Reading bottle drawings and understanding the associated terminology can be a complex task. At COMPAX, we’re here to help you unravel the standard codes commonly used in bottle manufacturing. It’s essential to remember that while some of the letters may appear the same, they might refer to different measurements for closures rather than the bottle itself. Let’s dive into the key terms and their meanings:
“A” – Diameter of the Lip Undercut #
“A” represents the diameter of the lip undercut. This measurement is crucial for understanding how the bottle’s lip is designed, which is essential for proper sealing and compatibility with closures.
“B” – Diameter of the Neck Bead #
“B” signifies the diameter of the neck bead. The neck bead is a structural feature that provides stability and reinforcement to the bottle’s neck, ensuring it can support the closure and its contents.
“E” – Diameter of the Wall at the Base of the Thread #
“E” indicates the diameter of the wall at the base of the thread. This measurement plays a vital role in determining the bottle’s thread depth, which is essential for the secure attachment of closures.
“H” – Height of the Finish #
“H” represents the height or vertical distance from the top of the finish to either the bead or the shoulder of the bottle. Understanding this measurement helps assess the overall dimensions of the bottle’s finish.
“I” – Inner Diameter #
“I” corresponds to the inner diameter, specifically the minimum opening through the finish and the neck. This measurement is crucial for ensuring that the bottle’s neck is compatible with the desired closure.
“N” – Thickness of the Lip for a Snap Fit Neck #
“N” signifies the thickness of the lip, particularly for bottles with snap-fit necks. This measurement helps determine the structural integrity and sealing capabilities of the bottle.
“T” – Outer Diameter of the Thread #
“T” denotes the outer diameter of the thread. Thread dimensions are essential for compatibility with closures, ensuring a secure and tight seal.
“W” – Height of the Bead #
“W” represents the height of the bead, a structural feature that contributes to the bottle’s strength and stability.
“Z” – Width of the Land #
“Z” refers to the width of the land, which is the top sealing surface. Understanding this measurement is vital for selecting closures that can properly seal the bottle.
By familiarizing yourself with these key terms and their meanings, you’ll be better equipped to interpret bottle drawings accurately.
