Description

in DK 167111 B1

The invention relates to a container carrier of foldable sheet-shaped material, in particular for bottles, cans or similar containers.

Such a container carrier is e.g. known from German Patent No. 2,756,374. The superimposed ends of the format 5 are usually connected to each other in the bottom region, namely either by adhesive or by a suitable bonding. The bottles or cans, with their edges at the top and bottom, partially open into openings so that they are retained in their position and secured against dropouts. Particularly for cans or bottles which are cylindrical in the lower region, the lower transverse wall, which limits the openings at the corners, is relatively narrow. In terms of material load, this transverse wall is the weakest site in the container carrier. In addition, if it becomes damp, there is a danger that it will burst. As a result, the adjacent bottles are no longer secured. Furthermore, there is a danger that the container carrier will be torn down altogether. For this reason, it is necessary to give the format a minimum thickness for strength reasons.

It has already been attempted to reinforce the end regions in a special shaping of the format 20 so that the material weight of the format can be reduced. For this purpose, the peripheral area of the openings at the corners of the container carrier are formed by means of section lines such as flaps or lugs which are inwardly in contact with the associated container. However, the desired increase in strength is not very large. Above all, the disadvantage is that the remaining outer transverse wall becomes particularly narrow. If it is weakened by moisture in its tensile strength and torn over, any power transmission in this area lapses with the disadvantages listed above.

30 The container carriers are mechanically placed cuff-like on already standing container bundles. The folding of the peripheral regions described above at the openings at the last described container carrier requires an additional manufacturing step with additional machine parts. This packing machine therefore requires a greater cost of DK 167111 B1 2. A container carrier of this kind, in which flaps or lugs are connected to the outer cross walls via fold lines and are separated from the wall sections and the bottom sections by slots, can be obtained from EP-A-0 170 490.

Finally, EP-A-0 059 104 discloses a carrier which also has outer flaps for openings for a lower container edge flaps or tabs. These flaps or lugs are connected only to the outer transverse walls in the region of an inclined wall via connecting elements which are separated from each other by an expansion side and located near fold lines. As a result, outward forces are directed into the weakened regions of the outer transverse walls. In addition, there is no support function for the flaps or the lugs, which are only taken over by the outer transverse walls against the edge. Therefore, especially at the inclined wall, the support is extended and has a relatively high material weight.

The object of the invention is to provide a container carrier of the kind mentioned in the preamble which permits a noticeable reduction in the material weight of the format. Furthermore, the mechanical cost of placing the container carriers on the container bundle should not be increased.

In the container carrier according to the invention there is an additional cross piece which in the first line corner area takes over the power transmission from the wall section to the bottom section. It gets 25 not only a carrier function, but also a relief function for the outer transverse wall areas. In that the cross-wall section covers part of the opening, when laying the format around the container bundle in relation to the other format it is deformed so that it adheres more or less to the container wall.

30 Force point of attack one between the inner cross section and the bottom section or wall section is thus further displaced inwards, so that the danger of its tearing is reduced. Even when a tear or tear occurs, a separation of the cross piece from the wall or bottom part does not yet occur.

With a corner design according to the invention, a noticeable increase in the strength of the container carrier in the critical area can be achieved, so that the material weight can be reduced accordingly. A further mechanical device is not required. The container carrier according to the invention is placed in a known way in a vertical plane around a ready-made bundle. The inner cross section automatically occupies the desired position. If it is due to excessive forces or due to a corresponding weakening of the inner cross section for a tear, the outer cross section takes over before no one. Thereby a double fuse is obtained.

In known container carriers, a bending line is formed between the bottom section and the wall section. It facilitates the folding of the casing around the container bundle. In the embodiment of the container carrier according to the invention, in this connection it is assumed that a bending line extending in the outer cross-section relative to the bending lines between the bottom section and the wall sections is offset in the direction towards the wall sections. Such a bending line displacement allows the inner crosspiece to be slightly rotated without bending the bottom wall relative to the wall section, thereby constituting a restriction against a slide of the bottle or a similar object.

Since the inner cross section also partially engages the bottom of the container, according to a further feature of the invention, it is useful when a transverse bending line in the inner cross section is approximately equal to the bending line between the wall section and the bottom section. Preferably, this bend line is offset somewhat relative to the bend line between the wall and bottom sections in the direction towards the wall section.

The above-described deformation or oscillation of the inner cross-section is facilitated in a further embodiment according to the invention when the inner cross-section is hinged via an abdominal line extending in the wall section and / or in the bottom section. In the above-described deformation of the inner crosspiece, the buckling line not only serves to form a hinge, but the material in the region of the buckling line is compressed wedge-shaped, without thereby reducing the force transfer. The last described bending line in the wall section extends approximately parallel to the free side edge of the wall section. The corresponding bending line in the bottom section extends at an angle with the free side edge more specifically so that it increases towards the bottom section from the free side edge thereof 10. The inner sections of the inner cross sections extend according to a further embodiment of the invention. point to the ends of the bending lines between the inner and outer cross sections. They are at least at one end preferably arcuate curved. According to yet another embodiment of the invention, at least one incision extends beyond the end of the inner cross thick. It preferably extends from the bend line end further into an arc from the free side edge of the wall section or the bottom section. If there is a recovery in this area, the crack is guided into the full material in the wall section and the bottom section, so that the container carrier remains as sustainable as before.

A further critical area for a container carrier of the kind mentioned in the preamble is the gripping region or region, respectively, of the openings through which the capsules or upper edge of a can or similar container appear. Here it can also tear up the material, especially when the format is only a small thickness. The risk of tearing can be increased by the fact that a container is somewhat higher than the normal height. Thereby, the material in the orifice area is substantially loaded and can be torn. Therefore, a design according to the invention ensures that the openings at the transition from the lid section to the wall section have a width equal to or greater than the diameter of the capsule, and the distance from the bend line in the lid section is greater than the distance between the center axes of two adjacent sides. lying bottles. The bending lines in the lid section are arranged so as to be spaced apart from each other, that a free space is created between the bottles and the carton format. With this clearance, tolerances in the bottle height can be compensated.

A further critical area is the upper edges of a container carrier. Therefore, a further embodiment of the invention ensures that the bending lines in the lid section between the outer apertures and the side edges of the wearer converge towards the side edges.

The obliquely arranged outer bending lines at their position effect a stabilization of the outer format region by pressure exertion 10 from above such as e.g. can be done by shrinking the container carrier.

Finally, further loading of the container carrier occurs as the upper wall sections are progressively pressing against the bottles and the bottles in turn are pushed apart in a direction towards the wall sections. Consequently, it may tear up the upper openings. In order to avoid this danger as well, a design according to the invention ensures that the middle openings for the bottleneck on both sides of a notch extending perpendicularly into the orifice have two inclined downwardly converging notches ending before the openings . These incisions allow the bottles placed (in the middle of a six-bottle pack) by lifting the bundle outwardly pressing shear forces, which would otherwise wear out the middle openings by a rigid holder of the format, are diverted downwards past the openings as tensile forces.

The invention will now be described in more detail with reference to the drawing, in which 1 is a plan view of a container carrier according to the invention; FIG. 2 is a perspective view of the raised format of FIG. 1 with recorded bottles, DK 167111 B1 6 fig. 3 is a perspective view of the bundle of FIG. 2 is an oblique view from below, and FIG. 4 is a corner region of the format of FIG. First

The format of FIG. 1 is predominantly traditionally designed. It has bottom sections 10, 11, wall sections 12a, 12b, 13a, 13b and a lid section 14. Wall sections 12a, 12b are interconnected via a bend line 15 and wall sections 13a, 13b via a bend line 16 shown punctured).

In the transition area between the wall sections 12b and 13b and the lid section 14, six openings 17 are formed. In the transition area between the bottom section 10 and the wall section 12a three openings 18 are formed. In the transition area between the bottom section 11 and the wall section 13a, three openings 19 are formed. The shape of the apertures 17, 18 and 19 are not discussed further except for the apertures 18 and 19, respectively, in the corner regions.

15 For this, the detail 20 in FIG. 1 shown on an enlarged scale in FIG. 4. This will be discussed in more detail below.

The apertures 17 are as shown in FIG. 1, crescent shaped and extends extensively in the wall sections 12b 20 and 13b, respectively. With the ends, the apertures 17 extend beyond the bending lines 50, 51 and somewhat into the lid section 14. The width or diameter of the apertures 17 is selected to be somewhat larger than the diameter of the capsules of bottles received by the container carrier. The distance between the bending lines 25 50, 51 is chosen to be somewhat larger than the axis distance between two adjacent bottles. In FIG. 1, it is further apparent that the bending lines 50, 51 at both side edges of the format extend obliquely outwards and towards each other as shown at 52.

30 Into the apertures 17 extend a notch 53 which extends approximately parallel to the side edges of the format. At the middle openings 17, on both sides of the incision 53, two additional incisions 54, 55 are formed, which extend diverging in the direction towards the opening 17 and terminate in front of the opening 17.

The FIG. 1 is placed around a ready-made bundle, e.g. a group of six bottles 21 with narrowed 5 necks. It is recognized that the necks of the capsules are partially visible through the upper openings 17. Similarly, the edges of the bottom of the bottles 21 appear beyond the lower openings made by the openings 19. The bottom sections 10, 11 are suitably connected to each other. This will not be discussed in more detail. The format is thus laid cuff-like around the bottle bundle, and the bottles 21 are secured against falling out by the engagement in the openings 17, 18 and 19. The location of the bending lines 50, 51 allows for the tolerance of the bottle height to be compensated. Between the bottles and the carton format, a free space is formed by the bending lines 50, 51. Therefore, since the capsules can move more or less freely through the openings 17, the danger of tearing the format is avoided, even with larger bottles. The oblique position of the bend line 52 provides a stabilization against a pressure effect from above. The incisors 54, 55 allow the two bottles placed in the middle to lift the bundle outwardly to the sides. Shear forces, which would otherwise wear out the middle apertures 17 by a stiffer holder of the format, are diverted downwards past the apertures 17 as tensile forces. As can be seen in FIG. 1, the 25 middle apertures 18 and 19 are respectively symmetrical with respect to the longitudinal axis of the format and are in the flat state as a symmetrical crank. By means of a semicircular cut line 22 a tongue is formed which extends into the middle region of the openings 19. The tongues 23 30 thus formed lie, as can be seen in FIG. 2, against the bottle wall. The projection 24 protruding against the tongue 23 in the opening 19 abuts the bottle bottom.

In FIG. 4, section 20 is shown relating to a corner of a container carrier.

Claims (13)

11. A perpendicularly extending bending line 41c lies at the end of the recess 56 and deeper than the bending line 39c, however slightly higher than the bending line 40c between the wall section 13 and the bottom section 11. The opposite side edge of the inner cross section 26c extends obliquely. upward and outward, whereby in the upper region indicated by the incision 28c it is of an outward bend. Thereby a kind of hinge is formed without any material weakening, e.g. with a bow line. In the lower region, ie. in the region of the bottom section, the inner transverse piece 26c is triangularly shaped, its edge 58 extending obliquely outwardly towards the bend line 57. The edge 58 is formed by a section 59 of the opening 19c. The mode of operation of the embodiment shown in FIG. 4 is as follows. In laying the format around a container group, the inner cross piece 26c rotates somewhat and lays more or less against the bottle wall. Accordingly, the described corner structure has a much greater strength than conventional container carriers. Therefore, a material saving of 20% or more can be achieved. Incidentally, by turning transversely thick 26c against the bottle wall, a fuse is obtained against an extension of the lower region of the bottle by the container carrier.
