Packaging Design With Textured Base For Solid Product Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for solid products, such as thermoformed blister packs and shrink wrapped films, pose challenges in handling and stability due to direct contact risks and moisture absorption, leading to softening or dissolution, especially in humid conditions, which affects handling and dispensing consistency.
Innovation Solution
A packaging design featuring a base with textured, grippable surfaces and a peelable lid that allows for safe loading and inversion without direct contact, combined with a moisture barrier to prevent humidity absorption, ensuring the solid product remains stable during storage and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If shrink wrapped films with small holes are used for packaging solid products, then air evacuation during shrinking is enabled, but moisture from the atmosphere enters the package causing the solid product to swell and dissolve
Solution Approach 1:
The patent employs a flexible shrink-wrapped film as the packaging shell that conforms to the solid product shape. The film is designed with controlled permeability properties to allow air evacuation during shrinking while preventing moisture ingress, resolving the contradiction between manufacturability and moisture protection.
2Productivity
If solid products are dispensed using spray-type dispensers, then concentrated use solution is removed from the solid product surface, but if the solid product is softened or liquefied, the aqueous concentrate use solution becomes too concentrated
Solution Approach 1:
The packaging design includes a receptacle with specific geometric features (sloped surfaces, ledges) that prevent the solid product from becoming softened or liquefied before dispensing. By maintaining product integrity in advance, the dispensing process achieves consistent concentration without requiring corrective measures.
3Stability of the object's composition
If the solid product is allowed to absorb humidity during storage, then the solid product softens or dissolves, but preventing humidity absorption requires effective moisture barrier properties
Solution Approach 1:
The packaging utilizes composite material construction with a moisture-barrier film as the primary protective layer. The film is sealed to the receptacle to create a composite packaging system that provides effective humidity protection while maintaining structural simplicity and ease of use.
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 packaging design enables safe handling and consistent dispensing of solid products by preventing direct contact and maintaining product stability through effective moisture barrier properties, reducing weight gain and maintaining product integrity over time.
Implementation Method 1
A texture is on the exterior surface of the base, whereby the texture enhances a user's ability to grip the base when the base is inverted
Implementation Method 2
The seal interconnects the top of the base and the lid and allows the lid to be peeled away from the top of the base
Implementation Method 3
The solid product is allowed to slide out of the cavity into the solid product dispenser

AI summary
A product packaging for a solid product comprises a base, a lid, and a seal. The base has a top, sides, and a bottom forming a cavity configured and arranged to receive a solid product, and the base has an exterior surface. A texture is on the exterior surface of the base, whereby the texture enhances a user's ability to grip the base when the base is inverted. The seal interconnects the top of the base and the lid and allows the lid to be peeled away from the top of the base.
