Benefits of technology

The present invention provides a pressure relief valve for an insulated container (cooler). The valve is positioned within a drain plug and allows the user to equalize or narrow the difference between the inside and outside cooler pressures, making it easier to open the cooler lid. The valve can be opened by pressing the outer valve plate towards the cooler, increasing the inside air pressure. The valve is designed with a spring element and O-ring to maintain a closed position, and a user can increase the pressure by pressing the outer valve plate. The technical effect of this invention is to provide a convenient and effective way to control the pressure in an insulated container cooler.

Problems solved by technology

In such locations, ice is often unavailable.
This drop in pressure may result in a pressure that is below atmospheric pressure.
This vacuum may result in the lid being difficult to open.

Abstract

A valve assembly is mounted on a cooler wall comprising a valve opening, the valve opening comprising a seat, the cooler comprising a plurality of walls, a top, and a base. The valve comprises a stem and a valve member, the valve member being adapted for sealing engagement with the seat. When comprising a cooler drain plug, the device comprises a cylindrical main body comprising a threaded post, the main body and threaded post sharing a central longitudinal axis. The threaded post is cylindrical and comprises a through opening concentrically arranged along the longitudinal axis. The threaded post is adapted to be threaded into a cooperatively threaded cooler plug opening of a cooler. The threaded post opening is in fluid communication with a main body opening. The main body opening is adapted to receive the valve assembly.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to pressure relief valves and specifically to an insulated container and drain plug with a valve aspect.BACKGROUND OF THE INVENTION[0002]Insulated containers, popularly known as portable coolers or “ice chests” are used by millions of people to keep food and beverages chilled on a temporary basis. Such coolers are taken to picnics, barbecues, fishing and hunting outings, and other outdoor events where it is desirable to keep perishable items fresh and to refrigerate drinks, such as water and soft drinks. The first portable cooler is believed to have been introduced in the 1950's and rapidly became popular thereafter. Although the materials and technology has changed over the years, early portable coolers shared many common characteristics with those manufactured today. Portable coolers generally comprise an insulated storage compartment and a lid. The lid is often hingedly attached to the storage compartment and, wh...
