Reusable Bag With Internal Inserts For Bottle Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bags for transporting beverage bottles are not suitable for reliably carrying heavy glass bottles without damage, as they often lead to slipping, collision, and material tear, and are not designed for multiple uses or spontaneous shopping trips.
Innovation Solution
A reusable plastic bag with internal bag inserts and holding straps, where the front and rear walls are interconnected by welding or adhesively bonded areas to form internal bag inserts that can be used for securely holding bottles, and can be easily converted for carrying other items, with features like hems and side walls for stability and larger capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beverage bottles are transported in traditional bags or rucksacks, then the bottles can be carried, but the bottles slip and collide during transport causing damage
Solution Approach 1:
The bag interior is divided into multiple compartments separated by plastic film layers that extend from the front wall to the rear wall. These compartments securely hold individual bottles, preventing them from slipping and colliding during transport. The segmentation creates dedicated spaces for each bottle, eliminating the harmful movement between bottles.
2Reliability
If carrier bags have predetermined partitioned interiors for bottles, then bottles are secured, but the bags have limited range of use for other items
Solution Approach 1:
The plastic film layers forming the compartments are made flexible rather than rigid, allowing them to be folded back or removed when bottle transport is not needed. This dynamic configuration enables the bag to adapt between two states: a compartmentalized mode for secure bottle transport and an open mode for carrying other shopping items, thus providing versatility.
3Quantity of substance
If bags are designed to carry multiple beverage bottles, then the load capacity increases, but the fabric may tear or handles may be ripped off
Solution Approach 1:
The plastic film layers divide the bag interior into separate compartments, which distribute the weight of multiple bottles more evenly across the bag structure. This segmentation prevents concentrated loads on single points, reducing the risk of fabric tearing or handle rupture while allowing the bag to carry multiple bottles.
4Ease of operation
If bags have uneven load distribution for bottles, then bottles can be placed, but the bag cannot be securely placed down without tipping over
Solution Approach 1:
The compartments created by plastic film layers provide structured spaces that guide proper bottle placement. Users can distribute bottles across different compartments to achieve balanced weight distribution, ensuring the bag remains stable when placed down. The segmented structure visually and physically guides users toward uniform load distribution.
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 solution ensures secure transport of beverage bottles without slipping or tipping, allows for uniform weight distribution, and can be used for other items, while being cost-effective and durable, with improved load capacity and wear resistance.
Implementation Method 1
the front wall and the rear wall are, in the region of the first and second side edges and the base edges thereof, interconnected at least in portions, in some cases by way of welding, so as to form opposite first and second bag edges and a bag base edge
Implementation Method 2
the plastic film layer of the front wall and/or the rear wall is connected to the inside of the front wall or rear wall at least in portions by way of at least two, in some cases three or four, welded or adhesively bonded areas

AI summary
A reusable plastic bag as well as a reusable plastic bag with holding straps have internal bag inserts for receiving items, such as one or more beverage bottles. A plastic film layer is connected to the inside of a front wall and/or rear wall of the plastic bag, at least in portions, by way of at least two welded areas which are spaced apart from one another and extend from a point spaced apart from a base edge of the bag towards or as far as an opening edge of the bag, so as to form the internal bag inserts, which are open towards the bag opening. The front wall and the rear wall are interconnected by a first side wall along the first side edges thereof, and the front wall and the rear wall are interconnected by a second side wall along the second side edges.
