Spout Dispenser With Integrated Seal Ring For Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional threaded caps face challenges in balancing impact tolerance and leak performance, as increasing dosage capacity above the bottle neck can compromise impact tolerance, leading to breakage, and separate seal installation can disrupt proper sealing and cause leaks.
Innovation Solution
A spout dispenser member with a central duct, an outer sidewall, and a seal ring, where the central duct and outer sidewall are made of a first material and the seal ring of a second, softer material, integrated as a single element, ensuring proper sealing and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the cap's dosage capacity is increased above the end of the bottle neck, then the cap can hold more fluid dosage, but the cap's impact tolerance is compromised and it breaks more easily
Solution Approach 1:
The cap is divided into multiple portions with different functions: an upper portion for holding dosage and a lower portion for impact resistance. The lower end of the upper portion has a reduced transverse dimension, creating a tapered transition zone that allows the cap to withstand impact forces while maintaining adequate dosage capacity in the upper section.
2Reliability
If a separate seal is installed between the spout and container opening, then the seal can provide sealing function, but the seal placement may be disrupted and leaking risk increases
Solution Approach 1:
The seal is integrated directly into the spout structure, forming a single-piece component. The seal extends from the container opening upward along the spout's exterior surface, eliminating the need for separate seal installation and ensuring proper sealing position is maintained during assembly.
3Ease of manufacture
If the spout and seal are made as separate components, then manufacturing flexibility is improved, but assembly complexity increases and proper seal placement is harder to ensure
Solution Approach 1:
The spout and seal are combined into a single integral component manufactured as one piece. This eliminates separate assembly steps, ensures the seal is always in the correct position, and simplifies both manufacturing and assembly processes while maintaining the functional benefits of having a dedicated seal structure.
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 integrated design enhances the cap's ability to withstand impact forces while maintaining a secure seal, preventing leaks and facilitating easy assembly by ensuring proper placement of the seal ring.
Implementation Method 1
a seal ring disposed on the flange of the outer sidewall, wherein the central duct and the outer sidewall include a first material having a first durometer and the seal ring includes a second material having a second durometer less than the first durometer
Implementation Method 2
the associated container assembly includes a container having a neck having a rim defining an opening into the container and a cap removably coupled to the neck. The spout includes an outer sidewall extending around the central duct, wherein the outer sidewall is configured to engage an interior surface of the container and having an upper end and a flange projecting in a radial direction from the upper end.
