Fluid Dispenser Head with Flexible Deformable Zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid dispensers with axially mounted dispensing heads require off-center pressing, leading to aesthetic issues, inefficient force distribution, and potential fluid loss due to tilting and spillage, especially when used with high viscosity products like creams and gels.
Innovation Solution
The dispensing head incorporates a peripheral skirt with a flexible deformable zone connecting the skirt, cup, and orifice, allowing for balanced pressing force distribution and a sealed junction to prevent fluid loss, maintaining the aesthetic appearance of a classic pot-style dispenser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the dispensing head is mounted axially on the outlet of the dispensing member with the dispensing orifice located in the axis of the dispensing member, then the dispenser has a simple structure, but it requires strong pressing force that deforms the outlet of the dispensing member and causes the dispensing head to tilt
Solution Approach 1:
The patent introduces a deformable membrane element that allows the dispensing head to dynamically adapt to pressing forces. The membrane deforms under eccentric pressing, redistributing the force through the pumping element without causing rigid tilting or deformation of the dispensing member outlet, thus maintaining ease of operation while preserving the simple axial mounting structure.
2Device complexity
If the dispensing orifice is located at the axis of the dispensing member, then the structure is simple, but pressing off-center causes the dispensing head to lean or tilt and creates aesthetic issues
Solution Approach 1:
The patent employs a flexible membrane as the dispensing head structure. This thin film element can deform under off-center pressing forces, absorbing the eccentric load and preventing the rigid tilting that would compromise aesthetic appearance. The membrane's flexibility allows it to return to its original shape after pressing, maintaining the desired appearance while accommodating simple axial mounting.
3Device complexity
If the dispensing head is pressed off-center to actuate it, then the structure remains simple, but part of the dispensed fluid product can spill over the edge and pass underneath, causing hygiene issues
Solution Approach 1:
The deformable membrane dynamically responds to pressing forces by deforming in the direction of the applied force, which controls the dispensing orifice opening. This dynamic deformation ensures that fluid is dispensed in a controlled manner that remains contained within the recovery cup, preventing spillage underneath the dispensing head even when pressed off-center, thus maintaining hygiene without requiring complex containment structures.
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
This design ensures optimal actuation without tilting, reduces fluid loss, and maintains hygiene by distributing the pressing force around the periphery, even when pressed eccentrically, while maintaining the appearance of a classic pot-style dispenser.
Implementation Method 1
the skirt is connected to the cup, to the bearing surface and to the orifice by a flexible deformable zone... the deformable zone makes it possible to balance the pressing force, when the latter is exerted off-center on the dispensing head
Implementation Method 2
the peripheral skirt makes it possible to produce a junction, advantageously sealed, with the rest of the dispenser... the deformable flexible zone not only makes it possible to connect the skirt to the rest of the head
