Compact Cosmetic Container Hermetic Sealing and Integrated Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compact cosmetic containers fail to provide reliable hermetic sealing for wet powder cosmetics, leading to moisture vaporization and cosmetic deterioration, and are inconvenient to use due to separate cosmetic-applying tools.
Innovation Solution
A compact cosmetic container design featuring a sifter with a mesh-covered discharge-hole, hermetically coupled to an inner container using a hinge-lid system with elastomer packing and anti-push protrusions, and an integrated cosmetic-applying tool receptacle, ensuring reliable sealing and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple packing structure is used to close the discharge-hole, then the device complexity is reduced, but the hermetic reliability deteriorates because it cannot provide reliable hermetic force to wet powder cosmetic containing moisture
Solution Approach 1:
The hermetic sealing system is segmented into multiple functional components: a lid body, a hermetic member with elastic deformation capability, and a hermetic packing material. This segmentation allows each component to perform its specific function - the lid provides structural support, the hermetic member provides elastic sealing force, and the packing material provides the actual seal - thereby achieving reliable hermetic sealing without excessive overall complexity.
Solution Approach 2:
The hermetic member is designed with elastic deformation properties that allow it to change its physical parameters (shape and volume) in response to pressure changes during opening and closing operations. This elastic parameter change enables the hermetic member to maintain reliable sealing force on wet powder cosmetic while accommodating the dynamic conditions of container use.
2Reliability
If the sifter is hermetically sealed to prevent moisture loss, then the reliability is improved, but the ease of operation deteriorates because the cosmetic-applying tool must be used separately
Solution Approach 1:
The cosmetic-applying tool and the hermetic sealing system are merged into a single integrated structure. The tool is accommodated within the lid assembly, and the hermetic member is configured to seal around the tool when the lid is closed. This merging allows the container to maintain reliable hermetic sealing while keeping the applying tool readily accessible and integrated, eliminating the need for separate tool storage or handling.
3Ease of operation
If the outer wall surface of the sifter frame is pushed outwards by compressive close-contact force, then the ease of operation is improved for closing the lid, but the reliability deteriorates because hermetic force of the hermetic packing is lost
Solution Approach 1:
The hermetic member is pre-configured with elastic deformation capability and positioning features that counteract the outward pushing force applied during lid closing. The elastic properties of the hermetic member create a preliminary anti-action that prevents the outer wall surface from being pushed outwards, thereby maintaining hermetic force even under compressive close-contact conditions.
Solution Approach 2:
The hermetic member utilizes elastic parameter changes to adapt to the compressive forces during lid closing. As the lid is closed, the hermetic member deforms elastically to accommodate the pressure, then maintains sufficient hermetic force through its elastic recovery, preventing loss of sealing capability while allowing easy closing operation.
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 design provides a reliable hermetic seal, maintaining cosmetic quality and convenience through integrated tools, preventing moisture loss and cosmetic scattering, while allowing easy discharge and application of cosmetics.
Implementation Method 1
a hermetic locking protrusion is formed on a support wall of the inner container to correspond to the engagement recess, such that the engagement recess is elastically engaged with the hermetic locking protrusion
Implementation Method 2
a sifter coupled to an upper portion of the inner container, the sifter having a discharge-hole through which the cosmetic is discharged, the discharge-hole being covered with a mesh
Implementation Method 3
an outer cover coupled to the outer container by means of a hinge to be opened and closed; a lid coupled to the inner container by means of a hinge to be opened and closed

AI summary
A compact cosmetic container in which a cosmetic material is taken out through a sifter having a mesh using a cosmetic-applying tool, such as a puff. The sifter is reliably and hermetically coupled to an inner container in which a wet power cosmetic is accommodated. When a lid is closed, a discharge-hole formed in a frame of the sifter is efficiently closed to be airtight by a hermetic packing. The cosmetic material is prevented from leaking while the cosmetic container is carried for use. The cosmetic-applying tool provided integrally on the compact cosmetic container can significantly improve the convenience of use.
