Cosmetic Feeding Container Locking Structure Against Accidental Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic article storage containers risk unintentional exposure and contamination of cosmetics, leading to potential contamination of surrounding objects and the lid body.
Innovation Solution
A feeding container design featuring a lock member that locks the lid portion, allowing controlled exposure and retraction of cosmetics through axial movement and rotational mechanisms, preventing unintended opening and ensuring containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid portion is made openable for cosmetic access, then ease of operation is improved, but reliability deteriorates due to risk of unintentional exposure and contamination
Solution Approach 1:
The lock member is positioned to engage with the lid portion before the cosmetic is fully exposed, preventing unintentional opening. The locking action occurs in advance of potential contamination risk, ensuring the lid remains secured during storage and transport.
Solution Approach 2:
The lock member acts as an intermediary between the lid portion and the cosmetic container body. It mediates the opening/closing action by requiring deliberate engagement/disengagement, thereby preventing accidental lid movement while still allowing intentional access when needed.
2Reliability
If the lock member structure is added to prevent accidental opening, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional elements: the lock member with locking protrusion, the engagement groove on the lid portion, and the guide grooves. This segmentation allows each component to perform its specific function independently, simplifying the overall design while maintaining reliability.
Solution Approach 2:
The lock member is disposed inside the container body and works in conjunction with features on the lid portion. The locking protrusion of the lock member nests into the engagement groove of the lid portion, creating a compact integrated locking system that adds minimal complexity.
3Object-generated harmful factors
If the lid portion is locked to prevent contamination, then object-generated harmful factors are reduced, but ease of operation deteriorates due to additional locking steps
Solution Approach 1:
The lock member is designed to be operable by the user through simple axial movement. When the user presses the lock member axially, it automatically disengages from the lid portion's engagement groove, allowing the lid to open without requiring additional manipulation steps.
Solution Approach 2:
The lock member transitions between a locked state (where the protrusion engages the groove) and an unlocked state (where axial movement disengages it). This dynamic switching capability allows the system to provide both protection during storage and easy access during use.

AI summary
A feeding container includes a container that includes a tubular accommodating portion configured to accommodate a cosmetic and has a first opening from which the cosmetic is exposed, a lid portion configured to open and close the first opening, and a lock member configured to lock the lid portion in a state where the lid portion closes the first opening. The lid portion opens and closes the first opening in a state where the lid portion is connected to at least one of the lock member and the container. When the lock member moves in an axial direction, which is a direction in which an axis of the accommodating portion extends, with respect to the container, locking of the lid portion due to the lock member is released, and the cosmetic is allowed to be exposed from the first opening.
