Dispensing Device Threaded Seal Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for stand-alone containers are difficult to manufacture and assemble, hinder product flow during mixing, and require precise geometric relationships, making them unsuitable for easy and instant mixing of contents from different containers.
Innovation Solution
A dispensing and mixing device with a connecting element that screws onto a receiving container, featuring a spout-like passage part with an opening member to tear and clear the sealing film of a stand-alone container, allowing for unobstructed mixing and direct pouring of mixed products without complete disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central cutting element and retaining element are used to open the seal, then the seal can be mechanically opened, but the device becomes difficult to manufacture and assemble
Solution Approach 1:
The patent removes the central cutting element and retaining element from the dispensing device, extracting the problematic components that caused manufacturing difficulties. Instead, it uses the container's own threaded neck to engage with the device's internal threads, allowing the seal to be opened through the natural engagement process without requiring separate cutting and retaining mechanisms.
Solution Approach 2:
The threaded neck of the container serves multiple functions: it provides structural support, enables secure attachment to the dispensing device, and facilitates seal opening through engagement. This multi-functional design eliminates the need for dedicated cutting and retaining elements, simplifying the overall device structure while maintaining reliability.
2Reliability
If a central cutting device and retaining element are positioned in the center, then the seal can be opened and retained, but communication between the inside of the capsule and bottle is hindered
Solution Approach 1:
The patent extracts the central cutting device and retaining element that were obstructing the flow path. By removing these central components, the design allows direct communication between the capsule interior and bottle interior, enabling unobstructed product flow during mixing while still achieving seal opening through threaded engagement.
3Stability of the object's composition
If the dispensing device remains attached during pouring, then mixing can be maintained, but the liquid flow is hindered
Solution Approach 1:
The dispensing device is designed as a separable system where the container can be detached from the dispensing mechanism. This segmentation allows the user to maintain the device attached during mixing to ensure proper composition, then easily detach it for convenient pouring without composition degradation.
4Reliability
If a very specific and precise geometric relationship is required between the capsule and cap, then the capsule can be retained, but the device becomes difficult to manufacture and assemble
Solution Approach 1:
The threaded neck of the container serves multiple functions including structural support, secure attachment, and capsule retention through engagement with internal threads. This eliminates the need for very specific geometric relationships between separate retention components, as the threaded engagement naturally provides both retention and alignment during normal assembly operations.

AI summary
A dispensing and mixing device designed to be fixed on an opening of a receiving container and adapted to receive an autonomous container having an opening closed by a closure film and containing an additive product to be dispensed into the interior space of the receiving container which contains a different product, is described. The device has a holding element adapted to receive and retain the autonomous container in the region of its opening, and an assembly element designed to be fixed on the opening of the receiving container and to receive said holding element by screwing.
