Dispenser Hoop Locking via Radial Axial Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing a hoop on the neck of a bottle with a dispensing member fail to ensure secure locking due to dimensional variations in the attachment zones, particularly on glass bottles.
Innovation Solution
A method involving a hoop sleeve with locking means that snap onto the neck's shoulder, combined with a dispensing member body providing radial and axial support, ensures secure fixation by sliding the body inside the sleeve to engage the locking projections on the shoulder, preventing unclipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hoop is attached to the bottle neck using conventional methods, then the assembly can be formed, but the mechanical strength of the attachment is insufficient due to dimensional variations in the neck attachment zones
Solution Approach 1:
The invention changes the geometric parameters of the locking means (projections and recesses) to create an interference fit that compensates for dimensional variations in the neck attachment zones, ensuring consistent mechanical strength despite manufacturing tolerances
Solution Approach 2:
The locking means act as an intermediary mechanism between the hoop and the neck, providing a positive mechanical engagement that transcends the dimensional variations of the attachment zones through the dispensing member body
2Reliability
If the locking means are positioned to accommodate dimensional variations, then reliability is improved, but the device complexity increases due to additional locking components
Solution Approach 1:
The locking means are integrated into the existing hoop and dispensing member structure, combining the attachment and locking functions into a unified assembly process without requiring separate locking mechanisms
Solution Approach 2:
The locking means automatically engage through the relative movement of the dispensing member body during assembly, providing self-locking functionality without requiring additional adjustment or complex actuation mechanisms

AI summary
The method involves mounting a sleeve (14) of a hoop (11) inside an annular wall (3a) of a collar (3) by placing a locking unit (15) face to face radially with regard to a shoulder (4). A body (8) of a distribution unit (5) is made to slide inside the sleeve to place the locking unit in radial support on an external range (17) and in axial support on the shoulder so as ensure locking of the fixing of the hoop in the collar. The body of the distribution unit is placed inside of the sleeve in a pre-assembled position. An independent claim is also included for a fluid product distribution bottle.
