Perforated Pull-Through Sleeve for Wet-Dry Food Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food packaging solutions require consumers to perform multiple steps to combine high moisture and low moisture ingredients, often resulting in the low moisture item becoming soggy due to premature mixing, which is undesirable for maintaining the crunchiness of dry ingredients like granola.
Innovation Solution
A food container design featuring a perforated sleeve that can be pulled through a narrow slot in the lid, breaking perforations and releasing dry ingredients into a wet ingredient compartment, simplifying the mixing process while keeping ingredients separate until consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate containers or complex opening mechanisms are used to keep wet and dry ingredients separate, then the dry ingredients maintain their crunchiness, but the device complexity increases and requires multiple steps to combine ingredients
Solution Approach 1:
The container is segmented into two functional zones: an inner collapsible pouch for dry ingredients and an outer container for wet ingredients. The pouch can be collapsed inward to minimize space while maintaining separation, and perforations are strategically placed to enable controlled mixing only when needed. This segmentation allows reliable maintenance of dry ingredient quality while using a relatively simple overall structure.
2Ease of manufacture
If ingredients are kept separate in simple packaging, then the packaging is easy to manufacture, but the consumer must perform multiple steps to open and combine ingredients
Solution Approach 1:
The invention merges the separation function and mixing function into a single integrated packaging system. The inner pouch with perforations serves both to keep ingredients separate during storage and to enable easy mixing when pulled. The tab mechanism combines the opening and mixing actions into one simple consumer operation, eliminating the need for separate opening and combining steps while maintaining simple manufacturing processes.
3Ease of operation
If the sleeve is pulled through the narrow slot to mix ingredients, then the mixing process is simplified, but the force required to pull the sleeve increases
Solution Approach 1:
The sleeve is designed to be dynamically responsive to the pulling force applied by the consumer. As the tab is pulled through the narrow slot, the sleeve gradually collapses and the perforations break, allowing ingredients to mix progressively. The narrow slot provides friction that controls the rate of mixing, transforming a potentially high-force instantaneous action into a lower-force progressive action that is easier for consumers to perform.

AI summary
A food package for wet and dry ingredients with a pull-through sleeve. A container is filled with a wet food product. A sleeve filled with a dry food product is enclosed within the container by having the bottom end of the sleeve affixed to the bottom of the container and the top end of the sleeve extending through a narrow slot in the lid of the container. The sleeve is formed with perforations along its length in a helix. When top end of the sleeve is pulled up through the narrow slot in the lid of the container, the sleeve is stretched and the perforations break following the helical pattern thereby releasing the dry food product from the sleeve into the wet food product in the container.
