Carpenter Technology has been granted a patent for a container designed to store metal powder. The container includes a sensing device that measures the temperature and humidity inside the container. This data is compared to readings from a second sensing device outside the container to determine if the container can be safely opened. The container can communicate with the nearest available second sensing device in the storage environment. This invention ensures that the metal powder has acclimatized to its surroundings before opening the container.

Patent granted for a container with temperature and humidity sensing
A recently granted patent (Publication Number: US11679926B2) describes a container designed to store metal powder and ensure its safe handling. The container includes a sealed opening and a first sensing device that measures the temperature and humidity levels inside the container. This reading is then compared to a second reading from a sensing device outside the container, which measures the temperature and humidity levels of the surrounding environment. By analyzing these readings, the container provides users with an indication of whether the metal powder has acclimatized to its surroundings and whether it is safe to open the container.
The patent also mentions various configurations and features of the container. For example, the first sensing device can be attached to the inner surface of the container lid or the container body. The container may have a part-conical body portion, and the first sensing device can be located in this portion. Additionally, the container may have an outlet with an outlet valve, and the first sensing device can be positioned downstream of the valve to measure the conditions of the powder after it passes through the valve.
Furthermore, the container can include multiple sensing devices, such as temperature sensors, humidity sensors, and sensors for determining the dew point within the container. The patent also suggests the use of a second sensing device in an additive manufacturing machine, which can communicate with the container to provide additional readings.
The patent also describes methods for determining the safety of opening the container. For example, the temperature readings from the first and second sensing devices can be compared, and the difference between them can be used to make a determination. The patent also mentions the possibility of recording the step of determining if the container is safe to open and locking the container if it is deemed unsafe.
Additionally, the patent discusses the use of antennas or radio-frequency identification tags in the container to determine its location within a confined environment, potentially enabling better tracking and management of the containers.
In summary, this granted patent introduces a container designed to store metal powder safely. By utilizing sensing devices and comparing readings from inside and outside the container, users can determine if the powder has acclimatized to its surroundings and if it is safe to open the container. The patent also suggests various configurations and features to enhance the container's functionality and safety.
