Hermetic ice tray has weak line for tearing tray into individual cube packages each including one cavity

摘要

The tray defines multiple cavities that are filled with water. A laminar material hermetically and individually seals the cavities. The tray has a weak line for tearing the tray along rows or columns such that cube packages, each including one cavity, are produced. Opening each cube package exposes an aperture. The cube packages are disposable after use.
