Abstract

An easy-open and reclosable package includes a pouch including a discrete laminate including a tape including a base strip coated with a pressure sensitive adhesive, and a panel section having a die cut defining a die cut segment, the panel section adhered by the PSA to the base strip; the panel section anchored to a first side panel; the second surface of the base strip anchored to the inner surface of a second side panel; and a product in the pouch. The die cut segment is so arranged with respect to the pressure sensitive adhesive that when the package is opened, the package can be reclosed by adhering the pressure sensitive adhesive to the first side panel.

First claim

What is claimed is:

1. An easy-open and reclosable hermetic 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 tape comprising
(i) a base strip comprising a first and second surface, a first and second side edge, and a first and second end, at least one of the first and second surfaces of the base strip comprising a sealant, and
(ii) a pressure sensitive adhesive coated on at least a first portion of the first surface of the base strip,

(b) a panel section comprising an outer and inner surface, a first and second side edge, a first and second end, and a die cut; wherein
the at least first portion of the first surface of the base strip is adhered by the pressure sensitive adhesive to a first part of the inner surface of the panel section, the panel section is anchored to the first side panel, and the second surface of the base strip is anchored to the inner surface of the second side panel,
the first end of the panel section is joined to the second side panel,
the panel section and the second side panel are joined together along their respective first and second side edges with a seal, and
the die cut defines a primary die cut segment, wherein a first portion of the primary die cut segment is underlain by the pressure sensitive adhesive, and a second portion of the primary die cut segment is underlain by a clear area, the primary die cut segment so arranged with respect to the base strip that when the package is opened, by removing the primary die cut segment, at least a portion of the pressure sensitive adhesive is exposed, and the package can thereafter be reclosed by adhering the pressure sensitive adhesive to the first side panel; and wherein the discrete laminate is anchored to the first side panel; and

b) a product disposed in the pouch.

2. The easy-open and reclosable package of claim 1 wherein the first surface of the base strip comprises an easy-open sealant.

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

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

5. The easy-open and reclosable package of claim 1 wherein the primary die cut segment is spaced apart from a first and second side seal respectively.

6. The easy-open and reclosable package of claim 1 wherein a secondary die cut segment is disposed between the primary die cut segment and an end of the package, and is underlain at least in part by the pressure sensitive adhesive, the secondary die cut segment so arranged with respect to the base strip that when the secondary die cut segment is displaced or removed, at least a portion of the pressure sensitive adhesive is exposed.
