Sharps container

A multifunctional container for safe storage of medical or laboratory sharps comprising:

• a first compartment and a second compartment and a flexible liquid impermeable partition therebetween,
• wherein said flexible liquid impermeable partition is sealed to the multifunctional container along an entire perimeter of the flexible liquid impermeable partition in a manner which prevents liquid transfer between the first compartment and the second compartment;
• said first compartment defines an internal storage space sized and configured to contain an initial quantity of one or more unused sharps, said initial quantity of one or more unused sharps selected from pen needles, hypodermic needles, and syringes with attached hypodermic needles being present within the first compartment at a first time,
• wherein the first compartment further comprises a first aperture which may be opened to remove one or more unused sharp;
• and
• said second compartment sized and configured to contain a quantity of used sharps substantially equal to the initial quantity of one or more unused sharps at a second time, said one or more used sharps selected from pen needles, hypodermic needles, and syringes with attached hypodermic needles,
• wherein the second compartment further comprises a second aperture which has associated therewith a one-way mechanism configured and adapted to convey a used sharp from the exterior of the multifunctional container irreversibly into the interior of the second compartment,
• wherein the flexible liquid impermeable partition is configured and adapted to flex or deform from a first position to a second position such that a volumetric ratio between the internal storage space and the unused pen needle or syringe needle storage space may adjust as the ratio of the volume of contained used sharps to the volume of contained unused sharps changes.
