Bottle and stand for removing contents from bottle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensers fail to efficiently extract all liquid from bulk containers, as some liquid gets stuck at the bottom due to a flat bottom surface and the need to invert the bottle, leading to messes during refilling.
Innovation Solution
A two-part liquid dispenser with an inner container designed to hold a bottle in an inverted position and an outer housing featuring an angled bottom surface that draws liquid towards the pump, allowing for complete extraction and minimizing mess during refilling by inverting the pump and outer housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the bottle is inverted on its cap to get liquid out, then more liquid can be extracted from the bulk container, but liquid still gets stuck at the top of the bottle and spills during refilling
Solution Approach 1:
The pump assembly is designed to be inverted during the refilling process. The pump housing includes a top surface that contacts the support surface when inverted, and the pump aperture faces downward to receive liquid from the inverted bottle. This inversion allows residual liquid to drain into the pump housing rather than spill outward, and the housing directs liquid flow to prevent mess during refilling operations.
2Ease of manufacture
If the dispenser has a flat bottom surface, then the structure is simple, but liquid gets stuck at the bottom and cannot be fully dispensed
Solution Approach 1:
The pump housing includes an angled bottom surface that slopes downward toward the pump aperture. This angled surface guides liquid flow toward the pump opening, ensuring that liquid accumulates at the lowest point where it can be effectively drawn into the pump. The curved or sloped geometry prevents liquid from stagnating in dead zones while maintaining manufacturing simplicity.
3Ease of manufacture
If the inner container opening is fixed size, then the manufacturing is simpler, but it cannot accommodate different sized bottles
Solution Approach 1:
The inner container opening is designed with flexible sidewalls that can expand and contract to accommodate bottles of different sizes. The flexible material allows the opening to dynamically adjust its dimensions to fit various bottle configurations while maintaining a simple single-piece manufacturing process. This elasticity provides adaptability without requiring complex adjustable mechanisms.
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 solution effectively reduces liquid residue at the bottom of the dispenser and prevents spills during refilling by ensuring all liquid is extracted and any residual liquid drips onto the outer housing, maintaining a clean environment.
Implementation Method 1
an angled bottom surface inside the inner container that draws the liquid towards the tube extending from the pump
Implementation Method 2
the pump is designed to draw liquid into the first aperture

AI summary
The present invention is a liquid dispenser, with an inner container, and an outer housing. The inner container is designed to hold a bottle in an inverted position so the liquid stuck at the bottom of the bottle may be emptied into the inner container. The inner container also includes an inner surface designed to draw liquid to the center of the inner container. This reduces the amount of liquid that gets stuck at the bottom of the inner container and allows a user to extract all of the liquid from the inner container. The outer housing is designed to cover the inner container hold a pump and cover the inner container. The lotion dispenser also includes suction cups to secure the inner container to a surface and be self-supporting.
