Storage of Bottles and Closures.

All Bottles, Jars and Closures must be stored in a cool dry location out of direct sunlight.

PET Bottles And Jars.

With respect to PET Bottles and Jars - they are particularly susceptible to heat and sunlight and particular care should be taken. PET bottles and Jars exhibit particular tell tale faults if stored incorrectly.

Selected SPI Neck Finish Specifications

Standard dimensions derived from GPI/SPI 400 Series, 410 Series and 415 Series Tables.

 

A container's neck finish holds the closure with protruding threads. A container and its corresponding cap must have matching finishes. For example, a 24/410 bottle will only accept a 24/410 closure.

 

Screw thread or continuous thread closure sizes are expressed with two numbers separated by a hyphen or slash. The first number refers to the millimeter diameter measured across the inside of the cap's opening or the outside of the bottle's threads. The second number refers to the thread style, "GPI" or "SPI" finish. The Glass Packaging Institute (GPI) and Society of the Plastics Industry (SPI) are responsible for establishing uniform standards for glass and plastic container neck finishes. The closure industry does not necessarily adhere to the same standards, so it is best practice to purchase containers and caps from the same supplier when possible.

Common GPI / SPI Neck Finishes

 

cap dimentions

1 Thread turn -- 1.5 Thread turns -- 2 Thread turns

 

Neck

 

“H” Dimension: The height of the neck finish. Measured from the top of the neck to the point where the diameter, “T”, extends down and intersects the shoulder.
“S” Dimension: Measured from the top of the finish to the top edge of the first thread. The “S” dimension is the key factor in determining the orientation of the closure to the bottle and the amount of thread engagement between the bottle and cap.
“I” Dimension: The inner diameter of the bottle neck. Specifications require a minimum “I” to allow sufficient clearance for filling tubes. Liner less closures, with a plug or land seal, and dispensing plugs and fitments require a controlled “I” for a proper fit.
“T” Dimension: The outside diameter of the thread. The tolerance of the “T” dimension determines the mate between bottle and closure.
“E” Dimension: The minor diameter measured across the root of the threads.
