Water bottle with printable liner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulated water bottles with foil liners suffer from distorted graphic appearances due to crinkled profiles and inefficient liquid dispensing, as the liners are loosely positioned between inner and outer shells, leading to delayed fluid dispensing when the bottle is squeezed.
Innovation Solution
A liquid dispensing container design featuring a stretchable liner positioned between a flexible outer shell and an inner core, where the liner is compressed between the two components, allowing for immediate fluid dispensing and maintaining a smooth, un distorted graphic appearance through the use of a breathable, four-way stretchable material that conforms to the container's silhouette.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a foil liner with crinkled profile is used, then the liner can be loosely positioned between inner and outer shells, but the graphics printed on the liner have a distorted appearance
Solution Approach 1:
The patent replaces the conventional crinkled foil liner with a smooth, flexible membrane liner that can conform to the container's inner surface without creating unwanted wrinkles or distortions. This flexible film maintains its smooth appearance even when positioned loosely between the inner and outer shells, thereby preserving the quality of printed graphics while allowing ease of positioning.
2Ease of manufacture
If the liner is loosely positioned between inner and outer shells, then assembly is simplified, but squeezing the outer shell merely compresses air between the shells and does not immediately squeeze the inner shell to dispense liquid
Solution Approach 1:
The patent introduces a compressible, breathable intermediate layer positioned between the outer shell and the liner. This intermediary layer acts as a mediator that transmits squeezing forces from the outer shell to the inner shell and liquid contents. When the user squeezes the outer shell, the compressible intermediate layer compresses and immediately transmits this compression to dispense liquid, while still allowing the liner to be loosely positioned for easy assembly.
3Shape
If a breathable, four-way stretchable material is used for the liner, then the liner conforms to the container's silhouette and maintains a smooth appearance, but the material must be compressed between outer shell and inner core to achieve immediate fluid dispensing
Solution Approach 1:
The patent employs a flexible membrane liner made from four-way stretchable material that can be stretched during assembly to conform smoothly to the container's inner surface. This stretchable film maintains its smooth appearance and can be loosely positioned between the shells, eliminating the need for complex compression mechanisms while still enabling immediate liquid dispensing when squeezed.
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 ensures immediate fluid dispensing and maintains a smooth, un-distorted graphic appearance, providing a comfortable grip and efficient hydration experience by compressing the liner between the outer shell and inner core, eliminating the crinkled appearance and delayed dispensing issues of conventional bottles.
Implementation Method 1
A liquid dispensing container has an outer shell including a wall having an inner surface and an outer surface. An inner core is coupled to the outer shell and has an outer surface and an inner surface that defines a reservoir configured to contain a fluid. The inner core and outer shell cooperatively define a longitudinal axis. A liner is positioned between the outer shell and the inner core. The liner comprises a stretchable material that is stretched along the longitudinal axis.
