Description

Technical Field

[0001] This utility model relates to the field of paper bowl technology, specifically to a high-strength paper bowl anti-collapse reinforcement structure. Background Technology

[0002] Paper bowls, as disposable food containers, are widely used in daily life due to their convenience. They are typically made from chemically processed wood pulp paper (white cardboard) through mechanical processing and bonding. Because the main body of the paper bowl is made of food-grade paper, traditional paper bowls are relatively thin and have a single-layer structure. They also lack corresponding pressure-resistant support components, making them prone to collapse or deformation when subjected to food weight or external pressure. This not only affects aesthetics but can also cause food spillage, inconveniencing the user. Therefore, we propose a high-strength anti-collapse reinforcement structure for paper bowls.
