Double-Walled Container With Embossed Outer Sidewall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers have gaps between the outer and inner sidewalls and require additional stacking means, making them less hygienic and difficult to stack properly.
Innovation Solution
A container design with an embossed outer sidewall that extends radially from the inner sidewall, featuring a flat lower end that serves as a stacking means, eliminating gaps and the need for additional stacking aids, and incorporating a conical inner sidewall with a bended rim and a heat-sealable, moisture-resistant coating for enhanced hygiene and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional stacking means are provided, then containers can be stacked properly, but device complexity increases
Solution Approach 1:
The patent combines the stacking function with the existing outer sidewall structure by adding embossed shapings that extend radially outward. The lower end of these shapings forms an integrating stacking means that is part of the outer sidewall itself, eliminating the need for separate stacking components while maintaining proper stackability.
Solution Approach 2:
The outer sidewall's embossed shapings serve dual purposes: they provide structural integrity and insulation while their lower ends automatically form the stacking means. The structure serves itself by incorporating the stacking function into its own geometry without requiring additional dedicated stacking components.
2Ease of manufacture
If a gap exists between outer and inner sidewalls, then manufacturing is easier, but hygiene is compromised due to debris accumulation
Solution Approach 1:
The patent extracts the problematic gap between outer and inner sidewalls by having the outer sidewall extend down to contact the table surface. The embossed shapings on the outer sidewall create channels that prevent debris accumulation, effectively removing the hygiene issue while maintaining manufacturing simplicity.
3Stability of the object's composition
If outer sidewall extends to the bottom, then stability is improved, but insulation performance decreases
Solution Approach 1:
The patent applies different qualities to different parts of the outer sidewall: the main body extends to the bottom for stability and proper stacking, while the embossed shapings create insulating channels in specific locations. The shapings extend partway down the sidewall, providing localized insulation where needed while maintaining overall structural stability.
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 a gap-free, hygienic container that is easily stackable without additional means, providing effective insulation and ease of denesting, while being made from plastically deformable materials like paper or plastic for versatility.
Implementation Method 1
These embossments, together with the outer circumferential surface of the inner side wall, define channels in which gas is entrapped
Implementation Method 2
The entrapped air in the channels is an insulation, so that the surface of the container that comes into contact with the hand of a user is neither too hot nor too cold
Implementation Method 3
which makes these parts at least temporarily resistant against for example humidity, water, aqueous solutions, oil and/or fat or a combination thereof
Implementation Method 4
the individual parts of the container can be made from different materials. Especially the surface of the parts of the container that are subjected to a liquid and/or vapour are preferably provided with means, especially a coating, an impregnation, a film or the like, which makes these parts at least temporarily resistant against for example humidity, water, aqueous solutions, oil and/or fat or a combination thereof. Preferably the above-mentioned means are also heat-sealable

AI summary
The present invention relates to a container comprising a bottom (2) at the lower end of an inner sidewall (3) and an outer side wall (4), which is attached to the outer circumference of the inner side wall, wherein the outer sidewall comprises a multitude of embossed shapings (5), which extend radially out of the outer surface of the second sidewall and wherein the lower end of the shaping is distant from the lower end of the outer side wall.
