Integrated Butter Spreading Package Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing individual portion packages for spreading butter or similar foodstuffs on bread often require a separate knife, leading to contamination and inconvenience, as they necessitate the use of both hands and can be difficult to manufacture efficiently.
Innovation Solution
An integrated container with a spreading device that includes a first wall and a second wall connected by a weak adhesive, where the second wall forms a gripping device that covers the spreading device, allowing easy dispensing and protection from contamination, with the option of a kerf line for manual separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate knife is used to spread butter from the container, then the spreading function is achieved, but contamination occurs and both hands are required for operation
Solution Approach 1:
The spreading device is integrated directly into the container structure, merging the container and spreading tool into a single unit. This eliminates the need for a separate knife, prevents contamination, and allows one-handed operation by incorporating the spreading blade as an extension of the container wall.
2Ease of operation
If the spreading device is integrated with the container, then contamination is prevented and one-handed operation is enabled, but manufacturing complexity increases
Solution Approach 1:
The container is divided into functional zones: a first wall extension forming the spreading blade and a second wall extension forming the gripping device. These segments are connected by weak adhesive that allows easy separation after use, simplifying manufacturing while maintaining the integrated structure during use.
Solution Approach 2:
The spreading device and gripping device are pre-formed as extensions of the container walls during the molding process, eliminating the need for separate manufacturing steps and assembly operations, thereby reducing manufacturing complexity.
3Object-affected harmful factors
If the gripping device covers the spreading device, then protection from contamination is achieved, but the structure becomes more complex
Solution Approach 1:
The gripping device is formed as an extension of the container's second wall, merging the protective cover and gripping handle into a single continuous structure. This eliminates the need for separate protective covers and simplifies the overall structure while maintaining contamination protection.

AI summary
The invention relates to an individual portion package containing butter, soft cheese or other foodstuff intended for spreading on a piece of bread or the like. The package includes a closed container (1) and spreading device (2). The spreading device (2) is integrated with the container (1) and projecting out from the container (1). The container is formed by a first wall (6) and a second wall (3) connected to each other. The first wall (6) has a first extension forming the spreading device (2). The second wall (3) has a gripping device (4) at the end of the container (1) adjacent the spreading device (2). The gripping device (4) is arranged for opening the container (1) at this end for providing a dispensing opening (5) allowing the content of the container to be squeezed out onto a supply side (2a) of the spreading device (2). The supply side (2a) is on the same side of the first wall (6) as the container (1). The gripping device (4) forms a second extension of the container(1) in the direction of the spreading device (2). The second extension completely covers the supply side (2a) of the spreading device (2).
