Definitions

• the object of the present invention is a packaging box as defined in the preamble of claim 1 and a detachable lid structure integrated into it.
• packagings Numerous different packagings are known in the packaging sector, which have been developed for differing needs.
• the construction of packaging is primarily determined by the intended use. However, other aspects related to the manufacture and use of a packaging must also be taken into account in the design of the packaging.
• the handlability of packagings that must be liquid-tight and leakproof is in most cases a problematic point, especially when moving and stacking them when they are packed.
• liquid-tight and leakproof packagings that can be carried and stacked one on top of another are needed in the food industry for packing meat and fish.
• the packagings of meat and fish must be made of hygienic materials, i.e. the material must be approved for coming into contact with fatty food.
• boxes for meat and fish must be very firm, because there can be up to 20 kg of weight in one packaging and boxes are generally stacked one on top of another generally 10 layers high.
• another essential problem has been the structural rigidity of the packagings and their stacking strength.
• leakproof packagings fabricated from expanded polystyrene or plastic pressed into shape, fillable from above and stackable one on top of another have often been used for preserving and transporting meat.
• such boxes require a large storage space before they are taken into use, and this incurs unnecessary costs. Also their disposal after use is problematic. Additionally, the materials used in manufacturing them are not renewable, so from an environmental perspective use of the packagings described above is not ecological.
• the aim of the present invention is to achieve a solution by means of which the drawbacks of prior art are avoided.
• a completely new lid solution can be realized.
• the lid solution is particularly well suited to a fully liquid-tight and leakproof packaging box. That being the case, handling of the packaging according to the invention remains easy also when heavily packed.
• the packaging retains its shape essentially unchanged, even though a number of layers are stacked one on top of another on top of it.
• the invention relates to corrugated board packagings, and blanks thereof, to be formed mechanically or manually without adhesive, that are tight against liquid and leaks from inside and also tight against damp and liquid from outside.
• the packagings are stackable one on top of another; they do not have lid flaps detrimental to packing but instead have short stacking shoulders.
• Fig. 1 presents a packaging box blank according to the invention.
• Fig. 2 presents the packaging box and lid according to the invention, when assembled.
• Fig. 3 presents a packaging box and a lid structure integrated into it.
• Fig. 4 presents a structure of the lid.
• the packaging box according to the invention is a one-piece, liquid-tight packaging box fabricated from corrugated board to be formed mechanically or manually without adhesive.
• the box has a base surface 1 , a folding surface 2 of the long sides, a vertical surface 3 of the short sides, a stacking plane 4 of the short side, an underside 5 of the stacking plane of the short side, and also bellows 6 and 7 for achieving a liquid-tight corner structure.
• Fig. 1 with these a packaging according to Fig. 2, formed without adhesive mechanically or manually, is obtained from one die-cut blank, in which packaging the surfaces 2, 3, 4, 5, 6, 7 form a liquid-tight and leakproof structure.
• the bellows 6 and 7 fold against each other onto the inside surface of the vertical surface 3 owing to the inclined fold 18.
• the invention relates to a packaging box and to a separate detachable lid structure 25 integrated into it.
• a shaped tongue 15 is formed on the outer ends of a stacking plane 4, and the corner 27 of the lid structure 25 and the flattening 28 formed in the corner is guided to slide under the shaped tongue
• the shaped tongue 15 is formed on the shoulders of the outside of the double-folded fold 10.
• the cut-to-shape sides 8 of the long sides are also essential to the invention, the cut-to-shape sides stiffening the structure of the long side and simultaneously functioning as a support for the detachable lid structure 25 when stacking boxes one on top of another.
• the shaped tongue 15 is folded into the horizontal plane from the crease 17 between the vertical surface 3 of the short side and the stacking plane 4 onto the surface 8.
• the corner 27 functions as a locking means of the lid structure in such a way that the flattening 28 of the corner 27 is pressed between the tongue 15 and the surface 8, locking into place by means of friction.
• the structure of the detachable lid 25 is essentially a planar sheet, the width and length of which varying according to the requirements. In most cases the width of the lid 25 is, however, in practice about as wide as the packaging box itself or at least as wide the width of the aperture itself.
• the length of the lid 25 is determined according to the tongue 15 in such a way that the corner 27 of the lid locks firmly under the tongue 15. In most cases the length of the lid 25 is the length of the inner edges between the stacking planes 4 and/or the length of the aperture between the double folds 16, or at least the length of the aperture of the packaging box itself.
• a transverse crease 26 over the lid in the direction of the short end side of the packaging box is formed in the center of the lid 25.
• This crease 26 facilitates installation of the lid 25 by guiding the flattening 28 of the corner 27 into position under the shaped tongue 15. In this way the structure is far simpler with respect to what is known in the art.
• the solution enables the use of an advantageous sheet lid and speeds up the lidding of a box.
• the solutions used earlier have been more complex and considerably more expensive to fabricate. A factor to be considered is that cost-efficiency is without question one of the most important competitive assets in the packaging industry.
• the integrated lid solution is well suited as a protective cover for leakproof and liquid-tight packagings.
• a particularly advantageous packaging box application is obtained, which comprises a rigid sheet to be installed under the shaped tongues 15 of the packaging box, the sheet functioning as a separate detachable lid structure 25.
• the packaging box comprises an inclined fold 18 between the liquid-tight corner bellows 6, 7.
• the box comprises an inclined conical fold 21 between the folding surfaces 2 and the corner bellows 7 in such a way that the folding line 21 is inclined with respect to the crease 22 between the base surface 1 and the vertical surface 3. In this way a cone structure inclining inwards into the box is obtained, by means of which the corners 27 of the lid structure lock extremely tightly to the packaging box.
• the packaging box comprises an integrated lid functioning as a separate structure 25. Together with the embodiment presented above, it forms an extremely good packaging box construction. It is obvious to the person skilled in the art that the invention is not limited to the embodiments presented above, but that it can be varied within the scope of the claims presented below.
