Close bottles permanently or temporarily

Closing bottles serves two purposes. Either the contents should be sealed permanently and airtight, as with new bottles, or a flexible and reopenable use cap protects the contents of the bottle. The physical properties of the bottle content must be taken into account.

Mechanisms and lock types

Different bottle contents and shapes bring with them closure systems, which are often retained in the subsequent use closure. An alternative closure is required for single-use closure forms such as crown corks. The following types of permanent bottle closures are available:

  • Also read - Permanently and decoratively label bottles
  • Also Read - Opening a Bottle with Another Bottle
  • Also read - some or all of the bottles are covered with stickers
  • Twist lock with flat thread
  • Twist lock with deep thread (screwdriver or roll-on lock)
  • Rotatable crown cap
  • Pressed crown cap / beer capsule
  • Real cork (stopper)
  • Plastic corks
  • Clip locks

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

Lever locks

The leverage is created by a wire clip and is similar to the clip closures that are firmly attached to bottles. With head-closing models, the lever tilts when turned at right angles. As a result, he "pulls " an elastic plastic plug vertically in width. In the alternative variant, the clamping force is caused by a wire clip hooked on both sides, which presses the closure head onto the bottle opening.

Spring lock

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

Locking cone

Typical wine bottle stoppers and reusable cork stoppers can be referred to as closure cones. They are inserted into the neck of the bottle with adequate force so that they jam. In the case of metal versions, the dead weight stabilizes the position. With it, wine bottles can be closed again without corks.

Methods and Uses

When a bottle with a crown cap is opened, the closure usually bends. A crown cap or is designed as a single-use closure.

Twist locks made of aluminum and plastic can be used several times if handled carefully. However, the thread path must have at least two full turns in order to achieve airtightness.

Bottle corks made of natural cork or plastic can, if undamaged, be used to close the opened bottle. Because the top is narrower, the upside-down cork will fit more easily. Corks with plastic lids are designed to be closed several times. Airtightness is achieved by sufficiently pressing in the cone.

Tips & Tricks If you close an open wine bottle, the remaining content of the oxygen that has penetrated will still take effect. Decanting into a smaller bottle reduces the taste-influencing oxidation.
