Some embodiments are directed to a bodily fluid sample collection device for the collection of naturally expressed bodily fluids and include a cap engageable with a tube to close a mouth of the tube. The cap includes a chamber for containing a reagent. The tube defines at least partly a sample collection space for receiving the naturally expressed bodily fluid. The cap comprises first and second cap portions relatively movable with respect to each other. The first and second cap portions are configured such that, responsive to engagement of the cap on the tube, one of the cap portions is caused to move integrally relative to the other cap portion to open the chamber and permit fluid communication between the chamber and the sample collection space. The reagent in the chamber is thereby permitted to mix with the bodily fluid in the sample collection space. A method of organizing and processing samples is also described.

A packaging system for at least one product preparation component, having a first container for storing a first product preparation component, a second container for storing at least one further product preparation component, and a closure device which seals off an opening in the first container from the environment by way of a closure element having a coupling apparatus to couple the second container to the closure device and establishes a fluid connection between the first container and the second container. The invention additionally relates to a method for handling at least one product preparation component. The aim of the invention is to ensure a reliable packaging system which allows a user-friendly handling of the contained product preparation components. The closure element and the coupling apparatus are joined together as separate components in a non-detachable manner forming the closure device.

A cover device includes: a guide module which is coupled to an upper end portion of the container, has an upward inclination at a predetermined angle, has an inclined protruding unit that protrudes, and is formed with a communication port through which the inside and the outside of the housing space communicate; a discharge module which is formed in a long pipe shape, and in which one side along a longitudinal direction penetrates the communication port and is disposed inside the container, the other side is exposed to the outside to form a discharge port; and a fixing module which is fixedly coupled to the inclined protruding unit in a state in which the other part of the discharge module penetrates, and is formed so that the discharge module is pressed toward the guide module.
