Why is my Debounce Failing...?

As the Title says, my Debounce in a script is not working. I am probably doing something extremely stupid which I am overlooking. Anyways, here is the script.

local DefenceBush = game.Workspace.DefenceBush



DefenceBush.TouchMe.Touched:connect(function(Hit)
	if Hit.Name ~= "Handle" and Hit.Parent:FindFirstChild("Humanoid") and Hit.Parent.Humanoid.Health ~= 0 then
		local DB = false
		if DB == false then DB = true
			wait(60)
			DB = false
		end
	end
end)

All that occurs is the second a player makes contact with the Berry Bush, we check to see if It's a player that is alive and then I make my Debounce (DB) as false and check if it's false, if so, make it true then continue the script which decided randomly whether the player get 1-3 berries then a 60 second cooldown occurs and DB becomes true thus making the Berries visible. The player should not be able to receive berries when they touch the Bush during the cooldown, however they do.

Declare DB outside the function. It recreates DB everytime someone touches it.

local DefenceBush = game.Workspace.DefenceBush

local DB = false -- Moved it to here, this should prevent it from being recreated

DefenceBush.TouchMe.Touched:connect(function(Hit)
    if Hit.Name ~= "Handle" and Hit.Parent:FindFirstChild("Humanoid") and Hit.Parent.Humanoid.Health ~= 0 then
        if DB == false then DB = true
            local Plr = game.Players:GetPlayerFromCharacter(Hit.Parent)
            local Get = DefenceBush.Berries:GetChildren()
            for _, Berry in pairs(Get) do
                Berry.Transparency = 1
            end
            local More = math.random(0,5)
            local DBerry = game.ReplicatedStorage.DefenceBerry:Clone()
            local DBerry2 = game.ReplicatedStorage.DefenceBerry:Clone()
            local DBerry3 = game.ReplicatedStorage.DefenceBerry:Clone()
            if More == 3 then
                DBerry.Parent = Plr.Backpack
                DBerry2.Parent = Plr.Backpack
            elseif More == 5 then
                DBerry.Parent = Plr.Backpack
                DBerry2.Parent = Plr.Backpack
                DBerry3.Parent = Plr.Backpack
            else 
                DBerry.Parent = Plr.Backpack
            end
            wait(60)
            DB = false
            for _, Berry in pairs(Get) do
                Berry.Transparency = 0
            end
        end
    end
end)

Let me know how that works and if you have any questions!

EDIT: BlueTaslem gives a much better explanation though!
