Definitions

  • the invention relates to a valve system for the metered discharge of a free-flowing product from a container, in particular from a container for cosmetic or dermatological products.
  • nose sprays which are sold in flexible bottles. Such bottles are typically configured so that it is possible for virus-containing nose secretions to make their way into the bottle.
  • body-care lotions or a suntan milk or oil it is likewise possible, in addition to air, for other substances (sand, sea water, washing substances) to be sucked back into the container once the product has been applied to the skin.
  • One particular application is the use of massage heads in order to apply a shower product and to massage the skin.
  • substances which are sucked back may often contain bacteria, viruses or fungi. It is thus possible, in particular, for bacteria and fungi to multiply in the contents and thus render the latter unappetizing, 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.
  • a favorable geometry means that the closure is configured such that contact with the skin or other contaminated surfaces is made difficult.
  • Airless systems usually have a pump and a container with variable volume, for example a drawing plunger or inner bag (discharged by way of compressed air). These systems are also suitable for multi-chamber systems.
  • the increased outlay usually gives rise to very much higher costs than a flexible plastic bottle. Moreover, residue removal from these systems is usually very poor.
  • a further development for dispensing systems for containers relates to the installation of valve systems for dispensing free-flowing or similar substances in a controlled manner.
  • the opening of the vessel is closed by an elastic valve. Applying pressure to the bottle increases the pressure in the container and the valve opens. If the pressure decreases, the valve closes again of its own accord.
  • readmission of air is necessary here too, this also taking place via said valve in the case of a corresponding negative pressure in the bottle, product residues and any contamination also being sucked back with such a valve structure.
  • This system ensures that, when not in use, the container is closed and product does not pass out, nor do foreign substances pass in.
  • valves are usually configured such that the stream of substance discharged ceases when the discharge pressure drops below a corresponding value, because the valve then abruptly snaps back and closes the opening. This ensures that the dispensing opening is only contaminated to a small extent, and the sucking-back action thus also takes place to a lesser extent.
  • WO 00/06460 describes a valve device which is intended for a container and is fitted in the region of the opening for the metered discharge of a medium.
  • WO 00/07899 and WO 00/07900 disclose valve systems which operate with diaphragms.
  • WO 00/48921 discloses a valve with a two-way function in the case of which the discharge of a liquid and the ingress of air are ensured by both routes being opened at the same time.
  • One embodiment of the invention provides a valve system for a container that: (1) ensures that the container contents are dispensed; (2) allows readmission of air; and (3) prevents the product, once dispensed, from flowing back into the container.
  • a valve system is configured for the metered discharge of a substance from a container.
  • a dispensing opening is provided through at least one of the walls of the container for discharging the substance from the container.
  • an air-admission opening is provided through at least one of the walls of the container for the readmission of air.
  • This valve system has a first valve (discharge valve), which seals the dispensing opening for the substance as long as a pressure difference between the interior of the container and the exterior of the container is smaller than a first predetermined limit value and which opens the dispensing opening for the substance if the pressure difference between the interior of the container and the exterior of the container as larger than the first predetermined limit value, and also has a second valve (air-admission valve), which opens the air-admission opening for the readmission of air as long as the pressure difference between the interior of the container and the exterior of the container is smaller than a second predetermined limit value and which seals the air-admission opening for the readmission of air if the pressure difference between the interior of the container and the exterior of the container is larger than the second predetermined limit value.
  • discharge valve discharge valve
  • air-admission valve which opens the air-admission opening for the readmission of air as long as the pressure difference between the interior of the container and the exterior of the container is smaller than a second predetermined limit value and which seal
  • the second valve here comprises of a flexible material and is designed in the form of a lip which is capable of closing the air-admission opening. This closure may preferably take place such that the lip positions itself over the air-admission opening and seals the latter.
  • the variants in which the lip or parts thereof penetrates/penetrate, in part, into the air-admission opening, and thus achieves/achieve sealing, is also advantageous.
  • the pressure difference between the interior of the container and the exterior of the container is defined as the internal pressure of the container minus the external pressure of the container in the correct mathematical values, that is to say ones provided with an algebraic sign. Giving the mathematical values provided with an algebraic sign likewise applies to the way in which the first and the second predetermined limit values are given.
  • the first valve is thus advantageously closed as long as a positive pressure in the interior of the container in relation to the exterior of the container is smaller than a first predetermined limit value, and is open if the positive pressure is larger than the first determined limit value.
  • the second valve is open in the case of a negative pressure in the interior of the container in relation to the exterior of the container, and is advantageously closed when this negative pressure is not present.
  • the air-admission opening should advantageously be closed by the air-admission valve in the state in which the internal pressure of the container corresponds approximately to the external pressure, since otherwise, if the bottle is not being used, substance can run out through the air-admission channel.
  • the second limit value may preferably be selected correspondingly, preferably approximately zero. It is also possible to select a negative value for the second predetermined limit value, in particular if the container is secured against leakage in some other way, for example if it is configured as a stand-up container.
  • the first valve has a closure part, which is of essentially conical configuration, and in particular three crosspieces, which connect the closure part to the surrounding container and which are made of a resilient material.
  • the inventive valve system can be used very advantageously for containers in which the region of the dispensing opening is designed in the form of a neck, this neck preferably having a round or oval cross section, the air-admission opening being located in a side wall of this neck, and the dispensing opening preferably being located at that end of the neck which is located opposite the container.
  • the second valve is designed as a sleeve-like lip which runs around the inner wall and is capable of closing all the air-admission openings for sealing purposes.
  • “Runs around the inner wall of the neck” is to be understood here as meaning that the sleeve is capable, in the case of an increase in pressure, of positioning itself wholly or partially against the inner wall, or of penetrating wholly or partially into the same, and thus of sealing the openings.
  • this sleeve should butt against the wall.
  • valve is thus sealed when the container is not in use (“rest state”); even in the case of a small negative pressure in the container, pressure equalization takes place by virtue of air flowing in.
  • FIG. 1 shows the region of the discharge opening in a container having a valve system according to one embodiment of the invention.
  • FIG. 2 shows the valve element of a valve system according to a particular embodiment of the invention.
  • FIG. 3 shows the region of the discharge opening in a container having a valve system according to one embodiment of the invention.
  • the discharge valve is in an open position.
  • FIG. 4 shows the region of the discharge opening in a container having a valve system according to an embodiment of the invention. This figure shows the route taken by air as the air enters through the open lip valve during the readmission of air.
  • FIG. 5 shows the region of the discharge opening in a second embodiment of a container having a valve system according to an embodiment of the invention.
  • FIG. 1 shows a container, in this case in particular for cosmetic preparations, in the region of the discharge opening.
  • the container is designed in the form of a neck 1 .
  • An attachment part 3 which has an internal thread, and contains the inventive valve system, can be screwed onto said neck 1 , which is provided with a corresponding screw thread 2 on its outside.
  • the attachment part 3 is provided with a component 16 , which can be plugged, clipped, welded or similarly fitted into the attachment part 3 , a reversible fastening also being possible.
  • This component 16 is fastened in a sealing manner all the way round in relation to the attachment part 3 .
  • the attachment comprising the parts 3 and 16 , to be configured in one piece.
  • the container can be closed by a hinged lid 9 , which is connected to the container by the hinge 8 .
  • the attachment part 3 has an antechamber 4 that is configured such that, with the attachment part 3 screwed on, the container is sealed in the region of the designations 5 , with the result that a substance located in the container cannot escape here at any time.
  • the wall of the antechamber 4 contains a discharge channel 6 , at the top end of which the discharge valve 7 is located.
  • the antechamber 4 is sealed all the way round in relation to the component 16 .
  • the discharge valve 7 is designed in the form of a preferably conically tapering closure part 13 for the dispensing opening 14 ; the dispensing opening 14 is preferably also conical.
  • a plan view of the valve element 7 (discharge valve) is shown in FIG. 2.
  • the closure part 13 is connected to the container, in this case to the component 16 , by a plurality of flexible or resilient crosspieces 15 . In the embodiment illustrated here, the connection is realized by three s-shaped crosspieces 15 made of a flexible material. If a pressure is then exerted from the interior of the container, the closure part 13 is raised and releases from the dispensing opening 14 . This allows the substance to pass out of the container. The closure part 13 is retained in the raised position (see FIG. 3).
  • the increase in the distance between the closure 13 and the surrounding component 16 is achieved in that, during this operation, the crosspieces 15 lose the s-shape and are straightened out (in an alternative embodiment it is possible to use, as crosspieces, for example helical springs, which are expanded during the operation, or else, generally an elastic or expansible material). If the pressure in the interior of the container is reduced again, then the closure part 13 is lowered on account of the restoring force of the crosspieces 15 and closes the dispensing opening 14 again, with the result that no residual substance can flow back into the container.
  • the hinged lid 9 may advantageously be configured such that, in the closed state, it presses the closure part 13 into the dispensing opening 14 and thus improves the sealing.
  • the closure part 16 may also have a geometry which is other than conical (sphere, ellipsoid, cylinder, etc.).
  • air-admission openings 10 which are located in the wall between the antechamber 4 and the exterior of the container. In the figure illustrated here, these air-admission openings 10 are located in the attachment part 3 . This ensures the passage of air (see the dashed-line arrow in FIG. 4) through the screw thread 2 .
  • the air-admission openings 10 may be closed by an air-admission valve 11 .
  • This air-admission valve 11 is in the form of a lip, in this case in particular of a sleeve of lip-like cross section running around the antechamber 4 , and is made of a flexible material.
  • this sleeve (air-admission valve 11 ) is fitted in the component 16 ; the bottom part projects into the antechamber 4 and is preferably formed such that it is inclined in front of the air-admission openings 10 . If the pressure in the container is increased, this gives rise to the conditions shown in FIG.
  • the substance located in the container passes in through inlet openings 12 in the base of the antechamber 4 .
  • the pressure air pressure or pressure from the substance which has passed in
  • the air-admission valve 11 is pressed onto the air-admission openings 10 .
  • the air-admission valve 11 is preferably of thin-walled configuration in the bottom region, with the result that the pressing action is greatest here.
  • the valve for the substance located in the container closes off in a sealed manner in the region of designations 17 ; the air-admission openings 10 in this case are closed. It is not possible for substance to pass out here.
  • the air-admission valve 11 opens and allows air to pass in through the air-admission openings 10 and in the downward direction, out of the air-admission valve 11 , into the antechamber 4 until the negative pressure in the container is more or less equalized.
  • a dashed-line arrow is used to illustrate the route taken by the air as it passes in at the open air-admission valve 11 for that embodiment of the invention which is illustrated here (in the region of the screw thread 2 , the air can pass in along this screw thread 2 ).
  • the encircling, sleeve-like configuration of the air-admission valve 11 ensures that, when the internal pressure of the container is increased, this air-admission valve 11 is subjected uniformly to the pressure and the air-admission openings 10 are thus closed uniformly. The best possible sealing can be achieved as a result.
  • FIG. 5 shows, by way of example, a container with an inventive valve system in which, with an otherwise similar construction of the container, the discharge valve 7 is configured in an alternative manner.
  • the fixable component 16 here contains one or more dispensing openings 20 , which can be closed and opened by the discharge valve 7 .
  • This valve comprises a valve plate 18 made of a flexible material, preferably, for example, rubber, and has a through-passage opening 19 which is positioned such that, in the closed state, the dispensing openings 20 of the components 16 and the through-passage opening 19 of the valve plate 18 are not located one above the other.
  • the valve plate 18 here is fastened on the component 16 by way of its outer border.
  • valve plate 18 If the pressure in the interior of the container is increased, then the valve plate 18 is raised and releases the through-passage for the substance which is to be dispensed from the interior of the container, in that it is possible for this substance, in the first instance, to flow through the dispensing openings 20 and then to flow along between the valve plates 18 and the component 16 as far as the through-passage opening 19 , and to pass out through the latter.
  • the valve plate 18 may be fastened in different ways on the component 16 ; only a few examples are mentioned hereinbelow.
  • the border of the valve plate 18 may be adhesively bonded to the component 16 , or it can be positioned in a corresponding milled recess in the component 16 , in which case additional adhesive bonding is advantageous here too, and as an alternative, or in addition, the valve plate 18 may be fixed on the component 16 by corresponding retaining rings.
  • the valve plate 18 it is possible for the valve plate 18 to be produced in a single piece with the component 16 by multi-component injection molding.
  • a further variant is to configure the lips of the air-admission valve 11 and the valve plate 18 in one piece by producing this single-piece component by injection molding, in which case it is molded, in part, in corresponding cutouts in the component 16 .
  • Dispensing devices may comprise the valve systems described herein according to an embodiment of the invention to be integrated with special applicators.
  • the inventive valve system or one of its embodiments is/are designed such that it is not possible for a product, once dispensed, to flow back from the applicator surface into the container. They are thus suitable for containers for free-flowing substances of all types, but, in addition, provide great advantages for containers which are envisaged for dispensing easily perishable substances or which have to satisfy stringent hygiene-related requirements.
  • Applicators for shoe creams or other cleaning and treating/preserving substances in particular those with a brush or a sponge and the container for cleaning clothing
  • the valve system is also highly suitable for the conventional container closures and applicators, including, for example, containers for substances for washing and body care (shampoo, shower gel, suntan milk, body-care lotion, etc.).
  • containers for substances for washing and body care shampoo, shower gel, suntan milk, body-care lotion, etc.
  • the amount of preserving and stabilizing substances can be reduced to a considerable extent.
  • the contents do not become cloudy, which in many cases is regarded as detracting from quality.
  • a further application for the inventive valve system is in the food sector, for example for jam, honey, ketchup and mayonnaise, mustard, sauces and the like.
  • Such a configuration of the closure reduces the loss of easily volatile substances such as perfume, alcohol, essential oils, etc., even if the lid is not closed carefully or in the case of the container being configured without a hinged lid.
