Peelable Pouch With Layered Tear Promoting Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peelable pouches for pharmaceutical products are cumbersome to open and may not be suitable for child-resistant designs, as they require complex tearing sequences that are not user-friendly, especially for non-critical products like candies or breath fresheners.
Innovation Solution
A peelable pouch design featuring multiple tear-promoting means on both layers, allowing for a 'push-and-pull' mechanism to easily access the contents, with the option to be child-resistant by varying the placement of these means, and simplified manufacturing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a peelable pouch is designed with a tear promoting slit that requires folding and tearing sequences, then child-resistant properties are improved, but ease of operation deteriorates
Solution Approach 1:
The pouch is divided into multiple layers (first layer and second layer) with separate tear promoting means on each layer. The first tear promoting means on the first layer and the second tear promoting means on the second layer can be opened independently, allowing the pouch to be opened without requiring complex folding sequences while maintaining child-resistant properties through the distributed tear promotion structure.
2Reliability
If a peelable pouch requires a complex tearing sequence with multiple steps, then child-resistant properties are improved, but device complexity deteriorates
Solution Approach 1:
The opening procedure is segmented into independent tear promotion actions on each layer rather than requiring a single complex tearing sequence. The first tear promoting means and second tear promoting means are positioned to allow independent activation, simplifying the overall opening procedure while maintaining child-resistant design.
Solution Approach 2:
The tear promoting means are pre-positioned on both layers during manufacturing, so that when the user applies force, the tearing action occurs automatically at the predetermined locations without requiring complex manual manipulation or folding sequences.
3Ease of operation
If tear promoting means are provided on both layers, then ease of operation is improved, but manufacturing complexity deteriorates
Solution Approach 1:
The tear promoting means are localized to specific positions on each layer (first tear promoting means on the first layer, second tear promoting means on the second layer) rather than being uniformly distributed. This localized approach simplifies manufacturing by requiring tear promotion features only at specific critical points rather than throughout the entire pouch structure.

AI summary
A peelable pouch (1) comprises: a first layer (2), a second layer (3), a compartment (4) for housing the product (7), the compartment (4) being formed between the first and second layers (2, 3) by peelably sealing the first and second layers (2, 3) along a compartment sealing portion (40), which extends along the proximal portion (23, 33) and along at least a part of the two lateral portions (20, 21, 30, 31) of the first and second layers (2, 3) as well as along first (24, 34) and second branch portions (25, 35), a first tear promoting means (50) provided on the first layer (2) only, a second tear promoting means (51) provided on the second layer (3) only, and a third tear promoting means (52) provided on both the first and second layers (2,3) and extending in a direction towards the location (26) where the first and second branch portions (24, 34, 25, 35) meet.
