For half a century, the "knick-pack" has shaped how chocolate lovers open their bars. This packaging innovation from Ritter Sport, introduced in the summer of 1976, has become an iconic feature that goes far beyond mere functionality. The simple act of bending to open the bar has become an integral part of the product experience.
The square shape of Ritter Sport chocolate, conceived by Clara Ritter back in 1932, found its perfect packaging in the 1970s with the „Knick-Pack“. This era was characterised by increasing mobility and a need for practical solutions. The Knick-Pack met these demands precisely and was advertised with the slogan "Der Trick mit dem Knick und die Masche mit der Tasche" (The trick with the fold and the cleverness with the pouch), referring to the resealable pouch that makes the chocolate ideal for on-the-go.
Focus on sustainability
While the design of the break-apart bar packaging has only been minimally modified over the years, the material has fundamentally changed. Originally made from a non-recyclable composite material, Ritter Sport has been using a recyclable single-material film made of polypropylene since 1991. This change allows the packaging to be kept in circulation as recyclable material without compromising product protection. In the long term, however, Ritter Sport aims to develop packaging made from renewable raw materials, even though initial tests with paper-based materials have not yet been successful due to product-specific requirements.
Challenges and Innovations
The variety of Ritter Sport flavours presents particular challenges for packaging. For example, some flavours are unsuitable for paper-based packaging due to their ingredients. For instance, the raisins in Rum Raisin Nut are too moist and the cornflakes in Crunchy Cornflakes have edges that are too sharp. However, according to the company, it remains committed to finding solutions that ensure both the protection and sustainability of the packaging.
