Detachable Stripping Web for Lid Edge Scraping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for dry products like baby milk powder face challenges in precise dosing due to the high manufacturing costs of integrated measuring spoons and the complexity of producing non-circular lids, which require specialized tools and increase production costs.
Innovation Solution
A dosing spoon with a detachable stripping web that can be easily attached to the edge of the removal opening, allowing for flexible production and logistics, where the stripping function is added as a separate part that can be connected to the spoon or lid, enabling precise dosing without altering the manufacturing process for all lid types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an integrated measuring spoon with scraper is manufactured, then dosing precision is improved, but manufacturing cost increases significantly
Solution Approach 1:
The measuring spoon is divided into two separate components: a standard spoon and a detachable stripping web. The stripping web can be attached to the spoon handle or lid edge, providing the scraping function without integrating it into the spoon body. This segmentation allows each component to be manufactured separately using simple, cost-effective processes while maintaining precise dosing capability when assembled.
2Ease of operation
If a non-circular opening (D-shape) is created in the lid for integrated scraper function, then scraping capability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of modifying the lid opening shape to accommodate an integrated scraper, the invention inverts the approach by providing a separate detachable stripping web that can be attached to either the spoon or lid. This allows the lid to maintain a simple circular opening that is easy to manufacture, while the scraping function is provided by the separately manufactured stripping web component.
Solution Approach 2:
The scraping function is extracted from the lid structure and embodied in a separate detachable stripping web component. This allows the lid to be manufactured with a simple circular opening using standard tools, while the scraping capability is provided by the separate stripping web that can be attached as needed.
3Ease of operation
If D-shape peel-off lids are manufactured with integrated scraper bar, then scraping function is improved, but production time and reorientation requirements increase
Solution Approach 1:
The scraping function is segmented into a separate detachable stripping web component rather than being integrated into the lid. This allows lids to be manufactured with simple circular openings using standard circular tools, eliminating the need for complex non-circular tooling and reducing production time. The stripping web is attached separately after lid production.

AI summary
With a packaging comprising a dosing spoon (3) for removing a filling material from the packaging, a container of the packaging is closed with a tear-off lid, which has a tear-off lid ring (7) and a tear-off film. A scraper strip (6) is provided, which can be fastened to the edge (18) of the tear-off lid ring (7) after the tear-off film is removed. The scraper strip (6) can be present in particular in combination with the dosing spoon (3) in the packaging so that the scraper strip can be detached from dosing spoon after the packaging is opened and fastened to the edge of the tear-off lid ring.
