PRE-FILLED DISPOSABLE PIPETTES

摘要

A pre-filled disposable pipette body (40) for pharmaceutical and cosmetic products. The body consists of a hollow, rigid bulb section (44) forming a reservoir for storage and dispersion of the liquid (48) pharmaceutical or cosmetic product which is pre-filled within the body (40). The body (40) further includes a hollow tubular section (46) that is smaller in diameter and contiguous with the bulb section (44). The preferred embodiment has a hollow, frangible upper tube (42), with a distal end that is sealed for introducing air into the body (40) when the seal is broken, thus releasing the liquid (48) from the tubular section (46). The second embodiment has a resilient bulb section (44) and omits the upper tube. A tapered section (90) is added to the tubular section (46), with a hollow tip (86) on the end. A seal is in contact with the hollow tubular section, or tip, for retaining the liquid within the body and storage, consisting of either a liquid seal (58) or a resilient cap (50).
