Abstract

An easy-open and reclosable package includes a pouch including a discrete laminate including a base strip, a panel section, and a die cut defining a die cut segment; a first and second anchor seal; the base strip including a sealing segment, backing segment, and intermediate layer including a pressure sensitive adhesive; and a product disposed in the pouch. The die cut segment is so arranged that when the package is opened, the sealing segment is partially removed from the base strip, the pressure sensitive adhesive is partially exposed, and the package can thereafter be reclosed by adhering any of the first side panel, second side panel, and panel section to the pressure sensitive adhesive. Methods of making the package, and a pouch, are also disclosed.

First claim

What is claimed is:

1. An easy-open and reclosable package comprising:
a) a pouch comprising
i) a first and second side panel each comprising an outer and inner surface, a first and second side edge, and a first and second end, the first and second side panels joined together along their respective first and second side edges with a seal;
ii) a first end;
iii) a second end defined by the second ends of the first and second side panels respectively; and
iv) a discrete laminate having a first and second end, the discrete laminate comprising
(a) a base strip comprising a first and second surface, a first and second side edge, a first and second end, a sealing segment, a backing segment, and an intermediate layer disposed between the sealing and backing segments and comprising a pressure sensitive adhesive, the first and second surfaces of the base strip comprising a sealant,
(b) a panel section comprising an outer and inner surface, a first and second side edge, and a first and second end, the inner surface comprising a sealant, and
(c) a die cut disposed in the panel section, the die cut defining a closed loop die cut segment;

v) a first anchor seal whereby a first portion of the first surface of the base strip is anchored to the inner surface of the panel section at a first location on the panel section;
vi) a second anchor seal whereby the discrete laminate is anchored to the first side panel;
vii) the first end of the panel section joined to the second side panel;
viii) the panel section and the second side panel joined together along their respective first and second side edges with a seal;
ix) the first end of the panel section extending beyond the first end of the base strip; and
x) the closed loop die cut segment being spaced from the first and second ends of the package, and so arranged with respect to the base strip that when the package is opened, by removing the closed loop die cut segment, the sealing segment is at least partially removed from the base strip at the first anchor seal, the intermediate layer comprising the pressure sensitive adhesive is at least partially exposed at the first anchor seal, and the package can thereafter be reclosed by adhering any of the first side panel, second side panel, and panel section to the pressure sensitive adhesive; and

b) a product disposed in the pouch;
wherein the second surface of the base strip is sealed to the inner surface of the second side panel with an easy-open seal.

2. The easy-open and reclosable package of claim 1 wherein the die cut segment is partially underlain by the base strip.

3. The easy-open and reclosable package of claim 1 wherein the die cut segment includes a first portion wherein the die cut extends partially through the panel section, and a second portion wherein the die cut extends entirely through the panel section.

4. The easy-open and reclosable package of claim 1 wherein the outer surface of the panel section is anchored to the inner surface of the first side panel.

5. The easy-open and reclosable package of claim 1 wherein the sealing segment comprises a single layer.

6. The easy-open and reclosable package of claim 1 wherein the backing segment comprises a single layer.

7. An easy-open and reclosable package comprising:
a) a pouch comprising
i) a first and second side panel each comprising an outer and inner surface, a first and second side edge, and a first and second end, the first and second side panels joined together along their respective first and second side edges with a seal;
ii) a first end;
iii) a second end defined by the second ends of the first and second side panels respectively; and
iv) a discrete laminate having a first and second end, the discrete laminate comprising
(a) a base strip comprising a first and second surface, a first and second side edge, a first and second end, a sealing segment, a backing segment, and an intermediate layer disposed between the sealing and backing segments and comprising a pressure sensitive adhesive, the first and second surfaces of the base strip comprising a sealant, wherein the second surface of the base strip is sealed to the inner surface of the second side panel with an easy-open seal,
(b) a panel section comprising an outer and inner surface, a first and second side edge, and a first and second end, the inner surface comprising a sealant, and
(c) a die cut disposed in the panel section, the die cut defining a die cut segment;

v) a first anchor seal whereby a first portion of the first surface of the base strip is anchored to the inner surface of the panel section at a first location on the panel section;
vi) a second anchor seal whereby the discrete laminate is anchored to the first side panel;
vii) the first end of the panel section joined to the second side panel;
viii) the panel section and the second side panel joined together along their respective first and second side edges with a seal;
ix) the first end of the panel section extends beyond the first end of the base strip; and
x) the die cut segment is so arranged with respect to the base strip that when the package is opened, the sealing segment is partially removed from the base strip at the first anchor seal, the intermediate layer comprising the pressure sensitive adhesive is partially exposed at the first anchor seal, and the package can thereafter be reclosed by adhering any of the first side panel, second side panel, and panel section to the pressure sensitive adhesive; and

b) a product disposed in the pouch.

8. The easy-open and reclosable package of claim 7 wherein the die cut segment is partially underlain by the base strip.

9. The easy-open and reclosable package of claim 7 wherein the die cut segment includes a first portion wherein the die cut extends partially through the panel section, and a second portion wherein the die cut extends entirely through the panel section.

10. The easy-open and reclosable package of claim 7 wherein the outer surface of the panel section is anchored to the inner surface of the first side panel.

11. The easy-open and reclosable package of claim 7 wherein the sealing segment comprises a single layer.

12. The easy-open and reclosable package of claim 7 wherein the backing segment comprises a single layer.

13. The easy-open and reclosable package of claim 7 wherein the first surface of the base strip is anchored to the inner surface of the first side panel.
