Flexible Dispenser Insert for Precise Essential Oil Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current essential oil dispensing systems are inefficient, leading to waste as they fail to dispense oil precisely and effectively seal the opening when the cap is closed, and do not facilitate efficient transfer of oil into sample bottles.
Innovation Solution
A dispensing tip insert made from corrosive-resistant plastic with a flexible, oil-resistant rubber O-ring that fits securely into the bottle neck, allowing precise oil dispensing by creating a seal and enabling efficient transfer into sample bottles through a vacuum effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic orifice reducer is used for dispensing essential oil, then the dispensing structure is simple and easy to manufacture, but the oil dispensing precision is poor and waste occurs
Solution Approach 1:
The patent employs a flexible rubber insert with a lip that can deform to open or close the orifice. This flexible membrane structure allows precise control of oil flow by deforming under finger pressure to open the orifice for dispensing, then returning to closed position to seal the opening, eliminating waste while maintaining simple manufacturing.
Solution Approach 2:
The orifice reducer transitions from a static plastic structure to a dynamic flexible rubber insert that can change shape. The lip of the rubber insert dynamically opens and closes the orifice in response to user interaction, enabling precise dispensing control and sealing action that prevents oil waste.
2Reliability
If a plastic orifice reducer with oil spill compartment is used, then the structure provides oil containment, but the sealing effectiveness is poor and oil spills into the closed cap
Solution Approach 1:
The flexible rubber insert with its deformable lip creates an effective seal at the orifice opening. When the lip returns to its relaxed closed position after dispensing, it tightly seals the orifice, preventing oil from spilling into the closed cap while maintaining the oil spill compartment's containment function.
Solution Approach 2:
The rubber insert automatically seals the orifice after dispensing without requiring additional sealing mechanisms. The elastic memory of the rubber material causes the lip to return to its closed position on its own, creating a self-sealing system that prevents oil spillage into the cap.
3Productivity
If current orifice reducers are used for transferring oil to sample bottles, then the transfer process is simple, but the transfer efficiency is low and waste occurs
Solution Approach 1:
The patent replaces inefficient manual pouring or dripping methods with a controlled mechanical deformation system. By deforming the rubber insert, users can precisely control oil flow during transfer to sample bottles, eliminating waste while maintaining simple operation and improving transfer efficiency.
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 eliminates oil waste by ensuring precise dispensing and effective sealing, allowing for efficient transfer of essential oils from main bottles to sample bottles, reducing spillage and promoting cleaner, faster measurement.
Implementation Method 1
The orifice maintains a closed configuration in an undeformed state and an open configuration for passage of a liquid in a deformed state subject to application of an external force on the upper section of the dispenser insert
Implementation Method 2
allowing precise oil dispensing by creating a seal and enabling efficient transfer into sample bottles through a vacuum effect

AI summary
An apparatus includes a pliable material to form a dispenser insert. The dispenser insert includes a lower section and an upper section. The lower section is configured for insertion into and stable engagement with the mouth and interior of a dispensing container. The upper section is configured to extend outward and away from the mouth of the dispensing container. The upper section defines an orifice at a distal end of the upper section. The orifice maintains a closed configuration in an undeformed state and an open configuration for passage of a liquid in a deformed state subject to application of an external force on the upper section of the dispenser insert.
