Closure Cap Tilt Mechanism for Sealed Container Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure caps for containers fail to ensure the contents remain sealed until first use and then easily accessible for consumption or use.
Innovation Solution
A closure cap design featuring a rigid element that tilts about a pivot and is connected to a flexible member, allowing pressure to open a sealed space by cutting a seal with an opening member, ensuring easy access to the contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closure cap is designed to keep contents sealed until first use, then sealing reliability is improved, but ease of opening deteriorates
Solution Approach 1:
The seal is pre-positioned between the rigid element and the base, and the opening member is pre-configured to cut the seal when the rigid element tilts. This preliminary arrangement ensures that upon first use, the seal is automatically broken without requiring complex opening actions, thus maintaining both sealing reliability and ease of opening.
Solution Approach 2:
The rigid element is designed to tilt dynamically when pressure is applied, transforming from a sealed state to an opened state. This dynamic mechanism allows the closure cap to maintain reliability during storage (sealed state) and provide ease of operation during use (opening action through tilting).
2Ease of operation
If a rigid element is made tiltable to open the seal, then ease of operation is improved, but device complexity deteriorates
Solution Approach 1:
The closure cap is segmented into distinct functional components: a rigid element for tilting, a flexible member for pressure application, an opening member for seal cutting, and a seal. This segmentation allows each component to perform its specific function simply, reducing overall mechanism complexity while maintaining ease of operation.
Solution Approach 2:
The mechanism is designed to be self-actuating through pressure application. When pressure is exerted on the rigid element, it automatically tilts and triggers the opening member to cut the seal without requiring additional actuators or complex control systems, thus reducing device complexity.
3Ease of operation
If pressure is applied to tilt the rigid element, then ease of operation is improved, but force required increases
Solution Approach 1:
The flexible member is designed with a curved or conical shape that concentrates the applied pressure onto a small area of the rigid element. This curvature amplifies the mechanical advantage, allowing a relatively small applied force to generate sufficient tilting moment to open the seal.
Solution Approach 2:
The opening member is integrated with the rigid element, so that the tilting motion of the rigid element directly drives the seal-cutting action. This merging eliminates the need for separate actuating mechanisms, reducing the force required while maintaining ease of operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for simple and reliable opening of the seal with minimal pressure, ensuring the contents are kept sealed until needed and then easily accessible for use or consumption.
Implementation Method 1
a flexible member (7), which is caused to flip over and rapidly makes a tilting movement when a mostly manual pressure is exerted on the rigid element (5)
Implementation Method 2
the opening member (9), which moves in a wide arch, improves the reliability with which the seal (10) can be cut

AI summary
An assembly (1) of a container (2) with an opening (4) and a closure cap (3) by means of which the opening can be closed, wherein said closure cap comprises: • - a rigid element (5) at the upper surface of the cap, which, on one side, can be tilted about a pivot (6) which is located in the upper surface or which extends parallel to said upper surface, and said rigid element is connected, on the other side, with a flexible member (7) which causes the rigid element to tilt when pressure is exerted thereon, and • - an initially closed space (8), located below the upper surface, which is bounded at the end faces by at least the ti liable, rigid element to which an opening member (9) projecting into said space is secured, and by a seal (10) which, when the rigid element is tilted, is cut and opened by the opening member.
