Snus Container Adhesive Seal for Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers for tobacco products like snus suffer from a compromised seal between the lid and base due to wear and damage from repeated opening and closing, leading to degradation of contents and escape of odors from disposal compartments.
Innovation Solution
A container design featuring a base and lid with non-permanent reusable adhesive attachments, along with a removable rigid cover for a secondary storage compartment, ensures a resealable and airtight closure using adhesive layers on the surfaces and flexible films for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid and base are made airtight initially, then the snus freshness is maintained, but the seal becomes worn or damaged after repeated removal and replacement of the lid
Solution Approach 1:
The patent employs a disposable adhesive seal layer that is applied fresh with each lid removal. This thin, consumable adhesive layer is designed to be discarded and replaced after each use, ensuring continuous seal integrity without requiring the main lid and base structures to withstand repeated mechanical stress.
Solution Approach 2:
The adhesive seal changes its physical state from a static permanent bond to a dynamic reversible bond. The adhesive maintains strong bonding properties during storage but allows easy removal during use, and can be reapplied multiple times. This parameter change in adhesive properties enables the seal to adapt between different operational states.
2Reliability
If the cover is permanently attached to the lid, then the disposal compartment is securely enclosed, but the cover cannot be easily removed for access
Solution Approach 1:
The adhesive seal on the cover is designed as a disposable element that is applied fresh each time the cover is removed. This allows the cover to be easily detached for access while maintaining secure enclosure when closed, as the adhesive provides strong bonding during storage and easy removal during use.
Solution Approach 2:
The cover attachment system transitions from a static permanent bond to a dynamic reversible bond. The adhesive seal allows the cover to be securely attached during storage but easily removed when needed, providing flexibility in operation while maintaining containment security.
3Strength
If the adhesive is made strong for secure attachment, then the seal remains tight, but the adhesive becomes damaged or lost after repeated use
Solution Approach 1:
The adhesive seal is designed as a disposable thin layer that is applied fresh with each lid removal. This consumable adhesive maintains strong bonding properties during storage but is designed to be discarded and replaced after each use, preventing degradation from repeated mechanical stress.
Solution Approach 2:
The adhesive system is segmented into a disposable thin layer applied to the lid or base, separate from the main container structure. This segmentation allows the adhesive to be replaced independently after each use, maintaining its bonding strength without suffering from cumulative wear and tear on the main container components.
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
Maintains a tight seal and freshness of snus by allowing repeated use without adhesive loss, improving containment and reducing odor escape from disposal compartments.
Implementation Method 1
at least one of the lid and the base are attached to each other by a non-permanent reusable adhesive, and/or the cover and the lid or the base, are attached to each other by non-permanent reusable adhesive
Implementation Method 2
a flexible film may be disposed between the two portions and may be releasably attached to one of said portions using said adhesive
Implementation Method 3
the lid may be retained on the base by the lid frictionally engaging with the extending part of the plastic component
