Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid container designs for cosmetics often fail to provide an even and predictable dispensing of products, leading to issues such as insufficient or excessive dosage, clogging, and consumer dissatisfaction, as they lack effective control over fluid flow and pressure correlation.
Innovation Solution
The development of structures and devices within the nozzle head of fluid containers that utilize a threshold fluid pressure mechanism, including retaining ridges and plugs with adjustable gap distances and materials like open-cell foam, to control fluid flow and prevent excessive dispensing, ensuring a consistent and controlled dispensing of cosmetics without dripping or clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional fluid container designs are used, then the container structure is simple, but the fluid dispensing is uneven and unpredictable leading to insufficient or excessive dosage
Solution Approach 1:
The nozzle head is segmented into multiple functional components: a plug with flow control aperture, retaining ridges for positioning, and a reservoir section. This segmentation allows each component to perform a specific function in controlling fluid flow, achieving precise dosage control through the coordinated action of simplified individual parts
Solution Approach 2:
The plug is pre-positioned within the nozzle head at a predetermined location, and the flow control aperture is pre-configured with specific dimensions. This preliminary positioning and configuration enable consistent, predictable fluid dispensing without requiring complex real-time adjustment mechanisms
2Reliability
If conventional fluid container designs are used, then the packaging is simple, but clogging of the dispensing orifice occurs due to excess product
Solution Approach 1:
The plug position within the nozzle head provides automatic feedback control for fluid flow. As fluid pressure builds, the plug responds by adjusting the effective aperture size or position, creating a self-regulating system that prevents over-pressurization and clogging without requiring external control mechanisms
Solution Approach 2:
The retaining ridges and plug configuration are designed to prevent excess fluid from reaching the dispensing orifice in the first place. By controlling the flow path and pressure distribution upstream, the design preemptively prevents the conditions that would lead to clogging
3Loss of substance
If conventional fluid container designs are used, then the manufacturing cost is low, but product waste occurs due to excessive dispensing
Solution Approach 1:
The flow control aperture dimensions, plug material properties, and retaining ridge spacing are carefully selected parameters that control the rate and amount of fluid dispensing. By optimizing these parameters, the system achieves precise dosage control that minimizes product waste while maintaining simple manufacturing processes

AI summary
In various embodiments, the invention provides enhanced structures, devices, and techniques that allow fluids and liquid products, such as cosmetics, to dispense in a more even, smoother, and more predictable manner from fluid containers. In one embodiment, a plug is inserted into the nozzle of a squeeze tube. The plug has embossments on its surface that form longitudinal openings for the tube's fluid contents to dispense in a controlled fashion. In one embodiment, a plug is positioned within at least a portion of the interior of the nozzle of a fluid container. The plug includes a tip and a base having at least one longitudinal opening structured to create a pathway for communicating fluid from the fluid repository to the dispensing orifice on at least a portion of an outside surface of the plug upon application of a threshold fluid pressure.
