Definitions

  • the invention relates to a valve system for the metered discharge of a flowable product from a container, in particular from a container for cosmetic or dermatological products.
  • 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

  • a special application is the use of massage heads to apply 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.
  • closures with relatively small openings and favorable geometry in combination with these substances usually ensures that the problem is 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 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.
  • BESTATIGUNGSKOPIE Systems with pumps use a standpipe to convey the substance out of the bottle.
  • the volume is equalized by air that enters the bottle through a separate channel.
  • the duct is attached so that it is only open when the pump is activated. This means that this channel is closed when the pump is at rest (usually by the pump piston itself) and that this provides further protection against contamination with foreign substances.
  • valves are usually designed in such a way that the flow of the applied substance is cut off when the corresponding application pressure is not reached, because the valve snaps back suddenly and closes the opening. This behavior ensures that the dispensing opening is only slightly contaminated and that there is therefore less suction.
  • WO 00/06460 describes a valve device for a container, which is attached in the region of the opening for the metered discharge of a medium.
  • WO 00/07899 and WO 00/07900 show valve systems which work with diaphragms.
  • WO 00/48921 shows a valve with a two-way function, in which the outlet of a liquid and the inlet of air are guaranteed by opening both ways simultaneously.
  • the object of the invention is to offer a valve system for a container, which ensures that the contents of the container are dispensed, enables back ventilation and

  • the claim 1 relates to a valve system for the metered discharge of a substance from a container, wherein a discharge opening is provided through at least one of the walls of the container for the discharge of the substance from the container and a ventilation opening through at least one of the walls of the container for back ventilation ,
  • This valve system has a first valve (outlet valve) which seals the discharge opening for the substance as long as a pressure difference between the inside and the outside of the container is less than a first predetermined limit value, and which opens the discharge opening for the substance when the pressure difference between the inside of the container and the outside of the container is greater than the first predetermined limit value, and a second valve (ventilation valve) which opens the ventilation opening for the back ventilation as long as a pressure difference between the inside of the container and the outside of the container is less than a second predetermined limit value, and which the ventilation opening for the Back ventilation seals when the pressure difference between the inside of the container and the outside of the container is greater than the second predetermined limit value.

  • the second valve consists of a flexible material and is designed in the form of a lip, which is able to close the ventilation opening. This closing can preferably take place in such a way that the lip lies over the ventilation opening and seals it in the process.
  • the variant in which the lip or parts thereof partially penetrate into the ventilation opening and thus achieve a seal is also favorable.
  • the pressure difference between the inside and outside of the container is defined as the inside pressure of the container 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 therefore 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 ventilation opening should advantageously be closed by the ventilation valve, since otherwise substance can leak through the ventilation channel when the bottle is not in use.
  • the second limit value should preferably be selected accordingly, preferably approximately to zero.
  • a negative value can also be selected for the second predetermined limit value, in particular if the container is secured against leakage in some other way, for example if it is designed as a standing container.
  • the first valve has a closure part which is essentially conical, and in particular three webs which connect the closure part to the surrounding container and which consist of a resilient material.
  • valve system according to the invention can be used very cheaply for containers in which the region of the discharge opening is designed in the form of a neck, this neck preferably having a round or oval cross section, the ventilation opening being located in a side wall of this neck and the discharge opening being preferred at the end of the neck opposite the container.
  • the second valve is designed as a cuff-shaped lip which runs around the inner wall of the neck and is capable of closing all ventilation openings for sealing.
  • “As running around the inner wall of the neck” is to be understood here in such a way that the cuff is able to completely or partially fit against the inner wall when the pressure is increased or completely or partially into it to penetrate and thus to seal the openings.

The closure part 13 is held in the raised position (see Figure 3).
  • the increase in the distance between the closure 13 and the surrounding component 16 is achieved in that the webs 15 give up the s-shape and are stretched during this process (in an alternative embodiment, for example, spiral springs can serve as webs, which are stretched during the process), or also generally an elastic or stretchable material). If the pressure inside the container is reduced again, the closure part 13 lowers due to the restoring force of the webs 15 and closes the dispensing opening 14 again, so that no residual substance can flow back into the container.
