Description

Disposable packaging for natural vnna

The technical field to which the utility model relates.

The utility model relates to the food industry and can be used as packaging for natural wine.

Currently, disposable packaging for various drinks, which are made in the form of metal cans, are widely used.

Such cans are very convenient in operation, light in weight, and easily open due to tearing of a weakened section on the lid or opening of a valve located in the lid. Usually this type of disposable packaging is used for transportation and storage of highly carbonated soft drinks, soft drinks, such as beer or gin and tonic, or Pepsi, etc., as well as strong drinks, such as vodka. Typically, metal cans are produced with a nominal capacity of 330 ml and 500 ml, so that you can consume the beverage in the package in a short time.

Known disposable packaging for a drink in the form of a metal can, containing a case made airtight, and a drink mixed in a case (Technical Specifications TU 1417-01-45700634-98 "Aluminum cans with easy-open lids for drinks.

State of the art

publ. 1998). The known design of such cans with lids (the upper element of the cans) is intended for bottling beer, juice, carbonated soft drinks and low alcohol drinks, as well as alcoholic beverages with a strength of up to 60%.

Structural limitations are that mildly oxidizable drinks, such as highly carbonated drinks or alcohol-based drinks, are usually placed in them, which limits the use of packaging.

The closest in technical essence and the achieved result to the present utility model is a disposable package for natural wine containing a case made airtight in the form of a metal can (RU 17515, B 65 D 1/12, 10.04,2001). Known packaging solves the problem of increasing functionality and increasing the assortment of drinks in packaging in the form of a metal can. For this, natural wine is used as a drink.

Usually it was previously assumed that in disposable packaging for a drink in the form of metal cans it is impossible to store natural wines, because they quickly reduce quality and taste. Natural wines are more susceptible to oxidation and fermentation than other drinks. However, studies have shown the possibility of placing natural wines in an airtight case with sufficient time for the sale of goods. For this purpose, various sorbents of gases and stabilizers of natural wines are used.

The main factor that distinguishes the storage and transportation of natural wines in metal cans is the practical absence of gas evolution from wines. Otherwise, the wine will ferment and cannot be sold. Carbonated drinks placed in

metal cans contain a large amount of dissolved gases, which form a vapor-gas cushion between the drink and the wall of the body. Intensively formed; vapor vaporization of alcohol contained in vodka drinks also form a similar pillow. In packages for natural wines, a gas-vapor pillow can only be artificially formed by boosting gas into the case when bottling wine. Moreover, as a gas for natural wines, it is impossible to use carbon dioxide or non-inert gases, as well as gases with good solubility in wine.

Utility Model Essence

The objective of this model is to develop and create disposable packaging for natural wine in the form of a metal can with improved characteristics.

As a result of solving this problem, it is possible to obtain a technical result, which consists in the fact that the safety and sealing of the housing increases when the ambient temperature changes.

This technical result is achieved by the fact that in a disposable package for natural wine containing a case made airtight in the form of a metal can, the ratio of the volume VK of the case to the nominal capacity VQ of the metal can indicated on the case is from (1 + 1.43 10) to 1.322.

A distinctive feature of this utility model is that the ratio of the volume VK of the case to the nominal capacity VQ of the metal can indicated on the case is from (1 + 1.43

10) to 1,362. The choice of the limits of the ratio of the volume VK of the case to the nominal capacity VQ of the metal can indicated on the case is determined by the following factors. On the one hand, when filling natural wine into a package, for example at room temperature, wine should not fill the entire internal volume of the case. Otherwise, when the temperature rises, for example, when transporting packages with natural wine, especially in the summer, thermal expansion of natural wine will occur and significant pressure will be applied to the inner surface of the case. Since liquids, in particular natural wines, are practically incompressible, the increased pressure will at least destroy the case cover with a weakened cross section or the side surface of the case. It was experimentally established that in order to maintain the integrity of the case filled with natural wines, the minimum ratio of the volume VK of the case to the nominal capacity VQ of the metal can indicated on the case should be (1 + 1.43 10).

On the other hand, if the maximum ratio of the volume VK of the case to the nominal capacity VQ of the metal can indicated on the case is more than 1,362, then the following situation may occur. When bottling natural wine in packaging at room temperature and subsequent transportation or storage at a lower temperature, the vapors of natural wine will condense in the volume of the case. As a result, a decrease in pressure will occur within the body volume. The can will be in the grip of atmospheric pressure and the housing will be substantially deformed. The maximum ratio is determined experimentally for real conditions of bottling and storage of wines.

It is advisable that the nominal capacity VQ of the metal can is 330 ml or 500 ml.

Information confirming the feasibility of implementing a utility model

The package has a housing 1 made airtight. Inside the case 1 is placed a natural wine 2. On one of the covers of the case 1 or on the side surface of the case there is a means 3 for opening the case. The tool 3 can be made in any known manner: as a part of a cover with a weakened cross-section, in the form of a valve, etc.

As drink 2 can be used a wide range of natural wines, white, red, dry, dessert, fortified, etc. Natural wine with a strength of up to 13% can be used, for example, wines such as Cabernet, Racetels, etc. Various fortified natural wine with a strength of up to 30%, various types of port, nutmeg, madeira, etc. can also be used.

On the can body there is information 4 about the nominal capacity of natural wine. The ratio of the volume VK of the case to the nominal capacity VQ of the metal can indicated on the case is from (1 + 1.43 10) to 1.322. As a result, a compensation volume 5 is formed inside the housing. The compensation volume 5 can be filled with an inert gas, for example nitrogen, which is under a slight excess pressure.

After placing the natural wine in the housing 1, it is sealed. Cornus 1 is combined into blocks and transported products. After purchasing the product, the consumer opens the housing 1 by means of means 3 - the wine is ready for consumption. Natural wine 2 can be consumed directly from the packaging, for example, with a nominal capacity of the case up to 330 ml, or can be bottled in additional containers (glasses, wine glasses, etc.), for example, with a nominal capacity of the case from 330 ml to 500 ml and more.
