EN 16065:2011 – Packaging – Rigid plastic containers – PET finish 30/25 Low
1 Scope
This European Standard specifies the dimensions and requirements of the 30 mm low screw finish with three (3) thread starts for flat waters and non-carbonated beverages.
This finish can be used for aseptic filling and filling with introduction of nitrogen. The dimension (16,8) is the height in millimetres from the top of finish to the bottom of the support ledge.
This finish is designed to take a tamper evident plastic closure only. During first opening, the tamper evident band will separate from the closure shell and stay on a one way bottle neck or like bottles in the returnable market, the tamper evident band will tear but will remain connected to the closure shell.
2 Dimensions
2.1 The design and dimensions of the finish shall be as shown in Figure 1.
2.2 Dimensions of the 3 thread starts 120° apart.
180° of full depth thread per lead
R 6,25 thread lead-in
R 6,25 thread run-out
Lead: 9 mm (travel per turn)
2.3 General tolerance for others radii: ± 0,13 mm.
2.4 Weight on height 16,8 mm: 3,73 g (density = 1,335).
3 Requirements
The following requirements apply.
This finish is a top, side and inside seal finish. This finish shall be smooth and free of any defects that will contribute to leaks. Flash shall not exceed 0,13 mm per side, and shall not be continuous.
On the blown bottle, the control diameter C shall be free of any defects up to 4 mm down for the internal bore and across the sealing surface of the finish.
Requirements for good closure application on finish:
• 0,13 mm max. out-of-parallel sealing surface with neck support ledge is allowed;
• an offset or vertical mismatch of thread is not to exceed 0,10 mm at the mould seam.
Ø T dimension is not measured in the depressed area.
Variations in Ø E are to follow uniformly those of Ø T.
No overhang allowed at any point in 360° between Ø F and Ø G. A flash to 0,15 mm maximum step is allowable on one side only. Ø G does not exceed Ø E.
