Multi-Stack Wet Wipe Package to Reduce Material and Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wet wipe packages require multiple packs for different users and uses, leading to increased resource consumption, weight, and the risk of reduced liquid impregnation due to multiple open packs.
Innovation Solution
A single package containing two stacks of fabric-based wet wipes, each with its own liquid formulation and potentially different fabric, accessible through a central orifice, which is resealable and air- and water-tight, reducing the need for secondary packaging and allowing for multifunctional use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate packs of wet wipes are used for different users and purposes, then each pack can be optimized for its specific function, but the total weight and packaging material increase significantly
Solution Approach 1:
The patent combines multiple stacks of wet wipes with different fabric formulations (e.g., baby wipes, adult wipes, exfoliating wipes) into a single shared package. This merging approach maintains functional versatility by providing different wipe types while reducing total packaging material and weight compared to separate packs.
Solution Approach 2:
The package structure is designed to serve multiple functions by accommodating different types of wet wipes within a single package. The universal package design allows one package to replace multiple specialized packs, providing adaptability for different users and purposes without increasing weight.
2Reliability
If multiple separate packs are carried around, then each pack can be kept sealed until needed, but the total packaging material and resource consumption increase
Solution Approach 1:
The package internally segments different types of wet wipes into separate stacks while sharing a common external package. Each stack remains organized and accessible individually, allowing reliable liquid impregnation retention for each wipe type while using one shared package structure instead of multiple separate packages.
Solution Approach 2:
Multiple wipe stacks share a single package structure, reducing total packaging material while maintaining the reliability of liquid impregnation through the shared air- and water-tight sealing system.
3Loss of substance
If a single package contains multiple stacks of different wipes, then packaging material is reduced, but the package structure becomes more complex
Solution Approach 1:
The package uses internal dividers or positioning structures to segment different wipe stacks within the single package. This segmentation approach reduces packaging material by eliminating external secondary packaging while maintaining organized access to different wipe types through a structured internal layout.
4Adaptability or versatility
If multiple packs are opened and used over time, then different wipe types are accessible, but the risk of reduced liquid impregnation increases
Solution Approach 1:
By segmenting different wipe types into separate stacks within a single sealed package, the system allows users to access different wipe types without exposing other stacks to air. This maintains liquid impregnation reliability while providing wipe type variety.
Solution Approach 2:
Multiple wipe stacks share a single air- and water-tight package, so opening the package once provides access to all wipe types without repeatedly exposing individual packs to air. This merging approach preserves liquid impregnation across all stacks while maintaining adaptability.

AI summary
A sanitary product, typically referred to as wet wipes, comprising: a package (20) (e.g. an envelope made of plastic film (4)), the package (20) being adapted to be resealably opened, e.g. by means of an adhesive flap (30), and being substantially air- and water-tight at least prior to initial opening of the package (20); and at least a first (A, A') and a second (B, B') stack of fabric-based wipes (7), each stack comprising multiple wipes, each wipe (7) being at least prior to initial opening of the package impregnated with a liquid formulation. Also disclosed is a method of manufacturing a sanitary product, comprising: positioning at least a first (A, A') and a second (B, B') stack of fabric-based wipes (7) onto a film (4) above an opening (6) in the film, each stack (A, A', B, B') comprising multiple wipes (7); forming the film (4) into a package (20) enclosing the at least first (A, A') and second (B, B') stacks; sealing the package (20) so as to render the package substantially air- and water-tight; incorporating an adhesive strip (30) to the package so as to form a resealable opening (6) in the package (20); and wherein each wipe (7) is impregnated with a liquid formulation at least prior to initial opening of the package (20). In embodiments, the stacks (A, A', B, B') may contain wipes made of the same or different fabrics, and may contain wipes (7) impregnated with the same or different liquid formulations. This enables a person to carry, in one package, wipes (7) both for their own use and that of their baby, while reducing weight and use of packaging.
