Abstract

The invention relates to a method for producing a closure in a container made of plastic in the blow-fill-seal method, in which method, in order to provide the container wall for the extraction process, preferably forming the piercing point, in the area of ​​the container wall Form a non-detachable connection with a sealing material composed of a joinable plastic, such as a thermoplastic elastomer, and carry out a joining process in which the joining pair is heated to a joining temperature significantly lower than its welding temperature, and for the material Locking engagement with slowly increasing pressure to press the engagement couple against each other, characterized in that the engagement process between the sealing material and the flexible membrane forming the extraction region of the container wall is carried out as follows, that is, after autoclaving During the autoclaving process, the mating couples are heated slowly, and the internal pressure of the container acting on the membrane during the autoclaving process generates a joining compression pressure that presses the mating couples against each other and at the same time reduces the pressure on the closure cap and the end. The number of bacteria in the space between the walls.

Description

technical field

[0001] The invention relates to a method for producing a closure in a filled and closed container made of plastic in a blow-molding method, in which method, for the arrangement of the container wall for the extraction process, A non-detachable connection is preferably formed between the area forming the penetration site and a sealing material made of heat-bondable plastic (such as thermoplastic elastomer (TPE)), the following joining process is carried out, that is, the jointing couple is inserted into it. For slow heating to a joining temperature between 100° C. and 140° C. and for a material-locked joint, the joining partners are pressed against each other with slowly increasing pressure and a marked reduction in the bacterial count occurs. Furthermore, the invention relates to a container having a closure produced according to the method. Background technique
