Laundry Container Window Layout for Visible Liquid Level
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face difficulties in completely dispensing liquid laundry products from containers, especially with surface tension issues in pouring containers, pump dispenser inefficiencies, and difficulty gauging remaining product in tap dispensers, leading to incomplete use and uncertain repurchase timing.
Innovation Solution
A container design featuring a translucent peripheral wall with an opaque overlay, including a primary label face oriented upright when the container is closed and a secondary label face with text that becomes upright when inverted, along with a window to visually indicate the liquid level, facilitating complete dispensing and timely repurchasing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pump dispenser is used to dispense liquid laundry product, then dispensing convenience is improved, but complete extraction of liquid from the container becomes difficult
Solution Approach 1:
The pump inlet is positioned in a sump area at the bottom of the container before dispensing begins. This preliminary positioning ensures that the pump can access and extract all liquid product, including residual amounts, by drawing from the lowest point in the container where liquid naturally accumulates.
2Loss of substance
If a tap dispenser is used to dispense liquid laundry product, then complete dispensing is improved, but ability to gauge remaining product quantity deteriorates
Solution Approach 1:
The container includes a translucent peripheral wall section that allows consumers to visually observe the liquid laundry product and gauge the remaining quantity. This transparent section provides real-time information about product levels without requiring the consumer to empty or manipulate the container, thus maintaining complete dispensing capability while adding quantity indication functionality.
3Reliability
If the container interior surface retains liquid via surface tension, then product protection is improved, but complete dispensing deteriorates
Solution Approach 1:
The pump inlet is specifically positioned in a sump area, extracting the liquid from the lowest point of the container where surface tension would otherwise cause retention. This extraction positioning overrides the surface tension effect by providing a dedicated collection and dispensing point that captures all remaining liquid product.
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
Ensures complete use of liquid laundry products by allowing easy observation of the remaining liquid through the window, enabling consumers to gauge when to restock and preventing waste, while maintaining product quality by minimizing light exposure.
Implementation Method 1
a translucent peripheral wall extending from said closed end periphery about a longitudinal axis of said container to an open end
Implementation Method 2
a substantially opaque over layer

AI summary
A laundry product that is a container and a liquid laundry composition contained in the container. The primary label face has text that is substantially upright when the container is resting on the closed end of the container. The secondary label face has text that is substantially up-side-down when the container is resting on the closed end of the container. The secondary label face has a window through which the liquid laundry composition within the container can be observed from outside the container.
