Elastic Strip Food Package Preventing Granule Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food packages containing granules, such as sugar cubes, often experience leakage during transport and storage due to the separation of granules, which is exacerbated by the lack of adhesive use to prevent contamination and environmental concerns related to plastic bags, leading to practical and cleanliness issues.
Innovation Solution
A packaging box design featuring a body with elastic rotatable strips that touch the cover wall, providing a spring-like mechanism to minimize leakage without using glue, and made from paperboard with asymmetrical layers for elasticity and water-impermeability, allowing for high-density packaging without leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If no or hardly any glue is used in packaging boxes, then contamination of food product is prevented and environmental concerns are addressed, but granules may get spilled from the package
Solution Approach 1:
A flexible cover acts as an intermediary element between the food product and the external environment. The cover is held in place by elastic strips that create friction contact with the box walls, providing a mechanical barrier that prevents granule spillage without requiring adhesive bonding to the food product itself.
Solution Approach 2:
The packaging box employs a flexible cover made of thin material that can conform to the box interior. This flexible shell is secured through elastic strips that create friction contact with the box walls, providing a spill-prevention barrier while maintaining the no-glue principle for food safety and environmental reasons.
2Loss of substance
If plastic bags are used around food products, then granule spillage is prevented, but environmental concerns are raised and packing density is reduced
Solution Approach 1:
The flexible cover serves as an intermediary barrier between the food product and the external environment, preventing granule spillage. This cover is secured using elastic strips that create friction contact with the box walls, eliminating the need for plastic bags while maintaining packing density and addressing environmental concerns.
Solution Approach 2:
The packaging box uses a flexible cover made of thin material that can conform to the box interior. This flexible shell is secured through elastic strips creating friction contact with the box walls, providing spill prevention without requiring plastic bags, thus addressing both environmental and density concerns.
3Productivity
If packaging boxes are designed for high density and good stacking, then space utilization is improved, but granules may get spilled from the package
Solution Approach 1:
The flexible cover acts as an intermediary barrier that prevents granule spillage while allowing the packaging box to maintain its high-density, stackable design. The cover is secured by elastic strips that create friction contact with the box walls, ensuring stability during stacking and transport without compromising packing density.
Solution Approach 2:
The packaging box employs a flexible cover made of thin material that can conform to the box interior. This flexible shell is secured through elastic strips that create friction contact with the box walls, providing spill prevention while maintaining the high-density packaging structure suitable for efficient stacking and storage.

AI summary
The invention relates to a food package comprising a plurality of food products comprising granules, such as sugar cubes. The food package further comprises a packaging box arranged around the food products and comprising a body (10) and a cover (60). The body (10) is provided with a bottom wall (11) and first and second mutually opposed side walls (12, 16), therewith defining an inner space in the body (10) for the food products. The inner space of the body (10) is exposed at a top side for provision and removal of food products. The cover (60) has a cover wall (61) which at least covers said exposed inner space of the body (10). The body (10) is provided with at least one strip (21, 22) extending above said inner space. The strip is interconnected to a corresponding one of the first and second side walls (16, 12) along an edge (23, 24) of the body, touches the cover wall (61) - in at least a portion of the strip and at least substantially - and is configured to be elastically rotatable along the said edge (23, 24) of the body (10).
