ABSTRACT:
This invention relates to a medical device having a plastic cylinder that is uniquely decorated. More particularly, this invention relates to an improved scale on a plastic syringe containing protruding volume measuring scale marks and indicia. These protrusions provide tactile sensation of the scale and slip-resistant holding of the syringe barrel. Both the plastic syringe barrel and scale can be formed separately, and then attached to each other. Methods of apply the scale in this manner include overmolding, and heat welding. The plastic syringe and improved scale can also be formed simultaneously using co-injection molding methods. Advantages of forming a scale on the plastic syringe using any of the techniques described above includes eliminating secondary operations such as printing, and permanently and accurately positioning the scale. Different thermoplastic and elastomeric materials and colors can also be used to form the scale. Another advantage is that the scale can be formed to 360.degree. around the cylindrically-shaped plastic syringe barrel. Traditional printing methods like gravure printing are currently unable to achieve this feature.
