Carton Reinforcing Wings Superposition Impact Resistance

The patent transitions from a conventional single-layer carton structure to a multi-layer superposed structure by adding reinforcing wings that fold over and superpose on the carton walls. This dimensional transformation creates multiple protective layers without requiring a completely new carton design, thereby improving impact resistance while maintaining manufacturing simplicity

The carton is divided into functional segments: the main carton body and separate reinforcing wings. These wings can be independently folded and superposed to create multiple layers of protection at critical areas (flanks and upper side), allowing targeted reinforcement without strengthening the entire carton uniformly, thus improving cost-effectiveness

Instead of making the entire carton more rigid (which would increase overall material costs), the patent applies reinforcement locally at the flanks and upper side through superposed wings. This localized quality enhancement provides impact resistance where it is most needed during transport while keeping the rest of the carton structure simple and cost-effective

The patent creates a composite protective structure by superposing multiple layers of carton material (the base wall and the folded reinforcing wings) to form a multi-layer composite at critical areas. This composite structure provides enhanced strength and impact resistance comparable to more rigid cartons, but achieved through layering rather than using more expensive rigid materials throughout
