Description

The present invention relates to a double-chambered vessel for flowable substances.

It is known, flowable substances, which in particular liquids, but also viscous substances such as gels, creams, pastes or viscous foods such. As honey or syrup, store in double-chambered vessels. In this case, the individual chambers of the vessel are separated from each other, so that it is prevented that the flowable substances stored separately therein before coming out of the vessel come into contact with each other. Such separate storage is used in particular for different flowable substances, for various reasons. Thus, for example, there are two-component adhesives, each having different chemical components containing adhesive output pastes, which undergo a reaction by mixing and cure. These substances must be stored separately so that the curing reaction does not occur already takes place during storage and the adhesive or adhesive is unusable, but rather this reaction occurs only in the desired application to the mixing of the components out.

However, separate storage of different flowable substances are also known from cosmetics, where different components of care creams or the like should be mixed only immediately before use. The same applies to areas of medicine. In addition, it is known to store flowable food in double-chambered containers. This can be done, for example, to different starting materials z. B. a mixed drink, such as cola and beer, only to flow together immediately before consumption (see, for example, the utility model DE 296 00 895 U 1 which discloses a dual-chamber vessel having the feature of the preamble of feature 1). Finally, especially the stored in separate chambers presentation of different liquids with different coloring from the point of view of marketing interesting if the differently colored substances z. B. a dark and a light sugar beet syrup or the like in the consumer recognizable different chambers of a double chamber vessel storage.

Another double-chamber vessel, which should find application for liquid detergent, is in the DE 10 2006 036 637 A1 described.

Another double chamber vessel is in the WO 03/020601 A2 described. There, the individual chambers are arranged one above the other with overlapping areas.

These known from the prior art double-chamber vessels has in common that they are arranged clearly separated from each other and from a partition of mutually insulated chambers containing the presentation of the packed in the dual-chamber vessel flowable substances a relatively chunky impression at the consumer and in which the size of the Chambers that may vary depending on the content desired (see the above DE 29 600 895 U1 ) in their different size for the consumer are clearly perceptible. This type of presentation is often perceived as being "rough."

In the US 2006/0213854 A1 discloses a dual-chamber vessel in the form of a bottle in which an inner chamber is located entirely inside and without contact with the side wall of the vessel. This inner chamber is rotated helically, but can not contribute to the outer impression of the vessel, in this case the bottle, especially when in the surrounding the inner chamber volume of the bottle a non-transparent flowable medium is filled.

Here, the inventor has thought about an improvement that offers a possibility of more attractive presentation of the flowable substances filled in the dual-chamber vessel, and also greater independence of the design of the volume ratios of the two chambers with respect to a uniform or appealing exterior design and a such design of the double chamber vessel.

This object is achieved with a double-chamber vessel having the features of claim 1. Advantageous developments of this vessel are given in the dependent claims.

According to the invention, the dual-chamber vessel is constructed so that it has a first, inner chamber, which is surrounded by a second, outer chamber. The second, outer wall, which limits the outer chamber to the outside, is transparent and in particular forms the lateral outer wall of the double-chamber vessel. In that regard, the second outer wall completely encloses the chambers contained in the vessel.

Preferably, the first, inner wall is transparent. However, this can also be opaque or colored intransparent.

In this case, sections are formed, which are flat sections, and in which the wall of the first, inner chamber in the region of the lateral outer wall is directly connected to the wall of the second, outer chamber, so that between the walls of the first and the second chamber no longer remains to be filled with the flowable substance in the second chamber cavity, or in which the outer wall of the first chamber and the second chamber is formed by a common wall profile.

Due to the fact that the otherwise inner first chamber with its outer wall is guided in its sections to the wall of the outer chamber, in these regions in the case of two-chamber vessel filled with different flowable substances in the first and the second chamber, either the outer wall of the inner chamber or, if it is transparent, the flowable substance contained in the inner chamber visible from outside the vessel forth, even if the view of the inner chamber otherwise by a contained in the outer chamber, colored, cloudy or otherwise reason non-transparent liquid is covered. In particular, very variable optically pleasing effects can thus be achieved for the chamber vessel filled with different flowable substances in the two chambers. Is, as provided according to a development of the invention, the double-chamber vessel formed in the form of a bottle, this bottle, for example, with different liquids, eg. B. in the inner chamber with cherry juice, filled in the outer chamber with banana juice. The cloudy and yellowish-beige banana infusion in the outer chamber conceals in this example the view of the dark red cherry juice stored in the inner chamber, wherever the wall of the first inner chamber is not brought to the wall of the outer chamber. There, the viewer of the double-chamber vessel sees the red cherry juice. It is very easy to recognize at this point that this type of embodiment of the double-chamber vessel brings with it a high degree of flexibility with regard to the design. It is only necessary to ensure that the second, outer chamber is still connected as a whole and continuously with its opening and can be emptied by this of the flowable substance. For example, the flat sections, in which the first chamber with its wall directly against the wall of the second chamber, be formed circular (with a curved wall of the outer chamber in the form of corresponding projections), said circular sections on the bottle regularly or distributed in different patterns could be. As well, these sections may be formed as "islands" of different geometry, angular, star-shaped or the like. Also contemplated is a continuous formed surface of the sheet-like sections, which in the external view spirally along the wall of the second, outer chamber, which also forms the lateral outer wall of the double-chamber vessel, along pulls.

Depending on how fluid the flowable substances are in the chambers of the dual compartment vessel, the walls may be stiff (eg, in liquids) or flexible (eg, for viscous pastes to be transported by pressing from the dual compartment vessel).

It should be understood that without an optical change in the chosen design of the arrangement and geometry of the sheet sections in which the first chamber with its wall is directly adjacent to the wall of the second chamber, volume ratios of the first chamber and the second chamber are adjusted and changed can. This can in particular very easily be done by changing the wall course of the first chamber in the areas in which this wall is not applied to the wall of the second chamber. As this wall is drawn further inward into the interior of the dual chamber vessel, the volume of the first chamber becomes smaller and the volume of the second chamber larger and vice versa. Accordingly, therefore, by adjusting the volume ratios of the two chambers optionally with simultaneous adjustment of the opening widths of the openings a mixing ratio of the two separate stored and for mixing together expiring flowable substances can be adjusted when they are released from the double chamber vessel or pushed out of this. If, for example, separate milk and an additive for producing a milk mix beverage (a cocoa product, a milk mixed with fruit syrup or the like) are stored in such a double-chamber vessel, then the milk can be stored in a larger selected volume of the inner chamber, the additive in one small selected volume of the outer chamber. By the appropriate attitude of the two chambers and the orifices chosen in consideration of the desired mixing ratio as well as the different viscosities of the starting ingredients can be achieved so that the milk mix beverage flows out of the dual chamber vessel in a predetermined mixing ratio so that it has the desired flavor characteristics. When emptying the double-chamber vessel, both the inner first chamber and the outer second chamber empty with skillful dimensioning to the same extent, so that the impression from the outside can appear even emptying of the vessel itself.

A variant to implement such a design, is the flat sections, in which the first wall of the first chamber on the second wall of the second chamber directly abuts or is formed together with this, seen from the outside in a continuous spiral shape along the Outer wall of the double-chamber vessel extends to form.

Alternatively, however, the dual-chamber vessel according to this invention may also be formed as a perfume or perfume bottle. Then, an atomizer, in particular a pump sprayer known per se, is advantageously arranged in the opening section, which reaches the openings of both chambers and via which the chambers can be emptied. The atomizer can emptying both chambers simultaneously via a corresponding switch. Alternatively, and in a particularly preferred variant, the atomiser can alternatively be connected to the first or the second chamber by means of a suitable switching mechanism, in order to deliver only the contents of one of the chambers. Thus, for example, in a vial in a visually appealing manner of a fragrance an Eau de Toilette (typically in a larger volume chamber, eg the first chamber) and a perfume (typically in a chamber of lesser volume, eg the second chamber) are offered at the same time ,

In principle, the implementation of a double-chamber vessel according to the invention offers a high degree of design freedom with regard to the ratios of the externally visible surfaces of the first and second chambers and the volume ratio of the volumes of both chambers. The latter can be particularly independent be adjusted from said surface ratio by the relations of the chamber volumes are selected by different extensions or expansions of the chambers in the interior of the vessel.

For the presentation and a particular relationship of the different areas and thus contained in the chambers containing flowable substances impression has a ratio of the surface of the lateral outer wall, on which the outer wall of the second chamber rests or forms the surface to which the Outside wall of the first chamber is exposed, without that the outer wall of the second chamber is applied to this, between 4: 1 and 1: 4, in particular between 3: 1 and 1: 3, preferably between 2: 1 and 1: 2 as suitable and to be emphasized.

Particularly preferred, since easy to manufacture and associated with low weight, in particular in the realization of the vessel as a bottle, in particular beverage bottle, the wall of the first and the second chambers formed of a transparent plastic, in particular PET. Other plastics which are used in the packaging industry for the respective applications (eg bottles, tubes or the like) which can be used as a double-chamber vessel according to the invention are also suitable here. From such a plastic material can, for. Example, in a manner according to the invention designed as a double-chamber vessel bottle are prepared by first the inner chamber formed by drawing or injection molding and then enclosed in a second manufacturing step with the outer chamber, the z. B. can also be produced by injection molding. In principle, the chamber walls and thus the double-chamber vessel can also be made of other suitable materials, such as e.g. Glass, as it is preferred for higher quality vessels, especially perfume flacons.

Advantageously, the double-chamber vessel has a closure that jointly opens the first and the second chamber, which openings jointly open in the opening section, and in particular can be a screw cap in the case of a bottle. In particular, this closure is arranged and cooperates with the shape of the vessel in the opening section, that it closes both openings separately in the opening section, so that even with transport-related movements and changes in position of the double-chamber vessel a passage of the stored in a chamber of the vessel flowable substance is excluded in the other chamber. In the case of a bottle, the atomizer is advantageously the closure of the two chambers.

The openings of the first and second chambers may in particular be formed such that the opening of the first, inner chamber is circular and is concentrically surrounded by the annularly formed opening of the second, outer chamber. In this arrangement, when emptying the double-chambered vessel, the two separately stored flowable substances are mixed, and by designing the area ratios of the area of the circle of the inner opening and the ring of the outer opening, further, a desired discharge ratio of the two flowable substances of the first and second Chamber can be adjusted.

In particular, when the sections in which the wall of the internal chamber lies against or coincides with the wall of the external chamber have a complex geometry which allows a flow of the flowable substances stored in the external chamber in the regions between them It may be advantageous if sections make it possible to create at least one second path with which the second outer chamber is connected to the associated opening of this chamber. Such a second way may be, for example, in the case of the embodiment already described above, with a portion of collapse of the wall or walls of the first and second sections extending spirally along the outer wall of the vessel, a channel-shaped incision in which this spiral-shaped surface is interrupted and a channel run is formed between these sections for connecting the opening facing away from the region of the chamber with the opening. In this case, however, it also comes into consideration in the interior of the vessel, inside the first chamber in the direction of the opening area, connected to the second chamber, in particular in a section which is at the maximum opposite the opening area.

The figures schematically show possible embodiments of a double-chamber vessel according to the invention, the invention not being limited to these specific embodiments and their geometries. The figures are neither true to scale, nor faithful in all structural details, but represent rather schematic representations sketchy nature.

First, referring to the FIGS. 1 to 3 a first embodiment described. In the FIGS. 1 a and 1 b is a double chamber vessel 1 for flowable substances each shown in a partially cutaway view, wherein the views according to Fig. 1 a and Fig. 1b differentiate in the different far away cut areas.

The double-chamber vessel 1 is in this case a bottle, in particular beverage bottle, with a bottle bottom 2, an elongated bottle body 3 with a lateral outer wall and a bottle bottom 2 opposite to the top of the double-chamber vessel 1 opening portion 4. This opening portion 4, as in such Bottle-like vessels usual, closed by a screw cap, not shown here, so that the one or more contained in the double-chamber vessel 1 and enclosed by this cavity or cavities or chambers (see below) can be tightly sealed to leakage or flow to prevent the flowable substances from the interior of the dual-chamber vessel 1.

The double-chamber vessel 1 contains completely enclosed by an outer wall 5, a further, inner wall 6, which encloses an inner chamber. This inner chamber, which is delimited by the inner wall 6, has an opening 7 located in the opening area 4.

The outer wall 5, which completely encloses the inner wall 6, and the inner wall 5 define between them a second, outer chamber, which also opens in the opening portion 4 in an opening 8, wherein the opening 8 annular slit-shaped and concentric around the opening 7 is guided around.

In accordance with the invention, the outer wall 5 is connected in areas 9 directly and without leaving an intermediate cavity with the inner wall 6; in other areas 10, the outer wall 5 is guided away from the inner wall 6 to form an intermediate cavity forming the outer chamber.

In this embodiment, this is so designed that the regions 10 continuously complement each other to form a spiral or helical profile over which the outer chamber along the bottle-shaped double-chamber vessel 1 via the lateral outer wall starting from the bottle bottom 2 to the opening portion 4, is guided exactly to the opening 8. In the case of the double-chamber vessel 1 according to the invention, in particular the outer wall 5 is designed to be transparent, wherein preferably also the inner wall 6 can be made transparent. Due to the transparent design of the outer wall 5 is given in the different areas 9 and 10 each have a different view. Through the areas 10, the observer sees from the outside when the second chamber is filled, the contents arranged in this chamber, the corresponding flowable substance, for example a colored juice or a colored lemonade. In the areas 9, the viewer immediately takes the inner wall 6 located below the outer wall 5, if this is not transparent, but colored or opaque, or through this inner wall 6 through the contents of the inner chamber, such as a juice or lemonade true in another color. In the overall impression, this results in a two-color impression, which in the illustrated embodiment of the double-chamber vessel 1 has a color-changing, spiral course.

In the variant of a double-chamber vessel 1 shown here, it is particularly possible, by the design of the distance between the outer wall 5 and the inner wall 6 in the region 10 in which the cavity remains between these walls 5, 6, the respective volume of the inner and outer Vary chamber and thus adjust the ratio of these two volumes. Thus, e.g. a mixed beverage, which is to arise only when flowing out of the double-chamber vessel 1, are stored separately in its constituents, wherein at the same time the mixing ratio is predetermined by the ratio of the volumes of the inner chamber and the outer chamber. In order to achieve a corresponding outflow from the respective openings 7 and 8 in such a mixing ratio, the ratio of the opening cross sections of these openings 7 and 8 can also be adjusted accordingly.

In order to facilitate an outflow from the here shown spirally along the double chamber vessel 1 extending outer chamber volume in the double chamber vessel 1 shown here can (not shown here) in a direction substantially perpendicular to the course of the spiral path of the outer Chamber a ventilation web to be performed, in which the connection of the outer wall 5 with the inner wall 6 repealed in the areas 9 and thus a direct flow of air is made possible when emptying the volume of the outer chamber.

In Fig. 2 is shown in enlarged scale, the upper portion of the dual-chamber vessel 1 with the opening portion 4, to once again illustrate the position of the opening 7 to the inner chamber and the opening 8 to the outer chamber in their orientation to each other. Good to see here are again the areas 9, in which the outer wall 5 abut the inner wall 6 directly and omitting a cavity, in contrast to the areas 10, in which there is a distance and so the volume of the outer chamber is formed.

In Fig. 3 Finally, it is again shown in a kind of exploded view, as the double chamber vessel 1 according to the invention equally composed of a bounded by the inner wall 6 inner vessel and an inverted over this, bounded by the outer wall 5 outer vessel. Good to see is also the spirally coiled incision, in which the inner wall 6 of the inner vessel springs back and later in connected to the inner wall outer wall 5 so the volume of the outer chamber, which runs spirally along the longitudinal direction of the dual chamber vessel 1.

In Fig. 4 is shown in a sectional perspective view of a second embodiment of a double-chamber vessel according to the invention and designated 20 there. Basically, this double-chamber vessel 20 is constructed analogously to that previously shown and described. It has a bottle bottom 22, a bottle body 23 and in an area opposite the bottle bottom 22 along the longitudinal axis portion an opening portion 24. This also has an outer wall 25 and an inner wall 26. The outer wall 25 encloses a first chamber, wherein separated from this first chamber in a region between the outer wall 25 and the inner wall 26, a second chamber is formed, which in regions 29 on the outer wall rests and there forms the surface of the lateral outer wall. These areas 9 together form a spiral-like continuous band, as is already the case in the previously described embodiment.

What is new here is that a further opening 31 is provided in the opening area 24, with which a tube 30 arranged in the interior of the first chamber of the double-chamber vessel 20 opens in the opening area. The tube 30 is connected in the region of an orifice 31, which is located near the bottom of the bottle 22, with the second, between the inner wall 26 and the outer wall 25 formed chamber. Thus, this chamber can optionally be emptied through the opening 21 or the opening 27, wherein air can flow over the respective other opening for venting the chamber.

In Fig. 5 is shown in partially cutaway view of another embodiment of the invention. Here, the dual chamber vessel 40 is a bottle for perfume or the like perfumes. As in the examples previously shown, an outer wall 45 and an inner wall 46 are provided, wherein in the interior of the double-chamber vessel 40, a first chamber is formed and a second chamber between the inner wall 46 and the outer wall 45 is. The inner wall 46 is guided in regions 49 to the outer wall (cut away there), which spiral in total around the vessel.

Arranged in an opening region 44 is a pump sprayer 41, which communicates with the volumes enclosed therein via corresponding hoses guided into the first and the second chamber, respectively. Here, the pump sprayer can be switched here by turning so that it is either in operative connection with the reaching into the first, inner chamber tube or with the hose, which projects into the spirally wound second, outwardly guided chamber. So can be taken with the spray head optional content of one or the other chamber and sprayed. In this variant of the invention, for example, in the first inner chamber with a larger volume Eau de Toilette of a fragrance was located, in the between the inner wall 46 and the outer wall 45 formed second, in volume lower chamber a perfume of the same fragrance. But it could also be filled by a scent provider in the volumes scents for the man and for the woman, for example, to allow couples to share a "couple bottles". Then, by means of the above-described measure of an expansion of the volume of the second chamber, by displacing the inner wall 46 into the interior of the vessel, a corresponding adaptation and selection of the volume ratio could be made.

The embodiments shown here in the figures are to be understood as possible embodiments of the invention and to explain the same. In particular, there are very different and differently shaped forms of inventive double-chamber vessels, in which the geometry of the areas designated in the above embodiments 9, 29 and 49 (those areas in which the outer wall 5, 25 and 45 directly with the inner wall. 6 , 26, 46 are connected) and 10 (those areas in which between the outer wall 5, 25 and 45 and the inner wall 6, 26, 46 lead a distance to the formation of the volume of the outer chamber leaded) are designed differently. For example, the regions 5, 25, 45 may extend in a point-like manner across the dual-chamber vessel or may take a completely different course (e.g., crosses, hearts, stars, or the like). Also, the invention is not limited to bottle-shaped vessels or bottles. Thus, the dual compartment vessel may take other forms, such as e.g. Tubes for cosmetics or pasty foods.
