Pizza Container With Storage Bags for Hygienic Residue Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pizza containers are large in size, inconvenient to carry, and result in food residues sticking to the container or user's hands during heating or consumption, posing hygiene issues.
Innovation Solution
A pizza container design featuring storage bags with top and bottom walls, a container body, and a lid, where pizzas are stored in bags to isolate food residues, preventing them from sticking to the container or user's hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple trays are stacked layer by layer in the container body, then the container size can be reduced for better portability, but the bottom of upper trays will stick to food residues from lower trays, causing hygiene issues
Solution Approach 1:
The patent introduces a protective film as an intermediary layer between stacked trays. This film prevents direct contact between trays, thereby stopping food residues from sticking to upper trays while maintaining the compact stacked structure. The film acts as a mediator that preserves both portability and hygiene.
Solution Approach 2:
The protective film is designed as a disposable component that is discarded after single use. This allows the system to benefit from the hygiene protection of a barrier layer without the cost or complexity of reusable components, enabling compact stacking while preventing food residue contamination.
2Ease of operation
If ordinary pizza containers are used, then they can hold pizzas, but their large size makes them inconvenient for storing unfinished pizzas or taking them away
Solution Approach 1:
The patent implements a nested structure where multiple trays are stacked vertically within a single container body. Each tray can be placed inside the container, and the container itself can be stored within larger packaging when not in use. This nesting approach maximizes space utilization and portability.
Solution Approach 2:
The pizza container is divided into multiple separate trays that can be stacked, and each tray can be independently removed or stored. The container body is also separable from its outer packaging. This segmentation allows flexible storage and transport, enabling users to carry only the necessary portions.
3Device complexity
If pizzas are stored directly in the container without protective layers, then the structure is simpler, but food residues stick to the container and user's hands during heating or consumption
Solution Approach 1:
The protective film serves as an intermediary barrier between the food and the container/trays. This simple addition prevents direct contact between food residues and surfaces, eliminating contamination issues without requiring complex structural modifications to the container system.
Solution Approach 2:
The patent employs thin flexible protective films that conform to the shape of the pizza and trays. These films are simple to apply and remove, providing effective contamination prevention while adding minimal structural complexity to the overall system.

AI summary
A pizza container includes a container body, a lid, and one or more storage bags. The storage bag includes a top wall and a bottom wall, a storage cavity is formed between the top wall and the bottom wall, the storage cavity includes an opening communicated with outside, and a pizza to be stored can be loaded into the storage cavity through the opening. The container body includes a bottom plate and an enclosing wall surrounding the bottom plate, the bottom plate and the enclosing wall enclose a receiving cavity with an open mouth at one end, the receiving cavity is configured to hold the storage bag. The lid is detachably connected to the container body and is configured to seal the open mouth.
