Bag Sealing Devices and Methods

Abstract

A bag sealing device is designed to seal off an already-opened bag, such as a bag of chips. The device has a sheath and a rod. A slit is disposed along an axial direction of the sheath, and the rod is coupled to the sheath and disposed within it. A bag is folded over and inserted into the device such that it enters and exits the device at the slit and is wrapped around the rod. A reaction force from the rod and a reaction force from the sheath combine to cause the bag to be substantially pneumatically sealed.

Description

FIELD OF THE INVENTION[0001]The field of the invention is bag sealing devices and methods.BACKGROUND[0002]The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.[0003]Any time a bag of chips is opened, the chips need to either be eaten in one sitting or the bag must be resealed to maintain freshness. Efforts have been made in the past to address this issue, but each attempt has fallen short for one reason or another.[0004]In one example, bag clips have been produced that allow a person to roll up the end of the bag and clip it shut. While this helps to prevent the chips from becoming stale, it falls short in that air can still move in and out of the bag with relative ease. Chips or other foods sealed in this way will still become st...

AI Technical Summary

Benefits of technology

The technical effects of the patent text are that the sheath has a rounded interior that can match the cross-section of the rod, and the end of the sheath with an opening for the rod has an extending portion to make it easier to seal bags. This design provides a better seal and makes the device easier to use.

Problems solved by technology

Efforts have been made in the past to address this issue, but each attempt has fallen short for one reason or another.

While this helps to prevent the chips from becoming stale, it falls short in that air can still move in and out of the bag with relative ease.

Chips or other foods sealed in this way will still become stale and inedible in a short amount of time.

This design, however, fails to appreciate better alternatives that make it even easier to use such a device.
