Supple Pouch Receptacle for Bi-Component Paint Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging for bi-component and multi-component paint products is cumbersome, costly, and prone to errors due to separate individual packaging of components, which can lead to product loss, inaccurate dosing, and deterioration, with a lack of efficient disposable solutions for spraying tools.
Innovation Solution
A disposable receptacle system comprising a rigid outer container and a flexible inner container with an immobilizing device that allows secure locking and easy release, enabling the flexible container to contract and empty completely while maintaining a reliable seal, and optionally includes a secondary removable container for mixing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate individual packaging is used for each component, then product stability and protection from air/light is improved, but packaging bulk and cost increase
Solution Approach 1:
The patent implements nested packaging by placing the flexible inner container (holding component B) inside the rigid outer container (holding component A). This nesting arrangement allows both components to be packaged separately for stability while occupying minimal space, eliminating the need for multiple separate containers and reducing overall packaging bulk.
2Ease of operation
If multiple transfer operations are performed, then components can be moved to spraying receptacle, but risks of inversion and loss increase
Solution Approach 1:
The patent merges the storage and transfer functions into a single integrated system. The flexible inner container is designed to be directly removable from the outer container and insertable into the spray gun receptacle, creating a continuous transfer path that eliminates intermediate steps and reduces the risk of inversion and loss.
3Ease of operation
If operator performs premixing manually, then components can be combined, but preparation time and labor cost increase
Solution Approach 1:
The patent enables self-service mixing by designing the flexible inner container with a breakable seal that allows component B to be easily dispensed into the spray gun receptacle containing component A. The container's geometry and sealing mechanism are designed to facilitate automatic mixing upon insertion, reducing the need for manual intervention and preparation time.
4Productivity
If supple container is made contractible, then complete emptying is improved, but seal reliability with rigid parts deteriorates
Solution Approach 1:
The patent employs a flexible shell container made of elastomeric material that can contract completely as component B is dispensed. The flexible nature of the container allows it to collapse inward, ensuring complete emptying without compromising the seal, as the flexibility itself accommodates the volume change while maintaining contact with the sealing surface.
5Ease of operation
If detachable rigid parts are used in supple container, then component release is improved, but seal reliability between supple and rigid parts deteriorates
Solution Approach 1:
The patent extracts the sealing function from the detachable rigid cap and transfers it to the flexible inner container itself. The flexible container maintains a reliable seal with the rigid outer container throughout the entire process, and component release is achieved by breaking the seal of the flexible container rather than removing a rigid cap, thus maintaining seal reliability while enabling easy release.

AI summary
A receptacle to be fitted to a spraying tool includes an outer container, a contractible supple container housed within the outer container and containing a liquid component to be sprayed, and a removable closure member provided at the upper part of the outer container. The base of the supple container includes a locking member that is intended to protrude downwards from the underside of said base, through a through-hole provided within the base of the outer container. The receptacle also includes an immobilizing device in order to releasably lock the locking member, through said through-hole, such as to immobilize the supple container within the base of the outer container. The supple container may include at least one secondary removable container containing a product to be mixed with the liquid product contained within the supple container.
