Glass hollow stoppers are used for sealing flasks and vessels. The flattened top makes removing easy. The hollow glass construction is more prone to breaking, but the glass wall thickness is similar to that of glass joints so will expand/contract at the same rate and will retain a high vacuum seal. Use hollow stoppers for high vacuum operations.
