Description

The utility model relates to the production of plastic containers for the food industry and can be widely used for packaging food drinks.

The design of a plastic bottle is widely known, including a body, a neck and a bottom. This plastic bottle is universally used in the food industry for bottling, storage and transportation of beer and soft drinks in them.

As you know, most food industry enterprises do not have their own packaging production sites and order its production to specialized enterprises that have production facilities for the manufacture (molding) of containers, in particular bottles. An empty bottle after manufacture during the period of its use (transportation to the customer’s enterprise, storage in warehouses) is exposed to contaminants or bacteria present in large quantities both in the production environment of the plastic packaging manufacturer’s enterprise and in the environment during its transportation and storage.

At the same time, the food industry places high demands on the hygienic cleanliness of containers used in its production. In order to ensure guaranteed minimum contamination and microbiological contamination of packaging containers, which prevent the quality reduction and increase the shelf life of the product packaged in containers, various methods are used to maintain the sterility of the internal volume of an empty bottle before filling it with food. Such methods include methods of chemical washing and sterilization of containers, in particular bottles, immediately before the technological transition of filling containers with food products, which are characterized by the great use of manual labor, minimal mechanization and automation. In addition, bottles subjected to such sterilization must be additionally very thoroughly rinsed. In addition, the use of chemicals for such sterilization enhances the negative environmental impact. Other methods of sterilizing containers are known, for example, when the technological transition of transferring empty bottles after molding into the bottling shop is combined with the operation of sterilizing bottles, for example, ozone. This technological transition is carried out in an airtight workspace, and empty sterile bottles are transported through a transport pipe using purified, sterile compressed air (see Bolog M.K., Litishky G.A. "Electric Antiseptics in the Food Industry", M, 1988. )

For the closest analogue of the claimed utility model, the well-known design of the plastic bottle is the cylindrical body, neck and bottom (see patent RU No. 62581, Ml. B65D 1/02, publ. 04/27/2007).

From the prior art it follows that today the hygienic purity of the internal volume of an empty bottle before bottling is supported only by various ways of sterilizing it immediately before filling the bottle with a food product.

As you can see, maintaining the internal volume of an empty bottle that meets high hygienic standards in the food industry is quite complex, environmentally unsafe and economically expensive.

The prior art, the applicant has not identified a single source of information containing information about the designs of empty bottles, allowing to maintain (maintain) the hygienic purity of the internal volume of the empty bottle for a long time after its manufacture (for example, when transporting empty containers from one enterprise to another, when storing the finished product empty food packaging in warehouses), until the stage of filling the bottle with food product, which allows to reduce the cost of the finished food product in enterprises that do not have their own production of packaging containers (purchasing finished packaging at specialized enterprises - manufacturers of empty bottles) due to the exclusion from the process of complex, expensive and sometimes environmentally unsafe transitions associated with washing (sterilization) of empty bottles before filling them with food.

Thus, the technical result, which this utility model is aimed at, is to create a bottle design that allows preserving the hygienic purity of its internal empty volume for a long time between its manufacture and filling with a food product, which allows reducing the cost of finished products at food industry enterprises due to exclusion of technological transitions for sterilization of the internal volume of an empty bottle immediately before it is filled with food ohm

The specified technical result is achieved by the fact that the well-known plastic bottle, including the body, neck and bottom, according to the utility model, is additionally equipped with a sealing membrane located on the open end of an empty bottle, installed after molding the bottle with the possibility of its removal immediately before filling with the food product.

The presence on the open end of an empty bottle of a membrane installed immediately after molding the bottle with the possibility of its subsequent removal immediately before filling the bottle with food product ensures the hygienic purity of its internal volume for a long time between the manufacture of the bottle and filling it with food product. This is due to the fact that during molding, the inner volume of the empty bottle is sterilized by the temperature at which molding is performed, and the membrane installed after molding seals the sterile inner volume of the empty bottle from contact with the environment and completely eliminates any contact of the internal volume of the empty bottle with contaminants or bacteria present in the environment during the period between applying the membrane to the open end of an empty bottle and removing the membranes Before filling the bottle with a food drink.

The utility model is confirmed by drawings.

Figure 1 shows a schematic diagram of the inventive bottle; figure 2 (a) is a view of I (enlarged) (a variant of the location of the membrane covering the end of the neck); figure 2 (b) is a view of I (enlarged) (a variant of the location of the membrane at the end of the neck); figure 3 (a) is a view along arrow A (enlarged) version of the location of the membrane on the open end; figure 3 (b) is a view along arrow A (enlarged) option for the location of the membrane covering the end of the bottle.

The bottle contains a housing 1, a bottom 2 and a neck 3. The open end 4 of the neck 3 is equipped with a membrane 5.

The methods for arranging the membrane 5 on the open end of an empty bottle can be different: the membrane 5 can either cover the outer surface of the neck 3 (Fig. 2 (a) and Fig. 3 (b), or can be located directly on the end 4 of the empty bottle (Fig. 2 ( b) and Fig. 3 (a). The methods for holding the membrane 5 on the open end 4 of an empty bottle can be different, for example, using glue approved for use in the food industry, as well as using other types of adhesion of a chemical or physical nature, approved for use in food industry and allowing to remove this membrane 5 without problems before filling an empty bottle with a food drink.

The membrane 5 is equipped with an element that allows you to remove before filling an empty bottle of food product. This can be either a tongue 6 on the membrane 5 located around the end face 4 of the empty bottle, or a specially formed fold 7 on the edge 8 of the membrane 5, covering the outer surface of the neck 3 of the bottle, or any other configuration that allows you to easily remove this membrane before filling the empty bottle .

The membrane 5 can be made of any film that is approved for use in the food industry and approved for contact with food products.

Before the location of the membrane 5 on the open end 4, it is cut out (cut out) along an annular or curly line. The dimensions of the membrane 5 either coincide with the outer size of the open end 4 of the neck 3 for its application only to the surface of the open end 4 of the empty bottle, or be larger for the option of covering it with the outer surface of the end of the neck 3.

Upon receipt of the claimed empty bottle for filling it with food, in particular for bottling, this membrane 5 is removed from the open end 4 of the neck 3 of the empty bottle. The removal of the membrane 5 can be carried out either manually or using various mechanical devices that capture the membrane 5 by the element (tongue 6, fold 7), or using discharged air.
