Benefits of technology

The system provides a high-strength, high-integrity seal that is non-staining and non-marring, facilitating the strapping of small diameter packages with a portable tool that eliminates the need for a large-foot tool and reduces the risk of rust-related staining.

Problems solved by technology

Although these strapping and seal configurations function well, there are a number of drawbacks.
First, metal strap requires corner protectors for certain goods to prevent damage to the goods.
Moreover, the metal strap is typically fabricated from steel that can rust which can subsequently stain the goods.
For example, stainless steel or plastic pipe can be stained by rust from the strap.
This arrangement is not practicable with small diameter loads because the tool foot cannot rest on the load.
As to the use of a separate element seal the seal is formed from metal as well, and can rust, which can stain the goods.

Abstract

A plastic seal and system is configured for sealing to first and second confronting courses of plastic strap material. The seal includes a body having first and second opposing walls. The first wall has a sealing element formed therein that is bounded by a first wall opening, and the second wall has a sealing element formed therein that is bounded by a second wall opening. The sealing element is connected to the body by one or more frangible connectors. The body defines a central opening for receiving the first and second confronting courses of strap material generally parallel and adjacent to their respective opposing walls. The first sealing element is sealed to the first course of strap material and the second seal element is sealed to the second course of strap material to form a strap seal. A tool and a method for positioning and tensioning a plastic strap around a load are also disclosed.

Description

BACKGROUND OF THE INVENTION [0001] The present invention pertains to an improved tool for tightening a strap around an object or load and adhering the strap onto itself. More particularly, the present invention is directed to a novel plastic or polymeric strap seal and system for sealing plastic or polymeric strap. [0002] Strapping tools are well-known in the art. These tools come in a wide variety of types, from fully manual tools to automatic, table-top tools. These tools are specifically designed for use with either metal (steel) strapping or plastic / polymeric type strapping. The strap is wrapped around the load, tensioned and then overlying courses of the strap material are sealed to one another. The strap courses can be sealed directly to one another (as when plastic strap is welded to itself and metal strap is notched to itself), or they can be joined by a third element such as a seal. The seal, which can be a grit seal for metal or a crimp seal for plastic, is wrapped around ...
