Cosmetic Capsule Dispensing Device with Deformable Preform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic composition packaging lacks customization options and is not suitable for small-scale distribution, potentially leading to quality and safety issues due to exposure to external contaminants.
Innovation Solution
A device that prepares cosmetic compositions in-situ by using a housing with a piston to perforate and convey capsule contents into a deformable preform, forming a receptacle while ensuring the composition's integrity and preventing contamination, along with a process that includes heating and precise capsule arrangement for customized mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cosmetic compositions are prepared in advance and packaged in customized individual containers, then shelf-life and handling are improved, but customization of quantity and contents is limited and small-scale distribution is not suitable
Solution Approach 1:
The cosmetic composition is divided into multiple separate capsules, each containing different constituents or ingredients. These capsules are then combined in a dispensing device to create customized compositions on-demand, allowing flexible quantity and content selection while maintaining the stability of individual sealed capsules for long shelf-life.
2Reliability
If cosmetic compositions are prepared in advance in customized containers, then product quality and traceability are guaranteed, but exposure to external contaminants and additional compounds cannot be prevented
Solution Approach 1:
The constituents of the cosmetic composition are pre-prepared and sealed in individual capsules before use. This preliminary sealing protects them from external contaminants during storage and transport. The capsules are only opened and combined in a controlled dispensing device when needed, minimizing exposure to contaminants while maintaining product quality and traceability.
3Quantity of substance
If a preform with deep concavity is used to form the receptacle, then the receptacle volume is increased, but the storage volume and device complexity increase
Solution Approach 1:
Instead of creating a deep concavity in the preform to increase receptacle volume, the invention uses a substantially planar preform with minimal depth. The receptacle is formed by arranging multiple capsules in a stacked configuration within the housing, utilizing the vertical dimension and capsule stacking to achieve the required storage capacity without increasing preform volume or device complexity.
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
Enables customized cosmetic composition preparation while ensuring quality and safety, minimizing volume for storage, and preventing external contamination, thus addressing the limitations of traditional packaging.
Implementation Method 1
a piston movable in translation in relation to the structure in the housing, suitable for perforating the or each capsule and conveying contents of each capsule to the outlet nozzle
Implementation Method 2
the preform has an inner surface having a concavity lower than half of a thickness of the preform, intended to be arranged facing the housing and to be deformed by the conveyance of the contents of each capsule, so as to form the receptacle
Implementation Method 3
The device as defined above comprises means for heating the or each capsule, and optionally the preform and/or mold.
