Definitions
- Dispenser bottle for liquid detergents consisting of at least two partial compositions
- the invention relates to a dispenser bottle for a liquid water-containing detergent composition, which consists of at least two subcomponents held separately from one another, with at least two receptacles for partial compositions which can be stored separately from one another.
- drug fluids which are to be stored separately or must. These drug fluids should meet shortly before or during application to the application area, such as a floor, the surface of a toilet bowl, etc., meet. Examples of these are chlorine-containing bleaching, cleaning, descaling and disinfecting agents (for example WO 98/21308 A2). Active fluids of the type in question are also applied, for example, to surfaces in the bathroom or in other hygienically sensitive areas.
- Active fluids are stored in different receptacles, in particular when they are not together stable in storage. But other reasons for a separate storage of active fluids, which are to be applied together, are known, for example, different colors that should communicate different functions of the active fluids, different light sensitivities etc ..
- the dispenser bottle for at least two different, non-storage-stable active fluid from which the invention is based has a two separate chambers, which form the receptacles, having bottle at the top with is provided immediately adjacent outlets for the drug fluids in the two receptacles.
- a receptacle In a receptacle is a first aqueous solution and in the second receptacle, a second aqueous solution.
- concentration of the components in the two aqueous solutions is chosen so that, if a certain Amount of the first aqueous solution is mixed with a certain amount of the second aqueous solution, the desired in this prior art acidic bleaching solution is the result.
- the dispenser bottle of the prior art described above which forms the starting point, has a pump device which can be placed on the outlets of the two receptacles of the dispenser bottle.
- the active fluids are brought together and expelled in a common spray from an ejection nozzle, so the active fluids are mixed together before they leave the ejection nozzle.
- a similar dispenser bottle in which a cross contamination between the two receptacles can be largely safely avoided, is also known (WO 91/04923 AI).
- pump spray device is not provided, but the outlets are simply open and provided with spouts and can be closed by means of a cap.
- this dispenser bottle is not agreed.
- a dispenser bottle for a drug fluid with a receptacle made of flexible plastic and a discharge nozzle is known (EP 0 911 616 B 1), wherein for optimum application of the active fluid in the toilet bowl, in particular under its inner edge, the ejection nozzle as angled Metering tube is executed.
- the ejection nozzle as angled Metering tube is executed.
- detergents in liquid form especially if they contain water, it may due to chemical incompatibility of the individual ingredients to negative interactions of these ingredients with each other and to decrease their activity and thus decrease the washing performance of the agent altogether, even if it is stored only relatively short becomes.
- This decrease in activity relates in principle to all detergent ingredients which carry out chemical reactions in the washing process in order to contribute to the washing result, in particular bleaches, although enzymes, surfactant or sequestering ingredients which are responsible for solution processes or complexing steps, especially in the presence of said chemically reactive ingredients in aqueous systems are not unlimited shelf life.
- a possible solution is, for example, the fact that the reactivity of the chemically active ingredients is not the same at all pH values, so that by appropriately adjusting the pH of the agent, the damaging effect of an ingredient or its decomposition reaction can be minimized.
- a difficulty then arises in that the minimum of the reactivity of the chemically active ingredients is not usually at the same pH, and therefore stabilization via the pH is not normally possible for all ingredients at the same time.
- a liquid detergent known which consists of at least two liquid partial compositions, wherein the active fluids are stored separately in a container having at least two chambers (receptacles) and at least one of which has an imine or oxaziridine bleach activator and at least one other alkalizing agent, at least one of the partial compositions containing a peroxygen bleach and each sub-composition has a pH that leads to stability.
- the alkalizing agent increases the pH of the final composition so that bleach and bleach activator effectively react with each other.
- European Patent EP 0 807 156 B1 discloses a dispenser with two chambers, the first chamber of which contains an aqueous composition of hydrogen peroxide or an organic peracid having a pH above 2 and below 7 and whose second chamber contains an acid component and from which the contents are dispensed together or sequentially onto a surface such that the resulting mixture has a pH of at most 2.
- German patent application DE 100 24 251 A1 proposes a bleaching agent which comprises in a first component an aqueous 1 to 40% by weight aqueous imidoperoxycarboxylic acid dispersion and in a second component a substance mixture activating the first component, correspondingly separately Keep the dual-chamber bottle and mix the two components only during use.
- the second component also referred to as pH-regulating buffer solution in this document, consists of an aqueous solution of sodium bicarbonate and sodium carbonate which has been thickened with the aid of methylcellulose.
- a dispenser bottle for a liquid detergent composition which consists of at least two separately held subcomponents (drug fluids) to provide at least two receptacles for the at least two subcomponents, which can be produced inexpensively and easily handled by an operator while allowing the at least two sub-compositions to be applied separately from one another but in an application field.
- a dispenser bottle for a liquid hydrous detergent composition which consists of at least two, preferably exactly two separately held subcomponents, the dispenser bottle a first receptacle (1) and at least one, preferably just a second receptacle (2 ), and the first receptacle (1) comprises a first part composition and the second receptacle (2) comprises a second part composition, wherein the two receptacles (1, 2) are either made separately and connected or integral with each other, the receptacles (1 , 2) each have an outlet (3, 4) for the partial composition and the outlets (3, 4) are arranged adjacent to one another in such a way that the two partial compositions can be applied in a common application field (5) of an application area, wherein white Furthermore, the outlets (3, 4) are each provided with at least one, preferably with exactly one ejection nozzle (6, 7), so that the partial compositions are mixed together only after leaving the ejection nozzles (6, 7), the dispenser bottle being
- Another object of the invention is the use of such a dispenser bottle for the application of detergents.
- the receptacles are preferably designed as compressible containers. By squeezing the receptacle by hand of an operator so the necessary internal pressure in the receptacles generated to expel the drug fluids from the separately provided ejection nozzles.
- the required pressure can also be generated by gravity, if the product delivery is not horizontally or not up against gravity, but down discharged, such as when applying textile treatment agents on contaminated fabrics for stain removal or when entering detergents in the washing machine or their bleach dispenser.
- the active fluids thus mix only after leaving the ejection nozzles in the application field. This results in the application of the two drug fluids, the desired product to be applied, especially the detergent, which unfolds the desired effect in the application field.
- the claimed dispenser bottle achieved the result described above with a structurally very simple and easy to handle solution, in particular waiving a Pumpsprühvomchtung.
- the claimed dispenser bottle is ideal for use as a mass product.
- active fluids are to be understood as meaning all liquid and other flowable media, from low-viscosity to viscous to gelatinous to pasty substances. It is also possible to apply powdery and particulate active ingredients such as granules to the dispenser bottle according to the invention.
- the viscosity of the active substance fluids or flowability of the active ingredients for the particular application of interest on the other hand, and in a special way, the thixotropy of the active fluids is important (for explaining the concept of thixotropy, the phenomenon that certain drug fluids are exposed to mechanical Liquefy forces after completion of the mechanical stress, but if necessary with a considerable time delay again solidify, so have a dependent on the action of mechanical forces viscosity, see R ⁇ MPP LEXIKON chemistry, 10th edition, Georg Thieme Verlag, Stuttgart, 1999, Volume 6 , Page 4533).
- the cross-sectional constrictions are arranged on the mutually facing sides of the nozzle channels in such a way that the emerging under pressure drug fluids have a mutually directed swirl.
- the application field of the application area can be located.
- This embodiment with the cross-sectional constrictions is of particular importance, in particular when the active substance fluids are essentially the same type of thixotropic active substance fluids.
- the swirl effect is also caused when the openings of the nozzle channels of the Au adopteddüsen are chamfered against each other, that is, the opening planes of the nozzle channels are at an angle to each other, wherein the longitudinal axis of the nozzle channel inner portion of the wall of the ejection nozzle is longer than the outside to the longitudinal axis of the nozzle channel lying section of the wall.
