Description

BKster packaging with multi-phase preparation and Duftabaabesvstem

The present invention relates to a blister pack and provided for the blister packaging scent delivery system in particular for deodorization and / or for scenting rooms.

In toilets often unpleasant odors occur especially in the absence of fresh air. In order to keep the toilet air fresh and eliminate the annoying odors or reduce as much as possible in addition to air fresheners

Room freshener known.

These room fresheners can be for example one with perfume or another

odor-dispensing formulation impregnated solid, which usually has a decorative or decorative design purposes or optical design. Such Raumuftufter, which is used directly on a toilet paper roll, is known from US 5,170,938. It includes two on the two end faces of one

Toilet paper roll attachable discs, from which for decoration purposes each different patterns, symbols or figures are punched out. These discs, which are also individually usable, can either be impregnated directly with a perfume formulation or they can serve as a support for a separate fragrance carrier, which in turn is impregnated with a perfume formulation. However, such a room freshener has a decreasing fragrance intensity over its duration of action and thus a decreasing scenting of the ambient air. This is a common problem of common passive fragrance dispensers, which alone allow a diffusion-related subsequent delivery of the fragrance from the fragrance-bearing material.

Other room fresheners include an apertured housing that may be filled with various air-cleaning and / or fragrance-emitting substances. So WO 2004/020004 proposes a scent delivery system, which in a

rotationally symmetrical container with crescent-like cross-sectional shape containing a variety of perfume-bearing particles. For example, the system may be suspended from a suitable location in a toilet via an attached fixture and emit fragrance there. However, it would be desirable to have a perfume dispenser that realizes repeated, simultaneous release of at least two distinct perfume formulations. Object of the invention

Object of the present invention is therefore to provide a structurally simple, inexpensive to manufacture and easy to handle fragrance delivery system of the type mentioned, which realizes a repeated, simultaneous release of at least two different fragrance preparations.

This object is achieved by a blister pack according to claim 1, and by a blister packaging using scent delivery system according to claim 12. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

The blister pack according to the invention is provided in particular for inclusion in containers for deodorizing and / or for scenting rooms on rotatably mounted paper rolls. Of course, it is also conceivable, the invention

Blister pack directly, so to use without coupling with a container or dispenser, for the deodorization and / or scenting of air.

The blister pack is substantially dimensionally stable and designed to hold flowable, active substance-containing preparations, the walls of the blister pack being configured in such a way that the active substances contained in the preparations in the

Essentially not through the walls into the environment. Furthermore, the blister pack has an opening, wherein the opening is closed with a semi-permeable membrane, which is passable in particular for the active ingredients contained in the preparations. It is thus possible for the membrane to be wetted by the liquid preparation or for liquid preparation to be present on the membrane, but the preparation does not run out of the blister packaging. Such membrane systems for the release of, for example, fragrances are known to the person skilled in the art. The blister pack according to the invention is at least partially filled with at least two mutually different preparations, wherein the preparations have a phase boundary in the state filled in the blister pack.

It is preferred that the phase boundary is visible. This can be effected for example by a different, in particular high-contrast coloring of the respective preparations.

In the case of two mutually different preparations, it is conceivable that the preparations are introduced into the blister pack in several layers relative to one another, so that several phase boundaries are formed. The layers can, for example, run in stripes like one another.

In general, it is also conceivable that more than two, in particular three different preparations are stored in the blister pack.

In order to form a phase boundary, it is particularly preferred that the mutually different preparations have a mutually different polarity and / or density.

Furthermore, it is preferable that at least one preparation contains one or more, in particular different from each other fragrance (s) and / or

Odor Removal Substance (s). Some - but not final - combinations are listed as examples in the following table:

The preparations can essentially the same permeation and / or

Have diffusion properties through the semipermeable membrane, so that a substantially similar discharge flow of active ingredients of the preparations is effected in the environment.

However, it is also conceivable that the preparations have mutually different permeation and / or diffusion properties through the semipermeable membrane, so that different discharge streams of active substances from the preparations into each other

Environment are effected. It is preferable according to a further, preferred embodiment of the invention that the blister pack and / or the receiving space of the blister pack for the preparations are annularly shaped. The blister pack according to the invention can be provided in particular for use with a container in which the blister pack can be received.

According to a preferred embodiment of the invention, the container is annular and encloses a particular annular receiving space.

Furthermore, the container advantageously comprises non-positively and / or positively acting fastening means for non-rotatable connection of the container with a paper roll and / or with the core tube of a paper roll.

The main advantage lies in the fact that a ring-shaped container can be pushed together with a paper roll on fixed holding axes of paper roll holders. Thus, a ring-shaped according to the present invention formed container, for example, together with a toilet paper roll on a fixed support axis of a toilet roll holder. Nevertheless, the container can also be used on the removable double-sided holding cores of older design. Therefore, the fragrance delivery system according to the invention can be used in particular in all known types of toilet paper roll holders.

It does not depend on the cross section of the annular receiving space. For example, the cross section may be oval, but also with straight lines and / or corners. In particular, the receiving space may be in the form of a tom. It is only essential that the container is designed in the form of a ring with a conventional axis and core roles sufficiently large-sized free space so that he freely rotatable without clamping phenomena on an axis or core role of a

Paper roll holder can be attached. Another significant advantage is that due to the rotational, attachment of the annular container to the paper roll regardless of the unwinding always a sufficient rotational movement of the container and thus reliably the desired increase in the scenting room when rolling paper is achieved. The fragrance delivery system according to the invention is characterized by a constant

Fragrance release in the rest position of the roll of paper and a particularly beneficial, because immediately acting and slowly decaying after the rotation fragrance boost when turning the paper roll. This is accomplished by wetting the entire membrane surface with viscous preparation during spinning and viscosity-induced adherence of the preparation to the membrane surface. For this purpose, the kinematic viscosity of the stored in the blister pack preparation at 40 ° C between 1, 4 and 150 mm2 / s, preferably 1, 4 and 44 mm2 / s set, the volume of the blister pack preferably filled with less than 95% of the preparation is. The kinematic viscosity is determined according to DIN EN ISO 3104.

By filling the annular blister pack with perfume-containing preparation of less than 95% is further a slight olfaktometrische distinction between the release of perfume in the rest position of the paper roll and during or after the rotation of the paper roll allows.

Furthermore, the filled with perfume, annular blister pack can be removed after use in a simple manner from the scent delivery system and replaced with a new, freshly filled blister pack.

The scent delivery system according to the invention is inexpensive to manufacture and easy to assemble and easy to handle with a simple construction. For attachment to a paper roll, the fastening means may preferably be designed so that a simple axial attachment of the annular container on a front side of a paper roll the intended rotationally fixed connection with the paper roll or with the usually from

Cardboard existing core tube of a toilet paper roll or a paper towel roll generated. In addition, this can also ensure a positive and / or positive fit in the axial direction. Furthermore, it is advantageous that the scent delivery system has a comparatively low weight, whereby when turning the paper roll only a comparatively small imbalance arises and the paper roll is not pushed or pushed out of its intended guidance. For a particularly easy and preferably concentric positioning of the annular container on a paper roll, the present invention further proposes that the container has a coaxially projecting sleeve which can be inserted axially from an end face of a paper roll into the paper roll or into the core tube of a paper roll. In this case, the sleeve can either be attached to the container as a separate component or formed integrally with the container or a part of the container.

In this case, it is furthermore particularly advantageous if the sleeve has a conical shape, so that its free end with a smaller outside diameter can be inserted particularly easily into the core tube of a paper roll. At the same time in this way a non-positive grip on paper rolls with

different core tube inner diameters can be achieved.

The adaptability to different inner diameters of paper rolls can be further improved if the sleeve has two or more at least substantially axial

Separating slits extending from the free end of the sleeve over at least a portion of its axial length, so that the free end portion of the sleeve is divided into two or more peripheral portions, which can relatively easily bend inwardly elastically.

A particularly preferred type of fastening means provides that at least one elastically outwardly resilient retaining element is provided on the sleeve. Preferably, the holding elements extend as wedge-shaped retaining webs radially outwards, which are pressed increasingly when inserted into a core tube of a paper roll inward and thus lead to a frictional attachment. Alternatively or additionally, the fastening means may also comprise hooks and / or brackets.

The container can in principle be produced in different ways, it can for example be made in one piece by an injection molding process.

According to a particularly preferred embodiment of the invention, the container consists of at least two container parts, wherein a first container part comprises a flat or curved rear wall and a detachable or non-detachably connected thereto second container part a flat or curved front wall. If the container is formed in two parts, the two container parts can be produced in a particularly simple manner by injection molding. Particularly preferably, the two container parts are connected to one another with a material bridge.

The releasable attachment of the two container parts together allows easy replacement of the blister packaging, if after the expiration of their time a

adequate scenting of the ambient air is no longer present. Under the back wall is to understand the wall of the container, which rests in the use position on the front side of a paper roll.

It is particularly advantageous if the front wall having the second container part comprises a radially inner and a radially outer side wall, wherein the side walls are preferably connected via rounded portions of the front wall.

In particular, the front side may also have a curvature, so that the second container part is formed overall like a bead. It is also advantageous if the rear wall having first container part has a web-like edge region, the be used for easy attachment to the side walls of the second container part.

If the container has a sleeve of the type described above, it is furthermore advantageous if the first container part, which comprises the at least substantially flat-shaped rear wall, is connected to the sleeve. Preferably then corresponds to the

Inner diameter of the sleeve in its adjacent to the rear wall area the

Inner diameter of the inner side wall of the second container part in her to the

Rear wall of the first container part adjacent region, so that between the sleeve and the inner side wall of the container is given a stepless transition.

A particularly advantageous and simple connection of the two container parts to each other can be achieved in that they are positively and / or non-positively fastened, preferably by means of a latching connection or snap connection to each other. Also, the two container parts can be fastened to one another via one or more threaded connections or by means of hooks and / or staples.

Advantageously, the openings can be introduced into the front wall and / or into the radially outer side wall of the annular container.

As a result, the fragrances of blister packaging reach the ambient air particularly easily and quickly, which leads to a particularly effective room scenting. The front wall is the wall of the container, which faces away from the paper roll in the position of use.

The blister pack and the receiving space are preferably configured in such a way that the side of the blister pack closed with the perfume-permeable membrane is positioned on the side facing away from the paper roll in the receiving space. Preferably, the openings are formed as slots, in particular undulating. However, they can in principle have any shapes and in particular be round, oval or drop-shaped.

According to a further preferred embodiment of the invention, the openings or the fragrance-permeable membrane of the blister pack are closed with removable closing means, in particular with a removably applied or peel-off glued-on foil. As a result, an unintended fragrance delivery before the beginning of

Intended use of the fragrance delivery system prevented. Preferably, perforated stickers can also be used as closure means, whereby the selective release of individual areas of openings is possible, so that, for example, at the beginning of the action time of the fragrance delivery system, only a few radially inner openings are released first and only after a certain time and a decrease the efficacy further openings are exposed to achieve an increased fragrance delivery and thus again a satisfactory Raumbeduftung.

According to a particularly preferred embodiment of the invention it is provided that an adjustable closure part is provided, through which the openings of the container can be opened either completely or partially or completely closed. This allows the openings even after the beginning of the use of

Scent delivery system to be closed again to extend its time of action by preventing further scent delivery, for example, if the toilet is not used for a certain period due to vacation.

It is particularly advantageous if the closure part comprises an axially rotatable or pivotally mounted on the annular container cap, which is provided with a plurality of openings which can be selectively completely or partially brought into registry with the openings of the container, wherein in at least a closure position, all openings of the container are covered by the closure areas of the cap surrounding the openings of the cap. The openings in the cap can also be arranged so that with increasing rotation of the cap, the overall degree of coverage with the openings of the container continuously increases or decreases in order to make a dosage of the fragrance delivery. In a two-part

Container design is the cap as the third part of the device according to the invention preferably hinged to the container part containing the front wall, in particular rotatably clipped. Furthermore, the invention proposes that the container consists of a transparent,

transparent or semi-transparent material is formed. In this way, the consumer the degree of filling of the container and the optical condition and the

Detect movement of fragrance carrier particles. In particular, different colors of fragrance carrier particles can also be recognized and used for the optical design of the fragrance carrier

Fragrance delivery system and / or used for distinguishing purposes in different scents. Alternatively, the container may also be completely or partially formed of opaque material and galvanized, in particular chromed, to produce a particularly high-quality metallic impression. In particular, the container and the optionally present sleeve may consist of a polymer or a polymer mixture and may advantageously be produced by injection molding. As perfume oils or fragrances, individual fragrance compounds, for example the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons, can be used in the context of the present invention. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allylcyclohexyl propionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, to the aldehydes, for example, the linear alkanals with 8-18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones such as the ionone, ° c- | somethylionon and Methylcedrylketon , the alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, the hydrocarbons mainly include the terpenes such as limonene and pinene. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures, such as those from vegetable

Sources are accessible, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are muscatel, sage, chamomile, clove, lemon balm, mint oil, cinnamon oil, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil, orange blossom oil, neroliol, orange peel oil and sandalwood oil.

The general description of the perfumes that can be used (see above) generally represents the different substance classes of fragrances. To be perceptible, a fragrance must be volatile, whereby besides the nature of the functional groups and the structure of the chemical compound, the molecular weight also plays an important role plays. For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of one of several fragrances changes

composite perfume during evaporation, wherein the odor impressions in the "top note", "middle note or body" and "base note" (end note or dry out) divided. Since odor perception is also largely due to odor intensity, the top note of a perfume does not consist solely of volatile compounds, while the base note consists largely of less volatile, i. adherent fragrances. For example, in the composition of perfumes, more volatile fragrances can be bound to certain fixatives, preventing them from evaporating too quickly. At the following

Classification of the fragrances in "more volatile" or "adherent" fragrances is therefore nothing about the olfactory impression and whether the corresponding fragrance is perceived as the head or middle note. By means of a suitable selection of said fragrances or perfume oils, the product smell can be influenced in this way for agents according to the invention both immediately upon opening the brand-new composition and the use fragrance. These fragrance impressions can of course be the same, but can also differ. For the latter odor impression, the use of adhesive odoriferous substances is advantageous, while also more volatile odoriferous substances can be used for product scenting. Adhesion-resistant fragrances which can be used in the context of the present invention are, for example, the essential oils such as angelica root aol, aniseed oil, arnica blossom oil, basilol, bay oil, bergamotol, champacell blossom oil, fir pine oil, pinecone oil, elemi oil, eucalyptus oil, fennel oil, pine oil, galbanum oil, geranium oil, ginger grass oil, Guaiac wood oil, guriuri balm oil,

Helichrysum oil, Ho oil, ginger oil, iris oil, cajeput oil, calamus oil, chamomile oil, camphor oil, kanga oil, cardamom oil, cassia oil, pine oil, copaiba balsam, coriander oil, spearmint oil, caraway oil, cumin oil, lavender oil, lemongrass oil, lime oil, tangerine oil, lemon balm oil,

Musk Grain Oil, Myrrh Oil, Clove Oil, Neroli Oil, Niaouli Oil, Olibanum Oil, Orange Oil,

Origanum oil, Palmarosa oil, Patchouli oil, Peruvian balsam oil, Petitgrain oil, Pepper oil, Peppermint oil, Pimento oil, Pine oil, Rose oil, Rosemary oil, Sandalwood oil, Celery oil, Spik oil, Star aniseed oil, Turpentine oil, Thuja oil, Thyme oil, Verbena oil, Vetiver oil, Juniper berry oil, Vermouth oil,

Wintergreen oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon oil, lemon oil, lemon oil and cypress oil.

But also the higher-boiling or solid fragrances of natural or synthetic origin can be used in the context of the present invention as adherent fragrances or fragrance mixtures, ie fragrances. These compounds include the following compounds and mixtures thereof: ambrettolide, α-amylcinnamaldehyde, anethole, anisaldehyde, anisalcohol, anisole, methyl anthranilate, acetophenone, benzylacetone, benzaldehyde, ethyl benzoate, benzophenone,

Benzyl alcohol, benzyl acetate, benzyl benzoate, benzyl formate, benzyl valerate, borneol, bornyl acetate, α-bromostyrene, n-decyl aldehyde, n-dodecyl aldehyde, eugenol, eugenol methyl ether, eucalyptol, farnesol, fenchone, fenchyl acetate, geranyl acetate, geranyl formate, heliotropin, hepticarboxylic acid methyl ester, heptaldehyde, hydroquinone dimethyl ether,

Hydroxycinnamaldehyde, hydroxycinnamyl alcohol, indole, iron, isoeugenol, isoeugenol methyl ether, isosafrole, jasmon, camphor, karvakrol, karvon, p-cresol methyl ether, coumarin, p-methoxyacetophenone, methyl n-amyl ketone, methyl anthranilate, p-methylacetophenone, methylchavikole, p-methylquinoline, Methyl β-naphthyl ketone, methyl n-nonyl acetaldehyde, methyl n-nonyl ketone, Muskon, β-naphthol ethyl ether, β-

The more volatile fragrances include in particular the lower-boiling fragrances of natural or synthetic origin, which can be used alone or in mixtures. Examples of more readily volatile fragrances are alkyl isothiocyanates (alkylene sulfate), butanedione, limonene, linalool, linayl acetate and propionate, menthol, menthone, methyl-n-heptenone, phellandrene, phenylacetaldehyde, terpinyl acetate, citral, citronellal.

The preparation stored in a blister pack may contain other active ingredients in addition to the ingredients required for scenting and deodorization. From the means, which serve exclusively the scenting, can therefore be further

Differentiate product groups which contain, in addition to the aforementioned components of the invention further preferred substances.

One of these optionally usable preferred substances are the dyes. For this purpose, all dyes are generally suitable, which are known to the skilled person as suitable for coloring plastics or as soluble in perfume oils. It is preferable to select the dye according to the fragrance used; For example, lemon fragrance particles are preferably yellow in color, while for apple or herb fragrance particles, a green color is preferred. Preferred dyes have a high storage stability and insensitivity to the other ingredients of the agents and to light.

Suitable dyes and dye mixtures are commercially available under various trade names and are offered, inter alia, by the companies BASF AG, Ludwigshafen, Bayer AG, Leverkusen, Clariant GmbH, DyStar Textile dyes GmbH & Co. Germany KG, Les Colorants Wackherr SA and Ciba Specialty Chemicals. Suitable fat-soluble dyes and dye mixtures include, for example, Solvent Blue 35, Solvent Green 7, Solvent Orange 1 (Orange au grass-W-2201), Sandoplast Blue 2B, Fat Yellow 3G, Iragon ^® Red SRE 122 Iragon ^® Green SGR 3, Solvent Yellow 33 and Solvent Yellow 16, but other dyes may be included.

In a preferred embodiment, the dye additionally has an indicator function in addition to its aesthetic effect. As a result, the consumer of the current state of consumption of the fragrance is displayed so that he receives in addition to the lack of fragrance impression, which may for example be based on a habituation effect on the part of the user, another reliable indication when the fragrance dispensing system is replaced by a new one.

Furthermore, the preparations for controlling microorganisms may contain antimicrobial active substances as further optional substance. Here one differentiates depending on Antimicrobial spectrum and mechanism of action between bacteriostats and bactericides, fungistatics and fungicides etc .. Important substances from these groups are for example Benzalkoniumchloride, Alkylarlylsulfonate, Halogenphenole and

Phenylmercuric.

In order to achieve a particularly good effectiveness of the deodorization or the scenting of rooms, it is particularly advantageous if two annular containers are provided, which are fastened to the two end faces of a paper roll, in particular a toilet paper roll.

For the purposes of the invention, in particular two fragrance mixtures have proven particularly useful. Although the positive effects according to the invention can in principle be achieved in a very good manner with any perfume mixtures, we have found that the following perfume mixtures which can preferably be used are of very good quality

Results in the scent perception in the application of the invention lead.

The preferably usable fragrance mixture A is characterized in that it

(a) more than 30 wt .-%, preferably more 40 wt .-%, in particular more than 50 wt .-% of fragrances having a clogP> 3.5, in particular> 4 and a boiling point of <250 ° C comprises ( especially Decanal),

(b) more than 5% by weight, preferably more than 10% by weight, of odoriferous substances having a clogP <2 and a boiling point <200 ° C. (in particular butyl acetate),

(C) more than 10 wt .-%, preferably more than 15 wt .-%, in particular more than 20% by weight of fragrances having a clogP> 2.5 and <3.5 and a boiling point of <200 ° C. (in particular octanal).

The percentage by weight relates in each case to the total amount of the fragrances, ie it does not include solvents which may be present, such as e.g. Dipropylene glycol or isopar (isoparaffins). The preferably usable fragrance mixture B is characterized in that it

(A) more than 20 wt .-%, preferably more than 30 wt .-%, in particular more than 40% by weight of fragrances having a clogP> 3.5, in particular> 4 and a boiling point of <250 ° C. (in particular 2-methyl undecanal, isobornyl acetate or nopyl acetate)

(B) more than 10 wt .-%, preferably more than 15 wt .-%, in particular more than 20% by weight of fragrances having a clogP <3 and a boiling point of <250 ° C (in particular Borneol or eg also Dihydromyrcenol with a clogP of 3.03). The wt .-% statement in turn refers to the total amount of the fragrances, so does not include possibly contained solvents such as dipropylene glycol or isopar (isoparaffins). The ClogP value is now also well known to the person skilled in the art from the patent literature. It is due to the octanol / water partition coefficient. The logP value of numerous fragrances is documented; For example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc., (Daylight CIS), Irvine, California, contains numerous logP values, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP" program, which is also available from Daylight CIS. This program also lists the experimental logP values if they are available in the Pomona92 database. The "calculated logP" (this is the ClogP value) is determined by the Harsch and Leo fragment approach (see A. Leo, Comprehensive Medicinal Chemistry, Vol. 4, C. Harsch, PG Sammens, JB Taylor and CA Ransden, Eds., P. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approximation is based on the chemical structure of each of the perfume ingredients and takes into account the numbers and types of atoms that

Atomic bonding ability and chemical bonding. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used in the context of this invention instead of the experimental logP values in the selection of perfume ingredients which are advantageously used in the present invention. If experimental logP is available, it is possible to use the experimental logP value instead of the ClogP value.

Preferably, the fragrance delivery systems according to the invention for the scenting of

Bathrooms or toilets used. However, it can also be used on kitchen rolls or household paper rolls for scenting a kitchen space or other

Working space serve, in which such a paper roll is used.

Further advantages and features of the invention will become apparent from the following

Fig.1 shows the annular container 3 in the open position. The container 3 is designed in two parts, wherein the first container part 9 comprises a rear wall 10 from which a coaxially projecting sleeve 17 extends vertically away from the container part 9. About the elastically deformable material bridge 13 is on the first container part 9, a second

Container part 12 is formed, which includes the front wall 6 of the container 6. By pivoting the second container part 12 about the material bridge 13, the container 3 can be brought into its closed position, wherein the first container part 9 and the second container part 12 respectively latching 19,20 are provided, the first and second container part 9,12 in the closed position releasably fix.

In the closed position of the first and second container part 9,12 an annular receiving space 4 (not shown in Fig. 1) is formed in the container, in which a

corresponding, filled with perfume blister pack 1 1 can be used. This will be explained in more detail in the following section.

On the coaxially projecting sleeve 17 fastening means 18 are arranged in the form of spring tabs which allow a rotational attachment of the container 3 to a paper roll 2 and / or a core tube of a paper roll. Rotary attachment means that the attachment is configured such that upon rotation of the paper roll 2 - for example, when rolling paper - the container 3 is rotated with. The skilled person will adjust the spring forces of the spring tabs 18 accordingly.

The sleeve 17 and the fastening elements 18 are designed such that they can be inserted axially into a paper roll 2 and / or into a core tube of a paper roll 2.

FIG. 2 shows the container 3 known from FIG. 1 in a plan view. It can be seen that the front wall 6 of the container 3 is provided with openings 7, which allow a slight release of perfume into the environment. In the closed and filled with a blister 1 1 state of the container 3, the container 3 and the blister pack 1 1 is formed in such a way that the seen with a perfume-permeable membrane 15 side of the blister 1 1 positioned on the front wall 6 of the container 3 is.

The first and second housing parts 9, 12 form a closed state

Receiving space 4 for a corresponding blister pack 1 1 off. This can be clearly seen from Fig. 3, in which the opened container 3 is shown in a perspective view. It can be seen from the right-hand illustration that the first and second housing parts 9, 12 each define a shell-like space 4a, 4b. By closing the container 3 by pivoting the housing parts 9, 12 in the closed position, the annular receiving space 4 is formed for the filled with perfume blister pack 1 1. The blister pack 1 1 and the container 3 are formed so that the

Blister 1 1 in the closed position of the container 3 is rotated in a rotational movement of the container 3 about its axis of rotation defined by the sleeve 17. Thus, it is ensured that the viscous preparation when rotating the paper roll and thus the container 3 wets the perfume-permeable membrane 15 as possible over its entire wettable surface.
