Ergonomic handle for container
Patent published on the 2026-06-04 in WO under Ref WO2026115505 by SILVA OLIVEIRA PEDRO MIGUEL [PT] (Silva Oliveira Pedro Miguel [pt])
Abstract: The present invention relates to a handle for containers, more precisely for carboys containing liquids, manufactured from the same material as the container, specifically polyethylene terephthalate (PET), and which is coupled to the neck of the container. Traditionally, carboy handles are made of high-density polyethylene (HDPE) due to its strength, but this makes recycling difficult, as there are components of different materials that must be separated beforehand. The present invention solves [...]
Our summary: The invention presents an ergonomic handle for liquid containers made from polyethylene terephthalate (PET). It addresses recycling challenges associated with traditional high-density polyethylene (HDPE) handles. The design includes a grip and rim for secure attachment to the container neck.

Abstract: Currently, the possibility for the high-value utilization of abandoned oyster shells in the Zhuhai&ndash;Macao region of Guangdong Province, China, lacks sufficient attention, leading to resource wastage. Most oyster shells are treated as kitchen waste or directly landfilled, and their potential cultural and material value is not fully realized. To address this issue, this study explores sustainable utilization pathways for local abandoned oyster shells from the dual perspectives of envi[...]
Our summary: This study explores the sustainable use of abandoned oyster shells in Guangdong Province, China, focusing on ecological and cultural perspectives. It develops a 3D printing material from oyster shells and designs incense holders inspired by local marine culture.
