Abstract
Abstract An elongate vial of glass or other breakable material includes upper and lower portions which are separated by a weakened portion to facilitate breaking of the vial at the weakened portion. Flexible sleeves surround the upper and lower portions of the vial adjacent the weakened portion and cover the weakened portion. The sleeves are deformable across the break in the portions of the vial when the vial is broken to minimize injury to persons who come into contact with the broken vial and damage to a catheter which might be inserted into the vial. The deformed portion of the sleeve which remains on the lower portion of the vial defines an opening to permit access to the contents of the lower portion of the vial.
