      Connected caps: Tethered caps

      To ensure that the caps on beverage containers of PET no longer get lost so easily and end up as waste in the environment, and as of 2024, in the EU, they will have to remain connected (tethered) to the packaging once opened. 

      Basically, at tethered caps, a distinction must be made between hinged caps and screw caps: 

      • Hinged caps – also known as flip lids, flip tops and thumb-ups – have a design which keeps them permanently connected to the bottle right from the outset. 
      • With screw caps, on the other hand, the connection between container and cap must be realised by an additional feature. 

      Krones offers just the right sorting and capping technology for every variant.

      "Tethered" stands for connected: In conjunction with caps, this means that they remain connected to the bottle even after opening.

      The portfolio

        Field of applications Output range

      Screw capper for plastic caps

      Modulcap CM*

       

      * C = Chucks(cap retainers), M = mechanical

      Single-threaded and multi-threaded caps**:
      • Flat caps ranging in size from 26 - 43 mm
      • Rotationally symmetric sports caps
      • Tethered caps
      Up to 84,000 containers/h (depending on the cap type)

      Screw capper for plastic caps

      Modulcap CS*

       

      * C = Chucks(cap retainers), S = servomotor

      Single-threaded and multi-threaded caps**:
      • Flat caps ranging in size from 26 - 43 mm
      • Rotationally symmetric sports caps
      • Press-on caps
      • Tethered caps
      Up to 84,000 containers per hour

      Screw capper for plastic caps

      Modulcap GS*

      * G = Grippers, S = servomotor

      With the servo-driven screw capper for plastic caps, there is also an optional variant with gripper in addition to the one with cap retainer: This way, non-rotationally symmetric caps such as caps with flaps or recessed grips can be processed as well. Tethered caps can also be processed with the Modulcap GS.

      Apart from this special feature, this machine type is similar to the Modulcap CS in terms of design and mode of operation.

      Up to 84,000 containers per hour

      • Crowns
      • Twist-off caps
      • Ring-pull caps
      Between 10,000 and 120,900 bottles per hour
      Aluminium Roll-On Capper
      • Pilfer-proof and Stelcap caps
      • Sizes: 28 mm and 31.5 mm
      Between 10,000 and 60,000 bottles per hour

      Benefits

      Modulcap CM screw capper for plastic caps

      Caps are fitted perfectly

      Use of a hysteresis clutch ensures screw caps are applied at a constant force.

      Can be optimally cleaned

      The capping heads can be cleaned perfectly with hot water or foam.

      Modulcap CS and Modulcap GS screw capper for plastic caps

      Hygienically optimised design

      The drives are positioned to reliably prevent germs from being spread into bottles while they are still open.

      Caps are fitted perfectly

      The servo controller for the capping process precisely monitors the application torque. This ensures that roll-on caps are applied at a constant force.

      Reliable cap feed

      The caps are hygienically conveyed to the pick station.

      Can be optimally cleaned

      The machine can be cleaned very effectively with foam and spray disinfection. The open design of the pick station and cap retainer ensures that individual parts are readily accessible.

      Easy maintenance

      All component groups have a lubrication-free and maintenance-free design

      Modulcrown crowner

      Precision

      Crowns enter the line with a defined alignment and are precisely positioned on the transfer plate by a draw-in magnet.

      Designed for practical applications

      Bottle-neck centring ensures that even bottles with inaccurate dimensions are reliable sealed.

      Hygiene

      Numerous refinements and optional equipment on the agitator, feed chute, top part and capping heads themselves deliver a major hygiene boost during production.

      Suitability for retrofitting

      Numerous new features can also be retrofitted to existing crowners from Krones.

      Aluminium Roll-On Capper

      Flexibility

      The thread and tuck-under roller arms can be quickly adjusted to the plunger dimension.

      Can be optimally cleaned

      The capping heads can be cleaned perfectly with hot water or foam.

      Retains its value

      The stainless steel design of the roll-on capper is highly resistant to cleaning agents and disinfectants.
