Stackable Bag Packaging with Channel System for Hermetic Seal and Easy Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hermetically sealed bag packaging is not easily and rapidly openable, and the original configuration of individual packagings in a stack is not easily recognizable.
Innovation Solution
The cover films or cover film portions include a channel system with branching channels that cross over the receiving region, allowing for easy tearing and maintaining the packaging's hermetic seal, and an incision in the edge region facilitates a single-pull opening mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bag packaging is hermetically sealed with bonded cover films, then the packaging reliability is improved, but the ease of operation deteriorates because the packaging cannot be easily opened
Solution Approach 1:
The cover film is segmented by introducing channel systems that create controlled separation zones. These channels divide the bonded film structure into regions that can be independently separated during opening, allowing the hermetic seal to remain intact in closed regions while enabling easy separation in channel regions.
Solution Approach 2:
The channel systems and incisions are pre-formed in the cover films during manufacturing. This preliminary action creates predetermined separation paths that guide the opening process, allowing users to easily open the packaging by pulling along the pre-defined channels without compromising the hermetic seal of the remaining closed portions.
2Productivity
If the bag packaging is stacked for storage, then the productivity is improved, but the ease of operation deteriorates because individual packagings cannot be easily identified or opened
Solution Approach 1:
The channel systems act as intermediary structures that extend through the stacked configuration. These channels provide a mechanical interface that allows individual packagings to be identified and opened sequentially while maintaining the compact stacked arrangement for storage and transport.
Solution Approach 2:
The stack is segmented into individually addressable units through the channel system design. Each packaging contains channels that can be independently accessed and activated, allowing users to open only the required number of doses while leaving the rest of the stack intact and identifiable.
3Reliability
If the cover films are bonded together hermetically, then the reliability is improved, but the device complexity increases due to the need for additional opening mechanisms
Solution Approach 1:
The channel systems enable the packaging to open itself through a simple pulling action. The pre-formed channels and incisions create self-guided separation paths that require no additional opening mechanisms, buttons, or complex activation systems. The user simply pulls the cover film along the channel, and the packaging opens automatically while maintaining the hermetic seal.
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 quick and easy opening of the packaging without compromising the seal, allowing users to easily identify if a dose has been taken and maintaining the stack's organization.
Implementation Method 1
During production of the hermetically sealed bag packaging, the channel system is introduced into the cover films or cover film portions by means of a laser

AI summary
A method for producing a tightly sealed bag packaging and to a tightly sealed bag packaging having at least one perforation and a receiving area surrounded by a plate-shaped edge region for the inert packaging of a product containing active ingredients, wherein the bag packaging comprises cover films or cover film segments bounding the receiving area and forming the edge region. The cover films or cover film segments are each provided with a channel system having at least one channel. The channel system crosses the part of the cover film or the cover film segment covering the receiving area. At one end, each channel is provided with a branching into two channel branches, Furthermore, a slit is arranged between the two channel branches, interrupting a peripheral edge of the bag packaging.
