Solution Overview
Problem
Existing dosing systems for flowable products face issues with convenience, reliability, and cleanliness during packaging replacement, leading to soiled surfaces and high manufacturing costs.
Innovation Solution
A dosing system with a packaging that includes an opening element activated by an external force to create an opening for flowable product discharge, ensuring cleanliness and ease of use, featuring a flexible body and stiff opening element for controlled opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slidable band is used to close the packaging bottom, then the powder can be dispensed by gravity, but the slot where the band slides becomes soiled requiring thorough cleaning
Solution Approach 1:
The closing function is extracted from a slidable band mechanism and transferred to an adhesive closure system. The adhesive strip is applied directly to the packaging surface and removed cleanly without requiring sliding through a slot, thereby eliminating the soiling problem while maintaining the dispensing function.
Solution Approach 2:
The adhesive closure system uses a disposable adhesive strip that is applied and then removed with the packaging or in a controlled manner, avoiding the need for repeated cleaning of a slot. The closure mechanism is simple and does not create persistent contamination issues.
2Ease of operation
If a press board with cutter is used to open the container, then the container can be opened, but the manufacturing and operating cost increases
Solution Approach 1:
The cutting function is extracted from a complex press board mechanism and simplified to an adhesive-based closure system. The adhesive strip can be easily removed by peeling, eliminating the need for mechanical cutting components and reducing manufacturing complexity and cost.
Solution Approach 2:
The mechanical cutting system (press board with cutter) is replaced with a chemical/adhesive-based closure system. The adhesive bond is broken by peeling rather than mechanical cutting, substituting a simpler mechanical action that reduces manufacturing requirements.
3Ease of operation
If the packaging is opened from the outside, then the opening is created, but the flowable product may become contaminated
Solution Approach 1:
Instead of opening the packaging from the outside, the closure system is designed to be opened from the inside. The adhesive strip is applied to the inner surface and removed from the inside, allowing the opening action to occur within the sealed environment and preventing external contamination.
Solution Approach 2:
The adhesive strip acts as an intermediary closure mechanism that can be removed from the inside without direct contact between the user's hands and the product. The adhesive bond breaks in a controlled manner that maintains product integrity and prevents contamination.

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 10 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).
