Benefits of technology

[0003]The invention provides a rigid storage container having a base providing a storage cavity and a detachable lid that is connectable to the base to adequately seal the contents of the container. To remove air that may become trapped in the container after the base and lid have been connected, the container can include a valve element that communicates with the storage cavity. A valve element can inte

Embodiment Construction

[0023]Now referring to the Figures, wherein like reference numbers refer to like elements, there is illustrated in FIGS. 1 and 2 the parts of a vacuum storage container 100 including a base 102 and a detachable lid 104 that can be connected to the base. To receive items for storage, the base 102 is shaped to provide a void or storage cavity 106. In the illustrated embodiment, the base 102 is rectangular and includes a flat, centrally located bottom panel 108 and four straight, generally upright side panels 110. In some embodiments, the upright side panels can actually angle slightly outward to facilitate nested stacking of multiple bases together. The space opposite the bottom panel 108 and surrounded by the top edges of the side panels 110 provides an opening 112 for accessing the storage cavity. The side edges of each of the side panels 110 are interconnected to bound the storage cavity 106, with the exception of the opening 112, and thereby provide the rectangular shape of the st...

Abstract

A thin-walled vacuum storage container made of a plastic material may have a base providing a storage cavity and a detachable lid connectable to the base for covering the storage cavity. To evacuate the storage cavity, the container also includes a valve element communicating with the storage cavity and that may be adapted to interface with a vacuum device. The base and/or the lid can have at least one wall made by a thin-wall manufacturing process wherein the wall thickness is about 2.5 millimeters or less. Alternately, the base and/or lid can have at least one wall with a flow-length-to-wall-thickness ratio of about 90:1 or greater.

Description

BACKGROUND[0001]A variety of different containers are available for storing and preserving food items for later consumption. Such containers may be flexible, as in the case of plastic storage bags, or may be rigid, as in the case of plastic and glass-walled storage containers. An advantage of rigid storage containers is that they can maintain their shape and thereby protect the stored food items from being crushed. Another advantage is that rigid containers are usually easily washable and therefore can be reusable. Also, it is desirable that rigid containers be temperature and microwave resistant to allow for heating, cooling and freezing of the stored food items within the container. To accomplish these advantages, rigid containers are often made as a relatively thick-walled structure of a stiff material such as Pyrex™ glassware or polycarbonate plastic. Such materials, in addition to being relatively heavy, are also costly.[0002]To preserve the food items within the storage contai...
