Definitions

  • the present invention refers to a flexible container for products normally in a gelatinous state, which must be kept separate from one another and mixed immediately before use.
  • the products in question can be two substances which, after mixing, form a thermosetting product which can be used, for example, to make perfectly tight connections of electrical cables, for example in desert regions.
  • such containers consist of bags or envelopes of plastic material, with an intermediate transverse closure, so as to define two separate compartments, able to receive the corresponding products.
  • the container designated with reference numeral 1
  • the container is obtained from a tube, which before closure at both ends, is clamped in a transverse median area between an elastic element 2 of iron or plastic, substantially circular in section, and a corresponding rod 3, of relatively soft material, for example rubber.
  • the tube 4 being clamped between the elements 2 and 3, determines a separation of the container into two compartments, indicated respectively with 5 and 6, which are open at the respective ends, to be able to be filled with the corresponding products, and subsequently sealed along the welding lines denoted by reference numerals 7 and 8.
  • the rod 3 protrudes at least from one side of the container 1, so as to allow the elastic element 2 to be gripped and withdrawn when the products have to be mixed. Once the rod has been withdrawn, the elastic element 2 can also be removed, thus placing the two compartments 5 and 6 in communication for mixing the products.
  • the object of the present invention is to eliminate the above-mentioned drawbacks, providing a container in flexible material for products that are to be kept separate and mixed before use, that is extremely simple to make, cheap, reliable and above all does not have additional external elements.
  • the container according to the invention has, in the area of delimitation between the two compartments containing the respective products, a strip of easy-open material, which holds the two walls of the container together during storage and transportation but allows separation thereof when the two products must be mixed, for example by exerting pressure on at least one of the compartments containing said products.
  • the strip of easy-open material which is of the same material as the inner layer of the walls of the container, for example polyethylene or modified polypropylene, advantageously extends to the side edges of the container, in order to make the weld in said area stronger. Therefore, to avoid the risk of possible loss of the tight seal at the side edges of the strip, the welds of the side edges of the container in this area have a triangular shape which joins up to said strip of easy-open material.
  • the two compartments can be left open at the opposite head ends of the container or at the same side of the container, depending upon the type of filling that is to be done.
  • a flexible container according to the invention shown in its final form in Figure 3, is designated as a whole by reference numeral 10.
  • said container has a substantially rectangular shape, and is divided along the centre line into two separate compartments 11, 12 intended to receive two products to be mixed immediately before use.
  • the material making up the container 10 is a multi-layer material, with at least one weldable inner layer, for example in polyethylene or polypropylene, so as to be able to obtain the container 10 by means of welding along the edges of sheets or rectangular walls 13, 14, visible in particular in the section of Figure 6.
  • the container 10 is formed by making a weld along the perimeter of the rectangular walls 13, 14, leaving some sides unwelded to allow the products to be introduced into the respective compartments 11, 12 and subsequently closing said sides. This can be done in the manner that will be better described hereinunder, with reference to the embodiments illustrated in Figures 4 and 5 respectively.
  • a strip 15 of easy-open material that is of a material of the same type as that of the inner layer of the walls 13, 14, thus polyethylene or polypropylene, suitably modified, so that a weld in the area where said material is disposed is not permanent, but allows separation of the welded walls 13, 14 when a certain force is exceeded.
  • the strip 15 of easy-open material is disposed between the two opposite walls 13, 14 and then the welds which allow the two open compartments 11, 12 to be obtained are made.
  • two side welds 16, 17 are made along the entire length of the container, obviously besides a transverse weld on the strip of easy-open material 15.
  • respective openings 18, 19 remain, at opposite head ends of the container 10, for filling of the compartments 11, 12, openings that are subsequently closed, after filling of the container, with weld lines 20, 21.
  • the strip of easy-open material 15 may only partly involve the line of separation between the two compartments 11, 12, so as to allow the passage of products from one compartment to another in any case during the mixing stage.
  • the container thus realized allows mixing of the products contained in the compartments 11, 12 before use, by breaking the line of separation obtained along the strip of easy-open material 15, by exerting a certain pressure on at least one of the compartments 11, 12.
  • Figure 5 shows a different method of forming the container 10, whereby two welds 20, 21 are first made along the head sides of the container, whereas the lateral weld 17 is made after filling of the compartments 11, 12, which in this case takes place through openings 18' and 19' provided on the same side of the container.
  • the container 10 is made by forming a vertical tube, welding along the edges 20, 21 and after cutting, making the bottom weld 16, so that the container has the two compartments 11, 12 with the respective openings 18', 19' facing upward, in order to be able to be filled at the same time by means of two respective nozzles.
