Reusable Pods for Sustainable Coffee Brewing

A single-serve coffee brewer that provides a high-quality coffee experience without requiring timed interaction or increased manual dexterity. The brewer uses a novel brewing method and design to overcome the issues of taste, waste, and convenience in single-serve coffee makers. It allows for single-serve brewing without disposable pods, reduces waste by using less packaging, and improves taste by using freshly ground beans. The brewer has a reusable filter basket that holds a measured amount of freshly ground coffee. The brewing process involves immersing the coffee in water at controlled temperatures for a precise time. This extracts the flavor without over-extraction. The brewer also has a mechanism to automatically stop the brewing when complete, preventing over-extraction. The result is a high-quality, customizable single-serve coffee without the waste or taste issues of pods.

A machine for filling and sealing single-serve biodegradable pods with ground food products like coffee. The machine has a rotating platform that moves empty pods to a filling station where augers or valves fill them. Then the pods move to a sealing station where a heated block seals and trims a film lid onto the pods. The machine automates the process of filling and sealing pods to produce single-serve packaged food products.

A coffee capsule that can be filled multiple times with coffee powder and reused, reducing waste and cost compared to disposable capsules. The capsule has a shell to hold the coffee and a sealing film covering the shell opening. A hoop compresses the film edge against the shell to seal it. This allows the capsule to be filled and sealed with coffee multiple times while still fitting capsule coffee machines.

A compostable capsule for preparing hot beverages, like coffee, that is made of a compostable non-crosslinked polysaccharide shell encasing a core of beverage ingredients like coffee powder. The cladding material can be made of polysaccharides like carboxymethylcellulose, microfibrillated cellulose, sodium alginate, pullulan, or chitosan. The capsule provides a compostable alternative to plastic and aluminum coffee pods.

Reusable single-serve coffee pod system that is environmentally friendly and provides a better tasting cup of coffee. The pod system consists of a reusable open-bottomed ring and disposable filters. The filters are biodegradable and can be quickly and easily assembled and disposed of using a dedicated assembly station.

A fully compostable and biodegradable capsule for preparing infusion or soluble beverages like coffee that avoids the environmental issues of conventional capsules. The capsule has a body made of a compostable/biodegradable material and a lid closure made of a compostable/biodegradable material. The key innovation is the lid design that enables the use of compostable materials without sealing problems. The lid has a weakened portion that allows it to be easily pierced by a brewing machine. This avoids needing a sealing layer like aluminum or glue that wouldn't be compostable.

Biodegradable coffee pod system as an environmentally friendly single-serve coffee option. The system comprises a biodegradable pod made of filter material containing coffee grounds, a reusable holder to keep the pod in place during brewing, and a resealable low-waste packaging for transporting multiple pods. The biodegradable pod can be placed in a compatible coffee machine, brewed like a regular coffee pod, and then disposed after use. The system aims to reduce the waste of single-serve coffee pods by providing a biodegradable alternative.

Reusable coffee brewing cartridge for Keurig-type machines that offers an eco-friendly alternative to disposable K-Cups. The cartridge has an injection nozzle like a disposable K-Cup, but instead of an extraction needle that pierces the bottom of the capsule, the reusable cartridge has passageways in the base to release the brewed coffee. This avoids the need for a seal with the machine's extraction needle, which simplifies the design. It also has a color code on the base that can be read by the machine to automatically set the brew parameters.
