Bottle caps: types, manufacture and application. Bottles with yoke caps

The cork, in the form in which it is known now, appeared in the 17th century, simultaneously with a glass bottle. Before that, it was also used, but in isolated cases. Most often, the closure of containers was carried out with the help of rags or pieces of wood, which led to spoilage of the contents and a deterioration in taste. Unlike wood, cork does not swell much, and with proper processing, the taste of the drink and the smell do not deteriorate.

General information

Bottle caps differ in shape and design. During the manufacturing process, special components are added that improve the protective function and act as an exclusive mark of the quality of drinks.

bottle caps

The cork for a wine bottle is tightly inserted into the neck of the container, retains its properties for a long time and is a product of natural origin, like a good quality drink. Corks are made long and difficult. The bark of the cork oak is initially stripped when the tree is about 30 years old. This material is not used in production as wine bottle corks are madeonly after 3 sessions. The second layer grows for about 10 more years. The production technology consists of several successive stages: six months of drying, careful selection, washing and treatment with a disinfectant solution.

Classification by material of manufacture

Bottle caps are different. It all depends on many factors, from which the purpose and material of manufacture are distinguished. The most common types of traffic jams:

  • cortical;
  • plastic;
  • metal;
  • rubber;
  • foil;
  • synthetic;
  • glass.

Corks for wine bottles cork (also found among some types of champagne). Plastic bottles with soft drinks are corked with plastic stoppers, and containers with mineral water and beer are closed with metal caps. Rubber products are used in the pharmaceutical industry. Many medicines are stoppered with foil stoppers.

Synthetic corks based on polyethylene are distinguished by the fact that they do not allow moisture to pass through and are easily pulled out with a corkscrew. The quality of these products may vary, silicone ones are considered the best in this category. The advantages of glass stoppers are ease of opening and closing, interesting appearance. Experts recommend using them for wine that is not designed for long storage.

Division by design features

Bottle caps are also available in micro-granular, screw and yoke.Microgranular has a homogeneous structure, high elasticity and resilience. The production technology is quite new: food glue and a waxy substance of organic origin (obtained from a cork tree) are added to cork granules with a size not exceeding half a millimeter. The whole process takes place under high pressure.

The screw plug has a low cost, eliminates the risk of cork disease, but is not strong enough. It is made of aluminum alloys and a synthetic gasket. Bottles with a yoke stopper can often be found in cosmetic stores and on the shelves with olive oil. Good tightness and the possibility of repeated use distinguish the bow plug from the rest.

Production Features

The cork compresses well, and thanks to this property, it can be pushed into the neck of the bottle, where it will tightly press against the walls of the vessel due to its elasticity. This is achieved by careful impregnation of the material and heating with steam (boiling). If the cork dries out, it will become hard. In production, it is pushed through the tube into the neck.

In order to protect the material from the effects of liquids in the bottle, it is treated with paraffin at high temperatures. The cork begins to harden when cooled, so it is kneaded in a special press in order to return the elastic structure.

Production of corks for wine

Bottle caps made from natural materials are an ideal way to sealaesthetics. The product is resistant to temperature, it is light, well passes the right amount of air, does not rot. Ordinary natural cork can last about 50 years.

Production starts from the moment the layer is cut from the tree. The bark is stored for one year in special rooms, after which it is processed at high temperatures. Then it is cut into plates and sent for sorting. Strips are made from the plates, followed by a groove of cylindrical plugs. The standard length is from 2.5 to 7 cm. It is believed that the longer the length, the higher the price of the drink.

The next step is to grind the cylinders to achieve a perfectly smooth surface. After that, the product is bleached and impregnated using wax. The final step is to burn out the company lettering on the cork or press under pressure. Sulfur dioxide is often added to the bottle under the cork to preserve the drink.

Rope plug

You can often find square bottles with a yoke stopper, which are produced by many manufacturers for the purpose of long and proper storage of various liquids. In most cases, the container is made of glass. They tend to be small in size, ideal for home storage of salad dressings and olive oil. Liter glass bottles with a cork of the type in question are used for bottling lemonades, liqueurs, tinctures, etc. For beautiful vintage-style containers,with a flared neck, a yoke stopper is a great way to keep milk, for example, fresh.

The yoke plugs consist of a cap made of high quality and safe plastic and a chromium plated stainless steel wire holder. These reusable products keep drinks fresh in the bottle for longer.

Dignity of the yoke plug

Bugel products are widely used for sealing vessels, while guaranteeing high tightness and reliability of packaging. Using these bottle caps, you can be sure of the convenience of use and the preservation of the properties of the drink. Repeated use allows you to achieve significant savings.

cork for wine bottle

Rope plugs are a worthy alternative to products of natural origin. For wine, this type is rarely used, since, according to experts, a wine bottle loses its aesthetic appearance that has developed over the centuries. However, environmental and economic aspects in the future may replace the classic ideas about bottle capping options.
