This invention introduces a new kind of paper container—such as a cup, bottle, or lunch box—that’s not only eye-catching but also durable and functional. Traditional paper containers sometimes include cut-out shapes or windows to make the packaging more attractive. However, these windows often weaken the structure, causing the container to bend or collapse, especially when holding liquids.
To solve this, the inventors created a unique design that uses a combination of solid and hollow sections to form logos or graphics. These hollow sections act like windows, letting consumers see inside the container (for example, to view the color of a drink), while the solid sections keep the overall structure strong. A waterproof and see-through layer covers these cut-outs from the inside or both sides, so the container stays leak-proof and sturdy.
The design supports creative branding—text, logos, or even pictures of plants or animals can be shaped directly into the container. Special color coatings on the solid parts further enhance the look. Importantly, these creative elements don’t weaken the container, thanks to narrow connectors that securely anchor the design to the paper layer.
The key inventive step here is the integration of decorative windows with reinforced solid structures, sealed by waterproof layers. This approach balances visual appeal with strength, unlike previous designs that sacrificed one for the other.
