Product Dispenser with Segmented Reservoir for Uniform Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product dispensers fail to ensure even and controlled distribution of elongate product strips, such as skincare creams and lotions, resulting in uneven application.
Innovation Solution
A product dispenser comprising a container with a flow regulator and dispensing cover that creates an elongate distribution slit, allowing for controlled dispensing of a uniform product strip through a reservoir, ensuring even distribution and consistent thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional product dispenser is used, then the product can be dispensed, but the distribution of the elongate product strip is uneven and uncontrolled
Solution Approach 1:
The flow passage is divided into multiple sections with different aperture configurations. The reservoir is segmented into multiple outlet apertures arranged in a specific pattern, which segments the product flow into controlled streams that recombine to form a uniform elongate strip. This segmentation allows precise control over product distribution while maintaining ease of operation.
Solution Approach 2:
The reservoir acts as an intermediary component between the flow passage and the dispensing opening. It receives product from the flow passage and redistributes it through multiple apertures in a controlled manner, ensuring even distribution of the elongate strip. The reservoir mediates the transition from constrained flow to free dispensing while maintaining uniformity.
2Productivity
If the product flow is increased to improve dispensing speed, then productivity increases, but the uniformity of the product strip thickness decreases
Solution Approach 1:
The invention changes the geometric parameters of the flow passage and reservoir apertures to optimize both flow rate and uniformity. By adjusting the size, shape, and arrangement of multiple apertures in the reservoir, the system achieves high dispensing speed while maintaining consistent product strip thickness. The parameter optimization allows simultaneous improvement of productivity and precision.
Solution Approach 2:
The reservoir apertures are arranged in a two-dimensional pattern that transforms the one-dimensional flow from the flow passage into a distributed two-dimensional flow pattern. This dimensional transformation ensures that product is distributed uniformly across the width of the elongate strip while maintaining high flow rates, thus improving both productivity and thickness consistency.

AI summary
A product dispenser for dispensing an elongate product strip includes, in one embodiment, a product container for storing the product to be dispensed, the container defining an opening through which the product can exit the container, a product flow regulator and a dispensing cover that overlies the product flow regulator. The product flow regulator is positioned proximate the container opening and comprises a flow passage that is in communication with the product container, the flow passage accommodating the product exiting the container. The product flow regulator terminates in at least one distribution aperture for allowing the product within the flow passage to exit the product flow regulator, the product flow regulator further comprising a reservoir for accommodating the product exiting the product flow regulator. The dispensing cover defines an elongate distribution slit proximate the reservoir of the product flow regulator, for allowing an elongate product strip to be dispensed.
