Abstract

A retail bag-in-box transparent package having a flovvable product contained in a bag which is contained in a polymeric box where the box has (i) a flat bottom panel, an opposing top panel, and a self-supporting, upstanding, at least partially transparent wail connecting the bottom and top panels, and (ii) an access port through the box adapted for providing communication means for removing product from the bag, which is a flexible thermoplastic bag (capacity ≤1 liter (1000 ml)) attached to an interior surface of the box proximate the access port, where at least a portion of the bag has a transparent wall overlapping the transparent box portion to provide visual access to the product.

First claim

What is claimed is:

1. A retail bag-in-box package comprising:
a flowable product, a bag, and a box; said product contained in said bag which is contained in said box; wherein
(a) said box is plastic and has (i) a bottom panel, an opposing top panel, and a self-supporting upstanding wall connecting said bottom and top panels wherein at least a portion of said wall is transparent, and (ii) an access port through said top panel adapted for providing communication means for removing said product from said bag;
(b) said bag is made from a flexible thermoplastic film, hermetically sealed to itself, and containing said product with a bag volume capacity ≤1 liter (1000 ml), said bag attached to an interior surface of said box proximate said access port, wherein said bag is attached by adhesive, heat sealing, ultrasonic sealing, or radio frequency sealing, and wherein at least a portion of said bag has a transparent wall which overlaps said transparent portion of said box wall to provide visual access to a product contained within said bag, and
(c) said flowable product comprises a liquid; and
wherein said box wall has a Gurley stiffness of at least 1000 milligrams force and wherein said bag film has a Gurley stiffness of less than 50 milligrams force.

2. A retail bag-in-box package, as defined in claim 1 , wherein said bag has from 1 to 15 layers.

3. A retail bag-in-box package, as defined in claim 1 , wherein said bag has a WVTR of less than 0.5 g/100in 2 /24 hours at 100° F. (38° C.), 90% Relative humidity (R.H.), and 1 atmosphere.

4. A retail bag-in-box package, as defined in claim 1 , wherein said bag comprises at least five layers including a heat sealable layer, and a layer of EVOH.

5. A retail bag-in-box package, as defined in claim 1 , wherein said bag has an O 2 TR value of less than or equal to 10 cm 3 /100in 2 /24 hours at 1 atmosphere, 23° C. and 0% RH.

6. A retail bag-in-box package, as defined in claim 1 , wherein at least one of said bag and box comprises an ultraviolet light blocking material.

7. A retail bag-in-box package, as defined in claim 1 , wherein said box has intersecting walls with soft crease score lines, whereby whitened fold areas are avoided.

8. A retail bag-in-box package, as defined in claim 1 , wherein said bag and said box each have a haze value of less than 50%.

9. A retail bag-in-box package, as defined in claim 1 , wherein said bag and said box each has a portion of said transparent bag wall and box wall having a clarity of at least 50%.

10. A retail bag-in-box package, as defined in claim 1 , wherein said bag and said box each has a portion of said transparent bag wall and box wall having a clarity of at least 75%.

11. A retail bag-in-box package, as defined in claim 1 , wherein said transparent bag wall and box wall has a clarity of at least 90%.

12. A retail bag-in-box package, as defined in claim 1 , wherein said box comprises polyester, polyvinyl chloride, polypropylene, polystyrene, or nylon.

13. A retail bag-in-box package, as defined in claim 1 , wherein said bag further comprises communication means selected from a rigid straw, a pump, a tap, a valve, a sprayer, a flip top closure, a twist screw cap, a sport cap, a dispensing cap, and a snap cap hingedly covering a tubular opening.

14. A retail bag-in-box package, as defined in claim 1 , wherein said bag further comprises communication means selected from the group of fitments comprising a pump, a tap, a valve, a snap cap hinged covered tubular opening and said fitment is sealed to said bag; and said box access port is an opening through which said fitment projects.

15. A retail bag-in-box package, as defined in claim 1 , wherein said bag has a volume capacity of ≤500 ml.

16. A retail bag-in-box package, as defined in claim 1 , wherein said box wall has a thickness of at least 8 mil.

17. A retail bag-in-box package, as defined in claim 1 , wherein said bag film has a thickness ≤5 mil.

18. A retail bag-in-box package comprising:
a flowable product, a bag, and a box; said product contained in said bag which is contained in said box; wherein
(a) said box is plastic and has (i) a bottom panel, an opposing top panel, and a self-supporting upstanding wall connecting said bottom and top panels wherein at least a portion of said wall is transparent, and (ii) an access port through said box adapted for providing communication means for removing said product from said bag; and
(b) said bag is made from a flexible thermoplastic film, hermetically sealed to itself, and containing said product, said bag attached to an interior surface of said box proximate said access port, wherein said bag is attached by adhesive, and wherein said adhesive does not extend over said access port; and
wherein said box wall has a Gurley stiffness of at least 1000 milligrams force and wherein said bag film has a Gurley stiffness of less than 50 milligrams force.
