Compostable container for storing fluids
A fully compostable container is provided having an enclosed body with an opening through an interior surface and an exterior surface. The enclosed body having a plant fiber structural layer configured to biodegrade in ambient conditions into nontoxic residue and a fluid barrier layer formed on a first side of the structural layer to form the interior surface of the enclosed body, the fluid barrier layer configured to biodegrade in ambient conditions into nontoxic residue. The container is gradually biodegradable when exposed to a set of factors in a natural environment and has a shelf life of six months when stored under standard commercial conditions.
1. A method, comprising:
forming an ambient biodegradable container having a shelf life of twenty-four months or less, the forming of the container including:
forming an enclosed body having an opening through an interior surface and an exterior surface, the forming of the body including:
forming the interior surface of the enclosed body by covering a first side of an ambient biodegradable plant fiber structural layer with an ambient biodegradable fluid barrier layer, the plant fiber structural layer and the fluid barrier layer configured to degrade into nontoxic residue in ambient environmental temperatures in the range of 20 and 30 degrees Celsius;
forming the opening through the plant fiber structural layer, the opening having a width that is smaller than an average width of the enclosed body; and
manipulating the plant fiber structural layer to form the enclosed body; and
coupling an ambient biodegradable mouth to the opening, the mouth in fluid communication with the interior surface of the enclosed body and configured to cooperate with the fluid barrier layer to protect the plant fiber structural layer from moisture, the mouth configured to degrade into nontoxic residue in ambient environmental temperatures in the range of 20 and 30 degrees Celsius.
2. The method of claim 1 , further comprising:
forming the fluid barrier layer by spraying a resin onto the plant fiber structural layer.
3. The method of claim 1 , further comprising:
forming the plant fiber structural layer by compression molding and curing.
4. The method of claim 1 , further comprising forming the exterior surface of the enclosed body by forming an ambient biodegradable protection layer on a second side of the plant fiber structural layer, the protection layer configured to degrade into nontoxic residue in ambient environmental temperatures in the range of 20 and 30 degrees Celsius.
5. The method of claim 4 wherein the protection layer and the fluid barrier layer have the same chemical composition.
6. The method of claim 4 wherein the protection layer and the fluid barrier layer have distinct chemical compositions.
7. The method of claim 1 , further comprising coupling an ambient biodegradable cap to the mouth to seal the enclosed body, the cap configured to degrade into nontoxic residue in ambient environmental temperatures in the range of 20 and 30 degrees Celsius.
8. The method of claim 1 , further comprising forming the opening after manipulating the plant fiber structural layer to form the enclosed body.
9. The method of claim 1 wherein the shelf life of the container is six months.
10. The method of claim 1 wherein the plant fiber structural layer, the fluid barrier layer, and the mouth degrade into carbon dioxide, water, and benign biomass.
11. A method, comprising:
forming an ambient biodegradable sealable container having a shelf life of about twenty-four months or less in standard indoor storage conditions, the container having an enclosed body and a sealable opening, forming the container including:
forming a water resistant surface by forming an ambient biodegradable fluid barrier layer on a first side of an ambient biodegradable plant fiber structural layer, the structural layer and the fluid barrier layer being configured to degrade into nontoxic residue in ambient outdoor temperatures in the range of 20 and 30 degrees Celsius;
forming the opening through the structural layer and the fluid barrier layer;
manipulating the structural layer to completely enclose the fluid barrier layer within the enclosed body; and
coupling an ambient biodegradable mouth to the opening, the mouth in fluid communication with the fluid barrier layer of the enclosed body to protect the structural layer from moisture, the mouth being configured to degrade into nontoxic residue in ambient outdoor temperatures in the range of 20 and 30 degrees Celsius.
12. The method of claim 11 wherein the container has a shelf life of around six months.
13. The method of claim 11 wherein the plant fiber structural layer, the fluid barrier layer, and the mouth degrade into carbon dioxide, water, and benign biomass.
14. The method of claim 11 wherein the fluid barrier layer is susceptible to degradation with exposure to UV wavelengths and the structural layer and the mouth are not susceptible to degradation with exposure to the UV wavelengths.
