For this purpose, the container comprises an opening in the front part which is extended into the interior of the container by means of a cannula. The cannula has one or more openings in the interior of the container on the side wall. The active ingredient preparation (s) are filled in the area of the container which results from the cannula and the container wall. The basic preparation fills the rest of the container.

Description

The invention is a kit comprising a container with a multicomponent preparation, one component comprising perfume and / or one or more active ingredients. This active ingredient preparation is stored on the edge of the container and can be applied in strip form (visible but also invisible) with the other preparation components.

Colored striped toothpastes are known.

Multi-phase, i.e. multi-colored toothpastes, for example, have one or more window inserts in the tube opening. By applying pressure to the tube, the phases emerge at the same time and create a striped tube strand.

The strip insert is a so-called insert, which is placed on the shoulder inside the tube or is molded onto the tube during manufacture. This insert is mainly used in the oral care segment, for example for two-tone toothpastes. It is a small tube that has a large opening in the middle and several, for example five, smaller openings on the sides. The base mass is conveyed out through the middle and the colored strips are placed on the toothpaste through the small openings on the side.

The two formulation components can be dispensed simultaneously in controlled amounts from a container, such as a squeezable tube, by applying pressure to the components, which pressure is activated by the user. According to the invention, the pressure is exerted on the container walls. Containers suitable for this type of dispensing are known in the art, for example as described in U.S. Pat US-A-4 687 664 or UK 962757 is revealed.

In the toothpaste sector, for example, such technologies are in the EP 76563 A1 , DE 9404611 U1 or EP 1137392 A2 described.

In the cosmetic or pharmaceutical sector, preparations are often used which contain constituents whose contact with the other preparation constituents is to be avoided or whose contact time during storage is to be minimized.

For example, perfume constituents or cosmetic or pharmaceutical active ingredients are impaired in their stability by other preparation constituents, such as, for example, preservatives.

Usually, perfumes or active ingredients are mixed uniformly in a cosmetic or pharmaceutical preparation, so that the same proportions or proportions of perfume / active ingredient are always output when the product is dispensed.

When blending, mixing with the other ingredients of the preparation, however, on the one hand there is an input of energy and on the other hand there is increased air / oxygen contact through the mixing.

However, high energy input and increased contact with oxygen lead to instabilities and problems with perfumes or active ingredients that are sensitive to oxidation.

It is therefore desirable to avoid these problems.

Furthermore, it is desirable to keep the amount of perfume or active ingredients as low as possible, on the one hand to reduce the problems mentioned and on the other hand to also minimize costs.

A simple reduction in the perfume / active ingredient proportions, however, leads to the desired effect, a perfuming or the effectiveness, also being reduced.

It is therefore desirable to provide a cosmetic, dermatological or pharmaceutical preparation containing active ingredients / perfume which, while remaining effective, contains less perfumes or active ingredients.

The invention is a kit formed from a container (1) , for example a tube, and a multi-component preparation, in particular a two-component preparation. The preparation components differ in that at least one preparation component contains one or more perfumes and / or active ingredients, hereinafter referred to as the active ingredient preparation (7) designated. The other, a preparation component, comprises the basic preparation (8th) .

The container (1) comprises an opening in the front part (4) that by means of a cannula (5) is extended into the interior of the container. The cannula (5) has one or more openings in the interior of the container on the side wall (3) on. The cannula is delimited at the ends by a dispensing opening (4a) and an inner opening (4b).

The cannula (5) is in principle a pipe with open ends (4a, 4b) and openings located on the pipe wall (3) .

The container (1) comprises the multi-component preparation in such a way that the active substance preparation (s) (7) according to the invention in the area (2) of the container are filled. The area (2) arises between the container wall (6) and cannula side wall (5) in the front area of the container. In this area, the active ingredient preparation (7) placed. The area (2) is thus maximally predetermined by the length of the cannula, but can be designed to be variable in size, for example solely through the amount of active ingredient component (7) which is filled in the front part of the container. Ideally, the length of the cannula and the resulting space between the cannula and the container wall are dimensioned in such a way that the amount of active ingredient preparation is exactly in this space (2) Takes place.

The area (2) , which is the active ingredient component (7) includes, can in another embodiment also through the container wall (6) , the cannula (5) and one or more partitions (11) be divided, for example, to accommodate different active ingredient preparations (7a, 7b, ...).

The active ingredient preparation (s) can also (7) from the rest of the basic preparation (8th) , which is advantageously designed without perfume / active ingredient, by means of a separating device (9) be limited. The separator (9) separates the active ingredient component (7) from the basic preparation (8th) . The separator (9) consists preferably of an expandable or in the direction of the container opening (4) movable material.

By that the area (2) , in which the active ingredient preparation is present, at least through the cannula side wall (5) and the container wall (6) is limited, the active ingredient preparation (7) cannot be dispensed through the inner cannula opening (4b).

The basic preparation (8th) , which is advantageously prepared without perfume or active ingredient, fills the rest of the container.

When the container is squeezed out, a preparation strand becomes the preferably unperfumed or active ingredient-free basic preparation (8th) via the cannula (5) from the opening (4) applied. Because of the openings (3) in the cannula (5) and the pressure on the preparation components ( 7th , 8th ) are through the openings (3) one or more strips of the perfume / active ingredient preparation (7) with applied.

The container (1) is preferably malleable in order to enable the required application pressure on the preparations. In another embodiment, the container is (1) dimensionally stable. In this embodiment, a stamp can be attached to the end of the container (10) be attached via which the necessary pressure can be generated on the preparation components.

With the help of the number, location and size of the openings (3) in the cannula (5) as well as with the help of the size of the area (2) , which is determined by the amount of active ingredient preparation (7) or by the length and circumference of the cannula and the wall of the container (6) and, if necessary, separating device ( 11 , 9 ) results, the amount of perfume or active ingredient applied can be controlled individually.

The preparation components ( 7th , 8th ) advantageously each have the same or similar consistency / viscosity in order to form an extrudable, shape-retaining product that can be pressed out of a tube.

Similar viscosity means that the active ingredient preparations (7) by a maximum of 10% from the viscosity of the basic preparation (8th) differentiate.

Surprisingly, with the aid of the separation according to the invention of the preparation components and the application according to the invention, the amounts of perfume or active ingredients can be reduced without any loss of effectiveness.

According to the invention, the contact area between the preparation components is kept small or can be achieved by means of a separating device (9) , Slide, to be avoided entirely.

By means of the kit according to the invention, there is no scattering of the perfume or active ingredient in the rest of the basic preparation composition. Rather, the perfume / active ingredient components are provided in concentrated form in a primarily small part of a preparation component, the active ingredient preparation.

Numerous advantages are thus achieved in accordance with the invention.

The fact that the perfumes / active ingredients are together in a preparation that is separate from the basic preparation and that does not contain any other disruptive constituents, significantly increases the stability and thus shelf life.

According to the invention, the problematic mixing with high energy input and oxygen contact of the perfumes / active ingredients is avoided.

Like most active ingredients, perfumes belong to the particularly cost-intensive product components of cosmetic, dermatological or pharmaceutical preparations. Of Furthermore, many of these substances cause increased production costs and are often difficult to incorporate into the masses.

Since, according to the invention, the combination of active ingredient and / or perfume with the rest of the basic preparation takes place as late as possible before use by the consumer, namely only during application, “scattering losses” are avoided and the use of these substances can be significantly reduced.

Surprisingly, it has been shown that, on the basis of the kit according to the invention, a preparation containing perfume / active ingredient can be provided which comprises less perfume / active ingredient but nevertheless does not show any loss of effectiveness.

The particular advantage of the kit according to the invention, however, is that the kit according to the invention leads to a more economical and resource-saving use of active ingredients / perfumes and thus also contributes to reducing costs.

The viscosity range of the respective components is preferably in the usual range for cosmetic preparations in the creams category, that is to say approximately between 5000-15000 mPa.s (20 ° C.).

The openings (3) in the cannula are ideally dimensioned in such a way that the active substance preparations can be carried along via the openings with the base strand without any problems. The size of the openings can also be selected individually depending on the viscosity and any particulate constituents contained therein.

The diameter of the openings (3) can therefore be selected in particular in the range from 0.5 to 5 mm.

The system works advantageously when the preparation components are adjusted to approximately the same viscosity. For this purpose, the component to be added with perfume / active ingredient is ideally prepared for use in a highly concentrated “pre-solution”.

The entrainment of the active ingredient preparation when applying the basic preparation is known to be based on the “water jet pump” principle.

In the , , and Kits according to the invention are shown in perspective or in a side or top view for better explanation.

shows a tube neck in the upper third of a malleable container (1) . The container (1) consists for example of aluminum, plastic or a laminate.

The mouldable container comprises an opening in the front part (4) that by means of a cannula (5) is extended into the interior of the container. The opening (4) can be closed as usual with a lock. The cannula (5) has one or more openings in the side wall (3) on. First, a preparation comprising, for example, vitamin C is provided (7) . This active ingredient preparation (7) includes only one or more suitable ingredients such as water, thickener and / or lipids as well as a high proportion of vitamin C.

The remaining preparation (8th) can now be designed in any way and include customary cosmetic ingredients such as skin moisturizers, preservatives, emulsifiers, lipids and water.

Depending on the desired form of preparation, emulsions, pastes, anhydrous or water-containing preparations, gels, hydrodispersions, creams, pastes, etc., the person skilled in the art can act flexibly.

With the help of suitable thickeners, waxes or oils, any desired viscosities can be set.

The active ingredient preparation containing vitamin C. (7) will be in the field (2) placed between the container wall (6) and cannula (5) . The area (2) is shaped like a donut around the cannula.

Due to the manual pressure on the advantageously malleable container wall (6) becomes a strand of basic cosmetic preparation (8th) via the cannula (5) from the opening (4) carried out. The rich vitamin C preparation (7) is about the openings (3) stranded with discharged. When rubbed on the skin, the two preparation components ( 7th , 8th ) first mixed and the effect of the vitamin C-containing preparation is then achieved without first considering stability problems.

shows a side view of the example shown.

Via the cannula (5) the basic preparation can through the inner opening (4b) (8th) can be dispensed via an upper dispensing opening (4a). The preparation containing vitamin C. (7) is in the area (2) , formed from container wall (6) and cannula (5) , placed.

shows another embodiment of the kit according to the invention with a movable punch (10) at the bottom of the container, at the end of the container (1) , which is then advantageously made of dimensionally stable material. A separator (9) can then also be displaceable like a stamp around the pressure and application of the active ingredient preparation (7) to guarantee. A stretchable film (9) as a separating device is also conceivable. In a manner similar to that explained above, pressure is now applied to the preparation when the stamp is actuated (8th) that through the cannula (5) from the opening (4) can be output. About the opening (3) In this case, depending on the number of openings, strands of the active substance preparation are placed in the cannula (7) with issued.

When the container is squeezed out, a preparation strand of the unperfumed or active ingredient-free preparation is applied to the edge of which one or more, depending on the number of openings, strips of the perfume / active ingredient preparation are also applied.

With the help of the number and size of the openings in the cannula and with the help of the size of the area that results from the cannula length, circumference and container wall, the amount of perfume or active ingredient can be controlled individually.

shows a plan view of a further embodiment of the kit according to the invention, in which the area (2) through partitions (11) is divided into three areas. For example, three different active ingredient preparations (7a, 7b, 7c) can each be placed in the areas between the partition walls (11) be filled. The rest of the active ingredient-free preparation (8th) is then filled into the rest of the container as before. Because different active ingredient preparations are positioned in the respective three areas, it now occurs when the preparation is dispensed (8th) so that at least three different active ingredient preparation strands (7a, 7b, 7c) are attached to the basic preparation strand (8th) let spread. shows the dispensed preparation strand.

It goes without saying that there is at least one opening in the respective areas (3) in the cannula (5) available.
