Abstract: The present invention relates to improvements in conventional protection barrel and cap packagings for hypodermic needles, whereby a structural guard is provided to encourage a user's fingers to locate directly behind the guard, and around the outer surface of an opening into the protected barrel. A person inserting a needle into a barrel automatically seeks to grasp the barrel proximate its open end, to avoid yawing of the barrel during the manipulative process. The present invention facilitates holding of a barrel proximate the opening, while providing, as an extension therefrom, a needle entrance guide means which extends axially and laterally therefrom. The laterally expanded barrel opening defines a transition ramp surface into the barrel open end.

Abstract: A secure specimen collection vessel is provided, which in a preferred embodiment comprises a four-chamber base cup, 1, a twist-lock antirotation cap, 2, and a resilient sealing plug, 3. Clip-off drain tabs, 6, and vent tabs, 7, are located at the bottom end of the base cup, allowing each chamber to be drained individually for repeat analysis of a urine sample. The locking, antirotation cap, 2, prevents the contents of the vessel from being accidentally contaminated by the external environment, and also assures that any attempt to forceably remove the cap, 2, will result in visibly obvious damage to the collection vessel.
