Making Items Consumable

Hello there,
lastnight I attempted a project which was to make a custom potions plugin. It all worked fine however the item was not fully consumable... The itemId I used was "373, 8770, 1" it basically gave me a water bottle with the name "Mining Concoction" whenever I performed a command. I tried consuming the concoction and I recieved the effect however it did not have a glass bottle residue im new to plugin development, can anyone help me?
Thanks in Advance!

My Code so far:

PHP:

 public function onConsume(PlayerItemConsumeEvent $event){
   $player = $event->getPlayer();
   $item = $event->getItem();
   $speed = Effect::getEffect(1);
   $speed->setVisible(true);
   $speed->setAmplifier(3);
   $speed->setDuration(600);
        if($item->getId() == 373 && $event->getItem()->getCustomName() == "§k§bll§r§6Mining Concoction§k§bll§r"){
  $player->addEffect($speed);
  $player->sendMessage("§7(§3!§7)§cConcoction Consumed!");
   }
}
