CONTAINER FOR HANDLING AND TRANSPORTING OF HIGH-PURITY AND ULTRA-HIGH-PURITY CHEMICALS

摘要

The invention relates to an empty container (1) for accommodating high-purity and ultra-high-purity, air- and/or moisture-sensitive liquid or condensable compounds, comprising a cylindrical jacket (3), a bottom (4a) and an upper end piece (4b, 4b′) at the two ends of the cylindrical jacket, an associated connection unit (2) including shut-off/multiple-way and rinsing system (5), and an associated immersion pipe (7), characterized in that the lower end of the immersion pipe (7a) protrudes into a recess (4c) (depression), which is introduced in the bottom (4a) and which is the lowest point of the bottom, and/or the lower end of the immersion pipe (7a) is tapered and is brought close to the lowest point of the bottom (4a) to within less than 2 mm by means of the tip of the tapered immersion pipe (7b) or touches the lowest point of the bottom with the tip of the tapered immersion pipe (7b). The invention further relates to the use of empty containers according to the invention for storing, handling, and/or transporting such high-purity and ultra-high-purity compounds.

主权项

1. A container comprising
a cylindrical wall and, at the two ends of the cylindrical wall, a bottom and an upper closure, and an associated connection unit which comprises a shut-off/multiway and flushing system and associated immersed tube, wherein a lower end of the immersed tube is cut at an angle, and a tip of the immersed tube cut at an angle comes to within less than 2 mm of the lowest point of the bottom or the tip of the immersed tube cut at an angle contacts this point, or the lower end of the immersed tube projects into a depression made in the bottom and is the lowest point of the bottom and the lower end of the immersed tube comes to within less than 2 mm, of the lowest point of the bottom or the lower end of the immersed tube projects into a depression made in the bottom and represents the lowest point of the bottom and the lower end of the immersed tube is cut at an angle, and the tip of the immersed tube cut at an angle comes to within less than 2 mm of the lowest point at the bottom or the tip of the immersed tube cut at an angle contacts this point.
