Dispensing Bottle Collar with Gadroons for Pump Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dispensing bottle technologies face instability issues during pump positioning due to the dip tube's elastic deformation, leading to potential tilting and leakage, especially in short and wide bottles, as the positioning and fixing stages are distinct and lack sufficient stability before deformation.
Innovation Solution
A dispensing bottle design that incorporates a collar with an annular outer skirt and gadroons to stabilize the pump positioning before deformation, ensuring tight fixing by folding claws under the collar, which are maintained in a folded position using a sliding ring, providing enhanced mechanical reliability and aesthetic cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collar is used to secure the pump to the neck, then the pump can be fixed, but the positioning and fixing require two separate steps which reduces productivity
Solution Approach 1:
The collar is designed to combine positioning and fixing functions into a single integrated component. The collar simultaneously positions the pump in the correct location and secures it through deformation, eliminating the need for separate positioning and fixing operations.
Solution Approach 2:
The collar performs preliminary positioning action before final fixing. The collar first positions the pump correctly, then deforms to secure it, ensuring proper alignment is achieved before the fixing process completes.
2Ease of operation
If the pump is positioned in the neck opening prior to fixing, then the positioning can be adjusted, but the pump becomes unstable due to dip tube deformation
Solution Approach 1:
The collar acts as an intermediary element between the pump and the neck. It provides a stable interface that supports the pump during positioning and maintains stability throughout the fixing process, preventing displacement caused by dip tube deformation.
Solution Approach 2:
The collar provides preliminary support and stabilization to the pump before the final fixing deformation occurs. This preemptive support prevents instability and potential misalignment that would result from dip tube elastic deformation.
3Reliability
If the dip tube rests against the reservoir bottom during positioning, then the supply function is ensured, but it creates tilting force that destabilizes the pump
Solution Approach 1:
The collar serves as a mediator that decouples the dip tube's contact with the reservoir bottom from the pump's positioning stability. By providing external support through the collar, the system allows the dip tube to rest on the bottom for supply function while preventing the resulting forces from destabilizing the pump.
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 provides stable pump positioning and secure fixing, reducing the risk of leakage and mechanical instability, even in challenging bottle geometries, by using a deformable collar with gadroons and a sliding ring to maintain the folded claws, ensuring reliable dispensing.
Implementation Method 1
the collar can be made of deformable material, especially aluminium, so that it can be deformed by crimping under the collar
Implementation Method 2
the dip tube is then slightly elastically deformed, and the release of this deformation after positioning exerts a force on the pump

AI summary
The bottle has a collar (12) with an external skirt (13) including a lateral wall (16), where the wall has a nominal internal diameter provided to surround a lateral wall (17) of a neck (2) i.e. shoulder neck, for positioning a pump on an upper opening of the neck. The skirt is deformable on the neck to sealingly fix the pump on the neck, where the wall of the skirt includes a gadroon (21) i.e. slide, retaining the pump in the opening during deformation of the skirt. The gadroon is projected relative to the internal diameter to form an inscribed diameter lower than diameter of the wall (17).
