Definitions

  • This invention is concerned with the provision of a method and an apparatus for mixing and dispensing materials or products, e.g. liquid to liquid, powder to powder, or liquid to powder.
  • One object of the invention is to limit the exposure of a user to the products during mixing. Protection of the user is becoming more important due to the fact that some products emit fumes during the mixing and therefore protection is important from the point of view of health and safety. Examples of products with whichcare in mixing is important are moulding compounds, two part epoxy resins and so on.
  • An important feature of the invention is to provide apparatus so adapted that once the products have been mixed, it is easier to dispense .the mixture as compared with normal known systems using tins for storing,mixing and pouring.
  • each sachet containing a product to be mixed. We then insert the product from one sachet into the other sachet substantially without allowing fumes to escape and so we mix the products in the said other sachet from which the mixture can be dispensed as required.
  • sachets 1 and 2 each contain a required amount of a product e.g. sachet 1 contains product 3 and sachet 2 contains product 4.
  • sachet is sealed at the top, sides and bottom and each sachet has an opening 5, preferably at the top.
  • the opening 5 in each sachet is sealed in any suitable manner e.g. by the provision of a closure 6.
  • Means is preferably provided to facilitate pouring of the contents of one sachet into the other for mixing purposes and for this purpose one sachet e.g. 2 may be provided with a male connector 7 and the other sachet e.g. 1 may be provided with a female connecter 8, see particularly Figure 4.
  • the sachets 1 and 2 form two separate packs which are filled either through the opening 5 or through a part of the sachet e.g. an open top that is sealed after filling.
  • the two filled packs are shown in Fig. l.
  • the .contents of one sachet can then be poured through the connectors 7 and 8 into the other sachet and the contents can be mixed e.g. by squeezing the relatively empty sachet, see Fig 3.
  • the closure can then be replaced over the opening of the sachet holding the mixture, after. disconnection of the connectors 7 and 8.
  • Fig 5 shows a single sachet, preferably of slim shape
  • Fig 6 shows the contents of the sachet shown in Fig 5 being poured into another sachet or being inserted as a whole into another sachet,
  • Fig 7. shows the sachet of Fig 5 inside another sachet
  • Fig 8 shows views of a sachet clamp
  • Fig 9 is a view similar to Fig 5 with the sachet turned through about 90°.
  • Fig 5 shows a sachet or pack 10 the top of which is clipped by the application of a clip 11 prior to cutting along the Line C which is done just before use.
  • the pack 10 contains a product 12 which it is desired to mix with a product 13 in a sachet 14 shown in Fig 6.
  • PreferabLy the cut sachet 10 is inserted through an opening in sachet 14 until it is fully inside the sachet 14, see Fig. 7.
  • the pack or sachet can then be reclosed by application of closure 15 and the cut sachet 10 is squeezed inside the pack 14 so that the clip 11 will spring off, allowing the contents 12 of sachet 10 to mix with contents 13 of pack 14 to form a mixture 16, the two materials being mixed totally enclosed within pack 14.
  • Fig 8 The preferred form of clip is illustrated in Fig 8 which shows that the clip has bifurcated arms 17, 18, which can grip the sachet, see e.g. Fig 9, and an adhesive pad 19 for attachment to the outer surface of the sachet, the pad 19 being attached to the base of the arms 17, 18 by a connector 20.
  • the packs or sachets may be made of any suitable flexible material e.g. a plastics material or a foil and any suitable form of clip may be used.
  • FIGs 10 to 16 Another modification or embodiment of the invention is shown in Figs 10 to 16 in which:-
  • Figs 10 and 11 show respectively a small sachet and a large sachet
  • Fig 12 is a detail view of a part of the large sachet
  • Figs 13 to 16 show sequential steps in the use of the sachets shown in Figs 10 and 11.
  • Figs. 10 to 16 show sachets designed particularly though not exclusively for the preparation of car body filler.
  • Figs 10 and 11 show by way of example a small sachet 21 containing a hardener compound 22 and a large sachet 23 containing powdered filler 24.
  • Fig 12 shows one form of opening for the large sachet 23.
  • the opening is formed by a hollow short tubular body 25 attached suitably to the flexible envelope of the sachet.
  • the opening is closed by a cap 26 shaped as shown in Figs 11 and 12, an annular seal being provided at 27 between the cap 26 and the body 25.
  • the sachets 21, 23 are made of relatively flexible material while the body 25 and the cap 26 are made of relatively rigid material.
  • the two sachets are preferably joined together in an easily disconnectable manner by flaps 28, 29 provided eg. with VELCRO (Trade Mark) type connectors 30, 31.
  • the cap 26 is removed from the body 25 to open the large sachet 23, the small sachet 21 is disconnected from the large sachet 23 and the small sachet 21 is opened e.g. by cutting of a corner of the sachet as shown in-Fig. 13.
  • the small sachet 21 is then inserted, cut end first, through the opening provided by the body 25 in the large sachet 23 until the small sachet 21 is completely inside the large sachet 23.
  • the small sachet may be secured in position by replacing the cap 26 in such a way that the end of the small sachet is trapped between the cap 26 and the body 25 so that the small sachet 21 is suspended inside the large sachet 23 as shown in Fig 14.
  • the walls of the large sachet 23 can then be manipulated or massaged to expel the compound from the-small sachet 21 and to mix the compound 22 with the powder 24 in the large sachet 23, see Fig. 15.
  • the contents of the large sachet having been mixed can then be expelled either by cutting off a corner of the large sachet and extruding the mixture into position ready for smoothing or by removing the cap and extruding the mixture through the body 25.
