Deodorant Dispenser Refill Cartridge Puncture Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deodorant dispensers are not designed for efficient material reuse, as once the deodorant composition is depleted, the entire dispenser must be discarded, leading to wasteful disposal of materials.
Innovation Solution
A deodorant dispenser system comprising a refill cartridge with a puncturable seal and a body with a device for puncturing the seal, allowing the refill cartridge to be connected and used, thereby extending the life of the dispenser and reducing material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire dispenser is discarded after the deodorant composition is depleted, then the dispenser ensures complete replacement of the consumable, but the material from which the dispenser is made is wasted
Solution Approach 1:
The dispenser is divided into two distinct segments: a reusable dispenser body and a disposable refill cartridge. The refill cartridge contains the deodorant composition and is replaced when depleted, while the dispenser body remains in use. This segmentation allows the consumable portion to be fully replaced while preserving the non-consumable dispenser structure, thereby eliminating material waste while ensuring complete consumable replacement.
2Loss of substance
If a refill cartridge system is implemented, then material reuse efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The dispenser is divided into two distinct segments: a reusable dispenser body and a disposable refill cartridge. The refill cartridge contains the deodorant composition and is replaced when depleted, while the dispenser body remains in use. This segmentation allows the consumable portion to be fully replaced while preserving the non-consumable dispenser structure, thereby eliminating material waste while ensuring complete consumable replacement.
Solution Approach 2:
The refill cartridge is pre-filled with deodorant composition and pre-sealed before use. This preliminary preparation allows the user to simply attach the pre-prepared cartridge to the dispenser body without needing to fill or prepare anything, maintaining ease of use despite the added structural complexity of the refill system.
3Ease of operation
If the seal is made puncturable, then the refill cartridge can be easily activated, but the seal may be compromised before use
Solution Approach 1:
The seal is pre-positioned and pre-configured in a specific orientation within the refill cartridge during manufacturing. The puncture device on the dispenser body is also pre-positioned to align with the seal's weakest point. This preliminary arrangement ensures that when the cartridge is attached to the dispenser, the puncture occurs automatically and reliably at the intended location, enabling easy activation while maintaining seal integrity until that moment.
Solution Approach 2:
The seal is designed with non-uniform properties: it has a generally strong structure to maintain integrity during storage and handling, but includes a localized weak point or designated puncture zone that is easier to penetrate. This local variation in seal quality allows the puncture device to easily breach the seal at the intended location while the rest of the seal remains strong and reliable until activation.

AI summary
Disclosed is a deodorant dispenser refill cartridge, comprising: a container defining a chamber storing a fluid deodorant composition and having an opening through which the composition is dispensable from the chamber; and a seal sealing the opening. Also disclosed is a deodorant dispenser, comprising: a body having a cavity for receiving a first portion of the refill cartridge; a device within the cavity and extending along at least a portion of an edge region of the cavity for puncturing the seal of the refill cartridge as the first portion of the refill cartridge is received in the cavity of the body; and an applicator for applying the fluid deodorant composition to a user at an exterior of the dispenser.
