Tethered Beverage Closure With Dual Tamper-Evident Opening Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tethered closures for beverage containers do not reliably indicate if the drink has been previously opened, and there is a risk of parts being lost during use, leading to environmental concerns.
Innovation Solution
A tethered closure device with rotatable cap and frame components, featuring two tamper evident elements to visually or haptically indicate opening status, and a seal opening mechanism to ensure parts remain connected, allowing easy resealing and preventing loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If tethered closures are used to prevent part loss, then environmental friendliness is improved, but the ability to reliably indicate beverage opening status deteriorates
Solution Approach 1:
The closure system is divided into separate functional components: a tethered cap assembly that prevents loss, and distinct tamper-evident elements (seal ring, bridge elements) that provide opening status indication. This segmentation allows each component to specialize in its primary function without compromising the other.
Solution Approach 2:
Tamper-evident elements serve as intermediary indicators between the closure system and the user. These elements (seal ring, bridge elements) provide visual and haptic information about opening status without interfering with the tethered closure's primary function of preventing part loss.
2Ease of operation
If traditional separate lids are used, then ease of operation is improved, but the risk of part loss and improper disposal increases
Solution Approach 1:
The cap and closure functions are merged into a single tethered assembly that remains connected to the beverage container. The cap element can still be removed and replaced for easy operation, but the tether connection prevents complete separation and loss, combining the benefits of both separate lids and secured closures.
Solution Approach 2:
The closure system transitions from a static connected state to a dynamic removable state during normal use, then returns to a secured state via the tether. This dynamic behavior allows easy operation when needed while maintaining security during storage and transport.
3Loss of information
If tamper evident elements are added to indicate opening status, then information reliability is improved, but device complexity increases
Solution Approach 1:
The tamper-evident elements are integrated into the existing cap and frame structure, serving multiple functions: the seal ring provides both sealing and tamper indication, while the bridge elements serve as both structural connectors and opening status indicators. This multi-functionality reduces the need for separate dedicated indicator components.
