FIELD: transportation, package. ^ SUBSTANCE: capping device for container with push-pull capping device includes device of sheet material puncture with axial symmetry, which can be inserted and displaced in axial direction into capping device separately from push-pull part. Device of sheet material puncture is integral and features sealing element with axial symmetry, located between driving end and puncturing end and ensuring sealing and fixating contact with capping device. Container capping device includes closing part which can be attached around container opening, and moving part shifting along closing part. Capping film to be punctured is attached to closing part so that an additional chamber isolated from container contents is formed in the internal space of closing part. Device of sheet material puncture is attached so as to shift along closing part. Capping film can be torn or punctured by activation of puncturing device. Configuration of additional chamber ensures complete isolation for containment of various substances. Device of sheet material puncture and moving part can shift along closing part separately from each other, and capping film is attached firmly to closing part. Device of sheet material puncture can be inserted into closing part to ensure sealing and fixation. ^ EFFECT: more simple manufacturing and assembly of capping device. ^ 8 cl, 8 dwg |
