Description

The combined package

and method for producing a combination package

The invention relates to a combination packaging according to claim 1 and to a method for producing combination packaging according to claims 13 and 14.

There are known yogurt combination packaging consisting of a sealed by a foil twin cups containing two different, to be mixed during consumption food. For drinks and other foods such twin cups are only conditionally applicable, especially not when a food is carbonated or is under pressure.

From DE 41 18 090 A, a combination packaging for liquid or liquid-like food is known, which is designed as a tin can, whose tear tab having a lid on the underside bounded a second chamber in the can interior. By manipulating the tear-open tab, each chamber can optionally be opened.

From DE 20 2004 010 515 U a combination packaging is known, which consists of two juxtaposed with their longitudinal sides, approximately the same height, bottle-like plastic containers, which are held by at least one label separable from each other and each have their own upper closure.

DE 199 50 884 A discloses a combination packaging for two different cosmetic products to be mixed for consumption, which consists of a lower, bottle-like container with an external thread in the upper mouth region and a plug inserted into the mouth region after filling, and a second container , which is open on the underside and has an internal thread that can be screwed onto the outer thread of the lower container. In the interior of the upper container, the cosmetic product filled into a bottom open pot is isolated by a sealing foil. At the upper end of the upper container, a screw cap is provided for removing the mixture. The sealing plug has a rupture pin for the sealing film. The combination is delivered with only teilverschraubten containers, the Teilverschraubung is stabilized by a tearable safety device so that the Aufreißdorn does not reach the sealing film. To use the mixture of the two cosmetic products contained in the combination packaging, the containers are screwed further into each other after tearing off the securing device until the tear mandrel penetrates the sealing film and finally the Screw connection comes to a stop. Thereafter, the mixture is prepared by shaking, which can be removed after removal of the closure of the upper container.

The invention has for its object to provide a new combination packaging for at least two foods especially in the food and beverage industry, more concretely for consumers a cost-effective, easy to handle in use, logistically as beverage bottles transportable and providable, hygienic combination packaging to create the common provides food that is eaten, and to provide simple methods of making such combination packaging.

The object is achieved by a combination device made of plastic for at least two different foods, consisting of a bottle-like first container with closure and bottom, and at least a second can-like container placed below the bottom of the first container and with a the bottom portion of the first Container au Shen encompassing opening edge is united by a releasable positive connection with the first container.

In an expedient method for producing such a combined package, the procedure is as follows:

The first container is stretch-blown in such a way that, at least in the bottom region adjacent to the bottom, it is elastically deformable and has positive-locking elements in the bottom region. The second container is at least stretch blown with an upper opening edge having positive locking elements greater than the bottom portion of the first container, and is filled with the food in advance or at substantially simultaneous filling operations and then via a positive connection under the floor and outside in the bottom area of the first container fixed to the first container. The first container is either substantially simultaneously with the food, for. As a beverage, filled and set after setting the second container under pressure and closed, or filled and closed after setting the second container under pressure. The overpressure in the first container is adjusted so that at least the bottom region of the first container expands to the outside under reinforcement and possibly securing the positive connection in the opening edge of the second container.

Another convenient procedure is as follows:

The first container is stretch-blown with interlocking elements in the floor area adjacent to the floor. The second tank is equipped with an upper, open, positive locking element te opening edge greater than the bottom portion of the first container stretch blown, and is or is filled with the food and is below the bottom via a positive connection outside Shen in the bottom region of the first container set. The first container is or is with the food z. B. a drink, filled and optionally closed. At least in the area of the positive connection, a circumferential sleeve, an overlapped band, each with contraction bias, or a seal or coating is applied to reinforce or secure the interlocking connection.

With the combination packaging, which can be produced according to the appropriate procedures, a new packaging area in the food and beverage industry can be opened and is expected to be widely accepted by consumers who can usually buy jointly consumed food and / or drinks extremely comfortable. An important advantage of the combination packaging is a simple and inexpensive production with high production rate and a logistically handled transport and delivery, as with conventional beverage bottles, i. over boxes or in packs. Non-limiting examples of the combination packaging products to be offered to consumers together with beer and nuts such as peanuts, soft drinks and crisps, salad dressing and lettuce, milk and cocoa powder beverage and a flavor concentrate, and the like. The containers may have the pleasing appearance of a normal one in the combination package Mediate beverage bottle, wherein the volumes of the two containers may be the same or different, ie it may well be the first container substantially smaller or shorter than the second container, or vice versa. The combination packaging is stable, stable and hygienic. Its ingredients are recyclable as is standard with traditional plastic beverage bottles.

In an expedient embodiment, the first container has a deformable bottom area at least adjacent to the bottom, and the positive connection between the first and second containers is reinforced or secured by the first container at least in the deformable bottom area to the outside, expanding inside pressure in the first container. As a result of this use of the deformability of at least the bottom region of the first container, the second container can initially be conveniently provisionally fixed. Only after building up a correspondingly set overpressure in the first container of the positive connection is reinforced or secured by an expansion example of the underlying wall portion of the first container to the outside Shen. Under reinforced, for example, to understand that the positive connection is not or only with great effort to solve or at least secured so strong that it can not be solved automatically during transport and the like. In order to gain access to the second container, acceptance of the Close the first container, the pressure reduced, so that the deformation resets and then the second container can be easily removed.

In another expedient embodiment, the form-fitting connection is reinforced or secured by a circumferential sleeve or an overlapped band or a seal. The sleeve, the tape or the seal prevents uncoupled loosening or loosening of the form-locking connection. Only by increased force or removing or destroying the sleeve, the tape or the seal the positive connection is solvable. Preferably, the sleeve, the tape or the seal produces a bias acting from outside to inside, and / or a securing bond is provided. These structural features for reinforcing or securing the positive connection can be provided individually or in combination.

The good formability of plastic material for the first and second container bill, the positive connection can be a screw, a snap connection or a bayonet connection provided on both containers, can be brought into engagement positive locking elements. The interlocking elements can be mitgeformt easily in the production of the first and second container, z. B. by means of a provided in the stretch blow mold thread, z. B. a coarse thread, or the like.

Suitably, the first and second containers are made of PET as used for beverages and other foods, and are made by stretch blow molding. The second container is expediently laser-cut at its opening edge in order to obtain a precise and clean edge configuration, which prevents a risk of injury.

Suitably, the positive connection, optionally supported by an outer seal or Au ßenbeschichtung or the sleeve, tape or seal, even aseptically from to provide a high standard of hygiene.

In a further alternative, the second container is aseptically sealed below the opening edge by a tear-open lid or a tear-open foil, so that lower requirements must be placed on the positive-locking connection and its reinforcement or securing. The second container may already be pre-filled with the food in this embodiment and may be applied before or during or after filling of the first container.

In a further embodiment, the combination packaging can be widened by at least one further second container which, at the bottom side of the second container, is in the same position. rather like the second container on the first container. The second second container may optionally provide another food.

Particularly suitably, the combination packaging is suitable to provide in the first container a carbonated beverage, preferably beer, and the second container nuts, preferably peanuts, or chips, because these foods are consumed frequently and to a considerable extent together.

In an expedient embodiment, the sleeve, the band or the seal has at least one desired separation point. This can be, for example, a perforation or a tear-off tab and serves to be able to easily separate the first and second containers before the food is consumed.

In another embodiment, the sleeve, tape or seal on the outside is designed as a label or provided with a label that can carry brand and product instructions. In this way, the combination packaging no longer needs a separate label.

In a further expedient embodiment, the closure of the first container is a screw cap or a zipper or even a Dosage closure. A Dosage- closure may be useful, for example, for a precisely metered when eating food and can be made similar to, for example, in honey containers.

Although the combination packaging suitably plastic stretch blown container comprises, the design principle of the combination packaging is at least partially useful for glass or metal containers.

Reference to the drawings, embodiments of the subject invention will be explained. Show it:

1 is a side view of a combination package, are indicated in the dashed sub-variations,

2 a first detail solution,

3 a second detail solution,

4 shows a third detail solution, analogous to the solution of FIG. 1,

Fig. 5 shows a fifth detail solution, and 6 is an enlarged detail section of Fig. 1st

A combination package K shown in FIG. 1 for at least two different foods, for example beer B and peanuts E, consists of a first, bottle-like plastic container F, on the bottom side of which a second can-like plastic container D is fixed. For example, beer B is contained in the first container F, while peanuts E are contained in the second container D, for example.

The first container F has at a neck 1 a closure 2, z. As a screw cap, zipper or Dosage- closure, has an arbitrarily designed Au ßenwand 3 and a bottom 4. Adjacent to the bottom 4, the first container F in the Au ßenwand 3, for example, a restoring deformable bottom portion B on. In the bottom area B 3 form-fitting elements 6 are formed mainly in the Au ßenwand.

The second container D has, in an upper region 7 of an outer wall 8 adjacent to an open opening edge 23, the form-fitting elements 6 of the first container F matching interlocking elements 6 ', and a bottom 9.

The second container D is fixed with a positive connection V in the bottom region B of the first container F, such that the opening edge 23 engages outside in the bottom region B outside.

Dashed is not necessarily required detail variant, a sleeve 10 is shown, for. A shrunk plastic sleeve, a circumferentially extending, overlapped band, or a coating or seal, and externally mounted so as to extend upwardly and downwardly at least over the area of the interlocking connection V. Here, for example, a bond 13 may be provided. Furthermore, in an expedient embodiment, at least one perforation 12 (in the circumferential direction or obliquely) and / or a tear-off tab 11 can be provided for the holding, reinforcing or securing action of the sleeve 10, tape or the seal or outer coating to be able to break before releasing the positive connection V.

Dashed lines are also indicated that on the second container D on the underside another or second second container D can also be set with a positive connection V, which contains a still further food.

Suitably, the first and second containers F, D are made of PET and are made by stretch blow molding. The opening edge 23 can additionally by a laser cut be edited. The interlocking elements 6, 6 'can be mitgeformt during stretch blow molding of the first and second containers F, D.

The shapes and dimensions of the first and second containers F, D shown in Fig. 1 are not to be construed as limiting, but any shapes and capacities and relative sizes may be chosen. Suitably, however, the combination packaging K has a largely constant Au ßendurchmesser in the lower region, so that they can be handled like a standard plastic beverage bottle.

FIG. 2 shows a part of a detail variant in which the interlocking elements 6 in the bottom region B of the first container F are, for example, a thread with at least one thread 14. The matching second container D contains a positive internal thread as positive-locking elements 6 '(not shown).

In the detail variant in Fig. 3, the positive-locking elements 6 are formed in the bottom region B of the first container F for producing a bayonet connection. For example, it is grooves or beads 15, 16 which are compatible with at least one correspondingly shaped positive-locking element in the second container D. Here, several such positive locking elements can be provided in the circumferential direction.

In the detail variant in Fig. 4, which largely corresponds to the positive connection V shown in Fig. 1, is in the bottom portion B of the first container as part of the interlocking elements 6 a, z. B. closed in the circumferential direction, recessed z. B. rounded, groove, with a bottom-side adjoining, circumferential raised, also rounded bead 18. The opening edge region of the second container D is formed with mating form-locking elements 6 'in order to produce a positive-locking connection V latched by axial pressing. The outer diameter D of the first container F is, for example, slightly larger than the diameter D1 of the bead, so that the over-latched opening edge 23 of the second container D creates a substantially planar transition upwards.

In the detail variant in FIG. 5, a plurality of latching recesses distributed in the circumferential direction of the first container F in the base region B are formed as the form-fitting elements 6. Each latching recess 19 has, for example, an insertion bevel 20, a hooking edge 21 and a receiving recess 22. The positive locking elements 6 formed in the matching second container D are complementary, for example inwardly projecting noses, which can be hooked into the latching depressions 22. 1 illustrates, for example, reinforced or secured by overpressure generated in the first container F with a deformation of the bottom region B to the outside (arrows 24) and / or a bias from outside to inside (arrows 25) ) through the sleeve 10, the tape or the seal or coating.

In the positive connection V engages an inwardly raised bead 17 'of the second container D in the circumferential groove 17 in the bottom portion B of the first container F, while the circumferential bead 18 in a transition 18' snuggles. By reinforcing or securing the positive connection by overpressure (arrows 24) and / or contraction (arrows 25), the form-locking connection V is possibly even aseptic.

The interlocking elements 6 'of the second container D are axially interlocked in the positive locking elements 6 of the first container F by axial sliding taking advantage of the elasticity of the plastic material as predominantly the second container D in the upper opening edge region, wherein the opening edge 23 either slightly above the outer diameter the wall 3 of the first container F projects, or can be flush with this (not shown). The containers F, D are coaxially joined to each other.

Further, in Fig. 6 as a further alternative, a closure cover or a tear-open closure film 26 in the second container D is indicated, which may be an additional measure.

The positive connection V in FIG. 6 is produced in such a way that the filled second container D is initially snapped on, while the first container F is optionally filled but not yet pressurized. Then, the overpressure is generated and adjusted so that the deformation in the bottom portion B enters the outside before the shutter 2 is applied to hold the overpressure. Additionally, or alternatively, after attaching the second container D in the first container F, the sleeve 10, tape or coating is applied and contracted so as to reinforce and secure the positive connection V.

To remove the second container D, if overpressure was used, the overpressure is initially reduced by opening the closure 2, so that the deformation in the bottom region B returns. Then the positive connection V can be easily solved by axially pulling off the second container D. If the sleeve 10, the tape or the coating is attached, then the holding action of the sleeve 10, tape, or the coating is eliminated via the perforation 12 or the tear-off tab 1 1, so that the positive connection V is easily solvable. The respective form-fitting connection V can also be used without deformation and / or contraction, provided that it is stable enough without such aids.
