Integrated Applicator Package With Sealed Skirt to Prevent Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing packages with separate dispensing heads suffer from leakage and residual product issues, especially with non-circular designs, leading to wastage and inefficiency.
Innovation Solution
A dispensing package with an integrated applicator body, application head, and cylindrical inner bottle, featuring a large application and dispensing face, inner cylindrical skirt, and a sealing plug to minimize residual product and ensure airtight sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate dispensing head is used, then product application is enabled, but leakage occurs from joints
Solution Approach 1:
The patent combines the dispensing head and container into a single integrated unit, eliminating separate joints between components. The application head is directly formed as part of the container structure, which prevents leakage at connection points while maintaining product application functionality.
2Area of moving object
If a non-circular dispensing head is used, then application surface area is increased, but residual product increases
Solution Approach 1:
The patent employs a circular piston design within a circular container to create a non-circular application head through selective material removal or shaping. The circular piston ensures complete product evacuation without residual waste, while the shaped application head provides enhanced surface area for application. This resolves the contradiction by decoupling the piston geometry from the application head geometry.

AI summary
A dispensing package for dispensing and applying a fluid product. The dispensing package comprises an applicator body with an application head. The applicator body encompasses an inner bottle that houses the fluid product. The application head comprises an application and dispensing face, and an inner cylindrical skirt extending downward from an inner surface thereof. A screw rod assembly is located at a bottom part of the inner bottle, threadedly engaged with a piston. A dialer is rotatably attached to the inner bottle, and non-rotatably attached to the screw rod assembly. The rotation of dialer moves the piston along the screw rod assembly, dispensing the fluid product through an orifice on the applicator head. A sealing plug within the applicator body seals an inner volume of the applicator head around the inner cylindrical skirt, ensuring the fluid product flows only into the inner cylindrical skirt from the inner bottle.
