Description

The utility model relates to packaging made by combining several components made of polymeric material, for example, polyethylene film, and can be used, for example, for packaging food products, in particular, easily damaged confectionery products, or other food and non-food products and products. ...

Known packaging for food products, which is a bag of film polymer material for hermetic sealing with evacuation and with the possibility of filling with an inert gas, while the bag is divided into isolated sections from one another, designed to accommodate the same type or different products or parts of one product, by means of at least one weld seam made with the possibility of separating sections along it from the package without breaking their tightness with the formation of separate packages (see the certificate of the Russian Federation for useful model No. 5579, IPC V65 V 25/20, publ. 16.12.1997. )

It is also known packaging of single-brewed products, which is a bag of film polymer material or metal foil for hermetically sealed with evacuation and with the possibility of filling with an inert gas, divided into sections isolated from one another by means of welded seams, at least one weld seam has one a longitudinal line of weakened strength, formed, for example, by perforation, designed to accommodate in them the same type or different products or parts of one product, made with the possibility of separating the sections along it from the package without breaking their tightness with the formation of separate packages - sachets, while the walls of the sections are additionally fastened to each other by at least one internal partition dividing the inner cavity of the sections into separate chambers, while notches are made above each chamber in the weld and on the adjacent sides of each section (see RF patent for utility model No. 110719, IPC В65 В 25 / 00, publ ... November 27, 2011).

However, the known packages cannot be used as the simultaneous packaging of dissimilar items: either two different food products, or the simultaneous packaging of a food and non-food product. This is due to the impossibility of ensuring the isolation of these objects relative to each other. In addition, due to evacuation, the known packaging is difficult to use for packaging easily damaged items, since during its transportation and / or movement, unauthorized contact with foreign objects is possible, which can lead to a violation of the integrity of the packed item even without violating the integrity of the package. At the same time, in the known packaging, it is difficult to control the first opening, which, along with the above circumstances, significantly reduces the consumer properties of the packaging.

Known box for packaging candied fruit, containing a lower plate and an upper pressure cover, which are connected by tight pressing and form a closed spherical space - an inner capsule - to accommodate the packaged product (see utility model patent of the People's Republic of China, IPC B65D 81/36 , B65D 85/60, publ. 12/15/2017). At the same time, it is assumed that after using the famous box as a food packaging due to its shape resembling a flying saucer, it will be used as a children's toy, developing an interest in new knowledge.

However, the known construction has the following disadvantages. The constituent elements of the packaging are made of hard plastic (for a more reliable connection). At the same time, this leads to a sharp increase in the weight of the package, and, accordingly, to its rise in price. By virtue of its rigidity, the known packaging ensures safety during storage and transportation of easily damaged products inside it. However, in fact, inside the package there is a gaseous environment from the environment during its initial assembly, which can adversely affect the storage of a number of food products containing precisely sugar, for example, due to the increased moisture content. In addition, the known packaging does not allow simultaneous packaging of either several food products in the absence of their additional primary packaging (wrappers, labels, etc.), or food and non-food products due to the impossibility of ensuring their isolation relative to each other, as well as to carry out a reliable control procedure. the first opening of the package, which also significantly reduces the consumer properties of the package.

Known packaging jar in the form of a plastic egg, made of food plastic, divided into two parts, with one part separated from the other by a separating pad made of food cardboard or foil liner for induction sealing and allowing the use of food and non-food products in one container ( see RF patent for useful model No. 94955, IPC B65D 6/00, publ. 10.06.2010).

The known design has the following disadvantages. Despite the potential to accommodate two dissimilar products in a known package, only one hermetically sealed compartment is provided. Thus, it is impossible to place two different food products isolated from each other in it. Due to the design of the package, in which the connection of the forming parts of the package occurs due to putting them on top of each other, it does not allow to exclude unauthorized separation of one part from another, for example, at the moment of application of force at the point of connection of the parts upon impact or in case of involuntary pressing. The well-known can is made from plastic, which significantly rises in price with an increase in the volume of packaging due to the greater mass of the material used for the production of packaging. In addition, due to the specificity of induction sealing, with an increase in the size of the package, the diameter of the part to be sealed increases, which will also lead to a sharp rise in the cost of manufacturing the package. This leads to the fact that the small size of the known package is economically feasible, imposing restrictions on the volume of the packed products, which, in addition to the already mentioned restrictions on the relative placement of two food products, leads to a decrease in the consumer properties of the known package.

Closest to the claimed technical solution is the packaging of cotton candy, containing hemispherical shells of thermoplastic film, welded together. In this case, the package, in addition to the welded seam, has a seam of the walls of the air inlet channel, a sealing seam and an air inlet channel in the form of a nipple (see RF patent for invention No. 2165149, IPC A23G 3/00, B65 B 9/02, B65 B 31 / 04, publ. 20.04.2001).

The known design, in which an easily damaged food product can be in a special gaseous medium in a sealed compartment, limited by hemispherical shell elements welded along the seam along the contour, allows you to visually monitor an unauthorized first opening, in which the product, upon contact with the external environment, quickly becomes unusable, providing at the same time, storage and transportation of goods and being relatively inexpensive due to the material used. However, the known packaging does not provide for the placement of several different products without primary packaging, both, for example, simultaneously food and food with non-food, due to the impossibility of ensuring their isolation from each other, which also reduces its consumer properties.

The objective of this technical solution is to create inexpensive packaging with improved consumer properties, which allows simultaneous packaging of several dissimilar products and goods, both food and non-food, in the absence of their primary packaging.

The technical result achieved when solving the problem is the creation of packaging that provides the division of the internal space of the packaging into separate zones with a constant configuration, which do not change or quickly restore their shape and volume during the use of packaging with packaged products and goods during storage, transportation and other manipulations.

The task is achieved by the fact that a package containing, as a forming part, a shell made of a polymeric material with a rounded element in the central part, with a gaseous medium inside the package, according to the utility model, contains a membrane connected to the shell and a forming counterpart that limits the inner space of the package, by means of a common weld formed due to thermal action.

It is advisable to place the weld along the edge of the rounded element in the central part of the shell.

It is preferable to make a package containing, as shaping parts, two shells mating to each other with rounded elements in the central part, close to a hemisphere.

It is advisable to make the forming parts of the package and the membrane from the same materials. It is advisable to choose the thickness of the polymer material up to 700 microns.

Both continuous and perforated membranes are allowed.

The membrane can be made of both transparent and opaque material.

It is allowed to make a package with several membranes connected to the forming parts of the package by means of a common welded seam.

The weld seam can be made both rounded, for example, repeating the contour of the edge of a rounded element of the forming shell, or in the form of a set of segments located at an angle to each other, forming a broken line, or a polygon.

The presence of a membrane, i.e. partitions made of a flexible thin polymer material, for example, polyethylene film, allows you to zone the inner space of the package. At the same time, a common weld seam connecting the membrane and the forming elements of the package serves for the same purpose - a shell made of a polymer material with a rounded element in the central part and a forming element corresponding to it, for example, a similar shell with a rounded element or a shell without such a rounded element.

The presence of just a common seam indicates the simplification of the production of such a package, when a seam formed as a result of thermal action, for example, welding, and connecting three or more elements of the package, is formed in one technological operation. The creation of several seams, for example, one between the membrane and one shell, and the other between the membrane and the mating element, will complicate the production, because It will also require the movement of packaging blanks, possibly with a product (food product) already placed inside it, and sequential sequential placement of the components of the packaging in the welding unit, which significantly increases the number of technological operations, and, accordingly, the production cycle time for creating one packaging unit as a whole and its cost.

In addition, due to thermal action, stresses arise in the material and it actually collapses in the region of the seam. Thus, a single common seam minimizes the number of areas (zones) of material destruction, increasing the strength of the package as a whole, which improves its consumer properties.

Inside the package, in all newly formed zones, there is a gaseous medium under pressure, which is pumped into it during the manufacturing process. This gaseous medium completely fills the inner space of the package, bounded by the forming elements and the common weld seam.

When an external influence is exerted on the packaging area where the gaseous medium is located, for example, during transportation, placing on the shelf of commercial equipment, contact with the buyer's hands, unauthorized falling from a height from the buyer's hands, due to internal pressure and physical properties of the gaseous medium, the material of the forming elements restores the original shape of the package. Thus, the configuration, namely the volume and shape, of the inner zones of the package either does not change (with a strongly excessive internal pressure of the gaseous medium inside the package), or quickly recovers to its primary form, which levels out and eliminates the external effect on the packed, for example, easily damaged or shapeless. products in the package of the proposed design, keeping these products intact, which also increases the consumer properties of the package.

At the same time, the presence of a membrane and the creation of additional zones completely or partially isolated from each other in the inner space of the package, allows placing in each zone under one or several items of both food and non-food purposes at the same time, for example, a food product in one zone and another food product or non-food gift toy in another zone, which significantly improves the consumer properties of the packaging, expanding the scope of its application. Making the partition in the form of a membrane, i.e. flexible and thin, allows you to minimize the internal volume that such a partition occupies, leaving as much space as possible for the direct placement of packaged food and food and non-food items, which also improves the consumer properties of the package.

Placing the weld along the edge of the rounded element in the center of the shell allows for easier shaping and restriction of interior space. The execution of a package containing, as shaping parts, two shells that match each other with rounded elements in the central part, close to a hemisphere, allow you to obtain a package with an attractive appearance and an internal space convenient for placing food or other items with simplified maintenance of the shape of the package in the force of a rounded forms in general.

Making the forming parts of the packaging and the membrane from the same materials makes it possible to further simplify the production of packaging, to more accurately calculate the time and temperature of exposure to the material when creating a weld, which increases the strength of the seam and reduces the cost of packaging production.

The choice of the thickness of the polymeric material of the packaging elements up to 700 microns is also due to the simplification of the calculation of the parameters of the temperature effect - the exposure time and the temperature value of the heating element, which will make it possible to create a more durable and reliable common seam connecting all structural elements of the package.

The execution of a solid or perforated membrane is due to the peculiarities of the technological equipment and the specific features and characteristics of the goods being packaged.

When packaging of the same type of goods is required, for example, of the same type of food, but of different colors to improve consumer qualities, it is allowed to use a perforated membrane, which retains the division into zones of the inner space of the package, but creates virtually a single internal pressure in the entire space by means of a single blower of a gaseous medium in the package. simplifying and cheapening its production. In the case when it is necessary to create a package with zones completely isolated from each other for packing dissimilar goods and excluding contacts between them, for example, a food product without primary packaging and a non-food item, several blowers of a gaseous medium can be used in the equipment for the production of such a package, by which are filled in separate zones, and it is possible to create a different internal pressure in each of the zones of the package.

The choice of the material of the structural elements of the packaging, transparent or opaque, is also dictated by the properties of the product being packaged, allowing interaction with external light sources, for example, sunlight, or requiring minimization of such an effect.

The presence of several membranes in one packaging unit, connected to the forming parts of the packaging through a common seam, allows an increase in the number of zones of the inner space of the packaging, which increases the number of units of goods placed in the package at the same time and also improves the consumer properties of the packaging.

The contour of the common seam can be made both rounded, for example, repeating the contour of the edge of a rounded element of the forming shell, or in the form of a set of segments located at an angle to each other, forming a broken line or polygon. The choice of the configuration of the contour of the common welded seam is due to the choice of the configuration of the volume formed by the packaging elements, for example, close to the shape of a ball or polyhedron, which, in turn, is determined by the choice of the shape of the items / food to be packaged, expanding their range and, thereby, improving the consumer properties of the packaging generally.

The utility model is illustrated by the following drawings, where figure 1 shows an example of the packaging, side view; figure 2 is the same, top view; Figures 3 and 4 show examples of packaging with a common weld seam of various configurations, top view; Figs. 5 and 6 show an example of a solid membrane (Fig. 5) or perforated (Fig. 6); Figures 7 and 8 show an exemplary embodiment of a package containing, as shaping parts, two shells mating to each other with rounded elements in the central part, close to a hemisphere; Fig. 9 - node I in Fig. 7 on an enlarged scale.

Positions in the drawings denote the following: 1 - a shell with a rounded element in the central part; 2 - membrane; 3 - shaping element, a response to the shell 1; 4 - common weld seam.

A package containing, as a forming part, a shell 1 made of a polymeric material with a rounded element in the central part, is filled with a gaseous medium inside the package (Figs. 1, 7 and 8).

The package contains a membrane 2 connected to the shell 1 and the forming counterpart 3, which defines the inner space of the package (Figs. 1, 7 and 8).

The shell 1, the membrane 2 and the shaping counterpart 3 are connected by means of a common welded seam 4, formed as a result of thermal action (Figs. 2-4 and 9).

The membrane 2 is expediently made of a thin polymeric film material. Membrane 2 can be made either continuous (Fig. 5) or perforated (Fig. 6) from a transparent or opaque material. Depending on the type, size, configuration and other characteristics of the food product to be packaged and other goods, it is possible to make the membrane 2 also with a rounded element in the central part (Fig. 8).

It is allowed to carry out a package with several membranes 2, connected to the forming parts of the package - shell 1 and its counterpart forming element 3 - by means of a common welded seam 4.

Preferably, the membrane 2 is made with an outer contour repeating the outer contour of the shell 1 or of the forming element 3 mating with the shell 1. .2-6).

The placement of the weld 4 is advisable along the edge of the rounded element in the central part of the shell 1 (Figs. 2-4, 9). The welded seam 4 can be made both round (Fig. 2), for example, repeating the contour of the edge of the rounded element of the forming shell 1, or in the form of a set of segments located at an angle to each other (Fig. 3), forming a broken line, or a polygon (Fig. 4).

It is preferable to make a package containing, as shaping parts of the shell 1 and the corresponding shaping element 3, two shells that are mutually opposite to each other with rounded elements in the central part close to a hemisphere (Figs. 7 and 8).

It is expedient that the forming parts of the package - the shell 1, the corresponding forming element 3 and the membrane 2 - are made of the same materials. It is advisable to choose the thickness of the polymer material up to 700 microns. With this design, the overall weld seam 4 will be more uniform in width and thickness. At the same time, depending on the choice of the products to be packaged, it is possible to design the forming elements from various materials. For example, the shell 1 and the corresponding forming element 3 are made of polyethylene film, and the membranes are made of polypropylene film. In this case, these and any other film polymeric materials can be used in the manufacture of the shell 1, the corresponding forming element 3 and the membrane 2 in any other combination with each other.

The utility model is used as follows.

When packing the product into one form-forming part of the package - the casing 1, namely, in its rounded element in the central part, the packaged product is placed, for example, easily damaged food products, in particular, candy (Figs. 1 and 7), cotton candy (Fig. 8) ... The installation of the shell 1 can be carried out in a pre-prepared cradle for its central part either on a metal frame or in a hole in the packing table.

The membrane 2 is laid on the shell 1, which is made solid (Fig. 5) or perforated (Fig. 6) from a transparent or opaque material. If the membrane 2 is also made with a rounded element in its central part (Fig. 8), it is advisable to rotate the membrane 2 upward with the rounded element when performing this operation.

It is allowed to perform a package with several membranes 2, which are subsequently connected to the forming parts of the package - shell 1 and its counterpart forming element 3 - by means of a common seam 4. In this case, they are installed one on top of the other.

A second item to be packaged is placed on the membrane 2, for example, any non-food product (Figs. 1 and 8), or a gift children's toy (Fig. 7).

The top is covered with a counterforming element 3, which limits the inner space of the package as a whole.

The counterforming element 3 can be made in the form of a thin film without a molded cavity in its central part (it is advisable to use it when packing thin products) and in this case the reverse part of the package will be a flat surface, or with a molded cavity in its central part, for example, square (figure 1) or round (figure 7 and 8) shape. If the cavity in the mating element 3 is rounded, it is advisable to make the rounded elements on the shell 1 and on the mating element 3 similar in size to each other and approximate to the hemisphere (Figs. 7 and 8).

The presence of cavities for placing products / food products and the choice of their shape in the shell 1 and the counterforming element 3 is determined by their type (food / non-food), size and configuration of the packed products.

The forming elements of the package with the products to be packaged are transferred to the heat-affected zone, where, for example, through the contact of the shell 1 with a highly heated wire element, a closed along the contour common weld seam 4 (Fig. 9) is formed, joining and welding in the region of the weld seam the material of all the forming elements - shell 1, membrane 2 and the shaping element 3, which is counter to shell 1, forming a closed space between the seam 4 and the shaping surfaces of the shell 1 and its counterpart 3. The configuration of the contour and the location of the weld 4 is determined by the characteristics of the shaping elements - the presence of molded cavities for placing goods, the form of their execution, for example, rounded or rectangular, as well as their location on the forming elements of the package as a whole and the products to be packaged. It is advisable to place the weld 4 along the edge of the rounded element in the central part of the shell 1 (Figs. 2-4, 9). The welded seam 4 can be made both round (Fig. 2), for example, repeating the contour of the edge of the rounded element of the forming shell 1, or in the form of a set of segments located at an angle to each other (Fig. 3), forming a broken line, or a polygon (Fig. 4). In this case, the configuration of the formed common weld 4 is determined, for example, by the contour of the wire heating element, which has a thermal effect on the elements of the package during the formation of the common weld 4.

To improve the consumer properties of the package and the formation of a uniform in thickness and width common weld 4, it is advisable to make the forming parts of the package - the shell 1, the corresponding forming element 3 and the membrane 2 from the same materials. It is advisable to choose the thickness of the polymer material up to 700 microns.

At the same time, with the formation of a welded seam 3, a gaseous medium is pumped into the inside of the package under the required pressure. The force of such pressure is also determined by the characteristics of the packaged products, is calculated experimentally in each case and is assumed to be necessary to preserve the external shape of the package when exposed to an external influence on it during manipulations with it.

When the membrane 2 is perforated (Fig. 6), one source of a gaseous medium is sufficient. In the case of making the membrane 2 continuous (Fig. 5), several sources of supply of a gaseous medium can be used in each zone of the package - between the membrane 2 and the shell 1 and between the membrane 2 and the counterforming element 3, for example, to create zones with different pressures.

Thus, it is possible to carry out the simultaneous packaging of several dissimilar products and goods, both food and non-food, even in the absence of their primary packaging in inexpensive packaging with improved consumer properties, which ensures the integrity of the packaged products during storage, transportation and other manipulations and the possible external impact on the packaging due to falls, impacts on other goods, due to the division of the inner space of the packaging into separate zones with an unchanging or rapidly recovering configuration of their volume and shape in the process of using packaging with packaged products and goods in the commodity circulation.
