Abstract: Provided is a package made of a composite material is represented and described, including a package base with two front base corners and with two rear base corners, a package gable with two front gable corners and with two rear gable corners, and a package base body with a front panel, a first side panel, a second side panel and a rear panel. The package base and the package gable are arranged on opposite sides of the package base body. The composite material has a polymer inner layer, a polymer outer layer and a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. In order to enable the manufacture of packages with even more complex geometries without impairing the rigidity of the package, it is proposed to provide a third sleeve fold line, which has a plurality of sections, which each adjoin a side panel and the rear panel, and of which at least one section is curved.

Abstract: A micro reservoir, particularly for integration in a microfluidic flow cell, with a storage space for receiving a fluid and being in connection with an outlet duct for the fluid, wherein a cancelable lock for the fluid is formed. A mechanism is provided for canceling the lock without pressure of the fluid acting on the lock. The mechanism preferably mechanically destroys the lock.
