Abstract

A resealable blister package is described that includes a receiving member and a peelable lidding member. The receiving member has a cavity that can hold items, such as consumer products, and the peelable lidding member can be attached to a peripheral portion of the receiving member to seal the items within the cavity. The peelable lidding member includes a first film layer and a second film layer that are laminated via an adhesive layer. The blister package is designed to be opened to provide access to the cavity and the items therein by peeling the peelable lidding member away from the receiving member. The peelable lidding member can be resealed to the receiving member by bringing the lidding member back into contact with exposed portions of the adhesive layer remaining on the peripheral portion of the receiving member.

First claim

What is claimed is:

1. A blister package comprising:
a receiving member defining a cavity configured to hold an item therein and a peripheral portion at least partially surrounding the cavity, wherein the receiving member comprises a thermoformable material; and
a peelable lidding member attached to the peripheral portion of the receiving member and configured to cover the cavity and retain the item therein, the lidding member comprising:
a first film layer comprising a heat sealable polyester material configured to be attached to the peripheral portion of the receiving member, and
a second film layer comprising a metallized polyester material laminated to the first film layer via an adhesive layer,

wherein the blister package is configured to be opened to provide access to the cavity and the item therein by peeling the peelable lidding member away from the receiving member,
wherein a first portion of the second film layer is configured to remain adhered to the first film layer in a location corresponding to the cavity, such that the first film layer is removed with the first portion from the location corresponding to the cavity when the peelable lidding member is peeled away from the receiving member so as to provide access to the item therein,
wherein a second portion of the second film layer is configured to be separated from the adhesive layer in a location corresponding to at least part of the peripheral portion as the blister package is opened, with the adhesive layer remaining on the first film layer, such that the peelable lidding member is resealable to the receiving member when the second portion of the second film layer is moved into contact with a corresponding exposed portion of the adhesive layer,
wherein a series of cut lines are arranged around the edges of the cavity and through at least a thickness of the first film layer such that the cut lines form a closed continuous area along the perimeter of the cavity defining a portion of the first film layer that is configured to remain adhered to the second film layer when the peelable lidding member is peeled away from the receiving member, and wherein the adhesive layer in a hang tab region of the package comprises a permanent adhesive, and
wherein the package further comprises a transverse cut line formed through the receiving member, and a series of parallel transverse cut lines formed through the lidding member, such that the transverse cut line formed through the receiving member is aligned with one of series of cut lines formed through the lidding member to create a break tab.

2. The blister package of claim 1 , wherein the receiving member comprises glycol-modified polyethylene terephthalate (PETG).

3. The blister package of claim 1 , wherein the first film layer comprises polyethylene terephthalate (PET).

4. The blister package of claim 1 , wherein the adhesive layer in other regions of the package comprises pressure sensitive adhesive.

5. The blister package of claim 1 , wherein an ink layer is disposed between the first film layer and the adhesive layer.

6. The blister package of claim 1 , wherein the second film layer comprises metallized polyethylene terephthalate (mPET), and wherein a first ink layer is disposed between the first film layer and the second film layer, and a second ink layer is disposed on an outer surface of the second film layer, such that the first ink layer may only be seen from one side of the package and the second ink layer may only be seen from an opposite side of the package.
