Secure Seal Tester For Bottle Seal

June 15, 2012 - PRLog -- The Secure Seal Tester allows you to test thread and seal integrity on your glass or plastic carbonated beverage containers. The Secure Seal Tester has been designed to address the special needs of sealing carbonated beverages containers that use aluminum roll-on, twist crowns, or plastic caps. By detecting gas leakage, rather than liquid, the Secure Seal Tester gives more sensitive, accurate readings.

The Primary Function of Secure Seal Tester is to seal the container
•   lined closure
•   linerless closure

•   A LINED closure is one that has a paper, plastic, metal foil, plastic film or combination liner. Dispensing closures are sometimes lined and other types of usually unlined closures are sometimes lined for different reasons.

•   A LINERLESS closure which provides an effective seal because it has some sort of anti-leaking feature molded into the inside top of the cap against oxygen penetration and moisture evaporation with an inner annular member defining an annular outwardly directed sealing circumference which forms a line seal with the inner cylindrical surface of a container wall and an outer annular member defining an annular inwardly directed sealing circumference which seals against the outer cylindrical surface of a container wall.

This test method exists how well do they work together for measuring a variety of closure attributes of the closure/ bottle systems which are designed with many different styles and features:

•   Continuous Thread (CT) i.e. a regular screw cap with a continuous thread.

•   Child Resistant Closure (CRC) i.e. which may be of a single piece or two piece design. If a two piece CRC, it usually has a CT inner cap with the palm or pushes down and turns outer shell.

•   Snap Cap i.e. in PE milk bottles

•   Dispensing (water bottles, dish washing soaps) i.e. are those that via a pull/push, spout, twist, or flip top allow products to be dispensed. It is usually linerless closures with some sort of sealing mechanism such as: crabs claw, valve seal, land seal or some combination of the seals, but not always.

•   Hinged dispensing i.e. in ketchup bottles

•   Hybrid plastic threaded ring with metal insert i.e. in peanuts, sauces

Thus, the Secure Seal Test (SST) Closure/finish assemblies are cut from bottles or containers and pressurized to measures the ability of the closure/finish seal to hold pressure, providing a measure of how well the closure seals to the finish.
