Actually I meant as a certain entity that you could potentially store other objects inside, say putting half a dozen gas masks into a box, this would be useful for distributing certain utilities across the facility, and delivering it to other areas, and if you needed something out of it, say, some ammunition, you could take it out.
Obviously it would still be a good idea to have the things despawn after some time of being out of the box as to prevent it from being used to bypass the despawn timer that prevents manufacturing personnel from creating such an absurd number of small ammo kits that it makes the 64 bit integer limit seem small.
