Abstract: This involves a device (1) and a method for the semi-automatic filling with sand (2) and water (3) of containers (5) for packaging bloodworms. The device comprises a removable drawer (6) for retaining at least one row (4) of said containers (5) placed side by side, a tank (7) for storing dry sand, reservoirs (15, 16) for retaining determined doses of sand, means (11, 12) for moving the reservoirs between a position for filling a reservoir by gravity from the storage tank and a position for emptying a reservoir for the discharge of a dose of sand by gravity directly into a corresponding container, a tank (18) for retaining water, and water-supply means (25) arranged to supply each container with a determined quantity of water.

Abstract: This involves a box, a box stack and a packaging for storage boxes for bloodworms, made of substantially parallelepipedal plastic. Each box comprises a container for retaining the bloodworms and their medium of isosceles trapezoidal section and having a surround the periphery of which is perpendicular to the bottom at a distance from the outer face of the lateral walls and with a height of between ¼ and ? of the height of said container. The surround comprises stiffening lugs with a length greater than its height, arranged so that, when the upper container is fitted onto a lower container, the resting of the lugs of the upper surround on the top of the lower surround provides on the one hand a space for retaining the worms and their medium between the lower face of the upper container and the upper face of the lower container and, on the other hand, a zigzag empty space between the volume of air trapped between said faces and the outside of the containers.
