Yes, Stanley uses lead in the manufacturing process for its popular tumblers.
While lead is present in Stanley cups, it is specifically used as part of the sealing material located at the very bottom of the tumbler. This lead component is encapsulated by a durable, protective stainless steel cover. According to a Stanley spokesperson, the lead only poses a risk of exposure if this bottom cover detaches from the cup, thereby exposing the internal sealing material.
Understanding Lead's Role and Risk in Stanley Tumblers
Under normal use, with the protective cover intact, the lead is not accessible and does not come into direct contact with the beverage or the user. The design aims to fully contain the lead within the product's base, ensuring it remains sealed away.
Key Points Regarding Lead in Stanley Cups:
- Manufacturing Use: Lead is utilized as a sealing material in the base of the cup during the production process.
- Encapsulation: This lead is situated under a protective stainless steel cover at the bottom of the tumbler.
- Exposure Condition: Potential exposure to lead is only a concern if the bottom cover of the tumbler comes off, which would expose the internal sealing material.
- Normal Use: When the bottom cover remains intact, the lead is safely contained within the product and poses no direct risk to the user.
Therefore, the presence of lead is limited to a specific, sealed component of the cup's base, and is not meant to be exposed during typical use.
