Dispensing tip assembly including foodstuff additive dispenser for pressurized foodstuff container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems for pressurized foodstuff containers lack the ability to selectively and effectively deliver foodstuff additives as a distinct layer or pattern on the dispensed product, such as whipped cream, without excessive intermixing with the primary foodstuff.
Innovation Solution
A dispensing tip assembly with a tip body and a foodstuff additive dispenser, featuring a constricted throat section creating a low pressure zone and additive outlets positioned to deliver the additive as a visible stripe or swirl, utilizing a resilient bulb and snap-fit connections for assembly, and internal structures like ramps and duckbill valves to control additive flow and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional dispensing system is used, then the primary foodstuff is dispensed, but the additive cannot be delivered as a distinct layer without excessive intermixing
Solution Approach 1:
The dispensing system is segmented into separate functional components: a primary foodstuff container and a separate additive dispenser with its own reservoir and dispensing mechanism. This segmentation allows independent control of each substance, enabling the additive to be delivered as a distinct layer rather than mixing with the primary foodstuff during dispensing.
Solution Approach 2:
The patent introduces an intermediary mechanism (the separate additive dispenser positioned at the tip assembly) that mediates between the primary foodstuff flow and the final dispensed product. This intermediary component delivers the additive at the point of dispensing, creating a distinct layer without requiring complex internal structures within the main container.
2Illumination intensity
If the additive is delivered into the internal flow passage, then it mixes with the foodstuff, but delivering it separately reduces visual appeal
Solution Approach 1:
The additive dispenser is positioned in a spatial dimension separate from the main foodstuff flow path, allowing the additive to be deposited on the surface or as a distinct layer rather than being forced into the internal flow passage. This dimensional separation maintains visual appeal while ensuring efficient additive delivery through dedicated dispensing outlets.
3Stress or pressure
If a constricted throat section is created, then a low pressure zone is formed for additive delivery, but the cross-sectional area is reduced
Solution Approach 1:
The constricted throat section creates a localized low-pressure zone at a specific position within the flow passage, rather than reducing the cross-sectional area throughout the entire passage. This local modification allows the additive to be drawn into the flow at the constriction point while maintaining adequate flow area elsewhere in the system.
Solution Approach 2:
The patent utilizes pressure differential principles (pneumatics/hydraulics) where the constricted throat section creates a low-pressure zone that draws the additive into the foodstuff stream. This pressure-based mechanism enables additive delivery without requiring mechanical pumps or complex actuation systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the selective and efficient delivery of foodstuff additives as a distinct layer or pattern on the dispensed product, enhancing visual appeal and flavor experience while minimizing intermixing with the primary foodstuff.
Implementation Method 1
The internal flow passage has low pressure zone in which fluid pressure is lower than fluid pressure upstream of the low pressure zone as the flowable foodstuff from the foodstuff container flows through the internal flow passage toward the open downstream end
Implementation Method 2
duckbill valves tethered to one another, and/or a plurality of injection ports and/or structure for one-direction dispensing

AI summary
A dispensing tip assembly includes a foodstuff additive dispenser for a pressurized foodstuff container. A tip body of the dispensing tip assembly may have low pressure zone in which fluid pressure is lower than fluid pressure upstream of the low pressure zone as flowable foodstuff from the foodstuff container flows through the internal flow passage toward an open downstream end of the tip body. The dispenser tip assembly may include one or more of duckbill valves tethered to one another, and/or a plurality of injection ports and/or structure for one-direction dispensing, and/or internal fins to couple to an actuator of the foodstuff container, and/or an anti-rotation device, and/or a collar for attaching a bulb or pod of the tip body, and/or an ergonomic and functional bulb.
