Press Dispensing Container With Airtight Low-Protrusion Product Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing containers for solid, semi-solid, or waxy personal care products are complex, costly, and inefficient in terms of usability and airtight storage, particularly as they struggle to accommodate softer product compositions and prevent product protrusion during application.
Innovation Solution
A press-type dispensing container with a hollow tube portion and a compressible region, featuring an inner member with a support portion and a flexible or fluid drive element that migrates to dispense the product when compressed, allowing for streamlined design and airtight storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional tube-type designs are used for solid, semi-solid, or waxy personal care products, then the package structure is simple, but the product must protrude minimally to prevent breaking, requiring complicated parts and assemblies
Solution Approach 1:
Instead of rotating the outer shaft as in traditional designs, this invention inverts the operation by having the inner member rotate while the outer shaft remains stationary. The inner member includes a support portion that rotates to dispense product, while the outer shaft serves only as a housing. This inversion simplifies the overall structure by eliminating the need for complex rotation mechanisms in the outer shaft.
Solution Approach 2:
The package is divided into distinct functional segments: an outer shaft that provides structural housing, an inner member that handles product support and rotation, and a cap that seals the product. This segmentation allows each component to be optimized independently, reducing overall complexity while improving dispensing functionality.
2Reliability
If the product protrudes minimally from the package to prevent breaking, then product integrity is maintained, but the package requires complicated parts and assemblies
Solution Approach 1:
The inner member is designed to be dynamically adjustable, allowing it to extend or retract relative to the outer shaft. This dynamic configuration enables the product to protrude only when needed for application, while retracting when not in use to prevent breaking. The inner member includes a support portion that can move axially, providing controlled product exposure without requiring complex protective mechanisms.
3Adaptability or versatility
If personal care products use softer compositions, then product performance improves, but air-tight packaging becomes difficult to accomplish
Solution Approach 1:
The cap is designed with flexible sealing surfaces that can conform to the product shape, creating an effective seal even with softer compositions. The inner member includes a support portion with a flexible seal that interfaces with the cap, ensuring air-tight closure. This flexible sealing approach accommodates various product consistencies while maintaining packaging integrity.
4Ease of operation
If traditional rotation-based dispensing is used, then product can be dispensed, but the package structure becomes complicated
Solution Approach 1:
The inner member serves multiple functions: it supports the product, provides the rotation mechanism for dispensing, and acts as a seal against the cap. By consolidating these functions into a single component, the invention eliminates the need for separate rotation mechanisms, support structures, and sealing elements, thereby simplifying the overall package structure while maintaining ease of operation.
