Abstract
A pre-filled disposable pipette () consisting of a hollow bulb () dimensioned to enclose a medicinal product. From a lower end () of the bulb () is attached sequentially a medicinal transfer tube () and a medication fill tube (), from where the medicinal product is applied. Between a lower end () of the tube () and an upper end () of the tube () is formed a break-away notch (). When the tube () or the tube () is rotated, the notch () is twisted and breaks-off, thus allowing the medicinal product to flow from the bulb () and be released from the tube (). The pipette () includes a primary grasping tab () attached to an upper end () of the bulb (); a secondary grasping tab () attached to each side of the tube (); and a support tab () attached to each side of the tube (). The invention also discloses several methods for sealing the lower tip () of the medication fill tube ().
