Greiner Packaging, Holy debut syrup bottle with integrated five-level dosing system in the cap

GERMANY – Greiner Packaging has unveiled a syrup bottle with an integrated mechanical dosing system for drinks brand Holy, featuring five adjustable flavour intensity levels and interchangeable syrup pods in a reusable design.

The bottle is made of Tritan and the cap of ABS, along with functional silicone elements. Greiner Packaging says it further developed Holy’s bottle concept to industrial maturity. 

The drinking bottle and cap consist of 13 components, with the dosing mechanism based on extremely tight injection moulding tolerances including a central component with an opening of less than one millimetre. 

The bottle is dishwasher-safe up to 50°C and intended for long-term use.

Precision Engineering Meets User Experience

The liquid dosing is made possible by a mechanical system in the cap, with an integrated carrier using IML technology for interchangeable syrup pods. 

The five-level adjustable dosing allows consumers to dial flavour intensity up or down, transforming the drinking experience from passive consumption to active customisation.

Florian Horsch, Director of Product at Holy, explained that Greiner is far more than a traditional plastics specialist, noting that it is a place where people work with passion and genuine enthusiasm, and that these shared values laid the foundation for a successful project.

A Reusable System for Reduced Packaging

The new product line marks the first time Holy has used liquid concentrates for mixing instead of powder. 

The brand plans to gradually expand the new category and establish it as a permanent part of its portfolio. 

Combined with interchangeable syrup pods, the bottle forms a reusable system designed to reduce the need for single-use packaging, aligning with Greiner’s broader circular economy strategy focused on “Reduce, Reuse, Recycle” principles.

The development represents a shift in beverage packaging thinking. Instead of shipping pre-mixed drinks in single-use bottles, Holy and Greiner separate the liquid components, water is added by the user, while the flavour concentrate is delivered in a small, interchangeable pod. 

The bottle is the durable asset; the pod is the consumable. This decoupling reduces the weight and volume of shipped goods, lowers transport emissions, and keeps the primary packaging in use for years rather than minutes.

When the Cap Becomes the Interface

A bottle that doses flavour mechanically, without batteries or electronics, proves that sustainable packaging can also be high-tech. 

For beverage brands, the Greiner-Holy collaboration offers a template for shifting from disposable to durable: keep the bottle, replace the pod, and let the consumer dial in their taste.
