A ball-shaped cap makes a square bottle easier to remember
Most shampoo bottles use pumps, flip-top caps, or standard screw caps. These closures are familiar and practical, but they can also make products from different brands look very similar.
The design in this case utilizes a round cap with a square container, thus instantly creating an impression.




Therefore, custom square shampoo bottles enables the support of multiple SKUs, no need to design new bottles for each SKU. The brands can adjust the bottle color, product text, and surface finish.

Packaging Solution: creating a recognizable hair care line
The following packaging concept shows how the custom square shampoo bottle can be used across a three-product hair care range
The products consist of a daily shampoo, a daily conditioner, and a product for scalp treatment. The challenge is for the products to look similar but at the same time be easily distinguished by customers.
In order to accomplish these, the following questions should be considered:
1. How to make the bottle of the product different from a regular shampoo bottle?
2. In what way can the three products share a unified image?
3. How to ensure easy product identification for customers?
4. How can color help achieve youthful and organic look?
5. How to sustain the possibility of using similar packaging for future products?
OUR SUGGESTION
Our suggestion for packaging
The three products will share the same 270 ml HDPE square bottle and off-white ball-shaped cap, while different colors will differentiate them.

DAILY SHAMPOO
BRIGHT GREEN BOTTLE · OFF-WHITE BALL CAP

DAILY CONDITIONER
LIGHT PINK BOTTLE · OFF-WHITE BALL CAP

SCALP TREATMENT
WARM YELLOW BOTTLE · OFF-WHITE BALL CAP
The daily shampoo will be packed in a bright green bottle, while the daily conditioner will come in a light pink one and the product for scalp treatment will have a warm yellow bottle. The shape and the color would remain similar throughout the replacement.
The color would make it easier for customers to tell one product from another, while the identical caps underline their belonging to the same line. One bottle can be used for all products without developing a new design for every SKU, which would make it possible to expand the line simply by changing the color and the text on the bottle.

WHY IT WORKS
Two practical benefits of this approach
The first benefit is consistency.
Each product has the same square bottle, ball-shaped cap, and arrangement. Even though the bottle colors differ, all three bottles appear to belong to one line of products. Each product can be identified separately, but the set of products looks unified.
The second benefit is simplified product identification.
The shampoo, conditioner, and scalp care product can be easily differentiated because of the different colors of the bottles-green, pink, and yellow. Customers will not have to search for the proper product among all available variants on the bottle.
The result of the packaging design
The final packaging solution kept the consistency of the line without making all bottles identical.
The matching ball-shaped caps construct the connection between the three products. Each product could be identified well thanks to the colors of the bottles.
The colors are calm and not very bright. Together with the color of the caps, they give the line a youthful and relaxed aspect that is suitable for everyday hair care products.
The ball-shaped cap presents a product as an individual item, but it still can be easily identified when reflects in the group of bottles.
As a group, the colored bottles make the range more attractive while the matching caps provide the link among them. Customers do not have any difficulties to tell a product from another one while maintaining the notion that they belong to one family.
If the company will introduce a hair mask or other treatment, it will be enough to select another color for the bottle, and use the same color for the cap.
Adapting the idea for different brands
The same packaging design may not necessarily have to use green, pink, or yellow colors. The companies may choose colors of the bottles depending on their marketing strategies, formulas, fragrances, or product types.

A professional hair care company may choose dark blue, dark grey, or black.

A botanical brand may use brown, beige, or muted green.

More a trendy brand may operate with pink, yellow, green, or blue colors.

A minimalist brand may use various tones of the same colors, which proves the simplicity of the line while making it easy to distinguish its items.
The rule is simple: every brand may use various colors of the bottles to differentiate products but stick to one common cap design.
