Introduction to the open force test method of the canned bottle cap of jam

Jam canned cap opening force test method introduces the jam bottle mouth is mostly screw cap packaging, that is, need to manually rotate and unscrew the cap before eating, if the cap seal is too tight, it is not easy for the edible person to open, if the bottle cap seal is not tight, there will be bottle leakage caused by the quality of the jam shelf life and other problems.
how to solve the problem of screw cap bottled jam with suitable cap sealing and good cap opening force, effective testing methods are required to verify.
This test uses Labthink Languang NJY-20 torque meter to test the torque value of the sample, through the size of the torque to assess whether the opening force of the jam cap can ensure easy to open and not leak, for the jam production industry to provide a technical reference.
NJY-20 torque meter is suitable for bottled and hose-packed food, cosmetics, pharmaceutical (threaded connection) cap locking, open torque value testing.
such as canned bottles, hand creams, beverage bottles, medicine bottles, etc.
can also be extended for thermostats, thermostats (threaded connections), nuts and bolt locking, open torque value testing.
equipment testing principle: the use of the configuration of torsional angle phase differential sensor, the use of strain bridge detection means to achieve the sample test elastic shaft twisted electrical signal monitoring, so as to test the cap opening torque or locking value size.
, the domestic test cap opening torque performance mainly refers to ASTM D2063 "measuring the packaging screw cap torque hold test method."
the test process is as follows: (1) In the laboratory standard environment, the condition-adjusted jam glass bottle sample is placed on the instrument fixture, clamped.
(2) set the instrument mode to "On Torque" and click to start the test.
(3) place your hand at the cap and unscrew it, at which point the instrument automatically detects the on torque value.
(4) follow the steps above and test the remaining 2 samples in turn.
