Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing systems for flowable products, such as powders, often result in surface contamination and complex cleaning processes due to direct contact with the user during recharging and discharging, and are costly and difficult to manufacture.
Innovation Solution
A packaging system with a sealed body and internal opening element that can be activated by external force to create an opening within the packaging, allowing for convenient and clean recharging while maintaining the product sealed, using a fastening part integrated into the sealing line and a flexible or stiff opening element to facilitate easy opening and large flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a slidable band is used to close the packaging bottom and is removed by sliding in a slot, then the powder can flow out freely, but the slot becomes soiled and requires thorough cleaning
Solution Approach 1:
The opening element is extracted from the traditional bottom closure design and repositioned to the top sealing line. The fastening part is sealed in the sealing line while the opening part can be pulled through the sealing line to create an opening, separating the closure function from the powder contact area.
Solution Approach 2:
The opening element acts as an intermediary mechanism between the sealed packaging and the powder flow. It provides a controlled opening path that prevents direct contact between powder and the dosing system surfaces, while still allowing free powder flow through the created opening.
2Ease of operation
If the opening element is fastened to the body at the activation section, then the opening can be created from inside the packaging, but the structure becomes more complex
Solution Approach 1:
The opening element combines multiple functions into a single component: the fastening part integrates with the sealing line to provide initial closure, while the opening part integrates the activation mechanism and the actual opening creation function. This merging reduces the number of separate components needed.
Solution Approach 2:
The opening element serves multiple purposes: it acts as a closure mechanism when fastened to the body, provides an activation interface for the user, and creates the opening path for powder flow. This multi-functionality simplifies the overall packaging design while maintaining ease of operation.
3Ease of manufacture
If the body is made flexible to allow opening element displacement, then the opening can be created easily, but the manufacturing precision becomes more difficult to control
Solution Approach 1:
The packaging body exhibits different mechanical properties in different regions: the main body is flexible to allow opening element displacement and deformation during opening, while the sealing line area maintains higher structural integrity to ensure proper sealing. This local differentiation of material properties or structural characteristics resolves the contradiction between flexibility and precision.

AI summary
The present invention is directed to a packaging (1) comprising: - a body (2) defining an interior volume (6) for carrying a flowable product, and - an opening element (4) comprising an opening part (4.0) which is arranged inside the interior volume (6). The body (2) is configured such that, when a predetermined external force (F) is exerted on an activation section (8) of the body (2), the activation section (8) is displaced relative to the interior volume (6) so as to activate the opening element (4) until the opening part (4.0) creates an opening extending in an openable section (12) of the body (2) and allowing the flowable product to flow out of the interior volume (6).
