Abstract

For a container (1) with a reservoir (2) to collect a product (3) and a dispensing device (4), which is equipped with an opening (5) to dispense a flowable agent, particularly a powdery or granular product (3) dissolved and/or dispersed in a liquid (8), wherein said dispensing device is connected to the reservoir (2), a device (7) with passages (10) is used to hold back excessively large particles of the product (3), so that wholly undissolved product (3) and/or excessively large particles and/or poorly dispersed particles cannot reach the opening (5) of the dispensing device (4) and thereby cannot block the opening (5). To achieve secure protection of the opening against a blockage, it is proposed that the diameter (11) or the minimum width (12) of the passages (10) is from 0.5mm to 5mm and is less than or equal to the diameter (13) or the minimum width of the opening (5) ( Fig. 7 ).

Description

  The object of the present invention is to dispense the flowable contents in a container for collecting, mixing, dissolving and / or dispersing the product, and in an apparatus which prevents the opening of the dispensing device attached to the container from becoming clogged. It is about.

  It is known that lumps can form when a powder is dissolved or dispersed in a liquid. If the opening is relatively narrow, particles of undissolved powder and / or poorly dispersed powder particles in the liquid can clog the dispensing device. Depending on the application, a controlled distribution from the opening is desired, so an opening with a small cross-sectional area is used to prevent a distribution that cannot be controlled.

  The problem of mass formation during the mixing process can occur not only when the powder material is dissolved and / or dispersed in a liquid. It can also occur when the granular material is dissolved and / or dispersed in the liquid, when the two liquids are mixed, or when the pasty mass is mixed with the liquid. Inhomogeneities can occur in inhomogeneous flowable masses mixed with other flowable masses, and such heterogeneities are not dissolved or well because of their high viscosity. Narrow openings can be plugged as well as undispersed solid particles.

  The problem of lump formation is particularly common in hair compositions, such as hair bleaching compositions, made by mixing a liquid with powdered material and / or granular material and / or pasty material. Such compositions generally comprise a bleach activator in the form of a powder, granule or paste, which is mixed with a hydrogen peroxide containing formulation. The bleach activator contains at least one solid buffer with at least one persulfate, examples include but are not limited to sodium silicate or sodium metasilicate. These main particles generally have a size of about 100 micrometers. Immediately after mixing, only a small amount of the bleach activator dissolves and at the same time, most is dispersed in the hydrogen peroxide formulation. Undissolved persulfate and solid buffer can easily agglomerate together into a mass and close the opening. The combination of large particles that are not easily dissolved and the need for restrained dispensing using openings that have a small cross-sectional area to prevent unrestrained dispensing is the potential for clogging of the openings for such hair compositions. To be significant. In addition, a second problem can occur with hair bleaching compositions. The pH of the mixed product containing hydrogen peroxide is generally at least 8, more preferably at least 9, and even more preferably 10-11. Without wishing to be bound by theory, this elevated pH appears to promote the decomposition of hydrogen peroxide. One result of such accelerated hydrogen peroxide decomposition is that the mixed highlight composition releases a large amount of gas in a relatively short period of time. The combination of a mass that can plug a narrow opening and the rapid generation of gas by the product can lead to an increase in pressure in the container. This clogging is removed when the pressure in the container exceeds a critical value, whereby the mass is released from a narrow opening. This makes it dangerous for the container to handle such a hair composition.

  German Patent Publication No. 7639177 and German Patent Publication No. 29917054 (U1) disclose a sieve-like device and a spring ball type device for retaining particles in a baby bottle with a pacifier for infant formula. doing. Infant formula is made by dissolving fine, small particle size, soluble powdered milk with warm water. WO 98/16438 discloses a fine grid for retaining an insoluble detergent composition premixed with water prior to application to the fiber.

  These documents disclose a container for collecting a product having a dispensing device connected to a reservoir, the dispensing device being a powder or particulate to be dissolved in a flowable drug, in particular a liquid. Having an opening for dispensing the product, a connection between the dispensing device and the container, and a device for catching overly large particles or undissolved product so that the opening of the dispensing device cannot be clogged. The device is secured in position between the reservoir and the dispensing device using a mounting, which allows enough small particles and / or at least some dissolved product to pass to the opening. It has many passages to do so.

  Known containers are disadvantageous because the diameter of the passage is significantly larger or significantly smaller than the opening to be protected. With these approaches, the openings cannot reliably prevent clogging when used in hair compositions such as hair bleaching compositions, which are made by mixing together liquid and powder / granular / paste-like materials. Dispersed agglomerates can be mixed by passing through large passages in the device and clogging the openings, or clogging narrow passages and preventing product distribution from the openings, or allowing particles to remain in the device. The nature of the composition is changed from what is desired.

  The object of the present invention is therefore to prevent clogging of the opening of a container of the above-mentioned type while allowing the composition to continue to be dispensed in a reliable manner.

  This object is achieved by the features of claim 1. Accordingly, the diameter or minimum width of the passage is less than or equal to the diameter or minimum width of the opening.

  The provided container is made from a mixture of liquid and powder / granular / paste-like material, and when used in hair compositions such as a hair bleaching composition, the opening is reliably prevented from clogging. This is advantageous because it allows for further distribution. Particles and clumps are retained from reaching the opening by a device that can close the opening due to its size, but well-mixed particles dispersed in the liquid pass through, Can be distributed. If the diameter of the particle or mass is larger than the minimum width of the passage, the particle or mass is retained at that location. Since there are many passages in the device, it is very rare for all of these passages to close. The passageway is large enough to allow well-dispersed particles to pass through and be dispensed from the opening. This makes the container suitable for handling chemical solutions such as those found in hair bleaching compositions. The diameter or minimum width of the passage is about 0.5 mm to 5.0 mm, preferably about 1.0 mm to 4.0 mm, more preferably about 1.2 mm to 3.5 mm, and even more preferably about 2.0-3.0 mm. In a preferred embodiment, the device comprises a number of passages, typically about 3 to 150, more preferably about 5 to 100, even more preferably about 10 to 75, most preferably About 10-40. The device has at least 80%, preferably at least 90%, more preferably at least 95%, and most preferably at least 99% of the many passages from about 0.5 mm to 5.0 mm, preferably from about 1.0 mm to It has a diameter or minimum width of 4.0 mm, more preferably about 1.2 mm to 3.5 mm. In a particularly preferred embodiment, the device comprises 10-40 passages, 99% of which have a diameter or minimum width of about 1.2 mm to 3.5 mm. The passages may or may not have the same shape and size. Preferably, the passage is of a substantially uniform shape, more preferably a substantially circular and / or elliptical / slot shape. In a particularly preferred embodiment, the device comprises two types of passages, circular and slot shaped. The passages may also be distributed randomly or in a pattern. Preferably, the slot-shaped passages (if any) are distributed at the outer edge of the device. In another embodiment, slot-shaped passages are distributed at the outer edge of the device, and circular passages are distributed in the central region formed by the slot-shaped passages. The device may have a portion without a passage, which is preferably located approximately in the center of the device. The device itself may be of any shape, but is preferably substantially flat or upright or inverted arched. The depth of the device is preferably constant, preferably about 0.1 mm to 10 mm, more preferably about 0.5 mm to 5.0 mm, and most preferably 0.5 mm to 2 mm. Advantageous embodiments of the proposed container are described in claims 2-10.

  A spout (Claim 2) that can be attached or screwed to the container is suitable as a dispensing device, and this spout can be used to apply hair cosmetics in the correct position. In particular, colorants can be applied at the hairline. Alternatively, the hair composition can be accurately loaded into the applicator, which can then be used to apply the composition to the hair or several selected hairs.

  If the device is mounted at the connection between the container and the mounting ring of the dispensing device, as in claim 3, the device functions effectively, stirring and dissolving / dispersing the liquid. In order to support this process, a maximum space is provided in the container for the product to be dissolved / dispersed and for the liquid to dissolve / disperse the product.

  According to claim 4, if the peripheral edge of the device is fixed between the mounting ring of the dispensing device and the upper end of the neck of the container, the device is installed at the front of the container and then dispensed By fixing in place via the arrangement of the device, the device can be easily inserted into the container.

  The reservoir of the container is suitable for collecting products for coloring or bleaching hair in an advantageous manner. By doing so, the product can be provided in the container in the form of a powder, a granular material or a pasty mass to be dissolved / dispersed in a liquid, in particular a hydrogen peroxide solution, in the container.

  According to claim 5, certain advantages are obtained if there is no passage in the center, preferably circular, of the device. In this way, the closed center protects the opening from powder, granular material or cream to be dissolved / dispersed in the liquid while shaking the container to facilitate mixing. Without wishing to be bound by theory, it is believed that providing a closed center can prevent the powder / granular / glue material from clogging within the opening during the shaking process. If there is a round container neck, a rotationally symmetric dispensing device or a circular device for retaining particles, the closed center of the device makes it possible to protect the opening in a reliable manner.

  It is advantageous if the device is provided with a recess in a known manner in order to increase the passage surface and provide less outflow resistance after the components have been mixed (claim 6). In view of space, it is beneficial if this recess extends upward to the reservoir, as is known in the art. In order to prevent the recess from extending too far into the reservoir, it is advantageous according to claim 7 if the recess forms a platform connected to the edge of the device by a peripheral and annular connection region. According to experimental results, it may be advantageous if, in some cases, a circular passage with a specific diameter and a slot-shaped passage with a specific length and width are recessed in the device (claim 8). ). If only slot-shaped passages are provided on the peripheral side (claim 9), small particles moving slightly parallel to the peripheral side can better pass through the passage.

  The reservoir 2 is used to collect the product 3 in the container 1 (FIGS. 1 and 2). The dispensing device 4 connected to the reservoir 2 has an opening 5 for dispensing a flowable medicament, in particular a powder or granular product 3 to be dissolved / dispersed in the liquid 8. The connection 6 between the dispensing device 4 and the container 1 is designed as a plug connection with a snap cam 15. The dispensing device 4 is a spout 14 that can be attached to the container 1.

  A plate-type device 7 inserted in the dispensing device 4 is used to retain excessively large particles and / or lumps, so that they do not reach the opening 5 of the dispensing device 4 and clog the opening 5. But still well dispersed particles can pass through (FIGS. 3-6). The device 7 is secured in a position between the reservoir 2 and the dispensing device 4 using a mounting 9 and has a number of passages 10 that allow the lump-free mixed product 3 to pass to the opening 5. . Many passages are from about 3 to about 150, more preferably from about 5 to about 100, and even more preferably from about 10 to about 75. The device 7 can be attached to the dispensing device 4 in the region of the connection 6 between the container 1 and the mounting ring 16. In the exemplary embodiment of FIGS. 3 and 4, the device 7 is attached to the attachment ring 16 at the edge side connection region 23. In the exemplary embodiment of FIGS. 5 and 6, the device 7 is a container neck designed specifically for this purpose before the dispensing device 4 is screwed to the container 1 with a threaded connection 25. 18 is installed. After the dispensing device 4 is screwed in place, the peripheral connection area 23 of the device 7 is fixed between the mounting ring 16 and the upper end 17 of the container neck 18.

  In the exemplary embodiment of FIG. 7, the edge side connection region 23 of the circular device 7 is fixed to the region of the mounting base 9 of the distribution device 4. What is common in all exemplary embodiments is that the opening 5 of the dispensing device 4 designed as a spout 14 is used for the excessively large particles of the product 3 to be dissolved / dispersed in the liquid 8 and / or In order to allow well-dispersed particles to pass through the opening (FIG. 7) while ensuring protection from the mass, the diameter 11 or minimum width 12 of the passage 10 is the diameter 13 or maximum of the opening 5. It is less than a narrow width (FIGS. 8-19). In the exemplary embodiment of FIG. 7, the peroxide solution has entered reservoir 2 as liquid 8, where particulate product 3 that is part of the persulfate decolorizing composition is dispersed within liquid 2. To be added. Shortly after product 3 is added, a portion of product 3 is better dispersed than the rest of product 3. Areas that are not well dispersed and form lumps and can clog the openings 5 cannot pass through the passage 10. Therefore, these lumps cannot clog the opening 5. If the powder mass is not well dispersed after mixing the powder product and the solution is to be dispensed through the opening 5, the liquid 8 and the well-dispersed product 3 are connected to the device 7 and the opening. It is possible to pass through the part 5 and prevent clogging of the opening 5 by only the large particles and their clumps being properly retained by the device 7.

  If the central part 19 of the device 7 is designed without a passage 10 (FIGS. 8-11, 14-19), the possibility of clogging the opening 5 during the shaking of the particles in the center of the reservoir 2 is reduced. While not wishing to be bound by theory, it is believed that the act of shaking leads to compaction of the powder particulates in the spout 14 and creates a closure that can prevent distribution from the opening. The device 7 designed so that there is no passage 10 in the central part 19 reduces the probability that the fine powder will be consolidated in the spout 14. The recess 20 of the device 7 allows a better distribution of the liquid 8 from the spout 14 because it enlarges the surface area of the device 7 and allows more passages 10 to be present in the device 7.

  Unlike the flat design of the device 7 (FIGS. 3, 5, 7, 12 and 13), the device 7 is designed as an arch and is connected to the edge of the device 7 via the peripheral side 22 and the annular connection area 23. Platform (21) may be formed (FIGS. 8-11, 16-19), or a dome may be formed in the center (FIGS. 14 and 15). Such an arch or dome design may be oriented to extend upwards towards the opening 5 or more preferably downwards towards the reservoir 2. The circular passage 10 with a specific diameter 11 and the slot-shaped passage 10 with a specific length 24 and width 12 may be recessed in the device 7. In some exemplary embodiments (FIGS. 9, 10, 11, and 16-19), only a slot-shaped passage 10 is provided on one peripheral side 22 for improved dispensing of the liquid 8. Resulting in a lower flow resistance of the device 7. In general, the slot-shaped passage 10 is advantageous in that it provides a larger passage area through which only small particles pass and the liquid 8 is distributed.
