Description

Wrapping for packages with extraction aid, in particular for cigarette packages.

The invention relates to a wrapper for packages, in particular to a package wrapper cigarettes The package wrap may be a packaging but also a dispenser or dispenser for such packages. In the This description describes the technique according to the invention by means of of a wrapper for packages for tobacco items, being indicate that this technique is also realizable without further ado packages for other items are collected forming a envelope.

Tobacco items are sold in the form of packages but also in wrappers (as "cartons"). Sometimes wraps with 10 packages are offered, which directly they are located next to each other, that is, in a row, but wrappers with two rows of packages are also known, in the which in each are stacked next to each other five (or more) packages.

It is always problematic in such wraps the extraction of individual packages, because the packages or are difficult to grab or wrap container (in cigarettes frequently of paper or cardboard) must be destroyed, to reach the individual packages.

In GB 2 341 174 A and in the US 6,062,424 outer packages for packages are described individual, which have separable extraction openings. For wraps with several stacks, in which a package of one stacking makes it difficult to remove the package from the other stacking located next to it, however, there is no solution principle satisfactory.

A package wrap according to the preamble of claim 1 is known from the document US-A-2 546 986.

The problem of the present invention is to facilitate or make it easy to extract packages Individuals of a package wrap with at least two packet stacks located next to each other. This problem is solved by a package wrap according to the claim 1. The dependent claims define forms Preferred embodiments of the invention.

The package wrap according to the invention it comprises at least two stacks of packages located one at side by side, particularly cigarette packs, as well as a outer packaging that encloses the stacks, being provided or being feasible in the area of a front side of the envelope a extraction opening. On the front side with the opening of extraction is provided a retention device between two stacking, which acts alternately movable on one or another stack, in particular located next to it, and thereby prevents the advancement of their packages in the area of the opening of extraction.

In other words, the present invention comprises a package wrap that has a type of mechanism pendular which is arranged between two stacks of packages and prevents subsequent sliding of a row of packages, from so that the first or lower package of the other row of packages It can be easily extracted. A package wrap similar according to the invention or an analogous mechanism is appropriate both  for disposable outer packaging (paper or cardboard) as for dispensers or dispensers, which may be installed as refillable means of sale.

The retention device can be by principle a hand-held or hand-operated retention device,  but it is explained below by means of embodiments preferred that present an automatism that makes in each case alternatively a packet of a stack is extracted and then of other. Individual packages are easy to grab on the extraction opening, so that the extraction can be carried out simply and without difficulties as well as without a destruction of the envelope.

In an embodiment of the invention the retention device is retained by a package of a stacking in a situation where it prevents a package from stacking or other stacking advance to the opening area Extraction A package therefore retains the device from retention so that the latter blocks another's package stacking

In addition, the invention can be carried out so that the retention device is arranged movable or tilting so that by means of a stacking package, which advances to the area of the extraction opening, is transferred to a situation in the one that prevents a package of the other stack from advancing to the extraction opening area. In other words, the sliding a packet from a stack leads to the retention device automatically move to a position in the which blocks the packet from the other stack next to it. This naturally it can be done in turn or alternatively, of so that a packet is always alternately extracted from a stacking and the other stacking is blocked. The device of retention or retention function "oscillates" thus between stacking

There is the possibility to configure the envelope for packages according to the invention so that the device of retention at the extraction end of the envelope can rotate on a point between two stacks on an axis of rotation. The axis of rotation is located in particular essentially higher at a height of package that the bottom surface of the package in the opening of extraction.

The retention device may have two butt sides that are at an angle, particularly at right angles with each other, in which the package that is located in the area of the extraction opening and the package that is prevented in advance in the extraction opening. On one side of bumper is therefore supported the package that is located in the area of the extraction opening, and in the other the package that is prevented in advance to the area of the extraction opening.

The retention device may present the body shape with the cross-sectional shape of a right triangle and / or isosceles, in which the butt sides concur in the axis of rotation of the retention device.

In a variant embodiment of the envelope for packages according to the invention, between two stacks located one next to each other, on whose packages the element of retention, a guide or separation wall is arranged. The separation wall can prevent packages from moving they are caught reciprocally on the extraction opening. This wall does not have to be configured as a continuous wall; is enough to separate the path of travel from one another sliding of packages so that they can be transported without impediment.

In special configuration in a variant similarly the retention device is arranged or attached in the edge of the extraction side of the separation wall, in particular with its axis of rotation. It is also advantageous that the retention device does not extend over the total length of the package, in particular that is lowered in the area on the side of extraction of the extraction opening.

There is the possibility of wrapping from a folding cutout of paper or cardboard material, the extraction opening being formed in particular by means of a separable material section. On the other hand it is possible to do the wrap of a rigid material shaped to the shape of the wrap, especially of a plastic material, a material of glass or a metallic material. In such a case the envelope for packages according to the invention it serves as a dispenser or dispenser, for example as advertising support for sales purposes.

The retention device may form a integral component of the wrapper or cutout, in particular a folding cutout flap. The same is true for the wall of separation; it can also be prepared as an integral component of the wrapper or cutout, and if a paper material or carton, as folding folding flap.

Another configuration variant is that the axis of rotation of the retention device is formed by a flapper film or a folding edge of the cutout. It is important that the retention device can rotate freely; whatever configured the axis of rotation depends on the material. In case of plastic materials could be proposed a film hinge, while in the case of paper or cardboard materials you can choose a folding edge

The invention is explained in detail to continuation with the help of an embodiment and doing Reference to the attached drawings. The invention can comprise all the particularities described here individually as well as in Any convenient combination. In the drawings they show:

Figure 1 a schematic representation of the separation or retention mechanism for a wrapper for packages according to the present invention;

Figure 2 the arrangement shown in Figure 1 after the extraction of a package and the change of site of the retention device; Y

Figure 3 a cutout for the cardboard version or wrapping paper.

Figures 1 and 2 show the basic mechanism of the present invention. Figure 1 represents an initial state; the Figure 2 the state after the extraction of a package.

The packaging of the envelope is not represented in Figures 1 and 2; for the basic mechanism that is just important as long as the parts of the mechanism can also be parts of the wrapping packaging. Corresponding settings They are described later in detail.

For the description of the mechanism of distribution of packages according to the invention it is represented that in the Figures 1 and 2 show a vertical system from the front, which presents a stack of packages left 1 as well as a stack of right packages 3, each of five packages, of which one as an example it is provided with the reference sign 5. The packages they can be for example cigarette packs, which with a Small front surface are directed towards the observer. He lower pack of the right stacking 3 is in the extraction position, that is, with a wrap in position where the extraction opening is located. The opening of extraction not shown here extends approximately over the height of the pack of cigarettes 7 and in width over width total of the two stacks 1 and 3. The two stacks are separated by a central guide element, here the wall of separation 9, which prevents packages from moving laterally and get hooked reciprocally. Packages can so both "pass through" down.

On the lower side, so to speak among the stacks 1 and 3 a retaining element 11 is found here Triangular configured. Element 11 does not extend over the total length of packages that penetrates the drawing plane, but it leaves remaining at least on the front side (visible side in Figures 1 and 2) site somewhat lowered, so that the packages in the extraction position even from the center can be grabbed well. Furthermore, it can be achieved that element 11 already can rotate before the package is fully removed, to thus retain the stack placed on it.

The retaining element 11 can rotate around its contact line with the separation wall 9 (in the plane of the blade), and the corresponding axis of rotation is indicated with the reference sign 13. Said axis of rotation in the position represented from the packages is approximately one package height above the bottom surface of package 7, which It is located in the extraction position. If the axis of rotation was located higher than a package height, the edge bottom of the second unblocked stacking package would be located lower and thus a dejection of the element 11 after removing the package in the extraction position.

The triangular retaining element 11 in the represented embodiment has a rectangular shape, isosceles, the right angle being located on the axis of rotation 13. A surface 51, which starts at the right angle, is contiguous perpendicular to the inner side of package 7; the other surface 55 supports horizontal to package 8. It is also conceivable to give the retaining element 11 another form, for example as a pendulum with a cylinder or a sphere at the lower end of the wall of separation 9.

In Figure 1 the retaining element 11 is turned to the left and keeps the left stack 1 in an elevated position, essentially higher in a package than the extraction position. Package 8 therefore cannot be extracted, and the space under package 8 is free for the grab by a user. By package 7 in the position of extraction in the right stack 3, which fixes the element of retention 11 in the situation of Figure 1, prevents the retaining element 11 can rotate clockwise.

If package 7 is now removed, the item from retention 11 turns clockwise by the mechanical pressure of the stacking 1 (pressure by weight), and stacking 1 can fall down. Thus the package 8 of the left stack 1 now reaches the extraction position, and the right stacking 3 It is held in the highest position. This status is shown in Figure 2. The package can then be removed 8, the stack 3 presses the retaining element 11 towards the left and the package 10 reaches the extraction position. This can be continued until both stacks are finished

The principle according to the invention can be realized in one embodiment by means of a cutout for a cardboard of wrap, like the one shown in Figure 3. The lines thin here represent fold lines, thick lines are outer edges / sections, dashed lines perforations.

Wrapping cardboard is made up of following main surfaces: a front wall 15 and two side walls 17 and 19, to which parts 21 and 23 of the rear wall When folding these surfaces forming a cube the parts 21 and 23 of the back wall overlap, so that they can stick, in particular by overlapping surfaces 23 on 21. On the part 21 of the back wall is the flap of separation wall 25 in which a strip of fixing 27, which sticks with the front wall 15. After pasting these parts therefore results in a cross section with two spaces gaps, which can accommodate packages in the form of parallelepiped.

On the upper side of the cutout you can see the cover element 29 with the insertion tab 35 as well as the two upper side flaps 31 and 33. In the folded state the wrap is thus closed up.

On the bottom side is the element of bottom 37 with side flaps 39 and 41 as well as tabs of introduction 43 and 45. When folding the side flaps 39 on the fold lines drawn result in a mechanically bottom stable that on the inner side of the wrap is smooth, so that packages are supported flat and can be easily removed. The lower side flaps 39 and 41 are found after folding corresponding to the outer side of the envelope. To extract folded wrap package packages, the perforation on the opening flap 47 and the trapdoor The punched semicircular punches 47a, 47b They serve for ease of grip from the side (from outside). So packages can be caught in the wrapper. Punching Semicircular die cuts are provided for the easiest folding from the bottom of the wrap.

On the separation wall flap 25 (it becomes the separation wall 9 of Figures 1, 2) the flap 49 is placed, of which a triangular element can be formed by folding (as in Figure 1). The individual elements below the separation wall flap 25 result (from top to bottom) one side 51 of the isosceles triangle, the bottom part 53 of the isosceles triangle, the other side 55 of the isosceles triangle and the introduction flap 57 This introduction flap 57 is inserted through the two punched punches 59 and 61 of the flap 49, and thus a mechanically stable element is formed, which can take over the function of the retaining element 11 of the Figures.
1 and 2.

The flap 49 can be folded finished in the Wrapping package manufacturing and filling with packages. So the consumer does not have to perform any other task to Find the mechanism willing to work. It is also conceivable, however, to leave the folding of this part to the consumer. This would be advantageous with respect to the filling of the envelope, since the unfolded flap does not need any additional site and therefore the complete envelope can be filled with packages.
