Description

The claimed invention relates to the design of a disposable container for food products, which can be used both as a cup for drinking hot and cold drinks, and for packaging and storage of food products.

Known from the prior art is a corrugated paper cup described in PCT patent W022008 / 064537 with priority from 01.12.2006, which includes a cup body (1), a cup bottom (2) and a cup sleeve (3). The cup sleeve has horizontal and vertical corrugated strips (4), on which there are many grooves (5).

The disadvantage of this product is that the paper tends to expand, decrease in volume depending on the humidity of the air, which is constantly changing. At high humidity and even a slight temperature difference in the paper cup, due to moisture absorption, the size and shape of the collar of the glass neck changes, which does not allow using the lid on the glass, and also does not allow long-term storage of products such as drinks, sauces, sour cream, etc.

The closest in technical essence is a glass for hot and cold drinks known from patent No. 114828 with a priority of 08/19/2011, including a body that consists of a conical wall, a bottom and a neck with an annular collar, characterized in that the annular collar consists of the convex ring and the cylindrical part located under the convex ring with the ratio of the heights of the entire annular collar H to its cylindrical part h equal to 2.8 ± 0.1, the annular collar is located relative to the side conical wall at a distance of L = 2 ± 0.3 mm, the bottom has a concave shape inside the glass, the side conical wall is made with stiffening ribs, while the glass is made of thermoplastic polymer material, for example, polystyrene, polypropylene, by thermoforming.

However, this device is intended for use in vending machines and is not intended for storing food.

The technical result of the claimed invention is to increase the strength and stability of containers for food products.

The claimed technical result is achieved by the fact that the container for food products having a fillable internal volume formed by a body and a base, and the container is made of an extruded polymer film, and the filled inner volume formed by a body in the form of a truncated cone with smooth transitions into a square base, while the upper part of the body having the shape of a circle is made with an edge bent around the perimeter. Stiffeners are located from the square base up to mating with the surface of the truncated cone. The container for foodstuffs is made of polyethylene terephthalate film with a density of 1.4 g / cm3. The container is made of extruded polymer film to increase its strength. Since the area of the square exceeds the area of the circle, the square base gives the container more stability when using it, and the filled internal volume formed by the body is made in the form of a truncated cone, and stiffening ribs that rise from the base up to mating with the surface of the truncated cone provide a stable shape of the container when filling it liquid such as a drink. The filled internal volume of the container can be 400 ml, 300 ml, 200 ml, or a smaller volume, therefore, the width of the square base, the radii of the base, the height of the stiffening ribs, the height of the container and the diameter of the neck of the container may be different. The upper part of the body is in the form of a circle with an edge bent around the perimeter that acts as a lock, allows you to use a container with a hermetically sealed lid and can be used both as a glass for drinking hot and cold drinks, and for packaging and storing sauces, various cocktails, smoothies, yoghurts, sour cream, ice cream and other food products. The container is made of extruded polymer film. It is preferable to use polyethylene terephthalate (PET) film, which has a high density of -1.4 g / cm3 and, accordingly, greater strength and stiffness in comparison with products made of polystyrene (PS), oriented polystyrene (OPS) and polypropylene (PP) films of the same thickness. For comparison, the density of PS, OPS is -1.05 g / cm3, and the density of PP is 0.92 g / cm3.

The essence of the technical solution is illustrated by drawings, where figure 1 shows a container for food products housing 1, base 2, edge 3. Figure 2 shows a container for food products housing 1, base 2, edge 3, stiffener 4. Figure 3 shows a container food grade base 2, edge 3.

A container for food products with a filling internal volume formed by a body 1 in the form of a truncated cone and a base 2. A container made of an extruded polymer film has a square base 2 from which upwards to mate with the surface of a truncated cone on the surface of the body 2 there are stiffening ribs 4, while the upper a part of the body 2 having the shape of a circle is made with an edge 3 bent around the perimeter.

The food container is used as follows. The internal volume formed by the body 1, the stiffening ribs 4 and the base 2 is filled, for example, with a cocktail, then, using the edge 3, which acts as a lock, is tightly closed with a lid. The lid can contain an opening for a cocktail tube or it can be completely sealed.

The container is made on special thermoforming machines (TFM) by thermoforming. The PET film from the roll unwinding unit is pulled along the guide device to the heating zone, where the film is heated and softened due to the radiation of the heaters. Then the heated film is transferred to the forming zone, where the upper and lower parts of the mold are closed and the film is drawn into the lower part of the mold by punches. The container is molded into shaping molds by supplying air from above under pressure and vacuum suction of air from the lower part of the mold, then holding the blank in a cooled mold for crystallization, after which the products are moved to the cutting press, where cutting takes place formed products from the film and storage of finished containers in a stack.

The set of features is new and allows you to achieve the claimed technical result.

Claims (1)

A container for food products, which has a filling internal volume formed by a body made in the form of a truncated cone, smoothly turning by mates into a square base, while the upper part of the body, which has the shape of a circle, is made with an edge bent around the perimeter that acts as a lock, which differs in that, that the body of the container, made of an extruded polyethylene terephthalate film with a density of 1.4 g / cm, is formed by the method of thermoforming, and the container has a square base, from which stiffeners are located upward to mate with the surface of the truncated cone.
