Being environmental friendly has become very common today and reduce waste and trash is also a primary responsibility of every earth citizen. For example, many laundry detergent manufacturers offer refill pack so that the detergent container can be reused
and thus reduce the amount of trash. However, many refill packs today are designed that close attention has to be paid when
performing the refill. But after my adjustment and design, the problem can be easily solved. By changing the refill pack from the
rectangle shape to cone shape, the refilling process be come much more convenient.
