Self-inking stamp having ink pad container with recesses engaging guiding and centering projections on housing sidewalls
View Patent ↗A self-inking stamp is filled with ink by the top thereof at a pressure. The stamp has a housing and a stamping unit which is connected to an actuating element, movably arranged in the housing and provided with stamping characters. The housing also has a drawer which is provided with at least one pushing opening through which an inkpad container can be inserted. The drawer is provided with an opening on the lower side thereof in front of the stamping unit, which makes it possible to ink the stamping characters in an upward turned position by applying them to the ink pad which is arranged in the container thereof. Guiding and centring projections for the ink-pad container are arranged in an insertion direction on two opposite sides of the drawer.

2. A self-inking stamp according to claim 1 , wherein the guiding and centering projections ( 26 ) are formed by ledges extending in the direction of insertion.
3. A self-inking stamp according to claim 2 , wherein the ledges are substantially rectangular, seen in front view.
4. A self-inking stamp according to claim 1 wherein the ink pad container ( 4 ) has a lower rim, which is provided on lower side portions of the ink pad container when inserted in the insertion compartment.
5. A self-inking stamp according to claim 4 , wherein the recesses ( 27 ) are provided on the lower rim of the ink pad container ( 4 ).
6. A self-inking stamp according to claim 1 , wherein the recesses ( 27 ) on their side which is the upper side in the inserted state of the ink pad container ( 4 ) are delimited by ledge projections ( 28 ) on the side walls ( 23 ) of the ink pad container ( 4 ).
7. A self-inking stamp according to claim 1 , wherein at least one resilient retention element ( 17 , 18 ) is arranged in the insertion compartment ( 3 ) for resilient abutment on the ink pad container ( 4 ).
8. A self-inking stamp according to claim 7 , wherein the resilient retention element ( 17 , 18 ) is arranged on the upper side of the compartment, located opposite the opening ( 25 ′) provided on the lower side of the insertion compartment ( 3 ).
9. A self-inking stamp according to claim 7 , wherein the resilient retention element ( 17 , 18 ) is designed as a snap-in element for snapping engagement on the ink pad container ( 4 ).
10. A self-inking stamp according to claim 9 , wherein the resilient retention element ( 17 , 18 ) has a snap-in projection ( 20 ) in the shape of a knob.
11. A self-inking stamp according to claim 9 , wherein the ink pad container ( 4 ) has a bottom area which faces upwardly in the inserted position, wherein the bottom area includes a depression for snapping engagement of the resilient retention element.
12. A self-inking stamp according to claim 11 , wherein the depression ( 21 ) is formed by a groove extending in a direction corresponding to the direction of insertion of the ink pad container ( 4 ) into the insertion container.
13. A self-inking stamp according to claim 12 , wherein the depression ( 21 ) is delimited by an end wall ( 17 ′, 18 ′) on both ends.
14. A self-inking stamp according to claim 7 , wherein two resilient retention elements ( 17 , 18 ) are arranged in successive alignment in the insertion direction of the ink pad container ( 4 ).
15. A self-inking stamp according to claim 14 , wherein the two resilient retention elements ( 17 , 18 ) are tongue-shaped snap-in elements having a snap-in projection ( 20 ) on each one of their free ends that face away from each other.
