Abstract A safety vial and cap therefor, preferably of resilient plastic material, designed to prevent the inadvertent opening and usage of stored medicines by, for example, young children. The cap has a radially outward projecting cammed locking surface over a portion of its radius, the cap being substantially of a plug type. The cap further has an additional outwardly extending locking lug portion of small angular dimension opposed to the aforementioned outwardly projecting cammed surface. The top of the vial includes an inwardly projecting ribbed section extending around the inner circumference thereof, with a slotted opening therein of substantially the same dimension as the second outwardly projecting locking member of the plug-in cap. Once the cap is inserted into the vial it is necessary to bring the second outwardly projecting locking lug into registry with the slot in the top rib of the vial to permit upward movement of the cap through the slot therein. This will, in addition to locking the cap on the vial to prevent inadvertent opening thereof, further require that the cap be moved into exact registry to permit desired opening. Furthermore, once the cap is inserted onto the vial, except for the slightly extended tab, there are no projections outside the circumference of the cap which would make it possible for someone to forcibly remove the cap from the vial.
A safety vial and cap therefor, comprising in combination: a hollow container having generally uniform wall thickness, the top of said container being open and including an inner depending rim shaped portion of a given depth around the inner diameter thereof, said inner depending rim shaped portion having a slot therein; a plug type cap comprising an upper portion having a diameter approximately equal to the outer diameter of said container and a lower portion depending from said top portion and having an outer diameter approximately equal to the inner diameter of the inner depending rim shaped portion of said container, further including a first protuberance on the outside of the lower portion of said plug type cap, said first protuberance having a dimension equal to or less than the dimension of the slot in said inner depending rim shaped portion of said container, and a second protuberance on the lower portion of said plug type cap, oppositely disposed with respect to said first protuberance and having a dimension greater than the dimension of the slot in said inner depending rim shaped portion of said container.
