Definitions
- the invention relates to a package consisting of a container for products and arranged on this container device for receiving additive portions.
- a particularly suitable medium for the individualization of a product is its packaging, since this forms the direct interface between consumer and product.
- a product package is designed such that the fragrance of the product contained in the package is olfaktometrisch perceptible.
- packaging is also increasingly functionalized in that fragrance-emitting means are arranged on the packaging, which release a certain fragrance into the environment of the packaging and thus assume the additional function of a room freshener.
- blister packs are common, for example in the field of drug delivery.
- individual drug dosages for example in the form of tablets, each packaged in a chamber of a blister pack.
- such a blister pack consists of a first surface element, in which a plurality of individual, usually cup-shaped, mutually separate cavities for receiving product doses are formed and a second surface element, which is connected areally with the first surface element and closes the cavities.
- the first surface element, in which the cavities are introduced consists of a plastic film piece in which the cavities are formed, for example by deep drawing.
- the second surface element occluding the cavities is made of a material that is sufficiently strong to open unintentionally avoid, however, by applying a corresponding pressure, for example by thumb pressure or tearing of the film with a fingernail, can be opened.
- a blister pack can also be designed such that the second area element closing the cavities is made stronger in such a way that the cup-shaped cavities of the first area element are opened by the applied pressure and the second area element closing the cavities remains undamaged.
- the blister pack consists of a plurality of perfume-filled chambers, the back of the blister pack being provided with an adhesive layer which can be adhered to a garment or human skin.
- the blister pack is not permanently connected to a carrier object.
- the blister pack can always be completely detached from the carrier object, such as the human skin.
- the carrier object such as the human skin.
- a blister pack may inadvertently fall off the sales package or, for criminal intent, be removed from the sales container, for example due to adhesive failure.
- the product in the cup-shaped depressions of the blister pack can not be released by destruction of the lower film, since this lower film according to the teaching of DE4239082 sticks over the entire surface on the support object.
- this lower film according to the teaching of DE4239082 sticks over the entire surface on the support object.
- fragrance-emitting substances are arranged in a chamber of the container closure, this chamber being sealed with a film which can be removed for use of the room freshener cap, so that fragrance can be released from the closure flap to the environment.
- a disadvantage of this solution is the comparatively large and thus unwieldy for the consumer form of this closure.
- the inner volume of the closure is almost completely filled with a fragrance, practically no dosing volume is available any more, so that the closure can generally not be used as a dosing device, as for example for closures of softener or floor cleaner. Due to the necessarily enlarged design compared to conventional closures, also increases the storage requirements for such equipped container, which inevitably leads to increased logistics costs.
- CA983437 discloses a container for medical applications where it is necessary to take a prescribed dose of a tablet or capsule in association with a liquid.
- a container according to CA983437 has means for receiving the individual cans on the outer wall of the container. These are depressions in the outer wall, in which the individual doses can be inserted or placed.
- the cans located in the wells are then fixed with adhesive tape in the wells. To remove a dose, the adhesive tape can then be lifted and withdrawn, so that a dose is released and can be removed from the recess of the outer wall of the container.
- This solution has the disadvantage that the production of a corresponding container is expensive and technically complicated. In addition, large areas are needed, which significantly limits the space for advertising and / or descriptive labels. This also appreciably negatively affects the overall aesthetic impression of the container.
- Another disadvantage of this solution is that no pasty or gelatinous preparations can be dosed and removed.

- Polyethylene is a collective name for polymers belonging to the polyolefins with groupings of the type
- Polyethylenes are usually prepared by polymerization of ethylene by two fundamentally different methods, the high pressure and the low pressure process.
- the resulting products are accordingly often referred to as high pressure polyethylenes and low pressure polyethylenes, respectively; they differ mainly in their degree of branching and, consequently, in their degree of crystallinity and their density. Both methods can be carried out as solution polymerization, emulsion polymerization or gas phase polymerization.
- HMW-LDPE high molecular weight
- the macromolecules of the polyethylenes from low-pressure process are largely linear and unbranched.
- These polyethylenes abbreviated to HDPE (from E high density polyethylene) have degrees of crystallinity of 60-80% and a density of about 0.94-0.965 g / cm3. They are referred to as products with high or ultra-high molar mass (about 200 000-5 000 000 g / mol or 3 000 000-6 000 000 g / mol) under the short name HD-HMW-PE or UHMW-HD-PE offered.
- medium density (MDPE) products from blends of low and high density polyethylenes are commercially available.

- Polypropylene (PP) is the name given to thermoplastic polymers of the
- the basis for the polypropylene production was the development of the process for the stereospecific polymerization of propylene in the gas phase or in suspension by Natta. This is initiated with Ziegler-Natta catalysts, but increasingly also by metallocene catalysts and leads either to highly crystalline isotactic or less crystalline syndiotactic or amorphous atactic polypropylenes.
- Polypropylene is characterized by high hardness, resilience, stiffness and heat resistance. Short-term heating of polypropylene articles is even possible up to 140 ° C. At temperatures below 0 ° C., some embrittlement of the polypropylenes occurs, which, however, can be shifted to much lower temperature ranges by copolymerization of the propylene with ethylene (EPM, EPDM). In general, the impact resistance of polypropylene can be improved by modification with elastomers. The chemical resistance is good as with all polyolefins. An improvement in the mechanical properties of the polypropylene is achieved by reinforcement with talc, chalk, wood flour or glass fibers. Polypropylenes are even more sensitive to oxidation and light than PE, which is why the addition of stabilizers (antioxidants, light stabilizers, UV absorbers) is required.
- stabilizers antioxidants, light stabilizers, UV absorbers
- Polyether is a comprehensive term in the field of macromolecular chemistry for polymers whose organic repeating units are held together by ether functionalities (COC).

Polymers with pendant ether groups, such as the cellulose ethers, starch ethers and vinyl ether polymers, are not included among the polyethers.
- the group of polyethers also includes functionalized polyethers, d. H.
- Compounds having a polyether backbone laterally attached to their backbones still carry other functional groups, e.g. As carboxy, epoxy, AIIyI or amino groups, etc. are widely used block copolymers of polyethers and polyamides (so-called polyetheramides or polyether block amides, PEBA).
- Polyamides are polymers whose basic building blocks are held together by amide bonds (-NH-CO-).

- the former are made of only a single monomer by z.
- B polycondensation of a ⁇ -aminocarboxylic acid (1) (polyamino acids) or by ring-opening polymerization of cyclic amides (lactams) (2).
- the most commonly used polyamide types consist of unbranched chains with average molecular weights of 15,000 to 50,000 g / mol. They are partially crystalline in the solid state and have degrees of crystallization of 30-60%. An exception are polyamides of building blocks with side chains or co-polyamides of very different components, which are largely amorphous. In contrast to the generally milky-opaque, semi-crystalline polyamides these are almost crystal clear.

- Polyester is the collective name for polymers whose basic building blocks are held together by ester bonds (-CO-O-). According to their chemical structure, the so-called homopolyesters can be divided into two groups, the hydroxycarboxylic acid types (AB-polyester) and the dihydroxy-dicarboxylic acid types (AA-BB-polyester). The former are made of only a single monomer by z. B. polycondensation of a ⁇ -hydroxycarboxylic acid 1 or by ring-opening polymerization of cyclic esters (lactones) 2 produced.
- polyesters are obtained in the polycondensation of trihydric or polyhydric alcohols with polyfunctional carboxylic acids.

- Purely aromatic polyesters are the polyarylates to which u. a. which include poly (4-hydroxybenzoic acid).
- unsaturated polyesters from unsaturated dicarboxylic acids which have acquired industrial significance as polyester resins, in particular as unsaturated polyester resins (UP resins).
- Polyesters are usually thermoplastics. Products based on aromatic dicarboxylic acids have pronounced material character. The purely aromatic polyarylates are characterized by high thermal stability.
- Polyurethanes are polymers in whose macromolecules the repeat units are linked by urethane groups -NH-CO-O-. Polyurethanes are generally obtained by polyaddition from dihydric or higher alcohols and isocyanates.
- polyurethanes with very different mechanical properties, which are used as components of adhesives and paints (polyurethane resins), as ionomers, as a thermoplastic material for bearing parts, rollers, tires, rollers and as more or less hard elastomers in fiber form (elastofibres, short PUE for these elastane or spandex fibers) or as polyether or polyester urethane rubber (EU or AU)
- Polyurethane foams are formed in the polyaddition, when water and / or carboxylic acids are present, because these react with the isocyanates with elimination of the uplifting and foaming carbon dioxide.
