The present invention relates to a method, as well as a system, for filling a container (100) with an amount of liquid carbon dioxide (CO 2 ) which is partially converted into an amount of solid CO 2 into said container (100), for the purpose of maintaining one or more products, loaded into said container (100), at a defined temperature, below a defined temperature, or within a defined temperature range, which temperature or temperature range is below environmental temperature. The invention further relates to a method and a system for providing identification and traceability data determining the container (100) and its loaded one or more products, and for enabling the identification of said container (100) during transport to a particular destination.

The invention relates to a filling apparatus 200 for filling fluid such as liquefied gas into a gas container 190. The filling apparatus is configured with a holding arrangement wherefrom the gas container can hang so that the gas container is not supported by the ground, but the weight of the gas container is supported by the holding arrangement. A load sensor is arranged in the filling apparatus, e.g. in the holding arrangement so that the weight of the hanging gas container can be measured. During the filling process the weight of the gas container and, thereby, the weight of the gas filled into the gas container can be measured so that supply of the fluid can be controlled. The hanging configuration of the gas container may be advantageous for avoiding inconvenient load of the load sensor.

The present invention relates to a system (1) and method of refilling gas cylinders (3), that can be installed at retail sales establishments or on a vehicle to allow the consumer or user to directly refill an empty cylinder (3) at or near residential areas convenient to the consumer. The system (1) includes a quick coupler (9) that automatically connects with a fill valve (7) of a cylinder and a supply line (15) that extends between a reservoir (2) and the quick coupler (9) for transferring fluid to the cylinder. During a filling operation, the cylinder (3) is located within a locked compartment (4) to prevent user access. A control panel (5) allows the consumer to select a predetermined quantity of fluid to be delivered.

摘要:
A device, and a container having such a device, is provided for permitting filling the container with a predetermined weight of the fluid. The device and container include a main channel to introduce the fluid into the container at a fill pressure; a detector mechanism to detect a "filled" condition based on fluid weight; and a fluid-weight control mechanism to automatically prevent introducing fluid into the container in excess of the "filled" condition. A compression spring offsets part of the weight of a displacer such that the displacer becomes buoyant as the container becomes "filled". The displacer has a seat mechanism that sealingly engages an orifice mechanism creating a differential pressure, substantially less than the fill pressure, across a control device causing closure of the main channel. The fluid-weight control device, which is substantially independent of the composition and temperature of the fluid and of inertial effects induced in an attempt to thwart the fluid-weight control safeguard, also prevents introduction of fluid into the container as the container is non-upright. Modified embodiments utilize a pilot valve arrangement instead of the differential pressure feature. A method of practicing the invention is also provided.
