Multi-Layer Pouch Diaper Mat for Leakage and Odor Containment

The plastic bag is divided into multiple separate layers (first plastic layer, second plastic layer, third plastic layer) that are sealed together to form distinct pockets. This segmentation creates a multi-chamber structure where each layer contributes to containment, preventing leakage and odor while maintaining structural integrity without requiring a single complex thick layer.

The multi-layer structure creates nested pockets where the first pocket is formed between the first and second plastic layers, and the second pocket is formed between the second and third plastic layers. The layers are sealed together in a nested configuration, with each layer enclosing the previous one, creating a nested containment system that effectively traps contaminants.

The pouch is segmented into multiple functional layers with specific roles: the first plastic layer provides initial containment, the second plastic layer creates intermediate sealing, and the third plastic layer provides external containment. This segmentation allows each layer to address specific aspects of odor and leakage control, achieving comprehensive protection through distributed functionality rather than a single complex barrier.

Different regions of the pouch structure are assigned different qualities and functions. The sealed regions between layers create discrete pockets with specific containment properties, while unsealed regions allow for filling and sealing operations. The absorbent material is localized in specific pockets to address contamination at its source, providing local quality enhancement without requiring the entire structure to be uniformly complex.

The pouch structure employs nested pockets where the first pocket (between first and second plastic layers) and second pocket (between second and third plastic layers) are arranged in a nested configuration. This nested structure creates multiple barriers against liquid feces leakage, with each pocket acting as a containment zone. The nesting ensures that even if one pocket is compromised, the other layers provide redundant protection, significantly enhancing leakage prevention reliability.

The multi-layer pouch structure provides beforehand cushioning against leakage by creating multiple sealed barriers before contamination can occur. The absorbent material is positioned within the nested pockets to absorb liquid feces before it can penetrate through to external surfaces. This prior cushioning through layered containment and absorbent positioning prevents leakage during diaper changing operations.
