Definitions
- Valve device for opening a container with back ventilation mechanism
- 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.
- 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
- Patent-he ⁇ 200-257B.doc Substances are sucked back into the container after the product has been applied to the skin.
- 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.
- 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. Most of the time, the duct is attached so that it is only open when the pump is activated. This means that this channel is closed in the idle state of the pump (mostly by the pump piston itself) and that this provides a further safeguard 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 is ensured by opening both routes simultaneously.
- the object of the invention is to provide a valve device for a container, which ensures that the contents of the container are dispensed, enables back ventilation and prevents the once dispensed product from flowing back into the container.
- the main claim 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, with a first valve (outlet valve) which seals the container opening for the medium as long as a pressure difference between the container interior and the container exterior is smaller as a first predetermined limit value, and which opens the container opening for the medium if the pressure difference between the container interior and the container exterior is greater than the first predetermined limit value, and with a second valve (ventilation valve) which opens the container opening for back ventilation, as long as a pressure difference between the interior of the container and the exterior of the container is less than a second predetermined limit value, and which seals the opening of the container for back ventilation if the pressure difference between the interior of the container and the container outer is greater than the second predetermined limit, one of the valves being integrated in the other of the valves.
- a first valve outlet valve
- first predetermined limit value which opens the container opening for the medium if the pressure difference between the container interior and the container exterior is greater
- 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.
- a negative value is essentially selected for the second predetermined limit value.
- the first valve is therefore advantageously closed as long as a pressure difference in the interior of the container, possibly in the form of a slight overpressure, is smaller than a first predetermined limit value with respect to the exterior of the container, and opened when the excess pressure is greater than the first predetermined limit value.
- the second is accordingly Valve opened when the inside of the container is opposite the outside of the container and, if possible, closed when this underpressure is not present. In order to achieve a negative pressure in the interior of the container, the second predetermined limit value is therefore less than zero.
- the second valve being integrated in the first valve (outlet valve).
- the outlet valve is a piston valve, irrespective of this, but particularly cheaply, but in combination, it has proven useful if the ventilation valve is a poppet valve.
- the first valve (outlet valve) is integrated into the second valve (ventilation valve).
- the ventilation valve is advantageously a piston valve and / or the outlet valve is a poppet valve.
- FIG. 1 container for flowable substances with a hinged lid closure with the valve device according to the invention
- FIG. 2 outlet path of the product in the container from FIG. 1
- FIG. 3 airway during the back ventilation in the container from FIG. 1
- Figure 1 shows a container consisting of a container body 3, a container insert 17 with the valve device according to the invention and an attachment 2, and with a container opening, wherein the container opening can also be closed by a lid 1.
- the valve device comprising a piston valve comprising a piston 5, which is designed to move up and down in the piston channel 51 formed by a cylinder 16, and a poppet valve 6 integrated in the piston 5.
- a spring 11 in the embodiment shown a spiral spring , causes the piston to rest on a stop 7 when no external pressure is exerted on the container body 3, that is to say when the pressure difference between the container interior and the container exterior is less than a first predetermined limit value.
- the piston valve is closed for the exit of a medium from the inside of the piston, the outlet opening 10 located in the cylinder 16 forming the wall of the piston channel 51 is closed.
- This outlet opening 10 represents part of the container opening.
- a value falls below a second predetermined limit value between the inside of the container and the outside of the container, which may be identical to the first limit value, but preferably smaller, in particular negative, the poppet valve 6 is opened. In particular, this is the case when the pressure inside the container is lower than the pressure on the outside of the container.
- the piston 5 in the cylinder 16 is moved against the spring 11 until the outlet opening 10 is cleared laterally in the wall of the cylinder 16 (see also FIG. 1a) ).
- the product can then enter the outlet channel 4 through this outlet opening 10.
- a plurality of outlet openings can also be provided in the wall of the cylinder 16 in order to increase the discharge quantity.
- the lid 1 is preferably designed as a hinged lid. This is movably attached to an attachment 2 of the container body 3 via a hinge 12.
- the outlet duct 4 can be opened by lifting the cover 1, thereby pulling a sealing mandrel 9 out of the outlet duct 4.
- the ventilation path is optimized with regard to contamination through a constructive design, contamination is very difficult.
- the path of the incoming air during the rear ventilation runs under the supports 13 and through the latching parts 14 and 15 for the attachment 2, which are permeable to air due to small interruptions not shown.
- the attachment 2 is fastened on the container body 3 by a system of locking parts (locking hooks 14 and snap hooks 15).
- locking hooks 14 and snap hooks 15 the state of the art offers further advantageous possibilities (threads, snap-in tapes, crimping, etc.).
- the container insert 17 containing the outlet channel 4 is held by the container body 3 via supports 13 and sealed off by a sealing lip 8.
- a sealing lip 8 Various designs are possible for the design of this seal (barrel, cone, lamellae, cylinder). Inserting a sealing ring or a washer is advantageous.
- Figure 1a shows the discharge process by the inventive valve device when the pressure inside the container increases.
- the piston 5 is displaced upwards and compresses the spring 11.
- the poppet valve is closed.
- the outlet path through the outlet opening 10 represented by the strong arrow is continuous.
- the path of the inflowing air in the back-ventilation process is outlined by a strong arrow in FIG. 1b.
- the air passes through passages in the area of the latching parts 14 and 15, then passages in the area of the supports 13 and penetrates through the opened poppet valve 6 into the interior of the container.
- the poppet valve 6 can advantageously be designed such that it closes again after pressure equalization between the interior of the container and the exterior of the container. An additional penetration of contaminants is then avoided.
- This type of closure allows, for example, an applicator to be integrated and safely excluded that substances can get back into the container from the application surface.
- a reversed piston valve (the opening 10 now serves as a ventilation opening) can be used as a ventilation valve, which has a poppet valve (passage can be switched from the inside to the outside).
- the inventive valve device or one of its embodiments is constructed in such a way that a product once it has been dispensed cannot flow back from the applicator surface into the container. They are therefore suitable for containers for flowable substances of all kinds, but also offer great advantages for containers which are intended to dispose of perishable substances or which have to meet high hygienic requirements.
- valve device is outstandingly suitable for the conventional container closures and applicators.
- containers for washing and care substances shampoo, shower gel, sun milk, care lotion, etc. Due to the almost excluded contamination of the contents, the proportion of preserving and stabilizing substances can be greatly reduced.
- valve device is in the food sector, for example for jam, honey, ketchup and mayonnaise, mustard, sauces and such foods.
- valve device By integrating the back-venting valve into the dispensing valve system, it is possible to ensure high accuracy and precision in the injection molding process usually used for the production of such objects.
- the quality of the product increases.
- the valve device can advantageously also be produced in one piece, as a result of which the number of production steps can be reduced, the production price can be reduced and the accuracy of fit and the functionality can be improved.
- valve for ventilation can also be integrated into the bottle body instead of in the piston.
- a piston valve can also be used for ventilation and the outlet can be designed with a poppet valve.
