Recloseable storage bag with porous evacuation portal

Abstract

A recloseable storage bag is disclosed which may include first and second sides having closed sides and an open top. Primary closure members may be provided proximate the top, with a secondary closure element being provided in one of the sides to enable gas to be evacuated from the bag after the primary closure members are closed. The secondary closure member may further include the ability to prevent liquid from exiting the bag therethrough.

Description

FIELD OF THE DISCLOSURE[0001] The disclosure generally relates to bags and, more particularly, to recloseable food storage bags.BACKGROUND OF THE DISCLOSURE[0002] Reclosable storage bags are well known, especially with regard to food storage. Such bags are generally made out of a plastic film and have two side walls which are sealed around the edges. Such material is fluid impermeable, relatively inexpensive, and can be manufactured in transparent form thereby facilitating content identification. Accordingly, plastic bags have become the dominant product of choice in the area of food storage bags.[0003] Such bags are typically recloseable and substantially sealable. One common approach to provide such features employs closure members at a top edge of a bag having first and second thermoplastic layers folded or heat sealed along bottom and first and second side edges. The closure members may be provided in the form of mating male and female profiles such as those provided by the pres...

Problems solved by technology

While the primary closure found at the top of many plastic bags provides an airtight seal, air remaining enclosed in the bag after closure enables bacterial growth and therefore hinders the preservation and freshness the bags are intended to maintain.
