local rewards = {
  { item = 9019, count = 1 },
  { item = 5809, count = 1 },
  { item = 8982, count = 1 }
}   

function onUse(player, item, fromPosition, itemEx, toPosition, isHotkey)
local random = math.random(1, #rewards)
player:addItem(rewards[random].item, rewards[random].count)
player:sendTextMessage(36, 'You have found '.. ItemType(rewards[random].item):getName() ..'')
player:sendTextMessage(36, 'You have found '.. rewards[random].item ..'')

Try this:
Remember to change the storage number and variable name xD

local rewards = {
  { item = 9019, count = 1 },
  { item = 5809, count = 1 },
  { item = 8982, count = 1 }
}   

local YOUR_STORAGE_NUMBER = 5000

function onUse(player, item, fromPosition, itemEx, toPosition, isHotkey)
    if player:getStorageValue(YOUR_STORAGE_NUMBER) ~= 1 then
        local random = math.random(1, #rewards)
        player:addItem(rewards[random].item, rewards[random].count)
        player:sendTextMessage(36, 'You have found '.. ItemType(rewards[random].item):getName() ..'.')
        player:setStorageValue(YOUR_STORAGE_NUMBER, 1)
    else
         player:sendTextMessage(MESSAGE_EVENT_ADVANCE, "You already opened this chest.")
    end
    return true
end
