Abstract

A testing system is provided for an article wrapped with an overwrap. The testing system includes first and second receptacle portions cooperating to define a test receptacle having a test fixture therein. The test receptacle is configured to receive the wrapped article. The test fixture is configured to form a seal with the test fixture about a perimeter thereof and to draw a portion of the overwrap away from the article in response to a suction applied in association with the test fixture. A piercing device is configured to form an orifice in the overwrap, within the perimeter, and a fluid between the overwrap and the article, through the orifice, from a fluid source. A pressure and/or a fluid flow change within the test receptacle, externally to the overwrap, is measured with a measuring device to determine whether there is leakage in the overwrap. An associated method is also provided.

4. The testing system of claim 1, wherein the first receptacle portion and the second receptacle portion are configured to be complementarily engaged such that the test receptacle thereby is configured to receive and enclose a cigarette package wrapped with the overwrap.

5. The testing system of claim 4, further comprising a cigarette package hopper configured to deliver a cigarette package wrapped with the overwrap, which forms an overwrap wrapped cigarette package, to the test receptacle.

6. The testing system of claim 4, further comprising a securing arrangement operably engaged with the first receptacle portion or the second receptacle portion and configured to secure the overwrap wrapped cigarette package in a testing position within the test receptacle.

7. The testing system of claim 1, wherein the fluid source operably engaged with the second receptacle portion is configured to direct the fluid through the inlet port of the second receptacle portion, through an inlet port defined by the test fixture and in fluid communication with the inlet port of the second receptacle portion, and into the overwrap through the orifice.

8. The testing system of claim 1, wherein the fluid source operably engaged with the second receptacle portion is configured to direct the fluid through the inlet port of the second receptacle portion, through a piercing port defined by the test fixture and in fluid communication with the inlet port of the second receptacle portion, and into the overwrap through the orifice.

9. The testing system of claim 1, wherein the piercing device operably engaged with the second receptacle portion is configured to operably engage a piercing port defined by the test fixture, and is cooperable therewith to form the orifice in the portion of the overwrap within the perimeter of the test fixture.

10. The testing system of claim 1, wherein the piercing device operably engaged with the second receptacle portion is configured to operably engage the inlet port defined by the test fixture, and is cooperable therewith to form the orifice in the portion of the overwrap within the perimeter of the test fixture.

11. The testing system of claim 1, wherein the second receptacle portion further comprises an end wall and a side wall cooperating to define a test fixture cavity, the test fixture cavity being configured to receive the test fixture therein such that the test fixture is spaced apart from the side wall so as to define a seal channel therebetween.

12. The testing system of claim 11, wherein the test fixture includes a first surface disposed adjacent to the end wall when the test fixture is received in the test fixture cavity, the first surface defining a suction channel extending therealong, the suction channel being further configured to be in fluid communication between the outlet port of the second receptacle portion and the seal channel such that suction applied through the outlet port is realized in the seal channel to form the seal with the overwrap about the perimeter of the test fixture.

13. A method for testing an article wrapped with an overwrap for leakage in the overwrap, the method comprising:

receiving and enclosing the article wrapped with the overwrap that forms an overwrap wrapped article within a test receptacle defined by a first receptacle portion complementarily engaged with a second receptacle portion;

applying a suction through an outlet port defined by the second receptacle portion so as to form a seal between a test fixture disposed within the test receptacle and the overwrap about a perimeter defined by the test fixture, the test fixture being operably engaged with the second receptacle portion and being in communication with an inlet port and the outlet port defined by the second receptacle portion, and so as to draw a portion of the overwrap away from the article disposed within the test receptacle and into contact with the test fixture;

forming an orifice in the portion of the overwrap, within the perimeter of the test fixture and drawn away from the article, with a piercing device operably engaged with the second receptacle portion;

directing a fluid into the overwrap, between the overwrap and the article, through the orifice, from a fluid source operably engaged with the second receptacle portion; and
