Definitions

  • the invention relates to a valve device for arrangement in the region of an opening of a Container and for the metered discharge of a medium from the container.
  • nasal sprays that are sold in elastic bottles.
  • virus-containing nasal secretions in the bottle arrives.
  • care lotions or sunscreen or oil is also possible that other substances besides air (sand, sea water, washing substances) be sucked back into the container after the product has hit the skin was applied.
  • a special application is the use of massage heads to make a shower product apply and massage the skin.
  • massage heads to make a shower product apply and massage the skin.
  • the container contents for example, when applying mayonnaise to salads or sausage sandwiches or mustard on bratwurst.
  • the sucked back substances can often contain bacteria, viruses or fungal germs. This makes it possible that in particular Bacteria and fungal germs in the medium multiply and make it unappetizing, inedible or even toxic in extreme cases.
  • closures with small openings and favorable geometry In combination with these substances usually ensures that the problem is bearable Frame.
  • Cheap geometry means that the closure is designed that contact with the skin or other contaminated surfaces is made more difficult.
  • Airless systems have usually via a pump and a container with variable volume, for example Drag piston or inner bag (application by compressed air). These systems are also suitable for multi-chamber systems. The increased effort usually generates a lot higher cost than an elastic plastic bottle. In addition, the emptying is These systems are usually very bad.
  • valve containers for the controlled delivery of flowable or similar substances.
  • membrane valve container is the opening of the vessel by a elastic valve closed. Pressing the bottle increases the pressure in the bottle Container and the valve opens. If the pressure decreases, the valve closes again independently.
  • a re-ventilation is necessary here, even with appropriate Negative pressure in the bottle happens via this valve, taking for such a Valve construction also product residues and possibly sucked back dirt become.
  • This system ensures that the container is not used is closed and neither leaking product nor foreign substances penetrate.
  • These valves are usually designed so that the flow of the discharged substance breaks off when a corresponding application pressure is exceeded, because then the valve suddenly snaps back and closes the opening. This behavior ensures that the discharge opening is only slightly contaminated and thus the sucking back is lower.
  • WO 00/06460 describes a valve device for a container, which in the area the opening is attached to the metered discharge of a medium.
  • WO 00107899 and WO 00/07900 show valve systems which operate with diaphragms.
  • a valve with two-way function is shown in which the outlet of a Ensuring fluid and the inlet of air by simultaneously opening both ways is.
  • US 3,319,836 describes a spill-proof bottle cap in its outlet valve a return vent valve is integrated. Auslassweg and ventilation path are however not separated, so that the fluid to be dispensed partially in the re-aeration is sucked back into the container.
  • the object of the invention is to provide a valve device for a container, which ensures a release of the contents of the container, allows a return ventilation and prevents backflow of the once delivered product in the container.
  • the main claim relates to a valve device for arrangement in the area an opening of a container and the metered discharge of a medium the container, with a first valve (outlet valve), which the container opening for the medium seals, as long as a pressure difference between the container interior and the container exterior is smaller than a first predetermined limit, and which the Tank opening for the medium opens when the pressure difference between the Container interior and the Be enjoyederäffyeren greater than the first predetermined limit is, as well as with a second valve (vent valve), which the container opening for a return ventilation opens, as long as a pressure difference between the container interior and the outside of the container is less than a second predetermined limit, and which seals the container opening for re-aeration when the pressure difference between the container interior and the Be fiscaleräffyffyeren greater than the second predetermined limit, with one of the valves integrated into the other of the valves is.
  • a first valve outlet valve
  • first predetermined limit which the container opening for the medium seals, as long as a pressure difference between the container
  • the pressure difference between the container interior and the outside of the container defined as the container internal pressure minus the container external pressure in the correct mathematical, that is signed, quantities.
  • the statement in the mathematical, signed quantities also applies to the specification of the first and the second predetermined limit value.
  • the first valve is thus advantageously closed, as long as a pressure difference in the container interior, optionally in the form of a slight overpressure, relative to the container exterior is less than a first predetermined limit, and opened when the Overpressure is greater than the first predetermined limit.
  • the second is Valve at a negative pressure inside the container against the outside of the container open and closed if appropriate, if this negative pressure is not present. To achieve a negative pressure in the container interior is therefore the second predetermined limit less than zero.
  • An improvement of the inventive valve device is in the Exhaust valve to a piston valve, regardless thereof, particularly favorable but in In combination, it has been proven when it comes to the vent valve to a Poppet valve acts.
  • the first valve integrated into the second valve (vent valve).
  • the ventilation valve is advantageously a piston valve and / or the outlet valve Poppet valve.
  • FIG. 1 shows a container consisting of a container body 3, a container insert 17 with the valve device according to the invention and an essay 2, and with a container opening, wherein the container opening additionally closed by a lid 1 can be.
  • a Spring 11 in the illustrated embodiment a spiral spring, causes the piston rests on a stop 7 when exerted on the container body 3 no external pressure is, if so the pressure difference between the container interior and the container exterior is less than a first predetermined limit.
  • the lid 1 is preferably designed as a hinged lid. This is about a hinge 12 attached to an attachment 2 of the container body 3 movable.
  • the outlet channel 4 can be opened by lifting the lid 1, thereby a sealing dome 9 is made the exhaust duct 4 pulled out.
  • valves forming the valve device are permeable only one direction, only under the specified pressure conditions.
  • Figure 2 shows the discharge process by the inventive valve device when increasing the pressure in the container interior.
  • the piston 5 is moved upwards and pushes the Spring 11 together.
  • the poppet valve is closed.
  • the one represented by the strong arrow Auslassweg through the outlet opening 10 is continuous.
  • Fig. 3 the path of the incoming air in the re-aeration process is through sketched strong arrow.
  • the air passes through passages in the region of the latching parts 14 and 15, then passages in the area of the supports 13 and penetrates through the open Poppet valve 6 in the container interior a.
  • the poppet valve 6 may advantageously be designed such that it is done after Pressure equalization between the container interior and the container exterior closes again. An additional penetration of impurities is then avoided.
  • This type of closure allows an applicator to be integrated and secure exclude the substances from the application area back into the container reach.
  • the inventive valve device or one of its embodiments are constructed in such a way that that a backflow once delivered product from the applicator surface in the container is not possible. They are therefore suitable for containers for flowable Substances of all kinds, but also offer great benefits for containers, which for delivery perishable substances are provided or which high hygienic requirements have to suffice.
  • valve device is excellent for the conventional container closures and applicators suitable. These include, for example, containers for Washing and care substances (shampoo, shower gel, sunscreen, body lotion, etc.). Due to the almost excluded contamination of the contents, the proportion of strongly reducing and improving the preservative and stabilizing substances.
  • valve device results in the food sector, For example, for jam, honey, ketchup and mayonnaise, mustard, sauces and such foods.
  • valve device By integrating the return vent valve into the dispensing valve system, it is possible to in the customarily used for the production of such items injection molding to ensure high accuracy and precision. The quality of the product increases. Conveniently, the valve device may also be made in one piece This can reduce the number of production steps, the production price lowered and the accuracy of fit and functionality are improved.
  • valve can be used for ventilation instead of in the piston also in the Be integrated in the bottle body.
  • a piston valve can be used for ventilation and the outlet be designed with a poppet valve.
