A two-chamber container for accommodating flowable substances separately from one another has an upper chamber and a lower chamber, a reduced diameter bottle which separates the chambers from one another and is provided with a plug in a plane of the reduced diameter, a rotary cap provided with a plunger and turnable so that the plunger is pressed from the plane of the reduced diameter into the lower chamber so as to bring both substances together. The rotary cap has a thread in the upper chamber, while the plunger has a threaded portion engaged in the thread of the rotary cap. The plunger is formed as a tubular plunger which has a first end and a second end formed so that in a base position the first end of the plunger is connected with the threaded portion of the plunger in fluid-tight manner and the second end of the plunger extends through the plug into the lower chamber, and the plunger is connected with the plug in fluid-tight manner.

An apparatus for wrapping flexible elongate objects has a wrapping wheel arranged coaxially to a longitudinal axis of the objects and having a tape spool support movable therewith, drive mechanism with a roller drive for advancing the objects and arranged at one side of the wrapping wheel, and an electric program control for controlling a drive length by set point/control point comparison. The drive mechanism also includes a carriage movable parallel to an axis of rotation of the wrapping wheel and to the longitudinal axis of the objects, and includes a holding device on the wrapping wheel side for holding an end of an object for pulling the object through the wrapping wheel. The drive mechanism also includes two vertically displaceable rolls which for a start of the wrapping are positioned relative to one another so far that the holding device is movable between the rolls to the wrapping wheels. The rolls are arranged vertically one above the other and oriented with their axes of rotation transversely relative to the longitudinal axis of the objects. One roll functions as a length data detector and the other roll functions as a drive, the carriage is synchronized at least in part with the drive so that for wrapping in the region of advancement of the carriage the holding device holds the end of an object, and for passing the region the rolls take over a further drive of the object and thereby the holding device opens for releasing the end of the object.
