Traditional coffee drippers are often made of porcelain, which is heavy and bulky, making it unsuitable for outdoor and travel use, and portability focuses on lightweight, compact, and functionality.
Most portable coffee drippers available on the market are not ideal. For example, a triangular cone dripper with three metal plates is not conducive for controlling coffee extraction and adversely affects flavor. Additionally, the metal material is too heavy. Another type of coffee drippers is integrally made of silicone, which requires sufficient structural thickness for strength and therefore has a considerable weight and large storage volume.
This design combines PP sheet materials with silicone to reduce the use of materials and make PP (which is widely used for disposable food packaging and containers) reusable.
Technically, origami techniques are used to fold a single flat board into a three-dimensional structure with a linked stand. This involves intricate and precise cutting. An innovative heat-etch cutting method is adopted since the 0.6mm thickness of the PP sheet renders traditional cutting tools unusable.
This design is lighter and comes with a heightened dripper holder to prevent the filter paper from getting soaked. It also allows for easy monitoring of water level in the cup, which is beneficial for outdoor use without requiring a transparent glass. The coffee dripper is foldable for flat storage, making it easy to fit inside a backpack."
