DISPENSING DEVICE AND METHODS THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18283655 titled 'DISPENSING DEVICE AND METHODS THEREOF

Simplified Explanation

The apparatus described in the patent application is a dispensing device for a composition, featuring a barrel, an extrusion screw, and a drive mechanism. The extrusion screw includes a shaft with two helical flights of different sizes and pitches.

• The apparatus includes a barrel with an inlet and outlet for the composition.
• The extrusion screw is operated by a drive mechanism and has a shaft with two helical flights of different sizes and pitches.
• The first helical flight has a smaller outer radius than the second helical flight.
• The second helical flight is located distal to the first helical flight.

Potential Applications

This technology could be used in various industries such as pharmaceuticals, food processing, and manufacturing for dispensing precise amounts of compositions.

Problems Solved

This technology solves the problem of accurately dispensing compositions with different viscosities and properties.

Benefits

The benefits of this technology include precise dispensing, efficient mixing of compositions, and reduced waste.

Potential Commercial Applications

Potential commercial applications of this technology include automated dispensing systems, industrial mixing equipment, and pharmaceutical manufacturing processes.

Possible Prior Art

One possible prior art for this technology could be similar extrusion screw devices used in the plastics industry for mixing and dispensing materials.

How does this technology compare to traditional dispensing methods?

This article does not provide a direct comparison between this technology and traditional dispensing methods.

What materials are compatible with this apparatus?

The article does not specify the types of materials that can be dispensed using this apparatus.

Original Abstract Submitted

Provided is an apparatus for dispensing a composition that includes a barrel having an inlet and outlet, an extrusion screw, and a drive mechanism operatively coupled to the extrusion screw. The extrusion screw includes a shaft having a shank end for connection to the drive mechanism and a distal end opposite the shank end. A first helical flight extends around a first section of the shaft, and a second helical flight extends around a second section of the shaft. The second section is located distal to the first section and the first helical flight has a nominal outer radius less than that of the second helical flight, and optionally the first helical flight has a pitch shorter than that of the first helical flight.
