Definitions

  • the invention relates to a foam dispenser.
  • a plastic bottle made of a flexible plastic with a bottle opening, a closure cap that closes the bottle opening and has a dispensing opening for a foam
  • a foam-generating device for foaming a solution comprising a chamber with at least one wall, at least one inlet for air in a wall of the chamber and at least one inlet for liquid in a wall of the chamber, and at least one foam body arranged in the chamber, wherein the foam-generating device is arranged in the closure cap or connected thereto, and a riser tube arranged inside the bottle and connected to an inlet.
  • Disinfectants and cleaning agents are often alcoholic solutions, as alcohols have good microbicidal efficacy depending on their chain length. Such agents are offered as solutions, gels, or foams. Alcoholic solutions are difficult to foam because alcohol is a defoamer. To generate foam in manually operated or mechanical dispensers, a foam generation device is used to foam alcohol-based products. This device ensures that foam is created when the liquid and air mix.
  • the dispensing systems especially in the case of mechanical dispensers, often consist of numerous delicate components and are therefore complex to manufacture and expensive.
  • GB 1 478 607 A Describes a hand-operated device for producing and dispensing foam using a bottle with a dip tube.
  • the bottle contains a rigid, porous body in which liquid and air are mixed.
  • the air flow is regulated by a valve.
  • US 4,018,364 A Describes a hand-operated foam dispenser with a bottle and a foam generating device.
  • the foam generating device has a self-supporting porous element made of rigid material for foam generation.
  • EP 1 428 580 A1 discloses a portable dispenser for foam or mist.
  • the dispenser features a 3D body in the outlet area that creates turbulence in the liquid, resulting in foaming or misting.
  • a foam dispenser is known that has a flexible container with an inserted foam generating device.
  • a porous material is arranged in the foam generating device, which is used to foam a non-alcoholic cleaning fluid.
  • the object of the invention is to provide a hand-operated foam dispenser that overcomes the disadvantages known from the prior art and, in particular, can be manufactured cost-effectively with few components and enables the foaming of alcoholic solutions.
  • foam body is understood to mean at least one foam body, i.e. when a foam body is described, exactly one foam body or several foam bodies are included.
  • the foam dispenser according to the invention is a manual foam dispenser that is hand-operated, i.e., the foam is generated by squeezing the bottle by hand.
  • the plastic bottle is therefore made of a flexible plastic so that it can be compressed.
  • the plastic bottle is preferably made of polypropylene (PP), polyethylene terephthalate (PET), low-density polyethylene (LDPE), high-density polyethylene (HDPE), or a mixture thereof, particularly preferably HDPE and LDPE.
  • the foam dispenser according to the invention preferably contains an alcoholic mixture, which is typically a solution.
  • the mixture contains at least one surfactant or surface-active substance that acts as a foamable substance.
  • the surfactant or surface-active substance is preferably present in the mixture in an amount of 0.2 to 5 wt.%, particularly preferably 0.2 to 2.5 wt.%.
  • the foam dispenser according to the invention can be used for disinfectants for skin or hands, for surfaces or instruments, or for wound disinfectants.
  • the monohydric alcohol having 1 to 4 carbon atoms is preferably selected from methanol, ethanol, 1-propanol, 2-propanol, butanol, and a mixture thereof.
  • the monohydric alcohol is preferably ethanol.
  • the at least one surfactant in a highly alcoholic solution is preferably a silicone surfactant.
  • the silicone surfactant is preferably a water-soluble silicone surfactant; more preferably, the water-soluble silicone surfactant(s) is/are a bis-PEG/PPG-X/Y-polydimethylsiloxane or an alkyl-PEG/PPG-X/Y-polydimethylsiloxane, where X describes the chain length of the ethoxyl units (PEG) and Y the chain length of the propoxyl (PPG) units, and X and Y independently of one another are preferably 14-25.
  • X is Y.
  • Polydimethylsiloxanes are silicon-based polymers used in cosmetics under the name dimethicone (INN).
  • Suitable silicone surfactants are, for example, BIS-PEG/PPG-14/14 Dimethicone or Bis-PEG/PPG-20/20 Dimethicone, which is available under the trade name Abil B 8832.
  • excipients used include skin care substances, lipid replenishers, humectants, pH regulators, dyes, fragrances or mixtures thereof.
  • foaming an alcohol-containing composition therefore requires appropriate chemical auxiliaries and additional physical/mechanical means, such as a foam dispenser, which, according to the invention, has a chamber with at least one foam body in which liquid and air can be mixed to generate foam.
  • foamable substances i.e., surfactants or surface-active substances. Alcohols disrupt surface tension and are also used as defoamers. Foaming an alcohol-containing composition therefore requires appropriate chemical auxiliaries and additional physical/mechanical means, such as a foam dispenser, which, according to the invention, has a chamber with at least one foam body in which liquid and air can be mixed to generate foam.
  • the open-cell foam preferably consists of a polymeric material, particularly preferably polyurethane (PUR) or acrylonitrile butadiene rubber, also known as nitrile butadiene rubber (NBR).
  • PUR polyurethane
  • NBR nitrile butadiene rubber
  • the open-cell foam in the chamber preferably has a density of more than 0.03 g/cm 3.
  • the density refers to the density of the foam body placed in the chamber, which can be uncompressed or compressed.
  • the density is determined by measuring the external dimensions of the foam body, determining the weight of the foam body and calculating the density from the weight and volume. When measuring or determining the external dimensions of the foam body, its dimensions in the chamber are taken into account. For an uncompressed foam body, the density of the uncompressed foam in the chamber is given. For a compressed foam body, the density of the compressed foam in the chamber is given.
  • the foam placed in the chamber has a density of at least 0.035 g/cm 3 , particularly preferably at least 0.045 g/cm 3 . More preferably, the foam placed in the chamber has a density of at most 0.08 g/cm 3 , preferably at most 0.06 g/cm 3 . The foam in the chamber preferably has a density of more than 0.03 g/cm 3 and of at most 0.06 g/cm 3 .
  • the cell count is preferably determined microscopically.
  • the foam preferably has an average pore size of 0.3 mm to 0.9 mm in the uncompressed state, measured according to ASTM D 3576-2004, preferably 0.4 mm to 0.8 mm.
  • the foam body is compressed in the chamber, with the foam body preferably being compressed by 10% to 50% of the volume of the uncompressed body, more preferably by 15% to 50%, more preferably by 35% to 50%, and most preferably by 35% to 40%.
  • the compression increases the density of the foam and can also change the shape of the foam's pores. Both the increase in density and the change in shape can improve the foaming of the solution.
  • the chamber can, for example, have a volume of 1 cm 3 to 5 cm 3 , preferably 1 cm 3 to 3 cm 3 and particularly preferably 1 cm 3 to 2 cm 3 .
  • the chamber has a volume of 1.4 cm 3 to 2 cm 3 .
  • the foam body or the total number of foam bodies preferably fill the volume of the chamber to at least 80%, more preferably to at least 85%, even more preferably to at least 90%, particularly preferably to at least 95% and in particular substantially completely.
  • the foam body is preferably fixed to the wall of the chamber, preferably by being clamped in position in the chamber by contact with the wall. This ensures that the liquid must flow through the pores of the foam and prevents the foam body from floating on the liquid.
  • the foam body particularly preferably lies completely against the side walls of the chamber, so that the liquid must flow through the foam when flowing through the chamber and no liquid can flow past the foam body. In this case, the foam body has the same cross-section as the chamber.
  • the foam body preferably has a height that corresponds to at least half the length of the chamber, since a particularly good Foam is created when liquid and air have a sufficient distance to travel to mix in the pores of the foam.
  • the chamber is at least partially cylindrical, and the foam body is cylindrical. If the chamber contains multiple foam bodies, these can be shaped, for example, as sections of a cylinder, e.g., as two half-cylinders or as pie slices that, as a whole, again have the shape of a cylinder.
  • the chamber which is at least partially cylindrical, has a chamber bottom and at least one chamber wall extending from the chamber bottom toward the top of the closure cap, with at least one inlet arranged in the chamber bottom and at least one inlet arranged in a chamber wall. If the chamber bottom is circular, the chamber has a curved chamber wall.
  • the chamber has only a single inlet in the chamber floor, which is connected to the riser tube and preferably forms the air inlet when used overhead.
  • An air chamber can be arranged in a connecting piece between the end of the riser tube and the inlet, from which the air flows through the inlet into the chamber.
  • the chamber preferably has at least two, preferably three to six, particularly preferably three or four inlets in the chamber wall or the side wall of the chamber, wherein the inlets are preferably arranged at equal distances from one another and, when used upside down, preferably form the inlet for liquid.
  • the air inlet is the inlet that, during use, is connected to an air reservoir in the bottle.
  • the liquid inlet is the inlet that, during use, is connected to a liquid reservoir.
  • the riser tube located inside the bottle is preferably connected to an inlet in the bottom of the chamber and preferably forms the air inlet.
  • the chamber is at least partially designed as a double-walled hollow cylinder.
  • the double-walled hollow cylinder has an inner and an outer cylinder, which Overlap areas are arranged concentrically to one another and are preferably offset relative to their longitudinal axis or have different lengths, so that the area at the chamber bottom has only a single wall.
  • the foam body is arranged in the inner cylinder.
  • the inlets in the side wall of the chamber are preferably arranged only in the outer cylinder, particularly preferably only in the lower, non-double-walled part of the chamber.
  • the inner hollow cylinder can be connected to the closure cap and, for example, be formed integrally with the closure cap.
  • the design of the chamber as a double-walled hollow cylinder is particularly advantageous because the double-walled cylinder directs the liquid flow.
  • the liquid first enters the outer of the two hollow cylinders and thus the foam-free area and is then transported to the lower opening of the inner hollow cylinder. This causes it to flow from below into the foam body, so that the entire length of the foam body can be used to generate foam.
  • the foam dispenser is easier to assemble because when the closure cap is screwed or clamped on, the foam body is already in position and does not have to be secured during the screwing or clamping process. It is also easy to replace the foam body by just replacing the inner cylinder of the chamber or the closure cap connected to the inner cylinder.
  • the foam dispenser according to the invention can be used to generate foam either upside down, i.e., with the bottle upside down and the bottom facing upwards, or upright, with the bottom facing downwards.
  • "Up” means pointing vertically upwards toward the ceiling
  • “down” means pointing vertically downwards toward the floor.
  • the bottle can also be held at a slight angle during use; this also includes upside down and upright positions.
  • the foam body is made of open-cell foam within the chamber. This foam body has cavities in which air and liquid are mixed together, thereby creating a foam.
  • a part of the chamber is provided with at least one inlet. It is empty and contains no foam core. Air and liquid are preferably partially mixed upon entering the chamber before being transported premixed into the foam core.
  • foam is generated as follows:
  • the chamber with the foam body has one or more inlets which, when the bottle is inverted, are below the liquid level inside the bottle.
  • the riser tube is located at the top of the chamber and ends in the air space inside the bottle above the liquid level.
  • the different pressure conditions during this process suck the liquid from the bottle through the inlets into the chamber. Air and liquid are mixed in the pores of the open-cell foam, and the foam is discharged downwards through the outlet opening as foam.
  • foam generation occurs as follows:
  • the chamber containing the foam body has one or more inlets located above the liquid level inside the bottle.
  • the riser tube which is located at the bottom of the chamber when in the upright position, reaches the bottom of the bottle.
  • the varying pressure conditions during this process cause air to be drawn in from the headspace of the bottle. Air and liquid are mixed in the pores of the open-cell foam, and the resulting foam is expelled upward through the outlet opening.
  • the opening for the foam outlet is not directed vertically upwards, but the foam is released via a spout with a direction in a lateral direction.
  • the bottle should preferably be sized to be easy to hold with one hand.
  • the bottle should have a volume of 50 ml to 500 ml.
  • the bottle should preferably have a volume of 100 ml to 250 ml, especially 100 ml to 150 ml.
  • the air inlet preferably has a diameter of 1.0 mm to 1.4 mm.
  • the liquid inlet preferably has a diameter of 0.6 mm to 0.8 mm.
  • the ratio of the size of the air inlet(s) to the size of the liquid inlet(s) is preferably 1:0.9 to 1:1.5, particularly preferably 1:0.9 to 1:1.1. With a ratio of the size of the air inlets to the liquid inlets of approximately 1:1, as in the last-mentioned preferred embodiment, foam formation works both upside down and upright.
  • the ratio of the total size of the air inlets to the liquid inlets influences foam formation.
  • the diameter of the air inlet opening must not be too large, nor must the air content be too high; otherwise, good foam will not be formed.
  • the foam generating device is designed as an insert with a flange.
  • the flange is placed on the upper edge of the bottle neck, with the cap attached to the neck of the bottle and securing the insert.
  • the closure cap and foam generating device are formed as a single piece, and the closure cap with the foam generating device is attached to the neck of the bottle, preferably screwed or crimped.
  • the foam generating device is designed as an insert that is snapped into the closure cap, glued to the closure cap, or welded to the closure cap, wherein the closure cap is attached to the insert to a neck of the bottle, preferably screwed or crimped.
  • the closure cap can have a conventional design, such as a flip-top lid or a protective cap, or be designed as a pull-lock closure. It also typically has a fastening device to attach it to the neck of the bottle, such as a screw thread or a snap-on closure.
  • the foam dispenser according to the invention can be designed as a disposable product for disposal after the liquid has been emptied, or as a refillable, reusable product.
  • the alcoholic solution can be refillable and/or the foam body can be replaceable.
  • the foam dispenser according to the invention can be manufactured cost-effectively because it is composed of only a few components.
  • the foam generation device enables foam generation even with alcoholic solutions and both upside down and upright.
  • foam generation is achieved with a hand-operated foam dispenser with few components. Due to the compact design without a motor, electrical parts, or valves for control, cost-effective production is possible and easy, intuitive, and trouble-free handling is ensured.
  • Disinfectant can be applied as foam using the foam dispenser according to the invention. Due to its consistency, foam has the advantage over liquids that it is easier to dose and distribute. While liquid hand disinfectant, for example, flows quickly from the hand when dispensed, thus spilling not only onto the hand but also onto the floor, foam flows more slowly and is therefore easier to distribute on the hands without dripping.
  • the external dimensions of a foam sample are first measured and the volume is calculated from the external dimensions.
  • the density of the uncompressed foam is thus determined according to the standards ISO 845 (g/cm 3 ) or ASTM D 357411A (lb/ft 3 ). If the foam body is compressed in the chamber of the foam dispenser, the density increases accordingly by the degree of compression. To calculate the density, reference is then made to the volume that the foam body has in the chamber in its compressed state.
  • the number of pores is determined microscopically. A straight line is drawn across the surface of the foam, and the number of pores along this line is counted over a distance of 1 inch.
  • the pore size is determined according to ASTM D 3576-2004. For this purpose, a thin layer of a defined size is cut from a foam and placed in a special projector. The projector projects the sample along with a reference line. The length of the reference line is given in millimeters. The number of cells intersected by the reference line is counted. The mean pore size is calculated from the length of the reference line and the number of pores.
