Guide Intended for Hand Application
Lyallpur Metals Pvt Ltd is a versatile vacuum holding metal closure manufacturer. Whilst the bulk of Twist off caps are applied by the machine, some of the customers use hands to seal it. While hand capping, particular care must be taken as follows;
Following guidelines should be observed;
a) Filling – In order to allow the space to create vacuum, do not fill the jar / bottles to within 5% of the overflow or approximately 10mm from the rim or top.
b) Capping – pre heat (upto 60c) the cap if possible preferably if cold fill. Do not overheat the cap. This will soften the cap seal which will take the pressure of the lugs and make better seal. Apply cap fingers, not full hands, tight taking care not to cross the thread and ensuring cap lugs are engaged in the glass thread. Once finger tight, apply torque ( pressure) by ¼ to ½ of an inch. This will seal the cap.
The amount of torque applied is the most important part of twist off cap application as this can be a difference between achieving good vacuum ( sealed) and a loss of vacuum ( leakages) which can lead to mould, caps coming off if subjected to a shock.
Please remember this is not a screw cap and must not be over tightened.
Method to check if your cap is positioned right.
Make sure the distance between the glass mould line and left side of the lug cap be between ¼” or +- 7mm.
Make a visual check on the depression in the centre of the cap which should be concave. A good vacuum will pull down the centre of the cap.
No vacuum will appear a convex in the centre of the cap.
