CZ9038U1 - Device for dosing liquid or pasty detergent into lavatory bowl - Google Patents

Description

The invention relates to a device for dispensing a liquid or paste detergent into a toilet bowl, which consists of a container with the liquid or paste detergent suspended from a hanger in a toilet bowl below its edge and having at least one opening at the top of its front wall and at least one pass at the top of its rear wall.

BACKGROUND OF THE INVENTION

For the automatic cleaning of toilet bowls, it is known that the detergent in solid form is deposited in a cage at the inner edge of the toilet bowl. During each flushing process a part of the active substance is released into the flushing water and flows through the toilet bowl together with the water. Part of the released active substance remains in the siphon and provides cleaning also there.

Detergents are used which can be formed into shape-stable, slow-dissolving blocks and have sufficient solubility to allow sufficient active substances to be transferred to the flushing water during the short flushing phase. Importantly, the active substance block remains unchanged after the flushing process, apart from the dissolution of its small part.

An example of such a detergent composition is described in DE 34 24 317 A1. The detergent composition contains anionic anionic surfactants, perfume, cellulose powder, flushing regulators, inorganic salts, complexing agents, lime-dissolving acids, antimicrobial agents, plasticizers, and other conventional ingredients.

Disposable detergent bodies for toilet bowls are also known which must be replaced after the active ingredient block has completely dissolved. Also more ecologically advantageous are the refillable detergent articles for toilet bowls, two of which are described in DE 80 01 994 U1 and DE 34 23 758 A1. On the one hand, there is the advantage of multiple usability of the detergent body in the toilet bowl, but on the other hand there is also the considerable disadvantage that the active ingredient block and in some cases the actual reservoir must be in contact with the hands when refilling. This unpleasant and, in some sense, unhygienic requirement often discourages consumers from using the detergent container in the toilet bowl again. The consumer then prefers to use a new, already filled container with the detergent body inserted. Another disadvantage of this known solution is that there is usually no possibility of inserting a new detergent body into the reservoir at any time. Indeed, replenishment is only possible when the previous detergent has been completely consumed.

These disadvantages are not present in the toilet bowl detergent body of DE 36 39 686 A1. In this embodiment, the detergent body can be replaced without manual contact, as a filling funnel is formed therein. In addition, replenishment is possible at any time, because granulate is used instead of a larger active substance block.

The major disadvantage of solid form preparations is the high technical costs and energy consumption of the production. Compact pieces of active substance are produced by casting or extrusion. Similarly high costs are incurred in the production of granulates. Since the individual components of the fragrance and cleaning compositions are initially available in liquid or paste form in the preparation of the formulation, the cost of manufacturing the formulation could be reduced if the liquid or paste form of the formulation were also chosen. Such a liquid or paste would have multiple advantages. Even in case of partial emptying of the reservoir in the toilet bowl, the active ingredient preparation could be filled or filled without problems. Unlike lump or granular products, production would be simpler and more economical. For contactless replenishment from the storage bottle, in contrast to the detergent body for a toilet bowl according to DE

-1 CZ 9038 Ul

No. 39,686 A1, no additional measures, such as a filling funnel, were necessary. A simple filling opening would be sufficient.

However, many unsolved problems have hindered the use of liquid or pasty preparations for deodorants and toilet bowl bodies. Known detergent bodies or reservoirs for toilet bowls are not applicable to pastes or liquids. In particular, after the flushing process, the paste or liquid should not spill or drip from the reservoir spontaneously. In addition, only a defined dose of liquid or paste should be dispensed in each flushing process. This dispensed dose of the active ingredient preparation should be the same for each flushing process. The residue that remains in the toilet bowl should maintain the same initial concentration and should not be diluted with previous flushing processes. At the end of the flushing process, the partially emptied cistern in the toilet bowl should not be filled with water to prevent the concentration in the top layer and dilution of the concentrate from being reduced, thus avoiding uncontrolled release of the active substance during the subsequent flushing process.

It is already known to dispense a disposable dispensing device for dispensing a fragrance and / or cleaning agent into a toilet bowl as described in DE 34 19 169 A1. The tubular, open-ended reservoir fixed on both sides of the toilet bowl by means of conventional clamps has a capillary-active active dispensing device, for example fine non-woven plastic or spongy membrane materials. Around the flushing water flow, the active substances which are available in liquid form are taken from the porous dosing medium and distributed in the toilet bowl. However, the flushing water entering the container does not completely drain from the container, so that as a result of continued dilution relatively large amounts of active substances are released at the beginning and, in further flushing processes, less active substances. Uneven release of active substances represents a significant disadvantage of this solution.

Another known solution of a detergent body or container for a toilet bowl is described in CZ-3794-97 A3. According to this solution, at least the portion in the use position of the lower wall area limiting the filling space for the active ingredient preparation is permeable to aqueous liquids with viscosities up to a maximum of 3000 mPas, but not for a surfactant containing, especially thixotropic pastes with viscosities above 3000 mPas, preferably viscosities above 30,000 mPas, the inlet opening and the outlet opening being arranged at the top of the detergent body. The permeable wall is arranged in the inner space of the reservoir so that the partially permeable wall and the outer wall create additional space in addition to the filling space. The fine, partially permeable openings are therefore provided inside the toilet bowl detergent body and are thus protected from damage. For the effluent-enriched excess water, the partially permeable wall in the lower region is provided with an outlet opening. The lower, paste-impermeable reservoir wall prevents the paste-like active substance from dripping in between the flushing processes. In the flushing process, the flushing water penetrates through the inlet opening in the above-treated area and releases a portion of the active substance on the paste surface through the outlet opening from the reservoir so that the active substance is distributed in the toilet bowl. The boundary between said lower and upper region, which is defined by the lower edge of the inlet and outlet openings for flushing water in the reservoir wall, is at the same time the boundary of filling with the liquid or pasty preparation of the active substances. In addition, the inlet and outlet openings in the upper region serve to dispense fragrance components between the individual flushing processes. With a partially emptied toilet bowl detergent, the area above the paste would be filled with flushing water, which would gradually dilute the paste, leading to uncontrolled and uneven release of the active ingredient in the subsequent flushing process. This undesirable effect is prevented by the partial permeability of the inner wall and the outlet opening. The remainder of the flushing water that remains in the toilet bowl after the flushing process in the detergent body flows through the inner wall and through the outlet opening downward into the toilet bowl.

The main disadvantage of the described solution is, in particular, its complexity and thus also the cost of manufacturing the reservoir, which requires the use of very complex injection molds. Another serious drawback is also the two-part design of the reservoir, which, on the one hand, allows cleaning of the additional space under the semi-permeable wall, although this cleaning is very difficult and requires

-2GB 9038 U1 Using tools, but there is a risk of losing one of the reservoir parts. In addition, the proper functioning of the reservoir is ensured only at a precisely defined viscosity of the detergent, which limits the applicability of this solution. If it is considered that the viscosity of the detergent material inevitably varies with time, it is clear that the apparatus described is no longer operable after a long period of inactivity.

SUMMARY OF THE INVENTION The object of the present invention is to provide a design of a device for dispensing a liquid or paste detergent into a toilet bowl that is substantially simpler compared to known designs and yet allows a defined dispensing of the liquid or paste detergent into a toilet bowl. Another task of the technical solution is to enable easy cleaning of the reservoir without the use of tools and also to eliminate the loss of individual parts of the device. Finally, another further object of the present invention is to easily fill or refill the container and to secure the storage bottle against spontaneous opening of the closure or opening by children.

The essence of the technical solution

The aforesaid drawbacks of the known devices of this kind are largely overcome and the object is solved by a device for dispensing a liquid or paste detergent into a toilet bowl, which consists of a reservoir with this liquid or paste detergent which is suspended from the hinge in provided with at least one opening in the upper part of its front wall and at least one passage in the upper part of its rear wall, according to this technical solution, characterized in that the reservoir consists of a front part and a rear part connected to each other by at least one lower yoke and at least one of the apertures in the front wall of the front of the reservoir in shape and size corresponds to the filling spout of the storage vial.

The described simple solution allows for easy opening and cleaning of the reservoir, while also avoiding the loss of any part of the reservoir. The described design of openings in the front wall of the front part of the reservoir then allows easy and clean filling of the reservoir from the storage bottle.

Preferably, a hinge bracket extends from the center of the upper side of the front wall of the front of the reservoir in the plane of the front wall.

This construction ensures that the container is suspended in the toilet bowl in the desired position and, in particular, that the container will be suspended substantially concealed under the widened edge of the toilet bowl.

Furthermore, it is advantageous if the front part and the rear part of the reservoir are releasably connected to each other in the closed state of the reservoir by at least one connecting pin which is arranged in the upper part of the front part and the rear part of the reservoir.

These connecting pins, which may be designed as posts extending from the walls, front and rear of the receptacle, snap into each other and fix the receptacle in the closed state. On the other hand, if necessary, the reservoir can be easily opened.

In addition, it is advantageous if at least one additional passageway is formed in the rear wall of the rear part of the reservoir.

These additional passages allow excess flushing water to flow out of the reservoir.

In this context, it is further advantageous if the additional passages have smaller cross sections than the passages arranged above them.

In this way, it is ensured that the flushing water will flow through the reservoir predominantly in the plane of the above passages and therefore will not cause uncontrolled entrainment of liquid or pasty detergent whose level in the reservoir is below the level of the additional passages.

-3GB 9038 U1

Another important feature of the invention is that the filling spout of the vial is encased by a base part of the closure which is connected by a flexible hinge to a lid provided with a tab for engaging an undercut latch on the base part of the closure.

Thus, on the one hand, the lid is lost and, on the other hand, a reliable closure of the lid and thus of the vial is avoided.

Said tongue is preferably arranged at a resiliently deformable edge of the lid, so that when the lid is pressed, this deforms into an oval such that the tongue loses engagement with the undercut latch and the lid can then be opened. The opening of the lid is thus conditioned by its targeted pressing at certain points of its circumference, thus preventing the lid from opening itself or the lid from being opened by young children.

Finally, for manufacturing and construction reasons, it is further preferred that the container parts have a triangular shape with rounded corners.

Examples of technical solution

The device for dispensing a liquid or pasty detergent into a toilet bowl according to the present invention consists mainly of a reservoir 1 having a substantially triangular shape with rounded corners in the front view of FIG. At the top of the front wall 1.1. 1, a series of apertures 2 are provided which can be arranged at the same height or as shown at different heights. The dimensions and shape of these apertures 2 are not critical in themselves, but it is important that at least one of these apertures 2 allows the filling nozzle 9.1 of the vial 9 to be depicted, which will be described in more detail later in connection with Figures 5 and 6. it is preferred that at least one of the apertures 2 is circular and has a diameter corresponding to the diameter of said filling nozzle 9.1.

A hinge bracket 3 extends from the front wall 1.1 of the canister 1 upwardly by means of which the canister 1 is hinged to the edge of a toilet (not shown) and will be described in more detail below with reference to Fig. 4. This is both simple to manufacture and allows the container 1 to fit under the upper edge of the toilet bowl.

In FIG. 1, the connecting brackets 4 of the canister parts 1, which will be described in more detail with reference to FIG. 3, are further shown. In addition, FIG. 1 shows the connecting pins 5, which will also be described in detail with reference to FIG. 3.

FIG. 2 shows a rear view of the reservoir 5 of the liquid or paste detergent dispenser into the toilet bowl of FIG. The rear wall 1.2 of the reservoir 6 is visible in the upper part of which passages 6 are formed. These passages 6 preferably have the form of horizontal slots arranged, for example, with overlapping relative to one another in two rows. Below these passages 6, additional passages 6.1 are provided in the rear wall 1.2 for draining excess water from the reservoir. Here too, the connecting pins 5 can be seen.

FIG. 3 shows a view of the open reservoir 4 of the liquid or paste detergent dispenser into the toilet bowl of FIGS. 1 and 2. The front portion 7.1 and the rear portion 7.2 of the reservoir 4 with their front wall 1.1 and the rear wall 12 are visible. In addition, there are well visible connecting brackets 4, which are preferably designed as so-called film hinges, i.e. thin connecting bridges made of the material of parts 7.1, 7.2. The connecting yokes 4 are preferably produced in an injection molding operation in which both parts 7.1, 7.2 of the reservoir 5 together with all the described elements, including the suspension yoke 3, are simultaneously produced. There are also clearly visible connecting pins 5, which can be made for example such that the ends of the smaller diameter connecting pins 5 on the rear part 7.2 of the reservoir 4, with the container of FIG. It can also be seen from FIG. 3 that parts 7.1. 7.2 the reservoirs 8 can be cleaned very well and easily in such an open condition, thus removing any adhering old liquid or pasty detergent, any flush water deposits and the like.

Fig. 4 shows a side view of the closed container 4 of the liquid or paste detergent dispenser device of the toilet bowl of Figs. 1 to 3. The shape of the hinge bracket 3, which is already bent into an open hook, is ex works. for hanging on the edge of a toilet bowl (not shown). From this point of view it is also evident that if this suspension bracket extends from the front wall 1.1 of the reservoir 8, it hangs when it is hung on the edge of the toilet bowl below this edge so that it is largely concealed and minimally disturbs or obstructs mechanical cleaning toilet bowl.

FIG. 5 is a plan view of the open closure of the reservoir bottle 9 for the reservoirs of FIGS. 1 to 4. From this view, it will be seen that the base portion 8.1 of the closure that is mounted on the neck of the reservoir bottle 9 of FIG. connected to the lid 8.2 by a flexible hinge 8.3, thereby avoiding the loss of the lid 8.2. Furthermore, it can be seen that the diameter of the filling nozzle 9.1 of the reservoir vial 9 corresponds to the diameter of at least some of the openings 2 in the front wall 1.1 of the reservoir 8 in Fig. 1. Further, arcuate centering ribs 8.4, 8.5 for lid 82 are formed. a rib 8.5 remote from the flexible hinge 8.3 is provided with an undercut latch 8.6, on which, when the lid 8.2 is closed from the outside, the tongue 8.7 engages on the opposite edge of the lid 8.2. The tongue 8.7 is firmly snapped onto the undercut latch 8.1 until the lid 82 is pressed in the direction of the arrows 10. This prevents the lid 82 from being spontaneously or accidentally opened or opened by young children.

FIG. 6 shows an axial section through the closed closure of the vial 9 of FIG. 5. It can be seen how the filling nozzle 9.1 of the vial 9 is closed by the closure cap 8.2. Furthermore, there is also a snapping of the tongue 8.7 on the undercut latch 8.6 and the edges of the lid 82 against the centering ribs 8.5.

The flushing water enters the reservoir 4 through apertures 2 in the front wall 1.1 of the reservoir 4 and passes through the interior of the reservoir 4 towards the passages 6 in the rear wall 12 of the reservoir 6 which is filled with liquid or paste detergent up to the additional passages 6.1 in the rear wall 12. it is ensured that the flushing water will not entrain a larger volume of liquid or pasty detergent, but only an amount sufficient to dissolve in the flushing water during the flushing. In this way, it is ensured that, in each flushing process, substantially the same dose of liquid or paste detergent is released in the reservoir 5 until the liquid or paste detergent supply is exhausted.

Monitoring the status of the liquid or paste detergent in the reservoir 5 is facilitated by the fact that the reservoir 5 is of translucent plastic and when a liquid or paste detergent with a pronounced

The color of the liquid or pasty detergent in the reservoir 1 is then clearly visible. Due to the arrangement of the openings 2 in the front wall 1.1 of the container 1, the container 1 can be easily and cleanly replenished from the storage vial 9 without the need to remove the container 1 from the toilet bowl.
