BlenderBottles are cups used to mix beverages and foods such as protein shakes, puddings, sauces and eggs. The patented wire ball in the bottle is supposed to remove the clumps in protein shakes by mimicking the cyclone action of standard blenders.
BlenderBottles are manufactured by the BlenderBottle Company in Utah. Released on the market in 2004, they are available in an assortment of colors and sizes from 20 to 32 ounces. The bottles boast leak-resistant sealing and BPA free plastic. As of February 2015, the official BlenderBottle website claims that the bottles are the highest-selling type of shaker cup. The company even offers a private label option for corporate events.
The BlenderBottle Company also produces a diverse range of sports cups, storage containers and accessories geared toward athletes. The cups include the BlenderBottle ProStak, which adds a protein powder holder on the bottom of the bottle, the SportMixer, which adds the wire ball to a water bottle and the GoStak, a group of stackable storage cups. BlenderBottle accessories include backpacks, T-shirts, key-ring clamps and gym bags. There is even a recipe book for those looking to get more use out of the bottles.
