## CPC

- B65D 81/3266: {separated by a common rupturable seal, a clip or other removable fastening device}
- B65D: CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR FITTINGS THEREFOR; PACKAGING ELEMENTS; PACKAGES

## Abstract

A package having two or more selectively isolated compartments and a mixing region is disclosed. A mixing region can be included between the mixing compartments, with respective access devices (e.g., zipper or film member) provided to provide selective communication between the compartments and the mixing region. One or more pull members can be included on the exterior of the package such that pulling on the tabs opens the access devices to facilitate communication between the compartments and their respective contents.

## Claims

### Claim 1

A content mixing package, comprising:
a first compartment adapted to hold first contents;
a second compartment adapted to hold second contents; and
at least one access device disposed between the first and second compartments such that a pulling force on a portion of the package selectively opens the at least one access device to enable communication of the first and second contents.

### Claim 2 (depends on 1)

The package of claim 1, wherein the at least one access device includes first and second access devices.

### Claim 3 (depends on 2)

The package of claim 2, further including an initial mixing region provided intermediate the first and second access devices.

### Claim 4 (depends on 2)

The package of claim 2, wherein at least one of the first and second access devices includes a zipper device.

### Claim 5 (depends on 1)

The package of claim 1, wherein the at least one access device includes a zipper device.

### Claim 6 (depends on 5)

The package of claim 5, wherein the zipper device includes opposing interlocking members.

### Claim 7 (depends on 1)

The package of claim 1, further including at least one external member provided proximate the at least one access device such that pulling on the at least one external member opens the at least one access device.

### Claim 8 (depends on 1)

The package of claim 1, wherein the at least one access device is a generally C-shaped film member.

### Claim 9 (depends on 1)

The package of claim 1, further including two external members provided proximate the at least one access device such that pulling on the two external members opens the at least one access device.

### Claim 10

A content mixing package, comprising:
a first flexible panel portion having an external surface and an internal surface;
a second flexible panel portion having an external surface and an internal surface;
a first compartment defined at least by the first and second flexible panel portions and adapted to hold first contents;
a second compartment defined at least by the first and second flexible panel portions and adapted to hold second contents distinct from the first compartment; and
at least one access device operably disposed to the internal surface of the first flexible panel portion and the internal surface of the second flexible panel portion between the first and second compartments such that opening the at least one access device enables communication of the first and second contents.

### Claim 11 (depends on 10)

The package of claim 10, wherein the at least one access device includes first and second access devices.

### Claim 12 (depends on 11)

The package of claim 11, further including an initial mixing region provided intermediate the first and second access devices.

### Claim 13 (depends on 11)

The package of claim 11, wherein at least one of the first and second access device includes a zipper device.

### Claim 14 (depends on 10)

The package of claim 10, wherein the at least one access device includes a zipper device.

### Claim 15 (depends on 14)

The package of claim 14, wherein the zipper device includes opposing interlocking members.

### Claim 16 (depends on 10)

The package of claim 10, further including at least one external member provided proximate the at least one access device extending from the external surface of the first flexible panel portion such that pulling on the at least one external member opens the at least one access device.

### Claim 17 (depends on 10)

The package of claim 10, wherein the at least one access device is a generally C-shaped film member, with a first portion of the film member peel sealed to the internal surface of the first panel portion and a second portion of the film member peel sealed to the internal surface of the second panel portion.

### Claim 18 (depends on 10)

The package of claim 10, further including two external members provided proximate the at least one access device such that pulling on the two external members opens the at least one access device.

### Claim 19 (depends on 10)

The package of claim 10, wherein the at least one access device includes a first flange disposed to the internal surface of the first flexible panel portion and a second flange disposed to the internal surface of the second flexible panel portion.

### Claim 20 (depends on 10)

The package of claim 10, wherein the at least one access device provides a substantially leak proof closure portion.
