Spout Cosmetic Container Retractable Button Piston Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spuit-type cosmetic containers are inconvenient to use and prone to contamination, as they require manual handling that can lead to excessive or inadequate application of high-functional cosmetics, resulting in operational errors and wastage.
Innovation Solution
A spuit-type cosmetic container design featuring a retractable button and piston mechanism, where the button is controlled to move down when the cap is coupled and up when separated, ensuring precise content extraction and improved usability through a cam and anti-rotation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional spuit-type cosmetic container is used, then the cosmetic contents can be extracted, but the user must manually handle the spuit tube and button, causing inconvenience and potential contamination
Solution Approach 1:
The retractable button and piston are automatically positioned to the initial state when the cap part is coupled to the container body, eliminating the need for manual resetting. This preliminary positioning action resolves the contradiction by automating a manual step while maintaining the extraction function.
Solution Approach 2:
The cap part integrates multiple functions: it serves as the closure, the operator for活塞 movement, and the holder for the retractable button. By merging these functions into a single component, the device reduces manual handling steps while maintaining extraction capability.
2Loss of substance
If the user applies cosmetic contents directly to the palm, then application is simple, but a great amount of cosmetic contents is absorbed into the palm causing wastage
Solution Approach 1:
The spuit tube extracts only the exact amount of cosmetic contents needed for application, rather than allowing the user to dispense an excessive amount to the palm. This partial extraction principle prevents wastage while maintaining simple application.
3Reliability
If the retractable button is allowed to rotate with the cap part, then the structure is simple, but operational errors occur in the spuit operation
Solution Approach 1:
The retractable button features an asymmetric cross-sectional shape that does not match the circular rotation path of the cap part. This asymmetric design prevents rotation while allowing linear movement, providing anti-rotation control without complex additional structures.
4Reliability
If the retractable button is not stopped after moving down, then the structure is simple, but the button may be unnecessarily moved up causing errors
Solution Approach 1:
The stop structure is integrated into the retractable button itself, forming a self-contained stopping mechanism. When the button moves down, the stop structure automatically engages with the cap part to prevent further movement and unnecessary upward movement, providing operational precision without external control systems.

AI summary
The present invention relates to a spuit-type cosmetic container, and more particularly to a spuit-type cosmetic container capable of extracting an exact amount of cosmetic contents and improving convenience in use as a retractable button and a piston are moved down and fixed when a cap part is coupled to a container body by rotating the cap part, and then the retractable button and the piston are moved up so that the cosmetic contents are sucked into a spuit tube and used when the cap part is separated from the container body by rotating the cap part. The spuit-type cosmetic container according to the present invention includes a container body (110) provided at an upper portion thereof with an opening, an inner cap (132) screwed with the opening (112) of the container body (110), formed in an outer circumference thereof with a rotation annular groove (132d), and including an outer sidewall (132e) formed therein with a slit (132f), and a cylinder (132a) formed in the outer sidewall (132e), an outer cap (134) coupled to an outer portion of the inner cap (132) and provided on an inner circumference thereof with a cam protrusion (134a) and a rotation protruding wheel (134b), a retractable button (140) coupled to an inner upper portion of the outer cap (134) movably up and down within a predetermined stroke distance, and including a cam hole (142) having an oblique guide part (142a) and a stop hole (142b) formed in an outer sidewall (141), an anti-rotation step (145a) vertically formed on an inner sidewall (145), and a piston fixing rod (144) formed at a center of the retractable button (140), a piston (150) fixedly fitted to the piston fixing rod (144) of the retractable button (140) to move up and down together with the retractable button (140), an elastic member (160) fitted to the outer sidewall (132e) of the inner cap (132) to elastically support the retractable button (140), an anti-separation member (180) coupled to an inner portion of a lower end of the outer cap (134) to prevent the outer cap (134) from being separated from the inner cap (132), and a spuit tube (120) coupled to a spuit tube coupling rod 132c of the inner cap (132) to suck up a cosmetic content contained in the container body 110 (spuiting).
