Elastic Tubular Mesh for Packaging Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices, such as bottles for perfumes, face challenges with non-elastic returns on mesh coverings that hinder label affixing and are aesthetically unappealing, while existing solutions fail to provide a balance between ease of installation and label accessibility.
Innovation Solution
A tubular mesh covering with varying stitch tension and cross-sections, made from elastic yarns, ensures secure fit without obstructing label placement, featuring tighter stitches for enhanced stiffness and a seamless design with decorative patterns, held by friction and knitted knots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-elastic return is used to retain the bottle on the mesh covering, then the mesh is held securely on the packaging device, but it hinders label affixing and is aesthetically unappealing
Solution Approach 1:
The patent removes the non-elastic return component from the mesh covering design. Instead, the mesh is retained on the packaging device through friction between the mesh material and the device surface, combined with the elastic properties of the yarn that allow the mesh to conform to the device shape without requiring additional retaining elements that would block label placement.
Solution Approach 2:
The elastic yarn acts as an intermediary between the mesh and the packaging device, providing retention through friction and elastic deformation rather than through rigid mechanical connections. This allows the mesh to stay in place while maintaining accessibility for label affixing.
2Reliability
If tighter stitches are used in the second set to increase elastic stiffness and reinforce hold, then the mesh is held more securely on the packaging device, but the mesh becomes more complex to manufacture
Solution Approach 1:
The patent applies different stitch tensions to different portions of the mesh. The second set of stitches, which contacts the lower portion of the packaging device, is manufactured with tighter tension to provide greater elastic stiffness and reinforcement where needed for secure holding, while other portions maintain standard stitch tension for ease of manufacture and aesthetic purposes.
Solution Approach 2:
The mesh is divided into multiple sets of stitches with different properties. The second set of stitches has tighter tension specifically for reinforcement, while other sets have standard tension, allowing the mesh to be manufactured in sections with different characteristics that can be combined into the final product.
3Ease of operation
If the mesh extends set back from the bottom of the packaging device, then label affixing is enabled, but the mesh coverage is reduced
Solution Approach 1:
The patent modifies the axial dimension parameter of the mesh relative to the packaging device. The mesh is designed with an axial dimension that is less than or equal to that of the conditioning device, allowing it to extend set back from the bottom. This parameter change enables label affixing access while the elastic properties of the yarn ensure the mesh remains securely retained on the device.
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 mesh covering provides a secure, aesthetically pleasing fit on packaging devices while allowing easy label access, maintaining its position without additional fixing methods and ensuring effective retention through elastic properties.
Implementation Method 1
made with at least one yarn elastically deformable so as to be elastically deformable over its entire length
Implementation Method 2
The tightening of the meshes of the second set of meshes makes it possible to obtain greater elastic stiffness, which reinforces the hold of the mesh on the packaging device
Implementation Method 3
The mesh can be held on the conditioning device only by friction, and can be removed by sliding it manually towards one of the ends of the conditioning device

AI summary
The article (1) has a tubular hair net (3) surrounding two portions of a cross section of a packaging device (2) e.g. beverage bottle. The hair net is connected with a deformable polyamide wire, such that the hair net is elastically deformable over its entire length. The hair net includes mesh assemblies arranged in contact with the two portions of the device respectively. A mesh of the one of the assemblies is tightened with mesh of another assembly by fabrication.
