Description

The purpose of this utility model is to provide a packaging box as defined in the initial part of paragraph 1 of the formula of the utility model.

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

For example, liquid-tight and leak-proof packaging that can be carried and stacked is required in the food industry for packaging meat and fish. In addition, packaging for meat and fish should 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 one package can have up to 20 kg of weight, and the boxes are usually folded together, usually in 10 layers. Consequently, another important issue is the structural rigidity of the packages and their resistance to compression.

According to the prior art, leak-resistant packaging made of expanded polystyrene or molded plastic, filled from above and stacked, are often used for storing and transporting meat. Plastic boxes are pre-filled with holes for carrying, however, such boxes require a lot of storage space before use and, therefore, incur additional costs. Also, discarding them after use is problematic. In addition, the materials used in production are not recyclable, therefore, from the point of view of environmental protection, the use of the packages described above is not environmentally friendly.

Liquid-tight packaging made from corrugated paperboard is also known in the art; one such solution is disclosed in utility model FI 10658. A solution provided with corner folds, essentially known in the art, is used in the above publication. The disadvantage of this structure is the outer smooth structure of the end. When lifting and handling boxes it is impossible to get the necessary grip.

Another problem with corrugated cardboard boxes with liquid-tight corners and provided with corner folds is that due to the large weight of the boxes, the end of the specified box protrudes outwards. As a result, when stacking another box on top, she tries to pin down the box below. This greatly hinders the handling of the box, in particular, during its lifting. 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 sufficiently tight locking of the long sides and, therefore, the free structure has a lower load capacity.

Flow-resistant solutions made of corrugated cardboard and filled from above, 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. This is a significant drawback 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 drawbacks of the prior art.

The technical result is reliability when stacking several packaging boxes.

With the utility model solution, it is possible to obtain an innovative carrying handle, acting as a carrying grip, with which it is easy to lift and move packing boxes. Said carrying handle according to the utility model is particularly well suited to a completely liquid-tight and leak-proof packaging box. In this case, moving the package along the useful model remains simple even when it is fully loaded. The structure of the carrying handle, in addition to the grip, also simultaneously acts as an element of the rigidity of the packaging structure. This carrying handle blocks the end of the package in its shape and also stiffens the structure of the end. Thus, the packaging retains its shape, even if several packaging layers are stacked on top of each other.

The invention relates to corrugated cardboard packages and their blanks that are mechanically or manually molded without an adhesive, resistant to liquids and leaks from the inside, and resistant to moisture and liquid from the outside. These packages are stackable one on top of the other; they do not have flap valves that are unfavorable for packaging; instead, they have short shoulders for stacking.

More precisely, the utility model differs as indicated in the claims.

Further, the utility model is described in more detail with the aid of an embodiment with reference to the accompanying drawings, in which:

FIG. 1 - packing box blank according to the utility model;

FIG. 2 - unfolded packing box according to the utility model;

FIG. 3 - part of the blank packaging box, which shows the handle for carrying;

FIG. 4 - part of the blank packaging box, which shows the handle for carrying;

FIG. 5 - part of the packaging box with the assembled carrying handle.

FIG. 3-5 shows the end portion of the packaging box according to the utility model and the structure 13 of the carrying handle acting as a grip made therein. Said packaging box is an integral structure made of corrugated cardboard for mechanical or manual molding without adhesive. The packaging box blank comprises a fold line 17 between the vertical surface 3 of the short side and the stacking plane 4, a crevice slot 23 formed in the vertical surface 3, and also protrusions for the carrying handle 13 acting as a grip. In addition, the workpiece contains a double fold line (16) between the stacking plane (4) and the stacking bottom side (5).

In the simplest version, the carrying handle 13 is formed by one protrusion 13.1 made on the outer end of the bottom side 5 of the stacking plane. Most preferably, the carrying handle structure 13 is made of two protrusions 13.1 and 13.2. According to FIG. 1-5, the protrusion 13.2 of the carrying handle 13 is made on the vertical surface 3 of the short side of the packaging box, above the fold 23 for folding. When bent, the said protrusion 13.1 of the handle 13 for carrying the packing box forms the lower part of the grip of the carrying handle, and the protrusion 13.2 forms the upper part of the said grip. This structure 13 carrying handles, acting as a grip, is the essence of the utility model, while this structure, additionally being a carrying grip, also blocks the vertical surface 3 of the short side of the packaging box and the stacking plane 4, 5, and provides rigidity to the end structure.

FIG. 1 and 2 show a particularly preferred embodiment of the utility model for forming a carrying handle and for use on a liquid-tight packaging box. The box has a base surface 1, a foldable surface 2 long sides, a vertical surface 3 short sides, a short side stacking plane 4, a short side stacking plane 5 bottom, and folds 6 and 7 to obtain a liquid-impermeable structure of corners. Also, friction tongues acting as brake shoes of 12 corners ensure that the indicated structure does not open inside the box; they lock the double-bent shoulder 10 between the sides 4 and 5. The 8 sides of the long sides that are cut to shape are also the essence of the utility model, while the sides that have been cut to shape give rigidity to the long side structure even at the filling stage of the box, however, making it easy to fill the box.

According to the above, the packaging of FIG. 2, formed mechanically or manually without an adhesive, obtained from a die-cut blank on which the packaging surfaces 2, 3, 4, 5, 6, 7 form a liquid-tight and leak-proof structure. The folds 6 and 7 are bent against each other on the inner surface of the vertical surface 3 by inclined bend 18. The inner end, point A, of the inclined line of the conical bend 21 is connected to a straight fold 22 between the surface 1 of the base and the vertical surface 3. Inclined at the outer end at point B is 5–20 mm relative to the fold 22. Thus, the end surface in the vertical direction forms an inclination of the cone-shaped form to the inside of the box, in this case the length of the box at the top hour These (point B) are shorter than the length of the base part (point A).

Preferably, the solution is in the form of a carrying handle 13 with a tapered fold 21 inclined towards the inside of the packaging box. It is particularly preferable to use together with a tapered bend 21 hook locks 9 on the horizontal plane. This combination hardens the end side of the packaging box and locks it, while at the same time functioning as a handle for carrying the packaging box. The liquid-tight packaging box is finally blocked when the fold 17 between the end sides 3 and 4 is bent and the protrusion of the carrying handle 13 is pressed into the slot 23 formed by the cuts.

The purpose of the utility model is to obtain a new and essentially more technologically advanced packaging box solution, especially impermeable to the box fluid. According to the prior art, the solution in the form of a carrying handle 13, acting as a grip on a utility model, has not been used before. In particular, the novelty of the utility model lies in the fact that, most preferably, it combines the solution in the form of corner folds with a cone-shaped structure 21 and a hook closure 9 of the horizontal type. Thus, the box structure is blocked and, at the same time, the capture structure for a liquid-tight packaging box is obtained.

The person skilled in the art will understand that the utility model is not limited to the embodiments presented and may be modified within the scope of the attached utility model formula.
