Vacuum-Sealed Face Mask Packaging for Uniform Drug Impregnation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin drug solution holding bodies face challenges with impregnation unevenness, particularly with high viscosity liquids, where the drug solution does not uniformly distribute within the base material, leading to dripping and incomplete absorption.
Innovation Solution
A vacuum-sealed packaging method is employed, where the base material and drug solution are placed in a flat packaging bag with minimal air, allowing the solution to spread and permeate evenly throughout, using a chamber-type vacuum sealing machine to remove air and apply pressure for uniform impregnation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If liquid cosmetics of high viscosity are used to prevent dripping, then dripping is suppressed, but impregnation unevenness occurs where liquid cosmetics remains in part without being impregnated
Solution Approach 1:
The base material is folded in advance into a compact configuration before being placed in the packaging bag with the drug solution. This preliminary folding action creates a compressed structure that facilitates uniform impregnation when the drug solution is added, allowing the liquid to penetrate all layers evenly without remaining in pockets, thus resolving the impregnation unevenness issue while maintaining high viscosity to prevent dripping
Solution Approach 2:
The physical state of the base material is changed by folding and compressing it into a compact form, which alters its internal structure and porosity. This parameter change enables the high viscosity drug solution to penetrate uniformly throughout the compressed base material, achieving both complete impregnation and drip prevention
2Manufacturing precision
If a two-layer structure or folded base material is used to suppress impregnation unevenness, then impregnation uniformity is improved, but device complexity increases
Solution Approach 1:
The base material is divided into multiple layers through folding, creating a multi-layered compact structure. This segmentation allows the drug solution to penetrate systematically through each layer, achieving uniform impregnation without requiring complex additional components or structures beyond the folding itself
3Volume of stationary object
If the base material is stored in a folded state to make the package compact, then package size is reduced, but air pockets may form affecting impregnation
Solution Approach 1:
The folding process, which could potentially create air pockets and impede impregnation, is converted into a benefit by the subsequent vacuum sealing process. The vacuum sealing removes air from the folded structure, and the folding configuration actually facilitates uniform drug solution distribution throughout the compressed layers, turning a potential disadvantage into an advantage for achieving complete impregnation
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
This method effectively suppresses impregnation unevenness, allows for a smaller drug solution volume, and reduces package size while ensuring complete absorption of high viscosity solutions within the base material.
Implementation Method 1
a packaging bag into which a base material and a drug solution are placed is vacuum-sealed
Implementation Method 2
the drug solution spreads to every corner inside the packaging bag, and also permeates every corner inside the base material

AI summary
Provided are a package for a skin drug solution holding body capable of further prohibiting impregnation unevenness of a drug solution, and a method of manufacturing the same. A face mask package in which a base material 1 used by attaching it to skin is impregnated with liquid cosmetics 2, and the base material 1 and the liquid cosmetics 2 of high viscosity are placed in a packaging bag 3 and vacuum-sealed. The base material 1 is in a sheet form, and the sheet-form base material 1 is stored in a folded state in the packaging bag 3 as a flat bag. It is preferable that a chamber-type vacuum sealing machine is used for vacuum-sealing. It is also preferable that the packaging bag 3 having the base material 1 and the liquid cosmetics 2 therein is pressed, while being sandwiched, prior to vacuum-sealing.
