VENTING TECHNOLOGY OVERVIEW

For years, there has been a twofold need for vented cap technology:

1.) The venting of gases that can build up in a sealed package with certain types of products, causing blow-out or product leakage.

2.) To prevent "Paneling" that can occur when packages are filled with hot material, sealed, and the material cools and shrinks creating a vacuum. Previous attempts at venting technology have incorporated perforated and/or convoluted lining materials, membranes, and combinations of these along with other mechanical features.

Traditionally these devices have addressed one of the needs but not both. Existing methods have high and low end limitations on their effectiveness range.

The Pearce Venting Technology

The Pearce Venting Technology uses uniquely gated venting channels and does not depend on specific liner materials or configurations. It does not depend on any mechanical devices.

The Pearce Technology can be used to vent internal buildup of gasses and it can be used to relieve the vacuum that is created when hot-filled product cools.

This technology can be adapted to handle high and low end criteria over a wide range of products and sizes. The technology can be incorporated into Orifice Reducers, Sleeved Inserts, or directly into the cap itself.

VENTING TECHNOLOGY APPLICATIONS

Hair and Skin Care products.

By eliminating the paneling associated with hot-filled product, filling can be accelerated by up to 30%.

Household products.

Many household products create gaseous pressures when in sealed containers. The venting relieves these pressures but prevents leakage of product.

Food products.

Certain food products such as Ripe Olives will continue to ferment after packing. This fermentation process can cause expansion. With venting the increased pressure is released without any product leakage.

Industrial products.

Can be used anywhere that pressure needs to be released, or where hot filling causes a vacuum.
