Klorin WC Gel is a redesign of the existing Klorin bottle by Lilleborg & Orkla foods. A team of designers and strategists from Orkla followed the project from initial brief to concept development and final reviews.

Droplet design language

The design motif consists of four droplets rotating around the bottle itself. We wanted the bottle to reflect the area of use, the toilet, and it’s flushing motion.

Pushing the boundaries for sleeve labeling

Stretching a heat shrinked sleeve over concave cuts creates new surface qualities and challenges the notion of what is suitable for use of sleeve labeling.

Integrating bottle design and branding

By designing for the use of sleeve labeling, one can easily adapt the design for different varieties and sub brands. Patterns, textures and other grpahical elements can interact with the underlying shape in several ways.

Sketching process of bottle design
Group sketching in two directions

Our sketch process involved two main explorations: A cylindrical silhouette and rotating lines. Combining these two features resulted in the final direction for our design.

According to Orkla, the customer purchase decision happens in front of the store shelf. By breaking the form conventions of the category, we are hoping to to capture the attention of the customer.

Designing for blow molding

As a central part was learning to design for traditional production processes, the use of PET plastic and blow moulding was a given constraint.

Analysis of current bottle design and market position
Gap between design and price segment

While current Klorin bottle has an industrial and strict design language, the product itself is in the top of the price segment. We wanted to explore how a more premium look could reflect both the price and quality.

Form analysis of market
Positioning design language in the market

By studying the design language of competing products, and placing them on a grid system, we identified unique design opportunities.

Parallel to exploring overall shapes, we made small material studies of heat shrinking sleeves. We discovered that while stretching the sleeve over gaps indeed creates pockets of air, it also leads to interesting tactile and surface qualities.

Exploring shrinking sleeves as a material

We felt that continuing in this direction could challenge the designers at Orkla as to what they considered suitable for shrink wrapping.

Client feedback on design direction

After presenting mood boards for three form directions, we were advised by the Orkla team to combine a simple design language with a flushing motif.

Iterating through clay models

Quick mock up models in clay were made to test the ergonomics and scale of our sketches. We simulated a heat shrinked sleeve bythreading a cut and tied stocking over the models. The final was chosen due to sensible proportions and fit in hand.

We explored different positions for the end capsule., seeing how it would relate to the rotating droplet motif. The chosen solution is both a nod to the original design, while also slimming and softening the proportions.

Adjusting cuts for sleeve interaction

We continued studying the material qualities of the sleeve material by removing the sleeves from empty bottles and reshrinking it over scale models. Adjusting the width and depth of the droplet cuts provided us with the dimensions and curvature for the desired surface qualities.

Due to studying the material throughout the process, we had no problems applying it to the final blow molded bottle.

“Sorry, but this bottle looks like something you would use to clean your toilet with and not drink from!”

Throughout the process, we faced the challenge of designing a unique and appealing bottle, whilst not looking like something you or even a child would like to drink from. Blind testing the bottle on people outside of school showed that we luckily avoided this concern.
