Solution Overview
Problem
Existing fluid substance dispensing devices require simultaneous or immediate coupling of the pump with the container after filling, limiting flexibility and efficiency in the filling and coupling process.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pump is coupled to the container immediately after filling, then the hermetic closure is maintained, but the flexibility and efficiency of the filling and coupling process are limited
Solution Approach 1:
The closure system is segmented into separate functional components: a closure element with sealing lips that can be independently positioned on the container neck, and a pump body that can be coupled later. This segmentation allows the filling and coupling operations to be separated in time while maintaining hermetic closure through the independently positionable sealing lips.
Solution Approach 2:
The closure element with sealing lips is preliminarily positioned on the container neck during or after filling, establishing the hermetic seal before the pump is coupled. This preliminary action of positioning the closure element separates the sealing function from the pump coupling function, enabling flexible timing between filling and pump attachment.
2Productivity
If the pump acts as the closure for the system, then the structure is simplified, but the filling and coupling steps must occur simultaneously or immediately
Solution Approach 1:
The system separates the closure function from the pump function by introducing an independent closure element. This allows the filling operation to be completed and the closure element to be positioned, with the pump coupling occurring at a later time, thereby improving productivity through operational separation while maintaining ease of operation.
Solution Approach 2:
The closure element with sealing lips acts as an intermediary between the container and the pump, enabling the hermetic seal to be established independently of pump coupling. This intermediary component facilitates separate filling and coupling operations by mediating the sealing function, thus improving process efficiency without complicating the overall system.
3Reliability
If a hermetic closure is maintained until use, then product contamination is prevented, but the assembly and disassembly process becomes more complex
Solution Approach 1:
The closure element with elastic sealing lips is designed to self-seal when positioned on the container neck, maintaining hermetic closure without requiring complex active sealing mechanisms. The elastic lips naturally conform to the container opening, providing reliable sealing through passive elastic deformation, thus maintaining reliability while minimizing mechanism complexity.
Solution Approach 2:
The sealing lips are made of elastic material that forms a flexible sealing interface between the closure element and the container neck. This flexible sealing mechanism provides reliable hermetic closure through elastic deformation and conformal contact, achieving high sealing reliability with a relatively simple structure that facilitates easy assembly and disassembly.

AI summary
A fluid substance dispensing device includes an external container with a containment element formed of a deformable part and an essentially rigid neck featuring a first flange which abuts with a free end of the external container at one of the mouth thereof, an intermediate element with a cup-shaped part inserted into the neck and fastened to the external container so that the first flange is sandwiched between the free end and the intermediate element, the cup-shaped part including an opening in communication with an internal part of the deformable part, there being—inside the cup-shaped part—a valve element configured for displacement by the body of an airless pump so that, when the body of the pump is absent or in an unused position, the valve element is stably closed, while when the pump body is pushed into a use position, the valve element is stably open.
