Due to intensive research and continuous development, Adolf Rambold not only invented the double chamber tea bag, which revolutionized consumer habits worldwide as a convenience solution since 1949, but also realized the first machine that enabled the production of double chamber tea bags on an industrial scale: the CONSTANTA.

CONSTANTA is considered the pioneer of modern tea culture. It was already capable of producing an impressive total of 120 double chamber tea bags per minute. In the end, continuous development enabled it to produce up to 180 tea bags per minute. With its two variants, CONSTANTA offered the production of naked tea bags as well as paper enveloped bags with cut-out tags. Since the 1950s, TEEPACK's CONSTANTA has been sold over 2000 times in over 50 countries.

The opportunity of machine production turned out to be a trend-setter, so that world markets adopted the principle of the double chamber tea bag. As a result, the demand for the double chamber tea bag expanded across the globe and tea consumption increased steadily. Nowadays tea is the most popular and most consumed drink in the world after water.

For the double chamber tea bag machine, which was further developed since 1991 under the names COMPACTA and PERFECTA in modular design, a worldwide demand arose and TEEPACK plays a leading role on the world market as an innovative specialist for efficient machines. Since the year 2011 COMPACTA complements the product portfolio of TEEPACK.

Today TEEPACK supplies its international customers with modular tea bag packaging machines which can be extended, configured and used according to individual needs. TEEPACK machines convince with efficiency, reliability and longevity – CONSTANTA is proving this every day. Some CONSTANTA machines with single-digit serial numbers are still in use today. One of the first machines, still functioning today, is located in front of the TEEPACK headquarters in Meerbusch.
