Abstract

A sealing system positionable to cover an opening in a package body covering removable articles includes a base material and a resealable label flap. The base material is permanently attached to the package body and formed with a die cut line surrounding the opening in the package body and defines a movable blank. The base material has a back surface provided with a permanent adhesive provided with a deadened area covering the blank and extending beyond the die cut lie. The resealable label flap is positioned on the base material to cover the opening in the packaged body and the die cut line. The resealable flap has a back surface provided with a resealable adhesive that permits repeated application and removal of the label flap relative to the base material.

Claims

1. A sealing assembly covering an opening provided in a package body containing removable articles, the sealing assembly comprising:

a base material separate from and fixedly attached to a portion of the package body in covering relationship to the opening and having a cut line defining a blank completely removable from the base material to define a hole aligned with the opening in the package body, the blank covering the opening in the package body, the base material having a back surface provided with a first adhesive permanently holding the base material to the package body and preventing separation of the base material from the package body should a pulling force be applied to the base material, the base material including a deadened area covering the entire blank and extending beyond the cut line to prevent the attachment of the blank to the package body; and

a resealable label flap engageable with an upper surface of the base material and completely overlying at least the cut line, the resealable flap having a back surface provided directly thereon with a second adhesive that permits repeated application of the label flap directly upon the upper surface of the base material, and permits repeated removal of the label flap directly from the upper surface of the base material, wherein one end of the label flap back surface is provided with a third adhesive preventing the complete removal of the label flap from the base material, the third adhesive having an adhesive strength stronger than the second adhesive.

2. The sealing assembly of claim 1, wherein the resealable label flap forms a liquid and airtight seal with the base material.

3. The sealing assembly of claim 1, wherein the deadened area is covered with a non-adhesive material.

4. A resealable package comprising:

a package body having an opening provided therein for accessing a plurality of removable articles contained therein;

a base material separate from and fixedly attached to a portion of the package body in covering relationship to the opening and having a cut line defining a blank completely removable from the base material to define a hole aligned with the opening in the package body, the blank covering the opening in the package body, the base material having a back surface provided with a first adhesive permanently holding the base material to the package body and preventing separation of the base material from the package body should a pulling force be applied to the base material, the base material including a deadened area covering the entire blank and extending beyond the cut line to prevent the attachment of the blank to the package body; and

a resealable label flap positioned on a top surface of the base material to cover at least the opening in the package body and the cut line, the resealable flap having a back surface provided directly thereon with a second adhesive that permits repeated application and removal of the label flap relative to the base material,

whereby, upon applying a pulling force to effect removal of the label flap from the base material, the blank remains completely attached to the back surface of the label flap and the opening in the package body is exposed to enable removal of the articles in the package, after which, the label flap is resealed against the base material so that the blank covers the opening and the second adhesive creates an impermeable fluid-tight seal around the opening, and

wherein one end of the label flap back surface includes a third adhesive preventing complete removal of the label flap from the base material, the third adhesive having an adhesive strength stronger than the second adhesive.

5. The resealable package of claim 4, wherein the package body is comprised of a material having a top surface to which the base material is attached, the top surface surrounding the opening in the package body and preventing repeated attachment and reattachment of the label flap relative to the package body.

6. The resealable package of claim 4, wherein the deadened area is covered with a non-adhesive material.

7. The resealable package of claim 4, wherein a deadened strip is created between a periphery of the deadened area and the cut line.

8. The resealable package of claim 7, wherein the deadened strip aids in separating the blank from the base material by reducing the pulling force required on the label flap around the cut line.

9. The resealable package of claim 4, wherein the package body includes a pair of flaps closable along a seam extending through the opening in the package body.

10. The resealable package of claim 9, wherein the base material is attached over the seam such that the deadened area is centered over and covers the opening in the package body.
