Universal hand mixer
First Claim
1. A universal mixer comprisingan outer cylinder having a front end and a back end,said front fitting to a detachable cap having a valve, andsaid back fitting detachably to a retainer ring;
- an inner cylinder being telescopically nested into the outer cylinder;
said inner cylinder having a front end and a back end;
said front end being sealed with a gasket having one or more holes, andsaid inner cylinder snugly fitting in the outer cylinder;
a piston inserted inside the inner cylinder,said piston comprising a head, a connecting rod and a knob,said head snugly fitting into the inner cylinder,said connecting rod connecting the head and the knob, andthe knob enabling moving the connecting rod inward and outward;
a front handle comprising a handle-piece and a veil-piece,said veil-piece surrounding the front end of the outer cylinder;
a back handle comprising a handle-piece and a veil-piece,said veil-piece surrounding the back end of the inner cylinder;
the outer cylinder being capable of receiving components to be mixed together through the opened cap when the inner cylinder is pulled backwards by holding the front handle and pulling the back handle backwards;
the mixer being capable of initially mixing the components when the cap is closed and a user is holding the front handle and pushing the back handle toward forward, whereby the components enter into the inner cylinder through the holes in the gasket while the inner cylinder moves forward inside the outer cylinder; and
the mixer being capable of further mixing the components when the user holds the front handle and pulls the back handle backward, whereby the inner cylinder moves backward and the piston stays in place causing the components to squeeze between the gasket and the head of the piston and thereby enter through the holes in the gasket into the outer cylinder.

Abstract
A universal mixer for mixing two or more components is provided. The mixer comprises two telescopically nested cylinders, the inner cylinder having a piston that stays in place due to hydraulic pressure inside the cylinders. The components to be mixed are inserted into a space formed by the outer cylinder, a cap and a gasket having one or more holes. The user forces the compounds through the holes by holding the handles of the mixer and pushing a back handle forward thereby causing the inner cylinder to move forward. The inner cylinder preferably has a diameter that narrows slightly from its back to front end. Further mixing is achieved by pulling the back handle backwards whereby the components are squeezed between the piston and the gasket and the components move through the holes in the gasket into the container formed by the outer cylinder.
