Definitions

  • This invention relates to bags for use in storing granular detergent, wherein the bag has a re-closing means and the product comprises particles of a specific size.
  • Flexible bags are used today to package a wide variety of consumer products including granular detergents. In order to be useful as a package these bags must be resistant to opening during sipping and handling at the store. It is also advantageous if the package can be securely reclosable after opening by the consumer and provide protection from product leakage. The ability to re-close the bag is desired by many consumers. This is especially true for bulk size packages.
  • Recloseeble bags according to the preamble of claim 1 are disclosed in EP1409366 . However, it has been found that in some instances methods for re-closing such bags have not been completely satisfactory and the reclosing mean can fail. The present inventor has found that this may be due to contamination of the re-closing means with the contents of the bag, preventing the means from forming a reliable, re-usable seal.
  • the present invention meets the aforementioned needs by providing a reclosable packaging according to claim 1.
  • the product comprises less than 10% by weight of particles having a geometric mean particle diameter of at most 300 micrometers.
  • the product is a detergent composition.
  • FIG. 1 A particularly preferred bag 10 made in accordance with the present invention is illustrated in Figures 1 and 2 .
  • the bag 10 is illustrated having front panel 12, back panel 14, and side panels 16 and 18 with each panel having an upper edge 20 and a lower edge 22.
  • the bag 10 also has a top section 24 and a bottom section 26, which are sealed by joining front panel 12 to back panel 14 along upper edges 20 and lower edges 22.
  • the bag 10 is provided with a line of weakness 28 in each of the front, back and side panels 12, 14, 16, 18.
  • Figure 3 illustrates the bag after the top section 24 has been completely removed, and shows the reclosing means 32.
  • the bags of the present invention are flexible and may be formed from materials including but not limited to polymeric film, woven materials, non-woven materials, preferably polyethylene film, more preferably monolayers, coextrusions, two-layer laminations, three-layer laminations and metalized laminations, all materials with or without lacquer coatings. Bags according to the present invention can be formed by any method known in the art. One method for forming flexible bags from a continuous web of material is well known in the art and described in U.S. Pat. No. 5,054,619 , issued to Muckenfuhs.
  • a continuous web of material 30 shown in Figure 4 is transported in the machine direction, MD, and is provided with a line of weakness 28 across substantially the whole width of the web 30 substantially in the cross-machine direction, CMD, and reclosing means 32 are affixed adjacent to the line of weakness 28 substantially in the cross-machine direction, CMD.
  • the reclosing means 32 shown in Figure 4 comprises one strip of loops 34 and two strips of hooks 36.
  • the bag may be provided via a process as disclosed in patent application EP 1409366 .
  • the main objective of the reclosing means is to protect granular detergents contained in bags from spillage, humidity, and other external factors that might affect the integrity of the product.
  • This re-closing means comprises a mechanical hook and loop or hook and hook type fastener, attached to a flexible bag that allows consumers to open and securely close the bags as many times as product uses in the bag.
  • the means may consist of placing fastening materials on opposite panels of the bag.
  • the panels are the front and back panel although other configurations are contemplated.
  • the fasteners can be either disposable or industrial materials. It is desired to use disposable materials 10 optimize costs.
  • the particular configuration of the re-closing means components should be such that the bag can be sealed throughout the entire use of the product contained therein. By sealed is meant that no product spills out when the bag is tipped on its side.
  • the re-closing means is characterized by the energy required to peel off one component of the fastener from the other component. This energy preferably should not be less than 2.4Kgfmm per each Kg of product contained in the bag.
  • At least one piece of the mechanical fastener may be placed on one panel of the bag while a piece of the matching fastener may be placed on an opposite panel of the bag.
  • one piece of the mechanical fastener is a horizontal strip adhered to the inside of the bag. Most preferably two interacting horizontal strips are adhered to the insides of the bag.
  • the adhesive can be either a hot melt or pressure sensitive adhesive.
  • a hot melt adhesive is applied to the mechanical fastener right before the piece is to be applied to the bag.
  • the pressure sensitive adhesive is adhered to the fastener as one piece.
  • these mechanical fasteners can be accomplished in different ways.
  • One way is to adhere these fasteners to the film before the bag is produced
  • the pieces of mechanical fasteners are attached to the film either while the web of film is being prepared or while the web of film is being unwound from a roll at the machine.
  • the bags may be preformed, and the mechanical fasteners may be adhered to the bag after it has been so formed.
  • the mechanical fastener comprises hooks and loops which are adhered to the flat film.
  • Most preferably one strip of loops and two strips of hooks or one strip of hooks and two strips of loops are applied onto the flat film, in particular, on a part adjacent to the top part of the bag. This allows the closing means to be kept out of the bag length seal while positioning the reclosing means substantially completely around the bag opening to allow the consumer to completely close the bag. This provides significant advantage in terms of roll stability prior to converting the film into a bag if the application process of the reclosing means is separate from the bag forming process, and carried out on different machines.
  • the book-like fastening elements have a height of 1.3 to 3.8 mm.
  • the loop-like fastening elements may a height of 1.5 to 4 mm and/or are larger by 02 to 2.0 mm than the height of said book-like fastening elements.
  • the hook-like fastening elements and lopp-like fastening elements may be provided in a density of 40 to 120 pieces/cm 2 . generally of 60 to 90 pieces/cm 2 .
  • the monofilament generally has a diameter of 0.1 to 0.4 mm, or of 0.14 to 0.25 mm.
  • multifilament yarns consisting of single filaments having a diameter of 20 to 100 ⁇ m, or of 35 to 95 ⁇ m. Such multifilament yarns combine 2 to 50 single filaments, or of 3 to 30 single filaments.
  • the above monofilements and multifilament yarns used for forming hook-like fastening elements and loop-like fastening elements, respectively, comprise synthetic fibers or metal fibers,
  • fibers of thermoplastic resin such as polyamide, polyester, polypropylene and polyethylene are used.
  • polyester is preferred since it exhibits high engaging strength and has high dimensional stability.
  • Thermoplastic resins such as polyamide and polypropylene are also used for preparing plastic projections with a swollen head which constitute hook-tike fastening elements.
  • the synthetic resin constituting it may generally constitute also a multifilament yam used for preparing loop-like fastening elements.
  • Synthetic fibers comprising different resins may however be used separately for hook-like fastening elements and loop-like fastening elements.
  • the resin used for book-like fastening elements preferably has a higher Young's modulus than that used for loop-like fastening elements.
  • synthetic fiber comprising polyester can be used for hook-like fastening elements when synthetic fiber comprising polyamide is used for loop-like fastening elements.
  • the loop materials have a basis weight of less than 40 grams per square metre or even less than 30 gsm.
  • the basis weight of the hook material is less than 200 gsrn.
  • loop materials such N29 supplied by Aplix, France have been found to be particularly effective.
  • low basis weight extruded polypropylene hooks such Aplix 963 supplied by Aplix, France are preferred.
  • the granular detergent product of the invention comprises particles, less than 10% by weight of particles having a geometric mean particle diameter of not greater than 150 micrometers.
  • the word "particles” means the entire size range of the product or the entire size range of discrete particles, agglomerates, or granules in the product. It specifically does not refer to a size fraction (i.e., representing less than 100% of the entire size range) of any of these types of particles unless the size fraction represents 100% of a discrete particle in an admixture of particles.
  • the entire size range of discrete particles of that type have the same or substantially similar composition regardless of whether the particles are in contact with other particles.
  • the agglomerates themselves are considered as discrete particles and each discrete particle may be comprised of a composite of smaller primary particles and binder compositions.
  • geometric mean particle diameter means the geometric mass median diameter of a set of discrete particles as measured by any standard mass-based particle size measurement technique, preferably by dry sieving.
  • the granular product may comprise from 0 to 5%, in particular from 0.1 to 3%, for example from 0.2 to 2% or even at from 1% by weight of undersized particles.
  • Undersized particles are particles having a geometric mean particle diameter of from 0 to 150 micrometers, in particular from 0 to 300 micrometers, for example from 0 to 500 micrometers.
  • the granular product may comprise less than 10%, for example from 0 to 5%, in particular from 0.1 to 3%, for example from 0.2 to 2% or even at from 1% by weight of particles having a geometric mean particle diameter of at most d -1/2 /10 cm, in particular of at most d -1/2 /5 cm, or even of at most d -1/2 /3 cm, for example of at most d -1/2 cm, with d being the average density of hooks and/or loops on a surface of mechanical fastener.
  • the granular product may comprise less than 10%, for example from 0 to 5%, in particular from 0.1 to 3%, for example from 0.2 to 2%, or even at most 1%, by weight of particles having a geometric mean particle diameter of at most Q 1/2 /5 cm, in particular of from 0 to Q 1/2 /2 cm, or even of at most Q 1/2 cm, with Q being the average surface area defined by the inside of the loop.
  • the geometric mean particle diameter of the particles is from 500 microns to 1500 microns, in particular from 600 microns to 1200 microns, and for example from 600 microns to 1000 microns. At least 50%, in particular at least 75%, or even at least 90%, and in particular at least 95%, by weight of the total particles in the product, have the selected mean particle size diameter. In this way, a substantial portion of the granular detergent product will have the uniform size so as to provide an aesthetic appearance desired by consumers.
  • the particle size distribution is defined by a relatively tight geometric standard deviation or "span” so as not to have too many particles outside of the target size. Accordingly, the geometric standard deviation is for example from 1 to 2, or from 1.0 to 1.7, or even from 1.0 to 1.4, and in particular from 1.0 to 1.2.
  • the phrase "geometric standard deviation" or “span” of a particle size distribution means the geometric breadth of the best-fitted log-normal function to the above-mentioned particle size data which can be accomplished by the ratio of the diameter of the 84.13 percentile divided by the diameter of the 50 th percentile of the cumulative distribution (D 84.13 /D 50 ); See Gotoh et al, Powder Technology Handbook, pp. 6-11, Marcel Dekker 1997 .
  • the bulk density of the particles is for example in the range of from 400 g/l to 850g/l, or from 550 g/l to 800 g/l or even from 600 g/l to 750 g/l.
  • the control of improperly sized particles via the present invention contributes to the tight span of the composition produced by the present invention.
  • the term "bulk density" refers to the uncompressed, untapped powder bulk density, as measured by pouring an excess of powder sample through a funnel into a smooth metal vessel (e.g., a 500 ml volume cylinder), scraping off the excess from the heap above the rim of the vessel, measuring the remaining mass of powder and dividing the mass by the volume of the vessel.
  • Shape of the individual particles can be measured in a number of different ways known to those of ordinary skill in the art.
  • One such method is using optical microscopy with Optimus (V5.0) image analysis software.
  • “Circularity” is defined as (measured perimeter length of the particle image) 2 /(measured area of the particle image). The circularity of a perfectly smooth sphere (minimum circularity) is 12.57; and "Aspect Ratio" which is defined as the length/width of the particle image.
  • the granular compositions of the invention may have an average circularities of at most 50, in particular from 12.57 10 30, for example at most 23, or even at most 18. Also possible are granular compositions with particles with an average aspect ratios of at most 2, in particular at most 1.5, or at most 1.3, or from 0.2 to 1.2.
  • the granular product is a detergent composition and may comprise surfactant(s).
  • the product may further comprise builders, bleaches, bleach activators, suds boosters or suds suppressors, antitamish and anticorrosion agents, soil suspending agents, soil release agents, germicides, pH adjusting agents, non-builder alkalinity sources, chelating agents, smectite clays, enzymes, enzyme-stabilizing agents and perfumes.
  • Suitable detergent composition are exemplified in EP 1776442 .
  • the granular product of this invention can be made by any particulation or granulation process.
  • An example of such a process is spray drying (in a co-current or counter current spray drying tower) which typically gives low bulk densities of 600g/l or lower.
  • Particulate materials of higher bulk density can be prepared by a continuous granulation and densification process (e.g. using Lodige ⁇ ® CB and/or Lodige ⁇ ® KM mixers).
  • Other suitable processes include fluid bed processes, compaction processes (e.g. roll compaction), extrusion and spheronization, as well as any particulate material made by any chemical process like flocculation, crystallisation sentering.
  • the granular product may be composed by from 20 to 100% for example from 50 to 90 %, or from 60 to 80% of spray dryed powder and from 0 to 80%, for example fron 10 to 50% or even from 20 to 40% of added powder.
  • Granulation processes are well known in the detergent art. Some non-limiting examples include the process as described in U.S Patent Nos. 5,489,392 . 5,516,448 to Capeci et al.
  • the product of the invention may be processed in a fluidized bed granulator with selected recycle of the improperly sized particles.
  • the present invention meets the aforementioned needs by controlling the size of the particles within the process to a greater extent than current detergent manufacturing processes. Via the present invention the amount of undersized particles or fines present in a detergent composition may be reduced via the use of fluidized bed granulation.
  • the process may comprise various alternative scenarios such as re-introduction to any combination of the fluid bed or when present, to a premixer or finishing step.
  • Undersized particles may be removed from the fluidized bed and re-introduced to the process such as to the premixer or fluidized bed or may be re-circulated within the fluid bed via the use of an internally recycling fluidized bed.
  • undersized particles are controlled via the use of an internally recirculating fluidized bed wherein undersized particles are captured before exiting the fluidized bed and remain within the bed until agglomerated to acceptable sizes.
  • Oversized or large particles may also exist wherein "large particles" are defined as particles that have a geometric mean particle diameter that is greater than 1.65 standard deviations above the chosen geometric mean particle diameter of the granular detergent composition at a given span or geometric standard deviation
  • the detergent agglomerates may be sized to separate oversized particles from detergent agglomerates in the desired range.
  • the oversized particles may be sized according to conventionally known technology such as via screening.
  • the oversized particles are then re-introduced into the process at appropriate locations in order to achieve the more uniform detergent composition as disclosed herein.
  • the control of these oversized particles leads to better overall properties of the composition such as particle density and span as described herein which contribute to the overall superiority of the detergent composition.
  • the oversized particles may be optionally milled or ground before re-introduction to the process.
  • the milling or grinding may be preformed in conventional grinding equipment as is well known in the art of detergent processing.
  • the oversized particles may be re-introduced to the process to any desired stage suitable for control of the process such as the fluid bed, the pre-mixer or series of pre-mixers or the finishing step, when present.
