A reusable takeaway cup with a swiveling plug lid
A reusable beverage cup with a fitted lid that has a drinking opening and a rotatable cover piece with a plug that seals the opening when rotated into place. The rotatable member also covers or uncovers a separate air/steam vent and carries a curved track or slot to channel hot air or steam. Intended for people who carry hot drinks for takeaway use.
(57) What the patent covered

The main independent claim covers a container with a lid that has a sipping opening and an air hole, plus a rotatable member fixed to the lid with a bottom-mounted plug shaped to match and sealingly fit the sipping opening in a first (closed) position. The rotatable member can swivel laterally away from that first position, covers the air hole when closed, and includes an arcuate guiding track with a mating slot to carry hot air or steam released through the air hole.
Distinguishing feature: A rotatable lid piece with a bottom-fixed plug that both seals a matching-shaped sipping opening and covers a separate vent while providing an arcuate slot to channel released steam.
Novelty 3/5. The idea is a focused mechanical improvement to a familiar reusable cup lid; swiveling covers and vent holes were known in travel cups, but the combined matching-shaped plug plus guided steam slot was not common when filed.
Manufacturing
Injection-molded polymer lid and rotatable member, overmolded or press-fit silicone sealing portion for the plug, injection- or blow-molded container body, simple mechanical assembly press-fitting the rotator onto the lid.
Materials: BPA-free polypropylene or similar thermoplastic for lid and rotator, Silicone or thermoplastic elastomer (TPE) for a sealing plug insert or gasket, Stainless steel or polypropylene for the container body (likely), Neoprene or silicone for an insulating sleeve (likely).
Manufacturability 4/5. Few molded parts (lid, rotator, plug gasket, container, sleeve); requires tooling for matched molded features and assembly to retain the rotator while allowing smooth swivel action.

Before manufacturing
No related continuation or divisional patents in force were found. Design patents, trademarks and unrelated patents may still cover the product.
None obvious; practical issues include wear and sealing reliability of the plug, steam venting safety, and a crowded market for reusable cups.
