Definitions

• the invention relates to a dosing container for receiving and dispensing, in particular, powder detergent or the like, consisting of a textile sack with a mouthpiece ring part arranged at the edge of the sack opening.
• Such metering systems which are generally used for powdery detergents, have the advantage over can-like compact containers of the smaller space requirement for storage, etc. and, above all, that of the less noisy movement during use.
• disadvantages are - based on the textile sack - wear-related short life and, above all, the problem of the correspondingly frequently occurring, in itself unnecessary disposal of the hard part, i. H. of the mouthpiece ring part.
• the object of the invention is to design a generic metering container with a structurally simple design in a more environmentally friendly and easy to handle manner, but without having to forego the indicated advantages.
• this object is achieved according to the invention in that the sack has an overhanging rim ring part which is firm in comparison with the sack material and which is detachably clamped in the ring ring part.
• a generic metering container of increased utility value is achieved, which is primarily due to the constant reusability of the hard part requiring more disposal, namely the mouthpiece ring part.
• the more economical, but more wear-prone part made of textile material, ie the sack, can now be replaced by the consumer, for example after the original equipment has been factory-fitted, in the course of subsequent deliveries, since the sack with its overhanging mouth ring part can be releasably clamped in the mouthpiece ring part is held.
• the dosing container consists of a soft, wear-prone sack and a mouthpiece ring part which is hard but resistant to the sack, the mouthpiece ring part and the textile sack being easily assembled into the dosing container, but also just as easy to separate from one another .
• the dosing container can be supplied ready-made or can also be delivered separately according to the ring ring part and the sack, in which case the user assembles these parts into the dosing container. The consumer can then decide when the sack should be replaced. It is then only necessary to procure and replace the inexpensive sack. The more expensive hard plastic part can be reused. Compared to known dosing containers for detergents, this means cost savings for both the consumer and the manufacturer due to the lower material consumption. In particular, the fact that it is no longer necessary to replace the entire metering container significantly reduces the environmental impact due to plastic waste.
• the simple and convenient interchangeability of the sack is achieved in that the sack is only releasably clamped in the mouthpiece ring part with its projecting rim ring part. This clamp connection is easy to loosen. Elaborate fastening devices and mechanisms are not necessary.
• the metering container enables the detergent to be filled by the consumer to be continuously dispensed to the wash liquor in the drum of a washing machine, which in conventional washing machines begins with the first rotations of the drum.
• the dosing container is therefore filled with detergent and placed in the drum of washing machines.
• the dosing container since the dosing container mostly comes into contact with the laundry to be washed with its textile material, it can also be used to achieve a particularly gentle treatment of the laundry. Finally, when used in the washing machine, the dosing container is also accompanied by a low level of noise compared to conventional dosing containers.
• the invention provides that the mouth edge ring part consists of a flexible ring, which is more rigid than the bag material and has a bag opening edge attached to it consists.
• a ring part can be adapted, in particular from plastic, to the mouthpiece ring part without great effort. This also makes many possible variations for the design of the rigidity of the ring part.
• the sack is just as easy to attach to it.
• the edge of the bag opening is advantageously fastened to the ring by means of gluing or welding.
• the invention provides that the edge of the sack opening is formed from the sack wall to the mouth wall ring part and is solidified by means of thermal treatment. In this way it is possible to form the mouth rim part directly from the sack wall and to fix it in the mouthpiece ring part for attachment.
• the mouth rim part then consists only of the sack material and has no plastic components.
• the invention further provides in an expedient embodiment that the mouthpiece ring part has a contact surface for the mouth rim part.
• the invention provides that a cover element is assigned to the mouthpiece ring part, which consists of a cover ring part with a cup-shaped curvature of the same material, which in the closed position rests non-positively on the mouth rim part.
• the sack is securely clamped in the mouthpiece ring part while at the same time ensuring releasability.
• a particularly secure and slip-proof fixing of the sack in the mouthpiece ring part is achieved according to another invention in that the bottom outer edge of the arch in the closed position is non-positively against the inner edge of the mouth edge ring part.
• a device which is particularly suitable for fixing the sack and, in particular, can be produced as an injection molded part with little effort, is characterized in accordance with the invention in that a hinged cover element with at least one through-opening can be snapped onto the mouthpiece ring part and locked with the mouthpiece ring part is articulated.
• the cup-like arching In order to ensure an opening sufficient for the continuous dispensing of the washing powder from the sack, even with the cover element quasi closing the sack opening, provision is made according to a further invention for the cup-like arching to have several slot-shaped through openings in its base.
• connection of the cover element and the mouthpiece-ring part in particular the one-piece production of which is easy to implement, can be achieved in a simple manner, in particular in the case of injection molding of these parts, in that the mouthpiece-ring part and the cover element are connected to one another by means of a film hinge.
• the invention provides in a further development that the cover element has a latching tongue or catch which engages in an opening of the mouthpiece ring part.
• the latching tongue and the opening are expediently arranged opposite the film hinge.
• the invention provides that the mouthpiece ring part and the cover element consist of plastic.
• FIG. 3 is a side view of the sack of FIG. 2,
• FIG. 5 is a plan view of the mouthpiece ring part and the cover element according to FIG. 4 from the inside and in
• FIG. 6 shows a section along the line V-V in FIG. 4.
• Fig. 1 shows the total designated 1 dosing container.
• This consists of a textile sack 2 and a mouthpiece ring part 3 arranged at the edge thereof.
• the sack has a protruding rim part 4 of the mouth rim which is firm compared to the sack material.
• the mouth rim part 4 consists of a flat ring 5 made of a flexible material which is more rigid than the sack material.
• the ring 5 is made of plastic.
• the edge of the bag opening 6 formed from the bag wall is fastened to the ring 5 by gluing or welding.
• the mouth edge ring part 4 thus consists of the ring element 5 and the sack opening edge 6 attached to it.
• the mouth edge ring part 4 consists only of the bag opening edge 6.
• the edge of the bag opening 6 is formed from the wall of the bag into the ring rim part 4 and solidified and stiffened by thermal treatment.
