<p>PURPOSE:To obtain the container for medical treatments which has high transparency, good air removability and is free from blocking by using the container body which is formed by inflation molding of a specific resin and the inside surface of which has specific surface roughness and the constituting wall of which has specific transparency. CONSTITUTION:This container for medical treatments consists of the container body, the surface roughness of the inside surface of which is in a 1 to 3mum RZ (DIN 10 points average roughness) range. The transparency of the wall constituting the container body (in accordance with the method for testing plastic containers for liquid transportation specified in the general testing methods of the Japanese pharmascopoeia of the 10th revision) is >=80%. The container body is formed by inflation molding using an ethylene/vinyl acetate copolymer (EVA) or polyvinyl chloride(PVC). Since the container body has such surface roughness, the blocking of the inside surface does not arise and the foreign matter in the container body is easily discoverable. Further, the air is prevented from forming fine bubbles and sticking to the inside surface of the container body at the time of an air venting operation and, therefore, the air venting is improved.</p> |
