Abstract

A system for enhanced conveying of flexible packages includes a packaging system, an inflation system, and a conveying system. The packaging system is configured to place an object in a flexible package. The inflation system is configured to insert a gas into the flexible package. The packaging system is further configured to seal an edge of the flexible package in an inflated state with the object and the inserted gas inside the flexible package. The conveying system is configured to convey the flexible package while the flexible package is substantially in the inflated state. The flexible package is configured to permit gas to escape the flexible package at a controlled flow rate such that the flexible package remains substantially in the inflated state while being conveyed by the conveying system and the flexible package transitions to being substantially in a deflated state after being conveyed by the conveying system.

First claim

What is claimed is:

1. A system comprising:
a packaging system configured to place an object in a flexible package;
an inflation system configured to insert a gas into the flexible package from a source of pressurized gas, wherein the packaging system is further configured to seal an edge of the flexible package in an inflated state with the object and the inserted gas inside the flexible package; and
a conveying system configured to convey the flexible package while the flexible package is substantially in the inflated state;
wherein the flexible package is configured to permit gas to escape the flexible package at a controlled flow rate such that the flexible package remains substantially in the inflated state while being conveyed by the conveying system and such that the flexible package transitions to being substantially in a deflated state after being conveyed by the conveying system; and
wherein the flexible package includes one or more vent holes configured to permit the gas to escape the flexible package.

2. The system of claim 1 , wherein the system is located in a shipping facility, and wherein the flexible package is configured to be shipped from the shipping facility when the flexible package is substantially in the deflated state.

3. The system of claim 1 , further comprising:
a film dispenser configured to supply film to the packaging system, wherein the packaging system is configured to form the flexible package from the film.

4. The system of claim 3 , wherein the film includes the one or more vent holes.

5. The system of claim 4 , wherein at least one characteristic of the one or more vent holes is selected to control the controlled flow rate of the gas out of the flexible package.

6. The system of claim 5 , wherein the at least one characteristic includes one or more of a size of the one or more vent holes, a shape of the one or more vent holes, a number of the one or more vent holes, a location of the one or more vent holes, or a pattern of the one or more vent holes.

7. The system of claim 5 , wherein the at least one characteristic of the one or more vent holes is selected to provide the flexible package with a type of functionality.

8. The system of claim 7 , wherein the type of functionality includes at least one of aid in opening of the flexible package, prevention of damage to the flexible package, or improved ability to reuse the flexible package.

9. The system of claim 4 , wherein the conveying system includes one or more of a conveyor belt or a plurality of rollers.

10. The system of claim 1 , wherein the inflation system includes the source of pressurized gas, and wherein the source of pressurized gas includes one or more of a container of pressurized gas or a gas compressor.
