Abstract

A package has a carton with a liner with a recloseable closure. The package is shippable as a relatively flat carton blank.

Claims (78)

(iii) a mated recloseable closure attached at or adjacent to the first terminal end of only the first liner wall and being free from attachment to the second liner wall;

(iv) the front panel and first side panel have a bendable corner A therebetween; the front panel and the second side panel have a bendable corner B therebetween; the rear panel and the second side panel have a bendable corner C therebetween; the rear panel and the first side panel have a bendable corner D therebetween; bendable corners B and D being at opposite ends of the blank arrangement, with bendable corner C nearer to B than D; and with bendable corner A nearer D than B; and the mated recloseable closure being relatively straight and free of folds from adjacent bendable corner B extending at least partially toward bendable corner D;

(b) bending corners A, B, C, and D to form a rectangular tube with an open interior and an open top and bottom;

(d) providing filling material into the open interior; and

(e) attaching the mated recloseable closure to the second liner wall to close the first terminal end of the tubular liner.

12 . The method of claim 11 , further including:

after closing the first terminal end of the tubular liner, forming a closure at the top of the rectangular tube.

13 . The method of claim 11 , wherein the step of providing a relatively flat blank arrangement includes the mated recloseable closure being a recloseable zipper closure having male and female mating profiles.

14 . The method of claim 13 , wherein the recloseable zipper closure has a slider device attached thereto, constructed and arranged to close and open the zipper closure, as the slider device is moved along the zipper closure.

15 . The method of claim 11 , wherein the step of providing a relatively flat blank arrangement includes the mated recloseable closure is a hook and loop fastener.

16 . A method of using a recloseable package; the method comprising:

(a) providing a closed carton having a liner in an interior of the carton;

(b) opening an end of the carton to access the interior;

(d) closing the recloseable closure on the liner.

17 . The method of claim 16 , wherein the step of opening the recloseable closure includes opening a recloseable zipper closure.

18 . The method of claim 17 wherein the step of opening a recloseable zipper closure includes moving a slider device along the zipper closure.

19 . The method of claim 16 , wherein the step of opening the recloseable closure includes opening a recloseable hook and loop closure.

20 . A package blank for a carton and liner; the package blank comprising:

(b) a tubular liner having an exterior surface and opposite liner interior surface; the exterior surface of the liner being attached to the interior surface of each of the front, rear, first side and second side panels; the tubular liner having a first terminal end and an opposite, second terminal end; the tubular liner having opposing first and second liner walls; and

(c) a mated recloseable closure attached at or adjacent to the first terminal end of the tubular liner, closing the first terminal end; the second terminal end being open.

21 . The package blank of claim 20 , wherein:

(a) the first side panel having a bendable foldline A dividing the first side panel between a first side panel first section and a first side panel second section;

(b) the second side panel having a bendable foldline B dividing the second side panel between a second side first panel section and a second side panel second section;
