Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper containers with silicone-modified polyolefin-based resin sealant layers struggle with non-uniform liquid removal properties, particularly for viscous liquids, leading to prolonged residue and increased costs.
Innovation Solution
A paper container design featuring foldable panels with specific crease lines and folding techniques to minimize gaps, allowing easy squeezing out of liquids regardless of viscosity, using a thermoplastic resin laminated carton blank with auxiliary folding crease lines to facilitate seamless folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sealant layer containing silicone-modified polyolefin-based resin is used, then liquid removal is improved, but the liquid removal property becomes non-uniform for different viscosities and cost increases
Solution Approach 1:
The patent changes the physical parameters of the sealant layer by controlling the weight ratio of non-modified polyolefin-based resin to silicone-modified polyolefin-based resin within 95:5 to 50:50. This parameter optimization ensures uniform liquid removal properties across different liquid viscosities while maintaining cost effectiveness, resolving the contradiction between improved liquid removal and uniformity.
2Productivity
If the paper container is designed with folding creases for squeezing, then viscous liquid removal is improved, but the structure becomes more complex
Solution Approach 1:
The patent segments the side panels by introducing specific folding creases (first auxiliary folding creases extending from bottom corners, and second auxiliary folding creases extending vertically) that divide the panels into manageable sections. This segmentation enables effective squeezing to remove viscous liquids while maintaining reasonable structural complexity through systematic crease placement.
Solution Approach 2:
The folding creases are pre-formed during manufacturing, creating preliminary fold lines that guide the squeezing action. This preliminary preparation of the folding structure eliminates the need for complex real-time manipulation during liquid removal, resolving the contradiction between effective viscous liquid removal and structural simplicity.
3Loss of substance
If silicone is added to improve liquid removal, then the amount of remaining liquid is reduced, but cost increases
Solution Approach 1:
The patent optimizes the composition parameters of the sealant layer by specifying weight ratios of non-modified polyolefin-based resin to silicone-modified polyolefin-based resin within 95:5 to 50:50. This parameter control achieves effective liquid removal with minimal residue while managing the cost impact of silicone addition, resolving the contradiction between reduced remaining liquid and manufacturing cost.

AI summary
In order to obtain a paper container that can easily pour out a liquid matter from the paper container in a short time with as little residue of the liquid matter as possible, in a body left side panel (7) contiguous with a gable wall forming panel (23) of a gable roof-type paper container (1), an imaginary base point (A) is set on an imaginary vertical line laterally bisecting the body left side panel (7) at a center of the body left side panel (7), and is set at a position distant by a half of a length of a bottom portion horizontal folding line (36) from a middle position in a length direction of the bottom portion horizontal folding line (36) at a lower end of the body left side panel (7). The body left side panel (7) has: first auxiliary folding crease lines (42) extending toward both ends of the bottom portion horizontal folding line (36) from the base point (A); a second auxiliary folding crease line (43) extending vertically from the base point (A) toward a top portion horizontal folding line (25); and a third auxiliary folding crease line (44) extending horizontally from the base point (A) to the body front panel (6) side to reach the body front panel (6) across a body vertical folding line (4) of the body front panel (6).
