What is sippy cup? How to use in English

The term "sippy cup" is commonly used to refer to a type of spill-proof drinking cup that is particularly popular among young children. The origins of this word can be traced back to the 1980s, when a company called Playtex introduced a new product known as the "Anti-Spill Training Cup." This cup featured a unique seal around the rim that prevented spills and made it easy for toddlers to learn to drink independently. At first, the cup was marketed under the name "Anti-Spill Training Cup," but as the product gained popularity among parents, other companies began to produce their own versions. To differentiate their cups from the original Playtex design, these companies came up with their own names for the product, such as "Spill Proof Cup" or "Spill Protector Cup." However, one company in particular – a North Carolina-based manufacturer called WEOP – coined the now-famous term "sippy cup." The company's product, called the "Sippy Cup," quickly caught on with parents and became something of a household name. The exact origin of the term "sippy cup" is somewhat unclear. Some people speculate that it comes from the way young children "sip" from the cup's spout, while others believe it's a combination of "sip" and "cupy" (as in cup for a toddler). Regardless of its origins, "sippy cup" has become an integral part of our everyday language, and is a term that most parents can readily understand and appreciate.
