Paper Pouch Bag with Extended Protective Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pouch-type paper bags with voluminous goods often have open ends that are exposed to weather and curious onlookers, and rolling them up requires additional paper material, which can damage the products.
Innovation Solution
A pouch-type bag design featuring a cross-type base with a sheet extending beyond the lateral edges of the plies, allowing the sheet to be folded over to cover the open end, providing protection against weather and reducing exposure, and incorporating handle strips with recesses for easier transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the open end is left wide open for easy filling, then the filling process is simple, but the products are exposed to weather effects and curious onlookers
Solution Approach 1:
The sheet is pre-attached to the first ply before filling, positioned to extend beyond the lateral edges. After filling, the sheet is folded over to cover the open end, providing protection against weather and onlookers while maintaining easy filling access during the filling process
2Object-affected harmful factors
If the open end is rolled up to protect products, then weather protection is improved, but additional paper material is necessary and products could be damaged
Solution Approach 1:
The sheet serves multiple functions: it acts as a protective cover for the open end, provides structural support for rolling, and can be integrated with handle strips. This eliminates the need for separate protective materials while protecting products from weather and onlookers
Solution Approach 2:
The sheet is combined with the first ply through attachment, and the handle strips are integrated into the sheet structure. This merging of components allows the sheet to serve both as a protective cover and as part of the handling system, reducing the need for additional separate materials
3Object-affected harmful factors
If a sheet is attached to cover the open end, then product protection is improved, but the structure becomes more complex
Solution Approach 1:
The protective structure is divided into distinct components: the sheet attached to the first ply, the handle strips integrated into the sheet, and the folding mechanism. This segmentation allows each component to perform its specific function while maintaining overall structural clarity and manageability

AI summary
The invention relates to a pouch-type bag made of paper having a first ply and a second ply, which are connected to one another on their lateral edges and form a filling space, wherein, at its closed end, the pouch-type bag comprises a block-type base or cross-type base and, at its open end via which the filling space can be filled, the lateral edges of the first and second plies terminate on the same plane, wherein at least one sheet is connected to the first ply, which sheet extends beyond the lateral edges of the first and second plies, wherein the sheet is arranged in particular on the side of the first ply facing away from the filling space.
