<p><P>PROBLEM TO BE SOLVED: To improve the strength of a sidewall part of a measuring container formed of a resin and prevent an instrument inserted into the measuring container from being caught on the inside of the sidewall part. <P>SOLUTION: This measuring container 1 acting as a medical beaker included in a disposable medical supply set is made such that a diameter of the upper end of a second inner side surface 1121 acting as an inner side surface of a lower step 112 of a sidewall 11 is made to be smaller than a diameter of the lower end of a first inner side surface 1111 acting as an inner side surface of an upper step 111, the lower end of the first inner side surface 111 and the upper end of the second inner side surface 1121 are connected by a connecting surface 1131 to cause a step to be formed on an inner side surface 1101 of the sidewall 11. With this arrangement, the sidewall 11 is provided with an enhanced strength against a side load. In the measuring container 1, the second inner side surface 1121 of the lower step 112 is made to have a substantial cylindrical surface and a protrusion protruded toward an axis J1 is not arranged on the second inner side surface 1121. As a result, an instrument inserted into the measuring container 1 is prevented from being caught on the inside of the sidewall 11. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
