Single-Dose Toothpaste Units With Non-Stick Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toothpaste tubes lead to excessive ingestion and environmental waste due to their plastic composition and lack of portion control, and they fail to address the need for a single-dose packaging and application.
Innovation Solution
A single-dose oral hygiene unit is created by blending a toothpaste composition with gumming, surfactant, humectant, and other ingredients and applying a coating to prevent the oral hygiene unit from sticking together and allowing the oral hygiene unit to be easily applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional plastic toothpaste tubes are used, then toothpaste can be stored and dispensed, but excessive toothpaste is ingested and environmental waste is generated
Solution Approach 1:
The toothpaste is divided into individual single-dose units, each containing a precise pea-sized amount. This segmentation eliminates the need for portion control by the user and prevents over-ingestion, as each unit is self-contained and pre-measured.
Solution Approach 2:
The patent employs biodegradable materials instead of traditional plastic tubes. Each single-dose unit is designed to be used once and then disposed of naturally, reducing environmental waste and eliminating the accumulation of non-biodegradable plastic waste from traditional tubes.
2Reliability
If traditional plastic toothpaste tubes are used, then toothpaste can be stored, but environmental pollution occurs due to non-biodegradable materials
Solution Approach 1:
The patent changes the material parameters from traditional non-biodegradable plastics to biodegradable materials. This parameter change maintains the storage capability for single-dose units while fundamentally altering the environmental impact, allowing the packaging to decompose naturally and eliminate pollution.
3Ease of operation
If multiple single-dose oral hygiene units are stored together, then convenience is improved, but the units stick together making separation difficult
Solution Approach 1:
The patent applies a coating specifically to the outer surface of each single-dose unit. This local treatment creates a non-stick property only where needed (on the exterior surface that contacts other units), while the interior toothpaste composition remains unchanged. This resolves the sticking issue without requiring complex changes to the entire unit structure.
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 solution provides a single-dose oral hygiene unit that is easy to use, prevents sticking, and reduces environmental waste by eliminating the need for a traditional tube.
Implementation Method 1
treating an outer surface of the single-dose oral hygiene units with a coating ingredient that prevents the oral hygiene units from sticking together
Implementation Method 2
a soft, elastic consistency due to the presence of a gumming ingredient in the toothpaste composition
Implementation Method 3
the oral hygiene unit easily dissolves and foams up in the mouth with a wet toothbrush and agitation of the brushing action
Implementation Method 4
a surfactant ingredient

AI summary
A single-dose oral hygiene unit of a toothpaste composition is blended together using a method of manufacturing disclosed herein. The oral hygiene units define an outer surface that is easily manipulated with a user's fingers. The ingredients are first blended together to create a final, blended toothpaste composition. A predetermined weight of blended toothpaste composition is extruded via nozzles into a plurality of cavities defined in a mold tray. The mold tray containing blended toothpaste composition is refrigerated for a predetermined time at a predetermined temperature until the blended toothpaste composition solidifies and the single-dose oral hygiene units are formed. The units may undergo a coating process whereby the outer surface of each unit is coated with an ingredient that prevents one or more units from sticking to one another or the container in which the units are placed and dispensed from.
