Breachable Bubble Tabs for Tool-Free Package Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packages made from polymer films are difficult to open due to their strength, which is necessary for packaging and transportation, leading to a need for easy opening solutions.
Innovation Solution
A package design featuring breachable bubbles within tab areas that, upon pressure application, separate sealed portions of the film to create passages for easy access, allowing the contents to be opened without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the strength of the film or seals is increased to prevent rupture during packaging and transportation, then the reliability of the package is improved, but the ease of opening the package deteriorates
Solution Approach 1:
The package opening mechanism is segmented into distinct functional zones: a tab area with breachable bubbles for initiating opening, and sealed portions for maintaining integrity. The breachable bubbles are separated from the main sealed portions, allowing localized breaching without compromising overall package strength.
Solution Approach 2:
Different regions of the package have different mechanical properties. The tab area contains breachable bubbles with lower strength characteristics designed for easy breaching, while the main sealed portions maintain high strength for package integrity. This local differentiation allows the package to be both strong and easy to open.
2Volume of moving object
If polymer films are used to create tight wrapping and eliminate void space, then the volume efficiency is improved, but the ease of opening the package deteriorates
Solution Approach 1:
The breachable bubbles are pre-formed within the tab area during package manufacturing, creating predetermined weak points that facilitate easy opening. This preliminary preparation eliminates the need for external tools or forceful opening actions, resolving the contradiction between tight wrapping and ease of opening.
3Adaptability or versatility
If decorative graphics are printed on polymer films to make products more attractive, then the marketing appeal is improved, but the ease of opening the package deteriorates
Solution Approach 1:
The tab area with breachable bubbles is positioned in a location that can be distinguished from the decorative graphics area. The breachable bubbles create a functional zone with different properties than the printed surface, allowing decorative elements to maintain appeal while the tab provides easy opening functionality.
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
Enables easy and tool-free opening of packages by breaching bubbles to form passages, facilitating access to the product while maintaining the strength of the film for packaging and transportation.
Implementation Method 1
Sufficient fluid is trapped within the first breachable bubble and the second breachable bubble such that, upon application of pressure by a user to the at least one tab area, the first breachable bubble breaches
Data Source
AI summary
A package and method for opening the package are disclosed. The package includes a first film and a second film forming an enclosure and at least one tab area and defining a package periphery, the enclosure defining an interior volume configured to receive a product. The package further includes first and second breachable bubbles formed within first and second tab portions of the at least one tab area. Upon application of pressure by a user, the first and second breachable bubbles breach. The package may be alternated between a first position, wherein the first tab portion and the second tab portion are substantially sealed from each other to facilitate breaching, and a second position, wherein the first tab portion and the second tab portion are in fluid communication with each other.
