Description

TECHNICAL FIELD

The invention generally relates to the field of packaging for the transport of materials, for example cardboard boxes, and can be more specifically defined as a package made by folding all the parts that are connected to a central part to form a body and parts of the package that represent its interior or external equipment, for example, carrying handles.

TECHNICAL PROBLEM

The technical problem solved by the present invention is a design solution for creating a transport package for packaging pizza slices obtained by cutting a round pizza into six pieces, while ensuring that the pieces do not stick to the package or other pizza slices; packaging that retains its shape when packing hot slices of pizza; packaging that is quickly and easily formed, filled and transported and stored in a flat form, which is much more efficient, resulting in low transportation costs; packaging that, once formed and filled, takes up a smaller footprint and can be carried with a carrying handle or fit into commonly used pouch sizes; packaging that can be easily taken from the point of sale, which helps expand the target customer group; packaging in which pizza slices remain warm longer and the influence of moisture is reduced; packaging that is quickly produced by machine with maximum use of surfaces for placing pizza slices; packaging that can be printed both on the outside and on the inside so that on the inside the packaging meets all sanitary and microbiological safety requirements; packaging that is transported flat and is formed by simply folding up the side panels at the packaging location; packaging that can be disinfected, if necessary, using processes approved for use with food; packaging, which is competitive in comparison with existing cardboard or PET packaging in terms of product price, and at the same time, on the inside, fully satisfies all requirements, but from the aesthetic side does not reveal the structure of the cardboard used to form the packaging, and also meets the requirements in regarding protection, storage, transportation and environmental functionality, including current standards and regulations in this area.

BACKGROUND OF THE ART

According to the applicant, today various design solutions are used for transport packaging for pizza.

It is generally accepted that packaging material is the most important element when creating packaging design and practically determines the choice of technology for its production. It is these facts that have influenced the powerful development of cardboard packaging in addition to polymer materials, which in combination with this provides safer packaging in lightweight cardboard boxes made of special cardboard coated with a polymer layer resistant to temperature, humidity, etc.

In modern practice of high-production pizza factories, the packaging process is divided into packaging of pizza slices and packaging of whole pizzas. A pizza slice is made by cutting a pizza by dividing a 360° angle centered in the middle of a circular pizza into four, six or eight pieces. In other words, a slice of pizza occupies the area formed by the angle between the radius of a circle, obtained by dividing the angle by 360° with its center at the center of the pizza, and the arc of a circle above this angle, forming the end of the pizza. Thus, a slice of pizza has the approximate shape of an isosceles triangle with sides that are the radii of the circle, and the third line is not a straight line, but an arc of a circle over that angle. The most common angles formed by division are 90°, 60° and 45°. The diameters of pizza edge circles commonly used are 28 cm, 32 cm, 37 cm, 40 cm, 42 cm, 50 cm and 55 cm.

The problem with packaging pizza slices is that the low price of a slice of pizza sharply increases the price of packaging that meets sanitary and microbiological safety requirements. In terms of economy, the single slice pizza box is rarely used and the boxes that are known in the market have evolved towards enlarging the base of the box to accommodate more pizza slices or a whole pizza. Such solutions are impractical because the large footprint of the box is impractical to carry and quickly loses temperature, so most pizza makers rely on delivery, which further increases transportation costs and delivery itself is difficult in areas inaccessible to cars, bicycles, scooters, and boxes. not convenient for public transport. On the other hand, cardboard boxes weighing up to 450 g/m2, which can be printed on offset presses, often do not have the strength to maintain their shape when packaged, and corrugated cardboard requires different printing technologies with much lower print quality, they are much bulkier, and therefore transportation costs increase many times over.

A search of patent and non-patent documentation did not reveal any documents that solve this technical problem.

The solution of the same applicant is known from the patent RS 58588 B1, published on 05/31/2019, with the title “Holder for a self-folding pizza box”, which shows a box for packaging pizza slices, consisting of a holder formed by spacers superimposed on each other and a box into which the holder is inserted. This solution makes it possible to pack pizza slices one on top of the other, and the holder retains its strength when packing the slices, and with its strength it gives strength to the box in which it is inserted. Pizza slice sizes vary depending on whether the round pizza is divided into four, six or eight slices. A disadvantage of the invention is that the carriers must be formed manually during packaging of the pizza slices, which requires much more time compared to the formation according to the present invention, which has a simpler structure and has a carrying handle.

DISCLOSURE OF THE INVENTION

The novelty of the invention is that the box for packaging pizza slices is formed by simply folding the side panels upward and takes the form of a box with partitions, where two slices of pizza can be placed on each partition and on the bottom base of the box. The box is made in the form of a prism, the bases of which are diamond-shaped and inside which there are two partitions, it is closed with the help of valves and locks with the possibility of inserting a handle for carrying the box. This allows manufacturers to form a box in a matter of seconds, with the base of the box being one-third the size of the pizza's surface, and stacking the slices on top of each other allows the pizza to remain warm and much easier to carry.

The essence of the invention is that such a flat box shape, which is transported to the pizza manufacturer and stored by him, is many times smaller in volume than known corrugated cardboard boxes, and thus the transportation costs are significantly lower. It is also a feature of the invention that the pizza slice dividers are formed by folding the panels upward in a position ready for filling the box, which reduces the box formation time. The pizza slice dividers are retracted into the interior of the box relative to the outer edges of the filling opening, allowing the arcuate sides of the pizza slices to stack on top of each other. In this way, the elastic properties of the dough are used in terms of tension on the inner sides of the box, which further enhances its locking. The present invention makes it possible to reduce the volume of an unmolded box by 5-6 times through the use of bulk cardboard with a thickness of 0.4-0.7 mm, which significantly reduces the cost of transportation and storage. The present invention makes it possible to produce a box from corrugated cardboard, as well as from cardboard with a thickness greater than 0.8 mm, as well as from cardboard with a protective layer, and it can be disinfected for microbiological protection.

The essence of the invention is that by placing the box in the oven, the pizza can be heated to the temperature recommended by the manufacturer of the cardboard or polymer layer. The box can be stored in the refrigerator, and the used box takes up much less storage space in trash containers.

The essence of the invention is that in this way it is possible to pack pizza slices one on top of the other, and the box retains its strength when packing hot slices.

The essence of the invention is that such a folded blank allows a box with specified characteristics to be produced by machine, printed, cut along cutting lines, pressed along folding lines and glued to a mold into sheets ready to be folded up and formed into a box. In the first step, a sheet is printed with or without a resin layer, a tool is cut along the outer contour of the printed sheet in the machine, and cutting lines and folding lines are also made, and then the molded folded workpiece is placed into the gluing machine. The molded folded blank ensures that all fold lines around which the glued parts can rotate are parallel to the direction of movement of the box in the machine, allowing the gluing process to be carried out on well known machines in the printing industry. First, glue is applied linearly to the marked area of the upper part of the molded folded blank, parallel to the direction of movement through the machine, and the marked part is glued in one pass. After this, the resulting form is turned so that the lower flat part of the glued form is turned upward, and it is returned to gluing. The adhesive is then applied linearly to two marked locations on the glued form that are parallel to the direction of travel through the machine. In one pass, glue is first applied, the first marked part is glued, and the second marked part is glued on top of the first. The essence of the invention is that the flat box shape thus formed is easily transported and stored and can be formed by manually bending the side panels upward to form a box with partitions with the possibility of inserting a handle. The box retains its strength during transportation, the pizza slices retain heat, and the end consumer can use it elegantly.
