My invention relates to wooden containers,
such, for example, as barrels, tubs and the like,
provided with removable tops or end members.
Said containers normally are ?lled with material,
and the end member is then secured in place.
It is necessary that said end member be ?tted
tightly in place to prevent spilling, and yet it is
desirable that said end member be removable
without injuring, substantially, the side of said
