Definitions
- the present invention relates to a dosing device for liquid and free-flowing products, a container with an integrated dosing device, and a product dispenser that can be equipped with a container of the aforementioned type.
- the present invention further relates to a system comprising a product dispenser and at least one corresponding container.
- Liquid and free-flowing products or substances and substance mixtures include, in particular, low to high-viscosity liquids or liquid mixtures and viscoelastic materials.
- emulsions and suspensions or dispersions should also be mentioned in particular.
- the products mentioned can be, for example, liquids, gels, creams, ointments or lotions for body care and/or cleaning, pharmaceuticals, technical liquids, oils and fats or the like.
- bottles, cans, tubes, canisters, containers and composite cartons, etc. are only mentioned here as examples.
- the aforementioned containers can often be provided with a screw-on pump lid with a lifting pump, a pipette or another dosing device.
- bottles with dosing devices often consist of a large number of components which have to be assembled at great expense and because of the different materials used (for example components made of different plastics together with components made of metal, such as springs etc.) are difficult and in particular not completely recyclable.
- Foil bags are considered one of the most cost-effective and environmentally friendly packaging for liquid and flowable products today. Foil bags are basically for many Known for years, but were rather unpopular because of their poor handling and high sensitivity to mechanical damage.
- foil bags for example as stand-up bags, spout bags, flat bags and gusseted bags, are experiencing a certain popularity again.
- foil bags in particular of foil bags with a tear-off edge
- a disadvantage of foil bags is the lack of resealability.
- the contents of the opened foil bag are also exposed to an increased risk of e.g. hygienically unsafe contamination and microbial infestation as well as faster oxidation.
- Foil bags with a welded-in, resealable spout, also known as a spout at least partially alleviate the problem described.
- One of the problems to be solved by the invention is therefore to provide a dosing device for liquid and free-flowing products that is improved in particular in the points mentioned, which is low in complexity, simple and efficient to manufacture with little use of materials, and good recyclability.
- the invention is also based on the object of offering a container, an associated product dispenser and a system made up of container and product dispenser.
- a dosing pump with the features of patent claim 1, a container with the features of patent claim 13, a product dispenser with the features of claim 14 and a system with the features of claim 15 are proposed to solve the above-mentioned tasks.
- the present disclosure relates to a dosing device, henceforth also referred to as a dosing pump, for integration into a container.
- the metering pump includes a pump housing with a pumping chamber.
- the pump housing also has a pump inlet and a pump outlet.
- the pump chamber is delimited by a pump chamber floor and an elastically deformable pump dome.
- the elastically deformable pump dome is pressed in when the metering pump is actuated while the fluid connection from the pump inlet to the pump chamber is closed, then fluid is pumped from the pump chamber to the pump outlet or out of the pump outlet due to the volume reduction in the pump chamber.
- the fluid connection can be closed, for example, by the pump inlet being covered by a container wall (or film) lying against the dosing pump when the pump dome is pressed in.
- a non-return valve often also referred to as a non-return valve, can be provided in the fluid connection between the pump inlet and the pump chamber.
- the pump chamber fills up again with fluid that continues to flow from the direction of the pump inlet or is sucked in there.
- the pump chamber base can be rigid, ie inflexible, or flexible in some embodiments.
- the pump housing is advantageously designed with thin walls.
- a pump housing is considered “thin-walled” if the majority (>50%) of the surface, especially in areas with a homogeneous wall thickness, has a material thickness of less than 3 mm, in particular less than 1.5 mm, preferably less than 0.8 mm having.
- the pump housing can be assembled from a first pump housing section and a second pump housing section.
- the pump dome is then part of the first Pump housing section and the pump chamber floor is part of the second pump housing section.
- a metering pump as described above can be manufactured particularly easily and efficiently in a few steps.
- the material requirement is very low. In addition to the price, this also reduces energy consumption, C02 emissions and plastic waste compared to other packaging solutions with more complex dosing devices.
- the dosing pump according to the invention enables economical packaging of fluid mass products and thus expands the possible uses of thin-walled containers, in particular foil bags.
- the film bag with the integrated dosing pump according to the invention can replace the commercially available bottles with dosing devices in various branches of fluid-like products as a cheaper and more ecological alternative.
- a dosing pump integrated into the container is also particularly advantageous from a hygienic point of view.
- the first pump housing section and the second pump housing section are preferably designed together as an integral component and connected by means of a film hinge.
- the integral component does not have any undercuts in a defined demolding direction, starting from the parting plane of the injection molds.
- this aspect simplifies the manufacturing process and the necessary tools considerably.
- the handling of the semi-finished products is also simplified, since the integral component only has to be folded over on the film hinge. The relative positioning of the first pump housing section and the second pump housing section is also facilitated in this way. At the same time, the number of parts to be handled is reduced.
- the first pump housing section and the second pump housing section can have or consist of a thermoplastic material and be welded in a joint area.
- Laser transmission welding or ultrasonic welding, for example, is particularly suitable for this purpose.
- Thermoplastics are readily and cheaply available, can be recycled very easily and have material properties that are very suitable for the application.
- the dosing pump can thus be produced entirely from a flexible plastic material using the plastic injection molding process, vacuum pressing process, thermoforming process or other suitable process.
- the first pump housing section and the second pump housing section have alignment geometries that are congruent to one another.
- they can include centering pins or cones and corresponding holes or a circumferential groove and a corresponding tongue. This simplifies precise alignment of the pump housing sections.
- the metering pump has an outlet valve.
- the outlet valve is arranged in a fluid connection from the pump chamber to the pump outlet and is designed as a backflow preventer.
- a non-return valve between the pump chamber and the pump outlet supports the efficiency of the pump.
- the suction of ambient air into the fluid connection or the pump chamber is also avoided. This is advantageous from a hygienic point of view and can extend the shelf life of a product to be conveyed with the dosing pump.
- the outlet valve can have a closure part with a convex sealing surface and a sealing seat corresponding to the closure part.
- the closure part can preferably be an integral part of the first or the second pump housing section and the sealing seat accordingly an integral part of the other pump housing section, ie the second or the first pump housing section.
- the closure part of the outlet valve can preferably comprise a sealing bead running around the convex sealing surface.
- the sealing seat of the outlet valve can also have an annular web that corresponds to the sealing bead. When the outlet valve is closed, the web in the sealing bead rests on the closure part at least on one side and preferably on both sides.
- the outlet valve can have a bead running around the outlet valve opening on the outside and an outlet ring channel arranged outside of the bead.
- the dosing pump can have a further backflow preventer in the fluid connection from the pump chamber to the pump outlet.
- the further backflow preventer can in particular be an additional check valve connected in series with the outlet valve in fluidic communication.
- the reliability of the seal is increased by several sealing levels one behind the other. This reduces the risk of fluid escaping from the dosing pump or container or air entering the container.
- the additional non-return valve can be a second outlet valve.
- the second outlet valve can then have a structure comparable to that of the first outlet valve.
- the pump dome can have a so-called decompression crown.
- the decompression crown comprises a plurality of decompression teeth, which are designed in such a way and are arranged at a distance from one another in a ring around the pump inlet such that two decompression teeth lying next to one another each form a decompression channel between them.
- Decompression teeth are elevations/protuberances on the outer surface of the pump dome, which have such a height and such small radii that gaps are formed between the pump dome and the container wall/foil surrounding the metering pump.
- a pressure equalization can take place at any time via the decompression channels, even when the foil/wall of the surrounding container/foil bag nestles directly against the pump dome.
- the pump dome can have at least one peripheral and preferably a plurality of concentrically arranged spring beads.
- the spring beads can have a lower material thickness than the rest of the pump dome. The spring beads improve the tactile/haptic sinking behavior of the pump dome.
- the pump dome may have a plurality of decompression teeth.
- the decompression teeth can be arranged regularly spaced from each other on the pump dome.
- the surface of the pump dome can be designed with nubs, for example.
- the pump inlet can be arranged centrally in the pump dome.
- the pump inlet is covered by the container wall/foil that is pressed on when the pump dome is pressed in.
- a separate inlet valve as a non-return valve can then be omitted.
- the pump inlet can be located outside of the pumping chamber.
- the metering pump then includes an inlet valve which is arranged in a fluid connection from the pump inlet to the pump chamber and is designed as a backflow preventer.
- the non-return valve in the fluid connection between the pump inlet and the pump chamber ensures that the liquid or free-flowing product is conveyed in the right direction.
- the pump chamber floor can have one or more reinforcement beads in order to increase the rigidity.
- the pump housing can have one or more grooves which are set up and arranged to form a fluid connection between the pump inlet and the pump chamber and/or between the pump chamber and the pump outlet at least in sections.
- the container wall/foil can be attached to the pump housing, in particular welded. The container wall/foil then forms the missing wall of the fluid channel.
- the pump housing can have at least one fastening area for entering into a snap connection.
- the fastening area can have a latching tab, a latching lug and/or an edge for gripping behind and preferably another edge for positioning.
- the pump housing can have at least one bacteriostatic, bactericidal or fungicidal element, which is preferably arranged in a fluid connection from the pump chamber to the pump outlet.
- the dosing pump can have a leak-proof device.
- the leakage protection is then set up to seal a fluid connection between the pump chamber and the pump outlet.
- the leak guard is designed to be removed, loosened, or mechanically destroyed by a user to release fluid communication.
- the metering pump described above is intended to be placed in a thin-walled container and welded to the container.
- the present disclosure also relates to such a container with an integrated dosing pump.
- the container and the dosing pump are preferably made of the same or at least a thermoplastic material of the same type.
- the containers can be foil bags.
- the container can also be a thin-walled plastic container in which the wall has a material thickness that is so stiff that it is no longer commonly understood as a film (for example from a wall thickness of approx. 0.3 mm), but at least includes locally limited flexible areas.
- the flexible areas can be provided, for example, by means of joint beads with a reduced wall thickness.
- the container is suitable for dosing fluid products from areas such as perfumery, cosmetics, pharmacy, hygiene, personal care, home care, food (in particular beverages and dairy products), dietary supplements, technology and other areas.
- the containers can, provided they are film bags, side-sealed bags, doypacks, flowpacks, flat bags, tubular bags with a Euro hole, chain bags, contour bags, gusseted bags, bag-in-box bags, easy packs, block-bottom bags and other types of film bags.
- the containers can also be made of thin-walled plastic, which, however, is too stable to qualify as foil. Containers of this type then have elastic areas, for example due to articulated beads.
- a product dispenser for accommodating a container with a dosing pump as described above, the product dispenser having holding means for fastening the container and a flexibly mounted pressure bolt for manual actuation of the dosing pump and/or an actuator seat for accommodating a motor-operated actuator for automatic actuation of the Has dosing pump.
- a corresponding system comprises a product dispenser and a container with a dosing pump, as previously described.
- the system can also have a motor-driven actuator for automatically actuating the dosing pump in the container.
- the actuator can easily be integrated into the product dispenser.

- FIG. 17A, 17B, 17C show a thin-walled container with a further dosing pump 1. Because of the greater material thickness of the container 100 shown and the resulting rigidity of the material, one should no longer speak of a film bag in this variant.
- the pump chamber base 5 can optionally have one or more reinforcement beads.
