Transformable pizza box with tear-off strip system

Abstract

The utility model relates to packaging for food products, primarily for pizza. A transformable box comprises a lower part (1) and an upper part (2) connected along a fold line to form a rear wall (3). On the outer surface of the rear wall (3), along the line connecting the upper and lower parts, a first tear-off tape (4) with a tongue (5) for separating the upper part (2) from the lower (1) is located. The upper part (2) has vertical sides (6) along the perimeter. On the upper part (2) a second group of tear-off tapes (7) is located in the amount of 6, 8 or 12, diverging radially from the geometric center (8) to the edges and continuing onto the vertical sides (6). Each tape (7) of the second group is provided with a tongue (10) for gripping, located on the outer edge at the lower border of the vertical side (6). All tapes (7) converge at the center (8), forming a central unit (9). When closed, the box has no holes, which ensures that the pizza remains warm during delivery.When using, first separate the upper part (2) from the lower part (1) using the first tape (4), then separate the sectors (11) using the tabs (10). Each separated sector (11) comprises a flat part (12) and a vertical edge (13) located only along the outer edge of the sector, and represents a ready-made plate for a slice of pizza. The technical result is to ensure a two-stage transformation of the packaging into individual plates with smooth tear edges, preservation of the pizza's heat until opening, and a vertical edge along the outer edge of each plate. 3 ill.

Description

[0001] 1. Field of technology to which the utility model relates

[0002] This utility model relates to food packaging, primarily for pizza, and can be used in the premium delivery segment of finished products, as well as in the restaurant and catering industries. The box design allows it to be transformed into individual plates for each slice of pizza.

[0003] 2. State of the Art

[0004] Various food packaging designs are known in the art, particularly for pizza. Traditional pizza boxes are cardboard parallelepipeds consisting of a base and a lid connected to the back wall along a fold line.

[0005] The GreenBox pizza box is known for having perforations on the lid that allow the lid to be divided into four sections that can be used as plates (analogue).

[0006] The disadvantage of this analogue is the following:

[0007] 1. Perforations compromise the integrity of the cardboard's insulating layer, leading to accelerated cooling of the pizza due to the uncontrolled release of warm air through the perforations.

[0008] 2. Perforation does not provide a perfectly straight tear line and creates uneven edges on the resulting plates.

[0009] 3. The solution is limited to a fixed number of sectors (only 4), which does not correspond to the standard pizza cutting into 6, 8 or 12 slices.

[0010] 4. The known solution does not provide a mechanism for separating the upper part from the lower part while preserving the vertical edges that could form a plate with edges.

[0011] 3. Disclosure of the essence of the utility model

[0012] The technical problem solved by the utility model is to create pizza packaging that provides:

[0013] maintaining the thermal insulation properties of the box until it is opened (unlike analogs with perforation, where heat is lost immediately);

[0014] separating the top part of the box from the bottom while maintaining the vertical sides on the top part;

[0015] subsequent division of the upper part into separate sectors, each of which represents a finished plate;

[0016] possibility of obtaining the number of sectors corresponding to the standard pizza cutting (6, 8 or 12).

[0017] The technical result of the utility model is:

[0018] providing a two-stage transformation of the packaging into individual plates with smooth tear-off edges and maintaining a vertical edge along the outer edge of each plate;

[0019] Maintaining the integrity of the insulating layer of cardboard until the moment of use, since tear-off tapes do not create through holes in the box, unlike perforation, which allows you to keep the pizza hot longer.

[0020] 4. Brief description of drawings

[0021] The essence of the utility model is explained by drawings, where:

[0022] Fig. 1 shows the box in a closed state (rear view);

[0023] Fig. 2 shows the upper part of the box after separation from the lower one (top view);

[0024] Fig. 3 shows a separated sector of the upper part of the box.

[0025] Fig. 1 - Box in closed state (rear view)

[0026] Fig. 1 shows a box containing:

[0027] lower part (1);

[0028] the upper part (2), connected to the lower part along the fold line to form the back wall (3);

[0029] the first tear-off tape (4) located on the outer surface of the back wall (3) along the connection line of the upper and lower parts;

[0030] the tongue (5) of the first tear-off tape protruding beyond the lower edge of the back wall (3).

[0031] The first tear-off strip (4) is designed to separate the upper part (2) from the lower part (1) by pulling the tab (5). When closed, the box has no through holes, ensuring heat retention.

[0032] Fig. 2 - The upper part of the box after separation from the lower one (top view)

[0033] Fig. 2 shows the upper part (2) of the box after separation from the lower part, containing:

[0034] flat surface;

[0035] vertical sides (6) located along the perimeter of the upper part;

[0036] the second group of tear-off tapes (7), located radially from the geometric center (8) to the edges of the upper part and continuing onto the vertical sides (6);

[0037] central node (9) of convergence of all tear-off tapes (7) in the geometric center (8);

[0038] Grip tabs (10) located on the outer edges at the lower border of each vertical side (6).

[0039] The number of tear-off tapes (7) of the second group corresponds to the number of sectors into which the upper part is divided, and is selected from the series: 6, 8 or 12.

[0040] Fig. 3 - Separated sector of the upper part of the box

[0041] Fig. 3 shows a separated sector (11) of the upper part of the box, containing:

[0042] a flat part (12) having a shape corresponding to a slice of pizza;

[0043] vertical edge (13), located only along the outer edge of the sector (11).

[0044] The remaining edges of the sector (11) are straight tear lines. The separated sector (11) is intended to be used as a plate for a pizza slice.

[0045] 5. Implementation of the utility model

[0046] The transforming box is used as follows.

[0047] Stage 1 (transportation and storage): When closed, the box has no holes, as the tear-off strips (4) and (7) are located either inside the material or on the surface, but do not compromise the integrity of the cardboard. This ensures that the pizza retains its heat during delivery, unlike perforated boxes, where heat is lost through the holes.

[0048] Step 2 (Separating the Top from the Bottom): The user pulls the tab (5) of the first tear-off tape (4) located on the back wall (3) on the outside of the box. The tape (4) cuts the material of the back wall, causing the top part (2) to completely separate from the bottom part (1), while maintaining the vertical edges (6).

[0049] Stage 3 (Dividing into plates): The user takes the separated top section (2) and, holding it, pulls one of the tabs (10) located on the vertical edges (6). The corresponding radial tear tape (7) cuts the top section material from the edge of the edge, through the vertical edge and along the plane of the lid to the central unit (9), separating the sector (11).

[0050] Stage 4 (Use): The separated section (11) is a ready-made pizza plate with a flat part (12) and a vertical edge (13) along the outer edge to prevent food from sliding off. The remaining sections are separated in a similar manner.

[0051] The number of radial belts (7) can be selected as 6, 8 or 12 depending on the standard pizza cutting.

[0052] The box is made of cardboard or micro-corrugated cardboard suitable for contact with food products. Tear strips (4) and (7) are made of polymer material and are glued inside the box material or glued to the surface according to their intended purpose. When closed, they do not create through holes.
