Corpo (40) de tubo descartável de laboratório, pré-enchido, para produtos farmacêuticos e cosméticos. O corpo consiste de parte oca e rígida em forma de bulbo (44) que forma reservatório para acondicionamento e liberação de produto líquido (48) farmacêutico ou cosmético que é pré-enchido dentro do corpo (40). Adicionalmente, o corpo (40) inclui parte tubular oca (46) que é de diâmetro menor e próxima da parte em forma de bulbo (44). A versão principal possui tubo (42) superior oco, com extremidade distante que é lacrada para introdução de ar dentro do corpo (40) quando o lacre é rompido, desta forma liberando o líquido (48) da parte tubular (46). Uma segunda versão tem parte elástica em forma de bulbo (44), eliminando o tubo superior. à parte tubular (46) é adicionada parte afunilada (90) com ponta oca (86) na extremidade. Em contato com a parte tubular oca fica um lacre, ou em contato com uma ponta, para que o líquido seja retido e armazenado dentro do corpo, consistindo o lacre de algum líquido (58) ou tampa elástica (50). A pre-filled disposable pipette for pharmaceutical and cosmetic products which has a hollow, round pipette body (40). The body consists of a hollow, rigid bulb section (44) forming a reservoir for storage and dispersion of the liquid pharmaceutical or cosmetic product which is pre-filled within the body. The body (40) further includes a hollow tubular section (46) that is smaller in diameter and contiguous with the bulb section, for ease of handling the pipette. 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 from the tubular section. The liquid is dispensed from the body by breaking the upper tube allowing air to enter the pipette with the liquid flowing by gravity. The second embodiment has a resilient bulb section and omits the upper tube. A tapered section (90) is added to the tubular section, with a hollow tip (86) on the end. The liquid is dispensed from the body (40) by squeezing the bulb. 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).
