Description

[0001] Octagonal Food Container

[0002] The invention relates to light industry, namely to packaging means, in particular to containers for placing food products, and can be used for storing and transporting food products, prepared meals in cafes, canteens, restaurants, and at home.

[0003] The use of octagonal food containers allows, on the one hand, the use of standard sheet blanks, which are cost-effectively converted into volumetric products from a production point of view, and also, unlike standard quadrangular food containers, these octagonal containers have greater rigidity due to the addition of four ribs to the container.

[0004] A variety of containers are known from the prior art, for example, an octagonal cardboard container for packing fruits and vegetables is known (https: / / ru.freepik.com / premium-photo / dark-brown-retail-carton-container-packing-fruits-vegetables-isolated-white_20319379.htm), the main disadvantage of which is the extremely low rigidity of the container walls, despite the octagonal base, as well as the impossibility of using the lid together with the container, since it cannot be tightly attached to it.

[0005] Also known in the prior art is a box (FEFCO Box 0352) made of corrugated cardboard (https: / / www.utupack.ru / 0352 / ), consisting of an octagonal body and two self-draining lids. A disadvantage of this container is its lack of tightness, making it unsuitable for use with liquid food products. Also known in the prior art is a cardboard container laminated with rigid thermoplastic film (RU 2792268, July 23, 2019), which is made of cardboard with a thermoplastic film applied over it. The main disadvantage of this container is the difficulty of on-site assembly without specialized equipment (a vacuum machine with heated film), as well as the impossibility of tightly closing it with an appropriate lid.

[0006] The objective of the invention is to develop an octagonal food container that eliminates the above-mentioned disadvantages.

[0007] The technical result of the invention consists in increasing the rigidity of a container closed with a lid while reducing the possibility of leakage of liquid food products when the container is overturned.

[0008] The technical result is achieved by using an octagonal food container according to the invention. The octagonal food container comprises a container and a lid, wherein the container is made with an octagonal base, the opposite sides of which are pairwise equal and parallel, and the side surfaces are four pairs of isosceles trapezoids, the smaller bases of which are connected to the octagonal base of the container, while the larger bases of said trapezoids of the container are connected to a horizontal shelf of the container, the outer edge of which is bent downwards; the lid is made along the edges with a horizontal shelf, which repeats the said horizontal shelf of the container and has an outer edge that is bent downwards, the said lid on each side contains a lock in the form of recesses, one of which recesses rests against the inner surface of the side surface of the container, and the other is hooked onto the outer edge of the horizontal shelf of the container.

[0009] An additional feature is that the said recesses are made in the lid on the side at the point where the side of the lid transitions into the horizontal shelf of the lid, as well as in the folded edge of the lid in such a way that the given recess on the said edge engages with the outer edge of the horizontal shelf of the container.

[0010] Fig. 1 shows a food container according to the invention.

[0011] Fig. 2 shows a section of container A-A from Fig. 1.

[0012] Fig. 3 shows a development of the container capacity, where the fold line is shown in blue and the cutting line in green.

[0013] Fig. 4 shows a top view of the container lid according to the invention.

[0014] The following positions are indicated on the figures: 1 - container; 2 - lid; 3 - octagonal base of the container; 4 - side surfaces of the container; 5 - right triangles; 6 - horizontal shelf of the container; 7 - outer edge of the horizontal shelf of the container; 8 - side of the lid; 9 - horizontal shelf of the lid; 10 - bent edge downwards; 11 - a lock in the form of two recesses for connecting the lid to the container; 12 - rim on the lid.

[0015] An octagonal food container according to the invention comprises a container (1) and a lid (2).

[0016] The container (1) is made with an octagonal base (3), the opposite sides of which are pairwise equal and parallel, and the side surfaces (4) are four pairs of isosceles trapezoids, the smaller bases of which are connected to the octagonal base of the container (3).

[0017] In Fig. 3 there is additionally shown a development of the container capacity, where the fold line is shown in blue, and the cutting line in green. The said lateral sides of adjacent trapezoids are connected by the hypotenuses of right triangles (5), and the large bases of the said trapezoids of the container and the legs of the said triangles of the container (5) are connected to a horizontal shelf (6), the outer edge (7) of which is bent downwards. In this case, the triangles (5) are connected to each other by the remaining legs. In the assembled container capacity (1) is made in such a way that the lateral surfaces (4) are four pairs of isosceles trapezoids, the smaller bases of which are connected to the octagonal base of the container (3), and the large bases of the said trapezoids of the container are connected to the horizontal shelf of the container (6), the outer edge (7) of which is bent downwards.

[0018] Fig. 4 shows a lid (2) of a container according to the invention. The lid (2) is convex, the lateral sides of which widen towards the edges. The lateral sides of the lid (8) transition into a horizontal shelf of the lid (9). In this case, Fig. 2 shows where said horizontal shelf of the lid (9) repeats said horizontal shelf of the container (6) and contains an outer edge of the lid (10), which is bent downwards, that is, the outer perimeter of the lid (2) repeats the outer perimeter of the container (1).

[0019] The lid (2) comprises a lock (11) made in the form of two recesses on each side of the lid (8) and the bent edge of the lid (10) for connecting the lid to the container. It is obvious to a specialist that the convexity of the lid may repeat the outer perimeter of the lid, or may be made in any way. In Fig. 4, the convexity of the lid is shown with a rectangular perimeter. In this case, the said recesses of the lock (11) are made in the lid on the side (8) at the transition of the side of the lid (8) into the horizontal shelf of the lid (9), as well as in the bent edge of the lid (10) in such a way that this recess on the said edge (10) is engaged with the outer edge of the horizontal shelf of the container (6).

[0020] For rigid positioning when installing containers on top of each other, the container (1) and lid (2) are provided with a protrusion (12) and a corresponding identical recess on their surfaces.

[0021] The container is assembled from sheet cellulose paper, the unfolded form of which is shown in Fig. 3, with a protective heat-sealable coating. To produce the blanks, punching and creasing are performed. The individual blanks are then assembled using sets of punches and dies, and the welding is accomplished thermally by heating the heat-sealable coating and applying pressure.

[0022] Increasing the rigidity of a container closed with a lid consists of making a lock (11) in the form of two recesses on the lid, one of which rests against the inner surface of the side surface of the container (4), and the other is hooked onto the outer edge (7) of the horizontal shelf (6), forming a strong connection, which also makes it possible to reduce the possibility of leakage of liquid food products when the container is overturned.

[0023] It should be noted that the lid can be of any height and have geometric deviations from those shown in the illustrative figure, within the scope of the described prior art. Thanks to assembly by thermally heating the heat-sealable protective coating, the finished product requires no assembly and is delivered ready for use. Furthermore, this assembly method eliminates the need for adhesives, reducing the overall cost and enhancing its economic appeal.

[0024] Due to the design of the forming side walls (4) of the container (2) in the form of trapezoids, the container (2) has a smaller base at the bottom and a larger one at the top, thus the containers have the ability to fit tightly into each other, reducing the storage and transport volume during storage and delivery of ready-to-use containers.

[0025] The clear plastic lid also provides a large viewing area, which is important for product presentation when it is packaged in a container.
