摘要： A laboratory test tube is formed between male and female mold elements by injection of molten plastic material. The female element has a bottom element formed by first and second alternating complementarily shaped wedges. At least the second wedges are able to move under the pressure of the molten plastic from a rest position to an operative position in order to form slits which allow air, but not molten plastic, to exit from the mold.

摘要： Plastic material is injected into a chamber defined between a female mold member and a male mold member, while air is evacuated from the chamber. In the evacuation step, the air contained in the forming chamber progressively exits from the mold under the pressure of the melted plastic material through a multiplicity of slits made on the female element at different heights along the above-mentioned central axis. The slits have dimensions such as to allow the passage of the air and at the same time to block the flow of the melted plastic material from the forming chamber.

摘要： Plastic test tube for taking blood samples, comprising a hollow tubular body and an adhesive protective film able to adhere to the tubular body. The tubular body is made of polyethylene terephthalate and has: a tubular wall which delimits a working volume and defines an outer surface; an open mouth for insertion of liquids at a first end of the wall; and a bottom for closing a second end of the wall. The adhesive protective film is able to adhere to the wall of the tubular body over at least a portion of the outer surface. The test tube is characterized in that the wall of the tubular body has a thickness in the range of 1 to 3 mm and in that the protective film is defined by a layer of polypropylene, polyethylene or copolymers thereof. The layer has a thickness in the range of between 40 and 60 μm and is able to form a liquid barrier.
