Seal bottles permanently or temporarily


Closing bottles fulfills two tasks. Either the contents should be sealed permanently and airtight, as with new bottles, or a flexible and re-usable closure protects the bottle contents. The physical properties of the bottle contents must be taken into account.

Tuners and types of locks

Different bottle contents and shapes bring closure systems, which are often retained in the subsequent use closure. For one-time closure forms such as crown corks, an alternative closure is required. The following permanent bottle cap types are available:

  • Screw cap with flat thread
  • Screw cap with deep thread (screwdriver or roller shutter)
  • Rotatable crown cork
  • Pressed crown cork / beer capsule
  • Genuine corks (stoppers)
  • Plastic corks (plugs)
  • latches

To close an opened bottle or cover a utility bottle with non-perishable contents, the following closure methods are available:

lever locks

The leverage is created by a wire hanger and is similar to the firmly attached to bottle buckles. In the case of head-closing models, the lever tilts in a right-angled flip. As a result, he "pulls" an elastic Kunststoffpfropfen vertically in the width. In the alternative variants, the clamping force is caused by a hooking hook on both sides, which presses the closure head on the bottle opening.

spring Clip

The champagne bottle stopper is known. The cylinder cap has a spring-loaded shutter disc inside. The spring closure is pressed onto the bottle opening and fixed by two foldable closure wings.

closure cone

As a closure cone typical wine bottle caps and reusable cork stoppers can be called. They are inserted into the neck of the bottle with adequate force, causing them to jam. For metal versions, the dead weight stabilizes the situation. With it, wine bottles without corks can be closed again.

Methods and uses

If a bottle with a crown cap is opened, the closure will normally bend. A crown cork or is designed as a single closure.

Turn-locks made of aluminum and plastic can be used several times with gentle handling. However, the thread path must have at least two full turns to achieve airtightness.

Bottle corks made of natural cork or plastic, if undamaged, can be used to close the opened bottle. Since the upper side is narrower, the inverted cork fits easier. Corks with plastic lids are designed for multiple closure. Airtightness is achieved by sufficient depression of the cone.

Tips & Tricks

If you close an opened wine bottle, the residual contents of the infiltrated oxygen still work. Transferring to a smaller bottle reduces the taste-affecting oxidation.
