Tamper-Evident Closures

Tamper-evident closures by Farmmash provide visible evidence of the first opening of a pharmaceutical package. They help users identify whether a bottle has already been opened.

The range includes several screw-cap designs for different bottle neck formats. In addition, selected models combine first-opening control with a child-resistant mechanism.

Tamper-Evident Solutions for Pharmaceutical Bottles

Farmmash offers closures for different pharmaceutical packaging requirements. Available models include solutions for GL18/DIN168 and Ø28 mm bottle neck formats.

The first-opening feature usually works through a tamper-evident ring or another dedicated element. When the package opens for the first time, this element changes or separates. As a result, the user receives a visible indication of opening.

Different models provide different sealing and functional options. Therefore, the closure should always be selected together with the intended bottle.

Tamper-Evident and Child-Resistant Functions

Some pharmaceutical products require more than first-opening control. For these applications, selected Farmmash closures combine a tamper-evident feature with a child-resistant opening mechanism.

The two functions serve different purposes. First-opening control shows whether the package has previously been opened. In contrast, the CRC mechanism helps reduce unintended opening by young children.

Therefore, the required closure design depends on the product and packaging specification.

Bottle Neck Compatibility

Closure performance depends on accurate interaction with the bottle neck. Thread geometry, neck dimensions and sealing surfaces all influence the final result.

Farmmash supplies models for common pharmaceutical formats, including GL18/DIN168 and PP28-related applications. However, compatibility must always be confirmed with the actual bottle.

In addition, some models can work with compatible dosing components. These may include droppers, dosing inserts or other packaging elements.

Selection and Testing

Tamper-evident closures should be evaluated as part of the complete packaging system. The bottle, closure and product can all affect performance.

For this reason, Farmmash can provide technical information for available models. Customers can also request samples for their own compatibility and functional tests.

Testing before serial production helps confirm sealing, opening performance and first-opening indication.
