The present invention relates to a packaging unit comprising a bottle carrier and at least two bottles according to the preamble of the patent claims 1, 9, 13, 16, and 20.
For transporting bottles, in particular beverage bottles, various packaging units have become customary in the past. For example, on the one hand, a packaging unit is typical, which comprises beverage bottles, which are received in a rigid bottle case. In order to improve handling, bottle cases are also used, which are provided divisible, so that the packaging unit can be divided in two components of equal size and can be carried with both hands. Also known are packaging units made of a few bottles, e.g. six to ten bottles, which are received hanging in a bottle carrier, which is formed from a carrier body and a carrier handle, disposed thereon. By means of this packaging unit suggested in WO 2004/076310, in which the bottles are disposed hanging in the carrier body in the portion of their necks, all bottles can be lifted simultaneously by means of the carrier bar and transported.
An improved packaging unit is described in DE 20 2005 016 091, in which the bottle carrier comprises a carrier bar, which is integrally connected to the carrier body by film hinge connections in a manner, so it can be folded out and folded back in. Thus, simple and comfortable handling and a good and stable stacking of several packaging units is facilitated. In particular such a packaging unit can be manufactured cost effectively in spite of its stable and robust construction, wherein a bottle carrier made of polyethylene, in particular a polyethylene regenerate, is economically advantageous in particular.
Though this known packaging unit has considerable economic advantages, compared to known packaging units, there are applications, where it cannot be used in an optimum manner yet.
Thus, in the above designated packaging unit, the bottles are received in the bottle carrier, so they are safe against unintentional removal, however, the bottles can be deflected along their longitudinal axis thus from the vertical, so that when stacking several packaging units on top of each other, an unintentional release of bottles from the bottle carrier is possible by deflecting particular bottles from the vertical and lever effects are caused by the force acting upon them due to the stacked packaging units, wherein said lever forces cause leveraging this bottle out of the receiver and the bottle carrier.
Furthermore, the PET beverage bottles are typically closed by a screw cap and comprise a circumferential ring as a quality seal, which at least partially disengages from the screw cap after the first opening, thus documenting the opening process in a unique manner. Different from the crown caps, which can be opened by an upward lever effect, such screw caps can only be opened by a rotating movement of the cap relative to the bottle. This movement, however, can be made more difficult through multiple influences, so that under certain conditions, opening the bottle is not possible for the user, or not possible in a simple manner. For example, opening the screw cap becomes more difficult, when the hand gripping the cap, or the cap itself are not completely dry, or when the user is not capable to impart a sufficiently large torque onto the screw cap.
Last not least, it is not possible so far with the packaging unit described above, to assure that a voluntary or also involuntary removal of single bottles and the subsequent refilling of the packaging unit with single bottles is indicated to the user, so that so far no quality guarantee with respect to the contents of the packaging unit can be given to the user.
In a first embodiment, it is the object of the present invention to provide a packaging unit by which a safe stacking of particular packaging units is facilitated. In another aspect of the present invention, it is the object to provide a packaging unit, which enables the user to disengage the screw caps of the bottles directly within the packaging unit, wherein the packaging unit can still be manufactured in a simple and cost effective manner. Eventually, it is the object of the present invention according to a last embodiment to provide a packaging unit, which indicates the removal of single bottles of a packaging unit in a unique manner.
These objects are accomplished by the packaging units according to the claims 1, 7, 11, 14, and 18. The dependent claims respectively provide advantageous embodiments of these objects.
By means of the packaging unit according to the first aspect of the invention, the received bottles are prevented from being deflected from the packaging unit along their longitudinal axes. Thereby, it is assured that also in case of a vertical loading of the packaging unit, particular bottles are not disengaged from the packaging unit by lever effects, but only through purposeful manipulation by the user of the packaging unit. For this packaging unit according to the invention, three alternative embodiments are provided, each of which performs its function independently, but can also be combined amongst each other.
In a first embodiment of the first aspect of the invention, the packaging unit comprises at least one banderole, which is disposed substantially perpendicular to the longitudinal axes of the bottles and comprises all bottles together. By means of this banderole, a deflection of particular bottles from the packaging unit is effectively avoided. Thus, only the disposition of the bottles in the bottle carrier eventually allows an envelopment of the bottles by the banderole, since by the use of a banderole alone, the bottles would always align into a point symmetric manner, and thus e.g. an arrangement of six bottles in two rows with three bottles each could not be realized. The bottle carrier and the banderole thus form two mounting points, which are disposed remote from each other, for each bottle, so that no bottle can be deflected relative to the longitudinal axis of the bottle towards the outside out of the packaging unit.
Advantageously, the banderole envelops the bottles with a preload, so that the bottles cannot not only be deflected to the outside, but also not to the inside into the packaging unit. By means of this preload, furthermore, a pressure is built up within the bottles. Thus also bottles made from plastic, which typically comprise a very thin material thickness and thus little stability of their own, can also be stacked without problems in such packaging units, when the liquid received in the bottles is provided without gas, in particular without carbonic acid. Bottles filled with such liquids by themselves can be deformed in all directions. Therefore a direct stacking is not possible for static reasons. Such bottles thus had to be provided with stable surrounding packaging material, e.g. bottle cases or cardboard. By means of the banderole, which contacts under preload, thus thin walled bottles with a gas free liquid are deformed, so that a further deformation by means of vertical forces is substantially impossible. By means of the preload of the banderole thus a vertical stabilization of the particular bottles is performed, so that the packaging unit also obtains sufficient static stability in case of gas free liquids and bottles with very thin walls, whereby stacking a plurality of packaging units on top of each other is facilitated in a simple manner.
In case the bottles within the packaging unit do not directly contact each other, thus when they would be deflected by the banderole from the vertical towards the inside into the packaging unit, an intermediary layer can be disposed between the bottles in an advantageous manner, which is preferably made of cardboard or plastic, in particular made of a foam material. By means of this intermediary layer which is preferably disposed at the level of the banderole between the bottles, a deflection of the bottles towards the inside into the packaging unit is effectively avoided.
By means of such an intermediary layer, also an effective damping of the bottles can be provided, so that in case of glass bottles, no fracture can occur due to collisions of the bottles.
In an advantageous manner, the banderole is provided as an enveloping plastic band, in particular made of polypropylene, polyethylene, or polyethylene regenerate, wherein the lateral ends of the enveloping band are preferably fixated to each other, in particular welded or glued. Thereby, a particularly simple and cost effective manufacture of the packaging unit is facilitated, in particular also when the banderole envelops the bottles with a preload.
Thus, the banderole is preferably provided as an advertising medium and covers in particular a substantial portion of the cylindrical body of each bottle. Furthermore, it is advantageous, when the banderole is disposed in the lower third of the bottles, in particular in the portion of the bottoms of the bottles, since then due to the leverage effect a deflection of bottles is avoided most efficiently.
In a preferred embodiment, the bottles comprise a stop surface, or an enveloping surface around their circumference, in particular in the form of a recess or shoulder, wherein the banderole is then e.g. received in the recess, or contacts at the shoulder. By this measure, the position of the banderole around the bottles is exactly predetermined and fixated, so that the position of the banderole does not change, also while transporting the packaging units.
According to the second alternative of the first aspect of the packaging unit according to the invention, a tray is provided, which comprises a receiver for the bottoms of the bottles, wherein the receiver comprises contact surfaces above the bottoms of the bottles, and the contact surfaces surround all bottles on the outside at least with reference to the packaging unit and thus at least partially around the circumference of each bottle. It is assured also by this that the bottles cannot be deflected along their longitudinal axes out of the vertical and out of the packaging unit.
Preferably, thus the contact surfaces are provided, so that the bottles are directly enveloped, in particular under a preload, thus the contact surfaces contact the bottles. In a particularly preferred manner, the contact surfaces are provided so that each particular bottle is at least partially enveloped, so that it is substantially fixated against lateral deflection on the tray. Thus, the bottles are secured relative to a deflection from the packaging unit and also from a deflection into the packaging unit, so that no larger lever forces can be transferred to the connection between bottle and bottle carrier and thus no bottles can be disengaged from the packaging unit. In a particularly preferred manner, the tray comprises at least one recess at its bottom side, which is formed corresponding to the upper shape of the packaging unit, thus corresponding to the bottle carrier and to the bottles received therein. Thereby, packaging units formed by trays not only can be stacked on top of each other, but the particular packaging units can be positioned relative to each other in a particularly simple manner.
According to a third alternative of the first aspect of the present invention, the bottle carrier comprises contact surfaces, which envelop all bottlenecks of the received bottles externally at least with reference to the packaging unit and thus at least partially around the circumference of each bottleneck. Thereby, at least a deflection of the bottles from the vertical and out of the packaging unit is avoided. Preferably, the contact surfaces directly contact the bottlenecks in particular under a preload.
In a particularly preferred manner, the contact surfaces are provided as collars, which extend downward from the receivers of the bottle carriers, with reference to the carrier bar and which envelop the bottlenecks at least partially.
According to another aspect of the invention, which can be used by itself, or in combination with the above described alternative embodiments, at least between the bottle carrier and a cap of a bottle received therein, coupling elements are provided, which are configured, so that they correspond to each other, so that at least against the opening direction of the cap, a contact between the coupling elements can be formed. By means of this embodiment, the cap of a bottle can be provided within the packaging unit in a simple and convenient manner, so that the bottle to be opened is rotated against the opening direction of the cap within the packaging unit, wherein due to the stop between the coupling element of the cap and the coupling element of the bottle carrier, the cap is exposed to a torque in its opening direction and is opened thereby. Due to the fact that the user does not have to rotate the cap relative to the bottle anymore, but rotates the bottle relative to the packaging unit, a large torque can be transferred to the cap in a particularly comfortable manner, so that the cap can be disengaged from the bottle in a much simpler manner, than before.
In a preferred embodiment, the bottle carrier comprises bars integrally formed at the carrier body, which extend vertically upward from the upper side of the carrier body, and the screw caps each comprise a collar shaped protrusion. In an advantageous manner, the bars are directly disposed at the clip shaped receivers of the bottle carrier. In order to assure free rotation of the bottle relative to the bottle carrier, a sliding ramp can be provided at one of the coupling elements, which allows the corresponding coupling elements of the bottle carrier and of the cap to slide pat one another in the opening direction of the screw cap. In this manner, a particularly simple azimuth positioning of the bottle within the bottle carrier is possible, so that the label of the bottle is positioned relative to the bottle carrier in a manner that facilitates advertising. When the position of the print, or of the label of the bottle can be adjusted relative to the coupling element of the cap of the bottle in the production process, it can however also be provided that the coupling elements are part of a spline connection, and stops are provided in opening direction and also against the opening direction of the cap, which prevent a rotation of the bottle relative to the bottle carrier without opening the cap.
The banderole and also the tray and the contact surfaces of the carrier bodies for the bottlenecks form a rotation hindrance for the bottles relative to the bottle carrier. Thus, a rotation of the bottles and thus of the labels and imprints of the bottle, which are aligned for advertising efficiency, is substantially hindered, so that the packaging unit always presents itself to the viewer in its intended configuration. In particular by means of the banderole wrapped around the bottles with a preload, but also by contact surfaces of the tray, or of the bottle carrier contacting the bottles under a preload, unintended accidental rotation of the bottles relative to the bottle carrier can be avoided even more efficiently.
According to a third embodiment of the present invention, a packaging unit is provided, comprised of a bottle carrier and bottles, wherein each bottle receiver of the bottle carrier is provided with a seal, which indicates the removal of the associated bottle from the packaging unit. By means of this seal, a quality assurance of the packaging unit is assured by indicating to the user in a unique manner, when a bottle, which was initially included in the packaging unit, was removed or exchanged.
In a particularly preferred manner, the seal is then formed in the clip shaped receivers of the bottle carrier by two protrusions, each of which reaches into the bottle receiver at the end of each clip. The material of the protrusions, or their geometric shape is thus determined, so that they break, or irreversibly deform, when the bottle, which is initially inserted into the receiver, is removed.
In an advantageous manner, the banderole, the tray, and the bottle receiver of the packaging unit comprise an identifier in the form of an optical code, in particular a bar or color code, or an electronic code, in particular provided as a transponder. Thereby, storage, transportation and sale of the packaging unit can be optimized.
Further advantages, characteristics and particular features of the present invention are subsequently described with reference to the appended drawing, showing in:
For receiving and fixating the banderole 4 at the bottles 3, they comprise a recess 10, into which the banderole 4 engages along part of the circumference of each bottle 3 and is thus fixated in its position. The banderole 4 is comprised of a polypropylene strip and disposed around the bottles under a preload, wherein the ends of the strip are welded or glued together. By means of the preload, the bottles 3 are pressed against each other and simultaneously in case of liquids without carbonic acid being included in the bottles 3, a pressure is imparted onto the bottles 3, which stabilizes the bodies of the bottles. Due to the fixation of the bottles 3 on both sides of the bottle carrier 2 and the banderole 4, the packaging unit 1 is stabilized, so that also in case of a stacking of several packaging units 1, the bottles 3 cannot pivot out of the packaging unit 1, so that lever forces act upon the receivers 7 of the bottles 3. Thereby it is assured, that the bottles cannot leave the packaging unit 1 in a simple manner.
