Spout Strap

Anti-detachment container-mounted strainer spout using a torsion spring dual spout

This technology is a spout strap that secures a first spout, which fits tightly around the outer circumference of a container opening, to the container with a strap. A second spout with multiple strainer holes is coupled to the same rotation axis, allowing contents to be strained while being poured. A torsion spring on the rotation axis maintains the gap between the two spouts.

Existing detachable spouts have the body and clip integrated, leading to issues where the spout easily detaches from the container. C-shaped auxiliary spouts have an inner radius fixed to specific bottle necks, limiting their use to containers of different sizes.

This technology uses a strap that wraps around and secures to the outer circumference of the container, preventing detachment and allowing it to be mounted on containers of various sizes. An elastic wall prevents contents from leaking out the sides. It can be applied to kitchen pots, airtight containers, and beverage accessories, allowing for clean pouring and straining even with containers that lack a spout.

Key Features:

• A first spout that fits tightly around the outer circumference of a container opening to form a discharge passage, with an elastic wall extending along the outer edge to prevent leakage.
• A strap configuration that extends from the first spout and mounts to the outer circumference of the container to secure the spout in place.
• A second spout featuring multiple strainer holes to filter contents from the container, rotatably coupled to the strap via a rotation axis along with the first spout.
• A torsion spring installed on the rotation axis, with both ends supporting the upper surface of the first spout and the lower surface of the second spout to maintain a gap between them.
