Embodiment Construction

[0060] figure 2 Is a side view of a stickless dispenser 10 for manual dispensing of squeezable substances. The dispenser 10 includes a cylinder 12 which lacks an upper "half" so that a tube or container of extrudable substance can be loaded into and removed from the dispenser 10. This "half-cylinder" 12 for accommodating a tube or tank is still referred to herein as a cylinder.

[0061] A housing that acts as a handle 14 is attached to the cylinder 12 or is integrally part of the cylinder 12 . A swingable trigger 16 is pivotally connected at a pivot point P to the lower part or tail end 15 of the handle 14 . When the trigger 16 is firmly grasped, the trigger 16 can be easily retracted into the handle 14. When the trigger 16 is firmly grasped, the trigger return spring ( figure 2 not visible in ) are compressed. When the user releases the trigger 16, the elastic force of the trigger return spring causes the trigger 16 to return to its original position (withdraw from the ...

Abstract

A piston and piston rod for a rodless dispenser for extrudable material are configured such that compressive force exerted on the piston from a push chain causes a reactive torque to be created that locks the links of the chain together. The push rod is located away from the piston's geometric center.

Description

[0001] Related applications [0002] This application is a continuation-in-part of US Patent Application Serial No. 12 / 684,597, filed January 8, 2010, and entitled Leverless Dispenser. technical field [0003] The present invention relates to a dispenser for extrudable substances, and more particularly to a transmission in a dispenser for extrudable substances. Background technique [0004] Mechanical dispensers for viscous or squeezable substances include common piston caulk guns available at any hardware store, and small hand-held devices for rolling up a flexible tube such as a tube of toothpaste. Most squeezable substance dispensers have a piston attached to the end of an elongated piston rod. The piston advances in a partial cylinder whose shape is reminiscent of a tank, hereinafter referred to as the storage cylinder or simple cylinder, whose function is to accommodate Cylindrical container for squeezable substances. [0005] An extrudable substance contained in a c...
