Solved Clear Inventory [Trash]

So I need to make a Trash sign for my Server but this is the problem I'm getting.

When I put something into the Trash sign it saves where I want it to clear every time I open it. Anyway I can do this

My Code (Main Class)

Code:java

    private Bin bin;
 
    public void onEnable() {
 
        bin = new Bin(this);
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
    }
 
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
        Player player = e.getPlayer();
 
        if(!(e.getAction() == Action.RIGHT_CLICK_BLOCK)) return;
 
        if(e.getClickedBlock().getState() instanceof Sign) {
            Sign s = (Sign) e.getClickedBlock().getState();
            if(s.getLine(1).equalsIgnoreCase("§lTrash")) {
                bin.show(player);
            }
        }
 
    }

My Code (Menu Class)

Code:java

    private Inventory inv;
 
    @EventHandler
    public void onSignChange(SignChangeEvent e) {
        if(e.getLine(0).equalsIgnoreCase("[Trash]")) {
            e.setLine(0, "");
            e.setLine(1, ChatColor.BOLD + "Trash");
        }
    }
 
    public Bin(Plugin p) {
        inv = Bukkit.getServer().createInventory(null, 36, "Trash Bin");
 
        Bukkit.getServer().getPluginManager().registerEvents(this, p);
    }
 
    public void show(Player p) {
        p.openInventory(inv);
    }
