Disposable Liquid Container With Inverted Neck Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable containers for consumable liquids often fail to provide a hygienic and environmentally friendly solution, especially in unhygienic environments, as they require separate straws and generate excess waste.
Innovation Solution
A disposable container made from flexible, liquid-impermeable material with a hermetically sealed pouch design where the neck portion is tucked inside-out, featuring a closure that maintains hygiene and facilitates one-handed opening and use, minimizing material usage and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate straws and cellophane packaging are used for liquid dispensing, then liquid access is enabled, but hygiene is compromised and waste is increased
Solution Approach 1:
The patent combines the straw function and closure function into the same integrated structure. The neck portion serves as both the closure mechanism and the dispensing straw, eliminating the need for separate straw and cellophane components. This integration maintains hygiene by keeping the dispensing pathway sealed within the pouch until use, while reducing overall device complexity.
Solution Approach 2:
The neck portion performs multiple functions: it acts as the closure seal, the dispensing conduit, and the straw. This multi-functionality eliminates the need for separate components, reducing waste while maintaining hygienic liquid access. The single structure replaces what would traditionally require multiple separate parts.
2Loss of substance
If traditional disposable containers are used, then liquid storage is achieved, but material waste is excessive
Solution Approach 1:
By merging the closure and dispensing functions into the integrated neck portion, the patent eliminates excess material. The same plastic forms both the seal and the straw, removing the need for separate straw material and cellophane packaging, thus reducing overall material waste.
Solution Approach 2:
The container is designed to be self-sufficient with the neck portion providing both closure and dispensing functions. The user simply opens the closure to access the integrated straw, eliminating the need for separate straw packaging removal and reducing operational steps while minimizing material use.
3Loss of substance
If the neck portion is tucked inside-out with integrated closure, then hygiene is maintained and material usage is minimized, but opening mechanism complexity increases
Solution Approach 1:
The neck portion is inverted by tucking it inside-out, which creates the continuous fold that the closure secures. This inversion allows the same material to serve dual purposes as both the external closure surface and the internal dispensing pathway, improving material efficiency while the closure mechanism manages the complexity of opening.

AI summary
In one aspect, a disposable container for hygienic dispensing of a consumable liquid is disclosed. The container comprises a bag made from a flexible, liquid-impermeable material and has a flexible body portion for containing a consumable liquid and a flexible neck portion with a hermetically sealed mouth. The mouth is for dispensing the consumable liquid upon when opened. The neck portion is in a stored position, tucked inside-out inside the body portion. The tucking results in a continuous fold in the bag. The container also comprises a closure for holding together opposite sides of the bag at the continuous fold to maintain the neck portion of the bag in the stored position, tucked inside-out within the body portion, and to shield the neck portion from external contaminants pending opening or removal of the closure and eversion of the neck portion into a dispensing position.
