Device for inserting a plugging compound into an opening

A device for introducing a plugging compound into a borehole, the device comprising:

• a sleeve with a cavity for receiving the plugging compound, one end of the sleeve having a discharge opening fluidly connected to the cavity, for discharging the plugging compound, the opposing end of the sleeve including an upper opening through which a piston together with a feed plate protrudes into the cavity, the piston being movable along a piston axis parallel to the sleeve in such a way that the feed plate can be displaced in the cavity in order to allow the plugging compound to be received and dispensed;
• a support section, permanently attached to the sleeve adjacent the discharge opening and extending laterally from the sleeve, wherein the support section has an oval shape and comprises an upper surface, an end face opposing the upper surface and defining the discharge opening, a support surface opposing the upper surface and displaced from the discharge opening, a support surface plane perpendicular to the piston axis defined by the support surface and the discharge opening, and at least two cavities are defined between the end face, the support surface, the upper surface and the support surface plane.
