One-touch tumbler

Spring-loaded airtight tumbler with a pop-up straw

This technology features a one-touch tumbler that uses a compression spring between the mounting part covering the container opening and the cover above it. Pressing the cover lowers the lid height, exposing the hidden straw. The straw's upper opening is located on the side, keeping it sealed by the inner wall of the cover's passage hole when retracted.

While regulations on disposable cups have increased tumbler usage, existing straw-type lids are cumbersome due to their hinged opening and closing mechanisms. Furthermore, these designs often suffer from leaks or contamination of the straw tip even when retracted.

This technology allows the straw to be deployed with a single press, while an interlocking unit—consisting of vertical and horizontal moving members and a flexible member—prevents the cover's horizontal protrusion from rising, keeping the straw exposed. Applicable to portable tumblers, children's straw cups, and car thermoses, it enables product differentiation by allowing one-handed straw access while preventing leaks and contamination during storage.

Key Features:

• A one-touch tumbler comprising a container for beverages, a straw, and a lid that seals the storage space and hides the straw, with the straw being exposed when the lid is pressed.
• A configuration where a compression spring is placed between the mounting part covering the container opening and the cover above it, exposing the straw above the cover when the cover is pressed down.
• A configuration where the straw's upper opening is formed on the side, sealing it against the inner wall of the cover's passage hole when the straw is hidden inside the lid.
• A configuration where an interlocking unit consisting of vertical and horizontal moving members and a flexible member moves when the cover is pressed down, blocking the horizontal protrusion of the cover from rising.
