A pump dispenser assembly is provided with a rigid or semi-rigid container having a mounting bead at the rim, a flexible lid with an annular mounting portion for gripping the mounting bead, a rigid member laid atop the flexible lid and spanning the rim of the container, and a fluid pump inserted through aligned holes through the flexible lid and rigid member. With this arrangement, a fluid can be pumped out from within the container, without substantial flexing of the flexible lid under the pumping force. |

1. A pump dispenser assembly comprising:
a container having an annular rim with a mounting bead, a sidewall, and a bottom for defining an interior; a flexible lid with an annular mounting portion for releasable mounting on the container by engagement of the mounting bead of the annular rim, a first hole formed through the flexible lid, a bottom surface, and a top surface; a rigid member positioned above the top surface of the flexible lid, the rigid member spanning the container so that the rigid member is supported by opposing sides of the annular rim, a second hole formed through the rigid member; a fluid pump having an actuator, a threaded closure supporting the actuator, a cylinder beneath the actuator, and a dip tube extending from the cylinder and in fluid communication with the actuator through the cylinder, in an assembled configuration the cylinder being inserted through the first hole and the second hole with the threaded closure above the top surface, the dip tube extending into the interior; and a threaded collar positioned beneath bottom surface of the flexible lid, in the assembled configuration the threaded collar tightened to the threaded closure to sandwich the flexible lid to the rigid member so that a pumping force on the actuator is transferred through the rigid member and to the container through the annular rim to prevent substantial deflection of the flexible lid. |
