The secondary chamber completely encloses the main chamber. Between the main chamber and the sub-chamber, an auxiliary sealing edge is located, which is in the same plane, wherein the covering membrane with the auxiliary sealing edge forms an airtight auxiliary seal or is to be pressed against the sealing lip by the main seal is formed under a bias and product removal without pressure build-up and by removing the cover membrane from the dual-chamber cup.

Description

Technical area:

The The invention relates to a dual-chamber cup or container Plastic, a composite foil, or plastic and composite foil combined, or similar Material consisting of a main chamber and a secondary chamber and for a separate storage two donut types (components) is intended to be mixed before use to a product can, without opening it, These products are made of all sorts Areas can come such as. Food sector, household chemistry, cosmetics, etc., also from areas where a component in an oxygen-impermeable chamber is to be kept while the other component is in an oxygen-permeable chamber must, as is the case with most hair colors, and that in it the two components are mixed completely just before use can, according to the generic term of patent claim 1, the method of its design according to claim, its inventive filling with the components and closing according to claim, and a method for mixing the two components into one Product according to claim.

State of the art:

Such dual-chamber cups are used, for example, for packaging smaller snacks or desserts. Thus, in such cups, yoghurt is usually packaged in the main chamber and a jam preparation or the like is usually packaged in the auxiliary chamber. The two chambers are closed by a cover membrane mounted airtight on it. For transferring the cover membrane must be deducted and the contents of a secondary chamber, after its kinking along a prefabricated bend line, are transferred to the main chamber. Such dual-chamber cups are inter alia in the German patent application P 37 15 442 and in the German utility model 83 29 744.8 described.

Further is such a dual-chamber cup from the OS 37 41 939 known.

All of these designs have the disadvantage that even when transferring a granular content a side chamber in the main chamber, his remains remain on the Bridge arranged between the main chamber and the auxiliary chamber is, lie when the secondary chamber is suitably overturned. Will the Contents of the secondary chamber sticky, such as jam, prepares the transfer still more problems.

Also a complete Refilling a sticky content e.g. Honey from a side chamber in the Main chamber, is virtually impossible since this on their walls sticking, which is also a major disadvantage of these solutions.

Become in a chemical product, for example, a hair color, not the entire contents of the two chamber mixed together, so vote the mixing ratios the two component does not match the given one. As a result, the end result is the expected hair color is not achieved, which is also regarded as a major drawback of the current solutions is.

proof for this, that this problem with yogurt is still unsatisfactory solved is, for example, that in television advertising for such Yogurt products whose components are stored in two compartments, never a refill a sticky content from a secondary chamber into a main chamber was shown, but one is always limited to a practiced, retrograde Kinking and overturning of a free-flowing, dry component, for example, an older one Human with limited Motor can not imitate.

As practice shows, especially older people have a big problem with the transfer of a sticky component from a secondary chamber into a main chamber, so that up to 30% of the secondary chamber content can not be consumed, which is also to be regarded as a disadvantage, since the intended mixing ratios can not be met.

Important Feature of the invention is that regardless of whether a dual-chamber cup or Double chamber container is made of the same material and made in one piece becomes, or that the main chamber and the auxiliary chamber from different Materials exist and expedient with each other It is always important to make sure that you are doing something wide auxiliary sealing edge and main sealing edge arise.

Further Task is in a dual-chamber cup or dual-chamber container above genus according to the invention achieved in that two chamber for the storage time with one and the same covering membrane airtight from each other are separated and that this separation by means of an auxiliary seal, which is located between the main chamber and the secondary chamber takes place and up until a double-chambered cup or a dual chamber container, axially in the length stretched and thus converted into a mixing cup or mixing container being while being this process first the auxiliary seal must be dissolved without the covering membrane, the auxiliary sealing edge or the main seal to damage and subsequently the secondary chamber should be straightened so far as possible utter Mixing of the two components is guaranteed.

Further Object of this invention is in a dual-chamber cup or Double chamber container of the type mentioned above solved according to the invention that between an auxiliary sealing edge and a cover membrane, no seal is to form, but only by means of an appropriate tightening the cover membrane at an auxiliary sealing edge, a sufficient separation of the two Chamber, is to produce. For this kind of separation of a main chamber from side chamber is the auxiliary siren edge, especially with a rounded cross-section or with a sealing lip To provide this type of separation mainly for round double-chamber cups or dual chamber containers is applicable.

Around to increase the pressing of the covering membrane to the auxiliary sealing edge, is provided according to the invention, that a main sealing edge is arranged lower than an auxiliary sealing edge must and that before the formation of a main seal, the secondary chamber slight is to put up to produce a predetermined bias. To which the main seal has reached its final form is To relax the secondary chamber, thus the previously generated bias to transfer to the cover membrane and to increase their contact pressure on the auxiliary sealing edge. such inexpensive Separation is mainly used in yogurt cups or the like, the while of transport only slightly change their position.

According to the invention is possible, too, that the shell of a dual-chamber cup or a dual-chamber container, in an injection molding process as a thin-walled Elements can be produced and then, if necessary, can a desired one Chamber by means of an additional Treatment, such as spraying or lining with a Barrier film, made impermeable to oxygen become.

Both can according to the invention Chamber also made separately and made of different materials be, and in particular before filling, airtight with each other making sure that the connection areas appropriate to each other to be agreed.

Further is for this invention important that a cover membrane of any Material, for example from a coated aluminum foil or consists of a plastic film, and the requirements, to Example impermeable to oxygen, and that this is at least with a main sealing edge by means of one of the known methods, for example an ultrasonic device, permanently and appropriately connectable is.

Another embodiment of the invention provides that a membrane, in particular of a plastic film, an eyelet or the like, by means of this at least one auxiliary seal aufgeho ben can be, and a dual-chamber cup or dual-chamber container can be transformed into a mixing container.

Important Feature of the invention is that by an elastic and / or plastic Deformation of a dual-chamber cup or dual-chamber container and thus reducing the negative pressure in it, is the covering membrane to book out, independently of whether the auxiliary sealing edge is positioned higher than the main sealing edge or Not.

additional Feature of the invention is that with a corresponding pressure build-up, especially in the main chamber of a dual-chamber cup and if the covering membrane over this is tightly fastened, increasing its axial rigidity can be.

Becomes the dual-chamber cup or dual-chamber container according to the invention by its axially executed Stretch converted to a mixing container, First, the notched portion of a cover membrane in it shift and then repeal the auxiliary seal expediently during this transformation, what a plastic and / or elastic deformation of a dual-chamber cup or dual chamber container reduced accordingly, that is, the larger the bulge, the more smaller the elastic deformation of a double-chambered cup or a dual chamber container.

Important Feature of the invention is that the auxiliary sealing edge of the main chamber separated from the secondary chamber, higher may be arranged as the main sealing edge, whereby, for example a better sealing of the two chamber during filling is possible and what especially when filling a Secondary chamber with dry, dusty ingredient is important for this for example, can not get to yogurt, which in turn on the Storage time, which means the better the separation this, the longer Storage time possible.

According to the invention the covering membrane for The two chambers are to be designed so that they can be connected to one another Auxiliary sealing edge around the main chamber as well as at the lower lying Main sealing edge around the secondary chamber, after the appropriate filling, airtight and permanently attachable, wherein the auxiliary seal formed thereby always weaker must be as the main seal with it corresponding to the conversion of a dual-chamber cup or dual-chamber container into a mixing cup or mixing container to guarantee before this opened becomes.

A further advantageous embodiment The invention provides that a dual-chamber cup or dual-chamber container is the same height instructing main crucible edge and sub sedge edge, in particular, if a secondary chamber is plastically easily deformable and with their corresponding main chamber has greater stability.

Further The object of the invention is in a dual-chamber cup or dual-chamber container of The aforementioned type inventively achieved in that Its forming, by means of an axially performed pulling on an eyelet, the for example, is attached directly to a cover membrane at arrested main chamber, or vice versa, is reached, whereby first an auxiliary seal, if any, is to be solved and then the Secondary chamber permanently as far as to deform and / or unfold is until one possible utter Amount of component stored separately until now when mixing them to a product that participates, being the transition of a double-chambered cup or dual chamber container to a mixing container, its total density may not adversely affect.

According to the invention depends Degree of elastic deformation of a double-chambered cup or a Double chamber container to a mixing cup or mixing container, from the difference (T) between the position of an auxiliary sealing edge and a main sealing edge, as well as from the height the secondary chamber (h), that is the bigger the Difference (T) and the smaller the height (h), the smaller change the shape of a dual-chamber cup or dual-chamber container to is expected. Very important is that the height (h) of a secondary chamber always is larger as the difference (T), hence a clean resolution of an auxiliary seal always can be done. Also very important for this invention is that after forming a dual-chamber cup or dual-chamber container too a mixing cup or mixing container, a small, elastic bias is build up, which in their initial opening should be loose and thereby absorb a small amount of air, to an unwanted removal of a product to the outside, targeted to prevent.

These important features of the invention apply to both a dual-chamber cup or dual-chamber container or any other form of egg ner double-chamber packaging which is subject to the protection of the invention.

Very important feature of the invention is that always a sampling of a product, the opening a mixing cup or mixing container to adapt. If, for example, a double-chambered cup for yogurt the main seal must be designed so that the Cover membrane after completion of mixing, effortlessly remove, to get to the yogurt.

These it is a double-chamber container, for example for a hair color, from the after its conversion to a mixing container, the product removal by means of a spout done with detachable tip, the main seal must be between a cover membrane and the main sealing edge of a secondary chamber corresponding to it be so firm that it remains permanently connected until the end. Also the quality the cover membrane is to be designed accordingly.

• – bei einem Doppelkammer-Becher: 1) bei weitgehendem Beibehalten der jetzigen, aus dem Stand der Technik bekannten Form eines beispielsweise Joghurt-Bechers oder dergleichen, kann der Joghurt und die Beimischung, separat und mindestens flüssigkeitsdicht voneinander solange aufbewahrt werden, bis diese zusammengemischt werden sollten; 2) der Mischvorgang des Joghurts und der Beimischung erfolgt im geschlossenen Doppelkammer-Becher, in dem dieser zu einem Mischbecher umzuwandeln ist; 3) erst nach einem abgeschlossenen Mischvorgang ist der Mischbecher zu öffnen, in dem die Abdeckmembrane von ihm zu entfernen ist, wobei dieser Vorgang am Anfang recht vorsichtig durchzuführen ist, bis der Mischbecher sich elastisch soweit entspannt, dass kein Spritzen eines fertigen Produktes erfolgt.
• – bei einem Doppelkammer-Behälter: 4) die beiden Kammer können gleiche Eigenschaften aufweisen, oder unterschiedlich gestaltet werden, beispielsweise eine Sauerstoffbarriere aufweisen, so dass sie insbesondere zum Aufbewahren von Produkten wie zum Beispiel Haar-Farben sich eignen, da die Fixiermilch in einer sauerstoffdurchlässigen Kammer aufzubewahren wäre, während die Haarfarbe in einer sauerstoffundurchlässigen Kammer verstaut werden kann; 5) der Mischvorgang der beiden Komponente, zum Beispiel zu einer Haar-Farbe, erfolgt ohne einen Doppelkammer-Behälter öffnen zu müssen, das heißt, ohne die Abdeckmembrane zu entfernen; 6) das Öffnen eines Doppelkammer-Behälters erfolgt entweder durch die Entfernung einer Abdeckmembrane oder zum Beispiel durch ein Abschneiden einer Tülle-Spitze oder durch Abschrauben einer Abdeckkappe, oder dergleichen.

In general, the main advantages of the invention are defined as follows:

• In a dual-chamber beaker, 1) while substantially maintaining the present prior art form of, for example, a yogurt beaker or the like, the yoghurt and the admixture may be stored separately and at least liquid-tight from each other until blended together should; 2) the mixing process of the yoghurt and the admixture takes place in the closed double-chamber cup in which it is to be converted into a mixing cup; 3) only after a completed mixing process, the mixing cup is open, in which the covering membrane is to be removed from him, this process is to be carried out very carefully at the beginning until the mixing cup relaxed elastically so far that no spraying of a finished product.
• In a dual-chamber container: 4) the two chambers may have the same properties, or be designed differently, for example have an oxygen barrier, so that they are particularly suitable for storing products such as hair colors, since the fixative in an oxygen-permeable Store the chamber while the hair color can be stowed in an oxygen-impermeable chamber; 5) the mixing process of the two components, for example to a hair color, without having to open a dual-chamber container, that is, without removing the cover membrane; 6) the opening of a dual-chamber container is carried out either by the removal of a cover membrane or, for example, by cutting off a spout tip or by unscrewing a cap, or the like.

Furthermore, important feature of the invention is that the now necessary, Spaces known from the prior art are substantially reduced here, since no transfer a component must take place, but the volume of the two Chamber is available during the mixing process, albeit in one changed Form, whereby a transport volume as well as an outer packaging of a Double-chamber cup according to the invention or dual chamber containers requires a smaller volume, which has as a consequence a financial saving.

Further particularly preferred embodiment of Invention provides that a main chamber of a dual-chamber cup or Double chamber container, much more stable than its corresponding secondary chamber to shape is. Of course the main chamber must also be elastically deformable to the extent that a convenient product removal always guaranteed, which is especially important for a hair color.

A further, particularly preferred embodiment of the invention provides if the shell of a dual-chamber cup or a dual-chamber container is extra thin too but does not have a stabilizing paperboard casing, is their axial stability thereby increase that the cover membrane under bias on the Main chamber and the secondary chamber is to install and that they are closes so tightly, the trapped air has a stabilizing effect.

By a permanent, axial pulling apart a dual-chamber cup or double chamber container, first, the free area of the covering membrane shifts into its Outline and then dissolves the auxiliary seal between the auxiliary sealing edge and the cover membrane Completely on. When pulling it further apart must have such a straightening the secondary chamber done that a predetermined mixing of the two Component is guaranteed.

Any further, arbitrary combination of the above individual features with each other is subject to the protection of the invention and is its important part of survival, regardless of whether this relates to a cost double-cup, double-chamber container or other type of packaging, the first of two chambers consists, by means of one and the same Abdeckmem brane are hermetically sealed and later converted to a mixing cup or mixing container, this conversion takes place without opening the cover membrane and that from which the product removal by removing the covering membrane or by opening, for example, a spout occurs.

Based the attached Drawings, the most preferred embodiments of the invention show, but not limit the invention, it will now be described in more detail.
