Tervis tumblers are renowned for their durability and insulation, making them a popular choice for keeping drinks at the desired temperature. But a common question arises: Can you safely put hot drinks in Tervis tumblers? The answer, while seemingly simple, requires a deeper dive into the materials, design, and potential limitations of these beloved beverage containers. Let’s explore everything you need to know.
Understanding Tervis Tumblers: Construction and Materials
To determine the suitability of Tervis tumblers for hot beverages, it’s crucial to understand their construction. Tervis tumblers are primarily made from BPA-free plastic, specifically a type of Eastman Tritan copolyester for the inner and outer shells. This material is known for its clarity, impact resistance, and temperature resistance. The key to Tervis’s insulating properties lies in its double-walled construction. This design creates an air gap between the inner and outer layers, reducing heat transfer through conduction and convection. This insulation helps to keep cold drinks cold and hot drinks hot for extended periods.
The lid is typically made of polypropylene, another type of BPA-free plastic that is also heat resistant. It’s important to note that while the materials themselves are generally safe for hot liquids, certain aspects of the design and usage can impact the overall suitability for hot drinks.
The Role of the Double-Walled Design in Temperature Regulation
The double-walled insulation is what sets Tervis tumblers apart. This space acts as a barrier, preventing the heat from a hot drink from quickly escaping to the outside, and preventing the cold from a cold drink from warming up too fast. The efficiency of this insulation depends on the integrity of the seal between the inner and outer walls.
The Official Stance: What Tervis Says About Hot Drinks
Tervis, the manufacturer, explicitly states that their tumblers are safe for both hot and cold beverages. Their website and product information often highlight the tumbler’s ability to keep drinks at the desired temperature, whether it’s a steaming cup of coffee or an icy smoothie. However, there are nuances to this statement.
Tervis recommends caution when using their tumblers with very hot liquids. While the tumbler itself can withstand high temperatures, there’s a potential risk of scalding from the hot liquid itself, especially if the lid is not properly secured. They suggest allowing extremely hot beverages to cool slightly before pouring them into the tumbler.
Specific Temperature Recommendations and Guidelines
While Tervis doesn’t provide a specific maximum temperature rating, it’s generally advisable to avoid pouring boiling liquids directly into the tumbler. Allowing beverages to cool slightly before transferring them can minimize the risk of warping or damage to the plastic, and also reduces the risk of burns. A temperature range of below boiling (around 180-190°F or 82-88°C) is generally considered safe.
Potential Concerns and Limitations with Hot Drinks in Tervis Tumblers
Despite Tervis’s claim of suitability for hot drinks, certain concerns and limitations should be considered. While the materials are generally heat-resistant, extreme temperatures over prolonged periods could potentially weaken the plastic or compromise the seal between the inner and outer walls.
The Risk of Warping or Damage from Extreme Heat
Repeated exposure to very hot liquids can, in rare cases, cause the plastic to warp or become brittle over time. This is more likely to occur if the tumbler is subjected to extreme temperature fluctuations, such as going directly from a hot dishwasher to being filled with a boiling liquid.
Lid Considerations and Potential Issues
The lid design is another factor to consider. While Tervis lids are designed to be secure, they are not completely leak-proof. With hot liquids, the steam pressure can potentially cause the lid to pop open or leak, especially if the tumbler is overfilled or tilted. It’s advisable to use caution when handling tumblers filled with hot liquids, and to ensure the lid is properly secured. Tervis offers a variety of lids, some of which are designed for better spill resistance.
Potential for Staining and Odor Retention
While Tervis tumblers are generally stain-resistant, certain beverages, such as coffee and tea, can potentially leave stains or odors over time, especially if the tumbler is not cleaned thoroughly after each use.
