Embodiment Construction

[0019] Referring now to the drawings, in which like reference numerals refer to like elements, a typical type of flexible storage bag 100 for storing food is exemplarily shown in FIG. 1 . The storage bag includes a first side wall 102 and an opposing second side wall 104 that overlaps and joins the first side wall to provide an interior volume 106 . The first and second side walls 102, 104 may be made from a flexible web of thermoplastic material. Examples of suitable thermoplastic materials include: polyethylene (PE), high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), polypropylene (PP), ethylene vinyl acetate ( EVA), nylon, polyester, polyamide, ethylene vinyl alcohol (ethylene vinyl alcohol), and can be formed as a single layer or multiple layers. The thermoplastic material may be transparent, translucent, opaque or tinted. Furthermore, the material for the side wall may be an air impermeable material.

Abstract

A closure element is used for closing an opening disposed through the flexible sidewall of a storage bag such as those used to store food items. Storage bags of this type provide an internal volume accessible via the opening. The closure element includes a first fastening strip and an interlocking second closure strip. The first and second fastening strips include complementary, engagable first and second closure profiles. To hermetically seal the internal volume, at least a portion of the first or second fastening strip can include a sealant. The sealant can be a displaceable fluid, fluid-like substance, or wax-like substance such as an oil or a gel. When the closure profiles are engaged, the sealant provides an air tight barrier sealing the internal volume.

Description

technical field [0001] The present invention relates generally to storage containers, and more particularly to flexible storage bags designed with closure means such as interlocking fastening straps. The invention is especially suitable for the field of food storage. Background technique [0002] Storage bags are commonly used for a variety of purposes including, for example, food storage. Such storage bags are typically made of low cost, flexible thermoplastic material and provide an interior volume into which food can be placed. To access the interior volume, storage bags are typically formed with an opening. Additionally, in order to preserve food or prevent the contents from spilling out of the bag, the storage bag may also include closure means comprising interlocking fastening strips for closing said opening. In order to preserve food, it is also known to provide a storage bag or similar with a one-way valve element for venting the inner volume after interlocking th...
