DE19926536A1 - Flat cardboard packaging - Google Patents

Abstract

The invention relates to a packaging unit that is produced from essentially flat cut-outs, consisting of a lid (1), a base part (3) with recesses (15), and segments (15) for subdividing the base part into compartments (14) for holding round or egg-shaped packaged goods. The invention also relates to a method for separating the packaging units and filling them with the packaged goods.

Description

The invention relates essentially to packaging made from flat cardboard blanks, best starting from a cover part, a bottom part with recess Stanchions and webs for dividing the bottom part into Acquisition cells for the acquisition of round or egg-shaped Packaged goods.

Conventional packaging for eggs usually consist of Casting cardboard or plastic, which with a defined shape be produced and as stacked units, be consisting of a large number of identical packaging be delivered.

This type of packaging has the disadvantage that it Comparatively bulky even when stacked and therefore due to the poor volume filling, causes considerable transport costs.

Furthermore, the packaging has surfaces that either not or because of their porous rough Surface only with poor and less appealing Have quality printed immediately. So that's it Applying printed labels to the consumer formation has become common. Applying these eti chain is due to the price of the label and the additional adhesive step required, but from Not very advantageous for reasons of cost.

Another disadvantage of packaging made of cast cardboard is the - compared to corrugated cardboard - unfavorable mate  rial price and the high sensitivity of the cast cardboard against moisture. Influences air humidity for example, the surface area of the mate rials than is the case for corrugated cardboard. constant Dimensions of the packaging units are important for the machinability. Most eggs though packaging machines to relatively high tolerances leave, too large fluctuations lead to errors in the operational process.

Every year in the Federal Republic of Germany produced more than 100 million egg packages and sold. Even slight differences in the manufacturer Price per package including printing guarantee in view of the Quantity of a sale that should not be underestimated advantage.

Since six in the Federal Republic of Germany or ten-packs made of cast cardboard for "quasi- Standard "for egg packaging has developed important for new packaging to be developed, that this without modification of the conventional Eierver packing machines must be used for these machines.

WO 96/38355 describes a packaging for eggs knows that from a made of cast cardboard Un Part for holding the eggs and one made of cardboard paper pe existing top part, which z. B. about Adhesive strips hinged to the lower part is. The cover made of cardboard is printable.  

From DE 32 33 511-A1, WO 98/43897 and US 4,934,533 packaging is known. The flatter Corrugated cardboard can be produced by folding and gluing. However, these are not stacked when open bar and therefore in conventional packaging machines not usable. Especially the packaging according to US 4,934,533 have in the closed state also an inadequate stability on the one Safe stacking of filled packs prevented.

The object of the invention is that described above Overcome disadvantages of the prior art and inexpensive and machine-compatible packaging to provide. For machine packaging it is necessary for these to be stacked, which ver packing machines as stock on the entrance side serve, let layer and then ver machine leave alone.

This object is achieved according to the invention by packaging comprising a cover part and a base part, the base part

• - One or more ridges projecting upwards towards the Un division of the bottom part into receiving cells points and
• - Recesses in the accommodation of the web (s) of an un like the stacked open carton second opened cartons,

and lid and bottom surface made of flat cardboard are made. Preferred embodiments are reproduced in the subclaims.  

As a rule, the packaging has several webs, created by dividing the packaging so that several rows of recording cells be formed.

According to a further embodiment of the invention the receiving cells designed so that they are on serve spherical or egg-shaped objects. Here for the webs are preferably designed so that this is from the bottom part upwards in the surface, preferably circular or arcuate, at least ent taper along a section. After another preferred embodiment, the cardboard area expands surface of the bridge as soon as the bridge reaches the con clocks with its largest areas in the middle expansion - based on a parallel to the floor slab le cut surface - having round or egg-shaped packaging packaging located in the receiving cell object loses.

According to a further embodiment of the invention the web has upper, lateral and / or lower retaining tabs on by incisions and possibly by folding the the web surfaces forming webs can be formed and are articulated to them. This Haltela at least under pressure or force with the counter located in the receiving cells have points of contact and others Give in springy pressure.  

The webs preferably protrude from the base part to the bottom of the lid surface. This will a good one for stacking the filled packaging Stability created. Here, the must be different from the inner floor surface extending webs not necessary maneuverably in one piece up to the cover plate but can be closed also with webs on the cover plate con tact all the more - in addition to the side walls Connection between inner lid surface and bottom surface che form.

It is also possible that the packaging items through one or more into the receiving cells, d. H. e.g. B. between the web and the side wall, placed or possibly additionally glued, soft yielding packaging materials such as crepe paper or foamed Plastic film to be protected.

The side walls are preferably two or more parts lig formed, the side parts by cut edges and / or folded edges are separated from each other. The packaging preferably has - in relation to one Side wall - a lower and an upper side part on. According to a further embodiment, the separation line between the upper and lower side part longer than the edge, the side part and bottom surface or sides part and lid surface forms. Furthermore, the top and the lower side part of a side wall essentially equal heights.  

From the angled side walls preferably has at least one tab each on the side wall in the erected state the angled against this other side wall, preferably by gluing. The tabs are preferably triangular and have the Side part with which they are connected at an angle, one Folding edge.

Lid and bottom part are, preferably by a Fold edge in one of the side walls, gel together kig connected. Furthermore, the opposite other side wall one or more devices for Close the lid.

The devices for closing the lid are in front preferably designed so that this one off Bookings and on the other hand have recesses that serve to accommodate the bulges. One of the two Parts of this holding device is on one or more in the closed state of the packaging under the Side wall of the lower part or the cover gripping Locking tab attached.

The floor area has recesses for receiving of the web (s) one under the opened packaging stacked like second packaging. The Recesses can ver in the longitudinal or transverse direction run depending on the shape of the webs. Preferably they have Cutouts, however, have an approximately rectangular shape where with the longer leg of the recess parallel to shorter side wall is aligned. The remaining one  inner bottom surface provides the underside of the webs Stop. The webs are preferred on the floor surface attached by glue.

Suitable materials for the production of the flat card tone cut can be: single or multi-layer car clay materials, such as homogeneous cardboard, duplex cardboard or Triplex cardboard, cardboard with synthetic fiber or art fabric (composite), corrugated and coat cardboard materials. The printing can e.g. B. with book printing, offset printing or gravure printing.

Suitable packaging goods are fragile bulk goods ren such as B. eggs, shock-sensitive chocolate goods or fruits.

The packaging according to the invention can be opened state in the storage containers of Eierverpac machines can be stacked. These ever take because bottom carton from the stack, the Grei fen is usually done with puncture needles, turn and lead the opened box into a posi tion to take up the eggs. Then the box is ma closed quickly, it is important that the Locking tab under the closing lid engages to lock the bulges in the Allow lock holes. For this, the Locking tab slightly while closing the lid raised.

At the same time, the boxes of the invention Advantage on that this in the form of flat cardboard section  can be transported and only before use by a folding machine, possibly using glue fabric, be erected.

The packaging according to the invention also has have the advantage that they are printed on all sides can and through the recesses in the base plate checking the condition of the packaging goods arbor.

The cartons according to the invention have been tested in practice demonstrated that these are excellent, zer fragile goods against impact and pressure protect. This was e.g. B. tested in field trials, whereby egg packaging according to the invention several times over stacked up and several hundred kilometers in Automobiles were transported.

Advantageous embodiments of the invention are in the Drawings explained.
