Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing bottles face issues with valve tightness, particularly under air depression, and are not compatible with various outlet tube configurations, making them unsuitable for efficient and reliable refilling.
Innovation Solution
A dispensing bottle with a filling valve featuring a rigid cap and a deformable valve that maintains tightness through an intermediate passage system, allowing secure communication between the outlet tube and reservoir, and an air depression mechanism for suction filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid cap with a deformable valve is used to maintain tightness under air depression, then the reliability of the filling process is improved, but the device complexity increases due to the intermediate passage system and deformable valve mechanism
Solution Approach 1:
The valve seat is designed to be deformable, transitioning from a relaxed state (blocking the passage) to a compressed state (opening the passage). This dynamic deformation allows the valve to automatically respond to pressure changes and outlet tube insertion, maintaining tightness during storage and enabling filling during operation without complex control mechanisms
Solution Approach 2:
The valve system operates autonomously based on pressure differential and mechanical compression. When the outlet tube is inserted and air depression is applied, the valve automatically opens to allow filling. When the tube is removed, the valve automatically closes to maintain tightness, eliminating the need for external control mechanisms
2Adaptability or versatility
If a filling valve compatible with different outlet tube configurations is designed, then the adaptability is improved, but the manufacturing precision requirements increase to ensure proper sealing and compression
Solution Approach 1:
The filling valve is designed with a universal interface that can accommodate different outlet tube configurations. The deformable valve seat and compression mechanism work with various tube types (different materials, diameters, and rigidity) to achieve reliable sealing and opening, making the system compatible with multiple tube configurations without requiring model-specific valve designs
Solution Approach 2:
The valve system tolerates variations in outlet tube parameters (material, diameter, rigidity) by using a deformation-based sealing mechanism rather than a fixed geometric seal. The compression force and deformable seat adjust to accommodate parameter variations, reducing the impact of manufacturing precision requirements while maintaining sealing effectiveness
3Ease of operation
If the outlet tube is supported axially to compress the deformable valve for opening, then the ease of operation is improved, but the force required for compression increases
Solution Approach 1:
The system uses air depression (negative pressure) applied to the reservoir to assist in opening the valve. The pressure differential created by the air depression works together with the axial compression force, reducing the manual force required to compress the deformable valve seat while maintaining intuitive operation through the outlet tube insertion gesture

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 enhances the reliability of the filling process by maintaining air depression over time and accommodating different outlet tube configurations, ensuring efficient and intuitive refilling without leakage.
Implementation Method 1
a state constrained by axial support of the outlet tube on the lower bearing surface in which the seat is compressed by axial crushing of the upper bearing surface on the structure
Implementation Method 2
an air vacuum which is arranged to be able to subsequently carry out the initial filling of the reservoir with product by sealing a source of product with said tank via a valve so that said depression induces the filling of said tank by suction of the product contained in said source

AI summary
The invention relates to a dispensing bottle for a fluid product equipped with a filling valve (15) comprising a rigid cap (20) having an internal housing (21) in which a deformable valve (22) is mounted. This internal housing has a structure (24) equipped with an intermediate passage (25) formed between an upstream opening (25a) and a downstream opening (25b). The deformable valve (22) has a seat (26) equipped with an upstream passage (27) formed between a lower bearing surface (28) and an upper bearing surface (29) which is surmounted by a sealing lip (30). The valve is arranged to have a stable state in which the sealing lip (30) hermetically seals the downstream opening (25b) and a constrained state in which the seat (26) is compressed by axial crushing of the upper bearing surface (29) on the structure (24), thus allowing communication between the upstream passage (27) and the upstream opening (25a),said compression inducing a detachment of said lip to open the communication between the downstream opening (25b) and a downstream passage (23).
