DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 1 shows a compartmentable plastic bag 10 particularly suited for transporting glass bottles B, such as wine bottles, and the like. The bag 10 has a collapsible separator 12 adapted to be serpentined between adjacent bottles B
to prevent the bottles B from banging against each other in direct glass to glass contact.
The integrated separator 12 obviates the need to place the bottles in individual bags, such as individual paper bags, within the larger plastic bag 10. As will be seen hereinafter, the separator 12 can be collapsed against an interior surface of the bag to provide full access to the internal receptacle space of the bag and separated from the bag interior surface to "compartmentize" the bag receptacle space and act as a flexible bottle separator or divider, as shown in Figs. 1 and 2.
More specifically, the bag 10 generally comprises coextensive front and back panels 14, 16 joined by a bottom gusset 18 (Fig. 4) and sealed together along their longitudinally extending side edges to form a bag having a closed bottom and a top open mouth. It is understood that the front and back panels 14 and 16 could be otherwise joined together. For instance, the front and back panels 14 and 16 could be integrally connected without any bottom gusset. The bottom of the bag 10 could, for instance, be formed by a simple fold or even by heat sealing the bottom edges of separate front and back panels together.
The bag 10 is provided with a top handle portion 18. The handle portion 18 comprises hand-receiving cut-outs 20 defined through the front and back panels and 16. Preferably, a top portion of the front and back panels 14 and 16 is folded over inwardly in superimposed relationship with a reinforcing layer 22 and heat sealed along a transversal seal line 24 to provide a reinforced multi-layer handle construction, as best shown in Fig. 4. The reinforcing layer 22 is preferably cushioned to provide hand comfort to the carrier. The reinforcing layer 22 can be provided in the form of a plastic film, such as a high density polyethylene film, in which air is injected to provide a desired degree of cushion.
The separator 12 is also preferably formed from a film or web of high density polyethylene material injected with air. The air injected in the separator 12 provides a cushion effect for absorbing impacts and shocks between adjacent bottles B in the bag 10, thereby reducing the chances of bottle breakage. The separator 12 is provided in the lower half portion of the bag 10 and is preferably disposed to prevent shoulder to shoulder and base to base contact between adjacent bottles.
Because of their often outwardly projecting shape and configuration, the shoulder and the base of the wine bottles are more likely to come into contact and as such it is preferable that the bottom and top edges 26 an 28 of the separator 12 extend respectively below and above the base and the shoulder of the bottles to avoid any glass to glass contact between the bottles. However, as shown Fig. 1, the separator 12 could be disposed to only cover an intermediate portion of the bottles B between the base and the shoulder thereof.
As shown in Fig. 3, the separator 12 has a width equal to the width of the front and back panels 14 and 16 when the bag 10 is in its flattened condition.
The separator 12 has first and second opposed ends 30 and 32 heat sealed to opposed side edges of the bag 10. It is understood that the separator 12 could be otherwise attached or joined to the bag panels 14 and 16. According to the illustrated embodiment, the separator 12 is solely connected to the bag panels by its ends 30 and 32. The separator 12 is otherwise free to move relative to the front and back panels 14 and 16.
Bottles B can thus be alternately placed on opposed sides of the separator 12 with the separator 12 waving in a sinuous-like manner between the bottles, as shown in Fig. 2.
Accordingly, the separator 12 can divide the interior space of the bag 10 in a number of compartments corresponding to the number of bottles to be carried, the number of compartments being limited by the overall size of the bag 10. However, when the user subsequently wishes to re-use the bag 10 to carry other items requiring a single compartment defining a greater carrying volume, the separator 12 can be manually collapsed in a flattened condition against an interior surface of one of the bag panels 14 and 16 to provide full access to the interior volume of the bag 10. This provides great flexibly in use which cannot be afforded by conventional bags having a fixed number of compartments.
Figs. 5 and 6 schematically illustrate the manufacturing process of the bag 10. As shown in Fig. 5, the bag is preferably manufactured from a main roll of high polyethylene film 40 and three rolls of air injected polyethylene films 42, 44 and 46.
The films 42, 44 and 46 are unrolled over the main film 40 in unison therewith. Films 42 and 44 are used to make the reinforced handle portion 18 and correspond to layer 22 in the assembled bag as shown in Fig. 4. The intermediate air injected film 46 is used to make the separator 12 in the assembled bag. As shown in Fig. 5, the intermediate film 46 is disposed next to the median axis 48 of the main film 40. The median axis 48 corresponds to the fold line about which the main film 40 is folded in two to form the front and back panels 14 and 16 of the bag 10. However, before folding the main film 40 about median axis 48, the opposed lateral end portions of the main film 40 are folded over inwardly in superposed relationship with the films 42 and 44, respectively. As also shown in Fig. 6, the median film is folded on opposed sides of the mediam axis to for the bottom gusset 18. The hand-receiving cut-outs 20 can be punched out before or after [he folding operation. After having been folded, the folded lateral end portions are heat sealed to the reinforcing film 42 and 44. Thereafter, the main film 40 is folded upon itself about the median axis 48 with the intermediate film 46 lying between the two haft portions of the main film 40.
After completing this folding operation, the films 40, 42, 44 and 36 are cut and heat sealed along transversal line 50 and sealed along pre-cut edge 52 to form the sealed side edges of the bag and simultaneously attaching the intermediate film to the side edges of the newly formed bag.
The above description is meant to be exemplary only, and one skilled in the art will recognize that changes may be made to the embodiments described without departing from the scope of the invention disclosed. Modifications which fall within the scope of the present invention will be apparent to those skilled in the art, in light of a review of this disclosure, and such modifications are intended to fall within the appended claims.

For instance, the front and back panels 14 and 16 could be integrally connected without any bottom gusset. The bottom of the bag 10 could, for instance, be formed by a simple fold or even by heat sealing the bottom edges of separate front and back panels together.
The bag 10 is provided with a top handle portion 18. The handle portion 18 comprises hand-receiving cut-outs 20 defined through the front and back panels and 16. Preferably, a top portion of the front and back panels 14 and 16 is folded over inwardly in superimposed relationship with a reinforcing layer 22 and heat sealed along a transversal seal line 24 to provide a reinforced multi-layer handle construction, as best shown in Fig. 4.

However, as shown Fig. 1, the separator 12 could be disposed to only cover an intermediate portion of the bottles B between the base and the shoulder thereof.
As shown in Fig. 3, the separator 12 has a width equal to the width of the front and back panels 14 and 16 when the bag 10 is in its flattened condition.
The separator 12 has first and second opposed ends 30 and 32 heat sealed to opposed side edges of the bag 10. It is understood that the separator 12 could be otherwise attached or joined to the bag panels 14 and 16. According to the illustrated embodiment, the separator 12 is solely connected to the bag panels by its ends 30 and 32. The separator 12 is otherwise free to move relative to the front and back panels 14 and 16.
Bottles B can thus be alternately placed on opposed sides of the separator 12 with the separator 12 waving in a sinuous-like manner between the bottles, as shown in Fig. 2.
