Packaging and process see how it is made

The invention relates to packaging and a method itt their production! In particular, the invention relates to packaging made from a combination of ateifen and blegaaMeti packaging materials.

Food, such as canned cocoa, cakes, rolls, bread, Ready meals (so-called T.V. Dinners) etc. arrive in general in Saaaelverpaokungen of 13 or 2 * pieces about shipping »The most common packaging is the ordinary cardboard made of cardboard bsw. Corrugated cardboard consists. Such boxes have the disadvantage «dad der The content of outside cannot be seen and that is why it is It is difficult to quickly identify the size, shape and type of content * Labels or inscriptions cannot convey the same precise knowledge of the content * as direct inspection.

The subject of the invention is therefore a packaging » in which the Paokgut sioh is in a container that surrounded by a plastic film and which thereby is known that the container has a base and has at least two vertical cross winds on the OrundfIMohe * whereby the height of the rare winds is essentially one Lingsabmeaeung des Paokguts, and defl the foil a shrunken foil "is the cross winds on one Prevents movement relative to Orundfliohe.

The «@trinohe shape of the one shown in the drawings !!« · packaging corresponds to a non-cubic law » angled parallelepipeds. However, the invention also includes Packaging that have the geometric shape of a cube or of another parallelepiped. The expression * rectangular "used in this description includes these geometric shapes. The expression "right-angled" also includes packaging that fails two or more adjacent right-angled parallelepipeds of different sizes or from one Consist of parallelepiped and a cube.

"Flexible packaging material" is used here and in the following understood a shrinkable packaging film. Worm-ear pollen is the most common conventional shrink films, but the invention also includes films that can be shrunk by means of solvents. The invention is not limited to a specific film or a specific type of film shrinkage. Crosslinked and stretched polyethylene and polypropylene films are common heat-shrinkable films. However, heat-shrinkable films made from rubber hydrocarbon, polyvinyl chloride and polyvinylidene chloride are also useful. Among those in the present context

The term "heat-shrinkable" used thus applies to all Pollen that shrinks on application of heat; under "elongated pollen" are both monoaxial and Understood biaxially oriented films.

As to the rigid packaging materials from which the containers of the present invention are made know include pressed cardboard, corrugated cardboard as well as general all cardboard-like materials made of paper or the like, as well as rigid products based on them of rubber or of organic synthetic plastics.

In Pig. 1 shows an embodiment of the invention in which the container 10 is made from corrugated cardboard is. The container 10 is formed by a corrugated cardboard blank which is and is previously folded and folded from a base area 13, vertical outer walls 14, horizontal Deokflächeη 16 and vertical partitions 15. The result is that the packaged goods 17 from the container is enclosed on four sides, so that only two sides open stay. The packaged goods 18, on the other hand, remain without a deodorant surface. A tubular film made of heat-shrinkable thermoplastic film surrounds the packaged goods units 17 and 18 and the container 10 completely, with only the opening 12 remaining open; on the opposite side of the packaging there is a similar one in the drawing unrecognizable opening.

Dl · Flg. FIG. 2 shows a package similar to that of FIG. 1 resembles. The container 20 consists of a base area · 2? , vertical outer walls 24, Deok walls 26 and vertical partitions 25. The middle part of the Papkgutee 28 is

additionally covered by an insert from the reverse undercut. This insert of utngekohrfc U-shaped cross-section consists of vertical walls 27 miu a? Top surface 29. A trunk film 21 wraps around the entire package so that only the openings 22 remain free. This package can be divided into three parts by cutting the film between the vertical walls 25 and 27 by means of a knife, similar to that shown in FIG. Lower use of the space between the walls 25 and 27 as a guide for the? Fesser this can be completely guided around and are used in cutting the Orundflache 25 = This procedure is illustrated in Fig. 8a, in the min knife 80 partially into the intermediate space is inserted between the vertical walls 27 and 25. 8b shows the separated third of the packaging. The film 21 normally adheres to the separated packaging and holds it together. This possibility of splitting a Samme1ver packaging especially valuable from each package into thirds 1st for retailers and restaurants that do not require in individual cases more than four or eight units such as cakes, pies, etc. _f at once.

Flg. 3 shows a package which is similar to that of FIGS. 1 and 2, but which can be divided into two halves. The container 30 consists of a base area 33, vertical outer walls 34, and horizontal cover walls 36 and vertical partitions 35 · The contents of the package 38 is equally distributed over the two enclosed volumes, which are formed by the orund surface 33 and the walls 34, and 36 are formed. An opening remains in the film 3I 32 open.

Pig, 4 shows a® packaging similar to that of FIG. 3, However, only one vertical partition 45 is provided.

In Pig, 5 the container 50 was folded so that a Top surface 56 is twice as long as the other. This makes it possible to retain 2/5 of the contents of the package when 1/2 is removed.

The heat-shrinkable film that envelops the packaged goods and the container can be a seamless tube into which the container with the packaged goods is pushed so that part of the tubular film protrudes on both sides of the packaging. The tube can also be formed by this be that one includes the container and the packaged product in a Follenbpgen and welds the overlapping foil ends. When the packaging is produced with the film edges 90 protruding beyond the sides of the packaging, as shown in FIG. 9, then the shrinkage can take place before the remaining parts of the film are shrunk tightly around the packaging and the packaged goods. The method for the step-by-step shrinking of a tubular film for wrapping a packaged item is described in the USA patent J 215 266. If the container and the packaged goods are completely enveloped, then gradual shrinkage is not necessary. Furthermore, the heating can be dispensed with if a film which is shrinkable in another way is used. For example, there is no need to heat when a solvent-shrink film is used.

The above-described packagings produced according to the invention have a compressive strength that is superior to conventional cardboard boxes made of corrugated cardboard with walls of higher test strength. Comparative comparisons were carried out in accordance with ASTM standard D642-47 on packaging according to FIGS. 3 and 4. The results obtained are summarized in Tables I and 2 below. In Table I , the packaged goods consisted of 24 227 g cocoa cans, which were arranged in a single layer so that all 24 cans were on the base of the container. In the case of TabeEe 2, the packaged goods consisted of 24 227 g cocoa cans, which were arranged in two layers of 12 cans each. Thus 12 cans stood directly on the base of the container, while a further 12 cans stood on the 12 lower cans. In both cases, the conventional cardboard box had walls made of corrugated cardboard with a test strength of 79.4 kg. The containers for the packaging according to the invention were made from corrugated cardboard with a test strength of 56.7 kg. The film was an irradiated, biaxially stretched polyethylene film approximately 38 meters thick .

The superior strength of the packaging according to the invention is evident from the above test results. The results reflect the addition · » lent strength, which results from the additional vertical partitions in the packaging according to PIg. 3 results. The reason why the packaging according to the invention has conventional cardboard packaging even surpass solid walls, is apparently due to the fact that the tightly fitting shrink film right walls press firmly against the packaged goods, thereby preventing these walls from moving sideways. the Walls cannot bulge easily because they are on one side from the shrink wrap and on the other Side are clamped by the packaged goods.

The modifications shown in FIGS. 1, 2 and 5 et ^ Jen essentially repetitions of the wrappings of Figures 3 and 4. This is also the case with these packagings will get the same skill improvement. If the strength needs to be increased even further, then can both on the outsides and in the In the middle further vertical cuts can be inserted. For example, in the case of the packaging according to FIG. vertical inserts directly within the walls 34 be arranged to provide additional reinforcement

10 illustrates a method for producing a packaging of the type shown in FIGS. 1 and 2. This method can also be modified accordingly in order to produce the packaging shown in the other figures. Fig. 10 shows the package during manufacture. The packaging begins with the flat pre-folded container blank 10. The fold lines. are at 101, 102, I03, 104 ₅ I05 and * IO6. The container is first bent over at a right angle along the fold lines 102 and I05. The package 1P is placed in the middle of the blank, whereupon the package 17 is placed with its side surfaces so that its top coincides with the folding lines 102 or

By bending it again of the blank at the fold lines 1C (5 and 104 are the Goods to be packaged 17 brought into an upright division so that the container 10 and the goods to be packaged 17 and 18 assume the position shown in FIG. As soon as the container, in · the in the · Fi.5. 1 folded shape is, the film can be wrapped around the package so that the ends of the same as in Fig. 9 shown overhang on both sides or an additional reinforcement insert with a misshapen cross-section can be placed over the Item to be packaged 18 are everted before the packaging is wrapped in the film, so that in this case those in Flg. 2 packaging is received. The packaging can be wrapped with the shrink film or the packaging can be pushed into a pre-formed film tube. The ralt of the foil wrapped The packaging is then sent into a shrink tunnel, in which the ends of the film are initially firmly pressed against the front sides of the packaging are shrunk, whereupon the remaining film, as in the above-mentioned US A = -Pate nt described, against the container and the packaged goods » is shrinking. If the shrink film has been sealed so that it completely covers the container and the packaged goods then it is not necessary to gradually shrink the film. Leaving the two open Ends has the advantage that the sealing of the film at these ends and cutting off the protruding Foil is not required.
