Container Having A Resealable Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container caps lack a reliable mechanism for ensuring tamper evidence and easy repositioning between sealed and open states, which can lead to unintended leakage or contamination.
Innovation Solution
A resealable cap design featuring a beauty cap and a lug cap with a tamper insert and dimples, allowing for secure sealing and easy opening, along with a tamper identifier for indicating the cap's position, ensuring the cap remains sealed when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional cap design is used, then the structure is simple, but it lacks tamper evidence and reliable sealing mechanism
Solution Approach 1:
The cap is divided into multiple functional segments: a beauty cap for user interaction, a lug cap for coupling, and a tamper insert for security. Each segment performs a specific function, allowing the overall system to achieve high reliability through modular design while keeping individual components relatively simple.
Solution Approach 2:
The tamper insert is nested within the lug cap structure, with the tamper insert positioned inside the lug cap and engaging with protrusions on the container top. This nested arrangement allows the tamper evidence mechanism to be integrated into the existing cap structure without adding significant external complexity.
2Reliability
If a secure sealing mechanism is implemented, then product integrity is improved, but ease of repositioning between sealed and open states deteriorates
Solution Approach 1:
The cap assembly incorporates dynamic elements including a flexible seal that can deform during opening/closing operations, and a rotatable mechanism that allows transition between sealed and open states. The seal flexes to engage with the container opening during sealing, and the cap can be rotated to different positions, providing ease of operation while maintaining secure sealing when closed.
3Reliability
If a tamper insert with protrusions is used, then tamper evidence is improved, but the mechanism for easy opening deteriorates
Solution Approach 1:
The tamper insert acts as an intermediary element between the lug cap and the container top. It features protrusions that engage with corresponding features on the container top to provide tamper evidence, while simultaneously allowing the lug cap to rotate or move relative to the container. This intermediary mechanism enables both tamper evidence functionality and ease of opening through rotational movement.

AI summary
A resealable cap includes a container top comprising a plurality of protrusions extending inward assembly includes a beauty cap positioned on a top of the cap assembly that has an interface extending along a midpoint of the beauty cap and also includes a lug cap coupled to the beauty cap and including a lug cap interface positioned about a perimeter of the lug cap and configured to receive the plurality of protrusions. A tamper insert is coupled to the beauty cap at an underside of the beauty cap and positioned within the interface.
