Definitions
- the present invention relates to detergent tablets which have a specially designed depression with a specific geometry.
- the invention relates to moldings composed of detergents and cleaning agents and detergents and cleaning aids such as, for example, dishwasher tablets, detergent tablets, detergent tablets, bleach tablets, stain remover tablets, water softening tablets and toilet cleaning tablets.
- Detergent tablets are widely described in the prior art and are becoming increasingly popular with consumers because of their easy meterability, their low packaging complexity and their aesthetic characteristics.
- a large number of design options for such shaped bodies are known from the prior art and from everyday life, ranging from the most varied of shapes (angular, round, etc.) and colors to multi-phase shaped bodies.
- multilayer tablets (“two-phase tabs”), ring-core shaped bodies or core-shell tablets have been established in the prior art.
- European patent application 055 100 (Jeyes Group) describes, for example, toilet cleaning tablets in designs such as tray tablets, core-shell tablets and ring-core tablets. In general, this document describes several possible shapes and does not deal with special geometries in the case of the hollow tablets.
- the European patent application 481 547 (Unilever) describes "multilayer" - detergent tablets which have the shape of a ring-core tablet which has at least three layers (inner, barrier and outer layers). In this document, which does not deal with trough tablets, no statements are made regarding geometric parameters.
- Multi-phase or multi-layer detergent and cleaning agent bodies are described for example in European patent applications EP 481 792 (Unilever), EP 481 793 (Unilever) and international patent application WO97 / 03177 (Benckiser).
- Trough tablets are not widely described in the prior art, since there are special problems in their manufacture.
- the lower punch, to which the mixture to be pressed is applied, or the pressing upper punch has a bulge which produces the depression during the pressing.
- the problem often arises that the mechanical stability of the tablet is too low. So it often happens that the web that surrounds the trough breaks when the upper punch is withdrawn, or that the premix partly sticks to the shaped surface of the punch, which leads to the destruction of the tablet or to an indefinable and non-reproducible volume the hollow leads.
- tray tablets have advantages that make them particularly attractive for detergent tablets: special detergent ingredients can be pressed or poured into a prefabricated tray; however, it is also possible to pour certain substances into the trough and thus separate incompatible components.
- the aesthetic aspect is not to be neglected either, because the shape of the tray has a high level of consumer acceptance due to its "fried egg structure".
- the present invention was based on the object of providing a detergent tablet which has a depression and is nevertheless free from the disadvantages mentioned.
- both the shaped body itself and the webs which enclose the trough should be mechanically stable and also capable of being produced on modern tablet presses with high throughputs.
- the trough should also have a high level of volume fidelity in large series production.
- the invention relates to detergent and cleaning agent bodies made of compressed particulate material, in which the shaped body has a depression whose relative web width is ⁇ 0.4.
- the relative web width is a size that is independent of the geometry of the molded body and the geometry of the trough.
- the web width In the case of a rectangular molded body with a symmetrically arranged rectangular trough, the web width is constant over the entire web, in the case of a round or ellipsoidal trough the web width varies since the curvature of the trough results in an increased distance from the edge of the molded body.
- the absolute web width is the smallest distance between the edge of the trough and the edge of the molded body.
- the web width can have a different value in the case of a longitudinal section through the molded body than in the case of a cross section.
- relative web width is illustrated by FIG. 1 (longitudinal section through the molded body), in which L stands for the length of the rectangular molded body, L2 for the length of the trough, and L1 and L3 for the web widths.
- Ll and L3 are identical.
- the relative web width is the quotient of Ll and L or L3 and L.
- Figure 2 shows a cross section through the rectangular shaped body, i.e. the width B is different from the molded body length L.
- the web widths and relative web widths as well as the width of the trough result analogously to the longitudinal section. Any length dimension can be used to determine the absolute web width, since the physical unit is divided out by forming the quotient and the relative widths are therefore dimensionless.
- Detergent tablets preferred in the context of the present invention have a relative web width of less than 0.4, preferably less than 0.3 and particularly preferably less than 0.25.
- the web width can vary depending on the absolute size of the molded body. Usually, however, the relative web width is at least 0.005, preferably at least 0.01 and in particular at least 0.015. It applies here that the relative web width is chosen to be greater the smaller the shaped body itself, in order to achieve practical and safe web widths. The person skilled in the art has no problems with the selection of the web widths, so that the minimum widths mentioned are to be understood as guide values which can be varied within the scope of the present teaching.
- a relative trough depth can also be defined.
- H stands for the total height of the molded body and Hl for the height (or depth) of the trough. The quotient of Hl and H is then called the relative trough depth designated. It is preferred in the context of the present invention that the relative trough depth is ⁇ 0.5. Shaped and detergent tablets are particularly preferred in which the relative trough depth is less than 0.5, preferably less than 0.4 and in particular less than 0.35.
- Preferred molded bodies with troughs have a rectangular shape and have different relative web widths on the longitudinal and cross-section.
- the trough can be circular, elliptical or ellipsoidal or rectangular.
- rectangular shaped bodies it is also possible for rectangular shaped bodies to be produced in which the relative web widths on the longitudinal and cross-sections are identical.
- the troughs can be round, elliptical or ellipsoidal or rectangular.
- the identical relative web width in the longitudinal and cross-sections means that the absolute web widths are different due to the differences between length and width.
- the shaped bodies with a square base as a special case of a rectangle, in which the same relative widths require the same absolute widths.
- the person skilled in the art can choose both the absolute and the relative web widths identically or differently, depending on which aesthetic impression he prefers.
- the only selection criterion here is that the relative web width at the point closest to the trough at each mold body edge is ⁇ 0.4.
- the detergent shaped bodies have a circular shape.
- trough shapes are square, circular or elliptical or ellipsoidal troughs.
- the combination of the multilayer principle known from the prior art with trough-shaped bodies is particularly attractive. It is possible and preferred according to the invention to produce a detergent molded article from two or more layers which has a trough. In this way, the aesthetics can be further expressed by coloring the two layers differently and the filling of the trough having a third color.
- the trough can be orthorhombic, that is to say have the shape of a brick, but it can also, for example, be round or elliptical in plan view - as already explained.
- the shape of the trough in the longitudinal or cross section of the molded body does not have to be rectangular, as is shown in simplified form in the figure. Rather, it is preferred that the contact angle of the trough is greater than 90 °, preferably greater than 95 ° and in particular greater than 100 °.
- the trough contact angle is identified in the figure by abc or def. It is conceivable here that the trough has the shape of a triangle, but curvatures, i.e. Troughs which also have the shape of a cut-off ellipse or a semicircle in the longitudinal and / or cross-section are possible and preferred.
- detergent shaped bodies are particularly preferred in which the contour line of the trough continuously drops from the base point b or e to the center of the trough.
- the curvature can also begin directly at points b and e, so that the trough has no vertical flanks bc or de (ellipsoidal trough shape).
- the ingredients of the individual areas of the molded body the person skilled in the art has no limits.
- the trough of the shaped body is filled and in particular filled with detergent and cleaning agent ingredients.
- a rectangular tablet with an elliptical depression was produced from a pressable composition for machine dishwashing, and had the following parameters:
- Length of the ellipse 2.2 cm
- Width 2.6 cm
- Width of the ellipse 1.6 cm
- the ellipse was arranged symmetrically, resulting in absolute web widths of 0.7 cm (L1, L3) and 0.5 cm (B1, B3).
- the relative web widths are:
- the tablets could be easily produced on a rotary tablet press in quantities of over 10,000 / h. During a four-hour test run without interruption, no caking occurred on the press rams of the tablet press, nor were molded articles produced which had broken webs or other damage. If the length of the ellipse is shortened to 0.5 cm (absolute web width 1.55 cm, relative web width 0.43), mechanically unstable molded bodies are created, in which web breaks and hooks occurred on the pressing tools.
