Lightweight Single-Dose Container With Peelable Seal Membrane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-dose containers, such as sachets, tetra-packs, pouches, and glass vial bottles, face challenges in easy dispensing of viscous or pasty products, often requiring additional tools or causing messes due to lack of convenient dispensing orifices and seal mechanisms.
Innovation Solution
A lightweight, collapsible single-dose container with a flexible body, featuring a sealable first end and a second end with a protuberance and dispensing orifice, sealed by a peelable seal membrane and tab portion, allowing easy access to the product without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cap closure or lid is placed over the open end to seal the container, then the sealing function is improved, but the device complexity and ease of operation deteriorate due to requiring additional tools to puncture or open the seal
Solution Approach 1:
The seal membrane is designed to be self-peelable by the user without requiring any additional tools or apparatus. The tab portion integrated with the seal membrane allows the user to easily grip and peel back the seal, making the opening process simple and tool-free while maintaining reliable sealing until opened
Solution Approach 2:
The sealing function is extracted from a complex cap closure system and simplified to a separate peelable seal membrane that can be easily removed. This separates the sealing function from the opening mechanism, allowing the container to be opened simply by peeling back the membrane without dealing with threaded caps or complex closure mechanisms
2Reliability
If glass vial bottles are used to store products, then the product containment is improved, but the weight and fragility increase making them unsuitable for viscous products
Solution Approach 1:
The container uses a lightweight, disposable flexible body made from materials like plastic barrier laminated materials or ethylene vinyl alcohol, replacing heavy glass vials. This single-use design maintains product containment reliability while dramatically reducing weight and eliminating fragility issues
Solution Approach 2:
The container employs a flexible body made from thin film materials that are lightweight yet provide effective product containment. The flexible nature allows the container to be squeezed to dispense viscous products, unlike rigid glass vials, while the material composition ensures reliable containment of various product types
3Weight of moving object
If sachets are used as single-dose containers, then the lightweight design is achieved, but the dispensing convenience deteriorates due to lack of dispensing orifices and requiring tearing open
Solution Approach 1:
The container is segmented into distinct functional zones: a flexible body for containment, a protuberance with dispensing orifice for product delivery, and a peelable seal membrane with tab for easy opening. This segmentation allows each part to perform its function optimally while maintaining overall lightweight design
Solution Approach 2:
The protuberance with dispensing orifice acts as an intermediary between the flexible body and the user, providing a controlled opening for product dispensing. This mediator enables easy access to the product without requiring the user to tear or cut the sachet, improving dispensing convenience while maintaining the lightweight flexible body design

AI summary
A single-dose container for storing and dispensing products, the container comprises a flexible body defining an interior cavity and having an end sealable by joining a first inner side of the inner surface of the body to an opposite inner side of the inner surface of the body, a second end of the body having a shoulder and a protuberance with the protuberance defining a dispensing orifice and having a sealing edge, a seal membrane shaped to overlie the sealing edge and to cover the dispensing orifice, a tab portion extending from the seal membrane, and wherein the seal membrane is removable affixed to the sealing edge.
