Solution Overview

Problem

Existing systems for fixing dispensing pumps on bottles are either irreversibly attached, making recycling difficult, or use screwable sleeves that are inconvenient and costly to install, with potential for product degradation and aesthetic issues.

Innovation Solution

A system comprising a sleeve with an inner collar and a lower skirt, a hoop that slides to constrain the skirt for secure fixing, and an outer collar that moves between use and dismantling positions, allowing for almost irreversible separation while maintaining aesthetics and simplicity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid hoop is used to constrain the skirt for secure fixing, then the fixing reliability is improved, but the ease of separation for recycling deteriorates

Engineering Contradiction:
Improvefixing reliabilityVSAvoidease of separation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies the dynamics principle by making the hoop movable rather than fixed. The hoop can transition between a first position (constraining the skirt for secure fixing) and a second position (releasing the skirt for easy separation). This dynamic positioning allows the same component to serve both functions: providing reliable fixing during use and enabling easy recycling afterward.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a screwable sleeve is used to allow separation, then the ease of separation for recycling is improved, but the fixing reliability deteriorates due to potential loosening and product degradation

Engineering Contradiction:
Improveease of separationVSAvoidfixing reliability
Core Design Contradiction:
Ease of operationVSReliability

3Ease of operation

If a screwable sleeve is used to allow separation, then the ease of separation for recycling is improved, but the device complexity increases due to torque requirements and installation complexity

Engineering Contradiction:
Improveease of separationVSAvoidinstallation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the hoop movable rather than fixed. The hoop can transition between a first position (constraining the skirt for secure fixing) and a second position (releasing the skirt for easy separation). This dynamic positioning allows the same component to serve both functions: providing reliable fixing during use and enabling easy recycling afterward.

4Ease of operation

If a screwable sleeve is used, then the ease of separation for recycling is improved, but the aesthetic appearance deteriorates due to functional clearance

Engineering Contradiction:

AI summary

The system has a hoop (16) slidably mounted around a lower skirt (12) between top and bottom positions. An exterior collar (17) is mounted around an interior collar (8) of a sleeve (7) by a device that displaces the exterior collar between a bottom usage position and a top dismounting position. The hoop, at the bottom position, is attached to the exterior collar to actuate the displacement of the exterior collar towards the top dismounting position by driving the hoop relatively to the skirt on a stroke that is sufficient to release fasteners of the skirt. An independent claim is also included for a fluid product dispensing bottle comprising a body defining a reservoir for conditioning a fluid product.
