Description

The objective of this utility model is a packing box, as defined in the initial part of paragraph 1 of the utility model formula, and a detachable lid structure integrated into it.

In the field of packaging, there are many different types of packaging designed for different purposes. The design of the packaging is determined primarily by its intended use. However, when developing packaging, other aspects related to its manufacture and use should also be taken into account. It is difficult to obtain easy-to-handle packages that are impervious to liquids and resistant to leakage, especially when moving and stacking packaged packages.

For example, liquid-tight and leak-resistant packaging that can be transported and stacked are required in the food industry for packaging meat and fish. In addition, packaging for meat and fish must be made of hygienic materials, that is, the material must be approved for contact with fatty foods. In addition, boxes for meat and fish can be very rigid, since up to 20 kg of weight can be produced per package, while the boxes are usually stacked on top of each other, usually in 10 layers. Therefore, another important problem is the structural rigidity of the packages and their resistance to compression.

In the prior art, leak-proof packaging made of expanded polystyrene or molded plastic, filled on top and stackable, is often used for storing and transporting meat. However, such boxes require a lot of storage space before use and, therefore, cause additional costs. Throwing them away after use is problematic. In addition, the materials used in the production are not recyclable, therefore, from the point of view of environmental protection, the use of the packaging described above is not environmentally friendly.

Also, liquid-tight packaging made of corrugated board is known in the prior art, one such solution is disclosed in utility model FI 10658. A solution equipped with corner folds, essentially known in the art, is used in the above publication. The disadvantage of this structure is the integrated valve cover, making it difficult to fill the box on top. These valves interfere with the filling stage, both with manual filling and with the machine on the conveyor. In many industries conveyor

tapes do not provide space for vertical valves. Folding valves is difficult and may require additional expensive technology for existing conveyors. When manually deploying the box, the double valves, which extend along the entire length of the stacking planes, resist manual folding; moreover, it is difficult to add a simple cover to the indicated structure.

Another problem with corrugated cardboard boxes with liquid tight corners and corner folds is that due to the heavy weight of the boxes, the end of the box protrudes outward. As a result, when stacking another box on top, she tries to pin down the box below. This significantly impedes the handling of the box, in particular the handling of the lid below the box.

In some solutions with a liquid tight angle, the long sides are blocked by cardboard wedges between the end fold; however, this solution does not provide a sufficiently tight locking of the long sides and, therefore, the free structure has a lower carrying capacity.

Flow-resistant solutions made of corrugated cardboard and filled on top, more perfect in terms of shape preservation, were also used to stack and move food products with liquid contents, but in this case, the stacking planes of the upper parts are mechanically glued together. This is a significant disadvantage because it requires a separate, expensive packaging machine. In the manufacture of packages, their economic efficiency is extremely important, as well as, from a structural point of view, the functional connection and fixing of parts of packages.

The objective of this utility model is a solution with which you can eliminate the disadvantages of the prior art. With the utility model solution, it is possible to obtain an innovative lid solution. This lid is particularly suitable for fully liquid tight and leakproof packaging boxes. In this case, the handling of packaging according to a utility model remains easy even when fully loaded. In addition, the package retains its shape essentially unchanged, despite the fact that a number of layers are stacked on it.

The technical result of the claimed invention is to obtain easy-to-handle packages that are impervious to liquids and resistant to leakage, especially when moving and stacking packaged packages, i.e. provide structural rigidity and compression resistance.

The utility model relates to corrugated cardboard packaging and their preforms, formed mechanically or manually without the use of adhesive, impervious to liquids and resistant to leakage from the inside, and also resistant to moisture and liquids from the outside. The packages are stackable on top of each other and do not have lid valves that interfere with the package, but instead have short shoulders for stacking.

More precisely, the utility model differs indicated in the utility model formula. Further, the utility model is described in more detail using an embodiment with reference to the accompanying drawings, in which:

FIG. 1 - blank packaging box for a utility model;

FIG. 2 - a packing box and a lid according to a utility model in assembled form;

FIG. 3 - packaging box and integrated lid structure;

FIG. 4 - lid structure.

According to a utility model, the packing box is a one-piece, leak-proof packing box made of corrugated cardboard, formed mechanically or manually without adhesive. In FIG. 1 and 2, said box has a base surface 1, a foldable surface 2 of long sides, a vertical surface 3 of a short side, a stacking plane 4 of a short side, a bottom side 5 of a stacking plane of a specified short side, and corner folds 6 and 7 to obtain a liquid-tight corner structure. According to FIG. 1, the packaging of FIG. 2, made without adhesive mechanically or manually, is obtained from a single stamped blank, while in the indicated package, surfaces 2, 3, 4, 5, 6, 7 form a liquid-tight and leak-resistant structure. Corner folds 6 and 7 are bent against each other on the inner surface of the vertical surface 3, due to the inclined fold 18.

In FIG. 3 and 4, the utility model relates to a packaging box and a separate detachable lid structure 25 integrated therein. The essence of the packaging box is that the molded tongue 15 is made on the outer ends of the stacking plane 4, and the angle 27 of the lid structure 25 and the flattening 28 made in the corner is guided to slide under the molded tongue. The specified molded tongue 15 is made on the shoulders of the outer side of a double-bent fold 10.

The circumferentially-shaped sides 8 of the long sides are also the essence of the utility model, while the circumcised-shaped sides give rigidity to the long-side structure and at the same time act as a support for the detachable lid structure 25 when the stacked boxes are stacked on top of each other. The molded tongue 15 is bent horizontally from the fold 17 between the vertical surface 3 of the short side and the stacking plane 4 onto the surface 8. Together with the tongue 15 and the surface of the sides 8, the angle 27 functions as a locking means of the lid structure, so that said flattening 28 of the angle 27 is pressed between tongue 15 and surface 8, locked in place by friction.

The structure of the detachable lid 25 is essentially a flat sheet, the width and length of which varies, depending on the requirements. In most cases, in practice, the width of the lid 25 is equal to the width of the packaging box itself, or at least equal to the width of the opening. The length of the lid 25 is determined by the tongue 15, so that the angle 27 of the lid is tightly locked under the tongue 15. In most cases, the length of the lid 25 is equal to the length of the inner edges between the stacking planes 4 and / or the length of the hole between the double folds 16 or at least the length of the hole packing box. Additionally, a transverse fold 26 of the lid in the direction of the short end side of the packaging box is formed in the center of the lid 25. This fold 26 simplifies the installation of the lid 25 by directing the flattening 28 of the angle 27 to the position under the molded tongue 15. Thus, the structure is much simpler with respect to the prior art. Despite this, the solution allows the use of a preferred sheet cover and speeds up the application of the cover to the box. Previously used solutions were more complex and significantly more expensive to manufacture. It should be noted that economic efficiency provides a huge competitive advantage in the packaging industry.

In addition to the above, the integrated lid solution is suitable as a protective agent for leakproof and liquid tight packaging. In this way, a particularly preferred packaging box is obtained comprising a rigid sheet which is mounted under the formable tongues 15 of the packaging box, which sheet acts as a separate detachable lid structure 25. The packaging box contains an inclined fold 18 between the liquid-tight corner folds 6, 7. In addition to Moreover, this box contains an inclined conical fold 21 between the folding surfaces 2 and the corner fold 7, so that the fold line 21 is inclined relative to the fold 22 between the surface It has a base 1 and a vertical surface 3. Thus, a conical structure is obtained that is inclined inside the box, whereby the corners of the lid structure 27 are extremely tightly locked in the packaging box.

The packaging box now has an integrated lid acting as a separate structure 25. Together with the embodiment presented here, it forms an extremely convenient packaging box structure. It will be apparent to those skilled in the art that the utility model is not limited to the presented embodiments and may be varied within the scope of the utility model formula presented below.
