Capsule Dispenser Valve for Moisture-Sealed Oral Care
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of packaging for portable oral care implements is due to the need for maintaining a sealed environment to preserve the integrity of moisture-sensitive oral care materials during manufacturing, packaging, shipping, and display.
Innovation Solution
A kit comprising a toothbrush and a dispenser with a housing containing capsules of oral care material, a dispensing conduit, and a valve that prevents moisture entry, allowing for the controlled dispensing of capsules onto the toothbrush, reducing the need for moisture-sealed packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed environment is used to maintain oral care material integrity during manufacturing and packaging, then the integrity of the oral care material is preserved, but the packaging cost increases
Solution Approach 1:
The packaging system is segmented into two functional parts: a moisture-sealed container for storage and a separate dispensing mechanism with valve for controlled release. This segmentation allows the oral care material to be protected during storage while enabling cost-effective dispensing without requiring continuous sealed packaging throughout the entire product lifecycle.
Solution Approach 2:
The oral care material is pre-packaged in moisture-sealed containers during manufacturing. The dispensing mechanism is pre-configured with a valve that automatically seals during storage and opens only during dispensing. This preliminary preparation eliminates the need for expensive continuous sealed packaging while maintaining material integrity until use.
2Reliability
If a sealed environment is maintained during shipping and display, then the oral care material integrity is preserved, but the packaging complexity increases
Solution Approach 1:
The invention merges the storage function and dispensing function into a single integrated unit. The container that provides moisture sealing during storage is combined with a dispensing mechanism that uses a valve to control material release. This merging eliminates the need for separate complex sealed packaging systems while maintaining material integrity throughout the product lifecycle.
Solution Approach 2:
The dispensing mechanism is designed to automatically seal during storage and open only when dispensing is required. The valve system self-regulates the sealing and opening processes without requiring external intervention or complex packaging systems. This self-service capability simplifies the overall packaging design while maintaining oral care material integrity.
3Ease of operation
If disposable oral care implements are provided without water supply, then portability is improved, but the functionality is limited
Solution Approach 1:
The invention extracts the water supply requirement from the oral care system by using a dry capsule-based dispensing mechanism. The oral care material is delivered in the form of capsules that can be dispensed without water, maintaining portability while enabling comprehensive oral care functionality through the capsule system.
Solution Approach 2:
The invention changes the physical state and delivery parameter of the oral care material from liquid/paste form (requiring water) to capsule form (waterless). This parameter change enables the oral care system to function without a water supply while maintaining full oral care functionality through the capsule-based delivery system.
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
This solution provides an economic and portable oral care solution by protecting the oral care material from moisture, thereby reducing packaging costs while ensuring the integrity of the product during distribution and use.
Implementation Method 1
a valve positioned in the dispensing conduit, the valve biased into a sealed state that prevents moisture from entering the internal chamber through the dispensing conduit
Implementation Method 2
activating the dispenser assembly, the dispenser subassembly imparting a dispensing force onto the one capsule, thereby forcing the one capsule through the valve and onto the toothbrush

AI summary
An oral care kit comprising an oral care implement and a dispenser. In one aspect, the invention can be an oral care kit comprising at least one toothbrush and a dispenser. The dispenser (300) comprises a housing (309) having an internal chamber (321) containing a plurality of capsules (310) containing an oral care material; a dispensing conduit (322) extending from the internal chamber to an exterior of the dispenser; a valve (325) positioned in the dispensing conduit and biased into a sealed state that prevents moisture from entering the internal chamber; and a dispensing subassembly (302, 315, 316, 317) configured to dispense one of the capsules from the internal chamber through the valve. The valve is forced into an open state that allows the one capsule to pass therethrough when the one capsule is subjected to a dispensing force imparted by the dispensing subassembly and automatically returns to the sealed state after the one capsule passes therethrough.
