Threaded Adapter for Herb Grinder to Mason Jar Hermetic Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage solutions for shredded cannabis herbs, such as zip-lock bags and plain jars, fail to effectively prevent moisture and environmental damage, and lack a secure method to transfer shredded herb from grinders to storage containers without loss or dispersion.
Innovation Solution
A circular adapter with a male thread for herb grinders and a coarse female thread for regular-mouth Mason jars, allowing secure attachment and transfer of shredded herb, ensuring a smooth, hermetic seal and minimizing particulate retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If shredded herb is transferred from grinder to storage container using conventional methods, then transfer process is simple, but herb components are displaced or lost and scattered
Solution Approach 1:
The adapter merges the grinder attachment and storage container into a single integrated unit. The adapter body simultaneously provides threading for grinder engagement and forms a sealed receiving chamber that directs shredded herb into the storage container, eliminating the need for separate transfer operations and preventing herb loss.
Solution Approach 2:
The adapter acts as an intermediary device between the grinder and storage container. It receives the grinder attachment, provides a sealed pathway for shredded herb transfer through the receiving chamber, and directs material into the storage container, preventing dispersion and loss during transfer.
2Object-affected harmful factors
If regular storage containers like zip-lock bags or plain jars are used, then storage is simple, but product is not protected from moisture and environmental effects
Solution Approach 1:
The adapter merges sealing functionality with the storage container by integrating a lid with gasket engagement features directly onto the adapter body. This integrated lid assembly provides hermetic sealing protection against moisture and environmental factors while maintaining a simple two-component system (adapter with lid + storage container).
3Reliability
If adapter is designed with precise dimensions to fit Mason jar rim, then hermetic seal is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The adapter applies local quality by concentrating sealing functionality at specific locations rather than requiring uniform precision throughout. The receiving chamber provides a localized seal against the grinder attachment, the flange provides a localized bearing surface against the Mason jar rim, and the lid provides localized hermetic sealing with the gasket, allowing each feature to be optimized independently.
Solution Approach 2:
The adapter uses parameter changes by providing a range of acceptable dimensions for the flange outer diameter (0.70-0.78 inches) that all achieve reliable sealing with Mason jar rims. This dimensional tolerance range maintains hermetic seal reliability while reducing manufacturing precision requirements compared to fixed-dimension designs.

AI summary
An adapter has a circular body having an outer diameter and a height, a counter-bore concentric with the outer diameter, implemented in a lower extremity of the body, having a first inner diameter from the lowest point of the body to an internal horizontal shoulder, a through bore having a second inner diameter concentric with the outer diameter from an upper extremity of the body to the level of the internal horizontal shoulder, a male thread implemented at the upper extremity of the body adapted to engage a female thread of a commercially-available herb grinder, and a course female thread implemented in the counter-bore from the lower extremity of the body to the internal horizontal shoulder, the course female thread of a form to intimately engage threads under a rim of a regular-mouth Mason jar.
