Definitions

  • the present invention concerns a cleaning system comprising a sprayer bottle and a cleaning composition.
  • Cleaning systems comprising sprayer bottles provided with a sprayer assembly and used for cleaning domestic surfaces have been known for decades and are available in many forms and use various cleaning compositions.
  • Sprayer bottles represent the most recognisable packaging for spray cleaning products, regardless of whether they are for residential or industrial use. They comprise a bottle and a sprayer assembly.
  • the bottles are sold by numerous distributors and are usually produced by blow moulding in HDPE, in polypropylene or PET, transparent or opaque, and comprise a label.
  • the label is usually obtained with the in-mould method, by screen printing, from paper / laminate die-cut and glued or heat-shrink plastic or by means of a combination of these methods.
  • the bottle is almost always disposable and non-reusable and for this reason many sprayer assemblies are irreversibly attached to the bottle opening, thus making re-use of the bottle impossible.
  • the cleaning compositions used differ greatly from one another and include concentrated or diluted solutions, for example for the specific cleaning of kitchens or bathrooms.
  • Sprayer bottles comprising detergents that emulsify air and form foams which collapse after a short time are also known.
  • the cleaning compositions must ensure maximum cleaning effect.
  • research efforts have concentrated on how to vary the type and quantity of the various elements that make up the cleaning composition to obtain maximum cleaning effect without ruining the surface being cleaned.
  • the cleaning compositions for cleaning the house can be liquid or also in the form of gel, but generally the compositions used inside the sprayer bottles are liquid.
  • Sprayer bottles which spray in a down-up direction has also been proposed to solve said problem.
  • Sprayer bottles of this type are available on the market, but they do not solve the problem of cleaning surfaces on which the product does not remain long enough, for example vertical smooth surfaces or the lower part of the edge of the WC.
  • the majority of the sprayer assemblies comprise a valve which operates to close the intake of the priming tube and simultaneously open an inlet for the liquid on the bottom of the sprayer when the bottle is inverted.
  • cleaning compositions in the form of gel are used to ensure that the cleaning composition remains longer in contact with the surface to be cleaned.
  • EP1103308 shows a sprayer comprising an outlet orifice for a liquid and a chamber into which the outlet orifice leads.
  • the chamber is delimited laterally by an annular wall.
  • the annular wall does not have any openings.
  • EP0709143 shows a sprayer comprising an outlet orifice for a liquid and a chamber into which the outlet orifice leads.
  • the chamber is part of a dual chamber foam generation device not otherwise defined and appears to be added to the outside of the sprayer.
  • JP08299865 describes a bottle provided with a sprayer assembly comprising an orifice communicating with a first chamber.
  • the first chamber is located inside an outer chamber.
  • EP24333 shows a sprayer assembly comprising an orifice.
  • the orifice can be closed with a closing device 60 which can form a chamber around the orifice and this chamber is provided with openings.
  • the object of the invention is a cleaning system which is able to solve the problems described above and which in particular also effectively cleans surfaces which are difficult to reach or difficult to clean.
  • a cleaning system comprising a sprayer bottle 1 comprising a bottle 2, a sprayer assembly 3 and a liquid cleaning composition contained inside the bottle.
  • the sprayer assembly 3 is manually operable to expel the liquid cleaning composition by means of a spray which forms a foam.
  • the foam occupies a volume equal to at least 15 times the volume of liquid cleaning composition sprayed and, 30 seconds after spraying, the foam occupies a second volume equal to at least 50% of the first volume.
  • the foam obtained is compact and therefore does not collapse and remains on the surface at length, in particular on vertical surfaces, and is furthermore easy to remove.
  • the second volume is equal to at least 75% of the first volume.
  • the second volume is equal to at least 90% of the first volume. Even more preferably, the second volume is equal to at least 95% of the first volume.
  • the first volume is equal to at least 20 times the volume of liquid cleaning composition sprayed.
  • the first volume is equal to at least 25 times the volume of liquid cleaning composition sprayed.
  • the cleaning system of the present invention has proved to be particularly suitable for cleaning domestic surfaces, in particular for cleaning bathrooms, tiles and in any case particularly suitable for cleaning vertical and/or slippery surfaces.
  • the cleaning system of the present invention has also proved particularly suitable for cleaning plastic food containers, porcelain cups and fabrics.
  • Figure 1 illustrates a sprayer bottle 1 comprising a bottle 2 and a sprayer assembly 3.
  • the bottle 2 can have different shapes and is preferably made of thermoplastic material, for example HDPE, and is preferably obtained by blow moulding.
  • the bottle 2 comprises, as typically occurs in the conventional sprayer bottles, a lower region 4 to house the cleaning composition and an upper region 5, also called grip or neck, having a diameter section smaller than the lower region 4.
  • the upper region 5 has an upper opening 6 comprising a fastening portion 7 for fastening the sprayer assembly.
  • the upper opening 6 is preferably circular as in the embodiment illustrated in the figures and preferably has a diameter smaller than the upper region 5.
  • the upper opening 6 of the bottle 2 can preferably have a diameter ranging from 0.5 cm to 3 cm.
  • the fastening portion 7 is preferably threaded as in the embodiment illustrated in the figures, but alternatively can also allow fastening by bayonet, by ramp, with tabs or similar known means that accept finishes complementary to those present in a corresponding fastening portion present on the sprayer assembly 3 so as to allow the removable or non-removable fastening of said sprayer assembly.
  • Simple threads are commonly used as means for fastening a sprayer assembly 3 to a bottle 2 and said threads are preferred.
  • the sprayer assembly 3 can also be irreversibly fastened on the neck of the bottle, preventing the collar from rotating in the reverse direction, for example by means of locking teeth.
  • the sprayer assembly 3 is locked on the bottle 2 by means of a bayonet device, as is known in the art.
  • Bayonet connectors of this type are described for example in the patent US7478739 .
  • the upper region 5 or neck of the bottle 2 can have very different shapes and, for example, can also be an angled neck or have a duck-neck shape to facilitate spraying in difficult situations and against surfaces that are difficult to reach.
  • the upper region 5 of the bottle 2 can also be shaped so as to have recesses for positioning the user's fingers to facilitate gripping of the bottle by the user.
  • the upper region 5 has a diameter section smaller than the lower region 4 as in the embodiment illustrated in the figures, but coaxial with the lower region and serving essentially to allow optimal gripping of the bottle.
  • the upper region of the bottle has a more restricted diameter but is inclined with respect to the vertical so as to facilitate spraying on surfaces that are difficult to reach.
  • the bottle comprises a bottle body 8, which preferably has a parallelepipedal section with rounded vertexes.
  • This approximately parallelepipedal section is maintained also in the upper region where the bottle body 8 narrows.
  • bottle body 8 can also have a very different shape and also present a combination of different shapes.
  • the volume of cleaning composition contained in the bottle generally ranges from 250 ml to 2 litres, more preferably from 500 ml to 1000 ml, for example 750 ml.
  • the sprayer assemblies are generally designed to spray in a controlled direction with a relatively compact jet. Examples of sprayer assemblies are described in the patent US4527741 .
  • the sprayer assembly 2 When the sprayer assembly 3 is coupled to the bottle 2 as in figure 1 , the sprayer assembly 2 will be substantially horizontal and the spray coming from the sprayer assembly 2 will be generally horizontal.
  • the spray coming from the sprayer assembly will preferably have a conical shape.
  • the form of the spray can be flat, pyramidal or also in the form of a narrow jet stream.
  • the sprayer assembly 3 shown in section in figure 2 and in perspective in figure 3 comprises a sprayer body 10 comprising a seat 11 engaged by a priming tube 13, which extends inside the bottle 2 and through which, in use, the cleaning fluid or composition to be sprayed flows.
  • the sprayer body 10 supports a piston mechanism 14 operated by a trigger 15 or lever, which moves along a forward stroke under the manual action of a user and along a return stroke under the action of elastic means when said manual action ceases.
  • the piston mechanism 14 is of known type and not described in detail and is configured so as to suck liquid from the priming tube through the upper end 16 of the seat into a chamber 17, when the trigger 15 performs the return stroke, so as to prevent reflux of the liquid sucked into the priming tube 13, and compress it towards an outlet channel 18 when the trigger performs the forward stroke, compressing the liquid to a pressure value greater than 2 bar, preferably greater than 2.5 bar, even more preferably between 2 and 5 bar, for example 3 bar, and is adapted to compress a valve 33 which, when a predetermined pressure is reached, allows the opening of an inlet orifice 34 into a supply channel 18.
  • the supply channel 18 communicates via a distribution chamber with an outlet orifice 22.
  • the supply channel 18 is therefore not in line with the outlet orifice 22; the liquid reaches the outlet orifice only via an annular distribution chamber.
  • the nozzle 20 comprises a rear connecting portion 21 in particular of truncated pyramid shape mounted on the sprayer body 10 at the end of the outlet channel 18.
  • the nozzle 20 comprises an outlet orifice 22 through which the cleaning composition can flow to the outside, forming a spray.
  • the nozzle 20 is generally rotatable between a first STOP position in which the passage of the cleaning composition from the outlet channel to the outlet orifice is blocked and a second position in which the spray is allowed.
  • the nozzle 20 further comprises a front terminal portion 24 which defines a chamber 25 into which the outlet orifice 22 leads.
  • the chamber 25 is laterally delimited by an annular wall 26 which is coaxial with the outlet orifice 22 and which protrudes from the rear portion 21.
  • annular wall 26 is a circular collar.
  • a front end 27 of the chamber is completely open and the rear end 28 of the chamber is delimited by a rear wall 28 in which the outlet orifice 22 is provided.
  • this wall 28 has an annular groove 29 which extends around the outlet of the outlet orifice 22.
  • the annular wall 26 has at least one opening 30, preferably a first 30 and a second 31 opening for the passage of air.
