Definitions

  • the invention relates to a container with at least two product chambers, in which the product chambers are connected in such a way that they form a common multi-chamber container system, and each of the product chambers has an opening for dispensing the product.
  • this product residue is usually contaminated with splash water, since it is used at the sink or in the shower.
  • the shampoo residues around the pouring opening have been stripped off by hand and then sweat, skin residues or other substances are also sucked into the skin.
  • nasal sprays that are sold in elastic bottles. With this application it is possible that viral nasal secretions can get into the bottle.
  • care lotions or sun milk or oil it is also possible that other substances besides air (sand, sea water, washing Substances) are sucked back into the container after the product has been removed.
  • a special application is that with the simultaneous use of massage heads to dispense a shower product and massage the skin.
  • substances are detached from the skin during massaging and sucked into the opening of the massage head.
  • the problem of contamination of the container contents arises, for example, when applying mayonnaise to salads or sausage bread or mustard to sausage.
  • the substances sucked back can often contain bacteria, viruses or fungal germs. This makes it possible for bacteria and fungal germs in particular to multiply in the contents and thereby make them unsavory, inedible or, in extreme cases, even toxic.
  • the substances to be dispensed from different product chambers are mixed during the application.
  • Such packaging can be used, for example, for two-component adhesives, combinations of washing and care substances or the like.
  • the aim of this packaging is to keep the two or more components separate during storage, but to apply them together during use.
  • the mixture of the two or more components can be partially returned to the individual chambers of the multi-chamber container in the systems on the market. This can lead to clouding, contamination or contamination or, as in the case of the two-component adhesive, for example, to undesired reactions in one or more of the chambers.
  • the product can become unusable.
  • the shelf life of individual components can be impaired, for example that of the care substance by the introduction of surfactants from the washing substance.
  • closures with relatively small openings and favorable geometry in combination with these substances usually ensures that the effects of the problem described above are kept within reasonable limits.
  • Favorable geometry means that the closure is designed so that contact with the skin or other contaminated surfaces is made more difficult.
  • Airless systems usually have a pump and / or a container with a variable volume, for example a drag piston or inner bag (delivery by compressed air). These systems are also suitable for multi-chamber systems. The increased effort usually creates much higher costs than an elastic plastic bottle. In addition, the residual emptying of these systems is usually very bad.
  • EP 875 460 B1 presents a multi-chamber container, the closure of which provides two separate dispensing openings. This largely avoids sucking back the mixed substances. However, it is also disadvantageous in this system that dirty water is withdrawn or that the contents can be contaminated.
  • the object of the invention is to provide a multi-chamber container which is suitable for sensitive substances and prevents contamination of the substances in the chambers by the content of the other chambers.
  • Claim 1 therefore relates to a container with at least two product chambers, the product chambers being connected in such a way that they form a common multi-chamber container system, and each of the product chambers having at least one product discharge opening.
  • at least one valve device is provided in the area of the product discharge opening, which allows the discharge of a substance located in the product chamber (valve device for the product discharge), but prevents the discharged substance or parts thereof from flowing back into the product chamber, and also back ventilation into the product chamber is made possible and the product discharge openings of the individual product chambers open into a common outlet channel.
  • the container according to the invention if at least one rear ventilation opening is provided for the rear ventilation, which opening can be opened and closed by a rear ventilation valve device.
  • At least one of the valve devices has a first valve which seals the product discharge opening for the substance as long as a pressure difference between the interior of the chamber and the exterior of the container is less than a first predetermined limit value, and which the product discharge opening for the substance opens if the pressure difference between the interior of the chamber and the exterior of the container is greater than the first predetermined limit value, and a second valve which opens a second opening (ventilation opening) for back-ventilation as long as there is a pressure difference between the interior of the chamber and the exterior of the container is less than a second predetermined limit value, and which seals the second opening for a back ventilation if the pressure difference between the interior of the chamber and the exterior of the container is greater than the second predetermined limit value.
  • the pressure difference between the inside and outside of the container is defined as the inside pressure minus the outside pressure of the container in the correct mathematical, ie signed values.
  • the specification in the mathematical, signed values also applies to the specification of the first and the second specified limit value.
  • the first valve is thus advantageously closed as long as an overpressure in the interior of the container relative to the exterior of the container is less than a first predetermined limit value, and opened when the overpressure is greater than the first predetermined limit value.
  • the second valve is open in the case of a negative pressure in the interior of the container relative to the outer side of the container and, if appropriate, is closed when this negative pressure is not present.
  • the second specified limit value is therefore less than zero in order to achieve a vacuum inside the container.
  • the back ventilation opening is in the first valve and / or the second valve is integrated in the first valve.
  • the container in such a way that a piston valve is used as the first valve. It is also advantageous if the second valve is a poppet valve.

  • the first valve (dispensing valve) is in the form of a sealing washer made of a flexible material.
  • the second valve (back ventilation valve) is designed as a circumferential cuff-shaped lip on the inner wall of the area of the chamber which has the second openings and is able to seal over all the second ones Openings.
  • Such multi-chamber containers are excellently suitable for flowable substances of all kinds, in particular for perishable substances or for those which have to meet high hygienic requirements.
  • shoe polish or other cleaning and care / preserving substances in particular those with a brush or a sponge on the container for cleaning clothes
  • the container particularly suitable for use with mutually incompatible substances, for which the addition of stabilizing components (emulsifiers, antioxidants and the like) would otherwise be necessary. Furthermore, it is possible to provide two substances at the same time with one container, which react with one another in a desired reaction, for example both components of a two-component adhesive.
  • stabilizing components emulsifiers, antioxidants and the like
  • the container according to the invention relate to the storage of substances which generate heat or cold when mixed (for example for the therapeutic field), furthermore those which foam or release substances which are readily volatile and / or oxygen or are moisture resistant.
