Description

The utility model relates to packaging means for storing, transporting and consuming food products and can be used for liquid, liquid-like and bulk food products, for example, juices, yoghurts, oatmeal, etc.

Known cans for storing and transporting fish, for example, preserves or herring fillets, containing a plastic case, in the neck area of which a small flange is made, a lid with a side that is mounted on the end of the flange. (http://aquaprodukt.net/preservy), (http://www.baltbereg.com/catalogue/index/18).

In this device, a groove is made inside the rim of the can lid, and the end face of the housing flange is installed in this groove. Typically, the case and the cover are made of the same polymer food material, which ensures high sealing of the device in a very wide temperature range (from -30 ° C to + 100 ° C), since the thermal expansion (compression) coefficients of the case and the cover are the same. This package is made by casting from polymeric materials. Banks are: round, square, rectangular, oval.

Plastic cans have several advantages:

- Low specific gravity.

- The ability to manufacture cans of a wide variety of colors and shades, as well as the ability to apply full color printing.

- Low vapor and gas permeability.

- Convenience of transportation.

- Preservation of external cleanliness. The container is not electrified from friction or contact with various objects, which eliminates the static attraction of dust and dirt.

- Reasonable cost (about 30% of the cost of a similar glass container and 45% - tin).

- It is possible to produce cans of individual sizes.

- Resistance to chemicals, ultraviolet rays and mechanical damage. Container does not react with the contents of the food product.

A limitation of these devices is the ability to transport only one type of food product inside the can.

The range of packages for yogurt is currently quite wide.

As the Romir company notes, the most popular packaging for yoghurts among Russian consumers remains European glasses of 125 g and plastic containers of 250 g each. For desserts, they increasingly use two-section containers, which make it possible to place components of different consistencies. (http://www.advertology.ru/print106423.htm).

According to Euromonitor International, hard plastic packaging is leading the market, which will remain the leading trend in the next five years.

If originally drinking yogurts were positioned as products for consumption on the go, now they are moving into the category of family products. Packaging larger packaging has become particularly popular. So, the dairy company Yeo Valley introduced a limited series of yogurt that complemented the existing product line in large 450-gram cups. The novelty was called "Damson & Plum" ("Prunes and Plums") and appeared in stores in the UK in July 2012, Upakovano.ru reports.

Wimm-Bill-Dann yogurt packing is carried out in plastic containers - “quadrants” - 4 cups of 125 g each. Consumers often prefer to break 1-3 cups off a whole flavor block. This feature of the consumption of yoghurts led to the fact that a huge amount of yogurt "scrap" appeared on store shelves, which was not identified not only by buyers but also sellers of stores. Accordingly, each subsequent buyer broke off the required number of cups from the whole "quad", and the seller had to throw away broken ones, in the literal sense, after the expiration date. In this regard, retail trade also created certain obstacles to the consumption of this product, forcing consumers to purchase yogurt only in whole packages. (http://company.unipack.ru/16689/).

A limitation of the use of the “quad” is also the impossibility of increasing the volume of the transported product in one cup, since the cup lid is made of foil in contact with the perimeter of the “quad”, which can lead to its separation, and when the cup volume increases, they spontaneously separate from each other. So, with an increase in the volume of the glass to 290 g, you have to use an autonomous container - a bottle equipped with a plastic screw cap, and for only one type or taste of yogurt. (http://www.utkonos.ru/item/1377985).

Various devices of two-section containers are known for transporting several food products, for example, juices, yoghurts of different compositions, and the like. (EP No. 0686575, US No. 3866820, US No. 4836380, WO 2006051383, GB No. 1053868, FR No. 2461657, US No. 6364519, US No. 6076673). The devices allow you to transport and store two types of food product, which is their advantage over plastic bottles.

However, the devices do not allow the use of sufficiently large volumes of container capacities in the manufacture of cups of hard plastic. In addition, the devices have a sufficiently high structural complexity, which accordingly leads to an increase in the cost of sales of the packaged product.

A rather simple device is two-section packaging for food products, containing two trays, each of which consists of a base, side and end walls with flat flanges outward in the upper part, and a flat cover, while one flange is common for two trays, the trays are made of thermoformed material, the lid is made of sheet or film polymeric material and is hermetically connected to the trays on the flanges, and the package is equipped with a handle connected to one of the trays at the top of the trays in place wall connections with flanges, each tray has a length of 215-255 mm and a width of 128-155 mm, and the depth of the tray is 30-100 mm. (RU, U1, No. 52832).

In this device, the connection of the trays with the lid is carried out by a thermal seam, 4-15 mm wide with a flange width of 5-15 mm. The device is designed to store and move food, medicine, etc. in field and field conditions and can be used in the armed forces, oil industry workers, gas industry workers.

A limitation of this device when used as the contents of food trays is that when the lid is opened, two trays open simultaneously, which leads to the need to simultaneously consume the products in them. In addition, with the simultaneous consumption of products and in the manufacture of containers in the form of trays for the user, there are certain inconveniences for the consumption of liquid or liquid-like food, for example, juices or dairy products. Therefore, for separate consumption of food products they are placed in separate soft packs, which complicates the device and leads to inconvenience of food consumption, because requires the use of any additional utensils.

A vessel made of deeply drawn plastic is known, which is a food two-chamber container containing two cups that are interconnected, a flange made outer on the side wall of each cup in the area of its neck, a lid made flat and mounted on the flange. (LE, No. 3718255).

In this device, two cups are inseparably connected by a common flange located on the outer surfaces of the cup side walls facing each other. There is foil on the flanges surrounding the cups and the common flange, and on the outside is a common thin cover. Cups are made of different volumes. A circular hole is made in the common thin lid above the neck of the smaller cup, which serves to pierce the foil layer with a tube. This device is similar to the packaging of Wimm-Bill-Dann's “Miracle” yoghurts, only the products were placed not in “squares”, but in two cups, closed with a common foil and a thin lid.

The advantage of this device is the provision of separate and non-simultaneous use of various liquid products in the cups.

The limitations of this device are:

- a small amount of used cups, as when used as a common lid foil and thin plastic, which do not have high rigidity, deteriorates the strength of the device as a whole, and it is possible to spontaneously separate the glasses from each other;

- insufficient strength of the device leads to increased requirements for transportation and storage (for example, the need for warehousing products with a limited number of rows in height);

- one-piece connection of glasses through a common flange, leads to a deterioration in the usability of products by the user;

- piercing a thin foil with a tube for a glass with a smaller volume makes it impossible to place and use a loose food product in it;

- the use of a common flange limits the range of shapes of glasses, which have to be made only in the form close to a rectangular parallelepiped.

The closest is a two-chamber container containing two glasses that are interconnected, a flange made outer on the side wall of each glass in the area of its neck, a lid made flat and hermetically mounted on the flange. (DE, No. 3715442).

This device is used to add processed grain, for example, oatmeal in a small cup to yogurt in a large cup by turning a small cup relatively large. Both cups are made of food-grade plastic, on the flange of which there is a common lid made of thin polymer or aluminum foil. Between the chamber flanges facing each other, there is a “weakened” plastic (of a smaller thickness than the thickness of the flanges), which acts as a hinge, while the length of the “weakened” plastic has essentially the same length as the width of the side wall of a small cup facing a big glass.

A limitation of this device is the indispensable simultaneous use of both products in glasses; narrowing the range of materials, because the use of flexible polymer for making cups is mandatory; insufficiently large volume of cups and the use of cups of only a very definite and rather complex shape. The use of a thin material, such as foil, as a common cover, when using a flexible polymer, worsens the rigidity and strength of the structure as a whole, which impairs the convenience of transportation.

The task solved by the utility model is the improvement of technical and operational characteristics.

The technical result that is obtained by performing the claimed utility model is an increase in the strength and volume of container capacities, improved usability, and the expansion of the range of forms.

To solve the problem with the achievement of the specified technical result in a known food container containing two glasses that are interconnected, a flange made outer on the side wall of each glass in the area of its neck, a cover made flat and hermetically mounted on the flange, according to the claimed useful each of the glasses is equipped with its own cover, the upper surface of the flange of the first glass is docked with the lower surface of the flange of the second glass, the shape of the end face of the flange of the first ana formed corresponding to the shape facing thereto sidewall surface of second cup with providing surface contact of the first cup flange end face to the facing thereto a side wall of the second cup, inserted tape, and connect the first and second cups together effected by the tape located outside lateral cup walls.

- a segment of the tube was made of elastic material;

- a segment of the tube was made of heat-shrinkable material;

- the glasses were made of polyvinyl chloride-polyethylene, or polyethylene terephthalate, or polystyrene, or polystyrene-polyethylene, or other hard polymer material with a thickness of 500-1000 microns;

- as a material for its own lid, thin food-grade plastic or food-grade aluminum foil with a thickness of 9 to 20 μm was used to access the necks of the first and second glasses by bending;

- the side wall of the second glass was cylindrical, and the end face of the flange of the first glass facing it was made with a concave cylindrical surface;

- the side wall of the second glass was made conical, and the end face of the flange of the first glass facing it was made with a concave conical surface;

- the first and second glasses were made equal in volume;

- the volume of the first glass was made smaller than the second glass;

- the height of the first and second glasses was made providing the location of their bottom in one plane;

- the side wall of the second glass was cylindrical, the end face of the flange of the first glass was made with a concave cylindrical surface, the side wall of the first glass turned to the second glass was made with a concave cylindrical surface, and the rest of the side wall of the first glass was made with a convex cylindrical surface;

- the side wall of the second glass was conical, the end face of the flange of the first glass turned to have a concave conical surface, the side wall of the first glass turned to the second glass was made with a concave conical surface, and the rest of the side wall of the first glass was made with a convex conical surface;

- the side wall of the second glass facing the first glass was convex, the end face of the flange of the first glass facing the second glass was concave, and the remaining parts of the outer surface of the side walls of the glasses were made cylindrical, either in the form of truncated cones, or truncated pyramids, or in the form faces of a direct prism.

The indicated advantages of the utility model, as well as its features are explained with the help of options for its implementation with reference to the accompanying drawings.

FIG. 1 is a drawing of the claimed device, in the assembly of glasses;

FIG. 2 is the same as FIG. 1, another option;

FIG. 3 is the same as FIG. 1, product image;

FIG. 4 is the same as FIG. 2, product image.

The food container (Fig. 1-4) contains two cups 1, 2, which are interconnected, a flange 3, 4 made outer on the side wall of each cup 1, 2 in the area of its neck, a lid made flat and hermetically mounted on the flange. Each of the glasses is equipped with its own lid 5, 6 (leaf tear-off valve). The upper surface of the flange 3 of the first glass 1 is docked with the lower surface of the flange 4 of the second glass 2. The shape of the end face of the flange 3 of the first glass 1 is made corresponding to the facing surface of the side wall of the second glass 2 with the surface contact of the end face of the flange 3 of the first glass 1 facing it the side wall of the second glass 2. A tape 7 is inserted into the device. The connection of the first and second glasses 1, 2 with each other is carried out by means of a tape 7 located outside their side walls.

The tape 7 can be made in the form of a segment of the tube (Fig. 1, 3), which is made of elastic material or heat-shrinkable material.

The tape 7 can be made in the form of two segments (Fig. 2, 4), located opposite with the overlapping gap of the region facing each other of the side walls of the first and second glasses 1, 2 and provided with an adhesive layer facing the side walls of the first and second glasses 1 , 2.

The first and second glasses 1, 2 are made of hard plastic, for example, polyvinyl chloride-polyethylene, or polyethylene terephthalate, or polystyrene, or polystyrene-polyethylene, or other hard polymeric material with a thickness of 500-1000 μm. This thickness provides high rigidity. The use of material with a thickness of more than 1000 microns is impractical, because this leads to unreasonable weight gain.

As the material of the own lid 5, 6, thin food-grade plastic or food-grade aluminum foil with a thickness of 9 to 20 μm was used to access the necks of the glasses 1, 2 by bending the own lid 5, 6. Typically, the material used for such covers is aluminum foil with a thickness 9 ÷ 11 μm, but, as tests have shown, the use of a conventional packaging polyethylene film with a thickness of 6 ÷ 10 μm, for example, as a tear-off valve is impractical, because unlike aluminum foil, it can be destroyed during transportation. Therefore, for a polyethylene film, the thickness range should be approximately doubled, i.e. 12 ÷ 20 microns. The thickness of food aluminum foil of 20 microns practically does not affect the functionality and bending ability of the tear-off sheet metal.

To further increase the rigidity of the assembly, the side wall of the second glass 2 is cylindrical, and the end face of the flange 3 of the first glass 1 is made with a concave cylindrical surface.

Or the side wall of the second glass 2 is made conical, and the end face of the flange 3 of the first glass facing it is made with a concave conical surface.

The first and second glasses 1, 2 can be made equal in volume.

The volume of the first glass 1 is made smaller than the second glass 2.

The height of the first and second glasses 1, 2 is made providing the location of their bottom in one plane, which ensures their stable position on a flat surface of the table.

The side wall of the second glass 2 can be made cylindrical, the end face of the flange 3 of the first glass 1 is made with a concave cylindrical surface, the side wall of the first glass 1 is made with a concave cylindrical surface facing the second glass 2, and the rest of the side wall of the first glass 1 is made with a convex cylindrical surface (Fig. 1, 2).

The side wall of the second cup 2 can be conical, the end face of the flange 3 of the first cup is made with a concave conical surface, the side wall of the first cup 1 is made with a concave conical surface facing the second cup 2, and the rest of the side wall of the first cup is convex conical surface (Fig. 3.4).

The side wall of the second glass 2, facing the first glass 1, can be made convex, the end of the flange 3 of the first glass 1 facing the second glass 2 is concave, and the remaining parts of the outer surface of the side walls of both glasses 1, 3 are cylindrical, or in the form of truncated cones, or truncated pyramids, or in the form of faces of a direct prism (in Fig. 1, 2 shows cylindrical surfaces, in Fig. 3, 4 - conical, other surfaces in the figures are not shown).

The manufacture of glasses 1, 2 and the operation of the device are explained below.

The first glass 1 and the second glass 2 are made by thermoplastic molding in the form of a punch-matrix, either using vacuum or using compressed air.

The shape of the end face of the flange 3 of the first glass 1 perform the corresponding form facing the side surface of the second glass 2 (Fig. 1-4).

After filling the products of the first and second glasses 1, 2, they are hermetically closed with their own covers 5, 6 (Fig. 1, 2), which are respectively installed on the flange 3 of the first glass 1 and flange 4 of the second glass 2. Own covers 5, 6 made of thin food-grade plastic or food-grade aluminum foil, is sealed on an adhesive adhesive layer applied on flanges 3, 4 or by heat sealing with heating on flanges 3, 4.

The first and second glasses 1, 2 are connected so that the upper surface of the flange 3 of the first glass 1 is joined to the lower surface of the flange 4 of the second glass 2, while providing a surface contact of the end face of the flange 3 of the first glass 1 to the side wall of the second glass 2 facing it. On the side walls of the first and second glasses 1, 2, a tape 7 is installed, which fastens the side walls of both glasses 1 and 2.

Since the upper surface of the flange 3 of the first glass 1 is joined to the lower surface of the flange 4 of the second glass 2, this prevents the glasses 1 and 2 from moving in the vertical direction, since the shape of the end face of the flange 3 of the first glass 1 is made corresponding to the side surface of the second glass 2 facing it, and the glasses 1, 2 are pulled together by a tape 7, this prevents their displacement in the transverse directions.

In the design, during storage, transportation and consumption of products, there is no common flange subject to kink or bending, therefore, the assembly strength is increased, and it is possible to use the first and second glasses 1, 2 with a large volume.

The tape 7 can be made in the form of a segment of the tube (Fig. 1, 3), which is made of an elastic material, for example, rubber.

However, it is most advisable to use heat-shrink material, which virtually eliminates the displacement of both glasses 1, 2 (Fig. 1, 3). Heat-shrinkable material has the ability to contract under the influence of heat and repeat the shape of the product on which it is worn. Tape 7 is put on the side walls of glasses 1, 2 in the form of a tube segment. The film sleeves are made of PET (polyethylene terephthalate) or PVC (polyvinyl chloride) sleeves. Advantages of a shrink sleeve (film) over others: gives high mechanical strength to the package; hides minor defects in the production of complex packaging; creates an impermeable layer for ultraviolet rays; easily removed from the surface of the container due to the presence of transverse or longitudinal perforation. The thickness of the tape 7 from PVC or PET is 40 ÷ 50 microns, the shrinkage of the tape 7 is made by steam.

The tape 7 can be made in the form of two segments (Fig. 2, 4), located opposite with the overlapping gap of the region facing each other of the side walls of the first and second glasses 1, 2 and provided with an adhesive layer facing the side walls of the first and second glasses 1 , 2. As two segments of tape 7, various self-adhesive tapes, for example, tape, can be used, which simplifies the assembly of the entire structure without significantly reducing its strength due to the fact that the upper surface of the flange 3 of the first glass 1 is joined the lower surface of the flange 4 of the second nozzle 2, and form an end flange 3 of the first nozzle 1 is formed corresponding to the shape facing the second side wall thereto cup 2, providing them with surface contact surface.

Thus, a rigid connection of the glasses 1, 2 themselves is realized, thereby improving the strength and increasing the volume of the container capacities due to the lack of a common flange connecting the glasses 1, 2, the usability is improved and the possibility of assortment of the glasses themselves both in shape and volume is increased.

The international standard ISO 9241-11 defines "usability" as the degree to which a product can be used by certain users in a certain context of use to achieve certain goals with due efficiency, productivity and satisfaction.

The term "usability" can be regarded as a synonym for the word "ergonomics" with the difference that the latter determines the minimum of specific physical efforts when using a thing, and the first - the final total degree of convenience, a measure of the intellectual effort necessary to obtain useful qualities of this thing and the speed to achieve a positive result when managing it.

The improvement of "usability" is directly manifested in the design and in the operating modes of the food two-chamber container.

The first and second glasses 1, 2 can be made identical in volume (not shown in Figs. 1-3). Approximately the same volume of glasses 1, 2 is rational to use when storing yoghurts of different composition or taste, for example, raspberry in the first glass 1, blueberry in the second glass 2. Products can be consumed first from the first glass 1 by bending or removing their own lid 5, freeing the neck of the first glass 1, then from the second glass 2 by bending and removing the cover 6. That is, both products can be consumed in a very short period of time. However, after removing the own lid 5 and consuming the product contained in the first glass 1, the first and second glasses 1 can be easily disconnected by removing or tearing the tape 7, and the product in the second glass 2 can be stored separately for a rather long time, and the first glass 1 may be thrown away.

The volume of one of the glasses, for example, the first glass 1, can be made smaller than the other, for example, the second glass 2 (Fig. 1-4). This embodiment is advisable to use, for example, when adding the contents of the first glass 1 to the second glass 2 due to the fact that the tape 7 is easily removed or torn. After removing the tape 7, the neck of the first glass 1 is placed above the neck of the second glass 3, and the contents of the first glass 1 are tipped into the second glass 2. The contents of the second glass 2 can be, for example, yogurt, and the contents of the first glass 1 can be a liquid-like product, for example, jam, jam, etc., or a loose product, for example, oat, corn flakes, corn sticks, popcorn, etc. After mixing, the product is consumed directly from the second glass 2.

The volume of the first glass 1 can be chosen much smaller than the second glass 2. For example, if the second glass 2 contains freeze-dried soup or some side dish, and the first glass contains spices. The product is consumed directly from the second glass 2 when adding the contents of the first glass 1.

For the above cases of food consumption, since the connection between the first glass 1 and the second glass 2 is made by tape 7, it does not require bending of the common flange connecting glasses 1, 2, or its destruction, usability is improved for glasses 1, 2 to be located anywhere after their separation.

The height of the first and second glasses 1, 2 can be made to ensure that their bottom is located in the same plane (Fig. 1) for their stable position on the flat surface of the table. This allows you to conveniently remove their own covers 4, 5, without removing the tape 7 from the first and second glasses 1, 2, and consume the products contained in them, for example, alternately.

In any case, through the use of tape 7, which is easily removable or destructible, the first glass 1 and the second glass 2 can be stored together or separately from each other, and when the contents of one of the glasses 1 or 2 are fully consumed, it can be thrown away.

Usability improves not only due to the possibility of using different volumes, but also due to the possibility of using various forms without compromising the strength of the assembly.

In various embodiments, the side wall of the second cup 2 can be made cylindrical, the end face of the flange 3 of the first cup 1 is made with a concave cylindrical surface, the side wall of the first cup 1 is made with a concave cylindrical surface facing the second cup 2, and the rest of the side wall the first glass 1 is made with a convex cylindrical surface (Fig. 1, 2). This allows you to reduce the transverse dimensions of the assembly.

In another embodiment, the side wall of the second cup 2 can be conical, the end face of the flange 3 of the first cup is made with a concave conical surface, the side wall of the first cup 1 is made with a concave conical surface facing the second cup 2, and the rest of the side wall of the first Cup made with a convex conical surface (Fig. 3, 4). It also allows to reduce the transverse dimensions of the assembly.

As can be seen from figures 1-4, the side wall of the second glass 2, facing the first glass 1, is convex, the end face of the flange 3 of the first glass 1 is made concave, facing the second glass 2, which prevents the first and second glasses 1, 2 from being displaced in the transverse directions , and there are no restrictions on the remaining parts of the outer surface of the side walls of the first and second glasses 1, 2, so they can be made cylindrical, either in the form of truncated cones, or truncated pyramids, or in the form of faces of a direct prism (in Fig. 1 , 2 bye anes cylindrical surfaces, Figure 2, 4 -. bevel, other surfaces are not shown in the figures).

As shown above, various possibilities (modes) of consuming the contents of the first glass 1 and the second glass 2 are provided, storage and placement in glasses 1 and 2 of completely different products is ensured, the possibility of using glasses 1, 2 in general of various shapes and volumes is achieved, which improves usability and technical and operational characteristics of the container. Manufacturers of packages and products can use containers of various sizes and shapes that meet the technical requirements and composition of the food products themselves.

The most successfully declared "Food-grade two-chamber container made of hard plastic" is industrially applicable in the food industry for storage, transportation and consumption of food products.
