Solution Overview

Problem

Conventional dispenser pump nozzle structures deform under pressure, allowing air to enter the container and spoil contents due to the widening of the discharge portion, leading to ineffective content discharge.

Innovation Solution

A nozzle structure featuring an inner nozzle with an engaging groove and elastic member fixing part, combined with an outer nozzle that moves forward by content pressure, utilizing a blocking rod and elastic member to maintain a spaced discharge and prevent air inflow, allowing for modular assembly and inspection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the discharge portion is widened by content pressure in a conventional fixed nozzle structure, then content discharge is enabled, but the nozzle deforms and air enters the container causing content spoilage

Engineering Contradiction:
Improvecontent dischargeVSAvoidnozzle structural stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The nozzle is designed with a movable outer nozzle that can dynamically adjust its position. When content pressure increases, the outer nozzle moves forward along the inner nozzle, allowing the discharge hole to open and close automatically. This dynamic structure prevents deformation while enabling content discharge, as the movable design accommodates pressure changes without compromising structural integrity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The nozzle is divided into multiple segments: an inner nozzle and an outer nozzle that can move independently. The outer nozzle includes a blocking rod that can be positioned at different locations. This segmentation allows the discharge portion to be opened or closed by moving the outer nozzle relative to the inner nozzle, preventing air entry while maintaining discharge functionality.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a sealed shaft and rubber tube are fixed in the conventional nozzle, then discharge portion sealing is improved, but the discharge portion deforms under pressure allowing air inflow

Engineering Contradiction:
Improvedischarge portion sealingVSAvoiddischarge portion deformation
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

Instead of using fixed sealing components, the invention employs a movable outer nozzle that dynamically adjusts its position based on content pressure. The elastic member provides flexible sealing that adapts to pressure changes, preventing the deformation issues associated with rigid fixed sealing structures while maintaining effective sealing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sealing mechanism utilizes an elastic member whose physical properties (flexibility and elasticity) allow it to deform and adapt to pressure changes. This elastic property enables the sealing structure to maintain its sealing function under varying pressure conditions without deforming in a way that would allow air inflow.

3Ease of manufacture

If the nozzle is made as a single integrated structure, then manufacturing is simpler, but inspection and assembly are difficult reducing productivity

Engineering Contradiction:
Improvenozzle manufacturingVSAvoidassembly and inspection efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The nozzle is designed as a modular structure with separable components: an inner nozzle and an outer nozzle that can be assembled and disassembled independently. This segmentation allows for easier inspection of individual components and simplified assembly processes, improving productivity without significantly complicating manufacturing. The modular design enables quality control checks on each component before final assembly.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention relates to a combination of a dispenser pump and nozzle structure of a dispenser pump button. According to the present invention, the nozzle structure of the dispenser pump button is designed in such a way that an outer nozzle (600) comprising a discharge hole (621) forwardly moves by the pressure of the contents, and the contents are discharged through the space distanced from an inner nozzle (500), thereby preventing the deformation of a nozzle. Therefore, the inflow of air into a cosmetic container is blocked, and thus the deterioration of the contents can be prevented.
