How a Spring-Loaded Pocket Dispenser Works
A 1949 mechanical design for a pocket-sized container that uses a spring to push items like pills or candies to the top for easy access.
Original patent title: “Pocket article dispensing container”
A 1949 mechanical design for a pocket-sized container that uses a spring to push items like pills or candies to the top for easy access. Granted to Individual in 1952 with 69 forward citations, and it is now in the public domain.
Key facts
Coverage
What does this patent actually cover?
The device functions as a compact storage unit designed to hold a stack of flat, uniform items. It utilizes a spring-loaded platform inside the casing that exerts constant upward pressure on the contents. When the user interacts with the top of the container, the spring ensures the next item is automatically positioned at the dispensing opening, allowing for one-handed retrieval.
The gap
What does this patent NOT cover?
- Does not cover containers that rely on gravity rather than spring tension to feed items.
- Does not cover non-pocket-sized dispensing systems like large industrial vending machines.
- Does not cover electronic or automated dispensing mechanisms that require a power source.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
What made this novel
The innovation lies in the integration of a constant-force spring mechanism within a handheld, pocket-sized form factor, solving the problem of item jamming during one-handed operation.
