A TUBULAR CONTAINER PROVIDED AT ONE END WITH A FIRST CAP, WHICH HAS BOTH A SEALING FUNCTION AND A PLUNGER FUNCTION, AND AT THE OTHER END WITH A SECOND CAP WITH A SPOUT

摘要

A container (4) for a lubricant has a cap (31) for sealing of one end (50) of a cylindrical tube (2). The cap shows a bottom (32), from the periphery of which extends in axial direction a circumferential interior collar (36), which abuts the inside of said tube end and has a double function, namely apart from the sealing frunction a second function as plunger for feeding out the tube contents by means of e.g. a plunger rod of a pistol-like tool as known per se. To this purpose, the delimitation edge of the interior collar (36) which is turned away from the bottom connects to a bridge (39) located within a radial plane and leading to an exterior collar (40) which is concentric with the interior collar and surrounds said tube end together with the interior collar and the bridge. This cap is provided with a groove-like circumferential weakened part (38) permitting release of the bottom (32) during transition to plunger function. According to the invention said weakened part (38) is provided within or at said bridge (39) and are the sides of the collars and the tube which are facing each other provided with circumferential arresting and sealing grooves and bulges, respectively, acting upon the other part for at least temporaly positioning or retaining or sealing of the cap (31) in relation to the tube. Furthermore, the other tube end is sealed by a specially shaped cap which is provided with a spout (46), which latter cap co-operates with a likewise specially designed tube end.
