The collection device that is used only once is a subset of device. Each element of device that is used only once is a device which is intended to be used only once in its primary or intended function. In many cases, it will be impossible to use the device again because of some effect of its use which destroys its ability to perform its function. In some cases, it may be physically possible to use the device again, but normally it wouldn't be re-used. Examples include instances of hand grenade and condom. For stuff-like products that are 'used up', see consumable product.
