Inflatable bag for bottles packaging

Abstract

The present invention relates to an inflatable bag for bottles packaging. The bag consists of a pair of connecting unit located at each edge of predetermined gas pocket unit. The connecting unit consists of one vertical and one horizontal welding line forming H shape. The outer edges on the H shape are cut to form U shape breaches. After inflation, due to the stress relief effect of the breaches, the outer part of the gas pocket units beyond the horizontal welding line forms top and bottom sides of cylindrical spaces suitable for containing and protecting cylindrical bottle or can from mechanical impact. One or more pair of connecting unit can be constructed so that plural cylindrical space can be formed to contain and protect plural cylindrical bottles or cans from broken during shipping and handling.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an inflatable bag for bottles packaging having plural cylindrically closed spaces. Between each pair of cylindrical portion, there is a pair of gas pocket units connected by gas channel. The U-shape breach on outer edge of gas pocket units allows formation of top and bottom side of cylindrical portion to enclose spaces. The cylindrical interior space generated after inflation is suitable for packing cylindrical bottles or cans. Due to the geometrical conformity, it provides better protection during shipping and handling.[0003]2. Brief Description of Related Art[0004]Bubble wrap is one of popular devices for packing and protecting commercial articles. It is able to absorb exterior impact by a plurality of uniform air pockets. Its ability of absorbing impact is limited because the air pockets are too small.[0005]U.S. Pat. No. 7,165,677 disclose an air-packing device is configured by first ...

AI Technical Summary

Benefits of technology

[0006]An object of the present invention is to provide an inflatable bag for packaging of bottles or cans in cylindrical shape. The gas pocket units connected by connecting units ensure the formation of cylindrical interior spaces. A pair of connecting units sat between each pair of neighboring cylindrical spaces. A special U-shape breach on outer edge of connecting units provide stress relief and allow formation of top and bottom side of the two neighboring cylindrically closed spaces connected by the connecting unit during inflation. The plural independent cylindrical spaces conform to geometry of bottles or cans and provide better protection against mechanical impact.

[0007]Another object of the present invention is to provide an inflatable bag with configurable plural cylindrical interior spaces in series for bottles or cans with cylindrical shape. The inflatable bag with plural cylindrical spaces facilitates shipping and handling of products with cylindrical shape.

[0009]characterized in that the inflatable bag equipped with one pair of connecting unit which locate at each edge of predetermined set of main and auxiliary gas pocket; the connecting unit consists of vertical welding line and horizontal welding line which form H configuration by binding the upper and lower film; the connecting unit is completed by cutting out the outer edges to form U shape breaches; and due to the stress relief effect of the breach while the inflatable bag is fully expanded by the charged gas, the outer part of the gas pocket units beyond the horizontal welding line are allowed to form the top and bottom side of the two neighboring cylindrical containers which are connected by connecting unit and are suitable for protecting cylindrical bottles or cans from mechanical impact.

Problems solved by technology

Its ability of absorbing impact is limited because the air pockets are too small.

One such device is unable to pack plural cylindrical bottles and provide suitable protection against impact at the same time.
