We are a new venture specializing in the creation of dual sided hair care products. Our first product is a double sided shampoo-conditioner bottle. The product is eco-friendly and saves money and space compared to buying separate bottles of shampoo and conditioner.

We are looking for a concept/prototype design in 3D. We have attached a product design sketch and photos describing the two sided bottle and twist caps.
We want a 12 oz. cylinder shaped bottle with a slight hour glass shaped design. The Shampoo portion of the bottle will be separated by the Conditioner portion of the bottle by a hidden plastic disc in the interior. The shampoo portion of the bottle will be a royal blue gradient - darker at the top and becoming lighter towards the middle. The conditioner portion of the bottle will be a grass green gradient - darker at the top and becoming lighter towards the middle. OR, WHATEVER COLOR and STYLE LOOKS BEST. The caps on both sides will twist. When you twist the cap, a small hole in the middle opens up to pour out the product (see pictures). We want a printer ready file to create a product prototype. Any additional ideas and label design are encouraged. We are open to any and all ideas re: the best way to bring the product to life.
Don't Wants:
Un-manufacturable designs
No childish look
Hard plastic (needs to be somewhat pliant)
  1. Autocad and Rhino3D. And the 3D file must be in STL, or stereolithographic file format, for printing

Hi, do you accept CATIA cad file?

Thx Adam,

Based on what I have learned from you and others, the requirements will be somewhat different. We will create 2 bottles and connect them together at the middle, which addresses the internal disk and I will use a heat affixed label to address the color of the bottle.

Bottom line, even if design feasibility existed, packaging costs would be so high that market price would be out of reach. It would be like Willy Wonka trying to sell chocolate bars made in the section of the factory where the golden geese eggs were produced.

Additionally, even if the technology existed to blow mold a component with a dividing wall, the requirement for dual colors in a single or multiple cavity blow mold would be an additional challenge that is not currently available as a manufacturable possibility, let alone a "color fading" effect as what is being defined in the design scope.

As a long time designer in the plastics industry, you cannot manufacture what is being asked for. A blow molded bottle cannot have a "dividing" wall as what is being requested with current blow molding technologies (defined as a "dividing disc" in your design scope). While the idea is wonderful, it's not feasible with any design unless it's multiple blow molded bodies / injection molded components either mechanically joined together or otherwise, and at that point product packaging would out weigh marketplace competitiveness for a product of this type. If this was feasible, it would have been done long ago, and there would be numerous other packaging products on the market with similar design traits (e.g. laundry soap dispensers with detergent and fabric softener in a single packaging unit). Sorry to be the bearer of bad news.
