Mecmesin performs compression test on tamper-evident ring for beverage industry manufacturer

Tamper-Evident Ring Test

The customer manufactures closures for the beverage industry. These include tamper-evident caps used on mineral waters and other soft drinks.

The company wished to perform a compression test on the tamper evident ring, which could measure the maximum force used to ‘push it off‘ the cap. As the tamper-evident closures are fitted onto bottles using a compressive action, this test would provide the company with valuable information relating to the correct application of force throughout production.

A MultiTest 1-d motorised test stand, rated to 1000 N, an AFG 500 N digital gauge and special accessory were supplied, by Mecmesin, to perform this test.

The special accessory comprises a tapered spigot (in varying diameters to accommodate different cap sizes), push tube, tube cap and cap base pillar. Together, this forms a simple solution, in which a compressive force is applied, to, in essence, ‘push off‘ the ring, thereby separating the tamper-evident element from the cap.

With a tamper-evident closure securely fitted onto the tapered spigot, the compression plate, fixed to the digital gauge, is lowered to a pre-defined distance, detaching the tamper-evident ring from the cap. The AFG records the peak force measurement and transmits the reading to a PC hosting the customers SPC monitoring software.

Using the constant speed of the Motorised Test Stand ensures optimum repeatability for the test helping the customer to check that their manufacturing practices are correct and product quality is being maintained.

- MultiTest 1-d motorised test stand rated to 1 kN (superseded by the MultiTest-dV series)
- Advanced Force Gauge (AFG) 500 N
- Special tamper-evident ring accessory
- Compression platen
- Emperor™ Lite data acquisition software

Cosmetic packaging pull-off test

A bench-top testing system was required to repeatably test the pull-off force on a variety of cosmetic containers. The system needed to allow a relatively high volume of containers to be tested with the minimum level of training required for users. Mecmesin's solution avoided the risk of damaging the loadcell by excessive torque on tightening the collet grip, and the lipstick barrel was first inserted in the grip and then connected to the gauge by a flexible chain-link.

Food packaging made from thermoformed plastics and intended for freezing, requires testing to ensure optimum functionality when closing and sealing the container. The closing effort of the lid is measured by using a motorised force tester controlled by software together with a custom-designed fixture to hold standard-sized ice cream tubs. In addition the ‘top-load’ crush strength of the container itself can also be tested on the same machine to guarantee it is rigid enough to avoid buckling and spillage when the lid is applied.

Mecmesin develops Combi Cork-i Extraction Tester for leading Scottish whisky

To improve the quality and storage of a premium product, the R&D team at a leading Scottish whisky maker needed to optimise the design of their bottle stoppers. They decided that the strength and performance of their reusable stoppers could be ensured by systematic testing of the characteristics of both portions of the stoppers. Working closely with the R&D team, Mecmesin developed the Combi Cork-i Extraction Tester, an innovative multi-function cork extraction testing system that tests both phases of de-corking synchronously.

Greek beauty product manufacturer guarantees production quality by updating to Mecmesin's digital torque testers

A manufacturer of a wide range of skin, hair-care, make-up and sun-care products based in Greece needed to replace their outdated torque testers with up-to-date digital torque testers to guarantee production quality and to ensure their products remained sealed. Mecmesin supplied the company with two Tornado 10N.m digital torque testers, which have the ability to test tamper-evident closures, an intrinsic part of their specification.
