Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatically-chargeable spout type cosmetics containers have complex structures that degrade assemblability and productivity, lead to contamination and deformation of rubber pushers, and result in residual cosmetics liquid due to inefficient design, causing waste and environmental issues.
Innovation Solution
An automatically-chargeable spout type cosmetics container with a communication hole in the connecting tube, a movable communication hole opening/closing ring, and a valve to prevent cosmetics liquid from entering the pusher, along with a wiper and inclined bottom plate for residual liquid collection, ensuring equal liquid levels and efficient discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conventional automatically-chargeable spout type cosmetics container is used, then the cosmetics liquid can be automatically charged in the spout tube, but the structure becomes complex which degrades assemblability and productivity
Solution Approach 1:
The patent extracts the communication hole opening/closing ring from the complex conventional structure and positions it directly on the connecting tube. This simplifies the overall structure by eliminating unnecessary intermediate components while maintaining the automatic charging function through the communication hole mechanism.
Solution Approach 2:
The connecting tube serves multiple functions: it connects the spout tube to the container body, provides a communication hole for automatic charging, and supports the communication hole opening/closing ring. This multi-functionality reduces the number of separate components needed, simplifying the overall structure.
2Extent of automation
If the spout tube is inserted into the container body, then the cosmetics liquid can be automatically charged, but the cosmetics liquid may be introduced into the pusher causing contamination and deformation
Solution Approach 1:
The valve acts as an intermediary component between the spout tube and the pusher. It allows the cosmetics liquid to pass through during automatic charging while preventing backward flow into the pusher, thus protecting the pusher from contamination and deformation.
Solution Approach 2:
The valve is positioned and configured to prevent cosmetics liquid from entering the pusher before any contamination can occur. This preliminary protective action ensures the pusher remains clean and functional throughout the automatic charging process.
3Extent of automation
If the communication hole is always open, then the cosmetics liquid can be automatically charged, but the residual cosmetics liquid increases causing waste
Solution Approach 1:
The communication hole opening/closing ring makes the communication hole dynamic rather than static. It opens automatically when the spout tube is inserted to allow charging, then closes when the spout tube is removed to prevent residual liquid. This dynamic behavior eliminates waste while maintaining automatic charging functionality.
Solution Approach 2:
The communication hole opening/closing ring is pre-positioned on the connecting tube to automatically close after charging. This preliminary closing action prevents residual cosmetics liquid from remaining in the spout tube, eliminating waste before the product is stored or transported.
4Adaptability or versatility
If the communication hole opening/closing ring is made movable, then the communication hole can be selectively opened and closed, but the structure becomes more complex
Solution Approach 1:
The communication hole opening/closing ring is made from a flexible material that can elastically deform. This flexibility allows the ring to move and close the communication hole automatically without requiring complex mechanical actuation mechanisms, thus maintaining structural simplicity while achieving selective opening/closing functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances assemblability, prevents pusher deformation, minimizes residual liquid, and facilitates convenient automatic charging and discharge, reducing costs and environmental impact.
Implementation Method 1
a communication hole opening/closing ring (130) elastically installed at the outer peripheral surface of the connecting tube (120) such that the communication hole opening/closing ring (130) is vertically movable
Implementation Method 2
a valve (140) installed at the upper portion of the connecting tube (120), to allow air in the pusher (20) to be introduced into the spout tube (110) while preventing the cosmetics liquid of the spout tube (110) from being introduced into the pusher (20)
Implementation Method 3
a wiper (160) installed at an inner periphery of the opening (11) to wipe a cosmetics liquid attached to an outer periphery surface of the spout tube (110)
Implementation Method 4
an inclined surface formed at an upper surface of the bottom plate (12) to allow a residual cosmetics liquid to be collected

AI summary
The present invention relates to an automatically-chargeable spout type cosmetics container. The automatically-chargeable spout type cosmetics container allows air present in a pusher to be introduced into a spout tube or allows ambient air to be introduced into the pusher, but prevents a cosmetics liquid from being introduced into the pusher, by a valve installed at the spout tube, thereby preventing deformation and hardening of the pusher. The automatically-chargeable spout type cosmetics container automatically charges the cosmetics liquid in an interior of the spout tube such that the height of the cosmetics liquid charged in the interior of the spout tube becomes equal to the height of the cosmetics liquid contained in a container body through a configuration in which a communication hole formed at an outer peripheral surface of a connecting tube achieves communication between the interior of the spout tube and the container body.
