Abstract

A tamper evident package comprises a blister assembly defining at least one cavity, the opening of the at least one cavity being at least partially closed by a membrane. A sleeve housing the blister assembly is provided, the sleeve having a top side and a bottom side, the bottom side having a contact window that is aligned with the cavity. In addition, a package integrity feature is applied to the bottom side and covers the contact window. The package integrity feature is further applied to the membrane covering the cavity through the contact window.

First claim

What is claimed is:

1. A tamper evident blister package comprising:
a blister assembly defining at least one cavity, the opening of the at least one cavity being at least partially closed by a membrane;
a sleeve housing the blister assembly, the sleeve having a top side and a bottom side, the bottom side having a contact window that is aligned with the cavity;
a package integrity feature applied to the bottom side and covering the contact window; and
wherein the package integrity feature is further applied to the membrane covering the cavity through the contact window.

2. The package of claim 1 , wherein the package integrity feature is a pressure sensitive adhesive.

3. The package of claim 1 , wherein the package integrity feature prevents lateral removal of the blister assembly from the sleeve.

4. The package of claim 1 , wherein the package integrity feature is perforated and circumferentially outlines the contact window of the sleeve.

5. The package of claim 1 , further comprising an indicia of origin or manufacture printed over the package integrity feature, and the contact window.

6. The package of claim 1 , wherein the cavity includes a pellet and the sleeve further comprises an access window aligned with the cavity on the top side of the sleeve for allowing pressure dispensing of the pellet through the contact window.

7. The package of claim 6 , wherein the contact window is sufficiently sized to allow the pellet to pass therethrough.

8. A tamper evident blister package comprising:
a blister assembly defining at least one cavity for housing a pellet;
a sleeve housing the blister assembly, the sleeve including a bottom side defining a contact window that is vertically aligned with the cavity;
a package integrity feature applied over the contact window; and
wherein, through the contact window, the package integrity feature is further applied to an area of the blister assembly defining the cavity.

9. The package of claim 8 , wherein the package integrity feature is a pressure sensitive adhesive.

10. The package of claim 8 , wherein the package integrity feature prevents lateral removal of the blister assembly from the sleeve.

11. The package of claim 8 , wherein the package integrity feature is perforated and circumferentially outlines the contact window of the sleeve.

12. The package of claim 8 , further comprising an indicia of origin or manufacture printed over the package integrity feature, and the contact window.

13. The package of claim 8 , wherein the sleeve further comprises an access window aligned with the cavity on the top side of the sleeve for allowing pressure dispensing of the pellet through the contact window.

14. A method of manufacturing a tamper evident blister package comprising:
providing a blister assembly defining at least one cavity, the opening of the at least one cavity being at least partially closed by a membrane;
housing the blister assembly in a sleeve, the sleeve having a top side and a bottom side, the bottom side having a contact window that is aligned with the cavity;
applying a package integrity feature applied to the bottom side and covering the contact window; and
applying the package integrity feature to the membrane covering the cavity through the contact window.

15. The method of claim 14 , wherein the package integrity feature is a pressure sensitive adhesive.

16. The method of claim 14 , wherein the package integrity feature prevents lateral removal of the blister assembly from the sleeve.

17. The method of claim 14 , further comprising the act of perforating the package integrity feature and circumferentially outlining the contact window of the sleeve.

18. The method of claim 14 , further comprising the act of printing an indicia or origin or manufacture over the package integrity feature, and the contact window.

19. A method of manufacturing a tamper evident blister package comprising:
providing a blister assembly defining at least one cavity for housing a pellet;
housing the blister assembly in a sleeve, the sleeve including a bottom side defining a contact window that is vertically aligned with the cavity;
applying a package integrity feature over the contact window; and
wherein, through the contact window, the package integrity feature is further applied to an area of the blister assembly defining the cavity.

20. The method of claim 19 , wherein the package integrity feature is a pressure sensitive adhesive.

21. The method of claim 19 , wherein the package integrity feature prevents lateral removal of the blister assembly from the sleeve.

22. The method of claim 19 , further comprising the act of perforating the package integrity feature and circumferentially outlining the contact window of the sleeve.

23. The method of claim 19 , further comprising the act of printing an indicia or origin or manufacture over the package integrity feature, and the contact window.
