Straw cups are great alternatives to sippy cups, with a soft straw helping to develop sipping skills. The soft, silicone straw is easy to drink through and little ones don’t have to tip the cup up very far to drink from it. Featuring INTELLIVALVE™, a unique anti-leak technology which guarantees this weighted straw trainer cup is completely leak-proof as it withstands internal pressure meaning the cup won’t leak even when it is turned upside down or shaken. Our unique valve both seals and regulates the flow of liquid to stop leaks and to ensure easy drinking. With hygiene at the forefront of everyone’s minds our cups add an extra layer of reassurance as the drinking straw contains BACSHIELD™ antimicrobial technology. BACSHIELD™ is a commonly used silver-ion technology that provides antimicrobial product protection against unwanted microbes, recognized for centuries with no harmful effects. It works by preventing the growth of unwanted microbes that can cause product degradation, discoloration, staining or odor. This is achieved with silver ions mixed in the material in the straw*, preventing microbes from multiplying.All our products are BPA, BPS, PVC, Phthalate and Nitrosamine free.*The antimicrobial technology does not protect the user or others against disease causing organisms. The technology is not a substitute for good hygiene and/or cleaning practicesIndependent laboratory testing demonstrated a 99.9% reduction in microbes after 24 hours. BACSHIELD™ is tested to ISO 22196:2011 standards.
