Definitions

  • the invention relates to a foam dispenser.
  • a foam dispenser This includes a plastic bottle made of 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 which is arranged in the chamber, the foam generating device being arranged in or connected to the closure cap, and a riser pipe which is arranged inside the bottle and connected to an inlet.
  • Disinfectants or cleaning agents are often alcoholic solutions, since alcohols have good microbiocidal effectiveness, depending on the chain length. Such agents are offered as a solution, gel or foam. Alcoholic solutions are difficult to foam because alcohol is a defoaming agent. Foaming of alcohol-based products is used to create foam in hand-operated dispensers or automatic dispensers a foam generating device is used, which ensures that a foam is produced when the liquid and air are mixed.
  • the dispenser systems especially in the case of mechanical dispensers, often consist of a large number of sensitive components and are therefore complex to produce and more expensive.
  • GB 1 478 607 A describes a hand-operated apparatus for making and dispensing foam with a siphon-type bottle.
  • a rigid porous body is placed in the bottle in which liquid and air are mixed.
  • the air flow is regulated by a valve.
  • 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 produced inexpensively with few components and enables alcoholic solutions to be foamed.
  • the foam body consists of an open-cell foam and the open-cell foam in the chamber has a density of more than 0.03 g/cm 3 . Density is determined by measuring the outside dimensions of the foam body, determining the weight of the foam body and calculation of the density from weight and volume. The measurement or determination of the outer dimensions of the foam body is based on its dimensions in the chamber.
  • foam body means 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 of the invention is a manual foam dispenser which is hand-operated, i.e. the foam is generated by squeezing the bottle with the hand.
  • the plastic bottle is therefore formed from a flexible plastic so that it can be squeezed.
  • the plastic bottle is preferably made of polypropylene (PP), polyethylene terephthalate (PET), soft polyethylene (Low Density Polyethylene, LDPE), hard polyethylene (High Density Polyethylene, HDPE) or a mixture thereof, particularly preferably of HDPE and LDPE.
  • the foam dispenser of the invention preferably contains an alcoholic or non-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 is a silicone surfactant.
  • the surfactant or the surface-active substance is preferably contained in the mixture in an amount of 0.2 to 5% by weight, particularly preferably 0.2 to 2.5% by weight.
  • the foam dispenser according to the invention can be used for cleaning agents for skin and hands, for surfaces or instruments, or for disinfectants for skin or hands, for surfaces or instruments, for wound cleaning agents or wound disinfectants, or for cosmetics, such as hair or skin cleaning agents or hair or skin care products be used.
  • an alcoholic composition In order to foam an alcoholic composition, it must be mixed with foamable substances, ie surfactants or surface-active substances. Alcohols disrupt surface tension and are also used as defoamers.
  • foamable substances ie surfactants or surface-active substances. Alcohols disrupt surface tension and are also used as defoamers.
  • 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 produce foam, are therefore required for the foam formation of an alcohol-containing composition.
  • 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 has a density greater 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. 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 preferably 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 at most 0.06 g/cm 3 .
  • the cell count is preferably determined microscopically.
  • the foam In the uncompressed state, the foam preferably has an average pore size of from 0.3 mm to 0.9 mm, measured according to ASTM D 3576-2004, preferably from 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, particularly preferably by 15% to 50%, particularly preferably by 35% to 50% and very particularly preferably by 35% to 40%. Compression increases the density of the foam and can also change the shape of the pores in the foam. Both the increase in density and the change in shape can make the solution more foamable.
  • the chamber can 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 fill the volume of the chamber preferably at least 80%, more preferably at least 85%, even more preferably at least 90%, particularly preferably at least 95% and in particular essentially 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 means that the liquid has to flow through the pores of the foam and the foam body is prevented from floating on the liquid.
  • the foam body is particularly preferably in full contact with the side walls of the chamber, so that the liquid has to flow through the foam when flowing through the chamber and no liquid can flow past the foam body.
  • the foam body has the same cross-section as the chamber.
  • the foam body preferably has a height which corresponds to at least half the length of the chamber, since a particularly good foam is produced when liquid and air have a sufficient distance in which they can mix in the pores of the foam.
  • the chamber is at least partially cylindrical and the foam body is cylindrical.
  • the chamber contains a plurality of foam bodies, these may be shaped as sections of a cylinder, such as two half-cylinders, or as pie slices, again having the overall shape of a cylinder.
  • all foam bodies preferably consist of the same foam material. This has the advantage that the production of the foam dispenser is simpler and more economical since different materials do not have to be kept on hand. In addition, the same mixing effect is achieved in all areas and a uniform foam is produced if the foam bodies are made of the same material.
  • the chamber which is preferably at least partially cylindrical, preferably has a chamber floor and at least one chamber wall that extends from the chamber floor in the direction of the top of the closure cap, with at least one inlet being arranged in the chamber floor and at least one inlet being arranged in a chamber wall.
  • the chamber floor 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 pipe and, when used overhead, preferably forms the inlet for air.
  • An air chamber, from which the air flows through the inlet into the chamber, can be arranged in a connecting piece between the end of the riser pipe and the inlet.
  • 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, the Inlets are preferably evenly spaced and preferably provide the inlet for liquid when used overhead.
  • the air inlet is the inlet which, in use, connects to an air reservoir in the bottle.
  • the liquid inlet is the inlet which, in use, is connected to a liquid reservoir.
  • the riser which is arranged inside the bottle, is preferably connected to an inlet in the bottom of the chamber and preferably forms the inlet for air.
  • 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 are arranged concentrically to one another in the overlapping area and are preferably arranged offset relative to their longitudinal axis or have different lengths, so that the area on the chamber floor has only one wall.
  • the foam body is placed in the inner cylinder.
  • the inlets in the side wall of the chamber are preferably located only in the outer cylinder, more preferably only in the lower, non-double-walled part of the chamber.
  • the inner hollow cylinder can be connected to the closure cap and e.g. be formed in one piece with the closure cap.
  • the embodiment of the chamber as a double-walled hollow cylinder is particularly advantageous because the liquid flow is guided by the double-walled cylinder.
  • the liquid first gets into the outer of the two hollow cylinders and thus into the foam-free area and is then transported to the lower opening of the inner hollow cylinder.
  • it flows into the foam body from below, so that the entire length of the foam body can be used to produce foam.
  • the foam dispenser is easier to assemble, since the foam body is already in position when screwing or clamping the closure cap and does not have to be fixed first during the screwing or clamping process. It is also easily possible to replace the foam body by replacing only the inner cylinder of the chamber or the cap connected to the inner cylinder.
  • the foam dispenser according to the invention can be used to generate foam either upside down, ie with the bottle turned upside down with the bottle bottom pointing upwards, or upright, with the bottle bottom pointing downwards.
  • Up means vertically up to the ceiling and down means vertically down to the floor.
  • the bottle can also be held at a slight angle during use, this is also included in upside down and upright.
  • the foam body made of open-cell foam is located inside the chamber, which has cavities in which air and liquid are mixed with one another and a foam is thereby produced.
  • a portion of the chamber in which at least one inlet is located is empty and does not contain a foam body. Air and liquid are preferably already partially mixed after entering the chamber before they are transported premixed into the foam body.
  • the foam generation occurs as follows:
  • the chamber with the foam body has one or more inlets which are below the liquid level inside the bottle in the upside down position.
  • the riser tube is at the top of the chamber when the bottle is inverted and terminates in the headspace of the bottle above the liquid level.
  • the air is pushed down through the riser tube.
  • the liquid is sucked out of 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 a foam.
  • foam generation occurs as follows:
  • the chamber with the foam body has one or more inlets that are above the liquid level inside the bottle.
  • the riser which is in the upright position at the bottom of the chamber, extends to the bottom of the bottle.
  • the liquid is pushed upwards through the riser pipe, with the different pressure conditions during this process causing the air to be sucked in from the headspace of the bottle. Air and liquid are mixed together in the pores of the open-cell foam and the foam thus produced is discharged upwards from the outlet opening.
  • the opening for the foam outlet is not directed vertically upwards, but rather the foam is discharged via a spout running in a lateral direction.
  • the bottle is preferably of a size that is easy to hold with one hand.
  • the bottle has, for example, a volume of 50 ml to 500 ml.
  • the bottle preferably has a volume of 100 ml to 250 ml, in particular 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 inlet opening(s) for air to the size of the inlet opening(s) for liquid is preferably 1:0.9 to 1:1.5, particularly preferably 1:0.9 to 1:1.1.
  • foaming works both upside down and upright.
  • the ratio of the overall size of air inlets and liquid inlets has an impact on foam formation.
  • the diameter of the air inlet opening must not be too large and the proportion of air must not be too high, otherwise good foam will not form.
  • the foam generating device is designed as an insert with a flange.
  • the flange is placed on the top edge of the bottle neck, with the cap being attached to the neck of the bottle and fixing the liner.
  • closure cap and foam-generating device are designed in one piece and the closure cap with the foam-generating device is attached to the neck of the bottle, preferably screwed on or crimped.
  • the foam-generating device is designed as an insert which snaps into the closure cap, is glued to the closure cap or welded to the closure cap, the closure cap being attached to the insert on a neck of the bottle, preferably being screwed on or crimped.
  • the closure cap can have a conventional design and can include a hinged lid or a protective cap, for example, or be designed as a pull-type closure. She also usually has a fastening device by which it is attached to the neck of the bottle, eg a screw thread or a snap-on cap.
  • 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 or non-alcoholic solution can be refillable and/or the foam body can be exchangeable.
  • the foam dispenser according to the invention can be produced inexpensively since it is made up of only a few components. Thanks to the foam generating device, foam can also be generated with alcoholic solutions and when used upside down as well as upright.
  • the foam is generated according to the invention with a hand-operated foam dispenser with few components. Due to the compact design without a motor, electrical parts or valves for regulation, cost-effective production is possible and easy, intuitive and trouble-free handling is provided.
  • An alcoholic disinfectant can be applied as a foam with the foam dispenser according to the invention. Due to its consistency, foam has the advantage over liquids that it can be better dosed and distributed. For example, while a liquid hand disinfectant flows quickly from the hand when it is removed and therefore not only gets on the hand but also on the floor, the foam flows more slowly and can be distributed more easily and drip-free on the hands.
  • the subject matter of the invention is also the use of a foam dispenser according to the invention for foaming an alcoholic solution, preferably an alcoholic disinfectant.
  • the outer dimensions of a foam sample are first measured and the volume is calculated from the outer dimensions.
  • the density of the uncompressed foam is thus determined according to ISO 845 (g/cm 3 ) or ASTM D 3574-11A (lb/ft 3 ) standards. If the foam body is compressed in the foam dispenser chamber, the density increases accordingly by the degree of compression. In order to calculate the density, reference is then made here to the volume which the foam body has in the chamber in the compressed state.
  • the number of pores is determined microscopically. To do this, a straight line is drawn on one surface of the foam and the number of pores is counted over a distance of 1 inch along this distance.
  • the pore size is determined according to ASTM D 3576-2004. For this purpose, a thin layer of a defined size is cut from 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.
