Seep-resistant panel

A panel for covering a surface of a room, comprising:

• a panel element extending in a longitudinal direction and in a transverse direction for transferring use loads introduced at a top side of the panel element to a bottom side of the panel element facing the surface of the room, wherein the top side is spaced apart from the bottom side in a thickness direction;
• and
• a locking hook projecting from the panel element in the longitudinal direction for latching into a receiving groove of a second panel,
• wherein
• an end face reference plane of an end face of the panel element extending away from the locking hook extends obliquely in the thickness direction while forming an obtuse angle with the locking hook, and wherein the obtuse angle between the locking hook and the end face reference plane remains constant in the transverse direction, and wherein the end face comprises end face receiving pockets arranged alternately in the thickness direction and extending from the end face reference plane, said end face receiving pockets are capable of receiving projecting second panel latching bumps of the second panel, and wherein the end face comprises end face latching bumps projecting from the end face reference plane, said end face latching bumps are capable of engaging into corresponding second panel receiving pockets of the second panel, wherein in at least one cross-sectional plane in the transverse direction the end face receiving pockets merge directly into the end face latching bumps only via one inflection point of a cross-sectional profile of the end face lying in the end face reference plane, wherein the obtuse angle α is 92°<α≤100°.

• and
• a tongue body projecting from the panel element in the longitudinal direction for receiving without play, a locking hook of a second panel which can be latched into a receiving groove formed with the aid of the tongue body and/or the panel element,
• wherein
• a tongue end face reference plane of a tongue end face of the tongue body facing away from the panel element extends inclined with respect to the thickness direction, while forming an acute angle with the contact surface of the tongue body facing the locking hook wherein the contact surface of the tongue body merges into the tongue end face via a counter-rounding, and wherein the acute angle β is 80°≤β≤88°, and wherein the tongue end face comprises receiving pockets arranged alternately in the thickness direction and extending from the tongue end face reference plane capable of receiving projecting second panel latching bumps of the second panel, and wherein the tongue end face comprises latching bumps projecting from the tongue end face reference plane for engaging into corresponding second panel receiving pockets of the second panel, wherein in at least one cross-sectional plane in the transverse direction the receiving pockets merge directly into the latching bumps only via one inflection point of a cross-sectional profile of the tongue end face lying in the tongue end face reference plane.
