Brothers Drinks manufactures and co-packs a wide range of alcoholic and non-alcoholic beverages with both Roll on Pilfer Proof (ROPP) and crown bottle caps. This family company produces a variety of innovative flavours, and maintaining the freshness of the drinks is essential to their enviable reputation for quality.
To improve the quality and storage of their premium $1000 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.
Cork extraction strength is mostly used in the development of uncorking solutions for Champagne and sparkling wines. It is critical to measure the extraction force of corks in order to maintain a balance between easy opening of bottles by consumers, whilst avoiding exploding corks.
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.
For over a century Água de Luso has been one of Portugal's most famous names in mineral water. Água de Luso's mineral water is packaged in a variety of sizes of plastic (PET) bottles and it is essential that the caps on their bottles are easy to open, while at the same time applied tightly enough to ensure the bottles do not leak.
Sibel manufacture corks for the wine and spirits industry in the Champagne region of France. They pride themselves on working closely with their clients, taking into account their requirements and expectations for safety. A factor concerning Champagne and sparkling wine, in particular, is the risk of injury from a 'popped' cork when opening a bottle. Even when handled properly, pressure within the neck of the bottle means a cork could be released at approximately 100km/h.
The packaging of wine has great influence on the quality of the product delivered to the customer. Traditionally the method of closure has been the natural, or latterly synthetic, cork stopper. This solution, despite attaining high standards of sealing and taste preservation, can present problems for the end user attempting to remove the cork. As a result, the industry has developed alternative screw-cap designs aimed at achieving more consistent and reliable performance.
The rotational force needed to remove the closure spout from a sports cap body is measured using the Steinfurth Rotation Tester for Sport Closures mounted on a Mecmesin tensile tester. This ISBT test simulates a person biting or pulling on the spout when attached to a PET preform and requires specific tensile test equipment to meet the standard.
The pull force needed to separate the tear-off membrane base from the spout of the sports closure is measured using a custom fixture. This ISBT test measures the tensile strength of the assembled product.
Barry M Cosmetics Ltd. are the leading British colour cosmetics brand, offering a comprehensive range of products for face, eyes, lips and nails. Their heritage began in 1982, by recognising the gap in the market for fashionable, on trend, vibrant colour choices in the cosmetics industry. The company’s reputation centres not only on drama and high quality, but also a strict policy to be cruelty-free in the testing of finished products and ingredients, in-house or within their supply chain.
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.
A repeatable test system to check the opening force of flip cap lids, accommodating 3 different diameter caps with minimal fixture changeover. Prevention of accidental loadcell damage was also a pre-requisite as this had been a problem previously at Betts Ltd. (now part of Albea).
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.
The customer also required a torque tester to determine the torque necessary to operate the lipstick barrel.
The Royal Botanic Gardens, Kew have undertaken an international conservation initiative to preserve seed specimens of over 24,000 plant species, protecting them from extinction at the Millennium Seed Bank at Wakehurst Place, West Sussex. Scientists at the Millennium Seed Bank required a simple, yet consistently accurate method of achieving a hermetic seal on the seed bottle caps.
Pfeiffer, based in Germany, (and now part of AptarGroup) are a leading manufacturer of atomisers and dosing systems for the pharmaceutical and cosmetics industries. The company required a torque test unit to measure the application and release torque of their pump products.
A system was required to measure the push-on force and removal force of an injection-moulded cap from a new design of oil can. The innovative design of the cap was opened by applying a downward pressure to the back, so flipping up the front portion allowing the oil to be poured. Both the push-on and pull-off tests needed to be completed without removing the oil can from the fixture.
