Package for laundry scent additive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging designs for particulate laundry scent additives are prone to dosing cup separation during handling, leading to incomplete products, potential spills when consumers test the scent, and inconvenience in dispensing with two hands.
Innovation Solution
A package design featuring a container, closure, and dosing cup with a shrink sleeve wrapping around the container and dosing cup, providing a secure engagement mechanism and allowing scent sampling without opening the package, while enabling one-handed use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dosing cup is peripherally snapped to the closure, then the dosing cup is positioned conveniently for use, but the dosing cup may become separated from the closure during shipping or handling
Solution Approach 1:
The shrink sleeve merges the container, closure, and dosing cup into a single integrated unit. By wrapping the shrink sleeve around all three components and shrinking it to conform tightly, the invention combines separate elements that are prone to separation into one cohesive package, eliminating the reliability issue while preserving operational convenience.
Solution Approach 2:
The shrink sleeve is a flexible thin film that wraps around the container, closure, and dosing cup. When heated, it shrinks to form a tight conformal fit that secures all components together. This flexible film approach provides strong attachment without interfering with the dosing cup's peripheral engagement with the closure.
2Ease of operation
If the consumer opens the closure to smell the product, then the consumer can verify the scent, but the product may be spilled or exposed to the environment
Solution Approach 1:
The invention extracts the scent sampling function from the closure-opening action. The vent opening is specifically designed to extract only the scent capability while leaving the closure intact, allowing consumers to smell the product without opening the closure and risking spillage.
Solution Approach 2:
The vent opening acts as a porous pathway through the otherwise sealed package. It allows selective passage of scent molecules while maintaining the integrity of the closure and preventing product spillage. The vent opening provides controlled access that satisfies the sampling need without compromising product containment.
3Reliability
If the consumer handles three separate elements (container, closure, dosing cup), then the product can be securely packaged, but dispensing becomes inconvenient with only two hands
Solution Approach 1:
The shrink sleeve merges three separate handleable elements into one integrated unit that can be grasped and transported as a single object. This combination maintains the security benefits of separate components during transport while eliminating the complexity of handling multiple pieces during dispensing operations.
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 enhances product integrity during handling, allows consumers to sample the scent without spilling, and simplifies dispensing with only two hands, addressing the issues of separation, spillage, and convenience.
Implementation Method 1
a shrink sleeve wrapping around the container and the closure and at least a portion of the tapered portion of the dosing cup wall thereby providing a redundant mechanism of engagement between the dosing cup and the container
