Pull Tab Catch Basin for Juice Collection in Beverage Closures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage container end closures with pull tabs face issues such as juice spillage, contamination, and user safety concerns when trying to squeeze fresh fruit juice into the container, as the juice often spills on the user or surrounding areas, and the container end closures can become dirty, leading to debris being ingested.
Innovation Solution
A novel metallic end closure with a pull tab system that includes a peripheral curl, chuck wall, countersink, inner panel, and a pull tab with a catch basin and drainage features to collect and direct juice efficiently into the container, reducing spillage and contamination, while ensuring user safety by minimizing contact with the pour opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pour opening is used, then juice can be poured into the container, but juice spills on the user and surrounding areas
Solution Approach 1:
The pull tab acts as an intermediary device between the user and the container opening. It provides a controlled interface for juice transfer, capturing spilled juice in its catch basin and directing it through drainage holes into the container, thereby mediating the harmful spillage effect
Solution Approach 2:
The pull tab extracts the juice spillage problem from the main pouring function by providing a separate catch basin specifically designed to capture and contain spilled juice, isolating the harmful spillage effect from the user and surroundings
2Productivity
If juice is squeezed onto the end closure, then juice enters the container, but the end closure becomes dirty and debris is ingested
Solution Approach 1:
The pull tab serves as a clean intermediary surface for juice collection. Its smooth, non-porous surface prevents dirt and debris from the end closure from mixing with the juice, while drainage holes provide a controlled path for juice to enter the container without contact with contaminated surfaces
Solution Approach 2:
The pull tab segments the juice collection function from the end closure surface by providing a separate, dedicated area (the tab surface) for juice placement and collection, preventing contamination from the surrounding end closure areas
3Object-affected harmful factors
If the pour opening is made smaller to reduce spillage, then juice spillage decreases, but users cannot push fruit into the opening
Solution Approach 1:
The solution moves the fruit insertion action to another dimension by providing a large flat surface (the pull tab) where fruit can be placed and pressed, rather than requiring direct insertion through the small opening. The tab acts as an extended working surface that bypasses the size limitation of the opening
4Productivity
If a larger pull tab is used to facilitate juice collection, then juice collection efficiency improves, but the tab may interfere with the pour opening
Solution Approach 1:
The pull tab is segmented into functional zones: a large catch basin area for juice collection, drainage holes for controlled juice release, and a nose portion that fits through the opening. This segmentation allows the tab to be large for efficient collection while maintaining compatibility with the opening dimensions
