Definitions

  • the present invention relates to a package for containing tablets of detergent that comprises a child deterrent means.
  • Flow-wrap unitary packages for containing at least one tablet of detergent are representative of the various flow-wrap packages to which the present invention can apply; such packages are typically made, for example, out of a plastic, or paper-coated film that is folded and longitudinally sealed, so as to form a tube into which at least one unit of a consumer product, for example a detergent tablet is inserted. The tube is then closed at each of its two distal extremities by means of distal seals that are perpendicular to the longitudinal seal. Furthermore, due to the packing process, the unitary packages are produced from a continuous film, and so they are separated by distal cuttings that are made in the region of the distal sealings.
  • Flow-wrapped packages are well-known and used in the art.
  • One example is disclosed in international application WO 97/02993 published January 30, 1997. It discloses a tear open flow-wrapped package for packing of pool chemicals or other flowable chemicals.
  • Such unitary flow-wrap packages when used for packing tablets of consumer products, for example detergent tablets are typically made as described above.
  • Detergent tablets generally use a composition of chemical compounds that can be dangerous if ingested. This is particularly true in the case of young children that tend to be attracted by small flow wrap unitary packages, and that are more likely to try and open the package, access the tablet and bite/ingest it.
  • the effect of chemicals may be even more damaging for their health.
  • the unitary tubes are usually formed from a long roll of film, then filled with tablet(s). They are then sealed and cut to be separated from each other.
  • the cuttings at the distal ends of one unitary pack usually contain indentations that are to be used by the consumer as facilitating means for opening by hand.
  • facilitating means also facilitates access to the tablet for young children, and thus increases the risk of poisoning.
  • One means that has been applied to avoid such poisoning is the use of non-oriented packaging films. Such films are known as being difficult to tear open without using a tool, or without applying a tearing strength such that it shall be applied only by an adult.
  • a flow-wrap package for containing dangerous products that is made out of a non-oriented film, so as to discourage children from opening it by tearing, but that is still easily openable by adults.
  • Some packages are known in the art which are made out of a non-oriented film (i.e., a film with tear-resistant properties), said packages being opened only by peeling off the sealings in the extremities of the package.
  • the present invention is directed to a flow-wrapped package for containing at least one unit of a consumer product, preferably at least one tablet of a consumer product, and most preferably at least one tablet of a laundry or cleaning detergent composition.
  • Said package is made out of a non-oriented film, thus having high tear-resistant properties.
  • a means is provided which helps an adult user to grab each side of a seal and exert coordinated pulling movements for peeling off the seal and open the package. This means is achieved by providing at least two opposite sides of said flow-wrapped package with longitudinal seals that are to be unfolded and grabbed by the user.
  • a package (1) that comprises a package body (10) and at least two distal ends (11).
  • the package is made out of any suitable material with high tear-resistant properties. It can be for example coated paper, metal, or plastic. It can be made out of one single material or out of a combination of several materials.
  • the package is made out of a non-oriented thermoplastic film, such as for example non-oriented polyethylene or polypropylene.
  • a non oriented film is defined as a film which exhibits a tear propagation force above 3 Newton where the tear propagation force is measured with the Trouser tear method described in ISO 6383 (published in 1983).
  • the package can also be made out of a laminate.
  • the packaging material must be suitable for forming a peel seal, that is to say, it must be sealable on itself and form a fusion seal which is peelable.
  • the package can have any size that is suitable for containing at least one unit of a consumer product that is considered as dangerous, such as for example detergent compositions, pesticides, insecticides, or medicines.
  • Said unit is either non particulate solids such as tablets or briquettes or bars, or under the form of a powder or granulates, or even under a liquid form.
  • the package is intended to be used for containing at least one detergent tablet (2) for use in laundry or dish-washing purposes.
  • Such tablets (2) are usually considered as dangerous consumer products, if ingested.
  • Said tablet (2) may have any suitable shape, but is preferably symmetrical so as to ensure complete and uniform dissolution in the wash liquor during the wash cycle.
  • the detergent may be of any suitable composition, and may comprise for example surfactants, suds suppressors, bleaches, builders, enzymes, fillers, and perfumes.
  • a unit of a consumer product such as a unit of detergent product is typically defined as a dosed quantity of said detergent suitable for use during one wash cycle.
  • a dosed quantity of said detergent suitable for use during one wash cycle.
  • the user will put one tablet inside the washing machine that will dissolve during the wash cycle, with action onto the dishes or the clothes, for example.
  • more than one unit may be used for one wash cycle, for example in extreme dirtiness of items to wash, amount of items to wash, or hardness of water.
  • the overall shape of the package (1) may vary, for example the package (1) can be flat, when the distal sealed extremities (11) are parallel (i.e. located along the same plane), as shown in figure 2.
  • the package once filled and closed, may have a different shape that is determined by the shape of the contents, for example a substantially parallelepipedic shape, as shown in figure 2.
  • Another example of shape is shown in figure 3: the package (1) is tetraedric, when the distal sealed extremities (11) are located in perpendicular planes. In the latter case, the package substantially comprises four sides opposing each other by pairs.
  • the package (1) comprises at least two longitudinal sealings (14), each being located on one of at least two sides of the package (1), as shown for example in figure 2. Said at least two sides are preferably sides that are opposite by pairs.
  • the position of said longitudinal sealings across one side of the package (1) may vary.
  • each longitudinal seal is substantially centered across the width of one side of the package (1), so that they are substantially aligned in a plane that is perpendicular to the sides that contain said longitudinal sealings.
  • the width of said longitudinal seals (14) may vary, but is preferably not less than 5mm, and more preferably not less than 10mm.
  • the longitudinal seals (14) are preferably flat-folded onto the surface of the package (1), as shown in figures 2 and 3. During the opening operation, the user shall unfold said longitudinal seals (14), as shown in figure 1, so as to grab and pull them in opposite directions to peel the distal seal (17) off.
  • the package further features distal sealings (17) located at the distal ends (11) of the package (1).
  • the distal sealed ends (11) of the package (1) also comprise distal cuttings that are made during the manufacturing process (see description below).
  • Said distal cuttings (13) can have several shapes, for example they can comprise indentations, as shown in figures 4 and 5.
  • the distal cuttings (13) are rectilinear cuttings, as shown in figures 1, 2 or 3. Such rectilinear cuttings (13) prevent accidental opening by tearing the film, since no weak points along the border of the film could be used as a pre-cut.
  • the opening of the package requires coordinated movements for grabbing opposed longitudinal seals, pulling them in opposite directions (see figure 1), and peeling off the seal opened.
  • coordinated movements are to be applied by adults, but it has been shown that such coordinated movements are almost impossible to make for a young child.
  • the package of the present invention is child-deterrent, while being constructed so that opening by peeling one distal seal is easy to perform by adults.
  • the package is made out of a film that is closed by sealing, and preferably a flow-wrapped package.
  • a description of two examples of a process for making a flow-wrap package according to the present invention will now be made, with reference to figures 4 and 5.
  • the package is made out of a single piece of film. The steps of such a process are, in order:
  • the package is made out of two separate pieces of film.
  • the steps of such a process are, in order:
  • powders, or liquids are most preferably filled in a tube that is vertically formed, filled and sealed, while solid contents is generally fed in a tube that is vertically formed filled, and sealed.
  • the sealings either the longitudinal ones (14), or the distal ones (17) can be made by means of hot sealing, or by cold sealing or any other suitable sealing process, such as for example induction sealing or ultrasonic sealing (in case the nature of the packaging material allows such process).
  • Cold sealing is performed by using the properties of the packaging film to stick onto itself, or by using a cold glue with excellent tacking properties, so that no heat is required for the sealing, but only pressure applied by the sealing jaws.
  • the sealings of the package are hot-sealings. Both cold and hot sealing processes are well-known in the art.
  • the packaging material is made out of several layers, for example a thermoplastic laminated material, and if the inner and outer layers are not of the same nature, the surfaces of material to be applied onto each other and sealed shall be chosen so as to perform a seal of good quality. Any person skilled in the art shall be able to select compatible materials so as to perform a correct seal. Depending on the chemical nature of the inner/outer layers of a laminate, the seal shall be made between inner and outer layers, between two inner layers, or between two outer layers.
  • the sealings shall preferably be made such that peeling the seal off, requires tearing strength and movements coordination that cannot be applied by a young child, but only by an adult. It is not the purpose of the present description to give the appropriate parameters for achieving such sealings, since such parameters can be determined and applied by a person skilled in the art.
