Inset Neck Container Pump Assembly Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plastic containers with external mechanisms like pumps face inefficiencies in volume use and design freedom, leading to increased transport costs and compromised product design aesthetics.
Innovation Solution
A container design featuring an annular neck inset within a concavity, allowing for a hand-operated pump assembly to be seated partially inside, reducing external volume and visual impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand pump mechanism is integrated into a plastic container, then the deposition function is improved, but the external volume is increased
Solution Approach 1:
The pump assembly is nested within a recess in the container body, with the pump head partially inset from the top surface. The pump mechanism is positioned inside the container's internal volume, utilizing the container's own space to accommodate the deposition mechanism without increasing the overall external dimensions.
2Ease of operation
If a protruding pump mechanism is used, then the deposition function is provided, but design freedom is reduced
Solution Approach 1:
The pump assembly is integrated into a recess in the container body, allowing the container to maintain its aesthetic design without being constrained by a protruding mechanism. The pump head can be positioned at various depths within the recess, enabling design flexibility while preserving the deposition function.
3Volume of moving object
If the pump assembly is seated partially inside the container, then the volumetric impact is reduced, but the manufacturing complexity is increased
Solution Approach 1:
The pump assembly is divided into separate components (pump head, pump body, mounting elements) that can be manufactured independently and then assembled into the recess. This segmentation allows for simplified manufacturing of individual parts while achieving the complex integrated configuration of the pump partially inset from the container surface.

AI summary
A container comprising concavity in which a container neck is situated, inset from the top of the container, such that a pump assembly may be fastened to said inset neck resulting in a more discreet form, a container design that is less overpowered by protruding a protruding pump, and a more volume-efficient assembly. Additionally, space between the pump assembly and a peripheral wall of said concavity is reserved such that an annular wall of a pump head may move within said space when the pump head is pressed to dispense the contents of the container.
