Deformable Film Cap for Hermetic Substance Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for fluid-tight mixing of substances with a container face challenges in ensuring complete prevention of external degrading agents, such as humidity, from penetrating into the sealed chamber, which can compromise the sealing integrity.
Innovation Solution
A device comprising a concave cap with a deformable and conical portion, a thermowelded film chamber, and a breaking element with film-breaking spokes and teeth, ensures fluid-tight sealing and easy mixing by applying pressure to break the film and release the substance into the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable closing wall is used to seal the chamber, then the device is easy to operate, but the sealing against external degrading agents may be compromised
Solution Approach 1:
The chamber is hermetically sealed with a deformable film before use, and the breaking element is pre-positioned inside the chamber. This preliminary sealing action ensures complete protection against humidity and degrading agents, while the pre-positioned breaking element ready for activation maintains ease of operation.
Solution Approach 2:
The breaking element is extracted as a separate, removable component that can be inserted into the chamber through the opening. This allows the chamber to be hermetically sealed with the film while still accommodating the breaking element, resolving the contradiction between sealing integrity and ease of operation.
2Reliability
If plastic materials are used to seal the chamber, then fluid-tight sealing is achieved, but penetration of degrading agents may still occur in unfavorable conditions
Solution Approach 1:
A deformable film made of flexible material is used to hermetically seal the chamber. This film can be deformed by the breaking element to open the seal, providing both complete sealing integrity and controlled access. The flexible nature of the film allows it to maintain hermetic sealing while being penetrable when needed.
3Object-affected harmful factors
If a hermetically sealed chamber is used, then protection against contamination is improved, but the complexity of the device increases
Solution Approach 1:
The device is segmented into distinct functional components: the hermetically sealed chamber, the breaking element, and the dispensing mechanism. This segmentation allows each component to be optimized independently while maintaining overall simplicity. The chamber provides complete protection, while the breaking element adds minimal complexity for access.
Solution Approach 2:
The breaking element is designed to be inserted and activated by the user without requiring complex tools or procedures. The deformable film automatically seals when the breaking element is removed, providing self-service sealing functionality that minimizes device complexity while maintaining protection against contamination.

AI summary
Device for the fluid-tight conservation of a first substance to be mixed with a second substance, which is contained in a container (1) comprising an outer concave cap (2) comprising an edge portion (21) adapted to seal the mouth (11) of the container, and having, on the upper side, a deformable portion (22) and, on the lower side, a conical portion (23), which can be inserted, by applying pressure, into said mouth of the container, inside which a chamber (C) to contain said first substance is defined. The device comprises, furthermore, a breaking element (3) comprising a stem (31), which, at its upper end, substantially strikes from the inside the deformable portion of the cap and is able to move downwards after a pressure has been applied onto said deformable portion of the cap, and holding means to hold said element inside the cap after said pressure has been applied onto the cap itself, said means being adapted to prevent the element itself from keeping moving downwards outside the cap.
