COMPOSTABLE COMPATIBILIZERS FOR BLENDS OF BIODEGRADABLE ELASTOMERS AND BIODEGRADABLE THERMOPLASTIC POLYESTERS AND METHOD OF PRODUCTION THEREOF

Resumen de: WO2025146661A1

The invention encompasses compositions of biodegradable polyester elastomers and biodegradable thermoplastic polyesters with enhanced compatibility using compostable compatibilizing agents. The compositions can be used for melt processing purposes such as extrusion, batch mixing, injection molding, and compression molding. In various embodiments, the compositions encompass polymer blends comprised of at least one biodegradable polyester elastomer, one biodegradable thermoplastic polyester, and one compostable compatibilizing agent. The invention allows for tailored compatibility of the composition through direct compounding of the biodegradable polyester elastomer, the biodegradable thermoplastic polyester, and the compostable compatibilizing agent.

REFILLABLE CONTAINER

Resumen de: US2025223094A1

A refillable container for a product for oral consumption is provided, the container including: a refill component; a casing having an access opening at a top end of the casing, the casing being configured to removably receive the refill component through the access opening; and a lid movable between a closed position in which the lid occludes the access opening and an open position in which the lid is displaced to reveal the access opening and enable access to the refill unit, the refill component including a rigid cup-shaped body including a bottom wall and a side wall, the cup-shaped body defining an internal receptacle to accommodate the product, and the bottom wall of the cup-shaped body including a downwardly concave portion, such that when the refill component is received inside the casing a compartment is defined between the downwardly concave portion and a bottom wall of the casing.
