Definitions

  • Sachets are known which provide an economical means for storing liquid products.
  • the products may be discharged when required for use by opening the sachet. Most frequently this is achieved by tearing or cutting off an edge or a corner of the sachet.
  • sachets are intended for "single use”. That is to say that once the sachet has opened a single dose is provided and the empty sachet is immediately discarded.
  • Sachets are known however which provide for multiple use, and furthermore allow the consumer to determine the amount of product dosed at each usage.
  • Examples of such sachets are those having preformed spouts with closures. Such designs of sachet permit multiple use and controlled dosing, but they are expensive to manufacture.
  • Other examples are sachets which have a discharge opening which is connected to the inner volume of the sachet by means of a discharge channel.
  • WO91/11366 published on 8th August 1991, discloses a sachet or pouch having either a "serpentine" discharge channel, or a discharge channel with spout indents in order to restrict the flow of fluid through the discharge spout. It is stated that the purpose of spout indents is to restrict the flow of fluid through the elongated spout when the pouch is not in use, as happens, for example when the pouch is left unintentionally on its side.
  • sachets which comprise at least two side walls made of a flexible material, the side walls being sealed along at least one edge to form an internal volume, the sachet in the region of the edge comprising a means for dispensing the liquid product from within the internal volume to the point of use outside the sachet.
  • the object of the present invention is to provide a more economical sachet which would permit controlled dosing, multiple use and essentially no leaking between uses.
  • a cheap manufacturing process would be of considerable value, because the sachets could be used in countries with developing economies where consumers prefer to repurchase units containing small quantities of product at more frequent intervals, and also for free sampling where units containing small quantities of product are required.
  • sachet having a dispensing means which comprises at least two, and preferably at least four, dispensing channels.
  • the sachet further comprises means to cut or tear a predetermined part of the sachet, in the region of the edge, away from the rest of the sachet so that the dispensing channels are opened, and provide direct communication between the internal volume and the outside of the sachet.
  • the dispensing channels are substantially straight, parallel, and have a length and a width wherein the ratio of the length to the width is at least 2:1, after the predetermined part of the sachet has been cut or torn off.
  • the invention also provides a method of making a sachet, comprising the steps of
  • Figure 1a shows a schematic view of a sealed sachet before opening, made according to the invention.
  • Figure 1b shows a schematic view of the sachet of Figure 1a after opening.
  • Figure 2a shows a schematic view of another embodiment of a sealed sachet before opening, made according to the invention.
  • Figure 2b shows a schematic view of the sachet of Figure 2a after opening.
  • the sachet of the present invention is provided along one edge with multiple narrow channels which are preferably straight and oriented in parallel. Liquid product is dispensed by squeezing the sachet forcing liquid out through the channels. When pressure is released, the narrow channels provide sufficient resistance to the product flow, thereby preventing further product being discharged until the next usage.
  • the sachet can be used to provide a dosage controlled by the user and can be stored by laying it on a surface without unwanted leakage, finally the sachet can be reused several times until completely empty.
  • Flexible sachets and pouches useful in the present invention may be of any shape, but are most commonly square or rectangular. Square or rectangular sachets and pouches are generally preformed by sealing, or optionally folding, along three edges. The remaining, unsealed edge provides an open ended mouth for filling.
  • the preform may consist of two separate polymeric films which are sealed together along three edges.
  • the preform may consist of a single piece of polymeric film which is first folded, the fold forming a first edge, and then sealed along two other edges.
  • a length of polymeric film is first folded and sealed along its length to form a tube. The tube is then cut into predetermined lengths and one end of the tube is sealed to form the preform.
  • Sealing operations may be carried out by any conventional means including heat sealing (which is most preferred), ultrasonic welding, high frequency sealing and glueing.
  • the preform is then filled using conventional filling equipment.
  • the forming of the preform, and the filling are carried out immediately sequentially on one machine, or on adjacent machines.
  • This is known as "form-fill” or "form-fill-seal".
  • Both vertical form-fill machines and horizontal form-fill machines are sold by equipment manufacturers. Vertical form-fill machines being preferred for use in the present invention in particular with liquids because this allows for multiple lanes in a side-by-side configuration, and consequently higher filling rates.
  • the sachets or pouches may be made from any suitable flexible material, in particular polymeric film, including high- or low-density polyethylene (HDPE; LDPE), polyethylene terephthalate (PET), polypropylene (PP), polyamide, polybutadiene, polybutylene polymers and copolymers, copolymers of ethylene and vinyl esters, polymers of vinyl chloride, and polymers of styrene.
  • polymeric refers to copolymers and terpolymers as well as to homopolymers.
  • laminated materials may be used.
  • the only essential requirement of a laminate is that at least one side of the laminate consists of a polymeric film which is suitable to be sealed.
  • laminated film comprising PET, polyamide, aluminium or paper in the outer layer, and polyethylene in the inner layer.
  • the sachets or pouches preferably have a capacity of less than 250 ml, and preferably 100 ml or less.
  • the liquid product may be any of a variety of products: examples are dish washing liquid, laundry detergent, household cleaner, shampoo, shower gel, moisturising cream, as well as foodstuffs such as tomato sauce, salad cream, mustard etc.
  • the optimal size of the dispensing channels will depend on product viscosity, surface tension and dosage requirements, as well as on the overall dimensions of the sachet, and the stiffness of the material of the side walls.
  • the dimensions of the channels can be easily selected to provide for optimal dosage for any given liquid product, as well as to ensure little or no leakage of product between uses.
  • the channels are conveniently located in the region of the middle of any one of the edges, preferably the shortest edge, but they may also be located towards one of the corners of the sachet.
  • a means to cut or tear a predetermined part of the sachet away from the rest of the sachet may be a notch in one edge of the sachet in the position where the tear should be initiated, for example a V-shaped notch; or it may be a line of weakness formed for example by creasing, scoring or perforating the flexible film along the line that the tear should lie. Alternatively the line may be printed or otherwise marked on the outer surface of the flexible film to indicate where it should be cut.
  • Figure 1a shows a flexible polymeric sachet made according to the present invention.
  • the sachet 10 comprises two films 12, 13 which are sealed together along four edges 14, 15, 16, 17.
  • Figure 1b shows the sachet after a predetermined part 19 of the sachet, in the region of the edge 14, has been cut or torn away from the rest of the sachet so that the four dispensing channels 18 are opened, and provide direct communication between the internal volume and the outside of the sachet.
  • the length of the dispensing channels after cutting or tearing in a particularly preferred example is 6 to 12 mm, and the width is 2 to 6 mm.
  • FIG 2a shows a flexible polymeric sachet made according to the present invention.
  • the sachet 110 comprises a single film folded 117 to form two side walls 112, 113 which are sealed together along three edges 114, 115, 116.
  • Figure 2b shows the sachet after a predetermined part 119 of the sachet, in the region of the edge 114, has been cut or torn away from the rest of the sachet so that the dispensing channels 118 are opened, and provide direct communication between the internal volume and the outside of the sachet.
  • the dispensing channels 118 are not parallel but are oriented to direct the product towards a point outside the sachet.
