Device for encapsulating flavoring solids and container having such a device

A system, comprising:

• a container comprising a cup-shaped housing having a wall, a bottom, and an opening opposite the bottom;
• a lid for covering the opening, wherein the lid is configured to close and open via a rotary motion;
• and
• a device comprising:
• a fixed element having an upper side and secured to a ring;
• and
• a blade-like rotary slide comprising at least one engaging element, the rotary slide supported rotatably between an initial position and an end position at the fixed element, which rotary slide in its end position limits a space accepting the solid flavoring substances, wherein in the end position of the rotary slide, the space accepting the solid flavoring substances is delimited by the fixed element, the rotary slide, and an upper closing element,
• wherein the ring, the fixed element, the upper closing element, and the rotary slide form a unit configured to be removably inserted through the opening of the container and into the container with the ring and the upper closing element arranged adjacent to the opening of the container and the engaging element is configured to contact a section of the lid of the container to rotate the rotary slide to the end position when the section is rotated to close the opening of the container.
