Benefits of technology

The present invention is a storage device that can keep items stored inside in a vacuum while still supporting them and protecting them. It uses gravity to help quickly create and release the vacuum. This solves the problem that previous configurations had, which was not being able to keep items in a vacuum without losing their support and protection.

Problems solved by technology

Rigid vacuum containers suffer from several inherent limitations.
This is due to the fact that drawing air from a rigid compartment requires a large vacuum force and produces external forces on the compartment which can lead to collapse of the compartment.
In addition, drawing air out of a rigid compartment can take several minutes and requires a large capacity vacuum pump due to the buildup of negative pressure within the rigid compartment.
Although vacuum bags can be used to store items under near-complete vacuum, such bags are harder to handle and store due to their pliable nature.

examples

[0075]Reference is now made to the following example, which together with the above descriptions, illustrate the invention in a non limiting fashion.

[0076]A prototype of the present storage device was constructed by modifying an existing container to include a 3D-printed lid having an integrated vacuum pump (12V piston-type vacuum pump) and a one way valved port. A compressible seal actuatable between compressed and non-compressed states via a lever was integrated into the lid.

[0077]A 800 ml bag was positioned within the container with the bag sides overlapping the rim (FIG. 7). About 200 grams of flour were placed inside the bag and the lid was sealed against the bag and sidewalls of the container (FIG. 8) by pushing down the sealing lever. The pump was switched on for 30 seconds and the bag was collapsed and withdrawn up (FIG. 9). Vacuum was maintained for several days without need for further pumping.

[0078]It is appreciated that certain features of the invention, which are, for c...

Abstract

A storage device is provided. The storage device includes a container having a bottom, side walls, and a top opening defined by a rim and a bag for storing items, the bag having an opening attached to the side walls at, or near the rim. The storage device further includes a lid and a port for withdrawing fluid from an internal volume of the bag to thereby collapse the bag while pulling it towards the lid such that when the bag is collapsed, it is suspended within the container.

Description

FIELD AND BACKGROUND OF THE INVENTION[0001]The present invention relates to a device for storing items and, more particularly, to a storage device that includes a bag suspended within a rigid container for storing items under vacuum.[0002]Spoilage of perishable items such as food and medication is a major economic, environmental and social concern. Spoilage can be caused by exposure of stored items to microorganisms, insects or rodents or to oxygen and humidity.[0003]Numerous approaches have been developed to help preserve perishable items.[0004]For example, storing items under vacuum minimizes exposure thereof to humidity and oxygen and extends their shelf life.[0005]One example of a vacuum sealing system is the Foodsaver® system which utilizes a bag / container and sealing device to seal food items under vacuum and keep it fresh up to 5 times longer than ordinary storage devices like zipper bags, foil, plastic wrap, lid-top containers and the like.[0006]More complicated vacuum syste...
