermeable during use.
