AI Technical Summary

Benefits of technology

The vacuum storage system is designed to keep food items fresher for longer periods of time by removing air from the storage container. It includes a one-way valve and a vacuum device that can be powered by a rechargeable battery. The system is easy to use, with a simple process to remove air from the container. The technical effects of this invention are improved food preservation and easier air removal from storage containers.

Problems solved by technology

One problem that occurs with the aforementioned containers, including both rigid containers and storage bags, is that latent air may remain trapped within the interior volume after sealing closed the opening.
The trapped air may cause spoiling or dehydration of the food items.

Embodiment Construction

[0030]FIG. 1 illustrates a storage container 100 and a vacuum or evacuation device 150 for evacuating the storage container. The storage container 100 can be a semi-rigid structure including a tub-like or bowl-like base 102 and a removable lid 104. The base 102 and lid 104 form the exterior walls that delineate an interior volume for receiving the food items. The lid 104 can attach to the base 102 by a tongue and groove feature that provides an air tight seal. The base 102 and lid 104 can be made from any suitable material including, for example, molded thermoplastic. In other embodiments, however, the storage container can be any other type of suitable container such as a flexible storage bag.

[0031]To evacuate the interior volume of the storage container 100, a one-way valve element 110 may be attached to lid 102 that communicates with the interior volume. In the illustrated embodiment, the valve element is located at the center of the circular lid but in other embodiments can be l...

Abstract

A vacuum storage system can have a storage container such as a semi-rigid bowl or a flexible thermoplastic bag and an evacuation device for evacuating the container. To draw air from the storage container, the container can be equipped with a one-way valve element attached to a exterior sidewall of the container. The valve element can interface with a nozzle of the evacuation device. The valve element is adaptable between a normal condition in which the valve element is closed, and an altered position in which the valve element is opened. To alter the valve element, the evacuation device includes a contact feature that can contact and displace the valve element.

Description

BACKGROUND[0001]Various types of containers are known to be used for the purpose of storing and preserving food items. Such containers may be in the configuration of rigid dishes or bowls that provide a cavity or interior volume which can be covered with removable lids. Furthermore, the containers may be storage bags such as are typically made from a flexible, low cost, thermoplastic material that is configured to provide an interior volume into which food items can be inserted. To preserve the inserted food items, the storage bag may also include a closing mechanism, such as interlocking fastening strips, for sealing closed an opening through which the interior volume is accessible.[0002]One problem that occurs with the aforementioned containers, including both rigid containers and storage bags, is that latent air may remain trapped within the interior volume after sealing closed the opening. The trapped air may cause spoiling or dehydration of the food items.BRIEF SUMMARY[0003]The...
