Description

FOOD PACKAGING AND FOOD PACKAGING BLANK ENGINEERING

The present invention relates to food packaging blanks and food packaging. In particular, the invention relates to food package blanks and food packages having a flap that is openable to form a spout.

BACKGROUND

Food containers are generally provided with a pouring opening for pouring the contents out of the package. A spout is most often formed at the top of the narrower side of the package. The pouring opening can be formed by a flap which is - separated from the side of the package by perforation. By pressing the flap with your finger, the flap folds inside the package, forming a pouring opening. Alternatively, the side of the package may have a complex structure that is twisted outward into a spout.

The problem with the flaps of the flaps is that the flap may come off during use and drip inside the package, making it impossible to close the package. Since the pouring opening is not formed right up to the top corner of the package, food remains inside the package in the pocket formed by the top corner. Therefore, it is difficult to completely empty the package. The flap folded inside the package also prevents the contents from being poured out. Tipping models, on the other hand, are complex and more expensive to manufacture and consume up to twice the amount of board. It is an object of the present invention to provide a = 20 food package blank and a food package formed therefrom which solves at least N parts of the above-mentioned problems.

The flap 50 extends from the cover flap section 120 to the side wall section 110. The flap 50 is hinged to the cover flap section 120 so that when closed the flap 50 covers a portion of the cover flap section 120 and the side wall section 110 and exposes an opening 90 extending from the cover flap section 120 to the side wall section 110.

The flap 50 may extend from one cover flap 31 of the N cover flap portions 120 comprising the plurality of cover flaps 11, 21, 31, 41 to one side wall 30 of the S 25 side wall portion 110 comprising the plurality of side walls 10, 20, 30, 40. Thus, when closed, the flap 50 covers part N from one cover flap 31 and one side wall 30 and when open exposes an opening 90 s extending from one cover flap 31 to one side wall 30.

S According to one embodiment, the blank 100 comprises a tongue 60 connected to the side wall section 110 by a fold 61 extending in the first direction. S 30 By means of the tongue 60, the edges of the side wall section 110 extending in the first direction can be joined to each other.

Figure 2 shows = a food package blank 100 according to one embodiment. The blank 100 comprises a side wall section 110, a lid flap section 120, a bottom flap section 130 and a flap 50 which is openable. The side wall section 110 comprises a first side wall 10, a second side wall 20 connected to the first - side wall 10 by a fold 15, a third side wall 30 connected to the second side wall 20 by a fold 25, and a fourth side wall 40 connected to the third side wall 30 by a fold 35, which folds 15, 25, 35 extend in the first direction. The lid flap section 120 comprises a first lid flap 11 connected to the first side wall 10 by a fold 13, a second lid flap 21 connected to the second side wall 20 by a fold 23, a third lid flap 31 connected to the third side wall 30 by a fold 33 and a fourth lid flap 41 connected to the four to the side wall 40 by a fold 43 which folds 13, 23, 33, 43 extend in a second direction transverse to the first direction. The bottom flap section 130 comprises a first bottom flap 12 connected to the first side wall 10 by a fold 14, a second bottom flap 22 connected to the second side wall 20 by a fold 24, a third bottom flap 32 connected to the third side wall 30 by a fold 34, and a fourth bottom flap 41 connected to the fourth side wall 40 by a fold 44 which folds 14, 24, 34, 44 extend in a second direction transverse to the first direction. The flap 50 extends from the third cover flap 31 to the third side wall 30, which - the flap 50 is hinged to the third cover flap 31 so that when closed the flap 50 covers part of the third cover flap 31 and the third side wall 30 and exposes an opening 90 extending from the third cover flap 31 to the third side wall .

Figure 2 shows that the flap 50 comprises a first portion 51 which = when the flap 50 is closed covers a part of the third cover flap 31 and a second portion 52 which N 25 - when the flap 50 is closed covers a part of the third side wall 30. 5 it ] The first portion 51 of the flap 50 may be separated from the cover 70 by a cut. I Cuts can be made without fasteners to the cover. Thanks to the cuts, the flap 50 a Ko. _ can be easily lifted to expose the opening 90.

S = Alternatively, the first portion 51 of the flap 50 may be separated from the cover 70 O 30 - for example by perforation, a cutting line cut off by fasteners, i.e. punches, or> by grooving.

The cuts of the first portion 51 of the flap 50 may extend from the ends of the fold 53 of the flap 50 to the fold 33 connecting the third cover flap 31 and the third side wall 30.

The second portion 52 of the flap 50 may be separated from the side wall 30 by perforation. Due to the perforation, the second portion 52 of the opening 50 can be easily pressed inside the package to form a flap. Thus, opening the package does not require much force or tools such as scissors.

Alternatively, the second portion 52 of the flap 50 may be separated from the side wall 30 by, for example, a cutting line interrupted by fasteners, i.e. punches, or by grooving.

The first portion 51 of the flap 50 may be hinged to the second portion 52 - by a fold 54. The fold 54 may extend in a second direction. The ends of the fold 54 may extend, for example, 5-10 mm from the edges of the lid which are perpendicular to the fold 54.

According to one embodiment, the edge of the side of the second cover flap 21 extending in the first direction closest to the third cover flap 31 and the edge of the side of the fourth cover flap 41 extending in the first direction closest to the third cover flap 31 is substantially in the shape of the first portion 51 of the flap 50. Thus, the second lid flap 21 and the fourth lid flap 41 do not cover the flap 50 when the blank 100 is formed into a package. Once the blank 100 has been formed into a package, the edge of the lowest folded flap, for example the edge of the second lid flap 21, forms a sealing collar by cutting the first portion 51 of the flap 50 on the edges separated from the lid 70. Thus, the flap 50 can be easily raised and does not remain inside the package. In addition, the sides of the second lid flap 21 and the fourth lid flap 41 support the environment of the flap 50, whereby the pouring opening 90 formed therefrom is more durable.

O N The food package blank 100 may comprise a tongue 60. The tongue 60 may S be connected to the first side wall 10 or to the fourth side wall 40 by a fold 61, N 25 - extending in the first direction. By means of the tongue 60, the first side wall 10 can be connected to the fourth side wall 40 to form a package. N The tongue 60 may be pre-connected to the first side wall 10 or the fourth E side wall 40. The outer surface of the tab can be connected to the inner surface of the side wall. S In this case, it is possible to transport the blank in part - pre-glued, but still flat to form the base and lid. Thus, the base 80 and the lid 70 may be formed just prior to filling the food package 200 formed from the blank 100.

Figure 3 shows the formation of the bottom of the food package 200 from the blank 100 (right to left). First, the first base flap 12 and the third base flap 32 are folded over the fourth base flap 42. The second base flap 22 is then folded over the first base flap 12 and the third base flap 32 to form the base of the package 200.

Figure 4 shows the formation of the lid of the food package 200 from the blank 100 (from left to right). First, the first cover flap 11 and the third cover flap 31 are folded over the second cover flap 21. The fourth lid flap 41 is then folded over the first lid flap 11 and the third lid flap 31 to form the lid 200 of the package.

The food package blank 100 and the food package 200 may be made of cardboard, especially wet strength board. Cardboard is a lightweight packaging material that can be easily folded into a desired shape.

The inner surface of the food package blank 100 and the food package 200 may be coated. The coating can be, for example, a polyethylene coating (PE coating). Thanks to the PE coating, the food packaging formed from the blank has good grease and moisture resistance.

The tongue 60 can be connected to the first side wall 10 or the fourth side wall 40 and / or the bottom flaps 12, 22 32, 42 and the cover flaps 11, 21, 31, 41 can be connected to each other, for example by gluing. This achieves a tight and durable packaging.

Alternatively, the PE coating may act as an adhesive for the tongue 60, the bottom flaps 12, 22 32, 5 42 and the lid flaps 11, 21, 31, 41. The tongue 60 can be attached to the N first side wall 10 or the fourth side wall 40 by heat as the PE-S coating melts as it heats and forms a tight connection between the cover and the tongue.

N I 25 The food package 200 and the S package formed from the food package blank 100 can be used as a food package. However, packaging can also be used as packaging for other goods. 3> ”
