Shipping seal for viscous product dispenser

摘要

The actuating lever of the dispenser has an integral valve flap which covers the discharge outlet of the dispenser when the lever is in its standby position, and in order to augment the sealing capabilities of such flap during shipment or storage prior to customer acquisition and use of the dispenser, a disposable sealing tape is provided which is factory-installed so as to overlie the outlet between the latter and the covering valve flap. The tape is provided with a layer of adhesive to promote retention of the tape in sealing relationship with the outlet, and a tab portion of the tape extends from the outlet and is adhered to adjacent portions of the dispenser in such a manner as to facilitate grasping and removal by the user. An overcap enclosing the otherwise exposed actuating lever and discharge spout has internal structure depending from a top wall thereof which bears resiliently against the actuator flap to press the latter tightly against the tape and promote retention thereof in covering relationship to the outlet.
