Abstract: A single-serve capsule for preparing a beverage in a beverage apparatus. The capsule includes an inlet end, an outlet end arranged opposite to the inlet end, and a capsule base which closes the outlet end. The capsule base includes an outside area, an outside edge, weak points which open, break and/or tear as a result of a fluid pressure of hot water in the interior of the capsule, and arcuate thin spots arranged next to each of the weak points. The arcuate thin spots provide for a uniform guidance of a plastic melt, do not break or tear open under the fluid pressure of the hot water, and form ramp-like sloping surfaces to increase a surface of the accurate thin spots upon which the fluid pressure of the hot water acts.

Abstract: The invention relates to a pin-shaped device for applying a liquid to a surface, having a tank (8) receiving the liquid and an application head (1) connected to the tank, on the exterior of which on the side facing away from the tank a liquid-permeable application body is mounted coaxially, to which liquid is fed from the tank, wherein the outer diameter (1) of the tank (8) is 1/3 to 2/3 of the outer diameter of the application head (1), and the tank (8) protrudes outward coaxially to the application head (1).
