Dual Removable End Cap Vacuum Insulated Vessel for Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Double wall, vacuum insulated stainless steel beverage containers are difficult to clean due to limited access through a small mouth opening, and existing manufacturing methods hinder the polishing of the inner surface, as they typically have only a single removable end cap, restricting effective cleaning and insulation.
Innovation Solution
A double wall, vacuum insulated stainless steel vessel design with both top and bottom ends featuring removable, resealable end caps, incorporating a vacuum port on the exterior surface for insulation and using a fixture to align vessels during the vacuum drawing process, allowing for easier cleaning and polishing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single removable end cap design is used, then the structure is simpler and easier to manufacture, but the interior surface cannot be effectively cleaned or polished
Solution Approach 1:
The end cap is divided into two separate removable components (top and bottom), allowing access to the interior from both ends. This segmentation enables effective cleaning and polishing of the inner surface while maintaining manufacturing feasibility through standardized assembly processes
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
Facilitates easier cleaning and polishing of the interior surface, enhances insulation by allowing both ends to be opened, and enables efficient vacuum insulation of multiple vessels simultaneously, improving the usability and manufacturing efficiency of the containers.
Implementation Method 1
a double wall vacuum insulated body (12) including a vacuum port (14)
Implementation Method 2
The melt bead did not initially fit snugly into the hole, so air could escape around the melt bead during the first portion of the vacuum and heating process. However, once the temperature inside the vacuum chamber reached an appropriate threshold, the melt bead melted and sealed the vacuum port.

AI summary
A container includes: a double wall vacuum insulated body including: an electroplated stainless steel inner surface or a polished stainless steel inner surface; an outer surface including a vacuum port; a mouth located at a top end of the body having a mouth diameter; and a base opening located at a bottom end of the body having a base opening diameter; a removable top cap including a top seal that seals the top opening; and a removable bottom cap including a bottom seal that seals the bottom open.
