Test System tests child-resistant closures.
Share:
Press Release Summary:
Able to simultaneously measure downward force and release torque applied to closure, Child-Resistant Closure Tester is suitable for identifying designs of closures which present insufficient challenge to child, or too great physical challenge to elderly or infirm adult. Operator may apply top-load of up to 110 lbf and torque of up to 90 lbf in. Peak values can be downloaded via RS232 output to printers, dataloggers, or PCs for archiving and analysis.
Original Press Release:
New System Launched for Testing Child-resistant Closures
Mecmesin has launched a new testing system which will be of considerable interest to the packaging industry.
A child-resistant package can be described as one sealed in such a manner that it can be opened only by a person with a combination of dexterity, co-ordination, strength and experience well within the capabilities of a 'legitimate user', but beyond the capacity of a small child. One example of such a package is a container with a 'Type 1A' closure (see ASTM D3472-97), i.e. a screw cap which requires a simultaneous pushing and twisting action before opening is possible. Closures of this type are in widespread use for protecting children from: paints, solvents, thinners, household chemicals, adhesives, cleaning fluids, garden chemicals and particularly pharmaceuticals.
The Mecmesin child-resistant closure tester is able simultaneously to measure the downward force and the release torque applied to a closure. This makes it a particularly suitable instrument for identifying designs (or batches) of closures which either present an insufficient challenge to a child, or too great a physical challenge to an elderly or infirm adult.
An operator may apply to a closure both a top-load of up to 500N (110lbf) and a torque of up to 10N.m (90lbf.in). The CRC tester can also measure 'reverse-ratchet torque', i.e. the torque developed when rotating a closure in a counter-clockwise direction without any top-load being applied.
Peak values of force and torque can be downloaded via RS232 output to printers, dataloggers or PCs for subsequent archiving and analysis.
